Description

Technical Field

[0001] This invention relates to the field of mineral processing technology, and in particular to an open-type trough-type slurry distribution device. Background Technology

[0002] In mineral processing operations, slurry distribution is crucial for scenarios or concentrators with large processing volumes. During the slurry distribution process, one slurry needs to be divided into several slurries. Uniform distribution affects the subsequent processes and product differentiation.

[0003] Traditional slurry distribution methods often use slurry distribution valves. However, these valves suffer from problems such as leakage due to incomplete closure, inability to clean the filter on time, poor filter plate cleaning, and reduced filter lifespan. Furthermore, the use of straight-through pipes or concealed channels in operation easily leads to outlet blockage, hindering uniform slurry discharge and reducing subsequent efficiency. Therefore, existing technologies suffer from problems such as slurry distribution prone to blockage, difficult equipment cleaning, and high maintenance costs. Summary of the Invention

[0004] To address the problems of easy clogging, difficult equipment cleaning, and high maintenance costs in existing slurry distribution technologies, the applicant provides a structurally sound open-type trough-type slurry distribution device. This device achieves excellent uniformity of slurry composition, avoiding uneven distribution and facilitating consistent processing results across different subsequent equipment. Furthermore, it is easier to operate and implement, offering significant convenience for maintenance and operation.

[0005] The technical solution adopted in this invention is as follows: An open-type trough-type slurry distribution device includes a box body formed by a front plate, a rear plate, a left plate, a right plate, and a bottom plate. The top of the box body is open. Inside the box body, from front to back, there are slurry inlet troughs, slurry storage troughs, slurry distribution troughs, and slurry outlet troughs arranged at intervals. The slurry inlet trough is formed between the slurry inlet baffle and the front plate. Several overflow ports are opened at the top of the slurry inlet baffle. The slurry storage trough is formed between the slurry storage baffle and the slurry inlet trough. Foam baffles are located inside the slurry storage trough and are spaced between the slurry inlet baffle and the slurry storage baffle. A horizontally arranged platform is provided at the top of the slurry storage baffle and its rear end is fixedly connected to a vertically arranged distribution baffle. A distribution chamber is formed above the platform. Several spaced circular through holes are opened on the surface of the platform. Each circular through hole is connected to a vertically arranged distribution cylinder. A filter screen is installed at each circular through hole on the platform. Several vertically arranged partitions are provided on the rear side of the platform. The partitions are arranged along the front-rear direction of the box body. The partitions divide the interior of the box body on the rear side of the platform into several parallel grid spaces. Each grid space is arranged opposite to the circular through holes on the platform. The flow-limiting partition and the slurry storage partition form the slurry distribution trough. The height of the flow-limiting partition is lower than that of the platform. A slurry outlet pipe is provided on the bottom plate of the box at the bottom of each slurry outlet trough.

[0006] As a further improvement to the above technical solution: The foam baffle is a gate-shaped panel, consisting of an upper horizontal panel and two lower vertical panels. The two vertical panels are vertically connected to the horizontal panel to form a whole, and there is a through channel between the two vertical panels. The two vertical panels and the upper horizontal panel form a gate-shaped structure.

[0007] The distribution cylinder is suspended above the bottom plate of the box, and connects the distribution room and the space under the platform to form a cylindrical channel.

[0008] The slurry outlet troughs are located in each grid space, and the slurry outlet pipes are vertically arranged, connecting the inside of the slurry outlet troughs to the outside of the box body.

[0009] The overflow port on the slurry inlet baffle is a rectangular opening, and a guide plate is installed at the bottom of the overflow port opening.

[0010] The guide plate includes an installation part and an inclined plate part that are connected together. The installation part adopts a structure with a U-shaped bayonet for installation and connection with the overflow port of the slurry inlet baffle. The inclined plate part adopts a downward inclined plate structure.

[0011] A grouting pipe is installed on one side of the grouting trough of the box body. The grouting pipe is parallel to the front plate of the box body. The slurry from the grouting pipe flows into the grouting trough from one end. At this time, the overflow port of the grouting baffle is set on the part of the grouting baffle away from the grouting pipe. A first wear-resistant plate is placed at the bottom of the grouting trough of the box body. The first wear-resistant plate covers the bottom area of ​​the grouting trough.

[0012] A second wear-resistant plate is placed at the bottom of the slurry tank of the box body, and the second wear-resistant plate covers the bottom area of ​​the slurry tank.

[0013] The slurry inlet baffle and the front panel of the tank are arranged parallel to each other at intervals, and the two ends of the slurry inlet baffle are fixed to the inner walls of the left and right panels of the tank, and the bottom of the slurry inlet baffle is fixed to the bottom panel of the tank; the two ends of the foam baffle are fixed to the inner walls of the left and right panels of the tank, and the bottom of the foam baffle is fixed to the bottom panel of the tank; the two ends of the slurry storage baffle are fixed to the inner walls of the left and right panels of the tank, and the bottom of the slurry storage baffle is fixed to the bottom panel of the tank; the two ends of the flow-limiting baffle are fixed to the inner wall of the slurry storage tank, and the bottom of the flow-limiting baffle is fixed to the bottom panel of the tank.

[0014] The foam baffle and the slurry inlet baffle are set in parallel and spaced apart, the slurry storage baffle and the slurry inlet baffle are set in parallel and spaced apart, and the partition baffle and the platform are set perpendicular to each other.

[0015] The beneficial effects of this invention are as follows: This invention employs an open-top design for the container, with no internal connecting pipes or concealed passages, allowing direct observation and inspection of every part. Furthermore, the container structure is easier to operate and implement, providing significant convenience for maintenance and operation. The container utilizes overflow mechanisms in multiple locations to flow and distribute the slurry, effectively homogenizing its composition and preventing uneven distribution. This facilitates consistent processing results across different subsequent equipment. This design is crucial for high-volume mineral processing scenarios or concentrators, as uniform slurry distribution impacts the consistency of subsequent processes and products.

[0016] This invention employs foam baffles to block foam in the slurry, significantly reducing foam in subsequent flotation processes. This solves the problem of excessive foam in the slurry hindering subsequent mineral processing and improves overall process efficiency. Because this invention uses an open-top design, with each tank having an open structure, it allows for the placement and replacement of the first wear-resistant plate in the feed tank and the placement and replacement of the second wear-resistant plate in the distribution tank. This is a key technical advantage gained from the structure of this invention.

[0017] This invention features a filter screen installed at each circular through-hole in the platform. The filter screens filtration the flowing slurry, separating the ore and controlling its particle size, filtering out undesirable impurities and improving slurry quality. Furthermore, the filtration operation is completed automatically during the overflow process, rather than being a separate procedure, saving steps and time. Attached Figure Description

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figures 1 to 6As shown, the open-type trough-type slurry distribution device of the present invention includes a box body formed by a front plate 1, a rear plate 2, a left plate 3, a right plate 4, and a bottom plate 5. The box body is preferably a cuboid structure with an open top. The front and rear sections of the box body are vertically arranged with the front plate 1 and the rear plate 2, the left and right sections are vertically arranged with the left plate 3 and the right plate 4, and the bottom of the box body is a horizontally arranged bottom plate 5. The bottom plate 5 is vertically connected to the front plate 1, the rear plate 2, the left plate 3, and the right plate 4 to form a closed chamber. The box body of the present invention features an open-top design, with no internal connecting pipes or hidden passages, allowing direct observation and inspection of each part. Furthermore, the box structure is easier to operate and implement, providing significant convenience for maintenance and operation.

[0027] Inside the tank, from front to back, are arranged a slurry inlet trough 6, a slurry storage trough 7, a slurry distribution trough 9, and a slurry outlet trough 10 at intervals. A vertically installed slurry inlet baffle 11 is provided inside the tank, parallel to and spaced apart from the front plate 1. The two ends of the slurry inlet baffle 11 are fixed to the inner walls of the left plate 3 and right plate 4, and the bottom of the slurry inlet baffle 11 is fixed to the bottom plate 5. The slurry inlet trough 6 is formed between the slurry inlet baffle 11 and the front plate 1. Several overflow ports 11A are provided at the top of the slurry inlet baffle 11, allowing the slurry in the slurry inlet trough 6 to overflow into the storage trough 7. The multiple overflow methods used within the tank for slurry flow and distribution effectively homogenize the slurry composition, preventing uneven distribution and facilitating consistent processing results with different subsequent equipment. This setup is crucial for scenarios or concentrators with large mineral processing volumes, as uniform mineral distribution affects the differentiation of subsequent processes and products.

[0028] A vertically arranged foam baffle 12 is provided on the rear side of the slurry inlet baffle 11. The two ends of the foam baffle 12 are fixed to the inner walls of the left plate 3 and the right plate 4 of the tank, and the bottom of the foam baffle 12 is fixed to the bottom plate 5 of the tank. The foam baffle 12 is arranged parallel to and spaced apart from the slurry inlet baffle 11. Preferably, the foam baffle 12 is a U-shaped plate, which includes an upper horizontal plate 12A and two lower vertical plates 12B. The two vertical plates 12B are vertically connected to the horizontal plate 12A to form a whole, and there is a through channel between the two vertical plates 12B. The two vertical plates 12B and the upper horizontal plate 12A form a U-shaped structure.

[0029] A vertically arranged slurry storage baffle 13 is provided behind the foam baffle 12. The two ends of the slurry storage baffle 13 are fixed to the inner walls of the left plate 3 and the right plate 4 of the tank, and the bottom of the slurry storage baffle 13 is fixed to the bottom plate 5 of the tank. The slurry storage baffle 13 and the slurry inlet baffle 11 are arranged parallel to each other at intervals, and the slurry storage tank 7 is formed between the slurry storage baffle 13 and the slurry inlet baffle 11. The foam baffle 12 is located inside the slurry storage tank 7 and is spaced between the slurry inlet baffle 11 and the slurry storage baffle 13. Mineral slurry often contains a large amount of foam, which is detrimental to subsequent mineral processing operations. The foam baffle 12 serves to block the foam in the mineral slurry, significantly reducing foam in the subsequent flotation process and improving the overall process efficiency.

[0030] A horizontally positioned platform 14 is provided at the top and rear of the slurry storage baffle 13, with its rear end fixedly connected to a vertically positioned distribution baffle 15. A distribution chamber 8 is formed above the platform 14. Several spaced-apart circular through holes are provided on the surface of the platform 14, each circular through hole connecting downwards to a vertically positioned distribution cylinder 16, which is suspended above the bottom plate 5 of the tank. The distribution cylinder 16 connects the distribution chamber 8 and the space below the platform 14, forming a cylindrical channel. The platform 14 inside the tank is horizontally positioned and uses an overflow method to flow and distribute the slurry, which can effectively homogenize the composition of the slurry and avoid uneven distribution of slurry components.

[0031] A filter screen 14A is installed at each circular through-hole of the platform 14. Several vertically arranged partitions 17 are provided on the rear side of the platform 14, arranged along the front-rear direction of the housing and perpendicular to the platform 14. These partitions 17 divide the interior of the housing behind the platform 14 into several parallel grid spaces. Each grid space corresponds to a circular through-hole on the platform 14, and the number of grid spaces corresponds one-to-one with the number of circular through-holes on the platform 14. After the slurry in the storage tank 7 flows to the distribution room 8, it flows through the circular through-holes of the platform 14 and through the distribution cylinder 16 into the grid spaces formed by the partitions 17.

[0032] A vertically arranged flow-limiting baffle 18 is provided on the rear side of the slurry storage baffle 13. Both ends of the flow-limiting baffle 18 are fixed to the inner wall of the slurry storage tank 7, and the bottom of the flow-limiting baffle 18 is fixed to the bottom plate 5 of the tank. The flow-limiting baffle 18 and the slurry storage baffle 13 are arranged parallel to each other, and the height of the flow-limiting baffle 18 is lower than that of the platform 14. The slurry distribution trough 9 is formed between the flow-limiting baffle 18 and the slurry storage baffle 13. The slurry outlet trough 10 is formed between the flow-limiting baffle 18 and the rear plate 2 of the tank. The slurry outlet trough 10 is located in each compartment space, and a slurry outlet pipe 19 is provided on the bottom plate 5 of each slurry outlet trough 10. The slurry outlet pipe 19 is vertically arranged and connects the interior of the slurry outlet trough 10 to the exterior of the tank body. The slurry flows through the distribution cylinder 16 into the corresponding distribution tank 9, and then overflows through the top of the flow-limiting baffle 18 into the discharge tank 10, and is then supplied to external equipment through the discharge pipe 19 at the bottom of the discharge tank 10. The flow-limiting baffle 18 is designed to control the liquid level and flow rate of the slurry.

[0033] Preferably, the overflow port 11A on the slurry inlet baffle 11 is a rectangular opening, and a guide plate 11B is installed at the bottom of the opening of the overflow port 11A. The guide plate 11B includes an installation part 11C and an inclined plate part 11D connected together. The installation part 11C preferably adopts a structure with a U-shaped bayonet for installation and connection with the overflow port 11A of the slurry inlet baffle 11, and the inclined plate part 11D preferably adopts a downward inclined plate structure. When the guide plate 11B is installed at the overflow port 11A, the slurry overflowing from the slurry inlet tank 6 flows into the slurry storage tank 7 through the inclined plate part 11D, thus avoiding the wear of the slurry inlet baffle 11 and the damage to the overflow port 11A caused by flowing directly downwards along the overflow port 11A of the slurry inlet baffle 11.

[0034] Preferably, a grouting pipe 20 is provided on one side of the grout inlet trough 6 of the box body. The grouting pipe 20 is parallel to the front plate 1 of the box. The slurry from the grouting pipe 20 flows into the grout inlet trough 6 from one end. At this time, the overflow port 11A of the grout inlet baffle 11 is located on the part of the grout inlet baffle 11 away from the grouting pipe 20. A first wear-resistant plate 21 is placed at the bottom of the grout inlet trough 6 of the box body, covering the bottom area of ​​the grout inlet trough 6. When the slurry from the grouting pipe 20 is poured into the grout inlet trough 6, the heavier slurry will generate a drop impact force. The first wear-resistant plate 21 can effectively prevent the slurry from wearing and damaging the bottom plate 5 of the box body, extending its service life. Moreover, when the first wear-resistant plate 21 is worn, it can be easily replaced, reducing maintenance difficulty.

[0035] Preferably, a second wear-resistant plate 22 is placed at the bottom of the slurry distribution tank 9 of the box body, covering the bottom area of ​​the slurry distribution tank 9. When the slurry from the distribution chamber 8 flows into the slurry distribution tank 9 through the circular through-hole of the platform 14, the heavier slurry will generate a drop impact force. The second wear-resistant plate 22 can effectively prevent the slurry from wearing and damaging the bottom plate 5 of the box body, extending its service life. Since the present invention adopts an open design with a top opening, and each tank has an open structure, it is possible to place and replace the first wear-resistant plate 21 in the slurry inlet tank 6 and the second wear-resistant plate 22 in the slurry distribution tank 9. This is the technical advantage obtained by adopting the structure of the present invention.

[0036] A filter screen 14A is installed at each circular through hole of the platform 14. The filter screen 14A filters the flowing slurry, which not only separates the ore but also controls the particle size of the ore, filters out undesirable impurities, and improves the quality of the slurry. Moreover, the filtration operation is completed automatically during the overflow process, rather than being a separately set program, saving steps and processes.

[0037] In implementation of this invention, a grouting pipe 20 is installed on one side of the grout inlet trough 6 of the box body. The grouting pipe 20 is parallel to the front plate 1 of the box. The slurry from the grouting pipe 20 flows into the grout inlet trough 6 from one end. At this time, the overflow port 11A of the grout inlet baffle 11 is located on the portion of the grout inlet baffle 11 away from the grouting pipe 20. A first wear-resistant plate 21 is placed at the bottom of the grout inlet trough 6 of the box body, covering the bottom area of ​​the grout inlet trough 6. When the slurry from the grouting pipe 20 is injected into the interior of the grout inlet trough 6, the first wear-resistant plate 21 can effectively prevent the slurry from wearing down and damaging the bottom plate 5 of the box body.

[0038] Once the slurry in the feed tank 6 reaches a certain level, it will overflow into the storage tank 7 through the overflow port 11A of the feed baffle 11. The overflow method is used here to flow and distribute the slurry, which can effectively homogenize the composition of the slurry and avoid uneven distribution of the slurry composition.

[0039] The slurry is stored in the slurry tank 7, and the foam baffle 12 is located inside the slurry tank 7 and spaced between the slurry inlet baffle 11 and the slurry storage baffle 13. The foam baffle 12 plays a role in blocking foam in the slurry, which has a significant defoaming effect on the subsequent flotation process and helps to improve the process efficiency.

[0040] The slurry in the storage tank 7 overflows into the distribution chamber 8 through the platform 14. The platform 14 inside the tank uses an overflow method to flow and distribute the slurry. After the slurry in the storage tank 7 flows to the distribution chamber 8, it flows through the circular through-hole of the platform 14 and into the grid space formed by the partition plate 17 through the distribution cylinder 16.

[0041] The slurry flows through the distribution cylinder 16 into the corresponding distribution tank 9, and then overflows through the top of the flow-limiting baffle 18 into the discharge tank 10, and is then supplied to external equipment through the discharge pipe 19 at the bottom of the discharge tank 10. The flow-limiting baffle 18 is designed to control the liquid level and flow rate of the slurry.

[0042] The box used in this invention has an open design with an opening at the top. There are no connecting pipes or hidden passages inside, and each part can be directly observed and inspected. Moreover, the box structure is easier to operate and implement, providing a lot of convenience for maintenance and operation.

[0043] The container employs overflow mechanisms at multiple points to flow and distribute the slurry, effectively homogenizing its composition and preventing uneven distribution. This ensures consistent processing results across different subsequent equipment. This design is crucial for high-volume mineral processing scenarios or concentrators, as uniform slurry distribution directly impacts the consistency of subsequent processes and products.

[0044] The large amount of foam in the slurry is not conducive to subsequent mineral processing operations. The foam baffle 12 is set up to block the foam in the slurry, which has a great defoaming effect on the subsequent flotation process and helps to improve the process efficiency.

[0045] Because the present invention adopts an open design with a top opening, and each trough has an open structure, it is possible to place and replace the first wear-resistant plate 21 in the slurry inlet trough 6 and to place and replace the second wear-resistant plate 22 in the slurry distribution trough 9. This is the technical advantage obtained by adopting the structure of the present invention.

[0046] A filter screen 14A is installed at each circular through hole of the platform 14. The filter screen 14A filters the flowing slurry, which not only separates the ore but also controls the particle size of the ore, filters out undesirable impurities, and improves the quality of the slurry. Moreover, the filtration operation is completed automatically during the overflow process, rather than being a separately set program, saving steps and processes.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
