Abstract

The utility model relates to a circular cooler afterheat recycling and sealing device, which comprises a sealing cover. The circular cooler afterheat recycling and sealing device is characterized in that the lower portion of the sealing cover is equipped with a sealing frame, a fixing hinged shaft is arranged on the sealing frame, the lower portion of the sealing frame is equipped with a sealing water mixing tank limiting frame, the bottom portion of the sealing frame is equipped with a sealing oblique plate, a sealing water mixing tank is arranged between the sealing water mixing tank limiting frame and the sealing oblique plate, the upper portion of the sealing water mixing tank is hinged with the fixing hinged shaft through a hinged shaft and a connecting rod, the lower portion of the sealing water mixing tank contacts with an upper surface of a trolley retaining plate, a sealing dropping rod is arranged on the sealing oblique plate, and a spring is arranged between the sealing frame and the sealing water mixing tank. The circular cooler afterheat recycling and sealing device has the advantages that the circular cooler afterheat recycling and sealing device is simple in structure, simple and convenient in mounting and maintenance, fine in sealing effect, stable in afterheat boiler steam quantity and long in service life, can increase temperature of waste gas, increases afterheat recycling efficiency, and is particularly adaptable to afterheat power generation of circular coolers.

Description

Ring cold machine residual heat recovery and sealing device
Technical field
The utility model relates to the central cooler apparatus field, relates in particular to a kind of ring cold machine residual heat recovery and sealing device.
Background technology
In the central cooler equipment that metallurgy industry uses, the cold wind process circular cooler trolley grate plate heat of cooling sintering deposit that air blast blasts from bellows, about 350 ℃ of cooled EGTs, this waste gas is recyclable to produce steam by waste heat boiler, can directly utilize or cogeneration.Ring cold machine residual heat recovery and sealing device directly influences the efficient of waste heat recovery.
Prior art is that the chassis sideboard with central cooler is covered by seal closure, and a steel plate seal is established in the bottom of seal closure, keeps less clearance with chassis sideboard end face.Perhaps rubber slab is established in the bottom of seal closure, and the rubber slab bottom contacts with chassis sideboard end face.Because the chassis sideboard moves, the steel plate seal can not directly contact with chassis sideboard end face, and it is bigger to leak out.Though can contact with chassis sideboard end face with rubber gasket sheet and since the sealing case temperature up to 350 ℃ about, make the sealing effectiveness variation after rubber slab is aging.Cause waste heat recovery efficient to reduce, big to the steam undulate quantity that waste heat boiler is produced, do not satisfy cogeneration and require quantity of steam needs stably.
Summary of the invention
The utility model purpose is to solve the deficiencies in the prior art, provides a kind of simple in structure, good sealing effect, can improve EGT, the waste heat boiler quantity of steam is stable, improves waste heat recovery efficient, installation and maintenance are simple and convenient, the ring cold machine residual heat recovery and sealing device of long service life.
The technical solution of the utility model is achieved in that
According to ring cold machine residual heat recovery and sealing device of the present utility model, comprise seal closure, it is characterized in that being provided with seal frame in the bottom of seal closure, fixedly cardan axle is installed on the described seal frame, be provided with sealing string water tank position-limited rack in the seal frame bottom, be provided with the sealing swash plate in the bottom of seal frame, sealing string water tank is arranged between sealing string water tank position-limited rack and the sealing swash plate, the top of described sealing string water tank is by cardan axle and connecting rod and fixedly cardan axle is hinged, the bottom of sealing string water tank with contact above the chassis sideboard, the sealing rod that falls is provided with and seals on the swash plate.
The utility model is provided with spring between described seal frame and sealing string water tank.
The utility model has the advantages that:
Simple in structure, convenient for installation and maintenance, good sealing effect, the waste heat boiler quantity of steam is stable, can improve EGT, improves waste heat recovery efficient, and installation and maintenance are simple and convenient, and long service life is specially adapted to encircle cold boiler cogeneration.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cut-away view of Fig. 1.
The specific embodiment
As Fig. 1-shown in Figure 2,
Ring cold machine residual heat recovery and sealing device of the present utility model comprises seal closure 1, it is characterized in that being provided with seal frame 3 in the bottom of seal closure 1, and seal closure 1 and the connected mode of seal frame can be that bolt is connected also can be welding.
Fixedly cardan axle 4 is installed on the described seal frame 3, be provided with sealing string water tank position-limited rack 8 in seal frame 3 bottoms, be provided with sealing swash plate 10 in the bottom of seal frame 3, sealing string water tank 7 is arranged between sealing string water tank position-limited rack 8 and the sealing swash plate 10, the top of described sealing string water tank 7 is by cardan axle 6 and connecting rod 5 and fixedly cardan axle 4 is hinged, the bottom of sealing string water tank 7 with 10 contact above the chassis sideboard, sealing falls and excellent 2 is provided with and seals on the swash plate 10.The setting of its string water tank position-limited rack 9 has limited the moving to the both sides string of sealing string water tank 7 effectively; The utility model seals rod 2 and is provided with, and has sealed the gap between string water tank 7 and the sealing swash plate 10 effectively, has reached good sealing effectiveness;
The utility model is provided with spring between described seal frame 3 and sealing string water tank 7.The effect of its spring is to alleviate string water tank 7 and the friction between 10 above the chassis sideboard.
