Description

Technical Field

[0001] This utility model relates to the technical field of desliming tanks for antimony flotation tailings, and more specifically, to a feed diversion device for desliming tanks for antimony flotation tailings. Background Technology

[0002] In the field of antimony flotation tailings desliming technology, efficient tailings treatment has always been a key research focus. With increasingly stringent environmental regulations and greater emphasis on comprehensive resource utilization, optimizing tailings treatment processes and improving desliming efficiency and quality have become urgent issues to be addressed. In the tailings treatment process, uniform feed distribution is one of the key factors to ensure the stable and efficient operation of the desliming tank. Existing feed distribution devices have revealed several shortcomings when dealing with materials with unique characteristics, such as antimony flotation tailings. For example, some devices fail to achieve uniform distribution, resulting in significant differences in feed rates across different parts of the desliming tank, thus affecting the consistency of desliming performance. Furthermore, some devices are prone to damage from tailings erosion and corrosion during long-term use, requiring frequent maintenance and component replacement, increasing production costs and downtime. Prior art document CN204841907U discloses an automatic rectification flotation feed desliming device, primarily designed for pretreatment of flotation feed in coal preparation plants. It pre-deslims the flotation feed by employing an inclined tube bundle rectification mechanism and an automatic buoyancy adjustment method for elastic suspension. However, this device is not suitable for the diversion requirements of antimony ore tailings desliming tanks. Antimony ore tailings differ significantly from coal slime in properties; the particle characteristics, chemical composition, and flow characteristics during diversion are all different. Furthermore, the device structure and working principle in this prior art document mainly focus on the desliming treatment of coal slime, failing to address the challenges faced when feeding antimony ore tailings into desliming tanks, such as how to adapt to the special properties of antimony ore tailings to achieve uniform diversion, and how to improve the device's wear resistance and corrosion resistance to cope with long-term tailings erosion and chemical attack. Therefore, developing a highly efficient diversion device specifically designed for feeding antimony ore tailings into desliming tanks is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a feed diversion device for a desliming tank of antimony flotation tailings, so as to solve the problem that the feed diversion device mentioned in the background art cannot achieve uniform diversion, resulting in large differences in the feed amount of different parts of the desliming tank, which in turn affects the consistency of the desliming effect.

[0004] To achieve the above objectives, this utility model provides a diversion device for feeding a desliming tank of antimony flotation tailings, including a diversion chamber. A feed pipe is connected to the top of the diversion chamber, and several diversion pipes are radially connected to the side of the diversion chamber. A support frame is installed at the bottom of the diversion chamber, and a spiral guide plate is installed in the middle of the interior of the diversion chamber. A feed inlet is provided at the top of the diversion chamber, and several discharge outlets are provided on the bottom side wall of the diversion chamber. The discharge outlets are connected to the diversion pipes.

[0005] This design is part of the core architecture of the device. It utilizes a combination of a "diversion bin + feed pipe + diversion pipe + support frame + spiral guide plate" to construct the basic process for tailings diversion: the tailings are first transported through the feed pipe to the inlet at the top of the diversion bin. After entering the bin, the spiral guide plate in the middle guides the flow direction of the material, preventing direct impact on the bottom of the bin. Finally, the tailings exit through the outlet on the bottom side wall of the diversion bin and precisely enter several radially connected diversion pipes, achieving the diversion logic of "centralized feeding → bin guidance → dispersed discharge." Simultaneously, the support frame at the bottom provides stable support for the diversion bin, ensuring that the overall structure does not shift under material impact.

[0006] Preferably, a fixing rod is vertically installed in the middle of the interior of the diversion chamber, and the outer side of the fixing rod is connected and fixed to the spiral guide plate.

[0007] This design directly connects and fixes the spiral guide plate to the outside of the fixed rod, forming an integrated "rod-plate" structure: the fixed rod runs vertically through the top and bottom of the diversion compartment, providing radial support and axial fixation for the spiral guide plate, ensuring that the spiral trajectory of the guide plate remains stable.

[0008] Preferably, a sleeve is fitted around the spiral guide plate, and a gap is left between the bottom of the sleeve and the bottom inner wall of the diversion chamber.

[0009] This feature involves installing a sleeve around the spiral guide plate with a bottom gap. Essentially, it creates a "dual flow channel": the sleeve divides the interior of the diversion chamber into an "inner layer" and an "outer layer." After the tailings enter the chamber, they are guided downwards by the spiral guide plate. Due to the obstruction of the sleeve, they cannot enter the interior of the sleeve and can only flow towards the discharge port along the path of "outer wall of the sleeve → bottom gap → inner wall of the diversion chamber." At the same time, the bottom gap prevents the sleeve from completely fitting against the bottom of the chamber, thus preventing the material from accumulating in the dead zone at the bottom of the chamber.

[0010] Preferably, the gap between the bottom of the sleeve and the bottom inner wall of the diversion chamber is 5-10 cm.

[0011] This setting limits the gap between the bottom of the sleeve and the inner wall of the bottom of the diversion chamber to 5-10cm, based on the particle size distribution characteristics of antimony tailings: 5cm is the "minimum effective gap", which can ensure that coarse particles can pass through smoothly and avoid coarse particles getting stuck due to the gap being too small; 10cm is the "maximum reasonable gap", which can prevent the material from having "local flow rate too fast or local flow rate too slow" when the gap is too large, thus maintaining the stability of material flow.

[0012] Preferably, a support block is installed at the top center of the support frame, which supports and positions the bottom of the diversion compartment.

[0013] This feature involves installing a support block at the top center of the support frame, which directly supports the bottom of the diversion chamber, forming a dual fixing structure of "top support + bottom positioning": the support frame provides upward tension and lateral stabilizing force from the top of the diversion chamber, while the support block provides upward support force from the bottom. The two work together to offset the downward pressure caused by the weight of the diversion chamber itself and the tailings, while limiting the vertical displacement and horizontal sway of the diversion chamber.

[0014] Preferably, the sidewall of the diversion pipe is divided into three layers: an outer layer, a middle layer, and an inner layer.

[0015] This design incorporates a three-layer composite structure of "outer layer + middle layer + inner layer" for the sidewall of the diversion pipe. Essentially, it is a "functional layered design": addressing the three major problems faced by diversion pipes in antimony tailings treatment—"external deformation, internal wear, and material corrosion"—the different layers perform different functions, avoiding the limitation of a single material not being able to meet multiple requirements simultaneously, and achieving a synergistic protection effect of "1+1+1>3".

[0016] Preferably, the outer layer is 5mm thick and made of high-strength Q345 steel, the middle layer is 3mm thick and made of wear-resistant rubber, and the inner layer is 2mm thick and made of corrosion-resistant 316L stainless steel.

[0017] This setting, for the aforementioned three-layer structure, maximizes the functionality of each layer through a combination of "specific thickness + compatible materials": Outer layer: 5mm thick Q345 steel: Q345 steel has high tensile strength, and its 5mm thickness can withstand external stress caused by installation collisions and vibrations, preventing pipe deformation; Middle layer: 3mm thick abrasion-resistant rubber: The abrasion-resistant rubber has a Shore hardness of ≥60 and a thickness of 3mm, allowing it to directly contact the tailings, buffering the scouring force of the particles and reducing wear on the inner wall; Inner layer: 2mm thick 316L stainless steel: 316L stainless steel contains molybdenum, which has excellent corrosion resistance to sulfides and acidic substances that may be contained in antimony ore tailings. The 2mm thickness can ensure the anti-corrosion effect while avoiding excessive weight of the pipeline.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: In this feed diversion device for the antimony ore tailings desliming tank, a spiral guide plate is installed in the middle of the diversion chamber and precisely fixed with a fixing rod. When the antimony ore tailings enter the diversion chamber from the feed inlet, the spiral guide plate guides the tailings to flow slowly downwards along a spiral trajectory. This avoids the problem in traditional devices where tailings directly accumulate in a certain area at the bottom of the diversion chamber due to gravity impact, leading to overfeeding at some outlets and underfeeding at others. Simultaneously, several diversion pipes radially connected to the side of the diversion chamber correspond one-to-one with the outlets on the bottom sidewall. The tailings, evenly distributed by the spiral guide plate, can smoothly enter the diversion pipes through each outlet, ultimately achieving uniform feeding into all areas of the desliming tank. This effectively ensures consistent processing conditions throughout the desliming tank, significantly improving the stability of the desliming effect and the overall desliming efficiency. To address the issues of uneven particle size and chemical content in antimony ore tailings that easily cause pipeline wear and corrosion, the device employs a three-layer composite structure design for the diversion pipe: the outer layer is made of 5mm thick Q345 steel, whose high strength and mechanical properties can withstand external installation impacts and structural deformation during long-term use, providing robust external protection for the diversion pipe; the middle layer is made of 3mm thick wear-resistant rubber, which directly buffers the scouring force of tailings flow on the inner wall of the pipe, significantly reducing the wear rate of tailings particles; the inner layer is made of 2mm thick 316L stainless steel, which has excellent chemical corrosion resistance and can effectively isolate the chemical substances in antimony ore tailings from eroding the inner wall of the pipe, preventing leakage or structural damage due to corrosion. This three-layer structure works synergistically, extending the service life compared to traditional single-material diversion pipes, reducing frequent maintenance and replacement due to pipeline wear and corrosion, and significantly lowering equipment maintenance costs and downtime losses. The device has a sleeve installed outside the spiral guide plate, and a gap of 5-10cm is left between the bottom of the sleeve and the inner wall of the bottom of the diversion chamber. This gap design can prevent tailings from accumulating at the bottom of the diversion chamber, and guide the tailings to flow to the discharge port along the channel between the outer wall of the sleeve and the inner wall of the diversion chamber, preventing tailings from forming a blockage between the spiral guide plate and the inner wall of the diversion chamber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a diversion device for feeding antimony flotation tailings desliming tank, such as... Figures 1-3 As shown, the system includes a diversion chamber 1, with a feed pipe 2 connected to the top of the diversion chamber 1. Several diversion pipes 3 are radially connected to the sides of the diversion chamber 1, and a support frame 4 is installed at the bottom of the diversion chamber 1. The support frame 4 is usually installed on the grid at the top of the desliming tank. A spiral guide plate 14 is installed in the middle of the interior of the diversion chamber 1. An inlet 11 is provided at the top of the diversion chamber 1, and several outlets 12 are provided on the bottom side wall of the diversion chamber 1. The outer side of the outlets 12 is connected to the diversion pipes 3.

[0022] The basic process of tailings diversion is constructed by combining "diversion bin 1 + feed pipe 2 + diversion pipe 3 + support frame 4 + spiral guide plate 14": the tailings are first transported to the feed inlet 11 at the top of the diversion bin 1 through the feed pipe 2. After entering the bin, the spiral guide plate 14 in the middle guides the flow direction of the material to avoid the material directly impacting the bottom of the bin. Finally, the tailings are precisely fed into several radially connected diversion pipes 3 through the discharge port 12 on the bottom side wall of the diversion bin 1, realizing the diversion logic of "centralized feeding → bin guidance → dispersed discharge". At the same time, the support frame 4 at the top provides stable support for the diversion bin 1 to ensure that the overall structure does not shift under the impact of the material.

[0023] A diversion framework adapted to antimony ore tailings flotation was established: In view of the characteristics of antimony ore tailings, such as "uneven particle size and easy accumulation", the spiral guide plate 14 intervenes in the material flow in advance to avoid the problem of "material rushing to the bottom of the bin and local accumulation" in traditional devices, and lays the foundation for subsequent uniform diversion. Achieving precise "one-to-one" diversion: The discharge port 12 corresponds one-to-one with the diversion pipe 3, ensuring that the tailings after guidance can directly enter the designated diversion pipe, avoiding cross-contamination and disorder of materials in the bin, and initially ensuring the stability of material supply at each feed point of the desliming tank. Ensuring the overall stability of the device: The support frame 4 offsets the stress caused by the impact of tailings and the weight of the device itself, prevents the feed / discharge misalignment caused by the displacement of the diversion chamber 1, and ensures that the diversion process is continuous and uninterrupted.

[0024] In this embodiment, a fixing rod 13 is vertically installed in the middle of the inside of the diversion chamber 1, and the outer side of the fixing rod 13 is connected and fixed to the spiral guide plate 14.

[0025] The spiral guide plate 14 is directly connected and fixed to the outside of the fixed rod to form an integrated "rod-plate" structure: the fixed rod 13 runs vertically through the upper and lower parts of the diversion compartment, providing radial support and axial fixation for the spiral guide plate 14, ensuring that the spiral trajectory of the guide plate is always stable.

[0026] Solving the "instability problem" of the spiral guide plate: Preventing the spiral guide plate 14 from deforming or shifting, such as tilting of the guide plate or deviation of the spiral trajectory, when antimony tailings are impacted at high speed, ensuring that the tailings always flow along the preset spiral path and maintaining the uniformity of diversion from the source; Extending the service life of the guide plate: The fixing rod 13 disperses the impact force of tailings on the guide plate, reduces cracking or wear caused by excessive local stress on the guide plate, and reduces the replacement frequency of core components.

[0027] Specifically, a sleeve 15 is fitted around the outside of the spiral guide plate 14, and a gap is left between the bottom of the sleeve 15 and the bottom inner wall of the diversion chamber 1.

[0028] A sleeve 15 is fitted over the spiral guide plate 14 with a bottom gap, which essentially creates a "dual flow channel": the sleeve 15 divides the interior of the diversion chamber 1 into the "inner sleeve interior" and the "between the outer sleeve outer wall and the inner wall of the diversion chamber". After the tailings enter the chamber, they are guided downward by the spiral guide plate 14. Due to the obstruction of the sleeve 15, they cannot enter the sleeve interior and can only flow to the discharge port 12 along the path of "outer sleeve wall → bottom gap → inner wall of diversion chamber". At the same time, the bottom gap prevents the sleeve from completely fitting with the bottom of the chamber, preventing the material from accumulating in the dead zone at the bottom of the chamber.

[0029] To avoid "blockage around the guide plate": coarse particles in antimony tailings are easily stuck in the gap between the spiral guide plate 14 and the inner wall of the diversion chamber. The sleeve 15 directly isolates the gap, allowing the material to flow only along the outer channel, thus eliminating the risk of blockage from a structural perspective. Optimize material flow path: Force materials to flow along the "ring outer channel" to avoid some materials directly impacting a certain area at the bottom of the silo, and further improve the consistency of the feed amount at each discharge port 12.

[0030] Furthermore, the gap between the bottom of the sleeve 15 and the bottom inner wall of the diversion chamber 1 is 5-10cm.

[0031] The gap between the bottom of sleeve 15 and the inner wall of the bottom of the diversion chamber 1 is limited to 5-10cm. This is based on the particle size distribution characteristics of antimony tailings: 5cm is the "minimum effective gap", which can ensure that coarse particles such as 1-2mm particles can pass through smoothly and avoid coarse particles from getting stuck due to too small a gap; 10cm is the "maximum reasonable gap", which can prevent the material from having "local flow velocity too fast or local flow velocity too slow" due to the excessively wide flow path when the gap is too large, thus maintaining the stability of material flow.

[0032] Achieve "precise flow control": Avoid flow diversion failures caused by improper gaps, ensure that antimony tailings of different particle sizes can pass through the gaps smoothly, and maintain a consistent feed rate at each outlet; Adapt to the characteristics of antimony tailings: Specifically solve the problem of "large particle size range" of antimony tailings, eliminating the need to adjust the gaps due to changes in tailings particle size, and improving the adaptability of the device to different operating conditions.

[0033] Furthermore, a support block 42 is installed at the top center of the support frame 4, which supports and positions the bottom of the diversion chamber 1.

[0034] A support block 42 is installed at the top middle of the support frame 4 and directly supports the bottom of the diversion chamber 1, forming a double fixing structure of "top support + bottom positioning": the support frame 4 provides upward tension and lateral stabilizing force from the top of the diversion chamber, and the support block 42 provides upward support force from the bottom. The two work together to offset the downward pressure brought by the weight of the diversion chamber 1 itself and the weight of the tailings, while limiting the vertical displacement and horizontal sway of the diversion chamber.

[0035] To prevent the diversion bin 1 from sinking or tilting due to the dynamic changes in the weight of the material in the tailings feed bin, ensure that the discharge port 12 and the diversion pipe 3 are always precisely connected to prevent material leakage.

[0036] Furthermore, the sidewall of the diversion pipe 3 is divided into three layers: outer layer 31, middle layer 32, and inner layer 33.

[0037] The sidewall of the diversion pipe is designed as a three-layer composite structure of "outer layer 31 + middle layer 32 + inner layer 33". Essentially, it is a "functional layered design". In response to the three major problems faced by the diversion pipe in antimony tailings treatment, namely "external deformation, internal wear and tear, and material corrosion", the different layers undertake different functions, avoiding the defect that a single material cannot meet multiple needs at the same time, and achieving a synergistic protection effect of "1+1+1>3".

[0038] Provide a "comprehensive protection framework" for the diversion pipe: clearly define the functional positioning of each layer, lay the foundation for subsequent selection of specific materials, ensure that the diversion pipe can not only resist external impacts, withstand internal tailings erosion, and isolate chemical corrosion, and adapt to the complex working conditions of antimony flotation tailings; extend the service life of the core components of the diversion pipe: compared with traditional single-material diversion pipes, the layered structure can address different failure problems in a targeted manner, avoid the scrapping of the entire pipeline due to a single defect, and reduce maintenance costs.

[0039] Furthermore, the outer layer 31 is 5mm thick and made of high-strength Q345 steel, the middle layer 32 is 3mm thick and made of wear-resistant rubber, and the inner layer 33 is 2mm thick and made of corrosion-resistant 316L stainless steel.

[0040] For the aforementioned three-layer structure, the function of each layer is maximized through a combination of "specific thickness + suitable materials": Outer layer 31: 5mm thick Q345 steel: Q345 steel has a high tensile strength of ≥345MPa, and its 5mm thickness can withstand external stress from installation collisions and vibrations, preventing pipe deformation; Middle layer 32: 3mm thick wear-resistant rubber: Wear-resistant rubber has a Shore hardness of ≥60, and its 3mm thickness allows direct contact with tailings, buffering the scouring force of particles and reducing inner wall wear; Inner layer 33: 2mm thick 316L stainless steel: 316L stainless steel contains molybdenum, exhibiting excellent corrosion resistance to sulfides and acidic substances that may be present in antimony ore tailings, and its 2mm thickness ensures corrosion protection while preventing excessive pipe weight. The functions of each layer are precisely implemented: the outer layer addresses the "deformation resistance" issue, ensuring the integrity of the pipe structure; the middle layer addresses the "wear resistance" issue; and the inner layer addresses the "corrosion resistance" issue, preventing leaks due to chemical corrosion. Significantly improves the cost-effectiveness of the shunt tube: the thickness of the three-layer material matches its functional requirements, controlling costs while ensuring performance.

[0041] When in use, the feed diversion device for the desliming tank of antimony ore flotation uses a dual guiding mechanism consisting of a spiral guide plate and a sleeve. The spiral guide plate 14 forms a stable spiral trajectory with the support of the fixed rod 13, changing the tailings from "vertical straight rush" to "spiral slow descent," thus avoiding local accumulation caused by material impacting the bottom of the tank. The outer sleeve 15 further divides the interior of the diversion tank 1 into an "ineffective inner layer" and an "effective outer layer channel," forcing the tailings to flow along the annular path between the outer wall of the sleeve and the inner wall of the diversion tank, ensuring that the material evenly covers all discharge ports 12, thus guaranteeing the uniformity of the diversion from the source. Dual control of flow rate and velocity is achieved through "gap limitation" - the 5-10cm gap at the bottom of sleeve 15 is based on the particle size distribution design of antimony tailings, which ensures that coarse particles pass through smoothly while avoiding flow velocity differences caused by excessively wide gaps. The device is guaranteed to operate for a long time by using "double support + three-layer pipeline" - the support frame 4 and the support block 42 form a fixed structure of "top pull + bottom support" to offset the stress caused by the weight of tailings and vibration impact, and prevent the diversion chamber 1 from shifting; the three-layer composite structure of the diversion pipe 3 is specifically designed to resist external impact, internal wear and chemical corrosion, extend the service life of components and avoid diversion interruption due to pipeline damage.

[0042] Based on the flow sequence of tailings from entering the device to being transported to the desludge tank, the overall working process is divided into 5 key steps, each corresponding to a specific structural function, as detailed below: Step 1: Tailings entry and initial guidance After flotation, the antimony tailings enter the feed pipe 2 through the conveying system and are injected into the diversion bin 1 through the feed inlet 11 at the top of the diversion bin. At this time, the spiral guide plate 14 in the middle of the diversion bin is fixed by the fixing rod 13 and immediately takes effect without the risk of deviation, guiding the vertically falling tailings onto the spiral trajectory, so that the material flows slowly downward along the guide plate, avoiding the problem of "tailings rushing straight to the bottom of the bin and local accumulation" in traditional devices, and laying the foundation for subsequent uniform diversion. Step 2: Annular channel constraint and gap flow control When the tailings flow downwards along the spiral guide plate 14, they are blocked by the outer sleeve 15 and cannot enter the ineffective area inside the sleeve. They can only turn to the annular outer channel between the outer wall of the sleeve and the inner wall of the diversion chamber. When the material flows to the bottom of the diversion chamber, it enters the bottom area of ​​the chamber through the 5-10cm gap between the sleeve 15 and the inner wall of the chamber bottom. This gap is precisely adapted to the size of the tailings particles, allowing coarse particles of 1-2mm to pass through smoothly. At the same time, it avoids the problem of "fast flow near the gap and slow flow far from the gap" caused by an excessively wide gap, ensuring that the tailings are evenly distributed around all the discharge ports 12 on the bottom side wall of the diversion chamber. Step 3: Diverting water supply through the branch pipe The tailings distributed at each discharge port 12 are connected one-to-one by the "discharge port-diversion pipe" and enter several radially distributed diversion pipes 3 to uniformly transport the tailings to each area of ​​the desliming tank. Step 4: Stabilize the device During the tailings flow process, the support frame 4 and the support block 42 work together to stabilize the system: the support frame 4 provides lateral stabilizing force and upward pulling force from the top of the diversion chamber 1 to counteract the horizontal swaying caused by the tailings impact; the support block 42 directly supports the bottom of the diversion chamber, bearing the downward pressure brought by the weight of the device and the weight of the tailings, preventing the diversion chamber from sinking or tilting, and ensuring that the discharge port 12 and the diversion pipe 3 are always accurately connected, with no risk of material leakage. Step 5: Long-term protection and continuous operation The three-layer structure of the diversion pipe 3 provides continuous protection throughout the entire operation: the outer 5mm thick Q345 steel layer resists installation collisions and vibration impacts, preventing pipe deformation; the middle 3mm thick wear-resistant rubber layer directly contacts the flowing tailings, buffering the scouring force of particles and reducing the wear rate of the inner wall; the inner 2mm thick 316L stainless steel layer isolates the pipe from the corrosion of sulfides and acidic substances in the tailings, preventing material leakage. The synergistic effect of these three layers allows the device to operate continuously for extended periods, reducing the frequency of downtime maintenance due to component damage.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
