[0002] The rapid development of modern industry has brought many material and social benefits to mankind. At the same time, it has also brought serious harm to the environment on which mankind depends for survival, especially in the aspect of a large amount of waste gas emissions. In order to protect the environment for human survival, it is quite necessary to formulate more stringent air emission standards, promote more advanced and efficient dust removal technologies, reduce the emissions of industrial dust, and thus improve the atmospheric environment. Filter bags are the key parts in the operation of bag filters. Filter bags have excellent chemical stability and heat resistance, are representatives of the highest performance in the filter material industry, and are also the highest-end varieties among all commonly used filter materials.

[0003] When producing filter bags, special materials need to be sprayed. After spraying, the fabric used for processing filter bags needs to be transported to a drying device for drying. However, the existing drying devices have relatively single functions and can only achieve drying, and cannot cool the dried fabric. As a result, the temperature of the dried fabric is relatively high and cannot be directly subjected to the next processing procedure, and it needs to be placed indoors for natural cooling manually, which greatly reduces the production efficiency. Summary of the Utility Model

[0012] An exhaust fan motor is fixed inside an exhaust fan box, and an exhaust fan blade located inside the exhaust fan box is fixed to the outer wall of the output shaft of the exhaust fan motor;

[0013] A transmission assembly is rotatably installed on one side of the box body. One end of the transmission assembly penetrates through the side wall of the box body and is located inside the cooling cavity. One end of the transmission assembly is power-connected to the output shaft of the exhaust fan motor, and several rotating fan blades are fixed to the transmission assembly;

[0014] An exhaust pipe, one end of which is communicated with the exhaust fan box.

[0015] Working principle:

[0016] Drive the exhaust fan motor to drive the exhaust fan blade to rotate, and draw the hot air in the cooling cavity into the exhaust fan box and discharge it through the exhaust pipe. Continuously draw out the hot air in the cooling cavity, so that the cold air from the outside continuously enters the cooling cavity, realizing the temperature reduction treatment in the cooling cavity. At the same time, the exhaust fan motor drives the transmission assembly to rotate, and the transmission assembly drives several rotating fan blades to rotate, thereby driving the air to flow rapidly through the rotating fan blades and increasing the cooling speed of the fabric.

[0017] The beneficial effects of the present utility model are as follows:
