[0036] The device cover 2 can be adapted to the device body 1 to achieve sealing of the device body 1, ensuring that the device is a closed container. The pressure relief valve 3 can adjust the air pressure in the device body 1 so that the air pressure in the device body 1 can reach the optimal filtering air pressure to prevent the air pressure from being too high and affecting the filtering speed. The hollow horizontal plate 13 can make the filtered paint easily fall onto the guide plate 9, and the guide plate 9 can make the filtered paint flow out of the discharge port 10 faster.

[0037] Furthermore,

[0038] The pressurized anti-blocking mechanism 6 includes a connecting block 60, an air pipe 61, a nozzle 62, and a partition 63. The upper end of the connecting block 60 is connected to the threaded connecting pipe, and the lower end is connected to the air pipe 61. The nozzle 62 is installed on the inner side of the air pipe 61. The partition 63 is installed on one side of the air outlet of the nozzle 62 and can cover all the nozzles 62. The upper end of the partition 63 passes through the device cover 2, and the lower end is in active contact with the hollow horizontal plate 13.

[0039] One end of the connecting block 60 is connected to the threaded connecting pipe 5, and the other end is connected to the air pipe 61 to connect the air pipe 61 and the threaded connecting pipe 5. The partition 63 can be removed by taking the part outside the device body 1. The partition 63 blocks all the nozzles 62 to prevent paint from splashing onto the nozzles 62 when the filter assembly 7 rotates, causing the nozzles 62 to be blocked.

[0040] Furthermore,

[0041] The rotating mechanism 8 includes a protection box 80, a rotating rod 81, and a motor 82. The protection box 80 is placed in the middle of the hollow horizontal plate 13. The motor 82 is inside the protection box 80 and the rotating rod 81 is installed on the upper end. The rotating rod 81 passes through the upper box surface of the protection box 80 and is vertically connected to the filter assembly 7.

[0042] The protection box 80 can prevent the filtered paint from directly dripping onto the surface of the motor 82 to avoid damage to the motor 82 .

[0043] Furthermore,

[0044] The filter assembly 7 includes an inner filter cartridge 70, an outer filter cartridge 71, a blocking plate 72, and a support rod 73. The openings of the inner filter cartridge 70 and the outer filter cartridge 71 are both set upward, the filter holes of the inner filter cartridge 70 are larger than the filter holes of the outer filter cartridge 71, and the size of the outer filter cartridge 71 is larger than the inner filter cartridge 70. The outer side of the bottom of the outer filter cartridge 71 is vertically connected to the rotating rod 81, and a support rod 73 perpendicular to the bottom is installed on the inner side. The upper end of the support rod 73 is connected to the inner filter cartridge 70, and the inner filter cartridge 70 and the outer filter cartridge 71 are at the same height. The upper ends of the inner filter cartridge 70 and the outer filter cartridge 71 are both connected to the blocking plate 72 parallel to the bottom, and the blocking plate 72 has a hole matching the feed port at the position corresponding to the feed port 4.

[0045] The two ends of the support rod 73 are respectively connected to the outer side of the bottom of the inner filter cartridge 70 and the inner side of the bottom of the outer filter cartridge 71, connecting the inner filter cartridge 70 and the outer filter cartridge 71 as a whole, and the support rod 73 supports the inner filter cartridge 70. The opening ends of the inner filter cartridge 70 and the outer filter cartridge 71 are at the same height so that the blocking plate 72 can be horizontally installed at the opening ends of the inner filter cartridge 70 and the outer filter cartridge 71.

[0046] Furthermore,

[0047] The side plate 12 is provided with small holes in the vertical direction corresponding to the nozzles 62 one by one.

[0048] The small hole corresponding to the nozzle 62 ensures that the nozzle 62 can act on the filter assembly 7 when spraying, and can clean the blockage on the filter assembly 7.

[0049] Furthermore,

[0050] A sealing ring is provided between the protection box 80 and the rotating rod 81 .

[0051] It is ensured that the filtered paint will not enter the protection box 80 through the gap between the protection box 80 and the rotating rod 81 and damage the motor.

[0052] Furthermore,

[0053] The other end of the threaded connecting pipe 5 is connected to the air pressure pump through a pipeline.

[0054] Furthermore,

[0055] There is a sealing ring between the partition 63 and the device cover 2, and the sealing ring tightly clamps the partition 63.

[0056] When the partition 63 is lifted, the sealing ring can hold the partition 63, so that the sealing ring 63 will not fall down due to gravity.

[0057] The usage of the utility model is:

[0058] First, the threaded connection pipe 5 on the surface of the device cover 2 is connected to the pipeline through threads, the other end of the pipeline is connected to the pressure pump, and the feed port 4 is sealed and connected to the feed pipe.

[0059] After preparing for the above operation, hold the upper end of the partition 63 and lift it upwards, because the sealing ring between the partition 63 and the device cover 2 can tightly clamp the partition 63 and prevent the partition 63 from falling down. Start the pressure pump to transport gas to the air pipe 62 through the pipeline. The gas enters the inside of the device body 1 through the nozzle 63 to increase the internal air pressure of the device body 1. The pressure relief valve 3 can adjust the air pressure in the device to ensure that the optimal filtering air pressure can be achieved. After the adjustment is completed, put down the partition 63 and turn off the pressure pump.

[0060] Then start the motor 82 to drive the filter assembly 7 to rotate and add the paint to be filtered to the inner filter cartridge 70. The paint is first screened by the inner filter cartridge 70 and then finely screened by the outer filter cartridge 71. The inner filter cartridge 70 is provided inside to prevent larger impurities from clogging the filter holes of the outer filter cartridge 71. The blocking plate 72 can prevent the paint from overflowing the filter assembly 7 due to rotation when there is a lot of paint in the inner filter cartridge 70. The device accelerates the filtering speed of the paint by pressurizing and rotating centrifugation.

[0061] The filtered paint flows from the hollow horizontal plate 13 to the bottom of the device. After filtering for a period of time, the paint is stopped from being transported into the device, the discharge port 10 is opened, and the discharge of the paint begins.

[0062] If the filter is found to be clogged during filtration, the feeding is stopped, the speed of the motor is reduced, the partition 63 is lifted, the pressure pump is turned on, and the nozzle 62 sprays high-pressure airflow to clean the filter.

[0063] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
