Detailed ways

Below in conjunction with the embodiment given with accompanying drawing, further illustrate the specific implementation of the present utility model. The utility model is not limited to the description of the following embodiments.

Example 1

As shown in Figures 1-3, this embodiment discloses a material drying chamber capable of reducing tail gas pollution, which is mainly used for drying crops. Specifically, it includes a drying chamber, a material support 10 arranged inside the drying chamber, and a hot air blower 9 fixedly arranged at the lower part of the drying chamber for supplying hot air to the inside of the drying chamber;

The drying chamber includes an outer wall 1 and an inner wall 2. The space between the outer wall 1 and the inner wall 2 forms an air channel 3 for gas to pass through. A plurality of air outlets 4 are arranged on the upper part of the inner wall 2 of the drying chamber. The air outlet 4 communicates with the air passage 3, and a plurality of exhaust fans 5 are arranged on the upper part of the outer wall 1. The exhaust fan 5 is fixedly connected with the air outlet 4 on the outer wall 1 .

Further, as shown in FIG. 2 , a partition 6 is provided in the air passage 3 , the upper end of the partition 6 is fixedly connected to the top of the air passage 3 , and the lower end of the partition 6 is 10 cm to 20 cm away from the bottom of the air passage 3 . The separator 6 divides the air channel 3 into a rotary air channel. When in use, a double-layer exhaust gas insulation layer is formed between the outer wall 1 and the inner wall 2, and during the rotary discharge process, the main impurities in the exhaust gas are in the rotary air channel. The bottom settles.

Further, in this embodiment, the drying chamber has doors that can be drawn to both sides.

Preferably, a material guide plate 11 arranged obliquely is arranged at the bottom of the air channel 3 , and a plurality of cleaning ports 7 are provided on the outer wall 1 on one side of the material guide plate 11 . The material guide plate 11 guides the large particle impurities contained in the exhaust gas to the ash cleaning port 7, which is convenient for centralized cleaning.

Preferably, in order to further reduce heat loss, the outer wall 1 is fixedly provided with a heat insulation layer. Further, the heat insulation layer adopts phenolic resin insulation board.

Preferably, a plurality of temperature and humidity sensors are fixedly installed in the drying chamber, and a display is fixedly installed outside the drying chamber, and the temperature and humidity sensors are connected to the display. Further, in some embodiments of the present utility model, a control module is also provided, the control module is connected to the control circuit of the hot air blower 9, and the temperature and humidity sensor is connected to the control module.
