Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide processing technology, specifically to a titanium dioxide coarse product roller grinding device with a shielding structure. Background Technology

[0002] Titanium dioxide is mainly used in the coatings industry. It is the white pigment with the strongest tinting strength, with excellent hiding power and color fastness. It is suitable for opaque white products. During the production of titanium dioxide, the coarse titanium dioxide needs to be processed by a roller mill to make it finer.

[0003] The existing titanium dioxide coarse product roller milling device lacks a shielding component at the feed inlet. When coarse titanium dioxide is added through the feed inlet, it is easy for the titanium dioxide to scatter, thereby polluting the external environment. If inhaled by workers, it can also cause physical harm.

[0004] In view of this, it is necessary to develop a titanium dioxide coarse product roller milling device with a shielding structure, so as to shield the titanium dioxide that is scattered during feeding. Utility Model Content

[0024] Please see Figure 1 , Figure 2 and Figure 3 A titanium dioxide coarse product roller grinding device with a shielding structure;

[0025] The device includes: a roller press box 1 and a shielding assembly. The shielding assembly is installed on the top of the roller press box 1. The shielding assembly includes a shielding shell 5, a slide groove 6, a sliding cover 7, a right-angle connecting plate 8, and a connecting spring 9. The shielding shell 5 is installed on the top of the roller press box 1. The slide groove 6 is symmetrically opened on the top of the shielding shell 5. The sliding cover 7 is installed on the top of the shielding shell 5 through the slide groove 6. The right-angle connecting plate 8 is installed on the outer side of the sliding cover 7. The connecting spring 9 is installed on the inner side of the bottom of the right-angle connecting plate 8, and the other end of the connecting spring 9 is fixed to both sides of the shielding shell 5. The top of the roller press box 1 is equipped with a feed inlet 4. The front of the roller press box 1 is equipped with a controller 3. The bottom of the roller press box 1 is equipped with a support frame 2. The bottom of the roller press box 1 is equipped with a discharge shell 19, and the discharge shell 19 penetrates the bottom of the support frame 2.

[0026] The roller press 1 provides space for the roller pressing of titanium dioxide. The titanium dioxide to be pressed enters the interior of the roller press 1 through the feed port 4. Since a shielding assembly is installed on the outside of the feed port 4, the sliding cover 7 in the shielding assembly is installed by the right-angle connecting plate 8 and the connecting spring 9. When titanium dioxide is added through the feed port 4, the shielding shell 5 and the elastically installed sliding cover 7 on the top shield the dust generated when the titanium dioxide is added. At the same time, after the addition is completed, the sliding cover 7 automatically closes immediately under the elastic force of the connecting spring 9, thereby reducing the titanium dioxide from flying to the outside and avoiding pollution to the environment. The controller 3 is used to control the switching of the electrical equipment in the device. The support frame 2 is used to support the roller press 1. The discharge shell 19 is used to discharge the titanium dioxide after roller pressing.

[0027] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 A titanium dioxide coarse product roller grinding device with a shielding structure;

[0028] Roller pressing shafts 13 are symmetrically installed inside the roller pressing box 1. Roller pressing friction sleeves 14 are installed on the outside of the roller pressing shafts 13. Pressing grinding plates 12 are symmetrically installed on the inner walls of both sides of the roller pressing box 1. A mounting shell 15 is installed on one side of the roller pressing box 1. A drive motor 16 is installed on one side of the mounting shell 15. A meshing first transmission gear 17 and a second transmission gear 18 are installed inside the mounting shell 15. The first transmission gear 17 and the second transmission gear 18 are respectively connected to the roller pressing shafts 13. A fixing plate 20 is installed on the inner wall of the top of the roller pressing box 1. A fixing pipe 21 is installed on the inner side of the fixing plate 20. Multiple high-pressure nozzles 22 are installed at the bottom of the fixing pipe 21. A connecting pipe 23 is connected to the outside of the fixing pipe 21. A transmission pipe 24 is installed at the top of the connecting pipe 23. A mounting plate 10 is installed on the front of the roller pressing box 1. An air pump 11 is installed on the top of the mounting plate 10. The output end of the air pump 11 is connected to the transmission pipe 24.

[0029] After the titanium dioxide powder enters the roller pressing chamber 1, the controller 3 controls the drive motor 16 to run. When the drive motor 16 is powered on, it drives the second transmission gear 18 to rotate, causing the roller pressing shafts 13, which are respectively connected to the first transmission gear 17 and the second transmission gear 18, to rotate relative to each other. This causes the titanium dioxide powder passing between the roller pressing shafts 13 to be pressed and ground by the roller pressing friction sleeve 14. The titanium dioxide powder passing between the roller pressing shafts 13 and the inner wall of the roller pressing chamber 1 is processed through friction with the grinding plate 12. This improves the processing efficiency of titanium dioxide. The high-pressure nozzle 22 is installed above the roller shaft 13 through the fixed pipe 21 and the fixed plate 20. The connecting pipe 23 is used to connect the two sets of fixed pipes 21. The controller 3 turns on the air pump 11, so that the air pump 11 is powered on and converts electrical energy into kinetic energy to compress the air. The compressed air is then transmitted through the transmission pipe 24 and finally sprayed out through the high-pressure nozzle 22. The roller friction sleeve 14 on the outside of the roller shaft 13 cleans the titanium dioxide that adheres to the outside during the rolling process, so as to avoid residue.

[0030] The working principle is as follows: First, the device is placed in the desired position using the support frame 2. The sliding cover 7 is opened, allowing the coarse titanium dioxide to enter the interior of the roller press box 1 through the feed port 4. With the relative rotation of the roller press shaft 13 and the friction of the roller press friction sleeve 14, the titanium dioxide passing through the roller press shaft 13 can be roller-pressed and polished. The titanium dioxide that has been roller-pressed is discharged through the discharge shell 19. The gas sprayed by the high-pressure nozzle 22 cleans the titanium dioxide adhering to the outside of the roller press shaft 13.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
