Description

Technical Field

[0001] The present invention relates to the field of mineral processing equipment, in particular to a screening device for mineral processing. Background Art

[0002] Rocks containing useful minerals and worth mining, especially galena, pyrite, hematite, and chalcopyrite that can be used as detectors. Any natural aggregate of minerals in the earth's crust from which metals or other mineral products necessary for the national economy can be extracted on an industrial scale under the conditions of modern technological and economic levels is called ore.

[0003] When ore is mined, the raw materials mined are of different sizes. At this time, the minerals need to be screened into specifications of different sizes to meet different usage requirements. However, the existing mineral processing equipment is large in size and complex in structure, which is very inconvenient. Summary of the invention

[0016] The following are examples and the attached Figure 1 , the technical solution of the present invention is further specifically described.

[0017] A screening device for mineral processing comprises a barrel body 1 with a cover plate 2 on the top, wherein a discharge pipe is provided at the bottom of the barrel body 1, and a feed pipe is provided at the top of the barrel body 1:

[0018] A plurality of groups of material guide hoppers 3 are arranged in parallel in the upper and lower parts of the barrel body 1, wherein an umbrella-shaped filter cover 4 is arranged in the barrel body 1 above each group of material guide hoppers 3, and the upper and lower groups of filter covers 4 are connected by vertical rods 5, and a motor 6 connected to the vertical rod 5 is arranged on the cover plate 2, and a discharge port 7 is arranged on the side wall of the barrel body 1 above the filter cover 4, wherein a cylinder 8 covering the feed port 7 is arranged on the barrel body 1, and any two adjacent groups of cylinders 8 in the upper and lower parts are connected by connecting rods 9, and a collecting box 10 corresponding to the discharge port 7 is arranged on the outer wall of the cylinder 8, and a hydraulic rod I11 connected to the cover plate 2 and a hydraulic rod II12 connected to the cylinder 8 are also arranged on the outer wall of the barrel body 1.

[0019] In this embodiment, a support for fixing a hydraulic rod I11 is arranged on the outer wall of the barrel body 1, wherein the hydraulic rod I11 is located outside the cylinder 8, and the hydraulic rod I11 is staggered with the connecting rod 9 and the discharge port 7.

[0020] like Figure 1 As shown, multiple groups of inclined rods 13 connected to the vertical rods 5 are arranged at an angle downward at the bottom of the filter cover 4. The inclined rods 13 play a supporting and fixing role on the edge of the suspended end of the filter cover 4.

[0021] like Figure 1As shown, multiple groups of serpentine baffles 14 are arranged along the inclined surface on the top surface of the filter cover 4. The serpentine baffles 14 slow down the flow rate of the material from the middle of the top of the filter cover 4 to its edge, and at the same time, the filter cover 4 that is turned to the baffles 14 drives the material above it to rotate for screening.

[0022] In this embodiment, the bottom edge of the filter cover 4 is located at the top of the corresponding guide hopper 3.

[0023] In this embodiment, the aperture of the side wall of the upper filter cover 4 is larger than the aperture of the side wall of the lower filter cover 4.

[0024] When in use, the material is introduced into the filter cover 4 directly above. At this time, the motor 6 drives the upper and lower multiple groups of filter covers 4 to rotate through the vertical rod 5, and then screens the material above them. The qualified materials are screened through the corresponding side wall apertures of the filter cover 4, while the unqualified materials are deposited above them. At the same time, the guide hopper 3 guides the screened materials above them, so that they flow to the middle of the top of the filter cover 4 below, and then it is convenient for the materials to flow from the middle of the filter cover 4 to its edge, so that the materials are screened along the rotating side wall apertures of the filter cover 4 during this flow process;

[0025] At the same time, the hydraulic rod I11 drives the cover plate 2 to drive the vertical rod 5 and the filter cover 4 to move back and forth up and down, so as to achieve the purpose of shaking the filter cover 4, thereby accelerating the screening efficiency of the material above it, and the maximum upward movement of the filter cover 4 is to the lower part of the upper discharge port 7, to prevent the filter cover 4 from moving up to the upper part of the corresponding discharge port 7, causing the material above the filter cover 4 to flow into the discharge port 7, and then flow to the lower filter cover 4, resulting in the filter cover 4 being unable to effectively screen the material, so that the excess material will also flow to the lower filter cover 4;

[0026] When it is necessary to discharge the filtered material, the hydraulic rod I11 drives the cover plate 2 and the vertical rod 5 to drive the filter cover 4 to move up to the corresponding position below the discharge port 7, and the hydraulic rod II12 drives the cylinder 8 and the connecting rod 9 to drive the corresponding cylinder 8 to move to the position below the discharge port 7, and then the discharge port 7 is opened. At this time, the material above the filter cover 4 will flow along its inclined surface to its edge, and finally flow into the collection box 10 through the discharge port 7 to facilitate the collection and recovery of the filtered material. Of course, in the above process, the motor 6 can drive the vertical rod 5 to drive the filter cover 4 to rotate, so that its different positions are all rotated to the discharge port 7, so that the material above it can be discharged through the discharge port 7.

[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
