Description

Technical Field

[0001] The invention relates to the field of heat exchangers, and in particular to a universal high thermal efficiency plate heat exchanger. Background Art

[0002] After long-term use, scale is likely to accumulate between adjacent plates, which not only affects the heat exchange efficiency but may also damage the equipment. Traditional cleaning methods usually require all heat exchange plates to be completely removed from the heat exchanger. However, due to the adhesion of scale, the separation between adjacent plates becomes extremely difficult, and it is difficult to control the strength during manual operation, which is not only easy to scratch the hands, but may also damage the heat exchange plates due to excessive force.

[0003] The removed heat exchanger plates need to be thoroughly cleaned with a high-pressure water gun. During this process, the staff also needs to manually flip the plates to ensure that both sides are fully cleaned. After cleaning, the plates need to be reinstalled back into the heat exchanger piece by piece, which is a tedious and time-consuming process.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figures 1 to 7, a universal high thermal efficiency plate heat exchanger. This heat exchanger includes a fixed pressing plate 1, which is characterized in that an upper guide rail 2 and a lower guide rail 3 are firmly fixed at the upper and lower ends of one side. The two guide rails are tightly combined with a connecting frame 4 at the end away from the fixed pressing plate 1. Between the connecting frame 4 and the fixed pressing plate 1, a movable pressing plate 5 is cleverly installed so that it can be easily adjusted when needed.

[0030] Furthermore, a number of heat exchange plates 6 are neatly arranged between the movable clamping plate 5 and the fixed clamping plate 1. These heat exchange plates 6 are firmly fixed between the movable clamping plate 5 and the fixed clamping plate 1 through a set of precise bolt assemblies C. It is worth mentioning that this set of bolt assemblies C consists of bolt rods 18 and matching nuts 19, which are tightly connected together through threads. Both side walls of the fixed clamping plate 1 and the movable clamping plate 5 are provided with mounting grooves (respectively the first mounting groove and the second mounting groove) specifically used to accommodate and position these bolt rods 18, ensuring the stability and reliability of the entire structure.

[0031] In addition, a gantry 7 is slidably connected to the upper guide rail 2 and the lower guide rail 3. Specially designed separation components D are symmetrically installed on both sides of the gantry 7. The main task of these components is to help separate the heat exchange plate 6 when necessary. The structure of the separation component D is quite sophisticated, including a cylinder 8 fixed to the side wall of the gantry 7, and a fixed sleeve 9 is connected to the output end of the cylinder 8. A sliding seat 10 is embedded and slidably connected at one end of the fixed sleeve 9, and a high-precision pressure sensor 11 is installed inside the fixed sleeve 9.

[0032] The input end of the pressure sensor 11 is connected to the slide 10 through a spring 12. When the slide 10 is subjected to external force, it will compress or stretch the spring 12, thereby changing the reading of the pressure sensor 11. A driving plate 13 is fixedly connected to the other side of the slide 10, and the end of the driving plate 13 is designed with an inclined surface A that can perfectly contact the heat exchange plate 6. At the same time, a blocking surface B is also provided on the side wall of the driving plate 13, and the blocking surface B can drive the heat exchange plate 6 to make necessary movements when necessary.

[0033] It is worth mentioning that the edges between adjacent heat exchange plates 6 are carefully designed to leave a certain gap. This gap not only allows the end of the drive plate 13 to easily enter, but also plays a key role in the cleaning process. After the heat exchange plate 6 has been used for a period of time, scale will accumulate on its surface and in the gap, seriously affecting the heat exchange efficiency. At this time, through this carefully designed separation and drive system, the heat exchange plate 6 can be easily separated and cleaned.

[0034] The entire cleaning process is controlled by a set of efficient driving devices 14. The driving device 14 includes a mounting plate 15 fixed on the top of the fixed pressing plate 1, and a driving motor 16 installed on one side of the mounting plate 15. The output shaft of the driving motor 16 is closely connected to a screw rod 17, and a threaded hole is provided at the top of the door frame 7, and the threaded hole is closely connected to the screw rod 17 through threads. When the driving motor 16 is started, it drives the screw rod 17 to rotate, thereby driving the door frame 7 to slide accurately along the upper guide rail 2 and the lower guide rail 3.

[0035] In terms of circuit control, the pressure sensor 11, the controller 23, the cylinder 8 and the drive motor 16 form a sophisticated control system. The pressure sensor 11 monitors the pressure value in real time and transmits the data to the controller 23. The controller 23 determines the position and state of the drive plate 13 based on the received data, and controls the extension of the cylinder 8 and the start, stop and turn of the drive motor 16 accordingly. This system not only ensures that the heat exchange plate 6 can be separated and cleaned accurately and efficiently, but also greatly improves the service life and heat exchange efficiency of the entire heat exchanger.

[0036] In addition, both ends of the movable pressing plate 5 are designed to be slidably connected with the upper guide rail 2 and the lower guide rail 3, making adjustment and maintenance more convenient. The end of the screw rod 17 away from the motor is rotatably connected with the connecting frame 4, ensuring that the door frame 7 can slide smoothly and accurately. At the same time, the sealing gasket 20 installed on the heat exchange plate 6 effectively prevents the liquid from flowing out from between adjacent heat exchange plates 6, ensuring the safety and efficiency of the heat exchange process.

[0037] Grooves 24 are cleverly provided at the upper and lower ends of the heat exchange plate 6, which perfectly match the upper guide rail 2 and the lower guide rail 3, further enhancing the stability and reliability of the heat exchange plate 6. The ear plates 21 symmetrically installed on the top of the movable clamping plate 5 and the driving wheel 22 rotatably connected inside enable the movable clamping plate 5 to move easily on the upper guide rail 2, greatly simplifying the maintenance and adjustment process.

[0038] Finally, the bolt rods 18 are evenly distributed on both sides of the heat exchange plate 6, ensuring the stability and uniform force of the entire heat exchanger structure. The controller 23 fixed on the outside of the clamping plate 1 is electrically connected to the pressure sensor 11 and the cylinder 8, realizing precise control of the entire system. This efficient and universal plate heat exchanger is not only exquisitely designed and stable in structure, but also has excellent heat exchange efficiency and easy maintenance. It is undoubtedly one of the indispensable and important equipment in the modern industrial field.

[0039] It should be emphasized that the water inlet and outlet and the specific liquid flow passage of the heat exchange plate 6 are common knowledge among those skilled in the art and are not described in this patent document.

[0040] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
