Description

Technical Field

[0001] The present application relates to the technical field of air-to-air plate heat exchangers, and in particular to an air filtering structure of an air-to-air plate heat exchanger. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the footprint is one-third of that of the tube heat exchanger. The heat recovery rate can be as high as more than 90%;

[0003] With respect to the above-mentioned related technologies, the inventors believe that in the existing air-to-air plate heat exchanger technology, the design of the air filter structure usually relies on the traditional fixed or screw-fixed installation method, which has exposed some problems in long-term use, such as low installation efficiency, difficult disassembly and maintenance, poor sealing performance, etc. These problems not only affect the operating efficiency of the heat exchanger, but also increase the maintenance cost and downtime of the equipment;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problem that in the existing air-to-air plate heat exchanger technology, the design of the air filter structure usually relies on traditional fixed or screw-fixed installation methods, which have exposed some problems in long-term use, such as low installation efficiency, difficult disassembly and maintenance, poor sealing performance, etc. These problems not only affect the operating efficiency of the heat exchanger, but also increase the maintenance cost and downtime of the equipment. The present application provides an air filter structure for an air-to-air plate heat exchanger.

[0006] The air filtering structure of an air-to-air plate heat exchanger provided in the present application adopts the following technical solution:

[0007] A gas filtering structure of an air-to-air plate heat exchanger comprises a shell, a rectangular cavity is arranged in the shell, a limit cavity is opened on the right inner wall of the shell, a second magnetic block is fixedly connected to the inner wall of the limit cavity, a motor is installed at the lower end of the shell, a filter plate is arranged on one side of the shell, a limit block is fixedly connected to one side of the filter plate, a first magnetic block is fixedly connected to the limit block, and a mounting mechanism for the filter plate is arranged in the shell.

[0008] Preferably, the mounting mechanism includes two slide grooves opened in the shell, and a threaded rod is rotatably connected between the upper and lower inner walls of the two slide grooves. The end of the output shaft of the motor extends into the slide groove located on the left side and is fixedly connected to the lower end of the threaded rod therein.

[0009] Preferably, the two threaded rods are fixedly connected with a synchronous transmission wheel, the two synchronous transmission wheels are connected through a synchronous transmission belt, and the two threaded rods are threadedly connected with a slide plate.

[0010] Preferably, the two slide plates are slidably connected to the left and right inner walls of the corresponding slide grooves, and the upper ends of the two slide plates are fixedly connected with limit rods that match the limit holes.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. Start the motor. Since the threaded rods are connected through a synchronous transmission belt, the rotation of the threaded rod on the left will drive the threaded rod on the right to rotate synchronously. The rotation of the two threaded rods causes the two slides to drive the corresponding limit rods to move upward, so that multiple limit rods enter the corresponding limit holes to complete the installation of the filter plate. When the filter plate needs to be disassembled, the reverse start motor causes multiple limit rods to leave the corresponding limit holes to complete the disassembly, thus realizing the rapid installation and disassembly of the filter plate;

[0014] 2. Insert the limit block of the filter plate into the limit cavity. At this time, due to the attraction of the first magnetic block and the second magnetic block, the limit block will be attracted into the limit cavity, thereby limiting the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses an air filter structure of an air-to-air plate heat exchanger. Figure 1-2 A gas filtering structure of an air-to-air plate heat exchanger comprises a shell 1, a rectangular cavity 10 is arranged in the shell 1, a limiting cavity 8 is opened on the right inner wall of the shell 1, a second magnetic block 9 is fixedly connected to the inner wall of the limiting cavity 8, a motor 3 is installed at the lower end of the shell 1, a filter plate 4 is arranged on one side of the shell 1, a limiting block 6 is fixedly connected to one side of the filter plate 4, a first magnetic block 7 is fixedly connected to the limiting block 6, and a mounting mechanism for the filter plate 4 is arranged in the shell 1.

[0021] The limiting block 6 of the filter plate 4 is inserted into the limiting cavity 8. At this time, due to the attraction of the first magnetic block 7 and the second magnetic block 9, the limiting block 6 will be attracted into the limiting cavity 8, thereby limiting the filter plate 4.

[0022] Reference Figure 2-3 The mounting mechanism includes two slide grooves 12 opened in the shell 1, and threaded rods 14 are rotatably connected between the upper and lower inner walls of the two slide grooves 12. The output shaft end of the motor 3 extends into the slide groove 12 located on the left side and is fixedly connected to the lower end of the threaded rod 14 therein. Synchronous transmission wheels are fixedly connected to the two threaded rods 14, and the two synchronous transmission wheels are connected through synchronous transmission belts. Slide plates 11 are threadedly connected to the two threaded rods 14. The two slide plates 11 are slidably connected to the left and right inner walls of the corresponding slide grooves 12, and the upper ends of the two slide plates 11 are fixedly connected to limit rods 13 that match the limit holes 5.

[0023] Start the motor 3. Since the threaded rod 14 is connected through a synchronous transmission belt, the rotation of the threaded rod 14 on the left will drive the threaded rod 14 on the right to rotate synchronously. The rotation of the two threaded rods 14 causes the two slides 11 to drive the corresponding limit rods 13 to move upward, so that multiple limit rods 13 enter the corresponding limit holes 5, and the installation of the filter plate 4 is completed. When the filter plate 4 needs to be disassembled, the reverse starting motor 3 makes the multiple limit rods 13 leave the corresponding limit holes 5, and the disassembly is completed, thereby realizing the rapid installation and disassembly of the filter plate 4.

[0024] Reference Figure 1 A controller 2 is installed on the front side of the shell 1, and the controller 2 is connected to the motor 3 by signal. A plurality of openings are opened on the front and rear inner walls of the shell 1, and an activated carbon plate is placed in the filter plate 4. The adjacent surfaces of the first magnetic block 7 and the second magnetic block 9 are anisotropically attracted to each other.

[0025] The implementation principle of the air filter structure of the air-to-air plate heat exchanger of the present application embodiment is as follows: when the filter plate 4 needs to be installed, the limit block 6 of the filter plate 4 is inserted into the limit cavity 8. At this time, due to the attraction of the first magnetic block 7 and the second magnetic block 9, the limit block 6 is attracted into the limit cavity 8, thereby limiting the filter plate 4;

[0026] At this time, the motor 3 is started through the controller 2. Since the threaded rod 14 is connected through the synchronous transmission belt, the rotation of the threaded rod 14 on the left will drive the threaded rod 14 on the right to rotate synchronously. The rotation of the two threaded rods 14 causes the two slides 11 to drive the corresponding limit rods 13 to move upward, so that multiple limit rods 13 enter the corresponding limit holes 5, and the installation of the filter plate 4 is completed. When the filter plate 4 needs to be disassembled, the motor 3 is started in the reverse direction to make the multiple limit rods 13 leave the corresponding limit holes 5, and the disassembly can be completed, thereby realizing the rapid installation and disassembly of the filter plate 4.
