Abstract
The utility model provides a continuous annealing furnace and a furnace gas sealing structure thereof. The furnace gas sealing structure of a continuous annealing furnace comprises sealing grooves and sand knives, the sand knives are fixed on the left side and the right side under a material loading trolley, the sealing grooves are arranged at positions corresponding to the sand knives on annealing furnace walls, sand is disposed inside the sealing grooves, at least two layers of sand knives and at least two layers of corresponding sealing grooves are disposed on the left side and the right side of the sealing structure, and the sand knives are inserted into the sand of the corresponding sealing grooves. By adding one layer on an original furnace gas sealing structure, the furnace gas sealing structure is capable of effectively improving furnace gas sealing effect, greatly prolonging service lives of bearing blocks and bearings, and is the ideal furnace gas sealing structure of a continuous annealing furnace. The continuous annealing furnace consists of the furnace gas sealing structure.
Description
Technical field
The utility model relates to a kind of casting industry continuous annealing furnace structure, particularly continuous annealing furnace furnace gas sealed structure and uses the continuous annealing furnace of sealing structure.
Background technology
Annealing is to eliminate the most reliable, the effective and timesaving method of casting stress, and casting industry general continuous annealing furnace that adopts when the foundry goods of producing in enormous quantities carries out anneal to foundry goods.Existing furnace gas sealed structure is such: each fixes a sand cutter about below the charging chassis, each fixes a sealing groove annealing furnace furnace wall correspondence position, fill sand in the sealing groove, the sand cutter inserts in the sealing groove to stop the high-temperature furnace gas that blows from slit between charging chassis and the body of heater.Find in the implementation process that single sealed structure like this can not stop furnace gas fully, make continuous annealing furnace furnace gas sealed structure effect not ideal, still have more furnace gas to blow to bearing support and bearing by sealed structure, the hot blast effect of high-temperature furnace gas significantly reduces the work-ing life of bearing support and bearing.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of furnace gas good sealing effect, continuous annealing furnace furnace gas sealed structure that prolongs continuous annealing furnace bearing support and bearing work-ing life and the continuous annealing furnace that uses the sealing structure.
The utility model continuous annealing furnace furnace gas sealed structure is as follows: comprise sealing groove and sand cutter, the sand cutter be fixed on the charging chassis below the left side and the right side, the position of the corresponding sand cutter in annealing furnace furnace wall is provided with sealing groove, place sand in the sealing groove, sand cutter that left side and right side are provided with and corresponding sealing groove are provided with two-layer respectively at least, and the sand cutter inserts in the sand of corresponding sealing groove to stop from the high-temperature furnace gas that the slit blows between chassis and the body of heater of feeding.
In the utility model continuous annealing furnace furnace gas sealed structure, sealing groove and sand cutter can adopt suitable structure, and in the two-layer at least sealing groove and sand cutter of every side, two-layer or two-layer above sealing groove and sand cutter can be horizontal, also can arrange by ladder.
The utility model continuous annealing furnace comprises heating furnace body and charging chassis, and wherein, two-layer at least sealing groove is arranged on the heating furnace body, and two-layer at least sand cutter is arranged on the charging chassis.
In the utility model continuous annealing furnace furnace gas sealed structure, on the basis of former furnace gas sealed structure, increase one or more layers, can more effectively stop passing through of furnace gas, improved sealing effectiveness effectively, experiment shows that the furnace gas sealed structure result of use after the improvement is good, the work-ing life of having improved bearing support and bearing greatly.The utility model device is simple, practical, can be extensive use of.
Description of drawings
Fig. 1 is the one-piece construction sectional view of the utility model continuous annealing furnace.
Fig. 2 is existing furnace gas sealed structure front view.
Fig. 3 is the utility model furnace gas sealed structure front view.
Structure is among the figure: 1-heating furnace body, 2-well heater guard shield, 3-well heater, 4-hot air circulation blower, 5-wheel cooling quench pipe, 6-bearing support and bearing, the 7-chassis of feeding, 8-one deck sealing groove, 9-one deck sand cutter, two layers of sealing groove of 10-, two layers of sand cutter of 11-.
Embodiment
Further specify the effect of the utility model furnace gas sealed structure below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 3, comprise that the continuous annealing furnace of the utility model furnace gas sealed structure comprises heating furnace body 1, well heater guard shield 2, well heater 3, hot air circulation blower 4, wheel cooling quench pipe 5, bearing support and bearing 6, charging chassis 7, one deck sealing groove 8,9, two layers of sealing groove 10 of one deck sand cutter, two layers of sand cutter 11 wherein remove other block construction of furnace gas sealed structure and the technology contents that mutual relationship can adopt this area routine.The furnace gas sealed structure adopts double-deck furnace gas sealed structure, comprises that specifically one deck sealing groove of being fixed on the furnace wall 8, two layers of sealing groove 10 and one deck sand cutter 9 and 11, two layers of sealed structure of two layers of sand cutter of being fixed on the charging chassis adopt stepped arrangement.
Compare with existing sealed structure, increased one deck sealed structure, be inserted in one deck sealing groove 8 of filling sand of being fixed on the furnace wall and the two layers of sealing groove 10 with one deck sand cutter 9 of charging trolley movement and two layers of sand cutter 11.Two-layer sealed structure reaches more reliable furnace gas sealing effectiveness, improves the reliability of continuous annealing furnace furnace gas sealing, thereby reduces the infringement of high-temperature furnace gas to bearing support and bearing, prolongs the work-ing life of bearing support and bearing.
When the utility model continuous annealing furnace uses, stack foundry goods on the charging chassis, when carrying out anneal, high-temperature furnace gas can blow to bearing and bearing support direction along the gap between charging chassis and the return of goods furnace wall, after the furnace gas sealed structure is installed, at first because the barrier effect of the first layer sand cutter and sealing groove, most furnace gas can be blocked, and the sealed structure of the second layer can stop remaining furnace gas substantially, like this by two-layer sealed structure, can stop more effectively that furnace gas blows to bearing and bearing support, its reliability is big, and is practical, and improvement cost is low, be a kind of major progress of furnace gas sealed structure, the work-ing life of having improved bearing and bearing support greatly.
