Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a silicon ore grinding device. Background Art

[0002] Silicon ore refers to the ore entity of silicon that can be mined, rather than the silicon compounds that are widely present in nature. The content of elemental silicon in the earth's crust is about 25.7% of the total weight of the earth's crust, making it the most abundant element after oxygen. Silicon and oxygen have a strong affinity, so there is no free silicon in nature. Silicon must exist in the form of its oxides and silicates. Silicon oxides mainly include sand, quartz, crystal, purple quartz, agate, flint and opal. Silicates mainly include granite, amphibole, asbestos, feldspar, clay and mica, etc. The mining of these silicon compounds constitutes silicon ore. Silicon ore is generally in large blocks when mined, and needs to be crushed and ground into powder before subsequent processing.

[0003] The Chinese utility model patent "A mineral grinding device" with publication number CN218654684U discloses the following content: it includes: a fixed support plate, a grinding mechanism and a driving mechanism; the grinding mechanism is arranged above the fixed support plate, the grinding mechanism includes a grinding support tube, a plurality of evenly distributed first grinding protrusions are installed on the inner wall of the grinding support tube, a rotating column is inserted in the grinding support tube, and a plurality of evenly distributed second grinding protrusions are installed on the outer wall of the rotating column; the driving mechanism is arranged above the grinding support tube, the driving mechanism includes a motor, a transmission support shaft is connected to the motor, the other end of the transmission support shaft is connected to a support boss, and the support boss is fixed on the rotating column.

[0004] The grinding device in the above patent is inconvenient to feed materials during grinding, and the materials cannot be evenly fed between the wide-mouth tube and the supporting boss. In the subsequent grinding process, some of the first grinding protrusions and the second grinding protrusions cannot be fully used, resulting in a decrease in grinding efficiency. In addition, during the grinding process, only the rotating column is rotating for grinding, resulting in low grinding efficiency.

[0005] Therefore, there is an urgent need for a silicon ore grinding device to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the existing technical problems and provide a silicon ore grinding device.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:

[0008] A silicon ore grinding device comprises a grinding box and a motor A. A grinding sleeve and a grinding block arranged in the grinding sleeve are arranged in the grinding box; the motor A drives the grinding block to rotate in the grinding sleeve; and further comprises a material distribution component arranged above the grinding sleeve;

[0009] The upper end surface of the grinding box is provided with a feeding screw; the feeding pipe of the feeding screw extends into the grinding box;

[0012] The lower block extends into the grinding chamber; a rotating shaft is fixed through the center of the grinding block, and the head of the rotating shaft passes through the upper end surface of the grinding box and is connected to the motor A;

[0013] The material distribution assembly comprises an annular material distribution groove with an open upper end surface; the bottom surface of the material distribution groove is evenly distributed with material distribution holes; the outside of the material distribution groove is fixedly connected to the inner wall of the grinding box through a plurality of support rods;

[0014] The material distribution trough is coaxial with the rotating shaft, and a material distribution plate is connected to the rotating shaft above the material distribution trough through a connecting rod; the material distribution plate extends into the material distribution trough, and the lower end surface of the material distribution plate contacts the bottom of the material distribution trough; the vertical downward projection of the material discharge pipe falls into the material distribution trough;

[0015] The lower end surface of the grinding sleeve is provided with a lower hopper, and the lower end of the lower hopper passes through the grinding box and extends to the outside of the grinding box.

[0016] When the utility model is in use, the silicon ore to be ground (hereinafter referred to as material) enters the grinding box through the feeding screw, the material is guided into the feeding trough by the feeding pipe, and the rotating shaft rotates to drive the feeding plate and the grinding block to rotate. During the rotation process, the feeding plate evenly scrapes the material in the feeding trough, so that it evenly falls between the grinding block and the grinding sleeve through the feeding hole, and then enters the gap between the grinding block and the grinding sleeve under the action of gravity for grinding, and the ground material is discharged from the lower hopper.

[0017] Preferably, grinding protrusions are provided on the outer side surface of the lower block and the inner side surface of the grinding sleeve.

[0018] The gap between the lower block and the grinding sleeve decreases from top to bottom. The specific gap setting is set according to the actual grinding requirements, and the size and dimensions of the grinding protrusion can also be set according to the actual usage requirements, which will not be described in detail here.

[0019] Preferably, the ring width of the upper end surface of the material distribution trough is greater than the ring width of the lower end surface thereof.

[0020] This arrangement makes the inner annular surface of the material distributing trough tilt outward and the outer annular surface tilt inward, which can better guide the material and also facilitate the rotation of the material distributing plate.

[0021] Preferably, an annular mounting groove is provided on the outer side wall of the grinding sleeve, and a bearing A is installed in the mounting groove; the grinding sleeve is rotatably connected to the grinding box through the bearing A;

[0023] This arrangement allows the grinding sleeve and the grinding block to be driven to rotate during the grinding process, and the rotation directions of the grinding sleeve and the grinding block are opposite. This rotation method further speeds up the grinding speed and improves the grinding efficiency. The active main gear and the driven bevel gear used in the utility model are both based on existing technologies. Those skilled in the art can select specific models according to actual usage requirements, which will not be described in detail here. The inner diameter of the passive bevel gear used in the utility model needs to be larger than the outer diameter of the discharge hopper, so that the grinding sleeve can be rotated without affecting the discharge of materials.

[0024] The outer diameter of the grinding sleeve matches the inner diameter of the grinding box, and the gap between them should be as small as possible while ensuring smooth rotation of the grinding sleeve.

[0025] Preferably, the upper end surface of the lower hopper is provided with a bearing B, and the lower hopper is rotatably connected to the lower end surface of the grinding block via the bearing B.

[0026] This arrangement not only allows the grinding sleeve to rotate smoothly when the lower hopper is stationary, ensuring that the material can be discharged smoothly from the lower hopper; it can also prevent the material from overflowing out of the lower hopper during the discharge process, affecting the smooth rotation of the active bevel gear and the passive bevel gear.

[0027] Components not defined in the utility model all adopt conventional means in the field. Technicians in the field can select their models and installation methods according to actual usage requirements and clearly understand how to install and control them. They will not be described in detail here.

[0028] The utility model achieves the following beneficial effects:

[0029] The utility model has a simple structure and is easy to operate; the utility model is provided with a cloth component, so that the material can be evenly dropped into the grinding chamber for grinding, thereby improving the grinding efficiency; the grinding block and the grinding sleeve can both rotate, thereby further improving the grinding efficiency.
