Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, and in particular to a chip collector for fine aluminum profile processing. Background Technology

[0002] During the finishing process of aluminum products, sputtering debris is generated and needs to be collected. The cutting process produces a large amount of debris, including large chunks and small powders. In particular, the powder spreads in the air, which is very harmful to human health. The powder can enter the respiratory tract or adhere to the skin pores. After entering the body, it will remain in the lungs and respiratory tract. Long-term exposure can also cause aluminum poisoning.

[0003] Existing technologies primarily focus on collecting large, visible aluminum powder particles. One method utilizes the particle's own gravity for collection, such as the chip collection device for aluminum plate processing disclosed in patent document CN218284764U. This involves placing the aluminum plate on a grid plate 4 for processing, with the processing chips and rinsing water falling through the grid plate 4. A movable plate 22 reciprocates to achieve real-time cleaning, followed by a series of complex transmission processes. This method is clearly cumbersome and has limited effectiveness in practical applications, failing to thoroughly remove aluminum dust particles from the air. Another method, as shown in patent document CN216657272U, involves a directional sputtering chip collection device for precision aluminum product processing. This method uses a filter screen on the outer side of the arc surface above the collection cylinder, followed by suction using a fan to collect the chips. However, this method only collects larger particles. A large amount of aluminum powder is generated during the cutting process, and the remaining aluminum powder cannot be collected. After exhaust, this pollutes the environment, and these fine particles can still disperse in the working environment.

[0004] In summary, both of the above methods of collecting debris lack the ability to collect extremely small aluminum powder particles that are scattered in the air. Therefore, the exhaust gas still needs to be treated by a special dust treatment device, which is complicated, costly, and unsuitable for small processing workshops with low automation.

[0005] A scrap collector for fine aluminum profile processing is provided. By modifying the pipe shape and controlling the water level, it can repeatedly collect fine aluminum powder particles from the air, ensuring the aluminum powder collection effect. Summary of the Invention

[0006] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides an aluminum profile fine processing debris recycling collector, which effectively solves the problems of insufficient dust collection capacity, high cost, cumbersome process and unsuitability for small processing workshops in the prior art.

[0007] The technical solution includes a ventilation duct and an arc-shaped pipe below it. The ventilation duct has an air inlet and an air outlet. The air inlet is located to the left of the air outlet. The air inlet and the air outlet are connected by a spiral bend. The spiral bend is composed of multiple bends connected end to end, and the lower ends of the multiple bends are at the same height. Air enters the bend through the air inlet, and then enters the next bend by going down and then up, and finally exits from the air outlet. The arc-shaped tube is open upwards. The lower end of each bend is connected to the arc-shaped tube via a vertical connecting pipe. The height of both ends of the arc-shaped tube is higher than the height of the lower end of the bend. The arc-shaped tube cavity is filled with water, the water level is higher than the connecting pipe and enters the spiral bend cavity of the ventilation duct, but the water does not block the spiral bend. The arc-shaped tube contains a sliding component that can slide along the arc-shaped tube. Both ends of the sliding component are fixed with arc-shaped rods, which can drive the sliding component to slide left and right to achieve slag discharge.

[0008] Furthermore, the spiral bend has a variable diameter spiral structure.

[0009] Furthermore, the cross-sectional area of ​​the spiral bend gradually increases.

[0010] Furthermore, the sliding element is made of a filter screen.

[0011] Furthermore, the arc-shaped tube is provided with slag discharge cylinders at both ends, with the end of the slag discharge cylinder away from the arc-shaped tube inclined downwards.

[0012] Furthermore, the sliding member is a hollow shell made of filter screen, with the hollow shell fitting against the side wall of the arc-shaped plate around its perimeter, and the upper ends of the left and right side plates of the sliding member tilting to the sides.

[0013] This invention features an ingenious structure. The curved design of the ventilation duct ensures that air containing aluminum shavings can pass over the water surface multiple times, achieving multiple cleaning processes. The height of the highest points in the multiple bends of the ventilation duct gradually increases, making it increasingly difficult for aluminum powder to pass through, further enhancing the aluminum powder collection capacity. The gradually increasing cross-section of the ventilation duct also reduces the air velocity and increases the contact area between the air and the water surface, maximizing the collection of aluminum powder. The entire collection process requires no power drive, occupies a small area, has excellent collection effect, is easy to process, and is very suitable for use in small workshops.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 4 The present invention includes a ventilation duct 1 and an arc-shaped pipe 2 below it. The ventilation duct 1 has an air inlet 3 and an air outlet 4. The air inlet 3 is located to the left of the air outlet 4. The air inlet 3 and the air outlet 4 are connected by a spiral bend. The spiral bend is composed of multiple bends connected end to end, and the lower ends of the multiple bends are at the same height. Air enters the bend through the air inlet 3, and then enters the next bend by going down and then up along the bend, and finally exits from the air outlet 4. The arc-shaped pipe 2 is an arc shape with the opening facing upward. The lower end of each bent section is connected to the arc-shaped pipe 2 via a vertical connecting pipe 5. The height of both ends of the arc-shaped pipe 2 is higher than the height of the lower end of the bent section. The arc-shaped pipe 2 is filled with water, the water level is higher than the connecting pipe 5 and enters the spiral bend cavity of the ventilation duct 1, but the water does not block the spiral bend. The arc-shaped tube 2 contains a sliding member 6 that can slide along the arc-shaped tube 2. Both ends of the sliding member 6 are fixed with arc-shaped rods 7, which can drive the sliding member 6 to slide left and right to achieve slag discharge.

[0020] In order to significantly increase the difficulty of aluminum powder passing through and enhance the dust removal effect, the spiral bend has a variable diameter spiral structure.

[0021] In order to gradually reduce the airflow velocity, decrease the forward momentum of the aluminum powder particles, and increase the contact area between the aluminum powder and the water surface, the cross-sectional area of ​​the spiral bend is gradually increased.

[0022] To facilitate slag discharge, the sliding component 6 is made of a filter screen.

[0023] In order to facilitate the removal of aluminum powder and aluminum chips that have settled in the arc-shaped tube 2, slag discharge cylinders 8 are provided at both ends of the arc-shaped tube 2, with the end of the slag discharge cylinder 8 away from the arc-shaped tube 2 tilted downward.

[0024] In order to facilitate the smooth entry of debris into the slag discharge cylinder 8, the sliding member 6 is a hollow shell made of filter screen. The hollow shell is fitted with the side wall of the arc plate around its perimeter, and the upper ends of the left and right side plates of the sliding member 6 are inclined to the sides.

[0025] Of course, in order to facilitate water replacement and drainage, a valve can be installed at the bottom of the arc-shaped pipe 2 to control the water replacement and slag discharge inside the arc-shaped pipe 2.

[0026] It should be noted that, in order to increase the base area of ​​the air and water surface, the cross-section of the ventilation duct 1 can also be improved, for example, by setting it to an elliptical cross-section.

[0027] During use, the blower blows air towards the cutting area, and blows the air containing aluminum powder and debris generated from cutting the aluminum profile into ventilation duct 1. At this time, the air has a certain initial velocity. When passing through the next spiral bend, the direction of the air is forced to change. The larger debris and larger aluminum powder particles move along the outer edge of the inner wall of the spiral bend until they reach the water surface and are trapped in the water. The air continues to move forward and enters the next spiral bend, repeating the above cleaning process. After repeating the above process many times, the dust and debris in the air can be completely absorbed.

[0028] The debris and dust particles that sink into the water fall into the arc-shaped tube 2 through the connecting pipe 5 and settle at the bottom. When enough aluminum chips and powder accumulate at the bottom, the arc-shaped rod 7 is pushed or pulled to make the sliding member 6 slide along the arc-shaped tube 2. The sliding member 6 moves the deposited aluminum powder and aluminum chips closer to the slag discharge cylinder 8. When the sliding member 6 reaches the slag discharge cylinder 8, the left and right side plates of the sliding member 6 are inclined, so the aluminum powder and aluminum chips can enter the slag discharge cylinder 8. A container is placed below the slag discharge cylinder 8 to collect aluminum powder and aluminum chips.

[0029] In the above process, as the air to be filtered passes through multiple spiral bends, the radii of these bends gradually increase. For a single spiral bend, with the water-covered section as the dividing line, during the downward phase, the aluminum powder particles and debris within the air move downwards, their combined weight resulting in a faster speed and greater centrifugal force, maximizing contact with the water. After passing the water surface, the air begins to move upwards, which is the climbing phase. Due to the weight of the debris and aluminum powder particles themselves, as well as the friction between them and the side walls of the spiral bend, the passage of debris and aluminum powder particles becomes more difficult. This process is repeated multiple times until the aluminum dust and particles in the air are completely filtered out.

[0030] The above process is sufficient to separate aluminum powder and aluminum shavings from the air. However, in order to further enhance the filtration effect, the flow area of ​​ventilation duct 1 is gradually increased, which also gradually reduces the air velocity. This further allows the dust particles to remain in ventilation duct 1.

[0031] Of course, the ventilation duct 1 in this invention is a spiral structure with a variable diameter. In fact, based on the above process and working principle, it is not difficult to conclude that the ventilation duct 1 can also be made into a spiral structure with a constant diameter, which can also achieve the purpose of collecting aluminum powder.

[0032] Compared to traditional aluminum powder and shavings collection equipment, this invention does not require an additional power source. It can collect aluminum powder and shavings by utilizing its own structure and characteristics. Its unique structure and the more spiral bends within a limited space, the better the collection effect, making it suitable for use in small and medium-sized processing workshops.

[0033] This invention features an ingenious structure. The curved design of the ventilation duct 1 ensures that air containing aluminum shavings can pass over the water surface multiple times, achieving multiple cleaning processes. The height of the highest points in the multiple bends of the ventilation duct 1 increases sequentially, making it increasingly difficult for aluminum powder to pass through, further enhancing the aluminum powder collection capacity. The gradually increasing cross-section of the ventilation duct 1 also reduces the air velocity and increases the contact area between the air and the water surface, maximizing the collection of aluminum powder. The entire collection process requires no power drive, occupies a small area, has excellent collection effect, is easy to process, and is very suitable for use in small workshops.
