Description

Technical Field

[0001] This utility model mainly relates to the field of sulfonation reaction, specifically to a resin polymerization reactor. Background Technology

[0002] Since its invention, plastic has been ubiquitous in people's lives. It is widely used in numerous industries such as automobiles, aerospace, construction, machinery, and electronics, and its position worldwide is irreplaceable. Generally speaking, the plastic production process includes three parts: resin production, plastic preparation, and plastic product manufacturing. Among these, resin production is a crucial step that determines the quality of plastic. Resin production is the process of linking many small molecule raw materials together through a polymerization reaction to become a high molecular weight compound. The resin polymerization reaction must be carried out in a specific reaction vessel, namely a resin polymerization reactor.

[0003] In the utility model patent application CN202122393635.0, published on January 11, 2022, entitled "A Resin Polymerization Reactor", the reactor includes a vessel body, a stirring shaft, and a drive motor. The stirring shaft is suspended along the centerline of the vessel body, and the drive motor is located below the vessel body. The stirring shaft and the output shaft of the drive motor are connected by a coupling. The coupling and the stirring shaft are connected by screws. A protective cover is provided above the head of the screw to enclose the screw inside the cover. This device supports and fixes the reactor by providing a support base at the lower end of the outer wall of the reactor body, preventing the reactor from tipping over due to vibration during operation and causing danger.

[0004] However, in actual use, because the reactor is a sealed structure, when it is necessary to clean the inside of the reactor, it is necessary to enter the reactor through the manhole, which is quite cumbersome. In addition, the agitator blades need to be replaced according to the type of resin, and replacing the existing internal agitator blades is time-consuming and laborious. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a resin polymerization reactor to solve the problem that, in actual use, due to its overall sealed structure, cleaning the inside of the reactor requires entering through a manhole, which is cumbersome. Furthermore, the agitator blades need to be replaced depending on the type of resin, making the replacement of the internal agitator in existing reactors time-consuming and labor-intensive.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a resin polymerization reactor includes a support frame, a support arm is provided on the upper surface of one side of the support frame, a reactor top cover is fixedly connected to the surface of the support arm, a stirring motor is provided at the top of the reactor top cover, a feed inlet is provided on one side of the stirring motor on the surface of the reactor top cover, a discharge port is provided on one side of the feed inlet, a main reactor body is provided on the lower surface of the reactor top cover, a sealed reactor bottom is provided at the bottom of the main reactor body, and a clamping block is provided below the reactor top cover at the drive end of the stirring motor.

[0009] The sealed vessel bottom includes a bottom cover and an embedded stirring rod. A sealing gasket is provided on the upper surface of the bottom cover. A shaft seat is provided inside the sealing gasket on the surface of the bottom cover. The stirring rod is movably connected to the surface of the shaft seat. A support base is fixedly connected to the surface of the bottom cover. A rotating screw is movably connected to the surface of the support base. A fixing nut is threaded to the top of the rotating screw. A fixing block is fixedly connected to the surface of the main vessel body.

[0010] Furthermore, the fitting clamp and the stirring motor form a transmission structure, and the top surface of the stirring rod is provided with a long strip insert. The stirring rod is connected to the fitting clamp through the long strip insert to form a transmission, so that the stirring rod forms a rotating structure below the top cover of the vessel.

[0011] Furthermore, several of the flipping screws and support seats are provided on the surface of the bottom cover, and the flipping screws form a swing structure on the surface of the support seats. The flipping screws are fixed to the surface of the fixed hanging block by fixing nuts, and the bottom cover is installed on the lower end surface of the main vessel body by the fixed connection between the flipping screws and the fixed hanging block.

[0012] Furthermore, the bottom cover forms a sealed structure at the lower end of the main vessel body through a sealing gasket.

[0013] Furthermore, a cylindrical rotating block is provided at the lower end of the stirring rod, and the stirring rod forms a movable structure on the surface of the insert shaft seat through the cylindrical rotating block.

[0014] 3. Beneficial effects:

[0015] This utility model is reasonably designed. During the resin polymerization reaction, the material is fed through the inlet. The stirring motor is started, which drives the stirring rod to rotate inside the main vessel to stir the resin raw materials. When it is necessary to clean the inside of the main vessel, a hydraulic lifting platform is placed at the bottom of the sealed vessel. After rotating the fixing nut upward, the flipping screw is removed from the fixing block and flipped, so that the bottom of the sealed vessel and the stirring rod fall onto the surface of the hydraulic lifting platform. The hydraulic lifting platform lowers the bottom of the sealed vessel and the stirring rod, which facilitates the cleaning of the bottom of the sealed vessel and the surface of the main vessel. At the same time, the stirring rod is pulled out from the surface of the insert shaft seat and the stirring blade of the required specification is replaced, thus achieving the purpose of convenient replacement of the stirring blade.
