Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of titanium dioxide powder processing, in particular to an anti-caking crushing device for titanium dioxide powder processing. Background Art
[0002] Titanium dioxide is a white solid or powdered amphoteric oxide, which is considered to be the best performing white pigment in the world. Titanium dioxide is non-toxic, has optimal opacity, optimal whiteness and brightness, has strong adhesion, is not easy to undergo chemical changes, has a high melting point, and also has good UV shielding effect. In the titanium dioxide powder making process, agglomeration is easy to occur during powder production, which leads to the processing quality not being guaranteed and greatly reduces the quality of the product. Therefore, titanium dioxide powder processing equipment is usually equipped with a crushing structure for pre-treatment to prevent the direct processing of agglomerated powder.
[0003] However, this crushing structure in the processing equipment will undoubtedly increase the travel distance of the powder inside the processing equipment, affecting the overall production efficiency. At the same time, each processing equipment needs to be installed with a crushing structure, which will undoubtedly increase the equipment cost of the entire processing production line. In addition, the agglomerated titanium dioxide powder will also block the pneumatic transport pipeline, affecting the normal transportation of the powder. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] See also Figures 1 to 5 In an embodiment of the utility model, an anti-caking crushing device for titanium dioxide powder processing includes a pneumatic conveying pipe 1, a grinding structure 2 and a connecting frame 3. The pneumatic conveying pipe 1 includes a pipe body 101, a spiral tube 104 is rotatably installed in the middle of the pipe body 101 through a sealed bearing, and an auger blade 106 is fixedly wound and installed on the inner wall of the spiral tube 104; the grinding structure 2 includes a powder guide column 203, a grinding body 204 is fixedly installed on the bottom side of the powder guide column 203, the powder guide column 203 and the grinding body 204 are rotatably installed inside the spiral tube 104, and the side surface of the powder guide column 203 and the inner side of the auger blade 106 slide against each other; the connecting frame 3 is relatively fixedly sleeved on the outer surface of the spiral tube 104.
[0038] Specifically, the pipe body 101 is used as a part of the entire pneumatic transport channel for titanium dioxide powder and is installed in front of the entrance of each processing equipment. When entering the spiral tube 104, the guide channel composed of the auger blade 106 and the powder guide column 203 slows down the travel speed. The spiral tube 104 and the powder guide column 203 rotate in opposite directions relative to each other, and are squeezed and continuously sent to the location of the grinding body 204 by the guide channel, thereby limiting the amount of titanium dioxide powder that needs to be crushed and ground by the grinding body 204 at a time, improving the crushing effect, and avoiding clogging of the grinding body 204. The titanium dioxide powder is squeezed, ground and crushed by the side surface of the grinding body 204 and the inner wall of the spiral tube 104. Only the ground titanium dioxide powder can enter the interior of the processing equipment, thereby avoiding the presence of lumps in the processed titanium dioxide powder, which affects the processing effect. Example 1
[0039] like Figure 2 and Figure 4 As shown, in this embodiment, the grinding structure 2 also includes a No. 1 motor 201, a suspension rod 202 and grinding teeth 205. The No. 1 motor 201 is fixedly mounted on the upper surface of the motor mounting seat 103; the upper end of the suspension rod 202 passes through the motor mounting seat 103 and is fixedly connected to the output end of the No. 1 motor 201, and the lower end of the suspension rod 202 penetrates into the interior of the pipeline body 101 and is fixedly connected to the upper end of the powder guide column 203; there are several grinding teeth 205, and each grinding tooth 205 is fixedly mounted on the side surface of the grinding body 204 in a circular shape with equal angles. The grinding body 204 is composed of two upper and lower conical cylinders with different conical surface angles fixedly connected to each other.
[0040] In this embodiment, the powder guide cylinder 203 is rotated by the No. 1 motor 201 through the suspension rod 202, thereby driving the grinding body 204, and the corrugated structure formed by the grinding teeth 205 on the side surface of the grinding body 204 is used to grind and crush the powder. At the same time, the gap between the conical cylinder of the upper part of the grinding body 204 and the inner wall of the spiral tube 104 is larger than the gap between the conical cylinder of the lower part of the grinding body 204 and the inner wall of the spiral tube 104. The lumps in the powder are first initially ground into fine lumps through the large gap, and then completely ground into powder through the small gap. Through double grinding, first coarse and then fine, the grinding and crushing effect is improved.
[0041] like Figure 1 and Figure 5 As shown, in this embodiment, the pneumatic conveying pipeline 1 also includes an outer gear ring 107, which is fixedly sleeved on the lower edge of the outer surface of the spiral tube 104.

One side of the No. 1 gear 307 is meshed with the No. 2 gear 308 that is rotatably interwoven and installed on the lower edge of the motor mounting plate 305, and one side of the No. 2 gear 308 is meshed with the outer gear ring 107.
[0042] In specific implementation, the No. 1 gear 307 is rotated by the No. 2 motor 306, and then the No. 1 gear 307 is driven by the No. 2 gear 308, and the outer gear ring 107 is used to rub the spiral tube 104 to rotate in the opposite direction relative to the powder guide column 203 and the grinding body 204, thereby driving the auger blade 106 to push the powder in the spiral tube 104 to move forward. Example 2
[0043] On the basis of the first embodiment, in order to compensate for the problem that when the coil 104 is rotatably installed in the middle of the pipe body 101 in the first embodiment, the pipe body 101 parts at the upper and lower ends of the coil 104 are in relative motion, affecting the independent rotation stability of the coil 104.
[0044] like Figure 5As shown, in this embodiment, the pneumatic conveying pipeline 1 also includes a flange interface 102, a motor mounting base 103 and a connecting base 105.

[0045] During specific implementation, the entire device is used as part of the powder pneumatic transport channel and connected to the pneumatic conveying system through the flange interfaces 102 at the upper and lower ends of the pipe body 101. The two connecting base plates 105 that are relatively movable due to the rotational installation of the spiral tube 104 are connected to each other through each connecting rod 301, so that the two connecting base plates 105 are relatively fixedly connected. At the same time, each connecting rod 301 is processed through each reinforcement ring 304, and an installation foundation is provided for the No. 2 motor 306.
