Abstract
The invention relates to a gate, in particular to a buffer gate, including a hydraulic cylinder, a fulcrum bearing, a shell, a fan-shaped shutter and a material flow regulating mechanism; the shell is internally provided with a cavity, both the upper and lower ends of the shell are provided with an opening, and the lower end of the shell is fixedly connected with the lower end of a storage hopper; the material flow regulating mechanism is arranged on the shell; the body of the hydraulic cylinder is hinged with the fulcrum bearing which is fixedly connected with the shell; the fan-shaped shutter has a groove-shaped structure in which a curved board is supported by a double-lug plate, the upper end of the fan-shaped shutter is hinged with the shell by a pin, the lower part of the shell is located in a groove of the fan-shaped shutter, and a piston rod of the hydraulic cylinder is hinged with the back side of the bottom of the fan-shaped shutter; the buffer gate is characterized in that: the front end of the fan-shaped shutter is fixedly connected with a surge hopper. The buffer gate can reduce the scouring abrasion of materials on a rubber belt for receiving materials, thus prolonging the service lift of the rubber belt. The buffer gate can be used for closing and opening the lower part of a bulk material storage hopper and especially applied to on an opening and closing device of an ore or coke storage hopper above a main rubber belt of a blast furnace.
Description
Technical field
The present invention relates to a kind of gate, be applied to the opening and closing of bulk material feed bin bottom, especially for the ore of blast furnace master adhesive tape top or the opening and closing device of coke feed bin.
Technical background
Blast furnace loose unpacked material coke and ore need repeatedly be had bad luck adhesive tape in transportation.When coke or ore when fixedly feed bin flow to the bottom adhesive tape through gate, can impact adhesive tape, have a strong impact on the life-span of adhesive tape.Particularly work as the operating mode (the material loading operating mode of blast furnace master adhesive tape) that a plurality of hoppers are arranged in juxtaposition along the adhesive tape transporting direction, except that first hopper, other hopper all can not be near excessively from adhesive tape, because in the time of must guaranteeing hopper blanking in front, back bunker gate and adhesive tape have enough spaces so that the material of heap fortune passes through on the adhesive tape.When this operating mode, bunker gate is higher from adhesive tape, and during blanking, materials flow is even more serious to washing away of adhesive tape.
Summary of the invention
The object of the present invention is to provide a kind of buffering type shutter, this buffering type shutter can reduce material to the washing away of the adhesive tape of material feeding, and prolongs the service life of adhesive tape.
To achieve these goals, technical scheme of the present invention is: buffering type shutter, and it comprises hydraulic actuating cylinder, supporting base, housing, fan-shaped flashboard, materials flow regulating mechanism; In the housing is cavity, and the upper and lower side of housing is open end, captives joint with the lower end of feed bin in the upper end of housing; Housing is provided with the materials flow regulating mechanism; The cylinder body and the supporting base of hydraulic actuating cylinder are hinged, and supporting base is captiveed joint with housing; Fan-shaped flashboard supports the groove shape structure of an arc for the ears plate, and the upper end of fan-shaped flashboard is hinged by bearing pin and housing, and lower part of frame is positioned at the groove of fan-shaped flashboard, and the bottom rear side of the piston rod of hydraulic actuating cylinder and fan-shaped flashboard is hinged; It is characterized in that: front end captive joint one buffering bucket of fan-shaped flashboard.
The invention has the beneficial effects as follows:
1, the great advantage of buffering type shutter is: when gate opening, buffering bucket can " dynamically prolong " gate slips the length of material base plate, makes the material landing to the bottom adhesive tape, reduces material to the washing away of adhesive tape, and prolongs the service life of adhesive tape;
2, when closing gate, buffering bucket and fan-shaped flashboard lift in the lump, make to have bigger space between gate and adhesive tape, and when other hopper blanking, the material on the adhesive tape also can pass through smoothly like this;
3, it is hinged that hydraulic actuating cylinder adopts middle part and supporting base, can effectively prolong the service life of hydraulic actuating cylinder.
