The device comprises a movable supporting box, a dust collecting cover, a telescopic dust collection pipe, a negative pressure dust collection apparatus, a cyclone dust collector, a dust collecting bin, a liquid filtering apparatus and a magnetic mud cleaning apparatus, the movable supporting box is arranged to be a hollow cavity, the cyclone dust collector penetrates through the upper wall of the movable supporting box and is arranged in the movable supporting box, an air inlet is formed in the side wall of the upper end ofthe cyclone dust collector, the negative pressure dust collection apparatus is arranged on the upper wall of the movable supporting box, the telescopic dust collection pipe is arranged at the input end of the negative pressure dust collection apparatus, the output end of the negative pressure dust collection apparatus is communicated with an air inlet of the cyclone dust collector, and the dust collecting cover is arranged at the end, away from the negative pressure dust collection apparatus, of the telescopic dust collection pipe. The invention belongs to the technical field of mining equipment, and particularly provides a metal dust collecting device which is high in practicability and safety, facilitates comprehensive collection of metal dust in the air, and facilitates machining in the cleaning apparatus.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and specifically refers to a metal dust collecting device for mechanical processing. Background technique [0002] Machining refers to the process of changing the shape, size or performance of the workpiece. This process is usually completed by mechanical processing equipment such as lathes; and when the mechanical processing equipment processes the workpiece, dust often occurs, and this kind of Most of the dust is powder composed of metal substances, which has certain harm to the human body. It is easy to cause a series of diseases in such a space for a long time, and a large amount of metal dust is easy to appear. If it is not collected in time, it is easy to damage the respiratory system of the staff. Cause injury and affect the health of personnel. Therefore, it is usually necessary to purify the air in the processing and production workshop to remove these dusts. There is a fi...

[0002] Machining refers to the process of changing the shape, size or performance of the workpiece. This process is usually completed by mechanical processing equipment such as lathes; and when the mechanical processing equipment processes the workpiece, dust often occurs, and this kind of Most of the dust is powder composed of metal substances, which is harmful to the human body. It is easy to cause a series of diseases in such a space for a long time, and a large amount of metal dust is easy to appear. If it is not collected in time, it is easy to damage the respiratory system of the staff. Cause injury and affect the health of personnel. Therefore, it is usually necessary to purify the air in the processing and production workshop to remove these dusts. There is a filter bag in the filter chamber, so that the gas containing dust passes through the filter bag, and the dust is separated from the gas under the filtering effect of the filter bag, and then the dust concentrated in the filter bag is collected by manually beating or shaking the filter bag. The dust on the surface falls off and is collected again. This method has a large amount of manual work, low efficiency, and the problem that some larger metal dusts cannot be recycled. In addition, metal dusts are highly sensitive to ignition. Most metal powders The minimum ignition energy is less than 10mJ

For ultra-fine metal powder, the minimum ignition energy is lower than 1mJ, and the fire sensitivity is strong and the risk is high. The existing metal dust collection device is inconvenient to clean, and the interior is easily blocked after long-term use, causing equipment damage.
