Description

Technical Field

[0001] This utility model relates to the field of paste filling technology, specifically to a paste filling pipeline cleaning system. Background Technology

[0002] The utility model patent with application number CN202121725949.X—a device for high-efficiency flushing pipelines—includes a water storage tank, a first transmission pipe, a filling pump, a second transmission pipe, a regulating gate valve, a first one-way distribution valve, a third transmission pipe, a safety valve, a second one-way distribution valve, a fourth transmission pipe, and a slurry discharge tank. The first transmission pipe is inserted into the upper part of the water storage tank. The regulating gate valve is connected to the left side of the inside of the first transmission pipe, and the first one-way distribution valve is connected to the lower left end of the first transmission pipe. Utilizing the ground-based water storage tank with a capacity of approximately 900 cubic meters, it can meet the flushing volume for one cycle. Furthermore, it uses raw water for flushing, eliminating the need for sewage treatment. Water treatment costs 2.4 yuan per cubic meter. Depending on the pipeline length, the flushing volume is generally 3 to 4 times the pipeline capacity. Typically, one cycle requires approximately 400 cubic meters of flushing water, saving on sewage treatment costs. The use of non-powered flushing reduces equipment wear, making it more economical, energy-efficient, and highly effective.

[0003] Because of the more than 200-meter drop between the well and the surface, the water in the pipe forms a siphon effect due to its own gravity, which cleans the filling pipeline. However, water slurry is easily left in the straight section of the pipeline, which can easily corrode the pipeline. Moreover, after the water slurry solidifies, it adheres to the pipe wall, which will affect the quality of subsequent paste filling and the service life of the pipeline. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a paste filling pipeline cleaning system. The technical problem it solves is that water slurry easily remains inside the filling pipeline, affecting the quality of subsequent paste filling and the service life of the pipeline. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A paste-filled pipeline cleaning system, comprising: The system consists of a water injection mechanism, a first pipeline, a pigging valve, and a filling pipeline. The water injection mechanism is connected to one valve port of the pigging valve through the first pipeline, and the other two valve ports of the pigging valve are connected to the filling pipeline. The first valve is installed on the first pipeline; The mounting hole is located on the side wall of the first pipeline between the first valve and the pigging valve. A sealing cap is used to seal the installation hole, and the sealing cap is connected to the first pipeline by an opening and closing mechanism; The fan and the second pipeline are connected to the first pipeline through the second pipeline, and the connection between the second pipeline and the first pipeline is located between the first valve and the mounting hole. The second valve is installed on the second pipeline; It is also equipped with a cleaning ball for cleaning the filling pipeline.

[0005] The water injection mechanism includes a water tank, an inlet pipe, and a water pump. The water tank is connected to the water pump inlet through the inlet pipe, and the water pump outlet is connected to the first pipeline.

[0006] The water pump is a high-pressure water pump.

[0007] Both the first and second valves are electric valves.

[0009] An installation tube is provided on the side wall of the first pipeline around the installation hole, and the installation tube is connected to the sealing cap by a hinge structure. The mounting tube is equipped with a locking mechanism for locking the sealing cap.

[0011] The nut is a wing nut.

[0012] A sealing ring is fixedly installed on the inner end face of the sealing cover.

[0013] A handle is fixedly installed on the outer end face of the sealing cover.

[0014] The beneficial effects of this utility model are as follows: After the water injection cleaning is completed, the sealing cover is opened, the cleaning ball is placed into the first pipeline, the blower is started, and the compressed air generated by the blower pushes the cleaning ball to move in the filling pipeline, scraping away the residual water slurry in the pipeline, improving cleaning efficiency, reducing the corrosion of the pump pipe by the water slurry, and also reducing the adhesion of the water slurry after solidification, improving service life and the smoothness of subsequent paste filling.
