The invention relates to the technical field of flotation machines, in particular to a forced recovery device for flotation foam.
Background
The foam flotation is a modern main flotation method and is mainly characterized in that materials with different wettability by water are separated by utilizing a gas-liquid interface of bubbles. The hydrophobic materials float to the water surface along with the air bubbles to form a foam layer with high content of certain components; whereas the material, which is wetted by water, sinks in the water, thus separating the useful minerals from the gangue minerals. In order to realize the purpose of ' collecting and collecting in advance ', collecting and collecting in advance ' of mineral resources in the flotation process and timely sending the mineral resources to the next stage for treatment, the foam products need to be recovered quickly and efficiently. The equipment for realizing the foam flotation comprises a flotation machine and a flotation column, and the foam collection mode is usually scraper collection or auxiliary foam self-flowing through adding structural members such as a foam pushing cone, an inner foam groove, an outer foam groove and a radial foam groove, so that the quick and efficient recovery of foam products is ensured.
Patent CN202316123U, discloses "a froth scraping mechanism of flotation machine", the shortcoming of this mechanical structure scraper lies in: (1) the scraper is fixed in spatial position and cannot adapt to the instability of the mineral processing process flow, namely, when the flow is unstable, the foam product cannot be timely and efficiently recovered; (2) the ore properties are different, the medicament system is different, the stability of foam is different, defoaming after the foam product is collected has different degrees of difficulty, and the treatment in the next stage is not facilitated; (3) the area covered by the scraper is limited, and the foam stays for a long time in the uncovered area, which is not beneficial to the efficient recovery of the foam product.

The circular groove structure is not beneficial to the quick and efficient recovery of the foam product, and the retention time of the foam product is prolonged. Meanwhile, according to different mineral properties and medicament systems, foam products have a defoaming problem to a certain extent, and additional foam washing water is also needed to be added to increase the water consumption; the foam gravity flow has a great requirement on the levelness of the installation of the overflow weir, the situation that the installation of the overflow weir is not horizontal often occurs on site, and then the phenomenon that the foam is generated while the foam is generated in the flotation machine is avoided, and the load capacity of the overflow weir is increased through phase change. When the foam flows automatically, the height of the overflow weir is generally fixed, so that the overflow weir cannot adapt to the instability of the mineral separation process, namely, when the mineral feeding amount, the chemical system and the air charging amount are unstable, the foam cannot be discharged in time, and the flotation effect is deteriorated.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the invention provides a forced recovery device for flotation froth, which comprises a flotation machine body 1, a froth collection cabin 2, a froth suction cup 3 and a vacuum pump 4, wherein the froth collection cabin 2 is positioned at one side of the flotation machine body 1, the froth suction cup 3 is positioned above the liquid level of the flotation machine body 1, the froth suction cup 3 and the vacuum pump 4 are both connected with the froth collection cabin 2, and the bottom of the froth collection cabin 2 is connected with a discharging device 5.
The flotation machine body 1 is a flotation cabin without a scraper, one side of the foam collecting cabin 2 is connected with a vacuum pump 4, the foam collecting cabin 2 is in a negative pressure state due to the action of the vacuum pump 4, the foam sucker 3 which is also connected with the foam collecting cabin 2 draws air inwards, because the foam sucker 3 is positioned above the liquid level of the flotation machine body 1, when the foam drives the material to float to the upper layer of the liquid level, the foam layer above the liquid surface is sucked in by the foam suction cups 3 through the first duct 6 into the interior of the foam collecting chamber 2, where it is to be understood that the foam suction cups 3 suck in the foam layer above the liquid surface, only the foam product is sucked in, the suction can be carried out above the foam layer, but the distance between the bottom of the foam suction cup 3 and the foam layer is proper, the suction cannot be successfully carried out when the distance is too far, and the suction can be carried out when the distance is too close; the foam is at the in-process that gets into foam collection cabin 2, or gets into behind the foam collection cabin 2, takes place the defoaming, and the gathering is in the foam collection cabin 2, and the foam product after the defoaming gets into discharge apparatus 5 through the action of gravity, gets into next manufacturing procedure behind discharge apparatus 5.
As shown in fig. 2, the foam suction cup 3 includes a bottom suction cup 301, the bottom suction cup 301 has a downward opening, a connection pipe 302 is connected to the top end of the bottom suction cup 301, the bottom suction cup 301 is located above the flotation machine body 1, a feeding port 201 is provided on the bulkhead of the foam collecting chamber 2, and the connection pipe 302 is connected to the feeding port 201 through a first pipe 6. I.e. similar to a funnel-shaped suction cup, the opening of the bottom suction cup 301 is downwards for sucking material from the liquid surface of the flotation machine body 1 and then through the connecting pipe 302 and the first pipe 6 into the froth collection chamber 2.
As shown in fig. 4, the number of the foam suction cups 3 is not less than two, the foam suction cups 3 are uniformly arranged along the liquid level of the flotation machine body 1, and the shape of the foam suction cups 3 is in a bell mouth shape or a flat mouth shape. It will be appreciated that, since the liquid surface of the flotation machine body 1 is generally of a certain area, if there is only one suction cup, on the one hand it may not be possible to fully draw in the froth product over the entire liquid surface, and on the other hand, even if the whole liquid level can be extracted through the liquidity of the liquid level, the flotation effect is reduced due to the uneven extraction of the foam products at the same liquid level, therefore, the number of the foam suction cups 3 is more than one, and the foam suction cups are uniformly arranged according to the outline of the liquid surface of the flotation machine body 1, so that the foam flowing distance of each suction point is uniform, in addition, when the flotation process is divided into different processes of rough concentration and fine concentration, the flotation process can be realized by designing different angles of the foam suction cups 3, for example, the opening angle of the foam suction cup 3 is made large (for example, more than 60 °) in the rough selection, and the opening angle of the foam suction cup 3 is made small (for example, less than 60 °) in the fine selection.
As shown in fig. 3, the foam collecting chamber 2 is a sealed barrel-shaped structure with a conical bottom, a vacuum pump port 202 is arranged on the wall of the foam collecting chamber 2, a protective mesh enclosure 14 is arranged in the vacuum pump port 202, the vacuum pump 4 is connected with the vacuum pump port 202 through a second pipeline 7, and the vacuum pump port 202 is not lower than the horizontal height of the feeding port 201.
The specific structure and the working mode of the vacuum pump 4 are not described again, the second pipeline 7 and the first pipeline 6 are both flexible pipelines, which are beneficial to the flow and the passing of liquid and gas, the protective mesh enclosure 14 is positioned inside the vacuum pump interface 202 or at the position of the vacuum pump interface 202 arranged on the inner wall of the foam collecting cabin 2, the protective mesh enclosure 14 is used for preventing the material in the foam collecting cabin 2 from being sucked by the vacuum pump 4, for example, a double-layer steel ring is welded inside the vacuum pump interface 202, and filter layers such as sponge are filled inside the double-layer steel ring, the structure capable of realizing the protective effect is diversified, which is not described again here, the bottom of the foam collecting cabin 2 is a conical bottom, which is beneficial to the foam product and the material flow down, and can not be accumulated, so that the height of the vacuum pump interface 202 is generally higher than that of the feed port 201, and the material entering, causing it to block the vacuum pump port 202 and cause the negative pressure to fail, and for the same reasons as described above, it is preferable to locate the vacuum pump port 202 and the feed port 201 on opposite sides of the foam collecting chamber 2 even if they are horizontally farthest apart.
The foam suction cup 3 is connected with a moving actuator 8, and the moving actuator 8 is used for controlling the position of the foam suction cup 3. The moving actuator 8, i.e. the moving mechanism of the foam sucker 3, may be specifically a horizontal moving mechanism in XY direction, a vertical moving mechanism in Z direction, or a three-dimensional moving mechanism in XYZ direction, and the specific choice needs to be determined according to the effective suction range of the foam sucker 3, for example, when the foam sucker 3 only effectively sucks a partial area, the horizontal moving mechanism is required to control the foam sucker 3 to continuously move horizontally to suck the liquid surface foam, and when different foam products need to be collected only according to the distance between the foam sucker 3 and the liquid surface, only the vertical moving mechanism in Z direction is required, so the "controlling the position of the foam sucker 3" herein should be understood to be controlling the relative position between the foam sucker 3 and the liquid surface of the flotation machine body 1, such as the horizontal position and the height position, and such a moving actuator 8 should be very common, such as the moving mode of the crane, etc., and detailed description thereof is not necessary here.
A first liquid level detector 9 is arranged above the flotation machine body 1, and the first liquid level detector 9 and the mobile executing mechanism 8 are both connected with a first control system 10.

The inside of foam collecting chamber 2 is provided with second liquid level detector 11, and second liquid level detector 11 and vacuum pump 4 all are connected with second control system 12. The second liquid level detector 11 is used for detecting the liquid level of the foam product in the foam collecting chamber 2 in real time, when the liquid level is higher than a certain value, a signal is fed back to the second control system 12, the second control system 12 controls the vacuum pump 4 to stop working, it should be understood that the second control system 12 and the first control system 10 can be integrated into a total control system without separate control, only one control device, such as a PLC control cabinet, is needed, and only one operator is needed, so that the movement of the foam suction cup 3 and the start and stop of the vacuum pump 4 can be controlled simultaneously, the liquid level detector is mature prior art, and various channels are easily purchased, for example, a capacitive contact type liquid level detection sensor with the model WKC1204, and the structure and the working principle thereof are not repeated here.

That is, the connecting pipe 302 is connected to the first pipe 6 through the three-port connector 13, and is a passage connection for the passage of the foam product, while the connecting pipe 302 is connected to the connecting shaft of the movable actuator 8 through the three-port connector 13, and is a closed connection, and only plays a role of connection, in other words, it is needless to say that the three-port connector 13 is not used, so that the connecting pipe 302 is connected to the first pipe 6 through an intermediate pipeline, and the connecting pipe 302 is fixedly connected to the movable actuator 8 through some means, such as heat melting, welding, bolt connection, and the like.
