Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a detachable plate heat exchanger. Background Technology

[0002] Nowadays, heat exchangers are devices that transfer part of the heat of a hot fluid to a cold fluid. They are also called heat exchangers. Detachable plate heat exchangers are common in the heat exchanger field. Detachable plate heat exchangers use common heat exchanger technologies and are convenient and practical. In daily use, when the plates of a detachable plate heat exchanger need to be cleaned, the detachable plate heat exchanger needs to be disassembled.

[0003] According to a public notice of a detachable plate heat exchanger (publication number: CN221280025U), in the above application, the user drives the lead screw to rotate via a handle. The lead screw is threadedly connected to the slider, so the slider can move along the direction of the slide groove. The two sets of sliders drive the two sets of clamping plates to move towards the fixed plate. They stop moving when they reach one side of the fixed plate, thereby clamping the fixed plate. Multiple sets of grooves allow clamping bolts to pass through the two sets of fixed plates for fixation. Multiple sets of nuts are threadedly connected to multiple sets of clamping bolts, which can achieve the effect of clamping and fixing the two sets of fixed plates.

[0004] However, in actual use, although the plates of the above-mentioned equipment can be disassembled, the nuts on the fixing screws may loosen after periodic disassembly and installation. Furthermore, the vibration generated during the use of the equipment may cause the plates to vibrate up and down, ultimately resulting in overall instability. In view of this, we propose a detachable plate heat exchanger. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable plate heat exchanger to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable plate heat exchanger, comprising a base, a fixed plate fixedly connected to the outer wall of the base, a threaded rod rotatably mounted on the inner wall of the base, a threaded slider threadedly connected to the outer wall of the threaded rod, a movable plate fixedly connected to the outer wall of the threaded slider, a flange water pipe assembly provided on the outer wall of the movable plate, a plate provided on the inner wall of the movable plate, a disassembly positioning assembly provided on the outer wall of the movable plate, the disassembly positioning assembly comprising a positioning pull plate, the positioning pull plate detachably mounted on the outer wall of the movable plate, an upper pressure plate fixedly connected to the outer wall of the positioning pull plate, a nut detachably mounted on the outer wall of the positioning pull plate, a limit sleeve fixedly connected to the outer wall of the nut, and an elastic telescopic rod fixedly connected to the outer wall of the fixed plate; A lever is fixedly connected to the outer wall of the elastic telescopic rod. A lower plate is fixedly connected to the outer wall of the elastic telescopic rod, and a lower insertion rod is fixedly connected to the outer wall of the lower plate. An upper plate is fixedly connected to the outer wall of the elastic telescopic rod, and an upper insertion rod is fixedly connected to the outer wall of the upper plate.

[0007] Preferably, the center line of the lower insertion rod and the center line of the limiting sleeve are on the same straight line, and the outer wall of the lower insertion rod is adapted to the inner wall of the limiting sleeve, so that the lower insertion rod can be smoothly inserted into the limiting sleeve.

[0008] Preferably, the elastic telescopic rods are provided in two sets, and the two sets of elastic telescopic rods are arranged on both sides with the center plane of the fixed plate as a mirror image.

[0009] Preferably, the number of plates is several, and the several plates are arranged in a linear array on the outer wall of the base.

[0010] Preferably, the outer wall of the fixing plate is provided with a guide assembly, the guide assembly includes a fixing frame, the fixing frame is fixedly connected to the outer wall of the fixing plate, and the outer wall of the upper plate is provided with a sliding groove.

[0011] Preferably, the number of fixing frames is two sets, and the two sets of fixing frames are arranged on both sides mirroring the center plane of the fixing plate.

[0012] Preferably, the inner wall of the upper plate is slidably connected to the outer wall of the fixed frame, so that the upper plate can be moved smoothly.

[0013] Compared with the prior art, this utility model provides a detachable plate heat exchanger, which has the following advantages: 1. In this detachable plate heat exchanger, after the fixed plate and the moving plate initially position the plates, a positioning pull plate can be inserted. This allows the positioning pull plate to provide secondary clamping for the initially positioned plates. At the same time, the upper pressure plate will move synchronously to limit the top of the plates. Then, the elastic telescopic rod can be pulled back, and the nut can be tightened to move the limiting sleeve, thus limiting the positioning pull plate. Subsequently, the lower insertion rod on the elastic telescopic rod can be inserted into the limiting sleeve. At the same time, the upper insertion rod in the upper plate will form an additional limit on the upper pressure plate, ultimately improving the overall positioning effect and preventing loosening between the nut and the plates.

[0014] 2. In this detachable plate heat exchanger, when the elastic telescopic rod is retracted and extended by conveniently pulling the lever, the fixing frame will provide an additional balancing force to the upper plate. This allows the lower insertion rod to be smoothly inserted and removed when the elastic telescopic rod is extended and retracted, and the upper insertion rod can also move smoothly and synchronously, ultimately further improving the overall practicality.

[0017] like Figures 1-7 As shown, this utility model provides a technical solution: a detachable plate heat exchanger, including a base 1, a fixed plate 2 fixedly connected to the outer wall of the base 1, a threaded rod 3 rotatably installed on the inner wall of the base 1, a threaded slider 4 threadedly connected to the outer wall of the threaded rod 3, a movable plate 5 fixedly connected to the outer wall of the threaded slider 4, a flange water pipe assembly 6 provided on the outer wall of the movable plate 5, a plate 9 provided on the inner wall of the movable plate 5, and a disassembly positioning assembly 7 provided on the outer wall of the movable plate 5. The disassembly positioning assembly 7 includes a positioning pull plate 701, which is detachably installed on the outer wall of the movable plate 5. An upper pressure plate 702 is fixedly connected to the outer wall of the positioning pull plate 701, and a nut 703 is detachably installed on the outer wall of the positioning pull plate 701. A limit sleeve 704 is fixedly connected to the outer wall of the nut 703, and an elastic telescopic rod 705 is fixedly connected to the outer wall of the fixed plate 2.

[0018] Furthermore, the lever 706 is fixedly connected to the outer wall of the elastic telescopic rod 705, the outer wall of the elastic telescopic rod 705 is fixedly connected to the lower plate 707, the outer wall of the lower plate 707 is fixedly connected to the lower insertion rod 708, the outer wall of the elastic telescopic rod 705 is fixedly connected to the upper plate 709, and the outer wall of the upper plate 709 is fixedly connected to the upper insertion rod 710.

[0019] In the embodiments of this utility model, the center line of the lower insertion rod 708 and the center line of the limiting sleeve 704 are on the same straight line, and the outer wall of the lower insertion rod 708 is adapted to the inner wall of the limiting sleeve 704, so that the lower insertion rod 708 can be smoothly inserted into the limiting sleeve 704. The number of elastic telescopic rods 705 is two sets, and the two sets of elastic telescopic rods 705 are mirror images of the center plane of the fixing plate 2 on both sides. The number of plates 9 is several, and the several plates 9 are arranged in a linear array on the outer wall of the base 1.

[0020] Furthermore, the outer wall of the fixed plate 2 is provided with a guide component 8, which includes a fixing frame 801. The fixing frame 801 is fixedly connected to the outer wall of the fixed plate 2. The outer wall of the upper plate 709 is provided with a sliding groove 802. There are two sets of fixing frames 801, and the two sets of fixing frames 801 are mirror images of the center plane of the fixed plate 2 on both sides. The inner wall of the upper plate 709 is slidably connected to the outer wall of the fixing frame 801, so that the upper plate 709 can move smoothly.

[0021] In this utility model, during daily use, the displacement of the threaded slider 4 can be adjusted by rotating the threaded rod 3 to achieve the displacement of the moving plate 5. This allows for the installation and removal of the plate 9 between the fixed plate 2 and the moving plate 5. After the fixed plate 2 and the moving plate 5 have initially positioned the plate 9, the positioning pull plate 701 can be inserted. This allows the positioning pull plate 701 to provide secondary clamping for the initially positioned plate 9. At this time, the upper pressure plate 702 will also move synchronously to limit the top of the plate 9. Then, the elastic telescopic rod 705 can be pulled back, and the nut 703 can be tightened, simultaneously driving the limiting sleeve 704 to move, thus limiting the positioning pull plate 701. Subsequently, the lower insertion rod 708 on the elastic telescopic rod 705 can be inserted into the limiting sleeve 704. At the same time, the upper insertion rod 710 in the upper plate 709 will provide additional limitation for the upper pressure plate 702, ultimately improving the overall positioning effect and preventing loosening between the nut 703 and the plate 9.

[0022] When the lever 706 is pulled to retract and extend the elastic telescopic rod 705, the fixing bracket 801 provides an additional balancing force to the upper plate 709. This allows the lower insertion rod 708 to be inserted and removed smoothly when the elastic telescopic rod 705 is extended and retracted, and the upper insertion rod 710 can also move smoothly in sync, ultimately further improving the overall practicality.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
