[0035] The present invention provides a silicon material drying device. Figure 1-Figure 6 As shown, the silicon material drying treatment device comprises:

[0036] The material inlet and outlet assembly 100 includes a material inlet bin 110 and a material outlet 120, wherein the material inlet bin 110 is located above the material outlet 120;

[0037] A drying chamber 200, wherein the interior of the drying chamber 200 is divided into a primary drying chamber 210 and a secondary drying chamber 220, and a guide chamber 300 is provided at one end of the drying chamber 200 away from the material inlet and outlet assembly 100;

[0038] A first conveyor belt 410 and a second conveyor belt 420. The material fed into the feed bin 110 passes through the primary drying chamber 210 to the guide chamber 300 under the conveying action of the first conveyor belt 410, and slides down to the second conveyor belt 420 under the action of the guide plate 310 provided in the guide chamber 300. The second conveyor belt 420 carries the material through the secondary drying chamber 220 and arrives at the discharge port 120.

[0039] In the present application, the first conveyor belt 410 is arranged in the first-level drying chamber 210, and the second conveyor belt 420 is arranged in the second-level drying chamber 220. Several groups of microwave heating components are arranged on the top of the first-level drying chamber 210 and the second-level drying chamber 220. The microwave heating components are prior art equipment. Here, the first-level drying chamber 210 and the second-level drying chamber 220 are divided into groups of microwave resonance chambers, and exhaust ports are arranged on the tops of the microwave resonance chambers. The water vapor generated during the heating process will be discharged from the exhaust ports under the action of the fan. In the present application, the technical principle adopted by the first-level drying chamber 210 and the second-level drying chamber 220 is the same as the structure of the prior art equipment. Here, two groups of tunnel equipment are superimposed to form a double-layer structure. The drying chamber 200 adopts a double-layer structure to carry out reciprocating drying of materials, which can effectively shorten the length of the equipment and reduce the plant land occupied by the equipment.

[0040] In the present application, the feed bin 110 extends relative to the discharge port 120 and is shielded above the discharge port 120 to prevent the material from falling into the discharge port 120 during the feeding process. The discharge port 120 adopts a slope design to cooperate with a collection trough (not shown in the figure) to collect materials. Here, the first conveyor belt 410 and the second conveyor belt 420 move in opposite directions. Finally, the material fed into the feed bin 110 will be output from the discharge port 120 after drying.

[0041] As a preferred implementation in this embodiment, the top of the guide plate 310 is supported below the first conveyor belt 410, and the bottom of the guide plate 310 is located above the second conveyor belt 420; the material will automatically slide onto the second conveyor belt 420 under the characteristics of the slope structure;

[0042] The guide plate 310 includes a slide plate 311 and a disturbance rod 312. Guard plates are provided on both sides of the slide plate 311 to prevent the material from slipping off. The disturbance rod 312 is composed of a main rod and a plurality of thin rods. Here, the thin rods are arranged perpendicular to the slide plate 311. The thin rods are not used to screen the material. The kinetic energy of the material itself is mainly used to collide with the thin rods to loosen the bonded materials. At the same time, the material is moved to achieve the effect of shape transformation.

[0043] As a preferred implementation in this embodiment, a sealing door is provided between the secondary drying chamber 220 and the guide chamber 300, and a swinging material assembly 320 is provided on the sealing door;

The sliding plate 322 drives the scraper 323 to move. The sliding plate 322 slides perpendicularly to the forward direction of the second conveyor belt 420. The scraper 323 slides parallel to the forward direction of the second conveyor belt 420. The scraper 323 will evenly disperse the material forwarded by the second conveyor belt 420 to reduce the concentration of the material, further change the shape of the material during the pushing process, and achieve the effect of turning the material.

[0045] The sliding plate 322 is provided with a fixing screw, a mounting hole 3221 and a fixing groove 3222, the scraper 323 is inserted into the fixing groove 3222, and the fixing screw extending from the mounting hole 3221 to the fixing groove 3222 is installed on the scraper 323;
