Liquid sampling device based on p-methylphenol production detection

Abstract

The invention discloses a liquid sampling device based on p-methylphenol production detection, and relates to the technical field of chemical production equipment. The device comprises a containing container, wherein a handle is arranged on one side of the containing container; a drain hole is formed in the bottom of the container, and a surrounding edge surrounding the peripheral edge of the drain hole is arranged at the outer bottom of the container; the bottom end of the drainage pipe is connected with a barrel through a horn pipe section, a traction rope is fixed to the center of the floating ball, and through holes are formed in the side face and the bottom face of the barrel; the other end of the traction rope penetrates through the drainage hole and is connected with the handle. According to the device, early-stage containing is carried out through the large-capacity containing container, and the liquid is discharged into the sampling container through the containing container,so that the problems that the liquid overflows or splashes, the bottom surface is polluted or the liquid splashes to the skin, and the sampling safety is influenced in actual sampling are solved; andmeanwhile, quantitative sampling is realized according to the selection of the volume and the height of the sampling container.

Description

technical field [0001] The invention belongs to the technical field of chemical production equipment, in particular to a liquid sampling device for production detection based on p-cresol. Background technique [0002] In the process of chemical synthesis, the control of the reaction process and the end point of the reaction is a crucial factor. This process directly affects the yield of the reaction and the quality of the product. In order to clearly know the state of the material reaction, it is required to frequently take samples to detect some corresponding indicator, and the state of the reaction material is more complicated, the material is often dangerous, and the sampling process is more dangerous; the existing sampling method includes opening the liquid outlet of the reaction kettle for sampling, and the existing sampling container often uses a beaker with a smaller volume. Small containers may easily cause liquid to overflow or splash during actual sampling, contami...
