Abstract

The invention provides a moving cutter shaft assembly of a screen-free caustic soda pulverizer and the screen-free caustic soda pulverizer. According to the screen-free caustic soda pulverizer, an inner screen structure of an existing pulverizer is omitted, the defects that the existing pulverizer adopts a screen, abrasion is caused quite easily, and the screen can be squeezed and damaged by raw materials operating in a machine body are overcome, energy is saved, the production cost is lowered, and the environment is not polluted. The moving cutter shaft assembly comprises a moving cutter shaft connected with a pulverizer power device; a plurality of cutter holders are spirally distributed on the moving cutter shaft in the axial direction; each cutter holder is detachably connected with a cutter; and the cutters include the straight cutters and the bent cutters, and the straight cutters and the bent cutters are arranged alternately. The screen-free caustic soda pulverizer comprises more than one pulverizing device; each pulverizing device comprises a shell and one moving cutter shaft assembly, wherein the two ends of the moving cutter shaft are mounted on the shell through bearings, and the shell is provided with a material inlet and a material outlet; and the material outlet of the first pulverizing device is connected with the material inlet of another pulverizing device.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a moving knife shaft assembly of a caustic soda pulverizer without a screen and a caustic soda pulverizer without a screen, which are suitable for chemical enterprises to pulverize caustic soda and other chemical raw materials that are easy to agglomerate Crushing can also be used in the crushing of wet materials in other industries and in the technical field of chemical raw material crushing. Background technique [0002] Caustic soda is a white opaque solid at room temperature, in the form of blocks, flakes, rods, granules, etc. It has strong hygroscopicity, is easy to deliquesce, is brittle, and is easily crushed. At present, high-speed universal pulverizers and hammer mills are commonly used in the market for pulverization. These two types of machines have screens, which are easy to wear when pulverized, and are also easily crushed by the rotating materials in the machine. There are many fault...
