Description
Technical Field
The utility model relates to an automatic dredging device of a wet dedusting and sewage draining tank of a converter.
Background
The wet dust removal is adopted in the 120 ton converter for steelmaking, a large amount of flue gas enters the primary wet dust remover, impurities in the flue gas are combined with water, and the water is discharged from the blowdown tank, so that the purpose of purifying the flue gas is achieved. The method is influenced by raw materials in the actual production process, and excessive impurities in the flue gas have heavier mass and are easy to accumulate at the bottom of the pollution discharge tank. In the on-site production process of 120 ton converter in steel mill, dredging the blowdown tank for 1-2 times on average, wherein the dredging blowdown tank area is a coal gas area, the coal gas concentration in the dredging process exceeds 160PPM, the dust in the operation site is more, the physical and mental health of personnel is unfavorable, the risk of coal gas poisoning exists, and the labor intensity of personnel is high. The main problems existing in the dredging operation process of the blow-down tank of the converter tower in the steel mill are as follows: the powder rate of the raw materials used by the converter is high, the sludge in the drain tank of the dust remover is more, the dust remover needs to be dredged regularly, otherwise, the dust remover is blocked, and the converter is shut down. The drain tank is blocked, which can lead to water accumulation of the dust remover, low air quantity, loss of dust removing function and furnace shutdown of the converter. When the turbid circulating water pollution discharge tank of the converter is blocked and dredged, gas leakage is easy to occur, the concentration of on-site gas is high, and gas poisoning is easy to occur when operators operate.
Disclosure of Invention
The utility model aims to provide an automatic dredging device for a converter wet dust removal blowdown tank, which can automatically dredge the blowdown tank by using a mechanical arm, and dredge every furnace smelting is finished, so that environmental protection accidents caused by blockage of the blowdown tank are avoided, manual operation is replaced, the labor intensity of workers is reduced, and the possible gas poisoning risk in the manual blowdown process is also avoided.
The technical scheme adopted by the utility model is that the automatic dredging device of the converter wet dust removal blowdown tank comprises a blowdown tank connected with a dust remover, wherein a blowdown pipe is arranged at one end of the bottom of the blowdown tank, a stainless steel pipe is arranged in the other end of the bottom of the blowdown tank, the outer side end of the stainless steel pipe is connected with a hose through a flange, the hose is connected with a pneumatic cut-off valve, and the pneumatic cut-off valve is respectively communicated with a high-pressure air source and is linked with a converter fan; a piston connecting rod is arranged in the drain pipe, extends to the outer side of the drain pipe through a liquid sealing structure and is connected with an air cylinder.
The utility model is improved as follows, (1) the flange and the stainless steel tube are welded and inserted into the bottom of the sewage tank, the bottom of the sewage tank is stirred by compressed air, and the stainless steel tube is not easy to adhere impurities to cause blockage; (2) A cylinder mounting bracket is welded on a north platform of a drain tank water outlet pipe, a cylinder is mounted on the bracket, a connecting rod is welded on the head of a cylinder piston rod, one end of the connecting rod is inserted into the drain tank water outlet pipe, the connecting rod is driven by the cylinder, and a simulator dredges. The pneumatic cut-off valve is interlocked with the control of the converter fan, after a fan low-speed signal is obtained, the pneumatic cut-off valve is opened, and compressed air stirs impurities at the bottom of the pollution discharge tank for 2 minutes, so that the tank bottom magazine can suspend in water, and is discharged along with water flow in the drainage process, and the situation of blocking a water outlet is reduced; and the pneumatic cut-off valve only performs one switching action when the fan runs at a low speed. When the pneumatic cut-off valve executes three actions, the air cylinder program is started, the electromagnetic valve is powered off three times, the air cylinder reciprocates three times, and the connecting rod is driven to dredge the water outlet pipe of the sewage tank three times, so that the purpose of automatic dredging is achieved.
The improvement effect is as follows: (1) After the automatic dredging device of the blowdown tank is put into use, dredging action is carried out once after smelting of each furnace steel is finished, and environmental protection accidents caused by blockage of the dust remover and the blowdown tank are avoided. (2) After the automatic dredging device replaces manual dredging, labor intensity of workers is reduced, and gas poisoning risks possibly existing in the manual pollution discharge process are avoided.
