DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: a fully automatic water quality pretreatment unit, including a mounting frame 1, inside which an electric control box 2, a medicine box 3, a metering pump 4 and a detection pipeline 5 are fixedly installed, the electric control box 2, the medicine box 3 and the metering pump 4 are arranged in the upper, middle and lower layers and fixed in the mounting frame 1, the detection pipeline 5 is a U-shaped structure, and the detection pipeline 5 is fixedly arranged at the lower side of the metering pump 4.

[0021] Both ends of the detection pipe 5 extend to the rear side of the mounting frame 1, and the two ends of the detection pipe 5 are respectively a water inlet 6 and a water outlet 7. A back pressure valve 8 and a thermal conductivity flow meter 9 are fixedly installed on the surface of one end of the detection pipe 5 close to the water outlet 7. The outlet end of the metering pump 4 is connected with the back pressure valve 8 through a pipeline, and the bottom of the medicine box 3 is connected with the inlet end of the metering pump 4 through a pipeline. A dosing port 10 is provided on the upper side of the medicine box 3, and a liquid level meter 11 is installed inside the medicine box 3.

[0022] A dosing window is provided on the side of the mounting frame 1, and a dosing door panel 17 is hingedly installed at the dosing window. A detachable front door panel 18 is fixed on the front of the mounting frame 1 by bolts. The control panel 12 extends to the front side of the mounting frame 1, and the control panel 12 is located on the upper side of the front door panel 18.

[0023] A control panel 12 is fixedly mounted on the front of the electric control box 2 , and a power indicator light 13 , an operation indicator light 14 , a device switch 15 and an alarm buzzer 16 are respectively provided on the surface of the control panel 12 .

[0024] Among them, a heater 19 is fixedly installed on the bottom of the medicine box 3, and the heater 19 is electrically connected to the electric control box 2. An Internet of Things module 20 is fixedly installed on the side of the medicine box 3, and the electric control box 2 is electrically connected to the Internet of Things module 20.

[0025] Operation principle: After the device is connected to the power supply, power is supplied and the power indicator light 13 is observed to be lit. After it is lit, the device switch 15 is rotated to start the device. When the device is running, the operation indicator light 14 is lit to display the operation.

[0026] The water inlet 6 is connected to the system water supply pipe, and the water outlet 7 is connected to the system water tank. The water supply enters the detection pipe 5 in the equipment through the water inlet 6. The thermal conductivity flowmeter 9 in the equipment detects the water flow and sends a signal to the metering pump 4. The metering pump 4 fills the medicine according to the set parameters. During the filling, the metering pump 4 sucks the medicine in the medicine box 3, and the medicine enters the metering pump 4 through the connecting pipe. Then, the metering pump 4 is filled into the detection pipe 5 through the back pressure valve 8 through the liquid outlet pipeline of the metering pump 4 to complete the medicine filling. The internal structure of the back pressure valve 8 can effectively prevent the liquid in the detection pipe 5 from flowing back into the medicine box 3 during the addition of the medicine, and can also prevent the siphoning of the medicine and the excessive amount of medicine from entering the system.

[0027] When the medicine in the medicine box 3 is insufficient, the liquid level meter 11 feeds back a signal to the electric control box 2, which issues a command, and the alarm buzzer 16 starts to alarm, and at the same time stops the metering pump 4 to stop the medicine filling.

[0028] Open the dosing door 17 and add the medicine through the dosing port 10. After the medicine is added, the liquid level meter 11 detects the liquid level signal and feeds it back to the electric control box 2. The alarm is automatically reset and the equipment is restored to operation.

[0029] An Internet of Things module 20 is installed inside the device, which can remotely monitor the operation of the device.

[0030] The fully automatic water quality pretreatment unit is configured with a metering pump 4 between the reagent box 3 and the detection pipe 5. The reagent is added into the detection pipe 5 by using the metering pump 4. The thermal conductivity flowmeter 9 detects the change of the water flow parameter in the detection pipe 5 and feeds back to the metering pump 4, so that the metering pump 4 adjusts the dosage ratio of the reagent according to the feedback data, thereby realizing the functions of real-time monitoring and adjustment.

[0031] By setting a liquid level meter 11, the remaining medicine in the medicine box 3 is monitored in real time. The feedback signal of the liquid level meter 11 triggers the alarm buzzer 16 to alarm, and timely reminds manual intervention. By setting a back pressure valve 8, the internal structure of the back pressure valve 8 can effectively prevent the liquid in the detection pipeline 5 from flowing back into the medicine box 3 during drug addition, and can prevent the siphoning of medicine and excessive medicine from entering the system, thereby improving the reliability of medicine filling.
