Description

Technical Field

[0001] This utility model relates to the field of hydrogenation catalyst technology, and in particular to a multi-layer sieving device for hydrogenation catalysts. Background Technology

[0002] Hydrogenation catalysts are used to catalyze hydrogenation reactions, primarily in the petrochemical, chemical, and pharmaceutical industries. They typically consist of metals, oxides, and sulfides, and can promote hydrogenation reactions under high temperature and pressure, converting unsaturated compounds into saturated compounds. During the processing of hydrogenation catalysts, the particles need to be sieved to separate them into different sizes. Sieving is generally done in a multi-layered, vertical manner. However, some hydrogenation catalyst particles, after passing through the first, second, and third filters, experience repeated collisions with the meshes of multiple filters as they fall vertically, leading to particle breakage and affecting the quality of the hydrogenation catalyst particles. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that lead to the breakage of hydrogenation catalyst particles, thus affecting the quality of the hydrogenation catalyst particles, and to propose a multi-layer screening device for hydrogenation catalysts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-layer sieving device for hydrogenation catalyst is designed, including a base, on which two side plates are fixedly and inclinedly connected. Multiple filter plates are connected between the two side plates by a connecting mechanism. The mesh size of the multiple filter plates increases sequentially from top to bottom. A supporting step is fixedly connected to the base, and multiple collection boxes are placed on the supporting step. The multiple collection boxes are located directly below the multiple filter plates. Collection covers are fixedly connected to the ends of the two side plates.

[0006] Preferably, the connecting mechanism includes a connecting rib, and the connecting rib is fixedly connected to each of the plurality of filter plates. Limiting grooves are formed on the inner sides of the two side plates, and the connecting rib is located in the limiting groove.

[0007] Preferably, the collection cover is provided with a discharge valve.

[0008] Preferably, each of the two side plates is rotatably connected to a stop by a pin, and the two stopes abut against the connecting edge respectively.

[0009] Preferably, a housing is connected to the base via a support mechanism, a push plate is abutted inside the housing, a telescopic rod is fixedly connected to the push plate, and the telescopic rod is fixedly connected to the housing.

[0010] Preferably, the support mechanism includes a connecting cylinder, which is fixedly connected to the base. A column abuts against the bottom wall of the connecting cylinder, and the column is fixedly connected to the housing. The outer walls on both sides of the housing abut against the two side plates respectively.

[0011] Preferably, the telescopic rod is an electric telescopic rod.

[0012] The present invention proposes a multi-layer sieving device for hydrogenation catalysts, which has the following advantages: by using multiple filter plates that are tilted and laid flat, the hydrogenation catalyst only needs to pass through the filter holes once during sieving, thereby reducing the collision between the hydrogenation catalyst and the mesh, thus reducing the possibility of breakage of the hydrogenation catalyst during sieving, and thus improving the quality of the hydrogenation catalyst particles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4A multi-layer screening device for hydrogenation catalysts includes a base 1, on which two side plates 7 are fixedly and inclinedly connected. Multiple filter plates 10 are connected between the two side plates 7 by a connecting mechanism. The mesh size of the multiple filter plates 10 increases sequentially from top to bottom to screen hydrogenation catalysts of different sizes.

[0020] A support step 11 is fixedly connected to the base 1, and multiple collection boxes 12 are placed on the support step 11. The multiple collection boxes 12 are located directly below multiple filter plates 10. Collection covers 8 are fixedly connected to the ends of the two side plates 7. By using multiple filter plates 10 to be tilted and spread out, the hydrogenation catalyst only needs to pass through the filter holes once during screening, thereby reducing the collision between the hydrogenation catalyst and the mesh, so as to reduce the breakage of the hydrogenation catalyst during screening, which is beneficial to improving the quality of the hydrogenation catalyst particles.

[0021] During the screening process, the hydrogenation catalyst particles roll down from the top filter plate 10. The smallest particles will first pass through the first filter plate 10 and enter the first collection box 12. Those that do not pass through continue to roll. Medium-sized particles pass through the second filter plate 10 and enter the second collection box 12. Larger particles continue to roll, pass through the third filter plate 10, and enter the third collection box 12, thus completing the screening. Finally, the remaining large particles enter the collection hood 8.

[0022] Example 2: Refer to Figure 1-4 As another preferred embodiment of the present invention, based on embodiment 1, the connecting mechanism includes a connecting ridge 13. The connecting ridge 13 is fixedly connected to multiple filter plates 10. Limiting grooves are opened on the inner sides of the two side plates 7. The connecting ridge 13 is located in the limiting groove. The limiting groove and the connecting ridge 13 play a supporting and limiting role for the filter plate 10. At the same time, when the filter plate 10 needs to be replaced, the filter plate 10 can be removed by disengaging the connecting ridge 13 from the limiting groove.

[0023] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 2, two side plates 7 are rotatably connected with stop blocks 14 by pins. The two stop blocks 14 abut against the connecting ridges 13 respectively. Since gaps are easily generated between the filter plates 10, the uppermost filter plate 10 is abutted and limited by the stop blocks 14 abutting against the connecting ridges 13. The limiting groove is a blind groove, which avoids the situation where gaps are generated when the filter plates 10 move.

[0024] Example 4: Reference Figure 1-3As another preferred embodiment of this utility model, based on embodiment 3, a housing 4 is connected to the base 1 through a support mechanism. A push plate 5 is abutted inside the housing 4. A telescopic rod 6 is fixedly connected to the push plate 5. The telescopic rod 6 is an electric telescopic rod. The telescopic rod 6 is fixedly connected to the housing 4. By pouring hydrogenation catalyst particles into the housing 4, the telescopic rod 6 extends and drives the push plate 5 to move, pushing the hydrogenation catalyst particles into the filter plate 10.

[0025] The support mechanism includes a connecting cylinder 2, which is fixedly connected to the base 1. A column 3 abuts against the bottom wall of the connecting cylinder 2, and the column 3 is fixedly connected to the housing 4. The outer walls on both sides of the housing 4 abut against two side plates 7, respectively. The connecting cylinder 2 and the column 3 provide support for the housing 4, allowing the column 3 to be detached from the connecting cylinder 2 and the housing 4 to be disassembled, thus avoiding obstruction when replacing the filter plate 10.

[0026] A discharge valve 9 is connected to the collection hood 8 to discharge the hydrogenation catalyst particles that enter the collection hood.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
