Description

Technical Field

[0001] The present invention relates to the technical field of integrated pump stations, and particularly relates to an integrated pump station and a control method thereof. Background Art

[0002] An integrated prefabricated pump station is a lifting equipment for sewage, rainwater, drinking water, and wastewater, which is a pressurized pump station assembled by a factory and transported to the site for installation.

[0003] When external sewage enters the pump station, it needs to be crushed by a crushing grid so that leaves, stones, etc. will not enter the submersible pump or sewage pump, causing damage to the pump body. Although this setting protects the pump body, due to road surface rainwater, etc. entering the pump station, as well as crushed impurities, there are more sludge and debris in the pump station. To ensure the stability of the pump body during use, the pump body is fixedly installed in the pump station, and the inlet end is fixedly arranged. This results in only the sludge near the inlet end being able to be discharged together with the sewage, while the sludge in other places cannot be effectively cleaned. Therefore, manual cleaning needs to be carried out regularly. Some enterprises also install air pipes near the pump body and supply air into the air pipes through an external air pump to blow the sludge, so that it is mixed with the sewage and discharged through the pump body to achieve the cleaning of the sludge. However, the layout position of the air pipes is limited, and the treatment effect on the sludge is not ideal. For this reason, the present application proposes an integrated pump station and a control method thereof. Summary of the Invention

[0010] Preferably, it further includes a gas supply mechanism for supplying gas into the gas supply pipe. The gas supply mechanism includes a power shaft rotatably installed at the bottom of the workbench. Second gears are installed on the drive shaft, the vertical rod, and the power shaft, and the three second gears are meshed with each other. An L-shaped rod is fixed to the bottom of the power shaft. A connecting rod is sleeved on the L-shaped rod and is rotatably arranged therewith. A piston cylinder is installed inside the fiberglass cylinder body. An air inlet pipe and an air outlet pipe are installed on the piston cylinder. The air outlet pipe is connected to the air storage tank and is equipped with a first one-way valve. A second one-way valve is installed on the air inlet pipe. A moving piston that reciprocates is slidably connected inside the piston cylinder. The connecting rod is hinged to the moving piston. An air storage tank and a filter tank are installed on the workbench. The air storage tank is connected to the filter tank through an intermediate pipe. A pressure relief valve is installed on the intermediate pipe. The gas supply pipe is connected to the filter tank.

[0011] Preferably, it further includes a cleaning mechanism for cleaning the inside of the filter hopper. The cleaning mechanism includes a negative pressure pipe installed at the bottom of the intermediate pipe, and the negative pressure pipe is arranged opposite to the annular shape.

[0012] Preferably, an inlet and outlet is provided at the upper end of the fiberglass cylinder body, and a ladder installed inside the fiberglass cylinder body is provided in the inlet and outlet.

[0013] Preferably, a liquid level gauge is installed inside the fiberglass cylinder body, and the liquid level gauge, the motor, and the sewage pump are connected to the control box.

[0014] The present invention also discloses a control method, including the following steps: S1, monitoring the liquid level to discharge sewage: Sewage enters the fiberglass cylinder body through the water inlet pipe, causing the liquid level to rise. The liquid level gauge can monitor the liquid level inside the fiberglass cylinder body, transmit the signal to the control box, and the electrical equipment inside the control box controls the sewage pump to work to discharge the sewage. S2, monitoring the rainfall to discharge sewage: The size of the external rainwater can be known through the rain gauge, so as to adaptively control the sewage pump to work and discharge the sewage inside the fiberglass cylinder body. S3, sludge cleaning: Start the motor to drive the second L-shaped pipe and the counterweight to rotate at different speeds at different positions, mix the sludge with the sewage, and start the sewage pump to discharge the mixed sludge and sewage to complete the cleaning of the sludge.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The rotation of the connecting pipe drives the net cylinder, the connecting pipe, the first L-shaped pipe, the short pipe, and the second L-shaped pipe to rotate. The rotation of the second L-shaped pipe drives the counterweight to rotate. Due to the centrifugal force, the heavier end of the second L-shaped pipe rotates to one side, that is, the second L-shaped pipe rotates around the short pipe. The sludge can be stirred through the second L-shaped pipe and the counterweight, so that the sludge can be mixed with the sewage and the sludge is agitated.

[0016] 2. Due to the different rotation speeds of the motor, the centrifugal force exerted on the counterweight is also different, which can control the rotation angle of the second L-shaped tube. When the second L-shaped tube rotates 90° with the short tube as the axis, the counterweight at this time is against the inner wall of the sludge storage seat. Therefore, when the motor gradually increases the speed and stabilizes at a certain speed, the rotation angle of the second L-shaped tube will gradually increase and tend to stabilize at a certain angle, so that the sludge storage seat can be fully stirred, so that the sludge and sewage can be fully mixed to facilitate subsequent discharge.

[0017] 3. The air flows through the mesh tube into the connecting tube, and then is discharged through the first L-shaped tube, the short tube, and the second L-shaped tube. With the second L-shaped tube at different angles, the air can be blown to different positions of the sludge storage seat. Since the air is sprayed to the bottom of the sludge storage seat in a pulsed manner through the second L-shaped tube, the pulse intensity is large, so the impact effect on the sludge is better.

[0018] 4. When the air is ejected through the movable second L-shaped tube, the resistance will cause the second L-shaped tube to swing around the short tube as the axis, which is similar to a magnet fixed on a desktop and another magnet with the same polarity opposite to it. Due to the repulsive force, the upper magnet will shift to one side. Similar to the above, the second L-shaped tube will swing around the short tube as the axis, that is, the second L-shaped tube will swing at a small angle, thereby further improving the sludge cleaning effect.

[0019] 5. The filtered material in the filter bucket can be sucked away and transported to the filter box through the intermediate pipe, so as to clean the filter bucket and the filtered material, thus avoiding the disadvantage of the prior art that the filter frame needs to be lifted up by a chain for manual regular cleaning.

[0020] 6. Negative pressure can absorb the filtered and not easily broken cotton threads and other textile threads and transport them to the filter box, so that cotton threads and other textile threads will not enter the sewage pump and cause them to be entangled on the shaft, affecting the operation of the sewage pump.

[0021] 7. Since a single second L-shaped pipe is provided as the sewage inlet pipe, the sewage pump can generate sufficient pressure at the outlet of the second L-shaped pipe, thereby discharging the sludge and sewage mixture more effectively.

[0022] 8. When the air intermittently enters the filter box through the middle pipe, the air cannot quickly pass through the filter, thereby driving the filter to move and hit the baffle. Due to inertia, the filter is separated from the filter material, achieving self-cleaning.

[0023] In summary, the present invention can not only filter the leaves, cotton threads, etc. crushed by the crushing grille, but also clean and collect the filtered substances to ensure the stability of the pump body. It can also effectively mix the sludge with the sewage and cooperate with the sludge pump to discharge the sludge, realizing the cleaning of the sludge without manual participation and ensuring the stable operation of the pumping station.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Referring to Figures 1 - 10 , an integrated pumping station includes a concrete mounting base 1. A sludge accumulation base 2 is installed on the concrete mounting base 1. A one-piece fiberglass cylinder 3 is fixed on the sludge accumulation base 2. A water inlet pipe 6 and a drain pipe 4 are installed on the fiberglass cylinder 3. A sewage pump 13 is installed inside the fiberglass cylinder 3. The sewage pump 13 is installed inside the fiberglass cylinder 3 through a bracket, and the bracket is not shown in the figure. Among them, an explanation is made for the water inlet pipe 6: A crushing grille 12 is installed on the inner wall of the fiberglass cylinder 3. The crushing grille 12 can crush leaves, stones, etc. in the sewage to prevent them from entering the sewage pump 13 and causing damage to it; the crushing grille 12 is connected to the water inlet pipe 6. A drain port is provided at the bottom of the crushing grille 12, and the drain port is arranged opposite to one side of the filter hopper 39.

[0028] A rotary joint 14 and a delivery pipe 19 are respectively installed at the inlet end and the discharge end of the sewage pump 13. The delivery pipe 19 is connected to the drain pipe 4. A connecting pipe 24 driven to rotate is installed at the bottom of the rotary joint 14. In this way, connection with the sewage pump 13 can be achieved, and its own rotation can also be achieved; A workbench 9 is fixed on the inner wall of the fiberglass cylinder 3. A motor 10 is installed on the workbench 9. The output end of the motor 10 is fixedly connected with a drive shaft 21. First gears 22 are installed on both the drive shaft 21 and the connecting pipe 24. The two first gears 22 are meshed with each other. Therefore, when the motor 10 works to drive the drive shaft 21 to rotate, through the transmission of the two first gears 22, the rotation of the connecting pipe 24 can be achieved.

[0029] A mesh cylinder 38 is installed at the bottom of the connecting pipe 24. A first L-shaped pipe 16 is fixed at the bottom of the mesh cylinder 38. The bottom of the end of the first L-shaped pipe 16 is rotatably connected to a communicating short pipe 36. A second L-shaped pipe 23 is fixed at the bottom of the short pipe 36. A torsion spring is installed between the first L-shaped pipe 16 and the second L-shaped pipe 23. Under the torsion of the torsion spring, the first L-shaped pipe 16 and the second L-shaped pipe 23 are parallel in the horizontal direction, that is, the initial position of the second L-shaped pipe 23 at this time.

[0030] A counterweight 37 is fixed on the second L-shaped pipe 23. The counterweight 37 is arranged close to the inner bottom of the sludge accumulation base 2 and can be a porous ring shape, that is to say, it can stir the sludge without affecting the entry of sewage and sludge into the second L-shaped pipe 23.

[0031] The connecting pipe 24 is driven to rotate, which can drive the first L-shaped pipe 16 to rotate. Due to the centrifugal force, the counterweight 37 drives the second L-shaped pipe 23 to rotate around the short pipe 36 as the axis and form an angle with the first L-shaped pipe 16 (observing the angle formed between the first L-shaped pipe 16 and the second L-shaped pipe 23 from above). The angles between the second L-shaped pipe 23 and the first L-shaped pipe 16 at different rotational speeds are different and tend to be stable. Since the angles of the second L-shaped pipe 23 and the counterweight 37 are different, the sludge at different positions of the sludge accumulation seat 2 can be stirred, and the sludge can be cleaned more effectively.

[0032] The rotation of the second L-shaped pipe 23 in different states can stir different positions in the sludge accumulation seat 2 to mix the sludge and water. A rotatably arranged sleeve 15 is sleeved on the connecting pipe 24, the net cylinder 38, and the first L-shaped pipe 16. An air supply pipe 20 is installed on the sleeve 15, and a check valve is installed on the air supply pipe 20 to prevent sewage backflow; the intermittent air supply from the air supply pipe 20 into the sleeve 15 can be intermittently and pulsatively ejected through the second L-shaped pipe 23 and blown towards the sludge. Cooperating with the rotating second L-shaped pipe 23 can stir the sludge and water, and the sewage pump 13 can discharge the stirred mixture of sludge and water.

[0033] It further includes a filtering mechanism. The filtering mechanism includes a vertical rod 27 rotatably installed at the bottom of the workbench 9 and connected to the driving shaft 21. A filter hopper 39 is fixed at the bottom of the vertical rod 27. A conical platform is fixed in the middle of the filter hopper 39. An annular shape is formed between the conical platform and the filter hopper 39. The annular shape is net-shaped for filtering the sewage broken by the broken grille 12. It further includes a cleaning mechanism for cleaning the inside of the filter hopper 39. The cleaning mechanism includes a negative pressure pipe 25 installed at the bottom of the middle pipe 17, and the negative pressure pipe 25 is arranged opposite to the annular shape.

[0034] It further includes an air supply mechanism for supplying air into the air supply pipe 20. The air supply mechanism includes a power shaft 26 rotatably installed at the bottom of the workbench 9. Second gears 28 are installed on the driving shaft 21, the vertical rod 27, and the power shaft 26. The three second gears 28 are meshed with each other. An L-shaped rod 29 is fixed at the bottom of the power shaft 26. A connecting rod 31 is sleeved on the L-shaped rod 29 and is rotatably arranged with it. A piston cylinder 11 is installed in the fiberglass cylinder 3, and the piston cylinder 11 is installed in the fiberglass cylinder 3 through a bracket.

[0035] An intake pipe 35 and an outlet pipe 32 are installed on the piston cylinder 11. The outlet pipe 32 is connected to the air storage tank 7 and is equipped with a first one-way valve 33. The first one-way valve 33 only allows air to flow from the piston cylinder 11 into the outlet pipe 32; a second one-way valve 34 is installed on the intake pipe 35. The second one-way valve 34 only allows air to enter the piston cylinder 11 through the intake pipe 35; a reciprocating moving piston 30 is slidably connected in the piston cylinder 11. The connecting rod 31 is hinged to the moving piston 30. An air storage tank 7 and a filter box 8 are installed on the workbench 9. There is a filter screen 40 in the filter box 8. The filter screen 40 is made of stainless steel and slides in the filter box 8. A spring 41 is fixed on the side of the filter screen 40 opposite to the intermediate pipe 17. The spring 41 is fixedly connected to the filter box 8, and the filter box 8 is fixed with a matching stop bar 42; when air intermittently enters the filter box 8 through the intermediate pipe 17, since the air cannot quickly pass through the filter screen 40, the filter screen 40 is driven to move and hit the stop bar 42, and the filter screen 40 is separated from the filter material due to inertia to achieve self-cleaning; then the air passes through the filter screen 40, and the filter screen 40 is reset under the action of the spring 41.

[0036] The intermediate pipe 17 and the air supply pipe 20 are located on both sides of the filter screen 40; the air storage tank 7 is connected to the filter box 8 through the intermediate pipe 17. A pressure relief valve 18 is installed on the intermediate pipe 17. The air supply pipe 20 is connected to the filter box 8. It should be noted that an electromagnetic valve is installed on the air supply pipe 20. When the sewage pump 13 works, the electromagnetic valve is closed, so that air will not be delivered into the air supply pipe 20 and the second L-shaped pipe 23, which will not affect the conveyance of sewage. Correspondingly, a vertical pipe is installed on the air storage tank 7, and an electromagnetic valve is installed on the vertical pipe. When the sewage pump 13 works, the electromagnetic valve is opened, so that the air in the air storage tank 7 can be discharged; on the contrary, when cleaning the sludge with air, the electromagnetic valve on the air supply pipe 20 is opened, and the electromagnetic valve on the vertical pipe is closed; among them, the vertical pipe and the electromagnetic valve are not shown in the figure, and the electromagnetic valve is controlled by the control box 5.

[0037] An inlet and outlet and a control box 5 are provided at the upper end of the fiberglass cylinder 3. A ladder installed inside the fiberglass cylinder 3 is provided in the inlet and outlet. Workers can enter the fiberglass cylinder 3 through the ladder to clean the inside or perform maintenance work on the equipment.

[0038] In addition, a liquid level gauge is installed inside the fiberglass cylinder 3. The liquid level gauge, the motor 10, and the sewage pump 13 are connected to the control box 5. The liquid level gauge can monitor the liquid level inside the fiberglass cylinder 3 and transmit the signal to the control box 5. The electrical equipment inside the control box 5 controls the sewage pump 13 to work, and the sewage can be discharged. The control box 5 can regularly control the motor 10 to work to discharge the sludge in the sludge accumulation seat 2, or can work simultaneously with the sewage pump 13.

[0039] In addition, a rain gauge is installed on the control box 5. The size of external rainwater can be obtained through the rain gauge, so as to adaptively control the operation of the sewage pump 13, and the sewage in the fiberglass cylinder 3 can be discharged to better welcome the arrival of rainwater.

[0040] A pipeline can be installed on the fiberglass cylinder 3 to convey sewage in different directions. A control valve is provided on this pipeline to control the flow of sewage and also achieve the effect of preventing backflow.

[0041] The present invention also discloses a control method, including the following steps: S1, Monitoring the liquid level to discharge sewage: The sewage enters the fiberglass cylinder 3 through the water inlet pipe 6, causing the liquid level to rise. The liquid level gauge can monitor the liquid level in the fiberglass cylinder 3, transmit the signal to the control box 5, and the electrical equipment inside the control box 5 controls the sewage pump 13 to work and discharge the sewage. S2, Monitoring the rainfall to discharge sewage: The size of external rainwater can be obtained through the rain gauge, so as to adaptively control the operation of the sewage pump 13 and discharge the sewage in the fiberglass cylinder 3. S3, Sludge cleaning: Start the motor 10 to drive the second L-shaped pipe 23 and the counterweight 37 to rotate at different speeds at different positions, mix the sludge with the sewage, and start the sewage pump 13 to discharge the mixed sludge and sewage to complete the cleaning of the sludge.

[0042] When the present invention is in use, on sunny or rainy days, the sewage is discharged, and the sewage pump 13 works. The sewage can be conveyed through the second L-shaped pipe 23 and the short pipe 36 into the first L-shaped pipe 16, and then conveyed into the connecting pipe 24. It enters the sewage pump 13 through the rotary joint 14, is pumped by the sewage pump 13 and conveyed into the conveying pipe 19, and finally discharged through the drain pipe 4.

[0043] When it is necessary to clean the sludge in the sludge accumulation seat 2, it should be noted that there is still sewage above the sludge; start the motor 10 to drive the drive shaft 21 to rotate. The rotation of the drive shaft 21 drives the first gear 22 to rotate. Through the transmission of the two first gears 22, the connecting pipe 24 rotates. The rotation of the connecting pipe 24 drives the net cylinder 38, the connecting pipe 24, the first L-shaped pipe 16, the short pipe 36 and the second L-shaped pipe 23 to rotate. The rotation of the second L-shaped pipe 23 drives the counterweight 37 to rotate. Due to the centrifugal force, the heavier end of the second L-shaped pipe 23 rotates to one side, that is, the second L-shaped pipe 23 rotates around the short pipe 36. The sludge can be stirred through the second L-shaped pipe 23 and the counterweight 37 to make the sludge mix with the sewage.

[0044] Since the rotating speeds of the motor 10 are different, the centrifugal forces received by the counterweight 37 are also different, thereby controlling the rotation angle of the second L-shaped pipe 23. When the second L-shaped pipe 23 rotates 90° around the short pipe 36, the counterweight 37 abuts against the inner side wall of the sludge accumulation seat 2 at this time. Therefore, when the motor 10 gradually increases the speed and stabilizes at a certain speed, the rotation angle of the second L-shaped pipe 23 will gradually increase and stabilize at a certain angle, so as to fully stir the sludge accumulation seat 2, and thus the sludge and sewage can be fully mixed, which is beneficial to the subsequent discharge.

[0045] However, after all, the counterweight 37 does not abut against the inner bottom of the sludge accumulation seat 2, resulting in the inability to effectively clean the sludge deposited on the inner bottom; the driving shaft 21 rotates to drive the second gear 28 to rotate, and through transmission, the power shaft 26 rotates. The power shaft 26 rotates to drive the L-shaped rod 29 to rotate, and the L-shaped rod 29 rotates to drive the connecting rod 31 and the moving piston 30 to reciprocate (simple crank movement). When the moving piston 30 moves close to the motor 10, air can enter the piston cylinder 11 through the air inlet pipe 35. When the moving piston 30 moves away from the motor 10, the air inside can be squeezed into the air outlet pipe 32. Finally, it is transported to the air storage tank 7 through the air outlet pipe 32. As the motor 10 continues to work, air will be intermittently transported into the air storage tank 7. When the air pressure in the air storage tank 7 is greater than the threshold value of the pressure relief valve 18, the pressure relief valve 18 opens, and the high-pressure air is quickly transported to the filter box 8 through the intermediate pipe 17. The air pressure in the filter box 8 increases and is discharged through the air supply pipe 20. The air flows through the mesh cylinder 38 into the connecting pipe 24, and then is discharged through the first L-shaped pipe 16, the short pipe 36, and the second L-shaped pipe 23. Cooperating with the second L-shaped pipe 23 in different angular states, in this way, it can blow to different positions of the sludge accumulation seat 2, and can impact the inner bottom of the sludge accumulation seat 2, and can clean the sludge more effectively; When the air pressure in the air storage tank 7 is greater than the threshold value of the pressure relief valve 18, repeat the above. In this way, the air is sprayed onto the inner bottom of the sludge accumulation seat 2 in a pulsed manner through the second L-shaped pipe 23. Due to the large intensity of the pulse, the impact effect on the sludge is better.

[0046] When the air is ejected through the movably arranged second L-shaped pipe 23, due to the resistance, the second L-shaped pipe 23 will swing around the short pipe 36. It is similar to a magnet fixed on the tabletop, and another magnet is opposite to it with the same polarity. Due to the repulsive force, the upper magnet will shift to one side. Similar to the above, the second L-shaped pipe 23 will swing around the short pipe 36, that is to say, the second L-shaped pipe 23 will swing at a small angle, so as to further improve the effect of cleaning the sludge.

[0047] The vertical rod 27 is driven by the transmission of the second gear 28. The rotation of the vertical rod 27 drives the rotation of the filter hopper 39. Therefore, the filter hopper 39 can filter sewage at different positions, and can filter broken stones, leaves, and textile threads such as cotton threads. When air is quickly discharged through the middle pipe 17, the air flow rate at the upper end of the negative pressure pipe 25 is large and the pressure is small, while the pressure at the bottom of the negative pressure pipe 25 is large. A pressure difference is generated between the two (Bernoulli's principle). Air is transported through the negative pressure pipe 25 into the middle pipe 17. In this way, the filter residues filtered in the filter hopper 39 can be sucked away and transported through the middle pipe 17 into the filter box 8, realizing the cleaning of the filter hopper 39 and the filter residues, and avoiding the drawback of the prior art that the filter frame needs to be lifted by a chain and manually cleaned regularly.

[0048] Most importantly, the negative pressure can suck away textile threads such as cotton threads that are filtered and not easily broken and transport them into the filter box 8. In this way, the textile threads such as cotton threads will not enter the sewage pump 13 and wind around the shaft body, affecting the operation of the sewage pump 13.

[0049] After a period of time, the sewage pump 13 is started, and the treated sludge and sewage mixture can be discharged, realizing the treatment of the sludge in the sludge accumulation seat 2, and the treatment effect is good.

[0050] Since a single second L-shaped pipe 23 is provided as the sewage inlet pipe, the operation of the sewage pump 13 can generate sufficient negative pressure at the outlet of the second L-shaped pipe 23, so as to more powerfully discharge the sludge and sewage mixture.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
