Described motor is a variable-frequency motor, is connected with flat key with rear-end of spindle.

Described pulverizing knife rest is being pulverized on the knife rest circumferencial direction, the four row's knives that are symmetrically distributed, and every row is by staggered spaced apart four knife, has 16 knife formed; The end surface shape of knife, on one side it is a cutting edge, another side is the plane, because crushing knife tool is to be symmetrical structure with the center line, crushing knife tool can reverse end for end to install, and can realize cutting and pulverize and hammer into shape the conversion of pulverizing.

Be equipped with on the described main shaft between two sealing rings, two sealing rings certain interval is arranged, protecgulum downside at gap location is drilled with aperture, aperture one side and sleeve downside one air duct UNICOM, the air duct downside is drilled with two holes, the hole that muffler, the left side are equipped with in the hole on the right is equipped with snap joint and is inserted compressed air, make that there is certain pressure in the gap between two sealing rings, powder material can not be leaked to the rolling bearing position, prolong the service life of bearing.

The invention has the beneficial effects as follows:

1, high-speed and high-efficiency pulverizer production efficiency height of the present invention can reach 4500 rev/mins after frequency control;

2, the output of material input and material is convenient;

3, the feed bin internal structure is simple, and dismounting maintenance and cleaning are convenient;

4, crushing knife tool can realize that cutting is pulverized and two kinds of function conversion are pulverized in hammering;

5, Du Te pressurized seal mechanism solves the problem that the common poor sealing that exists of pulverizer causes damage of bearings.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present invention is described further.

See also shown in Fig. 1,2, the present invention includes casing 1, drive disk assembly and crushing knife tool three parts constitutes, casing 1 is cylinder and rectangular welding body, bottom half is empty, unload six ring-like nuts 3 and can take off the bottom that positive door closure 2. semicircular screen cloth 10 assemblies are positioned at pulverizing knife rest 4, be installed in the lower half circle position of casing by six banking pins 24, can change the screen cloth of different meshes according to the powder size requirements.Overall construction design is convenient to change the cleaning of cutter and screen cloth and feed bin inside.

One sleeve 22 connects protecgulum 12 by six hexagon socket head cap screws 21 and is fixed on the casing 1, and bonnet 18 is fixedlyed connected with sleeve 22 by six hexagon socket head cap screws 16; Main shaft 9 is installed in the sleeve 22, two sealing rings 23 that both forward and reverse directions is relative are equipped with at main shaft 9 middle parts, sealing ring 23 outer rings and protecgulum 12 tight fits, main shaft 9 postmedians are equipped with two rolling bearings 15, two rolling bearings 15 and sleeve 22 internal diameter tight fits, and axially fasten with packing ring 17 and locking nut 19, spacer 13 of suit on the main shaft 9 between two rolling bearings 15, main shaft 9 leading sections are pegged graft with pulverizing knife rest 4 endoporus, two straight pins in main shaft 9 front end ends 8 are pegged graft with the pin-and-hole of pulverizing on the knife rest 4 middle part connecting portions, so that transmit moment of torsion.

Pulverize the four row's knives that are symmetrically distributed on knife rest 4 circumferencial directions, every row is by interlocking spaced apart four knife, having 16 forms knife, the section configuration of knife is seen the B-B cutaway view of Fig. 3, on one side it is a cutting edge, another side is the plane, because crushing knife tool is to be symmetrical structure with the center line, therefore install by the tune of crushing knife tool, can realize the cutting of material is pulverized and the conversion of hammer between pulverizing, promptly select grinding mode according to the character of material.Pulverize knife rest 4 front end faces and be fixed tightly on the little axle 7 by gland 5 usefulness hex bolts 6, little axle 7 and main shaft 9 tight fits are integrally welded.

Be connected with variable-frequency motor with flat key 20 in main shaft 9 rear ends, beater grinder is worked under the rotation at a high speed 4000 rev/mins (variable ratio frequency changer speed governing) usually, and material is formed a cylindrical pulverization face, and the present invention has efficient feature.

Sealing ring 23 between main shaft 9 and protecgulum 12 is designed to unique hermetic seal structure, between two sealing rings, can insert compressed air, compressed-air actuated pressure makes the certain pressure of maintenance between two sealing rings, make the powder material at position, powder storehouse can not enter into bearing portion, strengthened the sealing effectiveness of sealing ring, prolong the service life of bearing, muffler 14 has been installed on the air duct of lower cartridge, played the effect that gas reduces noise of discharging that makes.
