Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction nozzle for continuously cleaning and recovering powder falling from a coke oven fire extinguisher, a bucket, etc. around the rail and scattered.

[0002]

2. Description of the Related Art Generally, a coke oven is constructed by alternately arranging a plurality of carbonization chambers and combustion chambers for heating, and successively charging raw material coal through the coal charging port of each carbonization chamber,
In each combustion chamber, the fuel gas supplied through the fuel gas pipe is burned to heat the respective carbonization chambers by the combustion chambers on both sides, whereby the coal is carbonized to produce coke. The coke that has been carbonized in each carbonization chamber is extruded by the extruder and discharged while the red hot coke is extinguished in a wet or dry fire extinguishing facility, and in transportation,
Fallen powder scattered from fire extinguishers and buckets around the track is scattered.

As described above, in the process of extinguishing the red hot coke discharged from the coke oven or in the process of transporting it, it is necessary to clean the fallen powder falling around the rail in some way. Therefore, at present, cleaning around the railroad lines of the fire engine of this coke oven is done manually by using a shovel, a wheelbarrow, etc. Also,
As for a general road cleaning vehicle, as in Japanese Patent Publication No. Sho 64-80606, the road surface is powdered and granular dust is scraped by a rotating brush in front of the lower part of the vehicle and sent to a storage tank by a conveyor belt, and further, a road cleaner is used to sand the road It is known to scrape up ash and other deposits for cleaning.

[0004]

As described above, the method is performed manually by using a scoop, a wheelbarrow, or the like, or it is found in a road cleaning vehicle as disclosed in Japanese Patent Publication No. Sho 64-80606, which is a general road cleaning vehicle. However, the rail running type mechanization technology for cleaning around the rail where the fire engine runs in the coke oven is
Suction of deposits such as moist coke powder is very difficult and has not been put to practical use. In addition, as in Japanese Patent Publication No. Sho 64-80606, the back filter method is used for scraping off the suction gas, and therefore a small-sized lump is mixed during suction to damage the filter cloth or rain. In use at the time, there is a troublesome problem that the filter cloth is clogged, the suction force is reduced and the capacity is deteriorated, and the maintenance of the filter cloth is indispensable. There is a problem that it cannot be applied to recovery.

As one of the improvements, there is an idea to use a suction nozzle as shown in FIG. 8 as a suction device for sucking fallen powder scattered on the road bed.
According to the suction nozzle as shown in (1), when the granular material 9 becomes a small diameter lump, a very large suction force is required. Nevertheless, it is not applicable when used in the case of rainfall, and there is a problem in that in the case of a fine powdery substance, it floats up in the vicinity of the suction nozzle due to its too large suction force.

[0006]

As a result of intensive development by the inventors who should solve the above-mentioned problems, it is possible to clean and recover the powder or granular material, the small-sized lumps, and the wet and dry states. It is to provide a suction nozzle that can.
The gist of the invention is that, in a suction nozzle for continuously cleaning and collecting fallen powder that has fallen and scattered around the coke oven fire extinguishing train rail, a suction device for sucking the fallen powder scattered on the roadbed is provided, and the suction is performed. The apparatus is equipped with a suction nozzle having various shapes according to the state of the powdery or granular material while being attracted to the suctioning tube, and a device for forcibly inducing and sucking the powdery or granular material. The coke oven fire extinguishing train features a line cleaning suction nozzle.
