[0016] A gold mining slag screening device comprises four support columns 1, and a rectangular frame 2 is fixed to the four support columns 1.

[0017] Figure 1-Figure 3 A support plate 9 is fixedly arranged on the bottom end of the four support columns 1, and a reinforcing rib 10 for reinforcing the device is fixed between the support plate 9 and the side wall of the support column 1. The support plate 9 increases the contact area between the support column 1 and the ground, increases the force-bearing area of ​​the device, and ensures the overall stability of the device. The reinforcing rib 10 can further improve the connection firmness.

[0018] Four support columns 1 are evenly distributed at the corners of the rectangular frame 2, and shock absorbers 3 are fixedly arranged at each corner of the upper end surface of the rectangular frame 2, and a shell 4 is fixedly arranged on the top of the four shock absorbers 3, and a plurality of transport units are fixedly arranged on the side wall of the shell 4, and each transport unit includes two rotating shafts 5 rotatably connected to the shell 4, and the two rotating shafts 5 are connected through a conveyor belt transmission, and a motor 6 is fixedly arranged on the shell 4, and the output end of the motor 6 is fixedly connected to the rotating shaft 5, and each transport unit is inclined with one rotating shaft 5 higher and the other rotating shaft 5 lower, and a transmission mechanism is arranged between different transport units.

[0019] The transmission mechanism includes a gear 11 fixed on the lower vertical shaft 5 in the upper transport unit, and a gear 2 12 fixed on the higher end shaft 5 of another lower transport unit and meshing with the gear 1 11. Gear 1 11 and gear 2 12 realize the transmission between the upper and lower shafts 5 and control the transport rate of the material on the conveyor belt.

[0020] Reference Figure 2-Figure 4 A plurality of magnets 13 of different specifications are fixedly arranged in the outer shell 4, and each magnet 13 is distributed in the space surrounded by the conveyor belts in different transport units. Through the plurality of magnets 13 with different magnetic forces, when the conveyor belt transports the slag material, different magnets 13 can adsorb and process different metal slags, thereby classifying and collecting them.

[0021] Reference Figure 1-Figure 3 A feed hopper 7 is fixedly arranged on the top of the shell 4, and a discharge port 8 is opened on the side wall of the shell 4. A plurality of scrapers 14 are fixedly arranged on the shell 4, and each scraper 14 is fitted with the lower end surface of the conveying belt, and the cross section of each scraper 14 is a conical setting with one end small and the other end large. The scraper 14 is used to scrape off the slag attached to the bottom of the conveying belt, so that the conveying belt can continuously adsorb and classify the slag.

[0022] Reference Figure 2-Figure 4 The feed hopper 7 is arranged in a funnel shape with a large top and a small bottom, which facilitates the feeding of materials into the feed hopper 7 .

[0023] like Figure 1 , 3 4, a discharge port corresponding to the transport unit is opened on the side wall, and the discharge ports are located at different heights. When the device is in operation, there are some impurities on the conveyor belt that cannot be completely screened, and the remaining impurities are accumulated at the bottom of the conveyor belt. The opened discharge port can discharge and process them. Each discharge port has a material receiving machine to collect them (the material receiving machine belongs to the existing device and is omitted in the figure).

[0024] The operation of the device is as follows: the ore enters from the feed hopper 7 and first falls onto the uppermost conveyor belt. Multiple transport units transport the ore step by step. The magnet adsorbs the slag, and under the action of the scraper 14, it falls onto the transport unit of the next layer, completing the layer-by-layer screening.
