[0002] Wastewater testing is an important means of environmental monitoring. It can promptly detect and assess pollutants in wastewater, ensure the operational effectiveness and treatment capacity of wastewater treatment facilities, thereby protecting water resources and preventing water pollution. Before wastewater testing, wastewater samples need to be obtained and preserved before the testing steps can be carried out.

[0003] Wastewater often contains a large number of large impurities, which are generally not within the scope of wastewater testing. Wastewater testing usually detects the bacterial content and other chemical elements in the water. These large impurities will only interfere with the testing process. Existing wastewater sample storage devices do not have the ability to remove impurities and have relatively limited functions. After the wastewater sample is taken out, it is still necessary to remove impurities from the wastewater, which is very troublesome.

[0004] To address the problem that large impurities can interfere with the testing process, existing wastewater sample storage devices lack the ability to remove impurities and have limited functionality, requiring further impurity removal after the wastewater sample is removed, which is quite troublesome, a storage device is designed to remove large impurities from the wastewater during the closed storage process to overcome the above problems.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 - Figure 8 This utility model provides an embodiment of a wastewater sample storage device, including a storage box 1, an upper cover 4, and a side cooling box 17. The upper cover 4 is provided at the upper end of the storage box 1, and the side cooling box 17 is fixedly connected to one side of the storage box 1. The lower end of the upper cover 4 is provided with a stirring component for stirring and filtering wastewater samples. The side cooling box 17 is provided with a refrigeration component for refrigerating the wastewater samples in the storage box 1. When the storage device is closed, large impurities in the wastewater can be separated and stored at the bottom of the storage box 1. During the process, the refrigeration component is opened to ensure that the wastewater samples can be preserved to the maximum extent. After the storage box 1 is opened, the stirring component will automatically stir the wastewater, making the components in the waste liquid sample more evenly distributed, thus making the detection more accurate.

[0026] Please see Figure 1 - Figure 3In this embodiment, the stirring assembly includes a bearing seat 5, which is fixedly installed at the lower end of the upper cover 4. A twisted rod 6 is rotatably connected to the lower end of the bearing seat 5, and a rotating rod 9 is fixedly connected to the lower end of the twisted rod 6. The lower end of the rotating rod 9 has a groove, and a magnet 10 is fixedly connected to the groove at the lower end of the rotating rod 9. A support frame 7 is fixedly installed on the upper end of the inner wall of the storage box 1, and a retaining ring 8 is fixedly connected to the center of the support frame 7. The retaining ring 8 is adapted to the twisted rod 6 and is used to rotate the twisted rod 6 and the rotating rod 9. A connector 13 is slidably connected in the groove at the lower end. The connector 13 is attracted by a magnet 10. An annular piston 11 is fixedly connected to the lower end of the connector 13. A filter plate 12 is fixedly connected inside the annular piston 11. Grooves are symmetrically arranged at the lower end of the annular piston 11. An iron sheet 24 is fixedly connected inside the groove of the annular piston 11. A base 14 is fixedly connected to the bottom of the storage box 1. A magnet 15 is connected to the upper end of the base 14. The magnet 15 is adapted to the groove of the annular piston 11 and is used to attract the iron sheet 24.

[0027] Please see Figure 3 and Figure 6 In this embodiment, the refrigeration assembly includes a water storage tank 18, a water outlet pipe 19 fixedly connected to one side of the water storage tank 18, a through hole on the surface of the water outlet pipe 19, a rubber plug 20 at the through hole of the water outlet pipe 19, the rubber plug 20 being used to block the water outlet pipe 19, side fixing plates 21 fixedly installed on both sides of the top cover 4, threaded handles 22 threadedly connected to the surface of the side fixing plates 21, an upper cover 23 fixedly connected to the upper end of the side cooling box 17, a threaded hole at the upper end of the upper cover 23, the upper cover 23 being threadedly connected to the threaded handle 22, the threaded handle 22 being used to fix the top cover 4 and to push open the rubber plug 20, side sleeves 2 fixedly installed on both sides of the storage box 1, a sliding rod 3 slidably connected inside the side sleeve 2, a spring 16 inside the side sleeve 2, the spring 16 being used to push the sliding rod 3 upward.

[0028] During use, the wastewater sample is first poured into the storage box 1, then the top cover 4 is pressed down. Next, the threaded handle 22 on the side fixing plate 21 is threaded into the upper threaded hole of the top cover 23, thus fixing the top cover 4. As the top cover 4 descends, the annular piston 11, attracted by magnet 10 to the lower end of the twisted rod 6, descends simultaneously. During this process, the filter plate 12, fixedly connected to the annular piston 11, filters large impurities in the wastewater to the bottom of the storage box 1. When the annular piston 11 moves to the base 14 at the bottom of the storage box 1, magnet 15 at the upper end of the base 14 attracts the iron piece 24 in the groove of the annular piston 11, thereby pulling the connector 13 out of the groove of the rotating rod 9. The annular piston 11, filter plate 12, and base 14 together form a cavity to store large impurities from the wastewater sample. After tightening the threaded handle 22, the threaded handle 22... One end of 2 passes through the upper cover 23 and squeezes down the rubber stopper 20 at the outlet pipe 19, causing water to flow out of the water storage tank 18. The side cooling tank 17 contains ammonium salt fillers such as ammonium sulfate. The water reacts with the fillers in the side cooling tank 17 to achieve a cooling effect. This reaction is a mature existing technology and will not be described in detail here. In this way, the refrigeration is turned on while the wastewater sample is sealed, ensuring that the wastewater sample can be preserved to the maximum extent. When it is necessary to remove the wastewater sample, the threaded handle 22 is removed, and the spring 16 in the side sleeve 2 lifts the slide rod 3 upward, opening the upper cover 4. During this process, the retaining ring 8 on the support frame 7 causes the twist rod 6 to rotate by squeezing the texture of the twist rod 6. During the rotation of the twist rod 6, the rotating rod 9 fixedly connected to the lower end of the twist rod 6 stirs the waste liquid sample, making the components in the waste liquid sample more evenly distributed, which will make the detection more accurate.

[0029] Through the above steps, when the storage device is closed, large impurities in the wastewater can be separated and stored at the bottom of the storage box 1. During the process, the refrigeration component is turned on to ensure that the wastewater sample can be preserved to the maximum extent. After the storage box 1 is opened, the stirring component will automatically stir the wastewater, making the components in the waste liquid sample more evenly distributed, which will make the detection more accurate.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
