Description

Technical Field

[0001] The invention relates to the technical field of water-based color paste processing, in particular to a filtering device for water-based color paste processing. Background Art

[0002] Water-based pigment pastes are high-concentration pigment dispersions using water as the dispersing medium. They are widely used in industries such as coatings, inks, textiles, and building materials. Compared to traditional solvent-based pigment pastes, water-based pigment pastes offer advantages such as environmental friendliness, low VOCs (volatile organic compounds), and ease of cleaning, meeting the green and environmentally friendly requirements of modern industry.

[0003] In the process of processing water-based color paste, filtration is a crucial step. By filtering, large particles in the water-based color paste can be filtered out and the quality of the color paste can be improved. However, the existing filtration devices all filter the color paste through the filter screen. The color paste only flows through the filter holes under the action of gravity, leaving large particles of impurities at the top of the filter screen, and the filtration efficiency is very low. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical difficulties and provide a filtering device for processing water-based color paste, which can increase the filtration speed by pressurizing, thereby greatly improving the processing efficiency.

[0005] The top end of the filter press is fixed with a filter press, and the bottom end of the filter press is fixed with a filter press, and the filter press is automatically closed by the filter press.

[0006] The rotating mechanism includes a supporting retaining ring fixedly connected to the upper end of the filter tank, the supporting retaining ring is rotatably connected to a ring gear, a gear meshing with the ring gear is rotatably connected inside the filter tank, and a first motor that drives the gear to rotate is fixedly connected inside the filter tank.

[0007] As an improvement, a connecting protrusion is fixedly connected to the upper end of the gear ring, and a fixing ring is fixedly connected to the upper end of the filter screen cylinder. The fixing ring is provided with a connecting hole that cooperates with the connecting protrusion.

[0008] As an improvement, the bottom surface of the filter cylinder is rotatably connected to a connecting seat, the upper end of the connecting seat is fixedly connected to a U-shaped brush rod, the bottom surface of the connecting seat is fixedly connected to a limiting slot, and the bottom surface of the filter tank is fixedly connected to a limiting plug that cooperates with the limiting slot.

[0009] As an improvement, the pressing mechanism includes a cam turntable rotatably connected to one side of the control bracket, one end of the cam turntable is rotatably connected to an eccentrically arranged adjustment block, the adjustment block is slidably connected to the inner wall of the adjustment frame, and a second motor that drives the cam turntable to rotate is fixedly connected to the control bracket.

[0010] As an improvement, a spring is fixedly connected between the pressing plate and the fixing plate, and a through hole is provided on one side of the blocking block on the pressing plate.

[0011] As an improvement, the side wall of the connecting sleeve is provided with a limiting sliding hole, and the side wall of the pressing plate is fixedly connected with a limiting sliding block in a sliding connection with the limiting sliding hole.

[0012] The advantages of the present invention compared with the prior art are: the pressing mechanism drives the pressing rod to drive the pressing plate to slide back and forth up and down, and the elastic pressing cover is pushed to undergo compression deformation during the downward pressing process of the pressing plate, so that the air in the elastic pressing cover is quickly compressed downward, and the water-based color paste is pushed to quickly pass through the mesh of the filter cylinder, greatly improving the filtration speed. After the pressing is completed, the pressing rod is lifted upward to open the exhaust hole, complete the pressure relief in the filter tank, and at the same time pull the elastic pressing cover to return to its initial state.
