DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1 - Figure 3 The utility model discloses a continuous processing and sorting device for waste aluminum materials from refrigerators, comprising a shell 1, a pneumatic selection chamber 2 is provided in the shell 1, a feed port 3 connected to the pneumatic selection chamber 2 is connected to one side of the top of the shell 1, a conveyor belt 4 is fixedly connected to the pneumatic selection chamber 2 below the feed port 3, a first copper outlet 5 is provided in the shell 1 on the side of the conveyor belt 4 away from the feed port 3, a roughing mechanism 6 is provided on the side of the pneumatic selection chamber 2 close to the first copper outlet 5, and a fine selection mechanism 7 is connected to the pneumatic selection chamber 2 below the conveyor belt 4.

[0023] In this embodiment, the refrigerator waste aluminum and waste copper are introduced into the air inlet selection chamber 2 through the feed port 3, and then the crushed waste will fall onto the conveyor belt 4 for transportation. When the conveyor belt 4 transports the waste to the first copper outlet 5, the first fan 61 is operated to cause the first air outlet pipe 62 to spray a high-pressure airflow to blow the waste, and then the waste aluminum, which is much lighter than the copper, can be blown up, and then the waste aluminum falls onto the discharge plate 71. At this time, the waste copper and waste aluminum can be preliminarily screened, and the waste copper from which the waste aluminum is removed will be discharged through the first copper outlet 5.

[0024] Because the size of the waste after the old refrigerator is crushed cannot be controlled, some of the smaller waste copper materials that are crushed will also be blown away by the airflow ejected from the first air outlet 62, so a screening plate 72 is provided on the discharge plate 71, and the screening plate 72 is supported by a torsion spring so that the screening plate 72 is flush with the discharge plate 71. When the copper material with a density much greater than that of the aluminum material slides onto the screening plate 72, because the copper material is heavier, the copper material presses down the screening plate 72 to move the screening plate 72 downward to open the through slot 8, thereby discharging the smaller copper material contained in the aluminum material, and performing a second screening on the aluminum material, and the aluminum material with the copper material removed will be discharged through the first aluminum outlet 9.

[0025] Finally, the copper material is mixed in the aluminum material, so when the copper material squeezes the screening plate 72 to open the through slot 8, some smaller aluminum materials will also fall with the copper material, and then the fallen mixed material will be affected by the airflow blown out by the second air outlet 733, so that the lighter aluminum material will be blown away, so that the aluminum material falling into the through slot 8 will be discharged through the second aluminum outlet 12, and the copper material will be discharged through the second copper outlet 11, so as to further separate the aluminum material and the copper material, so that the screening effect of refrigerator waste is better.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the rough selection mechanism 6 includes a first fan 61 and a first air outlet pipe 62. The first fan 61 is fixedly connected to the top of the shell 1. The output end of the first fan 61 is connected to the first air outlet pipe 62 through a connecting pipe. The first air outlet pipe 62 is inserted downwardly and obliquely into the shell 1 away from the side of the first fan 61, and extends into the air selection chamber 2.

[0027] In this embodiment, since the density of aluminum material is much smaller than that of copper material, a first fan 61 is provided. By controlling the air volume of the first fan 61, the wind force of the first air outlet pipe 62 can be adjusted, so that the wind can blow away the aluminum material and retain the heavier copper material, thereby achieving preliminary screening of the copper material and the aluminum material.

[0028] By inserting the first air outlet pipe 62 obliquely downward on the shell 1, the airflow blown out of the first air outlet pipe 62 can directly impact the conveyor belt 4, so that the high-speed airflow generates a reverse thrust on the conveyor belt 4, which can effectively blow out the aluminum material and improve the efficiency of the preliminary screening and the screening effect.

[0029] In a further preferred embodiment of the present invention, Figure 2As shown, the selecting mechanism 7 includes a discharge plate 71, a screening plate 72 and a recovery component 73. The discharge plate 71 is arranged on the lower side of the conveyor belt 4 and is fixedly connected to the inner wall of the air selection chamber 2. A through groove 8 is provided on the side of the discharge plate 71 away from the first air outlet pipe 62. The screening plate 72 is hinged on the side of the through groove 8 close to the first air outlet pipe 62. A torsion spring is connected at the hinge between the screening plate 72 and the discharge plate 71. A recovery component 73 is provided in the air selection chamber 2 below the through groove 8.

[0030] In this embodiment, although the wind control of the first air outlet duct 62 is blowing the aluminum material but not the copper material, some of the smaller broken copper materials will still be affected by the wind and blown away, resulting in smaller copper materials being mixed in the aluminum material after the initial screening. Therefore, a square through groove 8 is provided on the discharge plate 71 for smaller broken materials to pass through, so as to screen out the smaller copper materials.

[0031] However, there will be smaller copper materials and smaller aluminum materials, so when the copper materials are screened out, some of the aluminum materials will also be screened out, which will result in poor screening effect. Therefore, the screening plate 72 is hinged in the through slot 8, and the screening plate 72 is supported by the torsion spring at the same time, so that the screening plate 72 is flush with the discharge plate 71, so that the smaller aluminum materials can be discharged directly through the first aluminum outlet 9, while the heavier copper materials will press down the screening plate 72 and be discharged through the through slot 8, which can further improve the screening accuracy of the waste.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, the side of the discharge plate 71 away from the first air outlet pipe 62 is lower than the side of the discharge plate 71 close to the first air outlet pipe 62, so that the discharge plate 71 is tilted in the air selection chamber 2, and the first aluminum outlet 9 connected to the air selection chamber 2 is provided on the side of the shell 1 close to the bottom end of the discharge plate 71.

[0033] In this embodiment, in order to allow the waste aluminum blown away by the first air outlet 62 to be discharged normally, the discharge plate 71 is tilted in the air selection chamber 2, so that the waste falling on the discharge plate 71 can slide along the discharge plate 71 by utilizing the inclined surface and the traction of gravity, so that the waste can be automatically discharged through the first aluminum outlet 9.

[0034] In a further preferred embodiment of the present invention, Figure 2As shown, the recovery component 73 includes a partition 731, a second fan 732 and a second air outlet pipe 733, the inner bottom wall of the air selection chamber 2 is fixedly connected with two partitions 731, the two partitions 731 are respectively arranged on both sides below the through groove 8, the outer wall of the shell 1 is fixedly connected with the second fan 732, the second fan 732 is connected to the second air outlet pipe 733 through a connecting pipe, one of the side walls of the partition 731 is provided with a square groove 10, and the other partition 731 is connected to the second air outlet pipe 733 on the side away from the square groove 10.

[0035] In this embodiment, while the copper material presses down the screening plate 72 and falls through the through groove 8, the smaller aluminum material will also slide normally by gravity and fall together with the copper material, which will cause the fallen copper material to be mixed with less aluminum material. Therefore, a second fan 732 is provided on the outside of the shell 1, and a second air outlet pipe 733 is provided in the air selection chamber 2. The aluminum material can be blown away by the second air outlet pipe 733, so that the aluminum material and the copper material can be further screened.

[0036] Since the copper and aluminum materials are both in free fall, they will be blown by the wind. However, the copper material is heavier and therefore less affected by the wind. Therefore, in order to make the screening of the copper and aluminum materials more obvious, two partitions 731 are provided below the through groove 8, and one of the partitions 731 is provided with a square groove 10, so that the aluminum material can pass through the square groove 10 when blown by the wind, while the copper material cannot pass through the square groove 10 because it is less affected. As a result, the aluminum and copper materials are gathered together after being screened, thereby reducing the difficulty of subsequent cleaning.

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, a second copper outlet 11 and a second aluminum outlet 12 connected to the air selection chamber 2 are provided at the bottom of the shell 1. The second copper outlet 11 is arranged between the two partitions 731, and the second aluminum outlet 12 is arranged on the side of the square groove 10 away from the second air outlet pipe 733.

[0038] In this embodiment, by providing the second copper outlet 11 and the second aluminum outlet 12, the copper and aluminum wastes after fine screening can be directly discharged from the shell 1, so that the subsequent cleaning difficulty of the copper and aluminum wastes is reduced.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
