Description

Technical Field

[0001] The utility model relates to the technical field of steel cleaning, in particular to a spray cleaning device used for steel rolling. Background Art

[0002] Steel rolling is a metal processing technology that compresses the metal billet through the gap between a pair of rotating rollers, thereby reducing the cross-section of the material and increasing its length. This process is mainly completed through pressure processing and is the most common production method for steel. Cleaning the steel after rolling is very necessary, which is of great significance to improving steel quality, ensuring production safety and extending the service life of steel.

[0003] During the existing steel rolling process, impurities such as oxides, oil stains, and iron filings may adhere to the surface of the steel. These impurities not only affect the appearance of the steel and increase the difficulty of subsequent processing, but oxides and oil stains may also cause the toughness, strength, and corrosion resistance of the steel to decline, thereby affecting the service life and safety of the steel, thereby reducing its surface finish and precision and affecting the overall quality of the steel.

[0004] For example, an automatic cleaning device for a steel conveyor belt disclosed in the announcement number CN214933588U, in which the steel is cleaned by spraying water through a nozzle inside the cleaning box, but the nozzle is arranged on the top of the steel, so only one side of the steel can be cleaned, and all sides of the alloy cannot be cleaned at the same time. It is necessary to manually clean multiple sides repeatedly and turn over, which not only increases labor costs and energy consumption, but also greatly increases cleaning time and workload, and reduces cleaning efficiency.

[0005] Therefore, it is necessary to invent a spray cleaning device for steel rolling to solve the above problems. Utility Model Content

[0008] Preferably, a supporting leg is fixedly installed below the conveyor belt, and there are four supporting legs. The four supporting legs are perpendicular to the conveyor belt, so that the supporting legs can ensure the stable placement of the cleaning device.

[0009] Preferably, dust suction pipes are provided at the upper and lower ends of the conveyor belt, and dust suction hoods are provided on the dust suction pipes, so that the dust suction pipes at the upper and lower ends can perform dust suction treatment on the upper and lower surfaces of the steel at the same time.

[0010] Preferably, a plurality of the dust hoods are provided, and the plurality of dust hoods are distributed in an equidistant array, so that the dust hoods can pre-absorb most of the loose particles, dust and light pollutants on the surface of the steel.

[0011] Preferably, the water inlet end of the high-pressure water pump is connected to the water outlet end of the water storage tank, and the water outlet end of the high-pressure water pump is connected to the water inlet end of the water pipe, so that the high-pressure water pump can guide the pure water inside the water storage tank into the water pipe.

[0012] Preferably, the No. 1 high-pressure nozzle is arranged directly above the conveyor belt, and there are multiple No. 1 high-pressure nozzles, so that the No. 1 high-pressure nozzle can spray and clean the upper surface of the steel.

[0013] Preferably, the No. 2 high-pressure nozzle is arranged on the left and right sides of the conveyor belt, and there are multiple No. 2 high-pressure nozzles. The No. 3 high-pressure nozzle is arranged directly below the conveyor belt, and there are multiple No. 3 high-pressure nozzles, so that the No. 2 high-pressure nozzle and the No. 3 high-pressure nozzle can spray and clean the left and right sides and the bottom surface of the steel.

[0014] Preferably, the lower side of the No. 1 high-pressure nozzle, the No. 2 high-pressure nozzle and the No. 3 high-pressure nozzle is provided with a water collection tank, so that the water collection tank can centrally collect the water containing impurities after spray cleaning, which is convenient for the subsequent treatment of the water containing impurities.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Through the setting of the fan and the dust hood, the combination of the fan and the dust hood can effectively absorb most of the loose particles, dust and light pollutants on the surface of the steel. The steel surface after dust pretreatment is cleaner, which provides a better foundation for subsequent spray cleaning and surface treatment, thereby greatly improving the efficiency and cleanliness of spray cleaning;

[0017] 2. Through the setting of No. 1 high-pressure nozzle, No. 2 high-pressure nozzle and No. 3 high-pressure nozzle, No. 1 high-pressure nozzle, No. 2 high-pressure nozzle and No. 3 high-pressure nozzle, which are set up on the top, bottom, left and right of the steel, it is possible to achieve simultaneous cleaning of multiple surfaces of the steel, ensuring that each surface of the steel can be fully cleaned. Thus, multi-surface cleaning can complete the cleaning of multiple surfaces at one time, reducing the number of cleaning times and the time for changing steel, which avoids the tediousness and time-consuming of cleaning each surface separately and improves the cleaning efficiency.
