Abstract
The utility model discloses a smoke sealing device which has the key points as follows: the device comprises an adjustable sealing connecting piece (2a) which is arranged at a joint of a smoke hood (2) and a water cooling conveying trough (1) and at the outer side of the smoke hood (2), wherein the adjustable sealing connecting piece (2a) is connected with a sealing cover plate (3); the side wall of the water cooling conveying trough (1) extends downwards after extending obliquely and upwards to form a flanging structure (1a); the flanging structure (1a) is provided with a friction plate (1b) overlapped joint with the inner side at the lower part of the sealing cover plate (3); and a water cooling channel is arranged above or below the adjustable sealing connecting piece (2a). A narrow gap is arranged between the adjustable sealing connecting piece (2a) and the adjustable sealing connecting piece (2a), and air holes are arranged in the sealing cover plate (3). The smoke sealing device has good sealing and cooling effects and effects such as environment friendliness, energy saving, convenience in maintenance and the like and is a new energy-saving and environment friendly technology with a popularization value for a continuous charging process of an electric furnace or other charging processes.
Description
Technical field
The utility model relates to a kind of tightness system, relates in particular in a kind of waste steel for electric furnace charging system movable water-cooled and carries the flue gas negative-pressure sealing device between hopper and static petticoat pipe.
Background technology
The steel scrap continuous charging is the important energy-conserving and environment-protective subitem technology of of Electric furnace steel making; And the sealing in the waste steel for electric furnace continuous charging system is particularly important; Guarantee the sealing of each link in the steel scrap continuous charging passage; Avoiding air admission steel scrap transfer passage is the technological difficulties that must solve, and particularly carries between the static petticoat pipe of hopper box how to keep sealing a urgent problem that becomes the technician for movable water-cooled.
The utility model content
The purpose of the utility model provides a kind of movable water-cooled and carries the flue gas tightness system between hopper and the static petticoat pipe.
To achieve these goals; Adopt following technical scheme: a kind of flue gas tightness system; It is characterized in that: said device comprises and is arranged on the adjustable seal connector that petticoat pipe and water-cooled are carried hopper joining place, the petticoat pipe outside, and adjustable seal connector is connected with seal cover board, and water-cooled is carried limit wall extension downwards again after oblique upper stretches out of hopper; Form turnup structure, turnup structure is provided with the friction plate that overlaps mutually with the seal cover board lower inside.
As further optimization, for adjustable seal connector is lowered the temperature, prolong its work-ing life, be provided with water-cooling channel above or below the said adjustable seal connector.
As further optimization, in order to prevent seal cover board, have narrow slot between said adjustable seal connector and the turnup structure, have breather hole on the seal cover board.
The sealing device has sealing, cooling property is good, and it is convenient to safeguard, environmental protection, effect such as energy-conservation; Make water-cooled carry the cavity between hopper and petticoat pipe to form confined chamber; Avoid wild wind to sneak in the material transfer passage, water flowing cooling in water-cooling channel simultaneously, the work-ing life of assurance equipment.
Description of drawings
Fig. 1 is that the utility model is carried the structural representation that is provided with between hopper and the petticoat pipe in water-cooled;
Fig. 2 is the partial enlarged drawing of A among Fig. 1.
Among the figure, part 1 is carried hopper for water-cooled, and part 1a is a turnup structure, and part 1b is a friction plate, and part 2 is a petticoat pipe, and part 2a is adjustable seal connector, and part 3 is a seal cover board, and part 4 is a material.
Embodiment
As depicted in figs. 1 and 2, on the turnup structure 1a of water-cooled conveying hopper 1 friction plate 1b is installed, friction plate 1b and seal cover board 3 overlap joints; When water-cooled is carried hopper 1 relative petticoat pipe 2 vibrations or is slided; Friction plate 1b and the relative slippage of seal cover board 3 faying surfaces, petticoat pipe 2 is equipped with adjustable seal connector 2a, and adjustable seal connector 2a connects with seal cover board 3; Adjustable seal connector 2a surrounds a seal channel; But water flowing cooling, and and turnup structure 1a between form narrow slot, the breather hole that has on the seal cover board 3; Little air is inhaled in the negative pressure transportation passage through transferring seal connector 2a and turnup structure 1a to constitute narrow slot, prevents that seal cover board 3 is overheated.
In this device, water-cooled is carried the turnup structure 1a and the friction plate 1b of hopper, petticoat pipe 2 and adjustable seal connector 2a, and the connection that adjustable seal connector 2a and seal cover board are 3 all is detachable connections, is convenient to safeguard and change.
In addition, the coupled position of petticoat pipe 2 and adjustable seal connector 2a is adjustable up and down, carries the annular seal space volume of hopper 1 both sides thereby can adjust petticoat pipe 2 with water-cooled.
The utlity model has sealing, cooling property is good, it is convenient to safeguard, environmental protection, effect such as energy-conservation are the new technologies that on electric furnace continuous charging or other charging technology, has promotional value.
Claims (3)
1. flue gas tightness system; It is characterized in that: said device comprises that being arranged on petticoat pipe (2) carries the adjustable seal connector (2a) in hopper (1) joining place, petticoat pipe (2) outside with water-cooled; Adjustable seal connector (2a) is connected with seal cover board (3); Water-cooled carries the limit wall of hopper (1) after oblique upper stretches out, to extend again downwards, forms turnup structure (1a), and turnup structure (1a) is provided with the friction plate (1b) that overlaps mutually with seal cover board (3) lower inside.
2. flue gas tightness system as claimed in claim 1 is characterized in that: be provided with water-cooling channel above or below the said adjustable seal connector (2a).
