Description

Technical Field

[0001] The invention relates to the technical field of filter press filter cloth cleaning, in particular to a filter press filter cloth cleaning mechanism. Background Art

[0002] Cleaning the filter cloth of the filter press is very important to maintain the working efficiency of the filter press and the service life of the filter cloth. When choosing the cleaning method, it is necessary to comprehensively consider factors such as the material of the filter cloth, the type and severity of dirt, and at the same time, the filter cloth must be checked after cleaning to ensure that the performance of the filter cloth is restored. The fully automatic plate and frame filter press can automatically clean the filter cloth by shaking the filter frame to assist the filter cake to fall off, and then perform automatic water flushing from both sides of the filter cloth. The flushing time depends on the degree of dirtiness of the filter cloth.

[0003] When a fully automatic plate and frame filter press cleans the filter cloth, water can generally only be used to automatically clean the front and back sides of the filter cloth, and the cleaning effect is poor. The filter cloth is usually used in a large area in a filter press. When the filter press is cleaned by water spraying, the water flow impact and the distribution of the cleaning liquid are uneven. For some sticky and fine dirt, the water spraying cleaning effect is not good enough, and the dirt may be embedded in the fiber gaps of the filter cloth, resulting in a decrease in the filtering performance of the filter cloth after cleaning.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing filter press cloth cleaning mechanism on the market, and even if it can be solved, it needs to be solved with the cooperation of external tools, which cannot achieve the desired effect.

[0030] The specific implementation of this embodiment is as follows: after cleaning the filter cloth once, waste water will remain in the soaking container 2101 and the ultrasonic cleaning machine 2106. In order to facilitate the next cleaning of the filter cloth, the first control valve 308 can be opened, and the waste water in the soaking container 2101 and the ultrasonic cleaning machine 2106 is discharged through the discharge pipe 307 and enters the water filter 303 through the connecting pipe 304. The specific model can be determined according to the processing capacity. The water filtered by the water filter 303 is stored in the liquid storage tank 301, and then by starting the water pump 309, the water pump 309 extracts the liquid and discharges it into the outlet pipe 302. When the second control valve 305 is opened, the liquid is added to the soaking container 2101 and the ultrasonic cleaning machine 2106 through the outlet pipe 302 and the water storage pipe 306, so that the waste water can be recycled. After the liquid in the soaking container 2101 and the ultrasonic cleaning machine 2106 is consumed to a certain extent, new liquid can be added. Corresponding chemical agents can be added to the liquid according to the needs of cleaning the filter cloth.
