Detailed Description

In order to facilitate a better understanding of the present invention, the present invention will be further described with reference to the following embodiments and drawings.

As shown in fig. 1. In this embodiment, the firecracker fuse-filling automatic drying system comprises two L-shaped drying chambers 1 with the same shape and size and the cross sections of the two L-shaped drying chambers are L-shaped, and the two L-shaped drying chambers are respectively provided with corresponding drying devices and the like. The two L-shaped drying chambers are symmetrically arranged in opposite directions, and are separated by a middle heat insulation coaming 8 which is approximate to a Z shape.

The L-shaped circulating current replacement zone 1b1 transversely protruding from the L of the two L-shaped drying chambers 1 is in airflow connection with one corresponding end of the L-shaped main current replacement zone 1a2 of the right L-shaped drying chamber through a plurality of axial flow fans 2; the L-shaped transversely-protruding circulation replacement zone 1a1 of the right L-shaped drying chamber is in airflow connection with one end of the L-shaped straight main flow replacement zone 1b2 of the left L-shaped drying chamber through a plurality of corresponding axial flow fans 2. The drying device 3 is arranged in the corresponding circular current displacement area which is projected in the L transverse direction. The drying device 3 may be constituted by an existing similar dryer.

The opposite end of the L-shaped drying chamber in the L-direction main flow replacement area is provided with a door 9. The drying baskets 4 can be stacked in layers in the circulation displacement zone and the mainstream displacement zone of the L-shaped drying chamber. The material basket 4 is then ducted and separated by the freestanding ducting frame panels 5 to provide more uniform air displacement drying. The drying basket 4 and the air inlet and outlet of the drying device can be spaced at a certain interval.

The L-shaped drying chamber is fully sealed by a heat insulation surrounding plate, and an air outlet 3b and an air inlet 3a of the drying device are respectively and directly connected with a circulation replacement area of the L-shaped drying chamber. After the drying materials (such as firecracker) 10 are loaded, the door of the L-shaped drying chamber is closed, the air in the drying zone forms repeated uniform internal circulation through the drying devices at the two opposite ends of the drying zone and the axial flow fan, and moisture and the like which are dehumidified and dried are discharged out through the liquid discharge pipe 7 of the drying device.

The circulation replacement area and the main flow replacement area are uniformly provided with temperature and/or humidity sensors connected with a controller of the drying device. The controller of the drying device is arranged outdoors. After setting relevant parameters including drying temperature, humidity and the like, the controller automatically works and operates. The structure of the drying system and the circulating drying mode thereof have higher drying efficiency and reduce energy waste.

The width of the circulating displacement zone in the direction of gas flow is smaller than the corresponding width of the main flow displacement zone. To obtain a relatively better displacement of the circulating gas stream.

In another embodiment, as shown in fig. 2 and 3. The drying device is arranged outside the circulation replacement area, and an air inlet and an air outlet of the drying device are respectively led into the circulation replacement area through the heat insulation coaming holes of the circulation replacement area. The operation is safer. The drying device comprises a heat pump host 31, an air inlet buffer chamber 10 and an air return buffer chamber 11. The inlet and the outlet of the heat pump host are respectively connected with the air inlet buffer chamber 10, the air return buffer chamber 11 and the like. The outlet of the return air buffer chamber is an air outlet 3b of the heat pump host, and a plurality of circulating air outlet fans 13 are arranged at the outlet of the return air buffer chamber. The inlet of the air inlet buffer chamber forms an air inlet 3a of the heat pump main machine, the inlet of the air inlet buffer chamber is provided with a plurality of circulating air inlet fans, and the inlet of the air inlet buffer chamber is provided with a protective mesh enclosure 18. The air inlet buffer chamber is connected with a moisture removal fan 15 through a corresponding valve 16, and a corresponding fresh air supplement fan 17 is arranged in the air return buffer chamber through a corresponding valve. When the material humidity is too big or other needs circumstances, can carry out the hydrofuge through the hydrofuge fan, if need its new trend benefit fan can carry out the air supplement cooperation. Under the normal operation condition, the drying area is in closed internal circulation operation. The heat pump host can be related heat pump host of the prior art. The drying device is used for exhausting moisture and/or supplementing air, so that the uniform replacement of the circulating gas of the L-shaped drying chamber can be kept, and the generation of uneven disturbance is avoided. The rest of the structure and the corresponding drying operation mode of the embodiment can be similar to the above embodiment.

In another embodiment, the air inlet buffer chamber and the air return buffer chamber are respectively provided with a pressure sensor. The pressure sensor may be connected to an outdoor display. When the air inlet pressure and the air return pressure are unbalanced, the air inlet pressure and the air return pressure can be used for judging whether resistance exists in the air inlet or the air outlet. The rest of the structure and the corresponding drying operation mode of this embodiment can be similar to those of embodiment 2.
