[0002] Water quality testing involves monitoring and evaluating various pollutants in water bodies to understand water quality and protect the health of water resources. Before testing water with high levels of impurities, pretreatment is necessary to remove larger impurities; therefore, filtration is required.

[0003] For example, the utility model application with application number 202323184165.2 discloses a water quality testing pretreatment device. Similar water quality testing pretreatment devices currently have the following shortcomings: In the pretreatment process, a simple filter screen is generally used for filtration, which has low filtration efficiency and is relatively troublesome to remove impurities.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a pretreatment device for water quality testing. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for water quality testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for water quality testing, comprising an outer shell, a filter cylinder, and a cleaning assembly. A bottom frame is fixed to the bottom of the outer shell, and a filter cylinder is disposed in the middle of the interior of the outer shell. The outer wall of the filter cylinder has a mesh-like perforated structure. A guide bucket is fixed to the lower side of the filter cylinder, and a water outlet valve pipe is connected to the bottom of the guide bucket. A cleaning assembly is disposed on the outer side of the filter cylinder, and the cleaning assembly includes a cleaning brush, a connecting rod, and a scraper. A connecting rod is fixed to one side of the cleaning brush, and the cleaning brush has an "L"-shaped structure. A scraper is connected to one side of the connecting rod, and the outer side of the scraper is in contact with the inner wall of the outer shell.

[0007] Furthermore, the vertical center line of the outer shell coincides with the vertical center line of the filter cartridge, and two water inlet pipes are connected to the upper side of the outer shell.

[0008] Furthermore, a circular slot corresponding to the filter cylinder is provided in the middle of the bottom frame, and the bottom frame and the filter cylinder are fixedly connected.

[0009] Furthermore, two cleaning brushes are symmetrically arranged about the vertical center line of the filter cylinder, and the inner side of the cleaning brush is in contact with the outer side of the filter cylinder.

[0010] Furthermore, the cleaning assembly also includes a push plate, which is connected to the lower side of the cleaning brush and scraper, and the push plate has an inclined structure.

[0013] Furthermore, two support frames are symmetrically installed on the outer sides of the outer shell, and the outer shell and the support frames are fixedly connected.

[0014] This utility model provides a pretreatment device for water quality testing, which has the following beneficial effects:

[0015] This utility model is equipped with a cleaning component. The drive motor and rotating shaft facilitate the rotation of the cleaning brush, which can clean the outer surface of the filter cartridge and prevent clogging. At the same time, the cleaning brush can drive the scraper to rotate synchronously through the connecting rod, so that the scraper can clean the inner wall of the outer shell and prevent scale buildup on the inner wall of the outer shell after long-term use.

The water to be treated is easily sent into the interior of the outer shell 1 through the water inlet pipe 8. The filter cylinder 2 can filter the water inside the outer shell 1. Compared with the horizontal ordinary filter screen, the filter cylinder 2 has a larger filtration surface and faster filtration efficiency. It can filter both the top and the sides. The filtered water can be discharged through the guide bucket 3 and the outlet valve pipe 4, which is convenient for subsequent water quality testing.

[0023] like Figures 1-2As shown, a cleaning assembly 5 is provided on the outside of the filter cartridge 2. The cleaning assembly 5 includes a cleaning brush 501, a connecting rod 502, and a scraper 503. The connecting rod 502 is fixed to one side of the cleaning brush 501, and the cleaning brush 501 has an "L"-shaped structure. The scraper 503 is connected to one side of the connecting rod 502, and the outer side of the scraper 503 is in contact with the inner wall of the outer casing 1. Two cleaning brushes 501 are symmetrically arranged about the vertical center line of the filter cartridge 2, and the inner side of the cleaning brush 501 is in contact with the outer side of the filter cartridge 2. The cleaning assembly 5 also includes a push plate 504. The push plate 504 is connected to the lower side of the cleaning brush 501 and the scraper 503, and the push plate 504 has an inclined structure. The lower side of the push plate 504 is in contact with the upper side of the bottom frame 9, and two drain valve pipes 10 are connected to the lower two sides of the bottom frame 9. The upper ends of the two cleaning brushes 501 are connected to a rotating shaft 6, and a drive motor 7 is installed on the upper side of the rotating shaft 6.
