Description

Technical Field

[0001] This utility model relates to the field of water quality testing, and more specifically, it relates to a water quality testing container with a high replacement rate. Background Technology

[0002] Water quality testing is the process of determining the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate the water quality status. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater.

[0003] For example, the water quality monitoring container disclosed in authorization announcement number CN210410782U stirs and filters the aqueous solution to be tested, making it convenient for subsequent testing.

[0004] However, in practice, the water flow in the aforementioned methods is often insufficient, resulting in "dead water zones." This means the water sample contacted by the electrodes cannot accurately represent the overall water sample being tested, ultimately affecting the reliability of the test results and making it impossible to accurately obtain parameters such as conductivity and pH. Furthermore, after prolonged use, impurities and scale can easily accumulate inside the flow cup or flow tank. Due to its relatively complex internal structure, it is difficult to thoroughly clean narrow gaps and corners. This not only affects the accuracy of subsequent water sample testing but may also breed bacteria and other microorganisms, further interfering with the detection process, and is also detrimental to the long-term stable operation and maintenance of the equipment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-displacement-rate water quality testing container that solves the problems of complex electrode installation, insufficient detection representativeness, low replacement rate and inconvenient maintenance, reduces maintenance costs and improves detection efficiency.

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

[0007] A high-displacement-rate water quality testing container includes an outer shell and a cover connected to the outer shell. A mounting bracket is provided on one side wall of the outer shell, and a receiving cavity is formed inside the outer shell. Two water outlet holes communicating with the receiving cavity are formed on the side wall of the outer shell, and each of the two water outlet holes is provided with a water outlet pipe for connection to a water pipe.

[0008] The lower end face of the outer casing has a water inlet hole communicating with the cavity, and the water inlet hole is equipped with a water inlet pipe connected to the water pump.

[0009] The upper surface of the outer shell has an opening, and the opening end face is provided with an extension plate for connecting with the cover. The width of the extension plate is smaller than the width of the outer shell. The cover has two docking holes for installing sensors. Both the outer shell and the cover are made of nylon polyamide PA12 material combined with 3D printing sintering process.

[0010] The present invention is further configured such that two mounting slots are provided on one side of the mounting bracket.

[0011] The present invention is further configured such that the cross-section of the outer shell is a right trapezoid.

[0012] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0013] By combining the lid and outer shell using nylon polyamide PA12 material through 3D printing and sintering, this process ensures both structural strength and adaptability to complex water conditions (strong acids and alkalis). A mounting bracket on the back of the container facilitates installation in various locations. An inlet and two outlets allow for easy water intake and discharge. The lid has two sensor connection holes, compatible with 90% of commercially available pH and conductivity electrodes. The container's design, wider at the top and narrower at the bottom, yielded a displacement rate of 183% per minute at a flow rate of 10 cm / s. This design provides a third installation option for containers unsuitable for conventional methods. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Working principle: First, install the outer shell 1 on the corresponding monitoring station through the mounting bracket 3. Then, connect the water inlet pipe 7 to the water pump and connect the two water outlet pipes 5 to the water outlet pipe. Then, install the sensor in the docking hole 9 and cover the outer shell 1 with the cover 2 so that the extension plate 8 is placed inside the cover 2.

[0019] During operation, water enters the housing 1 through the inlet pipe 7 and is detected by the sensor placed in the receiving cavity. Finally, the water flows out through the outlet pipe. When it is necessary to clean the inside of the housing, simply remove the cover 2. Since the sensor is connected to the docking hole 9, it will not affect the cleaning process.

[0020] like Figure 1 As shown,

[0021] It includes a housing 1 and a cover 2 connected to the housing 1. The housing 1 has a right trapezoidal cross section, and its various sizes are designed to facilitate the detection of water placed in the containment cavity by the sensor.

[0022] The outer casing 1 has a mounting bracket 3 on one side wall. Two mounting slots 10 are opened on one side of the mounting bracket 3. The outer casing 1 is fixed to the corresponding testing station through the mounting slots 10. It is suitable for various installation environments by connecting with screws.

[0023] The outer shell 1 has a receiving cavity, and the side wall of the outer shell 1 has two water outlet holes 4 that communicate with the receiving cavity. Each of the two water storage holes is provided with a water outlet pipe 5 for connecting to a water pipe, and water is discharged through the two water outlet holes 4 on the side of the outer shell 1.

[0024] The lower end face of the outer casing 1 is provided with a water inlet hole 6 that communicates with the cavity, and a water inlet pipe 7 connected to the water pump is provided on the water inlet hole 6.

[0025] The upper surface of the outer shell 1 has an opening, and the opening end face is provided with an extension plate 8 for connecting with the cover 2. The width of the extension plate 8 is smaller than the width of the outer shell 1, which increases the stability of the connection between the cover 2 and the outer shell 1.

[0026] The cover 2 has two docking holes 9 for installing sensors. Both the outer shell 1 and the cover 2 are made of nylon polyamide PA12 material combined with 3D printing sintering process. The 3D printing sintering nylon process can ensure structural strength and adapt to complex water quality.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
