Description

A resin reactor sampling device

technical field

The utility model relates to the technical field of chemical industry. Specifically relates to a resin reactor sampling device, which can be used for production sampling of alkyd resins, polyester resins, acrylic resins and epoxy resins other than polyurethane resins.

Background technique

Sampling and analysis are usually required in the resin production process. The sampling port of the existing resin reactor is located at the bottom side of the reactor and controlled by a valve. When sampling, open the valve slowly, and wait for the material to flow out and clean the sampling port before sampling. Because the temperature of the material is as high as 200 degrees, the viscosity is low, and the pressure is strong, it is easy to splash out at high speed and cause personal injury, which poses a safety hazard; the material for cleaning the sampling port directly flows into the waste bin, resulting in waste of material and energy.

Contents of the invention

The problem to be solved by the utility model is to provide a resin reactor sampling device, which can avoid waste of materials and avoid the danger of being splashed by high-temperature and high-pressure materials during sampling.

The technical solution provided by the utility model is: a resin reactor sampling device, including a sampling tube leading into the resin reactor, a buffer tank connected with the sampling tube, a vacuum tank connected with the buffer tank, and a control valve is arranged on the sampling tube 1. The vacuum tank is provided with a drain pipe 1 leading to the resin reaction kettle, and the drain pipe 1 is provided with a control valve 2; the sampling pipe is provided with a lofting pipe, and the lofting pipe is located between the control valve 1 and the buffer tank. A control valve 3 is arranged on the pipe, a liquid receiving bucket is arranged below the lofting port of the lofting pipe, and the liquid outlet of the liquid receiving bucket is connected with a liquid discharge pipe 2 leading into the resin reactor.

The above-mentioned discharge pipe 2 is provided with a control valve 4 .

The above-mentioned sampling tube is provided with an observation mirror.

The utility model adopts the above-mentioned structure, controls the valves when sampling, vacuumizes to make the material rise slowly through the pipeline, controls the valves after stopping the vacuum, and takes samples from the sampling port for detection. Clean the material in the pipeline and sampling port before sampling. After the sampling, the residual material in the tank and pipeline can be returned to the reactor through the first and second drain pipes, avoiding material waste. More importantly, it can prevent people from being splashed by high-temperature and high-pressure materials, eliminating potential safety hazards.
