[0028] As attached Figure 1 To Attachment Figure 2 As shown: the blowing part 1 includes a motor 11, one side of the motor 11 is drivingly connected to a fan 12, a connection box 13 is fixedly connected to the air outlet of the fan 12, the connection box 13 is fixedly connected to the dehumidification part 2, the motor 11 can drive the fan 12 to work, thereby blowing out air flow, the air flow enters the dehumidification part 2 through the connection box 13 to be dehumidified, and the front side of the connection box 13 is also fixedly connected to a pipe three 83.
[0029] As attached Figure 1 To Attachment Figure 4 As shown: the dehumidification section 2 includes a dehumidification box 21, which is fixedly connected to the connection box 13. A plurality of heating rods 22 are fixedly connected inside the dehumidification box 21. The dehumidification section 2 can use electric heating or gas heating, which can be selected according to needs. The heating rods 22 can remove moisture from the airflow blown out by the fan 12. It is worth noting that during the dehumidification process, the heating rods 22 will heat up the airflow, but after the airflow is heated, the temperature is still much lower than the temperature of the material just falling from the discharger 8. Therefore, the airflow can dry and cool the material.
[0030] As attached Figure 1 To Attachment Figure 4 As shown: the airflow regulating part 3 includes an adjusting box 31, and the adjusting box 31 is fixed between the dehumidification box 21 and the wind bin 4.

The wind flow blows the materials on the conveyor belt 74 upward and dries the materials. The over-crushed materials will be blown upward by the wind flow due to their low weight. Due to the special structure of the return air cover 51, these crushed materials will be blown into the pipe 1 52. After being filtered by the filter screen plate 53, the crushed materials enter the pipe 2 54, and then enter the cyclone separator 81 for further processing. Relatively complete materials cannot enter the pipe 2 54.
[0033] As attached Figure 1 To Attachment Figure 4 As shown: the feeding part 7 includes a motor 3 71, and the motor 3 71 is fixed on the top of the discharge bin 41. A driven shaft 2 72 is rotatably connected in the discharge bin 41. The output end of the motor 3 71 is connected to the driven shaft 2 72 through gears and a toothed chain transmission.

The material in the discharger 6 falls onto the conveyor belt 74, and is then transported to the discharge bin 41 by the conveyor belt 74.
[0034] As attached Figure 1 To Attachment Figure 2 As shown: the cleaning reflux section 8 includes a cyclone separator 81, which is a prior art. The air inlet of the cyclone separator 81 is fixedly connected to the pipe 2 54, and the bottom of the cyclone separator 81 is spirally connected with a dust box 82. When the debris in the dust box 82 reaches a certain amount, the dust box 82 can be removed for cleaning and then reinstalled for use. The air outlet at the top of the cyclone separator 81 is fixedly connected with a pipe 3 83, and the other end of the pipe 3 83 is fixedly connected to the connecting box 13. A one-way valve is provided at one end of the pipe 3 83 close to the connecting box 13, so that the airflow can only enter the connecting box 13 from the pipe 3 83. The airflow in the pipe 2 5 enters the cyclone separator 81, and the mixed materials therein are stripped out and fall into the dust box 82, so that the airflow can be cleaned. The cleaned airflow re-enters the connecting box 13, and then enters the dehumidification section 2 to be dehumidified, so that the airflow can be reused and the material is cleaned.
[0035] As attached Figure 1 To Attachment Figure 2As shown: the screening part 9 includes a screening box 91, which is hollow and has an open top. The screening box 91 is arranged directly below the discharge pipe 42, and a motor 92 is fixedly connected to the front outer wall of the screening box 91. A screening barrel 93 is rotatably connected inside the screening box 91, and the motor 92 is transmission-connected to the screening barrel 93. A plurality of evenly arranged screening holes are provided on the barrel wall of the screening barrel 93, and a movable door that can be opened and closed is hingedly provided. When the movable door is opened, the material in the discharge pipe 42 falls into the screening barrel 93. When the movable door is closed, the motor 92 can drive the screening barrel 93 to rotate, thereby screening out the broken materials.
[0036] Working method: put the material into the discharger 6, start the motor 11, make the fan 12 work to blow air into the wind bin 4, when the wind flows through the dehumidification part 2, it is heated by the heating rod 22 to dehumidify, start the motor 2 32, make the driven shaft 1 33 rotate, drive the baffle 34 to rotate, so as to adjust the size of the wind force, after the wind flows into the wind bin 4, it blows the material on the conveyor belt 74 upward, among which the smaller material is carried by the wind flow into the pipe 1 52, and after being filtered by the filter plate 52, the smaller broken material enters the pipe 2 with the wind flow 54, and then enters the cyclone separator 81, the crushed materials fall into the dust box 82, and the cleaned air flow enters the connecting box 13 through the pipe three 83, and the motor three 71 is started to make the conveyor belt 74 work, and the relatively complete materials are transported to the discharge bin 41, and the valve 43 and the movable door on the screening barrel 93 are opened, and the materials enter the screening barrel 93 through the discharge pipe 42, and the valve 43 and the movable door on the screening barrel 93 are closed, and the motor four 92 is started to rotate the screening barrel 93, and the mixed crushed materials are screened out from the screen holes.
[0037] In the present device, since the wind flows from bottom to top in the silo 4, and the return air hood 51 is in the shape of a pyramid and the valve 43 is in the normally closed state, the wind can enter the pipe 1 52 from the silo 4, and enter the pipe 2 54 and the clean return part 8 after being filtered by the filter plate 53. Since a one-way valve is provided at one end of the pipe 3 83 close to the connection box 13, the airflow can only enter the connection box 13 from the pipe 3 83, and since the air outlet of the fan 12 is connected to the connection box 13, the flow rate is large and the pressure is low. According to the Bernoulli principle, the airflow in the pipe 3 83 can be guided to flow to the connection box 13, thereby completing the airflow circulation and completing the airflow cleaning work during the airflow circulation.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should fall within the technical scope of the present invention.
