Description
Technical field
The utility model relates to a kind of sealing device, relates in particular to the independent contact type sealing device regulating of realized multiple directions that grate-cooler longeron runs through the sealing of air compartment place.
Background technology
Sealing is to prevent that fluid or solia particle are from leaking between adjacent faying face and preventing parts or the measure that introduced contaminants is invaded machinery equipment inside as dust and moisture etc., and its application relates to the every aspect of social production.Whether according to seal and there is relative motion sealing can be divided into static seal and the large class of movable sealing two between seal, in movable sealing field, whether the parts of doing relative motion by seal and its again contact, and can be divided into contact seal and non-contacting seal.The contact seal that is movable sealing field that the utility model is related.
Contact seal is with fitting tightly between seal and relative movement part, to realize the effect of sealing.Thereby seal and will inevitably be caused the wearing and tearing of seal to cause seal failure by the relative motion between seal.The example that is sealed into grate-cooler walking beam, grate-cooler walking beam runs through the whole longitudinal direction of grate-cooler, front-rear reciprocation movement is done in the grate unit that drive is located thereon, at grate-cooler walking beam, wear the position of air compartment baffle, for fear of the string wind between adjacent plenum, adopt contact type sealing structure design in order to realize the sealing effectiveness of adjacent plenum more.This contact seal is subject to spatial limitation generally not have wear-compensating and adjusts function, and depend on the abrasion resistance of seal its sealing life, if can not artificially adjust in time, change the seal of inefficacy after sealing part abrasion, sealing effectiveness is had a greatly reduced quality.
Utility model content
For above problem the utility model, provide a kind of multidirectional sealing device with adjustable of wearing air compartment place for grate-cooler longeron, under normal service condition, can make seal keep in touch all the time with by seal, improved sealing effectiveness, even also can be by manually adjusting again enhanced leaktightness part and by the adhesive force between seal, having improved greatly the utilization rate of seal in the situation that of seal excessive abrasion.
In order to overcome the above problems the utility model, provide a kind of multidirectional sealing device with adjustable of wearing air compartment place for grate-cooler longeron, it is characterized in that: comprised peripheral frame, wedge type block, wedge seal, long bolt, short screw, movable part, rectangular seal part, holddown spring one, adjust plate, holddown spring two; Holddown spring one is sleeved on through applying thrust to adjusting plate on the short screw of peripheral frame bottom; Long bolt is through peripheral frame bottom and adjust plate, and holddown spring two is sleeved on long bolt wedge type block is applied to thrust; Rectangular seal part is positioned to be adjusted on plate and fits with movable part lower surface; The inclined-plane of wedge seal and the laminating of the inclined-plane of wedge type block, the vertical plane of wedge seal and the laminating of the side of movable part; Peripheral frame is positioned at wedge type block, wedge seal, movable part, rectangular seal part, adjusts outside plate.
This sealing device is used for realizing the multidirectional sealing to movable part, utilizes adjusting screw(rod) to regulate the pretightning force of holddown spring, thereby seal and movable part are fitted tightly, thereby realize the sealing effectiveness to movable part.The distinguishing feature of sealing device is to utilize the component effect of wedge type block, screw rod by single direction is regulated when just can realize multiple directions to be compressed, thereby avoided traditional multidirectional sealing device to need each to regulating respectively the drawback compressing, reduced the volume of multidirectional pressed sealing device, also make multidirectional sealing compress adjustment structure and simplify, be easy to adjust.Meanwhile, thus sealing device also can adjust respectively the thrust of all directions and make all directions all reach best sealing effectiveness.
The perforate that the bottom of peripheral frame supplies long bolt and short screw to pass is screwed hole, adjusting the perforate of passing for long bolt on plate is unthreaded hole, by twisting screw rod, just can adjust the thrust that imposes on seal like this, and then realized the adjustment to the adhesive force between seal and movable part, improved sealing effectiveness, and the adhesive force between each seal and movable part can be distinguished adjustment as required, non-interference.
Multidirectional sealing device with adjustable of the present utility model is simple in structure clear, and easy operating is realized multidirectional press seal by unidirectional adjustment, and the design that simplifies the structure, has saved space resources.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In Fig. 1: 1-peripheral frame; 2-wedge type block; 3-, wedge seal; 4-long bolt; 5-short screw; 6-movable part; 7-rectangular seal part; 8-holddown spring one; 9-adjusts plate; 10-holddown spring two.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of multidirectional sealing device with adjustable of wearing air compartment place for grate-cooler longeron, comprises peripheral frame 1, wedge type block 2, wedge seal 3, long bolt 4, short screw 5, movable part 6, rectangular seal part 7, holddown spring 1, adjusts plate 9, holddown spring 2 10; Holddown spring 1 is sleeved on through applying thrust to adjusting plate 9 on the short screw 5 of peripheral frame 1 bottom; Long bolt 4 is through peripheral frame 1 bottom and adjust plate 9, and holddown spring 2 10 is sleeved on long bolt 4 wedge type block 2) apply thrust; Rectangular seal part 7 is positioned to adjust on plate 9 and with movable part 6 lower surfaces fits; The inclined-plane 3-1 of wedge seal 3 and the inclined-plane 2-1 of wedge type block 2 laminating, the vertical plane 3-2 of wedge seal 3 and the side 6-1 of movable part 6 laminating; Peripheral frame 1 is positioned at wedge type block 2, wedge seal 3, movable part 6, rectangular seal part 7, adjusts outside plate 9.
The perforate that the bottom of peripheral frame 1 is passed for long bolt 4, short screw 5 is screwed hole.
Adjusting the perforate of passing for long bolt 4 on plate 9 is unthreaded hole.
Under nominal situation, under the spring-force driven dual of holddown spring 1 and holddown spring 2 10, rectangular seal part 7 and wedge seal 3 are adjacent to and realize sealing effectiveness with the base of movable part 6 and dual-side respectively.
When seal excessive abrasion and spring force when being not enough to apply enough thrusts and making the laminating of seal and movable part, can by long bolt 4 and short screw 5, adjust respectively, recover the thrust of spring, thereby make between seal and movable part, again to keep fitting tightly state.Its concrete adjustment mode is:
Tighten short screw 5, compression holddown spring 1, under the effect of pressing force of the spring, adjusts plate 9 and moves up, and makes rectangular seal part 7 and movable part 6 bottoms keep laminating.
Tighten long bolt 4 and make holddown spring 2 10 compress wedge type block 2, under the cross component force effect of wedge type block 2, wedge seal 3 fits tightly with the side of movable part 6, realizes sealing.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
