Description

Technical Field

[0001] The utility model relates to the technical field of ultrapure water machines, and more specifically to an ultrapure water machine for experiments in the chemical industry. Background Art

[0002] Ultrapure water machines use pretreatment, reverse osmosis technology, ultrapurification treatment and post-treatment methods to almost completely remove the conductive medium in the water, and remove the non-dissociated colloids, gases and organic matter in the water to a very low level of water treatment equipment. The resistivity of ultrapure water produced by ultrapure water machines should generally be greater than 10 megohms. Water above 10 megohms is called ultrapure water, and the output of high-quality ultrapure water can reach 18.25 megohms.

[0003] Due to the different water quality in different places, sometimes the water produced by the ultrapure water machine cannot immediately meet the target requirements. Therefore, the unqualified water produced in the early stage is usually directly discharged, resulting in a certain degree of waste. At the same time, if the water production is unqualified due to water quality fluctuations or equipment problems, if it is not discovered in time, the original qualified ultrapure water will be contaminated. Therefore, in order to solve this kind of problem, this patent modifies the ultrapure water machine.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the discharge of unqualified water causes waste, and the contaminated ultrapure water cannot be discharged; secondly, the water supply volume during the use of the device is difficult to control and is prone to overflow, which needs to be improved. In view of this, we propose an ultrapure water machine for experiments in the chemical industry. Utility Model Content

An electronic four-way press valve 9 is fixedly provided at the other end, an electronic valve 14 is fixedly provided at the top of the electronic four-way press valve 9, a valve core 15 is fixedly provided on the side wall of the inner cavity of the electronic four-way press valve 9, an unqualified pipeline 10 is fixedly provided on the top of the side wall of the valve core 15, a qualified pipeline 16 is fixedly provided in the middle of the side wall of the valve core 15, a sewage pipeline 17 is fixedly provided at the bottom of the side wall of the valve core 15, an ultrapure water tank 11 is fixedly provided at the other end of the qualified pipeline 16, and an ultrapure water inlet 13 is fixedly provided at the bottom of the side wall of the ultrapure water tank 11. The utility model inputs raw water to the pure water machine 5 through the raw water outlet 4, and ultra-purifies the raw water through the pure water machine 5. When the water is used, it is classified according to the water indicators. When the water quality is qualified, the electronic valve 14 presses the valve core 15 to the middle section so that the water flows directly through the qualified pipeline 16 into the ultrapure water tank 11. When the water quality is unqualified, the electronic valve 14 lifts the valve core 15 to the upper section so that the water flows through the unqualified pipeline 10 into the raw water storage tank 1, which is convenient for recycling. When the water quality is polluted, the electronic valve 14 presses the valve core 15 to the middle and lower section so that the water flows through the sewage pipeline 17 to be discharged.

[0022] Specifically, a float valve 2 is fixedly installed at the bottom of the outer wall of the raw water inlet 3, and a float level switch 12 is fixedly installed inside the ultrapure water tank 11, located on the inner wall of the qualified pipeline 16. The float valve 2 controls the amount of raw water entering the raw water inlet 3 to prevent overflow. After the qualified ultrapure water enters the ultrapure water tank 11, the float level switch 12 controls the amount of water produced. When the liquid level in the ultrapure water tank 11 falls below the lower float, the water machine starts water production, and when the water level reaches the upper float, the water machine stops water production.

[0023] Furthermore, an operation panel 6 is fixedly provided on the outer wall of the water purifier 5, and a power switch 18 is fixedly provided on the side wall of the operation panel 6. The power switch 18 is turned on by a staff to control the water purifier 5 to process raw water.

[0024] It is worth noting that a water pump 19 is provided on the outer wall of the ultrapure water outlet 7 , and the water pump 19 is electrically connected to an external power supply. When the water pump 19 is turned on, the ultrapure water is output to the electronic four-way pressing valve 9 .

[0025] It is worth noting that a parking groove 20 is provided at the bottom of the inner cavity of the electronic four-way push valve 9. The size and position of the parking groove 20 match the size and position of the valve core 15. When the water purifier 5 is deactivated, the valve core 15 is pressed into the parking groove 20 at the bottom end by the electronic valve 14, and all three passages are closed.

[0026] In addition, a pad 22 is fixed to the bottom of the water purifier 5, and the material of the pad 22 is nitrile rubber. The pad 22 made of nitrile rubber improves the stability of the water purifier 5 during chemical industry experiments.

[0027] In addition, the circuits, electronic components, and modules involved in this utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the internal structure and method.

[0028] The device or equipment models involved in this article are as follows:

[0029] The model of the water pump 19 can be: IS65-50-160.

[0030] Working principle: When the device is needed to conduct ultrapure water machine chemical industry experiments, raw water is input to the pure water machine 5 through the raw water outlet 4, and the raw water is ultrapurified by the pure water machine 5. When in use, it is classified according to the incoming water indicators. When the water quality is qualified, the electronic valve 14 presses the valve core 15 to the middle section so that the water flows directly through the qualified pipeline 16 into the ultrapure water tank 11. When the water quality is unqualified, the electronic valve 14 lifts the valve core 15 to the upper section so that the water flows through the unqualified pipeline 10 into the raw water storage tank 1, which is convenient for recycling. When the water quality is polluted, the electronic valve 14 presses the valve core 15 to the middle and lower section so that the water flows through the sewage pipeline 17. When the pure water machine 5 is deactivated, The valve core 15 is pressed into the parking slot 20 at the bottom through the electronic valve 14. At this time, all three passages are closed. The amount of raw water entering the raw water inlet 3 is controlled by the float valve 2 to prevent overflow. After the qualified ultrapure water enters the ultrapure water tank 11, the water production amount is controlled by the float liquid level switch 12. When the liquid level in the ultrapure water tank 11 is lower than the lower end float, the water mechanism is turned on to produce water. When the water level reaches the upper end float, the water mechanism is stopped. The staff turns on the power switch 18 to control the pure water machine 5 to process the raw water. By turning on the water pump 19, the ultrapure water is output to the electronic four-way press valve 9. The stability of the pure water machine 5 during the chemical industry experiment is improved by the pad 22 made of nitrile rubber.
