The basic composition and function of concrete mixer
A concrete mixer is a machine that mixes cement, sand aggregate and water and mixes them into a concrete mix. It mainly consists of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and support device. According to the nature of work, it is divided into batch type (batch type) and continuous type; it is divided into self-falling type and forced type according to the stirring principle; fixed type and mobile type according to installation method; tilting type and non-tilting type according to discharging method; According to the structure of the mixing tube, it is divided into pear type, drum type, double cone, disc vertical axis type and round groove horizontal axis type. The mixer produced by Zhengzhou Wode is generally called a mixing station. It is generally composed of a grouting station and a mixing station, which can maintain continuous and uniform mixing and slurrying. It has a unique advantage in application.
The concrete mixing station produced by Zhengzhou Wode is mostly a vertical mixing station and a forced mixing station. The forced concrete mixing station comprises a mixing drum, and the stirring drum is provided with a stirring shaft. The stirring shaft on both end walls of the mixing drum is equipped with a side arm for cleaning the end wall surface, and a midpoint on the stirring shaft between the two arms A pair of spirally arranged stirring arms are mounted on each side of the two sides. The two sets of stirring arms are arranged from the end arm to the middle arm in the axial arrangement, and the arrangement in the rotating direction is evenly distributed in the end arm to the middle arm, each The top end of the stirring arm has a fixed stirring blade, and the arms of the two arms lag behind the end arms of the stirring arm on the same side in the rotation direction.
The mixing arm itself is further divided into a side mixing arm (with positive and negative points), and the middle mixing arm (also has positive and negative points) can realize forward rotation and reverse rotation. Accelerate the agitation of the concrete.
Concrete mixing plants are mainly used in civil construction projects, such as construction sites, dam construction and slope support, soil compaction, rock grouting. Sometimes offshore construction projects require the addition of concrete mixing stations. The application of concrete mixing plants has saved a lot of manpower and material resources and is therefore widely welcomed.
Concrete mixers should be cleaned regularly or irregularly to maintain their superior performance. Then, when cleaning up, you should pay attention to the following aspects. Before starting the concrete mixer, check whether the controllers are good. After the work stops, pour water and stones into the mixing drum for 10~15 minutes to clean, then remove the water and stones. If the operator has to enter the mixing drum for cleaning, in addition to cutting off the power supply and removing the fuse, the switch box must be locked. Regular maintenance and maintenance of the items specified in the maintenance procedures, such as cleaning, lubrication, and refueling. It is forbidden to use the method of hammering to remove the concrete accumulated in the concrete mixer cylinder during cleaning. It can only be removed with a chisel. In the cold season, after the work is finished, the mixer roller is used to clean the water in the water pump, the water tank and the water pipe to prevent the water pump, the water tank and the water pipe from freezing. At present, the concrete mixer/stand where you need to pay attention is this. I hope I can give you some help.
