Description
Technical Field
The invention relates to the field of anode carbon block detection equipment, in particular to equipment and a method for classifying and detecting carbon block mixture based on a viscous effect.
Background
The anode carbon block is a very common application product in an electrolytic cell, and is shown in figure 8 of the specification, and is a structural schematic diagram of the anode carbon block, wherein the main raw materials in the anode carbon block are a mixture of calcined petroleum coke and asphalt, wherein the asphalt is used as an adhesive, and the calcined petroleum coke is used as a main acting material of the anode carbon block. And after the mixture of asphalt and calcined petroleum coke is mixed, the anode carbon block is obtained through extrusion molding, and the anode carbon block is baked to obtain a finished product of the anode carbon block, so that the anode carbon block can be used as the anode end of the electrolytic cell.
After the anode carbon block is baked, the mixture of the calcined petroleum coke and the asphalt material is required to be mixed uniformly, and then the mixture can be molded. However, between the steps of mixing the asphalt material and the calcined petroleum coke, the calcined petroleum coke is required to be crushed, namely, the whole calcined petroleum coke is crushed and sieved, so that anode carbon blocks with different sizes are obtained, and calcined petroleum coke particles with different sizes are stored in bins. When the anode carbon block is used, calcined petroleum coke particles with different sizes are required to be mixed with asphalt according to different proportions, so that the prepared anode carbon block can be ensured (because the prepared anode carbon block is required to be used as an anode end of an electrolytic cell, but the conductivity and the resistivity of the calcined petroleum coke particles with different sizes are different, when the mixture is prepared before the anode carbon block is molded, the calcined petroleum coke particles with different sizes and different proportions are required to be mixed), and the following problems can occur according to the mixing mode of the calcined petroleum coke particles and the asphalt:
1. The existing proportion mode adopts a weighing mode to select calcined petroleum coke particles, and in order to ensure the viscosity of asphalt materials, the mixing and the conveying of petroleum coke particles are required to be carried out in a high-temperature environment, and the combination condition inside the anode carbon blocks can be detected only after the anode carbon blocks are prepared. The method can detect the anode carbon blocks after the anode carbon blocks are formed, and the production and forming of the anode carbon blocks are carried out in a high-temperature environment without stopping, so that the detection result cannot be known for the first time, and when the proportion of the mixture in the formed anode carbon blocks does not meet the production standard, a batch of anode carbon blocks which do not meet the forming standard are prepared and formed, so that the raw materials are wasted.
2. Because different calcined petroleum coke particles need to be subjected to the warehouse separation treatment, when the size mixing proportion of the calcined petroleum coke particles in the anode carbon blocks obtained by detection is incorrect, the storage bins of a plurality of calcined petroleum coke particles need to be adjusted, namely the overall proportion of the calcined petroleum coke mixture is changed. However, the mixing equipment is burdened by the method, and once the mixing debugging proportion of the calcined petroleum coke is incorrect, the whole production line of the anode carbon block is required to be shut down, and the mixing equipment is cleaned and then is subjected to proportional debugging again, so that the mixing debugging process of the anode carbon block is extremely complex.
Based on the problems, the classification detection equipment and the detection method for the carbon block mixture based on the viscosity effect are needed, and judgment can be carried out according to the viscosity conditions of different anode carbon block mixtures, so that whether the additive amount of the anode carbon block mixture meets the addition standard in different stages is detected, the calcined petroleum coke grain proportion of different sizes in the mixture meets the production requirement of the anode carbon block, and the produced anode carbon block meets the preparation standard is further ensured.

Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Further, it will be understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the application, and equivalents thereof fall within the scope of the application as defined by the claims.
On the premise of preparing the anode carbon block, calcined petroleum coke particles with different sizes and asphalt are required to be mixed in proportion and then conveyed into a forming die for extrusion forming, and then the extruded anode carbon block is baked, so that the anode carbon block meeting the production standard is prepared. If the mixing proportion of the carbon block mixture before molding is inconsistent or the mixture is unevenly mixed, the quality of the prepared anode carbon block is directly affected, and the problems of the existing mixing equipment and the mixing conditions are also mentioned in the above description, such as the following:
1. The existing proportion mode adopts a weighing mode to select calcined petroleum coke particles, and in order to ensure the viscosity of asphalt materials, the mixing and the conveying of petroleum coke particles are required to be carried out in a high-temperature environment, and the combination condition inside the anode carbon blocks can be detected only after the anode carbon blocks are prepared. The method can detect the anode carbon blocks after the anode carbon blocks are formed, and the production and forming of the anode carbon blocks are carried out in a high-temperature environment without stopping, so that the detection result cannot be known for the first time, and when the proportion of the mixture in the formed anode carbon blocks does not meet the production standard, a batch of anode carbon blocks which do not meet the forming standard are prepared and formed, so that the raw materials are wasted.
2. Because different calcined petroleum coke particles need to be subjected to the warehouse separation treatment, when the size mixing proportion of the calcined petroleum coke particles in the anode carbon blocks obtained by detection is incorrect, the storage bins of a plurality of calcined petroleum coke particles need to be adjusted, namely the overall proportion of the calcined petroleum coke mixture is changed. However, the mixing equipment is burdened by the method, and once the mixing debugging proportion of the calcined petroleum coke is incorrect, the whole production line of the anode carbon block is required to be shut down, and the mixing equipment is cleaned and then is subjected to proportional debugging again, so that the mixing debugging process of the anode carbon block is extremely complex.
Therefore, the carbon block mixture needs to be effectively detected to ensure that the produced anode carbon block meets the production standard so as to meet the production requirement specified by a manufacturer. Because the viscosity of the carbon block mixture obtained by mixing calcined petroleum coke particles with different proportions is inconsistent in a specified temperature environment, for example, the small-size coke particles have a large proportion and the large-size coke particles have a small proportion, the viscosity of the mixed carbon block mixture is larger than that of the standard carbon block mixture, and therefore, the mixing proportion of the carbon block mixture can be judged to be correct by detecting the viscosity of the carbon block mixture, and the proportion of the coke particles in the carbon block mixture is adjusted according to the detected viscosity information of the carbon block mixture.
Thus, the following structural settings were made:
Carry out hierarchical check out test set of charcoal piece mixture based on viscous effect, including mixture conveying mechanism 1, mixture detection mechanism 2, when setting up here, through carrying out the setting of mixture conveying mechanism 1 and mixture detection mechanism 2 to reach the demand to charcoal piece mixture transport and detect. Since the viscosity of the carbon block mixture is relatively high even though the mixture viscosity is relatively low due to inconsistent mixing ratios, the arranged mixture conveying mechanism 1 is required to effectively convey the carbon block mixture and avoid the problem of adhesion of the mixture with a relatively large area, and the arranged mixture conveying mechanism 1 is required to ensure that the carbon block mixture can be conveyed to the mixture detecting equipment in a relatively small adhesion state. The device for detecting the mixture is used for detecting the acting force of the carbon block mixture sprayed out of the conveying shell 3, and for the carbon block mixture with standard viscosity, after the specified acting force is conveyed to the conveying shell 3 and the acting force is overcome to the inner wall of the conveying shell 3, the acting force applied to the mixture detecting device after being sprayed out of the outer end position of the conveying shell 3 is in a certain range, so when the viscosity of the carbon block mixture is changed, the acting force between the carbon block mixture and the inner wall of the conveying shell 3 is changed, and the acting force of the carbon block mixture applied to the mixture detecting device is changed to judge the specific change condition of the viscosity of the mixture, the following specific structural arrangement is needed for the principle:
The mixed material conveying mechanism 1 is communicated with anode carbon block mixed material stirring equipment and comprises a conveying shell 3 and a high-pressure power source, wherein the high-pressure power source is connected with the conveying shell 3, when the high-pressure power source conveys fluid towards the interior of the conveying shell 3, carbon block mixed material in the anode carbon block mixed material stirring equipment is sucked into the interior of the conveying shell 3, the conveying shell 3 is an ejector conveying assembly 5, the ejector conveying assembly 5 comprises a sucking pipe 6 and an ejecting pipe 7, the sucking pipe 6 comprises a tip sucking port 8 and a sucking outer pipe 9, the tip sucking port 8 is arranged in the sucking outer pipe 9, a sucking port 10 is arranged on the sucking outer pipe 9, the ejecting pipe 7 comprises a butt joint end 11 and an ejecting end 12, and when the sucking pipe 6 is in butt joint with the ejecting pipe 7, the tip sucking port 8 is in non-contact abutting joint with the butt joint end 11. When the high-pressure power source is used for carrying out high-speed fluid delivery towards the inside of the delivery shell 3, the mixture in the stirring cavity communicated with the delivery shell 3 is sucked into the delivery shell 3 due to the fact that the higher the flow speed is, the smaller the pressure is, and therefore the material taking and delivering operation of the carbon block mixture is achieved. In the setting, the ejector conveying component 5 is selected as the conveying shell 3, in the setting connection, a high-pressure power source is connected with the position of the feed port end of the tip suction port 8 and is used for conveying fluid into the tip suction port 8, a channel connected with the stirring cavity is connected with the suction port 10 of the suction outer tube 9, when the high-pressure power source conveys high-speed fluid into the tip suction port 8, the high-speed fluid is ejected from the position inside the tip suction port 8, at the moment, the fluid flow speed at the ejection position of the tip suction port 8 is high, the pressure at the suction port position of the suction outer tube 9 is high, so that air at the suction port 10 is sucked and flowed towards the position of the tip suction port 8, and carbon block mixture in the stirring cavity is sucked into the suction outer tube 9 and moves along with the fluid sucked by the tip suction port 8. Fluid ejected from the tip suction port 8 and the carbon block mixture sucked into the suction pipe 6 are ejected to the position of the abutting end 11 of the ejection pipe 7 and ejected outward from the position of the ejection end 12 of the ejection pipe 7.
The mixture detection equipment is matched with the mixture conveying mechanism 1 and comprises a pressure sensing assembly 4, wherein the pressure sensing assembly 4 is matched with the outlet end position of the conveying shell 3, and when the high-pressure power source conveys the carbon block mixture through the conveying shell 3, acting force is generated on the pressure sensing assembly 4. The pressure sensing assembly 4 comprises pressure sensing sensors, a plurality of pressure sensing sensors are closely arranged, the arrangement direction of the pressure sensing sensors is towards the outlet position of the conveying shell 3, and each pressure sensing sensor is independently connected with a control system. The pressure sensing assemblies 4 are arranged to ensure that the impact acting force of the fluid and the carbon block mixture is detected, the pressure sensing assemblies 4 are connected with the control system, pressure information is sensed by the different pressure sensing assemblies 4 and transmitted to the control system, the control system processes the pressure information, and accordingly the specific stress condition of the fluid and the carbon block mixture on the pressure sensing assemblies 4 is judged, and the viscosity condition of the carbon block mixture is analyzed.
The principle of the above-described structural arrangement is explained as follows:
when the high-pressure power source delivers a specified flow rate of fluid into the delivery casing 3 in a unit time, the kinetic energy possessed by these fluids is fixed;
That is to say, Where E is the total kinetic energy delivered by the high pressure power source, m is the mass of the fluid delivered per unit time, and v is the velocity of the fluid, where it should be understood that the above is the total kinetic energy of the fluid entering the tip suction port 8, and the friction energy consumed inside the tip suction port 8 is negligible (since this part of energy is easily known by controlling the variable method, whether to calculate or not does not affect the final measurement result);
Because the greater the viscosity and the greater the force between the contacts for different viscous mixtures, the different doses will be drawn during the drawing process. Therefore, when fluid enters the inner part of the pumping outer pipe 9 from the position of the pumping port 10, the mixture is pumped into the inner part of the pumping outer pipe 9 in different dosages because of different viscosity, and most importantly, whether the viscosity of the mixture meets the mixing requirement can be primarily judged according to the dosage of the mixture pumped into the inner part of the pumping outer pipe 9;
when the fluid carries the mixture into the jet pipe 7, an adhesion effect is generated between the fluid and the inner wall of the jet pipe 7 due to the viscosity of the mixture, so that the fluid is prevented from carrying the mixture to be jetted outwards from the position of the jet end 12 of the jet pipe 7, and the kinetic energy of the fluid and the mixture jetted from the position of the jet end 12 of the jet pipe 7 is influenced;
That is to say, ;
In the case of the above-mentioned type of device,Indicating the energy expended by the fluid and the mix in the jet pipe 7,Represents the kinetic energy of the fluid and the mixture when being ejected from the ejection end 12 of the ejection tube 7The sum of the mass of the fluid and the mixture at the discharge end 12 of the discharge tube 7,A square representing the ejection velocity of the ejection end 12;
As known from the above equation, when the viscosity of the mixture is greater, The larger the resulting output kinetic energyThe smaller the kinetic energy of the fluid and the mixture at the discharge end 12 of the discharge tube 7, the smaller the force acting on the pressure sensing assembly 4. It should be noted here that, during the pumping of the carbon block mixture by fluid delivery, the mass of the mixture pumped out is uncertain for viscosity reasons, i.e. the more viscous the pumped out the mass of the mixture is, the less viscous the pumped out the quantity of the mixture is, so for the pumped out quantity of the mixture, a weighing device is arranged in the stirring chamber connected with the delivery casing 3, and the quantity of the mixture entering the interior of the delivery casing 3 of the stirring chamber is weighed by the weighing device, so that the problem of one of the unknown variables is solved, and the final output speed is calculated easily;
when a fluid and a mixture exert a force on the pressure sensing component 4, the impulse calculation formula is as follows:
;
The specific value of the pressure applied by the pressure sensing component 4 can be obtained, so that the final fluid and mixture speed information can be obtained by measurement and brought into In (3) can obtain the adhesive lossAnd the energy is used for judging the viscosity information of the carbon block mixture.
The following optimization settings are carried out on the theoretical and structural settings:
1. For the structural arrangement of the discharge pipe 7, it is necessary to ensure that the discharge pipe 7 can smoothly spray the fluid and the mixture, and at the same time, it is also necessary to ensure that the fluid and the mixture can effectively enter the discharge pipe 7, so that when the arrangement is performed, the abutting end 11 of the discharge pipe 7 is a smooth inclined surface, and the tip suction port 8 is located at a deep position of the smooth inclined surface after being matched with the abutting end 11, so as to ensure that the fluid and the mixture can effectively enter the discharge pipe 7, and avoid the problem of conveying the fluid and the mixture. After the inside of the discharge tube 7 passes through the smooth inclined surface of the abutting end 11, the inner wall of the discharge tube 7 gradually expands and extends to the position of the discharge end 12 of the discharge tube 7, and the purpose is to ensure that the fluid and the mixture can be effectively discharged from the position of the discharge end 12 of the discharge tube 7. And, the spraying end 12 of the spraying pipe 7 is provided with a spraying port 13 in a matching way, so that the fluid and the mixture can be accurately sprayed outwards from the spraying end 12 of the spraying pipe 7.
2.
