Description

Technical Field

[0001] The utility model belongs to the field of wear-resistant casting grinding devices, and in particular relates to a dust treatment device for grinding wear-resistant castings. Background Art

[0002] Wear-resistant castings are widely used in the manufacture of key parts of mechanical equipment due to their high hardness, high toughness, wear resistance, corrosion resistance and other advantages, so that they can maintain their shape and performance under conditions of friction, wear and impact. Wear-resistant castings need to be polished during processing, and a large amount of debris will be generated during the polishing process. In order to avoid the formation of dust that pollutes the environment, dust treatment equipment is often required for treatment.

[0003] At present, the existing dust treatment devices used for grinding wear-resistant castings are often large in size and installed together with the grinding platform. It is difficult to move the entire support platform. At the same time, the sizes and dimensions of wear-resistant castings are different. Once they are larger than the platform, the dust cover will lose its effect, resulting in dust and environmental pollution.

[0004] Therefore, in view of the problem that the existing dust treatment devices for grinding wear-resistant castings are often installed on a large grinding platform and are difficult to move, a dust treatment device for grinding wear-resistant castings is designed so that it can be carried around, and the dust suction head is installed on a handheld grinder, so that dust can be removed as the grinder moves, which is more flexible.
