Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, and particularly relates to a grinding type composite stirring device for producing mold powder for continuous casting. Background Technique

[0002] Mold powder for continuous casting is a material placed on the molten steel surface in the mold during the continuous casting process to keep warm, prevent oxidation and absorb non-metallic inclusions. During the production process, it needs to be ground and stirred to meet the subsequent use standards, so a grinding type composite stirring device is required.

[0003] According to a grinding type composite mixer for producing mold powder for continuous casting (authorization announcement number: CN 210229678 U) disclosed on the patent network, it is described that "the utility model discloses a grinding type composite mixer for producing mold powder for continuous casting, including a motor, characterized in that: a hydraulic coupler is connected to the transmission shaft of the motor, the hydraulic coupler is fixed on the mixer cover, the end of the hydraulic coupler is connected to a main shaft, the main shaft is provided with threads, a rotating screw disk is rotationally screwed on the threads, the end of the main shaft is provided with an end disk, a rotating disk is provided on the end disk, a spring is provided between the rotating disk and the rotating screw disk, the side of the rotating screw disk is rotationally connected to an upper support rod, the upper support rod is rotationally connected to a lower support rod, the end of the lower support rod is rotationally connected to the rotating disk, and fan blades are provided on the upper support rod and the lower support rod. Through the speed change ability of the hydraulic coupler, pressure is given in the early stage of stirring to deform the upper support rod and the lower support rod, increasing the range of rotational stirring, thereby increasing the stirring uniformity."

[0004] Regarding the above description content, the applicant believes that the following problems exist:

[0005] During the use of this utility model, since the device adds power to the output of the motor through a hydraulic coupler, the rotating compass moves outside the thread while the fan blades are stirring, thereby driving the fan blades to generate a position movement and increasing the stirring area. However, after stirring for a certain period of time, the rotating screw disk reaches the bottom of the thread and the position will no longer change. Therefore, the fan blades cannot continuously change their positions during continuous stirring, which has certain limitations. Therefore, it is necessary to improve a grinding type composite stirring device for producing mold powder for continuous casting to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a grinding type composite stirring device for producing mold powder for continuous casting to solve the problems raised in the above background technique.

The stirring shaft 215 stirs the materials through the stirring blades 216 to make them evenly mixed, with high mixing efficiency. There are three stirring blades 216, and the three stirring blades 216 are sequentially distributed from top to bottom on the outside of the stirring shaft 215.

There are two limiting shafts 221, and the two limiting shafts 221 are symmetrically fixedly connected to the bottom of the mixing tank 1. Limiting holes are formed at the corresponding positions of the stirring shaft 215 for the connecting block 224, and the connecting block 224 is rotatably connected inside the limiting holes. The movement of the movable plate 222 is limited by the two limiting shafts 221, which can prevent the movable plate 222 from rotating and make the movable plate 222 move only linearly up and down.
