Abstract

The utility model relates to a novel ultramicro vibration pulverizer which belongs to a vertical vibration pulverizer. The utility model is composed of an electrical motor, springs, eccentric blocks and an abrasive body, wherein, a shaft of the electrical motor is connected to the eccentric blocks through eccentric shaft coupling sections, and the inner part of the abrasive body is provided with abrasive rings. The utility model has the advantages of simple structure, small size, vibration resistance, homogeneous pulverization and high efficiency.

Description

Ultramicro-vibration pulverizer

The utility model belongs to a kind of vertical vibrating reducing mechanism.

At present, in the vertical vibrating disintegrating apparatus, West Germany, France, Japan adopts the vibration resistance motor, cost is very high, a kind of eccentric block directly is loaded on the common electrical arbor and produced in China, eccentric force directly acts on the motor shaft during work, the very fast heating of motor often burnt, and West Germany is loaded on eccentric block on the shatter-proof motor shaft, motor and bearing all adopt the large scale structure, the while casing, ring flange also adopts high-strength material, and motor bearings is because vibration causes bearing film to form, must use large-sized roller bearing and resistant to elevated temperatures lubricating oil, cost height, complex structure, adaptive capacity is poor.

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby a kind of antidetonation, simple in structure, ultra micro vibrating pulverizer that adaptive capacity is strong are provided.

The purpose of this utility model realizes with following mode:

Common electric machine is taked shock insulation and damping, and eccentric block directly is not contained on the motor shaft, and is contained on the bistrique, adopts centrifugal shaft coupling to be connected between bistrique axle and the motor, and vibration damping is to be finished by centrifugal shaft coupling and spring assembly.

Structure of the present utility model is as follows: pulverizer is made up of motor 1, base 2, spring 3, eccentric block 7, and base 2 is round casings, and the upper end edge circumference is evenly distributed spring 3.Wherein, spring 3 tops have bistrique seat 4, bistrique seat 4 lower ends are screwed motor 1, and motor shaft connects eccentric block 7 by centrifugal shaft coupling 5, has bistrique 9 on the bistrique seat 4, have bearing 8 on the locating shaft of bistrique 9, with eccentric block 7 sockets, bistrique 9 central authorities have the mill body 10, in have bull ring 12, mill body 10 is a cylindrical housings, and band mill in top covers 11.

Centrifugal shaft coupling 5 is to be made of slide block 6 and spring, is screwed with eccentric block 7, has been screwed spacer 14 on the bistrique 9 locating shaft end faces, also has pintle hook lock on the bistrique 9.

The utility model compared with prior art has following advantage:

Adopted centrifugal shaft coupling, reduced the startup load of motor, have damping, vibration isolation effect, the eccentric force that eccentric block is produced does not directly act on motor shaft, eccentric force passes on the bistrique by bearing and locating shaft, realize vibrations by spring action again, drive the mill body, the central point of mill body is made circular motion, bull ring is pulverized material because inertia can produce relative friction with mill body inwall, and the motor power demand reduces greatly, like this, overall structure is dwindled, the efficient height, has been reduced mechanical loss, mechanical life and improve greatly.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structure chart of the present utility model, also is an embodiment

Fig. 2 is the structure of eccentric block

In Fig. 1: 1, motor; 2, base; 3, spring; 4, the bistrique seat; 5, centrifugal shaft coupling; 6, slide block; 7, eccentric block; 8, bearing; 9, bistrique; 10, the mill body; 11, the mill lid; 12, bull ring; 13, pintle hook lock; 14, spacer.

Among the embodiment: spring 3 is connected between base 1 and the bistrique seat 4 by locating shaft up and down, the total six roots of sensation evenly distributes along circumference, and eccentric block 7 is enclosed within outside the bearing 8, be connected by screw with centrifugal shaft coupling, mill body 10 is divided into two up and down, and structure is identical, and locker is fixed on the bistrique 9, by depression bar and the fixing mill body topmost of platen, can be positioned by locating piece around the mill body, motor is selected the three phase squirrel cage motor for use, power 1.1KW.
