DTRO membrane welding heating mechanism and DTRO membrane welding machine

Abstract

The invention discloses a DTRO (Disk Tubular Reverse Osmosis) diaphragm welding heating mechanism and a DTRO diaphragm welding machine, the welding heating mechanism is mounted on a machine table and comprises a lower die assembly and a lower support plate, the lower support plate can move up and down under the action of a lower die driving part, and the lower support plate is used for bearing a diaphragm to be welded; the upper die assembly comprises a heat conduction upper plate which can move up and down under the action of an upper die driving part so as to be pressed against the diaphragm, and a heat conduction through groove penetrating through the upper end face and the lower end face of the heat conduction upper plate is formed in the heat conduction upper plate; the heating assembly comprises a heating plate capable of moving up and down under the action of a lifting driving assembly, and a shaping heating plate capable of moving in the heat conduction groove and heating the heat conduction groove is arranged at the lower end of the heating plate; the lower end of the shaping heating plate can extend out of the lower end of the heat conduction upper plate along the heat conduction through groove. According to the diaphragm welding device, the diaphragm is reinforced and shaped through mechanical cooperation, the welding quality of the diaphragm is improved, and the finished product quality of the diaphragm is guaranteed.

Description

technical field [0001] The invention relates to the technical field of DTRO diaphragm processing, in particular to a DTRO diaphragm welding heating mechanism and a DTRO diaphragm welding machine. Background technique [0002] DTRO membrane, also known as disc tube reverse osmosis membrane, is a membrane module specially used to treat high-concentration sewage. Its core technology is disc tube diaphragm membrane column, which stacks disc tube diaphragm and hydraulic diversion plate together , fixed with a central tie rod and end plates, and then placed in a pressure-resistant casing to form a membrane column. Among them, the disc tube diaphragm is obtained by welding at least three layers of membrane materials into one and then cutting to ensure high-strength filtration effects such as pressure resistance and corrosion resistance in wastewater treatment. However, the structural design of the existing welding machine is unreasonable, especially the welding heating mechanism, ...

Problems solved by technology

However, the structural design of the existing welding machine is unreasonable, especially the welding heating mechanism, it is difficult to effectively fix the diaphragm, resulting in the peeling phenomenon between the various layers of film materials in later use, which affects the use effect of the film materials
