Among them, the driving device 6 provided in the embodiment of the utility model is a driving motor, which is driven by a 220V power supply; the transmission device 5 may include but is not limited to: a driving belt and a slide rail; the fixing device 4 may be a fixing plate; and the high-pressure spray gun 3 may be a spray gun with a high-pressure module or an ordinary spray gun connected to a high-pressure cleaning machine. The embodiment of the utility model is preferably an ordinary spray gun connected to a high-pressure cleaning machine, retaining the original high-pressure cleaning machine to save costs.

[0031] Specifically, the high-pressure spray gun 3 is connected to a high-pressure cleaning machine, and then sprays the high-pressure water flow generated by the high-pressure cleaning machine to the filter cloth of the belt vacuum filter for cleaning operation. The drive motor drives the transmission belt, and then drives the fixed plate and the high-pressure spray gun 3 to reciprocate on the slide rail to realize the cyclic cleaning function.

[0032] In some embodiments, the fixing plate and the high-pressure spray gun 3 can be set to move in a reverse direction after moving a certain distance (such as the width of the filter cloth) on the slide rail, and a limit device can also be installed on the slide rail to achieve the above setting. Figure 1 As shown, in the embodiment of the utility model, the limiter 2 is preferably installed on the edge of the slide rail, and when the fixed plate touches the limiter 2, the limiter 2 transmits the touch information to the drive motor through the data transmission line, so that the drive motor drives the transmission belt to drive the fixed plate to move in the opposite direction on the slide rail. Wherein, there are preferably two limiters 2, which are respectively installed on the two side edges of the slide rail. When the fixed plate moves to the right until it touches the limiter 2 on the right edge of the slide rail, the limiter 2 transmits the touch information to the drive motor, and the drive motor drives the transmission belt to drive the fixed plate to move to the left on the slide rail until it touches the limiter 2 on the left edge of the slide rail, and the reciprocating movement is cyclical, so as to achieve the effect of automatic cycle cleaning of the filter cloth.

Among them, the fixing device 4 provided in the embodiment of the utility model can be optionally a magnetic base, and the transmission device 5 can be optionally a cylinder 12, and the cylinder 12 is preferably a magnetic coupling cylinder, and the magnetic coupling cylinder includes: a main cylinder 12.1, which has a piston, and the piston is preferably a magnetic piston, so that the magnetic piston is connected to the magnetic base through magnetism, thereby controlling the movement of the base; and two auxiliary cylinders 12.2 and 12.3, which are placed on the left and right sides of the main cylinder 12.1, as shown in FIG. Figure 2 As shown, there are two air inlets 13, and the auxiliary cylinders 12.2 and 12.3 are connected to one air inlet 13 respectively. The auxiliary cylinders 12.2 and 12.3 have connecting ports (not shown) with the main cylinder 12.1 on both sides of the piston of the main cylinder 12.1, respectively, for supplying air to the main cylinder 12.1 in opposite directions. Figure 2 As shown, the driving device 6 provided in the embodiment of the utility model includes: an air source 8, which enters the auxiliary cylinders 12.2 and 12.3 through the air inlet 13, and then drives the magnetic piston in the main cylinder 12.1 to move, so that the main cylinder 12.1 drives the magnetic base to move, wherein the utility model embodiment preferably the air source 8 is instrument air; a solenoid valve 9, which is used when the magnetic base touches the limiter 2 respectively installed on the two side edges of the cylinder, the solenoid valve 9 receives the touch information transmitted by the limiter 2 through the data transmission line, and then switches and controls the instrument air to enter the auxiliary cylinders 12.2 and 12.3 corresponding to the air inlet 13 through another air inlet 13, so as to switch the moving direction of the magnetic piston in the main cylinder 12.1, and then drives the magnetic base to move back and forth, wherein, as Figure 2 As shown, the embodiment of the utility model provides a 24V power supply 11 to drive the solenoid valve 9 to switch the air inlet 13 through the relay 10.

[0035] In some embodiments, the instrument air enters the auxiliary cylinder 12.2 corresponding to the air inlet 13 via the solenoid valve 9, so that the auxiliary cylinder 12.2 sends air to the right into the main cylinder 12.1 via the connecting port on the right side of the main cylinder 12.1, thereby causing the magnetic piston in the main cylinder 12.1 to drive the magnetic base to move to the right until it touches the limiter 2 on the right edge of the cylinder, and then the limiter 2 transmits the touch information to the solenoid valve 9, and the solenoid valve 9 switches the instrument air to enter the auxiliary cylinder 12.3 corresponding to the air inlet 13 via another air inlet 13, so that the auxiliary cylinder 12.3 sends air to the left into the main cylinder 12.1 via the connecting port on the left side of the main cylinder 12.1, thereby causing the magnetic piston in the main cylinder 12.1 to drive the magnetic base to move to the left until it touches the limiter 2 on the left edge of the cylinder, and the reciprocating movement is repeated to achieve the effect of automatic cyclic cleaning of the filter cloth. In some embodiments, the pressure of the instrument wind can be adjusted, thereby adjusting the moving speed of the magnetic base and the high-pressure spray gun 3.

[0036] In some embodiments, Figure 2 As shown, the pneumatic cleaning device further includes: buffer pins 14, which are disposed on both sides of the cylinder 12 and are used to buffer the impact of the magnetic base on the two sides of the cylinder 12.

[0037] In some embodiments, the unidirectional moving distance of the fixing device 4 and the high-pressure spray gun 3 on the transmission device 5 is adjustable. Figure 1 and Figure 2 As shown, the embodiment of the utility model preferably uses a stopper 2 to limit the moving range of the high-pressure spray gun 3 and the fixed plate / magnetic base. Specifically, the position of the stopper 2 can be adjusted accordingly according to the specific conditions of the filter cloth. For example, when only a part of the filter cloth needs to be cleaned, the position of the stopper 2 can be adjusted accordingly according to the area of ​​the filter cloth that needs to be cleaned, thereby reducing the moving range of the fixed plate / magnetic base and the high-pressure spray gun 3 and saving cleaning costs.

[0038] In some embodiments, the high-pressure spray gun 3 can be movably mounted on the fixed plate / magnetic base and the position can be adjusted. Specifically, the position of the high-pressure spray gun 3 on the fixed plate / magnetic base can be adjusted accordingly according to the specific conditions of the filter cloth. The distance between the nozzle outlet and the filter cloth is called the gun distance. The smaller the gun distance, the greater the spray gun spray pressure, and the greater the impact of the water pressure on the filter cloth. Therefore, when the filter cloth pores are seriously blocked by colloidal substances such as sodium silicate and alumina, the position of the high-pressure spray gun 3 on the fixed plate / magnetic base can be appropriately extended forward to reduce the gun distance between the high-pressure spray gun 3 and the filter cloth of the belt vacuum filter, thereby increasing the impact of the water pressure on the filter cloth and improving the cleaning efficiency.

[0039] In some embodiments, see Figure 1and Figure 2 As shown, the high-pressure spray gun 3, the fixing device 4, the transmission device 5, the drive device 6 and the limiter 2 can be installed on the support member 1, and then the support member 1 is installed at the tail of the belt vacuum filter to facilitate cleaning of the filter cloth of the belt vacuum filter.
