Description

Technical Field

[0001] The invention relates to the technical field of PVC plastisol equipment, in particular to a reaction kettle for producing PVC plastisol. Background Art

[0002] PVC plastisol, also known as polyvinyl chloride coating, is a high-solid, solvent-free coating mixed with a variety of additives. It is mainly composed of polyvinyl chloride powder, plasticizers, fillers, pigments, adhesion promoters and stabilizers, forming a viscous paste with a solid content of more than 95%. When processing PVC plastisol, the reactor is one of the indispensable processing equipment, which can effectively improve the efficiency of PVC plastisol processing.

[0003] For example, the utility model patent disclosed in the publication number CN212942920U is a reactor for the production of polyvinyl chloride film adhesives, including a reactor body, an end cover fixed on the reactor body, a shaft sleeve fixedly embedded on the end cover, a stirring shaft rotating through the shaft sleeve, a mounting seat fixed on the stirring shaft, a motor fixed on the end cover, a mounting block fixed on the rotating shaft of the motor that is slidably inserted and docked with the mounting seat, a scraper fixed on the stirring shaft that contacts the inner wall of the reactor body, which can scrape the adhesive adhering to the inner wall of the reactor body during stirring, a blade fixed on the stirring shaft, and a pointed protrusion fixed on the blade, and a protective sleeve wrapped around the outer wall of the reactor body. The scraper is driven to rotate by the stirring shaft so that it can scrape the adhesive adhering to the inner wall of the reactor body, and the pointed protrusion on the blade can poke and disperse the agglomerated adhesive. At the same time, the stirring shaft and the rotating shaft of the motor are easy to disassemble and can be cleaned regularly.

[0004] Although the above equipment can perform reaction processing operations on raw materials, it is not convenient to adjust the reaction volume of the reactor according to demand, thereby reducing the adaptability of the reactor to subsequent processing of different coatings, and also reducing the practical performance of the reactor. Therefore, a reactor for PVC plastisol production is needed to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a reactor for producing PVC plastisol to solve the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a reactor for producing PVC plastisol, comprising a supporting device for supporting, wherein four corners of the lower end surface of the supporting device are provided with alignment seats for supporting, and the lower end surface of the alignment seats is provided with a fixed roller for guiding, and the middle part of the rear end surface of the fixed roller is provided with a fixed foot brake for limiting.

[0011] Preferably, a circular mixing trough is provided on the inner end surface of the reactor shell, and the sealing guide seat is sealed and slidably connected to the mixing trough, which can facilitate the subsequent up and down displacement of the sealing guide seat in the mixing trough, thereby quickly regulating the volume of the mixture.

[0012] Preferably, the four corners of the inner end surface of the reactor shell are provided with guide grooves for limiting the connecting screw, and the threaded sleeve is slidably engaged inside the reactor shell through the guide grooves. The guide grooves can provide sufficient limiting and guiding space for the subsequent threaded sleeve to slide up and down inside the reactor shell, thereby improving the stability of subsequent height control of the sealing guide seat.

[0013] Preferably, the four groups of driven gears located on the side are all meshedly connected with the driving gear, and the inner end surface of the reactor shell is hollow, which can effectively reduce the mixing noise inside the equipment.

[0014] Preferably, the transmission gear located in the middle is meshedly connected with the four groups of transmission gears located on the sides, and the mixing blades and the transmission clamping shaft do not contact the inner wall of the reactor shell, which can prevent limitation during subsequent high-speed mixing and improve the stability of subsequent transmission.

[0015] Preferably, the sealing guide seat is adapted to the connecting screw through the threaded sleeve and is then sealingly and slidably connected to the inside of the reactor shell. The threaded connection of four groups of connecting screws and the threaded sleeve can improve the accuracy of the subsequent connecting screw driving the sealing guide seat to move up and down inside the reactor shell.

[0037] The inner end surface of the reactor shell 41 is provided with a circular mixing groove, and the sealing guide seat 514 is sealed and slidably connected to the mixing groove, which can facilitate the subsequent upward and downward displacement of the sealing guide seat 514 in the mixing groove, thereby quickly adjusting the volume of the mixture.
