Description

Technical Field

[0001] The invention relates to the technical field of mineral flotation, and in particular to a high-efficiency gas flotation machine. Background Art

[0002] After ore mining, different minerals need to be screened, and a flotation machine is needed. The main principle of the flotation machine is to use the difference in surface properties of minerals to bring out the minerals with poor hydrophilicity through the buoyancy of bubbles. The minerals with poor hydrophilicity then float to the upper surface of the slurry with the bubbles to form froth, and then the froth is sent to the froth box under the action of the defoaming device for the next process.

[0003] In the prior art, the bubble generating device of the flotation machine is mainly composed of an impeller and an air inlet channel. When the impeller rotates, negative pressure is generated at the impeller, and the air outside the flotation machine is sucked in through the air inlet pipe. The sucked air reacts with the reagent to generate bubbles. The bubble generating method of sucking air in through the rotation of the impeller causes a small amount of air to be introduced into the slurry, and the efficiency of bubble generation is low, resulting in low flotation efficiency. Summary of the invention

[0004] In view of the above problems, the present invention provides a high-efficiency gas flotation machine to solve the problem in the prior art that the bubble generation efficiency is low and thus the flotation efficiency is low.

[0005] The present invention is realized by using the following technical scheme: a high-efficiency gas flotation machine, comprising a flotation box, a froth box and a defoaming device are installed on the flotation box, a slurry pipe is also arranged at the bottom of the flotation box, a main pipe for conveying air is arranged in the flotation box, a plurality of first flow guide nozzles are fixedly connected and communicated with the main pipe, and the nozzles of the plurality of first flow guide nozzles are all oriented in the counterclockwise or clockwise direction; The main pipe is also connected to a first frame-shaped pipe, and a plurality of or a plurality of groups of second guide nozzles are fixedly connected to the first frame-shaped pipe. When the nozzle of the first guide nozzle faces clockwise, the nozzle of the second guide nozzle also faces clockwise. When the nozzle of the first guide nozzle faces counterclockwise, the nozzle of the second guide nozzle also faces counterclockwise. The first guide nozzle and the second guide nozzle are both located in the flotation box.

[0006] Through the above structure, the device can directly introduce a large amount of air into the slurry in the flotation box through the first guide nozzle and the second guide nozzle, thereby increasing the air content in the slurry during the flotation process, improving the efficiency of bubble generation during the flotation process, and thus improving the overall efficiency of the mineral flotation process.

[0007] Preferably, the first flow guide nozzle is in an "L" shape, and a plurality of first flow guide nozzles are arranged in a horizontal direction, and the first flow guide nozzles are distributed in a circumferential array on the main pipe. By arranging the first flow guide nozzles in an "L" shape and in a circumferential array, the device can make the slurry generate a rotating flow while introducing a large amount of air into the slurry, thereby replacing the impeller and accelerating the attachment of minerals with poor hydrophilicity to bubbles.

[0008] Preferably, the first frame-shaped tube is rectangular, and includes a first side tube and a third side tube that are parallel to each other, and a second side tube and a fourth side tube that are parallel to each other. Both ends of the first side tube and the third side tube are fixedly connected and communicated with the ends of the second side tube and the fourth side tube, and both ends of the second side tube and the fourth side tube are fixedly connected to the flotation box. The arrangement of the rectangular first frame-shaped tube makes it more convenient to install it on the flotation box, thereby increasing the stability of the device.

[0009] Preferably, the first frame tube is provided with four groups of second flow-guiding nozzles, which are respectively arranged at the end of the first side tube close to the second side tube, the end of the second side tube close to the third side tube, the end of the third side tube close to the fourth side tube, and the end of the fourth side tube close to the first side tube. The second flow-guiding nozzles are located inside the first frame tube and the nozzles are oriented perpendicular to the axis direction of the side tube on which they are installed. The arrangement of multiple groups of second flow-guiding nozzles further promotes the flow of slurry, allowing minerals with poor hydrophilicity to attach to bubbles more quickly, further improving the flotation efficiency of the device.

[0010] Preferably, the front and rear sides of the main pipe are fixedly connected and communicated with a second branch pipe, and the end of the second branch pipe away from the main pipe is fixedly connected and communicated with the middle of the second side pipe and the middle of the fourth side pipe. The arrangement of the second branch pipe ensures that air can flow through the first frame pipe normally.

[0011] Preferably, the first guide nozzle and the second guide nozzle are located in the same plane, and the first frame tube, the first guide nozzle, the second guide nozzle, and the second branch pipe form a group of guide pipes, and two groups of guide pipes are provided in the vertical direction. The two groups of guide pipes can increase the amount of air introduced into the slurry and improve the efficiency of bubble generation, and can also promote the slurry to generate a stable rotating flow, improve the attachment efficiency of minerals and bubbles, and thus improve the efficiency of mineral flotation.

[0012] Preferably, the main pipe is arranged in the vertical direction, the top of the main pipe is fixedly connected and communicated with the air inlet pipe, the bottom of the main pipe is communicated with the second frame pipe, and the bottom of the second frame pipe is fixedly connected and communicated with a plurality of dredging nozzles with nozzles facing downward. Through the arrangement of the second frame pipe and the dredging nozzles, the minerals deposited at the bottom of the flotation box can be blown up again and continue to return to the flotation process, making the flotation more complete and further improving the efficiency of the flotation.

[0013] Preferably, the second box-shaped pipe is rectangular. The bottom end of the main pipe is fixedly connected and communicated with a third branch pipe. Both ends of the third branch pipe are fixedly connected and communicated with the middle parts of the left and right sides of the second box-shaped pipe respectively. A plurality of dredging spray pipes are also arranged at the bottom of the third branch pipe. The third branch pipe and the second box-shaped pipe form a "day"-shaped pipeline. Through the arrangement of the rectangular second box-shaped pipe, the second rectangular pipe can better fit around the bottom of the flotation tank, thereby improving the utilization rate of the dredging spray pipes.

[0014] Preferably, the defoaming device includes first branch pipes fixedly connected and communicated with both the left and right sides of the main pipe. One end of the first branch pipe far from the main pipe is fixedly connected with the flotation tank. A plurality of "T"-shaped defoaming spray pipes are fixedly connected and communicated with the bottom of the first branch pipe. One defoaming spray pipe is provided with two nozzles. The two nozzles of the defoaming spray pipe face the front and back directions respectively. Through the arrangement of a plurality of defoaming spray pipes, the floating foam can be continuously blown towards the flotation tank, improving the defoaming efficiency of the defoaming device, thus better coping with the characteristic that the device can generate a large number of bubbles, avoiding the accumulation of floating foam, and further improving the flotation efficiency.

[0015] Preferably, there are two floating foam boxes, which are respectively fixedly installed on the front and back sides of the flotation tank. Through the arrangement of the two floating foam boxes, it can cope with the characteristic of two-way defoaming of the defoaming spray pipes.

[0016] In summary, the beneficial effects of the present invention are as follows: 1. Through the diversion pipeline composed of the first diversion spray pipe, the second diversion spray pipe, etc., the device can not only increase the amount of air introduced into the pulp in the flotation tank, improve the generation speed of bubbles, but also drive the pulp to flow in the direction of the jet of the first diversion spray pipe and the second diversion spray pipe, improving the attachment rate of minerals with poor hydrophilicity to bubbles, thereby improving the flotation efficiency of the pulp.

[0017] 2. Through the arrangement of the second box-shaped pipe and the dredging spray pipes, the phenomenon that part of the ore powder deposits downward due to the self-gravity of the minerals during long-term flotation of the pulp can be reduced, thereby further improving the flotation efficiency and making the flotation of the pulp more complete.

DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0022] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, the present invention provides a high-efficiency gas flotation machine, including a flotation box 1, a froth box 11 is fixedly installed on both the front and rear sides of the flotation box 1, and a slurry pipe 12 for introducing slurry is provided at the bottom of the flotation box 1, wherein the froth box 11, the slurry pipe 12, the flotation box 1, etc. are all conventional prior arts in the field, and their structures can be easily obtained by searching patents, videos, etc. in the field, so no further details are given here. An air intake pipe 2 arranged horizontally in the left and right directions is fixedly installed above the flotation box 1, and the air intake pipe 2 can be connected to an air suspension blower and other devices for conveying high-pressure air. A flotation pipeline 3 connected to the air intake pipe 2 is fixedly installed in the flotation box 1. Among them, the flotation pipeline 3 includes a defoaming pipeline 4 arranged at the top of the flotation box 1, a diversion pipeline 5 arranged in the middle of the flotation box 1, and a silt removal pipeline 6 arranged at the bottom of the flotation box 1.

[0024] like Figure 1 , Figure 3 , Figure 4As shown, the bottom of the air inlet pipe 2 is fixedly connected and communicated with a main pipe 21 arranged in the vertical direction, and the main pipe 21 is located in the middle of the flotation box 1. A defoaming device is provided on the top of the flotation box 1, and the defoaming device is a defoaming pipeline 4. The defoaming pipeline 4 includes two first branch pipes 41 arranged horizontally in the left and right directions. The end of the first branch pipe 41 close to the main pipe 21 is fixedly connected and communicated with the left and right sides of the main pipe 21 respectively, and the end of the first branch pipe 41 away from the main pipe 21 is fixedly connected to the flotation box 1. The bottom of the first branch pipe 41 is fixedly connected and communicated with a plurality of "T"-shaped defoaming nozzles 42. The defoaming nozzle 42 is provided with two nozzles, and the two nozzles face the front and rear directions respectively. The defoaming nozzles 42 are equidistantly arranged along the axis direction of the first branch pipe 41.

[0025] The existing defoaming device is mainly driven by a motor to rotate a rotating shaft, and a plurality of scrapers are fixedly installed on the rotating shaft. The rotation of the rotating shaft drives the scrapers to rotate, thereby scraping the foam into the foam box 11. In the process of driving the foam forward, the scrapers will also push the top layer of slurry to move toward the foam box 11. Since the scrapers scrape the foam intermittently, when the first scraper is separated from the slurry, the slurry pushed forward will flow back, that is, flow in the direction away from the foam box 11, and most of the foam on the upper surface of this part of the slurry will be scraped off. The reflux of the slurry will also reduce the amount of foam floating forward, resulting in less foam pushed by the second scraper when it reaches the slurry, and the defoaming efficiency is low. When the scraper-type defoaming device is applied to the froth box 11, its defoaming efficiency is low, while the efficiency of generating froth is high, which leads to the accumulation of froth and affects the efficiency of flotation. The defoaming pipeline 4 for continuously blowing the froth provided in this embodiment can improve this problem. By continuously blowing the froth to the front and rear sides, the deposition of froth on the surface of the slurry is reduced, thereby increasing the efficiency of flotation.

[0026] like Figure 1 , Figure 3 , Figure 5 As shown, the main pipe 21 is also fixedly connected and connected with a plurality of horizontally arranged first flow guide nozzles 52, and the nozzles of the plurality of first flow guide nozzles 52 are all facing counterclockwise or clockwise. The main pipe 21 is also connected with a horizontally arranged first frame pipe, and the first frame pipe is fixedly connected with a plurality or a plurality of groups of horizontally arranged second flow guide nozzles 57, and the nozzles of the plurality or a plurality of groups of second flow guide nozzles 57 are also facing clockwise or counterclockwise; specifically, when the nozzle of the first flow guide nozzle 52 is facing clockwise, the nozzle of the second flow guide nozzle 57 is also facing clockwise, and when the nozzle of the first flow guide nozzle 52 is facing counterclockwise, the nozzle of the second flow guide nozzle 57 is also facing counterclockwise. The first flow guide nozzle 52 and the second flow guide nozzle 57 are both located in the flotation box 1.

[0027] Specifically, the first flow guide nozzle 52 is in an "L" shape, and a plurality of first flow guide nozzles 52 are arranged in the horizontal direction, and the first flow guide nozzles 52 are distributed in a circular array on the main pipe 21. The first frame pipe is rectangular, and includes a first side pipe 51 and a third side pipe 54 that are parallel to each other, and a second side pipe 53 and a fourth side pipe 55 that are parallel to each other. Both ends of the first side pipe 51 and the third side pipe 54 are fixedly connected and communicated with the ends of the second side pipe 53 and the fourth side pipe 55, and both ends of the second side pipe 53 and the fourth side pipe 55 are fixedly connected to the flotation box 1.

[0028] Four groups of second flow guide nozzles 57 are provided on the first frame tube. The four groups of second flow guide nozzles 57 are respectively arranged at the end of the first side tube 51 close to the second side tube 53, the end of the second side tube 53 close to the third side tube 54, the end of the third side tube 54 close to the fourth side tube 55, and the end of the fourth side tube 55 close to the first side tube 51. The second flow guide nozzles 57 are located on the inner side of the first frame tube and the nozzle directions are perpendicular to the axial direction of the side tube on which they are installed.

[0029] The front and rear sides of the main pipe 21 are fixedly connected and communicated with the second branch pipe 56, and the end of the second branch pipe 56 away from the main pipe 21 is fixedly connected and communicated with the middle of the second side pipe 53 and the middle of the fourth side pipe 55. The flow guide pipeline 5 is composed of the first flow guide nozzle 52, the first frame pipe, the second flow guide nozzle 57 and the second branch pipe 56; specifically, the first flow guide nozzle 52 and the second flow guide nozzle 57 are located in the same plane.

[0030] By setting the guide pipe 5, it can replace the driving impeller. Under the action of the first guide nozzle 52 and the second guide nozzle 57, the amount of air introduced into the slurry is greatly increased. At the same time, the slurry can also flow under the action of high-pressure air, thereby accelerating the attachment of minerals and bubbles, thereby increasing the flotation efficiency.

[0031] In order to further increase the amount of air introduced into the slurry during flotation and promote the slurry to flow in the direction of the nozzles of the first guide nozzle 52 and the second guide nozzle 57, in the present embodiment, two groups of guide pipes 5 are provided, and the two groups of guide pipes 5 are arranged at intervals in the up and down directions. The structures of the upper and lower groups of guide pipes 5 are roughly the same. The difference is that the second branch pipe 56 of the upper guide pipe 5 is located above the second guide nozzle 57, and the second branch pipe 56 of the lower guide pipe 5 is located below the second guide nozzle 57. This arrangement is mainly to prevent the second branch pipe 56 from affecting the first guide nozzle 52 and the second guide nozzle 57 to spray according to the trajectory.

[0032] like Figures 1 to 3 , Figure 6As shown, the desilting pipeline 6 is located below the diversion pipeline 5, and the desilting pipeline 6 includes a third branch pipe 62 arranged horizontally in the left-right direction, the bottom end of the main pipe 21 is fixedly connected and communicated with the middle of the third branch pipe 62, and the two ends of the third branch pipe 62 are fixedly connected and communicated with the left and right sides of the second frame-shaped pipe 61, and a plurality of vertically arranged desilting nozzles 63 with nozzles facing downward are fixedly connected and communicated at the bottom of the third branch pipe 62 and the second frame-shaped pipe 61. Among them, the second frame-shaped pipe 61 is rectangular, and the second frame-shaped pipe 61 and the third branch pipe 62 form a "sun"-shaped pipeline.

[0033] If there is no desilting pipeline 6, part of the mineral powder will fall down under the action of its own gravity after long-term flotation of the slurry, and the mineral powder falling down will be deposited around the bottom of the flotation box 1 under the flow of the slurry, thereby reducing the flotation efficiency. By adding a desilting pipeline 6, after the mineral powder falls to the bottom of the flotation box 1, it will be blown up again by the desilting nozzle 63, so that the deposited mineral powder is mixed with the slurry again, so that the flotation of the slurry is more comprehensive and the flotation efficiency is higher.

[0034] The operating principle of the device is as follows: first, the ore pulp is introduced into the flotation box 1, and then high-pressure air is introduced into the air inlet pipe 2 through equipment such as an air suspension blower. The high-pressure air will be ejected from the first guide nozzle 52, the second guide nozzle 57 and the desilting nozzle 63, thereby introducing a large amount of air into the ore pulp, so that more and faster bubbles are generated. The first guide nozzle 52 and the second guide nozzle 57 can drive the ore pulp to flow, thereby accelerating the attachment of minerals and bubbles. The air blown out of the desilting nozzle 63 can also blow up the mineral powder at the bottom of the flotation box 1, thereby accelerating the efficiency of flotation. Minerals with poor hydrophilicity will float upward with the bubbles after attaching to the bubbles, thereby forming froth on the surface of the ore pulp. The high-pressure air delivered by the air inlet pipe 2 will also be ejected from the defoaming nozzle 42, and the defoaming nozzle 42 will blow the froth floating on the surface of the ore pulp to the front and rear directions until the froth falls into the froth box 11.

[0035] In summary, the present invention provides a high-efficiency gas flotation machine. The guide pipe 5 formed by the first guide nozzle 52, the second guide nozzle 57, etc. enables the device to increase the amount of air introduced into the slurry in the flotation box 1 and improve the bubble generation rate, and can also drive the slurry to flow in the direction of the first guide nozzle 52 and the second guide nozzle 57, thereby increasing the rate of attachment of minerals with poor hydrophilicity to bubbles, thereby improving the efficiency of slurry flotation; through the arrangement of the second frame tube 61 and the dredging nozzle 63, the phenomenon of partial mineral powder being deposited downward due to the gravity of the mineral itself under long-term flotation of the slurry can be reduced, thereby further improving the flotation efficiency and making the flotation of the slurry more complete.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
