Description

Technical Field

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

[0002] Filtration is an essential and important step in chemical production. During the production process of chemical products, due to the reaction of two or more chemical materials together, precipitated substances, flocculent substances, reaction residues, etc. may be generated. Before the subsequent processing, the newly formed products after the reaction are generally filtered to separate the chemical liquid from the residues.

[0003] After a large amount of retrieval, it is found that the Chinese patent with the publication number CN212396037U in the prior art discloses a filter for chemical production. This patent adds the liquid to be filtered into the filter body through the liquid inlet pipe, filters through the filter screen, and discharges the filtered liquid through the liquid outlet. The filtered impurities will accumulate on the top of the filter screen. The motor drives the connecting rod to rotate the second scraper to scrape and concentrate the impurities on the top of the filter screen to prevent the filter screen from being blocked. This filter for chemical production effectively prevents impurities from blocking the filter screen, keeps the filtration flow rate of the filter screen, prevents affecting the work efficiency, and can clean the inner wall of the filter body and is convenient for replacing the filter screen. However, in this patent, since the position of the liquid inlet pipe is fixed, when the staff pours the chemical liquid into the liquid inlet pipe, the chemical liquid may only contact the area directly below the liquid inlet pipe on the filter screen, resulting in a small contact area between the chemical liquid and the filter screen, so that the overall utilization rate of the filter screen is low, affecting the staff's use of the filter screen to filter the chemical liquid. Therefore, based on the above retrieval and in combination with the prior art, the utility model proposes a filtering device for chemical production to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a filtering device for chemical production to solve the problems put forward in the above background technique.

Specific embodiments

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

[0021] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a filtering device for chemical production, including a processing box 1, a feed hole 2 is opened on the top surface of the processing box 1, a feed hopper 3 is fixedly sleeved inside the feed hole 2, a support frame 16 is slidably connected inside the processing box 1, a filter screen 17 is fixedly sleeved inside the support frame 16, a filtering component 4 for filtering chemical liquids is arranged on one side inside the processing box 1, and a reflux component 5 for filtering chemical liquids multiple times is arranged on one side of the processing box 1;

[0022] The filtering component 4 includes a support disk 23 which is rotatably connected to one side inside the processing box 1. A driving motor 10 for driving the support disk 23 to rotate is fixedly installed on one side of the processing box 1. A rotating hole 24 is formed on one side of the processing box 1. The outer circumferential wall surface of the driving shaft of the driving motor 10 is movably sleeved with the inner circumferential wall surface of the rotating hole 24. One end of the driving shaft of the driving motor 10 is fixedly connected to one side of the support disk 23. A connecting ring 25 is slidably connected to one side of the support disk 23. A support column 26 is fixedly installed on one side of the support disk 23. The support column 26 penetrates through the connecting ring 25 and slides inside the connecting ring 25. A circular groove is formed on one side inside the processing box 1. A bearing 22 is fixedly sleeved on the inner circumferential wall surface of the circular groove. The inner circumferential wall surface of the inner ring of the bearing 22 is fixedly sleeved with a connecting roller 9. One end of the connecting roller 9 is fixedly connected to one side of the connecting ring 25. The upper end of the connecting ring 25 is rotatably connected to the support frame 16. A connecting frame 27 is fixedly installed on the bottom surface of the support frame 16. A positioning column 28 is fixedly installed on one side of the connecting ring 25. The positioning column 28 penetrates through the connecting frame 27 and slides inside the connecting frame 27. Vibration motors 8 for vibrating the filter screen 17 are fixedly installed on both sides of the support frame 16. When using the filter screen 17 to filter chemical liquid, the staff starts the vibration motors 8. The vibration of the vibration motors 8 drives the support frame 16 and the filter screen 17 to vibrate, thereby preventing the residues in the chemical liquid from getting stuck in the filter screen 17. A PLC controller is fixedly installed on one side of the processing box 1. The vibration motors 8 and the driving motor 10 are both electrically connected to the PLC controller;

[0023] By providing the processing box 1, before the staff uses the filter screen 17 inside the processing box 1 to filter chemical liquid, the staff starts the driving motor 10. The driving shaft of the driving motor 10 rotates to drive the support disk 23 to rotate. The rotation of the support disk 23 drives the support column 26 to perform circular motion. The circular motion of the support column 26 causes the lower end of the connecting ring 25 to drive the inner ring of the connecting roller 9 and the bearing 22 to rotate. The bearing 22 and the connecting roller 9 cooperate to limit the rotation of the connecting ring 25. At this time, the connecting ring 25 swings left and right along the support disk 23 with the connecting roller 9 and the bearing 22 as endpoints. The left and right swinging of the upper end of the connecting ring 25 causes the positioning column 28 to drive the connecting frame 27 to move left and right and at the same time causes the positioning column 28 to slide inside the connecting frame 27. The left and right swinging of the connecting frame 27 drives the support frame 16 and the filter screen 17 to move left and right;

[0024] Then the staff pours the chemical liquid into the inside of the feed hopper 3. Since the filter screen 17 moves left and right inside the processing box 1, the area of the chemical liquid that can contact the filter screen 17 is enlarged, preventing the chemical liquid from only contacting a part of the filter screen 17 directly below the processing box 1, improving the overall utilization rate of the filter screen 17, helping the staff to better use the filter screen 17 to filter the residues in the chemical liquid, achieving the filtering effect of the chemical liquid, and facilitating the staff to handle the chemical liquid in chemical production;

[0025] On both inner sides of the processing box 1, limiting grooves 21 for the sliding of the support frame 16 are provided. On both sides of the support frame 16, limiting blocks 20 are fixedly installed. By providing the support frame 16, the left - right movement of the support frame 16 and the filter screen 17 enables the limiting blocks 20 to slide inside the limiting grooves 21 on the inner side of the processing box 1. The limiting blocks 20 and the limiting grooves 21 can limit the movement of the support frame 16 and the filter screen 17, achieving the limiting effect on the support frame 16 and the filter screen 17.

One end of the connecting pipe 13 is connected to the feed hopper 3. A circular through - hole is provided on one side of the feed hopper 3. The outer circumferential wall of the pump body 12 is fixedly sleeved with the inner circumferential wall of the circular through - hole. On one side of the processing box 1, an anti - swaying member for preventing the connecting pipe 13 from swaying is provided. The anti - swaying member includes a connecting column 15. The connecting column 15 is fixedly installed on one side of the processing box 1. On one side of the connecting column 15, a support ring 14 is fixedly installed. The inner circumferential wall of the support ring 14 is fixedly sleeved with the outer circumferential wall of the pump body 12. By providing the support ring 14 and the connecting column 15, the support ring 14 and the connecting column 15 can support the connecting pipe 13, avoiding the swaying of the connecting pipe 13 when conveying chemical liquid, achieving the anti - swaying effect on the connecting pipe 13;

[0027] By providing the processing box 1, the filtered chemical liquid inside the processing box 1 will gather on the inner bottom surface of the processing box 1. The staff starts the pump body 12, and the pump body 12 conveys the filtered chemical liquid inside the processing box 1 back into the feed hopper 3 through the connecting pipe 13, so that the filtered chemical liquid flows back into the processing box 1 for re - filtration, achieving the reflux effect on the chemical liquid;

[0028] A valve 19 is installed on the bottom surface of the processing box 1. An outlet hole 18 is provided on the bottom surface of the processing box 1.
