Title: Rotor for centrifugal separator
Inventor: KONNO TATSUYA
IPC: B04B5/02
Filed: 1993-09-30
Abstract: PURPOSE:To sufficiently cool a rotor even when the temperature of a rotor chamber is higher than that of a conventional device and maintain low temperature by providing a disklike projection part on the external circumference of the rotor in the rotor for a centrifugal separator which has a hole for housing a separation sample and a cover for closing the hole. CONSTITUTION:A rotor 1 for a centrifugal separator is provided with a hole 1a for housing a separation sample and a hole 1b fitted to the rotary shaft of a driving part for rotating the rotor 1. The hole 1a for housing the sample is closed by a cover 3. A heat radiation plate 2 is fitted to the lower part of the rotor 1 as a disklike projection part and has a structure in which the outer peripheral part is made thin and stuck to the rotor 1. In such a way, the rotor does not receive restriction of high stress generated around the hole 1a for housing the sample by providing the heat radiation plate 2 in the part lower than the hole 1a of the rotor 1. The outside diameter of the heat radiation plate 2 is enlarged. The high stress part is caused by the mass of the peripheral part of the heat radiation plate 2. Therefore the stress is lowered by thinning the outer peripheral part.

Abstract: PROBLEM TO BE SOLVED: To jet out high pressure compressed air at the time of blowing away dust, etc., sticking to an object to be coated and to spray an atomized coating material with low pressure compressed air at the time of performing coating with the coating material. SOLUTION: When the pulling operation of a trigger of this gun is stopped on the halfway, an air valve passage 12 is fully opened by an air valve 16 and accordingly, high pressure compressed air is allowed to pass through an air passage 14 and jetted out from an air cap to blow away dust, etc. sticking to an object to be coated. When the pulling operation is allowed to further proceed, since a restricting part 40 of the air valve 16 enters into a valve pit 20a to restrict the air passage 12 and to reduce the opening area of the passage 12, the pressure of the compressed air drops to form low pressure compressed air and then, the low pressure compressed air is jetted out from the air cap.  Thereafter, a valve pit 21a of a coating material valve 17 is opened and a coating material supplied through a coating material passage 15 is atomized with this low pressure compressed air and sprayed on the object to be coated.
