At present, the sampling of the reactor is generally carried out through a sampling device. The sampling device samples from the bottom valve of the reactor or the top valve of the reactor or the position of the pipeline during the reaction process. However, during the sampling process, it is often impossible to recover the redundant samples, which will cause a lot of waste. samples, increased production costs

The invention discloses an automatic sampling device for a reaction kettle. The automatic sampling device comprises a sampling tube arranged on the side wall of the lower end of the reaction kettle; the sampling tube is provided with a transfer bottle, a pressure release valve, a first pressure sensor, a shut-off valve and a second pressure sensor from left to right; the transfer bottle is provided with a central controller; the transfer bottle comprises an opening part which is sleeved and fixed on the sampling tube; a bottle body part is fixed at the upper end of the opening part; a step hole with an open upper side open is formed on the bottle body part; an automatic push-back device is arranged in the step hole; a discharge pipe communicating with the step hole is fixed to the side wall of the bottle body part; the discharge pipe is provided with a discharge valve; a through hole communicating with a sampling cavity and an inner hole of the sampling tube is formed in the opening part; the through hole and a small piston are coaxially arranged; and a second push-back device is arranged at the left end of the sampling tube. The automatic sampling device for the reaction kettle provided by the invention can conveniently and quickly carry out sampling, and can automatically push redundant samples back into the reaction kettle, which greatly reduces the waste degree of raw materials.
Description
Technical field: [0001] The invention relates to the technical field of chemical machinery, in particular to an automatic sampling device for a reaction kettle. Background technique: [0002] At present, reactors are widely used in the production of polyester resins. During the production process, samples need to be taken in the reactors to detect the conditions in the production process of polyester resins. At present, the sampling of the reactor is generally carried out through a sampling device. The sampling device samples from the bottom valve of the reactor or the top valve of the reactor or the position of the pipeline during the reaction process. However, during the sampling process, it is often impossible to recover the redundant samples, which will cause a lot of waste. samples, increasing production costs. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an automatic sampling device for...
