Description

Technical Field

[0001] The invention relates to the technical field of sterilization equipment, and in particular to a flow-through sterilizer with a built-in water flow switch. Background Art

[0002] The over-flow sterilizer is mainly composed of a shell, a UV lamp, a UV sleeve, a rectifier, a timer, a sight glass, a sewage outlet, a water inlet and outlet, an indicator light, a switch and a power cord. Its sterilization principle is to destroy the DNA structure of microorganisms in the water through the energy of ultraviolet photons, so that they cannot replicate and reproduce, thereby achieving the sterilization effect. The UV sterilizer has a killing effect on almost all bacteria and viruses and has a broad spectrum, so it can be widely used in drinking water, municipal sewage, swimming pool water treatment and other fields. Due to its high efficiency and environmental protection, it has gradually become one of the mainstream disinfection technologies.

[0003] The over-flow sterilizer can achieve a high sterilization rate in a short time, usually 99-99.9% in one to two seconds, and does not use any chemical agents, will not cause secondary pollution, will not produce toxic side effects, and has no negative impact on water quality. Compared with other disinfection methods, ultraviolet sterilizers require smaller space, are simple to operate, and are easy to maintain;

[0004] However, the over-flow UV sterilizer needs to be cleaned and disinfected regularly to prevent the accumulation of dust and dirt that affect its sterilization effect. These maintenance tasks also require certain professional skills and increase maintenance. Turbidity and suspended matter in the water have a greater impact on UV sterilization, reducing the disinfection effect. In addition, the UV lamp sleeve is prone to scaling, which affects the transmission of UV light and the sterilization effect.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to automatically clean the ultraviolet sterilization tube through a cleaning mechanism, calculate the water source assessment coefficient according to the frequency of cleaning signal generation and the corresponding information source, so as to adjust the water inlet at the water inlet, and avoid overloading the flow-through sterilizer and causing poor sterilization effect.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a flow-through sterilizer with a built-in water flow switch, comprising a shell, a water inlet, a drain and an intelligent control system, the water inlet and the drain are respectively arranged on the outer surface of the shell and extend to the interior of the shell, a support frame is fixedly provided on the outer surface of the shell, and it is characterized in that a filter screen is detachably connected to the inner wall of the drain screen, a water flow switch is fixedly provided on the inner wall of the drain screen above the filter screen, a plurality of ultraviolet lamp tubes are evenly distributed on the inner wall of the shell, a cleaning mechanism is movably provided on the outer surfaces of the plurality of ultraviolet lamp tubes, a driving mechanism is fixedly provided on the inner wall of the shell, and the driving mechanism and the cleaning mechanism are connected to each other.

[0008] Furthermore, the cleaning mechanism comprises a connecting spring and a cleaning component. The two cleaning components are movably sleeved on the outer surface of the ultraviolet lamp tube respectively, and the connecting spring is connected between the cleaning component and the inner wall of the shell.

[0009] Furthermore, the cleaning component includes a movable snap ring and a cleaning wipe block, the movable snap ring is movably sleeved on the outside of the ultraviolet lamp tube, an electric connection ring is fixedly provided on the inner wall of the movable snap ring, and a plurality of piezoelectric ceramic shafts are evenly distributed on the inner wall of the electric connection ring, the cleaning wipe block is fixedly provided on the outer surface of the piezoelectric ceramic shaft, the outer surface of the cleaning wipe block is in close contact with the outer surface of the ultraviolet lamp tube, the outer surface of the movable snap ring is fixedly provided with a connecting support shaft, and the connecting spring is connected between the connecting support shaft and the inner wall of the shell.

[0010] Furthermore, the driving mechanism includes an electromagnet and a magnet ring, a fixed support shaft is fixedly provided at the center position of the shell, the electromagnet is sleeved on the outer surface of the fixed support shaft, the magnet ring is movably sleeved on the outer surface of the fixed support shaft, and the ends of the connecting support shaft are both connected to the outer surface of the magnet ring.

[0011] Furthermore, the outer surfaces of the electromagnet, the magnet ring and the power connection ring are all coated with a sealing and waterproof coating.

[0012] Furthermore, the intelligent control system includes an ultraviolet monitoring unit, a water flow sensing unit, a total control unit and a sterilization analysis unit;

[0013] The ultraviolet monitoring unit is used to obtain real-time ultraviolet intensity data in the shell through an ultraviolet monitor detector arranged in the shell, and obtain stable ultraviolet intensity data after preprocessing the real-time ultraviolet intensity data, and judge whether the ultraviolet intensity data meets the sterilization standard according to a preset sterilization judgment value, so as to generate a cleaning signal and send it to the main control unit;

[0014] The water flow sensing unit is used to obtain the on / off signal of the water flow switch to generate a cleaning signal and send it to the main control unit;

[0015] The sterilization analysis unit is used to obtain the frequency and information source of the cleaning signal within a preset monitoring period, calculate the water source assessment coefficient according to the frequency of the cleaning signal and the corresponding information source, and generate a flow control signal to the general control unit according to the water source assessment coefficient;

[0016] The general control unit includes a cleaning control module and a water flow control module. The cleaning control module is used to obtain a cleaning signal to control the driving mechanism to drive the cleaning mechanism to automatically clean the ultraviolet sterilization tube to ensure the sterilization effect;

[0017] The water flow control module is used to obtain a flow control signal and display it through a remote monitoring system to adjust the water inlet at the water inlet.

[0018] Furthermore, the specific process of the ultraviolet monitoring unit generating a cleaning signal is as follows:

[0019] S101, obtaining real-time ultraviolet intensity data in the shell through an ultraviolet monitor arranged on the inner wall of the shell, obtaining multiple real-time ultraviolet intensity data in a monitoring period, cleaning the multiple real-time ultraviolet intensity data respectively, and arranging them in time series according to the monitoring period to obtain stable ultraviolet intensity data UVi;

[0020] S102, obtaining a preset ultraviolet sterilization range (UVmin, UVmax), and calculating the ultraviolet fluctuation coefficient Eu according to the following normalized formula: Where i = 1, 2, 3, ..., n, n is the number of ultraviolet intensity data, and the ultraviolet fluctuation coefficient is used to reflect the sterilization effect of the ultraviolet lamp. The larger the ultraviolet fluctuation coefficient, the worse the sterilization effect, and the smaller the ultraviolet fluctuation coefficient, the more in line with the standard the sterilization effect;

[0021] S103, obtaining a preset sterilization judgment value. If the ultraviolet fluctuation coefficient is greater than or equal to the sterilization judgment value, it means that there is scaling on the outer surface of the ultraviolet lamp tube, resulting in a decrease in ultraviolet intensity. At this time, a cleaning signal is generated and sent to the main control unit;

[0022] If the UV fluctuation coefficient is less than the sterilization judgment value, it means that there is no scaling on the outer surface of the UV lamp tube, and no signal is generated at this time.

[0023] Furthermore, the specific process of the water flow sensing unit generating a cleaning signal is as follows:

[0024] Get the preset flow threshold of the water flow switch. When the water flows through the valve in the water flow switch, the pressure of the water flow acts on the sensor. The sensor converts the pressure into a control signal through an electrical signal. When the water flow is lower than the preset flow threshold, a closing signal is generated. After the valve is closed, a cleaning signal is automatically generated.

[0025] Furthermore, the specific process of generating the flow control signal is as follows:

[0026] 204. Obtain the frequency Fh and information source of the cleaning signal H, wherein the information source includes an ultraviolet interference source and a water flow sensing source, wherein the ultraviolet interference source is marked with Ha, and the water flow sensing source is marked with Hb;

[0027] 205. Calculate the water source assessment coefficient Wu according to the following formula: Where e1 and e2 are preset proportional coefficients, n is the number of ultraviolet interference sources, m is the number of water flow sensing sources, and the water source assessment coefficient is used to reflect the impurity content in the water source entering the over-flow sterilizer. The higher the water source assessment coefficient, the more impurities there are in the water source, and the lower the water source assessment coefficient, the less impurities there are in the water source.

[0028] 206. Obtain a preset evaluation threshold value. If the water source evaluation coefficient is greater than or less than the evaluation threshold value, no signal is generated.

[0029] If the water source assessment coefficient is greater than or less than the assessment threshold, a flow control signal is generated, and at the same time, the flow adjustment data Q is calculated according to the preset flow control coefficient k: Q=k*Wu.

[0030] The flow control signal is analyzed to obtain flow adjustment data.

[0031] Furthermore, the remote monitoring system is a PC-side monitoring device arranged outside the sterilization environment. After acquiring the flow control signal, the flow control signal is analyzed to obtain the flow adjustment data.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. The built-in water flow switch over-current sterilizer automatically closes the water outlet through the water flow switch and generates a cleaning signal. The intelligent control system controls the electromagnet to intermittently turn on and off the power for many times. The two ends of the electromagnet have opposite magnetism to the corresponding magnet ring, so that it has magnetism and generates magnetic attraction between the magnet ring when it is energized, driving the two magnet rings to approach each other along the fixed support shaft, and then driving the movable clamp ring to move along the outside of each ultraviolet lamp tube. The outside of the ultraviolet lamp tube is wiped by the cleaning wiper, which ensures the sterilization effect of the ultraviolet lamp tube and avoids inadequate sterilization.

[0034] 2. The built-in water flow switch over-current sterilizer connects the power ring to the circuit, so that the piezoelectric ceramic shaft produces a reverse piezoelectric effect after being energized, driving the cleaning wipe to vibrate on the outside of the ultraviolet lamp, thereby enhancing the cleaning effect, erasing the scale on the surface of the ultraviolet lamp, and ensuring the sterilization effect of the ultraviolet lamp. Since the cleaning component moves repeatedly along the inside of the shell, the water flow in the shell is disturbed, driving the impurities at the filter to vibrate, which also has a cleaning effect on the filter.

[0035] 3. The built-in water flow switch over-flow sterilizer obtains real-time ultraviolet intensity data in the shell through the ultraviolet monitor arranged on the inner wall of the shell, and judges whether the ultraviolet intensity data reaches the sterilization standard according to the preset sterilization judgment value to generate a cleaning signal, and at the same time obtains the on-off signal of the water flow switch to generate a cleaning signal, so as to control the driving mechanism to drive the cleaning mechanism to automatically clean the ultraviolet sterilization tube, and calculates the water source assessment coefficient according to the frequency of the cleaning signal generation and the corresponding information source to adjust the water inlet at the water inlet to avoid overload of the over-flow sterilizer and cause poor sterilization effect.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] like Figure 1-3 As shown, a flow-through sterilizer with a built-in water flow switch 6 comprises a shell 1, a water inlet 2, a drain outlet 3 and an intelligent control system. The water inlet 2 and the drain outlet 3 are respectively arranged on the outer surface of the shell 1 and extend to the interior of the shell 1. A support frame 4 is fixedly provided on the outer surface of the shell 1. A filter screen 5 is detachably connected to the inner wall of the drain outlet 3. A water flow switch 6 is fixedly provided on the inner wall of the drain outlet 3 above the filter screen 5. A plurality of ultraviolet lamp tubes 7 are evenly distributed on the inner wall of the shell 1. Cleaning mechanisms are movably sleeved on the outer surfaces of the plurality of ultraviolet lamp tubes 7. A driving mechanism is fixedly provided on the inner wall of the shell 1. The driving mechanism and the cleaning mechanism are connected to each other.

[0044] The cleaning mechanism comprises a connecting spring 8 and a cleaning component. The two cleaning components are movably sleeved on the outer surface of the ultraviolet lamp tube 7 respectively. The connecting spring 8 is connected between the cleaning component and the inner wall of the housing 1 .

[0045] The cleaning component includes a movable snap ring 9 and a cleaning wipe 12. The movable snap ring 9 is movably sleeved on the outer side of the ultraviolet lamp tube 7. An electric connection ring 10 is fixedly arranged on the inner wall of the movable snap ring 9. A plurality of piezoelectric ceramic shafts 11 are evenly distributed on the inner wall of the electric connection ring 10. The cleaning wipe 12 is fixedly arranged on the outer surface of the piezoelectric ceramic shaft 11. The outer surface of the cleaning wipe 12 is in close contact with the outer surface of the ultraviolet lamp tube 7. A connecting support shaft 13 is fixedly arranged on the outer surface of the movable snap ring 9. A connecting spring 8 is connected between the connecting support shaft 13 and the inner wall of the shell 1.

[0046] The driving mechanism includes an electromagnet 15 and a magnet ring 16. A fixed support shaft 14 is fixed at the center position of the shell 1. The electromagnet 15 is sleeved on the outer surface of the fixed support shaft 14. The magnet ring 16 is movably sleeved on the outer surface of the fixed support shaft 14. The ends of the connecting support shaft 13 are all connected to the outer surface of the magnet ring 16.

[0047] The outer surfaces of the electromagnet 15, the magnet ring 16 and the power connection ring 10 are all coated with a sealing and waterproof coating.

[0048] Working principle: Plug the over-current sterilizer into the power supply and turn on the switch. The power supply will provide the working voltage, so that the electronic control part starts to work. After the start circuit receives the signal, it will supply power to the ultraviolet lamp 7, and at the same time turn on the protection circuit, and introduce the water source to be sterilized through the water inlet 2. The ultraviolet lamp 7 starts to emit ultraviolet rays, which are irradiated to the sterilization target through the lamp. The ultraviolet rays can destroy the nucleic acid and protein of microorganisms, and by changing their structure and function, make them lose their life activity ability, thereby achieving the purpose of killing microorganisms;

[0049] The sterilized water flows out from the drain port 3 and is filtered through the filter 5. When there are too many impurities in the water source, the filter 5 is blocked, which reduces the amount of water flowing through the water flow switch 6. When the water volume is lower than the preset water volume value, the water flow switch 6 is automatically closed and generates a cleaning signal. The electromagnet 15 is controlled to be intermittently turned on and off for many times through the intelligent control system. The two ends of the electromagnet 15 have opposite magnetic properties to the corresponding magnet ring 16. When it is energized, it has magnetism and generates magnetic attraction with the magnet ring 16, driving the two magnet rings 16 to approach each other along the fixed support shaft 14, thereby driving the movable clamp ring 9 to move along the outside of each ultraviolet lamp tube 7, and the outside of the ultraviolet lamp tube 7 is wiped by the cleaning wiper 12.

[0050] At the same time, the power connection ring 10 is connected to the circuit, so that the piezoelectric ceramic shaft 11 generates a reverse piezoelectric effect after being energized, driving the cleaning wiper 12 to vibrate on the outside of the ultraviolet lamp tube 7, thereby enhancing the cleaning effect, erasing the scale on the surface of the ultraviolet lamp tube 7, and ensuring the sterilization effect of the ultraviolet lamp tube 7. Since the cleaning component repeatedly moves along the inside of the shell 1, the water flow in the shell 1 is disturbed, driving the impurities at the filter screen 5 to vibrate, which also has a cleaning effect on the filter screen 5.

[0051] Embodiment 2:

[0052] like Figure 4 As shown, a flow-through sterilizer with a built-in water flow switch 6 includes a housing 1, a water inlet 2, a drain 3 and an intelligent control system, wherein the intelligent control system includes an ultraviolet monitoring unit, a water flow sensing unit, a total control unit and a sterilization analysis unit;

[0053] The ultraviolet monitoring unit is used to obtain real-time ultraviolet intensity data in the shell 1 through an ultraviolet monitor arranged on the inner wall of the shell 1, and obtain stable ultraviolet intensity data after preprocessing the real-time ultraviolet intensity data, and judge whether the ultraviolet intensity data reaches the sterilization standard according to a preset sterilization judgment value, so as to generate a cleaning signal and send it to the main control unit;

[0054] The water flow sensing unit is used to obtain the on / off power signal of the water flow switch 6 to generate a cleaning signal and send it to the main control unit;

[0055] The sterilization analysis unit is used to obtain the frequency of the cleaning signal and the information source within a preset monitoring period, calculate the water source assessment coefficient according to the frequency of the cleaning signal and the corresponding information source, and generate a flow control signal to the general control unit according to the water source assessment coefficient;

[0056] The main control unit includes a cleaning control module and a water flow control module. The cleaning control module is used to obtain a cleaning signal to control the driving mechanism to drive the cleaning mechanism to automatically clean the ultraviolet sterilization tube to ensure the sterilization effect;

[0057] The water flow control module is used to obtain the flow control signal and display it through the remote monitoring system to adjust the water inlet at the water inlet 2.

[0058] The specific process of the UV monitoring unit generating a cleaning signal is as follows:

[0059] S101, obtaining real-time ultraviolet intensity data in the housing 1 through an ultraviolet monitor arranged on the inner wall of the housing 1, obtaining multiple real-time ultraviolet intensity data within a monitoring period, cleaning the multiple real-time ultraviolet intensity data respectively, and arranging them in time series according to the monitoring period to obtain stable ultraviolet intensity data UVi;

[0060] S102, obtaining a preset ultraviolet sterilization range (UVmin, UVmax), and calculating the ultraviolet fluctuation coefficient Eu according to the following normalized formula: Where i=1, 2, 3, ..., n, n is the number of ultraviolet intensity data, and the ultraviolet fluctuation coefficient is used to reflect the sterilization effect of the ultraviolet lamp 7. The larger the ultraviolet fluctuation coefficient, the worse the sterilization effect, and the smaller the ultraviolet fluctuation coefficient, the more in line with the standard the sterilization effect;

[0061] S103, obtaining a preset sterilization judgment value. If the ultraviolet fluctuation coefficient is greater than or equal to the sterilization judgment value, it means that there is scaling on the outer surface of the ultraviolet lamp tube 7, which causes the ultraviolet intensity to decrease. At this time, a cleaning signal is generated and sent to the main control unit;

[0062] If the ultraviolet fluctuation coefficient is less than the sterilization judgment value, it means that there is no scaling on the outer surface of the ultraviolet lamp tube 7, and no signal is generated at this time.

[0063] The specific process of the water flow sensing unit generating a cleaning signal is as follows:

[0064] Obtain the preset flow threshold of the water flow switch 6. When the water flows through the valve in the water flow switch 6, the pressure of the water flow acts on the sensor, and the sensor converts the pressure into a control signal through an electrical signal. When the water flow is lower than the preset flow threshold, a closing signal is generated, and a cleaning signal is automatically generated after the valve is closed.

[0065] The specific process of generating flow control signals is as follows:

[0066] 207. Obtain the frequency Fh and information source of the cleaning signal H, where the information source includes an ultraviolet interference source and a water flow induction source, wherein the ultraviolet interference source is marked with Ha, and the water flow induction source is marked with Hb;

[0067] 208. Calculate the water source assessment coefficient Wu according to the following formula: Where e1 and e2 are preset proportional coefficients, n is the number of ultraviolet interference sources, m is the number of water flow sensing sources, and the water source assessment coefficient is used to reflect the impurity content in the water source entering the over-flow sterilizer. The higher the water source assessment coefficient, the more impurities there are in the water source, and the lower the water source assessment coefficient, the less impurities there are in the water source.

[0068] 209. Obtain a preset assessment threshold value. If the water source assessment coefficient is greater than or less than the assessment threshold value, no signal is generated;

[0069] If the water source assessment coefficient is greater than or less than the assessment threshold, a flow control signal is generated, and at the same time, the flow adjustment data Q is calculated according to the preset flow control coefficient k: Q=k*Wu.

[0070] The flow control signal is analyzed to obtain flow adjustment data.

[0071] The remote monitoring system is a PC-side monitoring device installed outside the sterilization environment. After acquiring the flow control signal, the flow control signal is analyzed to obtain the flow adjustment data.

[0072] The present invention obtains real-time ultraviolet intensity data in the shell 1 through an ultraviolet detector arranged on the inner wall of the shell 1, and judges whether the ultraviolet intensity data reaches the sterilization standard according to a preset sterilization judgment value to generate a cleaning signal, and at the same time obtains the on-off signal of the water flow switch 6 to generate a cleaning signal, so as to control the driving mechanism to drive the cleaning mechanism to automatically clean the ultraviolet sterilization tube, and calculates the water source assessment coefficient according to the frequency of the cleaning signal generation and the corresponding information source to adjust the water inlet at the water inlet 2 to avoid overloading the overflow sterilizer and causing poor sterilization effect.

[0073] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0074] The above formulas are all dimensionless and numerical calculations. The formula is a formula obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
