Description

Technical Field

[0001] The present invention relates to the technical field of integrated pump stations, and in particular 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, resulting in damage to the pump body. Although this setting realizes the protection of 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, so manual cleaning is required regularly. There are also some enterprises that 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. Therefore, this application proposes an integrated pump station and a control method thereof. Summary of the Invention

[0011] 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 gas 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. A gas storage tank and a filtration tank are installed on the workbench. The gas storage tank is connected to the filtration tank through an intermediate pipe. A pressure relief valve is installed on the intermediate pipe. The gas supply pipe is connected to the filtration tank.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] The present invention also discloses a control method, which includes the following steps:

[0016] 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 a signal to the control box, and the electrical equipment inside the control box controls the sewage pump to work to discharge the sewage.

[0017] 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.

[0018] 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 and sewage, and start the sewage pump to discharge the mixed sludge and sewage to complete the cleaning of the sludge.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The rotation of the connecting pipe drives the rotation of the mesh cylinder, the connecting pipe, the first L-shaped pipe, the short pipe, and the second L-shaped pipe. The rotation of the second L-shaped pipe drives the rotation of the counterweight. Due to 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. Through the second L-shaped pipe and the counterweight, the sludge can be stirred, so that the sludge can be mixed with the sewage and the sludge can be agitated.

[0021] 2. Since the rotation speeds of the motors are different, the centrifugal forces received by the counterweights are also different, so that the rotation angle of the second L-shaped pipe can be controlled. When the second L-shaped pipe rotates 90° around the short pipe, at this time, the counterweight abuts 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 pipe will gradually increase and stabilize at a certain angle, so that the sludge storage seat can be fully stirred, and the sludge and sewage can be fully mixed, which is beneficial to the subsequent discharge.

[0022] 3. Air flows through the mesh cylinder into the connecting pipe, and then is discharged through the first L-shaped pipe, the short pipe, and the second L-shaped pipe. Cooperating with the second L-shaped pipe in different angular states, it can blow to different positions of the sludge storage seat. Since the air is sprayed onto the inner bottom of the sludge storage seat in a pulsed manner through the second L-shaped pipe, due to the large intensity of the pulse, the impact effect on the sludge is better.

[0023] 4. When the air is ejected through the movably arranged second L-shaped pipe, due to the resistance, the second L-shaped pipe will swing around the short pipe. It is similar to a magnet fixed on the table, 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 will swing around the short pipe, that is, the second L-shaped pipe will swing at a small angle, so as to further improve the efficiency of sludge cleaning.

[0024] 5. The filter residue filtered in the filter hopper can be sucked away and conveyed to the filter box through the middle pipe, realizing the cleaning of the filter hopper and the filter residue, and avoiding the drawback of the prior art that the filter frame needs to be lifted by a chain and manually cleaned regularly.

[0025] 6. The negative pressure can suck away and convey textile threads such as cotton threads that are filtered and not easily broken into the filter box, so that the textile threads such as cotton threads will not enter the sewage pump and wind around the shaft body, affecting the operation of the sewage pump.

[0026] 7. Since a single second L-shaped pipe is set as the sewage inlet pipe, the sewage pump can generate sufficient pressure at the outlet of the second L-shaped pipe during operation, so as to discharge the sludge and sewage mixture more powerfully.

[0027] 8. When air intermittently enters the upper part of the filter box through the middle pipe, since the air cannot quickly pass through the filter screen, it drives the filter screen to move and hit the stop bar, and the filter screen is separated from the filter material due to inertia, achieving self-cleaning.

[0028] In summary, the present invention can not only filter the leaves, cotton thread limiters, etc. crushed by the broken grille, but also clean and collect the filter material 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, achieving the cleaning of the sludge without manual participation and ensuring the stable operation of the pumping station.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0041] Referring to Figures 1 - 10 , an integrated pumping station includes a concrete installation base 1. A sludge accumulation base 2 is installed on the concrete installation base 1. An integral fiberglass reinforced plastic 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 reinforced plastic cylinder 3. A sewage pump 13 is installed inside the fiberglass reinforced plastic cylinder 3. The sewage pump 13 is installed inside the fiberglass reinforced plastic 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 reinforced plastic 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, and 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.

[0042] The inlet end and the discharge end of the sewage pump 13 are respectively installed with a rotary joint 14 and a delivery pipe 19. The delivery pipe 19 is connected to the drain pipe 4. The bottom of the rotary joint 14 is installed with a connecting pipe 24 that is driven to rotate, so that it can be connected to the sewage pump 13 and can also rotate itself; a workbench 9 is fixed on the inner wall of the fiberglass reinforced plastic cylinder 3. A motor 10 is installed on the workbench 9. The output end of the motor 10 is fixedly connected to 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 connecting pipe 24 can be rotated.

[0043] A net cylinder 38 is installed at the bottom of the connecting pipe 24. A first L-shaped pipe 16 is fixed to the bottom of the net 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 to 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 force 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.

[0044] A counterweight block 37 is fixed to the second L-shaped pipe 23. The counterweight block 37 is arranged close to the inner bottom of the sludge accumulation seat 2 and can be in a porous ring shape, that is, it can stir the sludge without affecting the sewage and sludge from entering the second L-shaped pipe 23.

[0045] When the connecting pipe 24 is driven to rotate, it can drive the first L-shaped pipe 16 to rotate. Due to the centrifugal force, the counterweight block 37 drives the second L-shaped pipe 23 to rotate around the short pipe 36 as an axis and forms 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 rotation speeds are different and tend to be in a stable state. Since the angles of the second L-shaped pipe 23 and the counterweight block 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.

[0046] The rotation of the second L-shaped pipe 23 in different states can stir different positions inside the sludge accumulation seat 2 to mix the sludge and water. A rotatable 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 to the inside of the sleeve 15 can be intermittently and pulsedly 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 when the sewage pump 13 works, the mixed liquid of the stirred sludge and water can be discharged.

[0047] 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 filtering hopper 39 is fixed to the bottom of the vertical rod 27. A conical platform is fixed in the middle of the filtering hopper 39. An annular shape is formed between the conical platform and the filtering hopper 39, and this annular shape is a net for filtering the sewage broken by the broken grille 12. It further includes a cleaning mechanism for cleaning the inside of the filtering 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.

[0048] It also includes a gas supply mechanism for supplying gas into the gas supply pipe 20. The gas supply mechanism includes a power shaft 26 rotatably installed at the bottom of the workbench 9. Second gears 28 are installed on the drive 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 to the bottom of the power shaft 26. A connecting rod 31 is sleeved on the L-shaped rod 29 and is rotatably arranged therewith. A piston cylinder 11 is installed in the fiberglass cylinder 3. The piston cylinder 11 is installed in the fiberglass cylinder 3 through a bracket.

[0049] An air inlet pipe 35 and an air outlet pipe 32 are installed on the piston cylinder 11. The air 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 into the air outlet pipe 32 through the piston cylinder 11; a second one-way valve 34 is installed on the air inlet pipe 35. The second one-way valve 34 only allows air to enter the piston cylinder 11 through the air inlet 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 tank 8 are installed on the workbench 9. There is a filter screen 40 in the filter tank 8. The filter screen 40 is made of stainless steel and slides in the filter tank 8. A spring 41 is fixed to the side of the filter screen 40 opposite to the intermediate pipe 17. The spring 41 is fixedly connected to the filter tank 8, and the filter tank 8 is fixed with a matching stop strip 42; when air intermittently enters the filter tank 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 strip 42, and the filter screen 40 is separated from the filter material due to inertia, realizing 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.

[0050] The intermediate pipe 17 and the gas supply pipe 20 are located on both sides of the filter screen 40; the air storage tank 7 and the filter tank 8 are connected through the intermediate pipe 17. A pressure relief valve 18 is installed on the intermediate pipe 17. The gas supply pipe 20 is connected to the filter tank 8. It should be noted that a solenoid valve is installed on the gas supply pipe 20. When the sewage pump 13 works, the solenoid valve is closed, so that air will not be delivered into the gas supply pipe 20 and the second L-shaped pipe 23, and the sewage transportation will not be affected. Correspondingly, a vertical pipe is installed on the air storage tank 7. There is a solenoid valve on the vertical pipe. When the sewage pump 13 works, the solenoid 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 solenoid valve on the gas supply pipe 20 is opened, and the solenoid valve on the vertical pipe is closed; among them, the vertical pipe and the solenoid valve are not shown in the figure, and the solenoid valve is controlled by the control box 5.

[0051] The upper end of the fiberglass cylinder 3 is provided with an inlet and outlet and a control box 5. A ladder installed in the fiberglass cylinder 3 is provided in the inlet and outlet. Workers can enter the fiberglass cylinder 3 through the ladder to clean the interior or perform maintenance work on the equipment.

[0052] In addition, a liquid level gauge is installed inside the fiberglass cylinder 3. The liquid level gauge, the motor 10, 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, transmit signals to the control box 5, and the electrical equipment inside the control box 5 controls the sewage pump 13 to work, so that 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 work simultaneously with the sewage pump 13.

[0053] In addition, a rain gauge is installed on the control box 5. Through the rain gauge, the size of the external rainwater can be known, so as to adaptively control the sewage pump 13 to work and discharge the sewage in the fiberglass cylinder 3, so as to better welcome the arrival of rainwater.

[0054] A pipeline can be installed on the fiberglass cylinder 3, which can convey sewage in different directions. A control valve is provided on this pipeline to control the flow of sewage and also play an anti-backflow effect.

[0055] The present invention also discloses a control method, which includes the following steps:

[0056] 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 inside the fiberglass cylinder 3, transmit signals to the control box 5, and the electrical equipment inside the control box 5 controls the sewage pump 13 to work to discharge the sewage;

[0057] S2, monitoring the rainfall to discharge sewage: Through the rain gauge, the size of the external rainwater can be known, so as to adaptively control the sewage pump 13 to work and discharge the sewage in the fiberglass cylinder 3;

[0058] S3, sludge cleaning: Start the motor 10 to drive the second L-shaped pipe 23 and the counterweight 37 to rotate at different speeds in different positions, mix the sludge and sewage, start the sewage pump 13 to discharge the mixed sludge and sewage, and complete the cleaning of the sludge.

[0059] 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, enter the sewage pump 13 through the rotary joint 14, and be pumped through the sewage pump 13 into the conveying pipe 19, and finally discharged through the drain pipe 4.

[0060] When it is necessary to clean the sludge in the sludge accumulation seat 2, it should be noted that there is still sewage remaining 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 two first gears 22, the connecting pipe 24 is driven to rotate. 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, so that the sludge can be mixed with the sewage.

[0061] Since the rotation speed of the motor 10 is different, the centrifugal force received by the counterweight 37 is also different, so that the rotation angle of the second L-shaped pipe 23 can be controlled. When the second L-shaped pipe 23 rotates 90° around the short pipe 36, at this time, the counterweight 37 abuts against the inner side wall of the sludge accumulation seat 2. 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 that the sludge accumulation seat 2 can be fully stirred, and the sludge and sewage can be fully mixed, which is beneficial to the subsequent discharge.

[0062] However, after all, the counterweight 37 does not abut against the inner bottom of the sludge accumulation seat 2, resulting in ineffective cleaning of the sludge deposited on the inner bottom; the rotation of the drive shaft 21 drives the second gear 28 to rotate. Through the transmission, the power shaft 26 is driven to rotate. The rotation of the power shaft 26 drives the L-shaped rod 29 to rotate. The rotation of the L-shaped rod 29 drives 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. The high-pressure air is quickly transported to the filter tank 8 through the intermediate pipe 17. The air pressure in the filter tank 8 increases and is discharged through the air supply pipe 20. The air flows through the net 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, impact the inner bottom of the sludge accumulation seat 2, and clean the sludge more effectively;

[0063] 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 towards the inner bottom of the sludge accumulation seat 2 in a pulsed manner through the second L-shaped pipe 23. Due to the high intensity of the pulse, the impact effect on the sludge is better.

[0064] 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 table, and another magnet is opposite to it with the same polarity. Due to the repulsive force, the upper magnet will shift to one side. Similarly, 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, thus further improving the effect of sludge cleaning.

[0065] The vertical rod 27 is realized through the transmission of the second gear 28. The rotation of the vertical rod 27 drives the filter hopper 39 to rotate. Therefore, the filter hopper 39 can filter the sewage at different positions, and can filter broken stones, leaves, cotton threads and other textile threads.

[0066] When the air is quickly discharged through the middle pipe 17, the air flow velocity at the upper end of the negative pressure pipe 25 is large and the pressure is small, and the pressure at the bottom of the negative pressure pipe 25 is large. There is a pressure difference between the two (Bernoulli principle). The air is transported to the middle pipe 17 through the negative pressure pipe 25. In this way, the filter residues filtered in the filter hopper 39 can be sucked away and transported to the filter box 8 through the middle pipe 17, realizing the cleaning of the filter hopper 39 and the filter residues, and avoiding the disadvantages of the prior art that the filter frame needs to be lifted by a chain and manually cleaned regularly.

[0067] Most importantly, the negative pressure can suck away and transport cotton threads and other textile threads that are filtered and not easily broken into the filter box 8. In this way, the cotton threads and other textile threads will not enter the sewage pump 13 and wind around the shaft body, affecting the operation of the sewage pump 13.

[0068] After a period of time, start the sewage pump 13, 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.

[0069] Since a single second L-shaped pipe 23 is set as the inlet pipe of the sewage, 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.

[0070] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
