Abstract

The utility model relates to a sealing device for side gap of a trolley heating furnace or a trolley heat-treatment furnace. The upper part of the utility model is provided with a bracket which is fixed on the furnace wall and refractory fiber blocks which are arranged at the both sides of the trolley; the lower part of the utility model is provided with refractory fiber blocks which are opposite with the refractory fiber blocks which are arranged at the both sides of the trolley and are fixed on the bracket on the upper end of a lifting cylinder; the upper and lower refractory fiber blocks can contact tightly to seal the side gap of the trolley by opening the lifting cylinder. The upper refractory fiber block can also be a T-shaped sand sealing knife. The utility model has the advantages of reliable seal and reasonable structure.

Description

The utility model is the sealing device of chassis sideshake, and it belongs to chassis heating furnace or Type Car-bottom Heat Treating Furnace field.
Car type furnace is when work, because its chassis need pass in and out burner hearth, thereby certain clearance (being the chassis sideshake) arranged between chassis (3) both sides and furnace wall (8) (see figure 1), form and stove size according to track, the size of chassis sideshake (δ) is generally the 50-80 millimeter, and the existence in gap makes that when burner hearth was negative pressure, cold air can suck, and high-temperature furnace gas escapes when burner hearth is malleation, and these all influence the uniformity of furnace temperature.
In existing car type furnace, the sealing of chassis sideshake is by the sand seal device.The sand seal device is made up of the sand sealing knife (2) of sand sealing groove that is contained in the chassis both sides (1) and both sides, furnace wall bottom, and sand sealing knife is inserted in the sand sealing groove that fills sand.Because sand itself has gas permeability, add chassis turnover burner hearth sand is taken out of outside the stove, and make sand less and less, so sealing effectiveness is poor.Because sand seal is not tight, if the burner hearth malleation is high slightly, and flame promptly runs downwards and emits and sand sealing knife is burnt out, the outer this structure that furnace wall is arranged of building of sand sealing knife in addition, make observe and maintenance very inconvenient.
The purpose of this utility model provides a kind of sealing device of chassis sideshake, and its sealing is reliable, rational in infrastructure.
The technical scheme that the utility model achieves the above object is:
A kind of sealing device of chassis sideshake, comprise the upper and lower, it is characterized in that: the top of sealing device is for being fixed on furnace wall support (5) (Fig. 3) and the refractory fiber block (4) under the sealing plate (9) of chassis (8) both sides, the lower plane (S) of homonymy refractory fiber block (4) is on a horizontal plane, the bottom of sealing device is another refractory fiber block (10) that horizontal plane is relative therewith, and this refractory fiber block (10) is fixed on the support (11) of jacking cylinder (7) upper end.
The support (11) of this jacking cylinder (7) upper end can make the radial type (see figure 7), and jacking cylinder (7) can be a piston type cylinder, also can be piston-type hydraulic cylinder.The top of sealing device can change T shape sand sealing knife (12) (see figure 10) that is fixed on furnace wall support (5) and chassis (8) both sides into, and the bottom of sand sealing knife (P) roughly is on the horizontal plane.
The utility model compared with prior art has following advantage:
(1) refractory fiber block is all sealed the chassis sideshake reliably; the suction of cold air and escaping of high-temperature furnace gas have been stoped; thermal radiation in the isolated effectively stove; the temperature difference reduces in the uniformity of temperature profile that makes the chassis left and right sides, stove, fuel consumption reduces; also protect the car type furnace hardware not burnt out, prevent the temperature distortion of stove inner orbit.
(2) owing to substituted the building block of furnace wall following side with furnace wall support (5), this rational structure makes this place vacate enough spaces, thereby not only can directly observe the sealing situation of sealing device, and can also keep in repair sealing device easily from the chassis sidepiece to the chassis sideshake.
The support of this jacking cylinder upper end makes radial type, can be when the lower plane (S) of the refractory fiber block (4) on sealing device top be not on a horizontal plane, can rotate adjustment, and the refractory fiber block (10) of sealing device bottom still can closely be contacted with top, thereby be particularly suitable for the installation of the sealing device of elongated car type furnace, the jacking cylinder can be piston type cylinder or piston-type hydraulic cylinder, can improve the interchangeability of sealing device, satisfy the requirement of different user, sealing device top changes T shape sand sealing knife into, then require the bottom (P) of T shape sand sealing knife, only need roughly be on the horizontal plane and get final product, therefore it is installed and adjusts easily, next is a refractory fiber block (4) of having cancelled top, also avoid refractory fiber block easy peeling phenomenon that produces in folding repeatedly over a long time on top, further improved the reliability of sealing device.

Now in conjunction with the embodiments the utility model is described in further detail:
Under the sealing plate (9) of furnace wall support (5) and chassis (8) both sides, be welded with a row little hook (15), then iron rod (16) is inserted in the middle refractory fiber block (4) of two little hooks, and makes the lower plane (S) on a horizontal plane (Fig. 3) of refractory fiber block (4).Jacking cylinder (7) is placed in below at chassis sideshake (δ), the support (11) of jacking cylinder upper end has a Baltimore groove, refractory fiber block (10) is placed in the groove, its bottom is bonding with glue and groove with refractory fibre, refractory fiber block (4,10) all adopts the aluminosilicate refractory fiber goods, and its thickness is about 150 millimeter.The quantity of the jacking cylinder of every side is looked the stove size, is provided with one every 3-5 rice.Jacking cylinder (7) can adopt piston type cylinder (160 millimeters of cylinder bores, 160 millimeters of piston strokes, operating pressure are 0.5-0.7MPa), or adopts piston-type hydraulic cylinder (100 millimeters of cylinder bores, 160 millimeters of piston strokes, operating pressure are 1-1.5MPa).When car type furnace is worked, it is in place that chassis enters burner hearth, and cylinder (or hydraulic cylinder) ventilation (or fuel feeding) promotes piston rod (6) upwards, refractory fiber block (10) on the support is close to the refractory fiber block (4) of furnace wall support and chassis side, and the chassis sideshake is all sealed.When the car type furnace end-of-job, cylinder is oppositely ventilated (or the reverse fuel feeding of hydraulic cylinder), piston rod (6) return, and refractory fiber block disengages about making, and at this moment chassis can withdraw from burner hearth.
The support (11) of jacking cylinder upper end is if make the radial type (see figure 7), then be that the support (11) that sealing device bottom refractory fiber block (10) is housed is supported on the axle that can rotate around it (13), axle is by the snap ring (14) at two ends, be fixed on the carriage (17) on the jacking cylinder, as Fig. 8, shown in Figure 9.
If change sealing device top into T shape sand sealing knife (12), then only need remove refractory fiber block (4), T shape sand sealing knife (12) is built respectively to go in furnace wall support (5) and the chassis (8), and make the bottom (P) of T shape sand sealing knife roughly be in (see figure 10) on the horizontal plane.Make progress by the preceding described piston rod (6) of cylinder (or hydraulic cylinder) that makes, the bottom (P) of T shape sand sealing knife is inserted in the sealing device bottom refractory fiber block (10), finish the sealing of chassis sideshake.
