Description

Technical Field

[0001] The invention relates to the technical field of wastewater sampling, and in particular to a high-efficiency industrial wastewater sampling device and method. Background Art

[0002] Industrial wastewater refers to water containing harmful substances produced during the industrial production process, usually including various chemicals, heavy metals, waste solvents, toxic and harmful gases or solid wastes. In order to ensure that industrial wastewater meets the emission standards, it needs to be sampled and tested.

[0003] When sampling industrial wastewater, samples are usually obtained directly from the surface of the water body through a water sampling device. However, due to the possible differences in physical and chemical properties such as temperature, density, dissolved oxygen, and pollutant concentration between different water layers, only sampling the upper layer of the water cannot fully reflect the pollution situation of the entire water body.

[0004] In addition, the flow rate of the water body will also affect the sampling process. For water bodies with slower flow rates, a single sample can better represent the pollution situation of the water body. However, for fast-flowing water bodies, the distribution and concentration changes of pollutants are more complex, so intermittent multiple sampling is required. The actual sampling method requires manual judgment, and the operation is more cumbersome.

[0005] Therefore, an efficient industrial wastewater sampling device and method are proposed. Summary of the invention

[0054] Example 2

[0055] An efficient industrial wastewater sampling method, based on Example 1, specifically comprises the following steps:

[0056] S1, anchor the mounting base 101 at a fixed position in the water body. When sampling, rotate the locking knob 4042 outward so that the locking knob 4042 no longer presses against the rotating shaft of the third synchronous wheel 402, and rotate the hand crank handle 405. The hand crank handle 405 drives the corresponding third synchronous wheel 402 to rotate. The two sets of third synchronous wheels 402 cooperate to drive the lifting synchronous belt 403 to rotate.

[0057] S2, rotating the turntable 107, the turntable 107 drives the spline shaft 105 to rotate, the spline shaft 105 drives the spline sleeve 204 to rotate, the spline sleeve 204 drives the second synchronous wheel 205 to rotate, the second synchronous wheel 205 drives the first synchronous wheel 202 to rotate, and then opens the right-angle ball valve 201 or closes the right-angle ball valve 201. When sampling, the turntable 107 is rotated to open the right-angle ball valve 201, and the wastewater enters the right-angle ball valve 201;

[0058] S3, when the water flow rate is slow, the impact force of the water on the ball shell 307 is small, and the ball shell 307 cannot pull the clamping column 304 out of the positioning groove of the connecting shaft 208 through the connecting rope 305. At this time, the connecting shaft 208 does not rotate, and the wastewater directly enters the sample cavity of the shell 206 through the water channel of the core column 207. The sampling pump directly pumps out the sample, and the sample can be collected through the sample container;

[0059] S4, when the water flow speed is fast, the impact force of the water on the ball shell 307 is relatively large, and the ball shell 307 pulls the card column 304 through the connecting rope 305 to push the positioning groove of the connecting shaft 208.
