Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic wastewater overflow regulating device. Background Technology

[0002] To achieve the recycling of glass wastewater, glass wastewater treatment equipment is installed during the glass production process. After passing through equalization tanks, coagulation reaction tanks, and sedimentation tanks, the glass wastewater is poured into clear water tanks for use.

[0003] In related technologies, when there is sufficient glass wastewater but drainage is not timely, manual adjustment of the drainage volume is required to increase the drainage volume and prevent wastewater overflow. This reduces the efficiency of glass wastewater treatment and is not conducive to the orderly treatment of glass wastewater. Moreover, when treating wastewater with sufficient volume, it is easy for glass wastewater to overflow uncontrollably, and untreated wastewater can easily cause environmental pollution. Utility Model Content

[0004] The main purpose of this invention is to propose an automatic wastewater overflow regulation device, which aims to automatically balance the inflow and outflow of wastewater when encountering large flow rates of wastewater, thereby avoiding environmental pollution caused by wastewater overflow and ensuring wastewater treatment efficiency.

[0005] To achieve the above objectives, the present invention proposes an automatic wastewater overflow regulating device, comprising:

[0006] The regulating tank is provided with an inlet;

[0007] A clean water tank, wherein the clean water tank is provided with a discharge port;

[0008] A sedimentation mechanism is provided between the equalization tank and the clear water tank, and is connected to both the equalization tank and the clear water tank.

[0009] The regulating mechanism includes a high liquid level switch sensor, a low liquid level switch sensor, and a pneumatic ball valve. The high liquid level switch sensor is located at the inlet, and the low liquid level switch sensor is located below the high liquid level switch sensor and has a height difference with it. The pneumatic ball valve is located at the outlet and is used to open or close the outlet.

[0010] In one embodiment, the distance between the top wall of the inlet and the high liquid level switch sensor is in the range of 200-300 mm.

[0011] In one embodiment, the height difference is 200 mm.

[0012] In one embodiment, the wastewater overflow automatic regulating device further includes a control device, which is electrically connected to both the high liquid level switch sensor and the low liquid level switch sensor, and is also electrically connected to the pneumatic ball valve.

[0013] In one embodiment, the control device includes a power supply unit, and the high liquid level switch sensor, the low liquid level switch sensor, and the pneumatic ball valve are all connected to the power supply unit.

[0014] In one embodiment, the control device further includes a switching assembly, which is electrically connected to the pneumatic ball valve, and both the high liquid level switch sensor and the low liquid level switch sensor are electrically connected to the switching assembly.

[0015] In one embodiment, the sedimentation mechanism further includes a plurality of sedimentation tanks, which are spaced apart. Each of the sedimentation tanks has a liquid outlet at its top, and each of the liquid outlets is connected to the clear water tank. Furthermore, each of the sedimentation tanks is connected to the equalization tank.

[0016] In one embodiment, the sedimentation mechanism further includes a sludge tank, and the bottom of each of the plurality of sedimentation tanks is provided with a sludge outlet, and the plurality of sludge outlets are connected to the sludge tank.

[0017] In one embodiment, the sedimentation mechanism further includes a reaction tank, and a plurality of sedimentation tanks are connected to the reaction tank, and the reaction tank is connected to the equalization tank.

[0018] In one embodiment, a plurality of transmission pipes are connected in parallel between the reaction tank and the regulating tank, and regulating valves are provided in the transmission pipes.

[0019] The technical solution of this utility model involves installing a high-level switch sensor and a low-level switch sensor at the inlet of the wastewater treatment system, with the planes of the high-level and low-level switch sensors perpendicular to the liquid surface. This allows for the detection of the water volume at the inlet. When the water volume at the inlet is excessive, a pneumatic ball valve is opened to quickly drain the clean water tank. The pneumatic ball valve automatically closes when the water level at the inlet is lower than the plane of the low-level switch sensor. This ensures that the start-up ball valve in the wastewater treatment system automatically opens to drain water even with large inflows, guaranteeing automated treatment of the wastewater under such conditions, preventing uncontrolled overflow of wastewater, and improving control efficiency.

[0029] In order to prevent excessive wastewater from accumulating in the ditch and overflowing when the incoming water volume is large, thus affecting the environment, and to prevent the sedimentation tank from overflowing due to excessive water volume, thus affecting the wastewater treatment efficiency and quality, this utility model proposes an automatic wastewater overflow adjustment device.

[0030] Please see Figure 1 In one embodiment of this utility model, the wastewater overflow automatic adjustment device includes:

[0031] Regulating tank 10, wherein the regulating tank 10 is provided with an inlet 40;

[0032] A clean water tank 60, wherein the clean water tank 60 is provided with a discharge port 70;

[0033] A sedimentation mechanism 50 is provided between the equalization tank 10 and the clear water tank 60, and is connected to the equalization tank 10 and the clear water tank 60.

[0034] The regulating mechanism includes a high level switch sensor 20, a low level switch sensor 30, and a pneumatic ball valve 80. The high level switch sensor 20 is located at the inlet 40, and the low level switch sensor 30 is located below the high level switch sensor 20 and has a height difference from it. The pneumatic ball valve 80 is located at the outlet 70 and is used to open or close the outlet 70.

[0035] like Figure 1 As shown, the equalization tank 10 is located before the sedimentation mechanism 50. The inlet 40 of the equalization tank 10 is used for the entry of wastewater. The acidity and alkalinity of the wastewater are adjusted in the equalization tank 10 to facilitate the subsequent treatment of the wastewater by the sedimentation mechanism 50.

[0036] like Figure 1As shown, a dosing tank is connected to the equalization tank 10, and the dosing tank contains a reagent for adjusting the pH.

[0037] It should be noted that the conditioning tank 10 is also equipped with a detector for detecting acidity and alkalinity.

[0038] Understandably, when a large amount of wastewater enters the equalization tank 10, the detector detects the pH of the liquid in the equalization tank 10. Based on the detected pH, the dosing tank adds chemicals to the equalization tank 10 to neutralize the glass wastewater. When the pH reaches the required level, the pre-treated wastewater in the equalization tank 10 is discharged into the sedimentation mechanism 50.

[0039] like Figure 1 As shown, the clear water tank 60 is located at the end of the wastewater treatment process and is used to hold the liquid treated by the sedimentation mechanism 50. The liquid is output according to the usage requirements to achieve the purpose of wastewater recycling.

[0040] It is understandable that the wastewater treated by the sedimentation mechanism 50 is collected by the clear water tank 60 for convenient centralized use. In order to facilitate the continuous wastewater treatment by the sedimentation mechanism 50, the clear water tank 60 also drains water while receiving the treated wastewater, so as to avoid the wastewater overflowing from the clear water tank and to avoid wasting the treated wastewater.

[0041] It should be noted that the bottom of the clean water tank 60 is provided with a drain pipe connected to the inlet 40. The drain pipe is used for transmission, so that the liquid at the bottom of the clean water tank 60 can flow back into the inlet, so as to facilitate the sewage treatment process again and avoid the poor treatment effect of the liquid affecting the quality of use.

[0042] like Figure 1 As shown, the high liquid level switch sensor 20 and the low liquid level switch sensor 30 are disposed on two adjacent planes, and the low liquid level switch sensor 30 is close to the inner bottom surface of the inlet 40, and there is a gap between the high liquid level switch sensor 20 and the inner top wall of the inlet 40.

[0043] Understandably, when wastewater enters the inlet 40, the high-level switch sensor 20 and the low-level switch sensor 30 detect the wastewater volume. When the high-level switch sensor 20 detects excessive wastewater volume, it sends an electrical signal to control the pneumatic ball valve 80 to open, thereby draining the clear water tank 60 and preventing overflow when excessive liquid enters the sedimentation mechanism 50. When the wastewater volume in the inlet 40 drops to between the high-level switch sensor 20 and the low-level switch sensor 30, the pneumatic ball valve 80 remains open to ensure the continued outflow of liquid from the clear water tank 60, ensuring stable and orderly sedimentation.

[0044] It should be noted that, in order to ensure the stability of the wastewater treated in the sedimentation mechanism 50, the wastewater volume in the sedimentation mechanism 50 needs to be kept within a constant range.

[0045] It is understandable that when the liquid in the inlet 40 is always between the high liquid level switch sensor 20 and the low liquid level switch sensor 30, the pneumatic ball valve 80 needs to be opened manually to avoid the amount of drainage affecting the quality of wastewater treatment in the sedimentation mechanism 50, and also to avoid the amount of drainage causing wastewater to overflow into the sedimentation mechanism 50.

[0046] The technical solution of this utility model involves installing a high-level switch sensor 20 and a low-level switch sensor 30 at the inlet of a wastewater treatment system, with the planes of the high-level switch sensor 20 and the low-level switch sensor 30 perpendicular to the liquid surface. This allows for the detection of water volume at the inlet. When excessive water enters the system, the pneumatic ball valve 80 is opened to quickly drain the clean water tank 60 until the water level at the inlet is lower than the plane of the low-level switch sensor 30. At this point, the pneumatic ball valve 80 automatically closes. This ensures that the start-up ball valve 80 automatically opens to drain water under large inflow conditions, guaranteeing automated wastewater treatment under such conditions, preventing uncontrolled overflow, and improving control efficiency.

[0047] In one embodiment, the distance between the top wall of the inlet 40 and the high liquid level switch sensor 20 is in the range of 200-300mm.

[0048] It should be noted that the inlet 40 is located on the regulating tank. In order to facilitate the liquid entering the inlet 40, the inlet 40 is connected to a groove, and the wastewater flows in the groove and enters the inlet 40.

[0049] It should be noted that, as the wastewater flows within the inlet 40, the water level fluctuates due to the flow. When the high-level switch sensor 20 is too close to the top wall of the inlet 40, it means that the wastewater level is close to the opening of the trench. This can easily cause the fluctuating water level to overflow, affecting the environment. Conversely, when the high-level switch sensor 20 is too far from the top wall of the inlet 40, the detected high level is too low, causing the water level to drop too quickly, which in turn results in the water intake not meeting the operating requirements of the system.

[0050] It is understood that the high liquid level switch sensor 20 is located at the inlet 40, and the distance between the high liquid level switch sensor 20 and the top wall of the inlet 40 is in an appropriate position, that is, the distance range is 200-300mm, so as to avoid the overflow of wastewater due to excessively high liquid level and to avoid the difficulty of equipment operation due to excessively low liquid level.

[0051] Preferably, the distance between the top wall of the inlet 40 and the high liquid level switch sensor 20 is 200mm.

[0052] In one embodiment, the height difference is 200 mm.

[0053] It should be noted that if the height difference is too small, although the required water volume is met and the equipment can operate smoothly, the water level drops too quickly between the high and low levels, resulting in a short control water level test piece. When the water volume fluctuates, the equipment is prone to repeated start-ups and shutdowns, which can reduce its service life. Conversely, if the height difference is too large, the equipment may operate for extended periods, further affecting its service life. Moreover, the water level drops too slowly between the high and low levels, leading to low water level control accuracy, which is detrimental to precise control of the equipment's operation.

[0054] It is understood that there is a height difference between the high liquid level switch sensor 20 and the low liquid level switch sensor 30, and the height difference is 200mm, which makes the liquid level drop rate uniform between the high and low liquid levels, ensuring the accuracy of water level control, thereby ensuring the intermittent and orderly operation of the equipment, avoiding repeated start-ups and shutdowns of the equipment, and avoiding the equipment's service life due to long-term operation.

[0055] In one embodiment, the wastewater overflow automatic regulating device further includes a control device, which is electrically connected to both the high liquid level switch sensor 20 and the low liquid level switch sensor 30, and is also electrically connected to the pneumatic ball valve 80.

[0056] It should be noted that when the high liquid level switch sensor 20 and the low liquid level switch sensor 30 sense a change in liquid level, they will generate relevant electrical signals. It is necessary to set up relevant devices to convert the electrical signals in order to achieve synchronous control of the pneumatic ball valve 80.

[0057] It is understood that the electrical signals generated by the high liquid level switch sensor 20 and the low liquid level switch sensor 30 when they sense changes in liquid level are received and converted by the control device. The converted electrical signals are received by the pneumatic ball valve 80, and the start and stop of the pneumatic ball valve 80 are controlled synchronously.

[0058] When the water level at the inlet 40 is high enough to trigger the high-level switch sensor 20 and the low-level switch sensor 30, both sensors generate electrical signals, which are received by the control device. The control device receives and converts the electrical signals and sends the converted signals to the pneumatic ball valve 80, thereby causing the clear water tank 60 to start draining water. When the water level at the inlet 40 is between the high and low levels, the low-level switch sensor 30 remains triggered while the high-level switch sensor 20 is not triggered. The pneumatic ball valve 80 remains open until the low-level switch sensor 30 is no longer triggered, at which point the pneumatic ball valve 80 closes.

[0059] Understandably, during the wastewater treatment process, when the water volume at the inlet 40 is too large, the pneumatic ball valve 80 is kept open by the wastewater overflow automatic adjustment device to ensure the stability of the water volume stored in the sedimentation mechanism 50, thereby ensuring the normal operation of the equipment. It also enables automatic overflow adjustment during large-flow water intake, improving the automation performance of the equipment.

[0060] In one embodiment, the control device includes a power supply unit, and the high liquid level switch sensor 20, the low liquid level switch sensor 30, and the pneumatic ball valve 80 are all connected to the power supply unit.

[0061] It is understood that the power supply unit is provided to provide energy for the operation of the high liquid level switch sensor 20, the low liquid level switch sensor 30, and the pneumatic ball valve 80.

[0062] In one embodiment, the control device further includes a switch assembly 90, which is electrically connected to the pneumatic ball valve 80, and both the high liquid level switch sensor 20 and the low liquid level switch sensor 30 are electrically connected to the switch assembly 90.

[0063] like Figure 2As shown, the high liquid level switch sensor 20 is connected to the power supply unit, and the low liquid level switch sensor 30 and the pneumatic ball valve 80 are both connected in parallel with the high liquid level switch sensor 20.

[0064] like Figure 2 As shown, the switch assembly 90 includes two first switches 91, a second switch 92, a third switch 93, a first relay, a second relay, and a third relay. The first relay is connected in series with the high liquid level switch sensor 20, the second relay is connected in series with the low liquid level switch sensor 30, and the third relay is connected in parallel with the pneumatic ball valve 80. The first switch, the second switch, and the third relay are connected in series. The pneumatic ball valve 80 is connected in series with one of the first switches 91, and the other first switch 91 is connected in parallel with the third switch 93.

[0065] It should be noted that the first relay is coupled to the third switch 93, the second relay is coupled to the second switch 92, and the third relay is coupled to the first switch.

[0066] It should be noted that the second and third switches are normally closed, while the two first switches 91 are normally open.

[0067] It should be noted that when neither the high liquid level switch sensor 20 nor the low liquid level switch sensor 30 is triggered, there is current in the circuits where the high liquid level switch sensor 20 and the low liquid level switch sensor 30 are located. At this time, the second switch and the third switch are in the open state, and there is no current in the circuit where the third relay is located, thereby causing the first switch 91 to be in the open state.

[0068] It is understandable that when the inlet 40 receives too much water, both the high / low level switch sensor 20 and the low level switch sensor 30 are triggered. At this time, there is no current in the circuits where the high / low level switch sensor 20 and the low level switch sensor 30 are located. The second switch and the third switch are closed. At this time, there is current in the circuit where the third relay is located, which in turn causes the two first switches to be closed. This causes current to be present in the circuit where the pneumatic ball valve 80 is located, thereby controlling the pneumatic ball valve 80 to be open. In this way, automatic control is achieved when there is a large amount of incoming water, preventing wastewater overflow.

[0069] It is understandable that when the water level at the inlet 40 drops from the plane where the high-level switch sensor 20 is located to between the plane where the high-level switch sensor 20 is located and the low-level switch sensor 30, there is current in the circuit where the high-level switch sensor 20 is located while there is no current in the circuit where the low-level switch sensor 30 is located. This causes the second switch to be closed and the third switch to be open. At this time, since the first switch connected in parallel with the third switch is still closed, there is still current flowing through the third relay, which in turn causes both switches to remain closed. At this time, the pneumatic ball valve 80 remains open, which facilitates the control of the clear water tank 60 to continue draining water and ensures the stable operation of the sedimentation mechanism when the incoming water volume is sufficient.

[0070] It is understandable that when the wastewater level is below the plane where the low level switch sensor 30 is located, both first switches 91, second switches 92, third switches 93, first relay, second relay and third relay are reset, thereby causing the pneumatic ball valve 80 to close, thus ensuring the liquid level in the sedimentation mechanism 50.

[0071] In one embodiment, the sedimentation mechanism 50 further includes a plurality of sedimentation tanks 52, which are spaced apart. Each of the sedimentation tanks 52 has a liquid outlet at its top, and each of the liquid outlets is connected to the clear water tank 60. Furthermore, each of the sedimentation tanks 52 is connected to the regulating tank 10.

[0072] like Figure 1 As shown, in order to treat a large amount of wastewater, multiple sedimentation tanks 52 are provided, and each sedimentation tank 52 is connected to the clear water tank 60.

[0073] It is understood that each of the sedimentation tanks 52 is connected to the clear water tank 60 so that the treated liquid in each sedimentation tank 52 can directly enter the clear water tank 60, thus avoiding cross-flow of liquid between multiple sedimentation tanks 52 and affecting the wastewater treatment quality.

[0074] like Figure 1 As shown, the liquid outlet of the sedimentation tank 52 is located at the top of the sedimentation tank 52, that is, the liquid discharged from the sedimentation tank 52 flows out from the top of the sedimentation tank 52.

[0075] It is understandable that when the sedimentation tank 52 is treating wastewater, particulate matter and other substances will settle on the lower side of the sedimentation tank 52, while the upper layer is the treated liquid, so as to avoid the cleaned liquid becoming cloudy again and affecting the treatment quality.

[0076] In one embodiment, the sedimentation mechanism further includes a sludge tank 53, and the bottom of each of the plurality of sedimentation tanks 52 is provided with a sludge outlet, and the plurality of sludge outlets are connected to the sludge tank 53.

[0077] It should be noted that the treated wastewater is placed in the sedimentation tank 52, which causes the wastewater to be stratified within the sedimentation tank 52, that is, the clear liquid is located on the upper side of the sedimentation tank 52, while the fixed sediment is located on the lower side of the sedimentation tank 52.

[0078] It is understood that the sludge outlet is provided at the bottom of the sedimentation tank 52. When there is too much sediment in the sedimentation tank 52, the sludge outlet is opened, so that the sediment automatically enters the sludge tank 53 along the pipe, thereby cleaning the sediment in the sedimentation tank 52 and facilitating the normal operation of subsequent wastewater treatment.

[0079] It should be noted that, in order to achieve the separation of liquid in the sludge in the sludge tank, the sludge tank 53 is connected to a plate and frame filter press, and the solid-liquid separation in the sludge tank 53 is achieved by the filtration of the plate and frame filter press.

[0080] It is understandable that in order to ensure that each sedimentation tank 52 can operate normally and achieve normal wastewater treatment, the wastewater level in each sedimentation tank 52 needs to be maintained within a certain range. Therefore, when the water flow into the sedimentation tank 52 is too large, the second drain of the clear water tank 60 needs to be implemented in a timely manner to balance the liquid level in the sedimentation tank 52 and ensure the normal operation of wastewater treatment.

[0081] In one embodiment, the sedimentation mechanism further includes a reaction tank 51, and a plurality of sedimentation tanks 52 are connected to the reaction tank 51, and the reaction tank 51 is connected to the regulating tank 10.

[0082] It should be noted that, in order to facilitate solid-liquid separation of wastewater in the sedimentation tank 52, a reaction tank 51 is provided on one side of the sedimentation tank 52. By adding reagents into the reaction tank 51, the wastewater undergoes a preliminary reaction in the reaction tank 51, so that the wastewater can be quickly separated after being transferred to the sedimentation tank 52.

[0083] In one embodiment, a plurality of transmission pipes are connected in parallel between the reaction tank 51 and the regulating tank 10, and regulating valves are provided in the transmission pipes.

[0084] To ensure flow regulation from the equalization tank 10 to the reaction tank 51, multiple transmission pipes are provided between the reaction tank 51 and the equalization tank 10, and regulating valves are installed in the transmission pipes. The required number of regulating valves are controlled according to the incoming water volume, so that multiple transmission pipes can transmit water to the reaction tank 51 simultaneously, ensuring the normal operation of wastewater treatment and preventing wastewater overflow.

[0085] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
