A chemical raw material reaction equipment

Abstract

This utility model discloses a chemical raw material reaction device, belonging to the technical field of chemical production. It includes a reactor body with a lid on top and a semi-circular ball valve located at the lower interior of the reactor body. A return channel and a discharge channel are respectively opened on both sides of the semi-circular ball valve. Thus, the semi-circular ball valve at the lower interior of the reactor body can flexibly switch channel states via a controller. When the discharge channel is blocked, the material at the bottom of the reactor flows into the return channel under gravity. The auger in the return mechanism rotates at high speed under the drive of a second motor, conveying the material upwards along the return channel and returning it to the interior of the reactor body, forming a closed-loop cycle. This solves the problem of static accumulation of material at the bottom of traditional reactors, ensuring that all materials can participate in the reaction. Furthermore, the synergistic effect of the stirring mechanism and the return mechanism allows the material returning to the reactor body to quickly mix with the main material, improving overall mixing uniformity. This is particularly suitable for reaction scenarios involving high-viscosity and high-solids-content materials.

Description

Technical Field

[0001] This utility model relates to a chemical raw material reaction device, belonging to the technical field of chemical production. Background Technology

[0002] In the chemical, pharmaceutical, and food industries, reaction vessels are core equipment for realizing processes such as material mixing, reaction, and polymerization. The degree of uniform mixing of materials inside the vessel directly affects product quality and reaction efficiency.

[0003] Traditional reactor stirring systems mostly rely on top-mounted impellers to move materials. However, due to the gap between the bottom of the reactor and the impeller, and the potential formation of dead zones in the bottom corners and edges, the materials are difficult to stir fully. Especially when the materials have high viscosity or contain a large number of solid particles, gravity will cause the materials to gradually settle at the bottom of the reactor, forming a static accumulation layer. These accumulated materials not only cannot participate in the normal reaction, but also the uneven mixing of the accumulated materials with the main materials in the reactor will lead to a decrease in reaction conversion rate and product purity, increasing the difficulty of subsequent separation and purification. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a chemical raw material reaction equipment that enables real-time circulation of materials at the bottom of the reactor and effectively prevents accumulation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a chemical raw material reaction equipment, characterized in that it includes: a vessel body, a vessel cover is provided on the top of the vessel body, and a stirring mechanism for stirring materials is provided on the vessel cover; a semi-circular ball valve is provided at the bottom inside the vessel body, and a return channel and a discharge channel are respectively opened on both sides of the semi-circular ball valve.

[0006] The return channel is equipped with a return mechanism.

[0007] The outer side of the vessel body is also equipped with a lifting mechanism for raising and lowering the vessel lid.

[0008] Preferably, the stirring mechanism includes a motor, which is fixed to the top of the vessel lid, and a stirring rod is vertically arranged at the bottom of the vessel lid, the stirring rod being connected to the output end of the motor.

[0009] Preferably, a sealing ring is also fixed to the bottom of the vessel lid, and a controller for controlling the rotation of the semi-circular ball valve is fixed to the outside of the vessel body.

[0010] Preferably, the bottom of the vessel is conical, and a heater is provided on the inner wall of the vessel.

[0011] Preferably, the return material mechanism includes an auger, which is vertically arranged in the return material channel. A second motor is fixed to the top of the reactor body, and the output end of the second motor is connected to the auger.

[0012] Preferably, the lifting mechanism includes a lead screw, which is vertically arranged on the side of the vessel body. A motor is also fixed on the outside of the vessel body. The output end of the motor is connected to the lead screw, and a movable block is threaded onto the lead screw. One end of the movable block is slidably connected to the outer wall of the vessel body, and the other end of the movable block is connected to the vessel lid through a support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The semi-circular ball valve at the bottom of the vessel can be flexibly switched via a controller. When the discharge channel is blocked, the material at the bottom of the vessel flows into the return channel under gravity. The auger in the return mechanism rotates at high speed under the drive of motor 2, conveying the material upward along the return channel and returning it to the inside of the vessel, forming a closed loop. This solves the problem of static accumulation of material at the bottom of traditional reactors, ensuring that all materials can participate in the reaction. Furthermore, the synergistic effect between the stirring mechanism and the return mechanism allows the material returning to the vessel to mix quickly with the main material, improving the overall mixing uniformity. This is especially suitable for reaction scenarios involving high viscosity and high solid content materials.

[0015] The motor drives the lead screw to rotate, which in turn moves the movable block and support rod to lift and lower, enabling the easy opening and closing of the kettle lid. This facilitates material addition, equipment maintenance and cleaning, and reduces the difficulty of operation. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A chemical raw material reaction device includes: a vessel body 1, a vessel cover 2 is provided on the top of the vessel body 1, and a stirring mechanism 3 for stirring materials is provided on the vessel cover 2; a semi-circular ball valve 5 is provided at the lower interior of the vessel body 1, and a return channel and a discharge channel are respectively opened on both sides of the semi-circular ball valve 5.

[0024] The return channel is equipped with a return mechanism 8.

[0025] The outer side of the vessel body 1 is also equipped with a lifting mechanism 9 for lifting the vessel lid 2.

[0026] Furthermore, the stirring mechanism 3 stirs the material in the reactor, and the semi-circular ball valve 5 controls the opening and closing of the return channel and the discharge channel. During the reaction, the discharge channel is blocked, and the material is sent back to the reactor body 1 through the return channel by the return mechanism 8. After completion, the discharge channel is opened to discharge the material, and the lifting mechanism 9 drives the reactor cover 2 to rise and fall, which facilitates loading and maintenance.

[0027] In this embodiment: the stirring mechanism 3 includes a motor 301, which is fixed to the top of the lid 2, and a stirring rod 302 is vertically arranged at the bottom of the lid 2. The stirring rod 302 is connected to the output end of the motor 301.

[0028] Furthermore, the stirring rod 302 is rotated by the motor 301 to stir the material in the vessel 1, thereby enhancing the uniformity of the material mixing.

[0029] In this embodiment: a sealing ring 4 is also fixed at the bottom of the vessel lid 2, and a controller 6 for controlling the rotation of the semi-circular ball valve 5 is fixed on the outside of the vessel body 1.

[0030] Furthermore, when the lid 2 is closed, the sealing ring 4 fits against the top of the vessel body 1 to form a seal, preventing material leakage or the entry of external impurities and ensuring the airtightness of the reaction environment. The controller 6 controls the rotation angle of the semi-circular ball valve 5 through electrical signals to switch between the return channel and the discharge channel, making the operation convenient and precise.

[0031] In this embodiment: the bottom of the vessel body 1 is conical, and a heater is provided on the inner wall of the vessel body 1.

[0032] Furthermore, the conical bottom can guide the material to gather towards the bottom of the vessel 1, reducing material residue in the corners and facilitating the material to enter the return or discharge channel, thus improving material utilization. The heater can provide heat according to the reaction requirements, keeping the material in the vessel at a suitable temperature. Combined with the conical bottom structure design, the heat distribution is more uniform, avoiding local overheating or underheating that could affect the reaction.

[0033] In this embodiment: the return material mechanism 8 includes an auger 801, which is vertically arranged in the return material channel. A second motor 802 is fixed on the top of the vessel body 1, and the output end of the second motor 802 is connected to the auger 801.

[0034] Furthermore, when the semi-circular ball valve 5 blocks the unloading channel, the material at the bottom of the vessel enters the return channel, and the motor 802 is started. Its output end drives the auger 801 to rotate, and the material is transported upward along the return channel through the spiral blades, and finally returned to the inside of the vessel body 1, forming a material circulation and solving the bottom accumulation problem.

[0035] In this embodiment: the lifting mechanism 9 includes a lead screw 901, which is vertically arranged on the side of the vessel body 1. A motor 902 is also fixed on the outside of the vessel body 1. The output end of the motor 902 is connected to the lead screw 901. A movable block 903 is threadedly connected to the lead screw 901. One end of the movable block 903 is slidably connected to the outer wall of the vessel body 1, and the other end of the movable block 903 is connected to the vessel cover 2 through a support rod 904.

[0036] Furthermore, the motor 902 drives the lead screw 901 to rotate, causing the threaded movable block 903 to slide up and down along the outer wall of the vessel body 1. The support rod 904 drives the vessel lid 2 to rise and fall, realizing the automatic opening and closing of the vessel lid 2. This facilitates material addition, vessel cleaning, or equipment maintenance, and reduces the intensity of manual operation.

[0037] The workflow of this embodiment is as follows: Before adding materials, the semi-circular ball valve 5 at the bottom of the vessel body 1 is controlled by the controller 6 to rotate, causing the semi-circular ball valve 5 to rotate to block the discharge channel. After adding materials, the materials at the bottom of the vessel body 1, especially the materials gathered at the conical bottom, enter the return channel. After the motor 301 on the vessel cover 2 is started, it drives the vertically set stirring rod 302 to rotate, stirring the materials in the vessel body 1, so that the materials form a preliminary mixing flow field in the vessel, providing a basic mixing environment for the reaction. The second motor 802 is started simultaneously to drive the auger 801 in the return channel to rotate, using the thrust of the spiral blades to push the materials in the return channel... The material is conveyed upwards and eventually returned to the interior of the vessel 1, forming a closed-loop circulation. This prevents the material from accumulating at the bottom of the vessel and ensures that all materials can participate in the stirring reaction. After the reaction is completed, the semi-circular ball valve 5 is rotated by the controller 6 to block the return channel and open the discharge channel. The material inside the vessel is discharged through the discharge channel, achieving rapid collection of reaction products. When the operation is completed and the interior of the vessel 1 needs to be cleaned or maintained, the motor 902 is turned on to drive the lead screw 901 to rotate, which drives the threaded movable block 903 to slide along the outer wall of the vessel 1. The movable block 903 drives the vessel cover 2 to rise and fall through the support rod 904, facilitating the addition of materials or equipment maintenance.

[0038] 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.
