Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bag filters, in particular to a hopper of a bag filter. Background Art
[0002] A bag filter is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified.
[0003] In the prior art, a hopper with multiple discharge openings is generally formed by welding multiple cut flat plates. The welding workload is large, the working hours are consumed, and the product quality is greatly affected by the welding quality. Not only the cost is high, but the yield is also low. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a hopper of a bag filter, which can solve the problems existing in the prior art, reduce the welding amount, and improve the production efficiency and product quality.
[0005] To achieve the above purpose, the solution of the utility model is:
[0006] A hopper of a bag filter includes a middle folding plate and side folding plates symmetrically arranged on both sides of the middle folding plate. The middle folding plate and the side folding plates enclose a hopper for the material to fall. The middle folding plate has two first plate members connected by folding at the top edge, and the first plate member is an inverted isosceles trapezoid. The side folding plate has a second plate member and a third plate member connected by folding at the side edge, and the second plate members are symmetrically arranged on both sides of the third plate member. One side of the second plate member away from the third plate member has a first connecting edge and a second connecting edge connected at the end, and the length of the second connecting edge is equal to the waist length of the first plate member. The first connecting edges on the same side of the two side folding plates are welded to form an integral structure, and the second connecting edges of each second plate member are welded to the side edges of the corresponding first plate member to form an integral structure.
[0007] An observation window is opened on the second plate member.
[0008] An observation window is opened on the third plate member.
[0009] After adopting the above technical solution, the utility model has the following technical effects:
[0010] By combining the folding process with the welding process, the present utility model realizes splitting the six flat plates of the original butt welding process into three folded plate parts, namely one middle folded plate and two side folded plates. This makes the originally long four welds between the six flat plates become the bending forming of the folded plate parts, greatly reducing the welding amount in butt welding production, significantly shortening the welding working hours, and reducing the adverse effects on parts during the welding process. At the same time, the folded plate structure itself has a certain bending strength, is easier to manufacture, has a smaller deformation amount during the welding process, and the whole structure is more stable.

The middle folding plate 1 and the side folding plates 2 enclose a hopper for the material to fall, that is, the shape enclosed by the middle folding plate 1 and the side folding plates 2 is funnel-shaped;
[0028] The middle folding plate 1 has two first plate members 11 connected by folding at the top edge, and the first plate member 11 is an inverted isosceles trapezoid;

The second plate members 21 are symmetrically arranged on both sides of the third plate member 22; on the side of the second plate member 21 away from the third plate member 22, there are a first connecting edge 211 and a second connecting edge 212 connected at the end, and the length of the second connecting edge 212 is equal to the waist length of the first plate member 11;
