Description

Technical Field

[0001] This utility model relates to the field of catalyst preparation technology, specifically to a solid-liquid separation device for catalyst preparation. Background Technology

[0002] A catalyst preparation device is a specialized equipment for producing catalysts used in chemical reactions. In the preparation process, the raw materials are first precisely proportioned and mixed to form a catalyst precursor. Subsequently, the precursor needs to be dried to remove moisture, and then calcined at high temperatures to promote the formation of the active phase of the catalyst, thereby obtaining the finished catalyst with the desired physicochemical properties.

[0003] Chinese patent CN220214895U discloses a catalyst preparation device. By installing a mixing and stirring assembly inside the preparation cylinder, the forward rotation of the motor causes the rotating shaft to rotate clockwise during the reaction and mixing of the raw materials inside the cylinder. This, in turn, causes the connecting rod to drive the side stirring blades to rotate synchronously. By setting the tilt angle of the stirring blades relative to the top of the connecting rod between 30 and 60 degrees, the mixing effect is improved, enhancing the uniformity of the material mixture. Furthermore, during stirring, the scraper rod rotates synchronously against the inner wall of the preparation cylinder, preventing the raw materials from adhering to the inner wall of the cylinder. The first and second connecting blocks are connected to the rotating shaft on one side by anti-loosening bolts, which facilitates disassembly and cleaning of the mixing and stirring components. However, the above-mentioned device is difficult to separate the catalyst into solid and liquid components during use, which increases the processing time, prolongs the cycle of the entire preparation process, and reduces production efficiency. Poor solid-liquid separation will result in a large amount of liquid residue in the finished catalyst, affecting the purity and performance stability of the final product. At the same time, incomplete solid-liquid separation will lead to the overuse of raw materials, requiring additional water or solvents to dilute or clean the solids, which not only wastes resources but also increases the cost of waste liquid treatment.

[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 refer to Figure 1 A solid-liquid separation device for catalyst preparation includes: a preparation cylinder 1, a feed hopper 4 installed on the top of the preparation cylinder 1, and a plurality of uniformly distributed support columns fixed at the bottom of the preparation cylinder 1.

[0029] Please refer to Figure 2 , Figure 3 and Figure 4Separation mechanism 2, located inside preparation cylinder 1, is used to separate the catalyst from the liquid during the preparation process. Separation mechanism 2 includes a first sieve plate 22 and a second sieve plate 23 installed inside preparation cylinder 1, a stirring assembly, and a pushing assembly. The stirring assembly is located on top of the first sieve plate 22 and is used to stir the catalyst after the first separation. The pushing assembly is located between the first sieve plate 22 and the second sieve plate 23 and is used to push the catalyst after the second separation. The stirring assembly includes multiple rotating shafts 28 disposed inside preparation cylinder 1. Multiple flexible stirring plates 212 are fixed to the outer walls of each rotating shaft 28, and the multiple flexible stirring plates 212 are evenly matched with the first sieve plate 22. A driving assembly for driving the multiple rotating shafts 28 is provided on one side inside preparation cylinder 1. The driving assembly includes a drive motor 210 fixed to one side of preparation cylinder 1 and a transmission shaft 2 connected to the axis of the multiple rotating shafts 28. 9. Multiple drive shafts 29 extend to one side of the preparation cylinder 1 and are equipped with wheel discs. A belt 211 is installed between the multiple wheel discs. The output end of the drive motor 210 is connected to one of the drive shafts 29. The pushing assembly includes a fixed groove and two limiting grooves opened on both sides inside the preparation cylinder 1. A fixed rod 25 is installed inside each of the two limiting grooves. A limiting plate is sleeved on the outer wall of each of the two fixed rods 25. A threaded rod 26 is installed inside the fixed groove. A servo motor 27 is fixed on one side of the preparation cylinder 1. The output end of the servo motor 27 is connected to the threaded rod 26. A threaded block is screwed onto the outer wall of the threaded rod 26. A filter plate 24 is installed between the threaded block and the two limiting plates. The filter plate 24 cooperates with the first screening plate 22 and the second screening plate 23. Two discharge ports are opened on one side of the preparation cylinder 1. A closing plate 21 is inserted into the interior of each of the two discharge ports, and the two discharge ports correspond to the first screening plate 22 and the second screening plate 23, respectively.

[0030] After the catalyst is separated by the first sieve plate 22, larger solids remain on the top of the first sieve plate 22. The drive motor 210 drives one of the drive shafts 29 to rotate, which in turn drives the wheel to rotate synchronously. Through the belt 211, multiple wheel discs drive multiple drive shafts 29 to rotate, which in turn drives multiple rotating shafts 28 to rotate. The rotation of the rotating shafts 28 drives the stirring plate 212 to rotate, thus effectively removing larger solid particles. The agitation of the filter plate 23 allows smaller particles mixed with larger solid particles to be separated, preventing poor separation efficiency. The second screening plate 23 keeps smaller particles on top, and the servo motor 27 drives the threaded rod 26 to rotate. The rotation of the threaded rod 26 causes the threaded block to move horizontally on its outer wall. The movement of the threaded block drives the filter plate 24 to move, which in turn agitates the smaller particles, thereby further separating the liquid mixed with them and greatly improving the separation efficiency of the device.

[0031] Please also refer to... Figure 5 and Figure 6 An observation mechanism 3 is provided on one side of the preparation cylinder 1 to observe the liquid accumulated at its bottom. The observation mechanism 3 includes a flow port 31 opened at the bottom of the preparation cylinder 1. A flow groove is opened on one side of the preparation cylinder 1, which is connected to the flow port 31. A connecting pipe 32 is installed on one side of the flow groove. A drain pipe 33 is connected to the bottom of the connecting pipe 32. A one-way valve is installed inside the drain pipe 33. A reinforcing sleeve 34 is fixed to the outer wall of the connecting pipe 32. The reinforcing sleeve 34 is connected to the preparation cylinder 1. A floating assembly for easy observation of the liquid level is provided inside the connecting pipe 32. The floating assembly includes a float 35 set inside the connecting pipe 32. An observation rod 36 is fixed to the top of the float 35. A sealing plate 37 is installed on the top of the connecting pipe 32. The observation rod 36 is inserted into the sealing plate 37. A pointing sleeve 38 is fixed to the top of the sealing plate 37. The pointing sleeve 38 corresponds to the observation rod 36.

[0032] When the separated liquid flows into the bottom of the preparation cylinder 1, it enters the flow channel through the flow port 31. As the liquid continuously increases, it flows through the flow channel and then into the connecting pipe 32. When the liquid enters the connecting pipe 32, it causes the float 35 to move upward. The upward movement of the float 35 causes the observation rod 36 to move upward. The upward movement of the observation rod 36 changes the position between it and the pointing sleeve 38, thus facilitating the user to observe the liquid level inside the preparation cylinder 1. The opening and closing of the drain pipe 33 is controlled by a one-way valve, allowing the drain pipe 33 to discharge the liquid inside the preparation cylinder 1.
