Improved air chamber and powder tank truck using the same

Abstract

The invention discloses an improved air chamber and a powder tank truck using the same. A gas inlet for introducing gas is formed in the air chamber; a gas outlet for discharging gas is also formed inthe air chamber. The air chamber is characterized in that a flow limiting plate is arranged in the air chamber, the air chamber is divided into an air inlet cavity with an air inlet and an air outletcavity with an air outlet by the flow limiting plate, and a gap for allowing an airflow to pass through and rectifying and accelerating the airflow exists on the flow limiting plate and/or between the flow limiting plate and the wall of the air chamber. The air chamber of the powder tank truck is moved upwards, and the ventilation proportion of the cloth bag is changed; an intelligent ash discharging system is additionally arranged, and the ash accumulation problem of three large ash accumulation prone parts of a traditional powder tank truck is solved.

Description

technical field [0001] The invention relates to the field of powder transportation, in particular to an improved air chamber and a powder tank truck using the improved air chamber. Background technique [0002] The powder tank truck is a special vehicle used for cement plants, cement warehouses and large-scale construction sites to transport bulk powder such as cement, stone powder, flour, chemical powder, etc. The unloading speed is its core content, which is very important for enhancing the core competitiveness of products, saving energy and reducing energy consumption. Consumption has an important impact. [0003] There are various structures of powder tank trucks nowadays, mainly divided into two types: vertical tank body and horizontal tank body, and the horizontal tank body has been widely used because of its advantages of fast unloading operation speed and high efficiency. The traditional tank car is mainly composed of air chamber, fluidized bed, intake pipe, dischar...

Problems solved by technology

Moreover, due to improper operation during the current ash unloading process, there is no booster device during the unloading process, and the valve is fully opened for unloading during unloading, resulting in low pressure in the tank; moreover, when the air compressor is constant, the fluidized bed inside The pressure is constant, which will increase the pressure difference between the inner and outer sides of the fluidized bed by ΔP. When the fluidized bed is exposed, ΔP increases, causing most of the gas to flow away from the exposed fluidized bed, and the unexposed fluidized bed Part of the gas is not enough, the material cannot be completely fluidized, and it will also cause dust accumulation

[0005] This not only increases the waste of resources, but also greatly reduces the efficiency of unloading
