Adjustable common circulating sampler for connection sampling and use method thereof

Abstract

The invention provides an adjustable common circulating sampler for connection sampling. The adjustable common circulating sampler comprises a sampler main body, wherein a partition plate is mounted in the sampler main body, a discharging pipe is mounted at the connecting position of the sampler main body and the partition plate, a valve is mounted on the discharging pipe, an adjusting mechanism is arranged in the discharging pipe, an ejection mechanism is arranged in the sampler main body, the adjusting mechanism comprises a piston, a sliding groove is formed in the discharging pipe, the piston is installed in the sliding groove, a through discharging hole is formed in the top of the piston, an adjusting pipe used for being connected with a sampling bottle is fixed to the bottom of the piston, the inner diameter of the adjusting pipe is communicated with the discharging hole, a limiting disc is fixed to the adjusting pipe, a force application rod is installed on the limiting disc, a sealing plate is fixed to the bottom of the discharging pipe, a guide hole used for guiding the adjusting pipe is formed in the sealing plate, and a containing hole used for positioning the sampling bottle is formed in the lower side of the inner wall of the sampler main body.The adjustable common circulating sampler of the invention is reasonable in structure, convenient to combine and mount, convenient to adjust and sample, and convenient to take and place.

Description

technical field [0001] The invention relates to a common circular sampler for adjustable connection sampling and a usage method thereof, belonging to the technical field of common circular samplers. Background technique [0002] Ordinary circulation sampler adopts explosion-proof closed circulation pump professionally manufactured by Tide, which greatly improves the overall reliability, safety and long-term operation performance. The sampler is powered by compressed air, and a flow distributor is set inside to ensure the accuracy of multi-channel circulation, reduce the cycle time, improve the cycle accuracy, and reduce the loss of air source. [0003] In the prior art, when the existing ordinary circulating sampler is in use, the sampling bottle is generally suspended in the air and connected to the discharge pipe. The connection is easily damaged after long-term use, and it is not convenient to adjust the height of the adjustment pipe and connect the sampling bottle. Samp...

Problems solved by technology

[0003] In the prior art, when the existing ordinary circulating sampler is used, the sampling bottle is generally suspended and connected to the discharge pipe, and the connection is easy to use for a long time. Damaged, it is inconvenient to adjust the height of the adjustment tube and connect to the sampling bottle for sampling, and it is not convenient to position and take out the sampling bottle, which affects the progress of sampling. Now there is an urgent need for an adjustable connection sampling ordinary circulation sampler to solve the problem The above problems
