Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, and more specifically, to an intelligent ozone dosing device for a pipeline direct drinking water system. Background Art

[0002] The piped drinking water system uses a central water purification process to deeply treat tap water. The water quality meets the user's drinking and national requirements, and is transported to water points through an independent pipe network for users to drink. In order to ensure the safety of users' drinking water, the piped drinking water system adopts a number of measures such as 304 stainless steel pipe network, disinfection treatment, and membrane deep treatment. Among them, disinfection treatment plays a vital role as the last barrier to water production. The disinfection measures for piped drinking water systems on the market are mostly ozone disinfection, ultraviolet disinfection, and multiple combined disinfection (ozone + ultraviolet), among which ozone disinfection is used as the main disinfection measure. However, the ozone dosing devices on the market currently have a single working mode, the dosing effect is not guaranteed, and the ozone water taste of some dosing devices affects the user's drinking taste. Therefore, there is an urgent need for an intelligent ozone dosing device suitable for piped drinking water systems. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent ozone dosing device for a piped direct drinking water system, comprising a water-making main unit, a water supply pipe is fixedly connected to the right side of the water-making main unit, a connecting pipe is arranged at the top of the water supply pipe, an electric valve is fixedly installed at the bottom of the connecting pipe, an ejector is fixedly installed at the top of the connecting pipe, an ozone generator is arranged at the top of the ejector, a solenoid valve is fixedly connected to the top of the water supply pipe, an online ozone detection instrument is fixedly connected to the top of the solenoid valve, and a PLC controller is arranged on the rear side of the water-making main unit.

[0005] As a preferred technical solution of the utility model, a water inlet pipe is fixedly installed on the left side of the water-making main unit, and an activated carbon filter is fixedly installed in the middle of the water inlet pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model sets the water-making host to high-frequency water supply period and low-frequency water supply period through the PLC controller. During the low-frequency water supply period, the opening degree of the electric valve increases, and the flow rate in the inner cavity of the water supply pipe increases. When water flows out of the connecting pipe, the negative pressure of the ejector on the ozone generator increases, thereby increasing the amount of ozone added, thereby realizing high-intensity disinfection during the low-frequency water supply period, and detecting the ozone content inside the water supply pipe through an online ozone detection instrument, and setting an upper limit and a lower limit.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 4 As shown, the utility model provides an intelligent ozone dosing device for a pipeline direct drinking water system, comprising a water making main unit 1, a water supply pipe 2 is fixedly connected to the right side of the water making main unit 1, a connecting pipe 4 is arranged at the top of the water supply pipe 2, an electric valve 3 is fixedly installed at the bottom of the connecting pipe 4, an ejector 5 is fixedly installed at the top of the connecting pipe 4, an ozone generator 6 is arranged at the top of the ejector 5, a solenoid valve 7 is fixedly connected to the top of the water supply pipe 2, an online ozone detection instrument 8 is fixedly connected to the top of the solenoid valve 7, and a PLC controller 12 is arranged at the rear side of the water making main unit 1;

[0020] The water-making host 1 is set to a high-frequency water supply period and a low-frequency water supply period through the PLC controller 12. During the low-frequency water supply period, the opening degree of the electric valve 3 increases, and the flow rate in the inner cavity of the water supply pipe 2 increases. When water flows out from the connecting pipe 4, the negative pressure of the ejector 5 on the ozone generator 6 increases, thereby increasing the amount of ozone added, thereby achieving high-intensity disinfection during the low-frequency water supply period, and the ozone content inside the water supply pipe 2 is detected by the online ozone detection instrument 8, and the upper limit and lower limit are set. When it is higher than the upper limit, the ozone generator 6 stops working to prevent ozone from affecting the user's drinking taste. When it is lower than the lower limit, the PLC controller 12 increases the opening degree of the electric valve 3 according to the gradient, thereby realizing intelligent ozone addition.

[0021] Among them, a water inlet pipe 11 is fixedly installed on the left side of the water production main unit 1, and an activated carbon filter 9 is fixedly installed in the middle of the water inlet pipe 11;

[0022] By connecting the water source to the water inlet pipe 11, the impurities in the water are first filtered through the activated carbon filter 9, which further improves the water purification effect, not only ensures the water quality, but also avoids the accumulation of impurities in the water in the inner cavity of the water making main unit 1 and the water supply pipe 2.

[0023] The connecting pipe 4 is connected to the inner cavity of the water supply pipe 2, and the connecting pipe 4 is curved;

[0024] The inner cavity of the connecting pipe 4 and the water supply pipe 2 is connected, so that during the low-frequency water supply period, water flows out of the connecting pipe 4 to increase the negative pressure of the ejector 5 on the ozone generator 6, thereby increasing the ozone dosage.

[0025] Among them, a support ring is fixedly installed on the top of the water production main unit 1, and the ozone generator 6 is fixedly sleeved in the support ring;

[0026] By providing the support ring, the ozone generator 6 can be fixedly mounted inside the support ring, and the ozone generator 6 is further supported by the support ring, thereby improving the stability of the ozone generator 6 during use.

[0027] Among them, the bottom end of the online ozone detection instrument 8 is fixedly connected with a round tube, and the round tube is connected with the inner cavity of the water supply pipe 2;

[0028] Through the circular tube at the bottom end of the online ozone detection instrument 8, water can pass through the circular tube, so that the online ozone detection instrument 8 can detect the ozone content of the water entering the circular tube.

[0029] Among them, a delivery pump 10 is fixedly installed on the left side of the water inlet pipe 11;

[0030] By setting the delivery pump 10 , water in the water source can be pumped out from the water inlet pipe 11 by starting the delivery pump 10 , and the pumped water can be transported along the water inlet pipe 11 through the activated carbon filter 9 to the inner cavity of the water production host 1 .

[0031] The working principle and use process of the utility model are as follows: firstly, the water source is connected to the water inlet pipe 11, then the delivery pump 10 is started to deliver the water along the water inlet pipe 11 to the water making main unit 1, and the water is filtered through the activated carbon filter 9 during the delivery process;

[0032] The PLC controller 12 presets the high-frequency water supply period of the water-making host 1 to be 6:00-24:00, and the rest of the time is the low-frequency water supply period. The preset value is subsequently corrected every 7 days according to the actual flow data of the user. The ozone generator 6, the electric valve 3 and the solenoid valve 7 are started and stopped synchronously. During the high-frequency water supply period, the opening degree of the electric valve 3 reaches 60%, and it is opened for 10 minutes every 4 hours; during the low-frequency water supply period, the opening degree of the electric valve 3 reaches 100%, and it is opened for 20 minutes every 4 hours;

[0033] During the low-frequency water supply period, due to the increase in the opening degree of the electric valve 3, the flow rate in the water supply pipe 2 increases, and the negative pressure suction of the ejector 5 on the ozone generator 6 increases when the ejector 5 flows out, thereby increasing the amount of ozone added and performing high-intensity disinfection. At the same time, the full-time solenoid valve 7 is synchronously opened to detect the ozone concentration in the water supply pipe 2, and the upper and lower limits of the ozone concentration are set in the PLC controller 12. When it is higher than the upper limit, the ozone generator 6 stops working to prevent ozone from affecting the user's drinking taste; when it is lower than the lower limit, the system will increase the opening degree of the electric valve 3 during the high-frequency water supply period by 5% as a gradient.
