Technical Field
The utility model relates to an air duct splitter belongs to colliery underground air duct splitter technical field.
Background
The air duct splitter used under the coal mine is generally a soft air duct splitter and has the defects of poor pressure bearing capacity and easy damage. If the distance of the underground tunneling working face is long, the air supply distance is long, the air supply pressure of the local fan is large, the requirement of long-time safe air supply cannot be met, and the use of the high-efficiency contra-rotating fan is limited.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art exists not enough, and the technical problem that solve is for providing a dryer shunt that bearing capacity is strong.
In order to solve the technical problem, the utility model discloses a technical scheme be: a wind barrel flow divider comprises a shell, a bracket, a first ventilation opening, a second ventilation opening, a third ventilation opening, a partition plate, a limiting frame and a baffle plate;
the shell is supported by the bracket, the shell is in a trapezoid shape with a long front end and a short rear end, the first ventilation opening and the second ventilation opening are arranged up and down and are communicated with the end face of the front end of the shell, and the third ventilation opening is communicated with the end face of the rear end of the shell;
a partition board and two limiting frames are fixed in the shell to divide the inner space of the shell into three parts, the partition board is horizontally arranged, one end of the partition board is fixed on the inner side of the front end of the shell, the other end of the partition board is fixed with one end of each limiting frame, the other ends of the two limiting frames are respectively fixed on a top plate and a bottom plate of the shell, and each limiting frame is a quadrilateral frame;
the baffle plates which can alternately cover the hollow parts of the two limiting frames are hinged at the joint of the two limiting frames;
the limiting frame and the baffle are both made of hard materials.
Furthermore, the included angle of the two limiting frames is 90 degrees.
Furthermore, the limiting frame is formed by welding angle steel, and the baffle is an iron plate or a steel plate.
Compared with the prior art, the utility model following beneficial effect has.
The utility model has the advantages that the middle baffle plate automatically turns up and down under the action of the air supply pressure of the host machine or the spare machine, is communicated with the host machine ventilation air duct or the spare machine ventilation air duct, is not interfered with each other, has simple structure, flexible action and stable air flow; in addition, the limiting frame is welded by angle steel, and the baffle is an iron plate or a steel plate, so that the structure is firm, the bearing capacity is high, the air supply device is suitable for a long-distance air supply tunneling working surface, and the air supply device can be matched with a high-efficiency counter-rotating fan for use.
