Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and in particular to a sludge collection device for thickeners. Background Technology

[0002] A thickener can concentrate slurry into a more solids-content underflow slurry through gravity settling, and the thickened underflow slurry is discharged from the bottom of the thickener by means of a plow that rotates inside the thickener.

[0003] The discharged underflow slurry still has a high water content and contains a large amount of recyclable materials, requiring further refining. Therefore, it needs to be collected and reused. Some collection equipment directly collects the water-containing sediment from the underflow slurry for secondary sedimentation. The water contained therein takes a lot of time to separate out, and the sediment after secondary sedimentation needs to be dredged out of the sedimentation tank before it can be reused. This is time-consuming, labor-intensive, and not conducive to improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sediment collection device for thickeners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sediment collection device for a thickener includes a collection vehicle and a collection plate. The top of the collection vehicle has a collection compartment, the bottom of the collection compartment is slidably connected to the collection plate, the bottom center of the collection plate is fixedly connected to a fixing ring, and the top of the collection vehicle has symmetrical filter grids on both sides.

[0007] It also includes a track and a mounting frame. The track is laid on the top of the paved ground. A mounting frame is fixedly installed on the top of the paved ground on both sides of the track. A first hydraulic rod is fixedly installed on the top of the mounting frame. The telescopic end of the first hydraulic rod extends out of the mounting frame. A pressure plate is fixedly connected to the end of the telescopic end of the first hydraulic rod. Drainage grooves are fixedly installed on the inner walls on both sides of the mounting frame. An installation cavity is opened in the paved ground below the mounting frame. A second hydraulic rod is fixedly installed on one side of the installation cavity. The second hydraulic rod is positioned corresponding to the first hydraulic rod. A fourth hydraulic rod is fixedly installed on the other side of the installation cavity. Through holes are opened in the paved ground above the second and fourth hydraulic rods.

[0008] Preferably, the bottom of the collection vehicle is rotatably mounted with track wheels, which are rolled onto the track.

[0009] Preferably, the inner wall of the collection chamber is provided with guide rails around its perimeter, a limit block is provided at the bottom of the guide rails, and guide rail grooves are provided around the collection plate to slide and connect with the guide rails.

[0010] Preferably, the side wall of the collection vehicle outside the filter grid is provided with a guide channel, and the distance between the bottom end of the guide channel and the bottom end of the track wheel is greater than the distance between the bottom end of the guide channel and the bottom end of the paved ground.

[0011] Preferably, the outer walls on both sides of the mounting frame are fixedly equipped with discharge ports that are respectively connected to two drainage channels, and a collection pool is provided on the paved ground below the two discharge ports.

[0012] Preferably, a third hydraulic rod is symmetrically arranged in the mounting cavities on both sides of the second hydraulic rod, and the telescopic ends of the two third hydraulic rods are fixedly connected to a stop block that is slidably connected to the top of the paved ground.

[0013] Preferably, a belt conveyor is fixedly installed at the top of the paved ground on one side of the fourth hydraulic rod, and a fifth hydraulic rod is fixedly installed at the top of the paved ground on the other side of the fourth hydraulic rod, with a push plate fixedly connected to the output end of the fifth hydraulic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a collection vehicle designed to collect sediment discharged from a thickener. The track is continuously laid, passing under the discharge port of the thickener, then under the mounting frame, and finally connecting with the track below the thickener to form a rotary unit. This allows the collection vehicle to move back and forth on the track, achieving a cyclical operation of collecting sediment from the discharge port, compressing and draining the sediment, conveying the sediment, and collecting sediment from the discharge port. In actual use, multiple collection vehicles are installed on the track, allowing them to work continuously without waiting at any stage, thus improving collection efficiency.

[0016] This invention utilizes a first hydraulic rod and a second hydraulic rod, which work together to compress the sediment, causing the water in the sediment to be squeezed out by the pressure plate and collection plate. The squeezed water then flows out through the filter screen and into the collection tank for collection via the diversion channel. By using the cooperation of the first and second hydraulic rods to squeeze out the water from the sediment, the time consumed in the secondary utilization of the sediment can be greatly reduced, and it can be reused without secondary sedimentation, effectively improving the reuse efficiency of the sediment.

[0017] This invention utilizes a fifth hydraulic rod and a belt conveyor. The fifth hydraulic rod extends to push a pusher plate, moving the sediment onto the belt conveyor, which then transports it to the subsequent processing station. Through the combined use of the fifth hydraulic rod and the belt conveyor, the compressed sediment is transported out of the collection vehicle, allowing the collection vehicle to return to the discharge port via a track to continue collecting sediment. This ensures a smooth and cyclical operation, improving the collection efficiency of the sediment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A sediment collection device for a thickener includes a collection vehicle 1 and a collection plate 5. A collection chamber 3 is provided on the top of the collection vehicle 1, and the collection plate 5 is slidably connected to the bottom of the collection chamber 3. A fixing ring 51 is fixedly connected to the center of the bottom end of the collection plate 5. Filter grids 6 are symmetrically provided on both sides of the top of the collection vehicle 1.

[0026] It also includes a track 9 and a mounting frame 10. The track 9 is laid on the top of the paved ground 8. A mounting frame 10 is fixedly installed on the top of the paved ground 8 on both sides of the track 9. A first hydraulic rod 11 is fixedly installed on the top of the mounting frame 10. The telescopic end of the first hydraulic rod 11 extends out of the mounting frame 10. A pressure plate 12 is fixedly connected to the end of the telescopic end of the first hydraulic rod 11. Drainage grooves 13 are fixedly installed on the inner walls on both sides of the mounting frame 10. An installation cavity 15 is opened in the paved ground 8 below the mounting frame 10. A second hydraulic rod 16 is fixedly installed on one side of the installation cavity 15. The second hydraulic rod 16 is positioned corresponding to the first hydraulic rod 11. A fourth hydraulic rod 19 is fixedly installed on the other side of the installation cavity 15. Through holes are opened in the paved ground 8 above the second hydraulic rod 16 and the fourth hydraulic rod 19. The collection cart 1 is used to collect the sediment discharged from the thickener. The track 9 is continuously laid, passing under the discharge port of the thickener, then under the mounting frame 10, and finally connecting with the track 9 below the thickener to form a rotary unit. This allows the collection cart 1 to move back and forth on the track 9, realizing a cyclical operation of collecting sediment from the discharge port, compressing and draining, conveying sediment, and collecting sediment from the discharge port. In actual use, multiple collection carts 1 are installed on the track 9, allowing multiple collection carts 1 to work continuously without waiting at any stage, thus improving collection efficiency. The sediment discharged from the discharge port flows into the collection bin 3 and is supported by the collection plate 5. At this time, the collection plate 5 is located at the bottom of the collection bin 3. The collection cart 1 is moved to under the mounting frame 10, and then the third hydraulic rod 17 near the belt conveyor 20 pushes the stop block 18 to limit the forward movement of the collection cart 1, stopping it at the predetermined position. Then, another third hydraulic rod 17 pushes another stop block 18 to further limit the movement of the collection cart. 1. A limit switch is installed at the rear, preventing the collection vehicle 1 from moving forward or backward. This ensures that the subsequent compression and drainage of the sediment will not be adversely affected by the displacement of the collection vehicle 1. At this time, the position of the collection vehicle 1 is fixed, and the extension of the second hydraulic rod 16 and the first hydraulic rod 11 can be controlled so that the end of the second hydraulic rod 16 connects to the fixing ring 51 and pushes the collection plate 5 to rise along the guide rail 4. Meanwhile, the first hydraulic rod 11 pushes the pressure plate 12 down into the collection chamber 3. Finally, the collection plate 5 pushes the sediment to rise and is squeezed by the pressure plate 12, so that the water in the sediment is squeezed out by the pressure plate 12 and the collection plate 5. The squeezed water flows out through the filter screen 6 and flows into the collection pool 14 through the diversion channel 13 for collection. At this time, the water in the sediment is squeezed out by the cooperation of the first hydraulic rod 11 and the second hydraulic rod 16, which can greatly reduce the time consumed by the secondary utilization of sediment. It can be reused without secondary sedimentation, effectively improving the reuse efficiency of sediment.

[0027] As a technical optimization of this utility model, the bottom of the collection vehicle 1 is rotatably equipped with track wheels 2, which are rolled onto the track 9. The track wheels 2 roll on the track 9, which both limits the movement of the track wheels 2 and facilitates the cyclical movement of the collection vehicle 1.

[0028] As a technical optimization of this utility model, guide rails 4 are provided around the inner wall of the collection chamber 3, and a limiting block is provided at the bottom of the guide rails 4. Guide rail grooves that slide and connect with the guide rails 4 are opened around the collection plate 5. The guide rails 4 facilitate the up and down movement of the collection plate 5. In actual use, a sealing element is provided between the collection plate 5, the collection chamber 3, and the guide rails 4, which can effectively reduce leakage and reduce cleaning difficulty. Since the collection chamber 3 is vertically continuous to facilitate the movement of the second hydraulic rod 16, the limiting block can prevent the collection plate 5 from falling off.

[0029] As a technical optimization of this utility model, a guide channel 7 is provided on the side wall of the collection vehicle 1 outside the filter grid 6. The distance between the bottom end of the guide channel 7 and the bottom end of the track wheel 2 is greater than the distance between the bottom end of the diversion channel 13 and the bottom end of the paved ground 8. The purpose of this greater distance is that when the collection vehicle 1 moves to the area below the mounting frame 10, the guide channel 7 and the diversion channel 13 do not interfere with each other but can still function as a means of water flow.

[0030] As a technical optimization of this utility model, the outer walls of both sides of the mounting frame 10 are fixedly equipped with discharge ports that are respectively connected to two diversion channels 13, and a collection pool 14 is provided on the paved ground 8 below the two discharge ports. The water squeezed out from the sediment eventually flows into the collection pool 14 through the discharge ports for centralized treatment.

[0031] As a technical optimization of this utility model, third hydraulic rods 17 are symmetrically arranged in the mounting cavities 15 on both sides of the second hydraulic rod 16. The telescopic ends of the two third hydraulic rods 17 are fixedly connected to a stop block 18 that is slidably connected to the top of the paved ground 8. Both third hydraulic rods 17 are arranged along the direction of the track 9. Through the cooperation of the two third hydraulic rods 17 and the stop block 18, the collection vehicle 1 is positioned directly below the mounting frame 10, so that the pressure plate 12 can be accurately pushed into the collection chamber 3 for compression. Furthermore, the stop block 18 is slidably connected to the paved ground 8. When the stop block 18 is under force, the paved ground 8 bears the force and will not damage the third hydraulic rods 17.

[0032] As a technical optimization of this utility model, a belt conveyor 20 is fixedly installed at the top of the paved ground 8 on one side of the fourth hydraulic rod 19, and a fifth hydraulic rod 21 is fixedly installed at the top of the paved ground 8 on the other side of the fourth hydraulic rod 19. A push plate 22 is fixedly connected to the output end of the fifth hydraulic rod 21. After extrusion, the first hydraulic rod 11 and the second hydraulic rod 16 retract, the collecting plate 5 descends to the bottom of the collecting chamber 3, the two third hydraulic rods 17 retract, the stop block 18 loses its limiting function, and the collecting cart 1 continues to move above the fourth hydraulic rod 19. The fourth hydraulic rod 19 is controlled to extend and push the collecting plate 5 up along the guide rail 4 until the top of the collecting plate 5 is flush with the top of the collecting cart 1, thus pushing the compacted sediment out of the collecting chamber 3. At this time, the fifth hydraulic rod 21 extends and pushes the push plate 22 to move the sediment onto the belt conveyor 20, which then transports it to the subsequent processing station. Through the combined use of the fifth hydraulic rod 21 and the belt conveyor 20, the extruded sediment is transported out of the collecting cart 1, allowing the collecting cart 1 to return to the discharge port via the track 9 to continue collecting sediment. This makes the entire operation process smooth and cyclical, improving the collection efficiency of the sediment. The hydraulic telescopic rods used in this utility model are all powered by the hydraulic station of the thickener, and the control method is manual operation by the local control cabinet, with accompanying operating steps.

[0033] In use, a collection cart 1 moves to below the thickener discharge port. The sediment discharged from the discharge port flows into the collection bin 3 and is supported by the collection plate 5. At this time, the collection plate 5 is located at the bottom of the collection bin 3. The collection cart 1 is moved to below the mounting frame 10. Then, the third hydraulic rod 17 near the belt conveyor 20 pushes the stop block 18 to limit the front of the collection cart 1, so that the collection cart 1 stops at the predetermined position. Then, another third hydraulic rod 17 pushes another stop block 18 to limit the rear of the collection cart 1, so that the collection cart 1 cannot move forward or backward. At this time, the position of the collection cart 1 is fixed. The second hydraulic rod 16 and the first hydraulic rod 11 can be controlled to extend, so that the end of the second hydraulic rod 16 connects to the fixing ring 51 and pushes the collection plate 5 to rise along the guide rail 4. The first hydraulic rod 11 pushes the pressure plate 12 down into the collection bin 3. Finally, the collection plate 5 pushes the sediment to rise and is squeezed by the pressure plate 12, so that the water in the sediment is removed. The pressing plate 12 and collecting plate 5 squeeze out the sediment, and the squeezed water flows out through the filter grid 6 and into the collection tank 14 through the diversion channel 13 for collection. After the squeezing is completed, the first hydraulic rod 11 and the second hydraulic rod 16 both retract, the collecting plate 5 descends to the bottom of the collecting bin 3, the two third hydraulic rods 17 retract, the stop block 18 fails to limit, and the collecting cart 1 continues to move to the top of the fourth hydraulic rod 19. The fourth hydraulic rod 19 is controlled to extend and push the collecting plate 5 to rise along the guide rail 4. Finally, the top of the collecting plate 5 is flush with the top of the collecting cart 1, and the compacted sediment is pushed out of the collecting bin 3. At this time, the fifth hydraulic rod 21 extends and pushes the push plate 22 to push the sediment to the belt conveyor 20, and then the belt conveyor 20 transports it to the subsequent processing station. The fourth hydraulic rod 19 and the fifth hydraulic rod 21 reset, the collecting plate 5 descends back to the bottom of the collecting bin 3, and the collecting cart 1 continues to move along the track 9 and returns to the bottom of the discharge port to continue collecting sediment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
