Embodiment
Embodiment 1
Can be known to embodiment 1 shown in Figure 3 by Fig. 1: the excessive tightness system of flue gas when preventing tamping coke oven coal-charging comprises the housing 1 of bottom surface opening; In the said housing 1 is the flue gas cushion chamber; Be respectively equipped with Qianmen 5 and back door 7 in the front and rear end of said housing 1; Said Qianmen 5 is suitable with the fire door of said tamping coke furnace; 5 both sides and upper edge are respectively equipped with sealing knife-edge 4 at the Qianmen, are respectively equipped with soft 6 of resistant to elevated temperatures sealing in left and right two edges and the upper edge at said back door 7; The middle part in the outside of said flue gas cushion chamber and arranged on left and right sides wall be respectively equipped with coal charger on the suitable guide deflection sheave 2 of guide rail; The bottom in the outside of and arranged on left and right sides wall is respectively equipped with distortion-free armful of rail wheel 3 at said flue gas cushion chamber rear portion.Said flue gas cushion chamber is made up of front chamber 8, rear chamber 10 and the transition chamber thereof between forward and backward chamber 9; The shape of cross section of said front chamber 8 and rear chamber 10 is a rectangle, and the shape of cross section of said transition chamber thereof 9 is trapezoidal, and the width of said front chamber 8 is less than the width of rear chamber 10, and the height of said front chamber 8, transition chamber thereof 9 and rear chamber 10 equates; Said guide deflection sheave 2 and armful rail wheel 3 lay respectively at the outside of the and arranged on left and right sides wall of said rear chamber 10; Said guide deflection sheave 2 is two pairs, and two pairs of guide deflection sheaves 2 are arranged above and below.
This device is installed in side coal car coal groove the place ahead, adopts the hydraulic power operation.Before the side coal car is coaling, make this device proceed to the tamping coke furnace fire door through two oil cylinders on the side coal car, installing before, move forward through the pressure relay automatic stop again and make the Qianmen 5 of this device contact with the fire door of tamping coke furnace.The width at the Qianmen 5 of this device and highly all greater than said tamping coke furnace fire door, so the peripheral portion of the firedoor frame of peripheral sealing knife-edge 4 in Qianmen 5 and tamping coke furnace closely contacts, and prevents that flue gas is excessive.The Qianmen 5 of this device with just begin after the tamping coke furnace fire door contacts to tamping coke oven coal-charging.Briquette be shaped as rectangular parallelepiped, briquette at first gets into the flue gas buffer chamber through back door 7, is transported to Qianmen 5 by fortune coal track then, gets in the tamping coke furnace through coke oven door at last.The height of briquette and width are less than the height and the width at said Qianmen 5, and like this, briquette could pass through smoothly.
Adopt 4 sealings of sealing knife-edge between said housing 1 and the tamping coke furnace fire door, said sealing knife-edge 4 compresses and is sealed on the firedoor frame, just can prevent to tamping coke oven coal-charging the time that like this flue gas is excessive, can not pollute air.
After the oven door opening of tamping coke furnace, it is unstable that the flue gas atmospheric pressure in the stove also becomes, and can overflow tamping coke furnace; Because firedoor frame is tightly connected with this device; The flue gas that overflows can not overflow outdoor, but the flue gas cushion chamber that gets in the housing 1 cushions, and soft 6 of left and right two edges at said back door 7 and the sealing of upper edge cooperate with the briquette outline; Guarantee that the flue gas in the flue gas cushion chamber can be not excessive yet, the flue gas in the last flue gas cushion chamber can be drawn back in the stove.Like this; This device has solved when fiddling with coke oven coal-charging the excessive problem of flue gas in the coke oven with regard to good; Prevent that negative pressure is crossed the hidden danger that senior general's outside air sucks tamping coke furnace and then the blast of generation coke oven in the coke oven, neither can produce atmospheric pollution, the safety when having guaranteed again to coaling.Distance between soft 6 of the sealing at left and right two edges at said back door 7 should be less than the width of briquette; The height of soft 6 lower edge of the sealing on the upper edge at back door 7 should be less than the height of briquette, and the outline of soft 6 ability of said like this sealing and briquette cooperates the prevention flue gas excessive.
In the process of coalingging, left and right two edges at said back door 7 and soft 6 of the sealing of upper edge not only can stop flue gas excessive, and because material is softer, also can destroy the briquette form generation and make impaired the coming off of briquette in moving ahead.
Two pairs of guide rails that coal charger is provided with and is arranged above and below, is provided with in opposite directions, last row's guide rail is directed downwards, and following row's guide rail direction is upwards.Guide deflection sheave 2 on this device is two couple for being arranged above and below also, and the guide rail of arranging on top a pair of guide deflection sheave 2 and the coal charger is slidingly matched, and following a pair of guide deflection sheave 2 is slidingly matched with the guide rail of arranging down.2 pairs of these devices of last row's guide rail and guide deflection sheave produce downward pressure, prevent that it from turning forward; 2 pairs of these devices of following row's guide rail and guide deflection sheave play a part to support.Like this, this device just can smooth running.
Be located at the and arranged on left and right sides wall that rail wheel 3 can be held housing 1 dynamically of embracing of said housing 1 bottom, this device of coal charger rear deflector door scratching damage when causing coalingging to internal strain is heated after preventing housing 1 and fire door contacting.Restriction is embraced the track of rail wheel 3 and is located at the inboard of embracing rail wheel 3, prevents to embrace rail wheel 3 and comes closer.
The height of said front chamber 8, transition chamber thereof 9 and rear chamber 10 also can be unequal, and the top of front chamber 8, transition chamber thereof 9 and rear chamber 10 can raise gradually, makes the capacity of flue gas cushion chamber become big, more helps storing excessive flue gas to the flue gas cushion chamber.
Can be known by embodiment shown in Figure 42: different with embodiment 1 is that said flue gas cushion chamber is made up of front chamber 11 and rear chamber 12; The shape of cross section of said front chamber 11 is a rectangle, and the shape of cross section of said rear chamber 12 is semicircle, and said semicircular radius is greater than the width of front chamber 11; The height of said front chamber 11 and rear chamber 12 equates.The height of said front chamber 11 and rear chamber 12 also can be unequal, and the top of front chamber 11 and rear chamber 12 can raise gradually, makes the capacity of flue gas cushion chamber become big, more helps storing excessive flue gas to the flue gas cushion chamber.
The lines of the outer side wall of the housing of this device can be straight line, also can be curve.Can process according to practical situation.As long as internal structure and mode of connection meet the ultimate principle of this device.
