Description

Technical Field

[0001] The utility model relates to the technical field of mixing and grinding machines, in particular to a mixing and grinding machine for processing magnesia carbon bricks. Background Art

[0002] As a composite refractory material, magnesia carbon brick has many advantages such as high temperature resistance and corrosion resistance. It is mainly used for the lining of converters, AC arc furnaces, DC arc furnaces, slag lines of ladles and other parts. In order to effectively reduce production costs and improve competitiveness, the recycling industry of waste magnesia carbon bricks and other refractory materials has developed rapidly. Recycled magnesia carbon bricks are made of used furnace lining magnesia carbon bricks as raw materials. They are pressed after a series of processes such as crushing, iron removal, screening and baking. Usually, part of the recycled magnesia carbon bricks are used as aggregates, with appropriate amounts of carbon refractory materials and other refractory powders. The products are pressed by mixing with carbon binders. The performance is significantly improved and the service life can be extended. Add appropriate amounts of carbon refractory materials and other refractory powders to the recycled magnesia carbon bricks, and mix and grind them with a mixer to ensure uniform mixing.

[0003] Publication No. CN216856857U discloses a mixing and grinding machine for processing magnesium carbon bricks, including a mixing and grinding barrel, a first motor is fixedly connected to the lower surface of the mixing and grinding barrel, a first rotating shaft is fixedly connected to the output shaft of the first motor, a scraper is fixedly connected to the outer surface of the first rotating shaft, a second rotating shaft is rotatably connected to the outer surface of the first rotating shaft through a first fixed block, a rolling roller is fixedly connected to the outer surface of the second rotating shaft, a crushing roller is fixedly connected to the outer surface of the second rotating shaft, a third rotating shaft is rotatably connected to the outer surface of the first rotating shaft through a second fixed block, and the upper surface of the supporting bottom plate is fixedly connected to the outer surface of the second rotating shaft. A support column is connected, one end of the support column is fixedly connected to a cross bar, the lower surface of the cross bar is fixedly connected to an electric telescopic rod, one end of the electric telescopic rod is fixedly connected to a mounting plate, the upper surface of the mounting plate is fixedly connected to a second motor, the output shaft of the second motor is fixedly connected to a telescopic sleeve, the inner side wall of the telescopic sleeve is slidably connected to the telescopic rod, the outer surface of the telescopic sleeve is fixedly connected to a third fixed block, the outer surface of the third fixed block is rotatably connected to a first connecting rod, one end of the first connecting rod is rotatably connected to a cleaning plate, and one end of the telescopic rod is fixedly connected to a fourth fixed block. Although this type of mixer and grinder scrapes the agglomerated powder from the inner bottom wall of the mixing and grinding barrel through a scraper, the block material can be crushed through the rolling action of the crushing roller, thereby making the rolling effect of the rolling roller better. However, there is a problem of uneven material flow, which is easy to cause excessive accumulation of materials in certain areas of the mixing and grinding barrel, which may cause blockage or obstruction during the rolling process.
