Description

Lifting and removing apparatus for floating matter of sewage and waste water disposal plant

The present invention relates to a device for lifting and removing a contaminant that is installed at a waterway inlet where sewage and wastewater flows in a sewage and wastewater treatment plant. The present invention relates to a device for lifting and removing a contaminant that allows the lifting and removing process to be automated in accordance with a smooth flow path maintenance and level difference.

In general, sewage and wastewater treatment plants use biochemical oxygen demand and chemical treatment to treat various domestic and industrial wastewater.

In recent years, the biochemical treatment method using microorganisms is preferred to the chemical treatment method using chemicals, which is due to the tendency of the times to worry about the third contamination by chemicals. In addition, the biochemical treatment method has the advantage that the microorganisms used as a fertilizer can be recycled as follows.

In the biochemical treatment method, the degree of contamination of sewage is represented by B · O · D PPM, which is a microorganism, ie, aerobic virus, is injected into a certain amount of sewage and contained in sewage by the virus. In order to decompose organic matter, the degree of contamination is recognized by a number indicating how much oxygen is required for aerobic virus reproduction.

Prior to the sewage and wastewater treatment process using the biochemical treatment method, a process for removing contaminants, sedimentation and sediment which cannot be decomposed by aerobic virus is preceded.

In other words, the various sewage and industrial wastewater from the streams are collected beforehand into the waterways of the sewage and wastewater treatment plants. The removal process and the removal process of sedimentation and sediment, such as earth and sand deposited on the bottom of the channel, are performed.

As described above, the prior art for the process of lifting and removing the contaminants related to the present invention during the water purification process in the sewage and wastewater treatment plant is installed at the inlet of the water inlet to which the sewage and wastewater flows into the water by a rake raised from the bottom of the waterway. A debris removal device has been preceded to allow debris to be lifted and removed. However, the conventional dust removal device using a rake is a device that is lifted and removed once in one cycle, and it is impossible to automate the lifting and removing process. There was a disadvantage in that the removal process and manufacturing cost increase.

In another conventional art, an apparatus for removing a contaminant using a stepped step screen has been previously proposed. The power was transmitted from the drive motor to rotate the rotating screen in the staircase fixed screen was to lift the contaminants to the upper step, that is, the upper step.

However, it is very difficult to lift a contaminant having a size (area) beyond the width of the step screen, such as vinyl, wood chips, cloth cloth, etc. using the conventional step screen.

In other words, the scaffold should be continuously lifted to the upper stair by the rotating screen which arcs on the fixed screen, and the rotating plate is sloppy at the bottom of the trap, or the fibrous type of soil or soil is tangled or pinched on the rotating plate. Occurrence of the case resulted in a decrease in the efficiency of the lifting and removing process due to the inability to lift the operation.In addition, there were secondary disadvantages such as flow path blocking and vortex formation that prevent the smooth flow of sewage in the channel. .

The present invention is to solve the drawbacks of the prior art as described above, the inflow of sewage, in particular, a large area of contaminants introduced with the sewage and wastewater at the inlet of the sewage and wastewater treatment plant is efficiently lifted and maintains a smooth flow path The purpose is to provide a device for lifting / removing contaminants that allows the lifting and removing process to be automatically and controlled according to the water level difference.

The present invention for achieving the above object, from the drive motor installed on the outside of the waterway to efficiently lift the inputs of sewage, especially a large area of the contaminants introduced with the sewage, wastewater at the inlet of the sewage and wastewater treatment plant Conveyor having a chain-type endless track that rotates by receiving power, and partly extends to the bottom of the channel, and a plurality of flow paths, each mounted on each chain connection part of the conveyor, to guide the flow of sewage to maintain the flow path. The perforated perforated plate screen, a fork-type scraper mounted on each perforated plate screen, and the contaminants lifted and taken out by the scraper, and the blockages in the passage holes of the perforated plate screen after being removed by the scraper The rotary brush mounted on the upper side of the conveyor and the rotary brush As there is a characteristic such that the motor is provided.

In addition, the present invention detects the water level difference between the water inlet and the water outlet at which the sewage and wastewater flows, and if the water level is higher than the set water level, the rapid lifting and removing process according to the RPM control of the driving motor is automatically and controlled at the water inlet and the water outlet. It is characterized in that it is further provided with a level sensor for detecting the level difference, and a control unit for controlling the RPM of the drive motor by the output signal according to the level sensor of the level sensor.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The apparatus for lifting and removing the contaminant of the present invention is a chain type that rotates while receiving power from a driving means installed outside the waterway in a waterway of a wastewater treatment plant, as shown in FIGS. 1 to 6a and 6b. Perforated plate screen 12 having a crawler 10 and a plurality of flow holes 16 mounted on each chain connection part of the conveyor 10 to guide the flow of sewage to maintain the flow path. And a plurality of fork-type scrapers 14 attached to the above-mentioned perforated plate screens 12 to lift and carry out the contaminants.

In addition, the rotary brush 18 and the motor mounted on the upper side of the conveyor 10 so as to penetrate the blockage of the passage hole 16 of the perforated plate screen 12 after the contaminants lifted by the scraper 14 are taken out. 20 is provided.

As shown in FIGS. 6A and 6B, the scraper 14 is integrally formed with a plurality of pieces welded to the perforated plate screen 12 and arranged at equal intervals.

In addition, the perforated plate screen 12 is a round iron plate, the passage hole 16 to be drilled therein may be a variety of perforations in a variety of circles or polygons, but not enough to interfere with the smooth flow of sewage, especially this It is not limited.

And, each of the flow path holes 16 are arranged in a staggered arrangement of a plurality of holes at equal intervals and the diameter of each flow path hole 16 is not limited, but ease of operation in the post-settling removal step To this end, various diameters may be selected in consideration of the particle size of the sedimentation passing through the passage hole 16, and the passage hole 16 may be compatible with a plurality of perforated plate screens 12 perforated for each diameter.

In addition, as shown in Figs. 1, 2, 7, and 8, the conveyor 10 having the caterpillar of the chain type has a drive shaft 2 connected to a drive means installed outside the waterway, that is, the drive motor 1. And sprockets 4 respectively mounted on driven shafts 3 installed in the channel.

As shown in FIG. 2, a rotary brush 18 is disposed on the upper side of the conveyor 10 located outside the waterway, and the scraper 14 handles a large area of lifted material and shakes off a small workpiece or settled sand. A condenser container 5, a conveying screw 6, and a conveyor (not shown) for discharging the contaminants carried out at a natural dropping position according to the brushing operation are installed and a motor 20 for driving them is selectively used.

On the other hand, the present invention detects the water level difference between the water inlet (IP) and the water outlet (OP) into which the sewage and waste water flows, and when the water level is higher than the set water level, the rapid lifting and removing process according to the RPM control of the drive motor 1 is automatically controlled. RPM of the driving motor 1 by the level sensor 22 which is installed at the channel inlet IP and the channel outlet OP, respectively, and detects the level difference, and the output signal according to the level detection of the level sensor 22. The control unit 24 for controlling the is further provided.

Referring to the operation of the device for lifting and removing the contaminants of the present invention, first, each level sensor 22 of the channel inlet IP and the channel outlet OP detects the current level and sets the set water level (position difference Δh). ) Is driven at the set RPM, and if it is higher than that, it means the change of the water level due to the input of a large amount of contaminants. Therefore, the control unit 24 recognizes the output signal of the water level detection to operate the drive motor 1. In this case, the control unit 24 shifts the RPM of the drive motor 1 to the appropriate RPM according to the detected water level.

Subsequently, the conveyor 10 connected by the drive shaft 2, the driven shaft 3, and the sprocket 4 is rotated according to the operation of the drive motor 1, and the contaminants are caught by the respective scrapers 14 to continue to the water phase. When a large area of contaminants lifted from the upper side of the conveyor 10 is handled and sometimes the contaminants are caught in the scraper 14 or soil is blocked by the flow path 16 by the rotary brush 18. The debris caught by the scraper 14 and the brushing motion to shake off the clogged soils in each of the flow path holes 16 are separated by the debris container 5 or the conveying screw 6 and the conveyor (not shown). Is exported. On the other hand, even if the area of the contaminants before the lifting to the water receiving part is large, because the scraper 14 is a fork type, the contaminants are caught by the scraper 14, so the lifting is easy, and the perforated plate due to the separation between the contaminant and the scraper 14 It is rare for a foreign matter to block each flow path hole 16 of the screen 12.

Therefore, generally, the flow of sewage is induced through many flow paths 16, so that the flow path is maintained smoothly, and there is no eddy current caused by the flow path blocking. RPM of the drive motor 1 is caused by the operation of the level sensor 22 and the control unit 24 according to the level change of the channel inlet IP or the channel outlet OP even if the contaminants block the flow path 16. To speed up the lifting process.

As described above, the present invention can efficiently lift and remove irrespective of the area (size) of the contaminants. As the lifting and removing process of the contaminants is automated, selective driving RPM can be adjusted to improve the water treatment capacity and work. By reducing the time, the overall cost savings can be achieved. In addition, efficient removal work can be performed smoothly even if a specific object is excessively introduced, it is to provide the effect of preventing secondary shortcomings, such as flow path blocking and vortex generation.
