Technical Field

[0001] The utility model relates to the technical field of printing and dyeing equipment, in particular to an environmentally friendly disperse dye filter press. Background Art

[0002] Filter press is a mechanical device used for solid-liquid separation, which is widely used in mining, metallurgy, chemical industry, environmental protection and other fields. Its main function is to separate the solid particles from the liquid in the mixture through pressure to achieve the separation of solid and liquid phases; in the production and use of disperse dyes, wastewater containing pigments, additives and other chemical substances will be generated. These wastewaters usually contain insoluble solid particles, which need to be effectively separated from the solid by a filter press.

[0003] When the filter press in the prior art filters disperse dyes, impurities are likely to remain on the filter plate, and these impurities are likely to clog the mesh holes on the filter plate, which not only affects the filtering effect of the filter plate, but also prolongs the filtering time and reduces production efficiency. Utility Model Content

[0008] By adopting the above technical scheme, disperse dyes enter the filter press box through the feed pipe, and the filter press roller is moved back and forth by starting the first cylinder to filter the disperse dyes on the surface of the filter plate. After the filtration is completed, the bottom plate is moved upward by the lifting assembly, and multiple push rods are entered into the mesh holes on the filter plate to squeeze out the impurities remaining in the mesh holes. Then, the cleaning plate is moved to the side of the impurity discharge pipe by starting the second cylinder to discharge the impurities from the impurity discharge pipe, thereby reducing the probability of impurities clogging the mesh holes of the filter plate, improving the filtering effect of the filter plate, and thus improving production efficiency.

Since the threaded rod is threadedly connected to the slider, and the slider is slidingly connected to the inner wall of the slide groove, the slider drives the bottom plate to move, making it easier for the push rod to push out impurities in the mesh of the filter plate.

[0011] Furthermore, a controller is provided on the side wall of the filter press box, and the controller is electrically connected to the first cylinder, the second cylinder and the driving motor.

[0012] By adopting the above technical solution, the controller is connected to the first cylinder, the second cylinder and the drive motor, so that the staff can control the filter press assembly, the cleaning assembly and the drive assembly through the controller.

[0014] By adopting the above technical solution, when the filter press roller squeezes the disperse dye, the spring cooperates with the filter press roller to improve the filtration effect of the disperse dye on the filter plate.

[0015] Furthermore, a rubber sheet is fixed to the top wall of the installation groove.

[0016] By adopting the above technical solution, the rubber sheet is made of rubber material, which is elastic and has a buffering effect on the filter plate, thereby reducing the wear between the upper surface of the filter plate and the top wall of the installation groove.

[0017] Furthermore, the upper surface of the bottom plate is arranged to be inclined downward toward one side of the discharge pipe.

[0018] By adopting the above technical solution, the inclined bottom plate allows the filtered disperse dye to flow to one side of the discharge pipe, which is conducive to the rapid discharge of the filtered disperse dye and reduces the probability of residual disperse dye on the bottom plate.

[0019] Furthermore, a wear-resistant pad is fixed to the bottom of the base plate.

[0020] By adopting the above technical solution, the wear-resistant pad is made of rubber material, and the material is elastic, which reduces the wear of the bottom of the base plate.

[0021] Furthermore, a flaring groove is provided at the intersection between the inner wall of the fixing groove and the side wall of the filter press box, and a trapezoidal baffle matching the flaring groove is hingedly connected to the side wall of the filter press box.

[0022] By adopting the above technical solution, the trapezoidal baffle protects the driving motor in the fixed groove, and the cross-sections of the expanded groove and the trapezoidal baffle are both trapezoidal, which is convenient for the staff to open and close the trapezoidal baffle to maintain the driving motor.
