Sample washing device

Abstract

The invention discloses a sample washing device which comprises a main pipe, a liquid storage barrel and a plurality of dividing pipes, wherein the main pipe is positioned above the liquid storage barrel, the upper part of the main pipe is connected with a sample room, and the lower part of the main pipe is connected with the liquid storage barrel; a plurality of dividing openings are uniformly formed in the side part of the liquid storage barrel, and each dividing pipe is connected to the corresponding dividing opening; the tail end of each dividing pipe is connected with a nozzle with a downward opening; each dividing pipe is further connected with a sample placing rack which is erected right below the nozzles. An experimental medium is conveyed to the liquid storage barrel by virtue of the main pipe, then is divided to the dividing pipes, and is finally sprayed out from the nozzle connected to the tail end of each dividing pipe. As the sample placing rack is further connected to the dividing pipes and is located right below the nozzles, a liquid sprayed out from the nozzles can be accurately sprayed to a sample, so that troubles that experimenters repeatedly adjust positions of the nozzles and the sample are avoided. Moreover, the spraying angle and distance are adjustable, so that the whole experimental process is relatively convenient and efficient to operate.

Description

technical field [0001] The invention relates to a sample scouring device, which is suitable for high flow velocity scouring and corrosion simulation experiments. Background technique [0002] At present, in the sample scouring device used in the naphthenic acid scouring corrosion simulation experiment, the nozzle is separated from the sample holder. Since the sample chamber of the sample flushing device is sealed and invisible, the position of the sample cannot be guaranteed to be directly under the nozzle. Before starting the test, it is necessary to repeatedly disassemble and debug to ensure that the liquid sprayed by the nozzle can be sprayed on the sample, and there is no guarantee that the position of the nozzle will not change during the experiment. Once it changes, it will seriously affect the experimental results and even lead to fail. In addition, the number of samples placed on the traditional sample holder is small, generally only 1 to 2, resulting in low workin...

Since the sample chamber of the sample flushing device is sealed and invisible, the position of the sample cannot be guaranteed to be directly under the nozzle

Before starting the test, it is necessary to repeatedly disassemble and debug to ensure that the liquid sprayed by the nozzle can be sprayed on the sample, and there is no guarantee that the position of the nozzle will not change during the experiment. Once it changes, it will seriously affect the experimental results and even lead to fail

In addition, the number of samples placed on the traditional sample rack is small, generally only 1 to 2, resulting in low working efficiency of the sample flushing device
