Abstract

This invention provides a mud-water solid-liquid separation device with screening function, relating to the field of mud-water separation technology. The device includes a separation processing tank with a discharge frame at the top. Foldable plates are fixedly connected to both sides of the discharge frame and the inner sides of the separation processing tank. Feed frames are fixedly connected to both sides of the discharge frame. The device conveys mud and water into the separation processing tank through the discharge frame, and filters and separates the mud and water through a filter plate. When the discharge frame discharges material, a first motor is started. The output of the first motor drives a first reciprocating screw to rotate.

[0003] The above solution has many advantages, but it also has the following drawbacks:

[0004] 1. Existing devices separate mud and water through a filter screen. The mud and water tend to fall to the same spot, which means that other parts of the filter screen cannot be fully utilized.

[0005] 2. When mud and water accumulate together on the filter screen, a large amount of water is also trapped in the mud, making it impossible to separate them completely;

[0006] 3. After filtration, a large amount of sand will accumulate on top of the filter screen, requiring manual cleaning, which is too tedious. Summary of the Invention

[0018] Preferably, a drain pipe for drainage is installed inside the separation and treatment box, and a control valve is installed on the outside of the drain pipe.

[0019] This invention provides a mud-water solid-liquid separation device with screening function, which has the following beneficial effects:

[0020] 1. This mud-water solid-liquid separation equipment with screening function conveys mud and water into the separation and processing box through a feeding frame, and filters and separates mud and water through a filter plate. When the feeding frame discharges material, the first motor can be started. The output end of the first motor drives the first reciprocating screw to rotate. When the first motor rotates, it drives the feeding frame to move back and forth on the top of the separation and processing box, so that the mud and water can be evenly poured onto the filter plate, thereby improving the filtration effect of the filter plate and avoiding the material from being too concentrated, which would affect the filtration effect.

[0021] 2. This mud-water solid-liquid separation equipment with screening function, when the second sprocket rotates, it drives the first sprocket to rotate through the chain. The rotation of the first sprocket drives the fixedly connected transmission rod to rotate. The rotation of the transmission rod drives the fixedly connected second steering gear. The second steering gear drives the meshing first steering gear, so that the second reciprocating screw drives the connecting plate to push the lower pressure plate to reciprocate and rise. Thus, the lower pressure plate continuously squeezes the mud and water inside the feeding frame to discharge the material, thereby increasing the falling rate.

[0022] 3. This mud-water solid-liquid separation equipment with screening function moves along with the fixed cleaning side plate when the moving plate moves. A connecting seat is fixedly connected to one side of the cleaning side plate, and multiple fixed cylinders are fixedly connected to the bottom of the connecting seat. When the moving plate moves, the chain drive of the third and fourth sprockets causes the fourth sprocket to drive the fixed drive shaft to rotate. When the drive shaft rotates, it drives the fixed rotating disk to rotate, and the rotating disk drives the rotating shaft to rotate. Since the rotating shaft is in the groove opened in the swing plate, the swing plate swings back and forth around the positioning rod. The sector gear fixedly connected to one end of the swing plate drives the meshing rack to move back and forth. The connecting seat also moves along with the rack. Under the action of the spring inside the fixed cylinder, the spring pushes the fixed disk. The actuating plate at the bottom of the sliding rod contacts the top of the filter plate. As the actuating plate moves along with the connecting seat, it agitates the mud and water, so that the mud and water are fully separated, improving the mud-water separation effect.

[0023] 4. This mud-water solid-liquid separation equipment with screening function, through the activation of the swing plate to reciprocate, the sector gear drives the connecting seat to move back and forth. Due to the meshing connection between the outer gear ring and the connecting rack, the outer gear ring rotates, thereby cleaning the top of the filter plate with the cleaning brush. The cleaning side plate pushes the mud, and the electric telescopic rod inside the collection frame is activated. The electric telescopic rod drives the baffle to rotate, opening the collection frame. At this time, the mud is pushed into the sliding box for collection under the action of the cleaning side plate and the cleaning brush, thereby achieving the effect of cleaning the filter plate, avoiding manual cleaning, improving the filtration effect, and also enabling the mud and water to be fully separated.

[0037] This invention provides a mud-water solid-liquid separation device with screening function.

[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The separation processing box 1 includes a feeding frame 2 on the top of the separation processing box 1. Foldable plates 4 are fixedly connected between the two sides of the feeding frame 2 and the two sides inside the separation processing box 1. Feeding frames 3 are fixedly connected to both sides of the feeding frame 2. A moving component 5 for moving the feeding frame 2 to feed materials is provided on the outside of the separation processing box 1.

[0039] The separation and processing box 1 is equipped with a filter plate 6. Four first hydraulic telescopic rods 601 are fixedly connected to the bottom of the filter plate 6. All four first hydraulic telescopic rods 601 are fixedly connected to the inner wall of the separation and processing box 1. A movable plate 7 is provided on the top of the filter plate 6. A cleaning side plate 8 is fixedly connected to the bottom of the movable plate 7. A connecting seat 801 is slidably connected to one side of the cleaning side plate 8. Multiple fixed cylinders 10 are fixedly connected to the bottom of the connecting seat 801. A cleaning component for swinging is provided between the cleaning side plate 8 and the movable plate 7.

[0040] Both sides of the separation and processing box 1 are fixedly connected to collection frames 9 for collection.

[0041] The moving component 5 includes two first reciprocating screws 501, each with a sliding groove on its outer side. Fixed plates 511 are fixedly connected to both sides of the feeding frame 2. The two first reciprocating screws 501 pass through the two fixed plates 511 and are connected to them via ball bearing nuts. A lower pressure plate 503 is provided inside the feeding frame 2. Two connecting plates 504 are fixedly connected to the top of the lower pressure plate 503. First support plates 502 are rotatably connected to the outer sides of the two first reciprocating screws 501. The first support plates 502 are fixedly connected to the separation processing box 1. Two first motors 513 are fixedly connected to the outer side of the separation processing box 1. The output ends of the two first motors 513 are fixedly connected to the two first reciprocating screws 501, allowing the first reciprocating screws 501 to drive the feeding frame 2 to reciprocate through the fixed plates 511, thus ensuring uniform feeding. The moving component 5 also includes two second reciprocating screws 512. Both second reciprocating screws 512 pass through the top of the feeding frame 2 and are rotatably connected to the feeding frame 2. A connecting plate 504 is connected to the outside of the second reciprocating screw 512 through a ball nut pair. The connecting plate 504 is fixedly connected to the lower pressure plate 503. A transmission component is provided between the second reciprocating screw 512 and the first reciprocating screw 501.

[0042] The transmission assembly includes a first steering gear 505, a second support plate 506, and a transmission rod 508. The second support plate 506 is fixedly connected to the top of the feeding frame 2. The transmission rod 508 passes through the second support plate 506 and is rotatably connected to the second support plate 506. A first sprocket 507 is fixedly connected to one end of the transmission rod 508. A second sprocket 509 is rotatably connected to one side of the fixed plate 511. A limit block 510 is fixedly connected inside the second sprocket 509. The limit block 510 is set inside the sliding groove and is slidably connected to the first reciprocating screw 501. The first sprocket 507 and the second sprocket 509 are connected by a chain drive. A second steering gear 514 is fixedly connected to the other end of the transmission rod 508. The first steering gear 505 is meshed with the outside of the second steering gear 514. The first steering gear 505 is fixedly connected to the outside of the second reciprocating screw 512, which can coordinate the pressing of the material by the lower pressure plate 503 and the movement of the feeding frame 2.

[0043] Specifically, the external mud and water conveying hose is fixed to the feeding frames 3 on both sides of the feeding frame 2. The mud and water are injected into the feeding frame 2 and then conveyed into the separation and treatment box 1 through the feeding frame 2. The mud and water are filtered and separated by the filter plate 6. When the feeding frame 2 discharges material, the first motor 513 can be started. The output end of the first motor 513 drives the first reciprocating screw 501 to rotate. When the first motor 513 rotates, it drives the feeding frame 2 to move back and forth on the top of the separation and treatment box 1, so that the mud and water can be poured evenly onto the filter plate 6, thereby improving the filtration effect of the filter plate 6 and avoiding the material from being too concentrated, which would affect the filtration effect.

[0044] During the movement of the feeding frame 2, the sliding groove on the outer side of the first reciprocating screw 501 causes the limiting block 510 to drive the second sprocket 509 to rotate. When the second sprocket 509 rotates, it drives the first sprocket 507 to rotate via the chain. The rotation of the first sprocket 507 drives the fixedly connected transmission rod 508 to rotate. The rotation of the transmission rod 508 drives the fixedly connected second steering gear 514. The second steering gear 514 drives the meshing first steering gear 505, causing the second reciprocating screw 512 to drive the connecting plate 504 to push the lower pressure plate 503 to reciprocate up and down. Thus, the lower pressure plate 503 continuously squeezes the mud and water inside the feeding frame 2 to discharge the material, increasing the falling rate.

[0045] Please refer to it again. Figure 1 , Figure 2 , Figure 3 ,and Figure 4 The cleaning assembly includes a drive shaft 706, which passes through a movable plate 7 and is rotatably connected to the movable plate 7. One end of the drive shaft 706 is fixedly connected to a rotating disk 803, and a rotating shaft 805 is fixedly connected to one side of the rotating disk 803. A swing plate 804 is provided on one side of the rotating disk 803. A limit groove is opened inside the swing plate 804. The rotating shaft 805 extends into the swing plate 804. A positioning rod 806 is fixedly connected to one side of the movable plate 7. The positioning rod 806 passes through the swing plate 804 and is rotatably connected to the swing plate 804. One end of the positioning rod 806 is fixedly connected to a sector gear 807. A rack 802 is fixedly connected to the top of the connecting seat 801. The rack 802 meshes with the sector gear 807. The cleaning assembly also includes a third lead screw 702 and a limit rod 701. Both the third lead screw 702 and the limit rod 701 pass through the moving plate 7. The limit rod 701 is slidably connected to the moving plate 7 and fixedly connected to the separation processing box 1. The third lead screw 702 is connected to the moving plate 7 via a ball nut pair. The third lead screw 702 passes through the separation processing box 1 and is rotatably connected to the separation processing box 1. A second motor 703 is fixedly connected to the outside of the separation processing box 1. The output end of the second motor 703 is fixedly connected to the third lead screw 702. A third sprocket 705 is rotatably connected to the outer side of plate 7. A groove 704 is provided on the outer side of the third lead screw 702. A protrusion 708 is fixedly connected to the inner wall of the third sprocket 705. A fourth sprocket 707 is fixedly connected to the outer side of the drive shaft 706. The fourth sprocket 707 and the third sprocket 705 are connected by chain drive. The protrusion 708 is located inside the groove 704 on the outer side of the third lead screw 702 and is slidably connected to the third lead screw 702. The oscillation of the sector gear 807 can drive the meshing rack 802 to reciprocate.

[0046] Specifically, when the processed material falls onto the filter plate 6, the second motor 703 is activated, which drives the third lead screw 702 to rotate. The third lead screw 702 drives the moving plate 7 to move via a ball bearing nut pair. When the moving plate 7 moves, it also moves the fixedly connected cleaning side plate 8. A connecting seat 801 is fixedly connected to one side of the cleaning side plate 8, and multiple fixed cylinders 10 are fixedly connected to the bottom of the connecting seat 801. When the moving plate 7 moves, the chain drive of the third sprocket 705 and the fourth sprocket 707 causes the fourth sprocket 707 to drive the fixedly connected drive shaft 706 to rotate. When the drive shaft 706 rotates, it drives the fixedly connected rotating disk 803 to rotate. 03 drives the rotating shaft 805 to rotate. Since the rotating shaft 805 is in the groove opened in the swing plate 804, the swing plate 804 swings back and forth around the positioning rod 806. The sector gear 807 fixedly connected to one end of the swing plate 804 drives the meshing rack 802 to move back and forth. The connecting seat 801 also moves along with one end of the rack 802. Under the action of the spring 104 inside the fixed cylinder 10, the spring 104 pushes the fixed plate 106. The agitator plate 105 at the bottom of the sliding rod 103 contacts the top of the filter plate 6. As the agitator plate 105 moves along with the connecting seat 801, it agitates the mud and water, so that the mud and water are fully separated, and the mud and water separation effect is improved.

[0047] Please refer to it again. Figure 1 , Figure 2 , Figure 3 ,and Figure 4 An external gear ring 101 is rotatably connected to the bottom of the fixed cylinder 10. A cleaning brush 102 is fixedly connected to the bottom of the external gear ring 101. A connecting rack 107 is fixedly connected to the outer side of the cleaning side plate 8. The connecting rack 107 meshes with multiple external gear rings 101. Through the meshing of the external gear rings 101 and the connecting rack 107, the external gear rings 101 rotate, thereby causing the cleaning brush 102 to rotate and clean the filter plate 6. A fixed disk 106 is provided inside the fixed cylinder 10. A spring 104 is fixedly connected between the fixed disk 106 and the fixed cylinder 10. A sliding rod 103 is fixedly connected to the bottom of the fixed disk 106. The sliding rod 103 passes through the fixed cylinder 10 and is slidably connected to the fixed cylinder 10. A toggle plate 105 is fixedly connected to the bottom of the sliding rod 103. A baffle 901 is rotatably connected to one side of the collection frame 9, and an electric telescopic rod 903 is hinged to one side of the baffle 901. The electric telescopic rod 903 is rotatably connected to the top of the inside of the collection frame 9. A sliding box 902 is slidably connected inside the collection frame 9, which can collect and process the filtered mud.

[0048] The separation treatment box 1 is equipped with a drain pipe for drainage, and a control valve is installed on the outside of the drain pipe.

[0049] Specifically, when sludge needs to be treated, the first hydraulic telescopic rod 601 at the bottom of the filter plate 6 is activated. The first hydraulic telescopic rod 601 pushes the filter plate 6 upward, causing the filter plate 6 to push the actuating plate 105. The actuating plate 105 retracts into the cleaning brush 102, so that the cleaning brush 102 contacts the top of the filter plate 6, and the bottom of the cleaning side plate 8 contacts the top of the filter plate 6. Then, the swing plate 804 is activated to swing back and forth, and the sector gear 807 drives the connecting seat 801 to move back and forth. Because the outer gear ring 101 and the connecting rack are connected, the filter plate 6 is able to move back and forth. The 107 meshing connection causes the outer gear ring 101 to rotate, thereby cleaning the top of the filter plate 6 with the cleaning brush 102 and pushing the mud through the cleaning side plate 8. This activates the electric telescopic rod 903 inside the collection frame 9, which drives the baffle 901 to rotate and open the collection frame 9. At this time, the mud is pushed into the sliding box 902 for collection under the action of the cleaning side plate 8 and the cleaning brush 102, thus achieving the effect of cleaning the filter plate 6, avoiding manual cleaning, improving the filtration effect, and also ensuring that the mud and water are fully separated.
