Background

The synthesis reaction refers to a reaction process and a reaction mode that a plurality of substances only produce one chemical product through chemical reaction, and generally the synthesis reaction is completed through a synthesis reaction kettle, before the synthesis reaction is carried out, solid reaction raw materials are required to be put into the synthesis reaction kettle through a feed port, and if the solid raw materials contain nonfriable blocky hardening raw materials or other foreign matters, the solid raw materials can enter the synthesis reaction kettle along with the raw materials, so that the synthesis reaction materials are polluted, and the reaction process is influenced.

Some reactions release heat in the synthesis reaction, some synthesis reactions need to be heated in the reaction process, and the raw material feeding ports of some reaction kettles are arranged in an open mode. At this time, the temperature in the synthesis reaction kettle will gradually rise, along with the rise of the temperature, the surface layer of the synthesis reaction liquid will form a mixed gas containing a large amount of water vapor and chemical substances, the mixed gas escapes from the liquid phase interface to enter the gas phase, if the mixed gas escapes from the synthesis reaction kettle to the atmosphere, the environment is polluted, the consumption of products is increased, and along with the escape of the mixed gas to the outside, the solvent water in the liquid phase reaction system is reduced, the proportion of the materials participating in the synthesis reaction is changed, the synthesis reaction is further changed, and the quality of the products is affected.

There are also some filter devices or sealing covers arranged at the raw material feeding port. When the filter device is used, the sealing cover body is often closed because the filter device is greatly influenced, and the filter device can be closed after being taken out; there are also some phenomena that the filter device is arranged smaller and even falls into the reaction kettle. Therefore, the inventor makes some attempts to set a filtering device and a sealing cover at the raw material feeding port so as to explore new possibilities.
