Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide production, in particular to a titanium dioxide pressure filtration and water washing device. Background Technique

[0002] Titanium dioxide is an important inorganic chemical product and has important uses in industries such as coatings, inks, paper making, plastic rubber, chemical fibers, and ceramics. During the production process of titanium dioxide, the slurry needs to be filtered and then subjected to processes such as water washing and bleaching.

[0003] When filtering titanium dioxide, a pressure filtration device is required. For example, a slurry pressure filtration device for titanium dioxide production with a patent publication number of CN214763650U. When in use, by starting the hydraulic component to squeeze and contract the filter cylinder through the pressing plate, the water molecules in the material inside it can be quickly filtered out, and fall to the bottom of the cylinder through the filter plate for collection, improving the efficiency and quality of filtering the liquid. And by starting the motor to drive the eccentric top block to rotate, during its rotation, it sometimes contacts the convex seat on the second filter plate, and through the convex seat, one end of the second filter plate is pushed to tilt up. Therefore, the thorn cone performs up and down insertion and jolting operations on the first filter plate, making the extruded slag condensed on the first filter plate loose, avoiding blockage of the first filter plate during later use and affecting the later pressure filtration quality.

[0004] However, during the pressure filtration process of titanium dioxide by the above device, in order to ensure the penetration of the filter plate and facilitate the cleaning of the slag on the surface of the filter plate, the method of using a thorn cone to penetrate the filter plate is adopted, making the slag on the upper surface of the filter plate loose for subsequent cleaning of the slag. However, with this method, the thorn cone will damage the voids on the surface of the filter plate during the insertion process, reducing the service life of the filter plate.

[0005] In view of this, the utility model proposes a titanium dioxide pressure filtration and water washing device to solve this problem. Content of the Utility Model
