Description

Connection device for bulk powder discharge

technical field

The utility model relates to the field of loose powder unloading, in particular to a connection device used for loose powder unloading.

Background technique

In the traditional starch transportation method, upstream starch companies generally supply starch to downstream starch companies by packaging starch into one ton/bag. This transportation method requires a lot of human resources when loading and unloading starch bags.

In order to facilitate transportation and improve the efficiency of starch loading and unloading, new starch transportation methods have been developed in recent years. In the new starch transportation method, the upstream starch enterprise only needs to pour the starch into the container with the inner bag, and the container reaches the downstream starch enterprise through circulation, and then the downstream starch enterprise uses the unloading mechanism to store the starch in the container into the starch silo.

The existing discharge mechanism includes a discharge connection device and a star discharger. The star discharger is provided with a soft connection pipe, and the discharge connection device can drive the soft connection pipe to move to the discharge port of the lined bag. The worker then seals the connection between the flexible connecting pipe and the discharge port of the liner bag. However, when the existing unloading connecting device is unloading, in order to avoid the interference between the unloading connecting device and the container, the container cannot be tilted too much, so that the starch in the lining bag can only pass through the star-shaped unloader. The negative pressure is pumped into the star discharger, which causes problems such as long discharge time and high energy consumption.
