Description

Technical Field

[0001] The invention relates to the technical field of coke ovens, and in particular to a coke oven chute opening regulating structure. Background Art

[0002] The coke oven body is mainly composed of carbonization chamber, combustion chamber, heat storage chamber, ramp and furnace top area. The ramp is located at the upper part of the heat storage chamber and the lower part of the combustion chamber. It is a passage connecting the heat storage chamber and the combustion chamber. The air and gas in the heat storage chamber enter the vertical fire channel of the combustion chamber through the ramp for combustion.

[0003] The reheating coke oven can be heated by high calorific value coke oven gas, low calorific value blast furnace gas or mixed gas. When heated by coke oven gas, the two regenerators corresponding to the same combustion chamber are fed with combustion-supporting air at the same time; when heated by blast furnace gas, one regenerator is fed with combustion-supporting air and the other with blast furnace gas. In the actual production process, when it is necessary to switch the gas heating method, the gas flow path inside the coke oven changes, and accordingly, the suction and pressure at various locations will change. At this time, the internal pressure and gas flow of the coke oven can be adjusted by changing the opening of the inclined channel at the bottom of the vertical fire channel or changing its opening and closing state.

[0004] The adjustment accuracy of the cross-sectional area of ​​the airflow channel at the chute of the coke oven is directly related to the quality of coke maturation. At present, most of the methods use hooks to increase or decrease the adjustment bricks to roughly change the cross-sectional area of ​​the airflow channel at the chute, and then change the heating gas flow and heating system. The disadvantage is that the gas flow cannot be accurately and quantitatively adjusted, so the heating system is difficult to meet the design requirements, affecting the normal production of the coke oven. Summary of the invention

[0005] The present invention provides a coke oven chute opening regulating structure, which is provided with flippable regulating bricks, and an regulating tool is inserted into a fire hole above a self-supporting fire channel, and the position state of the regulating bricks is changed by utilizing the seesaw principle, thereby accurately regulating the cross-sectional area of ​​the airflow channel and the gas flow rate of the chute opening, maintaining the coke oven heating system, and ensuring stable production.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A coke oven chute adjustment structure comprises an adjustment brick and an adjustment brick groove; the adjustment brick groove is arranged on one side or both sides of the chute opening, the adjustment brick groove is an inclined groove matched with the adjustment brick, and the groove bottom away from one end of the chute opening is inclined toward the inner and lower part of the masonry at the top of the chute opening, and an upwardly protruding fulcrum beam is arranged between the adjustment brick groove and the chute opening; the middle part of the adjustment brick is supported on the fulcrum beam and can rotate around the fulcrum beam; when the chute opening is adjusted, the operation is performed by an adjustment tool extending from a fire hole above a corresponding vertical fire channel, and according to needs, the adjustment tool is used to press one end of the adjustment brick corresponding to the chute opening or one end of the corresponding adjustment brick groove, and the adjustment brick will rotate around the fulcrum beam, and when the corresponding end of the adjustment brick falls into the adjustment brick groove, the other end is lifted, and the chute opening is in an open state; when the corresponding end of the adjustment brick falls above the chute opening, the chute opening can be covered.

[0008] The adjusting brick is a rectangular parallelepiped structure; the length of the adjusting brick is greater than twice the length of the inclined road opening in the corresponding direction, and the distance between the bottom end of the adjusting brick groove and the highest point of the fulcrum beam is 1 / 2 of the length of the adjusting brick in the corresponding direction.

[0009] The cross section of the fulcrum beam is in an arc shape, and the corresponding end smoothly transitions to the bottom surface of the adjusting brick groove; the fulcrum beam and the top masonry of the inclined opening at the corresponding position are an integrated structure.

[0010] The top of the adjusting brick is provided with an inclined groove 1 at one end corresponding to the inclined passage, and an inclined groove 2 is provided at one end corresponding to the adjusting brick groove; the inclined groove 1 and the inclined groove 2 are symmetrically arranged, and the groove depth near one end of the adjusting brick outer edge is greater than the groove depth near the middle of the adjusting brick.

[0011] The bottom surfaces of the first oblique groove and the second oblique groove are flat surfaces or downwardly curved arc surfaces.

[0012] The width of the adjusting brick groove is the width of the adjusting brick + (2-10) mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) Simple structure, easy to implement, convenient to operate, and obvious effect;

[0015] 2) The opening and closing of the inclined channel is changed by applying force to flip the adjusting brick using the adjusting tool, which changes the inconvenience of hooking the adjusting brick in the traditional adjustment method. The cross-sectional area of ​​the gas flow at the inclined channel of the coke oven can be changed quickly and accurately, thereby achieving the purpose of adjusting the gas flow at the inclined channel and the coke oven pressure, and maintaining the stability of the coke oven heating system and production.
