After the lower part of the L-shaped spray pipe is flush with the upper part of the filter plate, repeat the above steps at least twice to achieve better flushing effect, which solves the problem that after filtering for a certain period of time, even if the filter cake is removed by the vibration device, a lot of impurities will still remain on the filter plate to block the filter holes, and the filter plate needs to be manually disassembled and manually flushed, which is a time-consuming, labor-intensive and cumbersome process.

[0018] 2.

[0037] Working principle: before use, ensure that the knife valve seat 11 is in a closed state, and then use a centrifugal pump to pump the edible oil along the feed pipe 7 into the lower cylinder 4 and fill it. Under the thrust of the pump, the edible oil circulates in the cylinder through the filter plate 26, and the large particles of impurities inside are first retained by the filter surface, thereby forming a filter cake layer. Under the action of the filter cake layer, the fine impurities in the edible oil can be further retained. At this time, the seepage discharge pipe 8 is opened for filtering. The edible oil enters the hollow interlayer of the filter plate 26 through the filter cake layer, and seeps into the seepage discharge pipe 8 for discharge, thereby filtering the impurities. After the filtration is completed, the feed pipe 7 is switched to the air compressor passage, and the air compressor is used to supply air into the filter. Under the action of the air pressure, the filter cake is squeezed dry, and then the vibration motor 9 is driven to run, and the slag discharge valve 6 is opened. The filter plate 26 is driven to move slightly through the vibration rod 28, so that the filter cake on the surface falls off and is discharged along the slag discharge valve 6. In order to further clean the filter plate 26, the knife valve is opened, and the first stepper motor 20 is driven to run. The first stepper motor 20 drives the ball screw 21 to rotate, so that it is transmitted with the first slider 235, and drives the cleaning mechanism 22 along the first guide rail seat 1 9, during the downward movement, the electric-controlled three-way valve 18 is switched to the high-pressure water pump passage, and the high-pressure water pump pumps the water in the external water tank into the connecting hose, so that it further enters the arc tube 223, and the water is sprayed onto the surface of the filter plate 26 through the multiple L-shaped spray pipes 228 at the lower end of the arc tube 223. During the spraying, after the lower part of the L-shaped spray pipe 228 is flush with the bottom surface of the filter plate 26, the first stepper motor 20 is reversed under the control of the program, and the cleaning mechanism 22 is controlled to move up again. During the upward movement of the cleaning mechanism 22, the second stepper motor 222 controls the forward screw rod 233 and the reverse screw rod 234. The screw rod 234 rotates synchronously, driving the arc tubes 223 on both sides and the L-shaped spray pipe 228 to move closer to the middle, and the middle position of the filter plate 26 is flushed. After the lower part of the L-shaped spray pipe 228 is flush with the upper part of the filter plate 26, the above steps are repeated at least twice to achieve a better flushing effect. After the flushing is completed, the movement mode of the cleaning mechanism 22 can be maintained in the flushing state, and the electric three-way valve 18 can be switched to a hot air blower, so that the L-shaped spray pipe 228 sprays hot air to the surface of the filter plate 26 to achieve hot air drying treatment, thereby quickly starting the subsequent filtering process.
