Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical intermediates technology, and in particular to a dust removal device for palladium-carbon catalyst filter cartridges. Background Technology

[0002] Palladium on carbon (PAC) is a commonly used high-efficiency catalyst in pharmaceutical intermediates. It is made by loading palladium powder onto activated carbon and is mainly used for the catalytic hydrogenation of unsaturated hydrocarbons and nitro groups, debenzylation, and reduction of aromatic compounds. It features high hydrogenation reducing power, good selectivity, stable performance, low feed ratio, reusability, and easy recovery. To facilitate the recycling and recovery of PAC catalysts, they are often integrated into filter cartridges. However, during daily use, some dust and impurities accumulate on the sidewalls of the filter cartridges.

[0003] A dust removal device for a catalyst filter element, disclosed in CN221062039U, includes a base plate. Two sliding grooves are formed on the top right side of the base plate, and a dust removal mechanism is also located on the top right side of the base plate above the sliding grooves. A base is located on the top left side of the base plate, and a housing is located on the top of the base. A motor is detachably mounted on the inner bottom wall of the housing. The output end of the motor is locked with a lead screw via a coupling, and the other end of the lead screw is fixedly connected to the inner wall of the housing via a bearing. A connecting block is threaded onto the outer wall of the lead screw, and the right end of the connecting block extends out of the housing. This invention employs a mechanical cleaning method, resulting in higher efficiency, more ideal dust removal effect, improved filter element utilization, and better meeting actual production and processing needs.

[0004] However, the aforementioned dust removal devices still have certain shortcomings in actual use. In general, existing dust removal devices do not have built-in components for fixing the filter element in the dust collection cylinder. When the air jet box back-blown the filter element, it may blow the filter element over, affecting the dust removal efficiency. At the same time, in existing dust removal devices, the rollers push the slide plate to move, but in the actual dust removal process, the rollers are prone to self-slipping, and the dust collection cylinder may be displaced. The stability needs to be further improved. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a palladium-carbon catalyst filter element dust removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The palladium-on-carbon catalyst filter cartridge dust removal device includes:

[0010] A sliding plate is slidably connected to a base plate, and a dust collection cylinder is fixedly connected to the sliding plate. The air jet box is located directly above the dust collection cylinder.

[0011] A limiting seat is fixedly connected inside the dust collector cylinder. The limiting seat has an installation groove, and multiple sets of extrusion rubber rings are fixedly connected to the inner wall of the limiting seat.

[0012] Preferably, a first groove is provided on the base plate, and a first slider is slidably connected in the first groove, and the first slider is fixedly connected to the slide plate.

[0013] Furthermore, an adsorption block is fixedly connected in the first groove, a first magnet is fixedly connected to the adsorption block, and a second magnet is fixedly connected to the first slider, and the first magnet and the second magnet attract each other.

[0014] Preferably, an air supply ring is rotatably connected to the drive rod, an air supply pipe is fixedly connected to the bottom of the air supply ring, an air chamber is opened inside the air jet box, a cover plate is rotatably connected to the air jet box, the air supply pipe and the cover plate are fixedly connected, and the air supply pipe is connected to the air chamber.

[0036] Reference Figures 1-5 When in use, the staff pulls out the slide plate 8 and then places the filter element to be cleaned into the dust collection cylinder 2;

[0037] When placing the filter element, insert the filter element into the limiting seat 11. When the filter element is inserted into the mounting groove 1102, the compression rubber ring 1101 will stick to the side wall of the filter element, thereby limiting and fixing the filter element.

[0038] During dust removal, the air supply pipe 401 fills the air supply ring 4 with air, and the input air is fed into the air jet box 5 through the air supply pipe 402. The air is then ejected through the air jet holes on the side wall of the air jet box 5, thereby blowing off the dust and impurities on the side wall of the filter element.

[0039] After the initial dust removal is completed, the staff can reverse the filter element and install it on the limiting seat 11. After installation, the air jet box 5 is used again for secondary dust removal to ensure that the entire filter element can be effectively dust removed.

[0040] It should be noted that the air supply pipe 401 is made of stainless steel and is connected to an external air pump.

[0041] The base plate 7 has a first sliding groove 701, and a first slider 801 is slidably connected in the first sliding groove 701. The first slider 801 is fixedly connected to the slide plate 8.

[0044] Reference Figure 5 , Figure 6 When the slide plate 8 is pushed, the first slider 801 will slide in the first groove 701. When the dust collector 2 is directly below the air jet box 5, the first slider 801 is in contact with the adsorption block 12. At this time, the second magnet 8011 on the first slider 801 will attract the first magnet 1201 on the adsorption block 12. Through the attraction between the first magnet 1201 and the second magnet 8011, the stability of the first slider 801 is ensured, and the dust collector 2 will not be displaced during the dust removal process.
