[0022] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-3As shown in the figure, this utility model provides a chemical raw material pulverizing and drying device, including a box body 1. A feeding hopper 2 is provided at the top of the box body 1, and the lower end of the feeding hopper 2 extends into the box body 1. A vacuum pump 3 is provided at the top of the box body 1 next to the feeding hopper 2, and the lower end of the vacuum pump 3 extends into the box body 1. A first pulverizing chamber 11, a second pulverizing chamber 12, and a drying chamber 13 are arranged sequentially from top to bottom inside the box body 1. A coarse pulverizing device is provided in the first pulverizing chamber 11, a fine pulverizing device is provided in the second pulverizing chamber 12, and a conveying device is provided in the drying chamber 13. A first connecting port 5 is provided between the first pulverizing chamber 11 and the second pulverizing chamber 12, and a second connecting port 63 is provided between the second pulverizing chamber 12 and the drying chamber 13. A first heater 51 is provided on the inner side wall of the first connecting port 5, and a second heater 73 is provided at the bottom of the drying chamber 13.

[0024] To ensure a dry environment inside chamber 1 and shorten the drying time for subsequent materials, a vacuum pump, a first heater 51, and a second heater 73 are used to vacuum-dry chamber 1, providing a dry environment for the materials. A first grinding chamber 11 and a second grinding chamber 12 are provided for preliminary and further grinding of the materials. After preliminary grinding by the coarse grinding device in the first grinding chamber 11, the materials enter the second grinding chamber 12 through the first connection port 5. The bottom plate of the first grinding chamber 11 is inclined towards the first connection port 5 to facilitate material entry and prevent material from being pushed onto the bottom plate of the first grinding chamber 11. As the material passes through the first connection port 5, the first heater 51 on the inner wall of the first connection port 5 dries the surface of the material, which is beneficial for the subsequent drying process. The fine crushing device in the second crushing chamber 12 further crushes the material. After thorough crushing, the material falls through the second connection port 63 onto the conveying device in the drying chamber 13. The bottom plate of the second crushing chamber 12 is inclined towards the second connection port 63 to facilitate the material's entry into the second connection port 63 and prevent the material from being pushed against the bottom plate of the second crushing chamber 12. The conveying device transports the material left and right, and the second heater 73 thoroughly dries the material during the left and right transport process. Through the above-mentioned device setup, the material is initially crushed by the coarse crushing device, and the surface of the material is dried after initial crushing. Then, the material is further crushed by the fine crushing device. After thorough crushing, the material enters the drying chamber 13 for drying, ensuring that the crushed and dried material meets production requirements and improving work efficiency.

[0025] A cover 21 is provided above the feed hopper 2. One end of the cover 21 is hinged to the feed hopper 2. During the feeding process, the cover 21 is opened to allow the material to enter the first crushing chamber 11 inside the matching box 1 through the feed hopper 2. After the feeding is completed, the cover 21 is closed to keep the box 1 in a sealed state.

[0026] The coarse crushing device includes a rotating shaft 4, which is laterally rotatable inside the first crushing chamber 11. Multiple sets of crushing blades 42 are provided on the outer wall of the rotating shaft 4. A first motor 42 is provided on the outer wall of the housing 1. One end of the rotating shaft 4 extends out of the first crushing chamber 11 and is connected to the output end of the first motor 42.

[0027] During the initial crushing of materials, the motor 42 is started, and the motor 42 drives the rotating shaft 4 to rotate, which in turn drives the crushing blade 42 to act on the materials to perform initial crushing.

[0028] The fine pulverizing device includes two sets of pulverizing shafts 6, which are rotatably arranged in the second pulverizing chamber 12 perpendicular to the rotating shaft 4. Pulverizing saw teeth 61 are provided on the outer wall of the pulverizing shaft 6. Two sets of second motors 62 are provided on the outer wall of the back of the housing 1. One end of the pulverizing shaft 6 extends out of the second pulverizing chamber 12 and is connected to the output end of the second motor 62.

[0029] During the process of the initially crushed material entering the second crushing chamber 12, two sets of second motors 62 are started, causing the two sets of crushing shafts 6 to rotate in opposite directions, thereby causing the two sets of crushing saw teeth 61 to rotate inward, further crushing the material.

[0030] The conveying device includes a spiral blade 7 and a stirring shaft 71. The stirring shaft 71 is installed in the drying chamber 13. The spiral blade 7 is distributed along the axial direction of the stirring shaft 71. A servo motor 72 is installed on the outer wall of the housing 1. One end of the stirring shaft 71 extends out of the drying chamber 13 and is connected to the output end of the servo motor 72.

[0031] The material, after being fully crushed, falls onto the spiral blades 7. The servo motor 72 is started, and under the action of the stirring shaft 71 and the spiral blades 7, the material tumbles left and right in the drying chamber 13. Combined with the second heater 73 at the bottom, the material is fully dried.

[0032] The outer wall of the housing 1 away from the servo motor 72 is provided with a discharge pipe 8, and a baffle 81 is provided on the discharge pipe 8.

[0033] When it is necessary to discharge the dried material outside the box 1, the baffle 81 is pulled away from the discharge pipe 8, and the material is discharged outside the box 1 through the discharge pipe 8. After discharge, the baffle 81 is inserted back into the discharge pipe 8.

[0034] The working principle of this embodiment is as follows: To ensure a dry environment inside the chamber 1 and shorten the drying time of subsequent materials, a vacuum pump, a first heater 51, and a second heater 73 are used to vacuum-dry the chamber 1, providing a dry environment for the materials. A first crushing chamber 11 and a second crushing chamber 12 are set up to perform preliminary crushing and further crushing of the materials. After being initially crushed by the coarse crushing device in the first crushing chamber 11, the materials enter the second crushing chamber 12 through the first connecting port 5. When the materials pass through the first connecting port 5, the first heater 51 on the inner wall of the first connecting port 5 dries the surface of the materials, which is beneficial for the fine crushing device in the second crushing chamber 12 to further crush the materials. The fully crushed materials fall onto the conveying device in the drying chamber 13 through the second connecting port 63. The conveying device transports the materials left and right, and the second heater 73 thoroughly dries the materials during the left and right transport process. Through the above-mentioned device setup, the coarse crushing device performs preliminary crushing of the materials, the surface of the materials is dried after preliminary crushing, and then the materials are further crushed by the fine crushing device. After being fully crushed, the materials enter the drying chamber 13 for drying, ensuring that the crushed and dried materials meet the production requirements and improving work efficiency.
