Description

Technical Field

[0001] This utility model relates to the technical field of reactor sealing components, and in particular to a polyether sealant high-temperature reactor sealing component. Background Technology

[0002] In modern chemical production fields such as chemical industry, pharmaceutical industry, and new materials, high-temperature reactors are the core equipment for key chemical reactions such as polymerization, condensation, and esterification. The sealing performance of the reactor is directly related to the safety of production, the stability of product quality, energy consumption, and environmental protection. It is one of the core indicators for measuring the technical level of reactors. The sealing between the lid and body of a high-temperature reactor mainly relies on gasket seals and mechanical seals.

[0003] Traditional sealing components typically rely on a single sealing element, which makes it difficult to maintain optimal sealing conditions at all times. The effects of thermal expansion and contraction may cause changes in the sealing preload, resulting in incomplete sealing and increasing the risk of leakage.

[0004] Therefore, those skilled in the art have provided a polyether sealant high-temperature reactor sealing assembly to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a polyether sealant sealing assembly for high-temperature reactors. This assembly first injects water to form a liquid seal, and then uses a rubber ring for a secondary mechanical seal. This device constructs a double protective barrier, effectively intercepting leaks, reducing the risk of major accidents, and ensuring the long-term safe, reliable, and durable operation of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polyether sealant high-temperature reactor sealing assembly includes a reactor body and a cover plate. A stirring mechanism is provided on the inner wall of the reactor body, and a sealing mechanism is provided on the outside of the reactor body and the cover plate. The sealing mechanism includes multiple fixing blocks. A first connecting ring is fixedly connected to the lower end of the outer wall of the cover plate, and a second connecting ring is fixedly connected to the upper end of the outer wall of the reactor body. An installation block is fixedly connected to the lower edge of the cover plate. A slot is formed at the upper edge of the reactor body. A sealing ring is provided at the lower edge of the first connecting ring, and a sealing groove is formed at the upper end of the second connecting ring. The sides of adjacent fixing blocks near the center of the reactor body are fixedly connected to the first and second connecting rings. Rotating columns are rotatably connected to the lower ends of each fixing block. Threaded sections are provided at the upper ends of multiple rotating columns, and threaded sleeves are threadedly connected to multiple threaded sections.

[0008] The above technical solution involves filling the empty tank with water, causing the mounting block to fit tightly against the upper end of the empty tank under liquid pressure, forming a preliminary seal with liquid as the medium. On this basis, the cooperation between the sealing ring and the sealing groove constitutes a second mechanical seal, which can effectively intercept the leaked medium, reduce the risk of major leakage accidents, and improve the safety, reliability and durability of the entire device.

[0009] Furthermore, a protective box is fixedly connected to the upper end of the cover plate, a servo motor is fixedly connected to the upper end of the inner wall of the protective box, a stirring column is rotatably connected to the bottom surface of the reactor body, a fixing ring is fixedly connected to both ends of the outer wall of the stirring column, a crossbar is fixedly connected to both sides of the two fixing rings, a scraper is fixedly connected to the side of the adjacent crossbar away from the center of the reactor body, and stirring blades are uniformly fixedly connected to the outer wall of the stirring column.

[0010] The above technical solution involves starting a servo motor to drive the stirring column to rotate. As the stirring column rotates, the stirring blades also rotate, stirring the material in the reactor body. At this time, the scraper removes the material adhering to the inside of the reactor body, shortening the cleaning time after production and reducing the downtime of the equipment.

[0011] Furthermore, a feed inlet is connected through one side of the upper end of the cover plate, and a discharge outlet is connected through one side of the lower end of the reactor body.

[0012] Through the above technical solutions, the inlet and outlet provide standardized and controllable channels for the precise input of raw materials and the smooth output of finished products.

[0013] Furthermore, the outer wall of the mounting block is fitted with the upper end of the inner wall of the slot;

[0014] The above technical solution greatly reduces the gap between the two, forming a tight, non-dead-angle preliminary seal with the upper end of the empty groove.

[0015] Furthermore, the lower ends of all of the threaded sleeves are in contact with the upper end of the upper fixing block;

[0016] The above technical solution prevents the rotating column from rotating and disengages it from the first connecting ring.

[0017] Furthermore, the output end of the servo motor is fixedly connected to the upper end of the stirring column, and the upper end of the stirring column extends through the cover plate to the outside of the cover plate;

[0018] The above technical solution reduces the number of transmission components and enables high-precision speed control.

[0019] Furthermore, the outer walls of the two scrapers are in contact with the inner wall of the reactor body;

[0020] The above technical solution allows the scraper to remove materials adhering to the inside of the reactor body, shortening the cleaning time after production.

[0021] Furthermore, the sealing ring fits into the sealing groove;

[0022] Through the above technical solutions, the polyether sealing ring has excellent resistance to high and low temperatures, chemical corrosion, and aging.

[0023] This utility model has the following beneficial effects:

[0024] 1. The polyether sealant high-temperature reactor sealing assembly proposed in this utility model fills the empty tank with water, so that the mounting block and the upper end of the empty tank are tightly fitted under liquid pressure, forming a preliminary seal with liquid as the medium. On this basis, the cooperation between the sealing ring and the sealing groove constitutes a second mechanical seal, which can effectively intercept the leaked medium, reduce the risk of major leakage accidents, and improve the safety, reliability and durability of the entire device.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specific embodiment: a polyether sealant high-temperature reactor sealing assembly, including a reactor body 3 and a cover plate 4. A stirring mechanism 2 is provided on the inner wall of the reactor body 3, and a sealing mechanism 1 is provided on the outside of the reactor body 3 and the cover plate 4. The sealing mechanism 1 includes multiple fixing blocks 107. A first connecting ring 101 is fixedly connected to the lower end of the outer wall of the cover plate 4, a second connecting ring 102 is fixedly connected to the upper end of the outer wall of the reactor body 3, and an mounting block 103 is fixedly connected to the lower edge of the cover plate 4. A slot 104 is provided at the upper edge of the reactor body 3. A sealing ring 105 is provided at the lower edge of the first connecting ring 101. A sealing groove 106 is provided at the upper end of the second connecting ring 102. The side of the adjacent fixing block 107 near the center of the reactor body 3 is fixedly connected to the first connecting ring 101 and the second connecting ring 102. The lower fixing block 107 is rotatably connected to a rotating column 108. The upper end of the multiple rotating columns 108 is provided with a threaded section 109. The multiple threaded sections 109 are threadedly connected to a threaded sleeve 110.

[0036] By filling the empty tank 104 with water, the mounting block 103 and the upper end of the empty tank 104 are tightly fitted under liquid pressure, forming a preliminary seal with liquid as the medium. On this basis, the cooperation between the sealing ring 105 and the sealing groove 106 constitutes a second mechanical seal, which can effectively intercept the leaked medium, reduce the risk of major leakage accidents, and improve the safety, reliability and durability of the entire device.

[0037] Reference Figure 3 , Figure 4 and Figure 5A protective box 201 is fixedly connected to the upper end of the cover plate 4. A servo motor 202 is fixedly connected to the upper end of the inner wall of the protective box 201. A stirring column 203 is rotatably connected to the bottom surface of the reactor body 3. Fixing rings 204 are fixedly connected to both ends of the outer wall of the stirring column 203. Crossbars 205 are fixedly connected to both sides of the two fixing rings 204. Scrapers 206 are fixedly connected to the side of the adjacent crossbars 205 away from the center of the reactor body 3. Stirring blades 207 are evenly fixedly connected to the outer wall of the stirring column 203. When the servo motor 202 is started, it drives the stirring column 203 to stir. The column 203 rotates, and as the column 203 rotates, the stirring blade 207 rotates accordingly, stirring the material in the reactor body 3. At this time, the scraper 206 scrapes off the material adhering to the inside of the reactor body 3, shortening the cleaning time after production and reducing the downtime of the equipment. The upper side of the cover plate 4 is connected to the feed port 5, and the lower side of the reactor body 3 is connected to the discharge port 6. The feed port 5 and the discharge port 6 provide a standard and controllable channel for the precise input of raw materials and the smooth output of finished products.

[0038] The outer wall of the mounting block 103 fits against the upper end of the inner wall of the empty groove 104, greatly reducing the gap between them and forming a tight, dead-angle-free preliminary seal with the upper end of the empty groove 104. The lower ends of multiple threaded sleeves 110 are all fitted against the upper end of the upper fixing block 107 to prevent the rotating column 108 from rotating and to release the first connecting ring 101. The output end of the servo motor 202 is fixedly connected to the upper end of the stirring column 203. The upper end of the stirring column 203 penetrates through the cover plate 4 to the outside of the cover plate 4, reducing the number of transmission parts and enabling high-precision speed control. The outer walls of the two scrapers 206 fit against the inner wall of the reactor body 3. The scrapers 206 scrape off the material adhering to the inside of the reactor body 3, shortening the cleaning time after production. The sealing ring 105 fits against the sealing groove 106. The polyether sealing ring 105 has excellent resistance to high and low temperatures, chemical corrosion, and aging.

[0039] Working principle: The user first fills the empty tank 104 with water, then aligns the mounting block 103 with the empty tank 104 and fits it against the upper part of the empty tank 104. The fluidity of the water allows it to "wet" and "fill" these gaps, forming a preliminary liquid seal. At this time, the sealing ring 105 and the sealing groove 106 cooperate to form a secondary seal, effectively intercepting the leaked medium and reducing the risk of major leakage accidents. After sealing, the rotating column 108 is rotated to make it vertical, and then the threaded sleeve 110 is unscrewed to fit against the upper fixing block 107, so that the cover plate 4 can be firmly installed on the reactor body 3. Then, the servo motor 202 is started by the external controller, which drives the stirring column 203 to rotate. As the stirring column 203 rotates, the stirring blade 207 rotates accordingly, stirring the material in the reactor body 3. At this time, the scraper 206 scrapes off the material adhering to the inside of the reactor body 3, shortening the cleaning time after production and reducing the downtime of the equipment.
