Description
Technical field
The utility model belongs to coking equipment, is a kind of coke oven coal leveling device.
Technical background
Traditional coke oven is all generally coal leveling device of coalingging at top is exactly simple coal leveling bar, and flat coal mode utilizes the tangential movement back and forth of coal leveling bar to drive scraper plate to be evened up by the coal loaded in coking chamber simply, and unnecessary ribbing is gone out coking chamber.There is following many deficiencies in the coke oven of prior art: one is that cause top coke not fine and close, pore is many, and crackle is many, frangible, and most of coke is coke breeze state, of poor quality, affects the Integral lifting of coke quality because coking chamber superjacent loosens; Two is coke that coking chamber top is formed, and after the discharging of the coke, major part becomes coke powder or nut coke, and cause valuable metallurgical coke output on the low side, metallurgical coke rate is not high, causes production efficiency low; Three is that after flat coal, remaining coal amount is many, and affect single furnace operating time, the homogeneity of coke oven coal-charging pushing operation is bad, causes rhythm of production poor stability.
Utility model content
The utility model aims to provide a kind of coke oven coal leveling device overcoming above-mentioned prior art weak point, utilizes gravity and rolling principle, coal charge can be compressed layer by layer, flatten.
The utility model is achieved through the following technical solutions:
Coke oven coal leveling device, comprises trailing wheel, rear lever, lever shaft, backstay, front lever, front-wheel, ramp, coal leveling bar.Front-wheel and trailing wheel are one in front and one in back arranged on the centre of coal leveling bar two end plates.Rear lever tail end link trailing wheel, front lever front end link front-wheel, the middle part of front lever and rear lever is each passed through front lever shaft and rear lever shaft is fixed on the end plate of coal leveling bar.Four backstays are linked on the end plate of coal leveling bar respectively, and wherein two are separately positioned on the rear and front end of rear lever shaft, a little higher than rear lever shaft in position; Other two rear and front ends being separately positioned on front lever shaft, a little higher than front lever shaft in position.Ramp is arranged on the below of coal leveling bar, and ramp is domatic with two gentle gradient.Ramp is arranged on the below of coal leveling bar, and ramp is domatic with two gentle gradient.
The beneficial effects of the utility model: complete assembly can free in and out coking chamber with coal leveling bar, enter into coking chamber rear roller height can automatically decline, by the back and forth rolling of roller at coal seam upper epidermis, coal charge tegillum lamination is tight, pressing, thus increases the degree of compactness of coal charge.Improve for existing coke oven coal-charging flat coal method limitation, do not needing to change coke oven construction, do not need to change rhythm of production, when not needing too many investment, can play the throughput of existing coke oven to greatest extent, increase yield, improves quality.
Accompanying drawing explanation
Fig. 1 is coke oven coal leveling device structure schematic front view.
Fig. 2 is coke oven coal leveling device structure schematic side view.
Fig. 3 is coke oven coal leveling device structure schematic top plan view.
In figure: 1-trailing wheel, lever after 2-, lever shaft after 3-, lever before 4-backstay one, 5-, 6-front-wheel, 7-ramp, 8-coal leveling bar, lever shaft before 9-, 10-backstay two, 11-backstay three, 12-backstay four.
Embodiment
Content of the present utility model is further illustrated below in conjunction with accompanying drawing embodiment:
Coke oven coal leveling device, comprises by 1-trailing wheel, lever after 2-, lever shaft after 3-, lever before 4-backstay one, 5-, 6-front-wheel, 7-ramp, 8-coal leveling bar, lever shaft before 9-, and 10-backstay two, 11-backstay three, 12-backstay four forms.6-front-wheel and 1-trailing wheel are one in front and one in back arranged on the centre of 8-coal leveling bar two end plates; Lever tail end link 1-trailing wheel after 2-, lever front end link 6-front-wheel before 5-, before 5-, after lever and 2-, the middle part of lever to be each passed through before 9-lever shaft after lever shaft and 3-, and two regulations and parameters axles are all fixed on the end plate of 8-coal leveling bar; 4-backstay one and 10-backstay two are separately positioned on the rear and front end of lever shaft after 3-, lever shaft after a little higher than 3-in position, 11-backstay three and 12-backstay four are separately positioned on the rear and front end of lever shaft before 9-, lever shaft before a little higher than 9-in position, four backstays are linked on the end plate of 8-coal leveling bar respectively; 7-ramp is arranged on the below of 8-coal leveling bar, and 7-ramp is domatic with two gentle gradient.
Operating process:
Before entering the flat coal of coke furnace carbonization chamber: 8-coal leveling bar advances to the little fire door of coking chamber, when 6-front-wheel be advanced to 7-ramp domatic after, along the domatic orbiting motion of 7-ramp, lever lever shaft heaving and dipping before 9-before drive 5-simultaneously, then be after 1-trailing wheel is advanced to 7-ramp, equally along the domatic orbiting motion of 7-ramp, lever lever shaft heaving and dipping after 3-after drive 2-simultaneously, in the lifting of 1-trailing wheel, in translation motion, after 2-, the other end of lever will produce reversing motion by leverage, downward pressure can be produced to the upper rear end of lever before 5-simultaneously, before 5-, the 6-front-wheel of the front end of lever is under the effect of lever, progressively obtain lifting, and remain on a certain height, until 6-front-wheel freely can enter into coke furnace carbonization chamber inside from the little fire door of coke oven, now 1-trailing wheel falls along another domatic beginning of 7-ramp, after 2-, the other end of lever starts lifting, depart from the compressing to lever before 5-, 6-front-wheel starts to fall, height of drop is subject to the control of 10-backstay two, produce with coal seam and contact.After 2-, lever two ends height is advisable not exceed 8-coal leveling bar end plate lower edges, is controlled, guarantee that it can free in and out the little fire door of coke oven, not scratching by 4-backstay one and 10-backstay two.
Enter coke furnace carbonization chamber, flat coal operation: when the coal seam of coke furnace carbonization chamber is attached to the height of drop with 6-front-wheel or 1-trailing wheel, this device just can play flat coal effect of rolling, 8-coal leveling bar drives 1-trailing wheel and 6-front-wheel to need to carry out repeatedly to-and-fro movement on coal seam, in order to prevent two levers unfettered and arbitrarily convert inclination angle, cause coal leveling bar running resistance excessive, and damage equipment or can not normal flat coal operation, by 11-backstay three, 12-backstay four and 4-backstay one, 10-backstay two controls the inclination angle of lever after lever before 5-and 2-respectively, remain that the inclination angle of two levers is no more than 45 degree.
Exit coke furnace carbonization chamber, stop flat coal: be contrary with the process entering coke furnace carbonization chamber.
