Example 1
As shown in the figure: a high-efficiency dust-removing filter bag with a dust collecting function comprises a top plate 1, a bottom plate 2 and a filter bag 3 positioned between the top plate 1 and the bottom plate 2, wherein a ventilation hole 1.1 is formed in the top plate 1, the filter bag 3 comprises a bag barrel, a circular folded edge positioned at the top end of the bag barrel and a plurality of supporting circular rings 3.2 which are surrounded by the bag barrel and fixed on the inner side wall of the bag barrel, a circular clamping plate 1.2 is further fixed at the top plate 1, and the circular folded edge is clamped between the clamping plate 1.2 and the top plate 1; the bottom of the bag cylinder 3 is open, the bottom of the bag cylinder 3 is also fixedly connected with a circular first annular plate 3.3, the first annular plate 3.3 is connected with a lifting plate 2.4 positioned below the bottom plate 2 through a plurality of first pull ropes 3.4, a circular iron second annular plate 4 is arranged below the first annular plate 3.3, a plurality of bumps 4.1 are fixed on the side surface of the second annular plate 4, a second pull rope 4.2 and an elastic pull rope 4.3 are connected between each bump 4.1 and the first annular plate 3, a lifting cylinder 2.3 is connected between the lifting plate 2.4 and the bottom plate 2, an electric winding device 2.1 is further fixed at the bottom plate 2, a movable circular plate 4.4 surrounded by the second annular plate 4 is fixed at the second annular plate 4, a discharging through hole is formed at the movable circular plate 4.4, a discharging through hole is connected with a discharging pipe 5.1, and a flexible collecting cylinder 5 is connected between the first annular plate 3.3 and the discharging through hole; the lower surface of the first annular plate 3.3 is provided with a first annular groove, a second annular groove is arranged in the first annular groove, an annular magnet 3.5 is fixedly mounted in the second annular groove, the second annular plate 4 can be accommodated in the first annular groove, a third pull rope 2.2 is wound at the position of the electric winding device 2.1, and the end part of the third pull rope 2.2 is fixedly connected with the movable circular plate 4.4.
4-6 lugs 4.1 are arranged on the second annular plate 4, and all lugs 4.1 on the second annular plate 4 are distributed in a circular ring shape at equal intervals. The lifter plate 2.4 includes a central circular plate 2.4.1, an outer circular plate 2.4.3 and a plurality of radial connecting plates 2.4.2 connected between the central circular plate 2.4.1 and the outer circular plate 2.4.3. The blanking pipe 5.1 is provided with a blanking valve (not shown). The first pull rope 3.4 and the second pull rope 4.2 are not elastic, and the length of the second pull rope 4.2 is less than 25cm. The clamping plate 1.2 is fixed with the top plate 1 through bolts.
As shown in the figure, the dust removal filter bag, the top plate and the bottom plate of the dust removal filter bag are fixed on a frame (not shown) of equipment. During normal dust removal, as shown in fig. 1-2, the second annular plate is attracted by the magnets in the first annular plate (the first annular plate is thicker, so that a larger-volume annular magnet can be arranged, and the second annular plate is thinner and lighter, so that the second annular plate can be stably attracted by the annular magnet), and the flexible collecting cylinder is clamped between the first annular plate and the second annular plate. And lift cylinder makes the lifter plate be in lower position this moment for a plurality of stay cords are straightened a bag section of thick bamboo and are tightened, have a plurality of support rings in the bag section of thick bamboo, and do not have the montant, thereby a bag section of thick bamboo is tightened, is used for removing dust.
When dust removal is finished and ash removal is needed, the lifting cylinder enables the lifting plate to ascend, so that the first pull rope is loose (as shown in figures 3-4), the electric winding device winds the third pull rope, so that the second annular plate descends, the descending maximum distance of the second annular plate is limited by the second pull rope (as shown in figures 5-8), then the electric winding device releases the rope for a certain distance, so that the second annular plate ascends under the elastic force of the elastic pull rope, then the electric winding device quickly winds the rope, and after the electric winding device arrives at a certain position, the electric winding device immediately and quickly stops the rope to play a role similar to a shaking bag barrel, so that dust attached to the inner side wall of the filter bag falls into the flexible collecting barrel, and the actions can be repeated for several times, so that the dust can be shaken off as far as possible. After the ash removal is finished, the valve can be opened, and the negative pressure induced draft sucks away the dust in the flexible collecting cylinder. Then the filter bag is recovered to the state of figure 1 and is continuously used for dust removal.
Example 2
As shown in fig. 9, it is a structure of another embodiment, and the main difference between embodiment 2 and embodiment 1 is that embodiment 2 arranges the filter bags in a row, so that a larger dust removing effect can be obtained, and in embodiment 2, all the feeding pipes can be connected to one feeding main pipe in parallel, so that the feeding main pipe can suck air under negative pressure (and at this time, it is not necessary to arrange a valve at each feeding pipe, no valve can be arranged at the feeding pipe, and only one general valve is arranged at the main pipe), so that the dust in the flexible collecting cylinder can be sucked away from the feeding main pipe together.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
