[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a screening device for recovering metal from vanadium tailings waste, comprising: a primary screening mechanism 1 and a fine screening mechanism 2; the fine screening mechanism 2 includes a connecting plate 201, a rotating seat 202 fixedly installed on one side of the connecting plate 201, a magnetic separator 203 rotatably connected to one end of the rotating seat 202, a rotating rod 204 passing through the interior of the connecting plate 201, a connecting rod 205 fixedly installed on the outer wall of the rotating rod 204, one end of the connecting rod 205 fixedly connected to the inner wall of the magnetic separator 203, a connecting channel 206 fixedly connected to one side of the rotating seat 202, an airflow separator 207 fixedly connected to one end of the connecting channel 206, a fine particle outlet 208 and an air inlet 209 respectively connected to the outer wall of the airflow separator 207, and a vanadium powder outlet 210 provided at the bottom of the airflow separator 207; the connecting rod 205 is rotated by a rotating motor 110, causing the connecting rod 205 to rotate inside the connecting plate 201. Rotation occurs because the connecting rod 205 connects the rotating rod 204 and the magnetic separator 203. As the rotating motor 110 drives the rotating rod 204 to rotate, both ends of the magnetic separator 203 also rotate inside the clamping plate 109 and the rotating base 202. This rotational screening removes magnetic metal particles from the vanadium tailings waste particles. The connecting channel 206 connects the rotating base 202 and the air classifier 207. After magnetic screening, the vanadium tailings waste particles enter the air classifier 207 for further separation. By connecting the air inlet 209 to the external air duct and setting the wind speed of the external fan, the vanadium tailings waste particles enter the air classifier 207 through the connecting channel 206 and fall due to gravity. The heavier metal particles in the waste are not affected by the wind and continue to fall to the vanadium powder outlet 210, where they are collected. The lighter non-metallic particles are discharged from the air classifier 207 through the fine particle outlet 208.

[0019] like Figure 3 As shown, the primary screening mechanism 1 includes a screening box 101, and a cover plate 102 is provided on the top of the screening box 101. The top of the cover plate 102 is connected to the feed hopper 103. By movably setting the cover plate 102 and the screening box 101, it is convenient to disassemble and clean the inside of the screening box 101, and at the same time, it is convenient to perform regular maintenance on the screening structure set inside the screening box 101.

[0020] like Figure 3As shown, a set of insert plates 104 are slidably arranged inside the screening box 101. A first screen plate 105 and a second screen plate 106 are respectively arranged between the insert plates 104. The first screen plate 105 is located on top of the second screen plate 106, and the diameter of the screen holes of the first screen plate 105 is larger than that of the screen holes of the second screen plate 106. By arranging the two-stage screening structure in a movable manner, the first screen plate 105 and the second screen plate 106 are used to screen vanadium tailings waste particles of different particle sizes in a graded manner, so as to avoid the particle size being too large and affecting the screening effect.

[0021] like Figure 3 As shown, a vibration motor 107 is fixedly installed on the outer wall of the screening box 101, and a guide plate 108 is installed on the inner wall of the screening box 101. The guide plate 108 is located at the bottom of the second screen plate 106. The installation of the vibration motor 107 facilitates the improvement of screening efficiency, and the setting of the guide plate 108 facilitates the introduction of vanadium tailings waste particles screened by the first screen plate 105 and the second screen plate 106 into the interior of the magnetic separator 203 for the next screening operation.

[0022] like Figure 2 and Figure 3 As shown, a card plate 109 is fixedly installed at the bottom of the screening box 101, and a rotating motor 110 is fixedly installed on one side of the card plate 109. By setting the card plate 109, it is easy to connect the magnetic separator 203. The rotating motor 110 drives the magnetic separator 203 to rotate, and the magnetic metal particles in the vanadium tailings waste particles are screened.

[0023] like Figure 1 and Figure 2 As shown, the connecting plate 201 is fixedly connected to the screening box 101, and the magnetic separator 203 is rotatably connected to the clamping plate 109. By fixing the connecting plate 201 to the screening box 101, the magnetic separator 203 is supported. The magnetic separator 203 and the clamping plate 109 are connected to support it without affecting the rotation and screening of the magnetic separator 203.

[0024] like Figures 1-4 As shown, the rotating rod 204 passes through the card plate 109, and one end of the rotating rod 204 is fixedly connected to the output end of the rotating motor 110. By connecting the rotating rod 204 to the rotating motor 110, the rotating motor 110 outputs power to drive the magnetic separator 203 to rotate and screen magnetic metal particles.

[0025] The method of use and working principle of this device: When using this device, firstly, the vanadium tailings waste residue is poured into the inside of the feed hopper 103, and at the same time, the vibration motor 107 is started. The vibration motor 107 drives the screening box 101 to vibrate. The first screen plate 105 and the second screen plate 106 are used to screen vanadium tailings waste residue particles of different particle sizes. Large vanadium tailings waste residue particles are discharged from one end of the first screen plate 105 and the second screen plate 106 respectively, thus separating the large vanadium tailings waste residue particles. Secondly, the vanadium tailings waste particles screened by the first screen plate 105 and the second screen plate 106 are guided by the guide plate 108 and enter the interior of the magnetic separator 203. The rotating motor 110 drives the connecting rod 205 to rotate, so that the connecting rod 205 rotates inside the connecting plate 201. Since the connecting rod 205 connects the rotating rod 204 and the magnetic separator 203, when the rotating motor 110 drives the rotating rod 204 to rotate, both ends of the magnetic separator 203 also rotate inside the clamping plate 109 and the rotating seat 202. The rotating process screens the magnetic metal particles in the vanadium tailings waste particles. Then, by setting the connecting channel 206 to connect the rotating base 202 and the air classifier 207, the vanadium tailings waste particles after magnetic screening enter the air classifier 207 for the next step of separation. By connecting the air inlet 209 to the external air duct and setting the wind speed of the external fan, the vanadium tailings waste particles enter the air classifier 207 through the connecting channel 206 and fall due to gravity. The heavier metal particles in the waste are not affected by the wind and continue to fall to the vanadium powder outlet 210 and are collected. The lighter non-metallic particles are discharged from the air classifier 207 through the fine particle outlet 208. Finally, the magnetic metal particles inside the magnetic separator 203 are periodically cleaned by shutting down the machine. After the machine is shut down, the magnetic metal particles are discharged from the vanadium powder outlet 210 of the airflow separator 207, thus completing the screening of magnetic and non-magnetic metals.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
