Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor technology, and in particular to a vinyl-modified organosilicon resin reactor. Background Technology
[0002] Vinyl-modified silicone resin is a silicone polymer material with silicon-oxygen bonds (Si-O bonds) as the main chain and vinyl side chains. This structure endows it with unique properties, such as resistance to high and low temperatures, chemical corrosion resistance, and electrical insulation properties. Reactive gases are introduced into the reactor as a source of active species to participate in the reaction process. In existing technologies, the inlet pipe uses a valve to control the input gas. However, a portion of the inlet pipe extends into the reactor, allowing material to flow back into the inlet pipe, causing blockage. Furthermore, the gas output from the inlet pipe is unidirectional, resulting in poor diffusion and low contact between the reactive gas and the material, leading to a low degree of reaction as the reactive gas rises. Utility Model Content
[0003] The technical problem to be solved by this utility model is: in order to overcome the problems in the prior art where a part of the inlet pipe extends into the reactor, causing material to flow back into the inlet pipe and causing blockage, and the gas output from the inlet pipe is unidirectional, resulting in poor diffusion of the output gas and low contact between the reaction gas and the material, a vinyl-modified organosilicon resin reactor is provided.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a vinyl-modified organosilicon resin reactor, including a reaction shell and a stirring assembly arranged in the reaction shell;
[0005] The reaction shell has a accommodating cavity, a material inlet communicating with the accommodating cavity is opened on the top surface of the reaction shell, a material outlet communicating with the accommodating cavity is opened on the bottom surface of the reaction shell, a reaction gas inlet pipe communicating with the accommodating cavity is opened on the lower side of the reaction shell, and a reaction gas outlet pipe communicating with the accommodating cavity is opened on the upper side of the reaction shell.
[0006] The output end of the reaction gas inlet pipe is bent downwards to form a guide section. A backflow prevention and diffusion mechanism is arranged within the guide section. The backflow prevention and diffusion mechanism is used to prevent the reaction gas inside the reaction shell from flowing back into the reaction gas inlet pipe and to assist the diffusion of the reaction gas input into the reaction gas inlet pipe. Through the design of the backflow prevention and diffusion mechanism, on the one hand, it can block the reaction gas inlet pipe when there is no gas supply, preventing the material from flowing back into the reaction gas inlet pipe and blocking it; on the other hand, it can make the input reaction gas diffuse circumferentially, increasing the contact between the reaction gas and the material, thereby improving the degree of reaction and avoiding waste.
[0007] The mechanism further includes a backflow prevention and diffusion mechanism comprising a movable seat, a slider, a first elastic element, and a second elastic element.
[0008] The slider and guide section are radially fixed, and a first flow hole is provided on the slider;
[0009] The movable seat and the slider are fixedly connected. One end of the first elastic element is connected to the slider, and the other end is connected to the guide section. In the initial state, the elastic force of the first elastic element makes the bottom surface of the movable seat and the port of the guide section flush.
[0010] The movable seat has a flow cavity, and a second flow hole communicating with the flow cavity is opened on the top surface of the movable seat. The second flow hole is connected with the first flow hole. Several third flow holes are spaced apart on the side of the movable seat. The third flow holes are connected with the flow cavity. A sealing plate is arranged in the third flow hole. The top surface of the sealing plate is rotatably connected to the movable seat.
[0011] The second elastic element is located in the flow cavity. One end of the second elastic element is connected to the lower part of the sealing plate, and the other end is connected to the movable seat. In the initial state, the elastic force of the second elastic element causes the sealing plate to remain in the third flow hole.
[0012] To address the issue of poor stability of the second elastic element, the system further includes a connecting rod located within the flow cavity inside the movable seat. One end of the second elastic element is connected to the lower part of the sealing plate, and the other end is connected to the connecting rod of the movable seat.
[0013] To address the issue of poor stability of the second elastic element, the circulation cavity of the movable seat further includes a traction telescopic component. One end of the traction telescopic component is rotatably connected to the sealing plate, and the other end is rotatably connected to the connecting rod. The second elastic element is sleeved on the traction telescopic component.
[0014] To address the issue of poor diffusivity of the reactant gas after circumferential diffusion, a backflow prevention diffusion mechanism is further included, comprising an impeller and a slider fixedly connected, with the impeller positioned above the slider.
[0015] To address the issue of insufficient contact between the reactant gas and the material, the reaction gas inlet pipe and the reaction gas outlet pipe are further spaced 120°-180° apart along the circumference of the reaction shell.
[0016] The beneficial effects of this utility model are as follows: This utility model provides a vinyl-modified organosilicon resin reactor. Through the design of the anti-reverse diffusion mechanism, on the one hand, it can block the reaction gas inlet pipe when no gas is supplied, preventing the material from flowing back into the reaction gas inlet pipe and blocking it; on the other hand, it can make the input reaction gas diffuse circumferentially, increasing the contact between the reaction gas and the material, thereby improving the degree of reaction and avoiding waste.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] like Figure 1 This is a schematic diagram of the structure of the present invention, a vinyl-modified organosilicon resin reactor, including a reaction shell 1 and a stirring assembly 2 arranged inside the reaction shell 1;
[0024] The reaction shell 1 has a accommodating cavity 11, a material inlet 12 communicating with the accommodating cavity 11 is opened on the top surface of the reaction shell 1, a material outlet 13 communicating with the accommodating cavity 11 is opened on the bottom surface of the reaction shell 1, a reaction gas inlet pipe 14 communicating with the accommodating cavity 11 is provided on the lower side of the reaction shell 1, and a reaction gas outlet pipe 15 communicating with the accommodating cavity 11 is provided on the upper side of the reaction shell 1.
[0025] The output end of the reaction gas inlet pipe 14 is bent downward to form a guide section 141. The reaction gas inlet pipe 14 has an L-shaped structure. A backflow prevention and diffusion mechanism 3 is arranged in the guide section 141. The backflow prevention and diffusion mechanism 3 is used to prevent the reaction gas in the reaction shell 1 from flowing back into the reaction gas inlet pipe 14 and to assist the diffusion of the reaction gas input into the reaction gas inlet pipe 14.
[0026] like Figure 2As shown, the anti-reverse diffusion mechanism 3 includes a movable seat 31, a slider 32, a first elastic element 33, and a second elastic element 34.
[0027] The slider 32 and the guide section 141 are radially fixed, that is, the slider 32 and the guide section 141 are slidably connected. The slider 32 can move along the axial direction of the guide section 141, and the slider 32 and the guide section 141 are rotatably connected. The slider 32 can rotate circumferentially. A first flow hole 321 is provided on the slider 32 so that the reaction gas can pass through.
[0028] The movable seat 31 and the slider 32 are fixedly connected. Similarly, the movable seat 31 can move axially along the guide section 141, and the movable seat 31 and the guide section 141 are rotatably connected. The movable seat 31 can rotate circumferentially. One end of the first elastic element 33 is connected to the slider 32, and the other end is connected to the guide section 141. The first elastic element 33 is a spring. In the initial state, the elastic force of the first elastic element 33 makes the bottom surface of the movable seat 31 flush with the end of the guide section 141.
[0029] like Figure 2 As shown, the movable seat 31 has a flow cavity 311. A second flow hole 312 communicating with the flow cavity 311 is opened on the top surface of the movable seat 31. The second flow hole 312 is connected with the first flow hole 321. A plurality of third flow holes 313 are spaced apart on the side of the movable seat 31. There is one or more third flow holes 313. The third flow holes 313 are connected with the flow cavity 311. The second flow hole 312, the third flow holes 313 and the flow cavity 311 allow the reaction gas to pass through. A sealing plate 314 is arranged in the third flow hole 313. The top surface of the sealing plate 314 is rotatably connected to the movable seat 31.
[0030] like Figure 2 As shown, the second elastic element 34 is located in the flow cavity 311. One end of the second elastic element 34 is connected to the lower part of the sealing plate 314, and the other end is connected to the movable seat 31. The second elastic element 34 is a spring. The elastic coefficient of the second elastic element 34 is greater than the elastic coefficient of the first elastic element 33. In the initial state, the elastic force of the second elastic element 34 causes the sealing plate 314 to stay in the third flow hole 313.
[0031] like Figure 2 As shown, the movable seat 31 has a connecting rod 315 located in the flow cavity 311. One end of the second elastic element 34 is connected to the lower part of the sealing plate 314, and the other end is connected to the connecting rod 315 of the movable seat 31.
[0032] like Figure 2As shown, the movable seat 31 also has a traction telescopic member 316 in the flow cavity 311. One end of the traction telescopic member 316 is rotatably connected to the sealing plate 314, and the other end is rotatably connected to the connecting rod 315. The second elastic element 34 is sleeved on the traction telescopic member 316. The traction telescopic member 316 is a telescopic rod, and the traction telescopic member 316 provides support for the second elastic element 34.
[0033] like Figure 2 As shown, the anti-reverse diffusion mechanism 3 includes an impeller 35, which is fixedly connected to a slider 32. The impeller 35 is located above the slider 32. The impeller 35 can rotate under the flow of the reaction gas and drive the movable seat 31 to rotate.
[0034] like Figure 1 As shown, the reaction gas inlet pipe 14 and the reaction gas outlet pipe 15 are spaced 120°-180° apart along the circumference of the reaction shell 1, which increases the flow of reaction gas in the reaction shell 1, thereby increasing the residence time and improving the utilization rate of reaction gas. Preferably, the reaction gas inlet pipe 14 and the reaction gas outlet pipe 15 are spaced 180° apart along the circumference of the reaction shell 1.
[0035] In the initial state, that is, no reactive gas is introduced into the reactive gas inlet pipe 14, the elastic force of the first elastic element 33 makes the bottom surface of the movable seat 31 flush with the port of the guide section 141, and the elastic force of the second elastic element 34 makes the sealing plate 314 stay in the third flow hole 313, blocking the third flow hole 313. At this time, the movable seat 31 can seal the port of the guide section 141 of the reactive gas inlet pipe 14 to achieve a seal and prevent backflow. The first elastic element 33 can also restrict the upward movement of the movable seat 31.
[0036] Furthermore, a limiting protrusion is formed on the inner wall of the guide section 141 (such as...). Figure 3 (As shown), to prevent the movable seat 31 from moving upwards excessively.
[0037] After the reaction gas is introduced, the pressure inside the reaction gas inlet pipe 14 gradually increases. Since the elastic coefficient of the second elastic element 34 is greater than that of the first elastic element 33, under pressure, the movable seat 31 will preferentially move downwards instead of the sealing plate 314 moving outwards. After the bottom of the sealing plate 314 passes the guide section 141, the sealing plate 314 cannot open due to the presence of the guide end 141. Therefore, the movable seat 31 can only continue to move downwards until it reaches a position where the sealing plate 314 can rotate (e.g., ...). Figure 3As shown in the diagram, at this time, the sealing plate 314 opens under pressure, allowing the reactive gas to enter the accommodating cavity 11 of the reaction shell. Since the third flow holes 313 are circumferentially spaced, the circumferential diffusion of the reactive gas increases the contact with the material. Due to the opening of the sealing plate 314, the pressure in the reactive gas inlet pipe 14 is correspondingly reduced, causing the first elastic element 33 and the second elastic element 34 to experience a reduction in pressure. The corresponding movable seat 31 will move upward, and the opening amplitude of the sealing plate 314 will decrease, achieving dynamic balance. Furthermore, since the minimum release pressure is controlled, the material can be displaced when the reactive gas is discharged, preventing the material from flowing back into the reactive gas inlet pipe 14.
[0038] During the release of the reaction gas, the impeller 35 can rotate under the flow of the reaction gas and drive the movable seat 31 to rotate, further increasing the diffusion of the reaction gas.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
