Description

Air current grader

Technical Field

The utility model relates to an air classifier.

Background

The air classifier is an air classifying device, and the classifier, a cyclone separator, a dust remover and an induced draft fan form a set of classifying system. The material moves to the classification area from the feeding port at the lower end of the classifier along with ascending air flow at high speed under the action of suction force of a fan, under the action of strong centrifugal force generated by a classification turbine rotating at high speed, the thick and thin materials are separated, the fine particles meeting the particle size requirement enter a cyclone separator or a dust remover through the blade gaps of the classification wheel for collection, the speed of the fine particles carried by the coarse particles disappears after the fine particles collide with the wall, the coarse particles descend to the secondary air port along the cylinder wall, the coarse and thin particles are separated through the strong elutriation effect of secondary air, the fine particles ascend to the classification area for secondary classification, and the coarse particles descend to the discharge port for discharge.

The material can appear the phenomenon of agglomerating when actual production, and difficult dispersion causes that classifying wheel department often has the large granule material to spill over, makes the qualification rate of product descend, simultaneously because the agglomeration of material can cause the work load of draught fan higher, causes the energy consumption to increase.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an air current grader to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an air classifier, includes the grader body, the material passageway pipe in the grader is the toper structure, and the inside of material passageway pipe is fixed with many dead levers, every all be fixed with a plurality of crushed aggregates piece on the dead lever.

As a further aspect of the present invention: the crushed material block is of a hemispherical structure.

As a further aspect of the present invention: the material crushing block is made of stainless steel.

As a further aspect of the present invention: the classifier body is internally provided with a classifying wheel, the classifying wheel is driven by a driving motor arranged at one side of the classifier body to operate, the classifier body is provided with a fine powder outlet at the position corresponding to the classifying wheel, the lower part of the classifier body is provided with a raw material inlet and a secondary air inlet in the tangential direction of the classifier body, and the bottom of the classifier body is provided with a coarse powder outlet.

As a further aspect of the present invention: the driving motor is electrically connected with an external power supply and the control switch.

Compared with the prior art, the beneficial effects of the utility model are that: the material can be broken up in the rising process through the crushed aggregates piece of design, and the material can realize accurate separation reaching hierarchical wheel department for hierarchical qualification rate promotes 95% from 80%, simultaneously owing to reduced the power of draught fan, the effect of economizing on electricity of this application is showing more.

In the figure: 1-driving motor, 2-grading wheel, 3-fine powder outlet, 4-secondary air inlet, 5-raw material inlet, 6-coarse powder outlet, 7-material channel pipe, 8-fixing rod and 9-crushed material block.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Please refer to fig. 1-2, in the embodiment of the utility model, an air classifier, including the grader body, material passageway pipe 7 in the grader is the toper structure, and the inside of material passageway pipe 7 is fixed with many dead levers 8, every all be fixed with a plurality of crushed aggregates piece 9 on the dead lever 8, crushed aggregates piece 9 can be located dead lever 8's upper and lower surface separately, and when the material was in the motion of material passageway pipe 7, crushed aggregates piece 9 can be broken up the material of conglomeration gathering, the better hierarchical processing of being convenient for.

Further, the material crushing block 9 is of a hemispherical structure and is made of stainless steel.

Example 2

Referring to fig. 1, the embodiment of the present invention is to further explain the structure of the classifier body, specifically, the classifier body is internally provided with a classifying wheel 2, the classifying wheel 2 is driven by a driving motor 1 installed at one side of the classifier body, the classifier body is provided with a fine powder outlet 3 at a position corresponding to the classifying wheel 2, the lower part of the classifier body is provided with a raw material inlet 5 and a secondary air inlet 4 in the tangential direction of the classifier body, and the bottom of the classifier body is provided with a coarse powder outlet 6.

The utility model discloses a theory of operation is: the material enters into the grader from raw materials entry 5 internally, the phenomenon of agglomerating can appear in the material when actual production, be difficult for the dispersion, cause that classifying wheel 2 department often has the large granule material to spill over, but because the design of bits of broken glass piece 9 in this application, can make the material in the motion process from bottom to top, can collide with crushed aggregates piece 9, the material of agglomerating is smashed, later reach classifying wheel 2 department and can realize accurate separation, make hierarchical qualification rate promote to 95% from 80%, simultaneously owing to reduced the power of draught fan, the economize on electricity effect of this application is more showing.
