[0002] There are several modes of dryers, including belt drying, drum drying, box drying, tower drying, etc. The heat sources include coal, electricity, gas, etc. The materials can be dried in hot air flow and radiation drying. The hot air flow drying method is to use the hot air flow to move from the tail to the front, fully contact with the material, and fully utilize the heat transfer through heat conduction, convection, and radiation; the heat energy is directly transferred to the material, so that the moisture contained in the material is continuously evaporated, thereby drying the material.

[0003] The air supply device of the existing dryer usually adopts a volute fan to transport the outside air through the air duct to the heating device for heating, and then transport it to the dryer for use. The existing volute fan is usually directly installed on the outside of the equipment. The volute fan is noisy when working, and the outside air contains some impurities and moisture. The moisture in the air directly transported to the heating device will lead to reduced heating efficiency. At the same time, impurities in the air will also damage the parts of the equipment and reduce the service life of the equipment. Utility Model Content

[0006] Furthermore, the filter assembly includes an activated carbon filter and an impurity filter. An installation groove is provided at one end of the isolation frame close to the air outlet, and the activated carbon filter is installed in the installation groove. Several groups of impurity filters are fixedly installed at one end of the isolation frame close to the air inlet.

[0007] Furthermore, the installation grooves are arranged on the isolation frame in a front-to-back manner, and two groups of activated carbon filters are installed in each group of the installation grooves. Handles are fixedly installed on the side walls of the activated carbon filters.

[0008] Furthermore, a plurality of groups of first baffles are detachably mounted on the front and rear side walls of the cover shell, and the positions of the first baffles correspond to the positions of the isolation frames.

[0010] Furthermore, a manhole is provided on the front and rear side walls of the cover shell, and the manhole is located between the isolation frame and the fan assembly. A second baffle is detachably installed at the manhole.

[0011] The beneficial effect of the present invention is that the design of the present invention is to arrange a cover on the outside of the fan assembly to isolate the noise generated by the operation of the fan assembly through the cover.
