Abstract
The utility model provides a sealing device arranged between the transmission rod and the wind separating board of the reciprocal grate of boilers, comprising a sealing sleeve, an upper sealing plate and a lower sealing plate. The transmission rod reciprocates in the sealing sleeve; sliding movement is generated between the sealing sleeve and the upper and lower sealing plates clamped in the grooves of the sealing sleeve; the upper and lower sealing plates are fixed on the wind separating board and through holes are closed off. The utility model has the advantages of favorable sealing performance, high durability, long service life, simple structure, easy parts manufacturing, labor saving in disassembling and assembling, convenient maintenance.
Description
The utility model is a kind of seal arrangement that is used between boiler reciprocating grate drive link and the wind isolation board.
Reciprocating grate is simple in structure, and metal consumption is few, and it rolls the coal seam generation in the process of propellant, and there are loose and mixed function in the coal seam, impels coal fully to burn, thereby reciprocating grate has obtained using widely in industrial boiler.Reciprocating grate is driven by the drive link that is installed in below the fire grate, and therefore the wind isolation board between each air compartment of drive link break-through has produced sealing problem between drive link and wind isolation board through hole.Before the utility model was made, rubber or asbestos packing were adopted in the sealing between drive link and the wind isolation board through hole usually.Not only to-and-fro motion vertically of drive link in transmission process, and with horizontal moving back and forth, so rubber or asbestos packing be easy to generate distortion, wearing and tearing, often is subjected to temperatures involved, easier damage simultaneously.So, produce between each air compartment and scurry wind, influence the blast control in the air compartment, cause and transfer the wind difficulty, and increase burner hearth and leak out, the result influences burning, the thermal efficiency of reduction boiler.Therefore must often change the sealing material between drive link and the wind isolation board, this has brought trouble for the maintenance of boiler.
The purpose of this utility model provides a kind of seal arrangement that is used between reciprocating grate drive link and the wind isolation board, prevents to scurry wind between the boiler air compartment, reduces burner hearth and leaks out, smooth combustion, thereby the thermal efficiency of raising boiler.
The seal arrangement that the utility model proposes is made up of stuffing box gland, upper sealing panel and lower seal plate, stuffing box gland is provided with outer groove, endoporus has a convex shoulder, stuffing box gland is enclosed within on the fire grate drive link, leave the gap between convex shoulder endoporus and the drive link, upper and lower sealing plate is stuck in the groove, and and the groove inner side surface between leave the gap, upper and lower sealing plate around be fixed on the wind isolation board again, and sealed the through hole that the break-through drive link is reserved on the wind isolation board.In transmission process, drive link is to-and-fro motion in stuffing box gland, stuffing box gland is along with the motion of drive link, stuffing box gland and be stuck in also to produce between the upper and lower sealing plate in its groove and laterally reciprocatingly slide, because the upper-lower seal plate is fixed on the wind isolation board all the time, and sealed the through hole on the wind isolation board, therefore the utlity model has good seal action.
This seal arrangement is compared not only favorable sealing property with traditional rubber or asbestos seal, and not fragile, long service life.In addition, this sealing device structure is simple, and part processing is easy, and dismounting is laborsaving, is convenient to maintenance.
Describe the details of this seal arrangement in detail below in conjunction with accompanying drawing, Figure 1 shows that the structural drawing of this seal arrangement, Figure 2 shows that the rigging position figure of this seal arrangement in the reciprocating grate driving mechanism.
This seal arrangement is made up of stuffing box gland (2), upper sealing panel (1) and lower seal plate (3), stuffing box gland (2) is provided with outer groove, one convex shoulder is arranged in its circular inner hole, stuffing box gland (2) is enclosed within on the fire grate drive link (4), gap between convex shoulder endoporus and the drive link (4) is 0.1～0.2mm, thus make stuffing box gland (2) endoporus shaft axis and hard-over that level becomes be 1 ° 40 '.Upper sealing panel (1) and lower seal plate (3) are stuck in the outer groove of stuffing box gland (2), and and the groove inner side surface between the gap be 0.2～0.5mm, be fixed on again on the wind isolation board (5) around the upper and lower sealing plate (1,3).Therefore in transmission process, drive link (4) in stuffing box gland (2) to-and-fro motion and with situation about laterally moving back and forth under, stuffing box gland (2) and be stuck in also to produce between the upper and lower sealing plate (1,3) in its groove and laterally reciprocatingly slide, upper and lower sealing plate this moment (1,3) are fixed on all the time that wind isolation board (5) is gone up and the sealing through hole.
In addition, when the drive link cross section was rectangle, the endoporus of the stuffing box gland of seal arrangement also can correspondingly change rectangle into, and this moment, endoporus shaft axis and horizontal angle should be 9 °.
Claims (1)
- A kind of seal arrangement that is used between boiler reciprocating grate drive link and the wind isolation board, it is characterized in that it is by stuffing box gland, upper sealing panel and lower seal plate are formed, stuffing box gland is provided with outer groove, one convex shoulder is arranged in its circular inner hole, stuffing box gland is enclosed within on the fire grate drive link, gap between convex shoulder endoporus and the drive link is 0.1～0.2mm, make stuffing box gland endoporus shaft axis and hard-over that level becomes be 1 ° 40 ', on, the lower seal plate be stuck in the outer groove of stuffing box gland and and the groove inner side surface between the gap be 0.2～0.5mm, on, be fixed on the wind isolation board and sealed the through hole on the wind isolation board around the lower seal plate.
