Description

Double-layer structure dust settling tank with foreign matter separating function

Technical Field

The utility model belongs to the technical field of environmental dust reduction detection, and particularly relates to a double-layer structure dust reduction cylinder with a foreign matter separation function.

Background

The dust settling tank is suitable for monitoring the atmospheric dust settling amount and sampling of acid rain, and is also suitable for analysis and assay, laboratory waste liquid tank and cleaning liquid storage. When in use, the dust falling tank is capped and clamped to a sampling point, the cap is taken down for sampling, and a small amount of water can be added into the tank in order to prevent dust falling into the dust falling tank from being blown away by wind; in summer, a small amount of copper sulfate solution can be added to prevent the growth of microorganisms and algae; during the freezing season, proper amount of ethanol solution may be added as antifreezing agent. The sampling time is generally one month, after sampling is finished, the dust settling tank is returned to a laboratory, and the settling volume is calculated after evaporation, drying and weighing.

However, in the actual sampling process, some foreign matters such as leaves, dead branches, bird droppings, insects and the like easily enter the dust fall jar, when the laboratory is used for analysis and detection, the foreign matters need to be manually sorted out one by one and then collected, the working efficiency is low, the workload of analysis and detection personnel is large, and errors can be brought to analysis results due to unavoidable subjective intention of manual sorting.

In addition, in seasons where rain water is abundant, the water level in the dustfall tank often exceeds the highest limit of the dustfall tank. The sampling time is generally one month, and the dust settling tank cannot be replaced in time, so that collected dust particles overflow along with water flow, and deviation occurs to a measurement result.
