Description

Technical Field

[0001] This utility model relates to the technical field of flotation machines, and more specifically, to a slurry pretreatment device. Background Technology

[0002] A flotation machine is a mineral processing device, primarily used in the mining industry. The purpose of flotation is to remove various impurities from ores, such as quartz, feldspar, and mica. These impurities affect the properties and quality of graphite in order to obtain a concentrate.

[0003] Currently, various additives, such as collectors, frothers, and modifiers, need to be added to the pulp during mineral flotation. These additives improve the hydrophobic and hydrophilic properties of the minerals, regulate the surface tension of bubbles, and adjust the pH of the pulp, thus providing support for the efficient flotation of graphite.

[0004] In mineral flotation, existing flotation machines generate a large number of bubbles through agitation and aeration. These bubbles can adhere to the surface of the hydrophobic target mineral and then carry it to the surface of the slurry to form a foam layer, while the hydrophilic gangue minerals remain in the slurry, thus achieving mineral separation.

[0005] When using the flotation machine in the above-mentioned existing technology for flotation of flake graphite, various additives and slurry need to be added into the flotation cell for stirring and slurry preparation. Because the amount of slurry is large and the stirring equipment is located at the bottom of the flotation cell, the mixing of additives and slurry takes a long time, so the efficiency is low.

[0006] As can be seen from the above, the low mixing efficiency of the slurry and additives in the existing technology leads to the problem of poor flotation efficiency of the flotation machine. Utility Model Content

[0007] The main objective of this invention is to provide a slurry pretreatment device to solve the problem of poor flotation efficiency in existing flotation machines due to low mixing efficiency of slurry and additives.

[0015] Furthermore, the storage structure includes two partitions spaced apart along the length of the box. The front and rear ends of the partitions are fixedly connected to the box.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0040] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0041] To address the problem of poor flotation efficiency in existing flotation machines due to low mixing efficiency of slurry and additives, this application provides a slurry pretreatment device.

[0042] Among them, such as Figure 1 As shown, the pulp pretreatment device is located on one side of the flotation chamber 20 of the flotation machine. The pulp pretreatment device is connected to the flotation chamber 20 of the flotation machine and is used to provide the pretreated pulp mixed with additives into the interior of the flotation chamber 20. The additives can be collectors, frothers, modifiers, etc.

[0043] In this embodiment, the slurry pretreatment device has a water pump 30, and the flotation chamber 20 has a slurry inlet pipe. One end of the water pump 30 is connected to the outlet end of the slurry pretreatment device through a first pipe body 310, and the other end of the water pump 30 is connected to the slurry inlet pipe through a second pipe body 320. The water pump 30 provides driving force for the slurry to flow from the slurry pretreatment device to the interior of the flotation chamber 20.

[0044] like Figures 2 to 13 As shown, the slurry pretreatment device includes a housing 110, a filter assembly 120, and a feeding assembly 130.

[0045] The top of the box 110 has a slurry inlet 1101, and the side wall has a slurry outlet for communicating with the flotation chamber 20, so that the slurry enters the interior of the box 110 through the slurry inlet 1101, and then is pretreated and mixed with additives inside the box 110 before flowing toward the flotation chamber 20 through the slurry outlet.

[0046] Specifically, such as Figure 3 As shown, the housing 110 includes a base 1110 and a cover plate 1120. The cover plate 1120 covers the top opening of the base 1110. The top plate has a slurry inlet 1101 with the top opening. The side of the base 1110 has a perforation 1102 for the filter assembly 120 to pass through.

[0047] The length direction of the box 110 is Figure 1 As shown in the X direction, the width direction of the box 110 is... Figure 1 As shown in the Y direction, the height direction of the box 110 is... Figure 1 The Z direction is shown.

[0048] In this embodiment, the housing 110 is disposed on one side of the flotation chamber 20. In order to stably dispose of the housing 110 on the side of the flotation machine, a frame 1130 is disposed on the outside of the housing 110. The frame 1130 is used to support and fix the housing 110. The frame 1130 can be connected to the flotation chamber 20 by fasteners, such as bolts.

[0049] In this embodiment, the number of tanks 110 can be set adaptively as needed, such as one, two, three, etc. Multiple tanks 110 are provided, and multiple tanks 110 are supplied with slurry to the interior of the flotation chamber 20 through a water pump 30.

[0050] like Figure 2 and Figure 4 As shown, the number of feeding components 130 and filtering components 120 is equal to the number of housings 110, and each is equipped with a housing 110; that is, the feeding components 130 and filtering components 120 are both located inside the housing 110.

[0051] Specifically, the filter assembly 120 of this application has a first part disposed inside the housing 110 and a second part disposed outside the housing 110. The first part is disposed below the slurry inlet 1101 and is magnetic, so that the slurry entering the housing 110 from the slurry inlet 1101 flows to the filter assembly 120, thereby ensuring that the filter assembly 120 can fully pre-treat the slurry entering the housing 110 and adsorb magnetic easily floatable minerals such as iron sulfide onto the filter assembly 120 through magnetism.

[0052] The filter assembly 120 of this application is disposed in the part inside the housing 110 for filtering mineral slurry, and the second part extends out of the housing 110 through the through hole 1102, so that the magnetic minerals filtered out on the filter assembly 120 can be transported to the outside of the housing 110 to achieve the effect of removing impurities, thereby facilitating the recycling of the filter assembly 120 and improving the efficiency of the mineral slurry pretreatment device.

[0053] Specifically, the height of the second part is greater than that of the first part to form an inclined structure. This arrangement ensures that the slurry entering the interior of the housing 110 will come into contact with the first part. Since the second part is higher than the first part, the slurry can be prevented from flowing out of the second part.

[0054] like Figures 4 to 8 As shown, the feeding assembly 130 is disposed below the filter assembly 120. The feeding assembly 130 includes a storage structure and a spraying structure. The storage structure is disposed inside the housing 110 and has an additive cavity for containing additives. A slurry cavity is formed between the storage structure and the inner wall of the housing 110 along the length direction of the housing 110. The slurry inlet 1101 and the slurry outlet are connected to the slurry cavity. The spraying structure can be disposed on the storage structure and / or the housing 110 for fixing the spraying structure. The liquid inlet of the spraying structure is connected to the additive cavity, and the output end of the spraying structure is connected to the slurry cavity.

[0055] Specifically, the first part blocks the top opening of the additive chamber of the feeding assembly 130 to prevent the slurry from flowing directly into the slurry chamber. The slurry pretreatment device of this application adopts independently set slurry chamber and additive chamber to ensure that the slurry does not flow into the additive chamber, thus avoiding the problem that the slurry directly enters the additive chamber and cannot be fully mixed with the additive. Moreover, the direct entry of the slurry into the slurry chamber is conducive to the smooth flow of the slurry, thereby improving the pretreatment effect of the slurry pretreatment device.

[0056] In this embodiment, the slurry pretreatment device of this application uses a filter assembly 120 and a feeding assembly 130 in combination to enable the slurry to enter the slurry chamber after pretreatment by the filter assembly 120. The additives inside the additive chamber of the storage structure are sprayed towards the slurry chamber through the spray structure and mixed with the slurry. The spray structure is designed to facilitate full contact between the additives and the slurry, thereby achieving mixing of the pretreated slurry and the additives. At the same time, it removes easily floating minerals, reduces the impact of easily floating minerals on the grade of graphite concentrate, and saves the time of mixing the additives and the slurry.

[0057] like Figures 9 to 13 As shown, the filter assembly 120 includes a ring belt, multiple rollers, a drive element, and a magnetic element 1260. The first end of the ring belt 1210 is disposed inside the housing 110, and the second end of the ring belt 1210 extends to the outside of the housing 110. Multiple rollers are disposed inside the ring belt 1210 and extend along the length of the housing 110. The multiple rollers include a drive roller 1230, a driven roller 1220, and a mounting roller 1240 disposed between the drive roller 1230 and the driven roller 1220. The ends of roller 230 and driven roller 1220 are rotatably connected to housing 110 via bearing seat 12110. The first end of annular belt 1210 is sleeved on drive roller 1230, and the second end of annular belt 1210 is sleeved on driven roller 1220. Driven roller 1220 and mounting roller 1240 are disposed inside housing 110. Drive roller 1230 is disposed outside housing 110 to form a second part. Drive member is drivenly connected to drive roller 1230. Magnetic member 1260 is disposed inside mounting roller 1240.

[0058] The magnetic component 1260 can be a magnet. By setting the magnetic component 1260 inside the tubular mounting roller 1240, the mounting roller 1240 becomes magnetic. Multiple mounting rollers 1240 are arranged sequentially along the length of the annular belt 1210. The multiple mounting rollers 1240 cooperate to form a magnetic attraction area. The magnetic attraction area formed by the multiple mounting rollers 1240 inside the annular belt 1210 has a magnetic attraction effect, which is used to magnetically fix the magnetic mineral to the top surface of the annular belt 1210. When the annular belt 1210 moves the magnetic mineral to the outside of the box 110, there are no mounting rollers 1240 outside the box 110, that is, there is no corresponding magnetic attraction force. Therefore, the magnetic mineral falls off under the action of gravity.

[0059] Specifically, the driving component is a motor, which drives the active roller 1230 to rotate. The active roller 1230 drives the annular belt 1210 and the driven roller 1220 to rotate. Under the driving action of the driving component, the annular belt 1210 maintains rotation. The annular belt 1210 of this application has scrapers, which are arranged along the length direction of the housing 110. Multiple scrapers are arranged at intervals along the rotation direction of the annular belt 1210. The arrangement of the scrapers facilitates the conveying of magnetic minerals to the outside of the housing 110. The scraper structure of this application improves the stability of magnetic mineral conveying.

[0060] In this embodiment, the slurry inlet 1101 extends along the width direction of the box body 110, and the annular belt 1210 is wider than the slurry inlet 1101 along the width direction of the box body 110. The projection of the slurry inlet 1101 along the height direction of the box body 110 is located inside the area of ​​the annular belt 1210. Therefore, the slurry falling from the slurry inlet 1101 falls directly onto the annular belt 1210. The width of the annular belt 1210 is smaller than the width of the box body 110, so the slurry on the annular belt 1210 flows into the slurry chamber along the width direction of the annular belt 1210. The housing 110 of this application is provided with a brush roller that contacts the second end of the annular belt 1210. The two ends of the brush roller are detachably mounted on the frame through bearing seats. The frame is connected to the frame 1130 on the housing 110. Therefore, the brush roller is stably installed. At the same time, a motor is connected and installed at the end of the brush roller through a coupling or other device. When it is necessary to clean the annular belt 1210, the brush roller can be controlled to rotate under the operation of the motor to achieve the cleaning of the annular belt 1210.

[0061] like Figures 9 to 13 As shown, both the driving roller 1230 and the driven roller 1220 include two roller segments spaced apart along the length of the housing 110. A plurality of mounting rollers 1240 are disposed at the first end of the annular belt 1210, forming a first roller body. The first roller body is disposed between the two roller segments of the driving roller 1230 and is rotatably connected to the roller segments. Among the plurality of mounting rollers 1240, the one disposed at the second end of the annular belt 1210 is a second roller body. The second roller body is disposed between the two roller segments of the driven roller 1220 and is rotatably connected to the roller segments.

[0062] The two sections of the drive roller 1230 are connected to the housing 110 at opposite ends via bearing seat 12110. At least one of the sections is equipped with a drive element that drives the drive roller 1230 to rotate. The two sections of the driven roller 1220 are connected to the housing 110 at opposite ends via bearing seat 12110.

[0063] The filter assembly 120 also includes annular end plates 1270 and brackets 1250. Annular end plates 1270 are fixedly provided at both ends of each mounting roller 1240. Brackets 1250 are provided on both sides of the axial direction of the multiple mounting rollers 1240. The brackets 1250 are connected to the multiple annular end plates 1270 on the same side of the multiple mounting rollers 1240. The multiple mounting rollers 1240 form an integral installation through the brackets 1250. The two roller segments of the driving roller 1230 are rotatably connected to the brackets 1250 at their mutually facing ends. The two roller segments of the driven roller 1220 are rotatably connected to the brackets 1250 at their mutually facing ends.

[0064] Specifically, the structure of the annular end plate 1270 and the bracket 1250 is adopted to form multiple mounting rollers 1240 into a single mounting unit, which helps to improve the installation stability of the mounting rollers 1240 and thus form a stable magnetic attraction effect.

[0065] It is understood that multiple annular end plates 1270 located on the same side of the mounting roller 1240 are fixedly connected by a bracket 1250, and the bracket 1250 is provided to fix the multiple mounting rollers 1240 together.

[0066] Furthermore, the filter assembly 120 also includes an annular connecting plate 1280 and a detachable annular plate 1290. The ends of the two roller segments of the drive roller 1230 and the two roller segments of the driven roller 1220 facing each other are provided with an annular connecting plate 1280. The detachable annular plate 1290 is fixedly connected to the annular connecting plate 1280. The detachable annular plate 1290 has a central shaft, which is rotatably connected to the bracket 1250 through a bearing.

[0067] The active roller 1230 and the driven roller 1220 are rotatably connected to the bracket 1250 through the annular connecting plate 1280 and the detachable ring plate 1290, so that the mounting roller 1240 can be stably set inside the annular belt 1210 during the rotation of the active roller 1230 and the driven roller 1220, so as to avoid affecting the magnetic attraction effect.

[0068] like Figure 13 As shown, the filter assembly 120 also includes a connecting plate 12120, a support tube 12150, and a threaded rod 12160. The connecting plate 12120 is disposed at the bottom of the bearing seat 12110 connected to the drive roller 1230. The connecting plate 12120 has a sleeve hole 12130 and a threaded hole 12140. The support tube 12150 is disposed on the housing 110. The support tube 12150 passes through the sleeve hole 12130 and is slidably engaged with the sleeve hole 12130. The end of the threaded rod 12160 is connected to the end of the support tube 12150 through a bearing. The threaded rod 12160 passes through the threaded hole 12140 and is rotatably engaged with the threaded hole 12140.

[0069] Specifically, the inlet 1101 of the box body 110 of different models has different dimensions, so a ring belt 1210 of corresponding length is required. The multiple rollers of this application can be adapted to ring belts 1210 of different lengths by adjusting the position of the drive roller 1230.

[0070] In order to ensure that the adjusted drive roller 1230 maintains the driving connection with the drive component, the drive component is set on the mounting plate. Of course, it is not limited to setting the drive component on the mounting plate. Alternatively, the drive component can be adapted to the position of the drive roller 1230 and installed on the housing 110 to ensure the driving connection between the drive component and the drive roller 1230.

[0071] In this embodiment, by controlling the rotation of the threaded rod 12160, the connecting plate 12120 is driven to move. The connecting plate 12120 drives the bearing seat 12110 and the drive roller 1230 to move. The support tube 12150 and the threaded rod 12160 extend along the width direction of the housing 110, thereby ensuring that the connecting plate 12120 slides along the extension direction of the support tube 12150 when it moves, thus improving the accuracy of the movement.

[0072] like Figure 4 and Figure 5 As shown, the storage structure includes a partition 1310. Two partitions 1310 are provided and spaced apart along the length of the box 110. The front end and rear end of the partition 1310 are fixedly connected to the box 110. Two slurry chambers are formed between the partition 1310 and the inner wall of the box 110 along the length of the box 110. The filter assembly 120 blocks the top opening formed between the two partitions 1310.

[0073] The structure of the two partitions 1310 forms two slurry chambers spaced apart along the width of the box 110 between them and the inner wall of the box 110. The slurry from the slurry inlet 1101 flows to both sides along the width of the annular belt 1210 after passing through the filter assembly 120 and enters the slurry chamber.

[0074] The storage structure also includes multiple hoppers 1320, which are located in the area between two partitions 1310. The multiple hoppers 1320 are spaced apart along the height of the box 110. Each hopper 1320 forms an additive chamber. A flow channel 1321 is formed at the bottom of the hopper 1320, and the flow channel 1321 is connected to the liquid inlet end of the spray structure.

[0075] Specifically, the silo 1320 is located in the area between the two partitions 1310. Under the shielding effect of the annular belt 1210 of the filter assembly 120, the slurry will not flow into the silo 1320, thus ensuring that the additives inside the silo 1320 will not come into direct contact with the slurry, which would lead to uneven mixing.

[0076] In this embodiment, multiple silos 1320 arranged along the height direction can hold different types of additives, thereby facilitating the spraying contact between the slurry and various additives. Each silo 1320 is equipped with a liquid inlet pipe 1323 and a connecting pipe 1324 that communicates with the spraying structure. External adjustment equipment can add additives to the inside of the silo 1320 through the liquid inlet pipe 1323, and the connecting pipe 1324 communicates with the spraying structure to supply liquid.

[0077] In this embodiment, a flow channel 1321 is provided at the bottom of the silo 1320 to facilitate the flow of additives inside the silo 1320 toward the spray structure through the flow channel 1321, which is beneficial to improving the flow efficiency of the additives.

[0078] like Figure 6 and Figure 7 As shown, the storage structure also includes ear plates 1322 and support frames 1330. The ear plates 1322 are disposed on the hopper 1320 and have through holes. The support frames 1330 are disposed on the housing 110 and have multiple trays 1331 spaced apart along the height direction. The trays 1331 are disposed one-to-one with the hopper 1320. The top surface of the trays 1331 has a protruding structure 1332. The ear plates 1322 are supported on the top surface of the trays 1331 and the protruding structure 1332 extends into the interior of the through holes.

[0079] In this embodiment, the support plate 1331 is used to support the ear plate 1322, and in order to improve the stability of the support, the support plate 1331 and the ear plate 1322 are limited by a protruding structure 1332 and a through hole insertion structure.

[0080] like Figure 5 and Figure 8 As shown, the spray structure includes multiple spray units, which are spaced apart along the height of the box 110 and correspond one-to-one with multiple silos 1320. The spray units can spray the additives inside the corresponding silos 1320 into the slurry chamber and make them contact the slurry.

[0081] Multiple spray units can work independently or simultaneously.

[0082] Specifically, the spraying unit includes a motor 1350, a pump body 1360, and spray pipes 1390. The motor 1350 is located outside the housing 110 and is fixedly connected to the housing 110; the pump body 1360 is located outside the housing 110 and is fixedly connected to the housing 110, and the motor 1350 is driven by the pump body 1360. The liquid input end of the pump body 1360 is connected to the silo 1320; two spray pipes 1390 are provided. One end of each spray pipe is respectively installed in two slurry chambers and connected to the inner wall of the box 110. The other end of each spray pipe is connected to the liquid output end of the pump body 1360. The other end of each spray pipe is connected to the main body 1370 through a third pipe 1380. The third pipe 1380 penetrates the box 110. The main body 1370 is connected to the pump body 1360. The additive inside the main body 1370 is diverted and flows to the two spray pipes 1390.

[0083] In this embodiment, the motor 1350 drives the pump body 1360 to work. The pump body 1360 is a water pump. The pump body 1360 provides driving force for the additive to be sprayed from the hopper 1320 along the spray pipe 1390 into the interior of the slurry chamber. The structure of the two spray pipes 1390 achieves uniform spraying into the two slurry chambers. In order to improve the controllability of the structure, a control valve 1340 is provided on the spray pipe 1390 to control the on / off state of the spray pipe 1390. A controller is provided on the outer side of the housing 110. The controller is connected to the motor 1350 and the pump body 1360 by signal connection and is used to control the working state of the motor 1350 and the pump body 1360.

[0084] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0085] The slurry pretreatment device of this application uses a filter assembly 120 and a feeding assembly 130 in combination to enable the slurry to enter the slurry chamber after pretreatment by the filter assembly 120. The additives inside the additive chamber of the storage structure are sprayed towards the slurry chamber through the spray structure and mixed with the slurry. The spray structure is designed to facilitate full contact between the additives and the slurry, realize the mixing of the pretreated slurry and the additives, remove easily floating minerals, reduce the impact of easily floating minerals on the grade of graphite concentrate, and save the time of mixing the additives and the slurry.

[0086] The filter assembly 120 of this application has a portion inside the housing 110 for filtering mineral slurry, and another portion extends out of the housing 110, which facilitates the transport of magnetic minerals filtered out on the filter assembly 120 to the outside of the housing 110, thereby achieving the effect of removing impurities. This facilitates the recycling of the filter assembly 120 and improves the efficiency of the mineral slurry pretreatment device.

[0087] The slurry pretreatment device of this application adopts independently set slurry chamber and additive chamber to ensure that the slurry does not flow into the additive chamber, thus avoiding the problem that the slurry directly enters the additive chamber and cannot be fully mixed with the additive. Moreover, the direct entry of the slurry into the slurry chamber is conducive to the smooth flow of the slurry, thereby improving the pretreatment effect of the slurry pretreatment device.
