Description

Technical Field

[0001] This utility model relates to the field of adsorbent preparation technology, specifically a heating device for adsorbent preparation. Background Technology

[0002] Yellow phosphorus processing involves chemical production. The exhaust gas produced during the production of yellow phosphorus contains a variety of volatile organic pollutants, such as carbon monoxide, hydrogen sulfide, and hydrogen fluoride. These need to be purified by adsorbents. VOC is the abbreviation for volatile organic compounds. In the general sense, VOC refers to volatile organic compounds. However, in the environmental sense, it refers to a class of reactive volatile organic compounds, that is, the kind of volatile organic compounds that can cause harm. Common VOC adsorbents include activated carbon. The existing patent authorization announcement number CN219400185U discloses a heating device for preparing VOC adsorbents. With the power of a rotating motor, the working column and multiple rotating tubes can be rotated. This, combined with the setting of structures such as exhaust holes, allows the gas extraction and gas filling operations to be completed more fully, thereby enabling the preparation reaction to be completed with higher quality. At the same time, since the connection between the fixed tube and the working tube is located inside the working vessel, it can effectively ensure that the rotation and gas extraction and filling operations do not interfere with each other, while effectively avoiding the problem of gas leakage outside the working vessel. In the aforementioned patent, the activation gas is repeatedly contacted with the material by rotating the multi-layered rotating tubes located inside the working vessel and filling the exhaust port with gas. However, the material inside the working vessel is difficult to turn over effectively, resulting in insufficient contact between the material that is far from the exhaust port and the activation gas. Summary of the Invention

[0003] The purpose of this invention is to provide a heating device for adsorbent preparation, in order to solve the problem mentioned in the background art that the material is located in the working vessel and is difficult to be effectively turned, resulting in insufficient contact between the material far from the exhaust port and the activation gas.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heating device for adsorbent preparation, comprising a base and a working vessel fixedly installed on the top of the base, a vessel lid fixedly installed on the top of the working vessel, and a material turning and gas injection assembly and a heating assembly arranged inside the base; the material turning and gas injection assembly includes a material turning inner cylinder fixedly installed in the middle of the base, a conveying auger rotatably installed inside the material turning inner cylinder, annularly spaced openings on the side wall at the lower end of the material turning inner cylinder, a gas injection pipe fixedly connected to the top of the conveying auger, vertical pipes fixedly connected to both ends of the gas injection pipe, multiple branch pipes fixedly installed vertically and equidistantly on the outside of the vertical pipe, a drive motor fixedly installed on the top of the vessel lid, and meshing transmission gears fixedly installed on the outside of the output shaft of the drive motor and the outside of the gas injection pipe, respectively.

[0005] Preferably, the conveying auger is fitted to the inner wall of the turning cylinder, the conveying auger is coaxial with the turning cylinder, and the bottom of the working vessel is funnel-shaped, narrowing towards the opening.

[0006] Preferably, the gas injection pipe is arranged in a cross shape, and a rotary joint located outside the vessel lid is fixedly connected to the top end of the gas injection pipe.

[0007] Preferably, the outer side of the branch pipe is provided with equidistant air holes in an annular shape.

[0008] Preferably, a limiting ring is fixedly installed on the upper part of the inner sidewall of the base, and limiting rods that are locked in the limiting ring are fixedly installed at both ends of the air injection pipe.

[0009] Preferably, the heating assembly includes a control box, a first jacket, and a second jacket. The control box is fixedly installed on the top of the base, the first jacket is fixedly installed on the inner side wall of the base, and the second jacket is fixedly installed on the outer side wall of the gas injection pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The air injection pipe and conveying auger are driven by the drive motor to rotate.

[0014] 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.

[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a heating device for adsorbent preparation, including a base 1 and a working vessel 2 fixedly installed on the top of the base 1. A vessel lid 3 is fixedly installed on the top of the working vessel 2. The base 1 is equipped with a material turning and gas injection assembly 4 and a heating assembly 5. The material turning and gas injection assembly 4 includes a material turning inner cylinder 41 fixedly installed in the middle of the base 1. A conveying auger 42 is rotatably installed inside the material turning inner cylinder 41. An annularly spaced through-hole 43 is opened on the side wall at the lower end of the material turning inner cylinder 41. A gas injection pipe 44 is fixedly connected to the top of the conveying auger 42. Vertical pipes 45 are fixedly connected to both ends of the gas injection pipe 44. Multiple branch pipes 46 are fixedly installed vertically and equidistantly on the outside of the vertical pipes 45. A drive motor 47 is fixedly installed on the top of the vessel lid 3. The output shaft of the drive motor 47 is connected to the gas injection pipe. Transmission gears 48 that mesh with each other are fixedly installed on the outside of the pipe 44. After the drive motor 47 is started, the transmission gear 48 outside its output shaft meshes with the transmission gear 48 outside the air injection pipe 44 to achieve transmission, driving the air injection pipe 44 to rotate. The air injection pipe 44 is connected and fixed to the conveying auger 42 through a coupling, driving the conveying auger 42 to rotate. The conveying auger 42 rotates inside the turning inner cylinder 41, conveying the material entering the conveying auger 42 from the port 43 upward along the turning inner cylinder 41 and spreading outward from the top of the turning inner cylinder 41, thereby effectively turning the material. When the air injection pipe 44 rotates, it synchronously drives the vertical pipes 45 on the left and right sides to rotate. When the vertical pipes 45 rotate, they drive the branch pipes 46 to stir in the material. The activation gas is discharged from the branch pipes 46, thereby ensuring the uniform turning of the material and the full contact between the activation gas and the material.

[0016] The conveying auger 42 is set close to the inner wall of the turning inner cylinder 41, and the conveying auger 42 and the turning inner cylinder 41 are set on the same axis. The bottom of the working vessel 2 is set in a funnel shape that narrows towards the opening 43, so that the material can quickly gather at the bottom of the turning inner cylinder 41 and be conveyed by the conveying auger 42. This avoids the problem of material accumulation at the bottom of the working vessel 2, which would lead to untimely conveying. At the same time, the funnel-shaped structure can also reduce the material residue at the bottom of the working vessel 2. The setting of the conveying auger 42 close to the inner wall of the turning inner cylinder 41 further enhances the material conveying effect, ensuring that the material in the turning inner cylinder 41 can be fully conveyed upward and dispersed, forming a more efficient contact reaction environment with the activation gas discharged from the branch pipe 46.

[0017] The gas injection pipe 44 is arranged in a cross shape. The top end of the gas injection pipe 44 is fixedly connected to a rotary joint 411 located outside the kettle cover 3. The other end of the rotary joint 411 is connected to an external gas source pipeline, so that the gas injection pipe 44 can always maintain a stable connection with the external gas source during the rotation of the inner cylinder 41. This ensures that the activation gas can continuously enter the vertical pipe 45 and the branch pipe 46 through the gas injection pipe 44. The cross-shaped structure allows the gas injection pipe 44 to extend connection ends in four directions at the same time, so that it can be easily fixedly connected to the vertical pipes 45 on the left and right sides. This ensures the stability of the vertical pipes 45 during rotation and also allows the activation gas to be evenly distributed to each vertical pipe 45. Then, it is evenly released into the material through the branch pipe 46, further improving the uniformity and fullness of the contact between the activation gas and the material.

[0018] The outer ring of the branch pipe 46 is provided with equidistant air holes. The diameter of the air holes gradually decreases from the end closer to the vertical pipe 45 to the end farther away from the vertical pipe 45. This allows the amount of activation gas emitted from different positions of the branch pipe 46 to be more balanced, ensuring that the activation gas can be stably and evenly sprayed out from the air holes of the branch pipe 46, making full contact with the surrounding materials and promoting the full progress of the activation reaction.

[0019] A limiting ring 410 is fixedly installed on the upper part of the inner side wall of the base 1. Both ends of the gas injection pipe 44 are fixedly installed with limiting rods 49 that are locked in the limiting ring 410. The ends of the limiting rods 49 slide in contact with the inner ring surface of the limiting ring 410. When the gas injection pipe 44 rotates, it can effectively limit the gas injection pipe 44 in the circumferential direction, preventing the gas injection pipe 44 from radially deviating during the rotation process. This ensures the connection stability between the gas injection pipe 44 and the vertical pipe 45 and the branch pipe 46, and avoids the stable delivery of the activation gas due to the shaking of the gas injection pipe 44. The setting of the limiting ring 410 provides a stable support track for the limiting rods 49, making the rotation process of the gas injection pipe 44 more stable and smooth.

[0020] Please see Figure 1 , Figure 2 and Figure 5The heating assembly 5 includes a control box 51, a first jacket 52, and a second jacket 53. The control box 51 is fixedly installed on the top of the base 1. The first jacket 52 is fixedly installed on the inner side wall of the base 1. The second jacket 53 is fixedly installed on the outer side wall of the air injection pipe 44. Heating plate 1 54 and heating plate 2 55 are respectively fixedly installed inside the first jacket 52 and the second jacket 53. The first jacket 52 and the second jacket 53 are respectively located on the side walls of the base 1 and the air injection pipe 44. The control box 51 connects the first jacket 52 and the second jacket 53 with the heating plate 1 54 and the heating plate 2 55 inside the second jacket 53. After heating plates 1 and 2 are heated, the heat is conducted to the material inside the base 1 through jackets 1 and 2. By heating both the inner and outer sides of the material simultaneously, the heating efficiency is improved, and the material is heated more evenly. The control box 51 is controlled by a PLC, which can adjust the output power of heating plates 1 and 2 according to the actual process requirements to achieve precise control of the heating temperature. The fixed connection between jacket 1 and the inner wall of the base 1 ensures that the heat can be efficiently transferred to the material body inside the base 1.

[0021] Jacket 1 52 and Jacket 2 53 are connected. Heating plate 1 54 and Heating plate 2 55 are both electrically connected to control box 51. The connection design between jacket 1 52 and jacket 2 53 can realize the internal heat circulation and complementarity and facilitate wiring. Heating plate 1 54 and Heating plate 2 55 are controlled by control box 51 through electrical connection, so that control box 51 can control the working status and adjust the temperature in real time.

[0022] Working principle: The material is located inside the base 1. The drive motor 47 is started, which drives the transmission gear 48 that meshes with the output shaft of the motor and the air injection pipe 44 to rotate. The air injection pipe 44 is connected and fixed to the conveying auger 42 through a coupling, which in turn drives the conveying auger 42 to rotate. The conveying auger 42 rotates inside the turning cylinder 41, and the material that enters the conveying auger 42 through the port 43 is conveyed upward along the turning cylinder 41 and spread outward from the top of the turning cylinder 41, which can effectively turn the material. When the air injection pipe 44 rotates, it drives the vertical pipes 45 on the left and right to rotate. When the vertical pipes 45 rotate, they drive the branch pipes 46 to rotate and stir inside the material. The air injection pipe 44 is connected to an external air source through the rotary joint 411 for inflation. The activation gas enters the vertical pipe 45 through the air injection pipe 44 and is discharged from the air hole on the branch pipe 46, which can ensure that the activation gas is in full contact with the material. The first jacket 52 and the second jacket 53 are respectively installed on the base 1 and the air injection pipe 44. The control box 51 connects the first heating plate 54 and the second heating plate 55 in the first jacket 52 and the second jacket 53. The heating plate 54 and the second heating plate 55 heat up and transfer heat through the first jacket 52 and the second jacket 53 to the material in the base 1 for heating. By heating the material from both the inside and outside, the heating efficiency is improved. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
