Description

Technical Field

[0001] The utility model relates to the technical field of desiccant production and processing, and more specifically, particularly relates to a screening device for desiccant production. Background Art

[0002] Desiccant refers to a substance that can remove moisture from moist substances. It is usually divided into two categories: chemical desiccant and physical desiccant. For example, calcium sulfate and calcium chloride can dry by combining with water to form hydrates. Silica gel and activated alumina can dry by physically adsorbing water. In the production process, silica gel desiccant of different particle sizes needs to be screened to select a variety of desiccants of different particle sizes for subsequent processing of the desiccant.

[0003] However, there are various types of screening devices in the prior art. For example, utility model patent CN214766839U relates to a screening device for desiccant production. The utility model drives a disc to rotate through a motor so that the first end of the first connecting rod makes a circular motion on the disc, and the second end of the first connecting rod is hinged to the second connecting rod. Since the second connecting rod passes through the shell, when the first connecting rod moves, the second connecting rod will be limited and move left and right to drive the screen to move left and right. The elastic part on one side can make the screen move back and forth continuously, thereby efficiently screening the desiccant and solving the problem of low screening efficiency.

[0004] Although the screening device can effectively screen the desiccant, a fixed screen is installed in the device. If the screen mesh number is not suitable, the fixed screen is difficult to replace, and without replacing the screen, the desiccant cannot be screened into multiple parts with different particle sizes at one time, which is not convenient for obtaining desiccant with multiple different particle sizes. In order to avoid this phenomenon, it is very necessary to design a screening device for desiccant production. Utility Model Content

The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, it is a schematic diagram of the structure of the screening device for desiccant production in this embodiment. The screening device for desiccant production in this embodiment is used to screen desiccants of different particle sizes in the production process, and screen out a variety of desiccants of different particle sizes to facilitate subsequent processing of the desiccant. The screening device includes a screening box 1 and a screening basket 3. Two movable frames 2 are reciprocatingly slidably installed inside the screening box 1. The two movable frames 2 are embedded with screening baskets 3 inside. The inner bottom walls of the screening baskets 3 are provided with assembly grooves 4. The assembly grooves 4 are used to place the matching fixed frames 5 inside. The assembly grooves 4 are embedded with fixed frames 5 inside. The inner walls of the two fixed frames 5 are respectively fixedly connected with a primary screen 6 and a secondary screen 7. The secondary screen 7 is located below the primary screen 6, and two grooves are provided inside the screening basket 3. The front of the screening box 1 is provided with a retrieval box door 26 through a hinge. After the desiccant is put into the screening box 1, the desiccant will enter the upper screening basket 3, and the primary screen 6 will be used to preliminarily screen the desiccant to screen out the large-particle desiccant, and the remaining desiccant will enter another screening basket 3. The aperture of the secondary screen 7 is smaller than that of the primary screen 6, and the secondary screen 7 is used to further screen the desiccant to screen out the larger desiccant. On the basis of not changing the screen, the desiccant can be screened into multiple parts with different particle sizes at one time, and not only desiccant with large and small particles can be obtained, so as to facilitate the subsequent use of multiple desiccant.

[0028] In addition, if Figure 4As shown, in this embodiment, moving blocks 8 are slidably installed inside the grooves, and the two moving blocks 8 are symmetrically arranged.

The screening basket 3 is removed from the movable frame 2, the screening basket 3 is turned over and turned upside down, and the two adjusting rods 12 are moved with the back of the hand to drive the two moving blocks 8 to move, so that the plug-in block 10 withdraws from the slot 11, and the fixing effect on the fixed frame 5 is released, so that the fixed frame 5 falls directly, so that the screen can be removed for replacement, so that the screen with a suitable mesh number can be replaced according to actual needs, which is convenient for screening the desiccant.

[0029] like Figure 6 As shown, in this embodiment, the inner wall of the movable frame 2 is provided with two matching ridges 13, and matching grooves are provided on both side surfaces of the screening basket 3.
