Description

Technical Field

[0001] The utility model belongs to the field of sludge processing equipment, and in particular relates to a sludge filter press device. Background Art

[0002] Sludge is produced in the process of sewage treatment. Since there is still a lot of water in the sludge, if it is not treated or improperly treated and discharged, it is not conducive to the incineration of the sludge and will cause secondary pollution to the water and air. Plate and frame filter presses or belt filter presses are often used for sludge dehydration treatment. The sludge is squeezed and filtered into a cake shape and then incinerated.

[0003] However, the current filter press equipment applies a fixed pressure to the sludge regardless of its viscosity, which not only affects the quality and efficiency of sludge treatment, but also damages the filter press equipment and reduces its service life.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0007] The filter press mechanism comprises a pressing roller and cylinders arranged on both sides of the pressing roller. The cylinders drive the pressing roller to move up and down to adjust the pressure on the sludge on the filter belt.

[0008] The first conveying mechanism comprises two first rotating rollers, a conveying belt is arranged between the two first rotating rollers, and a rotating motor is arranged on at least one of the two first rotating rollers.

[0011] A water reservoir is provided on one side of the second conveying mechanism, and a water pipe is provided between the water reservoir and the water collecting tank for conveying the filtrate in the water collecting tank to the water reservoir for collection and treatment.

[0012] The frame is provided with a scraper, which is matched with the filter belt and is used to scrape the mud cake on the filter belt and the sludge remaining on the filter belt and drop them into the material receiving frame.

[0013] A material receiving frame is provided on one side of the second conveying mechanism for collecting the mud cake after filter pressing and the sludge remaining on the filter belt.
