Description

Technical Field

[0001] This utility model relates to the field of catalyst processing technology, specifically to a grinding and sieving device for catalyst processing. Background Technology

[0002] A catalyst is generally a substance that increases the reaction rate without changing the overall standard Gibbs free energy change. During the processing of catalysts, grinding is necessary to ensure that the particle diameter meets specifications.

[0003] Currently, catalysts require separate processing during grinding and sieving. For example, patents CN218132089U (authorization announcement number) and CN214766775U (authorization announcement number) disclose a grinding device for catalyst processing. In their use, two different devices are used for grinding and sieving the catalyst, resulting in low processing efficiency. Therefore, it is necessary to improve the grinding and sieving device for catalyst processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a grinding and sieving device for catalyst processing to solve the problems mentioned in the background art.

Limiting blocks are fixedly installed on the front and inside of the screening plate. An installation plate is fixedly installed on the left inner wall of the housing. A second motor is fixedly installed on the top of the installation plate. A cam is fixedly installed on the output end of the second motor. A fixing spring is fixedly installed between the left side of the screening plate and the left inner wall of the housing to facilitate the screening of the ground catalyst.

[0010] Preferably, the front and back inner walls of the box are provided with limiting grooves, and the limiting block is slidably installed inside the limiting groove, so as to allow the screening plate to slide within the box.

[0011] Preferably, the screening plate is inclinedly disposed inside the box, and the cam is in contact with the left side wall of the screening plate, so that the cam can drive the screening plate to slide.

[0012] Preferably, the sorting and collecting mechanism includes a first collecting box and a second collecting box.

[0014] Compared with the prior art, the present invention provides a grinding and sieving device for catalyst processing, which has the following beneficial effects:

[0015] This catalyst processing grinding and screening device, through its set grinding and screening mechanism, grinds the catalyst using a set grinding component during use. After grinding, the material falls onto a screening plate and is then screened, allowing two different materials to be stored separately. This achieves the effect of integrated grinding and screening of the catalyst, resulting in higher processing efficiency.

[0027] The grinding and screening mechanism 3 includes a grinding component 31 and a screening component 32. The grinding component 31 is disposed inside the housing 1 and extends to the top, while the screening component 32 is disposed inside the housing 1.

[0028] The grinding assembly 31 includes a grinding cylinder 311, which is fixedly installed inside the housing 1. A first motor 312 is fixedly installed on the top of the grinding cylinder 311, and a grinding roller 313 is fixedly installed on the output end of the first motor 312. A feed hopper 314 is fixedly installed on the top of the grinding cylinder 311 to facilitate the grinding of the catalyst.

[0029] Furthermore, the grinding roller 313 is rotatably installed inside the grinding cylinder 311, and the outer wall of the grinding roller 313 is provided with grinding texture, so as to facilitate the grinding of the catalyst by the grinding roller 313 and the grinding cylinder 311.

[0030] Furthermore, the screening assembly 32 includes a screening plate 321, which is slidably installed inside the housing 1. Limiting blocks 322 are fixedly installed on the front and inside of the screening plate 321. An installation plate 323 is fixedly installed on the left inner wall of the housing 1. A second motor 324 is fixedly installed on the top of the installation plate 323. A cam 325 is fixedly installed at the output end of the second motor 324. A fixing spring 326 is fixedly installed between the left side of the screening plate 321 and the left inner wall of the housing 1 to facilitate the screening of the ground catalyst.

[0031] Furthermore, limit grooves are provided on the front and back inner walls of the box 1, and the limit block 322 is slidably installed inside the limit groove, so that the screening plate 321 can be limited and slid inside the box 1.

[0032] Furthermore, the screening plate 321 is inclinedly disposed inside the housing 1, and the cam 325 contacts the left side wall of the screening plate 321, so that the cam 325 can drive the screening plate 321 to slide. Example

[0033] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the classification and collection mechanism 4 includes a first collection box 41 and a second collection box 42. Both the first collection box 41 and the second collection box 42 are slidably installed inside the housing 1 and extend to the front of the housing 1. Handles 43 are fixedly installed on the front of both the first collection box 41 and the second collection box 42. Two connecting frames 44 are fixedly installed on the front of both the first collection box 41 and the second collection box 42. Two fixing sleeves 45 are fixedly installed on the front of the housing 1. A sliding rod 46 is slidably installed inside the fixing sleeve 45. A connecting plate 47 is rotatably installed at the bottom of the sliding rod 46. An insertion block 48 is fixedly installed at the bottom of the connecting plate 47. A handle 49 is fixedly installed on the outside of the sliding rod 46, which facilitates the classification and collection of the screened materials.

[0034] Furthermore, two plug-in blocks 48 are fixedly installed at the bottom of the connecting plate 47, and the two plug-in blocks 48 are inserted into the inside of the connecting frame 44, so as to fix the first collection box 41 and the second collection box 42 through the plug-in blocks 48.

[0035] In actual operation, when this device is used, the catalyst material is fed into the grinding cylinder 311 through the feed hopper 314. The first motor 312 drives the grinding roller 313 to rotate inside the grinding cylinder 311, so that the catalyst material is ground and crushed between the grinding roller 313 and the grinding cylinder 311, and falls from the bottom of the grinding cylinder 311 onto the screening plate 321. The second motor 324 drives the cam 325 to rotate, and at the same time, with the help of the fixed spring 326, the cam 325 drives the screening plate 321 to reciprocate inside the box 1. The grinding catalyst material is screened through the screening plate 321, so that the material that passes through the screening plate 321 falls into the first collection box 41, and the material that cannot pass through the screening plate 321 falls into the second collection box 42.

[0036] The handle 49 drives the sliding rod 46 to slide upward, causing the sliding rod 46 to move the connecting plate 47 upward, causing the connecting plate 47 to separate the plug block 48 from the connecting frame 44. Then, the handle 49 is rotated, causing the handle 49 to rotate the sliding rod 46 on the connecting plate 47, so that the handle 49 rests on the top of the fixing sleeve 45. Then, the first collection box 41 and the second collection box 42 are pulled out from the box 1 by the handle 43.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
