Description

Technical Field

[0001] This invention relates to the field of automatic cleaning technology for zinc-aluminum-magnesium strips, specifically to an automatic blowing and cleaning device for zinc ash on the surface of zinc-aluminum-magnesium strip steel. Background Technology

[0002] After hot-dip galvanizing, zinc-aluminum-magnesium steel strips will have a large amount of zinc ash and zinc slag impurities attached to their surface. If these are not cleaned in time, they will directly affect the quality of the finished products in subsequent processing steps such as spraying, coating, and stamping, and may cause defects such as coating peeling, surface defects, and reduced corrosion resistance.

[0003] Currently, the industry's conventional cleaning methods are mainly divided into two categories: manual wiping and fixed air knife blowing. Manual cleaning is labor-intensive and inefficient, and cannot be matched with high-speed continuous strip steel production lines. In addition, manual wiping can easily scratch the strip steel surface. Traditional fixed blowing equipment can only blow the fixed area of ​​the strip steel, and cannot be adapted to zinc-aluminum-magnesium strip steel of different widths and specifications. There are blind spots in the cleaning, and zinc ash is easy to remain. At the same time, there is no matching collection structure for the zinc ash dust after blowing and stripping. The dust is scattered and accumulated on the surface of the equipment and strip steel, forming secondary pollution. Frequent shutdowns are required to clean the accumulated dust, which seriously reduces the stability of continuous operation of the production line.

[0004] Existing cleaning equipment lacks an adaptive fitting cleaning structure. When the strip steel has slight warping or thickness tolerance, the cleaning components cannot fit tightly against the plate surface, resulting in incomplete removal of zinc ash. Furthermore, the cleaning and vacuuming mechanisms are set up separately, and the cleaning and vacuuming actions cannot be synchronized, resulting in poor overall practicality and cleaning stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic blowing and cleaning device for zinc ash on the surface of zinc-aluminum-magnesium strip steel, which has the advantages of strong practicality and good stability, and solves the problems mentioned in the background technology.

The moving device 3 is slidably mounted on the equipment frame, and the cleaning device 4 is fixed at the lower end of the mounting bracket 301 of the moving device 3. The filter assembly 5 is detachably installed on the top of the vacuum box 202, and a pull-out collection cabinet 203 is provided at the bottom of the vacuum box 202. In this solution, the dust collection device 2 collects and sweeps dust, and the dust collection box 202 is equipped with a collection cabinet 203 to store ash; the moving device 3 drives the cleaning device 4 to sweep horizontally for full coverage; the cleaning device 4 relies on the sleeve 401, buffer spring 402, telescopic rod 403, and cleaning brush 404 to adaptively adhere to the plate surface to remove dust; the filter assembly 5 completes solid-gas separation through the air pump 501 and filter screen 502. The entire structure works together to achieve automated cleaning and dust collection, solving the problems of blind spots and secondary dust pollution.

[0019] In a preferred embodiment: the winding base 101 of the winding device 1 is an annular support base, an inner rotating disk 102 is provided at the center of the winding base 101, a winding shaft core 104 is assembled at the center of the inner rotating disk 102, and multiple sets of first auxiliary rollers 103 are arranged in an annular array on the winding base 101. The first auxiliary rollers 103 are in contact with the outer side of the winding shaft core 104 for strip steel limiting and guiding. In this design, the annular winding base 101 provides stable load-bearing capacity, while the inner rotating disk 102 and winding shaft core 104 ensure smooth winding of the strip. The first auxiliary rollers 103 arranged in annular positions provide multi-point limiting to prevent the strip from deviating or jumping, ensuring that the strip surface is flat when entering the cleaning station.

[0020] In a preferred embodiment: a second auxiliary roller 302 is provided at the bottom of the mounting frame 301 of the moving device 3, and the second auxiliary roller 302 slides against the frame; the first motor 303 and the second motor 304 are both fixed to the upper end of the mounting frame 301, and the first motor 303 and the second motor 304 cooperate to drive the mounting frame 301 to move back and forth in the direction of the strip width.

[0021] In a preferred embodiment: a buffer spring 402 is installed inside the sleeve 401 of the cleaning device 4. The lower end of the buffer spring 402 is connected to a telescopic rod 403, and the bottom end of the telescopic rod 403 is fixed to a cleaning brush 404. The buffer spring 402 provides a downward elastic pressing force to the cleaning brush 404, so that the cleaning brush 404 fits against the surface of the zinc-aluminum-magnesium strip steel. In this solution, the sleeve 401 limits the buffer spring 402, and the buffer spring 402 pushes the telescopic rod 403 to allow the cleaning brush 404 to adapt to the unevenness and thickness difference of the plate surface, tightly peel off the zinc ash, and avoid missed cleaning and scratching of the strip steel.

[0022] In a preferred embodiment: the corrugated pipe 204 supporting the vacuuming device 2 is a retractable flexible pipe. The corrugated pipe 204 retracts and extends synchronously with the moving device 3, continuously connecting the vacuuming box 202 and the cleaning station of the cleaning brush 404. In this solution, the corrugated pipe 204 extends and retracts synchronously with the moving device 3, continuously connecting the dust collection box 202 with the cleaning station, and maintaining stable negative pressure dust collection throughout the process to prevent dust from floating and re-attaching to the steel strip.

[0023] In a preferred embodiment: the filter assembly 5 is snapped into the top opening of the dust collection box 202, the air pump 501 is located at the center of the filter assembly 5, and the filter screen 502 is arranged around the air pump 501; the air pump 501 generates negative pressure when it runs, and sucks in the zinc ash dust generated during cleaning through the corrugated pipe 204; the filter screen 502 intercepts the solid zinc ash, and the dust settles into the collection cabinet 203. In this solution, the filter assembly 5 is easy to install and remove, the air pump 501 provides negative pressure suction, and the filter screen 502 intercepts zinc ash and causes it to settle into the collection cabinet 203, thereby achieving solid-gas separation and protecting the air pump 501 from dust wear and blockage.

[0024] In a preferred embodiment: the collection cabinet 203 is slidably inserted into the lower part of the dust collection box 202, and a pull handle is provided on the outside of the collection cabinet 203, which can be pulled out separately to clean the accumulated zinc ash inside. In this solution, the collection cabinet 203 can be pulled out separately, allowing for quick dust removal without disassembling the entire machine, shortening downtime, and preventing dust spillage during the pull-out process, thus reducing the labor intensity of manual cleaning.

[0025] Working principle: Zinc-aluminum-magnesium strip steel completes continuous conveying operation through the winding device 1. The winding base 101 provides support for the entire winding structure. The first auxiliary roller 103 arranged in a ring, together with the inner rotating disk 102, limits and guides the strip steel on the winding shaft core 104, ensuring that the strip steel moves smoothly and at a uniform speed, and avoiding the strip steel from running off track or shaking.

[0026] During the movement of the strip, the moving device 3 moves back and forth along the width of the strip, and the second auxiliary roller 302 at the bottom of the mounting frame 301 is in contact with the equipment frame to achieve sliding support; the first motor 303 and the second motor 304 work together to drive the mounting frame 301 to move laterally back and forth, driving the cleaning device 4 to move synchronously with the width of the strip, so as to achieve cleaning of the entire width without dead angles.

[0027] The cleaning device 4 contacts the strip surface to complete the zinc ash scraping: the sleeve 401 is equipped with a buffer spring 402, the buffer spring 402 is connected to the telescopic rod 403, and the end of the telescopic rod 403 is fixed with a cleaning brush 404; the buffer spring 402 continuously provides elastic pressure, so that the cleaning brush 404 always fits tightly against the strip surface, adapting to the slight warping and thickness deviation of the strip, and brushing off and peeling off the zinc ash and zinc slag attached to the strip surface.

[0028] The supporting dust collection device 2 simultaneously collects the zinc ash brushed off under negative pressure: the support frame 201 supports the entire dust collection structure, the corrugated pipe 204 connects the dust collection box 202 to the cleaning station, and the dust collection box 202 is equipped with a filter assembly 5; the blower 501 in the filter assembly 5 generates negative pressure suction, which draws the zinc ash dust swept off by the cleaning brush 404 into the dust collection box 202 through the corrugated pipe 204. The filter screen 502 intercepts solid zinc ash impurities, and the dust is blocked and settles in the collection cabinet 203. The clean airflow passes through the filter screen 502 and is discharged, preventing the zinc ash from being sprinkled again and re-adhered to the steel strip surface.

[0029] The entire set of equipment operates in a coordinated manner: the winding device 1 continuously conveys zinc-aluminum-magnesium strip steel, the moving device 3 drives the cleaning device 4 to sweep the zinc ash on the plate surface laterally, the supporting dust suction device 2 removes the fallen zinc ash in real time under negative pressure, the filter component 5 completes the separation of dust, solid and gas, and the collection cabinet 203 can be periodically pulled out to clean the accumulated dust. The entire process is automated to complete the blowing and cleaning of zinc ash on the surface of the strip steel, continuously ensuring the cleanliness of the strip steel surface.
