Internal cleaning apparatus
First Claim
1. An internal cleaning apparatus comprising:
- a rotary shaft having a liquid flow passage and being axially rotatable;
a revolving rotary shaft having a liquid flow passage connected to the liquid flow passage of the rotary shaft, being provided in a direction substantially perpendicular to the rotary shaft, and being revolvable about the rotary shaft and axially rotatable;
a nozzle being provided at a leading end of the revolving rotary shaft for ejecting a liquid, which is supplied from the liquid flow passage of the revolving rotary shaft, while revolving around the revolving rotary shaft; and
a gas flow passage being provided along the liquid flow passage of each of the rotary shaft and the revolving rotary shaft from a gas inflow opening provided in the rotary shaft,wherein the nozzle comprises a smooth nozzle which is flattened in a direction parallel to the revolving rotary shaft, and nozzle comprising;
an ejection tip being provided at a tip of the liquid flow passage for ejecting the liquid; and
a communication path communicating with the gas flow passage, andwherein a gas-liquid mixture flow, having a gas supplied from outside an object to be cleaned mixed with the liquid ejected from the ejection tip in the nozzle, is ejected from the nozzle.
