Shown in Fig. 6, rubber slab is planar structure, and two ends are provided with tapered cylinder.
Relation between hermetically-sealed construction:
Adjustable-side sealing device be utilize blower fan system negative pressure make Wear-resistant, high-temperature resistant rubber slab outside L shape lower seal inwardly with run in seal tightly adhesive in T-shaped on chassis, realize the contact of face property.
Adjustable-side sealing device is divided into dynamically upper and static lower two large divisions's composition, and top is that dynamic T-shaped seal is dynamic, and bottom is static L shape seal.
In working order, utilize the inside exhausting of system negative pressure of Sinter air machine, cause the rubber slab outside the L shape seal of lower stationary to be inwardly tightly adsorbed on the dynamic T-shaped seal in top, form side seals.
The course of work of the present utility model and operation principle:
Adjustable-side sealing adopts heat insulation, choke, Wear-resistant, high-temperature resistant rubber slab adhesive sealing means again.The design of L shape lower seal is the effect not only playing heat insulation effect but also can reach again choke.Under suction function, Wear-resistant, high-temperature resistant rubber slab and T-shaped seal dignity and adsorbs, sealing is tight.
Be suction pressure sintering during sintering machine sintered material, make to form negative pressure in sintering machine.The operation principle of adjustable-side sealing utilizes the system negative pressure of Sinter air machine to cause wear-resisting, high-temperature flexible rubber plate to be tightly adsorbed in chassis upper seal, realizes maximization face property absorption contact.Negative pressure is larger, and adsorption area, frictional force are larger, and after reaching optimal seal effect, system negative pressure increases thereupon, forms a kind of eucyclic duty, reaches effective sealing.Blower fan system negative pressure increases, and increases the frictional force between chassis upper seal and flexible rubber plate, chassis only could be walked under the effect of external force, thus airtight end face gap between chassis and chassis, minimizing is leaked out a little again.Lower sealing assemblies designs for L shape, thus play heat insulation, again hinder wind action.Old line produces chassis lateral shift because of path wear, adjustable-side sealing device can lateral adjustments to compensate chassis side-play amount.
Feature of the present utility model:
1, high-tech research and development, reach the most long life
Wear-resisting, high-temperature flexible rubber plate is the patented product made by composite high-molecular material of my company's development, has very high wear-resisting, resistance to elevated temperatures.Connect between two plates and connect by snap close form, ensure steady in a long-term operation.The regular maintenance of a whole set of sealed product seals with traditional slideway and compares, and has the advantages such as maintenance is convenient, intensity is low, the used time is few, expense is low.
In the service life of wear-resisting, the high-temperature flexible rubber plate be made up of composite high-molecular material, chassis does not occur falling that wheel derailing is at least more than 12 months, T-shaped top seal body 3 years without the need to changing, L shape lower sealing assemblies life-span endless.
2, selection accurately with reasonably design, make product operation steady in a long-term
Chassis top seal body adopts high-abrasive material to make, impact resistance, wear-resistant.The appropriate design of its face shaping T-shaped design, can make flexible wear plate under the effect of blower fan system negative pressure, realize maximization face property absorption contact.Negative pressure is larger, and adsorption area, frictional force are larger, and after reaching optimal seal effect, system negative pressure increases thereupon, forms a kind of eucyclic duty.
Bottom L shape seal is laterally adjustable, compensates chassis side-play amount, heat insulation choke Combination Design.Bottom L shape black box divides two parts to form, and bottom is adjustable substrate, and top is the heat insulation choke holder assembly of L shape.When trolley track produces displacement after long-term use, L shape heat insulation choke assembly can carry out horizontal adjustment at any time, to compensate chassis transversely deforming amount, enables product guarantee operation steady in a long-term and reach the ideal effect sealed constantly.
3, without the need to lubrication, cost-saving
Adjustable-side sealing system revolutionizes structure and the thinking of slideway sealing in the past.Therefore, a whole set of sealing system, without the need to lubrication, also reaches Sinter air machine and electrostatic precipitator without the object worked under oil pollution environment, minimizing follow-up equipment, draught fan impeller, electrostatic precipitator pole plate, the maintenance of pole, replacement frequency, guarantee that the safety of Sinter air machine and electrostatic precipitator is normal and run.Directly save the lubrication butter of former slideway sealing, lubricating pipe and Maintenance and Repair cost, lubricating grease expense can be saved every year more than 40 ~ 600,000 yuan.
4, sealing effectiveness is obvious, and sinter quality, charge significantly improve
Generally can reduce main exhauster electric current 20 ~ 60A, obviously, sintering machine blower fan electric current reduces amplitude generally about 5 ~ 18%, and power savings is obvious in economize on electricity.Sintering stage bellows house steward negative pressure on average improves about 2.5KPa, and cooling section bellows house steward negative pressure on average improves about 1.3KPa, and waste gas oxygen content reduces by 28%, and sintered discharge gas temperature generally raises 50 ~ 110 DEG C.Temperature can meet the requirement of cogeneration after improving.Sintering, cooling procedure speed are accelerated, and sinter quality, charge significantly improve.
5, be widely used
This adjustable-side sealing system can not only be used for the transformation of sintering machine, can be applied to equally on the sintering machine equipment of grassroot project.Due to the sealing effectiveness that side seal is good and stable, compared with sealing with traditional slideway, As time goes on sealing effectiveness can not be reduced.Therefore, grassroot project is as selected combined type side-sealing system, and its design air distribution amount just can save more than 10%, and corresponding necessary electromotor power and dust catcher select can reduce a model, the minimizing of inleakage ensure that the rising of EGT, thus guarantees the optimum efficiency of heat recovery.
6, easy for installation
Original chassis trip plate is changed side seal seal, and the original sealing chute of cut-out also welds upper adjustable substrate, installs the heat insulation choke seat of L shape and flexible rubber plate plate.
7, repair and maintenance cost is low
This adjustable-side sealing system, after using for a long time, only need change wear-resisting, high-temperature flexible rubber plate plate if any air leakage phenomena.
Facts have proved, no matter adjustable-side sealing device is retrofitting of used machine or grassroot project, is a small investment, instant effect, invests cost-recovering and the project with little investment but quick effect of current year profit then then.The special structure form of this product and rational design concept, fundamentally solve sintering machine to leak out an insoluble difficult problem, for the current reduction production cost of enterprise, reduction energy consumption, raising sintering usage factor, energy-saving and emission-reduction open a shortcut, are field technology revolutions of sintering machine air-leakage control.
