Description of drawings
Fig. 1 is the utility model vertical view.
Fig. 2 is the utility model bottom framework part front view.
Fig. 3 is the utility model left view.
Each parts label is as follows in the accompanying drawing:
Bottom framework 1, grid 2, pressurizing unit 3 drives hydraulic cylinder 4, hydraulic cylinder leg 5, casing 6;
Pressurizing unit 3 comprises: extrusion head 3-1, extruding casing 3-2, rolling wheels 3-3, guide rail 3-4, connecting rod 3-5;
The specific embodiment
The utility model structure comprises:
Bottom framework 1, the frame structure that connects into by shaped steel and by upright supports; Bottom framework 1 can be formed by H shaped steel and channel-section steel assembly welding, and it is the basic platform of hydraulic pressure shutoff door device, and its quality directly influences the performance of hydraulic pressure shutoff door device.
Grid 2 is installed on above the bottom framework 1; Grid 2 is made up of high temperature resistant steel plate, with the high temperature resistant thick walled steel tube of guide rail 3-4 of pressurizing unit 3 and support I-steel one and reinstate Bolt Connection on bottom framework 1.Taking casing 6 side plates apart when grid 2, when the high temperature resistant thick walled steel tube of guide rail 3-4 need be changed gets final product.Spacing between the grid designs according to the size of coal coking.
Pressurizing unit 3, and the guide rail 3-4 on being fixed in the bottom framework 1 and connecting rod 3-5 that is connected pressurizing unit and driving hydraulic cylinder forms by a pair of extrusion head 3-1 that does relatively reciprocating motion, extruding casing 3-2, rolling wheels 3-3; Extrusion head 3-1 connects by bearing pin with extruding casing 3-2, in extrusion head 3-1, extruding casing 3-2 bottom rolling wheels 3-3 is installed; At the extrusion head 3-1 of pressurizing unit 3 end face is tooth-shape structure, is provided with a plurality of risers above the extrusion head 3-1, is used for big clinker is choked and cuts off.The pressurizing unit 3 of both sides respectively drives hydraulic cylinders 4 by two and drives and control.The guide rail 3-4 of pressurizing unit 3 is high temperature resistant thick walled steel tube, and the bottom has I-steel to support.Make its flexural deformation in the time of can avoiding big clinker to fall like this to steel pipe.
Extrusion head 3-1 is formed by the casting of high-quality heat resisting steel, and extruding casing 3-2 is welded by heat-resisting steel sheet and plate.This structure is convenient to the replacing after the extrusion head wearing and tearing, has reduced operating cost.The tooth-shape structure of extrusion head 3-1 end face, hot slag that energy will be bigger or the cinder that has cooled off fully squeeze and are broken into than granule, fall on the slag extractor steel band by grid.Extrusion head 3-1 end face can be deep in the middle of the grid, and the cinder that can will be stuck between grid and the I-steel squeezes broken.Each extrusion head 3-1 is controlled by two hydraulic cylinders, guarantees the steady and synchronous operation of exerting oneself.Rolling wheels 3-3 is made by the Wear-resistant, high-temperature resistant material, and the effect of playing the support extrusion head and reducing friction can prevent extrusion head sideslip and bite with guide groove, having reduced the motion wearing and tearing, guarantees steady, the operation fast of extrusion head 3-1.
Drive hydraulic cylinder 4, be installed on the hydraulic cylinder leg 5, its plunger connects with the connecting rod 3-5 of pressurizing unit 3; Driving hydraulic cylinder 4 is power sources that the hydraulic pressure shutoff door is put, and can provide enough big pressure to squeeze the broken slag that falls.
Hydraulic cylinder leg 5, the frame structure of getting up by channel-section steel and plate assembly welding and by upright supports; , be used for the support drive hydraulic cylinder, the distortion that produces when having enough rigidity to prevent the oil cylinder frequent operation.
Casing 6 is enclosed to connect by steel plate and forms, between boiler transition slag well and hydraulic pressure shutoff door device, with the space that forms sealing.Casing 6 effectively couples together transition slag well and hydraulic pressure shutoff door device, forms a totally enclosed overall structure.Open box side and can change extrusion head and grid fast.Tank ends is provided with peep hole, is convenient to observe at any time the fall situation of slag size and extrusion head disintegrating slag of boiler.
Be provided with spray cooling system below pressurizing unit 3 guide rail 3-4, spray cooling system is made up of some shower nozzles, connecting line and valve piece.Can the slag under the big quantity of slag operating mode be cooled off.
In casing 6 both sides shooting and monitoring system is installed.The operations staff can observe slag at central station of floating dock, in time starts pressurizing unit and squeeze it broken when big cinder drops on the grid.
The utility model can be constituted jointly by many groups grid 2 and many group pressurizing units 3 and corresponding driving hydraulic cylinder 4.Fall on the grid 2 when big slag, the extrusion head 3-1 that can start the relevant position carries out independent fragmentation, saves energy, increases work efficiency.
Hydraulic pressure shutoff door device adopts the electrical control hydraulic-driven, and door has the open and close two states.Observe when having big slag muck to amass on the grid by shooting and monitoring system, the extrusion head that starts correspondent section carries out fragmentation.
Hydraulic pressure shutoff door device also is provided with control mode on the spot except that above-mentioned central station of floating dock control.
The big clinker of discharging in the boiler at first is blocked on the grid and obtains pre-cooledly, observes the slag situation by shooting and monitoring system, and when big clinker, what the extrusion head of splitting by control moved horizontally squeezes it broken.
When the follow-up equipment fault maybe needs to overhaul, under the situation of the normal operation that does not influence boiler, can start pressurizing unit furnace bottom is closed.Can be by to opening it after maintenance finishes, avoid the moment quantity of slag excessive follow-up system to be caused damage.
