Material feeding device for adjusting feedstock to a reaction container

Abstract

The invention discloses a material feeding device for adjusting feedstock to a reaction container. The device includes a driving motor, a universal joint, an inlet pipe, a branch main pipe, and a reaction kettle body. The inlet pipe is stretched into the reaction kettle body and is connected to the branch main pipe. A first branch main pipe, a second branch main pipe, a third branch main pipe anda fourth branch main pipe are successively disposed on the branch main pipe. A total flow rate sensor is arranged on the inlet pipe. A first electromagnetic valve is disposed on a connection pipe between the branch main pipe and the second branch main pipe. A second electromagnetic valve is disposed on a part, between the second branch main pipe and the first branch main pipe, of the branch main pipe. A third electromagnetic valve is disposed on a connection pipe between the branch main pipe and the third branch main pipe. A fourth electromagnetic valve is disposed on a part, between the thirdbranch main pipe and the fourth branch main pipe, of the branch main pipe. In the technical scheme, by means of the driving motor and a frequency varying device, rotation frequency and rotation amplitude of the universal joint are controlled, so that excessive large rotation frequency of the universal joint is prevented and liquids are prevented from being splashed onto inner walls of the reaction kettle.

Description

technical field [0001] The invention relates to the technical field of chemical processing, in particular to a feeding device for adjusting the feeding of a reaction vessel. Background technique [0002] The reaction kettle is a container with physical or chemical reactions. The general structure of the existing reaction kettle includes a kettle body, an exhaust port, a feed port, a material outlet, a stirring device and a heating device, and the heating device is generally passed through the reactor body. A jacket is set outside the wall or heat exchange is performed through an external circulation. The main heating methods include electric heating, hot water heating, thermal oil circulation heating, far-infrared heating, external (inner) coil heating, etc.; for low boiling point reaction systems, It is not necessary to be provided with a stirring device, and the stirring device will cause an increase in cost. In addition, the existing reaction kettles used for liquid reac...

[0002] The reaction kettle is a container with physical or chemical reactions. The general structure of the existing reaction kettle includes a kettle body, an exhaust port, a feed port, a material outlet, a stirring device and a heating device, and the heating device is generally passed through the reactor body. A jacket is set outside the wall or heat exchange is performed through an external circulation. The main heating methods include electric heating, hot water heating, thermal oil circulation heating, far-infrared heating, external (inner) coil heating, etc.; for low boiling point reaction systems, It is not necessary to have a stirring device, which will increase the cost

In addition, the existing reaction kettles used for liquid reactions generally have a feeding port on the upper end of the kettle body and feed through a feeding pipe. This feeding method makes a large number of columnar liquid raw materials drop and react instantly When the main materials in the kettle contact, there will be phenomena such as uneven reaction and excessive reaction, which will directly affect the quality of the product, especially for viscous materials and large-volume reactors, this disadvantage is more prominent

At the same time, it is impossible to accurately control the amount of chemical raw material liquid added
