Description

Technical Field

[0001] This utility model belongs to the field of metal beneficiation technology, and in particular relates to a flotation column feeding and slag removal device. Background Technology

[0002] Static microbubble cyclone flotation columns are key equipment in fine-particle mineral processing due to their excellent classification effect, high production efficiency, and material and cost savings. Therefore, they are widely used in fine-particle mineral processing. Flotation columns with depths exceeding 7 meters and diameters ranging from 2.5 to 3.2 meters often contain a large amount of blast furnace casings and impurities. During circulation within the flotation column, these materials can easily clog the bubble generator, tailpipe, and slurry valve core, disrupting normal production. Utility Model Content

[0003] The purpose of this invention is to provide a flotation column feed and slag removal device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A flotation column feed and slag removal device includes a flotation column, which further includes a slag removal chamber, a screen plate, and a slag cleaning zone, wherein the slag cleaning zone is located on one side of the slag removal chamber;

[0006] The top of the slag removal chamber is connected to the feed pipe, and the bottom is provided with a discharge pipe connected to the flotation column. The sieve plate is provided inside, and the sieve plate is used to coarsely screen the material entering through the feed pipe. The side wall of the slag removal chamber is provided with a slag outlet corresponding to the sieve plate. The slag outlet is connected to the slag cleaning zone, and the slag cleaning zone is used to receive the debris flowing out of the slag outlet.

[0007] As a further improvement of this utility model, the screen plate penetrates the side wall of the slag removal chamber and is located on the slag cleaning zone.

[0008] As a further improvement of this utility model, the position of the sieve plate penetrating through the slag removal chamber is located at the upper part of the bottom of the slag outlet.

[0009] As a further improvement of this utility model, the sieve plate is perpendicular to the feeding direction of the feed pipe.

[0010] As a further improvement of this utility model, the slag removal zone includes a bottom plate and baffles disposed on both sides of the bottom plate. One end of the bottom plate is connected to the slag outlet, and the free end extends away from the slag removal chamber.

[0011] As a further improvement of this utility model, the base plate is inclined downward.

[0012] As a further improvement of this utility model, the thickness of the sieve plate is 10mm, and the diameter of the sieve holes on it is 5mm.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] This invention separates impurities from the slurry in the feed by adding a slag removal device, making the feed to the flotation column cleaner. This greatly reduces the occurrence of blockages in the bubble generator, tailpipe, and slurry valve core, ensuring stable operation of the flotation column and reducing maintenance intensity.

[0016] The markings in the diagram are as follows: 1. Slag removal chamber, 2. Screen plate, 3. Slag cleaning area, 4. Feed pipe, 5. Discharge pipe, 6. Slag outlet, 7. Bottom plate, 8. Baffle. Detailed Implementation

[0017] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0018] like Figure 1 The flotation column feeding and slag removal device shown includes a flotation column, which further includes a slag removal chamber 1, a screen plate 2, and a slag cleaning zone 3. The slag cleaning zone 3 is located on one side of the slag removal chamber 1. In this embodiment, the flotation column has a size of 3200×7000mm and the slag removal chamber 1 has a size of 700×600mm.

[0019] The top of the slag removal chamber 1 is connected to the feed pipe 4, and the bottom is provided with a discharge pipe 5 connected to the flotation column. The screen plate 2 is provided inside. The screen plate 2 is used to coarsely screen the material entering through the feed pipe 4, and the screen plate 2 is perpendicular to the feeding direction of the feed pipe 4.

[0020] The slag removal chamber 1 has a slag outlet 6 on its side wall, corresponding to the sieve plate 2. The slag outlet 6 is connected to the slag cleaning zone 3, which is used to collect the debris flowing out of the slag outlet 6. Furthermore, the sieve plate 2 penetrates the side wall of the slag removal chamber 1 and is located on the slag cleaning zone 3, with the position of the sieve plate 2 penetrating the slag removal chamber 1 above the bottom of the slag outlet 6. The sieve plate 2 has dimensions of 1500×600mm, a thickness of 10mm, and a sieve aperture of 5mm.

[0021] In this embodiment, the slag removal zone 3 includes a bottom plate 7 and baffles 8 disposed on both sides of the bottom plate 7. One end of the bottom plate 7 is connected to the slag outlet 6, and the free end extends away from the slag removal chamber 1. The screen plate 2 is located on the upper part of the bottom plate 7, and the baffles 8 are used to prevent debris on it from falling to the ground. Furthermore, the bottom plate 7 is inclined downwards, so that the debris on it is better cleaned under the action of gravity.

[0022] The working principle is as follows: Material flows through the feed pipe 4 into the slag removal chamber 1. Since the slag removal chamber 1 is equipped with a screen plate 2, debris such as blasting casings larger than the aperture is blocked at the top of the screen plate 2 and flows through the slag outlet 6 onto the screen plate 2 on the bottom plate 7, facilitating cleaning by personnel. Material smaller than the aperture flows out from the discharge pipe 5 and into the interior of the flotation column. By setting up this device, the material entering the flotation column is coarsely screened, making the feed to the flotation column cleaner, improving the cleanliness of the slurry, reducing the frequency of bubble generator clogging, improving the stability of the flotation column, and reducing maintenance intensity.

[0023] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
