Mixing device for processing saturated polyester resin

Abstract

The mixing device for saturated polyester resin processing comprises a shell, an end cover, a driving device, a mixing cylinder, a scraper blade, a stirring rod and a rotating shaft; supporting columns are arranged at the bottom of the shell; the mixing cylinder extends into the shell from an opening in the upper end of the shell and presses the bottom of the shell; a groove for pressing the mixing cylinder is formed in the end face of the end cover; the end cover is located on the upper end face of the shell and faces the end face of the shell to press the upper end face of the shell; the outer peripheral surface of the mixing cylinder, the inner wall of the shell and the end cover form a heating bin for mounting a heater; the rotating shaft penetrates through the end cover, extends intothe mixing cylinder, is rotationally connected with the end cover and is in transmission connection with the driving device; the rotating shaft is provided with a plurality of groups of stirring plates on the peripheral surface of the mixing cylinder; shunting holes are uniformly formed in the end surfaces of the plurality of groups of stirring plates and are connected with the plurality of groupsof scrapers; the plurality of groups of scrapers are attached to the inner wall of the mixing cylinder; the plurality of groups of stirring rods are positioned below the plurality of groups of stirring plates and are arranged on the rotating shaft. According to the invention, saturated polyester resin production raw materials can be rapidly, efficiently and uniformly mixed.

Description

technical field [0001] The invention relates to the technical field of saturated polyester resin processing, in particular to a mixing device for processing saturated polyester resin. Background technique [0002] The most commonly used saturated polyester resin in the coatings industry is a polyester resin containing terminal hydroxyl functional groups, which is cured by cross-linking with isocyanate, amino resin and other resins to form a film. Different raw materials make different contributions to the performance of the resin. When selecting raw materials, the performance requirements of the resin should be considered, and the corresponding raw materials that can help the required performance of the resin should be selected from the aspects of functionality, hardness, flexibility, etc. Consider; in the production and processing of saturated polyester resin, it is necessary to mix the raw materials of saturated polyester resin evenly, but the efficiency of mixing and stir...

Problems solved by technology

Different raw materials make different contributions to the performance of the resin. When selecting raw materials, the performance requirements of the resin should be considered, and the corresponding raw materials that can help the required performance of the resin should be selected from the aspects of functionality, hardness, flexibility, etc. Consider; in the production and processing of saturated polyester resin, it is necessary to mix the raw materials of saturated polyester resin evenly, but the efficiency of mixing and stirring of the existing mixing equipment is low, and the raw material of saturated polyester resin is easy to adhere to the cylinder wall, Cause waste of raw materials, in addition, the existing mixing cylinder is inconvenient to disassemble to clean the inside of the mixing cylinder; therefore, this application proposes a mixing device for processing saturated polyester resin
