Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a device for preventing the internal walls of a polymerization furnace from forming slag. Background Technology

[0002] In the polymerization production of polymer materials, the polymerization furnace is the core equipment for realizing the monomer polymerization reaction. However, during the polymerization reaction, due to the chemical reaction of materials under high temperature and high pressure, some reaction products or unreacted monomers tend to adhere to and accumulate on the inner wall of the polymerization furnace, forming a wall-forming phenomenon. The formation of this wall-gathering phenomenon is mainly related to factors such as material characteristics, reaction temperature distribution, and furnace flow rate. For example, when the local temperature inside the polymerization furnace is too high, the material is prone to overheating decomposition or cross-linking reaction, generating solid substances that are difficult to flow and depositing on the furnace wall. In addition, uneven flow rate inside the furnace causes the material to stay in certain areas for too long, which also increases the probability of the material adhering to the furnace wall. The formation of aggregated walls has several adverse effects on polymerization production. First, as the thickness of the aggregated layer increases, the heat transfer efficiency of the polymerization furnace decreases significantly, leading to a substantial increase in energy consumption. It also affects the stability of the reaction temperature, thereby reducing the uniformity of product quality. Second, excessively thick aggregated layers may detach and mix into the product, reducing product purity and even clogging furnace channels, affecting the continuity of production. Furthermore, removing the aggregated layers requires periodic shutdowns for cleaning, which not only increases labor and equipment maintenance costs but also severely impacts production efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device to prevent the material adhering to the inside of the polymerization furnace wall. The device can shake and remove the material adhering to the wall of the polymerization furnace during the production process, thereby reducing the frequency of manual maintenance, effectively improving the production efficiency of high polymerization and reducing the production cost.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for preventing the wall from forming inside a polymerization furnace, including a polymerization furnace, wherein a rotary guide tube is provided on the outer wall of the polymerization furnace, and an impact ball is provided inside the rotary guide tube.

[0008] In a preferred embodiment, a buffer spring is provided inside the closed end of the first pipe section.

[0009] In a preferred embodiment, the impact ball within a single impact guide tube includes a main impact ball and a secondary impact ball, the combined diameter of which is greater than the inner diameter of the impact guide tube, and the main impact ball is positioned close to the polymerization furnace.

[0019] like Figure 1-4 Among them, a device for preventing the wall of a polymerization furnace is provided, including a polymerization furnace 1, wherein a rotary guide tube 2 is provided on the outer wall of the polymerization furnace 1, and an impact ball is provided inside the rotary guide tube 2.

[0020] In a preferred embodiment, there are multiple rotary guide tubes 2, which are arranged in a circumferential manner on the same vertical surface of the outer wall of the polymerization furnace 1.

[0021] In a preferred embodiment, the rotary guide tube 2 includes a first tube section 201 and a second tube section 202, and the first tube section 201 and the second tube section 202 are welded together to form a zigzag-shaped tube.

[0022] In a preferred embodiment, the first pipe section 201 is open at one end, the second pipe section 202 is open at both ends, the open end of the first pipe section 201 is welded and fixed to one end of the second pipe section 202, and the other end of the second pipe section 202 is fixed to the outer wall of the polymerization furnace 1.

[0023] In a preferred embodiment, a buffer spring 3 is provided inside the closed end of the first tube section 201.

[0024] In a preferred embodiment, the impact ball within a single rotary guide tube 2 includes a main impact ball 4 and a secondary impact ball 5. The combined diameter of the main impact ball 4 and the secondary impact ball 5 is greater than the inner diameter of the rotary guide tube 2. The main impact ball 4 is positioned close to the polymerization furnace 1.

[0025] In a preferred embodiment, the main impact ball 4 and the secondary impact ball 5 are connected by an elastic connecting rope 6.

[0026] In a preferred embodiment, a plurality of guide plates 7 are arranged circumferentially on the side wall of the first pipe section 201 near the closed end. Part of the guide plate 7 extends into the rotary guide tube 2, and the part of the guide plate 7 inside the rotary guide tube 2 is provided with a bevel 701.

[0027] In a preferred embodiment, the device further includes a fixing seat 10 fixed to the outer wall of the polymerization furnace 1, and the outer wall of the fixing seat 10 is provided with a second external thread 11; The second pipe section 202 has a first external thread 9 on the outer wall of the end away from the first pipe section 201, and a threaded sleeve 8 is provided on the first external thread 9.

[0028] The device disclosed in this utility model for preventing wall adhesion inside a polymerization furnace, during operation: The polymerization furnace 1 rotates and drives the rotary guide tube 2 to rotate around the axis of the polymerization furnace 1. When the rotary guide tube 2 moves to the high position, the main impact ball 4 moves towards the outer wall of the polymerization furnace 1 inside the rotary guide tube 2 until it impacts the polymerization furnace 1. During the process, the elastic connecting rope 6 generates elastic force and drives the secondary impact ball 5 to generate a secondary impact, thereby enhancing the impact effect.

[0029] When the rotary guide tube 2 moves to the low position, the main impact ball 4 and the secondary impact ball 5 move towards the closed end of the first tube section 201. Under the action of the guide plate 7, the buffer spring 3 is compressed. Through the buffering effect of the buffer spring 3, excessive impact force is avoided to prevent damage to the rotary guide tube 2. The continuous rotation of the polymerization furnace 1 drives the impact of multiple impact balls in the rotary guide tube 2, which can effectively prevent the material from forming on the inner wall of the polymerization furnace 1.
