Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of baghouse dust collectors, specifically to a dust collector bag frame. Background Technology
[0002] Baghouse dust collectors are a type of filtration dust collector that separates and collects dust by passing dust-laden airflow through filter media. The filter bags used are made of fabric or felt woven from synthetic fibers, natural fibers, or glass fibers. Baghouse dust collectors are classified into internal filtration and external filtration types based on the direction of the dust-laden airflow entering the filter bags. External filtration baghouse dust collectors require an inner lining of the filter bags with a filter bag skeleton to prevent the bags from collapsing under negative pressure and becoming inoperable. Filter bags can be classified into round and flat shapes, and the shape of the filter bag skeleton is matched accordingly.
[0003] Circular dust collector bags come in two shapes: cylindrical and pleated. Pleated dust collector bags, for the same dimensions, significantly increase the filtration area compared to cylindrical bags. Dust collectors using pleated bags have a larger dust collection capacity for the same volume compared to those using cylindrical bags. However, existing pleated dust collector bag frames have a problem: dust within the pleats is difficult to remove during cleaning. Utility Model Content
[0004] Therefore, this utility model proposes a dust collector bag frame to improve the problems existing in the above-mentioned prior art.
[0005] The technical solution of this utility model is as follows:
[0006] A dust collector bag frame includes an upper cage, an inner frame, and an outer frame. The lower part of the upper cage is connected to the outer frame. The inner frame is disposed inside the upper cage and the outer frame, and the inner frame is coaxial with the upper cage. The upper cage includes an upper end cap and a lower cylindrical cage. The end cap is a disc with a central through hole and a downward-facing annular groove. The inner frame includes an upper push-pull rod and a lower cylindrical frame. The outer frame includes a frame beam, a first connecting member, a second connecting member, and a third connecting member. One end of the first connecting member is hinged to the lower part of the upper cage and the other end is hinged to the upper end of the frame beam. One end of the second connecting member is hinged to the upper part of the inner frame and the other end is hinged to the upper end of the frame beam. One end of the third connecting member is hinged to the lower part of the inner frame and the other end is hinged to the lower end of the frame beam. The second and third connecting members are of equal length, and the frame beam is of equal length to the cylindrical frame.
[0007] A preferred technical solution is that the barrel-shaped cage, inner frame, and outer frame of the upper cage are all made of metal wire; the frame beam is a long strip-shaped U-shape; the barrel-shaped cage includes a first ring rib and a first vertical rib, the first ring rib is concentric with the end cap and the plane in which they are located is parallel, and the two ends of the first vertical rib are respectively connected to the end cap and the first ring rib; the cylindrical frame of the inner frame includes a second ring rib and a second vertical rib, the number of second ring ribs is two, and the two ends of the second vertical rib are respectively connected to the second ring rib; the first connector and the third connector have hook-shaped ends and an H-shaped middle, the second connector has hook-shaped ends and a tuning fork-shaped middle, and the frame beam, the first connector, the second connector, and the third connector are symmetrically distributed circumferentially.
[0008] A preferred technical solution is that the upper end of the first connector is hinged to the connection between the first ring rib and the first vertical rib, the upper end of the second connector is hinged to the connection between the upper second ring rib and the second vertical rib, and the upper end of the third connector is hinged to the connection between the lower second ring rib and the second vertical rib.
[0009] A preferred technical solution is that the number of the beam, the first connector, the second connector, and the third connector is the same, which is five or more.
[0010] A preferred technical solution is that the second ring rib is provided with a short strip connecting its center, and one end of the push-pull rod is connected to the center of the second ring rib, while the other end extends out of the center through hole of the end cap.
[0011] The working principle and beneficial effects of this utility model are as follows:
[0012] The dust collector bag frame provided by this utility model has two working positions for the push-pull rod during use: an upper stop and a lower stop. When it is at the upper stop, the entire dust collector bag frame is a cylindrical shape with a through diameter at both ends. In this state, the dust collector bag frame is installed into the filter bag. The dust collector bag frame is inserted into the annular groove of the rear end cover, pressing the elastic ring at the top of the filter bag. The end cover and the perforated plate cooperate to clamp the neck of the filter bag to prevent air leakage, thus completing the installation. During normal use, the push-pull rod is at the upper stop. When dust removal is required, the mechanism for raising and lowering the push-pull rod is pushed to the lower stop. When the push-pull rod is at the lower stop, the lower part of the dust collector bag frame opens, expanding the filter bag, and then dust removal is carried out using reverse airflow or pulse airflow.
