Abstract

PURPOSE:To remove foreign substance jammed in a space between a casing and the tip of a vane, by making the casing capable of forward or backward free motion by means of a driving device, in case of a rotary valve. CONSTITUTION:In case a foreign substance is mixed in powdery granules and jammed in a space between the inner surface of a case 7 and the tip of a vane 17, driving torque in a rotor 16 grows large. When this torque enlargement is detected by an overload detector (unillustrated), a selector solenoid valve (unillustrated) of an air cylinder 11 operates and therefore a mobile casing 6 comes into a state of opening. Under this condition, the foreign substance is transferred to a discharge port 3 passing through an empty space 21. After the lapse of the setting time from what the mobile casing 6 is in a state of opening, again the selector solenoid valve operates whereby the mobile casing 6 returns to the closing state as usual.

16 and blades 17 have the same structure and function as in the previous embodiment, and the rotor 16 rotates in the direction of the arrow to transfer the powder from the upper part to the lower part. However, the side of the casing 1 that guides the powder or granular material is a box 21 with a sealed structure that expands outward, and a movable casing 22 is provided at a position that separates the box 21 and the blades 17. In other words, the side of the casing 1 that does not transfer the powder and the moving casing 2
2 forms a cylindrical casing surrounding the rotor 16. A hydraulic cylinder 23 is fixed to the box 20, and the iron 24 of this hydraulic cylinder 23 is
It is connected to a protrusion 25 on the movable casing 22 side, and the movable casing 22 moves forward and backward by the operation of the hydraulic cylinder 23.

At this time, the wheels 25 attached to the lower part of the moving casing 22
moves on rails 27 provided in the box 20 to guide the movable casing 22. 28 is an elastic sealing member that maintains airtightness between the casing 1 and the movable goose song 22. Similarly, a gasket 29 is attached to the outer periphery of the movable casing to maintain airtightness with the casing 1. In addition, a stopper 3 of a hexagonal bolt is installed at a suitable location around the outer periphery of the moving casing.
0 is attached to the inner surface of the moving casing 22 and the blade 1.
It plays the role of keeping the gap at the tip of 7 appropriate. According to this embodiment, since the movable casing 22 is moved forward and backward via the wheels 26, the movement resistance is small and the hydraulic cylinder can be made compact. Further, since the stopper 30 is provided, contact trouble between the movable casing 22 and the blade 17 can be avoided.
