Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a water quality monitoring device capable of adding medicine. Background Art

[0002] Water quality monitors are instruments for monitoring natural water, which can be polluted or unpolluted. Factory-polluted wastewater is discharged into rivers. First, it is necessary to treat the wastewater by adding chemicals and other steps. It can only be discharged when it meets the standards. This requires that the wastewater treated with experimental chemicals meet the discharge standards. In order to improve the discharge efficiency, existing water quality monitoring devices usually add drugs during monitoring to purify and discharge the wastewater in the water quality monitoring device.

[0003] For example, an existing patent (publication number: CN207601071U) discloses a water quality monitoring device that can add medicine. The device has a simple structure and is easy to use. It can add medicine to monitor water quality. The medicine barrel facilitates the addition of medicine, and the scale line accurately measures the amount of the medicine.

[0004] However, the above-designed water quality monitoring device with dosing still has some shortcomings in practical applications: although the water quality monitoring device with dosing is provided with a scale line, so as to facilitate the accurate control of the dosing metering, this method requires manual operation, that is, manual reference to the scale line to control the dosing metering. Manual operation is not only time-consuming and labor-intensive, but also prone to operating errors leading to over-addition or under-addition. For this reason, we designed a water quality monitoring device with dosing to solve the above problems. Utility Model Content

[0005] The utility model provides a water quality monitoring device capable of adding medicine. By connecting a waste water pipe to a water inlet pipe and opening a first electromagnetic valve, waste water can be conveniently injected into a detection tank. During this process, as more and more waste water is in the detection tank, the detection tank will compress the first spring and move downward. When the detection tank abuts against a trigger component, the trigger component will close the first electromagnetic valve and open the second electromagnetic valve, so that medicine in a medicine storage box is injected into the detection tank through a connecting pipe. As more and more medicine is injected into the detection tank, the detection tank will continue to descend. When a contact block abuts against the first electromagnetic button, the first electromagnetic button can automatically close the second electromagnetic valve, so that the medicine storage box stops adding medicine. At this time, medicine of appropriate measurement is just put into the detection tank. The above process has less manual participation, which not only reduces the work intensity of the personnel, but also helps to solve the problem of adding too much or too little medicine due to manual error, and solves the technical problems raised in the above background technology.

[0022] The trigger assembly includes a slide plate 12, a first hemisphere 13, a touch rod 15, a second electromagnetic button 16 and a second spring 17. The slide plate 12 is slidably arranged in the tank body 1. The first hemisphere 13 is arranged on one side of the slide plate 12. A second hemisphere 14 is arranged at the bottom of one side of the detection tank 2. The second hemisphere 14 cooperates with the first hemisphere 13 to abut against each other. The touch rod 15 is arranged on the other side of the slide plate 12. A second electromagnetic button 16 is arranged in the tank body 1. The touch rod 15 cooperates with the second electromagnetic button 16 to abut against each other. The second electromagnetic button 16 is electrically connected to the first electromagnetic valve 6 and the second electromagnetic valve 9. A second spring 17 is arranged on one side of the slide plate 12. The other end of the second spring 17 is connected to the tank body 1. A slide groove 18 is opened in the tank body 1. The slide plate 12 is slidably connected in the slide groove 18. The second electromagnetic button 16 is fixedly installed on the inner side wall of the slide groove 18. The two ends of the second spring 17 are respectively fixedly connected to the slide plate 12 and the inner side wall of the slide groove 18.

[0023] During the specific implementation, the waste water pipe is connected to the water inlet pipe 5, and then the first solenoid valve 6 is opened to allow the waste water to be injected into the detection tank 2 through the water inlet pipe 5. During this process, as the waste water in the detection tank 2 increases, the detection tank 2 will compress the first spring 3 to move downward.

The above process requires less manual participation, which not only reduces the workload of the personnel, but also helps to solve the problem of adding too much or too little medicine due to human errors.

[0024] Embodiment 2

[0025] Depend on Figure 1-3 A water quality monitoring device capable of adding medicine is provided, comprising a tank body 1, a detection tank 2 is movably arranged in the tank body 1, two first springs 3 and a telescopic rod 4 are symmetrically arranged at the bottom of the detection tank 2, the other ends of the first spring 3 and the telescopic rod 4 are fixedly connected to the inner bottom wall of the tank body 1, a water inlet pipe 5 is fixedly plugged into the top of one side of the tank body 1, a first solenoid valve 6 is arranged on the water inlet pipe 5, a medicine storage box 7 is arranged on the side of the tank body 1 away from the water inlet pipe 5, medicine is added in the medicine storage box 7, a connecting pipe 8 is fixedly plugged into one side of the medicine storage box 7, the other end of the connecting pipe 8 extends into the tank body 1, a second solenoid valve 6 is arranged on the connecting pipe 8 Valve 9, a contact block 10 is provided at the bottom of the detection tank 2, a first electromagnetic button 11 is provided on the bottom wall of the tank body 1, the contact block 10 and the first electromagnetic button 11 are matched and abutted against each other, the first electromagnetic button 11 is electrically connected to the second electromagnetic valve 9, a trigger component is also provided in the tank body 1, the trigger component is electrically connected to the first electromagnetic valve 6 and the second electromagnetic valve 9, a water quality detector 26 is provided in the detection tank 2, a stirring shaft 19 is rotatably provided in the tank body 1, a plurality of stirring rods 20 are provided on both sides of the stirring shaft 19, a motor 21 is provided on the top of the tank body 1, and a driving shaft of the motor 21 is transmission-connected to one end of the stirring shaft 19.

[0026] In specific implementation, based on the above embodiment 1, during the fusion of wastewater and medicine, the motor 21 is turned on, so that the stirring shaft 19 drives the stirring rod 20 to move and stir the medicine and wastewater, which accelerates the fusion of the medicine and thus speeds up the rate of purifying the wastewater.

[0027] A water outlet pipe 22 is fixedly connected to the bottom of one side of the detection tank 2, and a faucet 23 is provided at one end of the water outlet pipe 22. A sliding hole 24 is provided on one side of the tank body 1, and the water outlet pipe 22 is slidably connected in the sliding hole 24. When the water quality detector 26 detects that the wastewater quality in the detection tank 2 meets the standard, the faucet 23 is opened at this time to discharge the water.

[0028] A controller 25 is disposed on the front side of the tank body 1 , and the controller 25 is electrically connected to the motor 21 , so that personnel can conveniently control the switch of the motor 21 .

[0029] As for the controller 25, by operating the controller 25, the controller 25 can send an electrical signal to the motor 21 and activate it, thereby achieving the purpose of conveniently controlling the motor 21. Since the controller 25 is a prior art, it will not be described in detail in this specification.

[0030] For the water quality detector 26, PP cotton microporous filtration technology is usually adopted (mainly filtering mud, rust, red worms and other tiny substances), and the water quality detector 26 is set in the wastewater. According to the different water quality, the white filter element of the water quality detector 26 can be seen to change color after different water discharge times, so as to judge whether the wastewater meets the standards. Since the water quality detector 26 is a prior art, it will not be explained in detail in this manual.

[0031] The first solenoid valve 6 and the second solenoid valve 9 are gate valves usually controlled by electromagnetics. The flow direction of the gate valve is perpendicular to the direction of the fluid. The solenoid gate valve can only be fully opened and fully closed. The principle is: when power is turned on, the solenoid valve coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens. When power is turned off, the electromagnetic force disappears, and the elastic force presses the closing member onto the valve seat, and the valve closes. Since the first solenoid valve 6 and the second solenoid valve 9 belong to the prior art, they will not be described in detail in this manual.

[0032] In addition, for the first electromagnetic button 11 and the second electromagnetic button 16, a circuit, a trigger block and a spring are usually arranged inside, and the trigger block is connected to the spring. When the trigger block is pressed, the spring can be connected to the circuit to form a loop, and an electrical signal can be sent to the connected electrical appliance to activate it, thereby achieving the purpose of facilitating the control of the electrical appliance. Since the first electromagnetic button 11 and the second electromagnetic button 16 are both existing technologies, they will not be described in detail in this manual.

[0033] Working principle:

[0034] When in use, firstly, all the electrical appliances involved in the water quality monitoring device are connected to an external power supply, and then the waste water pipe is connected to the water inlet pipe 5, and then the first solenoid valve 6 is opened to allow waste water to be injected into the detection tank 2 through the water inlet pipe 5. During this process, as the waste water in the detection tank 2 increases, the detection tank 2 will compress the first spring 3 to move downward. When the second hemisphere 14 abuts against the first hemisphere 13 and pushes the slide plate 12 to compress the second spring 17 to drive the touch rod 15 to abut against the second solenoid button 16, the second solenoid button 16 will send an electrical signal to the first solenoid valve 6 to close it. At this time, the water in the water inlet pipe 5 stops draining to prevent waste water from overflowing from the detection tank 2. In addition, the second solenoid button 16 will also open the second solenoid valve 9 according to the above principle, so that the medicine in the medicine storage box 7 is injected into the detection tank through the connecting pipe 8. In the test tank 2, as more and more medicine is injected into the test tank 2, the test tank 2 will continue to drop. When the contact block 10 abuts against the first electromagnetic button 11, the first electromagnetic button 11 sends an electrical signal to the second electromagnetic valve 9 and closes it, so that the medicine storage box 7 stops releasing medicine. At this time, the test tank 2 is just filled with a suitable amount of medicine. The above process requires less manual participation, which not only reduces the workload of personnel, but also helps to solve the problem of adding too much or too little medicine due to human error. Then, the motor 21 is turned on to make the stirring shaft 19 drive the stirring rod 20 to move and stir the medicine and wastewater, which accelerates the fusion of the medicine, thereby accelerating the rate of purifying the wastewater. When the water quality detector 26 detects that the quality of the wastewater in the test tank 2 meets the standard, the faucet 23 is turned on to drain the water.
