[0002] In the field of environmental monitoring and water pollution research, obtaining representative filtered water samples on-site is a key prerequisite for accurate analysis. As a core sample pretreatment device, the development of vacuum filtration devices has evolved from initially relying on bulky glassware in the laboratory to gradually developing into portable, specialized on-site equipment. These devices are widely used for rapid sampling and filtration in complex on-site environments such as sewage treatment plant outlets, river and lake sections, and industrial wastewater. The aim is to efficiently retain suspended solids, microorganisms, and other solids in water samples on the filter membrane for subsequent laboratory analysis and testing, thereby providing direct evidence for environmental management and scientific research decision-making.

[0003] Traditional filtration devices have a fixed structural design, and the process of disassembling and assembling filter elements is cumbersome. It often requires tools and is difficult to completely separate the filter elements. This not only makes it inconvenient and inefficient to clean and maintain the filter elements, but also causes sample residual contamination during continuous testing because the filter elements cannot be replaced in time. Ultimately, this affects the accuracy of monitoring data and the overall work progress. Therefore, a detachable and cleanable wastewater testing on-site filtration device has emerged.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-5 This embodiment of the present invention provides a detachable and cleanable wastewater testing on-site filtration device, comprising: The sample bottle 101 is connected to the end of the sample bottle 101 by a first connector 102 threadedly, a water pump 103 fixedly installed on the surface of the first connector 102, an inlet pipe 104 fixedly connected to the inlet of the water pump 103, an installation assembly 105 sleeved on the surface of the inlet pipe 104, a quick-release assembly 106 slidably connected to the inner wall of the installation assembly 105, and a limiting assembly 107 provided in the inner cavity of the installation assembly 105. The mounting assembly 105 includes a water outlet plate 105a sleeved on the surface of the water inlet pipe 104, a protective cover 105b fixedly installed at the bottom of the water outlet plate 105a, a sealing strip 105c fitted into the side wall of the protective cover 105b, and a water inlet hole 105d opened on the surface of the protective cover 105b.

[0019] Specifically, the first connector 102 is fixedly installed at the outlet of the water pump 103, and the quick-release assembly 106 and the limiting assembly 107 of the outlet plate 105a provide installation space.

[0020] Furthermore, the quick-release assembly 106 includes a side pull plate 106a that is snapped onto the side wall of the protective cover 105b, a handle 106b that is fixedly installed on the surface of the side pull plate 106a, a mounting plate 106c that is fixedly installed on the end of the side pull plate 106a, a shaft block 106d that is disposed on the surface of the mounting plate 106c, a roller 106e that is rotatably connected to the shaft center of the shaft block 106d, a second connector 106f that is fixedly installed on the bottom of the mounting plate 106c, and a filter element 106g that is threadedly connected to the inner wall of the second connector 106f.

[0021] The bottom of the water outlet plate 105a is provided with a guide rail adapted to the roller 106e. The roller 106e is slidably connected to the bottom of the water outlet plate 105a. The roller 106e slides with the guide rail at the bottom of the water outlet plate 105a through the shaft block 106d and the roller 106e to ensure smooth movement. The second connector 106f has a replaceable filter element 106g connected inside by a thread.

[0022] Preferably, the limiting assembly 107 includes a limiting hole 107a formed on the surface of the mounting plate 106c, a mounting groove 107b formed on the surface of the water outlet plate 105a, a limiting rod 107c inserted into the inner cavity of the mounting groove 107b, a collar 107d sleeved on the surface of the limiting rod 107c, a spring 107e sleeved on the surface of the limiting rod 107c, and a pull buckle 107f fixedly installed at the end of the limiting rod 107c.

[0023] It should be noted that the spring 107e is located in the inner cavity of the mounting groove 107b. Under the preload of the spring 107e, the limiting rod 107c can be inserted into the limiting hole to lock the filter element 106g in the working position. The locking can be released by pulling the buckle 107f.

[0024] In use, the quick-release assembly 106 containing the filter element 106g is pushed into the protective cover 105b of the mounting assembly 105. The roller 106e slides along the guide rail. When it moves to the working position, the limiting rod 107c automatically springs into the limiting hole 107a on the mounting plate 106c under the action of the spring 107e. The sealing strip 105c inside the protective cover 105b ensures a seal with the contact surface of the quick-release assembly 106 to prevent water leakage. The water pump 103 is started, and the water sample is drawn from the sample bottle 101. The water sample is delivered through the inlet pipe 104 and enters the inner cavity of the protective cover 105b through the inlet hole 105d. The water sample passes through the filter element 106g, where suspended solids are trapped on the surface of the filter element 106g. The filtered clean water is discharged through the second connector 106f, completing the filtration process. Pulling the buckle 107f on the limiting rod 107c releases it from the limiting hole 107a, thus unlocking it. The entire quick-release assembly 106 can be pulled out of the protective cover 105b through the handle 106b.

[0025] In summary, the installation component 105 provides installation space for the quick-release component 106 and the limiting component 107. The combined use of the installation component 105 and the quick-release component 106 enables the rapid replacement of the filter element 106g, facilitating cleaning. The combined use of the quick-release component 106 and the limiting component 107 enables the rapid disassembly and installation of the filter element 106g, simplifying the process of replacing the filter element 106g and cleaning the device. The device is easy and efficient to operate, effectively solving the problems of traditional filtration devices where the cumbersome replacement of the filter element 106g leads to untimely cleaning of the filter element 106g, affecting the monitoring progress and effect.
