Description
Technical field
Patent of the present invention relates to the technical field of sintering machine for metallurgy equipment, and particularly a kind of end is with the sintering pallet of sealing device.
Background technology
In the field of sintering machine equipment, the air leak rate of air curtain of sintering machine sealing just affects Yield and quality and the cost of sintering deposit, and sintering industry is all being found the method that reduces air leak rate of air curtain both at home and abroad.Domestic air leakage rate of sintering machine is controlled at 50% ~ 60% at present, in the shared ratio of air leak rate of air curtain, head and the tail seal cover board accounts for 29%, slideway accounts for 17%, trolley body 11%, breast board 15%, air path system 27%, the end proportion of sintering machine is maximum thus, and it is even more important that the assurance of end part seal also seems.Head, the tail seal device of sintering machine almost all adopt four link type sealing mechanism now, the residing location circumstances of sealing mechanism is poor, dust is more, in addition temperatures involved, usually occur that four connecting rod activities are malfunctioning, the resistance of top seal board, fluctuates thereby make sealing plate can not be close to trolley body, loses sealing property.When sintering machine runs well, between chassis and sealing plate, there is gap, more than reaching 30 mm when maximum, thereby cause large area herein to leak out, lose sealing effectiveness.
Summary of the invention
The object of this invention is to provide a kind of simple in structurely, operate steadily, reliably, cheap, change simply and easily end with the sintering pallet of sealing device.
The object of the invention is to realize by following technical proposals:
End of the present invention is with the sintering pallet of sealing device, comprise trolley body, it is characterized in that being provided with one group of connection board in trolley body bottom, this group of connection board is connected with the upper end of one group of high temperature resistant rigidity spring leaf respectively, the lower end of this group of high temperature resistant rigidity spring leaf is connected with the upper end of one group of Wear-resistant, high-temperature resistant sealing plate respectively, and the lower end of this group of Wear-resistant, high-temperature resistant sealing plate is all slidably connected with the sealing beam surface upper of sintering machine.
Described connection board is provided with row's riser through hole, the both ends up and down of described high temperature resistant rigidity spring leaf are provided with respectively the upper connecting hole of a row and lower connecting hole, the upper end of described Wear-resistant, high-temperature resistant sealing plate is provided with row's sealing plate through hole equally, and the two ends up and down of described high temperature resistant rigidity spring leaf are connected with Wear-resistant, high-temperature resistant sealing plate with described connection board by one group of bolt fastener respectively.
Described Wear-resistant, high-temperature resistant sealing plate is the bent plate along horizontal horizontal line bending.
Advantage of the present invention:
The high temperature resistant rigidity spring leaf that the present invention arranges, makes connected Wear-resistant, high-temperature resistant sealing plate have elastic floating, and maintenance contacts with the sealing beam surface upper sealing of sintering machine, and simple in structure, operate steadily, reliably, cheap, change simple and convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the I place enlarged drawing of Fig. 1 of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present invention.
As shown in Figure 1 and Figure 2, end is with the sintering pallet of sealing device, comprise trolley body 1, it is characterized in that being provided with one group of connection board 6 in trolley body 1 bottom, this group of connection board 6 is connected with the upper end of one group of high temperature resistant rigidity spring leaf 2 respectively, the lower end of this group of high temperature resistant rigidity spring leaf 2 is connected with the upper end of one group of Wear-resistant, high-temperature resistant sealing plate 3 respectively, and the lower end of this group of Wear-resistant, high-temperature resistant sealing plate 3 is all connected with sealing crossbeam 5 upper surface slide of sintering machine.The every distance between adjacent of one group of Wear-resistant, high-temperature resistant sealing plate 3 is set to be less than the upper surface width of sealing crossbeam 5.
Described connection board 6 is provided with row's riser through hole, the both ends up and down of described high temperature resistant rigidity spring leaf 2 are provided with respectively the upper connecting hole of a row and lower connecting hole, the upper end of described Wear-resistant, high-temperature resistant sealing plate 3 is provided with row's sealing plate through hole equally, and the two ends up and down of described high temperature resistant rigidity spring leaf 2 are connected with Wear-resistant, high-temperature resistant sealing plate 3 with described connection board 6 by one group of bolt fastener 4 respectively.
Described Wear-resistant, high-temperature resistant sealing plate 3 is the bent plate along horizontal horizontal line bending.
In figure, arrow direction is sintering pallet traffic direction, and the bending direction of Wear-resistant, high-temperature resistant sealing plate 3 is contrary with chassis traffic direction,
Operation principle of the present invention is:
Chassis runs into sealing crossbeam 5 along chassis traffic direction, because being shaped as along trolley body traffic direction of Wear-resistant, high-temperature resistant sealing plate is crooked backward, just can enter smoothly sealing crossbeam region, high temperature resistant rigidity Spring deformation now, Wear-resistant, high-temperature resistant sealing plate 3 is tightly pressed in to the upper surface of sealed beam 5, plays excellent sealing effect.Each chassis is generally provided with San Zhi tetra-road Wear-resistant, high-temperature resistant sealing plates 3, because the width of sealing crossbeam 5 is greater than the distance of adjacent Wear-resistant, high-temperature resistant sealing plate 3, be enough to guarantee that any moment has at least one group of Wear-resistant, high-temperature resistant sealing plate 3 to play sealing function, guaranteed the continuity of sealing.
Wear-resistant, high-temperature resistant sealing plate 3 is connected and fixed by bolt fastener 4, can dismantle at any time, change, and only need can complete in chassis backhaul, without parking while changing Wear-resistant, high-temperature resistant sealing plate 3.The present invention is simple in structure, operates steadily, reliably, cheap, changes simple and convenient.
