Description

Reactor with central stirring rod

technical field

The utility model relates to equipment for preparing acrylate, in particular to a reaction kettle with more uniform stirring.

Background technique

Reactor is a necessary equipment in the preparation of acrylate, but due to the high viscosity of raw materials and products, the full progress of the reaction depends to a large extent on the effect of stirring. No matter the existing stirring paddle is a three-blade or two-blade stirring paddle, it is to promote the overall circulation of the materials in the reactor, and it is difficult for the raw materials to be mixed in the reactor to fully react in a short time. The reason is that a certain raw material needs to be in contact with other raw materials to react, but the reactants basically flow together with the propulsion of the stirring paddle in the kettle, and the probability of mutual contact is small and the contact time is short. Even if the reaction environment satisfies the conditions, the reaction time is still not enough to fully react the reactants.

Contents of the invention

The purpose of the utility model is to provide a reaction kettle with a middle stirring rod which can increase the contact time of materials in the reaction kettle and improve the reaction efficiency.

In order to achieve the above object, the utility model includes, the motor, the rotor at the bottom of which is connected to the rotating shaft through a clutch, a coupler, and a speed reducer in sequence, and the motor, clutch, coupler and speed reducer are all fixed in the reactor The upper end of the shell coincides with the center line of the reactor shell, and the part where the rotating shaft penetrates into the reactor shell is fixed with an upper stirring paddle and a lower stirring paddle, and the propulsion direction of the upper stirring paddle is opposite to that of the lower stirring paddle ; A vertical bevel gear is set on the rotating shaft between the upper stirring paddle and the lower stirring paddle; a horizontal stirring rod is respectively arranged on both sides of the bevel gear, and one end of the stirring rod has a The other end of the gear-coordinated transverse bevel gear is fixedly connected with the inner ring of a bearing whose outer ring is fixed on the inner surface of the reactor shell, and more than two stirring blades are set on the stirring rod.

Further, a support seat is fixed on the inner surface of the bottom end of the reactor shell, the top end of the support seat is fixedly connected with the outer ring of a bottom bearing, and the bottom of the rotating shaft is fixedly connected with the inner ring of the bottom bearing.

Further, a heating device is fixed on the outer surface of the reactor shell.

Preferably, the top of the reactor shell is provided with a feeding port, an inspection hole, and a discharge port at the bottom.

Since a stirring rod with stirring blades is added between the upper stirring paddle and the lower stirring paddle, when the material is pushed to the middle by the upper stirring paddle and the lower stirring paddle, the stirring blades on the stirring rod push the upper and lower stirring paddles. The materials are fully mixed, thereby greatly increasing the probability and time of material contact in the area where the stirring rod is located, thereby effectively improving the reaction efficiency and shortening the reaction time.
