Description

Technical Field

[0001] This utility model belongs to the field of rubber synthesis and processing technology, and specifically relates to a low-temperature resistant perfluoroether rubber synthesis device. Background Technology

[0002] Low-temperature resistant perfluoroether rubber is a type of high-performance rubber material with excellent chemical resistance, high-temperature resistance, low-temperature resistance, and radiation resistance. It is a perfluoroether-based rubber primarily used in applications requiring operation under extreme conditions, such as aerospace, chemical, and electronics industries. Its processing typically involves synthetic equipment.

[0003] Existing synthesis equipment involves feeding rubber raw materials into a reaction vessel, where a stirring device mixes and reacts the materials to synthesize them. However, during the rubber synthesis process, the viscosity of the raw materials is often high. High-viscosity raw materials have poor flow properties and are not easily driven by the stirrer, resulting in uneven mixing. This not only reduces the efficiency of rubber synthesis but also affects the quality of the synthesized rubber. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature resistant perfluoroether rubber synthesis device that can increase the fluidity of raw materials during stirring by moving the stirring rod up and down, ensuring that all raw materials are effectively stirred, so that the raw materials are heated evenly and the synthesis rate of raw materials is improved.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] The reactor includes a reaction vessel body and a stirring motor. The stirring motor is fixedly installed on the top of the reaction vessel body, and a stirring mechanism is provided inside the reaction vessel body. The stirring mechanism includes a sleeve, an annular groove, a rotating rod, a sliding column, a protrusion, a stirring rod, and a stirring blade. The sleeve is fixedly connected to the top of the inner wall of the reaction vessel body. The annular groove is formed in the inner wall of the sleeve. One end of the rotating rod is fixedly connected to the output end at the bottom of the stirring motor, and the other end of the rotating rod penetrates the interior of the sleeve. The sliding column is sleeved on the surface of the rotating rod and is movably disposed inside the sleeve. The bottom of the sliding column penetrates to the bottom of the sleeve. The protrusion is fixedly connected to the side surface of the sliding column and slidably connected to the interior of the annular groove. The stirring rod is fixedly connected to the bottom of the sliding column, and the stirring blade is fixedly connected to the bottom of the surface of the stirring rod.

[0007] Preferably, a limiting block is fixedly connected to the bottom of the surface of the rotating rod, the limiting groove is vertically opened on the inner wall of the sliding column, and the limiting block is slidably connected to the inside of the limiting groove.

[0008] Preferably, the annular groove is inclinedly formed on the inner wall of the sleeve.

[0009] Preferably, the surface of the stirring rod is fixedly connected with four blades, which are equidistantly connected to the surface of the stirring rod.

[0010] Preferably, the surface of the sheet has holes, and the number of holes is several and they are evenly distributed on the surface of the sheet.

[0011] Preferably, the stirring blade has slots on both sides, and the slots are inclined.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, through the cooperation of the stirring mechanisms, during the mixing and synthesis of raw materials, the stirring motor is first activated. The operation of the stirring motor drives the rotating rod to rotate. The rotation of the rotating rod, through the cooperation of the limiting block and the limiting groove, drives the sliding column and the stirring rod to rotate. When the sliding column rotates, it drives the protrusion to slide along the trajectory of the annular groove. At the same time, under the inclination of the annular groove, the sliding column can move vertically up and down inside the sleeve. When the sliding column moves up and down during rotation, it drives the stirring rod and the stirring blade to move up and down. Thus, by moving up and down while the stirring rod and the stirring blade are rotating, the fluidity of the raw materials during mixing and the mass and heat transfer between materials are increased, ensuring that all raw materials are effectively mixed, the raw materials are heated evenly, and the synthesis rate of the raw materials is improved.

[0014] In this invention, when the stirring rod rotates and moves up and down, it can simultaneously drive the blades to rotate and move up and down. The blades can increase the contact area between the stirring rod and the material, improve the stirring efficiency, and help to form a circulating flow of material, promote the exchange of material between the upper and lower parts, and reduce the dead zones in the stirring. The design of the holes can improve the fluid dynamics performance, reduce turbulence and resistance during the stirring process, and the holes can increase the shear force when the material passes through, which helps to disperse agglomerated particles and improve the mixing effect.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-4 As shown, a low-temperature resistant perfluoroether rubber synthesis device includes a reactor body 1 and a stirring motor 101. The stirring motor 101 is fixedly installed on the top of the reactor body 1, and a stirring mechanism is provided inside the reactor body 1. The stirring mechanism includes a sleeve 201, an annular groove 202, a rotating rod 203, a sliding column 204, a protrusion 205, a stirring rod 206, and a stirring blade 207. The sleeve 201 is fixedly connected to the top of the inner wall of the reactor body 1. The annular groove 202 is formed in the inner wall of the sleeve 201. One end of the rotating rod 203 is fixedly connected to the output end of the bottom of the stirring motor 101, and the other end of the rotating rod 203 passes through the interior of the sleeve 201. The sliding column 204 is sleeved on the rotating rod. On the surface of 203, a sliding column 204 is movably disposed inside the sleeve 201, with the bottom of the sliding column 204 extending through to the bottom of the sleeve 201. A protrusion 205 is fixedly connected to the side surface of the sliding column 204 and slidably connected to the inside of the annular groove 202. A stirring rod 206 is fixedly connected to the bottom of the sliding column 204, and a stirring blade 207 is fixedly connected to the bottom of the surface of the stirring rod 206. Through the coordinated use of the stirring mechanism, the stirring rod 206 and the stirring blade 207 can move up and down while rotating, increasing the fluidity of the raw materials during stirring and the mass and heat transfer between materials, ensuring that all raw materials can be effectively stirred, so that the raw materials are heated evenly and improving the synthesis rate of the raw materials.

[0023] like Figure 4As shown, a limiting block 208 is fixedly connected to the bottom of the surface of the rotating rod 203. A limiting groove 209 is vertically opened on the inner wall of the sliding column 204. The limiting block 208 is slidably connected to the inside of the limiting groove 209. When the rotating rod 203 rotates, it will drive the limiting block 208 to rotate. With the cooperation of the limiting block 208 and the limiting groove 209, the limiting block 208 can engage the sliding column 204 to rotate. During the rotation, with the cooperation of the limiting block 208 and the limiting groove 209, the sliding column 204 can slide vertically up and down on the surface of the rotating rod 203. Thus, the sliding column 204 can not only slide flexibly on the surface of the rotating rod 203, but also be driven to rotate by the rotating rod 203.

[0024] like Figure 2-3 As shown, the annular groove 202 is inclinedly opened on the inner wall of the sleeve 201. Under the action of the inclined annular groove 202, the annular groove 202 can form a height difference. Thus, with the cooperation of the protrusion 205 and the annular groove 202, the sliding column 204 and the stirring rod 206 can be rotated and moved up and down at the same time, which can assist the stirring mechanism to stir more efficiently.

[0025] like Figure 2 As shown, four blades 301 are fixedly connected to the surface of the stirring rod 206. They are equidistantly connected to the surface of the stirring rod 206. The blades 301 help to improve the distribution of materials in the reactor body 1, increase the circulation of materials, promote the exchange of materials between the upper and lower parts, reduce dead zones in the stirring, and improve stirring efficiency.

[0026] like Figure 2 As shown, the surface of the blade 301 has holes 302. There are several holes 302, which are evenly distributed on the surface of the blade 301. The holes 302 can reduce turbulence and resistance during the mixing process, and can increase the shear force when the material passes through, which helps to disperse agglomerated particles and improve the mixing effect.

[0027] like Figure 2 As shown, the stirring blade 207 has slots 4 on both sides. The slots 4 are inclined. The slots 4 on the stirring blade 207 can enhance the shear force of the fluid flow, intensify the shearing and dispersion effect of the material, and form a stronger shear force, which helps to improve the mixing and synthesis efficiency between materials.

[0028] The working principle of this utility model is as follows: When the raw materials are stirred and synthesized, the stirring motor 101 is run first. The stirring motor 101 drives the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the sliding column 204 and the stirring rod 206 to rotate through the cooperation of the limiting block 208 and the limiting groove 209. When the sliding column 204 rotates, it drives the protrusion 205 to slide along the trajectory of the annular groove 202. At the same time, under the inclination of the annular groove 202, the sliding column 204 can move vertically up and down inside the sleeve 201. When the sliding column 204 moves up and down during rotation, it can drive the stirring rod 206 and the stirring blade 207 to move up and down. Thus, by moving up and down while the stirring rod 206 and the stirring blade 207 are rotating, the fluidity of the raw materials during stirring and the mass and heat transfer between materials are increased, ensuring that all raw materials are effectively stirred, so that the raw materials are heated evenly and the synthesis rate of the raw materials is improved.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
