Description

Simple and convenient swift reation kettle material sampling device

Technical Field

The utility model relates to a chemical industry check out test set field specifically is a simple and convenient swift reation kettle material sampling device.

Background

In chemical production, the temperature of materials in a reaction kettle is often as high as more than 200 ℃, and the reaction materials are viscous liquid. Due to the process requirements, operators need to take out liquid from the high-temperature reaction kettle at any time, and the reaction process is detected according to various indexes of the material state.

The conventionally designed reaction kettle sampler is an iron pipe which is equal to the inner depth of the reaction kettle and is made of a section of closed stainless steel material, and a small hole is formed close to the closed end. When the sampler is immersed in the liquid material, the liquid will flow in through the pre-formed openings in the bottom. When the liquid volume is full, an operator lifts the sampler from the reaction kettle and pours the taken materials out from the opening. The design is simple and light, and only the hole is arranged at the top of the reaction kettle. But the disadvantages are also more pronounced. According to long-term production detection, the sampling accuracy of the traditional sampler is low. Because during sampling, the small pores of the sampler are first exposed to a liquid (by-product or other affecting liquid) that is less dense and floats on the surface of the reaction mass. When the take-off pipe sinks to the bottom of the kettle, the real state of the reaction of the materials cannot be monitored because the liquid with low density already exists in the take-off pipe and the pipe. And therefore gradually approaches elimination.

The novel sampler is arranged at the bottom of a reaction kettle at present, and materials are taken out by utilizing the comprehensive action of a vacuum pump and a high-pressure air pump. The precision is higher than the traditional sampling. The defect problem mainly focuses on the aspect of equipment modification, and because the existing part is the reaction kettle provided with the traditional detector, and the sampling is carried out on the top of the reaction kettle, the novel sampler needs to be modified to form a hole on the bottom of the reaction kettle, so that a lot of time and money are consumed.
