Description

Technical Field

[0001] The utility model relates to the technical field of bulk material transportation, in particular to a filling system for a tank truck or a special container for powder and granular materials. Background Art

[0002] Currently, large sealed containers, such as tank containers, are highly favored for transporting powdered and granular materials due to their advantages of saving packaging costs, being safe and reliable, and being easy to load and unload. Existing patents, such as CN2116183Y, disclose a pneumatic conveying device for powdered and granular materials and a tank container, which achieve the transportation of powdered and granular materials through a sealed container with several funnels and a set of pipelines. Most of the improvements in the existing technology are designed for the transportation of powdered and granular materials. Currently, the filling of powdered and granular materials is carried out using a ton-packing machine. Since the container has only one inlet and outlet, the overall filling efficiency is low, and the filling process requires timely manual observation to prevent the filling from exceeding the preset limit. Utility Model Content

[0003] In response to the above technical problems, a filling system for powder and granular materials using a tank truck or a special container is provided. The technical means adopted by the utility model are as follows:

[0004] A filling system for a tank truck or special container for powder and granular materials comprises an external support structure, a buffer silo and a docking hopper. The top of the tank truck or special container for powder and granular materials to be filled is provided with a plurality of feed ports, the tank truck or special container for powder and granular materials to be filled is docked in the external support structure, the buffer silo is arranged above the external support structure, the input end of the buffer silo is connected to the material storage silo, and the output end of the buffer silo is connected to the docking hopper. The number of the docking hoppers is a plurality or more of the feed ports provided on the tank truck or special container for powder and granular materials to be filled.

[0005] Furthermore, the external support structure includes a support column and a support plate, the support column is upright on the ground, and the support plate is horizontally installed above the support column.

[0006] Furthermore, the buffer silo and the storage silo are connected via a feed air duct, and the material is transported to the buffer silo via an air feeding system.

[0007] Furthermore, a gas-solid separator is provided on the top of the cache silo, and a material level monitoring mechanism is provided on the side of the cache silo.

[0008] Furthermore, the docking hopper is a vibrating hopper, which is used to activate the material through vibration.

[0009] Furthermore, a retractable feed pipe is provided at the bottom of the docking hopper, and the output end of the feed pipe is connected to the feed port of a tank truck or a special container for the powder and granular materials to be filled.

[0010] Furthermore, a weighing sensor is provided at the bottom of the cache silo.

[0011] The utility model has the following advantages: the utility model completes the feeding of powder and granular materials from the storage silo to the powder and granular material tank truck or special container by vertical filling. Compared with the traditional container end face feeding method, the utility model completes the filling of materials through multiple docking hoppers, and the loading speed is faster. In addition, the uniformly distributed unloading device also prevents the material from forming accumulation like traditional filling, and the filling utilization rate is higher. By setting a vibrating hopper, the arching, clogging and sticking of the material can be effectively eliminated, and the problem of difficult silo discharge can be solved. By setting material level monitoring, weight monitoring and other methods, the material filling process can be effectively monitored, reducing the labor intensity of the staff.
