Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide screening, in particular to a nuclear titanium dioxide screening device which is easy to clean. Background Art

[0002] Titanium dioxide is an important inorganic material in the chemical industry and is widely used in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. During the production of titanium dioxide, it is finally crushed by a crushing equipment to transform the titanium dioxide into powder. The crushed titanium dioxide is then screened to obtain titanium dioxide of suitable particle size. A titanium dioxide screening device is used when screening titanium dioxide.

[0003] For example, a Chinese patent with the authorization announcement number CN218190865U discloses a titanium dioxide screening device that is easy to clean, including a shell and a screening cylinder rotatably connected to the upper half of the shell, the screening cylinder is set with an opening at the top, a feed pipe is passed through the top of the shell, a driving part is set below the screening cylinder, and a plurality of screening parts are set on the outer peripheral surface of the screening cylinder. An air pump is fixedly connected to the top wall of the shell, the input end of the air pump is located in the screening cylinder, a collection box is set on the top of the shell, the output end of the air pump is connected to the collection box, and two dust-proof nets are hinged on the top of the feed pipe. The titanium dioxide rotates in the screening cylinder, so that the too small powder in the titanium dioxide is sucked into the collection box for collection, which reduces the waste of titanium dioxide, and the first electric push rod controls the movement of the dust-proof net to shield the feed pipe, preventing too small titanium dioxide powder from moving into the external environment, reducing environmental pollution.

[0004] The above patent drives the titanium dioxide powder of qualified size to pass through the screening net and move into the collecting shell under the action of centrifugal force through the rotation of the screening drum. However, the above patent lacks a cleaning mechanism to clean the screening net. The screening net is easily blocked by larger titanium dioxide powder, which affects the screening efficiency of titanium dioxide. Moreover, when a certain amount of titanium dioxide powder is stored in the screening drum, the titanium dioxide powder in the drum rotates during the rotation of the screening drum. The two are basically relatively still, which is not conducive to the titanium dioxide powder of qualified size to quickly pass through the screening net, further affecting the screening efficiency of titanium dioxide powder.

[0035] Through the coordinated use of the driving mechanism, the sliding assembly and the return spring 4, the screening box 2 can be driven to vibrate back and forth in the shell 1, thereby driving the titanium dioxide contained in the screening box 2 to vibrate, which is beneficial for the titanium dioxide of qualified size in the screening box 2 to quickly pass through the screening plate 3, and can improve the screening efficiency of the titanium dioxide.

[0036] The driving mechanism includes a driving motor 5 fixedly mounted on one side of the shell 1, the output end of the driving motor 5 is fixedly connected to a main gear 6, the outer surface of the main gear 6 is meshed with a sub-gear 7, the sub-gear 7 is fixedly connected to a rotating shaft 8, the rotating shaft 8 is rotatably installed on the shell 1, and one end of the rotating shaft 8 located inside the shell 1 is fixedly connected to a cam 9.

[0037] The cleaning mechanism includes a rotating shaft 10 that is rotatably installed on the housing 1, and a cleaning frame 11 is fixedly connected to the bottom end of the rotating shaft 10. The transmission assembly includes a main pulley 12 and a secondary pulley 13.

A transmission belt 14 is arranged between the outer surfaces of the main pulley 12 and the secondary pulley 13.

[0038] Through the setting of the transmission component, during the operation of the driving mechanism, kinetic energy is transmitted to the cleaning mechanism, driving the cleaning frame 11 to rotate to move the titanium dioxide accumulated on the top of the screening plate 3, preventing large-sized titanium dioxide from clogging the screening plate 3, and facilitating titanium dioxide of qualified size to pass through the screening plate 3 smoothly, thereby further improving the screening efficiency of titanium dioxide.

[0039] A slot 15 is provided on the front side of the screening box 2 , and an inserting plate 16 is movably inserted into the slot 15 , and the inserting plate 16 is fixedly connected to the screening plate 3 .

[0040] A limiting assembly for limiting the position of the screening plate 3 is arranged on the front of the screening box 2, and the limiting assembly includes a supporting block 17 fixedly mounted on the front of the screening box 2, a vertical rod 18 movably penetrates the supporting block 17, and a limiting block 19 is fixedly connected to the bottom end of the vertical rod 18, and an extrusion spring 20 is arranged between the limiting block 19 and the opposite side of the supporting block 17 and on the outside of the vertical rod 18.

[0041] A collecting box 21 is movably inserted into the front of the shell 1 , and an upper hopper 22 is arranged on the top of the shell 1 , and a baffle movably penetrates the upper hopper 22 .

[0042] The sliding assembly includes a slide rail 23 fixedly mounted on the top of the inner wall of the shell 1, and a slider 24 is slidably connected inside the slide rail 23. The bottom of the slider 24 is fixedly connected to the top of the screening box 2. Through the arrangement of the slide rail 23 and the slider 24, the screening box 2 is slidably connected to the top of the inner wall of the shell 1, which can improve the stability and smoothness of the left and right movement of the screening box 2.

[0043] Working principle: When in use, first pull the baffle to the side away from the upper hopper 22 to open the upper hopper 22, and then the staff will put the titanium dioxide to be screened into the screening box 2 in the shell 1 through the upper hopper 22. After the feeding is completed, push the baffle into the upper hopper 22 and close the upper hopper 22 to prevent dust from spreading from the upper hopper 22 to the outside of the shell 1 and polluting the environment during the titanium dioxide screening process;

[0044] After the loading is completed, the driving motor 5 is started, and the output end of the driving motor 5 rotates to drive the main gear 6 to rotate, and then drives the sub-gear 7 meshing with it to rotate, and drives the rotating shaft 8 and the cam 9 to rotate synchronously. During the rotation of the cam 9, when the cam 9 rotates to abut against the screening box 2, it will continue to rotate and push the screening box 2 to move to the side away from the cam 9, and the screening box 2 squeezes the return spring 4 to make it in a compressed state and store energy. When the cam 9 rotates to separate from the screening box 2, the elastic force of the return spring 4 pushes the screening box 2 to reset, so that when the cam 9 continues to operate, the screening box 2 can be driven to vibrate back and forth. The left and right vibrations of the screening box 2 can drive the titanium dioxide contained inside to vibrate, which is conducive to the titanium dioxide of qualified size in the screening box 2 to quickly pass through the screening plate 3, and the screening efficiency of the titanium dioxide can be improved.

[0045] During the rotation of the rotating shaft 1 8, the kinetic energy can be transmitted to the rotating shaft 2 10 through the cooperation of the main pulley 12, the transmission belt 14 and the auxiliary pulley 13, driving the rotating shaft 10 to rotate, and then driving the cleaning rack 11 to rotate. The rotating cleaning rack 11 can move the titanium dioxide accumulated on the top of the screening plate 3 to prevent large-sized titanium dioxide from clogging the screening plate 3, making it easier for titanium dioxide of qualified size to pass through the screening plate 3 smoothly, further improving the screening efficiency of titanium dioxide;

[0046] When the screen plate 3 needs to be cleaned, maintained or replaced, the staff manually pulls up the vertical rod 18 to drive the limit block 19 to move up, and squeezes the extrusion spring 20 to compress it and store energy until the limit block 19 moves up to the top of the screen plate 3, thereby releasing the limit fixation of the screen plate 3. Then, the worker pulls the screen plate 3 toward the outside of the screening box 2, driving the plug plate 16 to withdraw from the slot 15, and completes the disassembly of the screen plate 3. Conversely, the plug plate 16 on the screen plate 3 is completely inserted into the slot 15, and then the vertical rod 18 is released, and the limit block 19 is pushed downward by the elastic force of the extrusion spring 20, so as to limit and fix the screen plate 3 and complete the installation of the screen plate 3. The operation is simple and convenient, which is conducive to the workers to clean, maintain or replace the screen plate 3.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
