Product Details

The drum sand shaker is mainly used in the foundry industry. After the casting is formed, the sticky sand can be recycled. The drum sand cleaner replaces manual sand cleaning, which greatly improves the production efficiency of the foundry industry. The drum sand shaker mainly includes the drum body, For parts such as single-pass sand-out section, shatter-out section cover, support frame, transmission mechanism, spiral guide plate, feed port and casting exit, the ratio of casting to sand fed to the feed port is usually above 13, so there are A large amount of loose sand and sand clusters roll in the drum body along with the castings. There are very few collisions between the castings and the castings, and the castings and the inner wall of the drum. This affects the impact of sand falling from the surface of the castings, and there are few chances for the castings to collide with large sand clusters. , It is not conducive to the collapse of large sand clusters, the effect of falling sand is poor, and there is still more old sand coming out with the casting at the exit of the casting.

Drum shakeout machine uses vibration and impact to separate the sand from the casting in the casting mold. The vibration source of the sand shaker is divided into three categories: mechanical, electromagnetic and pneumatic. The mechanical inertia sand shaker is widely used. The structural characteristics of the inertial sand shaker are: the sand shaker bed is equipped with a heavy rotating shaft. When the shaft rotates, the heavier centrifugal force (exciting force) is generated to make the shaker bed mounted on the support spring vibrate. This vibration It is a motion superimposed by free vibration and forced vibration, and the magnitude of the load can change the amplitude. If the load is too large, the amplitude will decrease sharply, and the sand falling efficiency will be reduced; if the load is too small, the vibration will be too large, which will damage the flask and equipment. Therefore, a fixed bracket should be installed on this type of sand shaker to form an inertial impact sand shaker. When the sand falls, the mold is placed on the support, leaving a gap between the bottom surface of the mold and the sand falling grid bed, and the bottom surface of the mold is impacted by the vibration of the grid bed to separate the casting from the sand. Since the mold is not directly placed on the shakeout grid bed, the influence of the change of the mold weight on the amplitude of the shakeout machine is relatively reduced. For small and medium-sized castings without a box mold, a drum-type sand shaker can also be used, which is generally installed on a boxless molding production line for small and medium-sized castings. In addition to falling sand, it also has hot sand cooling, old sand screening, and sound insulation. Heat insulation and dust removal.
