Description

Technical Field

[0001] The invention relates to the technical field of rice husk processing, in particular to a pulverizing device for carbonizing rice husk. Background Art

[0002] Carbonized rice husk refers to the charred material formed by heating the rice husk to a temperature below its ignition point so that it is not fully burned. It has the characteristics of light weight and low thermal conductivity. In industrial production, it can be used as a thermal insulation material for the production of steel, iron, etc. In agriculture, it can be used for the cultivation of vegetables, flowers, seedlings, fruit trees and other crops, and to improve the soil. In life, it can be used as a clean energy source for fire and heating. It can also be used as a raw material for the production of steelmaking auxiliary materials. The price in the market varies depending on the C content. To distinguish different qualities of rice husks, you can rub them by hand. If they are broken into granular black solids and will not be kneaded into a ball or sand, such rice husks are of very good quality. If they are ash-like, the quality is very low, and using them in steelmaking will have an adverse effect on the steel.

[0003] The existing crushing device has a single structure. Since the carbonized rice husk is fragile, it is easy to grind the carbonized rice husk into ash by crushing the crushing blade directly, resulting in poor quality of the crushed rice husk. In addition, since the carbonized rice husk is small in size, it can only be crushed in a single stage, which easily produces a crushing dead angle, making the crushing rough and affecting the quality of rice husk processing.

[0004] Therefore, it is necessary to conduct further research on the existing crushing device and provide a new crushing device for carbonizing rice husk. Summary of the invention

[0005] The present invention aims to solve the deficiencies in the prior art and provides a pulverizing device for carbonizing rice husks.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a crushing device for carbonizing rice husks, comprising a crushing box, a frame, a control switch, a feed hopper, a first rotating motor, a first rotating shaft, a guide block, a crushing block, a fixed frame, a second rotating motor, a second rotating shaft, a crushing barrel, a discharge port and a discharge hopper, wherein the outer end of the crushing box is fixedly connected to the frame by bolts, a control switch is installed at the upper left end of the frame, a feed hopper is arranged on the left side of the top of the crushing box, a first rotating motor is arranged at the middle of the top of the crushing box, a first rotating shaft is arranged at the lower end of the first rotating motor, a guide block is fixedly connected to the lower end of the first rotating shaft, a crushing block is fixedly connected to the lower end of the guide block, a fixed frame is fixedly connected to the middle of the bottom of the crushing box by bolts, a second rotating motor is placed inside the fixed frame, a second rotating shaft is arranged at the upper end of the second rotating motor, a crushing barrel is arranged inside the crushing box, discharge ports are arranged on the left and right sides of the lower end of the crushing barrel, and discharge hoppers are arranged on the left and right sides of the bottom of the crushing box.

[0007] Preferably, the control switch, the first rotating motor and the second rotating motor are all connected to an external power source through wires, and the control switch is electrically connected to the first rotating motor and the second rotating motor through wires.

[0008] Preferably, the first rotating shaft passes through the pulverizing box and extends vertically downward to the inside of the pulverizing cylinder, and the guide block and the pulverizing block are both located inside the pulverizing cylinder.

[0009] Preferably, the guide block is in a truncated cone shape, and the diameter of the guide block is smaller than the diameter of the crushing block.

[0010] Preferably, the crushing block is disc-shaped, and a plurality of groups of trapezoidal protrusions are evenly arranged on the outer end of the crushing block.

[0011] Preferably, the second rotating shaft vertically extends upward to the interior of the pulverizing cylinder, and the second rotating shaft is fixedly connected to the pulverizing cylinder.

[0012] Preferably, a plurality of groups of sawtooth-shaped protrusions are evenly arranged on the inner wall surface of the pulverizing cylinder, and there is a 2 mm interval between the pulverizing cylinder and the pulverizing blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The pulverizing device for carbonized rice husk, when the carbonized rice husk falls onto the guide block, since the guide block is in the shape of a truncated cone, the rotating truncated cone guide block evenly disperses the carbonized rice husk downward into the gap between the pulverizing block and the pulverizing barrel. The outer end of the pulverizing block is evenly provided with a plurality of groups of trapezoidal protrusions, which can increase the contact area with the carbonized rice husk. The second rotating motor drives the pulverizing barrel to rotate via the second rotating shaft. The inner wall surface of the pulverizing barrel is evenly provided with a plurality of groups of sawtooth-shaped protrusions. The pulverizing block and the pulverizing barrel rotate simultaneously. There is a 2 mm interval between the pulverizing barrel and the pulverizing block. The carbonized rice husk can be cut off by the trapezoidal protrusions at the outer end of the pulverizing block and the sawtooth-shaped protrusions evenly provided on the inner wall surface of the pulverizing barrel, and directly falls downward into the pulverizing box through the discharge port. Compared with the traditional pulverizing device, the carbonized rice husk can be crushed into particles, and can be avoided from being crushed into ash, thereby ensuring the pulverizing quality of the rice husk.

[0015] (2) The crushing device for carbonized rice husks can spread out the rice husks between the crushing barrel and the crushing blocks and crush them by continuously rotating the crushing barrel. The sawtooth-shaped protrusions evenly arranged on the inner wall surface of the crushing barrel can effectively eliminate the crushing dead corners and crush most of the carbonized rice husks, making the crushing more refined and effectively ensuring the crushing quality of the rice husks.
