Description

Technical Field

[0001] The present application relates to the field of water supply dosing control, and in particular to an intelligent dosing control system and method for water supply. Background Art

[0002] Domestic water in cities usually needs to go through multiple stages of sedimentation and purification to reduce impurities in the water.

[0003] In the prior art, a certain amount of reagent is usually weighed and directly put into the purification tank, and the injection position is concentrated in a smaller area. Under the action of the flow of the water body, the diffusion of the reagent is achieved, so that the water in the purification tank is mixed with the reagent everywhere, and the reagent reacts chemically with the impurities in the water to produce precipitation. However, in order to improve the efficiency of water services, the purification tank is usually extended, and the water to be purified is continuously input at the inlet of the purification tank, and the purified water is continuously output at the outlet of the purification tank. Therefore, the reagent content in the water in the purification tank will continue to decrease, and the reagent content in the water near the inlet will be lower than the reagent content in the water near the outlet, resulting in uneven reagent concentration at different positions of the water body. Moreover, due to the large area of ​​the purification tank, it is difficult to achieve uniform mixing of the reagent and the water body by relying on the water flow, which affects the purification effect.

When the hydraulic drum 100 rotates relative to the fixed shaft 102, each second movable through hole 178 can be periodically aligned with the fixed through hole 134 in the vertical direction in turn; a drain port 140 is provided on the side wall of the water storage chamber 126, and the drain port 140 is located on the rear baffle 110 and penetrates the rear baffle 110; the rotor 116 and the stator 118 are located in the interval space 136, and the stator 118 is sleeved on the fixed shaft 102 and fixedly connected to the fixed shaft 102. The rotor 116 is sleeved on the stator 118, the outer side of the rotor 116 is fixedly connected to the inner side of the hydraulic drum 100, and the outer side of the stator 118 is gap-matched with the inner side of the rotor 116; the coil winding in the stator 118 is connected to the current sensor 124, and the current sensor 124 is used to detect the induced current in the coil winding in the stator 118; the air compressor 114, the current sensor 124, and the air pressure sensor 122 are respectively connected to the controller 120, the air compressor 114 is suitable for pressurizing the upper space in the medicine box 112, and the air pressure sensor 122 is used to detect the air pressure in the upper space in the medicine box 112. The rotor 116 is relative to the stator 1 After 18 rotates, an induced current is generated in the coil winding in the stator 118, and the controller 120 is suitable for controlling the operation of the air compressor 114 according to the induced current and the air pressure in the upper space of the medicine box 112; the bottom surface of the left baffle 104, the bottom surface of the right baffle 106, the bottom surface of the front baffle 108, and the bottom surface of the rear baffle 110 are located on the same horizontal plane, and the left baffle 104, the right baffle 106, the front baffle 108 and the rear baffle 110 are suitable for being installed in the dam mouth, and the left baffle 104 and the right baffle 106 are suitable for being fixedly connected to the left side and the right side of the dam mouth respectively, and the bottom surfaces of the front baffle 108 and the rear baffle 110 are suitable for being fixedly connected to the bottom surface of the dam mouth respectively.

[0022] The control system (intelligent dosing control system for water affairs) is installed in the dam mouth of the purification pool. When the water in the purification pool flows out from the dam mouth to the next purification pool, the water first flows into the water storage chamber 126 from the water outlet 128. In this process, the water drives the hydraulic drum 100 to rotate through the blades 130. During the rotation of the hydraulic drum 100, the first movable through hole 132 and the fixed through hole 134 are periodically aligned, and the air compressor 114 pressurizes the inside of the medicine box 112, so that the medicine solution in the medicine box 112 is input into the fixed shaft 102, and then periodically sprayed from the fixed through hole 134 and the first movable through hole 132 into the water storage chamber 126 in turn. The greater the water flow rate, the faster the rotation speed of the hydraulic drum 100. The larger the diameter of the first movable through hole 132 and the fixed through hole 134, the shorter the period of alignment between the first movable through hole 132 and the fixed through hole 134, the higher the frequency of the agent spraying into the water storage chamber 126, the larger the amount of the agent added to the water storage chamber 126, and the agent is automatically added to the water according to the water flow rate. Each portion of water first flows into the water storage chamber 126 and mixes with the agent sprayed into the water storage chamber 126. The mixed water is then discharged from the drain port 140 into the next purification tank, thereby improving the uniformity of the mixing of the agent and water in the next purification tank. During the rotation of the hydraulic drum 100, the coil winding in the stator 118 generates an induced current, the current sensor 124 detects the induced current and transmits the detected induced current to the controller 120, and the water flow in the dam mouth is The larger the amount, the greater the speed of the hydraulic drum 100, the greater the induced current generated, and the controller 120 controls the working state of the air compressor 114 according to the size of the induced current, and also controls the operation of the air compressor 114 according to the air pressure in the medicine box 112. Preferably, when the air pressure in the compression space is less than the minimum preset air pressure, the controller 120 controls the air compressor 114 to start; when the induced current is greater than or less than the minimum preset current, the controller 120 controls the air compressor 114 to operate in a high-speed mode; when the induced current is greater than or equal to the minimum preset current and less than or equal to the maximum preset current, the controller 120 controls the air compressor 114 to operate in a mid-speed mode; when the induced current is greater than the maximum preset current, the controller 120 controls the air compressor 114 to operate in a mid-speed mode. The controller 120 controls the air compressor 114 to operate in a low gear mode; when the air pressure in the compression space is greater than or equal to the maximum preset air pressure, the controller 120 controls the air compressor 114 to stop operating; in this embodiment, the minimum preset air pressure is 0.5 MPa, the minimum preset current is 0.2 ampere, the maximum preset current is 1.2 ampere, and the maximum preset air pressure is 2.7 MPa. It should be understood that the preset values ​​in this embodiment (including the minimum preset air pressure, the minimum preset current, the maximum preset current, and the maximum preset air pressure) need to be set in combination with specific working conditions. The larger the water flow in the dam mouth, the larger the corresponding preset value. The minimum preset current may not change with the water flow at the dam mouth, and may also be set to 0.5 MPa, because when the water flow is too large and fills the water storage chamber 126 and overflows from the rear baffle 110, the thrust of the water flow on the blade 130 in a circumferential direction will decrease, and the generated induced current will no longer change with the size of the water flow at the dam mouth. The induced current generated at this time plus 0.2 amperes is used as the minimum preset current; it can be seen that the above-mentioned implementation of this embodiment can automatically adjust the dosing frequency according to the size of the water flow at the dam mouth, which is helpful to improve the mixing uniformity of the agent and the purified water body, and automatically adjust the dosing frequency of each dosing according to the size of the water flow at the dam mouth. The dosage of the medicine is to automatically adjust the concentration of the medicine in the water so that the concentration of the medicine in the water is within the expected range (based on the effect of purifying water). If the water volume in a purification pool is 1,000 tons, a total of 1 ton of medicine needs to be added, the water flow rate at the dam mouth is 100 kilograms per minute, and the frequency of aligning the second active through hole 178 with the fixed through hole 134 is 50 times per minute, then the amount of medicine sprayed each time needs to reach a concentration of one thousandth in 2 kilograms of water, so the amount of medicine sprayed from the fixed through hole 134 into the water storage chamber 126 each time should be 2 grams. .

[0023] In some exemplary embodiments, the drain port 140 is higher than the bottom of the water storage chamber 126 (eg, Figure 7 as shown).

[0024] The water flowing into the water storage chamber 126 from the drain port 128 will not be immediately discharged from the drain port 140, but will be mixed with the water and the medicine in the water storage chamber 126, and then discharged from the drain port 140 after mixing, which further improves the uniformity of mixing the medicine and water.

[0025] In some exemplary embodiments, the tailgate 110 is provided with an overflow port 170, which is connected to the water storage space and is higher than the drain port 140 (eg, Figure 7 as shown).

[0026] The overflow port 170 is at the same height as the lowest position of the rotation space of the blade 130. When the water volume at the dam mouth increases to the point where the water in the water storage chamber 126 cannot be discharged in time by relying on the drain port 140, the water level in the water storage chamber 126 will gradually rise. When the water submerges the blade 130, it will hinder the rotation of the blade 130, reducing the dosing and mixing efficiency. At this time, the water that is higher than the lowest position of the rotation space of the blade 130 will rush out of the overflow port 170. The drain port 140 and the overflow port 170 drain water at the same time, which can avoid or slow down the further continuous rise of the water level.

[0027] In some exemplary embodiments, a first electric gate 172 and a second electric gate 174 are installed on the tailgate 110, the first electric gate 172 is used to open or close the drain outlet 140, and the second electric gate 174 is used to open or close the overflow outlet 170, the first electric gate 172 and the second electric gate 174 are respectively connected to the controller 120, and the controller 120 is suitable for controlling the operation of the first electric gate 172 and the second electric gate 174 according to the induced current and the air pressure in the upper space of the medicine box 112.

[0028] When the air pressure in the compression space is greater than or equal to the maximum preset air pressure and the induced current is greater than or less than the minimum preset current, the controller 120 controls the second electric gate 174 to open to achieve rapid drainage, otherwise the second electric gate 174 is closed to prevent water from being discharged from the overflow port 170 after being stirred or splashed.

[0029] In some exemplary embodiments, a sewage outlet 168 is provided on the tailgate 110, and the sewage outlet 168 is lower than the water outlet 140. The sewage outlet 168 is connected to the bottom of the water storage chamber 126. A third electric gate 176 is installed on the tailgate 110. The third electric gate 176 is used to open or close the sewage outlet 168. The third electric gate 176 is connected to the controller 120, and the controller 120 is suitable for periodically controlling the third electric gate 176 to open or close the sewage outlet 168.

[0030] The sewage outlet 168 is mainly used to discharge floating objects or sediments entering the water storage chamber 126 from the water outlet 128, so as to avoid blockage of the drainage outlet 140 and the overflow outlet 170 due to long-term operation, and to avoid the floating objects and sediments occupying the bottom space of the water storage chamber 126. The cycle length of the periodic opening and closing of the third electric gate 176 is determined according to the water flow rate at the dam mouth and the cleanliness of the water. The greater the water flow rate at the dam mouth and the lower the water cleanliness, the shorter the cycle.

[0031] Combination Figure 4 and Figure 7 As shown, in some exemplary embodiments, the top surface of the rear baffle 110 is higher than the top surfaces of the drain port 128 and the front baffle 108 , and the top surfaces of the left baffle 104 and the right baffle 106 are higher than the top surface of the rear baffle 110 .

[0032] The top surface of the rear baffle 110 is higher than the top surfaces of the drain port 128 and the front baffle 108. When the water flow at the dam mouth increases to fill the water storage chamber 126 and is lower than the top surface of the rear baffle 110, it can prevent water from flowing over the rear baffle 110 and being discharged directly into the next purification tank without mixing with the reagent; the top surfaces of the left baffle 104 and the right baffle 106 are higher than the top surface of the rear baffle 110, which prevents water from overflowing from the top of the left baffle 104 and the right baffle 106 when the water flow is too large.

[0033] In some exemplary embodiments, a battery 142 is further included. The controller 120 is connected to the battery 142 . The battery 142 is used to store the electrical energy generated by the induced current and to supply power to the controller 120 , the air pressure sensor 122 , and the air compressor 114 .

[0034] Since the water input and discharge volumes of the purification pool are usually not precisely controlled, the water flow rate in the dam mouth is not always constant. When the water flow rate is relatively small, the electric energy generated by the induced current is relatively small, and it is difficult to maintain the operation of the air compressor 114, the air pressure sensor 122, and the controller 120. At this time, the battery 142 is used for power supply. When the water volume is large, part of the electric energy generated by the induced current is stored in the battery 142 to reserve power when the water volume is small. This is convenient for graded purification of dams in suburban or mountainous areas, and overcomes the problem of difficulty in laying electrical wires.
