Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide grinding technology, specifically to a titanium dioxide grinding device with a dispersing function. Background Technology

[0002] Titanium dioxide is an inorganic chemical pigment, mainly composed of titanium dioxide. It can be used in coatings, inks, papermaking, chemical fibers, ceramics and other fields. By grinding titanium dioxide using material processing methods, its particle characteristics can be optimized to fully realize its functional value as a white pigment. In order to ensure the uniformity of titanium dioxide particle size after grinding, titanium dioxide agglomerates are pre-dispersed before grinding, and the particle size is refined by grinding impeller to ensure uniformity. Therefore, this utility model proposes a titanium dioxide grinding equipment with dispersion function. Summary of the Invention

[0003] The purpose of this invention is to provide a titanium dioxide grinding device with a dispersing function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a titanium dioxide grinding device with dispersion function, comprising a feeding chamber, a grinding chamber, and a filtering chamber. The feeding chamber has a feeding cavity inside and a feeding hopper communicating with the feeding cavity at its top. A conical coarse screen is installed inside the feeding cavity, and a dispersing disc is rotatably installed at the bottom of the coarse screen. The grinding chamber has a grinding cavity inside and a grinding disc is rotatably installed within the grinding cavity. The top of the grinding cavity communicates with the bottom of the feeding cavity through a channel, and the side of the grinding cavity communicates with the filtering chamber through a discharge pipe. A fine screen is inclinedly installed on the filtering chamber, and the lower part of the fine screen communicates with a conveying channel opened on the side of the filtering chamber through a slot. A spiral conveying rod is rotatably installed within the conveying channel, and the top of the conveying channel communicates with the feeding cavity.

[0005] Preferably, the dispersion disc has multiple blade-shaped protrusions along its outer edge at the top, and a rotating shaft is connected to the center of the dispersion disc, which is driven to rotate by a motor located at the top of the feeding chamber. The high-speed rotation of the dispersion disc generates strong shearing force to pre-disperse the titanium dioxide clumps.

[0006] Preferably, the outer ring of the grinding disc is provided with multiple blades at an angle, and the blades are slidably connected to the inner wall of the grinding chamber. During the rotation of the blades, the titanium dioxide is ground by friction between the blades and the inner wall of the grinding chamber, and under the action of centrifugal force from the rotation of the blades, it moves towards the outside of the grinding chamber and finally falls from the discharge pipe into the filter chamber for filtration.

[0007] Preferably, a collection trough is provided inside the filter chamber below the fine screen. A motor for driving the grinding disc to rotate is provided at the bottom of the grinding chamber, and a motor for driving the screw conveyor to rotate is provided on the material conveying channel.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by rotating the dispersion disc in the feeding chamber, the titanium dioxide clumps are cut and broken, fall into the grinding chamber, and enter the filtration chamber for filtration under the grinding of the rotating grinding disc, collecting titanium dioxide with standard particle size, and titanium dioxide that does not meet the standard slides down the fine screen into the conveying channel, and falls back into the grinding chamber for further grinding under the rotation of the spiral conveyor rod, so that the particle size of the titanium dioxide reaches the standard.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Referring to Figures (1-3), a titanium dioxide grinding device with a dispersion function includes a feeding chamber 1, a grinding chamber 2, and a filtering chamber 3. The feeding chamber 1 has a feeding cavity 14 inside, and a feeding hopper 11 communicating with the feeding cavity 14 is provided at the top. A conical coarse screen 12 is provided in the feeding cavity 14, and a dispersing disc 13 is rotatably provided at the bottom of the coarse screen 12. The grinding chamber 2 has a grinding cavity inside, and a grinding disc 21 is rotatably provided in the grinding cavity. The top of the grinding cavity is connected to the bottom of the feeding cavity 14 through a channel, and the side of the grinding cavity is connected to the filtering chamber 3 through a discharge pipe 23. A fine screen 31 is inclinedly provided on the filtering chamber 3. The lower part of the fine screen 31 is connected to a conveying channel opened on the side of the filtering chamber 3 through a slot, and a spiral conveying rod 32 is rotatably provided in the conveying channel. The top of the conveying channel is connected to the feeding cavity 14. The dispersing disc 13 has multiple blade-shaped protrusions along its outer edge. A rotating shaft is connected to the center of the dispersing disc 13, and this rotating shaft is driven to rotate by a motor located at the top of the feeding chamber 1. The grinding disc 21 has multiple blades 22 inclinedly arranged on its outer ring, and the blades 22 are slidably connected to the inner wall of the grinding chamber 2. A collection trough is provided inside the filter chamber 3, below the fine screen 31.

[0015] In use, the titanium dioxide to be ground is poured into the feed hopper 11 from the feed hopper 11. The dispersion disc 13 is driven by the motor to rotate, breaking and shearing the titanium dioxide clumps, so that the titanium dioxide passes through the coarse screen 12 into the feed chamber 14, and enters the grinding chamber 2 from the bottom of the feed chamber 14 through the channel. The grinding disc 21 is driven by the motor to rotate to grind the titanium dioxide. The ground titanium dioxide falls through the discharge pipe 23 onto the fine screen 31 on the filter chamber 3 for screening and filtration. The titanium dioxide that cannot pass through the fine screen 31 slides along the fine screen 31 into the conveying channel, and is transported back into the feed chamber 14 by the screw conveyor 32, and falls back into the grinding chamber 2 for grinding again.
