AI Technical Summary

Technical Problem

Traditional stratified sampling devices for wastewater treatment ponds agitate the water during the sinking process, causing wastewater from different layers to mix, making precise isolation impossible. Furthermore, they cannot adapt to wastewater ponds of different depths, resulting in distorted test data and increased equipment procurement costs.

Method used

A layered sampling device consisting of a main component and extension components was designed. Through the mechanical connection of the clamp and the slot, the sampling port is kept sealed during the sinking process. After reaching the target depth, it is rotated to open for sampling, thus avoiding mixing of different water layers. By adding extension components section by section, it can adapt to different depths and form independent sampling units.

Benefits of technology

It ensures that wastewater samples are not contaminated by other water layers during the lifting process, thus guaranteeing data accuracy and significantly reducing the cost of repeated equipment purchases. It is suitable for industrial scenarios with large depth fluctuations or requiring multi-point comparative monitoring.

Abstract

The utility model discloses a stratified sampling device of a wastewater treatment tank, which is applied to the technical field of industrial wastewater sampling and comprises a main part, a first rotary drum is rotatably sleeved in the main part, an expansion part is arranged at the bottom of the main part, and a second rotary drum is rotatably sleeved in the expansion part. Clamping grooves are formed in the centers of the bottoms of the first rotating cylinder and the second rotating cylinder, a clamping rod is bolted to the center of the top of the second rotating cylinder, the surface of the clamping rod is connected with the interior of the clamping groove in the top in a sleeved mode, a sampling groove is formed in the second rotating cylinder, and a second sampling opening is formed in the left side of the top of the sampling groove. A first sampling opening is formed in the middle of the right side of the expansion piece, and expansion mechanisms are arranged at the tops of the two sides of the expansion piece; the closed state is kept when the device sinks, so that the accuracy of sampling data is ensured, and the device is particularly suitable for industrial wastewater scenes needing strict layered monitoring; and wastewater pool structures with different depths can be accurately matched, the shallow sampling requirement is met, the deep pool working condition can be coped with by overlapping the expansion pieces, and the adaptability of the device is greatly improved.
