Dust cleaning trolley for steelmaking dust removal pipeline

Abstract

The present invention relates to a steelmaking dedusting pipeline dust cleaning trolley, comprising: a vehicle frame, an ash collecting mechanism, a power device including a drive sprocket, and a scraper chain; the ash collecting mechanism and the power device are respectively fixed on the vehicle frame and Connected by the scraper chain, the power device drives the scraper chain through the drive sprocket to drive the dust collection mechanism to clean the dust removal pipeline when the trolley is moving forward. The dust collection mechanism includes the first connecting rod, the second connecting rod, the telescopic rod, the dust collecting board, the guide sprocket driven by the scraper chain and the dust collecting sprocket; the first connecting rod, the second connecting rod, the frame, the second The second and third bearing seats form a four-bar linkage mechanism, so that the scraper chain forms a scraping surface parallel to the ground; the telescopic rod can be adjusted and stretched, so that the dust collection mechanism can be lowered and raised to the required level, which can be adjusted to the required level. Dust cleaning operation on different height dust surfaces and ensure running balance. The trolley reduces the work intensity of the staff and ensures the personal safety and health of the staff.

Description

technical field [0001] The invention relates to a steelmaking dust removal equipment, in particular to a steelmaking production dust removal production line pipeline auxiliary equipment. Background technique [0002] Dust removal in steelmaking is to collect the high-temperature dust generated during steelmaking, concentrate the ash, and discharge the clean air to the atmosphere. The collection process is: high-temperature flue gas in the furnace → moving elbow → double-arm pipe; and flue gas outside the furnace → roof smoke hood → single-arm pipe; and then enter the mechanical air cooler → booster fan → conveying pipe → cloth bag Dust collector; then separate: clean air → main fan → exhaust chimney and dust → scraper machine → bucket elevator → ash storage bin. [0003] The process of dust removal in steelmaking mainly uses air as a carrier to collect dust, and then separates air and dust to realize dust collection. Moving elbows and roof hoods draw dust into the ducts th...

Problems solved by technology

[0004] The dust in the steelmaking electric furnace is connected to the dust collector through pipes. Usually, the flue needs to be cleaned once a quarter; manual cleaning is used. One person uses a shovel to put the dust in a plastic bag, and two people drag the bag to the mouth. After filling, two people drag the plastic bag to the ash discharge port and pour it down. It usually takes more than a dozen people to complete the whole process for a week; the environment inside the pipeline is harsh and dusty, which seriously affects people's health; many people Working in the pipeline, the oxygen consumption in the pipeline is fast, the physical strength is exhausted after working for a long time, and after sweating, the dust sticks to the face, which is very sad.
