Abstract
The utility model provides a novel environmental-friendly blanking control valve which relates to a raw material blanking control device. The utility model comprises a main body and a valve body, wherein the valve body is sheathed on the main body; a pair of sash doors is arranged at a discharge port of the valve body; the sash doors are hinged on the valve body; hinged shafts of the sash doors are respectively provided with a gear; two gears are mutually engaged. The outside of the main body is provided with a driving device; an output push rod of the driving device is connected with the hinged shaft of one of the sash doors through a crank. The utility model can realize smooth discharge without the phenomenon of clamping material; the utility model has the advantages of compact structure, low production cost, easy control and favorable discharge effect.
Description
Technical field
The utility model relates to all kinds of source material delivery systems of industry such as metallurgy, mine, chemical industry, relates in particular to a kind of raw material falling control device.
Background technique
Existing discharge control apparatus has palate formula gate, fan gate etc.They all exist get stuck, shortcoming such as not environmental protection.For example, palate formula gate is made up of drive unit, gear train, arc fan door, hanger, axle, body etc.Palate formula gate is to drive arc fan door by drive unit, realizes that by gear train gate opening is with closed.Material often is stuck between arc fan door and the body in movement process, and along with the motion of fan door is pressed from both sides tighter and tighter, thereby cause device damage easily.Material is generally the dry type block, and the ambient contamination of equipment is big during blowing.
Summary of the invention
At above defective, the utility model provides a kind of unlatching that drives two fan fan doors by a drive unit with closed, the fan door of plate shaped bottom surface, the novel environment friendly blanking control valve that can not get stuck.
Novel environment friendly blanking control valve of the present utility model, comprise body, be sleeved on the valve body on the body, discharge port at valve body is provided with a door leaf-pairing door, this fan door is hinged on the valve body, and its hinging shaft respectively is provided with a gear, two gear engagement, be provided with a drive unit in body exterior, the output push rod of this drive unit connects the wherein hinging shaft of a fan fan door by crank.
Described drive unit comprises electro hydraulic gear and manual hydraulic device.
The inclined end face of described fan door is a platen surface.
Described body and valve body socket place are provided with sealing gasket.
Novel environment friendly blanking control valve of the present utility model, driver drives be formula fan door always, realizes opening and closing of gate by gear train, and the gap when opening between straight formula fan door and valve body is increasing, thereby realizes smooth discharging and do not have the phenomenon of getting stuck.The utility model compact structure, at the bottom of the cost of production, control easily, discharging is effective.
