However, the stirring rod moves in a clockwise direction, which cannot achieve full mixing of the raw materials in different proportions. This results in uneven mixing of the lining material and affects its performance. Therefore, based on the above-mentioned defects in the prior art, this application proposes to design a stirring device for medium-frequency furnace lining material processing that improves the material mixing effect and solves this defect in the prior art. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a stirring device for processing lining materials in medium-frequency furnaces.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a stirring device for processing lining materials in a medium-frequency furnace, comprising a stirring base for holding various raw materials to be stirred and mixed, a stirring motor on the stirring base, the stirring motor driving a stirring rod to rotate circumferentially against the inner wall of the stirring base to stir the raw materials, a screw conveyor inside the stirring base for spirally conveying the stirred raw materials to the upper part, wherein the stirring rod rotates around the screw conveyor, and a dispersing disc is provided on the screw conveyor for discharging the raw materials conveyed by the screw conveyor, which are discharged through multiple dispersing holes distributed on the dispersing disc; wherein the output shaft of the stirring motor is provided with a dispersing component for dispersing the raw materials discharged into the dispersing disc.

[0006] By adopting the above technical solution, various raw materials in the mixing seat are mixed and stirred at the same time. The mixing material is conveyed to the dispersing plate by a screw conveyor. The dispersing component is used to disperse the mixed material conveyed to the dispersing plate and disperse it through the dispersing hole for further mixing and stirring, thereby improving the mixing effect between the raw materials.

[0016] By adopting the above technical solution, the mixing material entering from the feed inlet can be conveyed to the discharge cylinder by driving the screw conveyor shaft to rotate the screw blades on the drive motor.

[0017] Optionally, the dispersing component includes a pair of connecting rods mounted on the connecting rod, and a dispersing plate that fits against the inner wall of the dispersing disk is mounted on the connecting rod.

[0018] By adopting the above technical solution, it is convenient to simultaneously drive the dispersing plate on the connecting rod to rotate when the stirring motor drives the connecting rod to rotate, so that the stirring material entering the dispersing plate is spread out and discharged.

[0019] Optionally, the interior of the dispersion disk is an annular cavity, and the width of the dispersion plate is equal to the width of the annular cavity.

[0020] By adopting the above technical solutions, the fit is improved, ensuring the dispersion and dispersing effect of the mixed material during rotation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] After pouring various raw materials into the mixing base, the mixing motor is started to drive the mixing rod to mix the raw materials. At the same time, the mixture is conveyed to the dispersing disc by a screw conveyor. The mixing motor works in conjunction with the dispersing components to rotate, thereby dispersing the mixture that has entered the dispersing disc and discharging it through the dispersing holes into the mixing base. The mixing of materials is achieved during the discharge process, which also improves the fluidity of the materials and effectively enhances the mixing effect. Attached Figure Description

[0030] like Figure 1 As shown in Figure 4, the specific solution of the embodiment is as follows: A stirring device for processing lining material of medium frequency furnace includes a stirring seat 1 for placing various raw materials for stirring and mixing. The bottom wall of the inner cavity of the stirring seat 1 is inclined to ensure that the mixture is discharged along the inclined surface and to avoid the mixture adhering to the inner wall of the stirring seat 1. The bottom of the stirring seat 1 is connected to a discharge pipe 3 for discharging the stirred mixture. A support seat 2 is installed and fixed on the stirring seat 1 to support and stabilize it on the ground.

[0031] The unloading pipe 3 is externally connected to an automatic switching valve that controls the switching of the unloading pipe 3.

[0032] It should be added that by opening the automatic switch valve, the molded material mixed by the mixing seat 1 can be discharged and collected through the discharge pipe 3.

[0033] The stirring base 1 is equipped with a stirring motor 4, and the output shaft of the stirring motor 4 and the screw conveyor are both concentric with the stirring base 1.

[0034] The stirring motor 4 drives the stirring rod 5 to rotate in the stirring seat 1 to stir the raw materials. The stirring seat 1 is equipped with a screw conveyor to convey the stirred raw materials to the top. The stirring rod 5 rotates around the screw conveyor. The screw conveyor is equipped with a dispersing disc 7 for the raw materials conveyed by the screw conveyor to be discharged through multiple dispersing holes 8 distributed on the dispersing disc 7.

[0035] The screw conveyor includes a conveying cylinder 6 installed and fixed to the bottom wall of the mixing base 1. A drive motor 14 is assembled and fixed to the upper surface of the conveying cylinder 6 by fastening screws. A screw conveying shaft 15 that rotates circumferentially with the bottom wall of the conveying cylinder 6 is installed and fixed at the output shaft of the drive motor 14. A screw conveying shaft 15 is assembled and fixed to the outside of the screw conveying shaft 15. Screw blades 16 are assembled and fixed to the outside of the screw conveying shaft 15.

[0036] The conveying cylinder 6 has a feed inlet 12 on the lower outer side and a discharge cylinder 13 connected to the upper outer side.

[0037] The mixed material enters the conveying cylinder 6 through the feed inlet 12. The drive motor 14 drives the auger spiral blades 16 on the spiral conveying shaft 15 to rotate, conveying the mixed material to the discharge cylinder 13 for discharge.

[0038] The screw conveyor is provided with an annular limiting groove on its exterior for the collar 9 to rotate in a circular direction. The annular limiting groove is located on the exterior of the conveying cylinder 6, which is part of the screw conveyor structure.

[0039] An assembly frame 10 for assembling and fixing the stirring motor 4 is installed and fixed on the upper surface of the opening of the stirring base 1, and a collar 9 is used to limit the rotation of the screw conveyor.

[0040] The collar 9 is connected and fixed to the stirring rod 5, and a connecting rod 11 that drives the stirring rod 5 to rotate is installed and fixed at the output shaft of the stirring motor 4. The connecting rod 11 is located outside the dispersing disk 7.

[0041] It should be added that the stirring motor 4 drives the stirring rod 5 to rotate around the outer circumference of the conveying cylinder 6 through the collar 9.

[0042] The output shaft of the stirring motor 4 is provided with a dispersing component to disperse the raw materials discharged into the dispersing disk 7.

[0043] The dispersing component includes a pair of connecting rods 17 fixed to the lower surface of the connecting rod 11.

[0046] The working principle of the above embodiments is as follows:

[0047] In use, various raw materials are poured into the mixing seat 1, and then the mixing motor 4 is started to drive the mixing rod 5 connected to the connecting rod 11 to rotate and mix the various raw materials.

[0048] During the mixing process, the drive motor 14 is activated, which drives the auger spiral blades 16 on the spiral conveyor shaft 15 to rotate. The mixture entering from the feed inlet 12 is spirally conveyed to the discharge cylinder 13 and discharged into the dispersion disc 7. At the same time, as the stirring motor 4 drives the stirring, the stirring motor 4 synchronously drives the connecting rod 17 on the connecting rod 11 to rotate, so that the dispersing plate 18 rotates synchronously along the inner cavity of the dispersion disc 7, leveling and dispersing the discharged mixture from each dispersion hole 8 and discharging it naturally into the stirring seat 1 for cyclic stirring, dispersion and falling. In this process, the fluidity of the raw materials is improved and the mixing effect of the raw materials is enhanced.
