Description
Technical Field
The invention belongs to the technical field of pollution discharge, and particularly relates to a siphon type pollution discharge device with a pneumatic power assisting function, an electrical device and a control method for electrifying and stopping a flow of a displacement pump, which are used for a sewage treatment system of a raw material workshop of a building ceramic factory.
Background
The sewage discharge pipe is extremely important in daily life and production activity management of people and is used for discharging garbage in production and life. Particularly, for a sewage treatment system of a building ceramic factory, a large amount of sewage and sludge are generally included, the sludge generally has certain thixotropy after being subjected to medicament treatment processes such as sedimentation, deflocculation and the like, and is very easy to deposit on a pipeline or a turning dead angle position and gradually block the pipeline due to lack of continuous power after a main sewage discharge motor is stopped, so that the next sewage discharge function is failed. In order to prevent the pipeline from being blocked, a bend is usually arranged on the pipeline below the sewage disposal pool, an openable cover is arranged at the bend of the pipe body, the bend of the pipe body is helpful for retaining larger garbage, sewage or sludge, and then the bend of the pipe body is cleaned regularly. However, this method is cumbersome and difficult to operate, and sometimes the waste or sludge accumulated in the bent portion of the pipe body can be discharged by slightly stirring it. The siphon is an ancient invention for human beings, and a peculiar siphon is produced by people in the first century before the public yuan. For example, a water tank is filled with water, one end of a pipe is placed in the water, the other end of the pipe naturally hangs down along the tank, the mouth of the pipe is used for sucking air for a while, and then the mouth of the pipe is released, so that the water in the tank flows down from the pipe.
CN201520577402.8 discloses a pneumatic power-assisted blow off pipe, its purpose provides a kind of pneumatic power-assisted blow off pipe, and this pneumatic power-assisted blow off pipe device has the characteristics that can stir and the breakage utilize pneumatic power-assisted propelling movement rubbish simultaneously to the rubbish of body kink department. The pneumatic power-assisted blow-off pipe comprises a blow-off pipe body, wherein the blow-off pipe body is provided with a bend, an impeller capable of freely rotating is arranged on the inner wall of the blow-off pipe body below the bend of the blow-off pipe body, blades of the impeller are provided with sharp edges, and a hole is formed in the pipe wall below the impeller and communicated with an air outlet nozzle of a compressed air bottle. The working principle is as follows: when the rubbish flows into the bending part of the pipe body, the fluid impacts the impeller, the impeller stirs the rubbish, and sharp edges of blades on the impeller are beneficial to cutting up the rubbish, so that the rubbish is discharged. Open compressed air bottle air outlet nozzle control valve, the air admission blow off pipe helps strengthening the stirring and the discharge of rubbish, with rubbish propelling movement forward, the gas that rises simultaneously helps the rotation of drive blade, stirs the cutting to rubbish better. The garbage can has the disadvantages that the garbage can is beneficial to enhancing the stirring and discharging of the garbage and pushing the garbage forwards. But the problem of deposition at the position of a pipeline or a bent dead angle after a long-distance transportation machine is stopped cannot be solved well all the time.
