Claims
- 1. In a plate heat exchanger comprising a frame including a fixed head and a fixed supporting pillar, and a top rail extending between said head and said supporting pillar, and a pack of plates carried by said top rail and compressed between said fixed head and a movable follower mounted for movement on the top rail; the improvement comprising means for attaching the top rail to the fixed head and fixed supporting pillar in a readily releasable manner so that the top rail and pack of plates can be lifted bodily and together from the head and supporting pillar, the follower being releasably mounted on the top rail, and means for temporarily accommodating the follower on the support pillar when the top rail is removed to position the follower clear of the top rail and pack of plates so that the rail and pack of plates can be lifted as a unit.
- 2. A plate heat exchanger as claimed in claim 1, in which cam means is provided to lift the follower slightly in relation to the support pillar to release the follower from the top rail, and clamping means is provided to attach the follower to the support pillar with freedom for the required lifting movement.
- 3. A plate heat exchanger as claimed in claim 1, in which ramp means is provided to lift the follower slightly to release it from the top rail as it approaches the support pillar.
- 4. A plate heat exchanger as claimed in claim 1, in which the top rail is provided with means for attachment of lifting shackles.
- 5. A plate heat exchanger as claimed in claim 1, in which means is provided for blocking more than limited movement of the plates of the pack along the top rail during transport of the pack and top rail.
- 6. A plate heat exchanger as claimed in claim 5, in which the top rail is provided with a fixed stop plate at the head end and a removable stop plate is securable at or near the follower end of the pack.
- 7. A plate heat exchanger as claimed in claim 6, in which the removable stop plate is clampable to the top rail in any selected position.
- 8. A plate heat exchanger as claimed in claim 6, in which the removable stop plate is securable to a pre-formed hole in the top rail.
- 9. A plate heat exchanger as claimed in claim 1, in which the plates of the pack slide on the top rail with minimal clearance so as to be substantially restricted against any but longitudinal movement on the said rail.
- 10. In a frame for a plate heat exchanger comprising a fixed head, a fixed supporting pillar and a fixed top rail extending between the head and supporting pillar and supporting a movable follower: the improvement comprising means for attaching the top rail to the head and supporting pillar in a readily releasable manner so as to be lifted therefrom, the follower being releasably mounted on the top rail, and means for temporarily accommodating the follower on the support pillar when the top rail is removed to position the follower clear of the top rail and pack of plates so that the rail and pack of plates can be lifted as a unit.
- 11. A frame as claimed in claim 10, in which cam means is provided to lift the follower slightly in relation to the support pillar to release the follower from the top rail and clamping means is provided to attach the follower to the support pillar with freedom for the required lifting movement.
- 12. A frame as claimed in claim 10, in which ramp means is provided to lift the follower slightly to release it from the top rail as it approaches the support pillar and clamping means is provided to attach the follower to the support pillar.
- 13. A frame as claimed in claim 10, in which the top rail is provided with means for attachment of lifting shackles.
- 14. A plate heat exchanger as claimed in claim 1, in which said means for temporarily accommodating the follower comprises means for lifting the follower to release the follower from the top rail.
- 15. A frame as claimed in claim 10, in which said means for temporarily accomodating the follower comprises means for lifting the follower to release the follower from the top rail.
- 16. A plate heat exchanger as claimed in claim 1 wherein said top rail includes means for coupling to a lifting mechanism.
- 17. A frame as claimed in claim 10 wherein said top rail includes means for coupling to a lifting mechanism.
