Description

A kind of self-rotating sawdust separator

Technical field

The utility model relates to coal dust application, particularly relates to a kind of self-rotating sawdust separator.

Background technology

Coal dust is as a kind of powdered fuel, with solid-state coal facies ratio, when burning, greatly increases with the contact-making surface of air, can make to burn more abundant, and efficiency of combustion is higher, is widely used in power plant field.Coal dust has some wood chips, wooden unit and other fiber-like impurity and enters in finished product coal dust in preparation, not only can reduce the calorific value of coal dust, also can when coal dust is carried, cause the obstruction of pipeline, has a strong impact on continuous production.So, need to after pulverized coal preparation, to coal dust, filter, clear out of the impurity such as wood chip that mix in coal dust.

Self-rotating sawdust separator is current widely used a kind of pulverized-coal filtering equipment, the rotation type coal dust wood scraps separator using at present mainly comprises: housing, main shaft, blade, sieve, charging aperture and discharging opening form, coal dust enters housing from charging aperture, effect due to coal dust deadweight, drive blade rotary, coal dust is trickled down uniformly on screen cloth, and screen cloth falls the contaminant filters such as wood chip in coal dust, and coal dust is discharged from discharging opening.But the defect of this design is: screen cloth is easily piled up, putty, needs regularly to shut down the wood chip on cleaning screen cloth, and waste of manpower cost not only has also reduced the filter efficiency of coal dust.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of self-rotating sawdust separator, can avoid wood chip to be deposited on screen cloth, has improved screening effeciency, has reduced human cost.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of self-rotating sawdust separator is provided, comprise: housing, charging aperture, discharge, screen cloth, main shaft and blade, described charging aperture is arranged at the top of housing, eccentric setting, discharge is arranged at the bottom of housing, the central shaft of housing arranges main shaft, the lower end of main shaft is provided with blade, the below of blade arranges screen cloth, housing is stretched out in the upper end of main shaft, the upper end of main shaft is provided with handwheel, described self-rotating sawdust separator also comprises: vibrating motor, wood chip collecting vessel, wood chip outlet and chip removal mouth, described vibrating motor and wood chip collecting vessel are separately positioned on outer two the symmetrical sides of housing, vibrating motor drives screen cloth vibration, between wood chip collecting vessel and housing, by wood chip, export and communicate, one end of described screen cloth extend in wood chip collecting vessel through wood chip outlet, the bottom of wood chip collecting vessel arranges chip removal mouth.

Preferably, the angle between described screen cloth and horizontal plane is 3-10 degree.

Preferably, described screen cloth near one end of vibrating motor higher than the one end near wood chip collecting vessel.

Preferably, the material of described screen cloth is stainless steel.

The beneficial effects of the utility model are: the utility model (1) has avoided wood chip to be deposited on screen cloth, has improved screening effeciency; (2) reduce the manually-operated time, saved human cost.

Accompanying drawing explanation

Fig. 1 is the cutaway view of a kind of self-rotating sawdust separator one preferred embodiment of the utility model;

Fig. 2 be shown in a kind of top view of self-rotating sawdust separator;

In accompanying drawing, the mark of each parts is as follows: 1, housing, 2, charging aperture, 3, discharge, 4, screen cloth, 5, vibrating motor, 6, main shaft, 7, blade, 8, wood chip collecting vessel, 9, wood chip outlet, 10, chip removal mouth, 11, handwheel.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:

A kind of self-rotating sawdust separator, comprise: housing 1, charging aperture 2, discharge 3, screen cloth 4, main shaft 6 and blade 7, described charging aperture 2 is arranged at the top of housing 1, eccentric setting, discharge 3 is arranged at the bottom of housing 1, the central shaft of housing 1 arranges main shaft 6, the lower end of main shaft 6 is provided with blade 7, the below of blade 7 arranges screen cloth 4, housing 1 is stretched out in the upper end of main shaft 6, the upper end of main shaft 6 is provided with handwheel 11, described self-rotating sawdust separator also comprises: vibrating motor 5, wood chip collecting vessel 8, wood chip outlet 9 and chip removal mouth 10, described vibrating motor 5 is separately positioned on outer two the symmetrical sides of housing 1 with wood chip collecting vessel 8, vibrating motor 5 drives screen cloth 4 vibrations, between wood chip collecting vessel 8 and housing 1, by wood chip, exporting 9 communicates, one end of described screen cloth 4 extend in wood chip collecting vessel 8 through wood chip outlet 9, the bottom of wood chip collecting vessel 8 arranges chip removal mouth 10.

Operation principle of the present utility model is: coal dust falls in housing 1 from charging aperture 2, the deadweight band moving vane 7 of coal dust rotates, coal dust can be trickled down comparatively equably on screen cloth 4, vibrating motor 5 drives screen cloth 4 vibrations, impurity in coal dust has been left on screen cloth 4, and along with the shake of screen cloth 4, wood chip impurity slowly moves in wood chip collecting vessel 8, finally, wood chip is discharged from chip removal mouth 10, and coal dust is discharged from discharge 3, realized the separated of coal dust and wood chip and other impurity, good filtration effect, do not need Artificial Control screen cloth to discharge wood chip, improved filter efficiency, reduced human cost.

Acting as of main shaft upper end handwheel 11: when the inlet of coal dust too much causes the rotation of blade 7 to have some setbacks, shake handwheel 11, make the rotation of blade 7 more smooth and easy.

Further, angle between described screen cloth 4 and horizontal plane is 3-10 degree, described screen cloth 4 near one end of vibrating motor 5 higher than the one end near wood chip collecting vessel 8, vibration due to screen cloth 4, the wood chip filtering out on screen cloth 4 can fall in wood chip collecting vessel 8 along with shake, prevented that wood chip from piling up on screen cloth 4, caused and block up.

Further, the material of described screen cloth 4 is stainless steel, and stainless steel surfaces is comparatively smooth, can farthest avoid coal dust to be adsorbed on screen cloth 4.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
