Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide production technology, and in particular to a feeding device for the production of antistatic coated titanium dioxide. Background Technology

[0002] Antistatic coated titanium dioxide typically uses titanium dioxide as a base, and through a special production process, a conductive or antistatic coating layer is formed on its surface, thus producing antistatic titanium dioxide. This surface coating treatment imparts a certain degree of conductivity, effectively dissipating static electricity from object surfaces, preventing static buildup, and reducing the harmful effects of static electricity, such as electrostatic adsorption and electrostatic discharge. Even after coating, it retains good optical properties and can be made into near-white and other light-colored products, meeting the needs of applications with high color accuracy requirements.

[0003] The existing application publication number CN219216873U discloses a feeding device for a rotary kiln for calcining titanium dioxide, including a frame, a conveying device, a receiving hopper, and grinding rollers. The receiving hopper is set on the frame and located below the discharge end of the conveying device. There are at least two grinding rollers, both of which are rotatably mounted on the inner wall of the receiving hopper. Adjacent grinding rollers rotate in opposite directions and form a grinding chamber between their opposite sidewalls. The receiving hopper is equipped with a driving device for driving the grinding rollers to rotate. A uniform discharge component is set in the receiving hopper below the grinding rollers. This application can reduce the amount of large pieces of material added to the rotary kiln, making the material added to the rotary kiln uniformly and improving the calcination effect of the material.

[0004] However, this solution still has shortcomings. Gaps exist inside the casing, preventing some titanium dioxide raw materials from being effectively processed during crushing, thus affecting overall crushing efficiency. Furthermore, the equipment lacks a preliminary processing step for large pieces of material, hindering subsequent crushing and refining processes. Therefore, it is necessary to provide an antistatic encapsulated titanium dioxide production feeding device to solve the above technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for the production of antistatic coated titanium dioxide.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for the production of antistatic coated titanium dioxide, comprising a conveyor belt, a feeding box on the right side of the conveyor belt, a feed hopper connected to the top of the feeding box, and a discharge hopper connected to the bottom of the feeding box. Inside the feeding box, a first crushing roller, a second crushing roller, and a grinding roller are rotatably arranged sequentially from top to bottom. A frame is connected to the outer wall of the feeding box; the first crushing roller is located on the side closest to the feed hopper, and there are two of each of the second crushing roller and the grinding roller. Each layer of rollers is placed side by side. The front and rear sides of the feeding box are equipped with power components, which are used to drive the rotation of each layer of rollers. A first stop is provided on the right side of the first crushing roller. The cross-section of the first stop is shaped like a mound, and the bottom of the first stop is connected to the inner wall of the feeding box. A second stop is provided between each of the two grinding rollers and the inner wall of the feeding box. The upper and lower sides of the second stop are inclined surfaces that slope towards the center. The side of the second stop closer to the grinding roller is concave and arc-shaped, and the side of the second stop away from the grinding roller is connected to the inner wall of the feeding box.

[0007] Preferably, each of the two grinding rollers is provided with a plurality of annular grinding blocks, the outer surface of the plurality of annular grinding blocks is a smooth structure, the plurality of annular grinding blocks are arranged at equal intervals along the axial direction of the grinding roller, and the plane in which the plurality of annular grinding blocks are located is perpendicular to the axial direction of the grinding roller.

[0008] Preferably, the outer surface of the first crushing roller is a raised spiky structure, and the outer surfaces of the two second crushing rollers are raised rod-shaped structures.

[0009] Preferably, the power assembly includes a first motor and a second motor connected to the front side of the feeding box, the output end of the first motor extends into the feeding box and is connected to the first crushing roller, and the output end of the second motor extends into the feeding box and is connected to the grinding roller at the left end.

[0010] Preferably, the rear sides of the two grinding rollers extend into feeding boxes and are respectively connected to the grinding roller drive teeth, and the two grinding roller drive teeth mesh with each other. The rear side of the first crushing roller extends into a feeding box and is sequentially connected to the first crushing roller drive teeth and the first crushing roller drive wheel. The rear sides of the left and right second crushing rollers extend into feeding boxes and are respectively connected to the second crushing roller drive teeth and the second crushing roller drive wheel. The first crushing roller drive teeth and the second crushing roller drive teeth mesh with each other. The first crushing roller drive wheel and the second crushing roller drive wheel are connected by a belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, during the crushing process, the first stop effectively resists titanium dioxide, preventing some raw materials from remaining uncrushed due to gaps inside the feeding box, thus significantly improving crushing efficiency. The second stop has multiple functions: its top sloping surface guides the flow of titanium dioxide, increasing the contact area with the grinding rollers; the side near the grinding rollers is concave and rounded, adapting to the dual grinding rollers, reducing the gap inside the feeding box and preventing raw material leakage; the bottom sloping surface is used to clean the surface of the titanium dioxide, preventing material adhesion.

[0013] After titanium dioxide enters the feeding box through the feed hopper, the first crushing roller breaks up any agglomerated material, laying the foundation for subsequent processing. The initially crushed agglomerated material then undergoes secondary crushing by two second crushing rollers, further refining the material. Subsequently, the material is compressed by two grinding rollers to achieve deep refinement, ensuring the product meets quality standards. The equipment is powered by an electric motor, ensuring stable and efficient operation throughout the entire processing. Attached Figure Description

[0025] The first baffle 6 can block the titanium dioxide during the crushing process, preventing some raw materials from being uncrushed due to gaps inside the feed box 2, thus further improving crushing efficiency; the upper inclined surface of the second baffle 7 is used to guide the titanium dioxide and increase the contact with the grinding roller 5.
