Description

A kind of pulverizer

Technical field

The utility model is related to machinery equipment field, relate in particular to a kind of pulverizer.

Background technology

Pulverizer is widely used in all trades and professions such as food, chemical industry, mechanical processing, most common equipment when being crushing material One of.But existing pulverizer overall structure is more complicated, the material particular diameter after crushing is uneven, needs to carry out screening behaviour Make, screens out the larger material of the particle come and need to crush again, which needs to increase additional machinery equipment and work People wastes a lot of manpower and material resources, and increases production cost.

Such as Chinese patent notification number CN206286009U, a kind of pulverizer, including pulverizer theme are disclosed, crushes owner The top middle position of body is equipped with feeding equipment, and pulverizer is set inside the body live spindle, if being equipped in live spindle The outer edge surface of dry hammer body, hammer body is equipped with several broken blades, and fixing cutter is equipped on the both sides inner wall of pulverizer main body The bottom end left side of frame, pulverizer main body is equipped with discharge nozzle, and the left side of discharge nozzle is equipped with support leg, and the lower end of each support leg connects It is connected to damping spring, the bottom end of each damping spring is designed with support leg, and the patent is using the broken blade and stationary knife on hammer body Material is crushed, good crushing effect, sound panel reduces the noise generated when pulverizer work, and in feeding equipment Water spout is added in top, carries out humidification process to the dust overflowed from feeding equipment, it is therefore prevented that dust recycling is reduced to environment Pollution level.

For another example Chinese patent notification number CN204544295U, discloses a kind of micronizer, including pull filter plate, dials Expect blade, cooling chamber, meeting expects pipe, crush casing, finely divided disk and ultra-fine grinding disk, the crushing casing upper end is equipped with crushing electricity Machine crushes motor lower end and connects crushing main shaft by retarder, and crushing main shaft, which is equipped with, crushes thin disk and ultra-fine grinding disk, described A kind of ultrafine crusher, the material high-speed for being entered feed hopper using finely divided disk and ultra-fine grinding knife are crushed, and material is made to pass through The cutting and grinding of two kinds of different fineness, crushing is more thorough, improves crushing quality, and the limited use longevity for extending crushing knife Life, pull filter plate and feed back pipe effectively sieve the size of material, improve the quality of crushing, cooling chamber is crushing Material in the process is cooled down, and the temperature of processing materials is reduced, and ensures that the quality of material is not affected by high temperatures, in time to crushing Casing cools down, the limited service life for extending equipment.

But above-mentioned pulverizer existing defects in actual use：After crushing material after thickness detaches, separation Rough material out is direct and is crushed again into pulverizer together without the material of crushing, the rough material separated Grain size be less than without crushing material, when being ground, the rough material grinding effect separated is poor.

Invention content
