Solar water heater water storage tank foaming production line

Abstract

The present invention discloses a solar water heater water storage tank foaming production line, which comprises an inflation device, wherein the inflation device comprises a plurality of gas storage tanks, a main gas pipe, a plurality of branch gas pipes, and a plurality of one-way safety valves, the branch gas pipes are corresponding to the one-way safety valves one to one, the gas storage tank is installed on a tooling trolley and collectively flows along with a foaming production line, various gas storage tanks are communicated in series through the main gas pipe, the main gas pipe is provided with the plurality of the branch gas pipes, the branch gas pipes are communicated with water storage tanks through the respective one-way safety valves, and provided for inflating the water storage tanks, and the one-way safety valves are provided for controlling water storage tank inflation. According to the present invention, the plurality of the gas storage tanks are arranged on the foaming production line, and are communicated in series through the main gas pipe, the main gas pipe is provided with the plurality of the branch gas pipes communicated with the water storage tanks through the one-way safety valves for inflation, such that it is ensured that pressure and other conditions inside various branch gas pipes are the same, uniformity of various water storage tanks after inflation is good, and the one-way valve can prevent the liner from breakage caused by excessive inflation so as to ensure foaming quality of polyurethane.

Description

technical field [0001] The invention relates to the field of water heater processing, in particular to a foaming production line for a solar water heater storage tank. Background technique [0002] The water storage tanks for solar water heaters all include an inner tank and an outer shell. At present, the pressurized and open solar water heater water storage tanks are filled with polyurethane foam. The process is as follows: a certain gas is filled in the inner tank to make it expand properly, and then the insulation material polyurethane is poured into the interlayer between the outer shell and the inner tank and Let it foam. At present, a circular push-type foaming production line is usually used, and the production line includes: assembly area, preheating area, material injection area, aging area and disassembly area from the beginning to the end. The water storage tanks to be processed in production pass through each processing area in turn to complete the production ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of the existing technology that the continuous flow operation cannot be performed, the effect of the water storage tank can not be guaranteed after inflation, and the consistency is poor, the embodiment of the present invention provides a solar water heater water storage tank foaming production line
