Description
Technical field
The present invention relates to cutting equipment technical fields more particularly to one kind can screening type pulverizer.
Background technique
Pulverizer is primarily adapted for use in metallurgy, building materials, chemical industry, mine, expressway construction, water conservancy and hydropower, refractory material, steel
The grinding of the industries mineral products material such as iron is processed, by applying external force to material in crushing process, as pressure rolling, cutting, impact,
Grinding, makes crushing material become smaller, to adapt to the requirement of following process.
Although the crushing to bulk materials may be implemented in existing pulverizer, but dust is easy to produce in crushing process,
Aerial dust is diffused on the one hand to be easy that worker in people's suction body, is be easy to cause to generate serious occupational disease, another party
Face corresponds to some flammable materials, and the dust generated after crushing once meets with open fire, is easy to cause explosion, causes factory to generate serious
Production accident, endanger the life security of worker.
In addition, existing pulverizer crushing effect due to technical reason not can guarantee crush after particle scale size it is uniform
Property, the non-uniform material of these sizes makes following process effect that optimum level be not achieved, limits the quality of Related product
It is promoted.
Therefore, in order to solve the deficiency of existing pulverizer, needing to research and develop a kind of can both reduce dust during crushing material
Phenomenon is diffused, and pulverized particles of uniform size can be provided, and the Novel mill that structure is relatively simple.
Summary of the invention
The problem to be solved in the present invention is to provide one kind can screening type pulverizer.
To solve the above problems, the present invention adopts the following technical scheme: one kind can screening type pulverizer, including outer housing,
Grinding device and several screening boxes, outer housing are hollow structure, and feed hopper, setting below feed hopper are provided at the top of outer housing
There is a grinding device, the motor form that grinding device is rotated by two crushing shafts to roller and driving crushing shaft is set among outer housing
Be equipped with several can draw and insert-type screening box, screening box bottom is provided with the sieve with different pore size size, crushes motor spindle and set
It is equipped with and the blower of downward adsorption capacity is provided.
Further, motor drives the second gear on adjacent crushing shaft reversely to turn by first gear rotation thereon
Dynamic, second gear drives the third gear on another crushing shaft to rotate backward by rotation.
Specifically, the close Disintegrating knife group of arrangement is provided on above-mentioned crushing shaft, the Disintegrating knife on different crushing shafts
Group is staggered.
Further, outer housing front is provided with several openings for being screened for box insertion, and opening is in internal left and right two
Bottom position is provided with the fin to play a supportive role to the screening box being inserted into.
Further, outer housing is provided with powder below lowermost layer screening box and accepts layer, and it is funnel that powder, which accepts layer,
Shape, powder accept the opening that is provided centrally with of layer, and opening is connect by pipeline with blower.
Further, outer housing is internally provided with concussion generator, shakes generator vibration frequency 100KHz.
The invention has the beneficial effects that: pulverizer is internally provided with screening box can be big according to particle to the material of crushing
Small to be screened, excessive for particle can re-start crushing, while crushing motor spindle and being provided with blower, can adsorb powder
The dust generated during broken reduces influence of the dust to environment and worker's body.
Detailed description of the invention
Attached drawing 1 be in embodiment 1 it is a kind of can screening type pulverizer front view；
Attached drawing 2 be in embodiment 1 it is a kind of can screening type pulverizer along face A-A cross-sectional view；
Attached drawing 3 is that one kind can screening type pulverizer partial sectional view in embodiment 1.
Specific embodiment
Embodiment 1: referring to figs. 1 to Fig. 3, one kind can screening type pulverizer, including outer housing 1, grinding device 10 and several
A screening box 3,4, outer housing 1 are hollow structure, are provided with feed hopper 2 at the top of outer housing 1, crushing is provided with below feed hopper 2
Device 10, grinding device 10 are made of the motor 11 that two crushing shafts to roller and driving crushing shaft rotate, set among outer housing 1
Be equipped with several can draw and insert-type screening box 3,4,3,4 bottom of screening box is provided with the sieve 15,16 with different pore size size, institute
It states and crushes motor spindle and be provided with the blower 5 of downward adsorption capacity is provided.
Further, motor 11 drives the second gear on adjacent crushing shaft reversely to turn by first gear rotation thereon
Dynamic, second gear is rotated backward by the third gear on another crushing shaft of rotation drive, two crushing shafts rotation direction phase each other
It is counter that material is made to be pullled power by what is drawn close among two crushing shafts, it is ensured that material will not touch winged in crushing process.
Specifically, the close Disintegrating knife group of arrangement is provided on crushing shaft in order to improve the crushing effect of material, it is different
Disintegrating knife group on crushing shaft is staggered, crushing shaft diametral distance is moderate allow Disintegrating knife group close to each other without
It can collide when rotated.
Further, 1 front of outer housing is provided with several openings for being screened for the insertion of box 3,4, and opening is in inside left and right
Two bottom positions are provided with the fin 7 to play a supportive role to the screening box being inserted into, screening box located above in pulverizer
Internal screen aperture be greater than underlying screening box mesh size, may insure the crushing of variable grain scale in this way
Particle is efficiently separated.
Further, it because there are part superfines particle, is not easy to be screened box and screens, therefore in outer housing 1
In lowermost layer screening box below be provided with powder accept layer 6, powder accept layer 6 be funnel-form, powder accept layer 6 center
It is provided with opening, opening is connect with blower 5 by pipeline, provides powerful adsorption capacity by blower 5 and to produce in crushing process
The injury that raw dust particles are adsorbed downwards and reduce dust to body.
Further, in order to improve screening box screening effect, outer enclosure interior is provided with concussion generator 12, concussion hair
