An improved air chamber and a powder tank truck using the improved air chamber

Abstract

The invention discloses an improved air chamber and a powder tank truck using the improved air chamber. The air chamber is provided with an air inlet for introducing gas, and the air chamber is also provided with an air outlet for discharging gas. It is characterized in that a restrictor plate is set in the air chamber, and the restrictor plate divides the air chamber into an air inlet chamber with an air inlet and an air outlet chamber with an air outlet, and the restrictor plate and / or Or there is a gap between the restrictor plate and the wall of the air chamber for the airflow to pass and to accelerate the rectification of the airflow. The invention solves the problem of dust accumulation in the three major dust-accumulating parts of the traditional powder tank truck by moving the air chamber of the powder tank truck upward, changing the ventilation ratio of the cloth bag, and adding an intelligent ash unloading system.

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...

AI Technical Summary

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
