[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] Example: Please refer to Figure 1-2A solid chemical raw material crushing device includes a casing 1, a feeding port 11 is provided at the upper end of the casing 1, and a pre-crushing mechanism, a grinding mechanism, a screening mechanism and a recycling structure are provided inside the casing 1. The pre-crushing mechanism includes a fixed plate 2, a pre-crushing roller 21 and a brush 212. The fixed plate 2 and the pre-crushing roller 21 are located below the feeding port 11. The pre-crushing mechanism performs pre-crushing treatment on the raw materials entering from the feeding port 11, specifically, the raw materials on the fixed plate 2 are pre-crushed by the pre-crushing roller 21. A certain distance is left between the pre-crushing roller 21 and the fixed plate 2. Solid chemical raw materials greater than the distance will be crushed by the pre-crushing roller 21, so that the raw materials entering the subsequent structure are all less than the distance, which is convenient for improving the subsequent crushing efficiency. The fixed plate 2 is tilted so that the raw material tends to slide down on the fixed plate 2. The surface of the pre-crushing roller 21 is provided with many protrusions 211, which improve the crushing effect of the pre-crushing roller 21 and make it easier for the pre-crushing roller 21 to exert force and squeeze and crush the raw material. The fixed plate 2 is provided with a plurality of blades 22 below the pre-crushing roller 21. When the raw material is squeezed and crushed by the pre-crushing roller 21 between the pre-crushing roller 21 and the fixed plate 2, it is also divided by the blades 22, which further prevents the raw material from agglomerating and reduces its volume. The brush 212 is located on one side of the pre-crushing roller 21, and the brush 212 contacts the surface of the pre-crushing roller 21. The brush 212 can clean the raw material adhering to the surface of the pre-crushing roller 21, thereby improving the pre-crushing efficiency. The grinding mechanism is located below the end of the fixed plate 2. The grinding mechanism includes a protective shell 3 and a grinding roller 31. Two grinding rollers 31 are provided, each driven by a motor. The protective shell 3 is provided with an upper opening and a discharge port. The discharge port is smaller than the upper opening, so that the raw materials ground by the grinding roller 31 are concentrated and leave from the discharge port, and the scattered raw materials are restrained so that they fall into the subsequent screen 4. The screening mechanism is located below the discharge port of the grinding mechanism. The screening mechanism includes a screen 4, a spring 41, a vibration roller 42 and a collection box 43. The screen 4 is arranged at an angle, and at least two springs 41 are provided. The upper and lower ends of the screen 4 are connected to the casing 1 through springs 41 respectively. A vibration roller 42 is provided on the upper side of the screen 4, and a contact rod is provided on the surface of the vibration roller 42. The rotating shaft of the vibration roller 42 is fixedly connected to the output end of the motor. The motor drives the vibration roller 42 to rotate, so that the contact rod periodically touches the screen 4 to realize the vibration of the screen 4, so that the raw materials are screened in the screen 4. The collection box 43 is located below the screen 4, and the raw materials that can pass through the screen 4 fall into the collection box 43. The casing 1 is provided with a slot for the collection box 43 to enter and exit and cooperate with the collection box 43, so that the collection box 43 is detachable, and a handle 431 is provided on the collection box 43 to facilitate holding the collection box 43. The recycling structure includes a recycling port 5 and a recycling container 51. The recycling port 5 is located inside the casing 1 and below the screen 4. The raw materials that fail to pass through the screen 4 enter the recycling port 5 for recycling. The recycling container 51 is located below the recycling port 5 and is used to accommodate the recycled raw materials.

[0024] Working principle of this embodiment: This embodiment provides a solid chemical raw material crushing device. After the raw material enters the housing 1 from the feeding port 11, it is pre-crushed by the fixed plate 2 and the pre-crushing roller 21 in sequence, ground by the grinding mechanism, and screened by the screening mechanism. The bulk raw material is pre-crushed to a suitable size, which facilitates the subsequent structure to crush and improves the crushing efficiency of the solid chemical raw material. The solid chemical raw material crushing device includes two crushing processes, namely, pre-crushing and grinding, which improves the raw material crushing effect and crushing efficiency, and is conducive to the use of chemical production.
