Description

Technical Field

[0001] The utility model relates to a continuous microorganism-marking self-cleaning system, belonging to the technical field of microorganism-marking cleaning. Background Art

[0002] As urban and rural residents' awareness of drinking water health continues to improve, water purifiers have become an indispensable healthy drinking water product for both urban and rural residents. Microbial removal rate is one of the main indicators for evaluating the water purification characteristics of water purification equipment. In the functional evaluation tests of water treatment equipment such as water purification equipment or filters, microbial spike tests for infectious pathogens such as Escherichia coli, Giardia, Cryptosporidium, and Campylobacter are usually conducted. The microbial spike test involves first preparing a microbial spike solution of a certain concentration, then passing a certain volume of the spike solution through the water treatment equipment, and then testing the concentration of microorganisms in the water after treatment by the water treatment equipment to test the water treatment equipment's ability to remove microorganisms from the water.

[0003] At present, most microbial spiking is done by preparing a solution in a barrel. This mode requires many manual water preparation times, and it is difficult to achieve continuous spiking throughout the entire process. After microbial spiking, there will be a large number of bacteria in the pipelines and equipment. Without perfect disinfection measures, it is easy to cause explosive reproduction of microorganisms, affecting subsequent testing and safety. At the same time, microorganisms are easily affected by temperature, which causes changes in the reproduction rate and large changes in the bacterial concentration of the spiked solution. To this end, the present application provides a continuous microbial spiking self-cleaning system, which can achieve self-cleaning while realizing continuous spiking, and can control the reproduction of microorganisms, thereby improving the accuracy of detection and reducing or avoiding the impact on subsequent tests. Utility Model Content

[0004] The utility model provides a continuous microbial labeling and self-cleaning system, which can continuously add labels and self-clean, and can control the reproduction of microorganisms, thereby improving the accuracy of detection, reducing or avoiding the impact on subsequent tests, and has a simple structure and is easy to control.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A continuous microbial spiked self-cleaning system comprises: a microbial concentrate barrel, a first circulation pump, a constant temperature refrigerator, a UV lamp, a bacterial suspension filler, a first pipeline, a purified water source, a water purifier to be tested, a first solenoid valve, a proportional pump, a mixer, a second solenoid valve, a second pipeline, an ozone generator, a third pipeline, a third solenoid valve, a second circulation pump, a fourth pipeline, a drain valve, and a wastewater treatment device;

[0007] The microbial concentrate barrel and the first circulation pump are both located in a constant temperature refrigerator. The water inlet of the first circulation pump is connected to the bottom of the side wall of the microbial concentrate barrel through a pipeline, and the water outlet of the first circulation pump is connected to the top of the side wall of the microbial concentrate barrel through a pipeline. The UV lamp is installed on the top of the microbial concentrate barrel. The bottom of the bacterial suspension filler is the discharge end. The bacterial suspension filler is detachably mounted on the top of the microbial concentrate barrel, and the discharge end of the bacterial suspension filler can pass through the top of the microbial concentrate barrel and extend into the microbial concentrate barrel.

[0008] One end of the first pipe is connected to the purified water source, and the other end is connected to the water purifier to be tested;

[0009] The first solenoid valve, the proportional pump, the mixer, and the second solenoid valve are sequentially arranged on the first pipeline, wherein the first solenoid valve is adjacent to the clean water source, and the second solenoid valve is adjacent to the water purifier to be tested, that is, the first solenoid valve, the proportional pump, the mixer, and the second solenoid valve are sequentially arranged in the direction from the clean water source to the water purifier to be tested;

[0010] One end of the second pipeline is connected to the proportional pump, and the other end is connected to the bottom of the microbial concentrate barrel; the ozone generator is installed on the second pipeline;

[0011] One end of the third pipeline is connected to the first pipeline between the first solenoid valve and the proportional pump, and the other end is connected to the first pipeline between the mixer and the second solenoid valve; the third solenoid valve and the second circulating pump are sequentially arranged on the third pipeline, and the third solenoid valve is closer to the first solenoid valve than the second circulating pump;

[0012] One end of the fourth pipeline is communicated with the first pipeline between the mixer and the second electromagnetic valve, and the other end leads to the wastewater treatment device; the drain valve is arranged on the fourth pipeline.

[0013] The clean water source is pure water that meets the spiked requirements.

[0014] In this application, connectivity means connection and communication.

[0015] To improve test accuracy, the continuous microbial spiked self-cleaning system further includes a fourth solenoid valve. The third solenoid valve, the second circulation pump, and the fourth solenoid valve are sequentially located on the third pipeline. This means that solenoid valves are located on both sides of the second circulation pump to further ensure control and testing accuracy.

[0016] When the above system is used, the following steps are included:

[0017] Preparation: First, use the strain to artificially cultivate a bacterial suspension, inject the bacterial suspension into the bacterial suspension injector, and then flexibly install the bacterial suspension injector on the top of the microbial concentrate barrel. According to the test requirements, add the required amount of bacterial suspension and purified water into the microbial concentrate barrel (the microbial concentrate barrel is provided with a purified water injection port). Start the first circulation pump to mix the bacterial suspension and purified water evenly to obtain the microbial concentrate. The temperature in the constant temperature refrigerator is maintained at 4°C to prevent or reduce bacterial growth and cause an explosive increase in the bacterial concentration of the solution.

[0018] Spiking: Open the first solenoid valve, proportional pump and second solenoid valve, and close the other solenoid valves. The proportional pump extracts pure water and microbial concentrate in proportion. After mixing in the mixer, the water flows through the second solenoid valve and enters the water purifier to be tested, thus realizing continuous microbial spike testing.

[0019] Disinfection: After the microbial spike test is completed, turn on the UV lamp in the microbial concentrate barrel, close the first and second solenoid valves, open the third and fourth solenoid valves and the drain valve, start the ozone generator and the second circulation pump, and extract the solution in the microbial concentrate barrel. The ozone generator will generate ozone that enters the water body and circulates through the circulation pump for sterilization to ensure that the bacteria inside the system are clean.

[0020] The ozone generator is not turned on during the spike test of the water purifier to be tested, and only serves as a passage; it is only turned on during disinfection and cleaning.

[0021] In order to facilitate observation, the bacterial suspension filler is made of transparent material and is provided with a volume scale.

[0022] For ease of operation, the bacterial suspension injector uses a syringe.

[0023] To facilitate control, the continuous microbial spiked self-cleaning system further includes a filler mounting device comprising a base, a micro-cylinder, and a connecting rod. The microbial concentrate barrel is provided with a filling port, and the micro-cylinder is mounted on the outside of the top of the microbial concentrate barrel via the base. An elastic clamp is provided on the sidewall of the base, and a syringe is removably connected to the elastic clamp. The discharge end of the syringe faces and extends into the filling port. The connecting rod is arranged horizontally, with one end connected to the top of the micro-cylinder and the other end located directly above the top of the syringe. This allows the micro-cylinder to extend downward, moving the connecting rod horizontally downward, thereby squeezing the syringe, allowing the bacterial suspension in the syringe to be injected into the microbial concentrate barrel.

[0024] To improve feeding accuracy, a circular groove is located at the bottom of the other end of the connecting rod. The inner diameter of the groove is larger than the diameter of the top of the syringe piston rod and the groove is located directly above the top of the syringe piston rod. When the syringe is squeezed, the top of the piston rod always stays in the circular groove, ensuring accurate and safe feeding.

[0025] As a specific implementation scheme, the first pipeline includes a first pipeline A and a first pipeline B. The proportional pump is provided with a first feed port, a second feed port, and a discharge port. One end of the first pipeline A is connected to the purified water source, and the other end is connected to the first feed port on the proportional pump. One end of the first pipeline B is connected to the discharge port on the proportional pump, and the other end is connected to the water purifier to be tested.

[0026] The first solenoid valve is arranged on the first pipeline A, the mixer and the second solenoid valve are arranged on the first pipeline B; one end of the second pipeline is connected to the second feed port of the proportional pump, and the other end leads to the bottom of the microbial concentrate barrel.

[0027] To facilitate the configuration of the microbial concentrate, the continuous microbial spiked self-cleaning system further includes a fifth pipeline, one end of which is connected to the clean water source and the other end is connected to the microbial concentrate barrel. A fifth solenoid valve is provided on the fifth pipeline.

[0028] The above drain valve is a small hole drain valve. For example, the hydraulic small hole float valve KFQ-01T, brand: Kaixiang.

[0029] To facilitate assembly, the first pipeline and the third pipeline are connected through a tee; the first pipeline and the fourth pipeline are connected through a tee.

[0030] The above-mentioned continuous microbial spiked self-cleaning system includes a test route and a cleaning route; the test route includes: from the clean water source and the microbial concentrate barrel to the proportional pump respectively, and then from the proportional pump to the mixer and the second solenoid valve in sequence, and then enters the water purifier to be tested; the cleaning route includes the following connected in sequence: the microbial concentrate barrel, the ozone generator, the proportional pump, the third solenoid valve, the second circulation pump, the fourth solenoid valve and the drain valve.

[0031] This application combines the existing mature control system and control method to achieve automatic control of the system. This application does not improve the control method, so it will not be repeated.

[0032] The technologies not mentioned in this utility model are all referred to the existing technology.

[0033] The utility model discloses a continuous microbial spiked self-cleaning system, which can spike microbial solutions online and continuously. After the spike is completed, the microorganisms in the system can be disinfected and cleaned, reducing or avoiding the impact on subsequent tests. At the same time, the reproduction of microorganisms can be controlled, preventing or reducing the explosive increase in the bacterial concentration of the solution caused by bacterial growth, thereby improving the accuracy of detection. The structure is simple and easy to control. BRIEF DESCRIPTION OF THE DRAWINGS
