Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to an automatic catalyst screening machine. Background Technology

[0002] Catalysts are an essential component in chemical production, playing a role in increasing reaction rates, reducing reaction costs, and pushing the reaction equilibrium point toward the products. The mass of a catalyst does not change before and after the reaction, and it can be reused after being separated from the reactants, which can reduce production costs. Therefore, the sieving process of catalysts is crucial.

[0003] For catalysts with particulate reactants, vibrating screens are often used for sieving. However, since the volume of reactants changes frequently during the reaction, the reactant particles often clog the screen holes, hindering the sieving process. This requires manual unclogging, which is time-consuming, labor-intensive, and affects work efficiency.

[0004] An investigation revealed that a Chinese utility model patent (publication number CN210146426U) discloses a catalyst screening device, comprising a working box. A conveying barrel and a servo motor are fixedly connected to the upper side of the working box via screws. The output shaft of the servo motor is fixedly connected to an auger via a coupling. The auger is placed inside the conveying barrel and fits against the inner wall of the conveying barrel. A feed hole is opened on the upper side of the conveying barrel near the servo motor, and a feed funnel is fixedly connected to the feed hole. A discharge hole is opened on the lower side of the other side of the conveying barrel, and a discharge pipe is fixedly connected to the discharge hole. Slide grooves are opened on both the front and rear side walls of the working box, and sliders are slidably connected within each slide groove. Springs are fixedly connected between the upper and lower ends of each slider and the slide groove. A vibrating screen is fixedly connected between two sliders. A baffle is fixedly connected to the end of the vibrating screen away from the servo motor via screws, and a vibrating motor is fixedly connected to the lower end of the vibrating screen via screws.

[0005] In the existing technology, small particulate impurities are removed and catalysts are separated by vibrating sieves. However, small particulate impurities are prone to clogging the sieve holes during the sieving process, making it impossible for the sieve holes to remove small particulate impurities and causing abnormal sieving operation. Therefore, a device that can clean the sieve holes during the sieving process is needed.

[0006] Therefore, this invention provides an automatic catalyst screening machine to solve the above problems. Utility Model Content

[0017] 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.

[0018] This utility model provides an automatic catalyst screening machine, such as... Figure 1-7 As shown, the device includes a frame assembly 1, a vibrating screen assembly 2 fixedly connected to the frame assembly 1, a track assembly 3 fixedly connected to the vibrating screen assembly 2, and an air curtain assembly 4 slidably connected to the track assembly 3. The frame assembly 1 includes a support 11, a shock absorber 12 fixedly connected to the support 11, a collection bucket 13 fixedly connected to one side of the support 11, and a support 14 fixedly connected to the shock absorber 12.

[0019] The vibrating screen assembly 2 includes a housing 21 fixedly connected to the support 14, a screen 22 fixedly connected to the housing 21, a screening channel 23 fixedly connected to the housing 21, a machine head 24 fixedly connected to the screening channel 23, and a collection hopper 25 fixedly connected to the housing 21.

[0020] The track assembly 3 includes a slide rail 31 fixedly connected to the inner wall of the outer shell 21, bearings 32 fixedly connected to both ends of the slide rail 31, a slide rod 33 fixedly connected to the bearings 32, and a limiting ring 34 fixedly connected to the end of the slide rod 33.

[0021] The track assembly 3 includes a power channel 35 fixedly connected to the inner wall of the outer casing 21, a lead screw 36 rotatably connected to the power channel 35, and a motor 37 fixedly connected to the end of the lead screw 36.

[0022] The air curtain assembly 4 includes a screw block 41 rotatably connected to a lead screw 36, a slider 42 slidably connected to a slide rod 33, a guide block 43 fixedly connected to the slider 42, a telescopic air passage 44 fixedly connected to the guide block 43, a throat constriction passage 45 fixedly connected to the end of the telescopic air passage 44, and a duct 46 fixedly connected to the throat constriction passage 45.

[0023] The guide block 43 is provided with an air outlet groove 47, a flat groove 48 inside the guide block 43, and an air inlet groove 49 inside the guide block 43.

[0024] Specifically, the bracket 11 and shock absorber 12 in the frame assembly 1 are responsible for providing stable support, the collection bucket 13 collects the screened material, and the support 14 gives the vibrating screen assembly 2 dynamic balance capability. After the material is put into the vibrating screen assembly 2, the material is separated by the screen 22 and the screening channel 23. Part of the material falls into the collection bucket 13 at the machine head 24 position, and the other part falls from the collection hopper 25.

[0025] During the screening process, since the material or catalyst is particulate, it is easy to get stuck in the holes of the screen 22, clogging the screen 22 and causing screening failure. The bearing 32 and lead screw 36 in the slide 31 mainly play an auxiliary role, working with the motor 37 to drive the lead screw 36. The slide bar 33 is slidably connected to the slider 42, and the lead screw 36 is rotatably connected to the screw block 41. Under the rotation of the motor 37, the lead screw 36 rotates, and the screw block 41 moves forward or backward, driving the guide block 43 to move forward or backward in conjunction with the slider 42. After the duct 46 blows the high-pressure airflow into the telescopic air passage 44, the airflow enters the flat groove 48 through the air inlet groove 49 and is sprayed out from the air outlet groove 47, sweeping the screen 22.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
