Description

Technical Field

[0001] This utility model relates to the technical field of plate heat exchanger installation, specifically a plate heat exchanger that can be disassembled in a staggered manner. Background Technology

[0002] Plate heat exchangers are high-efficiency heat exchange devices consisting of a series of metal plates with corrugated or uneven structures stacked together. Two adjacent plates form an interlaced flow structure through sealing gaskets. Hot and cold fluids flow in their respective channels and transfer heat through the plate contact points. High-temperature fluids and low-temperature fluids enter different channels respectively. The corrugated structure of the plates enhances turbulence, and heat is transferred from the high-temperature fluid to the low-temperature fluid, thus realizing energy transfer.

[0003] When assembling existing detachable plate heat exchangers, the two wall plates are fastened together by multiple screws to fix the entire plate bundle together. The process of aligning and locking the threaded rods one by one is very cumbersome, especially in large or complex heat exchangers. Each threaded rod needs to be aligned individually. If the locking force is uneven, it may cause local stress concentration between the plates. Realigning and locking all the threaded rods will increase maintenance costs and time, and reduce installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a plate heat exchanger that can be disassembled in a staggered manner, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A plate heat exchanger that can be disassembled in a staggered manner includes a first clamping plate and a second clamping plate. At least one set of first connecting plates are symmetrically arranged on the first clamping plate, and a cutting groove is formed on the end of the first connecting plate away from the first clamping plate. At least one set of second connecting plates are symmetrically arranged on the second clamping plate. The end of the second connecting plate away from the second clamping plate is provided with a guide protrusion that can be misaligned and inserted into the cutting groove. After the guide protrusion is inserted into the cutting groove, the first clamping plate and the second clamping plate can be automatically aligned, and the locking mechanism provided in the cutting groove locks the second connecting plate.

[0006] As described above, the plate heat exchanger is detachable and can be disassembled in a staggered manner: a locking hole is formed on the guide protrusion, and the locking mechanism can be inserted into the locking hole.

[0007] As described above, the plate heat exchanger that can be disassembled in a staggered manner has a cylindrical cavity formed on the first connecting plate, and a pressing member is provided in the cylindrical cavity to adjust the locking force of the locking mechanism.

[0008] As described above, the plate heat exchanger is detachable and can be disassembled in a staggered manner: the locking mechanism includes a plug-in post, one end of which is slidably disposed in the cylindrical cavity, and the other end extends out of the cylindrical cavity and can be inserted into the locking hole; It also includes a spring, which is disposed in the cylindrical cavity, with one end of the spring abutting against the insertion post and the other end abutting against the extrusion member.

[0009] As described above, the plate heat exchanger is detachable and can be disassembled in a staggered manner: the extrusion member includes a pusher plate, which is slidably disposed within the cylindrical cavity, and the movement of the pusher plate is controlled by a driving moving member disposed on the first connecting plate.

[0010] As described above, the plate heat exchanger that can be disassembled in a staggered manner has at least one set of limiting grooves on the cylindrical cavity, and a limiting block that slides with the limiting grooves is provided on the push plate.

[0011] As described above, the plate heat exchanger is detachable and can be disassembled in a staggered manner: the driving moving part includes a threaded rod arranged along the axial direction of the push plate, the threaded rod passes through the cylindrical cavity and is threadedly connected to the first connecting plate, one end of the threaded rod is rotatably connected to the push plate, and a knob is fixedly installed on the other end.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When assembling a plate heat exchanger, after the first and second connecting plates are misaligned and inserted, the guide protrusions, under the action of gravity, can insert into the grooves, achieving automatic alignment of the inlet and outlet ports on the first and second clamping plates. At this time, the locking mechanism pre-locks the second connecting plate. By adjusting the locking force of the locking mechanism, the second connecting plate can be further locked to achieve a stable connection between the first and second clamping plates. Through the automatic alignment and locking mechanism, the precise alignment of the inlet and outlet ports is ensured, thereby improving the heat exchange efficiency and overall performance of the heat exchanger. Moreover, it eliminates the need to use multiple threaded rods for one-to-one alignment and connection, reducing the number of tools and equipment required during the assembly process, thus significantly shortening the assembly time and improving the installation efficiency of the plate heat exchanger.

Detailed Implementation

[0020] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] Please see Figures 1-6 In this embodiment of the utility model, a plate heat exchanger that can be disassembled in a staggered manner includes a first clamping plate 1 and a second clamping plate 2. At least one set of first connecting plates 3 are symmetrically arranged on the first clamping plate 1, and a cutting groove 301 is provided on the end of the first connecting plate 3 away from the first clamping plate 1. At least one set of second connecting plates 4 are symmetrically arranged on the second clamping plate 2. The end of the second connecting plate 4 away from the second clamping plate 2 is provided with a guide protrusion 401 that can be misaligned and inserted into the cutting groove 301. After the guide protrusion 401 is inserted into the cutting groove 301, the first clamping plate 1 and the second clamping plate 2 can be automatically aligned, and the locking mechanism provided in the cutting groove 301 locks the second connecting plate 4.

[0024] In this embodiment, when assembling the plate heat exchanger, after the first connecting plate 3 and the second connecting plate 4 are misaligned and inserted, the guide protrusion 401 can be inserted into the cutting groove 301 under the action of gravity, realizing the automatic alignment of the inlet and outlet ports on the first clamping plate 1 and the second clamping plate 2. At this time, the locking mechanism is initially pre-locked with the second connecting plate 4. By adjusting the locking force of the locking mechanism, the second connecting plate 4 can be further locked to achieve a stable connection between the first clamping plate 1 and the second clamping plate 2. Through the automatic alignment and locking mechanism, the precise alignment of the inlet and outlet ports is ensured, thereby improving the heat exchange efficiency and overall performance of the heat exchanger. Moreover, it eliminates the need to use multiple connecting rods for one-to-one alignment and connection, reducing the number of tools and equipment required during the assembly process, thereby significantly shortening the assembly time and improving the installation efficiency of the plate heat exchanger.

[0025] Preferably, a locking hole 402 is formed on the guide protrusion 401, and the locking mechanism can be inserted into the locking hole 402.

[0026] A cylindrical cavity 302 is formed on the first connecting plate 3, and a pressing member is provided in the cylindrical cavity 302 to adjust the locking force of the locking mechanism.

[0027] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The locking mechanism includes a plug-in post 5, one end of which is slidably disposed in the cylindrical cavity 302, and the other end extends out of the cylindrical cavity 302 and can be inserted into the lock hole 402; It also includes a spring 7, which is disposed in the cylindrical cavity 302. One end of the spring 7 abuts against the insertion post 5, and the other end abuts against the extrusion member.

[0028] Preferably, a tapered portion 501 is formed on the end of the insertion post 5 away from the cylindrical cavity 302.

[0029] In the initial state, the spring 7 is in its natural state. When the guide protrusion 401 is aligned with the cutting groove 301 and inserted, it squeezes the conical part 501. At this time, the conical part 501 is subjected to an inclined force, causing the insertion post 5 to move towards the cylindrical cavity 302 to make way for the insertion of the guide protrusion 401. The spring 7 is compressed and stores elastic potential energy. When the guide protrusion 401 completes insertion into the cutting groove 301, the inlet and outlet ports on the first clamping plate 1 and the second clamping plate 2 are precisely aligned. The locking hole 402 on the guide protrusion 401 is aligned with the insertion post 5. At this time, the insertion post 5 loses its compression and, under the elastic force of the spring 7, the conical part 501 is inserted into the locking hole 402 to achieve initial automatic locking of the second connecting plate 4, avoiding the first clamping plate 1 and the second clamping plate 2 from shifting due to improper human operation.

[0030] For further solutions to this utility model, please refer to [link / reference]. Figure 5The extrusion member includes a pusher plate 6, which is slidably disposed within the cylindrical cavity 302, and the movement of the pusher plate 6 is controlled by a driving moving member disposed on the first connecting plate 3.

[0031] Preferably, the cylindrical cavity 302 is provided with at least one set of limiting grooves 303, and the push plate 6 is provided with a limiting block 601 that slides with the limiting grooves 303.

[0032] Under the constraint of the limiting groove 303 and the limiting block 601, the push plate 6 moves linearly along the axis of the cylindrical cavity 302 within the cylindrical cavity 302, and the rotation of the threaded rod 9 does not affect the push plate 6, and the movement of the threaded rod 9 drives the push plate 6 to move synchronously.

[0033] The driving moving component includes a threaded rod 9 arranged along the axial direction of the push plate 6. The threaded rod 9 passes through the cylindrical cavity 302 and is threadedly connected to the first connecting plate 3. One end of the threaded rod 9 is rotatably connected to the push plate 6, and a knob 8 is fixedly installed on the other end.

[0034] After the tapered part 501 is inserted into the locking hole 402 to initially lock the second connecting plate 4, the connection between the first connecting plate 3 and the second connecting plate 4 is not stable. The first connecting plate 3 can separate from the second connecting plate 4 by moving in the vertical direction. By rotating the control knob 8, the threaded rod 9 is driven to rotate synchronously. At the same time, the threaded rod 9 moves towards the cylindrical cavity 302 along the axis of the cylindrical cavity 302, squeezing the push plate 6. The movement of the push plate 6 can squeeze the spring 7, so that the insertion post 5 can be further inserted into the locking hole 402 to achieve a stable connection between the first connecting plate 3 and the second connecting plate 4. At this time, the first connecting plate 3 and the second connecting plate 4 are completely locked. The connection between the first connecting plate 3 and the second connecting plate 4 is released, and the control knob 8 is rotated in the opposite direction to ensure that the first clamping plate 1 and the second clamping plate 2 can be quickly disassembled and installed without the need for auxiliary tools to control multiple screws to be individually aligned and locked, which effectively improves the installation efficiency of the plate heat exchanger.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
