Abstract

PURPOSE:To efficiently wash a heat transfer pipe without using specific driving motive power and a bearing by rotating an injection nozzle for washing in such a state that it is pushed up with water pressure and also aligning the end part opposite to the turning blade of the nozzle with water seal. CONSTITUTION:The fluid sent at about 7-8kg from a conveying pump is introduced into a turning blade housing chamber 3 in the lower part of a nozzle through a supply pipe 4 and gives rotating force to a turning blade 2, and force for pushing up the nozzle is added to a shaft 14; thereby, the nozzle is brought into contact with a bearing metal 29. On the other hand, one part of the fluid is introduced into a cover chamber 8 via a flow rate control part 9 from a flow path 7 and sent into the injection nozzle 6 through a fluid inlet 17 and injected through an injection port 16a. At this time, one part of the fluid is jetted through a fluid discharge port 21 of the center of a closed pipe 22 and fed to a bag-shaped bearing chamber 20. As a result, the seal due to the fluid is caused between the chamber 20 and the closed pipe 22 and the injection nozzle pipe 16 is aligned.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to obtain a cleaning injection nozzle which is the smallest nozzle even when a plurality of heat exchanger tubes are arranged and can constantly rotate its blades. The technical means of the present invention to solve this technical problem is that one end of the injection nozzle tube is provided with a swirl vane that rotates with the fluid supplied to the injection nozzle tube, and the other end is a closed tube with a fluid outlet. The bag-shaped bearing part supporting the bag-shaped bearing part and the nozzle pipe end thereof are sealed and aligned with fluid supplied from the fluid supply chamber on the swirl vane side through the fluid discharge port. The cleaning spray nozzle is characterized by:
