[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-3 , the utility model provides an embodiment: a screening device for the production of reagent additives, including a shell 1, a support plate 2 is fixedly connected to one side of the shell 1, a motor 3 is fixedly connected to the bottom of the support plate 2, a transmission gear 4 is fixedly connected to the output end of the motor 3, a fan-shaped gear 5 is fixedly connected to the top of the transmission gear 4, a limiting block 6 is fixedly connected to the top of the support plate 2, a limiting groove 7 is provided inside the limiting block 6, a rack 8 is provided on the top of the limiting block 6, and a limiting block 2 9 is fixedly connected to the bottom of the rack 8, a slide groove 11 is provided inside the shell 1, a screen 12 is fixedly connected to one side of the rack 8, a limiting assembly is provided on one side of the screen 12, a feeding pipe 10 is fixedly connected to the top of the shell 1, and the limiting assembly includes a slider 13, one side of the slider 13 is fixedly connected to the other side of the screen 12, the outer wall of the slider 13 is slidably connected to the inside of the slide groove 11, the outer wall of the limiting block 29 is slidably connected to the inside of the limiting groove 7, and the rack 8 is meshed with the outer wall of the fan gear 5;

[0031] Specifically, first, the required raw materials are fed into the equipment housing 1 through the feeding pipe 10. The housing 1 is equipped with a fine screen 12 to ensure the accuracy of the screening process. Then, the motor 3 is started, and its output end drives the transmission gear 4 to start rotating. There are two groups of transmission gears 4 and sector gears 5, which are meshed with each other to transmit power and control direction. In particular, the rotation directions of the two groups of transmission gears 4 are opposite, which means that when the transmission gear 4 drives the sector gear 5 to rotate, the sector gear 5 on the other side will also be driven, so that the rack 8 The rack 8 moves back and forth in the limit groove 7 of the limit block 1 6. This reciprocating movement process is actually a precise control of the rack 8. Because the limit block 2 9 is arranged on the limit block 1 6, the movement range of the rack 8 is strictly limited to a certain interval. In this way, no matter what size the raw materials are, they can be effectively screened under the drive of the rack 8. The tiny holes inside the screen 12 play a screening role. No matter the size of the particles, they can reach the other side of the screen 12 only by passing through the tiny holes of the screen 12. In this way, the screening process becomes efficient and accurate.

[0032] Reference Figure 4 A box body 14 is fixedly connected to one side of the shell 1, a box door 17 is provided on one side of the box body 14, a pipe 16 is fixedly connected to the top of the box body 14, one end of the pipe 16 is fixedly connected to the inside of the shell 1, a card slot 18 and a card slot 21 are provided inside the box body 14, a fan 15 is fixedly connected to the inside of the box body 14, a frame 19 is provided inside the box body 14, a filter bag 20 is fixedly connected to the inside of the frame 19, and the outer wall of the frame 19 is slidably connected to the inside of the card slot 18, a frame 22 is provided inside the box body 14, a filter screen 23 is fixedly connected to the inside of the frame 22, and the outer wall of the frame 22 is slidably connected to the inside of the card slot 21;

[0033] Specifically, when the screen 12 is performing screening operations, the raised dust is inside the shell 1, and then the fan 15 will transport the dust to the box 14 through the pipe 16. Inside the box 14, the dust will be collected by the filter bag 20 to ensure clean air. After being filtered by the filter 23, the clean air is discharged from the box 14, thereby preventing secondary pollution. In order to facilitate cleaning and maintenance, the designer specially sets a box door 17. The operator can open the box door 17 to pull out the filter bag 20 for cleaning. At the same time, the filter 23 can also be pulled out and replaced through the frame 22. This design makes the cleaning and maintenance of the equipment very convenient and extends the service life of the equipment. It is worth mentioning that the filter 23 is made of polypropylene material, which has excellent wear resistance and tensile strength, can effectively block dust and ensure the filtering effect. During use, even if it runs for a long time, the filter 23 can maintain a high filtering efficiency, reducing the impact of dust on the production environment.

[0034] Working principle: When using the screening device for reagent and auxiliary production, firstly, the reagent and auxiliary is put into the screen 12 inside the shell 1 through the feeding tube 10, and then the output end of the motor 3 drives the transmission gear 4 to rotate, and the transmission gear 4 drives the rack 8 to move to the right through the fan gear 5. Since there are two groups of transmission gears 4 and fan gears 5, the two groups of transmission gears 4 are meshed, and the fan gears 5 are set in opposite directions, when the transmission gear 4 drives the fan gear 5 to rotate, the fan gear 5 on the other side drives the rack 8 to move to the left, and then the rack 8 is reciprocated, and the rack 8 is limited by the limit block 2 9 on the limit block 1 6. The groove 7 is limited inside, and when the rack 8 moves, it drives the screen 12 to move back and forth and then screens the raw materials inside the screen 12. The dust raised when the screen 12 is screened is sucked into the box body 14 through the pipe 16 by the fan 15, and is collected by the filter bag 20 inside the box body 14, and the clean air is discharged from the box body 14 after being filtered by the filter 23 to prevent secondary pollution. By opening the box door 17, the filter bag 20 can be pulled out through the frame 19 for cleaning, and the filter 23 can also be pulled out and replaced through the frame 22. The filter 23 is made of polypropylene and can block dust on it.
