Description

Technical Field

[0001] The utility model relates to the field of plate heat exchangers, in particular to a plate heat exchange unit which is easy to clean and prevents clogging. Background Art

[0002] A plate heat exchanger is a type of heat exchanger characterized by the use of a plate heat exchanger. Under the same pressure loss conditions, its heat transfer coefficient is 3-5 times higher than that of a tube heat exchanger, and its floor space is one-third of that of a tube heat exchanger. Its heat recovery rate can be as high as over 90%. When existing plate heat exchangers are working, the heat exchange medium contains particulate matter, impurities, suspended matter or sediment. These substances will be deposited in the plate flow channel, gradually forming blockage or fouling, affecting the heat exchange efficiency. In addition, when the plate heat exchanger is working, heat cannot be transferred from one fluid to another in a timely and effective manner, and accumulates inside the heat exchanger, which will cause the internal temperature of the heat exchanger to rise. Long-term high-temperature operation will cause thermal stress fatigue in the material, and even cause plate deformation, cracking or seal failure.

[0003] Therefore, it is necessary to provide a new plate heat exchanger unit that is easy to clean and prevents clogging to solve the above technical problems. Utility Model Content

The top of the water outlet of the inlet and outlet water pipe 2 is fixedly connected with a cleaning pipe 3. The left side of the water inlet of the inlet and outlet water pipe 2 is provided with a first empty groove 10. The first filter plate 6 is slidably connected inside the first empty groove 10. The top of the water inlet of the inlet and outlet water pipe 2 is fixedly connected with the cleaning pipe 3. A second slot 13 is provided on both sides, and a return spring 11 is fixedly connected to the left side of the second slot 13 through the inlet and outlet pipes 2. The other end of the return spring 11 is fixedly connected to a slider 12, and the right side of the top of the slider 12 is set as an inclined surface. Disassembly buttons 9 are slidably connected to both sides of the top of the water inlet of the inlet and outlet pipes 2. The front and rear of the disassembly button 9 are fixedly connected to the limit block 14. The middle of the top of the first filter plate 6 is fixedly connected to the handle 7. The diagonal parts of the upper side of the first filter plate 6 are provided with fixing holes 8. The slider 12 is slidably connected inside the fixing hole 8. The first filter plate 6 The bottom is fixedly connected with a bottom plate 20, and a placement groove 15 is provided at the bottom of the first empty groove 10 through the water inlet of the inlet and outlet pipes 2. The bottom plate 20 is slidably connected inside the placement groove 15. Before the plate heat exchanger is used, the first filter plate 6 is placed inside the first empty groove 10, and then the bottom plate 20 is placed inside the placement groove 15. When the second empty groove 13 is flush with the fixing hole 8, the slider 12 enters the fixing hole 8 under the elastic force of the return spring 11. Under the limit of the bottom plate 20 and the slider 12, the first filter plate 6 is fixed inside the inlet and outlet pipes 2, so that when When the plate heat exchanger unit is in use, the heat exchange medium entering the plate heat exchanger 1 is filtered through the first filter plate 6 to intercept and remove particulate matter and impurities in the medium to prevent them from entering the heat exchanger and causing blockage. By pressing the disassembly button 9, the slider 12 moves toward the second slot 13 and compresses the return spring 11, so that the slider 12 leaves the fixing hole 8. Then, the first filter plate 6 is pulled out through the handle 7 to facilitate cleaning of the first filter plate 6 and prevent the sieve holes on the first filter plate 6 from being blocked and affecting the use of the device.

When the second empty slot 13 is flush with the fixing hole 8, the slider 12 is made to enter the fixing hole 8 under the elastic force of the return spring 11. Under the limit of the bottom plate 20 and the slider 12, the first filter plate 6 is fixed inside the inlet and outlet pipes 2. When the plate heat exchanger unit is used, the heat exchange medium entering the plate heat exchanger 1 is filtered through the first filter plate 6 to intercept and remove particulate matter and impurities in the medium to prevent them from entering the heat exchanger and causing clogging. By pressing the disassembly button 9, the slider 12 is moved to the second empty slot 13 and the return spring is released. The spring 11 is compressed, so that the slider 12 leaves the inside of the fixing hole 8, and then the first filter plate 6 is pulled out by the handle 7, which is convenient for cleaning the first filter plate 6 to prevent the sieve holes on the first filter plate 6 from being blocked and affecting the use of the device. The motor 17 is started by remote control to drive the fan 19 to rotate, so that the external air is filtered through the second filter plate 16 and enters the plate heat exchanger 1 to dissipate heat and cool the internal metal plates to prevent the plate heat exchanger 1 from overheating and causing damage. At the same time, when the plate heat exchanger unit is not in use, the water inlet and outlet pipes 2 are closed, and the water pump 4 is started by remote control to draw the cleaning water into the plate heat exchanger 1 through the cleaning pipe 3, and the plate heat exchanger 1 is backflushed to clean the inside of the plate heat exchanger 1, again preventing the inside of the plate heat exchanger 1 from being blocked.
