Description

Technical Field

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

[0002] The detachable plate heat exchanger is composed of multiple corrugated metal plates. It not only has the advantages of compact structure, small floor area, and light weight, but also has high heat exchange performance and convenient cleaning, disassembly, and assembly advantages. Therefore, it is widely used in multiple industrial fields.

[0003] Most of the existing detachable plate heat exchangers are connected and fixed through clamping bolts. The connection by bolts facilitates the installation and removal of the heat exchanger. However, this method requires workers to remove and tighten each bolt, which is not only cumbersome to operate, but also wastes time and reduces the work efficiency of workers. Moreover, the bolts are prone to damage and thread slipping after multiple uses, which easily affects the fastening effect. After retrieval, it is found that the technical solution provided by the utility model with the application number CN202222665175.7 also has the above problems. Summary of the Utility Model

The inner surface of the connecting seat 20 communicates with the first clamping plate 1. The right surface of the first clamping plate 1 is fixedly connected with a working box 2. The inner surface of the working box 2 is fixedly connected with a plate 4. The right surface of the first clamping plate 1 is fixedly connected with a fixed rod 5. The outer surface of the fixed rod 5 is slidably connected with a second clamping plate 3. The left surface of the second clamping plate 3 is fixedly connected with a limit rod 18. The inner surface of the limit seat 19 is slidably connected with the limit rod 18. The lower surfaces of the first clamping plate 1 and the second clamping plate 3 are both fixedly connected with floor footings 21. The number of the floor footings 21 is four and they are arranged in a rectangular array. A cavity 6 is arranged inside the fixed rod 5. The inner wall of the cavity 6 is fixedly connected with a first spring 7. The other end of the first spring 7 is fixedly connected with a block 8. The outer surface of the block 8 is slidably connected with the cavity 6. The outer surface of the block 8 is slidably connected with the second clamping plate 3.

[0020] The fixed rod 5 is inserted into the second clamping plate 3. The second clamping plate 3 pushes the block 8 into the cavity 6. When the fixed rod 5 is completely inserted into the second clamping plate 3, the block 8 pops out under the action of the first spring 7 and is snapped into the second clamping plate 3 to fix the fixed rod 5, so that the first clamping plate 1 and the second clamping plate 3 are fixedly connected. The limit rod 18 and the limit seat 19 can play a role in limiting and guiding the fixed rod 5, facilitating the synchronous insertion of the four fixed rods 5 into the second clamping plate 3.

[0021] The right surface of the second clamping plate 3 is provided with a limiting sliding groove 9. The left inner wall of the limiting sliding groove 9 is fixedly connected with a second spring 10. The other end of the second spring 10 is fixedly connected with a connecting rod 11. The outer surface of the connecting rod 11 is slidably connected with the limiting sliding groove 9. The right surface of the connecting rod 11 is fixedly connected with a pressing block 16. The outer surface of the connecting rod 11 is fixedly connected with an adjusting seat 12. The outer surface of the adjusting seat 12 is rotatably connected with an adjusting rod 13.

The outer surface of the connecting frame 14 is slidably connected with the guiding sliding groove 17.

[0022] During specific use, pressing the pressing block 16 drives the connecting rod 11 to move. The connecting rod 11 drives the adjusting rod 13 to open through the adjusting seat 12, causing the two connecting frames 14 to move along the guiding sliding groove 17 towards both sides. Dong Er drives the slider 15 to push the clamping block 8 into the cavity 6, thereby realizing the removal of the second clamping plate 3.

[0023] During installation, the working box 2 is clamped between the first clamping plate 1 and the second clamping plate 3. The fixing rods 5 are inserted into the second clamping plate 3. The limiting rods 18 and the limiting seats 19 can play a role in limiting and guiding the fixing rods 5, facilitating the synchronous insertion of the four fixing rods 5 into the second clamping plate 3. During the insertion of the fixing rods 5, the second clamping plate 3 pushes the clamping block 8 into the cavity 6. When the fixing rods 5 are completely inserted into the second clamping plate 3, the clamping block 8 pops out under the action of the first spring 7 and snaps into the second clamping plate 3 to fix the fixing rods 5, thereby fixedly connecting the first clamping plate 1 and the second clamping plate 3. Pressing the pressing block 16 drives the connecting rod 11 to slide along the limiting sliding groove 9. The connecting rod 11 drives the adjusting seat 12 to move, causing the adjusting rod 13 to open, so that the two connecting frames 14 move along the guiding sliding groove 17 towards both sides. The connecting frame 14 drives the slider 15 to push the clamping block 8 into the cavity 6, thereby realizing the removal of the second clamping plate 3. After releasing the hand, the second spring 10 drives the connecting rod 11 to reset, thereby driving the connecting frame 14 and the slider 15 to reset, facilitating the next connection of the fixing rods 5.
