Description

Technical Field

[0001] The invention relates to the technical field of environmental protection in coking production, and in particular to a device specially used for cleaning graphite in a coke oven carbonization chamber. Background Art

[0002] Since coal is a mixture of multiple chemical elements, and the temperature of coal during high-temperature carbonization in the coke oven varies with the different stages of coking, it is currently believed that carbon deposits in the carbonization chamber are formed by the gradual accumulation of free carbon generated by the pyrolysis of raw coal gas. We know that amorphous carbon (including coal and coke) will form carbon deposits at temperatures above 2000°C, while the carbonization chamber temperature of a coke oven usually does not exceed 1200°C, and the furnace top space of the carbonization chamber does not exceed 850°C. Therefore, the most direct factor in the formation of carbon deposits is excessively high carbonization chamber temperature.

[0003] To prevent carbon deposition in the carbonization chamber, all kinds of excessively high temperatures in the coke oven must be strictly avoided. The most important one is the temperature of the furnace top space, because the furnace top space is the only way for the raw gas to enter the gas collecting pipe. If the temperature of the furnace top space is too high, it will directly lead to the acceleration of carbon deposition. Therefore, we stipulate that the temperature of the carbonization chamber top space is ≤830℃ at the end of coking.

[0004] Secondly, leakage in the carbonization chamber is also a major cause of incomplete combustion of raw gas, leading to carbon deposits. Therefore, timely repair of carbonization chamber leaks is extremely important during daily production. Furthermore, since the coke oven may need to be shut down for a short period of time during production, it is necessary to promptly lower the temperature of the mature coke. These are all important preventative measures for carbon deposits, but these measures can only slow the rate of carbon deposit formation. Carbon deposits on both sides of the carbonization chamber are inevitable in the middle and later stages of the coke oven.

[0005] With the gradual increase in environmental pressure, the unorganized smoke emissions during the coke oven production process must be effectively controlled. When a large amount of carbon deposits are generated on the top and wall of the carbonization chamber, it is very easy for raw coal gas to escape from the carbonization chamber during the coal adding process. The carbon deposits on the wall of the furnace can easily affect the coal adding and cause coal collapse, thereby affecting the coke production.

[0006] Carbon deposits on the top of the coke oven carbonization chamber reduce the space above the coal cakes, reducing the suction force of the raw gas introduced into the gas collection pipe during the coal charging process. This makes the raw gas easily dissipate into the atmosphere, which not only affects the safety and environment of the production area but also causes resource waste. Therefore, the present invention proposes a device specifically for cleaning graphite in the coke oven carbonization chamber. Summary of the Invention

[0007] The object of the present invention is to provide a device specifically for cleaning graphite in the carbonization chamber of a coke oven in order to solve the above problems.

[0008] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0009] A device specially used for cleaning graphite in the carbonization chamber of a coke oven, comprising a coke pusher, a base fixed on the back wall of the coke pusher, side plates installed on both sides of the upper end of the base, a fixed seat provided on the back wall of the side plate, a through hole provided on the fixed seat, a connecting shaft provided in the through hole, convex rings fixed at both ends of the connecting shaft, a locking plate fixed on one side wall of the connecting shaft, circular holes provided on the inner walls of the side plates, a fixed shaft installed in the circular holes, a cleaner provided between the fixed shafts, a locking cavity provided at the bottom end of one side wall of the cleaner, and the locking plate and the locking cavity having the same specifications.

[0010] Furthermore, the base is fixed to the coke pushing palm by four sets of bolts, the base is made of high manganese steel, and the bolts are high-strength bolts.

[0011] By adopting the above technical solution, the coke pushing palm is fixed on the coke pushing vehicle, and the coke pushing vehicle can drive the cleaner on the coke pushing palm to move.

[0012] Furthermore, the side panels are welded to the base, and the fixing seats are welded to the side panels.

[0013] By adopting the above technical solution, the side plate provides an installation position for the cleaner, and the fixing seat provides an installation position for the connecting shaft.

[0014] Furthermore, the through hole is formed on the fixing seat, the connecting shaft passes through the through hole, the convex ring is welded to the connecting shaft, the outer diameter of the convex ring is larger than the inner diameter of the through hole, and the material of the convex ring is high manganese steel.

[0015] By adopting the above technical solution, the convex ring limits the connecting shaft, and the connecting shaft can drive the locking plate to rotate.

[0016] Furthermore, the locking plate is welded to the connecting shaft, and the locking plate forms an angle of 45 degrees with the connecting shaft.

[0017] By adopting the above technical solution, the locking plate serves as a safety lock, and when the cleaner is not in use, the safety lock fixes the cleaner through the position difference with the cleaner.

[0018] Furthermore, the locking plate is a strip-shaped structure and is made of high manganese steel.

[0019] By adopting the above technical solution, the high manganese steel material can improve the high temperature resistance of the locking plate.

[0020] Furthermore, the circular hole is formed on the side plate, and the depth of the circular hole is 50 mm.

[0021] By adopting the above technical solution, the circular hole provides an installation space for the fixed shaft.

[0022] Furthermore, the fixed shaft is rotatably connected to the circular hole, and the fixed shaft is welded to the cleaner.

[0023] By adopting the above technical solution, the fixed shaft can fix the cleaner and drive it to flip over at the same time.

[0024] Furthermore, the cleaner is made of high manganese steel and has a thickness of 30 mm.

[0025] By adopting the above technical solution, the cleaner moves under the drive of the coke pushing palm, and starts to cut the coke deposits condensed on the furnace top in the carbonization chamber. The cut coke deposits are directly burned at high temperature in the carbonization chamber.

[0026] Furthermore, the locking cavity is formed on the cleaner.

[0027] By adopting the above technical solution, the locking plate is combined with the locking cavity to fix the cleaner when it is not in use.

[0028] The specific working principle is as follows: since the cleaner is fixed on the upper back side of the coke pushing palm, after the coke pushing car completes pushing the coke and the coke side furnace door is sealed, the coke pushing palm exits the carbonization chamber, the safety lock on the cleaner is released, and a steel wire rope with a ring is used to put the ring into the fixed hook at the front end of the cleaner. At this time, after the coke pushing palm is pushed into the carbonization chamber for 0.5 meters, the locking plate is flipped backward using a steel pipe with a hook to release the fixation, and the steel wire rope is pulled to erect the cleaner, and then the coke pushing palm is started to drive the cleaning device above forward according to the normal coke pushing steps, and the condensed coke deposits on the furnace top are started to be cut in the carbonization chamber. The cut coke deposits are directly burned at high temperature in the carbonization chamber. After cleaning is completed, during the retreat of the coke pushing rod, the cleaner can be automatically retracted when it encounters foreign objects, so that the safety lock fixes the cleaner through the position difference with the cleaner.

[0029] The beneficial effects of the present invention are:

[0030] 1. The present invention can not only reduce the unorganized emission of smoke dust during the coal loading operation of the coke oven, but also reduce the probability of carbonization chamber top carbonization chamber collapse caused by carbonization during coal loading, with significant economic benefits;

[0031] 2. The present invention effectively solves the problem of carbon deposits generated on the top of the coke oven carbonization chamber for a long time, and by providing a safety lock, it can effectively avoid the occurrence of accidents with the carbon deposit cleaner. When not in use, the carbon deposit cleaner does not need to be removed, and only needs to be physically locked by the safety lock, which is highly portable.

[0032] 3. The material of the carbon deposit cleaner in the present invention is high manganese steel, which is the same as the material of the coke pushing palm of the coke pushing car, and the thickness is 30mm, which can not only effectively ensure the strength of the carbon deposit cleaner, but also ensure the high temperature resistance of the cleaner.
