Field.
Background technology
Sintering machine is to be sintered the mixture of a certain proportion of miberal powder, flux and bulk cargo, become to supply blast furnace with containing
The equipment of the high sinter of iron, there are mainly two types of patterns, i.e. step-by-step type sintering machine and continuous pallettype sintering machine for sintering machine.Existing burning
The problems such as knot machine generally existing high energy consumption, efficiency is low, poor product quality, basic reason is that sintering machine leaks out, domestic sintering
Machine air leakage rate is up to 60%, wherein gap leaks out and accounts for 17% or more of total inleakage between adjacent trolley, as trolley is worn, this
A ratio can also gradually increase.
The loop of step-by-step type sintering machine and trolley is built in one plane, and onward impulse is the car puller of head, i.e.,
Hydraulic push rod, hydraulic push rod successively release trolley, and after tail last block trolley enters tippler, tippler is by fully loaded burning
The trolley of molding is dug, and sinter is unloaded；Tail transfer vehicle is again drawn empty station vehicle successively to loop, and burning is retracted by the machine of pulling a cart
Knot machine completes a working cycles of trolley.Since step-by-step type sintering machine belongs to intermittent running device, and step-by-step type sintering machine
Trolley is placed in orbit plane, and for front and back nothing similar to the trolley compacting means of continuous pallettype sintering machine, thrust inertia be easy to cause trolley point
Drawing seam is opened, leakproofness is deteriorated, and leaks out serious；In addition at 300 DEG C or more, abrasion, deformation can cause for trolley head, tail temperature difference
Air leak rate of air curtain aggravation between trolley, raw burn, raw material return mine increase, burnup increases, yield reduces, while trolley material leakage can also cause water
It seals slide fastener load to increase, leads to Frequent Accidents.
Utility model content
Gap sealing device between a kind of marching type sintering machine trolley of the utility model offer, it is intended to adjacent by being set to
Sealing structure between two pieces of trolleys reduces the inleakage at gap position between trolley and trolley, reaches and increases the effective wind of sintering machine
Amount reduces the purpose that raw material return mine, improve Sintering Yield, reducing fuel consumption.
To achieve the above object, the utility model adopts the following technical solution：
Gap sealing device between a kind of marching type sintering machine trolley, including it is arranged symmetrically in sintering pallet left and right sides
Two parts, wherein each section are respectively provided with hydraulic drive mechanism, main shaft, branch stent and sealing strip；The hydraulic drive mechanism
It is arranged at the intermediate position of main shaft, is rotated for driving spindle；The main shaft is supported by the axle bed being fixed on level ground,
The axially disposed group of branches holder on main shaft；Gap between the branch stent two pieces of trolleys adjacent with sintering machine is opposite
It answers, sealing strip is installed on the top of branch stent.
Gap sealing device between above-mentioned marching type sintering machine trolley, the sealing strip are using double made of silica gel material
Layer flexible sealing strip.
Gap sealing device between above-mentioned marching type sintering machine trolley, the hydraulic drive mechanism include oil cylinder and push-and-pull
Arm；The oil cylinder is fixedly mounted by cylinder bracket, oil cylinder telescopic arm and push-pull arm hinge mounted；The push-pull arm is solid with main shaft
Fixed assembly.
Gap sealing device between above-mentioned marching type sintering machine trolley, the main axis length have with sintering machine exhaust equipment
Effect active length matches.
A kind of the utility model gap sealing device between marching type sintering machine trolley, it is using between step-by-step type sintering machine
Propulsion characteristic of having a rest reduces trolley by the sealing structure of Position Design and sintering machine synchronous operation between adjacent two pieces of trolleys
The position inleakage between trolley.Its operation principle is：Hydraulic drive mechanism is controlled by travel switch, is advanced and is stopped with sintering machine
Stop is made chain, and when sintering machine advances, oil cylinder backhaul action in hydraulic drive mechanism, driving spindle and branch stent revolution make
Sealing strip leaves trolley；During sintering machine cart finishes interval and pauses, oil cylinder projecting motion in hydraulic drive mechanism, driving
Main shaft drives branch stent rotation, flexible sealing strip to be acted on by sintering machine suction pressure close to trolley car body, make flexible sealing
Item tightly touch gap between two pieces of trolleys, reaches and is harmful to purpose of leaking out between reducing trolley car body.
