Description

Technical Field

[0001] This utility model relates to the technical field of refractory bricks, and in particular to a silicon carbide homogenizing mixer for refractory bricks. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. Alumina-zirconium silicon carbide bricks are a type of composite refractory brick, different from ordinary refractory bricks, and require mixing and stirring during production. Existing technology publication number CN214051241U discloses a refractory brick uniform mixing device, including a mounting frame, a stirring mechanism, a fixing frame, and a discharge port. Support feet are fixed at both ends of the bottom of the mounting frame, and a feed port is opened at the top of the main body. The stirring mechanism for mixing refractory brick materials is installed inside the main body. The stirring mechanism includes a driving rod, a main blade, a crossbar, a driven rod, a gear, and a secondary blade. The driving rod is bearing-connected to the mounting frame, and its bottom is connected to a rotating shaft. A crossbar is fixed to the top of the driving rod, and driven rods are bearing-connected to both ends of the crossbar. However, during stirring, a small amount of silicon carbide products often adheres to the inner wall, which existing silicon carbide product mixing mixers cannot clean, thus failing to completely mix the materials. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a silicon carbide homogenizing mixer for refractory bricks that can clean up adhering materials and improve the mixing quality.

[0004] This utility model discloses a silicon carbide homogenizing mixer for refractory bricks, comprising a mixing drum, a support ring, multiple legs, a grinding assembly, a stirring mechanism, a cleaning assembly, and a screening assembly. A support ring is fixedly installed in the middle of the outer wall of the mixing drum.

[0005] Preferably, the grinding assembly includes a grinding cylinder, a feeding hopper, a grinding roller, an arc-shaped support, a drive motor, and a drive shaft. The grinding cylinder is installed on top of the mixing tank. The feeding hopper is connected to the top input end of the grinding cylinder. An arc-shaped support is connected to the upper part of the feeding hopper. A drive motor is fixedly installed at the top center of the arc-shaped support. The output end of the drive motor passes through the bottom of the arc-shaped support and is connected to the drive shaft. The grinding roller is connected to the bottom of the drive shaft. The grinding roller is located inside the grinding cylinder. Matching grinding grooves and crushing teeth are provided on the inner wall of the grinding cylinder and the outer wall of the grinding roller. The material is added to the feeding hopper, and the drive motor is started to drive the grinding roller to rotate through the drive shaft, so that the material enters between the grinding cylinder and the grinding roller, and the material is crushed and sheared. The crushed material enters the mixing tank.

[0006] Preferably, the mixing mechanism includes a mixing motor, a mixing shaft, multiple C-shaped mixing frames, multiple agitator plates, and multiple pusher blades. The bottom of the mixing tank is conical, and multiple discharge ports are axially opened at the bottom of the mixing tank.
