Detailed Description

The foregoing and other features, aspects and advantages of the present utility model will become more apparent from the following detailed description of the embodiments with reference to the accompanying drawings 1-5. The following embodiments are described in detail with reference to the drawings.

Exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

The first embodiment is a turbine induced draft fan with a filtering function, which comprises a base 1, wherein a filter box 2 and an induced draft fan body 3 are arranged on the base 1, the filter box 2 is connected with the induced draft fan body 3 through an auxiliary pipeline 4, a plurality of groups of installation grooves 5 are formed in the filter box 2, a filter plate 6 is arranged in each of the plurality of groups of installation grooves 5, the filter box 2 is rotationally connected with an auxiliary plate 7, a clamping plate 8 is slidingly connected on the auxiliary plate 7, an adjusting screw 9 rotationally connected with the auxiliary plate 7 is in threaded connection with the auxiliary plate 7, and a handle 10 is arranged at one end of the adjusting screw 9; the clamping plate 8 is provided with a compaction rubber block 15 corresponding to the filter plate 6, and the bottom of the base 1 is provided with damping rubber.

When the filter plate 6 needs to be replaced, the handle 10 is rotated firstly to drive the clamping plate 8 to slide along the inner side wall of the auxiliary plate 7, so that the clamping plate 8 is separated from the filter box 2, then the clamping plate 8 at the bottom is also separated from the filter box 2, as the two groups of auxiliary plates 7 are rotatably arranged on the side wall of the filter box 2, the auxiliary plates 7 are turned over, so that the upper auxiliary plates 7 are positioned at the upper end of the filter box 2, the bottom auxiliary plates 7 are positioned at the bottom of the filter box 2, and then the handle 10 arranged on the filter plate 6 is pulled, so that the filter plate 6 is pulled out of the filter box 2 for replacement and cleaning, after cleaning, the filter plate 6 is installed in the installation groove 5 of the filter box 2, then the two groups of auxiliary plates 7 are turned over to correspond to the filter plate 6, and the handle 10 is rotated, so that the clamping plate 8 is matched with the filter plate 6, so that the filter plate 6 is fixed in the filter box 2, and the filter plate 6 is replaced more conveniently, and is easy to operate and convenient to operate;
