Claims

[Scope of Claim for Utility Model Registration] (1) A cage-shaped or plate-shaped scraper is placed inside a powder or granule transfer channel for transferring powder or granules such as coal along the inner wall surface of the channel in the direction of powder or granule transfer. By reciprocating the scraper continuously or intermittently by a fluid pressure cylinder installed outside the powder transfer channel, the powder and granules are removed in the flow channel. A crosslinking prevention device during transport of powder or granular material, characterized in that it prevents crosslinking from occurring. (2) A vertically arranged coal chute in which the granular material transfer channel supplies measured coal to a pulverizer;
A cage-shaped scraper is installed inside the lower chute located on the call feeder side of this coal chute so that it can move up and down along the inner wall surface of the chute, and a flat plate and a seal box are fixed on both sides of the outside of the lower chute, and the flat plate and the lower Slit-shaped vertical holes are formed on both sides of the cylinder wall of the chute;
A scraper having a movable arm inserted through the vertical hole is configured to be moved up and down continuously or intermittently by left and right hydraulic cylinders, and is in contact with a flat plate sliding surface inside the seal box. A seal plate with a movable arm for closing a vertical hole, and a seal holder adjacent to the seal plate and fixed to the arm are provided, and a biasing means for bringing the seal plate into close contact with the sliding surface of the flat plate is assembled in the seal holder. The device for preventing crosslinking during transfer of powder or granular material according to claim 1, characterized in that: (3) A plunger in which the biasing means is built into the seal holder so that it can move in and out toward the seal plate, a set screw that is screwed into the plunger-incorporated portion of the seal holder, and a space between the set screw and the plunger. 3. The prevention of crosslinking during transfer of powder and granular material according to claim 2, further comprising a spring interposed therein which presses the end face of the plunger to the seal plate and brings the seal plate into close contact with the sliding surface of the flat plate. Device.
