Sampling equipment for resin production based on polyesterification reaction

Abstract

The invention discloses sampling equipment for resin production based on polyesterification reaction. The whole sampling device is mounted and placed through a mounting pipe; the mounting pipe is mounted in the middle of the bottom of the sampling chamber, and a vacuum pump is fixed to the top of the sampling chamber; comprising six storage cavities, the six storage cavities are formed in the sampling chamber at equal intervals with the circle center of the sampling chamber as the circle center, and detection hoppers with the interiors of hollow structures are arranged in the storage cavities; and the lower adjusting block is mounted in the mounting pipe in an attached and sliding mode, and the top end of the lower adjusting block is connected with the upper adjusting block through a supporting rod. The sampling equipment for resin production based on polyesterification reaction is provided with six storage cavities, so that the whole sampling device can continuously perform sampling work for six times without cleaning, and meanwhile, matched with rotation of a lower adjusting block and an upper adjusting block, sampled materials can be conveniently conveyed into one of the storage cavities, and the sampling equipment is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of resin production, in particular to a sampling device for resin production based on polyesterification reaction. Background technique [0002] Resin is divided into synthetic resin and natural resin. Synthetic resin is an important raw material for plastic production. Resin needs to be sampled and retested every 30 minutes during the polyesterification process to determine whether the acid value and viscosity are qualified. The existing sampling device There are still some problems when using it, such as: [0003] 1. The patent name disclosed by the announcement number "CN208187777U" is "Resin Reactor Sampling Device". Problems with residual resin clogging sampling tubes. To solve the problem of sampling pipe blockage, it is necessary to use unblocking tools. These tools and operations will bring some dangers, such as the valve being damaged and unable to close, or resin spraying out with the unblocking ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of resin production based on polyesterification reaction sampling equipment, to solve the problem that the sampling device on the market proposed by the above-mentioned background technology has only one sampling tube, when sampling every 30 minutes, it is necessary to carry out the internal sampling of the sampling tube. Cleaning and reusing will make the operation more complicated. The existing sampling device has a simple structure and only simply samples the resin. After sampling, the resin needs to be poured into the detection area for viscosity detection, which takes a long time. , the problem of time-consuming and labor-intensive operation
