Description
Technical Field
The utility model relates to a buggy balance especially relates to a buggy balance stirring storehouse pressure regulating apparatus.
Background
The stirring bin of the coal powder scale is connected to the bottom of the coal powder bin and is mostly installed in a sealing mode. When the coal powder mixer is used, positive pressure is easily formed in the stirring bin under the influence of the coal feeding fan, the stirring bin is connected with the pulverized coal bin through the plate valve, when more pulverized coal is in the pulverized coal bin, the pressure in the stirring bin cannot be discharged, a swelling bin is formed at the position of the plate valve, the pulverized coal cannot enter the stirring bin or a small amount of pulverized coal cannot enter the stirring bin, and finally the pulverized coal scale is large in fluctuation or cannot be tracked.
To solve this problem, the currently used method:
1. the blowing-assisting device is arranged on the coal powder bin cone, and blows air into the bin to avoid opening the bin or hanging the wall.
2. A bag dust collector is used, and a dust collecting pipeline is arranged on the stirring bin. The method can effectively exhaust the pressure in the stirring bin, but has high installation cost, operation cost and increased danger coefficient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a buggy balance stirring storehouse pressure regulating device can make and effectively obtain the discharge at malleation in the stirring storehouse, solves the stirring storehouse unloading not smooth, the undulant big problem of tracking not up of buggy balance.
The utility model discloses a pulverized coal scale stirring bin pressure regulating device, which comprises a stirring bin, wherein the stirring bin is provided with an observation port flange; the pneumatic plate valve is fixed at the top of the viewing port flange; the first reducing flange is fixed at the top of the pneumatic plate valve; the pressure adjusting mechanism is connected to the top of the first reducing flange; the pressure adjusting mechanism comprises a tee joint, and a first end of the tee joint is fixedly connected with the top of the first reducing flange; the air filter is connected to the second end of the tee joint; and a compressed air source connected with the third end of the tee joint.
Tee bend and air cleaner, tee bend and compressed air source all pass through the pipe connection, are equipped with valve switch on its connecting pipe, and air cleaner can select for use metal filter for use, the used repeatedly of being convenient for.
Preferably, the filter screen cloth is arranged between the pneumatic plate valve and the first reducing flange.
The filter screen cloth can effectively filter the pulverized coal, and the replacement frequency of the air filter is reduced.
Preferably, the pneumatic plate valve further comprises a second reducing flange arranged between the pneumatic plate valve and the observation port flange, and a pressure gauge is installed on the second reducing flange.
The manometer is used for detecting stirring storehouse internal pressure.
The working principle and the using process are as follows: when the pneumatic plate valve is in an open state in an initial state, the valve on the tee joint and a compressed air source connecting pipeline is in a closed state, positive pressure gas in the stirring bin can sequentially pass through the second reducing flange, the pneumatic plate valve, the filter screen cloth, the first reducing flange and the tee joint to be discharged to the air filter element, and specifically, the size of evacuation pressure in the stirring bin can be adjusted through the valve switch arranged on the tee joint and an air filter pipeline; when the valve on the tee joint and the compressed air source connecting pipeline is opened, the filter screen cloth can be reversely blown by compressed air, and the air path is kept smooth. The pneumatic plate valve is used for replacing the filter screen cloth under the condition of ensuring normal driving.
The utility model has the advantages that: the positive pressure in the stirring bin can be effectively discharged, and the problems that the stirring bin is not smooth in discharging and the coal powder scale is not capable of being tracked due to large fluctuation are solved.
