A grinding and grading system often corresponds to multiple sorting equipment. At this time, how to evenly distribute the slurry to each device is very important. Therefore, various slurry separation boxes are widely used. In addition, the separation box is not limited to this link. There may be a need for separation in each link of the mineral processing process.

[0003] In the current existing technology, the secondary energy dissipation trough and the primary energy dissipation trough of the slurry separation box are both cylindrical structures, and the primary energy dissipation trough is mounted in the middle of the inner cavity of the secondary energy dissipation trough. A partition is connected between the bottom end of the primary energy dissipation trough and the bottom end of the secondary energy dissipation trough, and corresponding overflow ports are provided at the upper ring of the annular sealing plate according to the number of separation routes. The slurry falls vertically into the small cylinder in the middle, and under the impact of the slurry, it flips into the large cylinder from the overflow port and is discharged through the ore outlet channel at the bottom of the large cylinder. During on-site use, the amount of slurry discharged from each overflow port is uneven, resulting in uneven and unstable ore feeding of subsequent grading equipment, and low operating efficiency.

[0038] The core of the present invention is to provide a multi-path slurry separation box.

[0039] Another core of the present invention is to provide a multi-path slurry separation method, which adopts the multi-path slurry separation box.

[0040] Please refer to Figures 1 to 3 .

[0041] The multi-path slurry dividing box provided by the present invention comprises a first cylinder body 1 and a second cylinder body 2, a primary energy dissipation groove 11 is formed in the first cylinder body 1, a plurality of overflow ports 12 with the same overflow height are provided on the side of the first cylinder body 1, a secondary energy dissipation groove 21 is formed in the second cylinder body 2, the first cylinder body 1 is arranged in the middle part of the secondary energy dissipation groove 21, a plurality of partition structures are arranged between the first cylinder body 1 and the second cylinder body 2, so that a plurality of dividing spaces 5 are separated in the second cylinder body 2, and the plurality of dividing spaces 5 respectively correspond to the plurality of overflow ports 12, the second cylinder body 2 is provided with a third cylinder body 3 in each dividing space 5, the third cylinder body 3 is provided with an ore discharge channel 31, so that the slurry in the ore discharge space 5 can be discharged, the overflow height of the overflow port 12 is higher than the bottom of the secondary energy dissipation groove 21, so as to form a first buffer space 13 in the primary energy dissipation groove 11.

[0042] Specifically, the first cylinder 1 is arranged in the middle of the second cylinder 2, wherein the first cylinder 1 contains a primary energy dissipation groove 11, the second cylinder 2 contains a secondary energy dissipation groove 21, the first cylinder 1 is provided with a plurality of overflow ports 12 in the circumferential direction inside the second cylinder 2, a plurality of third cylinders 3 for ore separation are arranged around the first cylinder 1 in the second cylinder 2, each third cylinder 3 is provided with an ore discharge channel 31, and the upstream slurry is separated in the order of primary energy dissipation groove 11 → overflow port 12 → secondary energy dissipation groove 21 → ore discharge channel 31. A plurality of partition structures are arranged in the second cylinder 2, thereby dividing the secondary energy dissipation groove 21 into a plurality of ore separation spaces 5, each ore separation space 5 corresponds to an overflow port 12, and a third cylinder 3 is arranged in each ore separation space 5, the slurry flowing out of the plurality of overflow ports 12 flows evenly into the plurality of ore separation spaces 5, and flows out through the third cylinder 3 in each ore separation space 5 for ore separation. The above-mentioned multiple overflow ports 12 are all of the same overflow height, and the height of the overflow port 12 is higher than the tank body of the secondary energy dissipation tank 21, and the secondary energy dissipation is achieved through the height difference. There is also a certain height difference between the overflow port 12 and the bottom of the primary energy dissipation tank 11, and the first buffer space 13 is formed by utilizing the height difference. With the help of the first buffer space 13, after the upstream slurry enters the primary energy dissipation tank 11, effective energy dissipation is achieved, and the upstream slurry is prevented from directly entering the secondary energy dissipation tank 21 through the overflow port 12, thereby avoiding the problem of uneven slurry distribution. The height of the first buffer space 13 can be specifically set according to actual conditions.

[0043] In the above-mentioned multi-path slurry separation box, the upstream slurry enters the first buffer space 13 through the first cylinder 1 and is preferentially accumulated in the first energy dissipation trough 11, so as to avoid the problem of uneven separation caused by the slurry flowing out directly through the overflow port. When the slurry in the first buffer space 13 reaches the height of the overflow port 12, the slurry is evenly turned into the second energy dissipation trough 11 through multiple overflow ports 12, so as to achieve uniform separation of the upstream slurry and achieve the purpose of consistent liquid level in the multi-path separation space 5. The slurry in the separation space 5 flows out through the outlet channel 31 to achieve separation. The present application realizes uniform separation of subsequent grading equipment and solves the problems of unreasonable structure of the slurry separation box and difficulty in uniformly distributing the slurry.

[0044] The multi-path slurry separation box provided by the present invention is introduced in more detail below with reference to the accompanying drawings and specific embodiments.

[0045] In a specific embodiment, reference 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 .

[0046] Specifically, the upstream slurry flows into the second buffer space 32 of the secondary energy dissipation trough 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 inflowing slurry will first accumulate in the second buffer space 32, and then flow out through the ore discharge channel 31 to separate the ore, so that the amount of ore flowing out of each third cylinder 3 is uniform.

[0047] 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 10 mm. This size can better ensure uniform ore discharge from the multiple ore discharge channels 31 .

[0048] Based on any of the above embodiments, Figure 2 A mounting hole is opened in the middle of the second cylinder 2, and the first cylinder 1 is fixedly inserted in the mounting hole. The bottom of the first energy dissipation groove 11 is lower than the bottom of the second energy dissipation groove 21.

[0049] Specifically, the first cylinder 1 is inserted into the mounting hole of the second cylinder 2, so that part of it is placed in the second cylinder 2 and part of it is placed in the second cylinder 2, thereby realizing the height difference between the bottom of the first cylinder 1 and the bottom of the second cylinder 2, and forming a first buffer space 13 by means of the height difference and the overflow port 12, so as to evenly separate the ore while dissipating energy of the upstream slurry.

[0050] Based on any of the above embodiments, Figure 2 A bottomless cylinder having the same axis and the same aperture as the second cylinder 2 is fixedly arranged at the bottom of the second cylinder 2 so that the ore outlet channel 31 is relatively lifted.

[0051] Specifically, a bottomless cylinder with the same aperture and axis is added to the bottom of the second cylinder 2. The bottomless cylinder can be made of wear-resistant material. The setting of the bottomless cylinder is equivalent to raising the height of the bottom of the third cylinder 3 to a certain extent.

[0052] Based on any of the above embodiments, Figure 2 The partition structure includes a plurality of partitions 4 disposed between the first cylinder 1 and the second cylinder 2 , and two adjacent partitions 4 are located on both sides of the corresponding overflow port 12 .

[0053] Specifically, the partition 4 is vertically arranged, and multiple partitions 4 are arranged circumferentially along the outer wall of the first cylinder 1, so as to divide the secondary energy dissipation trough 21 into multiple mineral separation spaces 5. Two adjacent partitions 4 are respectively located on both sides of the corresponding overflow port 12 to prevent the slurry flowing out of the same overflow port from flowing into different mineral separation spaces 5.

[0054] Based on any of the above embodiments, the groove wall of the first energy dissipation groove 11, the groove wall of the second energy dissipation groove 21 and the outer wall of the first cylinder 1 located inside the second cylinder 2 are sprayed with a polyurethane layer, and the thickness of the polyurethane layer is not less than 10 mm.

[0055] Specifically, the polyurethane layer can effectively improve the wear resistance of the internal space of the ore separation box, and can effectively resist the erosion of high-speed and high-flow media. This feature enables the polyurethane layer to significantly extend the service life of the equipment when used on the inner wall of the ore separation box, and reduce the maintenance and replacement costs caused by wear. At the same time, it can effectively improve the corrosion resistance of the ore separation box, and can effectively isolate the corrosion of corrosive media such as acids, alkalis, and salts on the box body, ensuring the long-term stable operation of the equipment. When the thickness of the polyurethane layer is not less than 10mm, it can more effectively resist friction and wear, thereby extending the service life of the equipment.

[0056] On the basis of any one 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.

[0057] Specifically, the setting of the anti-rust layer can effectively increase the service life of the ore separation box, improve equipment safety, reduce maintenance costs, improve equipment aesthetics and enhance equipment adaptability.

[0058] On the basis of any one of the above embodiments, a flange 6 is provided at one end of the third cylinder 3 away from the mineral distribution space 5 .

[0059] Specifically, when receiving the separated slurry, the arrangement of the flange 6 can better enable the third cylinder to be connected to the receiving pipe, thereby effectively improving the subsequent operation efficiency of the separation.

[0060] The multi-channel ore slurry separation method provided by the present invention is applied to any of the multi-channel ore slurry separation boxes mentioned above, and the separation method includes:

[0061] The upstream slurry is received by the first cylinder 1, and the upstream slurry is subjected to primary energy dissipation through the first buffer space 13 in the first energy dissipation groove 11;

[0062] The slurry accumulates in the first buffer space 13, and after reaching the overflow height of the overflow port 12, it flows evenly into each ore separation space 5 and dissipates energy in the second stage;

[0063] The ore pulp in the plurality of separation spaces 5 flows out through respective ore outlet channels 31 to separate the upstream ore pulp.

[0064] Specifically, the method mainly distributes the upstream slurry evenly to multiple ore distribution spaces through a multi-stage energy dissipation process, and then flows out through respective ore outlet channels to achieve effective ore distribution of the slurry. First, the upstream slurry is introduced into the first cylinder 1. After entering the first cylinder 1, the slurry will first flow through the first buffer space 13 in the first energy dissipation groove 11. In this first buffer space 13, the flow rate and impact force of the slurry will be initially reduced, that is, the first-level energy dissipation is achieved. With the continuous inflow of the slurry, the slurry will gradually accumulate in the first buffer space 13. When the accumulation height of the slurry reaches the set height of the overflow port 12, the slurry will begin to flow evenly from the overflow port into each ore distribution space 5. This process ensures that the slurry can be evenly distributed to each ore distribution space, laying the foundation for subsequent ore distribution operations. After entering each ore distribution space 5, the slurry will further undergo secondary energy dissipation. In the separation space 5, the flow rate and impact force of the slurry will be further reduced, so that the slurry will stay in the separation space more stably. Finally, after the secondary energy dissipation, the slurry will flow out through the corresponding ore outlet channels 31. In this way, the upstream slurry is effectively distributed to multiple ore outlet channels 31, realizing the slurry separation operation.

[0065] The above-mentioned multi-path slurry separation method, through this series of steps, the multi-path slurry separation method provided by the present invention can effectively and evenly distribute the upstream slurry to multiple separation spaces, and ensure the stable outflow of the slurry through a multi-stage energy dissipation process, thereby improving the efficiency and accuracy of separation.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0067] The above is a detailed introduction to a multi-path slurry separation box and a separation method provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the present invention.
