Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide production and blanking, and more specifically to a core-encapsulated titanium dioxide production and blanking device. Background Art

[0002] Titanium dioxide is an important inorganic chemical pigment, the main component of which is titanium dioxide. There are two production processes for titanium dioxide: the sulfuric acid process and the chlorination process. It has important uses in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. In the rubber industry, titanium dioxide is used as a colorant and has reinforcing, anti-aging, and filling effects. Titanium dioxide is also increasingly used in cosmetics.

[0003] The patent document with publication number CN210279343U in the prior art provides a ball mill device for titanium dioxide production. The device conveys titanium dioxide to the first grinding chamber through a rotating auger, and then the motor drives the second gear to rotate, thereby driving the first gear to rotate, thereby driving the shell to rotate. The titanium dioxide ground in the first grinding chamber flows into the second grinding chamber through the small holes on the first baffle, and the qualified titanium dioxide in the second grinding chamber will flow into the discharge chamber, so that the treatment of titanium dioxide is more thorough, and the qualified rate of the product is increased.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the steel balls used as grinding bodies are not ground sufficiently, and the product qualification rate does not meet the requirements; secondly, the small steel balls in the device may block the holes on the baffle, making it difficult to unload the material, which needs to be improved. In view of this, we propose a unloading device for the production of core-coated titanium dioxide. Utility Model Content

The utility model drives the fixed shaft 4 to rotate through the first motor 6, thereby driving the movable shaft 3 to rotate, and then driving the grinding roller 7 to rotate. The grinding roller 7 and the circumferential inner wall of the grinding drum 2 squeeze and crush the core-encapsulated titanium dioxide powder. When the fixed shaft 4 rotates, the second bevel gear 506 rotates accordingly, and the second bevel gear 506 drives the first bevel gear 505 meshing with the second bevel gear 506 to rotate, and the half gear 503 is rotated through the connecting rod, and the transmission tooth plate 502 meshing with it is driven to move by the half gear 503, and the transmission tooth plate 502 is reset by the spring 508 to achieve reciprocating up and down movement, so that the bearing 501 drives the movable shaft 3 to move up and down, and then the grinding roller 7 moves up and down, so that the grinding of the core-encapsulated titanium dioxide powder is more sufficient.

[0029] Specifically, the blanking assembly 8 includes a blanking hopper 801 fixed at the bottom of the rolling cylinder 2. On one side inside the blanking hopper 801, a second motor 803 is fixed. At the top opening of the blanking hopper 801, a filter screen 802 is fixed. At the output end of the second motor 803, a vibrating rod 804 is fixed. A plurality of vibrating sleeves 805 are sleeved on the top end of the vibrating rod 804. The second motor 803 is electrically connected to an external power supply. The processed coated titanium dioxide is collected through the blanking hopper 801, and higher-quality coated titanium dioxide is screened out through the filter screen 804 to improve the product qualification rate.

[0030] Further, the bottom surface of the blanking hopper 801 is inclined, and the size of the top opening of the blanking hopper 801 matches the size of the bottom opening of the rolling cylinder 2.

The U-shaped frame 1 can accommodate devices such as the rolling cylinder 2 without occupying space, and the frame 1 is more firmly installed through the screw holes 10.

[0033] In addition, a plurality of stirring rods 11 are annularly and arrayedly distributed on the circumferential outer wall of the moving shaft 3, and the stirring rods 11 are located above the rolling roller 7. Through the plurality of stirring rods 11 annularly and arrayedly distributed on the circumferential outer wall of the moving shaft 3, large pieces of unprocessed coated titanium dioxide raw materials can be broken when the moving shaft 3 rotates, making the grinding of the rolling roller 7 more sufficient.

[0034] In addition, the circuits, electronic components, and modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either;

[0036] The model of the first motor 6 can be: Y90S-2;

[0037] The model of the second motor 803 can be: Y60S-2.

[0038] Working principle: When the device is needed to produce and discharge core-coated titanium dioxide, the staff will place the frame 1 at the required position, use bolts to pass through the screw holes 10 to fix the frame 1, add core-coated titanium dioxide raw materials through the feed port 9, turn on the power, and drive the fixed shaft 4 to rotate through the first motor 6, thereby driving the movable shaft 3 to rotate, and then driving the roller 7 to rotate. The roller 7 and the inner wall of the circumference of the roller 2 squeeze and crush the core-coated titanium dioxide. When the fixed shaft 4 rotates, the second bevel gear 506 rotates accordingly, and the second bevel gear 506 drives the first bevel gear 505 meshing with the second bevel gear 506 to rotate, and the half gear 503 is rotated through the connecting rod, and the transmission tooth plate 502 meshing with the half gear 503 is driven to move by the half gear 503, and the transmission tooth plate 502 is reset by the spring 508 to achieve The reciprocating up and down movement causes the bearing 501 to drive the moving shaft 3 to move up and down, and then the grinding roller 7 to move up and down, so that the core-coated titanium dioxide powder can be ground more fully. The multiple stirring rods 11 distributed in a circular array on the outer wall of the circumference of the moving shaft 3 can break up large pieces of unprocessed core-coated titanium dioxide powder raw materials when the moving shaft 3 rotates, which is convenient for the subsequent grinding of the grinding roller 7. The processed core-coated titanium dioxide powder is collected by the lower hopper 801, and the filter screen 804 selects out higher-quality core-coated titanium dioxide powder to improve the product qualification rate. The second motor 803 drives the vibration rod 804 to rotate, and the vibration sleeve 805 continuously hits the filter screen 802 to vibrate the filter screen 802 to improve the filtering efficiency of the core-coated titanium dioxide powder. The filtered core-coated titanium dioxide powder slides down from the inclined bottom surface of the lower hopper 801, and the power is turned off after the collection is completed.
