Description

Technical Field

[0001] The utility model relates to the technical field of stirring structures of stirring kettles, and more specifically, the utility model relates to an integrated stirring and discharging structure for a reaction kettle. Background Art

[0002] Generally speaking, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Generally, it is composed of several feed inlets, one discharge outlet, a stirrer, a tank body, etc. The stirrer of the reaction kettle mixes the materials in the tank body. Some reaction kettles are also provided with detection elements such as cooling or heating devices or liquid level gauges to detect the reaction conditions of the materials in the reaction kettle.

[0003] For an existing reaction kettle, such as the stirring device of a cubic reaction kettle with the publication number CN207641469, key grooves are provided on the inner walls of the first impeller cylinder and the second impeller cylinder, and fixing keys corresponding to the two key grooves are respectively provided at corresponding positions on the stirring shaft. Fixing bolts are respectively provided between the first impeller cylinder and the second impeller cylinder and the stirring shaft. With the above technical solution, the first impeller cylinder and the second impeller cylinder are respectively fixedly installed on the stirring shaft through fixing bolts, which is stable and reliable. The fixing keys on the stirring shaft cooperate with the key grooves on the first impeller cylinder and the second impeller cylinder. In this way, when the stirring shaft drives the stirring paddle group to rotate, the relative stability between the stirring shaft and the stirring paddle group is relatively good: by setting the stirring shaft to be able to lift during stirring, the stirring paddle group can lift to stir the materials in the reaction kettle, and the stirring effect is better; by sequentially arranging a straight-blade stirrer and an inclined-blade stirrer on the stirring shaft, the two cooperate to stir the substances in the reaction kettle, and the stirring effect is better.

[0004] However, the existing reaction kettle lacks an integrated stirring and discharging structure, making it impossible to utilize the power of stirring rotation for discharging, resulting in low discharging efficiency of the reaction kettle. Moreover, when encountering finished products with poor fluidity, the discharging efficiency will be further reduced. Therefore, the existing reaction kettle needs to be further improved. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the technical problem in the prior art that the power of stirring rotation cannot be utilized for discharging, resulting in low discharging efficiency of the reaction kettle.

[0006] The purpose and efficacy of the utility model are achieved by the following specific technical means:

[0007] An integrated stirring and discharging structure for a reaction kettle, comprising a kettle body. A driving motor is installed in the middle of the upper end of the kettle body. A feeding port is installed on the upper side of the kettle body. A discharging port is installed in the middle of the lower side of the kettle body. A stirring rod is installed in the middle of the inner part of the kettle body. The upper end of the stirring rod is connected to the output end of the driving motor. A discharging baffle is arranged at the position corresponding to the discharging port at the lower end of the inner part of the kettle body. A discharging screw is arranged at the bottom of the stirring rod. The discharging screw enters the inner sides of the discharging baffle and the discharging port. Two discharging baffles are symmetrically arranged at the bottom of the kettle body. There is a certain interval between the symmetrically arranged discharging baffles. An extension plate is installed on the bottom of the kettle body corresponding to the outside of the discharging baffle. A rotating sleeve is installed on the outside of the lower end of the stirring rod of the kettle body. The upper end of the extension plate is fixedly connected to the lower side of the rotating sleeve. The inner side of the rotating sleeve is in contact with the outside of the stirring rod. A spring is installed on the inner side of the rotating sleeve. One side of the spring facing the outside of the stirring rod is connected with a spherical limiting block. A limiting groove corresponding to the spherical limiting block is arranged on the outside of the stirring rod.

[0008] Further, mounting bolts are arranged inside the upper end of the rotating sleeve. Annular grooves are arranged on the stirring rod corresponding to the mounting bolts. One end of the mounting bolt enters the inner side of the annular groove.

[0009] Further, the discharging baffle is arranged in a semi-circular arc shape. The extension plate is arranged in an arc shape and is arranged at the interval of the discharging baffle.

[0010] Further, convex blocks are arranged on the outside of the discharging baffle on the side opposite to the extension plate.

[0011] Further, the limiting groove is semi-circular. One-third of the outside of the spherical limiting block enters the inner part of the limiting groove. Beneficial effects

[0012] An integrated stirring and discharging structure for a reaction kettle has the following beneficial effects:

[0013] 1. By installing a discharging port in the middle of the lower side of the kettle body, a stirring rod in the middle of the inner part of the kettle body, connecting the upper end of the stirring rod to the output end of the driving motor, arranging a discharging baffle at the position corresponding to the discharging port at the lower end of the inner part of the kettle body, arranging a discharging screw at the bottom of the stirring rod, and the discharging screw entering the inner sides of the discharging baffle and the discharging port, and two discharging baffles being symmetrically arranged at the bottom of the kettle body with a certain interval between the symmetrically arranged discharging baffles, when the mixing and stirring inside the reaction kettle are completed, the reaction product can enter the inner side of the discharging port from the interval of the discharging baffle, and then the stirring rod is used to drive the discharging screw to rotate, so as to greatly improve the discharging efficiency of the reaction product.

[0014] 2. On one side of the discharge baffle outside the relative extension plate, there is a convex block. A rotating sleeve is installed on the outer side of the lower end of the stirring rotating rod of the kettle body. The upper end of the extension plate is fixedly connected to the lower side of the rotating sleeve. The inner side of the rotating sleeve fits with the outer side of the stirring rotating rod. A spring is installed on the inner side of the rotating sleeve. One side of the spring facing the outside of the stirring rotating rod is connected with a spherical limiting block. A limiting groove corresponding to the spherical limiting block is arranged on the outer side of the stirring rotating rod, and the limiting groove is semicircular. One-third of the outside of the spherical limiting block enters the inside of the limiting groove. A sealing cushion layer is arranged on the outside of the extension plate. Then, when the stirring rotating rod rotates clockwise, the rotating sleeve and the extension plate can be driven to rotate by the spherical limiting block, opening the interval of the discharge baffle, so that the reaction product can be discharged normally. When rotating counterclockwise, it can be closed for subsequent reactions. Among them, by providing the convex block, the rotation of the rotating sleeve and the extension plate can be stopped after rotating a certain angle, and the spherical limiting block can squeeze the spring to contract inward when continuing to rotate and move in the limiting groove, thus not affecting the normal rotation of the stirring rotating rod.
