Abstract

The utility model provides a bottom-scraping stirring device, which includes a bottom-scraping blade arranged at the bottom of the kettle in an inclined "L" shape. The bottom-scraping blade is close to the rotating base and the arc-shaped surface of the bottom of the reaction kettle. When stirring, the material in the dead corner will be completely stirred. The utility model has the advantages of simple structure, ingenious design, no dead angle, complete stirring, clean discharging and the like.

Description

A bottom scraping stirring device

technical field

The utility model relates to a stirring device, in particular to a stirring device capable of bottom scraping and stirring.

Background technique

During production, the whole material is stirred through the stirring tank to make the distribution more uniform or the reaction more complete. However, because the rotating shaft needs to be fixedly connected to the rotating base at the bottom of the kettle, there are no rotating blades around the rotating base, and the rotating blades for stirring are all long and straight, so there is not enough space at the bottom of the kettle, so there will be dead angles near the rotating base, over there The material cannot be stirred, so that the material here cannot be stirred evenly or completely reacted. Even when discharging, solids or viscous liquids cannot be discharged cleanly.

Utility model content

The purpose of the utility model is to provide a bottom-scraping and stirring device with simple structure and ingenious design, which can completely stir the materials at the bottom of the kettle.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a bottom scraping stirring device, which includes a rotating shaft arranged in the reaction kettle, the bottom of the rotating shaft is fixed on the rotating base, and the rotating base is fixed on the reaction tank. Bottom of the pot. Bottom scraping blades are arranged on the rotating shaft close to the rotating base, and the bottom scraping blades are arranged symmetrically on both sides of the rotating shaft. After the reactor, it extends upward along the arc of the reactor to form an oblique "L"-shaped blade.

Compared with the prior art, the utility model has the following beneficial effects:

1. The structure is simple, the design is ingenious, and it is convenient for large-scale manufacturing, processing and installation.

2. There is no dead angle, the mixing is complete, and the material at the bottom of the kettle near the rotating base can be stirred.

3. The discharge is clean, especially when it is solid or viscous liquid, the effect is particularly obvious.

Description of drawings

Fig. 1 is the structural representation of the bottom scraping and stirring device of the present invention at the bottom of the kettle.

detailed description

In order to further illustrate the technical means adopted by the utility model and the technical effects achieved, the following will be described in detail in conjunction with the accompanying drawings and embodiments.

The utility model proposes a bottom scraping stirring device, referring to Fig. 1, it includes a rotating shaft 10 arranged in the reactor, the bottom of the rotating shaft 10 is fixed on the rotating base 20, and the rotating base 20 is fixed on the reaction Bottom of the pot. Bottom scraping blades 30 are arranged on the rotating shaft 10 close to the rotating base 20, and the bottom scraping blades 30 are symmetrically arranged on both sides of the rotating shaft 10, and the bottom scraping blades 30 are arranged along the rotating base. The outer side of 20 extends downwards until close to the reactor, and then extends upward along the arc of the reactor to form an oblique "L"-shaped blade.

The working principle of the utility model is: the bottom scraping blade is close to the arc surface of the rotating base and the bottom of the reaction kettle, and the bottom scraping blade will completely stir the materials in the dead corner when rotating and stirring.

The above description has fully disclosed the specific implementation manners of the present utility model. It should be pointed out that any changes made by those skilled in the art to the specific embodiments of the utility model will not depart from the scope of the claims of the utility model. Correspondingly, the scope of the claims of the present utility model is not limited only to the foregoing specific embodiments.
