Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide screening, in particular to a staggered screening device for titanium dioxide filtering. Background Art

[0002] Titanium dioxide (TiO2), scientifically known as titanium dioxide, is an important inorganic pigment with high chemical stability, heat resistance, weather resistance, and non-toxicity. Its excellent whiteness, gloss, refractive index, and hiding power make it widely used in various fields.

[0003] A search revealed a titanium dioxide screening device that is easy to clean (authorization publication number: CN 218190865 U). The device "comprises a housing and a screening drum rotatably connected to the upper half of the housing. The screening drum is open at the top, a feed pipe is provided above the housing, a drive unit is provided below the screening drum, and the outer circumference of the screening drum is provided with several sections. An air pump is fixedly connected to the inner top wall of the housing, and the air pump input end is located within the screening drum. A collection box is provided at the top of the housing, and the air pump output end communicates with the collection box. Two dust screens are hingedly connected to the top of the feed pipe. This utility model relates to the technical field of titanium dioxide screening. The device causes titanium dioxide to rotate within the screening drum, drawing extremely fine powder within the titanium dioxide into the collection box for collection, thereby reducing titanium dioxide waste. Furthermore, a first electric push rod controls the movement of the dust screen to shield the feed pipe, preventing extremely fine titanium dioxide powder from escaping into the external environment, thereby reducing environmental pollution."

[0004] Based on the above-mentioned related technologies, the applicant believes that the above-mentioned technology performs screening by rotating the screening drum. Since titanium dioxide is a powder, not a liquid, the screening effect of the rotating screening method is poor. At the same time, the above-mentioned technology lacks multi-stage screening, and the screening effect cannot meet the actual production and use needs. In response to the above problems, we have launched a staggered screening device for titanium dioxide filtration. Utility Model Content

[0022] In the above technical solution, considering that there is a method of screening by rotating the screening drum, since titanium dioxide is a powder, not a liquid, the screening effect of the rotating screening method is poor. At the same time, the above technology lacks multi-stage screening, and the screening effect cannot meet the needs of actual production use. In order to solve such problems, the specific operations are as follows:

[0023] Reference Figure 1 - Figure 4In a preferred embodiment, the output end of the motor 2 drives the rotating shaft 46 to rotate, and the rotation of the rotating shaft 46 drives the two cams 47 to rotate. The two cams 47 rotate in conjunction with the roller 48, and then the cam 47 presses the roller 48 downward, and the spring 44 is pressed by the coarse screen frame 43 and contracts. As the cam 47 rotates, the coarse screen frame 43 slides back and forth on the outside of the slide bar 42 under the tension of the spring 44. At this time, the staff puts the titanium dioxide into the interior of the screening box 1 through the feed hopper 3, and passes through the coarse screen frame 43 is screened by the up and down movement, and the titanium dioxide after screening falls on the top of the fine screen plate 6.

At the same time, compared with the rotating screening method, the screening method of rapid sliding up and down has higher screening efficiency, better screening effect, simple structure and strong practicality.

[0024] Reference Figure 1 - Figure 4 In a preferred embodiment, bulk rollers 9 are fixedly connected to the outside of the rotating shaft 46 at equal intervals. A collecting box 10 is slidably connected to the bottom of the inner wall of the screening box 1, and a handle 11 is fixedly connected to the front of the collecting box 10. A protective cover 12 is fixedly connected to the outside of the motor 2, and heat dissipation grooves 13 are equidistantly provided on the outside of the protective cover 12. A controller 14 is fixedly connected to the outside of the screening box 1 and on the side close to the motor 2, and the motor 2 is electrically connected to the controller 14. The bulk rollers 9 are provided to break up the titanium dioxide and evenly spread it on the top of the coarse screen frame 43. The titanium dioxide can be collected by the collecting box 10, and the motor 2 can be protected by the protective cover 12. The controller 14 is provided to facilitate the staff to control the opening and closing of the motor 2, and the operation is simpler.

[0025] Working principle: In actual use, the staff starts the motor 2, and the output end of the motor 2 drives the rotating shaft 46 to rotate. The rotation of the rotating shaft 46 drives the two cams 47 to rotate. The two cams 47 rotate in fit with the roller 48, and then the cam 47 presses the roller 48 downward, and the spring 44 is pressed by the coarse screen frame 43 and contracts. As the cam 47 rotates, under the tension of the spring 44, the coarse screen frame 43 slides back and forth on the outside of the slide rod 42. At this time, the staff puts titanium dioxide into the screening box 1 through the feed hopper 3, and the bulk roller 9 breaks up the titanium dioxide and evenly spreads it on the top of the coarse screen frame 43. After the coarse screen frame 43 moves up and down for screening, the screened titanium dioxide falls on the top of the fine screen plate 6. After screening by the fine screen plate 6, the titanium dioxide falls on the top of the fine screen plate 7. After screening by the coarse screen frame 43, the fine screen plate 6 and the fine screen plate 7, multi-stage screening can be achieved, and impurities of different sizes inside the titanium dioxide can be screened to meet production needs.
