It has good elasticity, cold resistance (glass transition temperature -68°C) and high tensile strength. Its resistance to cuts and tears under oxidation resistance and multiple deformation conditions is higher than that of natural rubber.

[0003] According to the Chinese patent publication CN218422774U, a polymerization kettle for producing isoprene rubber includes a box body, a solvent box is fixedly connected to the top of the box body, a mounting block is fixedly connected to the top of the inner wall of the box body, a reaction solvent is put into the solvent box, the reaction solvent can flow into the box body through the discharge port, a card block blocks the discharge port, and can prevent the reaction solvent from flowing into the box body, the rotating plate is rotated to make the slider slide on one side of the rotating plate, and the slider pulls the card block to move, so that the card block is away from the discharge port and cannot block the discharge port. At this time, the reaction solvent flows into the box body through the discharge port, which greatly improves the operation quality and use efficiency compared with the traditional device.

[0004] However, after the polymerization kettle is stirred, some isoprene rubber often remains on the inner wall of the polymerization kettle. Currently, the cleaning is often done manually by staff, but there are often other objects such as heating tubes inside the polymerization kettle, which makes the cleaning work cumbersome and complicated, affecting the production efficiency and product quality of the isoprene rubber. Therefore, designing a new type of polymerization kettle for isoprene rubber production is of great significance for improving cleaning efficiency and ensuring product quality. Summary of the invention

[0005] In order to solve the problem that the current cleaning is often done manually by staff, but there are often other objects such as heating pipes inside the polymerization kettle, which makes the cleaning work cumbersome and complicated, the utility model provides a polymerization kettle for isoprene rubber production to solve the above problem.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A polymerization kettle for producing isoprene rubber comprises a polymerization kettle body, a driving device and a heating tube, wherein the driving device is arranged at the top of the polymerization kettle body, a heating tube is arranged inside the polymerization kettle body, a feed inlet is provided at the top of the polymerization kettle body, a stirring paddle is fixed at the output end of the driving device, a water storage ring is fixed inside the polymerization kettle body, a baffle is fixed at the bottom end of the water storage ring, a water injection port is provided at one end of the outer side of the polymerization kettle body close to the water storage ring, and the water injection port extends to the inside of the water storage ring.

[0008] Furthermore, a discharge port is provided at the bottom end of the polymerization kettle body, and a transmission pipe is fixed at the bottom end of the polymerization kettle body.

[0009] Furthermore, the transmission pipe corresponds to the position of the discharge port, a hot air pipe is fixedly connected to the side of the transmission pipe, and a filter is fixedly provided inside the transmission pipe.

[0010] Furthermore, a fixing block is symmetrically fixed on the outer side of the top of the water storage ring, and a fixing groove matching the shape of the fixing block is opened inside the polymerization kettle body.

[0011] Furthermore, the radius of the outer circle of the baffle is smaller than the radius of the outer circle of the water storage ring, and the side of the baffle close to the polymerization kettle body does not fit the inner wall of the polymerization kettle body.

[0012] Furthermore, a first valve is rotatably connected to the upper part of the transmission pipe, and the first valve is located above the hot air pipe.

[0013] Furthermore, a second valve is rotatably connected to the interior of the transmission pipe, and the second valve is located below the hot air pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, a water storage ring is arranged inside the polymerization kettle body, and a baffle is fixed at the bottom end of the water storage ring, and then a cleaning liquid is input into the water storage ring through the water injection port, so that the cleaning liquid flows out through the gap between the baffle and the inside of the polymerization kettle body, so that the cleaning liquid cleans the inside of the polymerization kettle body, and then the driving device is started to drive the stirring paddle to rotate, so that the stirring paddle stirs the cleaning liquid to perform secondary cleaning on the inner wall of the polymerization kettle body, thereby solving the problem that the current cleaning is often done manually by the staff, but there are often other objects such as heating pipes inside the polymerization kettle, which makes the cleaning work cumbersome and complicated.

[0016] 2. In the utility model, the transmission pipe is connected to the discharge port so that the processed rubber can flow out through the transmission pipe. When the rubber cools and hardens to block the transmission pipe, hot air is blown into the transmission pipe through the hot air pipe to soften the hardened rubber at both ends of the transmission pipe, thereby allowing the rubber to flow out smoothly. This solves the problem that when the rubber cools and hardens, the transmission pipe is blocked, thereby slowing down the speed of the rubber flowing out of the polymerization kettle body.

DETAILED DESCRIPTION

[0023] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A polymerization kettle for producing isoprene rubber, comprising a polymerization kettle body 1, a driving device 2 and a heating tube 3. The driving device 2 is arranged at the top of the polymerization kettle body 1, and the heating tube 3 is arranged inside the polymerization kettle body 1. An inlet 4 is provided at the top of the polymerization kettle body 1, and a stirring paddle 5 is fixed at the output end of the driving device 2. A water storage ring 6 is fixed inside the polymerization kettle body 1, and a baffle 7 is fixed at the bottom of the water storage ring 6. A water injection port 9 is provided at one end of the outer side of the polymerization kettle body 1 close to the water storage ring 6, and the water injection port 9 extends to the inside of the water storage ring 6. A discharge port 15 is provided at the bottom of the polymerization kettle body 1, so that the water storage ring 6 and the stirring paddle 5 clean the inner wall of the polymerization kettle body 1.

[0025] Specifically, a fixing block 8 is symmetrically fixed on the outer side of the top of the water storage ring 6, and a fixing groove that matches the shape of the fixing block 8 is opened inside the polymerization kettle body 1. The radius of the outer circle of the baffle 7 is smaller than the radius of the outer circle of the water storage ring 6. The side of the baffle 7 close to the polymerization kettle body 1 does not fit the inner wall of the polymerization kettle body 1, so that the cleaning liquid can clean the inner wall of the polymerization kettle body 1.

[0026] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a transmission pipe 10 is fixed at the bottom of the polymerization kettle body 1, and the transmission pipe 10 corresponds to the position of the discharge port 15. A hot air pipe 11 is fixed to the side of the transmission pipe 10, and a filter screen 14 is fixed inside to prevent the rubber from being unable to flow out due to cooling.

[0027] Specifically, a first valve 12 is rotatably connected to the upper part of the transmission pipe 10, and the first valve 12 is located above the hot air pipe 11. A second valve 13 is rotatably connected to the lower part of the transmission pipe 10, and the second valve 13 is located below the hot air pipe 11, so that the hot air pipe 11 softens the rubber in two directions respectively.

[0028] Working principle: When the polymerization kettle is finished working, the first valve 12 is opened to release the seal of the first valve 12 on the transmission pipe 10, so that the rubber flows out through the transmission pipe 10. When the rubber inside the polymerization kettle body 1 flows out and cools and hardens, the second valve 13 is closed, and the fan blows hot air into the transmission pipe 10 through the hot air pipe 11, so that the hot air softens the rubber inside the polymerization kettle body 1. When the rubber at the bottom of the transmission pipe 10 cools and hardens, the first valve 12 is closed and the second valve 13 is opened, so that the hot air softens the rubber inside the transmission pipe 10. The rubber at the bottom is softened. When the rubber inside the polymerization kettle body 1 flows out, the water pipe is connected to the water injection port 9, so that the cleaning liquid enters the water storage ring 6 through the water injection port 9, and at the same time flows out through the gap between the baffle 7 and the inner wall of the polymerization kettle body 1, so that the cleaning liquid performs the first cleaning of the inside of the polymerization kettle body 1. At the same time, the driving device 2 drives the stirring paddle 5 to rotate, so that the stirring paddle 5 stirs the cleaning liquid inside the polymerization kettle body 1, so that the cleaning liquid performs the second cleaning of the inside of the polymerization kettle body 1, and the cleaned liquid is discharged through the transmission pipe 10.
