Description

Technical Field

[0001] This utility model belongs to the field of aluminum plate casting and rolling technology, and specifically relates to an aluminum casting and rolling surface cleaning and cooling device. Background Technology

[0002] During the aluminum casting and rolling process, the surface of the cast and rolled aluminum strip is prone to adhering to impurities such as oxide scale and aluminum chips. At the same time, the aluminum strip temperature is relatively high (about 400-550℃), and timely cooling treatment is required to ensure the quality of subsequent processing.

[0003] In existing technologies, cleaning and cooling are usually performed separately. Cleaning often uses wire brushes or simple scrapers, which easily generates a large amount of high-temperature aluminum shavings. These shavings fly everywhere, polluting the environment and potentially falling into the roll gaps or sheet surface, causing secondary defects or equipment damage. Cooling, on the other hand, often uses simple water spraying or air cooling, which results in poor cooling uniformity and can easily lead to excessive transverse temperature differences in the aluminum strip, causing poor sheet shape (such as edge waviness, center waviness, etc.) and affecting the quality of the final product.

[0004] Therefore, there is an urgent need for a surface cleaning and cooling device for aluminum casting and rolling to solve the above problems. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides an aluminum casting and rolling surface cleaning and cooling device, comprising a conveying roller group, a pretreatment mechanism, a main treatment mechanism, a cooling mechanism, and a drying mechanism. The conveying roller group includes multiple conveying rollers arranged at intervals, on which aluminum casting and rolling plates are conveyed. The pretreatment mechanism, main treatment mechanism, cooling mechanism, and drying mechanism are arranged sequentially along the conveying direction of the aluminum casting and rolling plates. The pretreatment mechanism and the main treatment mechanism are both located on the right side of the aluminum casting and rolling plates. The pretreatment mechanism includes a fixed frame, two elastic scrapers mounted on the fixed frame, a first air pump, and several first high-pressure nozzles. The two elastic scrapers are respectively located on the upper and lower sides of the aluminum casting and rolling plates, and the scraping blades of the two elastic scrapers are in close contact with the upper and lower surfaces of the aluminum casting and rolling plates, respectively. The first air pump is located above the fixed frame, and the several first high-pressure nozzles are all located on the fixed frame and connected to the first air pump through a first air guide pipe.

[0006] The main processing mechanism includes a frame, two cleaning rollers rotatably connected to the frame, a drive motor for driving the two cleaning rollers to rotate, a second air pump, and several second high-pressure nozzles. The two cleaning rollers are respectively located on the upper and lower sides of the aluminum cast and rolled plate. Both cleaning rollers are covered with wear-resistant brushes. The wear-resistant brushes of the two cleaning rollers abut against the upper and lower surfaces of the aluminum cast and rolled plate, respectively. The rotation direction of the cleaning rollers is opposite to the conveying direction of the aluminum cast and rolled plate, so that the wear-resistant brushes and the surface of the aluminum cast and rolled plate form reverse friction, which improves the impurity removal effect. The drive motor is fixedly mounted on the frame, the second air pump is located above the frame, and several second high-pressure nozzles are all mounted on the frame and connected to the second air pump through second air guide pipes.

[0007] Both the cooling mechanism and the drying mechanism are located above the aluminum cast and rolled plate. The cooling mechanism is used to cool the aluminum cast and rolled plate, and the drying mechanism is used to dry the aluminum cast and rolled plate. Optionally, the fixing frame includes a vertical plate and two horizontal plates fixedly connected to the vertical plate. The two horizontal plates are located on the upper and lower sides of the aluminum cast and rolled plate, respectively, and two elastic scrapers are fixed on the two horizontal plates. The fixing frame is provided with support legs at the bottom.

[0008] Optionally, the elastic scraper is made of polyurethane and is set at an angle to ensure that the scraper can effectively remove large impurities from the surface of the aluminum cast-rolled plate, while avoiding damage to the surface of the aluminum cast-rolled plate.

[0009] Optionally, several first high-pressure nozzles are all inclined and directed toward the contact point between the elastic scraper and the aluminum cast-rolled plate, which can blow away large pieces of impurities scraped off by the elastic scraper from the surface of the aluminum cast-rolled plate, while avoiding impact deformation of the aluminum cast-rolled plate by the high-pressure airflow.

[0010] Optionally, the wear-resistant brush is made of nylon filaments, and its length can be changed according to the impurities on the surface of the aluminum cast plate.

[0011] Optionally, several second high-pressure nozzles are inclined and directed toward the contact point between the cleaning roller and the aluminum cast plate, which can blow away the fine impurities brushed off by the cleaning roller from the surface of the aluminum cast plate, while avoiding the impact deformation of the aluminum cast plate caused by the high-pressure airflow.

[0012] Optionally, the cooling mechanism includes a cooling water tank, a water supply pipe, and several spray heads. The top of the cooling water tank is equipped with a water inlet, and the bottom of the cooling water tank is equipped with a thermometer. The thermometer is a Modline5 infrared thermometer used to detect the surface temperature of the aluminum cast and rolled plate. The water supply pipe is connected to the cooling water tank and is equipped with a water pump and a first valve. Several spray heads are evenly arranged at the bottom of the water supply pipe, and the outlets of the spray heads all face the upper surface of the aluminum cast and rolled plate to ensure uniform cooling of all areas of the aluminum cast and rolled plate surface.

The air duct is connected to the air outlet of the hot air blower, a second valve is installed on the air duct, and several air guide hoods are evenly arranged at the bottom of the air duct.

[0014] Optionally, the air guide shroud is trumpet-shaped, and the air outlet of the air guide shroud faces the upper surface of the aluminum cast and rolled plate. The distance between the air guide shroud and the surface of the aluminum cast and rolled plate is 5-10cm, which can quickly dry the moisture on the surface of the aluminum cast and rolled plate and prevent the aluminum cast and rolled plate from deforming due to local overheating.

[0015] Optionally, two slag collection troughs are provided on the left side of the aluminum cast and rolled plate, and the two slag collection troughs correspond one-to-one with the pretreatment mechanism and the main treatment mechanism, respectively. The slag collection troughs are generally U-shaped, with baffles on the top and sides, and a receiving cavity at the bottom. A drawer is provided in the receiving cavity. The slag collection troughs are used to collect impurities blown down by the first high-pressure nozzle or the second high-pressure nozzle and collect them in the drawer. After processing, the drawer can be removed and the accumulated impurities inside can be cleaned out.

[0016] This utility model also includes other components that enable the aluminum casting and rolling surface cleaning and cooling device to function properly, all of which are conventional technologies in the field. Furthermore, any devices or components not specified in this utility model employ conventional technologies in the field, such as drive motors, water pumps, hot air blowers, first air pumps, and second air pumps.

[0017] The working principle of this invention is as follows: An aluminum cast-rolled plate is conveyed into the device via a set of conveyor rollers. First, it passes through a pretreatment mechanism where an elastic scraper removes large pieces of oxide scale and aluminum shavings from the surface of the plate. Impurities are then blown away by a first high-pressure nozzle and fall into a corresponding slag collection trough. Next, the plate enters the main cleaning mechanism, where a drive motor rotates the cleaning rollers in the opposite direction. A wear-resistant brush removes fine impurities from the surface of the plate, while a second high-pressure nozzle blows them away to prevent residue. Then, the plate enters the cooling mechanism, where cooling water is evenly sprayed onto the surface for cooling. A water collection trough can be installed below the plate to collect wastewater after heat exchange for recycling. Finally, the plate enters the drying mechanism, where hot air generated by a hot air blown onto the surface of the plate through a guide hood for rapid drying. The treated plate is then discharged via the conveyor rollers.

It has a compact structure, reduces the space occupied by the equipment, avoids the aluminum cast and rolled plate from being contaminated with impurities again during the transfer process, and improves production efficiency. (2) The large impurities on the surface of the aluminum cast and rolled plate are first scraped off by the elastic scraper of the pretreatment mechanism, and then the main cleaning mechanism performs double cleaning by the reverse rotating cleaning roller and high pressure nozzle. The impurities are thoroughly removed, effectively improving the surface cleanliness of the aluminum cast and rolled plate. (3) The uniform distribution of the spray nozzles of the cooling mechanism ensures uniform cooling of the aluminum cast plate surface and avoids deformation of the aluminum strip due to uneven cooling. (4) The air drying mechanism quickly dries the cooled aluminum strip to avoid moisture residue affecting subsequent processing, which is highly practical. Attached Figure Description

Subsequently, the aluminum cast-rolled plate 6 enters the main cleaning mechanism, where the drive motor 14 drives the cleaning roller 13 to rotate in the opposite direction. A wear-resistant brush removes fine impurities from the surface of the aluminum cast-rolled plate 6, while simultaneously being blown away by the second high-pressure nozzle 16. To avoid impurities remaining, the aluminum cast plate 6 then enters the cooling mechanism 4.
