Description

Converter group cover water seal cylinder with backwashing mechanism

technical field

The utility model relates to the field of converter sealing, in particular to a converter group cover water seal cylinder.

Background technique

The converter will produce a lot of smoke and gas during the smelting process. In order to prevent these smoke and dust, especially the gas from overflowing or the outside air from entering the fume hood, the converter uses a water seal between the fixed fume hood and the skirt cover. The water seal is sealed, and the water seal water flows into the water seal cylinder after cooling the water seal insert plate. After forming a certain water level in the water seal cylinder, it is discharged through the overflow port. During the production and smelting process, due to the smoke and dust will inevitably enter the water In the sealing cylinder, the silt deposit formed by the combination of smoke dust and water sealing water gradually accumulates in the water sealing cylinder. Due to the large proportion of the settled silt, it cannot be taken out by the water sealing water from the overflow port, so that the sludge in the cylinder is serious. Because the sludge in the cylinder If the accumulation is too high, the water seal cylinder is held up by the inserting plate when the skirt is lifted up and down, and the skirt cannot be effectively controlled to adjust the differential pressure at the furnace mouth. Also, because the skirt does not rise in place, the furnace mouth is very easy when the converter is tilted. Colliding with the cooling water pipe of the skirt cover caused water leakage and the furnace was forced to shut down. The water-sealed cylinder could not be effectively cooled to the extent that the cylinder was burned and leaked due to mud buildup, which not only affected production, but also had a short service life. The furnace had to be shut down every time the furnace was in operation Carrying out mud cleaning or welding repairs has seriously affected the normal production of steelmaking.

Contents of the invention

The technical problem to be solved by the utility model is to provide a converter group cover water seal cylinder with a backwashing mechanism, through the flushing nozzle to drive the precipitated smoke and dust to be discharged through the flushing sewage outlet with the flowing water, so as to prevent the accumulation of sludge in the cylinder and reduce the water seal cylinder Body burning, leakage, and skirt cover lifting distance are not in place, resulting in leakage of skirt cover cooling water pipes and forced shutdown of the furnace, improving the service life of spare parts.

The utility model is realized in the following way: a converter group cover water seal cylinder with a backwashing mechanism, including a water seal cylinder body and a water seal insert plate, the water seal cylinder body and the water seal insert plate form an insert plate water seal mechanism, and the water seal cylinder There is an overflow drain on the upper side wall of the body, and a flushing sewage outlet is also opened on the bottom side wall of the water-sealed cylinder. The bottom of the water-sealed cylinder is equipped with a flushing nozzle mechanism, and the flushing nozzle mechanism is connected with the external flushing pipe The road is connected.

The flushing nozzle mechanism includes a plurality of flushing nozzles, the plurality of flushing nozzles are arranged in an annular array at the bottom of the water-sealed cylinder, and the plurality of flushing nozzles communicate with the main water inlet pipeline.

The flushing nozzle is detachably installed on the bottom of the water-seal cylinder through a screw thread and a bulkhead.

There are totally 24 flushing nozzles.

The converter group cover water seal cylinder with a backwashing mechanism of the utility model uses the surplus dust collecting water to make the water in the cylinder flow rapidly through the flushing nozzle, and the precipitated smoke and dust are discharged through the flushing sewage outlet along with the flowing water, thereby preventing the sludge from being in the cylinder Stacking to ensure the normal movement of the up and down lifting distance of the lifting skirt and the effective cooling of the water-sealed cylinder, reducing the burning of the water-sealed cylinder, leakage, and faults caused by the leakage of the cooling water pipe of the skirt and the forced shutdown of the skirt caused by the insufficient lifting distance of the skirt, and improving spare parts Long service life, reduce maintenance cost, improve efficiency, so as to ensure the stable production of steelmaking.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Example 1

As shown in Figures 1 and 2, a converter group cover water seal cylinder with a backwashing mechanism includes a water seal cylinder 1 and a water seal insert 2, the water seal cylinder 1 and the water seal insert 2 form an insert water seal mechanism, The upper side wall of the water-sealed cylinder 1 is provided with an overflow drain 3, and the bottom side wall of the water-sealed cylinder 1 is also provided with a flushing and sewage outlet 5, and the bottom of the water-sealed cylinder 1 is equipped with a flushing nozzle mechanism 4 , the flushing nozzle mechanism 4 is connected with the external flushing pipeline.

In the utility model, the external flushing pipeline can use the surplus dust-collecting water to directly flush into the water-sealed cylinder 1 through the flushing nozzle 41, so that the water in the cylinder can flow quickly, so that the smoke and dust deposited in the water-sealed cylinder 1 during smelting Then the fast flowing water is discharged through the flushing sewage outlet 5, so as to prevent the accumulation of sludge in the cylinder, ensure the normal movement of the lifting skirt 6 up and down and the effective cooling of the water seal cylinder 1, and eliminate the collision of the cooling water pipe of the lifting skirt 6 The resulting water leakage and the water-sealed cylinder cannot be effectively cooled due to mud build-up, causing the cylinder to burn and leak.
