The problem of the suction soft connection structure of the specific gravity stone remover
The stone remover is a cleaning equipment commonly used by modern large-scale grain processing enterprises. It is mainly used to separate impurities with a larger proportion than grains such as rice and wheat. It can also be used to separate heavy impurities in other grains. The TQSX180×2 suction type specific gravity stone remover is a new type of stone remover developed on the basis of similar foreign products. It adopts suction type primary selection and blowing type multiple selection structure. There will be some grains in the stones discharged after the primary selection, and the mixture of this part of the grains and the stones will be re-selected. The re-selection sieve surface is equipped with a built-in fan to blow the air to completely separate the stones and grains. After the stones are concentrated, they are discharged from the stone discharge port. This compound fish scale hole sieve stone remover has the characteristics of compact structure, stable operation, large output, good stone removing effect, simple, convenient and fast maintenance. It is currently the most popular stone remover used by domestic rice milling enterprises. The majority of users are welcome and gradually sold to Southeast Asia. However, there are still some shortcomings in the structure of this model of stone removing machine. The soft suction connection connecting the cover and the suction device is easy to deform and break, which leads to air leakage in the suction duct and unstable air volume and pressure in the machine, which directly affects the stone removal. The effect must be replaced in time. With this structure, the soft connection has a short service life, which greatly increases maintenance costs and labor intensity of workers, and reduces production efficiency.
