Description

Technical Field

[0001] The utility model relates to the technical field of instrument cleaning devices, in particular to a water quality instrument cleaning device. Background Art

[0002] Water pump rooms are required to be equipped with water quality meters. These meters measure parameters such as turbidity and residual chlorine. These meters are typically online, providing real-time data. This means they must operate 24 / 7, with water samples constantly flowing through them. Consequently, the meter's piping and flow cell are susceptible to contamination by sample water, and yellowish-brown scale forms on the pipe walls and inner walls of the flow cell, necessitating regular cleaning.

[0003] Existing instrument cleaning work is usually performed manually by workers. When cleaning, the instrument pipeline and circulation pool must be disassembled first, and then they are repeatedly scrubbed with a slender small brush. At the same time, for some strongly adherent scale, they need to be soaked in citric acid detergent first and then repeatedly rinsed. The entire cleaning process is relatively cumbersome and time-consuming, resulting in high cleaning costs. Therefore, to address the above problems, a water quality instrument cleaning device is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a water quality meter cleaning device, which can quantitatively pump the medicine in the medicine barrel into the medicine mixing circulation pool through a peristaltic pump. During cleaning, the water inlet pipe continuously flows tap water into the medicine mixing circulation pool, and mixes with the medicine to form a cleaning liquid. The cleaning liquid will flow out from the water outlet pipe under the water pressure of the tap water in the water inlet pipe and enter the pipeline of the water quality meter. After soaking for a period of time, it will continue to flush with the pressure of the tap water itself until all the residual cleaning liquid flows out of the water quality meter, completing automatic cleaning. This solves the technical problem in the prior art that the instrument cleaning work is usually performed manually by workers, and the whole process is cumbersome and time-consuming, which leads to high cleaning costs.

During cleaning, the water inlet pipe 5 continuously flows tap water into the medicine mixing circulation pool 4, and mixes with the medicine to form a cleaning liquid. The cleaning liquid will flow out from the water outlet pipe 6 under the action of the water pressure of the tap water in the water inlet pipe 5 and enter the water quality meter pipeline. After soaking for a period of time, it will continue to flush using the pressure of the tap water itself until all the residual cleaning liquid flows out of the water quality meter, completing automatic cleaning.

[0025] like Figure 2 As shown, the input end of the peristaltic pump 3 is tightly connected to a drug extraction tube 31, the end of the drug extraction tube 31 is inserted into the medicine barrel 2 and tightly connected thereto, and the output end of the peristaltic pump 3 is tightly connected to a drug delivery tube 32, which is connected to the medicine mixing circulation pool 4 and extends to the upper part of the medicine mixing circulation pool 4. The above-mentioned structural form can constitute a complete drug extraction and delivery pipeline, and the medicine in the medicine barrel 2 is pumped into the medicine mixing circulation pool 4 through the peristaltic pump 3.

[0026] In order to improve the stability and safety of the cleaning device during the cleaning process, Figure 2 As shown, the drug delivery tube 32 is sealed with a drug dosing solenoid valve 33, which is a one-way valve that only allows the drug to flow from the peristaltic pump 3 to the drug-water mixing circulation pool 4. The above structure can prevent tap water from flowing into the peristaltic pump 3 and interfering with the normal operation of the peristaltic pump 3.

[0027] In addition, the water inlet solenoid valve 51 is sealed connected to the water inlet pipe 5, and the cleaning liquid output solenoid valve 61 is sealed connected to the water outlet pipe 6. The water inlet solenoid valve 51 and the cleaning liquid output solenoid valve 61 are both one-way valves, wherein the water inlet solenoid valve 51 only allows tap water to flow from the water inlet pipe 5 to the chemical solution mixing circulation pool 4, and the cleaning liquid output solenoid valve 61 only allows cleaning liquid to flow from the chemical solution mixing circulation pool 4 to the water outlet pipe 6. The water inlet solenoid valve 51 can prevent the cleaning liquid from flowing back into the tap water pipeline and polluting the tap water, and the cleaning liquid output solenoid valve 61 can seal the water outlet pipe 6 after cleaning is completed to ensure that the cleaning liquid will not flow out and pollute the water sample in the water quality meter.

[0028] like Figure 3 As shown, an inclined plate frame 11 is fixedly provided at the bottom of the wall-mounted back panel 1, and a support plate 12 is fixedly provided on one side of the inclined plate frame 11. The support plate 12 provides the necessary structural basis for the installation and placement of the medicine barrel 2. A pipe laying groove 13 is formed on the other side thereof, and the pipe laying groove 13 can facilitate the laying of pipelines.

[0029] Among them, the medicine barrel 2 is placed on the support plate 12, and citric acid medicine is stored inside it. A sealing cover 21 is opened at the opening of the medicine barrel 2, and the sealing cover 21 is tightly connected with a medicine extraction tube 31 and a ventilation tube 22, and a one-way ventilation valve 8 is provided on the end of the ventilation tube 22. When the medicine extraction tube 31 extracts the medicine, the air pressure in the medicine barrel 2 will decrease, and the ventilation tube 22 can simultaneously inhale the outside air to maintain the air pressure balance in the barrel.

[0030] like Figure 4 As shown, the one-way vent valve 8 includes a valve cylinder 81, one end of which is provided with a sleeve 82, and the other end is provided with an air hole. A plurality of air inlet grooves 83 are provided on the inner wall of the valve cylinder 81, and a sealing piece 84 that can cover the air hole is slidably provided in the valve cylinder 81. When the sealing piece 84 slides away from the air hole, the air can pass through the air hole and enter the barrel through the air inlet groove 83 to maintain air pressure balance.

[0031] In addition, a fixing ring 85 is fixedly provided in the valve cylinder 81, and the fixing ring 85 does not occupy the space of the air inlet groove 83. A sliding shaft 86 is slidingly provided on the fixing ring 85. The front end of the sliding shaft 86 is fixedly connected to the sealing piece 84, and a reset spring 87 is provided on the outer sleeve of the sliding shaft 86. When the peristaltic pump 3 is not working, the reset spring 87 will push the sealing piece 84 to reset and seal the air hole, thereby preventing the space inside the barrel from being directly connected to the external environment, thereby making the medicine in the medicine barrel 2 less likely to deteriorate.

[0032] The use principle and use process of this utility model:

[0033] The medicine in the medicine barrel 2 is quantitatively pumped into the medicine mixing circulation pool 4 by the peristaltic pump 3. During cleaning, the water inlet pipe 5 continuously flows tap water into the medicine mixing circulation pool 4, and mixes with the medicine to form a cleaning liquid. The cleaning liquid will flow out from the water outlet pipe 6 under the water pressure of the tap water in the water inlet pipe 5 and enter the pipeline of the water quality meter. After soaking for a period of time, it will be continuously flushed using the pressure of the tap water itself until all the residual cleaning liquid flows out of the water quality meter, completing automatic cleaning.

[0034] In addition, several valve bodies arranged on the pipeline can ensure the stable operation of the cleaning device. Among them, the dosing solenoid valve 33 can prevent tap water from flowing into the peristaltic pump 3 and interfering with the normal operation of the peristaltic pump 3. The water inlet solenoid valve 51 can prevent the cleaning liquid from flowing back into the tap water pipeline and causing pollution to the tap water. The cleaning liquid output solenoid valve 61 can seal the water outlet pipe 6 after cleaning is completed to ensure that the cleaning liquid will not flow out and pollute the water sample in the water quality meter.

[0035] In addition, the ventilation pipe 22 is equipped with a one-way ventilation valve 8. When the peristaltic pump 3 pumps the medicine, the air pressure in the medicine barrel 2 decreases, and the air pressure pushes the sealing piece 84 to slide away from the air hole. At this time, the air can pass through the air hole and enter the barrel through the air inlet groove 83 to maintain the air pressure balance. When the peristaltic pump 3 is not working, the return spring 87 will push the sealing piece 84 to return to the sealed air hole, preventing the space in the barrel from being directly connected to the external environment, thereby making the medicine in the medicine barrel 2 less likely to deteriorate.

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
