Problems solved by technology

The existing sampling device adopts a device with a pipeline and a valve, and there is a sampling dead angle. After one sampling, the residual slurry in the pipeline cannot be removed and remains in the pipeline. When sampling next time, it needs to be discharged for a period of time. The sampling volume and sampling accuracy Unable to control
If sampling is not carried out for a long time, the slurry solid deposits in the pipeline and may not be removed. In the long run, the pipeline is easy to be blocked and the sampling hole is scrapped.

Abstract

A variable anti-blocking slurry sampling device is disclosed. The device includes a sampling cylinder. The sampling cylinder is connected to a pipeline type check valve and a swing check valve. The pipeline type check valve is connected to a storage container. The swing check valve is connected to a sampling port. Through lifting a circular rubber sheet in the sampling cylinder by a pinch bar, the pipeline type check valve is opened and the slurry flows into the sampling cylinder, and when the pinch bar reaches a limiting position, through lifting the pinch bar upward, the pipeline type check valve is closed, the swing check valve is opened and the slurry flows out from the sampling port, and therefore a sampling objective is achieved. Through changing the position of the circular rubber sheet, the sampling volume is changed and a variable sampling objective is achieved. The device is simple in structure, convenient to manufacture, capable of accurate sampling according to needs, and free of dead angles. No slurry is left in the sampling cylinder after sampling is finished. In addition, a lever principle is adopted so that the device is convenient and labor-saving.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a variable volume anti-blocking slurry sampling device. Background technique [0002] At present, in the field of slurry transportation, the characteristic analysis of slurry is the technical guarantee to ensure the safety of transportation, and the accuracy of slurry sampling is related to the correctness of analysis results. The existing sampling device adopts a device with a pipeline and a valve, and there is a sampling dead angle. After one sampling, the residual slurry in the pipeline cannot be removed and remains in the pipeline. When sampling next time, it needs to be discharged for a period of time. The sampling volume and sampling accuracy Uncontrollable. If sampling is not carried out for a long time, the slurry solid deposits in the pipeline may not be able to be removed. In the long run, it is easy to block the pipeline and cause the sampling hole to be scrapped....
