Specific embodiments

[0021] 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.

[0022] Please refer to Figures 1 - 3 , a centrifuge for barium carbonate production in this embodiment includes a base 1, a first motor 4 is fixed at the lower end of the base 1, an outer shell 2 is provided on the base 1, the outer shell 2 is fixedly installed on the base 1, a liquid discharge port 6 is fixed on one side of the outer shell 2, the output end of the first motor 4 is fixed with a filter cylinder 3, the filter cylinder 3 is rotatably connected to the bottom of the outer shell 2, and a cleaning mechanism 8 is provided in the filter cylinder 3.

[0023] The cleaning mechanism 8 includes a fixing plate 803, an air supply assembly 5 and a drive assembly 7. A plurality of fixing plates 803 are vertically arranged in the filter cylinder 3. A cavity 801 is opened in the fixing plate 803. A first piston plate 804 is closely slid in the cavity 801. A plurality of telescopic rods 805 are fixed on one side of the first piston plate 804. Springs 806 are sleeved on the telescopic rods 805. By providing a plurality of springs 806, when the first piston plate 804 and the second piston plate 811 perform piston movement, the subsequent elastic force of the plurality of springs 806 enables the first piston plate 804 and the second piston plate 811 to return to the initial position faster. The two ends of the spring 806 are respectively fixed to the inner side wall of the cavity 801 and the fixing plate 803.

[0024] In the middle of one side of the fixed plate 803, a scraper 802 is fixed. A through groove 807 communicating with the cavity 801 is formed in the fixed plate 803. Two piston rods 808 are fixed on one side of the piston plate. One end of the piston rod 808 is fixed with a cleaning block 809. One side of the cleaning block 809 is slidably connected with the scraper 802. A second piston plate 811 slidably matched with the through groove 807 is fixed on the piston rod 808 to prevent solid-liquid from entering the through groove 807 from the gap.

[0025] An air supply groove 812 communicating with the cavity 801 is formed in the fixed plate 803. An air supply assembly 5 for supplying air into the cavity 801 is arranged on the air supply groove 812. A driving assembly 7 for driving the fixed plate 803 to rotate is arranged on the fixed plate 803.

[0026] The device supplies air into the air supply groove 812 through the air supply assembly 5. Then the gas enters the cavity 801. The first piston plate 804 pushes the piston rod 808 to move. The first piston plate 804 compresses the spring 806. The spring 806 retracts. Then the cleaning block 809 is driven to move through the piston rod 808. The cleaning block 809 moves in contact with both sides of the scraper 802, so as to push down and clean the materials on both sides of the scraper.

[0027] Wherein, a sealing gasket 810 is fixed on one side of the fixed plate 803 to prevent solid-liquid from entering the through groove 807 from the gap. The piston rod 808 penetrates through the sealing gasket 810 and is slidably connected with it. The two cleaning blocks 809 are located on both sides of the scraper 802, and their cross sections are trapezoidal.

[0028] At the same time, the driving assembly 7 includes a second motor 701 and a rotating shaft 704. A rotatable rotating shaft 704 is vertically arranged in the housing 2. The second motor 701 is fixed on the housing 2. The output end of the second motor 701 is fixed with a driving bevel gear 702. A driven bevel gear 703 meshing with the driving bevel gear 702 is fixed on the rotating shaft 704. A plurality of connecting pipes 705 are fixed on the outer side of the rotating shaft 704. One side of the connecting pipe 705 is fixed with the other end of the fixed plate 803. By starting the second motor 701, the second motor 701 drives the driving bevel gear 702 to rotate. Then the driving bevel gear 702 meshes with the driven bevel gear 703, so that the rotating shaft 704 can rotate. Then the connecting pipe 705, the fixed plate 803 and the scraper are driven by the rotating shaft 704 to rotate to scrape the materials on the inner wall of the filter cylinder 3.

[0029] Please refer to Figure 1, in this embodiment, the air supply assembly 5 includes an air pump 501, an air collection box 502 and a rotary joint 505. The air pump 501 and the air collection box are fixedly installed on the housing 2 in sequence. The output end of the air pump 501 is communicated with the air collection box 502. A drain pipe 503 is fixed to the upper end of the air collection box 502. The other side of the air collection box 502 is communicated with an air delivery pipe 504. A rotary joint 505 is rotatably installed on the rotating shaft 704. One end of the air delivery pipe 504 is communicated with the rotary joint 505. The rotating shaft 704 and the rotary joint 505 are connected through a sealing bearing. The inner ring of the sealing bearing is fixedly connected to the outer wall of the rotating shaft 704, and the outer ring of the sealing bearing is in interference fit with the inner wall of the rotary joint 505 to prevent gas leakage.

[0030] The device works by starting the air pump 501. The air pump 501 delivers gas into the air collection box 502, then through the air collection box 502 to the air delivery pipe 504 and the rotary joint 505, and then the gas is delivered to the rotating shaft 704 and the connecting pipe 705, so that the gas enters the air supply groove 812 and the cavity 801, and then pushes the first piston plate 804 to move.

[0031] Among them, a solenoid valve is fixed on the drain pipe 503 to control the outflow of gas.

[0032] The working principle of the above embodiment is as follows:

[0033] When it is necessary to clean the material on the inner wall of the filter cartridge 3, the air pump 501 and the second motor 701 can be used to start the air pump 501. The air pump 501 delivers gas into the air collection box 502, then through the air collection box 502 to the air delivery pipe 504 and the rotary joint 505, and then the gas is delivered to the rotating shaft 704 and the connecting pipe 705, so that the gas enters the air supply groove 812 and the cavity 801, and then pushes the first piston plate 804 to move. The first piston plate 804 compresses the spring 806, and the spring 806 retracts. Then, the cleaning block 809 is driven to move through the piston rod 808. The cleaning block 809 contacts both sides of the scraper 802 and moves towards the inner peripheral wall of the filter cartridge 3, so as to push down and clean the materials on both sides of the scraper.

[0034] At the same time, the second motor 701 drives the driving bevel gear 702 to rotate, and then the driving bevel gear 702 meshes with the driven bevel gear 703, so that the rotating shaft 704 can rotate. Then, the connecting pipe 705, the fixing plate 803 and the scraper are driven to rotate by the rotating shaft 704 to scrape the materials on the inner wall of the filter cartridge 3.

[0035] Then, by opening the solenoid valve, the gas in the cavity 801 is deflated. Subsequently, the first piston plate 804 is driven back to the initial position by the resilience of the spring 806. This process is repeated to scrape and clean both sides of the scraper 802.
