Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy scrap recycling and processing technology, and in particular to a metal scrap processing device after aluminum profile processing. Background Technology

[0002] Aluminum alloys are widely used in aerospace, automotive, electronics, and construction industries due to their lightweight, high strength, and corrosion resistance. However, the cutting, grinding, and drilling processes of aluminum profiles generate a lot of scrap and debris. This scrap and debris has high recycling value; its greatest value lies in reducing raw material costs for businesses (recycled aluminum is about 70% the price of primary aluminum).

[0003] Of these scraps and debris, larger pieces can be collected and recycled manually by workers, while smaller pieces are usually scattered on the ground, machine tools, and other places, requiring cleaning up after the workshop has stopped operating. This results in these smaller scraps and debris being mixed with a large amount of dust, oil, paper scraps, and other impurities. Therefore, in recycling these smaller scraps and debris, they must first be separated from dust, paper scraps, and other impurities before proceeding with subsequent recycling processes such as smelting.

[0004] Oily impurities tend to adhere to aluminum alloy shavings, making them difficult to separate. Furthermore, dust and aluminum alloy have similar densities, making effective separation through ordinary rinsing or centrifugation challenging. Performing a separate separation and purification process for each type of impurity would significantly increase the complexity of the recycling process, reducing efficiency and increasing costs.

[0005] In addition, the water used in the process of processing metal scrap contains a lot of impurities such as dust and oil. Direct discharge of such water will not only pollute the environment, but also waste water resources and increase costs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a metal scrap processing device after aluminum profile processing, so as to solve the technical problem of how to effectively and cost-effectively and quickly separate aluminum alloy scraps and debris from impurities such as dust and oil.

[0007] To achieve the above objectives, this utility model provides a metal scrap processing device for aluminum profile processing, including a mesh conveyor belt for conveying aluminum alloy scrap, and the processing device further includes:

[0008] A sprayer is installed above the conveyor belt to wash away aluminum alloy debris from the conveyor belt, and a bottom box is provided at the bottom of the conveyor belt;

[0009] A sedimentation tank connected to a bottom tank, wherein the bottom tank is connected to the sedimentation tank via a water pumping pipe;

[0010] The floating oil tank is connected to the sedimentation tank via an intermediate pipe, and the floating oil tank is also connected to the sprayer via a water pump.

[0011] Furthermore, side baffles are provided on both sides of the conveyor belt, and the side baffles are higher than the conveyor belt by -cm.

[0012] Furthermore, the conveyor belt includes a straight section located at the front and rear sides and an inclined section located in the middle, with the sprayer located above the inclined section of the conveyor belt.

[0013] Furthermore, a bracket is fixedly connected to the bottom of the base box, the upper end face of the base box is open, and the conveyor belt is located at the opening on the upper end face of the base box.

[0014] Furthermore, the outlet end of the pumping pipe is located at the bottom of the sedimentation tank, and the inlet end of the intermediate pipe is located at the top of the sedimentation tank.

[0015] Furthermore, the water pump is connected to the floating oil tank via a return water pipe, and the inlet end of the return water pipe is located at the bottom of the floating oil tank.

[0016] Furthermore, the water pump is connected to the sprayer via a water supply pipe, and the sprayer is equipped with multiple high-pressure nozzles for spraying high-pressure water streams.

[0017] Furthermore, a pressure roller is provided between the straight section and the inclined section of the conveyor belt.

[0018] The beneficial effects of this utility model are as follows: 1. Taking advantage of the fact that most aluminum alloy scraps and debris are larger in volume than dust, oil, and other impurities, a mesh conveyor belt is set up as a filter, and then a sprayer washes the aluminum alloy debris on the conveyor belt. This can wash away dust, oil, and other impurities in one go, thus efficiently separating dust, oil, and other impurities from aluminum alloy scraps and debris.

[0019] 2. Wastewater carrying dust, oil, and other impurities enters the bottom tank via a mesh conveyor belt, and is then pumped to a sedimentation tank for settling. Therefore, heavy objects such as dust in the wastewater settle at the bottom of the sedimentation tank. Since the inlet of the intermediate pipe is located at the top of the sedimentation tank, the content of heavy impurities such as dust in the wastewater entering the oil flotation tank through the intermediate pipe is greatly reduced, thus enabling a simple and effective separation of heavy impurities such as dust from the wastewater.

[0020] 3. After the sewage enters the oil flotation tank, it will also settle. Since light impurities such as oil will float on the surface of the sewage, and the inlet of the return water pipe connected to the oil flotation tank is located at the bottom of the oil flotation tank, the content of light impurities such as oil in the water that re-enters the sprayer through the return water pipe and the water supply pipe will be greatly reduced, thus achieving a simple and effective separation of light impurities such as oil from the sewage.

[0021] 4. After two separation processes—sedimentation tank and oil floatation tank—the water used for rinsing aluminum alloy scraps and debris is significantly purified, allowing for multiple reuses. Finally, the sedimentation tank and oil floatation tank are cleaned periodically, and the water is replaced with fresh water. This greatly saves water costs and reduces water waste.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, small scraps and debris are often mixed with a large amount of dust, oil, paper scraps, and other impurities. Therefore, when recycling these small scraps and debris, they must first be separated from the dust, paper scraps, and other impurities before proceeding with subsequent recycling processes such as smelting. However, oily impurities adhere to the aluminum alloy scraps and are difficult to separate. Furthermore, dust and aluminum alloy have similar densities, making effective separation difficult using ordinary washing or centrifugation methods. Therefore, this embodiment uses a mesh conveyor belt 101 to transport the aluminum alloy scraps and debris while separating the dust, oil, and other impurities mixed in.

[0033] A sprayer 113 is installed above the conveyor belt 101. The sprayer 113 is equipped with multiple high-pressure nozzles 114 for spraying high-pressure water to wash away aluminum alloy debris from the conveyor belt 101. In addition, a bottom box 103 is provided at the bottom of the conveyor belt 101. A bracket 104 is fixedly connected to the bottom of the bottom box 103. The upper end face of the bottom box 103 is open, and the conveyor belt 101 is located at the opening on the upper end face of the bottom box 103.

[0034] Preferably, side baffles 102 are provided on both sides of the conveyor belt 101. The side baffles 102 are 10-20cm higher than the conveyor belt 101, and the sprayer 113 is fixedly connected to the side baffles 102.

[0035] Taking advantage of the fact that most aluminum alloy scraps and debris are larger in volume than dust, oil, and other impurities, a mesh conveyor belt 101 is used as a filter, and a sprayer 113 washes the aluminum alloy debris on the conveyor belt 101. This process can wash away dust, oil, and other impurities in one go, thus efficiently separating dust, oil, and other impurities from aluminum alloy scraps and debris.

[0036] Preferably, the conveyor belt 101 includes a straight section located at the front and rear sides and an inclined section located in the middle, with the sprayer 113 located above the inclined section of the conveyor belt 101. A pressure roller 115 is provided between the straight section and the inclined section of the conveyor belt 101.

[0037] The second aspect of this utility model is as follows: Figure 2 , Figure 4 and Figure 5 As shown, the water used in the original process of processing metal scrap contains a lot of impurities such as dust and oil. Direct discharge of this water would not only pollute the environment but also waste water resources and increase costs. Therefore, this embodiment provides a sedimentation tank 107 connected to the bottom tank 103. The bottom tank 103 is connected to the sedimentation tank 107 via a water pumping pipe 106.

[0038] An oil floating tank 109 is also provided, which is connected to the sedimentation tank 107 via an intermediate pipe 108. The oil floating tank 109 is also connected to the sprayer 113 via a water pump 111.

[0039] The key point is that the outlet of the pumping pipe 106 is located at the bottom of the settling tank 107, and the inlet of the intermediate pipe 108 is located at the top of the settling tank 107. The water pump 111 is connected to the floating oil tank 109 through the return water pipe 110, and the inlet of the return water pipe 110 is located at the bottom of the floating oil tank 109.

[0040] Wastewater carrying impurities such as dust and oil enters the bottom tank 103 via the mesh conveyor belt 101, and is then pumped to the sedimentation tank 107 for settling via the pumping pipe 106. Therefore, heavy objects such as dust in the wastewater settle at the bottom of the sedimentation tank 107. Since the inlet of the intermediate pipe 108 is located at the top of the sedimentation tank 107, the content of heavy impurities such as dust in the wastewater entering the oil floating tank 109 via the intermediate pipe 108 is greatly reduced, thus enabling simple and effective separation of heavy impurities such as dust from the wastewater.

[0041] After the sewage enters the oil floating tank 109, it will be allowed to settle. Since light impurities such as oil will float on the surface of the sewage, and the inlet of the return water pipe 110 connected to the oil floating tank 109 is located at the bottom of the oil floating tank 109, the content of light impurities such as oil in the water that re-enters the sprayer 113 through the return water pipe 110 and the water supply pipe 112 will be greatly reduced, thus achieving a simple and effective separation of light impurities such as oil from the sewage.

[0042] Preferably, the water pump 111 is connected to the sprayer 113 through the water supply pipe 112, and the sprayer 113 is provided with multiple high-pressure nozzles 114 for spraying high-pressure water.

[0043] After two separation processes in the sedimentation tank 107 and the oil floater 109, the water used to rinse aluminum alloy scraps and debris is significantly purified, allowing it to be reused multiple times. Finally, the sedimentation tank 107 and the oil floater 109 are cleaned periodically, and then the water is replaced with clean water. This greatly saves water costs and reduces water waste.

[0044] In summary, this invention utilizes the characteristic that most aluminum alloy scraps and debris are larger in volume than dust, oil, and other impurities. It employs a mesh conveyor belt 101 as a filter, and a sprayer 113 washes the aluminum alloy debris from the conveyor belt 101. This process effectively removes dust, oil, and other impurities in a single pass, thus efficiently separating these contaminants from the aluminum alloy scraps and debris.

[0045] Wastewater carrying impurities such as dust and oil enters the bottom tank 103 via the mesh conveyor belt 101, and is then pumped to the sedimentation tank 107 for settling via the pumping pipe 106. Therefore, heavy objects such as dust in the wastewater settle at the bottom of the sedimentation tank 107. Since the inlet of the intermediate pipe 108 is located at the top of the sedimentation tank 107, the content of heavy impurities such as dust in the wastewater entering the oil floating tank 109 via the intermediate pipe 108 is greatly reduced, thus enabling simple and effective separation of heavy impurities such as dust from the wastewater.

[0046] After the sewage enters the oil floating tank 109, it will also be allowed to settle. Since light impurities such as oil will float on the surface of the sewage, and the inlet of the return water pipe 110 connected to the oil floating tank 109 is located at the bottom of the oil floating tank 109, the content of light impurities such as oil in the water that re-enters the sprayer 113 through the return water pipe 110 and the water supply pipe 112 will be greatly reduced, thus achieving a simple and effective separation of light impurities such as oil from the sewage.

[0047] After two separation processes in the sedimentation tank 107 and the oil floater 109, the water used to rinse aluminum alloy scraps and debris is significantly purified, allowing it to be reused multiple times. Finally, the sedimentation tank 107 and the oil floater 109 are cleaned periodically, and then the water is replaced with clean water. This greatly saves water costs and reduces water waste.
