Description
Technical Field
The utility model relates to a material classification equipment technical field, specifically speaking relates to a overgrate air separator for air current grader.
Background
The air classifier is a material classification device, the material moves to the classification area from the feeding port at the lower end of the classifier along with the ascending air flow at a high speed under the suction action of a fan, under the action of a strong centrifugal force generated by a centrifugal impeller rotating at a high speed, the coarse and fine materials are separated, the fine particles meeting the particle size requirement enter the upper end of the classification through a gap between two adjacent impeller sheets and then enter a cyclone separator or a dust remover to be collected, the speed disappears after the coarse particles carry part of the fine particles to collide with the wall, the coarse particles descend to the primary air port arranged above the feeding port along the cylinder wall, the coarse and fine particles are separated through the elutriation action of primary air, the fine particles ascend to the classification area to be classified for the second time, and the coarse particles are discharged from a coarse powder outlet. The air classifier is provided with an air inlet to classify materials twice, so that coarse and fine particles are not completely separated, and the yield is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a overgrate air separator for air classifier solves above technical problem.
In order to solve the above problems, the utility model adopts the following technical scheme:
a secondary air separation device for an airflow classifier comprises a shell fixedly arranged at the lower end of the cylinder wall of the airflow classifier and a plurality of ventilation pipes arranged along the periphery of the shell; the shell comprises an upper cover plate, a lower bottom plate and a coaming arranged between the upper cover plate and the lower bottom plate; the air outlet end of the ventilation pipe is fixedly assembled on the coaming and communicated with the inner cavity of the shell, and the air inlet end of the ventilation pipe is assembled with a secondary air regulating valve for controlling the air inlet amount.
Preferably: the secondary air regulating valve comprises a fixed air baffle fixedly assembled at the air inlet end of the ventilation pipe and a movable air baffle assembled outside the fixed air baffle, the fixed air baffle and the movable air baffle are in a fan blade shape and are connected through a bolt penetrating through the central parts of the fixed air baffle and the movable air baffle, and the movable air baffle can rotate along the bolt relative to the fixed air baffle and is locked and fixed through a fastening nut assembled on the bolt.
Has the advantages that: compared with the prior art, the utility model discloses the setting adopts the negative pressure air inlet mode to evenly distribute the wind through the inlet vent in to air classifier section of thick bamboo wall in the top of air classifier middlings export, has realized the tertiary of air classifier's secondary air inlet and material and has graded, makes the separation of coarse and fine particle more complete.
Drawings
Fig. 1 is a schematic view of the structure of the present invention assembled on the barrel wall of an airflow classifier.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Examples
Referring to fig. 1, the secondary air separation device for an airflow classifier according to the present embodiment includes a housing fixedly disposed at a lower end of a cylindrical wall 1 of the airflow classifier, and a plurality of ventilation pipes 2 disposed along a circumference of the housing. The housing comprises an upper cover plate 3 and a lower base plate 4 and a coaming 5 arranged between the upper cover plate 3 and the lower base plate 4. The air outlet end of the ventilation pipe 2 is fixedly assembled on the coaming 5 and communicated with the inner cavity of the shell, and the air inlet end is assembled with a secondary air regulating valve for controlling the air inlet amount.
The secondary air regulating valve comprises a fixed air baffle 6 fixedly assembled at the air inlet end of the ventilation pipe 2 and a movable air baffle 7 assembled at the outer side of the fixed air baffle 6, wherein the fixed air baffle 6 and the movable air baffle 7 are both in a leaf shape and are connected through a bolt 8 penetrating through the central parts of the fixed air baffle and the movable air baffle, and the movable air baffle 7 can rotate along the bolt 8 relative fixed air baffle 6 and is locked and fixed through a fastening nut 9 assembled on the bolt 8.
The utility model discloses install on the section of thick bamboo wall between the lower extreme of air current grading machine section of thick bamboo wall 1, pan feeding mouth and the middlings export. During the installation, evenly set up fresh air inlet 10 at the border of air classifier section of thick bamboo wall 1 at first (fresh air inlet 10 set up at upper cover plate 3 and lower plate 4 between, with the corresponding position of bounding wall 5), then will overgrate air separator weld on air classifier section of thick bamboo wall 1. When the wind shield is used, the fastening nut 9 is unscrewed, the movable wind shield 7 is rotated, and the gap between the movable wind shield 7 and the fixed wind shield 6 is adjusted to control the air intake.
The utility model discloses the setting is in the top of air current grading machine middlings export, adopts the negative pressure air inlet mode to evenly distribute the wind through the inlet vent in to air current grading machine section of thick bamboo wall, has realized the secondary air inlet of air current grading machine and the cubic of material is hierarchical, makes the separation of coarse and fine particle more complete.
The above is only the embodiment of the present invention, not so limit on the other hand through the patent scope of the present invention, all utilize the equivalent structure made in the specification and the attached drawings, directly or indirectly apply to other related technical fields, all with the same principle within the patent protection scope of the present invention.
