Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer raw material crushing device. Background Technology

[0002] In agricultural production, fertilizer raw materials need to be pulverized before they can be used to prepare fertilizers. Existing pulverizing equipment often suffers from problems such as uneven pulverization and low efficiency, which affects the production efficiency and quality of fertilizers. Therefore, it is essential to design a device that can efficiently and uniformly pulverize fertilizer raw materials.

[0003] However, in the use of traditional mixers, because the internal cavity of the crusher is directly connected to the outside, the high-speed rotating rotor may eject materials through the channel at the feed inlet, damaging the equipment and causing personal injury to the operators; a large amount of dust is generated during the crushing process, which not only affects the production environment, but may also threaten the health of the operators.

[0004] Therefore, we have proposed a fertilizer raw material crushing device. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer raw material crushing device to solve the problem of a large amount of dust generated during the material ejection from the feed inlet and the crushing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fertilizer raw material crushing device, comprising a support, a left support, a right support, and a crushing box. The crushing box is arranged inside the support, and an L-shaped feed inlet is provided on the crushing box. The L-shaped feed inlet includes an inclined feed inlet, which is connected to a vertical discharge outlet. A fixed shaft is provided at the upper end of the connection between the inclined feed inlet and the vertical discharge outlet, and a one-way opening baffle is connected to the fixed shaft. A stop block is provided at the lower end of the connection between the inclined feed inlet and the vertical discharge outlet. The vertical discharge outlet is connected to the crushing box, and a dust removal mechanism is provided on the crushing box.

[0007] Furthermore, the dust removal mechanism includes a dust removal support, a gas-solid separation tank is provided inside the dust removal support, a dust collection box is connected to the lower end of the gas-solid separation tank, an air inlet pipe is provided on the side end of the gas-solid separation tank, an air outlet pipe is provided at the upper end of the gas-solid separation tank, and an induced draft fan is connected to the end of the air outlet pipe.

[0008] Furthermore, a left bracket is fixedly connected to the left end of the bracket, a right bracket is fixedly connected to the right end of the bracket, a first motor is fixedly mounted on the left bracket, and a second motor is fixedly mounted on the right bracket.

[0009] Further, the pulverizing box comprises a pulverizing box body, a discharge port is arranged at the lower end of the pulverizing box body, and an electric butterfly valve is arranged on the discharge port.

[0010] Further, the output end of the first motor is connected with a first rotating shaft penetrating through the side wall of the pulverizing box body, one end of the first rotating shaft away from the first motor is rotationally connected with the side wall of the pulverizing box body, a pulverizing roller is fixedly arranged on the first rotating shaft, and a plurality of pulverizing teeth are arranged on the surface of the pulverizing roller; the output end of the second motor is connected with a second rotating shaft penetrating through the side wall of the pulverizing box body, one end of the second rotating shaft away from the second motor is rotationally connected with the side wall of the pulverizing box body, a pulverizing roller is fixedly arranged on the second rotating shaft, and a plurality of pulverizing teeth are arranged on the surface of the pulverizing roller; the pulverizing rollers are arranged in two parallel groups, and the pulverizing teeth of the two groups of pulverizing rollers are meshed.

[0011] The utility model has the advantages of the following beneficial effects:

[0012] Through cooperation of the L-shaped feeding port and the pulverizing box, the L-shaped feeding port is provided with a one-way opening baffle which opens in the feeding direction, under the premise of not affecting normal feeding, the one-way opening baffle can effectively prevent materials from being shot out through the channel at the feeding port when the pulverizing box is working, thereby protecting equipment and operators, and the design of the L-shaped feeding port can also prevent materials from being shot out during pulverization.

[0013] Through the arrangement of the dust removal mechanism, the induced draft fan introduces dust in the pulverizing box to the gas-solid separation tank through the air inlet pipe, the dust settles and falls into the dust collection box, and the one-way opening baffle of the L-shaped feeding port can also prevent dust in the pulverizing box from overflowing from the feeding port, thereby effectively preventing dust from affecting the production environment and threatening the health of operators.
