Description

Technical Field

[0001] This utility model relates to waste metal recycling equipment, and more specifically, to a metal waste separation device. Background Technology

[0002] Waste typically includes both metallic and non-metallic waste. Waste recycling involves multiple steps. After recycling, the waste undergoes preliminary processing to remove impurities such as mud and stones. Then, the waste is collected and crushed and flattened. After the above processing, the metallic and non-metallic waste usually have a relatively uniform thickness. Among them, metallic waste has a higher recycling value. Therefore, in order to recycle metallic waste, existing technologies have developed metallic waste separation devices to separate metallic and non-metallic waste. Common metallic waste separation devices include air separators, eddy current separators, and strong magnetic separators. Eddy current separators are mainly used to separate non-magnetic metallic waste, such as copper, aluminum, lead, and zinc.

[0003] The eddy current separator includes a housing, a conveying assembly, and a collection bin. The collection bin is specifically used to collect metal waste. A sorting magnetic roller is located at one end of the conveying assembly near the collection bin. The sorting magnetic roller includes a permanent magnet drum and a control circuit. When the eddy current separator is working, the conveying assembly drives the permanent magnet drum to rotate. The control circuit energizes the permanent magnet drum and generates a high-frequency alternating magnetic field on it. When non-magnetic metal passes through the high-frequency alternating magnetic field, eddy currents are induced inside it. These eddy currents generate a magnetic field opposite to the original magnetic field, causing the metal waste to be subjected to the repulsive force of the magnetic field and fly forward along its conveying direction, ultimately achieving separation from the non-metallic waste.

[0004] However, when the waste is dumped onto the conveying assembly, some non-metallic waste will cover the metallic waste. When the area of ​​the covered metallic waste is larger than that of the non-metallic waste covering it, the metallic waste will carry the non-metallic waste along with it when it leaps under the action of magnetic force, causing some non-metallic waste to be mixed into the collection bin, which requires further processing.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a metal waste separation device.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a metal waste separation device, including a housing, a conveying assembly and a sorting magnetic roller, wherein the housing is provided with a feed inlet, the sorting magnetic roller is disposed at the end of the conveying assembly away from the feed inlet, an inclined plate is installed inside the housing below the feed inlet, a screen roller is disposed inside the housing above the inclined plate, and a gap is formed between the surface of the inclined plate and the outer peripheral wall of the screen roller that is greater than the thickness of a single piece of waste but less than the sum of the thicknesses of two pieces of waste, and the conveying assembly is disposed below the inclined plate.

[0008] The present invention is further configured such that: a motor is provided outside the housing and fixed to one end of the screen roller, and the direction of the torque provided by the motor to the screen roller is opposite to the rotation direction of the conveying component.

[0009] The present invention is further configured such that: a scraper is provided inside the casing above the inclined plate, and the distance between the scraper and the outer peripheral wall of the screen roller is less than the thickness of a single piece of waste material.

[0010] The present invention is further configured such that the distance between the end of the scraper near the screen roller and the inclined plate is smaller than the distance between the other end of the scraper and the inclined plate.

[0011] The present invention is further configured such that the conveying speed of the conveying component is greater than the moving speed of the waste on the inclined plate.

[0012] The present invention is further configured such that: both sides of the inclined plate are provided with bent portions fixed inside the machine housing, and the bent portions are provided with guide plates inclined toward the center of the screen roller.

[0013] The present invention is further configured such that the inclined plate is made of high manganese steel.

[0014] In summary, this utility model has the following beneficial effects: When using this metal waste separation device, waste is poured in from the feed inlet and falls onto the inclined plate. Under the action of gravity, the waste moves along the surface of the inclined plate. Some overlapping waste slides along the surface of the inclined plate and collides with the outer peripheral wall of the screen roller. Since the gap only allows single pieces of waste to pass through, this allows overlapping waste to be separated well. The non-overlapping waste enters the conveying assembly along the inclined plate. The conveying assembly transports the waste to the sorting magnetic roller, which generates a repulsive force on the metal waste in the waste and causes it to leap into the collection bin. The overlapping waste is separated by the screen roller, which greatly reduces the possibility of non-metallic waste overlapping on the metal waste. Thus, when the sorting magnetic roller repels the metal waste, the metal waste will not bring the non-metallic waste into the collection bin. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A metal waste separation device, such as Figure 1 As shown, the device includes a housing 1, a conveying assembly 2, and a sorting magnetic roller 3. The housing 1 has a feed inlet 4. The sorting magnetic roller 3 is located at the end of the conveying assembly 2 furthest from the feed inlet 4. Specifically, the sorting magnetic roller 3 is a Senhongyu 1500 type eddy current eccentric magnetic roller. An inclined plate 5 is installed inside the housing 1 below the feed inlet 4. A screen roller 6 is rotatably connected inside the housing 1 above the inclined plate 5. A gap larger than the thickness of a single piece of waste material but less than the sum of the thicknesses of two pieces of waste material is formed between the surface of the inclined plate 5 and the outer peripheral wall of the screen roller 6. The conveying assembly 2 is located below the inclined plate 5, and a collection bin for collecting metal waste is located below the conveying assembly 2. When using this metal waste separation device, waste material is poured in through the feed inlet 4 and falls onto the inclined plate 5. The waste material moves along the surface of the inclined plate 5 under the action of gravity. Some overlapping waste materials slide along the surface of the inclined plate 5 and collide with the outer peripheral wall of the screen roller 6. Since the gap only allows single pieces of waste material to pass through, the overlapping waste materials can be separated well. The non-overlapping waste materials enter the conveying assembly 2 along the inclined plate 5. The conveying assembly 2 conveys the waste material to the sorting magnetic roller 3. The sorting magnetic roller 3 generates a repulsive force on the metal waste in the waste material and makes it leap into the collection bin. The overlapping waste material is separated by the screen roller 6, which greatly reduces the possibility of non-metallic waste material overlapping on metal waste material. Therefore, when the sorting magnetic roller 3 repels the metal waste material, the metal waste material will not bring the non-metallic waste material into the collection bin.

[0020] like Figure 1 and Figure 2As shown, a motor is bolted to the outside of the housing 1. One end of the screen roller 6 is fixedly connected to the motor. During use, the motor provides torque to the screen roller 6, and the direction of this torque is opposite to the rotation direction of the conveying assembly 2. This arrangement ensures that the rotation direction of the screen roller 6 is also opposite to the movement direction of the waste material on the inclined plate 5. When the overlapping waste material comes into contact with the screen roller 6, the waste material on top moves in the opposite direction to the waste material below under the force of the screen roller 6, making it less likely for the overlapping waste material to get stuck in the gaps. The originally overlapping waste material is separated by the screen roller 6, and the separated waste material can continue to slide along the inclined plate 5 towards the conveying assembly 2 under the action of gravity. The inner casing 1 is fixed A scraper 7 is positioned above the inclined plate 5. One end of the scraper 7 is located close to the screen roller 6, and the distance between the scraper 7 and the outer peripheral wall of the screen roller 6 is less than the thickness of a single piece of waste. During the operation of the screen roller 6, some waste separated by the screen roller 6 may adhere to the surface of the screen roller 6. The scraper 7 can scrape this non-metallic waste adhering to the screen roller 6 back onto the inclined plate 5. The distance between the end of the scraper 7 close to the screen roller 6 and the inclined plate 5 is less than the distance between the other end of the scraper 7 and the inclined plate 5. This arrangement makes the distance between the end of the scraper 7 away from the screen roller 6 and the inclined plate 5 larger, which can ensure the capacity of the scraper 7 and the inclined plate 5 to accommodate waste.

[0021] like Figure 1 and Figure 2 As shown, the conveying speed of the conveying component 2 is greater than the moving speed of the waste on the inclined plate 5. This setting allows the waste that has been separated on the inclined plate 5 to be carried away quickly when it falls onto the conveying component 2, making it less likely for the waste falling onto the conveying component 2 to overlap with the waste that fell onto the conveying component 2 previously. This effectively prevents the possibility of waste overlapping again. The inclined plate 5 has bends 8 welded to both sides of the inclined plate 5 and connected to the housing 1. Guide plates 9 inclined towards the center of the screen roller 6 are welded and fixed to the bends 8. Since there is a certain gap between the two ends of the screen roller 6 and the bends 8, the setting of the guide plates 9 allows some waste that may move along the connection between the bends 8 and the inclined plate 5 to move towards the center of the screen roller 6 under the guidance of the guide plates 9, so that this part of the waste can be separated by the screen roller 6. The inclined plate 5 is made of high manganese steel. High manganese steel has the advantage of good wear resistance. The inclined plate 5 made of this material can better adapt to the working environment of long-term friction with waste, so that the inclined plate 5 has a long service life.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
