Abstract
The utility model relates to a hydraulic turn-off gate, which comprises a frame, a plurality of side hydraulic cylinders which are arranged at the side of the frame, push rods connected with piston rods of the hydraulic cylinders, side gates arranged on the push rods, end surface hydraulic cylinders arranged on the end surfaces of the frame, connecting rods driven by the end surface hydraulic cylinders, end gates which are driven by the connecting rods and work at an inclined angle, and a high-temperature concrete heat insulation layer which is arranged at the inner side of the frame. The hydraulic turn-off gate is convenient to use and maintain, is simple to operate, has tight closing and reliable sealing, improves the availability of a boiler, ensures the heat efficiency of the boiler, has fire resistance and abrasion resistance, can be widely used in a slag removal system of a coal-fired power plant.
Description
Technical field the present invention relates to a kind of hydraulic pressure shutoff door, can be widely used in the coal-burning power plant and remove in the slag system.
Background technology is present, existing shutoff door, and its end door is vertical placement when boiler operatiopn, big or when bulk is arranged when the dragveyer quantity of slag like this, meeting is with end Men Lakai, but the quantity of slag just often, and end Men Buhui goes back to the upright position, will be not closed completely, it is serious to leak out, and influences boiler thermal output.
Summary of the invention the object of the present invention is to provide a kind of O﹠M convenient, simple to operate, close tight, sealing is reliable, improve boiler equipment availability factor, guarantee boiler thermal output, the hydraulic pressure shutoff door of fire-resistant, erosion resistant.
In order to achieve the above object, hydraulic pressure shutoff door of the present invention, comprise framework, be installed in several side hydraulic cylinders on the frame facet, the push rod that links to each other with hydraulic cylinder piston rod is installed in the side door on the push rod, be installed in the end face hydraulic cylinder on the framework end face, by the connecting rod of end face Driven by Hydraulic Cylinder, by the end door that is the work of certain angle of inclination that connecting rod drives, the inboard high temperature concrete thermal insulation layer that is provided with of framework.
Hydraulic pressure shutoff door of the present invention, said end door, its angle of inclination is 70 °～80 °.
Hydraulic pressure shutoff door of the present invention, its operation principle is: when dragveyer normally moved, shutoff door was opening; When dragveyer overhauls, close shutoff door by hydraulic cylinder.
Hydraulic pressure shutoff door of the present invention, its effect is: the hydraulic pressure shutoff door is installed in boiler slag down-hole portion, enables when the short-duration failure maintenance appears in dragveyer, when the dragveyer operate as normal, inserts maintenance boiler bottom sealing in the water by shutoff door; Need haul out when maintenance when short trouble appears in dragveyer,, can make boiler inside and outside isolated as long as close shutoff door.Slag accumulates on the shutoff door when dragveyer overhauls, and reaches the not purpose of shutdown maintenance dragveyer, avoids occurring because of the furnace bottom equipment fault accident of shutdown.In finite time, slag removal equipment is rushed to repair temporarily.
Hydraulic pressure shutoff door of the present invention uses, easy to maintenance, simple to operate, because shutdown maintenance dragveyer has not improved boiler equipment availability factor.
Hydraulic pressure shutoff door of the present invention, its end door is certain number of degrees that tilt, and big slag is drawn back when coming, and big slag will go back to the position of primary dip in the past, has improved the thermal efficiency of boiler like this, and the end door has just guaranteed that also the shutoff door sealing is reliable.
Hydraulic pressure shutoff door of the present invention can guarantee that shutoff door in off position down, does not leak lime-ash, do not leak out.
Hydraulic pressure shutoff door of the present invention, slag enters submerged slag conveyor through slag bucket, shutoff door, because the water seal characteristic of shutoff door can guarantee boiler thermal output, keeps the sanitation and hygiene of boiler room.
Hydraulic pressure shutoff door of the present invention, the inboard lining of framework is established high temperature concrete thermal insulation layer, fire-resistant, erosion resistant.
In sum, hydraulic pressure shutoff door of the present invention, O﹠M is convenient, and is simple to operate, closes tightly, and sealing is reliable, improves boiler equipment availability factor, guarantees boiler thermal output, fire-resistant, erosion resistant.
Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view among Fig. 1;
Fig. 3 is the left view among Fig. 1.
The specific embodiment is in Fig. 1～Fig. 3, hydraulic pressure shutoff door of the present invention, comprise framework 1, be installed in several side hydraulic cylinders 2 on the frame facet, the push rod 3 that links to each other with hydraulic cylinder piston rod is installed in the side door 4 on the push rod, be installed in the end face hydraulic cylinder 5 on the framework end face, by the connecting rod 6 of end face Driven by Hydraulic Cylinder, by the end door 7 that is the work of certain angle of inclination that connecting rod drives, the inboard high temperature concrete thermal insulation layer 8 that is provided with of framework.
Hydraulic pressure shutoff door of the present invention, said end door 7, its angle of inclination a are 70 °～80 °.
