Title:
POWDER COMPOUND AGENT COLLECTION DEVICE FOR SEALED PRESSURIZED-TYPE KNEADING MACHINE, AND COLLECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/073237
Kind Code:
A1
Abstract:
[Problem] To improve the work environment by preventing a large amount of a powder compound agent from being discarded as powder dust and by returning the powder compound agent into a kneading tank by capturing said powder compound agent by employing a simple means in a sealed pressurized-type kneading machine. Also to bring the compound quality closer to the design quality by drastically increasing the valuable collection rate. [Solution] A collection device (20) for collecting an ejected powder compound agent is installed on a sealed pressurized-type kneading machine for kneading a kneading material along with a powder compound agent (P) in a kneading tank (2) by rotating a kneading rotor (9). In the collection device, a tubular air bag (21) capable of expanding and contracting is connected to the side surface of the surrounding wall (4) of the kneading tank with a ventilation chute (22) between the air bag (21) and the surrounding wall (4), the surrounding wall surrounding the periphery of a pressurized lid rising/lowering path (3). A branching duct (35) capable of connecting to and being disconnected from the outside is connected to the top of the air bag, and a filter tube (25) for filtering and capturing the powder compound agent carried by a gaseous body flowing from the side of the kneading tank is disposed in a suspended manner within the air bag. As a consequence, it is possible to return the powder compound agent captured by means of the filter tube to the kneading tank by means of the pressurized air flow accumulated in the air bag.
