Claims

[Claims for Utility Model Registration] (1) A collection device 1 comprising a collector 10 connected to a transport pipe 42 for pneumatic transport of powder and granules, and a charge hopper 20 at the bottom of the collector 10, comprising: The collector 10 and the charge hopper 20 are connected through a valve seat 30, and a communication port 38 between the collector 10 and the charge hopper 20 is formed in the valve seat 30. The moving member 50 includes a valve body 5
5, and the valve body 55 is separated from or seated on the valve seat 30 by vertically moving the vertically moving member 50, and the communication port 38 of the valve seat 30 is opened and closed. . (2) A fluid pressure cylinder is employed as the vertically movable member 50 and is provided above the collector 10, and a valve body 55 is provided at the tip of the piston rod 52 of the fluid pressure cylinder 50. Collection device. (3) The collection device according to claim (1) or (2), wherein the valve body 55 is detachably installed on the piston rod 52 of the fluid pressure cylinder. (4) The collection device according to any one of claims (1) to (3), wherein the valve body 55 and the valve seat 30 are made of the same material as the powder to be pneumatically transported. (5) The valve seat 30 has compressed gas supply holes 60, 6 that open into the collector 10 or the charge hopper 20.
0a and this compressed gas supply hole 6
0 and 60a are connected to a gas supply source 61, and the compressed gas is injected from the compressed gas supply holes 60 and 60a onto the outer surface of the valve body 55. Collection device according to any of paragraph 4). (6) Either or both of the collector 10 and the charge hopper 20 are provided with gas supply pipes 72 and 73 for supplying gas for cleaning the inside of the collection device 1, and gas is supplied from the gas supply pipes 72 and 73. 5. The collection device according to claim 1, wherein the collected gas is discharged from an exhaust hole 44 provided in the collector lid 40. (7) Any one of claims (1) to (6), wherein the transport pipe 42 is of a small diameter and has an inner diameter that is 2 to 6 times the maximum diameter of the particles of the powder or granular material to be transported. The collection device described in Crab.
