Intelligent and efficient dust collection workbench for grinding two ends of large workpiece

Abstract

An intelligent and efficient dust collection workbench for grinding the two ends of a large workpiece, comprising an operation area, a feeding area and a discharging area. The operation area is used for grinding the two ends of the workpiece; the feeding area and the discharging area are used for storing large work before and after grinding, respectively; a supporting platform for large workpieces is arranged in the middle of the workbench, and downward-concave L-shaped exhaust outlets are formed in the left side and the right side of the workbench; a L-shaped air outlet is connected with a dust collecting bin and used for collecting large-particle grinding dust; a rectification structure of an L-shaped air outlet is arranged in the workbench; the workbench is connected with a dust remover through an air pipe, and dusty gas is purified by the dust remover and then emptied; an infrared detector is arranged on the workbench, and intelligent control over air exhaust is achieved according to whether a worker is detected or not. The workbench can reduce the dust concentration of a respiratory zone of a worker to 0.4 mg / m3, and the dust collecting efficiency is 98.43%, so that the working environment is remarkably improved, and the occupational health of the worker is effectively guaranteed.

Description

technical field [0001] The invention relates to an intelligent and efficient dust-collecting workbench for grinding both ends of a large workpiece, belonging to the technical field of dust protection, and in particular to a dust-collecting workbench for grinding both ends of a large long workpiece with a hand-held grinding tool. Background technique [0002] Grinding has been widely used in rail transit manufacturing and other mechanical processing industries. The grinding process will generate a large amount of dust, which not only pollutes the environment, but also may cause pneumoconiosis when workers inhale a large amount of dust for a long time, seriously affecting the health of workers, and grinding aluminum and magnesium There is also a risk of explosion due to the dust generated when handling workpieces such as alloys. [0003] CN206241869U discloses a grinding table for magnesium-aluminum workpieces. The grinding table is provided with a dust collection device and a...

Problems solved by technology

[0004] When grinding small workpieces, the above-mentioned grinding workbench can be used to collect grinding dust, but in production practice, it is also necessary to grind both ends of large, long workpieces such as rail transit beams. Since the workpiece is long and only two ends of the workpiece are polished, small The workpiece grinding table is difficult to use
