Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a multi-stage pulverizing device for producing aluminum phosphide powder. Background Art

[0002] At present, the multi-stage crushing device for the production of aluminum phosphide powder is a device used to produce aluminum phosphide powder. It adopts multi-stage crushing technology to achieve ultrafine crushing of aluminum phosphide. Its main working principle is to use crushing chambers with multiple crushing levels to gradually crush the raw materials into ultrafine aluminum phosphide powder through different levels of crushing methods.

[0003] The authorization announcement number in the prior art is: CN217856403U, and the name is a multi-stage crushing device for raw materials used in the production of alumina powder, including: a first crushing chamber, a second crushing chamber and a third crushing chamber, which are connected in sequence, and two crushing shells are fixedly connected to each crushing chamber to form a continuous crushing process. Two corresponding crushing rollers are arranged in each crushing chamber to finely crush and grind the raw materials according to the particle size and hardness. The patent improves the crushing effect and fineness of alumina through multi-stage crushing, does not require air ducts and fans, simplifies the structure and improves efficiency and speed. This device provides strong support for the production of alumina powder;

[0004] However, when this patent is in use, dust will be raised inside the device and stick to the inner wall of the device. The operator needs to clean and maintain the inner wall of the device after the operation, which makes the cleaning and maintenance of the equipment more cumbersome. When this patent is in use, if the crushing roller is not thoroughly crushed, the incompletely crushed powder will be mixed into the crushed powder, thereby reducing the processing quality of the product.

[0005] The authorization announcement number in the prior art is: CN205462574U, and the name is a crushing and mixing device for aluminum phosphide production, including: an external frame, a feed hopper, a mixing and crushing barrel, a crushing knife, a fixed shaft and a power system. A feed hopper is arranged below the mixing and crushing barrel, which is connected to the fixed shaft through a bearing and can rotate freely. The crushing knife is arranged in the mixing and crushing barrel, which can crush the material and stir the material. The power system drives the mixing and crushing barrel to rotate to achieve mixing and crushing of the material. The patent has a simple structure, easy operation, uniform mixing, and good crushing effect, providing efficient, safe and controllable technical support for aluminum phosphide production.

[0006] However, when this patent is in use, the internal components of the equipment crush and stir the product, causing the crushed dust to fly inside the equipment, resulting in a large amount of dust sticking to the inside of the equipment, requiring operators to clean it frequently, making equipment maintenance more cumbersome.

[0036] Example 2

[0037] like Figure 1 - Figure 4 As shown, this embodiment also introduces a multi-stage crushing device for the production of aluminum phosphide powder, which adds the following structure on the basis of the first embodiment: a partition plate 4 is fixedly connected to the bottom of the first crusher 1, and a filter drawer 5 is slidably installed inside the partition plate 4, and a filter screen 6 is fixedly connected inside the filter drawer 5, and a rotating motor 7 is installed inside the first crusher 1, and the output end of the rotating motor 7 is connected to a coaxially arranged driven reciprocating screw 9 through a coupling, and a sliding block 10 is slidably installed on the outer peripheral surface of the driven reciprocating screw 9, and a cleaning plate 11 is fixedly connected to the bottom of the sliding block 10, and a guide rod 8 is fixedly connected inside the first crusher 1. Through the arrangement of the driven reciprocating screw 9, the cleaning plate 11 and other structures, when the equipment is started, the rotating motor 7 is started, driving the driven reciprocating screw 9 to rotate, driving the sliding block 10 to slide back and forth along the guide rod 8, and driving the cleaning block 111 to reciprocate and clean the filter screen 6, so that the equipment is more convenient to use.

At this time, the rotating motor 7 is started, and the rotating motor 7 drives the driven reciprocating screw 9 to rotate. The driven reciprocating screw 9 drives the sliding block 10 to slide back and forth along the guide rod 8. The sliding block 10 drives the cleaning plate 11 to sweep away the coarse powders on the filter screen 6 to facilitate the rolled products to fall into the second crusher 17. When there are too many coarse powders on the filter screen 6, the operator pulls out the filter drawer 5 inside the partition 4 and cleans the filter screen 6 on the filter drawer 5. After cleaning, the filter drawer 5 is stuffed back into the first crusher 1, so that the equipment can remove the powder that does not meet the rolling standards when it is in use, thereby improving the processing quality of the equipment.

[0041] After the product is crushed by three crushers, the third crusher 18 will drop the crushed powder into the collection drawer 13 in the collection box 12 through the filter screen 6 inside the third crusher 18. After the powder falls on the support plate 16 in the collection drawer 13, it drives the support plate 16 to squeeze the weighing device 15. The weighing device 15 displays the final weight on the digital display 14, so that the operator can accurately understand the weight of the crushed powder in the collection drawer 13, so that the equipment can accurately measure the weight of the finished product.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
