Description
Technical Field
[0001] The present application relates to the technical field of dust removal, and in particular to a dust removal device for sheet metal processing. Background Art
[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6 mm).
[0003] In order to improve the quality of sheet metal workpieces, sheet metal workpieces and other workpieces are often ground and polished during their production process.
[0004] At present, when grinding a workpiece, the workpiece is generally placed on a workbench, and a worker uses a handheld grinder to grind and polish the workpiece placed on the workbench. However, during the polishing process of grinding and polishing the workpiece, metal debris falling off the workpiece easily generates a large amount of metal dust.
[0005] A large amount of metal dust can be easily inhaled by nearby workers, which may affect their health. Utility Model Content
[0006] In order to reduce the metal dust content near workers, the present application provides a sheet metal processing dust removal device.
[0007] The present application provides a sheet metal processing dust removal device that adopts the following technical solution:
[0008] A sheet metal processing dust removal device, comprising
[0009] Workbench;
[0010] A dust suction assembly, the dust suction assembly comprising a dust suction seat arranged on the workbench, a fan and a dust suction pipe arranged near the workbench, one end of the dust suction pipe is installed on the dust suction seat, and the other end of the dust suction pipe is connected to the fan;
[0011] A collecting assembly comprises a collecting box arranged in the middle of the dust suction pipe and a cleaning part arranged inside the collecting box. The collecting box is connected to the dust suction pipe, and the cleaning part is used for filtering and collecting metal dust inside the collecting box.
[0012] By adopting the above technical solution, when processing a workpiece, the workpiece is placed on the top of the workbench and supported by the workbench. The dust collector is placed on the workbench, and the relative position of the dust collector and the workbench is adjusted according to the position where dust needs to be absorbed, so as to adjust the range of dust absorption.
[0013] Since the collection box is installed in the middle of the dust collection pipe, when collecting the dust generated by the workpiece processing, the fan causes the dust to enter the dust collection pipe from the dust collection seat and then into the collection box. The dust inside the collection box is filtered and collected by the cleaning part inside the collection box, and the filtered gas is discharged from the fan, thereby reducing the dust content near the staff.
[0014] Optionally, the dust suction seat includes a dust suction box arranged on the top of the workbench and a displacement part arranged on the dust suction box for moving the dust suction box, the dust suction box is connected to the dust suction pipe, and a plurality of dust suction holes are opened on the dust suction box.
[0015] By adopting the above technical solution, when the position of the dust box needs to be adjusted, the dust box is moved on the workbench through the displacement part. The dust box fixes the dust pipe, and when dust needs to be absorbed, the dust enters the dust box through the dust suction hole on the dust box, and then enters the dust pipe from the dust box, so as to facilitate the absorption of dust near the staff.
[0016] Optionally, a guide groove is provided on the top of the workbench, and the displacement portion includes a displacement rod vertically arranged at the bottom of the dust box, the displacement rod is partially placed inside the guide groove, and the displacement rod and the guide groove are slidably matched.
[0017] By adopting the above technical solution, the displacement rod is partially placed inside the guide groove, and the displacement rod and the guide groove are slidably matched. During the movement of the dust box, the guide groove guides and limits the dust box through the displacement rod, thereby improving the stability of the movement of the dust box.
[0018] Optionally, the displacement part further includes a displacement bead arranged at the bottom of the dust collection box, and the displacement bead and the workbench are in rolling cooperation.
[0019] By adopting the above technical solution, due to the rolling cooperation between the displacement beads and the workbench, when the dust box is moved, the friction resistance between the dust box and the workbench is reduced, thereby improving the convenience of moving the dust box.
[0020] Optionally, the cleaning part includes a collection rack arranged inside the collection box and a filter cloth arranged on the collection rack, the filter cloth divides the interior of the collection box into a filtered area and an area to be filtered, the dust suction pipe is connected to the area to be filtered, and the fan is connected to the filtered area.
[0021] By adopting the above technical solution, the collection frame supports and positions the filter cloth. After the dust-containing gas enters the collection box, the dust inside the collection frame is filtered by the filter cloth, thereby reducing the dust content in the air.
[0022] Optionally, a plurality of filter frames are provided on the collecting rack, and the filter cloth is attached to the filter frames.
[0023] By adopting the above technical solution, since the filter cloth is attached to the filter frame, the filter cloth increases the filtering range of the dust inside the collection box through the filter frame, thereby improving the efficiency of filtering the dust inside the collection box.
[0024] Optionally, the collection assembly also includes a pressure measuring part arranged on the collection box, the pressure measuring part includes a pressure gauge, a first pressure measuring tube and a second pressure measuring tube connected to the pressure gauge at one end, the first pressure measuring tube is connected to the area to be filtered, and the second pressure measuring tube is connected to the filtered area.
[0025] By adopting the above technical solution, since the first pressure measuring tube is connected to the area to be filtered, the second pressure measuring tube is connected to the filtered area, and the first pressure measuring tube and the second pressure measuring tube are both connected to the pressure gauge, it is convenient to judge the pressure difference between the area to be filtered and the filtered area through the pressure gauge. After the filter cloth filters the dust in the air for a long time, the dust in the air will easily clog the filter cloth, resulting in a decrease in the filtering capacity of the filter cloth. At this time, the pressure difference between the area to be filtered and the filtered area is significantly different from the initial pressure difference, which makes it convenient for the staff to clean the filter cloth in time and improve the effect of the filter cloth on filtering air dust.
[0026] Optionally, a control valve is installed on the dust suction pipe between the dust suction box and the collection box.
[0027] By adopting the above technical solution, when the filter cloth needs to be cleaned, the control valve is closed, and air is sucked and exhausted into the collection box through the fan intermittently, thereby making it easier to blow off the dust attached to the filter cloth, thereby improving the filtering effect of the filter cloth.
[0028] In summary, the present application includes at least one of the following beneficial technical effects:
[0029] 1. When processing the workpiece, place the workpiece on the top of the workbench and support the workpiece through the workbench. Place the dust collector on the workbench and adjust the relative position of the dust collector and the workbench according to the position where the dust needs to be absorbed, so as to adjust the range of dust absorption.
[0030] Since the collection box is installed in the middle of the dust collection pipe, when collecting the dust generated by the workpiece processing, the fan causes the dust to enter the dust collection pipe from the dust collection seat and then into the collection box. The dust inside the collection box is filtered and collected by the cleaning part inside the collection box, and the filtered gas is discharged from the fan, thereby reducing the dust content near the staff.
[0031] 2. Since the first pressure measuring tube is connected to the area to be filtered, the second pressure measuring tube is connected to the filtered area, and both the first pressure measuring tube and the second pressure measuring tube are connected to the pressure gauge, it is convenient to judge the pressure difference between the area to be filtered and the filtered area through the pressure gauge. After the filter cloth has been filtering the dust in the air for a long time, the dust in the air will easily clog the filter cloth, resulting in a decrease in the filtering capacity of the filter cloth. At this time, the pressure difference between the area to be filtered and the filtered area is significantly different from the initial pressure difference, which makes it convenient for the staff to clean the filter cloth in time and improve the effect of the filter cloth on filtering air dust.
