Description

Technical Field

[0001] This invention relates to the field of chemical technology, specifically to a processing device for recycling 1,4-butenediol reaction catalyst. Background Technology

[0002] The reaction catalysts for 1,4-butenediol are mostly bimetallic catalysts. Using macroporous, low-surface-area α-alumina as a support, nickel chloride hexahydrate as a nickel source, and hydrazine hydrate as a reducing agent, a reduction bimetallic catalyst with a Pd / Ni / NiO / a-Al2O3 structure—1%Pd1%Ni / a-Al2O3(CR)—was synthesized and prepared. It exhibits high activity and high selectivity at room temperature and pressure.

[0003] However, after the catalytic reaction, the bimetallic catalyst has a large amount of substrate and product attached to the pores, which leads to a change in the adsorption strength of the bimetallic alloy due to the change in the electronic state of the metal, and also leads to a decrease in the selectivity of butene glycol.

[0004] To reduce costs, catalysts are often reused, which requires processing to remove substrates and products adhering to the catalyst pores. Existing processing methods usually involve washing the catalyst with water, but this method is relatively simple and, due to the small pores of the catalyst, it is difficult to ensure that the adhering substances inside the pores are completely removed. Summary of the Invention

[0005] The purpose of this invention is to provide a processing device for recycling 1,4-butenediol reaction catalysts, in order to solve the problems mentioned in the background art.

[0034] 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.

[0035] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0036] Please see Figures 1-9 In this embodiment of the invention, a processing device for recycling 1,4-butenediol reaction catalyst includes a base 1 and a frame 2 fixedly mounted on the base 1, and further includes:

[0037] A cylinder 3 is rotatably mounted on the frame 2 for holding the catalyst to be processed. The bottom of the cylinder 3 is a conductive structure. The rotating shaft of the cylinder 3 is connected to a speed transmission mechanism mounted on the top of the frame 2. The speed transmission mechanism is used to drive the cylinder 3 to rotate and is connected to a threaded drive mechanism mounted on the frame 2.

[0038] Two nozzles 29 are movably mounted on the base 1 for pumping water into the cylinder 3 to impact the catalyst inside the cylinder 3. The nozzles 29 are connected to a reciprocating drive mechanism mounted on the base 1. The reciprocating drive mechanism can drive the nozzles 29 to reciprocate along the axial direction of the cylinder 3 and is connected to the threaded drive mechanism.

[0039] The disc 4 is movably mounted on the base 1 and adapted to the cylinder 3, and is connected to the elastic fitting mechanism mounted on the base 1. The elastic fitting mechanism cooperates with the threaded drive mechanism. When the nozzle 29 stops pumping water, the speed transmission mechanism increases the rotation speed of the cylinder 3, and the elastic fitting mechanism is triggered, driving the disc 4 to move intermittently toward the inside of the cylinder 3.

[0040] When in operation, the threaded drive mechanism works, which drives the cylinder 3 to rotate through the speed transmission mechanism. At the same time, the threaded drive mechanism drives the reciprocating drive mechanism to move, and the reciprocating drive mechanism drives the nozzle 29 to move back and forth along the axial direction of the cylinder 3. This allows the water pumped out by the two nozzles 29 to have a strong convective flushing effect on the catalyst inside the cylinder 3, injecting water into the pores of the catalyst to wash away the substrate and products attached to the pores of the catalyst.

[0041] Subsequently, the nozzle 29 stops pumping water, and the speed transmission mechanism cooperates with the threaded drive mechanism to improve the transmission efficiency of the cylinder 3, thereby increasing the rotational speed of the cylinder 3. This allows the water injected into the pores to be removed from the pores by centrifugation, thus removing the adhering substances in the pores. At the same time, the elastic fitting mechanism is triggered, causing the disc 4 to move intermittently toward the inside of the cylinder 3, which has a certain squeezing effect on the catalyst inside the cylinder 3 and effectively promotes the removal of adhering substances in the catalyst pores, thereby improving the treatment effect on the catalyst.

[0042] In summary, this device employs a combination of strong convection flushing and centrifugal treatment to force water into the pores and then removes the water from the pores through centrifugation, thereby carrying away any attached substances. Furthermore, the coordinated operation of various mechanisms and structures results in high treatment efficiency and better treatment effect, making it suitable for widespread use.

[0043] Please refer to it again. Figure 1 and Figure 8 The threaded drive mechanism includes a lead screw 14 rotatably mounted on the frame 2, a threaded sleeve 39 sleeved on and threadedly connected to the lead screw 14, and a drive motor 13 mounted on the side of the frame 2. One end of the lead screw 14 is connected to the output end of the drive motor 13. The lead screw 14 is connected to both the speed transmission mechanism and the reciprocating drive mechanism. The threaded sleeve 39 is also fixedly connected to a guide sleeve 40, which is slidably connected to a crossbar 15 fixed on the frame 2.

[0044] It should be noted that, in order to facilitate the next use of the device, each component needs to be reset after processing. Therefore, the drive motor 13 should be a servo motor with bidirectional drive at the output end. This application does not make specific limitations on its specific model, and it can be selected according to actual needs.

[0045] Please refer to it again. Figure 1 , Figure 4 , Figure 6 as well as Figure 7The transmission mechanism includes a transverse structure mounted on the top of the frame 2 and a sliding fitting assembly connecting the transverse structure, the sliding fitting assembly being connected to the lead screw 14. The transverse structure includes a guide rail 19 fixedly mounted on the top of the frame 2 and a mounting seat 20 slidably fitted onto the guide rail 19. A second gear 22 and a third gear 23 are rotatably mounted at both ends of the mounting seat 20. The mounting seat 20 is connected to a driven structure mounted on the frame 2, the driven structure engaging with the threaded sleeve 39. The rotation shafts of the second gear 22 and the third gear 23 are connected to the sliding fitting assembly. A first gear 21 is fixed on the rotation shaft of the cylinder 3, engaging with the second gear 22 and the third gear 23. The size of the third gear 23 is larger than the size of the second gear 22.

[0046] The sliding fitting assembly includes a rotating shaft 16 rotatably mounted on the top of the frame 2 and a sleeve 17 rotatably mounted on the mounting base 20. The sleeve 17 is slidably fitted with the rotating shaft 16 through a limiting structure, and the rotating shaft 16 is connected to the lead screw 14 through a first transmission belt 18. The sleeve 17 is connected to the rotating shafts of the second gear 22 and the third gear 23 through a first bevel gear set 24 and a second bevel gear set 25, respectively.

[0047] In detail, the first bevel gear set 24 includes a first bevel gear fixedly mounted on the sleeve 17 and a second bevel gear fixedly mounted coaxially with the second gear 22, wherein the second bevel gear meshes with the first bevel gear;

[0048] Similarly, the second bevel gear set 25 includes a third bevel gear fixedly mounted on the sleeve 17 and a fourth bevel gear fixedly mounted coaxially with the third gear 23, wherein the fourth bevel gear meshes with the third bevel gear.

[0049] Secondly, the limiting structure includes two strip-shaped protrusions formed on the outer wall of the rotating shaft 16 and two strip-shaped grooves provided on the inner wall of the sleeve 17. The strip-shaped grooves are adapted to the strip-shaped protrusions, and both are parallel to the central axis of the rotating shaft 16 and the sleeve 17.

[0050] Please refer to it again. Figure 8The driven structure includes a transmission plate 26 slidably mounted on the frame 2 and a connecting rod 27 connecting the transmission plate 26 and the mounting base 20. The two ends of the connecting rod 27 are hinged to the transmission plate 26 and the mounting base 20, respectively. The transmission plate 26 has a groove, and a drive column 3901 is fixed between the threaded sleeve 39 and the guide sleeve 40. The drive column 3901 extends into the groove and is slidably connected to the transmission plate 26. The groove includes a first straight section 2601, an inclined section 2602, and a second straight section 2603 connected together.

[0051] When the threaded sleeve 39 moves by engaging with the lead screw 14, the threaded sleeve 39 will drive the drive column 3901 to move together. When the drive column 3901 slides in the first straight section 2601, the transmission plate 26 does not slide on the frame 2. This process is the water filling process. The second gear 22 is in a meshing state with the first gear 21, and the third gear 23 is in a disengaged state with the first gear 21.

[0052] When the drive column 3901 slides in the inclined section 2602, it will slide into contact with the transmission plate 26, causing the transmission plate 26 to move downward on the frame 2. Correspondingly, the transmission plate 26 drives the mounting base 20 to slide along the guide rail 19 via the connecting rod 27. Then, the sleeve 17, the second gear 22, and the third gear 23 move together with the mounting base 20 until the second gear 22 disengages from the first gear 21 and the third gear 23 meshes with the first gear 21. Since the size of the third gear 23 is larger than the size of the second gear 22, the rotational speed of the cylinder 3 is increased to facilitate subsequent centrifugal processing (i.e., the process of the drive column 3901 sliding in the second straight section 2603).

[0053] Please refer to it again. Figure 1 and Figure 9The elastic fitting mechanism includes a vertical plate 6 fixedly mounted on the base 1 and a sleeve plate 7 slidably fitted with the vertical plate 6. The disc 4 is fixed to the end of the sleeve plate 7 away from the base 1. Multiple sets of elastic elements are provided between the vertical plate 6 and the sleeve plate 7. The elastic elements include a column 9 fixed to the vertical plate 6, a protrusion 8 fixed to the sleeve plate 7 and slidably connected to the column 9, and a columnar spring 11 sleeved on the column 9. One end of the columnar spring 11 is connected to the protrusion 8, and the other end is connected to a boss 12 fixed to the column 9. The sleeve plate 7 is also fixedly connected to a driven plate 5. The guide sleeve 40 is connected to a pulley 38, which abuts against the driven plate 5. The end of the driven plate 5 away from the sleeve plate 7 forms a connected straight portion 501 and a stepped portion 502.

[0054] It should be noted that the straight portion 501 corresponds to the first straight section 2601 and the inclined section 2602, and the stepped portion 502 corresponds to the second straight section 2603. When the driving column 3901 slides along the second straight section 2603, the pulley 38 rolls along the stepped portion 502, thereby causing the driven plate 5 to give way. Correspondingly, the driven plate 5 drives the sleeve plate 7 and the disc 4 to rise, and the columnar spring 11 is compressed. During the centrifugal treatment, the disc 4 can exert a certain squeezing effect on the catalyst in the cylinder 3, which effectively promotes the removal of the adhering substances in the catalyst pores and improves the treatment effect of the catalyst.

[0055] Please refer to it again. Figure 2 , Figure 5 as well as Figure 6 The base 1 is also fixed with a vertical plate 30, and a slider 31 is slidably mounted on the vertical plate 30. The nozzle 29 is fixed to the slider 31 via an assembly plate 28, and two limiting strips 32 are fixed to the side of the slider 31 away from the assembly plate 28, with a gap reserved between the two limiting strips 32. The reciprocating drive mechanism includes two drive wheels 33 rotatably mounted on the vertical plate 30, a connecting member 34 connecting the two drive wheels 33, and a column 10 provided on the connecting member 34. The column 10 extends into the gap and is slidably connected to the two limiting strips 32. The connecting member 34 is in rolling engagement with the two drive wheels 33. The rotation shaft of one of the drive wheels 33 is connected to a transmission shaft 36 rotatably mounted on the frame 2 via a second transmission belt 35. The transmission shaft 36 is connected to the lead screw 14 via a third bevel gear set 37.

[0056] In detail, the third bevel gear set 37 includes a sixth bevel gear fixedly installed at the end of the transmission shaft 36 and a fifth bevel gear fixedly installed at the end of the lead screw 14 away from the drive motor 13, and the fifth bevel gear meshes with the sixth bevel gear.

[0057] When the drive motor 13 drives the lead screw 14 to rotate, the lead screw 14 can drive the transmission shaft 36 to rotate through the third bevel gear set 37. The transmission shaft 36 then drives the drive wheel 33 to rotate through the second transmission belt 35, causing the connector 34 to drive the column 10 to move. The movement trajectory of the column 10 is consistent with the closed shape formed by the connector 34. The column 10 also causes the slider 31 to slide up and down on the vertical plate 30 through the two limiting plates 32. The nozzle 29 performs a reciprocating motion along the axial direction of the cylinder 3 to ensure the comprehensive water filling of the catalyst.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
