摘要:
An inspection unit (1) for vats or tanks comprising a frame (2) at least partially housable inside a through opening (A) of a wall (P) of the vat or tank (S) and having a peripheral undercut (3) defining at least partially a passage opening between an inner environment and an environment outside the vat or tank (S). The inspection unit 1 further comprises a door (4) hinged to the frame (2) and reversibly movable between a closing position, in which it is substantially abutting against an abutment portion (5) of the frame (2), and an opening position. Furthermore, the inspection unit 1 comprises a locking device (6) connected or connectable to the door (4) and activatable on a stop portion (7) of the frame (2) to generate a clamping force (F) adapted to push said door (4) against the abutment portion (5). In particular, the undercut (3) defines at least partially the abutment portion (5) and/or the stop portion (7).

Disclosed herein is an inversion unit comprising a housing (2), a reel (4) for a liner partially arranged in the housing (2), and a base assembly (6), the housing (2) being arranged on the base assembly (6), said housing (2) comprising a gas inlet (36), an outlet (8) for the liner, an opening (10) comprising a window (14) and a window locking mechanism (12) for closing and opening the window (14). The window locking mechanism (12) is designed to be manoeuvred into an open position in which the window (14) is open and unlocked and a closed position in which the window (14) is closed and locked. The window locking mechanism (12) is designed as a bayonet catch and comprises a motion link assembly (16) and a matching projection assembly (18), the window locking mechanism (12) further comprising a handle (20) and a hinge (28), the handle (20) being pivotably connected to the hinge (28) wherein one of the motion link assembly (16) or the matching projection assembly (18) is arranged on the window (14) and the other of the matching projection assembly (18) or the motion link assembly (16) is arranged on an edge of the opening (10), wherein the hinge (28) is arranged on the housing (2) and wherein the handle (20) is pivotably connected to the window (14) so that the window (14) can be easily opened and closed in a bayonet catch manner using the handle (20).
摘要:
Gegenstand der Erfindung ist eine Vorrichtung zum Homogenisieren fließfähiger Stoffe. Am Boden eines Mischbehälters ist ein Homogenisator angeordnet. Dieser Homogenisator fördert über einen Zulauf (21) eintretendes Mischgut in einen Ablauf (22), aus dem es wahlweise über ein Umlaufleitung zurück in den oberen Bereich des Mischbehälters oder über einen Ringkanal (24) in den Bodenbereich dieses Behälters rückgeführt werden kann. Die Umlaufleitung ist über Ventile absperrbar. Erfindungsgemäß ist vorgesehen, daß ein mit einer Federeinrichtung (25) vorgespannter Dichtring (26) den Ringkanal (24) gegenüber dem Ablauf (22) verschließ. Bei geöffneten Ventilen wird daher das Mischgut über die Umlaufleitung umgewälzt. Werden die Ventile geschlossen, steigt der Druck im Homogenisatorablauf (22), so daß der Dichtring (26) gegen die Kraft der Federeinrichtung (25) angehoben wird und das Mischgut aus dem Ablauf (22) über den Ringkanal (24) zurück in den Behälter strömen kann.

The invention relates to a melter, comprising a block (2) having a detachable shell (6), in which there is housed a melting chamber (3) provided with an upper opening that is closed with a hinged and detachable lid (11), the chamber (3) being arranged on lower supports (7), with the freedom to expand upwards, the opening of said chamber (3) incorporating a gasket (8) having an upwardly inclined flexible lip in the outer part on which the shell (6) rests, establishing a leak-tight closure with respect to the chamber (3), whereas on the gasket (8) there is arranged a frame (9) having an upward vertical flange, with respect to which the lid (11) that closes on the gasket (8) is assembled, such that when the chamber (3) expands due to the temperature, the flexible lip allows the expansion maintaining leak-tightness.

摘要:
A closure system which provides a lubricated lock ring on a hinged door assembly rather than proximate a pressure vessel is provided. The configuration of this system removes lubricants from the region immediately adjacent a pressure vessel entrance to be sealed by the door assembly. A shorter entrance tunnel for access to the pressure vessel interior is also provided by this configuration. A clamp ring having radially extending lugs is rigidly affixed proximate to and partially defining the pressure vessel entrance. The door has a continuous thread about an outer circumferential surface thereof. A lock ring having a complementary interior continuous thread is in rotational communication with the threaded circumferential surface of the door. The lock ring also has plural, inwardly projecting lugs which are capable of passing between the clamp ring lugs when the door is swung toward the clamp ring. The lock ring is capable of being rotated by a rotary actuator for engagement of the clamp ring lugs with the lock ring lugs. The door may be provided with a sight glass and light source for viewing the interior of the pressure vessel. The door may also be provided with a face plate on the door for maintaining the lock ring in concentric alignment with the door to prevent the cooperating threads from binding. Limit switches may be employed to detect when clamp ring and lock ring lugs are aligned for door closure, and when the lock ring is rotated by the desired amount. A proximity sensor may be provided for making sure the door is in a closed position before enabling lock ring rotation.
