Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil rolling mills, in particular to an oil fume environmental protection mechanism for aluminum foil rolling mills. Background Art

[0002] The aluminum foil rolling mill is an equipment used for rolling, processing and refining of aluminum foil. It can roll the incoming aluminum sheet and strip coils with a thickness of less than 0.5mm through several passes to make it into aluminum foil with a thickness of more than 2×0.0045mm. The aluminum foil rolling mill needs to use a lot of rolling oil during use. A large amount of heat will be released during the rolling process of aluminum foil. Coupled with the heat generated by the operation of the equipment itself, the rolling oil will evaporate and produce oil smoke. The oil smoke generated during the rolling process of the rolling mill will float out from the outlet of the rolling mill body. Part of the oil smoke will float to the plate roller and the angle roller to form oil droplets. During the rolling process, the oil droplets will stick to the surface of the aluminum foil, causing quality defects in the product. Therefore, it is necessary to set an oil fume extraction device at the outlet of the rolling mill body.

[0003] After searching, the Chinese patent announcement number CN214094629U is disclosed, which discloses an environmentally friendly oil fume treatment equipment. By setting up a heat pipe and a water tank, when absorbing exhaust gas or oil fume, a large amount of hot gas is volatilized, thereby wasting a large amount of heat. When filtering oil fume and exhaust gas, the heat is passed into the water tank through the heat pipe, so that the water tank absorbs the heat, thereby heating the water in the water tank, achieving the effect of repeatedly utilizing heat. By setting up a smoke guide chamber and sound-absorbing cotton, it is achieved that during the smoking process, the oil fume that needs to be filtered is transferred to other positions, and the conduction process ensures that no noise is generated during the smoking filtration. Through the dust absorption plate, it is achieved that the particles mixed in the oil fume are effectively adsorbed during the filtration process, thereby achieving the effect of separating the particles and the gas and preventing pollution to the atmosphere.

[0004] However, when the dust collecting plate or the activated carbon adsorption layer is used for filtering, the oil in the oil fume will be absorbed, so that the oil in the volatilized oil fume cannot be recycled. Utility Model Content

[0027] A cooling mechanism is provided in the recovery box 202, and the cooling mechanism includes two groups of cooling plates 301 bolted between the inner walls of the recovery box 202. The two groups of cooling plates 301 are staggered in an eight-shaped manner to increase the travel of oil smoke in the recovery box 202 and improve the recovery effect. A wavy water groove is provided in the cooling plate 301, and two side walls of the recovery box 202 are provided with two water passage cavities arranged up and down, and the two ends of the water groove are respectively connected to the two water passage cavities on the same side.

[0028] The cooling mechanism also includes a water supply component, which includes a water tank 302 with a refrigeration function placed on the ground at the rear side of the box body 1. Water pumps 303 are bolted to both sides of the water tank 302. The water outlet of the water pump 303 is connected to a water inlet pipe 304. The other end of the water inlet pipe 304 is connected to one of the water passage cavities on the same side. A water outlet pipe 305 is connected between the recovery box 202 and the water tank 302. One end of the water outlet pipe 305 is connected to another water passage cavity on the same side, and the other end is connected to the inside of the water tank 302.

[0029] A cleaning mechanism is provided in the recycling box 202, and the cleaning mechanism is used to scrape off the oil condensed on the surface of the cooling plate 301 in time. The cleaning mechanism includes a scraper 407 slidably connected to the outer wall of the cooling plate 301, and a connecting plate 406 is bolted between two adjacent scrapers 407. A sliding rod 405 is inserted at the top of the connecting plate 406. The top of the sliding rod 405 extends out of the recycling box 202 and is bolted to a lifting plate 403. The sliding rod 405 is slidably connected to the recycling box 202, and the lifting plate 403 drives the sliding rod 405 to drive the connecting plate 406 and the scraper 407 to move up and down.

[0030] The cleaning mechanism also includes a power component, which is used to drive the lifting plate 403 to rise and fall.

[0031] Working principle: When in use, start the exhaust fan 203, and draw the oil smoke in the box body 1 into the recovery box 202 through the wind collecting hood 204 and the air inlet pipe 205. The high-temperature oil smoke gradually condenses into liquid oil droplets after encountering the colder cooling plate 301. Some of the liquid oil droplets flow downward along the cooling plate 301, and some of the oil droplets adhere to the cooling plate 301. Start the rotating motor 401, and the rotating motor 401 drives the screw rod 402 to rotate. The screw rod 402 drives the lifting plate 403 to move downward. The lifting plate 403 drives the sliding rod 405 to drive the connecting plate 406 and the scraper 407 to move downward. The scraper 407 is used to scrape off the condensed oil on the cooling plate 301 in time. To ensure the cooling effect of the cooling plate 301, the condensed oil droplets gradually flow into the collection box 5, which is convenient for recovering the condensed oil and improving resource utilization. The water pump 303 is started to transport the cold water in the water tank 302 to one of the water passage chambers through the water inlet pipe 304, and then the water is diverted to different cooling plates 301 by the water passage chamber. After the cold water flows through the cooling plate 301 for one circle, it returns to the water tank 302 through the water outlet pipe 305. The cold water circulates continuously in the cooling plate 301, thereby ensuring that the cooling plate 301 is always at a lower temperature. The two groups of cooling plates 301 are staggered in an eight-shaped arrangement to increase the travel of the flue gas in the recovery box 202 and improve the recovery effect.
