Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sampling device for sewage treatment. Background Technique

[0002] Sewage treatment is mainly a process for treating sewage, which is beneficial to the work of removing impurities in the sewage, facilitating the purification of the sewage, and facilitating the reuse of water resources. A sampling device is required in the process of sewage treatment.

[0003] The existing Chinese utility model patent with the reference publication number: CN212988885U discloses a sampling device for sewage treatment. The following scheme is now proposed, including a sampling cylinder. The bottom end of the sampling cylinder is fixedly installed with a water outlet pipe, and the top end of the sampling cylinder is threadedly installed with a cover plate, and a through hole is provided on the cover plate. A bottom block is installed inside the sampling cylinder, and a first water inlet hole is provided on the bottom block, and a positioning groove is provided on the center top surface of the bottom block. The utility model can drive the circular plate to rotate through the positioning block by pulling and then rotating the connecting shaft, which is convenient for the second water inlet hole on the circular plate to be aligned with or separated from the first water inlet hole and the third water inlet hole, so as to facilitate the work of water inlet and sealing, and facilitate the subsequent preservation of the collected samples. During the sealing process, the sampling device can be directly washed.

[0004] The existing sampling device generally pumps water into the lumen through a silica gel plug. Since the sewage may carry particulate matter, when the particulate matter adheres to the inner wall of the lumen, it will enter between the silica gel plug and the lumen, causing wear of the lumen. And the sewage may corrode the inner wall of the lumen of the sampling device, affecting the service life of the sampling device. At the same time, the sewage may carry various solid impurities, and the impurities may enter the sampling device during the sampling process. Content of the Utility Model

[0015] Compared with the prior art, the utility model provides a sampling device for sewage treatment, which has the following beneficial effects:

[0016] 1. Through the setting of the silica gel tube in the utility model, the silica gel tube is connected to the connecting block at the upper end through a clamp and to the limiting block at the lower end. The inner wall of the limiting block is provided with a threaded structure, and the limiting block is movably connected to the connecting ring through the threaded structure. The upper end of the connecting block is fixedly connected to the lower end of the transmission rod.

At the same time, the lower half of the water inlet pipe is in a conical structure with a small opening at the bottom end, which can prevent the sampling device from sucking large impurities.

[0027] The housing 1 is a tubular structure. The surface of the limiting ring 11 is provided with an opening structure that is annularly distributed at equal angles with the center of the limiting ring 11 as the reference. The connecting pipe 13 is movably connected to the housing 1 through a threaded structure. The filter screen 15 is a cylindrical structure.

The inner wall of the water inlet pipe 16 is provided with a threaded structure, and the water inlet pipe 16 is movably connected to the filtering pipe 14 through the threaded structure. The upper half of the water inlet pipe 16 is a cylindrical structure, and the lower half of the water inlet pipe 16 is a conical structure.

[0028] Specifically, the outer shell 1 can protect the internal silicone tube 23. The limiting ring 11 can limit the position of the transmission rod 2. The connecting ring 12 can facilitate the connection between the limiting block 25 and the outer shell 1. The connecting pipe 13 can limit the position of the filter pipe 14. The filter pipe 14 can limit the water flow through the filter screen 15. The filter screen 15 can filter solids in the water flow. The water inlet pipe 16 can facilitate the sewage to enter the inside of the silicone tube 23.

[0029] The transmission rod 2 is inserted and installed through the center of the limiting ring 11. A handle 21 is fixedly installed above the transmission rod 2. A connecting block 22 is fixedly installed below the transmission rod 2. A silicone tube 23 is fitted and installed below the connecting block 22. A clamp 24 is inserted and installed on the outer side of the silicone tube 23. A limiting block 25 is inserted and installed below the silicone tube 23.

[0030] A sliding connection is formed between the transmission rod 2 and the limiting ring 11. The connecting block 22 is in a disc shape. A concave structure for fitting with the clamp 24 is provided on the outer sides of the connecting block 22 and the limiting block 25. The clamp 24 is symmetrically installed above and below the silicone tube 23 with the center of the silicone tube 23 as the reference. The silicone tube 23 is movably connected to the connecting block 22 at the upper end and the limiting block 25 at the lower end through the clamp 24. A threaded structure is provided on the inner wall of the limiting block 25. An active connection is formed between the limiting block 25 and the connecting ring 12 through the threaded structure.

[0031] Specifically, the transmission rod 2 can facilitate the adjustment of the position of the connecting block 22. The handle 21 can facilitate the user to adjust the position of the transmission rod 2. The connecting block 22 can facilitate the limitation of the upper position of the silicone tube 23. The thickness of the silicone tube 23 is two millimeters and its internal volume can be changed by deformation. The clamp 24 can facilitate the connection between the silicone tube 23 and the connecting block 22 and the limiting block 25. The limiting block 25 can limit the lower position of the silicone tube 23.

[0032] During use, the silicone tube 23 is connected to the connecting block 22 through the upper end of the clamp 24 and to the limiting block 25 through the lower end. The inner wall of the limiting block 25 is provided with a threaded structure, and the limiting block 25 is movably connected to the connecting ring 12 through the threaded structure. The upper end of the connecting block 22 is fixedly connected to the lower end of the transmission rod 2.

The filter screen 15 is inserted and installed at the bottom end of the filter tube 14. Since the upper half of the water inlet pipe 16 is a cylindrical structure and the water inlet pipe 16 is movably connected to the filter tube 14 through a threaded structure, the water inlet pipe 16 can limit the filter screen 15 at the bottom end of the filter tube 14. This method can allow sewage to pass through the filter screen 15, so as to facilitate the filter screen 15 to capture solid particles in the sewage and prevent solid particles from entering the lumen. At the same time, the lower half of the water inlet pipe 16 is a conical structure with a small opening at the bottom end, which can prevent the sampling device from sucking large impurities.
