Technical Field

[0001] The utility model relates to the technical field of platinum catalyst production, in particular to a filtering device for platinum catalyst production. Background Technique

[0002] Platinum catalyst is a catalyst with noble metal platinum (Pt) element as the main active ingredient, which usually plays a catalytic role in chemical reactions. In the production process of platinum catalyst, filtration is a common step, which can be used to remove impurities and impure substances to improve the purity and performance of platinum catalyst.

[0003] At present, most of the filtering devices used in platinum catalyst production adopt filter screens for filtration. As the use time increases, the impurities on the filter screens gradually increase, so they need to be replaced regularly. During the replacement process, since the outer shell needs to be opened and taken out, the filtering device cannot be used continuously at this time, which affects normal filtration and also causes the subsequent processes to be unable to continue. Content of the Utility Model

[0004] The utility model provides a filtering device for platinum catalyst production, which has the advantage that the filter screen can be replaced during operation, so as to solve the problems put forward in the background technique.

At the mutually remote ends of the upper and lower first tubes, second brackets are integrally connected respectively. A plurality of telescopic rods are fixedly connected between the first bracket and the second bracket. At the mutually remote ends of the upper and lower toothed rods, they are respectively fixedly connected to the two first brackets.

[0009] As a preferred technical solution of the present utility model, the moving mechanism includes a slide rail. The upper and lower inner walls of the slide rail are rotatably connected with a screw rod. The screw rod is threadedly connected with three sliders that are slidably connected to the upper and lower parts of the slide rail. A long opening is formed on the front surface of the slide rail. A long strip is screwed and installed on the front surface of the middle slider. Two threaded rods are threadedly connected to the front surface of the long strip.

When the first tube and the second tube are in the lower position, the sealing piece fits on the other sealing block. At this time, the platinum catalyst raw material to be filtered can pass through one of the first tubes. When replacing the filter mesh, the filtering device can still continue to be used, without delaying the production of the entire platinum catalyst.

[0013] 2. For the filtering device for the production of platinum catalysts, only by driving the screw rod to rotate can the switching be realized, and the operation is convenient.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention discloses a filtering device for the production of platinum catalysts, including a moving mechanism 10. Two connectors 20 are provided at the rear end of the moving mechanism 10. One end of the upper and lower connectors 20 close to each other is integrally connected with a metal bellows 30. One end of the upper and lower metal bellows 30 close to each other is integrally connected with a first pipe body 40. A pair of second pipe bodies 50 are clamped between the upper and lower first pipe bodies 40. A pair of filter mesh sheets 60 are clamped in each of the two second pipe bodies 50. Insertion cylinders 70 are inlaid on the front surfaces of the two second pipe bodies 50. A sealing block 80 integrally connected with its inner wall is provided in the first pipe body 40. Openings 90 are formed on the inclined surfaces above the two sealing blocks 80. An opening and closing mechanism 100 is provided in the first pipe body 40.

[0022] In this implementation scheme, the connector 20 is provided with a connecting flange to achieve flange connection. The filter mesh sheet 60 can filter the platinum catalyst raw materials. The filter holes of the filter mesh sheet 60 at the upper position are larger than those of the filter mesh sheet 60 at the lower position.

[0023] Specifically, the opening and closing mechanism 100 includes a gear 110. A rack 120 is meshed with the side end of the gear 110. A sealing sheet 130 is integrally connected to the rear end of the gear 110. The sealing sheet 130 is in close fit with one of the sealing blocks 80. The meshing connection directions of the upper and lower racks 120 with the gear 110 are opposite. The front and rear ends of the gear 110 are respectively axially connected to the front and rear inner walls of the first pipe body 40.

[0024] In this embodiment, it can be used in cooperation with the moving mechanism 10 and can drive the sealing piece 130 to swing, so as to switch the outflow direction of the platinum catalyst raw material, so that the filter mesh 60 can be replaced without stopping the filtration of the platinum catalyst raw material.

[0025] Specifically, a first bracket 200 integrally connected to the inner wall thereof is provided inside the joint 20. Second brackets 210 are integrally connected to the mutually remote ends of the upper and lower first pipe bodies 40. A plurality of telescopic rods 220 are fixedly connected between the first bracket 200 and the second bracket 210. The mutually remote ends of the upper and lower racks 120 are fixedly connected to the two first brackets 200 respectively.

[0026] In this embodiment, the combination of the first bracket 200, the second bracket 210 and the telescopic rods 220 can improve the stability of the expansion and contraction of the metal bellows 30, and at the same time facilitate the connection of the rack 120 to prevent the rack 120 from being in a suspended state.

[0027] Specifically, the moving mechanism 10 includes a slide rail 11. A screw rod 12 is rotatably connected to the upper and lower inner walls of the slide rail 11. The screw rod 12 is threadedly connected to three sliders 13 that are slidably connected to the upper and lower parts of the slide rail 11. A long opening 14 is formed in the front surface of the slide rail 11. A long bar 15 is screw-mounted on the front surface of the middle slider 13. Two threaded rods 16 are threadedly connected to the front surface of the long bar 15. The two threaded rods 16 are respectively inserted into two insertion cylinders 70. The front surfaces of the two joints 20 are welded to the back surface of the slide rail 11. The back surfaces of the upper and lower sliders 13 are respectively welded to the front surfaces of the two first pipe bodies 40.

[0028] In this embodiment, a turning handle integrally connected to the bottom of the screw rod 12 is provided directly below the slide rail 11, which is convenient for driving the screw rod 12 to rotate. The threaded rod 16 is inserted into the insertion cylinder 70, which can lock the second pipe body 50 after clamping, and improve the tightness between the second pipe body 50 and the first pipe body 40.

[0029] The working principle and usage process of the present utility model: Rotating the turning handle forward drives the screw rod 12 to rotate forward. At this time, the first pipe body 40 and the second pipe body 50 move upward together, so that the position of the gear 110 gradually moves upward. Since the position of the rack 120 remains unchanged, the gear 110 will rotate at this time and drive the sealing piece 130 to swing. The sealing piece 130 fits onto another sealing block 80, and the opening 90 can be sealed. Then, reverse the threaded rod 16 to separate it from the insertion cylinder 70. The second pipe body 50 to be removed loses its lock and can be directly removed. Then, the clamped filter mesh 60 is removed. After cleaning, it is re-clamped. The second pipe body 50 and the first pipe body 40 are clamped and connected. Rotate the threaded rod 16 forward so that its rear end is inserted into the insertion cylinder 70, and the locking of the second pipe body 50 after clamping can be achieved.
