Description

Technical Field

[0001] This utility model relates to the field of chemical reactor technology, specifically a high-efficiency and energy-saving reactor for chemical preparation. Background Technology

[0002] In the chemical industry, reactors, as one of the core pieces of equipment, are widely used in the industrial production processes of various chemical reactions. With the escalating global energy crisis and increasingly stringent environmental protection requirements, the chemical industry has placed higher demands on reactor performance, especially in terms of improving reaction efficiency and reducing energy consumption.

[0003] Traditional chemical reactors typically employ relatively simple structural designs. For example, a batch reactor generally consists of a cylindrical body, a stirring device, and a heat transfer device, where materials are mixed through stirring within the reactor.

[0004] However, the impeller structure of such reactors has limitations: traditional impellers, such as anchor impellers and paddle impellers, have relatively simple blade designs, making it difficult to form a complex and uniform flow field throughout the reactor. Anchor impellers are mainly used for wall scraping, with limited disturbance to the fluid in the central region of the reactor; paddle impellers, when propelling material flow, are prone to stratification, with higher flow velocities near the impeller blades and lower velocities further away, resulting in insufficient and uneven mixing of materials. To address these issues, we propose a high-efficiency and energy-saving reactor for chemical preparation. Utility Model Content

[0005] The present invention aims to solve the technical problem that materials cannot be fully and uniformly mixed in the prior art.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency and energy-saving reactor for chemical preparation includes a reaction vessel with a built-in mixing component. The mixing component includes a servo motor, and a drive roller is fixedly connected to the output end of the servo motor. A rotating seat is fixedly connected to the bottom of the drive roller. Multiple partitions are fixedly connected around the rotating seat and are evenly distributed along the length of the rotating seat. Multiple inclined plates are sleeved on the surface of the rotating seat, and one side of each inclined plate is fixedly connected to the rotating seat. Multiple evenly distributed reaction chambers are formed between the inclined plates and the partitions. Flow holes are provided on the surfaces of the inclined plates and the partitions. A rotating inner cylinder is sleeved on the surfaces of the partitions and the inclined plates, and a rotating outer cylinder is sleeved on the outer ring wall of the rotating inner cylinder. A heating chamber is formed between the rotating inner cylinder and the rotating outer cylinder.

[0008] Preferably, the bottom of the reactor is fixedly connected with multiple evenly distributed support feet.

[0009] Preferably, a feed inlet is installed on one side of the top of the reactor, and multiple pressure relief valves are fixedly connected around the top of the reactor.

[0010] Preferably, a fixing seat is fitted onto the surface of the servo motor, and the end of the fixing seat away from the servo motor is fixedly connected to the top of the reactor.

[0011] Preferably, the end of the drive roller away from the servo motor extends through the surface of the reactor and into the reactor, and a rotating bearing is sleeved on the end of the drive roller inside the reactor.

[0012] Preferably, the outer ring wall of the rotating bearing is fitted with a closed disc, and the surface of the closed disc has multiple feed windows that penetrate through it. The outer ring wall of the closed disc is fixedly connected to the inner wall of the reactor.

[0013] Preferably, the surface of the reactor is surrounded by heating tubes, and the heating chamber is connected to the heating tubes.

[0014] Preferably, the outer ring wall of the rotating outer cylinder is fixedly connected with a plurality of evenly distributed scrapers.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] The reactor in this invention includes a reaction vessel with supporting feet at the bottom and a feed inlet and pressure relief valve at the top. Heating tubes surround the surface, and a heating chamber is formed between the rotating inner and outer cylinders, connected to the heating tubes. This indirect heating method allows for uniform heat diffusion, temperature gradient control, and reduction of localized overheating or overcooling, providing a stable thermal environment for the reaction and reducing energy consumption. The built-in mixing components are driven by a servo motor, with a drive roller rotating a rotating seat, partitions, and inclined plates. The inclined plates and partitions form multiple reaction chambers, which tumble the material during rotation, preventing stratification. Combined with flow holes on the surface, this promotes thorough mixing of materials in all areas, improving mixing efficiency and production efficiency. A scraper on the rotating outer cylinder scrapes off material from the inner wall, preventing residue. This design achieves high efficiency and energy saving. Not only does the heating method improve heat utilization, but the uniform material mixing also ensures a more complete reaction, reducing energy consumption from additional operations. Uniform heating and good mixing create a stable reaction environment, reducing side reactions, improving product quality, and ensuring the stability and reliability of the chemical preparation process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-5 As shown, this utility model provides a high-efficiency and energy-saving reactor for chemical preparation, including a reaction vessel 1. Multiple evenly distributed support legs 101 are fixedly connected around the bottom of the reaction vessel 1. A feed inlet 102 is installed on one side of the top of the reaction vessel 1, through which materials enter the reaction vessel 1. The position of the feed inlet 102 is designed to facilitate material feeding and can guide the initial distribution of the material to a certain extent, allowing it to fall relatively evenly into the mixing area below after entering the reaction vessel 1.

[0025] Multiple pressure relief valves 104 are fixedly connected around the top of the reactor 1. Heating pipes 103 surround the surface of the reactor 1. A heating chamber 213 is formed between the rotating inner cylinder 211 and the rotating outer cylinder 212, and the heating chamber 213 is connected to the heating pipes 103. The reactor 1 contains a mixing assembly 2. The heating pipes 103 surrounding the surface of the reactor 1 operate first, transferring heat to the heating chamber 213 formed between the rotating inner cylinder 211 and the rotating outer cylinder 212. Because the heating chamber 213 is connected to the heating pipes 103, heat can be evenly diffused within this relatively enclosed space, providing a stable and uniform thermal environment for the reaction of the materials inside the reactor 1. Compared to directly heating the materials inside the reactor 1, this indirect heating method can better control the temperature gradient, reduce local overheating or overcooling, and facilitate a stable reaction.

[0026] The mixing component 2 includes a servo motor 201, with a fixed base 202 fitted onto its surface. The end of the fixed base 202 away from the servo motor 201 is fixedly connected to the top of the reactor 1. A drive roller 203 is fixedly connected to the output end of the servo motor 201. The end of the drive roller 203 away from the servo motor 201 extends through the surface of the reactor 1 into its interior. A rotating bearing 204 is fitted onto the end of the drive roller 203 inside the reactor 1. A closed disc 205 is fitted onto the outer ring wall of the rotating bearing 204. Multiple feed windows 206 are provided on the surface of the closed disc 205. When the servo motor 201 is started, its output end drives the drive roller 203 to rotate. The fact that one end of the drive roller 203 extends through the surface of the reactor 1 and is connected to the closed disc 205 via the rotating bearing 204 ensures the stability of the rotation. The feed windows 206 on the closed disc 205 allow material to continuously enter the area of ​​the rotating seat 207 below.

[0027] Furthermore, a rotating seat 207 is fixedly connected to the bottom of the drive roller 203. Multiple partitions 208 are fixedly connected around the rotating seat 207, and these partitions 208 are evenly distributed along the length of the rotating seat 207. Multiple inclined plates 209 are fitted onto the surface of the rotating seat 207, with one side of each inclined plate 209 fixedly connected to the rotating seat 207. Multiple evenly distributed reaction chambers are formed between the inclined plates 209 and the partitions 208. The partitions 208 around the rotating seat 207 and the inclined plates 209 fitted onto its surface rotate synchronously with the drive roller 203. Multiple evenly distributed reaction chambers are formed between the inclined plates 209 and the partitions 208. During rotation, the inclined plates 209 play a crucial role, continuously turning over the material. Due to the even distribution of the reaction chambers, the material does not exhibit the stratification phenomenon of high flow velocity in the blade area and slow flow velocity further away from the blade area, as is seen in traditional paddle agitation. Instead, it is fully agitated and mixed in each reaction chamber, ensuring uniform distribution of the material throughout the entire reactor 1 and greatly improving the mixing effect.

[0028] Furthermore, flow holes 210 are provided on the surfaces of the inclined plate 209 and the partition plate 208. A rotating inner cylinder 211 is sleeved on the surfaces of the partition plate 208 and the inclined plate 209. A rotating outer cylinder 212 is sleeved on the outer ring wall of the rotating inner cylinder 211. Multiple evenly distributed scrapers 214 are fixedly connected to the outer ring wall of the rotating outer cylinder 212. The flow holes 210 on the surfaces of the inclined plate 209 and the partition plate 208 further promote the flow of materials between different areas, making the mixing of materials more thorough. At the same time, the multiple evenly distributed scrapers 214 fixedly connected to the outer ring wall of the rotating outer cylinder 212 play a role. As the rotating outer cylinder 212 rotates, the scrapers 214 move between the outer cylinder and the inner wall of the reactor 1, scraping off the material adhering to the inner wall of the reactor 1, preventing the material from being difficult to discharge.

[0029] The unique design of the mixing component 2 completely solves the problem of uneven material mixing in traditional stirring methods. Through the synergistic effect of multiple reaction chambers and the inclined plate 209, the material can be fully stirred in all areas of the reactor 1, achieving rapid and uniform mixing, which greatly shortens the time required for the reaction to reach a uniform state and improves production efficiency.

[0030] The heating method of heating tube 103 and heating chamber 213 improves heat utilization. Compared with direct heating of materials, this method reduces heat loss to the environment, and heat can be transferred to the reactants more accurately, resulting in lower energy consumption. Because the materials are mixed evenly, the reaction proceeds more fully, reducing the energy consumption of additional operations such as repeated heating and stirring due to incomplete reaction. The energy consumption is reduced from the reaction process itself, achieving an overall high efficiency and energy saving effect.

[0031] Uniform heating and good material mixing create a stable reaction environment, making the reaction process more stable and reducing side reactions caused by uneven temperature or poor material mixing. This helps improve product quality and ensures the stability and reliability of the chemical preparation process.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
