With a high-performance cooling system and an automatic control system, continuous processing and discharging of materials can be achieved, greatly improving production efficiency. However, the sand mill usually uses wet grinding, resulting in the need for drying treatment of the ground raw materials.

[0003] In a chemical raw material grinding device with a preheating and dehumidifying function proposed in the utility model patent CN218742335U of China, preheating is carried out in the feeding channel, so that the initial temperature of the grinding device increases.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-4 , a chemical raw material grinding device with a preheating and dehumidifying function, including a grinding device body 1. A discharge channel 2 is provided at the lower end of the grinding device. The discharge channel 2 is inclined. A preheating component is provided in the discharge channel 2, and a dehumidifying component is provided in the preheating component;

[0023] The preheating component includes an inclined plate 3 provided in the discharge channel 2. A connecting frame 4 is fixedly connected in the discharge channel 2. The inclined plate 3 is slidably connected to the connecting frame 4. A stepped groove is provided on the inclined plate 3, and a plurality of push rods 5 are slidably connected to the inclined plate 3. A connecting rod 6 is fixedly connected to the push rod 5, and the connecting rod 6 penetrates through the inclined plate 3. A compression spring 7 is sleeved on the connecting rod 6, and the compression spring 7 is fixedly connected to the connecting frame 4. A driving motor 8 is also fixedly connected to the connecting frame 4. The output end of the driving motor 8 is fixedly connected to a cam 9. One end of the connecting rod 6 away from the push rod 5 is fixedly connected to a driving frame 10, and the driving frame 10 abuts against the cam 9;

[0024] In the above design, the inclined plate 3 is located directly below the discharge port of the grinding device body 1. After the grinding device body 1 grinds the raw material into powder, it falls on the inclined plate 3. At this time, the driving motor 8 runs to drive the cam 9 to rotate, and the cam 9 drives the driving frame 10 to move. The driving frame 10 cooperates with the compression spring 7 to drive the connecting rod 6 to reciprocate, and finally makes the connecting rod 6 reciprocate. In this state, the raw material falling on the inclined plate 3 cannot move directly downward along the inclined plate 3 after falling into the step groove, but is dispersed on the step groove. After the inclined plate 3 is used to heat and dry the raw material, the push rod 5 is used to drive the raw material to separate The step groove allows the raw materials to slide downward step by step, and finally the purpose of completely drying the raw materials is achieved. This design can make the inclined plate 3 and the raw materials have a larger heat exchange area, thereby improving the heat exchange efficiency. After the push rod 5 pushes the powdered raw materials out of the step groove, the completely dried raw materials fall back onto the inclined plate 3 at a slower speed, while the raw materials with a higher water content can fall onto the inclined plate 3 faster. On the other hand, the push rod 5 can also prevent the raw materials from accumulating in the step groove, thereby ensuring the fluidity of the raw materials, and allowing the dried raw materials to be quickly discharged, thereby preventing the raw materials retained on the inclined plate 3 from affecting the subsequent drying effect.

[0025] Furthermore, the dehumidification assembly includes a condensation plate 11 embedded in the discharge channel 2, a plurality of capillary grooves are provided on the lower surface of the condensation plate 11, and a water receiving shell 12 is fixedly connected to the lower end of the condensation plate 11, the water receiving shell 12 is connected to a drain pipe 13, and the drain pipe 13 runs through the discharge channel 2;

[0026] In this design, the condensation plate 11 is arranged directly above the inclined plate 3 and continues to extend upward along the discharge channel 2. After the raw material is heated and dried by the inclined plate 3, the temperature of the generated water vapor is relatively high. The condensation plate 11 is used to quickly condense the water vapor, and the capillary grooves can adsorb the condensed water on the condensation plate 11 and make the condensed water flow downward along the inclined plate 3 into the water receiving shell 12, thereby preventing the condensed water from dripping onto the inclined plate 3 and causing the raw material to become damp.

[0027] Furthermore, a plurality of sink grooves are provided on the inclined plate 3, and a heating device 14 is embedded in the sink grooves, wherein the sink grooves are arranged at positions close to the step grooves, and the heating device 14 can be a PTC heater or a resistance heater.

[0028] Furthermore, a through hole 15 is provided on the inclined plate 3, and the connecting rod 6 is arranged through the through hole 15. An inclined groove 16 is provided on the inner wall of one side of the through hole 15, and a stopper 17 is provided in the inclined groove 16. A protrusion 18 is fixedly connected to the side wall of the connecting rod 6, and the protrusion 18 is slidably connected to the inclined groove 16, and the protrusion 18 is made of elastic material, wherein the sliding stroke of the inclined plate 3 on the connecting frame 4 is smaller than the reciprocating stroke of the connecting rod 6;

[0029] In this design, the inclined groove 16 is provided to cooperate with the stopper 17 and the protrusion 18, so that when the connecting rod 6 reciprocates, the inclined plate 3 also reciprocates with the movement of the connecting rod 6, so that the inclined plate 3 will shake to a certain extent, so that the completely dried raw materials will be lifted up and fall downward, thereby increasing the discharge speed of the completely dried raw materials and avoiding the mixing of the completely dried raw materials with the undried raw materials to affect the heat exchange efficiency. On the other hand, it can also improve the utilization rate of thermal energy and reduce the energy consumption of the drying equipment.

[0030] Furthermore, a semiconductor refrigeration device is disposed on the upper surface of the condensation plate 11 .

[0031] Furthermore, a clearance opening is opened on the lower surface of the discharge channel 2, and the drive motor 8 is arranged in the clearance opening. The clearance opening is provided to provide the drive motor 8 with a better working environment. The drive motor 8 is arranged outside the discharge channel 2 to facilitate the heat dissipation of the drive motor 8 itself.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
