Description
Technical Field
[0001] This utility model relates to the technical field of slurry distribution devices, and more specifically, to a multi-channel slurry distribution box. Background Technology
[0002] In the mineral processing industry, whether it's non-ferrous metals, ferrous metals, or other non-metallic minerals, water is typically used as the medium for grinding, classifying, and separating ore. A single grinding and classifying system often corresponds to multiple separation devices, making it crucial to ensure the slurry is evenly distributed across all these devices. Therefore, various slurry distribution boxes are widely used. Furthermore, these distribution boxes are not limited to this stage; the need for slurry distribution may arise at various stages of the mineral processing flow.
[0003] In existing technologies, both the secondary and primary energy dissipation tanks of the slurry distribution box are cylindrical structures, with the primary energy dissipation tank nested within the middle of the secondary energy dissipation tank. A partition connects the bottom ends of the primary and secondary energy dissipation tanks, and overflow ports are provided along the annular sealing plate according to the number of ore distribution paths. The slurry falls vertically into the small central cylinder, and under the impact of the slurry, it overflows into the large cylinder, exiting through the ore discharge channel at the bottom of the large cylinder. In field use, the amount of slurry discharged from each overflow port is uneven, resulting in uneven and unstable feed rates to subsequent classification equipment, leading to low operating efficiency.
[0004] In summary, how to ensure uniform ore distribution in the ore distribution box and maintain consistent ore output from each ore outlet channel is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a multi-channel slurry distribution box, which effectively ensures uniform slurry distribution and guarantees consistent ore output from each ore outlet channel.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-channel slurry distribution box, comprising:
[0008] The first cylinder has a primary energy dissipation groove formed inside it, and multiple overflow ports with the same overflow height are opened on the side of the first cylinder.
[0009] The second cylinder has a secondary energy dissipation trough formed inside it. The first cylinder is located in the middle of the secondary energy dissipation trough. Multiple partition structures are provided between the first cylinder and the second cylinder to divide the second cylinder into multiple ore-dividing spaces. Each of the multiple ore-dividing spaces corresponds to a multiple overflow outlet.
[0010] The second cylinder is provided with a third cylinder in each of the ore-dividing spaces. The third cylinder has an outlet channel to allow the ore slurry in the ore-dividing space to be discharged.
[0011] The overflow height of the overflow port is higher than the bottom of the secondary energy dissipation tank, so as to form a first buffer space in the primary energy dissipation tank.
[0012] Preferably, a second buffer space is formed between the third cylinder and the first cylinder, and the ore discharge height of the ore discharge channel is higher than the overflow height of the overflow port.
[0013] Preferably, the height difference between the ore discharge height of the ore discharge channel and the overflow height of the overflow port is not less than 10 mm.
[0014] Preferably, the second cylinder has a mounting hole in the middle, the first cylinder is fixedly inserted into the mounting hole, and the bottom of the primary energy dissipation tank is lower than the bottom of the secondary energy dissipation tank.
[0015] Preferably, the bottom of the second cylinder is fixedly provided with a bottomless cylinder that is coaxial with the second cylinder and has the same aperture, so that the ore outlet channel is relatively lifted.
[0016] Preferably, the partition structure includes a plurality of partitions disposed between the first cylinder and the second cylinder, with two adjacent partitions located on both sides of the corresponding overflow port.
[0017] Preferably, the walls of the primary energy dissipation tank, the walls of the secondary energy dissipation tank, and the outer wall of the first cylinder located inside the second cylinder are all coated with a polyurethane layer, and the thickness of the polyurethane layer is not less than 10 mm.
[0018] Preferably, the outer wall of the second cylinder and the outer wall of the first cylinder located outside the second cylinder are both provided with a rust-proof layer.
[0019] Preferably, a flange is provided at the end of the third cylinder that is away from the ore-dividing space.
[0020] The multi-channel slurry distribution box provided by this utility model includes a first cylinder and a second cylinder. The first cylinder has a primary energy dissipation trough formed inside, and multiple overflow ports with the same overflow height are opened on the side of the first cylinder. The second cylinder has a secondary energy dissipation trough formed inside, and the first cylinder is located in the middle of the secondary energy dissipation trough. Multiple partition structures are provided between the first cylinder and the second cylinder to divide the second cylinder into multiple slurry distribution spaces. The multiple slurry distribution spaces correspond to the multiple overflow ports. A third cylinder is provided in each of the slurry distribution spaces in the second cylinder. The third cylinder has a slurry outlet channel to allow the slurry in the slurry distribution space to be discharged. The overflow height of the overflow port is higher than the bottom of the secondary energy dissipation trough to form a first buffer space in the primary energy dissipation trough.
[0021] The multi-channel slurry distribution box provided in this application allows upstream slurry to enter the first buffer space through the first cylinder and preferentially accumulate in the primary energy dissipation tank, avoiding uneven distribution caused by slurry flowing directly out through the overflow port. When the slurry in the first buffer space reaches the overflow port height, it is evenly transferred into the secondary energy dissipation tank through multiple overflow ports, achieving uniform distribution of the upstream slurry and ensuring consistent liquid levels within the multi-channel distribution space. The slurry in the distribution space flows out through the outlet channel, thus achieving slurry distribution. This application enables uniform slurry distribution in subsequent grading equipment, solving the problems of unreasonable slurry distribution box structure and difficulty in uniformly distributing slurry.

[0033] The core of this utility model is to provide a multi-channel slurry distribution box.
[0034] Please refer to Figures 1 to 3 .
[0035] The multi-channel slurry distribution box provided by this utility model includes a first cylinder 1 and a second cylinder 2. The first cylinder 1 has a primary energy dissipation tank 11 formed inside, and multiple overflow ports 12 with the same overflow height are opened on the side of the first cylinder 1. The second cylinder 2 has a secondary energy dissipation tank 21 formed inside, and the first cylinder 1 is located in the middle of the secondary energy dissipation tank 21. Multiple partition structures are provided between the first cylinder 1 and the second cylinder 2 to divide the second cylinder 2 into multiple ore distribution spaces 5. The multiple ore distribution spaces 5 correspond to the multiple overflow ports 12. The second cylinder 2 has a third cylinder 3 located in each ore distribution space 5. The third cylinder 3 has an outlet flow channel 31 to allow the slurry in the ore distribution space 5 to be discharged. The overflow height of the overflow port 12 is higher than the bottom of the secondary energy dissipation tank 21 to form a first buffer space 13 in the primary energy dissipation tank 11.
[0036] Specifically, the first cylinder 1 is located in the middle of the second cylinder 2. The first cylinder 1 contains a primary energy dissipation tank 11, and the second cylinder 2 contains a secondary energy dissipation tank 21. Multiple overflow ports 12 are circumferentially arranged in the first cylinder 1 inside the second cylinder 2. Multiple third cylinders 3 for ore separation are arranged around the position of the first cylinder 1 inside the second cylinder 2. Each third cylinder 3 has an outlet channel 31. The upstream slurry is separated in the following order: primary energy dissipation tank 11 → overflow port 12 → secondary energy dissipation tank 21 → outlet channel 31. The second cylinder 2 has multiple partition structures, dividing the secondary energy dissipation tank 21 into multiple ore separation spaces 5. Each ore separation space 5 corresponds to an overflow port 12, and each ore separation space 5 contains a third cylinder 3. The slurry flowing from the multiple overflow ports 12 flows evenly into the multiple ore separation spaces 5 and exits through the third cylinder 3 in each ore separation space 5 for ore separation. All the aforementioned overflow outlets 12 have the same overflow height, and the height of the overflow outlets 12 is higher than the tank body of the secondary energy dissipation tank 21, achieving secondary energy dissipation through the height difference. Furthermore, there is a certain height difference between the overflow outlets 12 and the bottom of the primary energy dissipation tank 11, forming a first buffer space 13. With the help of the first buffer space 13, effective energy dissipation is achieved after the upstream slurry enters the primary energy dissipation tank 11, and the upstream slurry is prevented from directly entering the secondary energy dissipation tank 21 through the overflow outlets 12, thus avoiding the problem of uneven slurry distribution. The height of the first buffer space 13 can be specifically set according to the actual situation.
[0037] In the aforementioned multi-channel slurry distribution box, upstream slurry enters the first buffer space 13 through the first cylinder 1 and preferentially accumulates in the primary energy dissipation tank 11. This avoids uneven slurry distribution caused by direct overflow from the overflow port. When the slurry in the first buffer space 13 reaches the height of the overflow port 12, it is evenly transferred into the secondary energy dissipation tank 11 through multiple overflow ports 12, achieving uniform slurry distribution and consistent liquid level within the multi-channel distribution space 5. The slurry in the distribution space 5 flows out through the outlet channel 31, thus achieving slurry distribution. This application enables uniform slurry distribution in subsequent grading equipment, solving the problems of unreasonable slurry distribution box structure and difficulty in uniformly distributing slurry.
[0038] The multi-channel slurry distribution box provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.
[0039] In one specific implementation, reference is made to... Figure 2 A second buffer space 32 is formed between the third cylinder 3 and the first cylinder 1, and the ore discharge height of the ore discharge channel 31 is higher than the overflow height of the overflow port 12.
[0040] Specifically, the upstream slurry flows into the second buffer space 32 of the secondary energy dissipation tank 21 through the overflow port 12. Since the ore discharge height of the ore discharge channel 31 is higher than the overflow height of the overflow port 12, the slurry flowing in will first accumulate in the second buffer space 32 and then flow out through the ore discharge channel 31 to distribute the ore, thereby making the amount of ore flowing out of each third cylinder 3 uniform.
[0041] Furthermore, the height difference between the ore discharge height of the ore discharge channel 31 and the overflow height of the overflow port 12 is not less than 10mm. This size can better ensure uniform ore discharge from the multiple ore discharge channels 31.
[0042] Based on any of the above embodiments, refer to Figure 2 The second cylinder 2 has an installation hole in the middle, and the first cylinder 1 is fixedly inserted into the installation hole. The bottom of the first energy dissipation tank 11 is lower than the bottom of the second energy dissipation tank 21.
[0043] Specifically, the first cylinder 1 is inserted into the mounting hole of the second cylinder 2, forming a partial placement in the second cylinder 2 and a partial placement inside the second cylinder 2, thereby achieving a height difference between the bottom of the first cylinder 1 and the second cylinder 2, and using this height difference and the overflow port 12 to form a first buffer space 13, which dissipates energy from the upstream slurry while uniformly distributing the ore.
[0044] Based on any of the above embodiments, refer to Figure 2 The bottom of the second cylinder 2 is fixedly provided with a bottomless cylinder that is coaxial with the second cylinder 2 and has the same aperture, so that the ore outlet channel 31 is relatively lifted.
[0045] Specifically, a bottomless cylinder with the same diameter and coaxiality is added to the bottom of the second cylinder 2. This bottomless cylinder can be made of wear-resistant material. The setting of the bottomless cylinder is equivalent to increasing the height of the bottom of the third cylinder 3 to a certain extent.
[0046] Based on any of the above embodiments, refer to Figure 2 The partition structure includes multiple partitions 4 disposed between the first cylinder 1 and the second cylinder 2, with two adjacent partitions 4 located on both sides of the corresponding overflow port 12.
[0047] Specifically, the baffle 4 is arranged vertically, and multiple baffles 4 are arranged circumferentially along the outer wall of the first cylinder 1, thereby dividing the secondary energy dissipation tank 21 into multiple ore-dividing spaces 5. Two adjacent baffles 4 are located on both sides of the corresponding overflow port 12, so as to prevent the slurry flowing out of the same overflow port from flowing into different ore-dividing spaces 5.
[0048] Based on any of the above embodiments, the walls of the primary energy dissipation tank 11, the walls of the secondary energy dissipation tank 21, and the outer wall of the first cylinder 1 located inside the second cylinder 2 are all coated with a polyurethane layer, and the thickness of the polyurethane layer is not less than 10mm.
[0049] Specifically, the polyurethane layer effectively enhances the wear resistance of the internal space of the sorting box, effectively resisting the erosion of high-speed, high-flow-rate media. This characteristic allows the polyurethane layer, when applied to the inner wall of the sorting box, to significantly extend the service life of the equipment and reduce maintenance and replacement costs caused by wear. Simultaneously, it effectively improves the corrosion resistance of the sorting box, effectively isolating it from corrosive media such as acids, alkalis, and salts, ensuring long-term stable operation of the equipment. When the polyurethane layer thickness is not less than 10mm, it can more effectively resist friction and wear, thereby extending the service life of the equipment.
[0050] Based on any of the above embodiments, the outer wall of the second cylinder 2 and the outer wall of the first cylinder 1 located outside the second cylinder 2 are both provided with an anti-rust layer.
[0051] Specifically, the application of an anti-rust layer can effectively extend the service life of the ore distribution box, improve equipment safety, reduce maintenance costs, enhance the equipment's aesthetics, and increase its adaptability.
[0052] Based on any of the above embodiments, a flange 6 is provided at the end of the third cylinder 3 that is away from the ore-dividing space 5.
[0053] Specifically, when receiving the separated slurry, the flange 6 allows for better connection between the third cylinder and the receiving pipe, thereby effectively improving the efficiency of subsequent operations after ore separation.
[0054] The multi-channel slurry separation method provided by this utility model is applied to any of the aforementioned multi-channel slurry separation boxes. The separation method includes:
[0055] The first cylinder 1 receives the upstream slurry, which undergoes primary energy dissipation via the first buffer space 13 within the first energy dissipation tank 11.
[0056] The slurry accumulates in the first buffer space 13 and flows evenly into each sub-mining space 5 after reaching the overflow height of the overflow port 12, where it undergoes secondary energy dissipation.
[0057] The slurry in the multiple ore-dividing spaces 5 flows out through their respective outlet channels 31 to separate the upstream slurry.
[0058] Specifically, this method primarily utilizes a multi-stage energy dissipation process to evenly distribute the upstream slurry into multiple ore-distributing spaces, which then flow out through their respective outlet channels, achieving effective ore separation. First, the upstream slurry is introduced into the first cylinder 1. After entering the first cylinder 1, the slurry first flows through the first buffer space 13 within the first energy dissipation tank 11. Within this first buffer space 13, the slurry's flow velocity and impact force are initially reduced, achieving primary energy dissipation. As the slurry continues to flow in, it gradually accumulates within the first buffer space 13. When the accumulated height of the slurry reaches the set overflow port 12, the slurry begins to flow evenly from the overflow port into each ore-distributing space 5. This process ensures that the slurry is evenly distributed into each ore-distributing space, laying the foundation for subsequent ore-distributing operations. After entering each ore-distributing space 5, the slurry undergoes further secondary energy dissipation. Within the slurry distribution space 5, the flow velocity and impact force of the slurry are further reduced, allowing the slurry to remain more stably within the space. Finally, the slurry, after secondary energy dissipation, flows out through its respective outlet channels 31. In this way, the upstream slurry is effectively distributed into multiple outlet channels 31, achieving the slurry distribution operation.
[0059] The above-described multi-channel slurry separation method, through this series of steps, can effectively and evenly distribute upstream slurry into multiple separation spaces, and ensure stable slurry outflow through a multi-stage energy dissipation process, thereby improving the efficiency and accuracy of slurry separation.
[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0061] The above provides a detailed description of a multi-channel slurry distribution box provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
