Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, specifically a fully counter-current plate heat exchanger that is easy to disassemble and assemble. Background Technology

[0002] A plate heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It consists of multiple heat exchange plates. These plates have internal flow channels for either the hot or cold fluid, and adjacent plates form flow channels for another fluid. When the hot and cold fluids flow in their respective channels, they exchange heat through the heat exchange plates, thus achieving heat exchange.

[0003] However, existing plate heat exchangers have some structural problems. The front and rear plates are typically connected and fixed by multiple bolts, making the assembly and disassembly of the heat exchange plates extremely inconvenient. When maintenance or replacement of the heat exchange plates is required, all bolts must be removed first, followed by disassembly of the connections between the front and rear plates and the upper and lower guide rods. This entire disassembly and assembly process is not only cumbersome but also requires tools such as wrenches, significantly reducing the efficiency of heat exchanger maintenance.

[0004] Based on this, a fully counter-current plate heat exchanger that is easy to install and disassemble is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

During installation, the heat exchange plate 300 is slidably installed between the front end plate 100 and the rear end plate 200. Then, the movable component 700 drives the rear end plate 200 to move along the upper guide rod 500 and the lower guide rod 600 to the side of the front end plate 100. The rear end plate 200 and the front end plate 100 clamp the heat exchange plate 300, and the locking component 800 locks the position of the rear end plate 200.

[0022] In one embodiment, such as Figure 1 As shown, the front end plate 100 is provided with a first fixing seat 101 at the lower end, and a connection port 102 is provided on one side of the front end plate 100. The connection port 102 is used to connect the heat exchange fluid.

[0023] In one embodiment, such as Figure 4 As shown, the rear end plate 200 is provided with a horizontal mounting groove 201, and two through vertical mounting grooves 202 are symmetrically provided above and below the horizontal mounting groove 201. A limiting slide groove 203 is provided in the middle section of the vertical mounting groove 202. Both the horizontal mounting groove 201 and the vertical mounting groove 202 are used to install the locking component 800.

[0024] In one embodiment, such as Figure 1 As shown, the lower end of the support column 400 has a second fixing seat 401. During installation, the heat exchanger is fixed in the designated position by the second fixing seat 401 and the first fixing seat 101.

[0025] In one embodiment, such as Figure 2 As shown, the lower end of the upper guide rod 500 is uniformly provided with first locking holes 501, and a first disassembly groove 502 is provided on one side of the first locking hole 501. The first locking hole 501 is used to lock the upper end of the rear end plate 200, and the first disassembly groove 502 is used for disassembling and assembling the heat exchange plate 300.

[0026] In one embodiment, such as Figure 1 As shown, the upper end of the lower guide rod 600 is uniformly provided with second locking holes 601, and a second disassembly groove 602 is provided on one side of the second locking hole 601. The second disassembly groove 602 corresponds to the position of the first disassembly groove 502. The second locking hole 601 is used to lock the lower end of the rear end plate 200, and the second disassembly groove 602 is used for disassembling and assembling the heat exchange plate 300.

[0027] In one embodiment, such as Figure 3 As shown, the movable component 700 includes a mounting base 701 fixed on the support column 400. The mounting base 701 is provided with a sliding groove 702. A first screw 703 is rotatably connected to the mounting base 701. The first screw 703 is provided with a bidirectional thread. A movable seat 704 is threadedly connected to the first screw 703. A slider 705 is provided on one side of the movable seat 704. The slider 705 is slidably disposed in the sliding groove 702. A connecting rod 706 is hinged to the other side of the movable seat 704. The other end of the connecting rod 706 is hinged to the rear end plate 200. A rotating wheel 707 is provided at one end of the first screw 703. A handle 708 is rotatably connected to the rotating wheel 707. In use, the rotating wheel 707 is rotated by the handle 708, which drives the first screw 703 to rotate, causing the movable seat 704 to slide laterally along the sliding groove 702. At the same time, the rear end plate 200 is driven to slide along the upper guide rod 500 and the lower guide rod 600 through the connecting rod 706.

[0028] In one embodiment, such as Figure 4As shown, the locking assembly 800 includes a second screw 801 threadedly connected to a horizontal mounting groove 201 and a movable rod 804 slidably mounted in a vertical mounting groove 202. One end of the second screw 801 has a cone head 802, and the other end has a rotating seat 803. A limiting ring 805 is provided on the movable rod 804, and the limiting ring 805 is slidably mounted in a limiting groove 203. A spring 806 is provided on one side of the limiting ring 805. In use, rotating the rotating seat 803 causes the cone head 802 to squeeze... Press the movable rod 804 to drive it upward, so that one end of the movable rod 804 is inserted into the first locking hole 501 and the second locking hole 601, thereby locking the rear end plate 200. When the lock is released, rotate the rotating seat 803 in the opposite direction to move the second screw 801 outward until the cone head 802 leaves the movable rod 804. Under the action of the spring 806, the movable rod 804 moves inward until the end of the movable rod 804 leaves the first locking hole 501 and the second locking hole 601.

[0029] The above embodiment discloses a fully counter-flow plate heat exchanger that is easy to assemble and disassemble. During installation, the heat exchange plates 300 are installed from the first disassembly groove 502 and the second disassembly groove 602 between the upper guide rod 500 and the lower guide rod 600. Then, by rotating the rotating wheel 707 through the gripping rod 708, the first screw 703 is driven to rotate, causing the movable seat 704 to slide laterally along the sliding groove 702. At the same time, the connecting rod 706 drives the rear end plate 200 to slide along the upper guide rod 500 and the lower guide rod 600. The heat exchange plates 300 are clamped by the rear end plate 200 and the front end plate 100. Then, the rotating seat 803 is rotated, causing the cone 802 to press the movable rod 804, driving the movable rod 804 to move upward, so that one end of the movable rod 804 is inserted into the first locking hole 501 and the second locking hole 601, thereby locking the rear end plate 200.
