[0002] In the field of mineral processing technology, common techniques include gravity separation, magnetic separation, and flotation, including wind separation, which utilizes gas at a certain velocity to selectively separate target substances. For example, tail gas dust collection in common roasting plants is a form of wind separation, but it is limited to collecting dust and has no clear purpose, other than environmental protection. However, even dust has different values ​​depending on its particle size or form. For example, dust of a specific particle size may contain high concentrations of target substances of varying value. This necessitates equipment that can effectively separate these dust substances and efficiently collect these valuable substances. Utility Model Content

[0024] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0025] Example 1

[0026] like Figure 1-2 As shown, this embodiment is a mineral air separation device, including an air separation box 1 and an air pump 4. The air separation box 1 is connected to the air pump 4 to form a wind connection. A feed hopper 5 is provided at the upper part of the air separation box 1 near the air inlet. No less than three sample boxes 7 are arranged side by side along the wind direction at the bottom of the air separation box 1. Each sample box 7 is connected to a funnel 8 for receiving materials, and the height of the funnel 8 increases successively along the wind direction. An upwardly movable baffle 13 is provided in the air separation box 1, and a baffle handle 12 is connected to the upper part of the baffle 13. The number of baffles 13 is one less than the number of funnels 8, and the corresponding two funnels 8 can be separated by the baffle 13. An air outlet is provided on the side of the air separation box 1, and the number of the air outlets is consistent with the number of funnels 8, and the positions are also matched one by one with the positions of the funnels 8.

[0027] In a specific application, the baffles 13 are generally designed to be three pieces, and the corresponding funnels 8 and sample boxes 7 are four.

[0028] When performing air separation, first select the number of funnels 8 and sample boxes 7, and sort the funnels, baffles, and air outlets according to the wind direction. If two are needed, insert the second baffle 13, connect the dust bag to the second air outlet, and block the other air outlets.

[0029] Afterwards, start the air pump 4 to form an air separation airflow in the air separation box 1, and then feed from the feed hopper 5, and the mineral smoke dust falls into the air separation box from the feed hopper 5. Under the action of wind, large particles of smoke dust are blown into the first funnel 8 and then into the first sample box. Smaller smoke dust is blown by the wind and falls into the second funnel 8 and enters the second sample box. Even smaller smoke dust will be blown out from the air outlet and then collected by the dust bag, thus realizing three-stage air separation. According to different dust collection requirements, you can choose to lower different baffles or not to lower any baffles, and install the dust bag to the corresponding air outlet to realize the level selection of multi-stage air separation.

[0030] Further optimization of the above embodiment, such as Figure 5 As shown, the funnel 8 includes a funnel body 15 and a funnel connecting tube 16 for connecting the funnel body 15 and the sample box 7. The bottom funnel body 15 is a structure with an outer square and an inner cone. The interior of other funnel bodies 15 is conical, and the upper side surface of the outside is an inclined surface, and the lowest point is close to the air inlet direction. A funnel inclined block 17 is also provided at the lower end of the inclined surface of the funnel body 15. The funnel inclined block 17 is used to connect the lowest point of the inclined surface of this funnel body 15 with the highest point of the inclined surface of the adjacent funnel body 15.

[0031] In the design of this optimized structure, all the funnels are formed into approximately inclined surfaces, so that the smoke and dust blown over will fall into the corresponding funnel. Even if it initially falls on the funnel inclined block 17, it will slide into the corresponding funnel, thus ensuring a good and complete air separation and collection effect.

[0032] Example 2

[0033] like Figure 2 As shown, compared with Example 1, the feed hopper 5 of this embodiment has a larger opening, a flat rectangular lower end, and a partition fence 6 in the middle. The upper air inlet 2 and the lower air inlet 3 are provided on the side of the air separation box 1, and the upper air inlet 2 and the lower air inlet 3 are both connected to an air pump 4, the upper air inlet 2 blows air horizontally, and the lower air inlet 3 blows air obliquely upward.

[0034] Compared with Example 1, in this embodiment, after the smoke and dust material is poured into the feed hopper 5, the accumulated smoke and dust material can be scattered into the air separation box through the action of the partition fence 6, and the falling smoke and dust will pass through the horizontal wind of the upper air inlet 2 and the inclined wind of the lower air inlet 3 in turn. When the horizontal wind acts, some of the smoke and dust that are stuck together may be mistakenly selected into large particles. After the action of the inclined wind of the lower air inlet 3, further air separation can be achieved, thereby improving the effect of air separation, especially in the process of adding a large amount of smoke and dust, the horizontal wind at the upper air inlet 2 alone cannot completely air separate all the materials. With the action of the inclined wind of the lower air inlet 3, the unfinished materials at the upper air inlet can be air separated, which can improve the efficiency of air separation.

[0035] Example 3

[0036] like Figure 2-3 Compared with Example 1, the air outlet of this embodiment is equipped with an air outlet pipe 9, and a valve 10 for opening and closing the air outlet pipe 9 is installed on the air outlet pipe 9. The end of the air outlet pipe 9 is spaced apart with an air duct flange 11, and the dust collecting bag is tightly sleeved between the air duct flanges 11 through an elastic ring.

[0037] The air outlet pipe 9 of this embodiment can be opened and closed simply by twisting the valve 10, which is easy to operate. The dust bag can be pressed against the air outlet pipe 9 by the elastic ring, making it easy to install and remove the dust bag.

[0038] Example 4

[0039] like Figure 4 As shown, compared with embodiment 1, this embodiment further designs the baffle 13. A deformable sealing rubber sleeve 14 is glued to the lower part of the baffle 13, and the sealing rubber sleeve 14 can form a sealing effect with the edge of the funnel 8 and the extraction port of the baffle 13.

[0040] Compared with Example 1, this embodiment mainly optimizes the insertion and removal of the baffle 13. When the baffle 13 needs to be inserted for sealing, the baffle 13 is pressed down by the baffle handle 12, so that the lower part of the sealing rubber sleeve 14 is pressed on the edge of the funnel 8 and deformed, thereby achieving a sealing effect. When the baffle 13 is pulled upward, it is not necessary to pull it out completely. If it is pulled out completely, an air leak will be formed. The structural design of this embodiment is that during the process of pulling the baffle 13 upward, the groove on the top of the air separation box will squeeze the sealing rubber sleeve 14, causing the sealing rubber sleeve 14 to deform, and the friction force generated can overcome the gravity of the baffle 13, so that sealing can be achieved while ensuring that the baffle 13 will not fall without the action of external force.

[0041] It should be further clarified that, in the description of the present invention, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0042] Unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or removable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0043] Unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0044] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
