Description

Technical Field

[0001] This utility model relates to the field of waste recycling and processing technology, and in particular to a sorting device. Background Technology

[0002] With the surge in electronic waste and industrial waste, the efficient recycling of mixed copper and aluminum metals has become a key link in resource recycling. Currently, the metal recycling industry generally adopts mechanical crushing combined with physical sorting technology. Among them, the hammering process can crush metal into uniform small spheres, which facilitates subsequent sorting and processing.

[0003] Currently, the industry mainly uses three sorting schemes: First, eddy current separators, which use alternating magnetic fields to generate eddy currents to separate non-ferrous metals, achieving a sorting purity of up to 95%, but the equipment cost is as high as 500,000 yuan or more; second, vibrating screen density sorting, which uses vibrating screens with different inclination angles to separate copper and aluminum, with an equipment cost of about 100,000 yuan, but a sorting efficiency of only about 70%; and third, manual sorting, which relies entirely on workers' visual identification, with a daily processing capacity of no more than 2 tons, and labor costs accounting for 40%. In actual use, the above methods have the following drawbacks: eddy current separators have strict requirements on material particle size and require a precision feeding system; vibrating screen sorting is prone to causing the oxide layer on the surface of metal balls to fall off, resulting in secondary pollution; the sorting purity is unstable; and manual sorting has problems such as high labor intensity and poor sorting consistency. Utility Model Content

[0004] Therefore, it is necessary to provide a sorting device to address the issues of material particle size sensitivity, unstable sorting purity, and high dependence on manual labor.

[0005] A sorting device includes a base and a sorting box mounted on one side thereof. A hammer mill and a vibrating feeder are respectively mounted on the top of the base. The device also includes a sorting mechanism disposed inside the sorting box and used for sorting copper and aluminum materials. The sorting mechanism includes a guide plate and an exhaust box below it. A set of equally spaced guide grooves are provided on the guide plate. The guide plate forms a 30-degree angle with the top of the sorting box.

[0006] In one embodiment, the sorting box has two collection boxes inside, with an angle of 22 degrees between the two collection boxes, and one side of the collection box extends to the outside of the sorting box and is provided with an opening and closing door.

[0007] In one embodiment, the baffle is mounted to the inner wall of the sorting box via a hinge and secured with bolts.

[0008] In one embodiment, a material collection trough communicating with the guide channel is provided on one side of the guide plate, and a baffle plate is installed on the guide plate.

[0009] In one embodiment, the hammer mill is equipped with a drive motor, a screen and a set of hammers, the hammers being circumferentially distributed along the axis of the output shaft of the drive motor, and the hammers being made of tungsten steel.

[0010] In one embodiment, a high-pressure fan is mounted on the base, and the high-pressure fan is connected to one side of the exhaust box.

[0011] In one embodiment, the vibratory feeder is located below the discharge port of the hammer mill, and the guide plate is located below the discharge end of the vibratory feeder.

[0012] Beneficial effects 1. By setting up a guide plate and using the high-pressure airflow discharged from the exhaust box, precise inertial separation of copper and aluminum balls is achieved, reducing the phenomenon of oxide layer peeling due to excessive collision between materials, improving sorting purity, and the sorting is automated throughout the process, effectively reducing reliance on manual labor. Users can also adjust the angle of the guide plate to adapt to materials of different particle sizes and relax the particle size requirements of the materials. 2. By setting up guide channels and collection channels, materials can be diverted and guided to ensure uniform material discharge, improve the effectiveness of airflow sorting, and ensure the consistency of copper and aluminum ball sorting.

[0021] The following is combined with Figures 1-4 This invention describes a sorting device.

[0022] In one embodiment, a sorting device includes a base 100 and a sorting box 200 mounted on one side thereof. A hammer mill 110 and a vibrating feeder 120 are respectively mounted on the top of the base 100. The device also includes a sorting mechanism 300, which is disposed inside the sorting box 200 and is used to sort copper and aluminum materials. The sorting mechanism 300 includes a guide plate 310 and an exhaust box 320 located below it. A set of guide grooves 311 are arranged at equal intervals on the guide plate 310. The guide plate 310 and the top of the sorting box 200 form a 30-degree angle.

[0023] like Figure 1 and Figure 3 As shown, the sorting box 200 has two collection boxes 210 inside, with an included angle of 22 degrees between the two collection boxes 210. One side of the collection box 210 extends to the outside of the sorting box 200 and is equipped with an opening and closing door.

[0024] In this embodiment, the copper and aluminum materials are crushed into spherical shapes of corresponding diameter by a hammer mill 110. Then, a vibrating feeder 120 is used to transport the materials to a guide plate 310. The materials fall along the guide plate 310 under their own weight. Since the density of copper balls is greater than that of aluminum balls, during the falling process, a high-pressure blower 130 blows gas along the exhaust box 320 towards the materials, causing the aluminum balls to be blown away. As a result, the aluminum balls deviate during the descent and enter the interior of the inclined collection box 210. Subsequently, the copper and aluminum fall directly into another collection box 210, completing the sorting and collection operation.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the guide plate 310 is installed to the inner wall of the sorting box 200 via a hinge and fixed with bolts.

[0026] Users can adjust the angle of the guide plate 310 according to the type of material to be sorted, thereby providing different degrees of inertia when the material falls, to complete the corresponding sorting requirements, making it more versatile.

[0027] like Figure 2 and Figure 3 As shown, a material collection trough 312 communicating with the guide channel 311 is provided on one side of the guide plate 310, and a baffle plate 313 is installed on the guide plate 310.

[0028] The material discharged from the vibrating feeder 120 is received by the material collection trough 312 and blocked by the baffle plate 313 to ensure that the accumulated material can only be discharged along the corresponding guide trough 311, thus ensuring uniform discharge, reducing subsequent sorting pressure and improving sorting accuracy.

[0029] like Figure 1 and Figure 4As shown, the hammer mill 110 is equipped with a drive motor, a screen and a set of hammers 111. The hammers 111 are distributed in a circle along the axis of the output shaft of the drive motor. The hammers 111 are made of tungsten steel.

[0030] A drive motor is used to operate the hammer 111. After being struck by the hammer 111, the material that meets the standard is discharged along the screen to the discharge port. It should be noted that, since the hammerhead 111 is made of tungsten steel, its hardness during use is ≥89HRA. Through the synergistic effect of the tungsten steel hammerhead 111 group and the guide plate 310 with a specific tilt angle, the precise inertial separation of copper and aluminum balls is achieved, improving the sorting purity and significantly enhancing the adaptability of particle size materials.

[0031] like Figure 1 As shown, a high-pressure blower 130 is installed on the base 100, and the high-pressure blower 130 is connected to one side of the exhaust box 320.

[0032] The high-pressure blower 130 extracts the outside air and pressurizes it out through the exhaust box 320. The air is then blown towards the copper and aluminum materials to complete the sorting operation. It should be noted that the high-pressure blower 130 in this application is a 9-26 type blower with a wind pressure ≥12kPa. The horizontal airflow generated blows the material at a speed of 15m / s. High-pressure airflow separation replaces traditional electrostatic separation, avoiding the influence of material moisture content on the separation effect, and at the same time reducing unit energy consumption.

[0033] like Figure 1 As shown, the vibrating feeder 120 is located below the discharge port of the hammer mill 110, and the guide plate 310 is located below the discharge end of the vibrating feeder 120.

[0034] The vibrating feeder 120 receives the material discharged from the hammer mill 110 and then guides it onto the guide plate 310 in sequence to complete the material conveying. It should be noted that the feeding rate of the vibratory feeder 120 in this application is 2 kg / min.

[0035] Working principle: The metal scrap is fed into the hammer mill 110. The hammer mill 110 is started to crush the scrap metal into spherical shapes with a diameter of 3-5mm. At the same time, the guide plate 310 is adjusted to a 30-degree inclination angle and the high-pressure blower 130 is turned on. The material is conveyed at a fixed frequency through the vibrating feeder 120. Then, the high-pressure blower 130 drives the copper and aluminum balls falling during the process and guides the copper and aluminum balls into the corresponding collection boxes 210 respectively to complete the sorting. Afterwards, the user can clean the material collected in the collection box 210 periodically.

[0036] It should be noted that the hammer mill 110 and vibratory feeder 120 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the hammer mill 110, vibratory feeder 120 and high-pressure blower 130 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
