Abstract:
PROBLEM TO BE SOLVED: To provide a powder feeding device capable of equally dispersing and feeding powder while suppressing destruction of particles constituting the powder, and an electrode manufacturing apparatus comprising the powder feeding device.SOLUTION: A powder feeding device 2 comprises: a case 6 in which a storage part 6a is formed for temporarily storing powder 10 and which includes a feeding port 6b formed on an upper end of the storage part 6a and a rectangular discharging port 6c formed on a lower end of the storage part 6a; a rotor 7 which is disposed within the case 6 and rotated to transfer the powder 10 in the storage part 6a to the discharging port 6c; and a mesh body 8 through which the powder 10 transferred to the discharging port 6c is passed. The powder feeding device 2 is configured to feed the powder 10 while dropping it from the discharging port 6c onto a top face of an electrode foil 5 which is horizontally displaced perpendicularly below the discharging port 6c. The rotor 7 has a brush shape including a plurality of bristle members 7b, 7b, ... substantially radially planted towards the outside in a radial direction around an axial center G of the rotor 7.
Abstract:
PROBLEM TO BE SOLVED: To provide a composite structure forming method, prepared particles, and a composite structure forming system in which the concentration of micro particles in the aerosol can be better stabilized, and a stable state can be maintained over a long time. SOLUTION: The composite structure forming method is based on an aerosol deposition method, wherein an aerosol prepared by dispersing micro particles of a brittle material in a gas is sprayed toward a base material to form a structure made of the constituent material of the brittle material micro particles on the base material. This method is characterized by the following facts: a plurality of prepared particles that are aggregates prepared by fixing a plurality of particles that comprise the brittle material micro particles are held in a holding mechanism; the prepared particles are supplied from the holding mechanism into an aerosol forming mechanism; the supplied prepared particles are broken apart in the aerosol forming mechanism to form aerosol; the aerosol is sprayed toward the base material to form a composite structure of the structure and the base material.

Abstract:
1493637 Electrostatic spray booth GEMA AG APPARATEBAU 12 Nov 1975 [14 Nov 1974 23 July 1975] 46791/75 Heading B2L In an electrostatic spray booth 10 of the type wherein excess powder from a spray gun 17 is removed therefrom through a moving filter strip 23 by suction of a blower 34, the filtered powder is removed from the upper run 22 of the strip outside the booth by a suction nozzle 44, the removed powder then being drawn by suction blower 49 via line 47 through a cyclone separator 48 wherein most of the powder removed from the air stream and passed via sieve 54 to supply container 19. Powder not separated at 48 is recycled to the booth via line 58 and discharge tube 59. Fresh powder is added to the system from container 41 onto filter strip 23 upstream of the suction nozzle 44 and downstream of corona discharge electrode 37. The suction nozzle 44 may be provided with a device illustrated in Figs. 2 and 3 (not shown) for pulsating the air in suction duct 47 so as to prevent powder deposition therein. The suction blower 49 is preferably of the injector type [Fig. 4 (not shown)] and comprises two parts (71), (72) defining an annular gap (76) therebetween through which compressed air is blown into a constriction (82) thereby drawing-in air from line 50.
