Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a sample mixing mechanism for water quality testing. Background Technology

[0002] The sample mixing mechanism for water quality testing is a key component in the water quality testing process. Its core function is to efficiently and accurately mix various types of water samples. On the one hand, it uses mechanical power to promote the uniform distribution of components within the water sample, eliminating local concentration differences and ensuring that the sample is highly representative. On the other hand, when adding test reagents, it accelerates the chemical reaction between the two, not only shortening the testing time but also ensuring testing accuracy. Whether dealing with surface water, sewage, or industrial wastewater, it lays a solid foundation for multiple accurate water quality tests, allowing the test results to truly and reliably reflect the water quality status.

[0003] For example, the utility model patent with publication number CN220650246U discloses a water sample mixing device for water quality testing, which includes a mixing tank, a stirring and mixing mechanism and a rotary sample injection mechanism, both of which are located on the mixing tank.

[0004] When conducting water quality tests inside test tubes, the test tubes usually have a small diameter, making it difficult for conventional stirring equipment to fit. Often, it is necessary to customize a stirring device specifically designed for small test tube sizes to mix the water sample and the test reagents. In actual operation, due to the limitations of the size of the stirring components and the operating space, it is still impossible to effectively reach the corners at the bottom of the test tube. As a result, these hard-to-reach corners cannot be fully stirred, which negatively affects the overall mixing uniformity. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional stirring equipment in the prior art is difficult to mix the liquid to be tested inside small test tubes. It requires the customization of a stirring device that is specially adapted to the size of small test tubes to achieve the mixing of water samples and test reagents. Furthermore, in actual operation, due to the limitations of the size of the stirring components and the operating space, it is still impossible to effectively reach the corners at the bottom of the test tube, resulting in these hard-to-reach corners not being fully stirred. Therefore, this invention proposes a sample mixing mechanism for water quality testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Preferably, the plurality of sub-slot liquid inlets include a guide pipe, an electrically controlled valve, and a liquid storage tank to be tested. The input end of the guide pipe is fixedly connected to one end of the electrically controlled valve, and the other end of the electrically controlled valve is fixedly connected to the output end of the liquid storage tank to be tested.

[0012] Preferably, a sealing ring is fixedly connected to the outer side of the sealing plug, and several handles are fixedly connected to one side of the detachable mixing tank in a centrally symmetrical manner.

[0013] Preferably, a pressure strip is provided above the sealing strip, and positioning frames are fixedly connected to both ends of the pressure strip. A positioning bolt is threaded to one end of the positioning frame, and a positioning bolt is threaded to one end of the positioning bolt on the mixing table.

[0014] Preferably, the mixing chamber is internally fixedly connected with several positioning protrusions, and the several mixing sub-slots are divided into several groups at equal intervals, with the positioning protrusions and the several groups of mixing sub-slots being spaced apart.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, ultrasonic waves are transmitted sequentially through the mixing chamber and the detachable mixing tank to the interior of the liquid to be tested and the reaction substance to be tested. With the help of the unique action mechanism of ultrasonic waves in the liquid medium, the liquid and the reaction substance to be tested can be mixed quickly and efficiently. The mixing effect shows a high degree of uniformity, effectively avoiding the drawbacks of uneven local mixing that are easy to occur due to conventional stirring methods.

[0017] 2.
