Description

Trolley board of sintering machine clearance sealing device

Technical field

The utility model relates to metallurgical technology field, relates in particular to a kind of trolley board of sintering machine clearance sealing device.

Background technology

Sintering pallet when design of prior art because consider distortion, the factor such as expand with heat and contract with cold, breast board is established timing length can be than the short 1mm of chassis car body left and right, concrete meeting is with differences such as chassis size, structure, materials, adding the severe working environments such as high temperature, high dust content, gap in actual production between any two trolley breast plates can be larger, and the increase along with service time, this gap can be increasing, to a certain degree increase the inleakage of sintering machine, thereby have influence on the energy consumption index of sintering deposit, be unfavorable for that sintering deposit is produced energy-saving and cost-reducing.

There are some problems in existing sintering machine breast board Gap Sealing Technology, comprises that sealing device structure rigidity is inadequate, resistance to elevated temperatures is poor, to bad adaptability of breast board displacement etc.

Utility model content

The utility model provides a kind of trolley board of sintering machine clearance sealing device, can effectively reduce trolley breast plate gap and leak out.

The utility model comprises sealing plate 1, hangers 2, axle 3, pad 4, pin 5, flat spring 6, screw 7.The technical scheme adopting is: sealing plate 1 is circle with the sealing contact surface of trolley breast plate 8, the state that can adapt to different breast board 8, under different breast boards 8 states, can effectively contact with the trolley breast plate 8 of both sides, gap, the linkage that this process is comprised of sealing plate 1, hangers 2, axle 3, flat spring 6 etc. completes, flat spring 6 is all the time in a kind of oppression state, and the tension force of flat spring makes the circular contact-making surface of sealing plate 1 compress all the time the trolley breast plate of both sides, gap.Fig. 1 is the scheme of installation of this device, and in figure, A is sintering pallet direction of advance under production status.

This sealing device is arranged on chassis traffic direction chassis sideboard 8 rear sides near gap location.In the running of chassis, chassis from the head bend out after adjacent chassis sometimes have micro-dislocation, cause adjacent trolley breast plate 8 also to have certain dislocation, the linkage that this sealing device is comprised of sealing plate 1, hangers 2, axle 3 and flat spring 6 etc. can effectively adapt to this dislocation state of breast board, the circular contact-making surface of sealing plate 1 is effectively contacted with the breast board 8 of both sides, gap all the time, see Fig. 2.

In chassis actual production running, chassis overturns from bottom to top at sintering machine head, in chassis below and next-door neighbour's the complete contact process of anterior chassis, because the seal contact-making surface of sealing plate 1 is circular, the breast board 8 of rear portion chassis contacts with the circular seal body of sealing plate 1, produce outside thrust, the connecting rod band moving axis 3 of sealing plate 1 is along the circular arc fluting down sliding of hangers 2, interlinking lever end also moves downward, flat spring 6 produces larger masterpiece for sealing plate 1, make the pressure of sealing contact surface larger, more effectively reducing trolley breast plate 8 gaps leaks out, and in whole sintering process, keep this state, see Fig. 3.

Chassis runs to sintering machine afterbody bend, and adjacent chassis is separated from each other, and in chassis separation process, the circular seal body of sealing plate 1 is toward side direction skew in breast board, and the connecting rod band moving axis 3 of sealing plate 1 moves upward along the circular arc fluting of hangers 2.

The linkage of this device has adaptability while reversing for sintering machine too, possesses practical value.

This apparatus structure is simple, there is certain rigidity, the different dislocation state of the adjacent trolley breast plate 8 of sintering machine is had to certain adaptivity, be adapted at continuous operation under the environment such as high temperature, dust, vibration, device is made simple, stable, effectively reduce the adjacent trolley breast plate of sintering machine 8 gaps and leak out, be conducive to reduce SINTERING PRODUCTION energy consumption.

the specific embodiment

The utility model comprises sealing plate 1, hangers 2, axle 3, pad 4, pin 5, flat spring 6, screw 7.Hangers 2 is integrated with breast board 8, with breast board 8, design together, cast processing, flat spring 6 use screws 7 are fixed on trolley breast plate 8, and flat spring upper press becomes U-shaped groove, refers to Fig. 7, Fig. 8, sealing plate 1 is comprised of circular seal body and connecting rod, refer to Fig. 5, Fig. 6, Fig. 5 bottom is circular hollow sealing body, and two ends are connecting rod, sealing plate 1 monoblock cast, the external side contacts face of circular seal of close trolley breast plate 8 directions requires as machined surface.The connecting rod of sealing plate 1 is placed in the groove of flat spring 6 upper press one-tenth, and the connecting rod of sealing plate 1 forms linkages by axle 3 and hangers 2, and both sides are located by pad 4 and pin 5.The pretightning force of linkage circular seal body is provided by the flat spring of interlinking lever end, and on hangers 2, fluting, for the circular-arc groove of the center of circle at breast board gap location, effectively contacts the seal of sealing plate 1 adaptively with the breast board of both sides, trolley breast plate gap.

This sealing device is arranged on chassis rear side near breast board 8 gap locations, and the circular seal face of sealing plate 1 is pressed on the breast board 8 of both sides, gap, and can adjust adaptively position.In the running of chassis, chassis from the head bend out after adjacent chassis sometimes have micro-dislocation, cause adjacent trolley breast plate 8 also to have certain dislocation, the linkage that this sealing device is comprised of sealing plate 1, hangers 2, axle 3 and flat spring 6 etc. can effectively adapt to this dislocation state of breast board 8, and the circular seal contact-making surface of sealing plate 1 is effectively contacted with the breast board 8 of both sides, gap all the time.

Because trolley breast plate 8 generally has three layers along vertical, between the adjacent two layers of breast board 8, there is protruding gusset, so each chassis distributes 3 sealing devices, sealing surface disconnects at the gusset place of trolley breast plate 8, sees Fig. 1.

The foregoing is only the utility model preferred embodiments, not in order to limit the utility model, all any modification, replacement and improvement etc. of making within spirit of the present utility model and principle, within all should being included in protection domain of the present utility model.
