The filter is a stacked filter 1, including a medium-efficiency bag filter 12 and a pre-filter 11 nested inside the medium-efficiency bag filter 12 from top to bottom. The outer frame of the stacked filter 1 is installed in the mounting rail and fixedly connected to the mounting rail by the quick clamp 21. Both the pre-filter 11 and the medium-efficiency bag filter 12 are bag filters, but they differ in the size of dust particles they intercept. The pre-filter 11 is the first stage of filtration, typically mainly intercepting large dust particles larger than 5μm, while the medium-efficiency bag filter 12 is the second stage of filtration, typically mainly intercepting dust particles larger than 1μm. The primary bag filter 11 and the medium-efficiency bag filter 12, when stacked, function as a single unit. Their frames are also stacked together, forming the outer frame of the stacked filter 1. The outer frame of the stacked filter 1 is slid into the mounting track. Once in the designated position, the quick-clamp 211 of the quick-clamp 21 presses the outer frame firmly into the mounting track, thus quickly locking the stacked filter 1 to the filter mounting assembly 2.

Whether the primary bag filter 11 or the medium bag filter 12, the particles screened will fall at the bottom of the filter bag, and the side of the filter bag serves as a hot air channel. After filtration, the clean hot air is transported to the dehumidification heat pump.

[0037] The embodiment adopts integrated bag nesting design, the primary bag filter is nested in the medium bag filter to form a double-layer filtering structure, and after nesting, the two are equivalent to a whole, and when maintenance and replacement are performed, the whole is simultaneously disassembled and assembled, so that the disassembly and assembly process is greatly simplified. In addition, the stacked design not only does not increase the space occupation, but also saves space compared with the traditional filtering device, and simultaneously realizes the double filtering effect.

[0038] The dust collected by the embodiment is deposited at the bottom of the filter bag, and the side surface for filtering hot air is not affected at all. The filtering area is much larger than that of the traditional filtering device, the filter replacement frequency is much lower than that of the traditional filtering device, and the late equipment maintenance cost is greatly reduced. At the same time, the utility model effectively reduces the shutdown frequency of the drying machine, significantly prolongs the continuous operation period of the drying machine, and effectively reduces the enterprise operating cost.
