Background
With the rapid development of urban construction, the construction of a large number of high-rise buildings and high-rise buildings makes the pile foundation widely applied. Among them, the prestressed concrete pipe piles are used in large quantities because of their high construction speed, good prefabrication quality and relatively low construction cost, and the production of prestressed concrete pipe piles is increased year by year. The production process of the tubular pile comprises the following steps: mixing, material distribution and pouring → tensioning → centrifugal forming. During the high-speed centrifugal forming process, a large amount of strongly alkaline redundant turbid liquid, namely tubular pile residual slurry, is generated on the inner wall of the tubular pile. Because the treatment cost of the residual slurry is high, the residual slurry is poured into a container by general enterprises, is manually crushed after being condensed and hardened, and is transported to a refuse landfill for landfill, thereby causing secondary pollution. Pipe pile manufacturers are numerous, the production amount of residual slurry is large, and pollution caused by the residual slurry is increasingly troubling pipe pile manufacturers. On the other hand, along with the popularization and application of concrete bricks, the number and the yield of concrete brick production enterprises are continuously increased, the competition is intensified, and the production cost of the concrete bricks is increased due to the rising price of raw materials such as cement, stone chips and the like. In order to reduce the production cost, some enterprises aim at the pipe pile industry with eyes and utilize the rest of slurry to produce the concrete-coated bricks. The manager enterprises generally provide the residual slurry for free or at low price, and the concrete brick production enterprises can use the residual slurry to partially or completely replace cement to produce concrete bricks, so that the production cost can be reduced, and the market competitiveness of the enterprises can be enhanced.
In the preparation process of concrete brick, the batching is its an important process, before production, need add other raw materialss in the surplus thick liquid of tubular pile, carry out intensive mixing and make it even to form the better concrete brick of texture and make raw materials, traditional agitated vessel structure is coarse, and stirring effect is unsatisfactory, influences the quality of later stage concrete brick. Moreover, the traditional stirring machine cannot contact the raw materials on the side wall, so a hard layer can be formed after a long time, and the stirring quality of the internal raw materials is influenced.
