Description

Technical Field

[0001] The utility model belongs to the field of crushers and relates to a silica gel crusher. Background Art

[0002] As a high-performance material widely used in multiple fields such as medical treatment, food, electronics, and chemical industry, the processing technology of silica gel has always been one of the research hotspots. In the production and recycling process of silica gel, crushing is a key process, which directly affects the performance and quality of the final product. The purpose of silica gel crushing is to convert large or waste silica gel into fine particles or powders for subsequent processing or recycling.

[0003] The existing silica gel crushers mainly adopt the mechanical crushing principle, and cut, extrude, and rub the silica gel through high-speed rotating blades or grinding disks to achieve crushing. However, due to the high elasticity and flexibility of silica gel, some technical problems often occur in actual operation. This characteristic of silica gel causes it to deform rather than break under the action of external forces, which not only affects the crushing efficiency but also results in low-quality silica gel crushing. Therefore, in order to meet the required fineness requirements, it often takes a long time and higher energy consumption, which undoubtedly increases the production cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a silica gel crusher, which can quickly crush silica gel into fine particles through a multi-stage shearing and crushing method, with high crushing efficiency and good crushing quality.

[0005] To solve the above technical problems, the utility model provides a silica gel crusher, which includes a support. The upper end of the support is provided with a crushing barrel. The upper end of the crushing barrel is communicated with a feeding hopper. A vertically arranged crushing roller is rotatably connected in the crushing barrel. A driving motor for driving the crushing roller to rotate is installed at the upper end of the crushing barrel. A plurality of annular filter screens slidingly connected to the inner wall of the crushing roller are arranged in the crushing barrel from top to bottom. The aperture of the annular filter screen gradually becomes smaller from top to bottom. The crushing barrel and the crushing roller are divided into a plurality of annular crushing chambers distributed from top to bottom through the annular filter screen. The crushing barrel is frustum-shaped, and the crushing roller is inverted frustum-shaped, so that the width of the annular crushing chamber gradually becomes smaller from top to bottom. A plurality of outer crushing cutters distributed in a circumferential manner are arranged on the inner wall of the crushing barrel in each annular crushing chamber. A plurality of inner crushing cutters distributed in a circumferential manner are arranged on the outer wall of the crushing roller in each annular crushing chamber.

[0006] By adopting the above technical solution, when pulverizing silica gel, the silica gel is added from the feeding hopper into the pulverizing barrel, and the driving motor drives the pulverizing roller to rotate at a high speed, so that the inner pulverizing cutter and the outer pulverizing cutter cut the silica gel into pieces. When the size can pass through the annular filter screen, it falls into the next-stage annular pulverizing cavity for pulverization. As the silica gel gradually falls, the pulverizing distance gradually becomes smaller, so that fine silica gel particles can also be fully sheared and pulverized by the inner pulverizing cutter and the outer pulverizing cutter until the pulverization requirement is met, and finally passes through the lowermost annular filter screen.

[0007] The utility model is further arranged such that an annular aggregate trough matched with the lowermost annular filter screen is arranged at the bottom of the pulverizing barrel, and a discharge channel is communicated outward on one side of the annular aggregate trough.

[0008] The utility model is further arranged such that the bottom of the annular aggregate trough is inclined towards the discharge channel.

[0009] The utility model is further arranged such that the cutting edges of each outer pulverizing cutter and the corresponding inner pulverizing cutter are close to each other but cannot touch.

[0010] The utility model is further arranged such that each outer pulverizing cutter is inclined in the same direction in a circumferential manner, and each inner pulverizing cutter is inclined in a direction opposite to that of the outer pulverizing cutter.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] First, the utility model adopts a multi-stage shearing and pulverizing method to gradually shear and pulverize the silica gel into fine particles, which can effectively solve the problem that silica gel is not easy to pulverize due to its high elasticity and high toughness. And the multi-stage pulverization is carried out simultaneously, which can quickly pulverize the silica gel into fine particles stage by stage, with high pulverization efficiency. Moreover, because the fine particles are formed by shearing, the particle quality is better.

[0013] Second, the pulverizer of the utility model has a simple structure, and its main structures are only the pulverizing barrel, the pulverizing roller and the motor, so that the manufacturing cost of the pulverizer is lower and it is easier to promote and use. Description of the Drawings

According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0020] Example, referring to Figures 1-4 , a silicone crusher, including a support 1, a crushing barrel 2 is arranged at the upper end of the support 1, a feeding hopper 3 is communicated with the upper end of the crushing barrel 2, a vertically arranged crushing roller 4 is rotatably connected in the crushing barrel 2, a driving motor 5 for driving the crushing roller 4 to rotate is installed at the upper end of the crushing barrel 2, three layers of annular filter screens 6 slidably connected to the inner wall of the crushing roller 4 are arranged in the crushing barrel 2 from top to bottom, the aperture of the annular filter screen 6 gradually becomes smaller from top to bottom, the crushing barrel 2 and the crushing roller 4 are divided into three annular crushing chambers 7 distributed from top to bottom through the annular filter screen 6, the crushing barrel 2 is frustum-shaped, and the crushing roller 4 is inverted frustum-shaped, so that the width of the annular crushing chamber 7 gradually becomes smaller from top to bottom, so that after the silicone gradually falls, the crushing distance gradually becomes smaller, which is more conducive to crushing the gradually smaller silicone particles.

[0021] A plurality of outer crushing cutters 8 distributed in a circumferential manner are arranged on the inner wall of the crushing barrel 2 in each annular crushing chamber 7, a plurality of inner crushing cutters 9 distributed in a circumferential manner are arranged on the outer wall of the crushing roller 4 in each annular crushing chamber 7, the cutting edges of each outer crushing cutter 8 and the corresponding inner crushing cutter 9 are close to each other but cannot touch, each outer crushing cutter 8 is inclined in the same direction in a circumferential manner, and each inner crushing cutter 9 is inclined in the opposite direction to the outer crushing cutter 8, so that when the inner crushing cutter 9 rotates with the crushing roller 4, it can cooperate with the outer crushing cutter 8 to shear and crush the silicone particles. A circle of annular aggregate trough 10 matching with the lowermost annular filter screen 6 is arranged at the bottom of the crushing barrel 2, one side of the annular aggregate trough 10 is communicated with an outer discharge channel 11, and the bottom of the annular aggregate trough 10 is inclined towards the discharge channel 11, facilitating the rapid discharge of the silicone crushed material from the discharge channel 11.

[0022] Working principle: When pulverizing silica gel, the silica gel is added into the pulverizing barrel 2 from the feeding hopper 3. The driving motor 5 drives the pulverizing roller 4 to rotate at a high speed, so that the inner pulverizing cutter 9 and the outer pulverizing cutter 8 cut the silica gel into pieces. When the size can pass through the annular filter screen 6, it falls into the next-stage annular pulverizing cavity 7 for pulverization. As the silica gel gradually falls, the pulverizing spacing gradually becomes smaller, so that fine silica gel particles can also be fully sheared and pulverized by the inner pulverizing cutter 9 and the outer pulverizing cutter 8 until the pulverization requirement is met. Finally, it passes through the annular filter screen 6 at the bottom and falls into the annular aggregate trough 10 and is discharged from the discharge channel 11.
