This utility model discloses a dust removal mechanism for an automatic cutting bed, comprising: a cutting bed, an automatic cutter, a pair of retractors, a collection box, and a dust collection structure. This utility model relates to the field of cutting bed dust removal technology. During the operation of the cutting bed, the automatic cutter cuts the fabric on the retractors, with a concave mounting bracket positioned above it. The sealing hydraulic push rod inside the sealing concave block extends and retracts, causing the sealing convex block to rise and fall stably along the sealing concave block, squeezing and sealing the cutting bed to effectively prevent dust leakage. During cutting, the auxiliary dust removal component rises and falls with the automatic cutter, mounting the fabric. An air pump discharges gas from the inside of the well-shaped negative pressure pipe, and multiple J-shaped siphons guide air from the inside of the concave mounting bracket. The auxiliary dust removal component simultaneously performs negative pressure adsorption filtration, and the air is further processed by the filter component in the collection box.

This invention belongs to the field of ironmaking dust removal technology, specifically a dust removal device for the blast furnace ironmaking tapping area. It includes a frame and an inlet pipe, an outlet pipe, a filter box mechanism, a screen changing mechanism, and a fan mounted on the frame. The filter box mechanism includes a first box, a second box, and an opening / closing drive device. The screen changing mechanism includes a translation support, a translation drive device, a rotating support, a rotating drive device, and filter plates. The rotation of the rotating support allows one of the two filter plates to be selectively positioned between the first and second boxes, with the first and second boxes clamping the filter plate between them to form a sealed structure. This invention also provides a method for replacing the filter plates in the aforementioned blast furnace ironmaking tapping area dust removal device. This invention can automatically replace the in-use filter plates with spare ones, greatly reducing the downtime of the dust removal device and offering advantages such as good dust removal effect, low cost, and small space occupation.

The utility model provides a workpiece dust removal device, which belongs to the technical field of workpiece dust removal, and comprises a protection box, a quick dust removal assembly and an overturning assembly, the quick dust removal assembly comprises two support plates arranged at the top of the inner wall of the protection box, and a rotating rod is rotatably connected between the two support plates; the dust removal device has the advantages that gas generated by the air pump is fed into the connecting base through the connecting pipe, the gas is sprayed out through the spraying head by the connecting base, then dust removal is conducted on a workpiece, ion wind is generated by the ion fan, the gas is fed into the connecting base through the conveying pipe and sprayed out through the spraying head, ions can effectively cover the workpiece, and the dust removal efficiency is improved. And the torque motor rotates to drive the rotating rod to swing leftwards and rightwards in a circulating mode, the rotating rod rotates to drive the connecting base to swing, then the spraying head swings to clean the dust of the workpiece, the spraying head can be matched with a suction pump to suck away the dust, the working efficiency is improved, and therefore the purpose of rapid dust removal is achieved.
