A kind of low temperature freezing grinder

Abstract

The invention provides a low-temperature freezing grinding machine. The machine comprises a cooling mechanism and a grinding mechanism and further comprises a push rod mechanism and a material pipeline arranged in the cooling mechanism; a supporting rod which can movably extend and retract is disposed on the push rod mechanism; the material pipeline comprises a supporting rod branch way, a feedingbranch way and a discharging branch way which mutually communicate and of which one ends penetrate out of the cooling mechanism; the supporting rod branch way and the discharging branch way are arranged linearly; the feeding branch way faces upwards, an included angle is formed between the feeding branch way and the linear line; the supporting rod is movably inserted into the supporting rod branch way in a penetrating mode; one end of the discharging branch way is disposed over the grinding feeding end of the grinding mechanism; and the grinding discharging end of the grinding mechanism is provided with a collecting mechanism used for collecting ground materials. The grinding machine not only grinds the materials to be a fined state, and guarantees the absence of phenomenon of explosion during grinding.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a low-temperature freezing grinder. Background technique [0002] Grinding and dispersing equipment is the main equipment in the production process of powder materials. It is generally divided into two categories, one is grinding media with free movement (also called dispersion media), and the other is without grinding media. The equipment mainly relies on Wiping power for grinding and dispersing. The grinding and dispersing equipment commonly used in actual production without grinding media mostly grinds the materials not fine enough and the dispersion is not uniform enough. In the prior art, the material is first frozen with liquid nitrogen and then crushed, which not only makes the particles of the material finer, but also shortens the grinding time. However, in the freezing process, liquid nitrogen and materials need to be mixed together to achieve freezing. Not on...

AI Technical Summary

Problems solved by technology

If grinding or crushing is carried out in a closed space, it may cause an explosion in the closed space, which will not only affect the personal safety of the staff, but also affect the progress of production operations.
