Description

Technical Field

[0001] This utility model belongs to the field of cat litter production, specifically relating to a centrifugal impurity removal and screening machine for cat litter bentonite. Background Technology

[0002] The centrifugal impurity removal and screening machine for bentonite cat litter is a specialized piece of equipment used in the production of bentonite cat litter. It is mainly used to remove impurities from raw materials, such as stones, metal particles, and coarse sand, and to screen bentonite particles of different sizes to improve the purity and uniformity of cat litter. Its core principle is to achieve efficient separation through the combination of centrifugal force and screen.

[0003] Existing cat litter bentonite is mostly screened using centrifugal impurity removal screening machines. Ordinary centrifugal impurity removal screening machines typically have relatively simple feeding systems, mostly using gravity feeding conveying methods, which makes it difficult to control the uniformity of materials. In actual production, the amount of material fed may fluctuate, resulting in uneven material distribution on the screen surface. When the amount of material fed is too large, the material is prone to accumulate in local areas of the screen, increasing the load on the screen, reducing screening efficiency, and may even cause screen blockage. Uneven feeding will also cause inconsistent movement trajectories of materials on the screen, and some materials may be discharged without being fully screened, resulting in unstable screening quality. Utility Model Content

[0004] To overcome the problem that uneven feeding may occur when a large amount of material is fed into a bentonite screening machine, thus affecting the screening quality of bentonite, a centrifugal impurity removal screening machine for cat litter bentonite is proposed.

[0005] The technical solution of this utility model is as follows: a centrifugal impurity removal screening machine for cat litter bentonite, comprising a screening machine body and a feeding cylinder. A support frame is fixedly connected to the upper inner wall of the feeding cylinder, and a bearing is fixedly connected to the center inner wall of the support frame. A rotating shaft is provided on the inner wall of the inner ring of the bearing. The outer wall of the rotating shaft fits against the inner wall of the inner ring of the bearing. A rotating disk is fixedly connected to the lower end of the rotating shaft. Four first sliders equidistantly surrounding the rotating disk are fixedly connected to the outer wall of the rotating disk. A first sliding groove is opened on the inner wall of the feeding cylinder, which surrounds the feeding cylinder. The first sliders are adapted to the first sliding groove. A discharge port is opened through the upper end of the rotating disk. A servo motor is installed on the upper end of the support frame. The output end of the servo motor is connected to the upper end of the rotating shaft. The feeding cylinder is installed on the upper end of the screening machine body through a flange. A cylinder cover is hinged to the upper end of the feeding cylinder.

[0006] Furthermore, a baffle is provided at the upper end of the rotating disk, and a limiting hole is opened through the upper edge of the baffle. The inner wall of the limiting hole is fitted with the outer wall of the rotating shaft, and the lower end of the baffle is attached to the upper end of the rotating disk.

[0007] Furthermore, the baffle is larger than the material inlet, and four second sliders are fixedly connected at equal intervals around the lower edge of the rotating disk, and a limit ring is fixedly connected to the lower inner wall of the feeding cylinder.

[0008] Furthermore, a second sliding groove is provided at the upper end of the limiting ring, which surrounds the limiting ring, and the second slider is adapted to the second sliding groove.

[0009] Furthermore, six shock absorbers are provided at the lower end of the screening machine body, equidistantly surrounding the screening machine body, and the output ends of the shock absorbers are all fixed to the lower end of the screening machine body.

[0010] Furthermore, the fixed ends of the shock absorbers are all fixedly connected to the base, and a dust collector is installed on one side of the discharge port of the main body of the screening machine.

[0011] Furthermore, the feed pipe of the vacuum cleaner is connected to the discharge port of the main body of the screening machine, and a collection box is fixedly connected to the opening of the discharge pipe of the vacuum cleaner.

[0012] The beneficial effects of this utility model are as follows: The rotating disk can be supported by the first slider and the first groove, and the bearing installed on the support frame can support the rotating shaft, thereby ensuring the stability of the rotating disk. The output end of the servo motor can drive the rotating shaft to rotate, so that the rotating disk and the material discharge port that is opened through it can rotate along the inner wall of the feeding cylinder, thereby evenly spreading the bentonite in the feeding cylinder into the screen body, so that the bentonite is circumferentially spread on the screen in the screen body. Compared with the existing bentonite impurity removal screening machine, the added rotating disk structure can be driven by the servo motor to rotate the rotating disk, so that the material discharge port rotates along the inner wall of the feeding cylinder, and the bentonite is circumferentially spread on the screen in the screen body, improving the uniformity of feeding and reducing the phenomenon of screen blockage and incomplete screening caused by uneven feeding.

[0021] The first slider 14, in conjunction with the first groove 16, can support the rotating disk 6. The bearing 12 installed on the support frame 11 can support the rotating shaft 7, thereby ensuring the stability of the rotating disk 6. The output end of the servo motor 13 can drive the rotating shaft 7 to rotate, so that the rotating disk 6 and the material discharge port 8 through it can rotate along the inner wall of the feeding cylinder 2, thereby evenly sprinkling the bentonite in the feeding cylinder 2 into the screening machine body 1, so that the bentonite is circumferentially spread on the screen inside the screening machine body 1, which can improve the screening quality of bentonite and reduce screen blockage and incomplete screening.

[0022] Please see Figures 3-4In this embodiment, a baffle 9 is provided at the upper end of the rotating disk 6. A limiting hole 10 is provided through the upper edge of the baffle 9. The inner wall of the limiting hole 10 is fitted with the outer wall of the rotating shaft 7. The lower end of the baffle 9 is attached to the upper end of the rotating disk 6. In use, the material discharge port 8 can be blocked by rotating the baffle 9, thereby adjusting the size of the material discharge port 8 and controlling the material discharge speed. The baffle 9 is larger than the material discharge port 8. Four second sliders 15 are fixedly connected to the lower edge of the rotating disk 6 at equal intervals around the rotating disk 6. A limiting ring 17 is fixedly connected to the lower inner wall of the feeding cylinder 2. In use, the limiting ring 17 can support the rotating disk 6 and improve the stability of the rotating disk 6 during operation.

[0023] Please see Figures 4-5 In this embodiment, the upper end of the limiting ring 17 is provided with a second sliding groove 18 that surrounds the limiting ring 17. The second slider 15 is adapted to the second sliding groove 18. In use, the second slider 15 slides against the second sliding groove 18, which can further improve the stability of the rotating disk 6. The lower end of the screening machine body 1 is provided with six shock absorbers 19 that are equidistantly arranged around the screening machine body 1. The output ends of the shock absorbers 19 are fixed to the lower end of the screening machine body 1. In use, the shock absorbers 19 can reduce the vibration of the screening machine body 1 and reduce the impact of the screening machine body 1 on the environment.

[0024] Please see Figure 5 In this embodiment, the fixed end of the shock absorber 19 is fixedly connected to the base 5. A vacuum cleaner 20 is provided on one side of the discharge port of the screening machine body 1. During use, the base 5 can support the screening machine body 1 and improve the stability of the screening machine body 1. The vacuum cleaner 20 can adsorb the screened bentonite.

[0025] During operation, first, start the main body 1 of the screening machine and open the cylinder cover 3. According to the needs of bentonite, rotate the baffle 9 to adjust the size of the discharge port 8. Then, place a container under the waste port of the main body 1 of the screening machine. Next, start the servo motor 13. The output end of the servo motor 13 drives the rotating shaft 7 to rotate. After the servo motor 13 drives the rotating disk 6 to rotate, pour the bentonite to be screened into the feeding cylinder 2. Then, close the cylinder cover 3 and wait for the main body 1 of the screening machine to screen the bentonite. Finally, after the screening is completed, start the vacuum cleaner 20 and wait for the vacuum cleaner 20 to collect the screened bentonite and discharge it into the collection box 4. Turn off the servo motor 13, the main body 1 of the screening machine and the vacuum cleaner 20, and take out the screened bentonite.

[0026] Through the above steps, the first slider 14, in conjunction with the first slide groove 16, can support the rotating disk 6, the bearing 12 installed on the support frame 11 can support the rotating shaft 7, and the output end of the servo motor 13 can drive the rotating shaft 7 to rotate, so that the rotating disk 6 and the material discharge port 8 through it can rotate along the inner wall of the feeding cylinder 2, thereby evenly sprinkling the bentonite in the feeding cylinder 2 into the screen body 1, so that the bentonite is circumferentially spread on the screen inside the screen body 1, which solves the problem that a large amount of material feeding may cause uneven feeding when the bentonite screening machine is in use, thus affecting the bentonite screening quality.
