Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality monitoring technology, specifically a flushing device for a water quality monitoring instrument. Background Technology
[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural waters, as well as various types of industrial wastewater.
[0003] CN220872464U discloses a self-cleaning online water quality monitoring device, belonging to the field of water quality monitoring technology. It includes a water quality monitor body with a mounting rod rotatably mounted on its back. A fixing plate is fixedly mounted on the end of the mounting rod away from the water quality monitor body, and a movable plate is provided on the side of the fixing plate. A cleaning brush is used in conjunction with a water quality sensor. When the water quality sensor is monitoring water quality data, a motor drives an upper connecting plate to rotate through the meshing of gears one and two. This, in turn, drives the mounting plate to rotate the cleaning brush under the connection of the connecting plate and the lower connecting plate. This allows for surface cleaning of the water quality sensor using the rotation of the cleaning brush, effectively preventing surface dirt from affecting monitoring. It also eliminates the need for regular cleaning by personnel, improving work efficiency. Furthermore, the cleaning brush can be easily installed and removed using springs and locking blocks. However, this mechanical friction cleaning method can only clean the detection head and cannot clean pipes and pumps. Generally, deionized water rinsing is required for cleaning, and after cleaning, deionized water residue remains in the water quality monitor. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a water quality monitor rinsing device, which solves the problem of residual cleaning water when cleaning water quality monitors.
[0005] Technical solution
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a water quality monitor flushing device, including a multi-way inlet valve installed at the inlet end of the water quality monitor, and an electromagnetic tee installed at the outlet end of the water quality monitor. The cleaning inlet of the multi-way inlet valve is connected to and passes through a reversing tee. One end of the reversing tee is connected to and passes through a deionized water inlet pipe, and the other end of the reversing tee is connected to and passes through a drying gas inlet pipe. The end of the drying gas inlet pipe away from the reversing tee is connected to and passes through a drying gas supply unit.
[0007] Furthermore, the drying gas supply unit includes a high-pressure gas cylinder, the interior of which contains compressed gas.
[0008] Furthermore, the drying gas supply unit includes an induced draft fan, and a filter unit is provided at the inlet end of the induced draft fan.
[0009] Furthermore, a disinfection chamber is provided between the drying gas supply unit and the drying gas inlet pipe.
[0010] Furthermore, the outer surface of the dry gas inlet pipe is provided with a heat tracing tape that wraps around the dry gas inlet pipe.
[0011] Furthermore, the disinfection chamber includes an outer shell, and an ultraviolet irradiation lamp is installed inside the outer shell.
[0012] Furthermore, the disinfection chamber includes a mixing chamber, one end of which is connected to and penetrates an ozone supply pipe, and a high-temperature decomposition chamber is provided between the mixing chamber and the dry gas inlet pipe.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The water quality monitor flushing device is configured to use a deionized water inlet pipe connected to a multi-inlet valve to flush and clean the water quality monitor. Then, it switches to a dry gas inlet pipe connected to the multi-inlet valve to ventilate the water quality monitor with dry gas, thereby drying the deionized water used for cleaning and keeping the water quality monitor clean.
[0015] 2. The flushing device of this water quality monitor includes a disinfection chamber comprising a mixing chamber. The mixing chamber is equipped with a labyrinth seal to increase the gas residence time. One end of the mixing chamber is connected to and has an ozone supply pipe through it, which disinfects the gas through ozone. A high-temperature decomposition chamber is set between the mixing chamber and the dry gas inlet pipe. The high-temperature decomposition chamber has two functions: first, to decompose the ozone into oxygen at high temperature; second, to heat the gas. This design can disinfect the gas and prevent bacteria and microorganisms from entering the water quality monitor. Attached Figure Description

[0023] See Figure 1-5 A water quality monitor flushing device includes a multi-way inlet valve 1 installed at the inlet end of the water quality monitor and an electromagnetic tee 2 installed at the outlet end of the water quality monitor. The cleaning inlet of the multi-way inlet valve 1 is connected to and passes through a reversing tee 3. One end of the reversing tee 3 is connected to and passes through a deionized water inlet pipe 4, and the other end of the reversing tee 3 is connected to and passes through a drying gas inlet pipe 5. The end of the drying gas inlet pipe 5 away from the reversing tee 3 is connected to and passes through a drying gas supply unit 6. With this configuration, the water quality monitor can first be cleaned with deionized water, and then the water quality monitor can be dried by introducing drying gas, thereby completing the flushing of the water quality monitor.
[0024] The dry gas supply unit 6 includes a high-pressure gas cylinder 601, which contains compressed gas. Generally, the compressed gas is nitrogen, which has a low cost of obtaining and can ensure the cleanliness and dryness of nitrogen during industrial compression.
[0025] The dry gas supply unit 6 includes an induced draft fan 602, and a filter unit 603 is provided at the inlet end of the induced draft fan 602. The filter unit 603 includes multiple layers, including at least the filtration of moisture and impurities.
[0026] A disinfection chamber 64 is provided between the dry gas supply unit 6 and the dry gas inlet pipe 5. By setting up the disinfection chamber 64, the gas is disinfected through the internal disinfection mechanism, thereby preventing bacteria and microorganisms from entering the water quality monitor.
[0027] The outer surface of the dry gas inlet pipe 5 is provided with a heat tracing cable 605 that wraps around the dry gas inlet pipe 5. The dry gas can be heated by the heat tracing cable 605.
[0028] The disinfection chamber 64 includes an outer shell 641, and an ultraviolet lamp 642 is installed inside the outer shell 641. The ultraviolet lamp 642 can disinfect the passing gas.
[0029] The disinfection chamber 64 includes a mixing chamber 643, which is equipped with a labyrinth sealing plate to increase the gas residence time. One end of the mixing chamber 643 is connected to and passes through an ozone supply pipe 644, which disinfects the gas through ozone. A high-temperature decomposition chamber 645 is set between the mixing chamber 643 and the dry gas inlet pipe 5. The high-temperature decomposition chamber 645 has two functions: first, to decompose the ozone at high temperature and convert it into oxygen; second, to heat the gas.
[0030] In use, the multi-port valve 1 can connect different reagents and cleaning liquids to the water quality monitor. When cleaning is required, the deionized water inlet pipe 4 is first connected to the multi-port valve 1 to flush and clean the water quality monitor with deionized water. Then, the dry gas inlet pipe 5 is connected to the multi-port valve 1 to ventilate the water quality monitor with dry gas, thereby drying the deionized water used for cleaning and keeping the water quality monitor clean.
