Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a high-efficiency pulverizing device for aluminum phosphide raw materials. Background Art

[0002] At present, aluminum phosphide technical is a chemical substance, which is mainly used for fumigation and pest control, such as fumigation of raw grains, finished grains, seed grains and various storage equipment. At the same time, it can also be used for pest control in other closed places, killing rats in rat holes and killing longhorn beetles on tree trunks. The chemical properties of aluminum phosphide technical are light yellow or gray-green square crystalline powder, odorless, slightly soluble in cold water, soluble in ethanol and ether.

[0003] The prior art has an authorized announcement number of CN219942983U, which discloses an aluminum phosphide raw material crushing device, including a studio, a feed port, a baffle, a fan, a ventilation pipe, a crushing roller, a telescopic end of an electric push rod, a screening plate, a collection box, a receiving port, a return chamber and a filter cartridge. The material enters the studio through the feed port, and after being crushed by the crushing roller, the screening plate collects the qualified material into the collection box, and the incompletely crushed material returns to the return chamber for secondary processing. At the same time, the fan drives the air flow through the ventilation pipe, collects the dust in the studio and filters it through the filter cartridge to prevent the dust concentration from being too high. The patent improves the processing efficiency and facilitates people's use;

[0004] However, the patent realizes the input of materials through the feed port, and a large amount of materials accumulate inside the feed port, which makes it difficult to achieve better crushing. In addition, the vibration of the screening plate is realized by the reciprocating motion of a separate electric push rod. The installation and use cost of the separate electric push rod is high, which makes the crushing efficiency of the device low.

[0005] The prior art has an authorization announcement number of CN212167277U, which discloses a circulating pulverizing device for aluminum phosphide production. The device includes a box, a feed port, a pulverizing roller, a stirring tank, a discharge port, a stirring assembly, a screen, a screw conveyor, and a vibration motor. The material enters through the feed port, and after the initial pulverization by the pulverizing roller, it falls into the screen for screening. The material that meets the standard continues to fall, and the material that does not meet the standard is returned to the feed port by the fan and the screw conveyor for re-pulverization. The vibration motor improves the screening efficiency, and the motor and the stirring rod mix the pulverized raw materials. The patent has a compact structure, is easy to operate, and improves the efficiency of aluminum phosphide production.

[0006] However, in this patent, a large amount of material is accumulated at the crushing roller, and the accumulation of material makes it difficult for the crushing roller to work better, affecting the crushing efficiency. Utility Model Content

[0039] Example 2

[0040] like Figure 1-Figure 5As shown, this embodiment also introduces a high-efficiency crushing device for aluminum phosphide raw materials, which adds the following structure on the basis of Example 1: two box doors 11 are installed on one side of the crushing box 2, and a handle 12 is fixedly connected to one side of the box door 11.

[0041] The specific implementation principle of this embodiment is as follows: a sealing strip is provided on the box door 11 to ensure the sealing of the connection of the box door 11. Pulling the handle 12 drives the box door 11 to open, making it more convenient for the staff to maintain the internal components of the crushing box 2, and also convenient for the treatment of residual materials on the filter plate 6. The crushed raw medicine falls into the collection vehicle 7. The position of the collection vehicle 7 is limited by the block 10 to prevent the collection vehicle 7 from blocking the movement of the cross bar 501 and the connecting rod 500. Pulling the handrail 8 makes it more convenient for the staff to push the collection vehicle 7, and the wheels 9 make the movement of the collection vehicle 7 more convenient.
