Description

Technical Field

[0001] This utility model relates to the technical field of sulfur concentrate waste liquid recovery, specifically to a waste liquid recovery structure for a sulfur concentrate sedimentation tank. Background Technology

[0002] After the flotation process of sulfur concentrate is completed, the slurry is separated into solid and liquid components by a filter press to form ore blocks. This process generates a large amount of waste liquid containing sulfur concentrate particles. This waste liquid is a solid-liquid mixture, mainly composed of sulfur concentrate particles, residual flotation reagents, and water. After being discharged, the waste liquid flows into a waste liquid channel and moves along the bottom of the channel under gravity.

[0003] Due to the high density and small particle size of sulfur concentrate, these particles gradually settle and accumulate at the bottom of the wastewater channel during wastewater flow, forming a sediment layer. Simultaneously, residual flotation reagents in the wastewater enhance the adhesion between sulfur concentrate particles, causing them not only to settle at the bottom but also to adhere to the inner wall of the wastewater channel, forming an adhesion layer. As the wastewater continues to flow, the sediment layer at the bottom of the channel and the adhesion layer on the inner wall gradually thicken, resulting in a continuous reduction in the effective flow cross-section and flow velocity within the channel. This not only increases the risk of blockage in the wastewater channel but also prevents some sulfur concentrate particles from smoothly entering the recovery system, thus leading to a decrease in the sulfur concentrate recovery rate.

[0004] To solve this problem, staff need to clean the waste liquid channel frequently, and each cleaning takes a long time. This not only reduces the overall production efficiency but also increases the cost of manual cleaning. Utility Model Content

[0005] The present invention aims to provide a waste liquid recovery structure for a sulfur concentrate sedimentation tank, which can avoid manual cleaning of waste liquid channels, thereby improving overall production efficiency and reducing production costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] 1) A waste liquid recovery structure for a sulfur concentrate sedimentation tank, comprising a central recovery tank, wherein several radially distributed inclined waste liquid channels are evenly distributed along the circumference of the central recovery tank, the inclined waste liquid channels are used to collect the surrounding waste liquid, the bottom surface of the inclined waste liquid channels is inclined towards the central recovery tank, all inclined waste liquid channels are connected to the central recovery tank, and several flushing mechanisms for flushing the inclined waste liquid channels are evenly distributed above each inclined waste liquid channel along its axial direction.

[0008] In this invention, the bottom surface of the inclined waste liquid channel is inclined towards the central recovery tank. Gravity guides the waste liquid towards the central recovery tank, shortening the residence time of the waste liquid in the inclined waste liquid channel and thus improving the waste liquid recovery efficiency. Simultaneously, it ensures that waste liquid from each inclined waste liquid channel flows into the central recovery tank, facilitating subsequent centralized treatment or reuse.

[0009] The flushing mechanism, evenly distributed along the axial direction of the inclined wastewater channel, effectively removes sediment from the bottom and the adhesion layer on the inner wall, preventing the accumulation of sediment and the thickening of the adhesion layer. This avoids reducing the flow cross-section of the inclined wastewater channel due to increased sediment and adhesion layers, thereby further improving wastewater transport efficiency. Flushing the inclined wastewater channel with this mechanism eliminates the need for manual cleaning, thus improving overall production efficiency and reducing production costs.

[0010] 2) According to the waste liquid recovery structure of the sulfur concentrate sedimentation tank described in 1), wherein:

[0011] The flushing mechanism includes a flushing frame erected above the inclined waste liquid channel. The flushing frame includes a flushing pipe parallel to the radial direction of the inclined waste liquid channel. The two ends of the flushing pipe are closed. The flushing pipe faces the inclined waste liquid channel and flushes the inclined waste liquid channel.

[0012] In this invention, the flushing frame is mounted above the inclined waste liquid channel, and the flushing pipe is parallel to the radial direction of the channel, allowing it to directly flush the inner wall and bottom of the channel. During flushing, the flushing water is sprayed onto the inner wall and bottom of the channel, effectively removing deposits and adhesion layers. This direct flushing method prevents the accumulation of bottom deposits and the thickening of the adhesion layer on the inner wall, avoiding a reduction in the flow cross-section of the channel due to increased deposits and adhesion layers. This improves the waste liquid transport efficiency, ensures smooth flow of waste liquid, and reduces residence time.

[0013] By flushing the inclined wastewater channel with a flushing mechanism, manual cleaning can be avoided, thereby significantly improving production efficiency and reducing labor costs and maintenance expenses.

[0014] 3) According to the waste liquid recovery structure of the sulfur concentrate sedimentation tank described in 2), wherein:

[0015] The flushing pipe is connected to vertical plates at both ends, and each vertical plate has a circular hole. The inclined waste liquid channel has vertical rods on both sides that correspond to the vertical plates. Each vertical rod has a strip hole along its axis. Bolts are inserted into the circular holes and the strip holes, and nuts are threaded onto the bolts.

[0016] In this invention, vertical plates are located at both ends of the flushing pipe and are used to connect the flushing pipe to the vertical rod. By simultaneously passing bolts through both the circular and rectangular holes and tightening the nuts, a fixed connection between the vertical plates and the vertical rod can be achieved. This connection method ensures that the flushing pipe remains stable during operation and will not loosen or shift due to water flow impact or other external forces.

[0017] When the height of the flushing pipe needs to be adjusted, the vertical plate can be moved up and down within the slotted hole of the vertical rod by loosening the nut. This setting allows the height of the flushing pipe to be flexibly adjusted according to flushing needs to achieve the best flushing effect. After adjusting to the appropriate height, tighten the nut again to fix the vertical plate to the vertical rod, thereby ensuring that the flushing pipe can work stably at the new height.

[0018] 4) A waste liquid recovery structure for a sulfur concentrate sedimentation tank as described in 2), wherein:

[0019] The flushing pipe includes an inlet pipe and a main bushing. One end of the inlet pipe is connected to an inlet mechanism, and the other end of the inlet pipe is connected to the middle of the main bushing. The central axis of the main bushing is perpendicular to the central axis of the inlet pipe. The two ends of the main bushing are respectively rotatably connected to first connecting pipes. The opposite ends of the two first connecting pipes are each connected to a secondary bushing. The other end of each secondary bushing is respectively rotatably connected to a second connecting pipe. The end of the second connecting pipe opposite to the secondary bushing is connected to a side bushing. The side bushing, the secondary bushing, and the main bushing are respectively connected to spray pipes. The end of the spray pipe is rotatably connected to a spiral spray nozzle.

[0020] In this invention, one end of the water inlet pipe is connected to a water inlet mechanism, which introduces water from the water inlet mechanism into the main shaft sleeve to supply water to the entire flushing pipe. The stable water supply from the water inlet pipe ensures that the water flow is continuous and even throughout the entire flushing pipe, providing a stable water flow for subsequent flushing operations.

[0021] Each end of the main bushing is rotatably connected to a first connecting pipe, the other end of which is connected to a secondary bushing. The other end of each secondary bushing is rotatably connected to a second connecting pipe, the other end of which is connected to a side bushing. This rotatable connection of the main bushing, secondary bushing, and side bushings makes the entire flushing pipe more flexible. By utilizing the rotational properties of the side bushing, secondary bushing, and main bushing, the flushing direction of the spray pipe connected to these bushings can be changed. Therefore, according to different locations within the inclined wastewater channel and flushing requirements, the spray pipe at each location can be rotated to change the flushing direction, thereby improving flushing efficiency.

[0022] The end of the spray pipe is fitted with a helical nozzle via a rotatable connection, allowing the water to be sprayed out in a spiral pattern. This helical spray not only expands the coverage area of ​​the water flow but also enhances its impact force, thereby more efficiently removing sediment and adhering layers from inclined waste channels and significantly improving flushing effectiveness. Furthermore, the rotatable connection between the spray pipe and the helical nozzle allows the spray direction of the nozzle to be adjusted as needed, further enhancing the flexibility and adaptability of the flushing operation.

[0023] 5) A waste liquid recovery structure for a sulfur concentrate sedimentation tank as described in 4), wherein:

[0024] The water inlet mechanism includes a water tank, the outlet of which is connected to one end of the water inlet pipe via a flexible hose, and a suction pump is connected to the flexible hose.

[0025] In this invention, a water tank is used to store the water required for the rinsing operation, providing a sufficient water source to ensure the continuous operation. The outlet of the water tank is connected to one end of the inlet pipe via a flexible hose, and a suction pump is connected to the hose. When the suction pump is started, it draws water from the tank and sends it into the flexible hose. The water then flows through the inlet pipe into the rinsing pipe and is finally sprayed out through a spiral nozzle, forming a highly efficient rinsing water flow to ensure the smooth progress of the rinsing operation.

[0026] 6) A waste liquid recovery structure for a sulfur concentrate sedimentation tank as described in 1), wherein:

[0027] The inclined waste liquid channel is inclined at a 30° angle to the horizontal direction.

[0028] In this invention, the inclined waste liquid channel is inclined at a 30° angle to the horizontal. This 30° angle fully utilizes gravity, allowing the waste liquid to flow naturally towards the central recovery tank under gravity, eliminating the need for additional power and thus effectively saving energy and operating costs.

[0029] Compared with the prior art, this utility model also has the following technical effects:

[0030] This invention uses a flushing pipe to rinse the bottom and inner walls of an inclined wastewater channel, effectively removing sediment from the bottom and adhering layers from the inner walls, thereby improving wastewater transport efficiency. Compared to existing technologies, this invention eliminates the need for manual cleaning, thus improving overall production efficiency and reducing production costs. Furthermore, the flushing direction can be changed by rotating the spray pipe and spiral nozzle at each location within the inclined wastewater channel according to different positions and flushing requirements, further enhancing flushing efficiency.

[0034] The following detailed description illustrates the specific implementation method:

[0035] The reference numerals in the accompanying drawings include: central recovery tank 1, inclined waste liquid channel 2, rotating rod 3, vertical plate 4, vertical rod 5, bolt 6, water inlet pipe 7, main shaft sleeve 8, first connecting pipe 9, secondary shaft sleeve 10, second connecting pipe 11, side shaft sleeve 12, spray pipe 13, spiral spray nozzle 14, water tank 15, suction pump 16.

[0036] See the example. Figure 1 , Figure 2 as well as Figure 3 As shown in the figure, the waste liquid recovery structure of the sulfur concentrate sedimentation tank in this embodiment includes a central recovery tank 1. The central recovery tank 1 has several radially distributed inclined waste liquid channels 2. The inclined waste liquid channels 2 are used to collect the surrounding waste liquid. The bottom surface of the inclined waste liquid channels 2 is inclined towards the central recovery tank 1. All inclined waste liquid channels 2 are connected to the central recovery tank 1. Several flushing mechanisms for flushing the inclined waste liquid channels 2 are evenly distributed above each inclined waste liquid channel 2 along its axial direction.

[0037] In this embodiment, the bottom surface of the inclined waste liquid channel 2 is inclined towards the central recovery tank 1. Gravity guides the waste liquid towards the central recovery tank 1, shortening the residence time of the waste liquid in the inclined waste liquid channel 2 and thus improving the waste liquid recovery efficiency. Simultaneously, it ensures that the waste liquid in each inclined waste liquid channel 2 can flow into the central recovery tank 1, facilitating subsequent centralized treatment or reuse.

[0038] The flushing mechanism, evenly distributed along the axial direction of the inclined waste liquid channel 2, effectively flushes the channel, removing sediment from the bottom and the adhesion layer on the inner wall. This prevents the accumulation of sediment and the thickening of the adhesion layer, avoiding a reduction in the flow cross-section of the channel due to increased sediment and adhesion, thus further improving waste liquid transport efficiency. Flushing the inclined waste liquid channel 2 with this mechanism eliminates the need for manual cleaning, thereby improving overall production efficiency and reducing production costs.

[0039] The flushing mechanism includes a flushing frame erected above the inclined waste liquid channel 2. The flushing frame includes a flushing pipe parallel to the radial direction of the inclined waste liquid channel 2. Both ends of the flushing pipe are closed, and the flushing pipe faces the inclined waste liquid channel 2 and flushes the inclined waste liquid channel 2. In this embodiment, the flushing frame is erected above the inclined waste liquid channel 2, and the flushing pipe is parallel to the radial direction of the inclined waste liquid channel 2, so that the flushing pipe can directly aim at the inner wall and bottom of the inclined waste liquid channel 2 for flushing.

[0040] During the flushing process, the flushing water jets can be sprayed onto the inner wall and bottom of the inclined waste liquid channel 2, effectively removing deposits and adhesion layers accumulated in these areas. This direct flushing method prevents the accumulation of bottom deposits and the thickening of the adhesion layer on the inner wall, avoiding a reduction in the flow cross-section of the inclined waste liquid channel 2 due to increased deposits and adhesion layers. This improves the waste liquid transport efficiency, ensures smooth flow of waste liquid, and reduces residence time. Flushing the inclined waste liquid channel 2 using a flushing mechanism eliminates the need for manual cleaning, significantly improving production efficiency while reducing labor and maintenance costs.

[0041] Vertical plates 4 are connected to both ends of the flushing pipe. The vertical plates 4 have circular holes. Vertical rods 5, which correspond one-to-one with the vertical plates 4, are provided on the outside of both sides of the inclined waste liquid channel 2. The vertical rods 5 have strip holes along their axial direction. Bolts 6 are inserted into the circular holes and the strip holes. Nuts are threaded onto the bolts.

[0042] In this embodiment, the vertical plates 4 are located at both ends of the flushing pipe and are used to connect the flushing pipe to the vertical rod 5. By passing the bolts 6 through both the circular hole and the strip hole simultaneously and tightening the nuts, the vertical plates 4 and the vertical rod 5 can be fixedly connected. This connection method ensures that the flushing pipe remains stable during operation and will not loosen or shift due to water flow impact or other external forces.

[0043] When the height of the flushing pipe needs to be adjusted, the vertical plate 4 can move up and down within the slot of the vertical rod 5 by loosening the nut. This setting allows the height of the flushing pipe to be flexibly adjusted according to flushing needs to achieve the best flushing effect. After adjusting to the appropriate height, tighten the nut again to fix the vertical plate 4 on the vertical rod 5, thereby ensuring that the flushing pipe can work stably at the new height.

[0044] The flushing pipe includes an inlet pipe 7 and a main shaft sleeve 8. One end of the inlet pipe 7 is connected to an inlet mechanism, and the other end of the inlet pipe 7 is connected to the middle of the main shaft sleeve 8. The central axis of the main shaft sleeve 8 is perpendicular to the central axis of the inlet pipe 7. The two ends of the main shaft sleeve 8 are respectively rotatably connected to first connecting pipes 9. The two opposite ends of the first connecting pipes 9 are each connected to a secondary shaft sleeve 10. The other end of each secondary shaft sleeve 10 is respectively rotatably connected to a second connecting pipe 11.

[0045] The second connecting pipe 11 is connected to a side bushing 12 at the end opposite to the secondary bushing 10. Each side bushing 12 is rotatably connected to a rotating rod 3 at the end opposite to the second connecting pipe 11. The other end of each rotating rod 3 is fixedly connected to the vertical plate 4. The side bushing 12, the secondary bushing 10 and the main bushing 8 are respectively connected to a spray pipe 13. The end of the spray pipe 13 is rotatably connected to a spiral spray nozzle 14.

[0046] In this embodiment, one end of the water inlet pipe 7 is connected to a water inlet mechanism. The water inlet pipe 7 introduces water from the water inlet mechanism into the main shaft sleeve 8 to supply water to the entire flushing pipe. The stable water supply from the water inlet pipe 7 ensures that the water flow can continuously and evenly flow into the entire flushing pipe, providing a stable water flow for subsequent flushing operations.

[0047] The main shaft sleeve 8 is rotatably connected to two ends of a first connecting pipe 9, and the other end of the first connecting pipe 9 is connected to a secondary shaft sleeve 10. The other end of each secondary shaft sleeve 10 is rotatably connected to a second connecting pipe 11, and the other end of the second connecting pipe 11 is connected to a side shaft sleeve 12. The rotatable connection of the main shaft sleeve 8, secondary shaft sleeve 10, side shaft sleeve 12 and rotating rod 3 makes the entire flushing pipe more flexible.

[0048] By utilizing the rotational properties of the side bushing 12, secondary bushing 10, and main bushing 8, the flushing direction of the spray pipe 13 connected by the side bushing 12, secondary bushing 10, and main bushing 8 can be changed. Thus, according to different positions and flushing requirements within the inclined waste liquid channel 2, the spray pipe 13 at each position can be rotated to change the flushing direction, thereby improving the flushing efficiency.

[0049] A spiral nozzle 14 is rotatably connected to the end of the spray pipe 13, allowing the water to be sprayed out in a spiral pattern. This spiral spray not only expands the coverage area of ​​the water flow but also enhances its impact force, thereby more efficiently removing sediment and adhering layers from the inclined waste channel 2 and significantly improving the flushing effect. Furthermore, the rotatable connection between the spray pipe 13 and the spiral nozzle 14 allows the spray direction of the spiral nozzle 14 to be adjusted as needed, further enhancing the flexibility and adaptability of the flushing operation.

[0050] The water inlet mechanism includes a water tank 15. The outlet of the water tank 15 is connected to one end of the water inlet pipe 7 via a hose, and a suction pump 16 is connected to the hose. In this embodiment, the water tank 15 is used to store the water required for the rinsing operation, providing a sufficient water source for the rinsing operation and ensuring that the rinsing operation can be carried out continuously. The outlet of the water tank 15 is connected to one end of the water inlet pipe 7 via a hose, and a suction pump 16 is connected to the hose. When the suction pump 16 is started, it draws water from the water tank 15 and sends it into the hose. Then, the water flows through the water inlet pipe 7 into the rinsing pipe, and finally is sprayed out through the spiral spray nozzle 14 to form a high-efficiency rinsing water flow, ensuring the smooth progress of the rinsing operation.

[0051] The inclined waste liquid channel 2 is inclined at a 30° angle to the horizontal direction. In this embodiment, the inclined waste liquid channel 2 is inclined at a 30° angle to the horizontal direction. The 30° inclination angle can make full use of gravity, allowing the waste liquid to flow naturally towards the central recovery tank 1 under the action of gravity, without the need for additional power, thereby effectively saving energy and operating costs.

[0052] This embodiment uses a flushing pipe to flush the bottom and inner wall of the inclined waste liquid channel 2, effectively removing sediment from the bottom and adhering layer from the inner wall, thereby improving the waste liquid transport efficiency. Compared with the prior art, this embodiment avoids manual cleaning, thus improving overall production efficiency and reducing production costs.
