Abstract
Disclosed is a plate type sealing device with floating gravity hammer of a sintering machine, belonging to the field of metallurgical mechanical device. The plate type sealing device with floating gravity hammer is used on the end or the middle of the sintering machine, solving the problem of air leakage or air through between a trolley and an air box. The plate type sealing device with floating gravity hammer comprises an upper sealing plate 1, a lower sealing plate 2, a bearing seat 3, a lever 4, a gravity hammer 5, a limiting correcting draw rod 6. The plate type sealing device with floating gravity hammer is characterized in that the upper sealing plate is contacted and sealed with the flat face of the trolley; the upper sealing plate is contacted and sealed with the curved face of the air box through the lower sealing plate and the bearing seat. The utility model has the advantages of compact structure, high reliability, low cost and long service life.
Description
The utility model belongs to the metallurgical machinery equipment field, particularly the unsteady board-like seal arrangement of a kind of weight of sintering machine.
This device is used for sintering machine head and the tail end, solves leaking out between head and the tail chassis bottom surface, two ends and bellows, or is used for the joint of sintering machine middle part two adjacent bellows, solves the string wind between the bellows.
In prior art, comparatively ideal sintering machine end seal is known weight four connecting rod float plate seal arrangements, and this apparatus structure is reasonable, and sealability is good, but remains in following shortcoming:
(1) main sealing component mountain flesh plate is shorter working life, general only 6～12 months life-span.
(2) the mountain flesh plate is special dedicated sealing member, and manufacturing technology is complicated, needs special manufacturer production, and cost is very high.
The purpose of this utility model is to overcome the low and high shortcoming of cost of mountain flesh plate life-span in the said apparatus.
For achieving the above object, the utility model provides a kind of and does not adopt the mountain flesh plate and adopt the novel weight of the lower seal plate board-like seal arrangement that floats between upper sealing panel and bellows.The lower seal plate of this device, its two ends are respectively the special linkage structure of bag arc less than axle with the bearing of 360 degree with the linkage structure between upper sealing panel and the bellows, and this connection part has enough area of contact, has reliable sealing function.The metallic material manufacturing of lower seal plate, comparable mountain flesh plate of life-span prolongs 2-4 doubly, and cost can reduce greatly.
The principle of the unsteady board-like seal arrangement of this weight is seen accompanying drawing 1.Shown in figure, this device is made up of upper sealing panel 1, lower seal plate 2, supporting base 3, lever 4, weight 5 and spacing levelling pull bar 6 etc., and the associated components around when installing on sintering machine has bellows 7 and chassis 8 etc.
Supporting base 3 among the figure, upper end have the axle of bag arc less than 360 degree.
Centre distance between upper sealing panel 1 among the figure, lower seal plate 2 and two supporting bases 3 constitutes parallelogram, under the action of gravity of weight, upper sealing panel 1 level come-up and with the bottom surface contact seal of chassis 8.
The utility model seal arrangement is characterised in that lower seal plate 2 with the linkage structure between upper sealing panel 1 and the supporting base 3, is respectively that the bag arc is less than 360 axles of degree and being connected of bearing.
When implementing the utility model,, can suitably select wrapping the number of degrees of arc in the linkage structure of bag arc less than the axle of 360 degree and bearing.Generally can select for use greater than 180 degree or equal 180 and spend.When the bag arc is selected for use when spending greater than 180, can not throw off on axle and the unsteady direction of being connected of bearing, operational reliability is the highest.Select for use when the bag arc and to equal 180 degree or when spending, the maintenance easy accessibility less than 180.
This apparatus features is: all member is rigid member, does not have flexible element and spring part.All the connection part between the member is the plane contact sealing or the curved surface contact seal of area contact property.
Embodiment one
See accompanying drawing 1.Accompanying drawing 1 is a most preferred embodiment of the present utility model, characteristics be simple in structure, boundary dimension is little.Be fit to be installed on the head and the tail end of sintering machine.Lower seal plate 2 near bellows among the figure has sealing function, and away from the lower seal plate 2 of bellows, only play the rod member effect, do not have sealing function, therefore away from the lower seal plate 2 of bellows, also can replace with common rod member, its two ends are connected with upper sealing panel 1 and supporting base 3, can connect with common hinge.
Embodiment two
Seeing accompanying drawing 2, is the embodiment with quadratic crank mechanism traditional form.Be fit to be installed on the head end portion of sintering machine.Lower seal plate 2 near bellows among the figure has sealing function, and another lower seal plate 2 does not have sealing function.
Embodiment three
See accompanying drawing 3: be the embodiment who is fit to be installed between the two adjacent bellows of sintering machine middle part.
Embodiment four
Seeing accompanying drawing 4, is the embodiment who is fit to be installed between sintering machine head and the tail end or the adjacent bellows in middle part.Characteristics are that two lower seal plates 2 all have sealing function, and shortcoming is may dust stratification between two lower seal plates 2.
More than each embodiment, the bag arc of connection part between lower seal plate 2 and upper sealing panel 1 and the supporting base 3, all select greater than 180 degree, because such bag arc, area of contact is big, good seal performance, upper sealing panel 1 is when fluctuating simultaneously, and each connection part can not thrown off on the direction of floating, and is reliable.
The various embodiments described above, according to the difference of chassis 8 width, upper sealing panel 1 and lower seal plate 2 can be divided into 3～5 on chassis 8 width directions, to adapt to " waist collapses " distortion of chassis.
The advantage of this device:
(1) all member is hardware, and is easy to manufacture, cheap.
(2) service life longer, be expected to reach overhaul life of a sintering machine, can use in one at least and repair the cycle (more than 3 years).
(3) simple and reliable for structure, fault is few, and the Maintenance and Repair workload is few.
(4) appearance and size is little, and the position that takies sintering machine is less, uses all practical and feasible at new, old sintering machine.
Each member method manufacturings such as casting or rivet welding of this device, requirement on machining accuracy is not high.
The material of each member of this device does not have specific (special) requirements, can adopt cast steel, cast iron or other metal material manufacturing.
