Description

Technical Field

[0001] This utility model relates to the field of copper-sulfur ore separation and processing technology, specifically to a device for differentiated processing of copper-sulfur middlings. Background Technology

[0002] Copper-sulfur ore is a complex ore type formed by the coexistence of copper and sulfide minerals. The copper concentrate obtained from it is not only a core source of global copper resources, but the sulfur in copper-sulfur ore can also be recovered as sulfur concentrate for use in chemical, metallurgical, and other fields. In the processing of copper-sulfur ore, flotation is typically used to separate the copper and sulfide minerals. This involves impregnating the ground copper-sulfur ore, preferentially floating copper under low alkalinity conditions, and then floating sulfur in the tailings, thus achieving differentiated processing of the copper-sulfur ore.

[0003] In real-world applications, when separating crushed copper-sulfur minerals by flotation, the minerals are often directly fed into the flotation cell. However, the varying particle sizes of the crushed copper-sulfur minerals can affect the recovery rate under the same conditions and increase reagent usage. Therefore, a device with differentiated processing capabilities for copper-sulfur middlings is needed. Utility Model Content

To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a device for differentiated treatment of copper-sulfur middlings ore, comprising:

[0006] The processing box has flotation cells on both sides of the top of the processing box, and two connecting seats are fixedly provided in the middle of the top of the processing box.

[0007] A screening assembly includes a screening frame, with elastic blocks engaged at the bottom of both sides of the screening frame. A screening plate is provided at the opposite ends of two elastic blocks. A vibration motor is fixedly installed on one side of the bottom of the screening plate. Support rods are fixedly installed on the four sides of the bottom of the screening frame.

[0008] Furthermore, the width of the screening plate is longer than the width of the screening frame, and the length of the screening plate is shorter than the width of the inner wall of the guide plate.

[0009] Furthermore, one end of each side of the screening plate is connected to the bearings on both sides of the inner wall of the screening frame.

[0010] Furthermore, rod seats are fixedly provided at the top of both sides of the screening frame, and sliding rods are provided through the top of the two rod seats. Springs are sleeved on the bottom of the outer walls of the two sliding rods.

[0011] Furthermore, each of the two connecting seats has a through groove on its opposite side, and the upper and lower ends of the two through grooves are respectively fixedly connected to the upper and lower ends of the two slide rods.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a device for differentiated treatment of copper-sulfur middlings ore, comprising:

[0026] The processing box 1 has flotation tanks 11 on both sides of the top of the processing box 1, and two connecting seats 2 are fixedly installed in the middle of the top of the processing box 1.

[0027] The processing box 1 is used for mineral flotation. The flotation cell 11 contains flotation reagents and has a discharge port at its bottom.

[0028] Screening assembly 3 includes a screening frame 31. Elastic blocks 32 are engaged at the bottom of both sides of the screening frame 31. A screening plate 33 is provided at the opposite end of the two elastic blocks 32. A vibration motor 34 is fixedly provided on one side of the bottom end of the screening plate 33. Support rods 35 are fixedly provided on the four sides of the bottom end of the screening frame 31. A guide plate 36 is provided at the bottom end of the four support rods 35. The inner bottom end of the guide plate 36 is inclined downward.

[0029] Both sides of the screening frame 31 have slots at the bottom that are compatible with the elastic block 32. The screening plate 33 has several screening holes. The vibration motor 34 is a YZU model, which is used to provide the vibration force required for the up and down vibration screening of the screening plate 33. A control panel is installed on one side of the processing box 1. The vibration motor 34 is electrically connected to an external power supply through the control panel. The guide plate 36 is used to guide the screened minerals into the flotation cell 11.

[0030] The width of the screening plate 33 is longer than the width of the screening frame 31, and the length of the screening plate 33 is shorter than the width of the inner wall of the guide plate 36.

[0031] One end of each side of the screening plate 33 is connected to the bearings on both sides of the inner wall of the screening frame 31;

[0032] This facilitates the connection and support of the screening plate 33, and also makes it easy to open and rotate the screening plate 33, which is convenient for feeding the minerals above the screening plate 33.

[0033] The top of both sides of the screening frame 31 is fixedly provided with rod seats 37, and the top of the two rod seats 37 is provided with sliding rods 38, and the bottom of the outer wall of the two sliding rods 38 is fitted with springs 39.

[0034] The rod seat 37 and the slide rod 38 are slidably engaged, and a rubber sleeve with damping and elastic functions is bonded to the contact position between the rod seat 37 and the slide rod 38, so that the spring 39 will not continue to extend and rebound after contraction.

[0035] Each of the two connecting seats 2 has a through groove 21 on one side of its opposite side, and the upper and lower ends of the two through grooves 21 are fixedly connected to the upper and lower ends of the two slide rods 38 respectively.

[0036] The bottom end of the through groove 21 is fixedly connected to the bottom end of the spring 39, and the top end of the spring 39 is fixedly connected to the bottom end of the rod seat 37.

[0037] Working principle: Flotation reagents with different concentrations are injected into two flotation cells 11 respectively. Then, the ground copper-sulfur mineral particles are placed in the screening frame 31. Next, the vibrating motor 34 is turned on, which drives the screening plate 33 to vibrate up and down, thereby causing the entire screening frame 31 to vibrate up and down. The copper-sulfur mineral particles are screened through the screening plate 33, and the screened copper-sulfur mineral particles slide down along the guide plate 36 into one of the flotation cells 11. After screening, the elastic block 32 is pressed inward and the screening plate 33 is rotated downward until the screening plate 33 contacts the top of the guide plate 36. During this process, the copper-sulfur mineral particles on the screening plate 33 slide down into the other flotation cell 11. In this way, the ground copper-sulfur mineral particles can be screened and fed to different flotation conditions, which can improve the recovery rate and reduce the amount of reagent used.

[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] Protective plates 4 are fixedly provided on both sides of the top of the screening plate 33, and the side of the protective plate 4 away from the vibrating motor 34 is semi-circular.

[0040] This prevents motion interference between the protective plate 4 and the screening frame 31 when the protective plate 4 rotates downwards along with the screening plate 33.

[0041] The length of the protective plate 4 is shorter than the width of the inner wall of the screening frame 31.

[0042] Working principle: When the screening plate 33 is opened and rotated downwards to feed the material, the copper-sulfur mineral particles on the screening plate 33 slide down along the screening plate 33 into another flotation cell 11. During the process of the copper-sulfur mineral particles sliding down the screening plate 33, the protective plate 4 prevents the copper-sulfur mineral particles from sliding out from one side of the screening plate 33. This can protect the copper-sulfur mineral particles during feeding and ensure that they slide into the flotation cell 11.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
