Embodiment approach

[0051] Energy conversion mechanism: After the potential energy of the small particle material 20 under the action of gravity passes through the energy absorbing chute 4, the displacement generated by the impulse is transmitted by the long axis 3, and is converted into an elastic energy conversion device - a horizontal square balance frame. The potential energy produces a linearly scaled horizontal displacement, and the equivalent value of the horizontal displacement is transmitted to the flow detection mechanism and can be measured by the precision displacement sensor LVDT.

[0052] Flow detection mechanism: the displacement output by the energy conversion mechanism is transmitted to the precision displacement sensor (LVDT) 10 fixed by the displacement sensor holder 9 by the equivalent value of the displacement transmission bracket 11 and measured in real time. The measured displacement value is passed through A in the form of current. The / D conversion board is composed of con...

Abstract

The invention relates to a dynamic proportioning liquid after-spraying system, which uses continuous flow material fine flow controller to detect flow quantity of mass diffuse matter continuously and controls thickness of feed layer precisely after computer gets the value of instantaneous delivery. Meanwhile the invention uses microscale liquid processing unit to spray microdosage on target object. PPLA system adopts ARM build-in core technology to process both centralized telecontrol and independent control. The invention integrates fluid technology, mechanical technology, electrical control, computer soft-hardware control and so on.

Description

technical field [0001] The present invention relates to an automatic system that can evenly add a small amount of liquid to materials by spraying at room temperature——Proportionate Dosing Post Pelleting Liquid Application (PPLA) System). The system is characterized by its fully automatic dynamic working mode at room temperature, tiny spraying dosage (addition amount is less than 1 / 10,000) and accuracy (±1.5%). [0002] The PPLA system is controlled by ARM embedded core technology, which can be controlled remotely or individually. The liquid automatic post-addition technology involved in the system is a new comprehensive technical field integrating fluid technology, mechanical technology, chemical technology, electrical control, pneumatic control, hydraulic control and computer software and hardware control. Background technique [0003] The post-addition technology of liquid is a brand-new technical field. There are only a few developed countries in Europe and the United St...
