Vacuum spraying box with automatic water level control function

Abstract

The invention belongs to the field of plastic pipe manufacturing, and particularly discloses a vacuum spraying box with an automatic water level control function. The vacuum spraying box comprises a vacuum spraying box body. The inner wall of the bottom end of the vacuum spraying box body is connected with a vertically-arranged partition, a sliding groove is formed in one side of the partition, asliding block is slidingly connected into the sliding groove, the side, away from the sliding groove, of the sliding block is connected with a connecting rod, the side, away from the sliding block, ofthe connecting rod is connected with a float ball valve, the side, away from the connecting rod, of the float ball valve is connected with a sleeve, the interior of the sleeve is connected with a spring, the end of the spring is connected with a mounting plate, the mounting plate stretches out of the sleeve, and a conductive wheel is rotationally connected between the inner walls of the two sidesof the mounting plate. The water level in the vacuum spraying box can be guaranteed, thus, it is guaranteed that the change of the pressure and the stability of cooling water slightly fluctuates, thepercent of pass of production of plastic pipes is increased, a filter plate at the position of a water outlet of the spraying box can be cleaned through the device, blockage of the water outlet is avoided, and the vacuum spraying box is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of plastic pipe manufacturing, in particular to a vacuum spray box for automatically controlling water level. Background technique [0002] In the production process of plastic pipes, the quality and stability of the cooling water in the vacuum spray box may have a great influence on the quality and production efficiency of the pipes. The water level of the cooling water will directly lead to the poor stability of its pressure and flow, and it is easy to cause pits, grooves, roughness on the surface of the pipeline, or jitter rings inside the pipeline, resulting in the unqualified shape of the pipeline. In addition, the cooling water is usually drained directly. In the process of draining, the water outlet pipe is easily blocked due to impurities in the cooling water. Therefore, in order to solve such problems, we propose a vacuum sprayer that automatically controls the water level. Shower box. SUMMARY OF...
