[0002] In the production and processing of titanium dioxide, the control of salt treatment density is a key step that directly affects the quality and performance of the final product. During the salt treatment process, various salts are usually added as treatment agents, such as potassium salts, phosphate salts, aluminum salts, etc. These salts can effectively adjust the density and properties of the slurry.

[0003] After searching, the announcement number is CN206203904U, and the name is a salt treatment density control tank for preparing titanium dioxide, which includes a tank body. Through research and analysis, it is found that although the liquid level meter can automatically detect and monitor the liquid level of the slurry in the tank body, there are still the following shortcomings to a certain extent.

The output end of the stirring motor 4 is fixedly connected to a rotating rod 6, and a stirring blade 7 is fixedly sleeved on the surface of the rotating rod 6. By setting the rotating rod 6 and the stirring blade 7, the rotating rod 6 and the stirring blade 7 can be driven by the stirring motor 4 to rotate, thereby stirring the material in the treatment box 1. A discharge valve 5 is fixedly installed at the bottom of the treatment box 1, and a grinding and feeding assembly 2 is installed on the top of the left and right sides of the treatment box 1.

The surface of the movable rod 213 is respectively sleeved with a first spiral blade 202, an angle sensor 203, a grinding sleeve 211 and a second spiral blade 210. By providing the angle sensor 203, the rotation angle of the movable rod 213 can be monitored in real time. Since the pitch of the second spiral blade 210 is fixed, the amount of material conveyed by the second spiral blade 210 can be controlled according to the rotation angle of the second spiral blade 210.

The top of the support plate 201 is fixedly connected with a stabilizing frame 208. By setting the stabilizing frame 208, the fixed installation requirements of the feed cylinder 212 and the feed pump 207 can be met.

[0022] See also Figure 3 and Figure 4The outer ring of the feeding cylinder 212 is fixedly connected to the connection of the stabilizing frame 208, and the bottom of the feeding pump 207 is bolted to the top of the stabilizing frame 208;

[0023] See also Figure 3 and Figure 4 The end of the movable rod 213 away from the conveying motor 204 passes through the feeding barrel 212. The first spiral blade 202, the grinding sleeve 211 and the second spiral blade 210 are all located in the feeding barrel 212. By setting the first spiral blade 202, it can rotate together with the movable rod 213, thereby continuously transmitting the introduced material to the grinding tank 205.

[0024] See also Figure 3 and Figure 4 The grinding groove 205 is in the shape of a truncated cone, and the grinding groove 205 is adapted to the grinding sleeve 211. By setting the grinding groove 205 and the grinding sleeve 211, the material in the grinding groove 205 can be ground when the grinding sleeve 211 rotates. Moreover, due to the truncated cone design of the grinding groove 205, the material can be ground step by step, and the overall grinding uniformity is better.

[0027] In practical applications, a drop-in liquid level sensor can be used to monitor the material level in the processing box 1;

[0028] In actual application, since the feeding barrel 212 and the feeding head 209 are set at an angle, after the conveying motor 204 stops working, the slurry will naturally remain in the feeding head 209 and the feeding barrel 212 under the action of gravity, and there will be no dripping phenomenon when adding materials through traditional pipelines, which is more in line with actual usage needs.

[0029] When in use, all components are in the initial installation state, the feeding end of the feeding pump 207 is connected to the external material source, and according to the actual feeding accuracy requirements, the feeding head 209 of appropriate specifications is selected and fixedly installed on the feeding barrel 212, the feeding pump 207 is controlled to work, and the hard material slurry is passed from the feeding pipe 206 into the feeding barrel 212, and the feeding motor 204 is synchronously controlled to work, driving the movable rod 213 to rotate, so that the angle sensor 203, the grinding sleeve 211 and the second spiral blade 210 rotate synchronously, wherein the angle sensor 203 rotates , the material is transported to the grinding trough 205, and the rotating grinding sleeve 211 is used to grind the material. The rotation of the second spiral blade 210 will transport the ground material to the feed head 209, and finally it will be discharged from the upper port of the feed head 209 and fall into the processing box 1. Then the stirring motor 4 is controlled to work, driving the rotating rod 6 and the stirring blade 7 to rotate, and the material in the processing box 1 is mixed and stirred. After the processing is completed, the discharge valve 5 is opened, and the material in the processing box 1 will be discharged through the discharge trough 8 and the discharge valve 5.
