Operating cost height be restrict active coke desulphurizing technology large-scale promotion application technical bottleneck, activated coke high cost,
In running, waste is greatly the principal element for causing the technical operation cost to increase, and mechanical loss accounts for active coke desulphurizing work
More than the 60% of skill loss.What mechanical loss was produced is primarily due to activated coke Jing discharge valves, chain bucket in circulation technology
Machine is transported and produces breakage, therefore by optimizing the structure of discharge valve, bucket machine, the mechanical loss for reducing activated coke is to solve to live
Property burnt desulfurization technical operation high cost one of approach.
In active coke desulphurizing adsorption tower and Analytic Tower, activated coke relies on gravity and from up to down moves, and conciliates in absorption
During analysis, it is required at any time according to Load Regulation activated coke circulating load, is measured using weighing pattern under normal circumstances, but
System can be made to become increasingly complex, adjust inconvenient.If a kind of discharge valve with function of measuring of exploitation will make whole work
Skill is greatly simplified.
Based on problem above, a kind of activated coke discharge valve with function of measuring is developed, while solving the abrasion of activated coke
Problem, it is significant for the application and popularization of active coke desulphurizing technology.
The content of the invention
In order to solve the problems, such as above-mentioned prior art, it is an object of the invention to provide a kind of with function of measuring
Centering type activated coke star-shaped discharge valve, is capable of achieving the equal control of activated coke continuous discharge and activated coke discharging quantity, it is possible to
The breakage rate of activated coke is reduced, discharge valve power of motor is reduced.
To reach object above, the present invention is adopted the following technical scheme that：
A kind of centering type activated coke star-shaped discharge valve with function of measuring, including material inlet 1, material inlet 1 and star-like rotation
Rotary valve 4 is arranged using centering type, middle to be connected by inclining material road 3, and curved surface bucket 5, bottom are placed equidistant inside star-like rotary valve 4
Portion is connected with discharging opening 6, and electric rotating machine 8 is connected with star-like rotary valve 4 by driving belt 9.
The angle between horizontal plane for inclining material road 3 is 35 °, more than activated coke angle of repose.
The electric rotating machine 8 is arranged in gripper shoe 7, and gripper shoe 7 is directly welded in material inlet 1, inclines material road 3, star-like
On the valve body that rotary valve 4 and discharging opening 6 are formed.
The blade quantity of the curved surface page 5 is 4～12, the fit clearance of curved surface bucket 5 and 4 housing of star-like rotary valve
For 2～5mm.
The electric rotating machine 8 adopts VFC motor.
3 top of the inclination material road arranges maintenance hand hole 2.
Compared to the prior art the present invention, has the advantage that：
1st, the present invention is equidistantly positioned curved surface bucket, and interlobate distance is identical with space, often rotate a blade away from
From, activated coke discharging quantity is essentially identical, therefore by controlling discharge valve rotary speed, it is possible to realize to activated coke discharging quantity
Metering.
2nd, activated coke adsorb and Analytic Tower in, activated coke is from up to down moved by gravity, bottom activated coke bear compared with
Big pressure, discharge valve material inlet of the present invention are arranged using centering type with discharge valve, are so greatly lowered discharge valve and rotate resistance
Power and the shearing force to activated coke, reduce motor load and activated coke breakage rate.
3rd, the present invention adopts curved surface bucket, and the gap between blade and discharging valve chest is 2～5mm, less than active char particle
Footpath, does not result in activated coke extruding breakage between blade and housing, reduces activated coke loss and motor power consumption.
4th, the present invention inclines material road angle of inclination and is more than 35 °, slightly using material road connection material inlet and rotary discharge valve is inclined
More than activated coke stocking angle, it is ensured that the fluency of discharging.
5th, this valve body motor and valve body are an entirety, are easily installed and overhaul.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in figure 1, a kind of centering type activated coke star-shaped discharge valve with function of measuring of the present invention, including material inlet 1,
Material inlet 1 is arranged using centering type with star-like rotary valve 4, middle to be connected by inclining material road 3, equidistant inside star-like rotary valve 4
Curved surface bucket 5 is set, and bottom is connected with discharging opening 6, and electric rotating machine 8 is connected with star-like rotary valve 4 by driving belt 9.
Used as the preferred embodiment of the present invention, the angle between horizontal plane of the inclination material road 3 is 35 °, more than work
Property burnt angle of repose.
Used as the preferred embodiment of the present invention, the electric rotating machine 8 is arranged in gripper shoe 7, and gripper shoe 7 is directly welded
