Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments.
Examples
As shown in fig. 1 and 2, fig. 1 is a schematic top view of a main frame in an embodiment, and fig. 2 is a schematic front view of a filter in an embodiment.
The device comprises a main frame 10, wherein a hollow installation part 11 is arranged in the main frame 10, the installation part 11 comprises a step 12 which is arranged at the upper end of the main frame 10 and is close to the inner side, and a plurality of bag filters are detachably arranged in the installation part 11 of the main frame 10.
The bag filter includes mounting frame 21, and the bottom fixed of mounting frame 21 is provided with filter bag 22, and the open end and the mounting frame 21 fixed connection of filter bag 22, a plurality of bag filters are arranged and are placed in installation department 11, and mounting frame 21 is put on step 12 and can dismantle the connection through mounting 13.
The fixing member 13 is a threaded hole 14 formed in the step 12 and a bolt provided in the mounting frame 21 at a position corresponding to the threaded hole 14.
The filter bag 22 is made of non-woven fabrics or electrostatic cotton materials, and a plurality of bag filters in the installation part 11 are connected with the main frame 10 in a detachable mode, so that the individual filters can be detached or replaced conveniently.
During installation, each filter bag 22 sequentially passes through the installation part 11, the installation frame 21 is placed on the corresponding step 12, and then bolts on the installation frame 21 are screwed into threaded holes 14 formed in the step 12, so that the installation and the fixation of the bag filter are completed. When the bag filter is disassembled, the bolts of the single bag filter are unscrewed, and the bag filter is taken out.
Fig. 1, 2 and 3 show schematic top views of the main frame in the embodiment, fig. 2 shows schematic front views of the filter in the embodiment, and fig. 3 shows schematic top views of the filter in the embodiment.
