[0002] The filter chamber of the box filter press consists of a flat filter plate and a hollow filter frame, and the filter cloth is fixed on the plate frame. The principle of the box filter press is that under the pressure of the feed pump, the material liquid to be filtered is sent into each filter chamber, and the solid and liquid are separated through the filter medium, forming filter residue on the filter cloth until the filter chamber is filled to form a filter cake. The filter cloth can mainly realize solid-liquid separation, so it is necessary to clean and replace the filter cloth regularly, and it is necessary to use a cleaning device to clean the outer wall of the filter cloth.

[0003] The filter cloth is mainly used for solid-liquid separation, so there will be more solid impurities attached to the outer wall of the filter cloth. After replacement, it is necessary to use a cleaning device to clean the filter cloth. Most people manually control the position of the nozzle to clean the filter cloth in turn. The number of filter cloths is relatively large, which will increase the working time and burden of the staff. The cleaning device is not practical enough. At the same time, due to the use of a high-pressure spray gun, the impact of the water flow is relatively large. After the water contacts the filter cloth, it will splash around, which not only causes water waste, but also causes the surrounding ground to be wet, requiring subsequent ground cleaning. Therefore, it is particularly important to design a cleaning device for the outer wall of the filter cloth of a box filter press. Utility Model Content

After the two pushing plates 10 are in contact, the four sides of the cleaning seat 1 can be wrapped.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, a movable block 15 is threadedly sleeved on one end of the screw rod 14, a cleaning pipe 16 is inserted and connected to one end of the bellows 13, a servo motor 18 is arranged on one side of the top plate 5, and the screw rod 14 rotates inside the top plate 5. The utility model provides a cleaning device for the outer wall of the filter cloth of a box-type filter press. By arranging the bellows 13, the cleaning pipe 16, the servo motor 18 and the movable groove 11, after starting the servo motor 18, it will drive the screw rod 14 to rotate synchronously, so that the movable block 15 can be moved left and right at one end of the screw rod 14, and the spray head 17 can be adjusted to move left and right, thereby increasing the cleaning range of the filter cloth 4 of the box-type filter press.

[0026] Working principle: The filter chamber of the box filter press consists of a flat filter plate and a hollow filter frame, and the filter cloth is fixed on the plate frame. The principle of the box filter press is that under the pressure of the feed pump, the material liquid to be filtered is sent into each filter chamber, and the solid and liquid are separated by the filter medium, and filter residue is formed on the filter cloth until the filter chamber is filled to form a filter cake. The filter cloth can mainly realize solid-liquid separation, so it is necessary to clean and replace the filter cloth regularly, and it is necessary to use a cleaning device to clean the outer wall of the filter cloth. At this time, it is necessary to take out the filter cloth 4 of the box filter press and place it in turn. The inside of the placement plate 3 is placed for the purpose of cleaning multiple filter cloths 4 of the box filter press at the same time. Since the water collecting box 7 is located at the bottom of the top plate 5 and the width of the water collecting box 7 is greater than the width of the top plate 5, the water collection area is wider. The water collecting box 7 can also be taken out from the bottom of the cleaning seat 1. The inside of the water storage cylinder 6 is injected with water used for cleaning. A water pump is installed on one side of the L-shaped guide pipe 12. After the water pump is manually started, the water inside the water storage cylinder 6 can be guided to the surface of the filter cloth 4 of the box filter press through the bellows 13 and the spray head 17. The spray head 17 is With a high-pressure spray gun, the force of the spraying is relatively large, and the cleaning effect will be better. Under the impact of water and the solid impurities on the surface of the filter cloth 4 of the box filter press, they can be washed down, so the surface of the filter cloth 4 of the box filter press can be cleaned. When cleaning the filter cloth 4 of the box filter press, the staff can move the two push plates 10 inward. After the two push plates 10 are in contact, the surroundings of the cleaning seat 1 can be wrapped to avoid water splashing everywhere during cleaning. The used water can be more comprehensively collected by the water collection box 7, and the fixed rods 9 slide inside the movable grooves 11 respectively. , so the distance between the two push plates 10 can be adjusted. After starting the servo motor 18, it will drive the screw rod 14 to rotate synchronously, so that the movable block 15 can move left and right at one end of the screw rod 14, and the spray head 17 can be adjusted to move left and right, thereby increasing the cleaning range of the box filter press filter cloth 4. The bellows 13 is composed of foldable corrugated sheets combined along the folding and telescopic direction. When the cleaning tube 16 moves, the bellows 13 will be stretched, stretched and compressed by force. Therefore, the movement of the movable block 15, in conjunction with the deformation of the bellows 13, can normally transport water.
