Abstract
A sintering machine head and tail sealing device comprises a sealing cylinder, a connecting rod, a fixed bearing block, a bearing steel base, a leaf spring, a flexible sealing material, a dust shielding plate and a counter weight device. The pressures of the sealing cylinder and the bottom surface of a sintering pallet are provided by the counter weight device, and the operation of the pallet pushes the sealing cylinder to rotate. The sealing cylinder can track a bottom beam of the pallet automatically and adjust the pressure of a contact surface at any time through counter weight adjustment as required, so that close contact of the sealing cylinder and the bottom beam of the pallet is always guaranteed, air leakage is reduced effectively, in addition, the sealing device is simple in structure and convenient to adjust and maintain. Sliding friction between the upper surface of a currently conventionally used sealing plate and the bottom of the pallet is changed into rolling friction, so that the abrasion of equipment is reduced, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to metallurgical technology field, relates in particular to a kind of sintering machine head end, tail sealing device.
Background technology.
Sintering machine is the most important equipment that iron and steel metallurgy enterprise is produced sintering deposit, and the yield and quality index of sintering deposit depends on the air quantity by sinter bed.Leaking out of existing sintering machine is generally larger, generally in about 50%-60%, and along with the use of equipment, leaking out also can be more and more serious, the energy consumption of main exhauster of sintering accounts for the over half of sintering circuit energy consumption, and therefore a lot of sintering plants all leak out minimizing as volume increase and energy-saving and cost-reducing emphasis.
In the shared ratio of air leakage rate of sintering machine, sintering machine head end, tail sealing plate leak out and account for 30% left and right.The sintering machine head end of main flow at present, tail sealing device, with chassis crossbeam bottom, bellows curb girder is rigidity contact, must leave in theory certain space and expansion space, due to seal cover board horizontal arrangement, parallel with chassis bottom surface, in actual practicality, also need to consider chassis beam deformation, the problems such as sealing plate upper surface buildup, when installation, certain interval is generally all stayed in sealing plate upper surface and chassis crossbeam bottom surface, to guarantee that chassis steadily passes through, even if some sealing device, when initial installation, sealing plate contacts with chassis crossbeam bottom surface, the pressure of contact-making surface is also very limited, affect sealing effectiveness.Because if increase interface pressure by increasing counterweight or adjusting spring, although can effectively improve sealing effectiveness, but pallet bottom and sealing plate upper surface produce very large frictional force, equipment attrition is accelerated, sealing plate is subject to very large horizontal thrust, and likely sealing plate is damaged in chassis running.
Current sintering machine head end, tail sealing device, ubiquity can not be adjusted the gap between pallet bottom and sealing plate upper surface after installing and going into operation at any time, can only chassis be hung out to limit observation limit adjustment between turn(a)round, is not easy to production operation and repair and maintenance.
Utility model content
The problem that the utility model exists for existing sintering machine head end, tail sealing device, provides a kind of new sintering machine head end, tail sealing device.
The utility model comprises: sealed cylindrical, connecting rod, fixed bearing block, bearing steel base, flat spring, encapsulant, screening hawk, counter weight device.Sealed cylindrical is arranged on link end, can rotate around cylinder axis; Connecting rod rotates within the specific limits take fixed bearing block as fulcrum, by adjusting the counterweight of the connecting rod other end, can regulate the pressure of sealed cylindrical and chassis bottom surface, to guarantee the close contact of sealed cylindrical and chassis floor beam; Sealing between sealed cylindrical and bellows adopts flat spring form, and flat spring is fixed on bellows cross-beam connecting plate, and encapsulant is fixed on flat spring, and flat spring termination is also provided with and hides grey baffle plate, reducing particle, dust falls into sealing surface.
The common You Si of sintering pallet bottom road beam, at the bottom of beam in one plane, between adjacent twice beam, it is the gusset being interspersed, gusset height is between chassis top surface of the beam and bottom surface, and theory analysis, as long as the spacing of the relative chassis bottom girder of diameter of sealed cylindrical is enough large, in each moment of chassis running, sealed cylindrical at least with together with beam close contact, reach sealing effectiveness, substituting conventional flat sealing device with sealing device cylindraceous so just becomes possibility.This technology also can be used on the similar devices beyond sintering machine.
Sintering machine head end that the utility model provides, tail sealing device are compared with existing apparatus, and its remarkable result is:
1, in sealing device, sealed cylindrical can be followed the tracks of chassis bottom girder automatically, and can adjust at any time interface pressure by adjusting counterweight as required, guarantees all the time sealed cylindrical and chassis bottom girder close contact, effectively reduces and leaks out.
2, sealing device structure is simple, adjustment, easy to maintenance.Sliding friction between current conventional sealing plate upper surface and the pallet bottom using is become to rolling friction, and equipment attrition diminishes, and increase equipment life.
Accompanying drawing explanation:
Fig. 1 is the utility model scheme of installation;
Fig. 2 is that the utility model C is to view;
Fig. 3-5th, the utility model sealed cylindrical is the signal that contacts with chassis floor beam at diverse location
In figure, A represents sintering pallet direction of advance; In Fig. 1, B represents the bottom surface of chassis 9.
The specific embodiment.
The utility model comprises sealed cylindrical 1, connecting rod 2, fixed bearing block 3, bearing steel base 4, flat spring 5, encapsulant 6, hides hawk 7, counter weight device 8.Sealed cylindrical 1 is provided by counter weight device 8 with the pressure of pallet 9 bottom surfaces, the operation of chassis 9 promotes sealed cylindrical 1 and rotates, two axle heads of sealed cylindrical 1 are equipped with rolling bearing, be arranged on respectively in the bearing block of two connecting rod 2 ends, left and right, connecting rod 2 middle part fulcrum shafts are arranged in fixed bearing block 3, and fulcrum shaft axle head is installed and rolled or sliding bearing.Bearing steel base 4 is fixed on the crossbeam of sintering machine head end subordinate skeleton.
Fig. 3-5th, in chassis 9 runnings, 3 states of sealed cylindrical 1.Chassis 9 width 1500mm in this example, sealed cylindrical 1 diameter 1000mm.Can be found out by Fig. 3-5, the configuration of above-mentioned chassis 9 and sealed cylindrical 1, under above-mentioned representational three state, sealed cylindrical 1 is beam close contact together with chassis 9 all the time, realizes effective sealing.
Sealing between sealed cylindrical 1 and bellows adopts flat spring form, and flat spring is fixed on bellows cross-beam connecting plate, and encapsulant 6 is fixed on flat spring 5, and flat spring 5 terminations are also provided with and hide grey baffle plate 7, to reduce particle sealing contact surface is affected to 2.In this example, select graphite as encapsulant 6, the contact-making surface of graphite and sealed cylindrical 1 is processed as circular shape, as shown in Figure 1.
Encapsulant 6 is to the pressure of sealed cylindrical 1 from flat spring 5, and flat spring 5 is initial while installing adjusts pretightning force take the in running order minimum point of sealed cylindrical 1 as benchmark.Hiding hawk 7 adopts sheet iron to make.
