Description

Technical Field

[0001] The invention relates to the technical field of copper ore processing, and in particular to a copper ore quality improvement and impurity reduction processing system. Background Art

[0002] Flotation machines are generally used in copper ore quality improvement and impurity reduction systems. Flotation machines are used to perform rough processing on copper ore and are processed by flotation. Flotation is a technical method for separating useful minerals from ores based on the different physical and chemical properties of the mineral particle surfaces. Flotation is usually completed in a flotation machine. Reagents are added to the flotation machine to react with the slurry. Through stirring and aeration, some of the mineral particles are selectively fixed on the bubbles and float to the surface of the slurry, while the rest remain in the slurry to achieve the purpose of separating minerals. During the flotation process, minerals with weak adhesion will gradually break away from the bubbles and sink to form tailings, while useful metal minerals with greater adhesion will rise with the bubbles. A large number of bubbles carry metal minerals to form a foam layer and float to the surface of the slurry to be scraped out and finally form concentrate.

[0003] A Chinese patent discloses a pulp rapid flotation machine, and the patent application number is CN201510493442.9. A pulp rapid flotation machine, the motor device is connected to the central tube through a rotating shaft, the cover plate is fixedly connected to the bottom of the central tube, the impeller is fixedly connected to the cover plate, the lower end of the impeller is connected to a bearing, the bearing is rotatably connected to a high-pressure plunger pump, the right side of the high-pressure plunger pump is connected to a pulp pipe, the bubble scraping device is installed on the upper part of both sides of the flotation machine body, the flow stabilizing plate is arranged on both sides of the inside of the flotation machine body, and the flow stabilizing plate is close to the upper end of the flotation machine body, and the baffle is arranged at the bottom of the flotation machine body.

[0004] The above-mentioned comparative patent adopts double-sided scraping of the flotation machine to quickly process the foam produced by the flotation machine, but the scraping plate on the flotation machine cannot be adjusted. When the liquid level in the flotation machine is too high, the scraping plate is easy to scrape out the liquid in the flotation machine, causing the extraction purity of the copper ore to be greatly reduced. When the liquid level inside the flotation machine is too low, the foam generated is difficult to be scraped out by the scraping plate. In addition, foam is likely to remain on the surface of the scraping plate after each scraping. The water in the foam evaporates and finally remains on the scraping plate. Over time, the weight of the scraping plate will increase, resulting in a larger operating load on the motor driving the scraping plate. The large motor operating load is likely to reduce the service life of the motor.

[0005] Therefore, a copper ore quality improvement and impurity reduction processing system is proposed. Summary of the invention

[0006] The object of the present invention is to provide a copper ore quality improvement and impurity reduction processing system to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a copper ore quality improvement and impurity reduction processing system, comprising a body, a bubble storage tank is provided on one side of the upper end of the body, two groups of support rods are fixedly installed on the outer surface of the upper end of the body near the bubble storage tank, a first motor is fixedly installed on the outer surface of one side of the upper end of one group of support rods, a rotating shaft is fixedly installed on the output shaft end of the first motor, one end of the rotating shaft passes through the support rods and extends to the outer surface of the other group of support rods and is rotatably connected to the other group of support rods, three groups of fixed plates are evenly fixedly installed on the outer circular surface of the rotating shaft, a bubble scraping plate is slidably connected to the outer surface of one side of the fixed plates at both ends, a sliding rod is fixedly installed at the center position of the outer surface of one side of the bubble scraping plate, and the sliding rod is connected to the center The cam is secured to the upper and lower ends of the cams and is engageable with the cams of the control cabinet, the upper and lower ends of the cams are engaged with the cams and are engageable with the cams of the control cabinet.

[0008] In view of the problem that the scraper plate on the flotation machine cannot be adjusted, when the liquid level in the flotation machine is too high, the scraper plate is easy to scrape out the liquid in the flotation machine, causing the extraction purity of the copper ore to be greatly reduced. When the liquid level inside the flotation machine is too low, the foam generated is difficult to be scraped out by the scraper plate. When the scraper plate needs to be adjusted, the operator pinches the two pressing blocks to compress the first spring and the two pressing blocks slide toward each other at the same time. The sliding of the pressing blocks drives the clamping block at the lower end to separate from the clamping rack. Because the clamping rack is connected to the slide bar, when the clamping block is no longer engaged with the clamping rack, the slide bar is no longer fixed. At this time, the operator slides one of the scraper plates, and the sliding of the scraper plate drives the slide bar to be fixed. The plate slides, because one side of the slide rod is connected to a rack, sliding the slide rod will drive the gear meshing with the rack to rotate, and the other side of the gear is meshingly connected to another set of racks, so the rotation of the gear drives the other set of racks to slide in the opposite direction, because the other set of racks is connected to the other set of slide rods, and the other set of slide rods is connected to the other set of scraper plates, so when the gear drives the other set of racks to slide in the opposite direction, it will also drive the other set of slide rods and scraper plates to slide in the opposite direction, so that when one of the scraper plates is slid, the other set of scraper plates will be driven to move in the opposite direction, and when sliding to the appropriate position, the operator no longer pinches the two sets of pressing blocks, because the rebound force of the first spring will push the two sets of pressing blocks The pressing block slides backwards, and at the same time drives the block at the lower end of the pressing block to engage with the card rack, so that it brakes the sliding rod and the foam scraper plate is also fixed and cannot move. Then the first motor is started, and the rotation of the first motor drives the rotating shaft at the output shaft end to rotate, and also drives the fixed plate and the foam scraper plate fixed on the rotating shaft to rotate together, so that the foam scraper plate can well scrape the foam floating on the surface of the slurry into the foam storage tank, and the open end of the foam storage tank is connected to the next process so that it can be processed in a flow-line manner. The present invention realizes the adjustment of the foam scraper plate. When the copper ore slurry level is too low, the foam on the surface can be well scraped out, which improves the foam scraping efficiency. The foam scraper plate can be adjusted according to the height of the slurry level, which increases the present invention. The utility model discloses that compared with the existing method that the bubble scraping plate and the fixing plate slide through the slide groove and then are fixed by bolts, the present invention drives the other group of bubble scraping plates to slide by sliding any one of the bubble scraping plates. Compared with the existing method of adjusting one group of bubble scraping plates and then adjusting the other group of bubble scraping plates, the adjustment of the bubble scraping plates of the present invention is more convenient. The adjustment of the prior art cannot ensure that the adjusted sizes of the two are consistent. The present method utilizes the linkage of the two bubble scraping plates to achieve the consistent adjusted sizes of the two groups of bubble scraping plates. In addition, the present invention can fix the bubble scraping plates without pressing the pressing block after adjusting the bubble scraping plates. The operation is simple and quick. The prior art also needs to use tools to fix the bolts, which is troublesome and impractical.

[0009] Preferably, arch plates are fixedly connected to both sides of the outer surface of the upper end of the bubble storage tank, a scraper is rotatably connected to the outer surface of one side of a group of arch plates near the center position, and one end of the scraper is rotatably connected to the outer surface of another group of arch plates.

[0010] During the scraping process, the surface of the scraping plate will be formed by the bursting of foam and the refined copper slurry will adhere to the surface of the scraping plate. If the attached refined copper slurry is not cleaned in time, the weight of the scraping plate will increase as the amount accumulates, which increases the load of the first motor and reduces the service life of the first motor. In order to clean up the refined copper slurry attached to the surface of the scraping plate in time, a scraper is rotatably connected between the two sets of arched plates. After the scraper scrapers the foam into the foam storage tank, it continues to rotate upward. At this time, the surface of the scraper scraping foam will contact the scraper and drive the scraper to rotate upward. The scraper rotates to a certain position with the scraper. Because the bubble scraper plate no longer applies an upward rotational force to the scraper plate, the scraper plate will stop at a position and stick to the surface of the bubble scraper plate. As the bubble scraper plate rotates, its surface is cleaned. When the bubble scraper plate rotates to the point where it is no longer in contact with the scraper plate, the scraper plate automatically rotates downward and finally becomes a vertical state, which is convenient for the refined copper ore slurry to slide downward from the surface of the scraper plate and finally drip into the bubble storage tank. The present invention ensures that the scraper plate can be cleaned every time the bubble scraper plate rotates to the scraper plate, thereby avoiding the problem of excessive weight of the refined copper ore slurry attached to the surface of the scraper plate causing the first motor to be overloaded, thereby increasing the service life of the first motor.

[0011] Preferably, a lead block is fixedly connected to the interior of the scraper near the lower end.

[0012] In order to further improve the cleaning effect of the scraper on the surface of the scraper plate, a lead block is installed inside the scraper so that when the scraper contacts the scraper plate, the weight of the scraper fits more closely to the surface of the scraper plate, and the effect of removing the refined copper ore slurry on the surface of the scraper plate is more significant.

[0013] Preferably, a feed shell is fixedly connected to one side of the upper outer surface of the body, a first feed port is fixedly connected to the center position of the upper outer surface of the feed shell, a grinding roller is fixedly installed inside the feed shell below the first feed port, a discharge port is provided on one side above the grinding roller, a filter screen is provided inside the feed shell below the grinding roller, a return port is provided inside the feed shell on one side of the filter screen, a second motor is fixedly installed inside the feed shell below one side of the return port, a screw rod is fixedly connected to the output shaft end of the second motor, and a disc is fixedly connected to the lower end of the screw rod.

[0014] The copper ore raw materials are added to the flotation machine to react with the reagents. However, the quality improvement and impurity reduction treatment efficiency is low because some particles in the copper ore raw materials are too large and the reaction time with the reagents is too long. In order to improve the reaction efficiency, a grinding drum is installed below the first feed port, so that the copper ore raw materials passing through the grinding drum are ground once to make the particles of the copper ore raw materials smaller, so that the subsequent reaction with the reagents is faster and more complete. The copper ore raw materials passing through the grinding drum will finally fall to the filter below. The fully ground copper ore raw materials will pass through the filter and enter the flotation machine, and the copper ore raw materials that are not fully ground will flow through the filter. The slope of the filter screen enters the return port and falls on the outer surface of the disc. The rotation of the second motor drives the spiral rod to rotate, so that the coarse-grained copper ore raw materials on the surface of the disc are brought to the discharge port by the spiral rod. The coarse-grained copper ore raw materials enter the grinding drum again through the discharge port and are ground again, so that the copper ore particles become smaller to improve the subsequent processing efficiency. The present invention realizes multiple grinding of large-grained copper ore raw materials, making the grinding more sufficient, thereby improving the reaction rate of the subsequent copper ore raw materials and the reagent, and also improves the output rate of copper ore bubbles of the flotation machine, so that the efficiency of the bubble scraping plate for scraping bubbles is also greatly improved.

[0015] Preferably, a plurality of barrier strips are evenly fixedly connected to the outer surface of the upper end of the filter screen, a disassembly mechanism is fixedly connected to the center position of the outer surface of the other side of the filter screen, one end of the disassembly mechanism is fixedly connected to an electric telescopic rod, and the electric telescopic rod is fixedly connected to the feed shell.

[0016] In order to prevent the filter from being blocked during the filtration process and to ensure more complete filtration, the present invention pushes the filter back and forth by an electric telescopic rod to achieve better screening, while also avoiding the problem of large particles of copper ore raw materials blocking the filter opening. In addition, the barrier strips on the filter delay the copper ore raw materials on the filter from entering the return material opening along the slope of the filter, so that the electric telescopic rod pushes the filter back and forth to achieve more complete screening.

[0017] Preferably, the disassembly mechanism includes a second spring, a barrier ring, a cavity, an L-shaped slide rod, a slot, and a connecting rod; a connecting rod is fixedly installed at the middle position of the outer surface of one side of the filter screen, a slot is opened inside one end of the connecting rod, the lower end of the slot is an open end, an L-shaped slide rod is snap-connected inside the slot, the L-shaped slide rod is slidably connected to the electric telescopic rod, a cavity is opened inside one end of the electric telescopic rod, a barrier ring is fixedly connected to the outer surface of the L-shaped slide rod near the upper end, and a second spring is sleeved on the outer surface of the L-shaped slide rod near the barrier ring.

[0018] After the filter has been used for a period of time, the filtration effect may be affected due to aging of the material or changes in the mesh port during use of the filter, which may require replacement. The L-shaped slide bar is pressed to slide downward, and at the same time, one end of the L-shaped slide bar is separated from the slot, so that the filter connected to the connecting rod can be removed together, and the filter can be replaced. When the L-shaped slide bar is pressed, the barrier ring is driven downward to compress the second spring, and the cavity provides movement space for the second spring and the barrier ring. The present invention realizes rapid disassembly of the filter and improves the replacement efficiency of the filter.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention can effectively scrape out the foam on the surface when the copper ore slurry level is too low or too high by adjusting the scraper plate. The scraper plate can be adjusted according to the different levels of the slurry level, which increases the practicality of the present invention. In addition, the scraper plate is constantly cleaned during the process of scraping foam, thereby avoiding the accumulation of slurry on the surface of the scraper plate, which causes the weight of the scraper plate to become heavier and increases the load of the running motor.

[0021] 2. In the present invention, the large-particle copper ore raw materials screened by the filter net enter the grinding drum again for re-grinding, thereby achieving multiple grinding of the large-particle copper ore raw materials, making the grinding more sufficient and thus improving the reaction efficiency of the subsequent copper ore raw materials and the reagents. In addition, the electric telescopic rod pushes the filter net back and forth to improve the screening efficiency of the filter net. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figures 1 to 12 The present invention provides a technical solution for a copper ore quality improvement and impurity reduction treatment system:

[0040] A copper ore quality improvement and impurity reduction processing system, such as Figures 1 to 8 As shown, it includes a body 1, a bubble storage tank 9 is opened on one side of the upper end of the body 1, two groups of support rods 6 are fixedly installed on the position of the upper end outer surface of the body 1 near the bubble storage tank 9, a first motor 4 is fixedly installed on the outer surface of one side of the upper end of one group of the support rods 6, a rotating shaft 11 is fixedly installed on the output shaft end of the first motor 4, one end of the rotating shaft 11 passes through the support rods 6 and extends to the outer surface of another group of support rods 6 and is rotatably connected with the other group of support rods 6, three groups of fixed plates 10 are evenly fixedly installed on the outer circular surface of the rotating shaft 11, and a bubble scraping plate 5 is slidably connected to the outer surface of one side of the fixed plates 10 at both ends, and a sliding rod 29 is fixedly installed at the center position of the outer surface of one side of the bubble scraping plate 5, and the sliding rod 29 is slidably connected to the middle group of fixed plates 10, and the outer surface of the upper end of the sliding rod 29 A rack 15 is fixedly installed on the surface, a rack 14 is fixedly installed on the outer surface of one side of the lower end of the sliding rod 29, a fixed block 12 is fixedly installed at the center position of the outer surface of the upper end of the middle group of fixed plates 10, and pressing blocks 13 are slidably connected on both sides of the interior of the fixed block 12, one end of the pressing block 13 penetrates the fixed block 12 and extends to the outside, a first spring 18 is fixedly connected to the center position of the outer surface of one side of a group of pressing blocks 13, and the other end of the first spring 18 is fixedly connected to another group of pressing blocks 13, and a block 17 is fixedly connected to the lower end of the pressing block 13, and the block 17 is engaged with the rack 15, and a gear 16 is rotatably connected to the inner center position of the lower end of the middle group of fixed plates 10, and the outer cylindrical surface of the gear 16 is meshed with the rack 14.

[0041] In view of the problem that the scraper plate 5 on the flotation machine cannot be adjusted, when the liquid level in the flotation machine is too high, the scraper plate 5 is easy to scrape out the liquid in the flotation machine, causing the extraction purity of the copper ore to be greatly reduced. When the liquid level inside the flotation machine is too low, the foam generated is difficult to be scraped out by the scraper plate 5. When the scraper plate 5 needs to be adjusted, the operator pinches the two pressing blocks 13 to compress the first spring 18 and the two pressing blocks 13 slide toward each other at the same time. The sliding of the pressing blocks 13 drives the lower end of the card block 17 to separate from the card rack 15. Because the card rack 15 is connected to the slide bar 29, when the card block 17 is no longer engaged with the card rack 15, the slide bar 29 is no longer fixed. At this time, the operator slides one of the scraper plates 5, and the sliding of the scraper plate 5 drives the slide bar 29 When sliding on the fixed plate 10, because one side of the slide bar 29 is connected to the rack 14, when the slide bar 29 is slid, the gear 16 meshing with the rack 14 and connected thereto will be driven to rotate, and the other side of the gear 16 is meshingly connected to another set of racks 14, so the rotation of the gear 16 drives the rack 14 of the other set to slide in the opposite direction, because the rack 14 of the other set is connected to the slide bar 29 of the other set, and the slide bar 29 of the other set is connected to another set of scraper plates 5, so when the gear 16 drives the rack 14 of the other set to slide in the opposite direction, it will also drive the slide bar 29 and the scraper plates 5 of the other set to slide in the opposite direction, so that when one of the scraper plates 5 is slid, the scraper plates 5 of the other set will be driven to move in the opposite direction, and when sliding to the appropriate position, the operator no longer pinches the two sets of pressing blocks 13, because The rebound force of the first spring 18 will push the two groups of pressing blocks 13 to slide back to back, and at the same time drive the block 17 at the lower end of the pressing block 13 to engage with the card rack 15, so that it brakes the slide bar 29 and the bubble scraper plate 5 is also fixed and cannot move. Then start the first motor 4, and the rotation of the first motor 4 drives the rotating shaft 11 at the output shaft end to rotate, and also drives the fixed plate 10 and the bubble scraper plate 5 fixed on the rotating shaft 11 to rotate together, so that the bubble scraper plate 5 can well scrape the foam floating on the surface of the slurry into the bubble storage tank 9. The open end of the bubble storage tank 9 is connected to the next process, so that it can be processed in a flow-type manner. The present invention realizes the adjustment of the bubble scraper plate 5. When the copper ore slurry level is too low, the surface foam can be well scraped out, which improves the bubble scraping efficiency and can be adjusted according to the height of the slurry level. The different ways of adjusting the bubble scraper plates 5 increase the practicality of the present invention. Compared with the existing method in which the bubble scraper plates 5 and the fixing plates 10 slide through the slide groove and then are fixed with bolts, the present invention drives the other group of bubble scraper plates 5 to slide by sliding any one of the bubble scraper plates 5. Compared with the existing method of adjusting one group of bubble scraper plates 5 and then adjusting the other group of bubble scraper plates 5, the adjustment of the bubble scraper plates 5 of the present invention is more convenient. The adjustment of the prior art cannot ensure that the adjusted sizes of the two are consistent. The present method utilizes the linkage of the two bubble scraper plates 5 to achieve the consistent adjusted sizes of the two groups of bubble scraper plates 5. In addition, the present invention does not need to press the pressing block 13 after adjusting the bubble scraper plates 5 to achieve the fixation of the bubble scraper plates 5. The operation is simple and quick. The prior art also needs to use tools to fix the bolts, which is troublesome and impractical.

[0042] As an embodiment of the present invention, Fig. 9 As shown, arch plates 7 are fixedly connected to both sides of the outer surface of the upper end of the bubble storage tank 9, a scraper 8 is rotatably connected to the outer surface of one side of a group of arch plates 7 near the center position, and one end of the scraper 8 is rotatably connected to the outer surface of another group of arch plates 7.

[0043] During the process of scraping bubbles, the surface of the scraping plate 5 will be formed by the bursting of foam and the refined copper ore slurry will adhere to the surface of the scraping plate 5. If the attached refined copper ore slurry is not cleaned up in time, the weight of the scraping plate 5 will increase as the amount accumulates, which will increase the load of the first motor 4 and reduce the service life of the first motor 4. In order to clean up the refined copper ore slurry attached to the surface of the scraping plate 5 in time, a scraper 8 is rotatably connected between the two groups of arch plates 7. After the scraping plate 5 scrapes the foam into the bubble storage tank 9, it continues to rotate upward. At this time, the scraping surface of the scraping plate 5 that scrapes the foam will contact the scraper 8 and drive the scraper 8 to rotate upward. The scraper 8 rotates to a certain position with the scraping plate 5. Because the bubble scraper plate 5 no longer applies an upward rotational force to the scraper plate 8, the scraper plate 8 will stop at a position and stick to the surface of the bubble scraper plate 5. As the bubble scraper plate 5 rotates, its surface is cleaned. When the bubble scraper plate 5 rotates to no longer contact the scraper plate 8, the scraper plate 8 automatically rotates downward and finally becomes a vertical state, which is convenient for the refined copper ore slurry to slide downward from the surface of the scraper plate 8 and finally drip into the bubble storage tank 9. The present invention realizes that the scraper plate 8 can be cleaned every time the bubble scraper plate 5 rotates to the scraper plate 8, thereby avoiding the problem of the first motor 4 being overloaded due to the excessive weight of the refined copper ore slurry attached to the surface of the scraper plate 5, thereby improving the service life of the first motor 4.

[0044] As an embodiment of the present invention, Fig.10 As shown, a lead block 19 is fixedly connected to the interior of the scraper 8 near the lower end.

[0045] In order to further improve the cleaning effect of the scraper 8 on the surface of the scraper plate 5, a lead block 19 is installed inside the scraper 8 so that when the scraper 8 contacts the scraper plate 5, the weight of the scraper 8 fits more closely to the surface of the scraper plate 5, and the effect of removing the refined copper ore slurry on the surface of the scraper plate 5 is more significant.

[0046] As an embodiment of the present invention, Fig.11As shown, a feed shell 2 is fixedly connected to one side of the upper outer surface of the body 1, a first feed port 3 is fixedly connected to the center position of the upper outer surface of the feed shell 2, a grinding roller 20 is fixedly installed inside the feed shell 2 below the first feed port 3, a discharge port 21 is provided on one side above the grinding roller 20, a filter screen 26 is provided inside the feed shell 2 below the grinding roller 20, a return port 23 is provided inside the feed shell 2 on one side of the filter screen 26, a second motor 25 is fixedly installed inside the feed shell 2 below one side of the return port 23, a screw rod 22 is fixedly connected to the output shaft end of the second motor 25, and a disc 24 is fixedly connected to the lower end of the screw rod 22.

[0047] The copper ore raw material is added to the flotation machine to react with the reagent. However, the quality improvement and impurity reduction treatment efficiency is low because some particles in the copper ore raw material are too large and the reaction time with the reagent is too long. In order to improve the reaction efficiency, a grinding drum 20 is installed below the first feed port 3, so that the copper ore raw material passing through the grinding drum 20 is ground once to make the particles of the copper ore raw material smaller, so that the copper ore reacts with the reagent faster and more fully in the subsequent sequence. The copper ore raw material passing through the grinding drum 20 will finally fall to the filter screen 26 below. The fully ground copper ore raw material will enter the flotation machine through the filter screen 26, and the copper ore raw material that is not fully ground will flow through the filter screen 26. The second motor 25 rotates to drive the screw rod 22 to rotate, so that the coarse copper ore raw materials on the surface of the disc 24 are brought to the discharge port 21 by the screw rod 22, and the coarse copper ore raw materials enter the grinding drum 20 again through the discharge port 21 to be ground again, so that the copper ore particles become smaller to improve the subsequent processing efficiency. The present invention realizes multiple grinding of large-particle copper ore raw materials, making the grinding more sufficient, thereby improving the reaction rate of the subsequent copper ore raw materials and the reagent, and also improves the output rate of copper ore bubbles of the flotation machine, so that the efficiency of the bubble scraping plate 5 on the bubble scraping is also greatly improved.

[0048] As an embodiment of the present invention, Fig.11 and Fig.12 As shown, a plurality of barrier strips 28 are evenly fixedly connected to the outer surface of the upper end of the filter screen 26, and a disassembly mechanism 30 is fixedly connected to the center position of the outer surface of the other side of the filter screen 26, and one end of the disassembly mechanism 30 is fixedly connected to an electric telescopic rod 27, and the electric telescopic rod 27 is fixedly connected to the feed shell 2.

[0049] In order to prevent the filter screen 26 from being blocked during the filtering process and to ensure more complete filtering, the present invention uses the electric telescopic rod 27 to push the filter screen 26 back and forth to achieve better screening, while also avoiding the problem of large particles of copper ore raw materials blocking the filter screen 26 opening. In addition, the barrier strip 28 on the filter screen 26 delays the copper ore raw materials on the filter screen 26 from entering the return material opening 23 along the slope of the filter screen 26, so that the electric telescopic rod 27 pushes the filter screen 26 back and forth to achieve more complete screening.

[0050] As an embodiment of the present invention, Fig.13 As shown, the disassembly mechanism 30 includes a second spring 301, a blocking ring 302, a cavity 303, an L-shaped slide bar 304, a slot 305, and a connecting rod 306; a connecting rod 306 is fixedly installed at the middle position of the outer surface of one side of the filter screen 26, a slot 305 is opened inside one end of the connecting rod 306, the lower end of the slot 305 is an open end, the inside of the slot 305 is snap-connected with the L-shaped slide bar 304, the L-shaped slide bar 304 is slidably connected to the electric telescopic rod 27, a cavity 303 is opened inside one end of the electric telescopic rod 27, the outer surface of the L-shaped slide bar 304 is fixedly connected with a blocking ring 302 near the upper end, and the outer surface of the L-shaped slide bar 304 is sleeved with a second spring 301 near the blocking ring 302.

[0051] After the filter 26 has been used for a period of time, it is necessary to replace the filter 26 because of aging of the material or changes in the mesh port during use that affect the filtering effect. The L-shaped slide bar 304 is pressed to slide the L-shaped slide bar 304 downward, and at the same time, one end of the L-shaped slide bar 304 is driven to separate from the slot 305, so that the filter 26 is connected to the connecting rod 306 and removed together, and then the filter 26 is replaced. When the L-shaped slide bar 304 is pressed, the barrier ring 302 is driven downward to compress the second spring 301, and the cavity 303 provides a movable space for the second spring 301 and the barrier ring 302. The present invention realizes the rapid disassembly of the filter 26 and improves the replacement efficiency of the filter 26.

[0052] Instructions for use: The operator of the present invention pinches the two pressing blocks 13 to compress the first spring 18 and the two pressing blocks 13 slide toward each other at the same time. The sliding of the pressing block 13 drives the block 17 at the lower end to separate from the rack 15. Because the rack 15 is connected to the slide bar 29, when the block 17 is no longer engaged with the rack 15, the slide bar 29 is no longer fixed. At this time, the operator slides one of the bubble scraping plates 5. The sliding of the bubble scraping plate 5 drives the slide bar 29 to slide on the fixed plate 10. Because one side of the slide bar 29 is connected to the rack 14, when the slide bar 29 is slid, the gear 16 meshed with the rack 14 and the gear 16 is driven to rotate. The other side of the gear 16 is meshed with another set of racks 1 4, so the rotation of the gear 16 drives the rack 14 of the other group to slide in the opposite direction, because the rack 14 of the other group is connected to the slide bar 29 of the other group, and the slide bar 29 of the other group is connected to the bubble scraping plate 5 of the other group. Therefore, when the gear 16 drives the rack 14 of the other group to slide in the opposite direction, it will also drive the slide bar 29 and the bubble scraping plate 5 of the other group to slide in the opposite direction at the same time, so that when one of the bubble scraping plates 5 is slid, the bubble scraping plate 5 of the other group will be driven to move in the opposite direction with it. When sliding to the appropriate position, the operator no longer pinches the two groups of pressing blocks 13, because the rebound force of the first spring 18 will push the two groups of pressing blocks 13 to slide in the opposite direction, and at the same time drive the clamping block 17 at the lower end of the pressing block 13 to be clamped with the clamping rack 15 The first motor 4 is then started, and the rotation of the first motor 4 drives the rotating shaft 11 at the output shaft end to rotate, and also drives the fixed plate 10 and the scraping plate 5 fixed on the rotating shaft 11 to rotate together, so that the scraping plate 5 can well scrape the foam floating on the surface of the slurry into the foam storage tank 9, and the open end of the foam storage tank 9 is connected to the next process, so that it can be processed in a flow-type manner. The present invention realizes the adjustment of the scraping plate 5, and when the copper ore slurry level is too low, the surface foam can be well scraped out, which improves the scraping efficiency. The scraping plate 5 can be adjusted according to the height of the slurry level to increase the practicality of the present invention. Compared with the scraping plate The existing method is that the plate 5 and the fixed plate 10 slide through the slide groove and then are fixed with bolts. The present invention drives the other group of scraper plates 5 to slide by sliding any one of the scraper plates 5. Compared with the existing method of adjusting one group of scraper plates 5 and then adjusting the other group of scraper plates 5, the adjustment of the scraper plates 5 of the present invention is more convenient. The adjustment of the prior art cannot ensure that the adjusted sizes of the two are consistent. The present method utilizes the linkage of the two scraper plates 5 to achieve the consistency of the adjusted sizes of the two groups of scraper plates 5. In addition, the present invention does not need to press the pressing block 13 after adjusting the scraper plates 5 to achieve the fixation of the scraper plates 5. The operation is simple and quick. The prior art also needs to use tools to fix the bolts, which is troublesome and impractical.

[0053] The present invention installs a grinding drum 20 below the first feed port 3, so that the copper ore raw material passing through the grinding drum 20 is ground once to make the particles of the copper ore raw material smaller, so that the subsequent reaction speed with the reagent is faster and more complete. The copper ore raw material passing through the grinding drum 20 will finally fall to the filter screen 26 below. The fully ground copper ore raw material will enter the flotation machine through the filter screen 26. The copper ore raw material that is not fully ground will enter the return port 23 along the slope of the filter screen 26 and fall on the outer surface of the disc 24. The second motor 25 rotates The spiral rod 22 is driven to rotate, so that the coarse copper ore raw materials on the surface of the disk 24 are brought to the discharge port 21 by the spiral rod 22, and the coarse copper ore raw materials enter the grinding drum 20 again through the discharge port 21 to be ground again, so that the copper ore particles become smaller to improve the subsequent processing efficiency. The present invention realizes multiple grinding of large-particle copper ore raw materials, making the grinding more sufficient, thereby improving the reaction rate of the subsequent copper ore raw materials and the reagent. The optional models of the first motor 4 and the second motor 25 in the present invention are both: 86BYG250H.
