A pipe fixing device with replaceable filter plate based on the principle of air sealing

Abstract

A pipe fixing device for a replaceable filter plate based on the principle of air sealing, which relates to the field of sewage technology, and includes a connecting pipe. The inner wall of the connecting pipe is provided with two mutually symmetrical air chambers one, the inner side of the air chamber one is close to the connecting pipe The middle part of the pipe is fixedly connected with a rubber ring, and the inner wall of the middle part of the connecting pipe is provided with mutually symmetrical locking grooves. The pipeline fixing device of the replaceable filter plate based on the principle of air sealing is used through the cooperation of the air cavity one and the rubber ring. Inflates, and the rubber ring squeezes the piston block to the middle of the movable tube, the piston block squeezes the gas in the air cavity two, accelerates the movement of the internal gas molecules, increases the temperature inside the air cavity, and makes the fluorescent block heated and glows, thus It achieves the effect of prompting the sealing result, effectively guarantees the tightness of the seal, ensures the transportation of the pipeline, effectively prevents leakage, and improves the sealing effect.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a pipe fixing device for a replaceable filter plate based on the principle of air sealing. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is referred to as sewage for short. It is mainly water after daily use. It contains a lot of organic matter and is not easy to treat. The sewage is mainly discharged through sewage pipes. Due to the long distance of transportation, the pipes cannot be The one-piece type can only be composed of multiple sections of pipelines. At this time, a pipeline connection device is required to connect the adjacent pipelines at both ends. [0003] Most of the current pipe connection devices are sealed by sealing gaskets. This sealing method is relatively simple, and the sealing effect cannot be observed in time. The sealing effect ...

AI Technical Summary

Problems solved by technology

[0003] Most of the current pipe connection devices are sealed by sealing gaskets. This sealing method is relatively simple, and the sealing effect cannot be observed in time. The sealing effect can only be known after water flows, but if there is water leakage at this time, it is too late. It is too late, the pipeline needs to be dug up and re-sealed, and the workload of rework is even greater, affecting the progress of the entire pipeline laying, and now most of the filter plates are fixed in the pipeline, when the filter plate is used for a long time and needs to be replaced , it is difficult to replace, which increases the difficulty of replacing the filter plate, and can only replace the entire pipeline, which increases the cost and has low practicability
