Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a detachable plate heat exchanger. Background Art

[0002] When the existing detachable plate heat exchanger needs to disassemble the bottom plate during operation, first slide the clamping rod inward, the clamping rod will drive the limiting plate to slide, and the limiting plate will squeeze the second spring to slide. When the clamping rod squeezes the clamping block outwards from the clamping groove, the clamping block will squeeze the sliding plate to slide in the sliding groove and squeeze the first spring. Then, the plate body can be pulled upward to drive the fixing plate to slide out of the groove. When the extrusion force on the first spring is cancelled, the clamping block will return to its initial state. Then release and push the clamping rod. Since the extrusion force on the second spring is cancelled, the second spring will rebound the limiting plate, and the limiting plate will drive the clamping rod to return to its initial state. Then insert the fixing plate at the bottom of the new plate body into the groove. The clamping block will drive the sliding plate to squeeze the first spring to slide in the sliding groove under the extrusion force of the inner wall of the groove. When the clamping block is located in the clamping groove, the first spring will rebound the sliding plate to drive the clamping block to be inserted into the clamping groove to complete the replacement of the plate body.

A rotating motor 3 is fixedly connected to the right surface of the fixed clamping plate 4. The output end of the rotating motor 3 is fixedly connected to a lead screw 6. The outer surface of the lead screw 6 is rotatably connected to the fixed clamping plate 4. The outer surface of the lead screw 6 is threadedly connected to a movable clamping plate 8. The inner surface of the movable clamping plate 8 is slidably connected to a slide bar 7. The right surface of the slide bar 7 is fixedly connected to the fixed clamping plate 4. The lower surface of the movable clamping plate 8 is slidably connected to the bottom plate 1. A spring 10 is fixedly connected to the right surface of the movable clamping plate 8. One end of the spring 10 away from the movable clamping plate 8 is fixedly connected to a contact plate 11. The right surface of the contact plate 11 is movably connected to a plate body 2. The right surface of the plate body 2 is slidably connected to the fixed clamping plate 4.

[0021] A first connecting pipe 12 is slidably connected to the inner surface of the plate body 2. The right surface of the first connecting pipe 12 is fixedly connected to the fixed clamping plate 4. A second connecting pipe 13 is slidably connected to the inner surface of the first connecting pipe 12. The left surface of the first connecting pipe 12 is fixedly connected to a conical pipe 14. The outer surface of the conical pipe 14 is slidably connected to the plate body 2. The inner surface of the conical pipe 14 is slidably connected to the second connecting pipe 13. The outer surface of the second connecting pipe 13 is slidably connected to the plate body 2. The right surface of the second connecting pipe 13 is fixedly connected to the movable clamping plate 8. An electric telescopic rod 9 is fixedly connected to the left surface of the bottom plate 1. The right surface of the electric telescopic rod 9 is movably connected to the movable clamping plate 8. The rotating motor 3 and the electric telescopic rod 9 are both electrically connected to an external power source.

[0022] Heat transfer is achieved through the gap between the medium and the heat exchanger water pipe 5 by means of the plate body 2. When disassembling the plate body 2, separate the left and right plate bodies 2 of the plate body 2 to be disassembled and move them closer to the movable clamping plate 8 and the fixed clamping plate 4 respectively. The left plate body 2 of the plate body 2 to be disassembled is on the second connecting pipe 13, and the first connecting pipe 12 of the right plate body 2 of the plate body 2 to be disassembled. Operate the rotating motor 3 to drive the lead screw 6 to rotate. The movable clamping plate 8 moves in a straight line left and right on the bottom plate 1 through the thread transmission of the lead screw 6 and the limitation of the slide bar 7. After turning the movable clamping plate 8 away from the lead screw 6, a gap is generated when the second connecting pipe 13 is separated from the first connecting pipe 12, and the plate body 2 to be disassembled can be removed from the gap. When installation is required, operate the electric telescopic rod 9 to push the movable clamping plate 8 close to the lead screw 6, and the rotation of the lead screw 6 realizes the threaded connection with the movable clamping plate 8. The second connecting pipe 13 is sleeved into the first connecting pipe 12 and the conical pipe 14. The left plate body 2 slides into the first connecting pipe 12 under the guidance of the conical pipe 14. As the movable clamping plate 8 approaches, the contact plate 11 contacts the plate body 2, and the spring 10 plays a buffering role during the process of the movable clamping plate 8 squeezing the plate body 2.
