Description

Technical Field

[0001] This utility model belongs to the field of sand making equipment, and specifically relates to a mud-sludge-water separation device. Background Technology

[0002] A large amount of mud and water is generated during construction activities. In order to improve the quality of sand, sedimentation is usually used in mud-water separation tanks to achieve the effect of mud-water separation. In the process of mud-water separation, flocculants and lime need to be mixed evenly with mud to achieve the ideal mud-water separation and stratification effect. However, it is difficult to achieve the requirement of uniform mixing by manual stirring.

[0003] To address the problem of difficulty in achieving uniform mixing of flocculants and lime with slurry through manual stirring, patent document CN201520321018.1 discloses a mud-water separation tank. This tank uses a spiral coil and a spiral conveyor belt in the slurry conveying pipe to ensure uniform mixing of slurry and flocculants, thus solving the problem of difficulty in achieving uniform mixing through manual stirring. A filter suction end is provided at the top of the tank, and a mud discharge port is opened at the bottom of the tank. After mud-water separation, the upper water is discharged through the filter suction end, and the lower mud is discharged outward through the mud discharge port. However, the position of the suction end of this device is not adjustable. The upper water below the suction end position can only be discharged from the mud discharge port at the bottom of the tank along with the mud, resulting in low mud-water separation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a mud-sludge-water separation device, thereby solving the problem that during the mud-water separation process, the upper layer of water below the water intake end can only be discharged from the mud discharge port at the bottom of the tank along with the mud, resulting in low mud-water separation efficiency.

[0005] To achieve the above objectives, this utility model provides a mud-sewage-water separation device, including a tank. The top of the tank has a feed inlet, the bottom of the tank has a first sludge discharge outlet, the top of the tank is equipped with a pumping device, the side of the tank has a drain outlet, and the upper part of the inner wall of the tank is equipped with a water level sensor.

[0006] The water pumping device includes a lifting assembly, a water suction hose, and a first water pump. The lifting assembly is installed at the top of the tank. One end of the water suction hose is fixed to the lifting assembly. The lifting assembly drives one end of the water suction hose to move closer to or away from the bottom of the tank. The other end of the water suction hose can extend out of the drain outlet and connect to the first water pump. Water from the upper layer is drawn by the first water pump through one end of the water suction hose.

[0007] Preferably, in the above technical solution, the lifting assembly includes an electric push rod and a bracket. One end of the electric push rod is fixed to the top of the tank body, the bracket is installed on the other end of the electric push rod, and one end of the water suction hose is fixed on the bracket and located above the water level sensor.

[0008] Preferably, in the above technical solution, a turbidity sensor is provided at one end of the water absorption hose.

[0009] Preferably, the above technical solution further includes an electromagnetic reversing valve, a settling tank, and a drain pipe. The electromagnetic reversing valve has a first inlet, a first outlet, and a second outlet. The first inlet is connected to the other end of the suction hose through the drain pipe. A clean water pipe is provided at the first outlet. The settling tank has a second inlet and a third outlet on both sides. The second outlet is connected to the second inlet through a sewage pipe. The third outlet is connected to the clean water pipe through a connecting pipe.

[0010] Preferably, in the above technical solution, the height of the second water inlet is lower than the height of the third water outlet.

[0011] Preferably, in the above technical solution, the bottom of the settling box has a second mud outlet.

[0012] Preferably, the above technical solution further includes a second water pump, wherein the first water pump is disposed between the tank and the electromagnetic reversing valve, and the second water pump is disposed between the settling tank and the clean water pipe through the connecting pipe.

[0013] Preferably, the above technical solution further includes an online turbidity meter, which is installed between the first water pump and the tank.

The first controller is communicatively connected to the second controller. The first controller is electrically connected to the water level sensor, the electromagnetic reversing valve, the second water pump, and the online turbidity meter, respectively. The second controller is electrically connected to the first water pump and the driver of the electric push rod, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The mud-sludge-water separation device of this utility model uses an electric push rod to drive one end of the suction hose into the water, and the first water pump draws the upper layer of water. An online turbidity meter monitors the turbidity of the water in the pipeline in real time. The clear water in the water layer is discharged from the clear water pipe. When the turbidity of the water in the pipeline reaches the second turbidity value set by the turbidity meter, the first controller controls the electromagnetic reversing valve to turn, and the turbid water in the water layer can flow into the settling tank through the sewage pipe to continue to settle. Then, the second water pump draws the settled clear water into the clear water pipe. The mud that settles in the settling tank can be discharged from the second mud discharge port. This solves the problem that the position of the suction end is not adjustable, and the mud close to the water layer will be discharged together with the water in the tank, resulting in low mud-water separation efficiency.

[0017] 2. A turbidity sensor is installed at one end of the water suction hose in this utility model. When the first controller receives a signal that the turbidity sensor has reached the set first turbidity value, it indicates that one end of the water suction hose has touched the soil layer. The second controller controls the first water pump to stop pumping water and drives the other end of the electric push rod to retract, thereby resetting one end of the water suction hose. The device has a high degree of automation.

[0018] 3. The speed at which the other end of the electric push rod extends in this utility model can be controlled by a second controller to ensure that the water suction hose can pump out all the water in the tank, thereby helping to improve the efficiency of mud-water separation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0028] Figures 1-4 As shown, the mud-sludge-water separation device in this embodiment includes: a tank 1, an online turbidity meter 2, a first water pump 3, a drain pipe 4, a first water inlet 5, an electromagnetic reversing valve 6, a clean water pipe 7, a settling tank 8, a third water outlet 9, a connecting pipe 10, a second water pump 11, a feed inlet 12, a drain outlet 13, a first water outlet 14, a second water outlet 15, a sewage discharge pipe 16, an electric push rod 17, a turbidity sensor 18, a water suction hose 19, a water level sensor 20, a first sludge discharge outlet 21, and a support 22.

[0029] Continue to refer Figures 1-4 The tank 1 has a feed inlet 12 at the top, through which slurry enters. The tank 1 also has a first row of slurry outlets 21 at the bottom. After the slurry settles and the mud and water separate within the tank 1, the upper layer of the tank 1 is a water layer, and the lower layer is a mud layer. The mud is discharged through the first row of slurry outlets 21. A water level sensor 20 is installed on the inner wall of the tank 1 to measure the slurry height. A first controller is electrically connected to the water level sensor 20 and sets a height value for it. When the water level sensor 20 detects that the slurry height has reached the set value, the feed inlet 12 stops feeding slurry. A pumping device is installed at the top of the tank 1 to extract the upper water layer after the slurry-water separation.

[0030] The pumping device includes an electric push rod 17, a bracket 22, a suction hose 19, and a first pump 3. One end of the electric push rod 17 is fixed to the top of the tank 1, and the bracket 22 is installed on the other end of the electric push rod 17. One end of the suction hose 19 is fixed to the bracket 22 and located above the water level sensor 20 to prevent the end of the suction hose 19 from accidentally sucking in untreated sludge. A drain outlet 13 is opened on the side of the tank 1. The other end of the suction hose 19 extends out of the drain outlet 13 and is connected to the first pump 3. A second controller is electrically connected to the driver of the electric push rod 17 and the first pump 3. The second controller starts the electric push rod 17 and drives one end of the suction hose 19 to move towards the water layer and pump water through the first pump 3. The second controller controls the speed at which the other end of the electric push rod 17 extends to limit the speed at which one end of the suction hose 19 moves, so that the suction hose 19 extends into the water by one to two centimeters, and pumps water out of the tank 1 as much as possible.

[0031] To prevent one end of the suction hose 19 from touching the soil layer, a turbidity sensor 18 is installed at one end of the suction hose 19 in this embodiment. The first controller is electrically connected to the turbidity sensor 18, and the first controller is communicatively connected to the second controller. The turbidity sensor 18 is existing technology and can distinguish between the soil layer and the water layer. A first turbidity value is first set for the turbidity sensor 18. When the first controller receives a signal from the turbidity sensor 18 indicating that the first turbidity value has been reached, it means that one end of the suction hose 19 has touched the soil layer. After receiving the signal from the first controller indicating that the soil layer has been detected, the second controller controls the first water pump 3 to stop pumping water and drives the other end of the electric push rod 17 to retract, thereby resetting one end of the suction hose 19.

[0032] The water in the water layer is divided into clear water and turbid water, which are distinguished by an online turbidity meter 2. The online turbidity meter 2 is installed between the first water pump 3 and the tank 1 and is electrically connected to the first controller. During the water pumping process of the suction hose 19, the online turbidity meter 2 will detect the turbidity of the water in the pipeline in real time and set a second turbidity value for the online turbidity meter 2. When the second turbidity value of the online turbidity meter 2 is reached, it indicates that the water flowing into the pipeline is turbid water.

[0033] In this embodiment, the second controller is electrically connected to the electromagnetic reversing valve 6. When the second controller receives a signal from the first controller that the second turbidity value has been reached, the second controller controls the electromagnetic reversing valve 6 to turn, ensuring that the clean water and turbid water flow into different pipelines respectively. The electromagnetic reversing valve 6 has a first inlet 5, a first outlet 14, and a second outlet 15. The first inlet 5 is connected to the other end of the suction hose 19 via a drain pipe 4. At this time, the first water pump 3 is located between the tank 1 and the electromagnetic reversing valve 6. A clear water pipe 7 is installed at the first outlet 14. When the second turbidity value is not reached, the water in the drain pipe 4 is clear water, which can flow into the clear water pipe 7 through the first outlet 14. The settling tank 8 has a second inlet and a third outlet 9 on both sides. The second outlet 15 of the electromagnetic reversing valve 6 is connected to the second inlet of the settling tank 8 via a drain pipe 16. When the second controller receives a signal from the online turbidity meter 2 that turbid water has been detected, the electromagnetic reversing valve 6 turns to close the first outlet 14 and open the second outlet 15. The turbid water can flow into the settling tank 8 through the drain pipe 16 to continue settling. The third outlet 9 is connected to... Pipe 10 is connected to the clean water pipe 7. The second water pump 11 is set between the settling tank 8 and the clean water pipe 7 through the connecting pipe 10. The height of the second water inlet of the settling tank 8 is lower than the height of the third water outlet 9. After sedimentation in the settling tank 8, the turbid water separates into a water layer and a mud layer. The first controller is electrically connected to the second water pump 11 and sets a time value for the second water pump 11. After the electromagnetic reversing valve 6 turns and the second water outlet 15 is opened, the timer starts. After the set time value is reached, the second controller starts the second water pump 11 to draw clean water from the settling tank 8 and flow into the clean water pipe 7 through the connecting pipe 10. This not only improves the efficiency of mud-water separation in the tank 1, but also avoids the waste of water resources. The bottom of the settling tank 8 has a second mud outlet, and the bottom of the settling tank 8 is inverted cone-shaped, which facilitates the discharge of mud in the settling tank 8 through the second mud outlet and avoids the accumulation of mud in the settling tank 8.

[0034] In summary, in this embodiment, the electric push rod 17 drives one end of the water suction hose 19 into the water, and the first water pump 3 draws out the upper layer of water. The online turbidity meter 2 monitors the turbidity of the water in the pipeline in real time. The clean water is discharged through the clean water pipe 7. When the turbidity of the water reaches the second turbidity value set by the online turbidity meter 2, the first controller controls the electromagnetic reversing valve 6 to turn, so that the turbid water can flow into the settling tank 8 through the drain pipe 16 to continue to settle. Then, the second water pump 11 draws the settled clean water into the clean water pipe 7. The mud that settles in the settling tank 8 can be discharged from the second mud discharge port. This solves the problem that the position of the water suction end is not adjustable, and the mud close to the water layer will be discharged together with the water in the tank 1, resulting in low mud-water separation efficiency.
