Description

Technical Field

[0001] This utility model relates to the technical field of flotation equipment components, and more specifically, to a flotation scraper device. Background Technology

[0002] Flotation is a process that separates desired solid particles from a mixture by utilizing the differences in the physicochemical properties of the solid particle surfaces. It is widely used in mining, wastewater treatment, and resource recovery. In froth flotation, the target particles are first made hydrophobic by a trapping agent, then the target particles combine with air bubbles to float. Once the bubbles reach the liquid surface, they form foam, which is collected to obtain the target particles.

[0003] In existing flotation equipment, foam overflows from the top of the flotation cell and is collected. Some flotation cells also have scrapers at the top, which rotate on the liquid surface to remove and collect foam. However, scrapers are usually fixed above the flotation cell, making it inconvenient for operators to enter the cell for maintenance. In addition, the scrapers are suspended horizontally for a long time, and the shear stress caused by their own weight can easily cause them to bend or even break, which is not conducive to the long-term use of the equipment. Utility Model Content

[0004] This utility model provides a flotation scraper device to overcome the problems in the prior art, such as the inconvenience of fixed scrapers for operators to enter the flotation cell for maintenance, and the easy bending or even breakage of scrapers when suspended horizontally for a long time.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a flotation scraper device, including a central rotating component and a scraper assembly, wherein the scraper assembly is hinged to the central rotating component, the scraper assembly is capable of rotating in the vertical and horizontal directions, and a float is provided on the scraper assembly.

[0006] In this invention, the flotation scraper device is installed in the flotation cell. A central rotating component drives the scraper assembly to rotate, scraping away the foam on the top of the liquid surface for collection. When no liquid is injected into the flotation cell and the scraper device is not in operation, the scraper assembly hangs naturally under gravity. When liquid is injected into the flotation cell and the device is in operation, a float gradually lifts the other end of the scraper assembly, causing it to float horizontally on the liquid surface to scrape away the foam. After the liquid is discharged from the flotation cell, the scraper assembly returns to its vertical position as the liquid level drops. This design, by incorporating a scraper assembly that floats with the liquid surface, not only effectively removes foam during normal operation but also allows for easy access for maintenance personnel when not in operation. Furthermore, the vertical position of the scraper assembly reduces shear stress caused by its own weight compared to a horizontal position, extending its service life and improving economic efficiency.

[0007] Furthermore, the scraper assembly includes a chute, a lifting movable column, and a scraper plate. The chute is fixedly connected to the central rotating member and has a groove extending vertically. One end of the lifting movable column is located in the extending direction of the groove and is hinged to the central rotating member. The other end of the lifting movable column is hinged to the scraper plate. The scraper plate is rotatable in both the vertical and horizontal directions. The float is disposed on the scraper plate.

[0008] In this design, the skimmer is used to directly contact and scrape off the foam. The skimmer is indirectly hinged to the central rotating component by the lifting movable column. When the flotation skimmer device is in operation, the skimmer is horizontally suspended on the liquid surface. At this time, the chute, the lifting movable column and the skimmer form a triangular structure, which can improve the structural strength of the skimmer assembly, ensure the working reliability of the skimmer assembly, extend the service life of the skimmer assembly and improve economic efficiency.

[0009] Furthermore, multiple scraper assemblies are provided, and each scraper assembly is evenly distributed around the central rotating member in the circumference.

[0010] In this solution, by evenly arranging multiple scraper assemblies, the effect of scraping off foam can be improved, making it easier to collect the foam.

[0011] Furthermore, it also includes a rotation limiting member, which is disposed at the upper end of the slide groove and fixedly connected to the central rotating member. The rotation limiting member is provided with a first shaft, and the end of the lifting movable column facing the rotation limiting member is provided with a first rotating collar, which is rotatably connected to the first shaft.

[0012] In this design, one end of the lifting movable part is rotatably connected to the central rotating part by a rotating limiting component, which facilitates assembly, disassembly and replacement.

[0013] Furthermore, a second shaft is provided in the middle of the slag scraper, and a second rotating collar is provided at one end of the lifting movable column facing the slag scraper, and the second rotating collar is rotatably connected to the second shaft.

[0014] In this design, the rotatable connection between the scraper and the lifting movable column is achieved through the rotatable connection of the second shaft and the second rotating collar.

[0015] Furthermore, a roller is rotatably connected to one end of the slag scraper facing the chute, and the roller is rolled within the chute.

[0016] In this design, rollers roll within the trough, thereby enabling one end of the skid plate to move vertically and connect with the sliding chute.

[0017] Furthermore, it also includes a rotating shaft, with the central rotating component rotatably connected to the rotating shaft on the same axis, and the rotating shaft having multiple blades connected circumferentially.

[0018] In this scheme, a rotating shaft and paddles are used to agitate and mix the liquid in the flotation cell, thereby promoting the generation and collection of foam.

[0019] Furthermore, it also includes a drive motor, which is connected to both the central rotating component and the rotating shaft, and the rotating shaft rotates in the opposite direction to the central rotating component.

[0020] In this scheme, a drive motor is set to drive the central rotating component and the rotating shaft to rotate, thereby driving the scraper assembly and the blade to rotate, scraping off the foam on the top of the liquid surface for collection. By setting the central rotating component and the rotating shaft to rotate in opposite directions, the scraper assembly and the blade rotate in opposite directions. This can both promote the disturbance of the liquid in the flotation cell by the rotation of the blade and promote the collection of foam by the oppositely rotating scraper assembly.

[0021] Furthermore, the blade has multiple air holes inside, and the shaft has air passages inside, which are connected to each of the air holes.

[0022] In this scheme, external gas enters the liquid in the flotation cell through air channels and pores, promoting the generation of foam for easy collection.

[0023] Furthermore, it also includes a mounting assembly for fixed connection with an external device, the shaft being rotatably connected to the mounting assembly.

[0024] In this solution, the flotation scraper device is connected to external equipment such as a flotation cell by means of an installation component. Since the installation component is rotatably connected to the rotating shaft, it will not affect the normal rotation of the flotation scraper device during operation.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] I. The flotation scraper device of this utility model, by setting a scraper that floats with the liquid surface, can not only remove the foam on the liquid surface during normal operation, but also facilitate the entry of personnel into the flotation tank for maintenance when not in operation. At the same time, the vertical position of the scraper can reduce the shear stress generated by its own weight compared with the horizontal position, thus extending the service life of the scraper frame and improving economic efficiency.

[0027] II. The flotation scraper device of this utility model, by setting a rotating shaft and blades, facilitates the mixing of liquid in the flotation cell, promotes the generation and collection of foam, and improves the flotation effect.

[0028] Third, the flotation scraper device of this utility model, by setting a central rotating component and a rotating shaft with opposite rotation directions, makes the scraper assembly rotate in the opposite direction to the blade, which promotes the disturbance of the liquid in the flotation cell and thus helps to collect the foam.

[0029] IV. The flotation scraper device of this utility model opens air channels and air holes in the rotating shaft and the blade to facilitate the introduction of reactant, scavenging agent and air into the bottom of the flotation cell to form mixed bubbles. The bubbles are evenly distributed in the flotation cell as the blade rotates, thereby improving the flotation effect. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0044] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0045] Example 1

[0046] refer to Figures 1 to 11 This embodiment discloses a flotation scraper device, including a central rotating part 1 and a scraper assembly 2. The scraper assembly 2 is hinged to the central rotating part 1. The scraper assembly 2 can rotate in the vertical and horizontal directions. A float 231 is provided on the scraper assembly 2.

[0047] In this embodiment, during use, the flotation scraper device is installed in the flotation cell 100. The central rotating component 1 drives the scraper assembly 2 to rotate, thereby scraping away the foam on the top of the liquid surface for collection. When no liquid is injected into the flotation cell 100 and the flotation scraper device is not in operation, the scraper assembly 2 hangs naturally under gravity. When liquid is injected into the flotation cell 100 and the flotation scraper device is in operation, the float 231 drives the other end of the scraper assembly 2 to gradually rise, causing the scraper assembly 2 to float horizontally on the liquid surface to scrape away the foam. After the liquid is discharged from the flotation cell 100, the scraper assembly 2 returns to its vertical position as the liquid level drops. This solution, by setting the scraper assembly 2 to float with the liquid surface, can both perform the function of scraping away foam during normal operation and facilitate personnel access to the flotation cell 100 for maintenance when not in operation. Furthermore, the vertical position of the scraper assembly 2 reduces the shear stress generated by its own weight compared to the horizontal position, extending the service life of the scraper assembly 2 and improving economic efficiency.

[0048] refer to Figure 2 The scraper assembly 2 includes a chute 21, a lifting movable column 22, and a scraper plate 23. The chute 21 is fixedly connected to the central rotating component 1 and has a groove 211 extending vertically. One end of the lifting movable column 22 is located in the extending direction of the groove 211 and is hinged to the central rotating component 1. The other end of the lifting movable column 22 is hinged to the scraper plate 23. The scraper plate 23 can rotate in both the vertical and horizontal directions. The float 231 is disposed on the scraper plate 23.

[0049] In this embodiment, the skimmer 23 is used to directly contact and scrape off the foam. The skimmer 23 is indirectly hinged to the central rotating component 1 by the lifting movable column 22. When the flotation skimmer device is in operation, the skimmer 23 is horizontally suspended on the liquid surface. At this time, the chute 21, the lifting movable column 22, and the skimmer 23 form a triangular structure, which improves the structural strength of the skimmer assembly 2, ensures the working reliability of the skimmer assembly 2, and extends the service life of the skimmer assembly 2. (Reference) Figure 11 The float can be hollow.

[0050] This embodiment features a floating skimmer 23 that moves with the liquid surface. This skimmer can remove foam from the liquid surface during normal operation and also allows workers to easily access the flotation tank for maintenance when not in operation. Furthermore, the vertical skimmer 23 reduces the shear stress caused by its own weight compared to the horizontal skimmer, thus extending the service life of the skimmer frame and improving economic efficiency.

[0051] refer to Figure 4The central rotating component 1 can be approximately circular, and it can rotate around a vertical axis, thereby driving the scraper assembly 2 to rotate in the horizontal plane. In use, the central rotating component 1 can be directly or indirectly connected to a drive mechanism, thus being driven to rotate. The upper end of the sliding groove component 21 is fixedly connected to the central rotating component 1, and the central rotating component 1 can drive the sliding groove component 21 to rotate around its axial direction. The sliding groove component 21 has a groove 211 extending vertically outwards, and the end of the scraper 23 facing the central rotating component 1 is movably connected in the groove 211, wherein the moving connection can be a sliding connection or a rolling connection.

[0052] The two ends of the lifting column 22 are hinged to the central rotating component 1 and the middle of the scraper plate 23, respectively. (Reference) Figure 6 When the skimmer 23 is opened, a triangular structure is formed between the lifting column 22, the skimmer 23, and the sliding groove 21, with the skimmer 23 positioned approximately horizontally. The upward-facing side of the skimmer 23 has a hollow design to reduce its own weight and provide rotation space for the lifting column 22. (Reference) Figure 4 When the slag scraper 23 is retracted and vertical, the slag scraper 23 is set in a roughly vertical position.

[0053] refer to Figure 4 Multiple scraper assemblies 2 are provided, and each scraper assembly 2 is evenly distributed around the central rotating member 1 in the circumference. In this embodiment, three scraper assemblies 2 are provided, and each scraper assembly 2 is distributed horizontally at approximately 120° intervals around the central rotating member 1 in the circumference. By evenly arranging multiple scraper assemblies 2, the effect of scraping off foam can be improved, so as to facilitate foam collection.

[0054] refer to Figures 3 to 5 The flotation scraper device in this embodiment also includes a rotation limiting member 3. The rotation limiting member 3 is disposed at the upper end of the slide chute 21 and fixedly connected to the central rotating member 1. The rotation limiting member 3 is provided with a first shaft 31, and a first rotating collar 221 is provided at one end of the lifting movable column 22 facing the rotation limiting member 3. The first rotating collar 221 is rotatably connected to the first shaft 31. The rotation limiting member 3 rotatably connects one end of the lifting movable member to the central rotating member 1, which facilitates assembly, disassembly and replacement. At the same time, the lifting movable member provides rotational power to the scraper.

[0055] Specifically, one end of the rotation limiting member 3 is fixedly connected to the circumferential outer side of the central rotating member 1, and the other end of the rotation limiting member 3 is provided with a rotation mounting groove facing outward. The first shaft body 31 is horizontally arranged in the rotation mounting groove, and the first rotating collar 221 is indirectly rotatably connected to the first shaft body 31 through an internal bearing structure and can rotate in the up and down direction.

[0056] refer to Figure 5The scraper plate 23 has a second shaft 232 in its middle. The lifting column 22 has a second rotating collar 222 at one end facing the scraper plate 23. The second rotating collar 222 is indirectly rotatably connected to the second shaft 232 via an internal bearing structure. This rotatable connection between the scraper plate 23 and the lifting column 22 is achieved through the rotational connection of the second shaft 232 and the second rotating collar 222. The upper end of the lifting column 22 is rotatably connected to the rotation limiter 3, and the lower end of the lifting column 22 is rotatably connected to the middle of the scraper plate 23.

[0057] refer to Figures 3 to 7 The end of the skimmer 23 facing the slide 21 is rotatably connected to a roller 233, and the roller 233 has a bearing structure inside so that it can be rolled in the trough 211. In this embodiment, the roller 233 rolls in the trough 211, thereby realizing the movable connection between one end of the skimmer 23 and the slide 21.

[0058] Example 2

[0059] refer to Figure 1 This embodiment is similar to Embodiment 1, except that in this embodiment, the flotation scraper device further includes a drive motor 4 and a rotating shaft 5, with the drive motor 4 and the rotating shaft 5 being connected in a transmission manner. Multiple blades 6 are connected circumferentially to the bottom of the rotating shaft 5. For example, in this embodiment, four blades 6 are evenly distributed circumferentially on the rotating shaft 5, with adjacent blades 6 arranged at approximately a 90° angle.

[0060] Specifically, refer to Figures 1 to 3 The fixed end of the drive motor 4 can be fixed to an external fixed object. The motor output shaft 41 of the drive motor 4 is connected to the rotating shaft 5 through the transmission mechanism 8. The drive motor 4 drives the rotating shaft 5 to rotate, thereby driving the blade 6 to rotate. In this embodiment, gear transmission is used, wherein the transmission mechanism 8 includes at least a first driving gear 81 and a first driven gear 83, both of which are external gears. The first driving gear 81 is coaxially fixedly connected to the motor output shaft 41, and the first driven gear 83 is tightly fixed to the outside of the rotating shaft 5. The transmission mechanism 8 drives the rotating shaft 5 to rotate through the meshing of the first driving gear 81 and the first driven gear 83. By setting the rotating shaft 5 and the blade 6, the liquid in the flotation tank 100 is stirred and mixed with the reactant, scavenging agent, and aeration air, promoting the generation and collection of foam.

[0061] refer to Figure 9 and Figure 10The blade 6 is hollow inside, and its bottom is connected to multiple air holes 61. The rotating shaft 5 has an air passage 51 inside, which is connected to the hollow structure of the blade 6. The reactant, scavenging agent, and aeration gas added through the rotating shaft 5 can enter the liquid in the flotation tank through the air passage 51 and air holes 61, reacting with heavy metal ions in the liquid to form a mixture of froth. Under the rotation of the blade, the liquid in the flotation tank will swirl, allowing the reactant, scavenging agent, and aeration gas to diffuse evenly and rapidly into the liquid. The swirling flow prolongs their residence time in the liquid, thereby increasing the froth generation rate, increasing the froth collection volume, and ultimately improving the heavy metal recovery rate from the liquid.

[0062] refer to Figure 9 and Figure 10 The bottom of the rotating shaft 5 is connected to a flow divider 62. The blades have a hollow interior and the rotating shaft 5 is connected to each blade 6 via the flow divider 62. The interior of the flow divider 62 is connected to the air passage 51 and the air hole 61. In this design, a drive motor 4 drives the rotating shaft 5 to rotate, which in turn drives the blades 6 to rotate. This allows the reactant, scavenging agent, and aeration air to be diffused into the liquid in the pool through the rotating shaft 5, blades 6, flow divider 62, and air hole 61 to produce the desired mixture of foam.

[0063] Example 3

[0064] refer to Figure 8 as well as Figures 1 to 3 This embodiment is similar to embodiment 2, except that the central rotating part 1 is coaxially rotatably connected to the rotating shaft 5, and the central rotating part 1 is connected to the motor output shaft 41 of the drive motor 4 through the transmission mechanism 8.

[0065] Specifically, the central rotating component 1 can be annular in shape, with a support column 11 connected to its upper end. The second driven gear 84 is fixed above the central rotating component 1 via the support column 11. The central rotating component 1 is connected to the rotating shaft 5 via a bearing. The inner ring of the bearing is fixedly connected to the rotating shaft 5, and the outer ring of the bearing is fixedly connected to the central rotating component 1. Due to the rotational characteristics of the bearing, the rotation direction of the rotating shaft 5 can be different from the rotation direction of the central rotating component 1.

[0066] refer to Figure 3 The drive motor 4 is connected to the rotating shaft 5 and the central rotating component 1 via the transmission mechanism 8. The rotating shaft 5 and the central rotating component 1 rotate in opposite directions. By setting the central rotating component 1 and the rotating shaft 5 to rotate in opposite directions, the scraper assembly 2 and the blade 6 rotate in opposite directions. This not only promotes the disturbance of the liquid in the flotation cell through the rotation of the blade, but also promotes the collection of foam through the counter-rotating scraper assembly.

[0067] Specifically, in this embodiment, the motor output shaft 41 of the drive motor 4 is connected to the rotating shaft 5 via a first driving gear 81 and a first driven gear 83. Both the first driving gear 81 and the first driven gear 83 are external gears, and they transmit power through external meshing. Therefore, the rotation directions of the first driving gear 81 and the first driven gear 83 are opposite. The second driving gear 82 meshes with the second driven gear 84, but the second driven gear 84 is an internal ring gear. The second driving gear 82 and the second driven gear 84 are internally meshed, so the rotation directions of the second driving gear 82 and the second driven gear 84 are the same. The first driving gear 81 and the second driving gear 82 are both coaxially fixedly connected to the motor output shaft 41, so the first driving gear 81 and the second driving gear 82 can rotate in the same direction. Since the first driven gear is an external gear and the second driven gear is an internal gear, the first driven gear and the second driven gear will rotate in opposite directions. Through the transmission action, the rotating shaft 5 and the central rotating part 1 will rotate in opposite directions, thereby driving the paddle 6 and the scraper assembly 2 to rotate in opposite directions, promoting the collection of foam.

[0068] In this embodiment, the radii of the first driving gear 81, the first driven gear 83, the second driving gear 82, and the second driven gear 84 can be different, resulting in different rotational speeds between the blade 6 and the scraper assembly 2. For example, when the first driving gear 81 and the second driving gear 82 rotate one revolution, the first driven gear 83 rotates one revolution, and the second driven gear 84 rotates 0.12 revolutions, and their rotation directions are opposite. Therefore, the reverse speed of the first driven gear 83 is approximately 8.3 times the rotational speed of the second driven gear 84. Through the transmission effect, the reverse speed of the rotating shaft 5 is approximately 8.3 times the rotational speed of the central rotating component 1, which will further improve the foam collection efficiency.

[0069] refer to Figure 1 A mounting assembly 7 is rotatably connected to the top of the rotating shaft 5, and the mounting assembly 7 is used for fixed connection with external equipment. In this solution, the rotating shaft 5 and the flotation scraper device on the rotating shaft 5 are connected to external equipment such as a flotation cell through the mounting assembly 7. Since the mounting assembly 7 is rotatably connected to the rotating shaft 5, it will not affect the normal rotation of the flotation scraper device during operation.

[0070] Specifically, in this embodiment, the mounting assembly 7 includes a crossbeam 71, a fixing column 72, and a connecting bearing 73. Both ends of the crossbeam 71 can be fixed to the top sides of the flotation cell to facilitate the installation and connection of the rotating shaft and the flotation scraper device. The fixing column 72 is fixedly connected to the lower middle end of the crossbeam 71. The lower end of the fixing column 72 is fixedly connected to the outer ring of the connecting bearing 73, and the inner ring of the connecting bearing 73 is fixedly sleeved on the rotating shaft 5. The fixed end of the drive motor 4 is fixed above the crossbeam 71 by three diagonal braces. (Reference) Figure 8 , Figure 8The flotation cell 100 shown only shows the bottom of the cell, and the two ends of the crossbeam 71 are fixedly connected to the top of the side walls at both ends of the flotation cell 100.
