A chain transmission is adopted between the conveyor belt and the transmission shaft.

The discharge device is located at the side level with the lowermost conveyor belt.

An air distributor is arranged under the conveyer belt on the lowest layer, and the air distributor is located at the air inlet.

A circulating fan is also provided at the bottom end of one side of the box, and the circulating fan communicates with the inside of the box through a circulating fan port.

The beneficial effects of the utility model are: the utility model is a solar belt dryer, which uses a solar heat collector to replace the heating device of the traditional dryer. This method of using solar energy resources as the heating device of the dryer has low energy consumption and is The pressure generated by the environment is also small, and the dried materials are not easily polluted; at the same time, three layers of conveyor belts are arranged inside the box, which makes the drying time longer and improves the drying effect.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model is a solar belt dryer, as shown in Figure 1, comprising a solar heat collector 1, the inlet end of the solar heat collector 1 is provided with an induced draft fan 2, and the air outlet end of the solar heat collector 1 passes through the air inlet Pipeline 3 is connected with the sidewall of box body 4, and the upper end face of box body 4 is connected with exhaust fan 9 by air outlet pipeline 8, and the bottom end of a side of box body 4 is provided with the air inlet 15 that is connected with air inlet pipeline 3, so The upper end surface of the box body 4 is provided with an air outlet 16 connected to the air outlet pipe 8; the inside of the box body 4 is provided with a multi-stage transmission device, as shown in Figure 2, the multi-stage transmission device is driven by the motor 5, and the multi-stage transmission device includes The conveyor belt 10 arranged in three layers from top to bottom is provided with a transmission shaft 12 at both ends of each layer of conveyor belt 10, and the transmission shaft 12 is driven by a motor 5, and a chain 13 is used for transmission between the conveyor belt 10 and the transmission shaft 12; The upper end surface is provided with a hopper 6, and the side of the box body 4 is provided with a discharge device 7, and the discharge device 7 is located at the horizontal side with the lowermost conveyor belt 10; the lowermost conveyor belt 10 is provided with an air distributor 11 to distribute the air. The device 11 is located at the air inlet 15; the bottom end of one side of the box body 4 is also provided with a circulation fan 14, and the circulation fan 14 communicates with the inside of the box body 4 through the circulation fan port 17.

Preferably, the solar belt heat collector of the present utility model adopts a honeycomb structure solar heat collector, and this heat collector is made of glass or plastic into a honeycomb structure, which can be used to prepare a non-permeable air heat collector heat absorbing plate and Convective heat transfer between the glass cover plates reduces heat loss from the heat absorbing plate behind.

When a solar belt dryer of the utility model is in use, the material to be dried is evenly added from the hopper 6, and the solar radiation energy passes through the glass cover plate of the solar heat collector 1 and is projected onto the heat absorption of the solar heat collector 1 On the plate, it is absorbed by the heat absorbing plate and converted into heat energy, which is used to heat the air in the solar collector 1 to make its temperature rise gradually; the induced draft fan 2 sends the hot air generated by the solar collector 1 into the box 4 , to transfer heat to the material to be dried; after the material enters the box body 4, it first falls on the conveyor belt 10 on the upper layer, and the conveyor belt 10 on the upper layer is driven by the motor 5 through the transmission shaft 12 to rotate, and then through the transmission of the chain 13, The material is turned over and poured into the conveyor belt 10 of the next layer in turn, and this process is repeated until the last layer is discharged from the discharge device 7; the hot air of a solar belt dryer of the utility model is blown into the bottom of the box body 4 Inside the box body 4, the air distributor 11 and the circulating fan 14 can improve the air flow state and make the hot air flow evenly, so that the hot air can fully contact with the material, thereby achieving the purpose of removing moisture.
