Polyester resin powder spraying type heat treatment device

Abstract

The invention discloses a polyester resin powder spraying type heat treatment device which comprises a box body, a driving mechanism, a heating tank and a collecting box, and a cover plate covers theupper end surface of the box body; the driving mechanism is arranged in the cover plate, containing grooves which are symmetrically formed about the driving mechanism are formed in the upper surface of the cover plate, the bottoms of the containing grooves communicate with spray heads through pipelines, and the spray heads are located in the heating tank; the heating tank is fixedly connected to the inner side wall of the box body through an annular fixing plate, and an annular scraping plate is slidably connected into the heating tank; Polyester resin powder can be subjected to heat treatment, the melting speed of the polyester resin powder is increased, the melting effect of the polyester resin powder is guaranteed, damage of high temperature to the structure in the polyester resin powder is avoided, meanwhile, the residual amount of a polyester resin powder solution on the inner wall of the heating tank can be reduced, and resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of polyester resin powder processing equipment, in particular to a polyester resin powder spraying heat treatment device. Background technique [0002] Ester resin is the abbreviation of unsaturated polyester adhesive. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, initiators, accelerators, fillers, thixotropic agents, etc.; mainly used in the production of coil coatings; polyester resins are composed of diols or dibasic acids or polyols and polybasic A general term for polymer compounds formed by polycondensation of acids. Polyester resin is divided into saturated polyester resin and unsaturated polyester resin. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments and fillers, initiators and other additives. [0003] At present, the polyester resin powder heat treatment device generally directly puts a large amount of polyeste...

Problems solved by technology

[0003] At present, the polyester resin powder heat treatment device generally directly puts a large amount of polyester resin powder in a heating tank for heating and dissolving. If the temperature is too high, it will destroy the structure of the polyester resin powder. If the temperature is too low, it will make The polyester resin powder away from the heating tank wall is difficult to dissolve, which affects the dissolution effect of the polyester resin powder. At the same time, after the dissolved polyester resin powder is discharged, a large amount of polyester resin powder solution will adhere to the inner wall of the heating tank, not only It causes a waste of some resources, and also increases the difficulty of cleaning the inner wall of the heating tank, which brings convenience to the staff
