Detailed Description

The drawings in the embodiments of the invention will be combined; the technical scheme in the embodiment of the invention is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the invention; rather than all embodiments. Based on the embodiments of the invention; all other embodiments obtained by a person skilled in the art without making any inventive step; all fall within the scope of protection of the present invention.

Example 1:

referring to fig. 1-6, a chemical reaction kettle with higher stirring efficiency comprises a shell, wherein a feeding port is arranged on the shell, a rotating motor is arranged above the shell, the rotating motor is connected with one end of a rotating shaft, the other end of the rotating shaft extends to the bottom in the shell, the inner wall of the shell is fixedly connected with one end of a supporting shaft, the other end of the supporting shaft is rotatably connected with an inner wall stirring gear, and the inner wall stirring gear is arranged in an upper row and a lower row on the inner wall of the shell;

an upper stirring gear and a lower stirring gear are respectively arranged on the rotating shaft positioned in the shell, and the upper stirring gear and the lower stirring gear are respectively contacted with the inner wall stirring gears of the upper row and the lower row on the inner wall of the shell.

And a stirring rod is arranged on the rotating shaft between the upper stirring gear and the lower stirring gear.

The blade of auger on be provided with the liquid outlet hole, the inside drain pipe that is provided with of rotation axis of auger, drain pipe and liquid outlet hole intercommunication, casing top be provided with the feed liquor pipe, the feed liquor pipe pass rotation axis and stirring rod in proper order then with the feed liquor layer intercommunication of guide plate top, feed liquor layer and drain pipe intercommunication.

The gear blade of the upper stirring gear is provided with a down-flow hole, and a turbulent fan is connected in the down-flow hole.

The working principle is as follows:

when the stirring device is used, a certain solution with a large content is added through a feeding hole (not shown in the figure) in the shell until the upper stirring gear is submerged, then the rotating motor is started, the upper stirring gear, the lower stirring gear and the stirring rod are driven to rotate by the rotating shaft, so that the solution is disturbed from the horizontal direction, as shown in figure 1, the upper stirring gear and the lower stirring gear drive the inner wall stirring gear to rotate in the rotating process, as shown in figure 2, so that the solution is disturbed up and down through the rotation of the inner wall stirring gear, and the mixing is more uniform and rapid;

the stirring rod is driven by the rotating shaft to rotate, as shown in fig. 2, when the stirring rod moves to a certain direction, the upper and lower guide plates rotate under the action of the flow spreading edge to form a shape as shown in fig. 3, the solution between the guide plates and the stirring rod body passes through the turbulence holes as shown in fig. 4, the auger is arranged in the turbulence holes, so that further mixing can be realized, and as shown in fig. 4, the turbulence holes are inclined upwards, so that the mixing of the solution between the solution layers is realized;
