Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal screening, in particular to a nonferrous metal screening machine. Background Art

[0002] Nonferrous metals, also known as non-ferrous metals, are a general term for all metals other than iron, manganese and chromium. They are widely used in the fields of metallurgical engineering and metal materials science. During the processing of nonferrous metals, impurities in their raw materials need to be screened out.

[0003] Most of the existing non-ferrous metal screening devices are eddy current separators. The separator assembly is the core component of the equipment, which consists of a permanent magnetic roller, a material conveying system (including a material conveyor belt, a conveyor belt drive roller and a reduction motor). When working, a high-frequency alternating magnetic field is generated on the surface of the permanent magnetic roller. When conductive non-ferrous metals pass through the magnetic field, eddy currents are induced in the non-ferrous metals. This eddy current itself will generate a magnetic field in the opposite direction of the original magnetic field. Non-ferrous metals (such as copper, aluminum, etc.) will leap forward along their transportation direction due to the repulsive force of the magnetic field, thereby achieving separation from other non-conductors or non-metallic substances and achieving the purpose of separation.

[0004] However, due to the different sizes of non-ferrous metal materials, the induced eddy current strength is different, which leads to different forward distances, causing metal particles to enter the non-metallic collection box, thereby adding additional steps, lengthening the workflow, and material transfer and other work will also lead to increased labor costs.

[0032] like Figure 1-2As shown, an embodiment of the utility model provides a nonferrous metal screening machine, including a box body 100, a feed hopper 110 is provided on the top of the box body 100, and the upper end of the feed hopper 110 has an opening connected to the outside, and materials enter from the opening of the feed hopper 110, and a discharge port is provided at the bottom of the box body 100, and a crushing mechanism and a sorting mechanism are arranged in the box body 100 from top to bottom, wherein the crushing mechanism includes two crushing rollers 210, a crushing motor 220, two transmission gears 230 and a screening plate 240; the two crushing rollers 210 are rotatably arranged on the box body 100 and are parallel to each other, and are used to crush the materials; the crushing The motor 220 is arranged on the outside of the box body 100 and its output end is fixedly connected to one end of the roller shaft of a crushing roller 210; the two transmission gears 230 are respectively arranged at one end of the roller shaft of the two crushing rollers 210 away from the crushing motor 220 and are meshed with each other for transmission; the screening plate 240 is arranged in the box body 100 and is located below the crushing roller 210, and is used to filter and sort the crushed materials. Specifically, the surface of the screening plate 240 is provided with evenly distributed screening holes, which can screen the ore put onto the screening plate 240, so that the material that meets the size requirements passes through the screening holes, while the larger material is retained on the screening plate 240.

[0033] In the embodiment of the utility model, by arranging a crushing mechanism and a sorting mechanism in the box 100, the material is first crushed by the crushing mechanism to make its particle size as uniform as possible, and then screened by the screening plate 240 to screen out particles of suitable diameter, and then sorted by the sorting mechanism, thereby improving work efficiency.

[0034] like Figure 1-2 As shown, in the embodiment of the utility model, the screening plate 240 is arranged at an angle; a return pipe 310 is arranged on the outer side of the box body 100 corresponding to the lower end of the screening plate 240, and the return pipe 310 is connected to the box body 100, so that the ore sorted by the screening plate 240 can enter the return pipe 310, and the large volume of material retained on the screening plate 240 can be collected through the return pipe 310 for secondary processing.

[0035] like Figure 1-2As shown, in the embodiment of the utility model, a conveying screw 320 is provided in the return tube 310; a return motor 330 is provided at the bottom end of the return tube 310, which is transmission-connected to the conveying screw 320 inside the return tube 310, and is used to drive the conveying screw 320 to rotate so as to convey the screened ore to the feed hopper 110. By starting the return motor 330, the return motor 330 drives the conveying screw 320 to rotate, so as to convey the material that is not screened out by the screening plate 240 to the feed hopper 110 (smaller materials fall through the sieve holes, while larger materials remain on the plate and are conveyed to the feed hopper 110 under the action of gravity), and then are crushed by the crushing mechanism so that the particle size meets the requirements of the screening plate 240, so that the subsequent sorting mechanism can perform sorting.

[0036] like Figure 1-2 As shown, in the embodiment of the utility model, an inclined conveying pipe 340 is provided on the top of the return pipe 310, and the conveying pipe 340 is connected to the feed hopper 110.

The two material guide plates 120 are arranged to be inclined along the axial direction of the box body 100 so as to guide the materials during the feeding process, so that the materials can accurately enter the gap between the two crushing rollers 210, thereby improving the crushing effect.

By starting the vibration motor 420, the vibration motor 420 drives the screening plate 240 to move up and down along the hinge, so that the material on the screening plate 240 can move along the inclined surface and finally enter the return pipe 310, thereby improving its circulation efficiency and avoiding clogging of the screen holes.

[0039] like Figure 1-2 As shown, in the embodiment of the utility model, two guide plates 130 are obliquely provided below the screening plate 240, and the two guide plates 130 form a material guiding channel with an opening gradually decreasing from top to bottom, and the sorting mechanism is arranged below the material guiding channel. Specifically, the two guide plates 130 have different inclination angles so that their material guiding channels are located on one side of the sorting mechanism, and the material guiding channels of the guide plates 130 facilitate the materials to fall into the sorting mechanism in a concentrated manner for further sorting.

[0040] like Figure 1-2 As shown, in an embodiment of the utility model, the sorting mechanism includes a conveyor belt 510, a permanent magnet roller 520 is arranged in the conveyor belt 510, and the permanent magnet roller 520 is arranged away from the material guide channel; a dividing plate 140 is provided at the discharge port, and the dividing plate 140 divides the discharge port into a non-metallic discharge port 150 and a metal discharge port 160, and the non-metallic discharge port 150 is arranged close to the permanent magnet roller 520, wherein the top of the dividing plate 140 is an arc-shaped structure so that non-ferrous metals can slide out of the metal material outlet, and the materials screened out on the conveyor belt 510 are sorted into non-ferrous metals and non-metals by the permanent magnet roller 520, and then the materials are facilitated to fall to the corresponding discharge port through the dividing plate 140.

[0041] In the embodiment of the utility model, the conveyor belt 510 and the permanent magnet roller 520 are technologies well known to those skilled in the art, so their specific structures are not described in detail here.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
