Description

Technical Field

[0001] This utility model relates to the field of separation technology, and more specifically, to a p-aminophenol catalyst separator. Background Technology

[0002] The main purpose of a filtration system for p-aminophenol catalyst separators is to separate the catalyst from the reaction liquid and recover the catalyst for reuse. Its primary function is to improve production efficiency: in the production of p-aminophenol, the catalyst is a crucial reaction promoter. Effective filtration ensures the complete separation of the catalyst from the reaction liquid, preventing interference or loss in subsequent processes.

[0003] Among existing published documents, patent publication number CN117510348A discloses a method for the continuous catalytic hydrogenation of p-nitrophenol to prepare p-aminophenol. This technology involves heating and pressurizing the circulating material in a buffer tank to the reaction conditions; then adding a reaction solution composed of p-nitrophenol and a solvent to the circulating pipeline after the separator. The p-nitrophenol and hydrogen in the reaction solution undergo a hydrogenation reaction as they pass through a Venturi reactor. After separation and purification, the target product, p-aminophenol, is obtained. This invention achieves a highly efficient continuous catalytic hydrogenation reaction, with a simple process, low cost, high production efficiency, high product yield, and is safe and environmentally friendly; however, this patent has the following drawbacks. The p-aminophenol catalyst needs to be separated by a separator to remove some solid impurities. During the separation process, liquid is fed into the inlet pipe and discharged from the outlet pipe. However, when the flow rate of the inlet pipe is high, it is difficult to achieve simultaneous discharge of large flow rates, which leads to low separation efficiency of the p-aminophenol catalyst. Therefore, a p-aminophenol catalyst separator is provided. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a p-aminophenol catalyst separator, comprising a separation shell, a feed pipe, and a discharge pipe. The feed pipe is fixedly connected to one side of the outer wall of the separation shell, and the discharge pipe is fixedly connected to the other side of the outer wall of the separation shell. A switching and drainage assembly is installed at the bottom of the separation shell. The switching and drainage assembly includes a geared motor fixedly installed at the bottom of the separation shell. The outer wall of the geared motor is provided with multiple drainage pipes, all of which are fixedly connected to the separation shell. A rotating shaft is fixedly installed at the output end of the geared motor, and a sealing hole gasket is fixedly connected to the outer wall of the rotating shaft. A sealing hole plate is adhered to the lower surface of the sealing hole gasket, and multiple drainage holes are opened inside the sealing hole gasket.

[0005] Preferably, the plurality of drain holes are arranged in a circular, equidistant ring, and the cross-sectional shape of the drain holes is circular; the sealing gasket is slidably connected to the drain pipe. The plurality of drain pipes are arranged in a circular, equidistant ring, and the cross-sectional shape of each drain pipe is annular. Rotating rings are fixedly connected to the lower surface of the sealing plate and the upper surface of the sealing gasket. Both rotating rings are fixedly connected to a rotating shaft. An inner shell is fixedly installed on the inner wall of the separating shell, and the separating filter screen is inserted into the inner shell. A top cover is fixedly installed at the top of the separating shell, a washer is adhered to the upper surface of the top cover, a locking cover is installed on the upper surface of the washer, and multiple locking bolts are inserted into the inside of the locking cover. The top cover and the locking cover are fixedly connected by multiple locking bolts.

[0006] In use, this technology uses a separation filter inside the inner shell to filter and separate the p-aminophenol catalyst. When a large amount of p-aminophenol catalyst enters the feed pipe, the high flow rate of the catalyst drives the rotating shaft to rotate via a geared motor. The rotating shaft drives the sealing gasket to rotate, and the rotating shaft drives two rotating rings to rotate synchronously. The sealing gasket rotates on the drain pipe. When the drain hole is aligned with the bottom of the drain pipe, the p-aminophenol catalyst inside the inner shell will be quickly discharged through multiple drain pipes.

[0007] Preferably, a support and flow guiding assembly is installed on the outer wall of the separating shell near its bottom end; the support and flow guiding assembly includes a mounting ring fixedly installed on the outer wall of the separating shell near its bottom end, a plurality of support rings fixedly connected to the lower surface of the mounting ring, a reinforcing column fixedly connected to the inner wall of the support ring, a flow guide shroud installed at the bottom end of the reinforcing column, and a plurality of reinforcing columns fixedly connected to the flow guide shroud. The plurality of reinforcing columns are arranged in a circular ring at equal intervals, and the diameter of the inner wall of the top end of the flow guide shroud is smaller than the diameter of the inner wall of its bottom end.

[0008] When this technology is used, the support rings support the reinforcing column, providing a stable reinforcing force. The efficiency of the p-aminophenol catalyst after separation by multiple drain pipes is also higher.

[0009] The technical effects and advantages of this utility model are as follows: 1. This utility model, by switching the drainage component, allows a high flow rate of p-aminophenol catalyst to enter the feed pipe when a large amount of p-aminophenol catalyst enters. The rotating shaft is driven by a geared motor, which in turn drives the sealing hole gasket to rotate. The sealing hole gasket and the sealing hole plate can rotate synchronously, and the drainage hole is aligned with the bottom of the drainage pipe. This enables rapid drainage of multiple p-aminophenol catalysts, achieving high-flow synchronous drainage and significantly improving the separation efficiency of p-aminophenol catalyst. 2. This utility model adopts an installation ring to support multiple support rings, which in turn support the reinforcing column, providing stable reinforcement force to the reinforcing column and reinforcement support force to the guide shroud. In this way, the efficiency of the p-aminophenol catalyst after separation by multiple discharge pipes is higher. Attached Figure Description

[0016] 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.

[0017] As attached Figure 1 - Appendix Figure 5 The diagram shows a p-aminophenol catalyst separator, which is equipped with a switching drainage component. The switching drainage component enables rapid discharge of multiple p-aminophenol catalysts, allowing for simultaneous discharge at high flow rates and significantly improving the separation efficiency of the p-aminophenol catalyst. The specific structure of the switching drainage component is as follows.

[0018] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, the feed pipe 2 is fixedly connected to one side of the outer wall of the separation shell 1, and the discharge pipe 3 is fixedly connected to the other side of the outer wall of the separation shell 1. A switching drainage assembly is installed at the bottom of the separation shell 1. The switching drainage assembly includes a reduction motor 5 fixedly installed at the bottom of the separation shell 1. The outer wall of the reduction motor 5 is provided with multiple drainage pipes 6, and all multiple drainage pipes 6 are fixedly connected to the separation shell 1. A rotating shaft 7 is fixedly installed at the output end of the reduction motor 5, and a sealing hole gasket 8 is fixedly connected to the outer wall of the rotating shaft 7. A sealing hole plate 9 is bonded to the lower surface of the sealing hole gasket 8, and multiple drainage holes 10 are opened inside the sealing hole gasket 8. The multiple drainage holes 10 are arranged in a circular ring at equal intervals, and the cross-sectional shape of the drainage holes 10 is circular. The multiple drainage pipes 6 are arranged in a circular ring at equal intervals, and the cross-sectional shape of each drainage pipe 6 is circular.

[0019] In this technical solution, as shown in the appendix Figure 2 - Appendix Figure 4 As shown, an inner shell 12 is fixedly installed on the inner wall of the separation shell 1. The separation filter 4 is inserted into the inner shell 12 to allow the p-aminophenol catalyst to be separated to enter the interior of the separation shell 1 through the feed pipe 2 and then into the interior of the inner shell 12, increasing the stability of the inner shell 12. A top cover 13 is fixedly installed at the top of the separation shell 1. A gasket 14 is bonded to the upper surface of the top cover 13. A locking cover 15 is installed on the upper surface of the gasket 14. Multiple locking bolts 16 are inserted into the inside of the locking cover 15. The top cover 13 and the locking cover 15 are fixedly connected by multiple locking bolts 16, so that the locking cover 15 presses against the upper surface of the gasket 14, and the gasket 14 presses against the upper surface of the top cover 13. The separation shell 1 supports the top cover 13, and the multiple locking bolts 16 can firmly seal and lock the locking cover 15 and the top cover 13.

[0020] In use, the p-aminophenol catalyst separator of this technology operates by locking the cover 15 onto the upper surface of the gasket 14, which in turn presses against the upper surface of the top cover 13. The top cover 13 is supported by the outer shell 1, and multiple locking bolts 16 ensure a tight seal between the locking cover 15 and the top cover 13. The p-aminophenol catalyst to be separated is then fed into the inner shell 1 through the feed pipe 2, and then into the inner shell 12. The inner shell 12's filter screen 4 filters and separates the p-aminophenol catalyst, which is then discharged through the discharge pipe 3. When a large amount of p-aminophenol catalyst enters the feed pipe 2, the high flow rate of the p-aminophenol catalyst drives the rotating shaft 7 to rotate via the reduction motor 5. The rotating shaft 7 drives the sealing hole gasket 8 to rotate, and at the same time, the rotating shaft 7 drives the sealing hole plate 9 to rotate. The rotating shaft 7 will drive the two rotating rings 11 to rotate synchronously. The sealing hole gasket 8 and the sealing hole plate 9 can rotate synchronously, so the sealing hole gasket 8 rotates on the drain pipe 6. When the drain hole 10 is aligned with the bottom end of the drain pipe 6, the p-aminophenol catalyst inside the inner shell 12 will be quickly discharged down through multiple drain pipes 6, achieving rapid discharge of multiple p-aminophenol catalysts.

[0021] In this technical solution, as shown in the appendix Figure 5 As shown, a support and flow guiding assembly is installed on the outer wall of the separate housing 1 near its bottom end. The support and flow guiding assembly includes a mounting ring 17 fixedly installed on the outer wall of the separate housing 1 near its bottom end. Multiple support rings 18 are fixedly connected to the lower surface of the mounting ring 17. Reinforcing columns 19 are fixedly connected to the inner wall of the support rings 18. A flow guide shroud 20 is installed at the bottom end of each reinforcing column 19. All reinforcing columns 19 are fixedly connected to the flow guide shroud 20. The multiple reinforcing columns 19 are arranged in a circular, equidistant distribution. The diameter of the inner wall at the top end of the flow guide shroud 20 is smaller than the diameter of its inner wall at the bottom end.

[0022] In use, the p-aminophenol catalyst separator of this technology uses a separation shell 1 to support a mounting ring 17, which in turn supports multiple support rings 18. The support rings 18 support a reinforcing column 19, providing a stable reinforcing force to the reinforcing column 19. The reinforcing column 19 also supports a flow guide shroud 20, providing a reinforcing support force to the flow guide shroud 20. In this way, the p-aminophenol catalyst separated by multiple drain pipes 6 is discharged with higher efficiency.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.
