Description

Technical Field

[0001] The present invention relates to the technical field of chlorination, and particularly to an automatic exhaust device for a chlorination pipeline. Background Art

[0002] In the process of water treatment, chlorination is a common disinfection method.

[0003] However, in the prior art, gas accumulation often occurs in the chlorination pipeline, resulting in unstable pipeline pressure and unnecessary loss of chlorine. During the use of the chlorination pipeline, due to various reasons, gas will be mixed into the pipeline. If these gases are not discharged in time, it will affect the chlorination effect and stability, and may even cause problems such as pipeline blockage.

[0004] Currently, the method of manual exhaust is usually adopted. This method is not only inefficient, but also inconvenient to operate and has certain safety risks. Some automatic air exhaust devices have appeared on the market, but most of them have complex structures, high costs and difficult maintenance, and are difficult to be widely popularized. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic exhaust device for a chlorination pipeline to solve the problems raised in the above background art.

[0007] A medicine outlet pipeline and a return pipeline connected to the lower side of the side wall of the medicine storage tank;

[0008] Wherein, a safety pipeline is connected to the pipeline of the medicine outlet pipeline, the other end of the safety pipeline is connected to the return pipeline, and the end of the return pipeline far from the medicine storage tank is connected to the medicine outlet pipeline;

[0009] An exhaust assembly is installed on the pipeline of the return pipeline, a safety valve is installed on the pipeline of the safety pipeline, a medicine adding pump is arranged on the pipeline of the medicine outlet pipeline, and a back pressure valve is arranged on the pipeline of the medicine outlet pipeline far from the medicine storage tank.

[0010] Preferably, a medicine adding port is arranged on the top of the medicine storage tank, and a cover is arranged on the medicine adding port.

[0011] Preferably, a Y-type filter is arranged on the pipeline of the medicine outlet pipeline.

[0012] Preferably, a vent pipe is connected to the pipeline of the medicine outlet pipeline, the vent pipe is located upstream of the back pressure valve, and a pressure gauge and a manual vent valve are arranged on the pipeline of the vent pipe.

[0013] Preferably, the exhaust assembly includes a connecting pipe arranged on the pipeline of the reflux pipe. An exhaust pipe is arranged above the connecting pipe. An exhaust hole communicating with the exhaust pipe is formed on the upper surface of the connecting pipe. An active closing assembly is arranged in the exhaust pipe, and the position of the active closing assembly corresponds to that of the exhaust hole.

[0014] Preferably, the active closing assembly includes a lower plug, a spring connected to the upper surface of the lower plug, and a floating ball connected to the top of the spring. The position of the lower plug corresponds to that of the exhaust hole. The diameters of the lower plug and the floating ball are smaller than the diameter of the exhaust pipe, and the diameter of the lower plug is larger than the diameter of the exhaust hole.

[0015] Preferably, an anti-dropping mesh is arranged at the inner top end of the exhaust pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The device automatically detects the gas pressure in the pipeline and automatically exhausts the gas, effectively solving the problems of low efficiency and great potential safety hazards of the traditional manual exhaust method. The device has a simple structure, low cost, and is easy to maintain. It can be widely applied to various containers and pipeline systems to ensure the normal operation of the system. It reduces the manual opening of the exhaust valve by personnel, solves the chlorine problem generated in actual drug addition, and reduces the situation that the dosing pump has no flow and cannot dose or the dosing amount is unstable caused by chlorine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
