Abstract

The utility model provides a 0.2 mm coal crusher, and solves the problems that the conventional crushing mill is not uniform in feeding, and not good in grinding effect. The adopted scheme is that the 0.2 mm coal crusher comprises a cylinder body provided with an opening at the lower end, wherein a feed opening is formed in the upper end surface of the cylinder body; a rotating shaft is fixed in the cylinder body in a rotating manner; the part, extending out of the upper end surface of the cylinder body, of the rotating shaft is connected with a motor through a transmission device; an eccentric shaft is mounted on the rotating shaft in a sliding and sleeving manner; an inner cone is mounted on the eccentric shaft in a sleeving manner through a bearing; an outer cone of which the inner cavity is a cone cavity matched with the inner cone is mounted on the inner wall of the cylinder body on the outer side of the inner cone; a clearance is reserved between the inner cavities of the inner cone and the outer cone; a stopping block in contact with the upper end surface of the eccentric shaft is mounted on the rotating shaft at the upper part of the eccentric shaft; a circular disc is fixed on the rotating shaft at the lower part of the inner cone; a spring is mounted on the rotating shaft between the circular disc and the inner cone in a sleeving manner; flinging pieces circumferentially distributed are mounted on the rotating shaft at the upper part of the stopping block. The 0.2 mm coal crusher can be used for crushing large particle materials, and can crush and grind the materials well, so that the materials can be uniformly crushed into the size of smaller than 0.2 mm.

Description

Point two millimeter coal disintegrating machine

Technical field

The utility model relates to breaker, particularly a kind of point two millimeter coal disintegrating machine.

Background technology

Existing a kind of coal breaker is vibromill, vibromill is to rely on powerful continuous impact to carry out abrasive dust, but because its amplitude is little, feed size can not be excessive, and crushing effect is bad, because its spring vibrates under very high frequency, be easy to fatigue, when especially spring surface has some spot or scar, can fracture because stress is concentrated, therefore the life-span of spring is very low, and its material thickness of grinding is inhomogeneous, the coal dust grinding does not reach the requirement of 0.2mm already, it is to adopt hand stock, artificial capping, the mode of the feeding of manually uncapping completes, automaticity is low, labour intensity is large, reinforced inhomogeneous.

Utility model content

For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of point two millimeter coal disintegrating machine, has effectively solved that existing pulverizing grinder charging is inhomogeneous, grinding effect is bad and the problem such as automaticity is low.

The scheme of its solution is, the cylindrical shell that comprises lower ending opening, there is charging aperture cylindrical shell upper surface, in cylindrical shell, center is rotated and is fixed with vertical rotating shaft, the rotating shaft that rotating shaft is partly stretched out cylindrical shell upper surface and stretched out upper surface connects motor through transmission device, in rotating shaft, slip cap is equipped with eccentric shaft, on eccentric shaft, through bearing holder (housing, cover), inner cone is housed, the Outer Taper that inner chamber is the cone cavity matching with inner cone is housed on the cylinder inboard wall of inner cone foreign side, gapped between inner cone and the inner chamber of Outer Taper, in the rotating shaft of eccentric shaft top, the block contacting with eccentric shaft upper surface is housed, in the rotating shaft of inner cone below, be fixed with disk, in rotating shaft between disk and inner cone, be set with spring, in the rotating shaft of said block top, the rejection tablet that is circle distribution is housed.

The utility model novel structure is unique, and stable performance can crushing large particle material, can be good at that material is carried out to fragmentation and rolls, and it is crushed to below 0.2mm uniformly, and can loading and unloading carries out continuously, and automaticity is high, time saving and energy saving.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

By Fig. 1, provided, the utility model comprises the cylindrical shell of lower ending opening, there is charging aperture 2 cylindrical shell 1 upper surface, the interior center of cylindrical shell 1 is rotated and is fixed with vertical rotating shaft 3, the rotating shaft that rotating shaft 3 parts are stretched out cylindrical shell 1 upper surface and stretched out upper surface is through transmission device connection motor 4, in rotating shaft 3, slip cap is equipped with eccentric shaft 5, on eccentric shaft 5, through bearing 6, be set with inner cone 7, on cylindrical shell 1 inwall of inner cone 7 foreign sides, the Outer Taper 8 that inner chamber is the cone cavity matching with inner cone 7 is housed, gapped between the inner chamber of inner cone 7 and Outer Taper 8, the block 9 contacting with eccentric shaft 5 upper surfaces is housed in the rotating shaft 3 of eccentric shaft 5 tops, in the rotating shaft 3 of inner cone 7 belows, be fixed with disk 10, in rotating shaft 3 between disk 10 and inner cone 7, be set with spring 11, in the rotating shaft 3 of said block 9 tops, the rejection tablet 13 that is circle distribution is housed.

Said cylindrical shell 1 lower ending opening place is connected to blanking hopper 15.

On said charging aperture 2, loading hopper 12 is housed.

In order to reach charging more uniformly, there is vibration bin 14 said loading hopper 12 tops.

Between said rotating shaft 3 and motor 4, through belt, belt pulley, connect.

The offset of said eccentric shaft 5 is 5 percent.

When the utility model is used, material is sent into cylindrical shell 1 uniformly through vibration bin 14, first there is rejection tablet 13 material scattering to be dropped on uniformly in the inner cone 7 and the gap between Outer Taper 8 of below, rotating shaft 3 drives eccentric shaft 5 to rotate, eccentric shaft 5 drives inner cone 7 constantly and the intracavity sidewall of Outer Taper 8 bumps against, material is rolled, it is crushed to below 0.2mm uniformly.
