Description

Technical Field

[0001] This invention relates to the field of catalyst reaction technology, and more specifically to catalyst reaction vessels. Background Technology

[0002] Due to limitations in chemical conditions, the rate of chemical reactions is often relatively slow. In such cases, it is necessary to add a catalyst to increase the reaction rate. A catalyst is a substance whose mass and chemical properties do not change before and after the chemical reaction. It is widely used in industrial production. During the production of catalysts, various solid and liquid reactants are often put into a reaction vessel for reaction. The reaction vessel is equipped with a stirring rod to stir the reactants, thereby mixing the different reactants together.

[0003] However, when mixing multiple reactants in existing reactors, the traditional stirring rods tend to generate vortices during stirring, causing the reactants to flow radially, resulting in uneven mixing of the various reactants and a decrease in the mixing effect. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a catalyst reactor to solve the problems that have occurred in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a catalyst reactor, comprising a reactor body for catalyst reaction, wherein a rotating plate is provided inside the reactor body, and a cavity is formed inside the rotating plate. From left to right, a stirring shaft, a first screw, and a second screw are sequentially arranged inside the cavity. The bottom ends of the stirring shaft, the first screw, and the second screw extend through the rotating plate into the reactor body. Multiple stirring rods are fixedly arranged on the outer wall of the stirring shaft. A first annular plate is fixedly arranged inside the reactor body.

[0008] In a preferred embodiment, each transmission component includes two sprockets. The four sprockets are respectively mounted on the stirring shaft, the first screw, and the second screw. The sprockets on the stirring shaft and the first screw, as well as the sprockets on the first screw and the second screw, are connected by chains. The top ends of the stirring shaft, the first screw, and the second screw are all connected to the inner wall of the cavity through bearings. By using the sprockets and chains, the stirring shaft, the first screw, and the second screw are linked together. The rotation of the stirring shaft reduces the number of first motors required.

[0013] In a preferred embodiment, a controller is fixedly provided at the front end of the vessel body. The controller is connected to a solenoid valve, a hydraulic cylinder, a second motor, and a first motor, which facilitates the operation of the entire device by the operator.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention uses a first motor to drive a rotating plate, which in turn drives a stirring shaft, a first screw, and a second screw to rotate inside the reactor. The first gear on the stirring shaft meshes with the first tooth groove on the first ring plate and rotates on its own. The stirring rod on the stirring shaft rotates while making an eccentric motion. Simultaneously, driven by two transmission components, the first screw and the second screw rotate together with the stirring shaft, so that the catalyst reaction raw materials in the reactor continuously flow. Combined with the stirring rod, this greatly improves the mixing speed of the catalyst reaction raw materials. Furthermore, only one first motor is needed to drive the stirring shaft, the first screw, and the second screw to rotate simultaneously, which greatly reduces the operating cost of the device.

[0016] 2. The second gear is driven to rotate by the second motor. The second gear meshes with the second tooth groove on the second ring plate, thereby driving the vessel body to rotate on the support base. This causes the catalyst reaction material inside the vessel body to rotate. In conjunction with the stirring shaft, the first screw and the second screw, the mixing effect of the catalyst reaction material is further improved.

[0017] 3. By extending four hydraulic cylinders, the hydraulic cylinders push the third ring plate upward, causing the cover plate to move upward together, removing the stirring shaft, the first screw, and the second screw from the inside of the vessel. Then, the staff can remove the cover plate from the third ring plate as needed to clean the stirring shaft, the first screw, and the second screw. At the same time, they can loosen the multiple bolts between the sealing plate and the vessel to remove the sealing plate, making it easier to clean the inside of the vessel.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Refer to the instruction manual appendix Figure 1 , 2 3, 4 and 7, the present invention provides a catalyst reaction vessel, including a vessel body 1 for catalyst reaction, wherein a rotating plate 2 is provided inside the vessel body 1, and a cavity 3 is provided inside the rotating plate 2.

A plurality of stirring rods 7 are fixedly provided on the outer wall of the stirring shaft 4.

[0028] A first annular plate 8 is fixedly installed inside the vessel body 1. Multiple first toothed grooves 9 are machined on the inner wall surface of the first annular plate 8. A first gear 10 is sleeved on the outer wall of the stirring shaft 4. The side of the first gear 10 away from the first screw 5 meshes with the multiple first toothed grooves 9 on the first annular plate 8. Transmission assemblies are provided between the stirring shaft 4 and the first screw 5, and between the first screw 5 and the second screw 6. Both transmission assemblies are located inside the cavity 3. Each transmission assembly includes two sprockets 19, and the four sprockets 19 are respectively sleeved on the stirring shaft 4. The sprockets 19 on the stirring shaft 4, the first screw 5, and the second screw 6 are connected by chains 20. The top ends of the stirring shaft 4, the first screw 5, and the second screw 6 are all connected to the inner wall of the cavity 3 by bearings. The sprockets 19 and chains 20 are used to link the stirring shaft 4, the first screw 5, and the second screw 6 together. The rotation of the stirring shaft 4 reduces the number of first motors 16 required.

[0029] The top of the vessel body 1 is provided with a cover plate 11, and a lifting assembly is provided between the cover plate 11 and the vessel body 1. A driving assembly is fixedly provided on the cover plate 11. The driving assembly is connected to the top of the rotating plate 2. The driving assembly includes a first motor 16, which is fixed to the top of the cover plate 11. A connecting shaft 17 is fixedly provided at the bottom of the output shaft of the first motor 16. The bottom of the connecting shaft 17 is fixedly connected to the top of the rotating plate 2. The rotating plate 2 is driven to rotate by the first motor 16 without manual operation. A collar 18 is fixedly provided at the top of the rotating plate 2. The top of the collar 18 is connected to the inner wall of the cover plate 11 through a bearing. The collar 18 is used to increase the stability between the rotating plate and the cover plate 11.

[0030] The outer wall of the vessel body 1 is fitted with a support base 12, and the outer wall of the vessel body 1 is provided with a rotating component. A feeding pipe 13 is provided through the front side of the vessel body 1, and an outlet is opened at the bottom end of the vessel body 1. A sealing plate 14 is provided inside the outlet, and a discharge pipe 15 is provided through the bottom end of the sealing plate 14. Solenoid valves 32 are fixedly installed on both the discharge pipe 15 and the feeding pipe 13. Support legs are fixedly installed at the four corners of the bottom end of the support base 12 to increase the stability of the vessel body 1 during use. A controller 33 is fixedly installed at the front end of the vessel body 1. The controller 33 is connected to the solenoid valve 32 and the first motor 16 to facilitate the operation of the entire device by the operator.

[0031] In operation, the operator first feeds the catalyst reaction material into the vessel body 1 through the feed pipe 13. Then, the controller 33 starts the first motor 16. The first motor 16 drives the rotating plate 2 to rotate inside the vessel body 1 via the connecting shaft 17. When the rotating plate 2 rotates, it drives the stirring shaft 4, the first screw 5, and the second screw 6 to rotate inside the vessel body 1. The first gear 10 on the stirring shaft 4 meshes with multiple first tooth grooves 9 on the inner wall of the first ring plate 8 and rotates, thereby driving the stirring shaft 4 to rotate as well. The stirring rod 7 on the stirring shaft 4 rotates while making an eccentric motion, which fully stirs the catalyst reaction material inside the vessel body 1. At the same time, driven by the two sets of sprockets 19 and chains 20, the first screw 5 and the second screw 6 rotate together with the stirring shaft 4. The configuration is reversed. The first screw 5 conveys the catalyst reaction material located at the bottom of the inner cavity of the vessel body 1 upward, and the second screw 6 conveys the catalyst reaction material located at the top of the inner cavity of the vessel body 1 downward, so that the catalyst reaction material in the vessel body 1 flows continuously. With the rotation of the stirring rod 7 on the stirring shaft 4, the mixing speed of the catalyst reaction material is greatly improved. Moreover, only one first motor 16 is needed to drive the stirring shaft 4, the first screw 5 and the second screw 6 to rotate simultaneously, which greatly reduces the operating cost of the device. After the mixing reaction is completed, the solenoid valve 32 on the discharge pipe 15 is opened to discharge the material.

[0032] Refer to the instruction manual appendix Figure 1 , 2 5 and 6, the present invention provides a catalyst reactor, wherein the top end of the support base 12 is provided with a through hole 21, the reactor body 1 is disposed in the through hole 21, the inner wall of the through hole 21 is provided with an annular groove 22, and the rotating assembly includes a second annular plate 23, the second annular plate 23 being disposed in the annular groove 22. Inside, the outer wall of the second ring plate 23 is machined with multiple second toothed grooves 24. The second ring plate 23 is used to install the vessel body 1 in the through hole 21 to improve the stability of the vessel body 1 when rotating. An installation cavity 25 is opened on one side of the annular groove 22. A second gear 26 is provided in the installation cavity 25. One side of the second gear 26 meshes with the second toothed groove 24. A second motor 27 is fixedly installed at the bottom of the second gear 26. The second motor 27 is fixed inside the installation cavity 25. The bottom end of the installation cavity 25 extends to the bottom surface of the support base 12. The second motor 27 drives the second gear 26 to mesh with the multiple second toothed grooves 24, driving the vessel body 1 to rotate on the support base 12, improving the mixing effect of the catalyst reaction raw materials. The controller 33 is connected to the second motor 27.

[0033] When the catalyst reaction materials inside the vessel body 1 are stirred and mixed using the stirring shaft 4, the first screw 5, and the second screw 6, the controller 33 simultaneously starts the second motor 27. The second motor 27 drives the second gear 26 to rotate. The second gear 26 meshes with the second tooth groove 24 on the second ring plate 23, thereby driving the vessel body 1 to rotate on the support base 12, causing the catalyst reaction materials inside the vessel body 1 to rotate. This, in conjunction with the stirring shaft 4, the first screw 5, and the second screw 6, further improves the mixing effect of the catalyst reaction materials.

[0034] Refer to the instruction manual appendix Figure 1 , 2 5 and 7, the present invention provides a catalyst reactor, wherein the lifting assembly includes a third ring plate 28, and four evenly distributed hydraulic cylinders 29 are fixedly provided at the bottom end of the third ring plate 28. One side of each of the four hydraulic cylinders 29 is fixedly connected to the outer wall of the reactor body 1. The four hydraulic cylinders 29 are used to lift the cover plate 11, thereby improving the stability of the cover plate 11 when moving up and down. A plurality of inserts 30 are fixedly provided at the top end of the third ring plate 28. A plurality of slots 31 are opened on the bottom surface of the cover plate 11. The plurality of inserts 30 are respectively inserted into the plurality of slots 31. The cover plate 11 and the third ring plate 28 are connected together by the inserts 30 and the slots 31, which makes it easy for the operator to remove the cover plate 11 from the third ring plate 28. A plurality of bolts are threadedly connected to the bottom surface of the sealing plate 14. The sealing plate 14 is fixedly connected to the reactor body 1 by the bolts, which makes it easy to remove the sealing plate 14 and clean the inside of the reactor body 1. The controller 33 is connected to the hydraulic cylinders 29.

[0035] After use, the operator uses controller 33 to extend the four hydraulic cylinders 29. The hydraulic cylinders 29 push the third ring plate 28 upward, and the third ring plate 28 pushes the cover plate 11 upward, thereby removing the stirring shaft 4, the first screw 5, and the second screw 6 from the inside of the vessel body 1. Then, the operator can remove the cover plate 11 from the third ring plate 28 as needed to clean the stirring shaft 4, the first screw 5, and the second screw 6. At the same time, the operator can unscrew the multiple bolts between the sealing plate 14 and the vessel body 1 to remove the sealing plate 14, making it easier to clean the inside of the vessel body 1.
