Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to a material bucket anti-segregation device. Background Technology

[0002] The shaped refractory materials are produced using an automatic weighing machine and an automatic forming press. The mixed and rolled refractory clay is added from the upper hopper, while the lower part is an automatic feeding device that supplies material according to the forming requirements. During use, severe clay segregation occurs, significantly impacting the quality of the finished product. Analysis revealed that when feeding from the top of the hopper, the semi-dry clay falls freely, forming a cone-shaped pile with coarse particles rolling to the outer edge, resulting in uneven particle size. During discharge, the cone-shaped structure of the hopper and the tendency for the clay to arch inside cause the finer clay in the middle to be discharged first. Even adding a vibration device to the hopper did not improve the overall clay segregation. Patent No. CN204469614U discloses an anti-segregation stirring system, comprising a storage tank, a storage tank cover, a speed-regulating reducer mounted on the storage tank cover, a stirring shaft extending into the storage tank and fixedly connected to the output shaft of the speed-regulating reducer, stirring blades fixedly connected to the stirring shaft, a discharge port at the bottom of the storage tank, and a discharge valve on the discharge port. The stirring blades are evenly spaced along the stirring shaft, and no two stirring blades are on the same horizontal plane; the angle between the projections of two adjacent stirring blades on the horizontal plane is 120°; the angle between the upper plane of the stirring blade and the horizontal plane is acute; and the angle between the centerline of the stirring blade and the centerline of the stirring shaft is 45°. This invention forcibly intervenes in the downward flow process of the mixed powder, ensuring thorough mixing and solving the segregation problem during the falling process. The mixed powder is added to the storage tank 1 by opening the top cover 7 of the storage tank. After it is full, the speed reducer 2 is started. At this time, the material in the storage tank has formed a cone shape. Larger particles roll to the edge of the cone. Since the stirring blade is tilted downward, the larger particles on the outside cannot be fully mixed during stirring, and segregation will still occur. Therefore, this utility model proposes a material tank anti-segregation device. Utility Model Content

[0003] The main purpose of this utility model is to provide a material bucket anti-segregation device. The stirring assembly can destroy the conical structure of the material pile. The first stirring blade and the second stirring blade are inclined in opposite directions. During the rotation, they can push the materials on the inner and outer sides to mix fully and prevent segregation.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a material barrel anti-segregation device, comprising a material barrel, a main shaft vertically and rotatably mounted inside the material barrel, the main shaft being connected to a drive mechanism, and stirring assemblies provided at both the bottom and top of the main shaft, the stirring assembly including a bushing fixed on the main shaft, the bushing having four mounting holes evenly distributed at angles, a first stirring rod and a second stirring rod respectively mounted in two opposite pairs of mounting holes, the ends of the first stirring rod and the second stirring rod being respectively connected to a first stirring blade and a second stirring blade, the right-side angle formed by the first stirring blade and the first stirring rod being an obtuse angle, the left-side angle formed by the second stirring blade and the second stirring rod being an obtuse angle, and the drive mechanism being located outside the material barrel.

[0005] Preferably, the driving mechanism includes a drive shaft that extends horizontally into the storage bin, one end of the drive shaft is connected to a drive motor via a reduction gearbox, a transmission box is provided inside the storage bin, the main shaft passes through the transmission box, and the other end of the drive shaft passes through the transmission box and is connected to the main shaft via a bevel gear set.

[0006] Preferably, sealing rings are provided at the connection points between the main shaft and the drive shaft and the transmission box.

[0007] Preferably, the length of the second stirring rod is less than the length of the first stirring rod, and the length of the second stirring blade is less than the length of the first stirring blade.

[0008] The beneficial effects of this utility model are as follows: the right-side angle formed by the first stirring blade and the first stirring rod is an obtuse angle, and the left-side angle formed by the second stirring blade and the second stirring rod is an obtuse angle. When the drive motor drives the main shaft to rotate, the second stirring blade flips the inner material outward, and the first stirring blade flips the outer material inward, thereby fully mixing the materials and preventing segregation. The drive motor and the reduction gearbox are located on one side of the storage tank, which, compared with the prior art where they are located on the top of the storage tank, provides a larger top space and is more conducive to feeding.
