摘要:
There is disclosed an electrostatic separation and classification apparatus (20) which includes a pair of electrode unit mechanisms (21, 22) having spaced electrodes (28, 29), insulative endless belts (30, 31) covering opposite surfaces of the electrodes (28, 29) and opposed to each other for feeding in circulation, and deposit scratching members (38, 39) remote from a position in which an electrostatic field produced between the electrodes (28, 29) works and in contact with outer surfaces of the endless belts (30, 31) throughout their width, respectively, thereby increasing the rate of operation and safety.
摘要:
An electrostatic separator is obtained that can improve the efficiency of separating material fragments contained in a mixture. The electrostatic separator includes a transfer unit (130) and a counter electrode (180). The transfer unit (130) transfers a mixture (100) electrically charged, which is a target fed into an electrostatic field space to be separated according to a state of electrical charging. The transfer unit (130) includes an end portion (1) in a direction of transfer of the mixture (100). The counter electrode (180) faces the end portion (1). The counter electrode (180) can form an electric field between the end portion (1) and the counter electrode (180) upon application of a voltage. A first surface portion of the counter electrode (180) facing the end portion (1) has an area larger than an area of a second surface portion of the end portion (1) facing the counter electrode (180) and functioning as an electrode.
摘要:
Die Erfindung betrifft eine elektrostatische Trennvorrichtung in der Art eines Freifallscheiders zur Sortierung triboelektrisch aufgeladener Stoffgemische, die dadurch gekennzeichnet ist, daß an jeder der Elektroden, die ein Elektrodenpaar bilden, jeweils eine separate Spannungsquelle 9a, 9b derart angeschlossen ist, daß die eine Quelle eine positive Spannung gegen das Potential Erde und die andere eine negative Spannung gegen das Potential Erde liefert und dadurch in Scheidermitte die Potentialdifferenz gegen Erde gleich Null ist.
