The invention discloses an automatic tank bottom blowdown
system. The
system comprises a tank inside
dirt suction device and a tank outside blowdown device which are connected with each other through a blowdown
pipe, wherein the tank inside
dirt suction device drives a turntable by a drive mechanism, a plurality of
dirt suction pipes are distributed on the turntable, and the turntable and the dirt suction pipes rotate with a hollow stand column as a center of circle. By virtue of strong negative-pressure attraction generated by a dirt suction pump of the tank outside blowdown device, dirt is sucked into the dirt suction pipes, then transported into a column sleeve type collection cavity to be gathered, and finally discharged from the tank outside blowdown device through the blowdown
pipe, thereby automatically discharging dirt at the bottom of a tank, avoiding inconvenience of manual cleaning in a traditional way, shortening shutdown time, improving production efficiency, lowering production cost greatly, saving manpower and
material resources as well as financial resources, and avoiding potential safety
hazard caused by manual cleaning. The automatic tank bottom blowdown
system is safe and reliable, is reasonable in structure, convenient to operate and high in
automation degree, facilitates recycling and retreatment of dirt, and avoids environment
pollution likely to be caused by manual cleaning.
