Description

Technical Field

[0001] The utility model relates to the field of filter press equipment, in particular to a filter press which is easy to clean. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to make the liquid seep out, thereby achieving solid-liquid separation. It is one of the commonly used solid-liquid separation equipment. Its working principle is mainly to use the pressure difference to separate solid particles from liquid. Filter presses are widely used in many industries, such as chemical industry, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics and environmental protection. In addition, it is also used for construction site sludge dewatering, sand washing wastewater treatment, mine solidification dry drainage, papermaking, leather, animal husbandry, aquatic products, chemical and other industries, as well as river sludge, reservoir sludge, lake sludge and other sludge dewatering, as well as municipal sludge dewatering, urban sewer and other sewage treatment.

[0003] Due to limitations in structural design and material selection, traditional filter presses are difficult to clean and maintain during use because of the small gaps between filter plates and inside the filter chamber, which easily accumulates residual materials and dirt. This not only increases the labor intensity of operators, but may also lead to a decline in the performance of the filter press and even affect its service life. For this reason, we propose a filter press that is easy to clean. Utility Model Content

[0027] The sliding mounting structure 11 is arranged on both sides of the mounting bracket 7, and is used to drive the cleaning device 12 to move up and down to expand its cleaning area. The water tank 8 is used to store cleaning water and provide a water source for the cleaning operation of the filter press. The hydraulic cylinder 10 is the actuator of the sliding mounting structure 11, and realizes various cleaning sliding actions through the pressure of the liquid.

[0028] Furthermore, the mounting bracket 7 is an inverted U-shaped structure that is symmetrical on both sides, and a hydraulic pump controller 20 is fixedly connected to the front side of the water tank 8 , and the hydraulic pump controller 20 is electrically connected to the hydraulic pump 9 .

[0029] Furthermore, the sliding mounting structure 11 includes a sliding clamp 13, a connecting parallel plate 14 and a connecting plate 15. The sliding clamp 13 is slidably clamped on both sides of the mounting bracket 7. Two parallel connecting parallel plates 14 are fixedly connected between the two sliding clamps 13. The connecting parallel plates 14 are fixedly connected on both sides.

[0030] Furthermore, both ends of the sliding clamp 13 are U-shaped, and a connecting block is fixedly connected to the side of the sliding clamp 13 away from the mounting bracket 7. The connecting block is fixedly connected to the push rod of the hydraulic cylinder 10. The distance between the two connecting parallel plates 14 is greater than the thickness of the filter plate. The lower ends of the two connecting plates 15 are fixedly connected to an arc-shaped opposing plate 16, and a water flow channel is provided inside the arc-shaped opposing plate 16.

[0034] Working principle: When the device is in operation, the operator can execute commands to the filter press through the control system 4, drive the oil cylinder body 2 through the driving device 3, so that the pressing plate presses the filter structure 6, and injects the liquid to be filtered into the liquid inlet 5, and filters it through the filter structure 6. When the filtering work is completed and the filter plate needs to be cleaned, first, the oil cylinder body 2 is contacted to press the filter structure 6, and the filter plates in the filter structure 6 are moved one by one to the bottom of the mounting bracket 7. By turning on the controller of the hydraulic cylinder 10, the hydraulic cylinder 10 is controlled to push the hydraulic push rod of the hydraulic pump 9 downward under the control of the hydraulic pump 9, so as to drive the sliding clamps 13 on both sides to move downward, and the sliding clamps 13 move downward to push the two arc-shaped plates 16 of the port downward. The filter plate 16 is moved so that the gap between the two arc-shaped plates 16 is inserted into the filter plate to be cleaned. At the same time, the hydraulic pump controller 20 controls the water pump 19 to pump water and pressurize the water tank 8, so that the pressurized water flow is transmitted to the water spray head 17 through the connecting water pipe 18, so that the water spray head 17 rinses the filter plate inserted between the two arc-shaped plates 16. When the sliding clamping plate 13 drives the arc-shaped plates 16 to the lowermost end, the hydraulic pump controller 20 controls the sliding mounting structure 11 to move upward, so that the arc-shaped plates 16 are upward again for secondary cleaning of the filter plate. After cleaning, the filter plate can be moved to one side, and the second filter plate to be cleaned can be moved to the bottom of the cleaning device 12. In this cycle, multiple filter plates can be cleaned, which not only saves labor costs but also greatly shortens the cleaning time.
