Description

Technical Field

[0001] The utility model relates to the technical field of sewage collection, in particular to a sewage collector for uniform sampling. Background Art

[0002] Sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment. Industrial sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended solid particles of different sizes; colloidal and gelatinous diffusions; pure solutions. Sewage seriously affects people's quality of life and threatens people's health. The reduction of scarce water resources has attracted more and more attention to sewage treatment. The basis of sewage treatment is to sample sewage and then formulate corresponding sewage treatment plans based on experimental data.

[0003] For example, the utility model with application number CN202121984440.7 discloses a sampler for collecting sewage, which relates to the technical field of samplers. The utility model has a filter cartridge slidably installed inside the sampler body, which can filter larger waste materials during the sampling process to prevent larger waste materials from entering and causing blockage of the sampler body. The sampling is more convenient and suitable for promotion and use. However, existing sewage collectors usually collect sewage from a single location during collection. After stratification, the sewage collected at a single point is prone to being uneven, resulting in deviations in the test results.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sewage collector with uniform sampling is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a sewage collector with uniform sampling to solve the problems raised in the above background technology.

[0013] Further, the auxiliary component further includes a sealing plate and a filter plate. The end of the connecting frame is connected to the sealing plate, and the filter plate is arranged below the sealing plate.

[0014] The utility model provides a sewage sampler for uniform sampling, which has the following beneficial effects:

[0015] 1. In the utility model, a plurality of collection tubes are assembled in the vertical direction through a connecting ring, so that the collection tubes simultaneously collect sewage at different height positions in the sewage.

Specific embodiments

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, a sewage sampler with uniform sampling includes a fixed block 1 and a connecting component 4. A collection tube 2 is arranged inside the fixed block 1. The sewage mixed by multiple collection tubes 2 can make the result more accurate during subsequent sewage detection, avoiding the collected samples being unrepresentative due to sewage stratification. Connecting rings 3 are installed at the upper and lower ends of the fixed block 1. The connecting rings 3 assemble multiple groups of collection tubes 2 in the vertical direction, enabling the collection tubes 2 to uniformly collect sewage at different height positions in the sewage at the same time. A waterproof electric push rod 5 is installed at the lower end of the side of the fixed block 1. The waterproof electric push rod 5 controls the pulling and pushing of the sampling piston 9 in the collection tube 2 to quickly collect sewage. The output end of the waterproof electric push rod 5 is installed with a control board 6. The surface of the control board 6 is installed with an installation frame 7, and an installation disc 8 is arranged inside the installation frame 7. The installation disc 8 is slidably engaged in the installation frame 7 for the installation of the sampling piston 9, enabling the waterproof electric push rod 5 to better control the sampling piston 9. The shape of the installation frame 7 is a U-shaped, and the installation frame 7 and the installation disc 8 are connected by sliding engagement. A sampling piston 9 is arranged inside the collection tube 2.

[0023] As Figure 2 shown, the connecting component 4 for multi-point uniform sampling of water quality is arranged inside the connecting ring 3. The connecting component 4 includes a lower joint 401, a telescopic rod 402, a limit screw 403, and an upper joint 404. The end of the lower joint 401 is installed with a telescopic rod 402. The telescopic rod 402 is used for connecting the fixed block 1 through the lower joint 401 and the upper joint 404, with simple operation and easy disassembly. A limit screw 403 is arranged on the outer side of the telescopic rod 402. The limit screw 403 limits the length of the telescopic rod 402 by rotational extrusion. The end of the limit screw 403 is installed with an upper joint 404.

[0024] As Figure 3As shown, the left end of the collection pipe 2 is connected with a collection port 10, and a side groove 11 is provided on the outer surface of the collection port 10. The side groove 11 allows the moving rod 1201 to move within the limit position therein, and an auxiliary component 12 for assisting in collecting sewage is arranged inside the side groove 11. The auxiliary component 12 includes a moving rod 1201 and a connecting frame 1202, and the connecting frame 1202 is installed on the side of the moving rod 1201. The moving rod 1201 is respectively installed with a sealing plate 1203 and a filter plate 1204 through the connecting frame 1202. The auxiliary component 12 also includes a sealing plate 1203 and a filter plate 1204. The end of the connecting frame 1202 is connected with a sealing plate 1203. The sealing plate 1203 can temporarily block the collection port 10 to avoid collecting unnecessary liquids, and a filter plate 1204 is arranged below the sealing plate 1203. The filter plate 1204 can filter the sewage during collection to avoid the collection of sewage affected by domestic garbage.

[0025] In summary, the uniformly sampled sewage collector is first based on Figure 1-Figure 3 According to the structure shown in the figure, before collecting, the staff selects a suitable number of collection tubes 2 according to the depth and stratification of the sewage, and uses the telescopic rod 402 to assemble and connect multiple groups of collection tubes 2 in sequence in the vertical direction. After pulling out the telescopic rod 402, the limiting screw 403 is rotated so that its end can squeeze and limit the inner tube. The assembled collector is placed in the sewage for collection through the control rod connected to the top fixed block 1. When launching the sewage, the sealing plate 1203 can be slid down in the side groove 11 to the end of the collection port 10 for temporary blocking to avoid collecting unnecessary liquid. When collecting, the moving rod 1201 is pulled by stretching to make The sealing plate 1203 moves up, and the collection port 10 is exposed. At the same time, the waterproof electric push rod 5 is opened to push the control panel 6 to move, driving the sampling piston 9 to be withdrawn in the collection tube 2 to complete the collection of sewage. At this time, multiple groups of collection tubes 2 can be used to evenly collect sewage at different heights in the sewage. The sewage mixed by multiple collection tubes 2 can have more accurate results in the subsequent sewage detection, avoiding the unrepresentativeness of the collected samples due to sewage stratification. During collection, the filter plate 1204 can also be pulled onto the collection port 10. The filter plate 1204 filters the sewage during collection to avoid the influence of domestic garbage on the collection of sewage.
