Description

Technical Field

[0001] The utility model relates to the technical field of direct drinking water equipment, in particular to direct drinking water equipment with an intelligent regulating function. Background Art

[0002] Direct drinking water, also known as healthy living water, refers to water that is directly drinkable and meets these three conditions: no pollution, no degradation, in line with human physiological needs (contains beneficial mineral elements similar to the human body), and has a weakly alkaline pH value. At present, the deep treatment of domestic direct drinking water equipment mainly uses a single membrane group for purification, such as reverse osmosis, nanofiltration, ozone or ultraviolet disinfection.

[0003] At present, there are many commercial direct drinking water equipment on the market, and they have certain automatic adjustment functions. For example, the equipment shown in patent publication number CN216005404U already has preliminary intelligent adjustment functions, and its intelligent control system is connected with the pretreatment system and the deep treatment system; wherein, the deep treatment system includes a primary treatment system and a secondary treatment system, and part of the raw water after pretreatment by the pretreatment system enters the primary treatment system, and the other part enters the secondary treatment system for reprocessing; the primary treatment system is used for deep treatment of the raw water after pretreatment.

[0004] However, some flow monitoring of direct drinking water equipment in the above technical solution adopts rotor flowmeter, which cannot monitor the flow abnormality of the equipment in real time and relies on manual inspection. In addition, the flushing of the sand filter tank is regular, and the time is an empirical value. There is no clear data judgment basis. This solution makes a scientific judgment based on the pressure before and after the sand filter tank, and intelligently adjusts the cleaning time through the pressure difference. At the same time, it is considered that the high circulating water pressure will affect the flushing effect. Therefore, the utility model solves the shortcomings of the above technical problems.

[0019] 2. The sand filter and carbon filter tanks of existing direct drinking water equipment are flushed regularly, and the time is an empirical value. There is no clear data basis for judgment. This solution makes a scientific judgment based on the pressure before and after the sand filter tank, and intelligently adjusts the cleaning time through the pressure difference.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 5 A direct drinking water device with intelligent adjustment function includes two sand filter tanks 1 for preliminary filtering of direct drinking water, a connecting pipe 2 is arranged between the two sand filter tanks 1, a water supply system is arranged on one side of the sand filter tank 1, and the water supply system is composed of a support frame and a first reverse osmosis membrane filter 3, a second reverse osmosis membrane filter 4, an ultrafiltration membrane filter 5, a multi-media filter 6, an activated carbon filter 7, and a precision filter 8 installed on the surface of the support frame. A buffer mechanism is arranged on one side of the connecting pipe 2, and the buffer mechanism buffers the high-pressure water flow entering the connecting pipe 2, and the buffer mechanism includes a temporary water storage tank 9.

[0029] The outer surfaces of the flow tubes of the first reverse osmosis membrane filter 3, the second reverse osmosis membrane filter 4 and the ultrafiltration membrane filter 5 are provided with a post-membrane pressure gauge 10 and a membrane pressure gauge 11. The raw water is filtered by using the filter membrane types in two different filters to treat the water quality, and then the effluent is mixed to meet the target water quality requirements. Among them, the effluent water of the ultrafiltration membrane in the ultrafiltration membrane filter 5 will retain all the minerals, trace elements and hardness of the raw water, and the pH value of its effluent is the same as that of the raw water, while the reverse osmosis membranes in the first and second reverse osmosis membrane filters will filter out all the minerals, trace elements and hardness in the water, and the PH value of its effluent is weakly acidic. In actual use, the mixing ratio of the first-level direct drinking water and the second-level direct drinking water can be controlled as needed, and the minerals and hardness in the effluent water can be adjusted to the desired range. The working conditions of the three filter membranes can be inferred according to the real-time post-membrane pressure gauge 10 and the membrane pressure gauge 11, and timely reminders can be given to replace the filter membranes.

[0030] A water flow sensor 13 is provided on the water flow pipe between the sand filter tank 1, the first reverse osmosis membrane filter 3, the second reverse osmosis membrane filter 4, the ultrafiltration membrane filter 5, the multi-media filter 6, the activated carbon filter 7 and the precision filter 8. The water flow sensor 13 can calculate the instantaneous flow rate and the cumulative flow rate, and monitor whether the equipment is operating normally through comprehensive analysis with the pressure value.

[0031] Some flow monitoring of existing direct drinking water equipment uses rotor flow meters, which cannot monitor the flow abnormalities of the equipment in real time and rely on manual inspections. This technical solution uses an electronic flow meter, which can obtain the required flow in real time and monitor abnormalities based on the obtained flow.

[0032] A front-tank pressure sensor 15 and a rear-tank pressure sensor 14 are added before and after the sand filter tank 1, and whether backwashing is needed is determined according to the pressure difference. In order to avoid the high-pressure water flow rate being too fast and reducing the backwashing effect, the buffer mechanism also includes two rear-tank pressure sensors 14 fixedly installed on the outer surface of the connecting pipe 2. The front-tank pressure sensor 15 is arranged on the outlet pipe of the sand filter tank 1, and a drain pipe 16 with an inclined distribution and a solenoid valve is fixedly connected to one side of the middle part of the connecting pipe 2. When one of the rear-tank pressure sensors 14 detects the high-pressure water flow, the solenoid valve on the drain pipe 16 opens to divert the high-pressure water flow to the drain pipe 16 to reduce the water pressure.

[0033] The sand filter and carbon filter tanks of existing direct drinking water equipment are flushed regularly, and the time is an empirical value. There is no clear data basis for judgment. This solution makes a scientific judgment based on the pressure before and after the sand filter tank 1, and intelligently adjusts the cleaning time through the pressure difference.

[0034] In order to divert the water flow in the drain pipe 16 and buffer the water pressure, the buffer mechanism also includes a sealing block 17 fixedly connected to one side of the drain pipe 16, one side of the sealing block 17 is fixedly connected to the surface of one side of the temporary water storage tank 9, and the interior of the sealing block 17 is symmetrically distributed with Tesla valve cavities 18, and the two ends of the Tesla valve cavity 18 are respectively fixedly connected to the drain pipe 16 and the interior of the temporary water storage tank 9. The water flow in the drain pipe 16 flows into the Tesla valve cavity 18 of the sealing block 17. The unique hedging characteristics of the continuous bend of the Tesla valve cavity 18 can be used to buffer the water flow and prevent impurities from being precipitated when the water flow is left standing. In order to further buffer the water pressure in the connecting pipe 2, the water flow in the Tesla valve cavity 18 is diverted to the temporary water storage tank 9 for storage.

[0035] In order to prevent the water temporarily stored in the temporary water storage tank 9 from standing still for a long time, a liquid level sensor 19 is installed on the upper surface of the temporary water storage tank 9, and a water inlet pipe 20 with a solenoid valve is fixedly connected to the lower surface of the temporary water storage tank 9. One end of the water inlet pipe 20 is fixedly connected to the inside of the connecting pipe 2. The liquid level in the temporary water storage tank 9 is monitored by the liquid level sensor 19 to prevent static sedimentation. In order to flush the liquid in the temporary water storage tank 9, the liquid is discharged to the connecting pipe 2 through the water inlet pipe 20. At this time, the pressure is detected by the pressure sensor 14 after another tank.

[0036] By setting a buffer mechanism, the high water pressure in the connecting pipe 2 between the sand filter tanks 1 can be buffered. During the adjustment process, the water flow in the drain pipe 16 flows into the Tesla valve cavity 18 of the sealing block 17. The unique offset characteristics of the continuous bend pipe of the Tesla valve cavity 18 can be used to buffer the water flow, thereby avoiding the high-pressure water flow speed being too fast and reducing the backwashing effect.

[0037] Working principle: In a specific embodiment of the utility model, the direct drinking water is flushed through the sand filter tank 1. When the pressure sensor 14 behind one of the tanks detects the high-pressure water flow, the solenoid valve on the drain pipe 16 opens, and the high-pressure water flow in the connecting pipe 2 is diverted to the drain pipe 16. The water flow in the drain pipe 16 flows to the Tesla valve cavity 18 of the sealing block 17. The unique offset characteristics of the continuous bend pipe of the Tesla valve cavity 18 can be used to buffer the water flow. The buffered water flow is drained to the temporary water storage tank 9 for storage, and the liquid level in the temporary water storage tank 9 is monitored by the liquid level sensor 19. Then the water inlet pipe 20 discharges the liquid to the connecting pipe 2 again. At this time, the pressure is detected by the pressure sensor 14 behind another tank until the flushing water pressure is reached.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
