Description

Technical Field

[0001] This utility model belongs to the technical field of chemical reaction devices, specifically relating to a desktop automated chemical reaction device. Background Technology

[0002] A chemical reaction apparatus is a general term for the equipment or systems used to carry out chemical reactions. These apparatuses are designed to provide the necessary environmental conditions for chemical reactions, such as temperature, pressure, stirring, and mixing, to ensure that the reaction proceeds along the intended path and yields the desired products.

[0003] Application No. 202221817026.1 discloses a polymer chemical reaction apparatus that "achieves stirring of substances through the cooperation of a reaction vessel, top cover, stirring motor, first perforated holding block, and stirring rod; and achieves catalyst holding through the cooperation of the first perforated holding block, second perforated holding block, and perforated placement dish, avoiding the need for catalyst filtration after the reaction. It also solves the problem that in existing polymer chemical reactions, the catalyst is often directly added to the raw materials, leading to the need for catalyst filtration after the reaction, thus reducing production efficiency." However, although the above operation successfully achieves the effective separation of some catalysts, a large amount of fixed raw material waste generated during the reaction, such as unreacted solid particles, byproducts, and other residues, still exists in the liquid product. The retention of these wastes not only significantly affects the purity and quality of the final product but may also interfere with subsequent separation, purification, or other processing steps, increasing operational difficulty and cost. Furthermore, the waste residue may also cause equipment blockage, corrosion, or contamination, further affecting production efficiency and equipment lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a desktop automated chemical reaction device to solve the problem mentioned in the background art where a large amount of waste generated by the reaction remains, affecting product quality and causing subsequent processing and equipment problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a desktop automated chemical reaction device, comprising: a reaction vessel, wherein a first reaction unit and a second reaction unit are provided inside the reaction vessel, a storage tank is provided at the bottom of the reaction vessel, and the first reaction unit and the second reaction unit are both connected to the storage tank, a bottom cover is installed at the bottom of the outer wall of the reaction vessel, and filter screens are installed at the top and bottom of the inner wall of the storage tank, and piston assemblies are provided in both the first reaction unit and the second reaction unit;

[0006] A support plate is provided on one side of the reactor, and a support plate is provided on one side of the support plate. A connecting plate is installed between the support plate and the reactor, and a rotating component and a rolling component are provided between the support plate and the support plate.

[0007] Preferably, the piston assembly includes an electric telescopic rod and a piston plate. The electric telescopic rod is installed inside the reactor, and the output end of the electric telescopic rod extends into the first reaction unit and the second reaction unit. The piston plate is installed at the output end of the electric telescopic rod.

[0008] The rotating assembly includes a servo motor and a rotating shaft. The servo motor is mounted on the outer wall of the support plate, and the rotating shaft is connected to the output end of the servo motor. The end of the rotating shaft away from the servo motor is connected to the outer wall of the support plate.

[0009] The rolling assembly includes a ball groove, a rolling ball, and a rolling channel. The ball groove is located on the upper surface of the support plate, and the rolling ball is installed within the ball groove. The rolling channel is located on the lower surface of the support plate. The rolling ball and the rolling channel are adapted to each other. When the support plate and the support plate rotate relative to each other, the rolling ball rotates on its own axis within the ball groove and simultaneously revolves within the rolling channel. This motion converts the sliding friction between the support plate and the support plate into rolling friction, thereby effectively reducing friction and achieving a labor-saving effect.

[0010] The side walls of the first and second reaction units are both connected to liquid inlet pipes, and the bottom of the reaction vessel is connected to a liquid outlet pipe.

[0011] The storage tank is connected to a feed pipe and a gas guide pipe on its side wall. The side walls of the liquid inlet pipe, liquid outlet pipe, feed pipe and gas guide pipe are all equipped with corresponding valves. The gas guide pipe facilitates the gas pressure balance of the reactor and facilitates the discharge of liquid.

[0012] Through the above technical solution:

[0013] In use, solid raw materials are transported to the storage tank through the feed pipe. Since the top and bottom of the inner wall of the storage tank are equipped with filter screens, the solid raw materials will be trapped in the storage tank, achieving solid-liquid separation.

[0014] Activate the electric telescopic rod to move the piston plate in the first reaction unit to the top of the first reaction unit, and simultaneously move the piston plate in the second reaction unit to the bottom of the second reaction unit. This operation ensures that the piston plates are in their initial positions, preparing for the subsequent addition of liquid feedstock.

[0015] Liquid raw materials are introduced into the first reaction unit through the feed pipe. After the liquid raw materials are introduced, all valves are closed to ensure the reactor's airtightness. Subsequently, the electric telescopic rods and servo motor are activated, causing the electric telescopic rods on both sides to extend and retract alternately, pushing the piston plate up and down within the reaction unit. Due to the movement of the piston plate, the liquid flows alternately between the first and second reaction units, achieving dynamic circulation within the reaction unit. The liquid then comes into full contact with the solid raw materials through the storage tank, achieving a solid-liquid mixing reaction. The reciprocating motion of the piston plate not only promotes liquid flow but also enhances the uniformity of solid-liquid mixing through stirring, ensuring that the reactants are evenly distributed within the reaction system and avoiding incomplete local reactions. The servo motor drives the support plate and reactor to rotate via a shaft. Through rotation, the materials within the reactor are continuously redistributed under centrifugal force, further enhancing the mixing effect and ensuring a complete reaction.

[0016] The alternating compression and circulation of the piston plates, combined with the rotational motion of the reactor, form a dynamic mixing system that allows the liquid raw materials to fully contact the solid raw materials, avoiding the problem of incomplete local reactions.

[0017] Open the valve on the liquid outlet pipe to allow the reacted liquid to drain smoothly from the storage tank. Because filters are installed at the top and bottom of the storage tank's inner wall, the liquid can flow out quickly, while solid residue is retained within the tank, preventing it from being discharged with the liquid and thus achieving solid-liquid separation. Finally, open the bottom cover of the reactor, remove the filters, and directly remove the solid residue from the storage tank. This design, by installing filters in the storage tank, enables rapid liquid discharge after the reaction and effective retention of solid residue, avoiding the additional steps of filtration and centrifugation required in traditional solid-liquid separation. This method simplifies the operation process, reduces manual intervention and equipment requirements, improves separation efficiency and operational safety, while lowering equipment costs and maintenance difficulty, making the entire reaction process more efficient, convenient, and safe.

[0018] If solid feedstock needs to be added midway, drain the reaction solution through the liquid outlet pipe before adding the new solid feedstock. Then, continue to add solid and liquid feedstocks separately according to the above steps to ensure the continuity and stability of the reaction process.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By setting up a storage tank and a filter screen, this utility model avoids the discharge of solid residue along with the liquid. When in use, the solid raw material is automatically intercepted by the filter screen in the storage tank, realizing solid-liquid separation and avoiding traditional filtration or centrifugation steps. After the reaction is completed, the liquid can be quickly discharged through the filter screen, while the solid residue remains in the storage tank for easy subsequent processing.

[0021] (2) This utility model achieves full mixing of solid and liquid by setting up an electric telescopic rod, a piston plate and a servo motor. When in use, the electric telescopic rod drives the piston plate to move up and down in the reaction unit, promoting the circulation of liquid between reaction units and achieving dynamic mixing; the servo motor drives the reaction vessel to rotate, using centrifugal force to redistribute the material, further enhancing the uniformity of solid-liquid mixing and avoiding insufficient local reaction.

[0027] 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.

[0028] Please see Figures 1-4 As shown, this utility model provides the following technical solution: a desktop automated chemical reaction device, comprising: a reaction vessel 1, a first reaction unit 2 and a second reaction unit 3 disposed inside the reaction vessel 1, a storage tank 4 disposed at the bottom of the reaction vessel 1, and the first reaction unit 2 and the second reaction unit 3 being interconnected with the storage tank 4, a bottom cover 5 installed at the bottom of the outer wall of the reaction vessel 1, and filter screens 6 installed at the top and bottom of the inner wall of the storage tank 4, and piston assemblies disposed inside the first reaction unit 2 and the second reaction unit 3, and the reaction vessel 1 providing the necessary environmental conditions for the chemical reaction, such as temperature and pressure;

[0029] A support plate 13 is provided on one side of the reactor 1, and a support plate 14 is provided on one side of the support plate 13. A connecting plate 15 is installed between the support plate 14 and the reactor 1. A rotating component and a rolling component are provided between the support plate 13 and the support plate 14.

[0030] Furthermore, the piston assembly includes an electric telescopic rod 7 and a piston plate 8. The electric telescopic rod 7 is installed inside the reactor 1, and the output end of the electric telescopic rod 7 extends into the first reaction unit 2 and the second reaction unit 3. The piston plate 8 is installed at the output end of the electric telescopic rod 7.

[0031] The rotating assembly includes a servo motor 16 and a rotating shaft 17. The servo motor 16 is mounted on the outer wall of the support plate 13, and the rotating shaft 17 is connected to the output end of the servo motor 16. The end of the rotating shaft 17 away from the servo motor 16 is connected to the outer wall of the support plate 14.

[0032] The rolling assembly includes a ball groove 18, a ball 19, and a groove 20. The ball groove 18 is formed on the upper end face of the support plate 13, the ball 19 is installed in the ball groove 18, and the groove 20 is formed on the lower end face of the support plate 14. The ball 19 and the groove 20 are adapted to each other. When the support plate 13 and the support plate 14 rotate relative to each other, the ball 19 rotates on its own axis in the ball groove 18 and revolves around the ball in the groove 20. This motion converts the sliding friction between the support plate 13 and the support plate 14 into rolling friction, thereby effectively reducing friction and achieving a labor-saving effect.

[0033] The side walls of the first reaction unit 2 and the second reaction unit 3 are both connected to liquid inlet pipes 9, and the bottom of the reaction vessel 1 is connected to liquid outlet pipe 10.

[0034] The side wall of the storage tank 4 is connected to the feed pipe 11 and the gas guide pipe 12. The side walls of the liquid inlet pipe 9, the liquid outlet pipe 10, the feed pipe 11 and the gas guide pipe 12 are all equipped with corresponding valves. The gas guide pipe 12 facilitates the gas pressure balance of the reactor 1 and facilitates the discharge of liquid.

[0035] Through the above technical solution:

[0036] In use, solid raw materials are transported to storage tank 4 through feed pipe 11. Since filter screens 6 are installed at the top and bottom of the inner wall of storage tank 4, solid raw materials will be trapped in storage tank 4, realizing solid-liquid separation.

[0037] Activate the electric telescopic rod 7 to move the piston plate 8 in the first reaction unit 2 to the top of the first reaction unit 2, and simultaneously move the piston plate 8 in the second reaction unit 3 to the bottom of the second reaction unit 3. This operation ensures that the piston plate 8 is in its initial position, preparing for the subsequent addition of liquid raw materials.

[0038] Liquid raw materials are introduced into the first reaction unit 2 through the feed pipe 11. After the liquid raw materials are introduced, all valves are closed to ensure the sealing of the reactor 1. Then, the electric telescopic rod 7 and the servo motor 16 are started, causing the electric telescopic rod 7 on both sides to extend and retract alternately, pushing the piston plate 8 up and down within the reaction unit. Due to the movement of the piston plate 8, the liquid flows alternately between the first reaction unit 2 and the second reaction unit 3, realizing the dynamic circulation of the liquid within the reaction unit. It also comes into full contact with the solid raw materials through the storage tank 4, realizing the solid-liquid mixing reaction. The reciprocating motion of the piston plate 8 not only promotes the flow of the liquid, but also enhances the uniformity of the solid-liquid mixing through the stirring effect, ensuring that the reactants are evenly distributed within the reaction system and avoiding the problem of incomplete local reaction. The servo motor 16 drives the support plate 14 and the reactor 1 to rotate through the rotating shaft 17. Through rotation, the materials in the reactor 1 are continuously redistributed under the action of centrifugal force, further enhancing the mixing effect and ensuring that the reaction proceeds fully. The centrifugal force also causes the reaction waste to move and accumulate towards the side wall of the reactor 1, thereby preventing the waste from accumulating near the liquid outlet end of the liquid outlet pipe 10. This design effectively ensures that the outlet path of the reaction liquid is unobstructed, ensuring that the liquid can be discharged from the outlet pipe 10 at a stable rate.

[0039] The alternating compression and circulation of the piston plate 8, combined with the rotational motion of the reactor 1, form a dynamic mixing system, which allows the liquid raw materials to fully contact the solid raw materials and avoids the problem of insufficient local reaction.

[0040] Open the valve on the liquid outlet pipe 10 to allow the reacted liquid to drain smoothly from the storage tank 4. Since filters 6 are installed at the top and bottom of the inner wall of the storage tank 4, the liquid can flow out quickly, while solid residue is retained within the storage tank 4, preventing it from being discharged with the liquid, thus achieving solid-liquid separation. Finally, open the bottom cover 5 of the reactor 1, remove the filters 6, and directly remove the solid residue from the storage tank 4. This design, by installing filters 6 in the storage tank 4, enables rapid liquid discharge after the reaction and effective retention of solid residue, avoiding the additional steps such as filtration and centrifugation required in traditional solid-liquid separation. This method simplifies the operation process, reduces manual intervention and equipment requirements, improves separation efficiency and operational safety, while reducing equipment costs and maintenance difficulty, making the entire reaction process more efficient, convenient, and safe.

[0041] If solid raw materials need to be added midway, the reaction solution should be drained through the liquid outlet pipe 10 before adding the new solid raw materials. Then, continue to add solid and liquid raw materials separately according to the above steps to ensure the continuity and stability of the reaction process.

[0042] 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.
