Description

Technical Field

[0001] The utility model relates to the technical field of rat breeding and reproduction, in particular to a novel chlorine water reverse osmosis water supply system for an animal room. Background Art

[0002] In the experimental animal industry, especially in the breeding of mice and rats, there are three main types of drinking water for animals: sterile water, acidified water, and chlorinated water; these three types of drinking water can meet the daily needs of mice and rats.

[0003] There are generally two ways to produce sterile water: one is the more primitive method of using municipal pipe water for high-pressure sterilization and then directly entering the barrier system for animals to drink; the other is to filter and purify municipal pipe water (RO) and then enter the barrier system for animals to drink.

[0004] Acidified water is sterile water with hydrochloric acid (HCl) or sulfuric acid (H2SO4) adjusted to a pH of 2.5-3 for animal drinking. There are two specific methods for producing this water: one is to acidify municipal water to adjust the pH, sterilize it with an autoclave, and then feed it into the barrier system for animal drinking. The other is to purify municipal water (RO) and then add an automated acidification device to adjust the pH before feeding it into the barrier system for animal drinking.

[0005] Chlorinated water refers to adding sodium hypochlorite (Naclo) to the drinking water of animals, and adjusting the residual chlorine to 2.0-4.0ppm for drinking by animals.

[0006] Acidified and chlorinated water have a strong antibacterial effect on drinking water bacteria. Reports indicate that they can reduce rodent infections with opportunistic pathogens, a microbial indicator required by national standards for laboratory animals. Experiments comparing bacterial counts in the three types of water after use in animal rooms over a period of time revealed that chlorinated water exhibited a longer antibacterial effect. Furthermore, literature indicates that low concentrations of acidification and chlorination do not pose a health risk to animals.

[0007] For production units, the animals supplied must meet national standards, which is a prerequisite for ensuring the safety of the barrier system of downstream users and the accuracy of experimental data.

[0008] However, for rat and mouse production facilities that use autoclaved acidified water for drinking, the main challenges are the high steam demand of autoclaves. Even if steam is readily available in the facility, ensuring its availability is challenging. If steam is unavailable, installing a boiler in-house raises questions about boiler safety and record keeping. Another issue is the serious corrosion of autoclave acidification. Observational studies have shown that high-temperature acidification can severely corrode the sterilizer's internal cylinder, product carts, and piping. Repairing and replacing the sterilizer is a significant undertaking for the barrier system. Furthermore, whether the manually prepared acidified water can maintain a uniform and stable pH value is a significant concern. Utility Model Content

[0009] The purpose of this utility model is to address the shortcomings of the existing technology. For example, for rat and mouse production units that use autoclaved acidified water for drinking, the main problems they face are the high steam demand of the autoclave. Even if steam is available in the production area, it is difficult to ensure that steam is readily available. If steam is not available in the production area, installing a boiler in-house involves issues such as boiler safety and record keeping. Another problem is that autoclave acidic water is severely corrosive to the sterilizer. Actual observations show that high-temperature acidic water seriously corrodes the sterilizer's inner cylinder, product carts, and pipelines. Repairing and replacing the sterilizer is a relatively large project for the barrier system. Secondly, whether the manual preparation of acidified water can ensure a uniform and stable pH value is also a major problem. Therefore, a new chlorine water reverse osmosis water supply system for animal rooms is proposed.

[0010] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The pressure of the chlorine water during discharge is measured by the pressure gauge 710, and the connection between the pressure gauge 710 and the chlorine discharge pipe 712 is controlled by the fifth manual valve 711.

[0028] The liquid inlet of the chlorine water barrel 1, the liquid outlet of the second filter 708 and the liquid outlet of the third filter 709 are all connected to the third solenoid valve 11 through pipes. The circulation of chlorine water is achieved through the first delivery pump 706, the second delivery pump 707, the second filter 708, the third filter 709 and the third solenoid valve 11.

[0029] A liquid level gauge 12 is provided on the top of the chlorine water barrel 1, and an upper liquid level switch 13 and a lower liquid level switch 14 are provided on the side of the chlorine water barrel 1. The liquid level of the chlorine water in the chlorine water barrel 1 is measured by the liquid level gauge 12, the upper liquid level switch 13 and the lower liquid level switch 14. A residual chlorine probe 15 is provided inside the chlorine water barrel 1 to detect the residual chlorine content in the chlorine water barrel 1.

[0031] In the present invention, the quantitative preparation process of the animal room chlorine water reverse osmosis water supply system is as follows: first, the first solenoid valve 4 is opened, and the RO water passes through the RO water pipe 9, the first solenoid valve 4, the flow meter 3 and the first filter 2 in sequence into the chlorine water bucket 1. At the same time, the control unit 17 reads the data of the flow meter 3. When the set amount is reached, the first solenoid valve 4 is closed and the metering pump 5 is started. At this time, the metering pump 5 injects a certain amount of hypochlorous acid into the chlorine water bucket 1 according to the set program. Then, the second manual valve 701, the third manual valve 704 and the fourth manual valve 705 are manually opened, and the second solenoid valve 702 is opened by the control unit 17. , third solenoid valve 11, first delivery pump 706 and second delivery pump 707. At this time, the RO water and hypochlorous acid in the chlorine water barrel 1 are circulated through the first delivery pump 706 and the second delivery pump 707, and the RO water and hypochlorous acid in the chlorine water barrel 1 are mixed and stirred through the stirrer 16. At the same time, after mixing for a period of time, the free chlorine in the chlorine water barrel 1 is read by the residual chlorine probe 15, and hypochlorous acid is replenished to the set range of 2-4PPM based on the feedback value of free chlorine. When the liquid meets the set requirements, the user can manually open the fifth manual valve 711 as needed to discharge the chlorine water through the chlorine discharge pipe 712.

[0032] When RO water is added to the chlorine water barrel 1, if the flow meter 3 does not reach the measured value and the upper liquid level switch 13 alarms, the control unit 17 will automatically cut off the first solenoid valve 4 to prevent overflow. At this time, the metering pump 5 will also be locked.

[0033] When discharging chlorine water, if the lower liquid level switch 14 sounds an alarm, the control unit 17 will automatically cut off the second solenoid valve 702, the first delivery pump 706 and the second delivery pump 707 to avoid emptying.

[0034] When the amount of chlorine water used is small, only the first delivery pump 706 is started to deliver, and the outlet pressure is maintained by frequency conversion. When the first delivery pump 706 is at full speed and the pressure is still insufficient, the second delivery pump 707 is automatically started to make up the amount. At this time, the first delivery pump 706 runs at the industrial frequency, and the second delivery pump 707 is frequency-controlled to control the pressure.

[0035] The online preparation process of the animal room chlorine water reverse osmosis water supply system is as follows: first, a certain amount of chlorine water is prepared using a quantitative preparation method, and then the liquid is discharged through the drainage pipe 7. At the same time, the first solenoid valve 4 is opened to perfuse RO water, and the metering pump 5 is controlled according to the data of the flow meter 3 to synchronously add a certain amount of hypochlorous acid and complete uniform mixing in the chlorine water bucket 1. At the same time, according to the reading of the residual chlorine probe 15, the ratio value is corrected in real time to control the residual chlorine value reading within the set range.

[0036] When the upper liquid level switch 13 sounds an alarm, indicating that the liquid level in the chlorine water tank 1 is full, the control unit 17 closes the first solenoid valve 4 and the metering pump 5, and stops adding RO water and hypochlorous acid. After a period of time after the alarm signal of the upper liquid level switch 13 is removed, the first solenoid valve 4 is opened again, and the metering pump 5 is controlled at the same time to prevent the tank from overflowing.

[0037] When the lower liquid level switch 14 sounds an alarm, it indicates that the liquid level has fallen below a safe position, and the control unit 17 closes the second solenoid valve 702, the first delivery pump 706, and the second delivery pump 707 to avoid vacuum.

[0038] In this way, the supply to the next process is continuous, but the prepared chlorine water will fluctuate within a certain range.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
