摘要： PROBLEM TO BE SOLVED: To enable to easily remove a dust clogged in a nozzle main body. SOLUTION: A water passing hole 5 toward the shaft direction, opened on a base end surface, is formed in a nozzle main body 1 and also a guide hole 5 communicated with the water passing hole 2 is opened at the tip of the nozzle main body 1. A water spraying hole 6 positioned at the base end side apart from the tip of the water passing hole 2 and having the height and notching depth is accordance with a water spraying quantity and a water spraying angle, is formed in the nozzle main body 1. A piston 7 having a size enabling to arrange at a tip side apart from the position of the water spraying hole in the water passing hole 2 of the nozzle main body 1 is inserted freely slidably. A piston rod 8 connected with the piston 7 is led out of the guide hole 5 of the nozzle main body 1 and an operation knob 10 is provided on the tip of this piston rod 8.

摘要： PROBLEM TO BE SOLVED: To rotate a rotary dust remover by reation of water jetted from a jet nozzle so as to eliminate the need of a drive transmitting mechanism and facilitate maintenance and inspection. SOLUTION: A dust removing apparatus includes a rotary dust remover 1 formed substantially cylindrical, wherein one end surface of the remover is opened and a water permeable screen 3 is stretched on the other end surface. The rotary dust remover 1 is rotatably supported by a shaft in a position for partitioning a channel 7 with the substantially lower half part of the rotary dust remover 1 faced below the surface of the water. Jet nozzles 6 having jet orifices directed in the opposite direction to the rotating direction of the rotary dust remover 1 are provided at fixed intervals on the peripheral surface of the rotary dust remover 1. Each jet nozzle 6 is provided with a distributing means 13 for distributing water. The distributing means 13 is adapted to distribute water to the respective jet nozzles 6 positioned in the water with the rotation of the rotary just remover 1. The distributing means 13 comprises a distributing hole 15 opened in the outer peripheral surface in such a manner as to be communicated with a water passing hole 14 in the central part of a fixed shaft 12 inserted in a bearing unit 10 of the rotary dust remover 1 and distributed holes 16 formed corresponding to the respective jet nozzles 16 of the bearing unit 10.
