[0043] Combination Figures 1 to 3 As shown, the present application provides a specific gravity separator, which includes: a frame 30; a feed bin 10, which is arranged on the frame 30, and the feed bin is provided with a feed port 110, a heavy material collection port 120, a light material diversion port 190 and a feed pipe 180; a conical cylinder 20, which is arranged on the frame 30, and the conical cylinder 20 is provided with a light material collection port 210; an exhaust fan 40, which is arranged on the conical cylinder 20, and the exhaust fan 40 has an exhaust port 410 and an air outlet 420, and the air outlet 420 is connected to the cone 20; an exhaust pipe 50, one end of which is connected to the light material diversion port 190, and the other end is connected to the exhaust port 410.

[0044] Compared with the prior art, the present application puts the material into the feed bin from the feed port, and the material is divided into heavy material and light material. The heavy material is discharged through the heavy material collecting port under the action of its own gravity, and the light material enters the conical cylinder through the exhaust pipe under the action of the exhaust fan, and is then discharged through the light material collecting port under the action of gravity, thereby realizing the sorting of materials by weight. The present application integrates the feed bin, conical cylinder and exhaust fan into the frame to reduce the occupied space and has a simple structure.

[0045] Specifically, by putting the material to be sorted into the feed port 110 (the material to be sorted includes heavy material and light material, and the definition of heavy material and light material depends on the power of the exhaust fan. For example, when the power of the exhaust fan is b kilowatts, the mass of the heavy material is defined as more than a gram, and the mass of the light material is less than a gram), the material comes into contact with the airflow of the exhaust fan 40 during the falling process, and the heavy material falls to the heavy material collection port 120 due to gravity; and the light material is transported to the conical cylinder through the exhaust pipe under the action of the exhaust fan, and then falls to the light material collection port 210 in the conical cylinder due to gravity, thereby realizing the sorting of materials of different weights.

[0046] In one embodiment, the exhaust fan 40 is disposed at the top of the conical cylinder 20 to reasonably utilize the longitudinal space. Moreover, due to the different weights of the materials put in, the exhaust fan is disposed at the top of the conical cylinder and connected to the conical cylinder, and the exhaust fan draws air, generates suction, and sucks the light materials into the exhaust pipe at the light material separation port 190;

[0047] Specifically, after the material is dropped into the feed port 110, the heavy material will fall to the heavy material collection port, while the light material will be sucked into the exhaust pipe 50 by the exhaust fan 40 during the falling process, and will enter the conical cylinder 20 connected to the exhaust pipe 50 with the wind, and finally fall to the light material collection port 210.

[0048] In one embodiment, the feed bin is also provided with a reflux port; the conical cylinder is provided with light materials and an air inlet; the specific gravity separator includes a connecting pipe, one end of which is connected to the air inlet and the other end is connected to the reflux port.

[0049] Specifically, the gravity separator in this embodiment adopts sealed feeding, connecting the conical cylinder 20 and the feed bin 10 to form a closed connection, so that the airflow of the exhaust fan 50 can circulate in the gravity separator, and at the same time can effectively prevent foreign matter such as dust from falling into the gravity separator, thereby improving the purity of material sorting.

[0050] In one embodiment, since some materials may stick to each other during the feeding process, the feed pipe includes multiple bending sections, and the bending sections are inclined between two adjacent sections to increase the material passing distance, thereby facilitating the breaking up and spreading of the fed materials.

[0051] In one embodiment, the specific gravity separator includes a discharge mechanism, which is arranged at the feed port, and the discharge mechanism includes a discharge motor 150, a discharge hopper 160 and a discharge shaft 170. The discharge shaft is arranged in the discharge hopper, and a feeding agitator is provided on the discharge shaft, wherein the discharge motor drives the discharge shaft to move to realize the feeding function.

[0052] In one embodiment, the feed bin is provided with an observation window 140 to facilitate observation of the material being put in and the material entering the feed bin 10 .

[0053] In one embodiment, a first collecting area is provided below the feed bin; the first collecting area is provided corresponding to the heavy material collecting port so as to place a corresponding collecting bag to collect the material.

[0054] In one embodiment, the specific gravity separator includes a discharge mechanism, which is arranged at the light material collection port, and the discharge mechanism includes a discharge motor 240, a discharge hopper 230 and a discharge shaft. The discharge shaft is arranged in the discharge hopper, and a discharge stirring blade is provided on the discharge shaft, wherein the discharge motor drives the discharge shaft to move to realize the discharge function.

[0055] In one embodiment, a second collecting area is provided below the conical barrel 20; the second collecting area is provided corresponding to the light material collecting port 210 so as to place a corresponding collecting bag to collect the material.

[0056] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
