Description

Technical Field

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

[0002] In industrial production and heat exchange system operation, plate heat exchangers are widely used in chemical, food, HVAC and other fields as a high-efficiency heat exchange equipment. Their core working principle is to achieve heat exchange through the flow of medium between thin plates. However, due to the high humidity and high dust content in the working environment, the side walls of plate heat exchangers are prone to adsorbing water vapor and impurities.

[0003] After prolonged use, water vapor condensation on the surface of the heat exchanger can cause corrosion and aging of the equipment, which not only affects heat exchange efficiency but also shortens the service life of the equipment. At the same time, dust, particulate matter and other impurities in the air adhere to the surface of the heat exchanger, which will further hinder heat transfer and increase energy consumption.

[0004] According to the patent application published on the Internet, a plate heat exchanger with a drying function (authorization announcement number: CN221649285U) is described as including a "plate heat exchanger body, mounting bracket" etc., to achieve the drying function.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This plate heat exchanger with drying function utilizes the plate heat exchanger body and mounting brackets to achieve drying. During use, the heat exchanger dries the front and rear side walls of the plate heat exchanger body through air outlet blocks. However, the air outlets of the air outlet blocks are not opposite to the plate heat exchanger body, resulting in a significant loss of hot air during the drying process, affecting the drying effect. Furthermore, the air entering the fan cannot be filtered, leading to dust accumulation inside the fan, affecting normal operation. Some dust is also transported to the surface of the plate heat exchanger body, affecting the heat exchange effect. Therefore, this heat exchanger needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide a plate heat exchanger with a drying function to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a plate heat exchanger with a drying function, comprising a heat exchanger body, a drying mechanism disposed around the heat exchanger body, and a fixing mechanism disposed around the drying mechanism;

[0009] The drying mechanism includes a support platform, which is fixedly connected to the right side of the heat exchanger body. A fan is fixedly connected to the bottom inner side of the right end of the support platform. A filter box is fixedly connected to the top of the fan. A filter plate is slidably connected inside the filter box. A conveying pipe is fixedly connected to the rear side of the fan.

[0010] Preferably, the support frame is fixedly connected to the rear side of the load-bearing platform, and the fixing frame is fixedly connected to the inner side of the left end of the load-bearing platform, so as to ensure the stability of the T-pipe through the fixing frame.

[0011] Preferably, the connecting arm is fixedly connected to the front side of the heat exchanger body, and the rear side of the drying chamber is provided with an air outlet, which is circular, so that the front and rear sides of the heat exchanger body can be dried through the drying chamber.

[0012] Preferably, the insulation cylinder has a heating chamber inside, and the heating tube is fixedly connected inside the heating chamber to facilitate heating the air passing through the insulation cylinder.

[0013] Preferably, the distributor, drying chamber, and connecting arm are provided in two sets and symmetrically distributed on the left side of the three-way pipe. The two sets of drying chambers are located on the front and rear sides of the heat exchanger body, respectively. The solenoid valves are provided in two sets and symmetrically distributed on the front and rear sides of the top of the three-way pipe. This arrangement allows for drying of the front and rear sides of the heat exchanger body by providing two sets of valves.

[0014] Preferably, the fixing mechanism includes a sealing frame, which is slidably connected to the periphery of the filter box, and a fixing shaft is threadedly connected inside the sealing frame.

[0015] Preferably, the fixed shaft passes through the inside of the filter box, and the sealing frame is slidably connected to the outer rear side of the filter plate, with the inner side of the sealing frame in contact with the rear side of the filter box.

[0016] Compared with the prior art, this utility model provides a plate heat exchanger with a drying function, which has the following beneficial effects:

[0017] 1. This plate heat exchanger with drying function, through its drying mechanism, allows for the drying of the front and rear side walls during operation. External air is drawn in by a fan and filtered through the filter plates in the filter box to remove impurities and dust, preventing them from adhering to the heat exchanger surface and affecting heat exchange efficiency. The filtered air then enters the insulation cylinder, is heated by the heating tubes, and enters the drying chambers located on the front and rear sides of the heat exchanger body via a three-way pipe and a distributor. Finally, the air is blown out from the air outlet on the rear side of the drying chamber. This comprehensive and uniform drying of the front and rear side walls of the heat exchanger body prevents corrosion and aging caused by moisture, extending the service life of the heat exchanger. The two symmetrically distributed drying chambers allow the drying air to act on the heat exchanger from multiple directions, improving the comprehensiveness and efficiency of drying. Two sets of solenoid valves at the top of the three-way pipe allow for individual control of the hot air flow entering the front and rear drying chambers. Users can flexibly adjust the flow according to the moisture level of different parts of the heat exchanger to achieve targeted drying, improving drying accuracy and energy utilization efficiency, and avoiding unnecessary energy waste.

[0018] 2. This plate heat exchanger with drying function, through the set fixing mechanism, makes it very convenient to replace and clean the filter plate when the filter plate is working inside the filter box, as the threaded connection between the sealing frame and the fixing shaft makes the filter plate replacement and cleaning very convenient. When the filter plate needs maintenance, simply unscrew the fixing shaft and slide open the sealing frame to easily remove the filter plate, which greatly reduces the maintenance cost and difficulty of the equipment. At the same time, the sealing frame can seal the gap between the filter plate and the filter box. Attached Figure Description

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a plate heat exchanger with drying function, including a heat exchanger body 1, a drying mechanism 2 arranged around the heat exchanger body 1, and a fixing mechanism 3 arranged around the drying mechanism 2.

[0033] The drying mechanism 2 includes a support platform 21, which is fixedly connected to the right side of the heat exchanger body 1. A fan 22 is fixedly connected to the bottom inner side of the right end of the support platform 21. A filter box 23 is fixedly connected to the top of the fan 22. A filter plate 24 is slidably connected inside the filter box 23. A conveying pipe 25 is fixedly connected to the rear side of the fan 22. An insulation cylinder 26 is fixedly connected to the left side of the conveying pipe 25. A support frame 29 is fixedly connected to the bottom of the insulation cylinder 26. A heating pipe 28 is fixedly connected inside the insulation cylinder 26. A three-way pipe 27 is fixedly connected to the left side of the insulation cylinder 26. A fixing frame 291 is fixedly connected to the outside of the three-way pipe 27. A solenoid valve 292 is fixedly connected to the top of the three-way pipe 27. A distributor 293 is fixedly connected to the left side of the three-way pipe 27. A drying chamber 294 is fixedly connected to the left side of the distributor 293. Connecting arms 295 are fixedly connected to the left and right sides of the drying chamber 294.

[0034] The support frame 29 is fixedly connected to the rear side of the load-bearing platform 21, and the fixing frame 291 is fixedly connected to the inner side of the left end of the load-bearing platform 21, so as to ensure the stability of the tee pipe 27 through the fixing frame 291.

[0035] The connecting arm 295 is fixedly connected to the front side of the heat exchanger body 1. The drying box 294 has an air outlet on the rear side, and the air outlet is circular, so that the front and rear sides of the heat exchanger body 1 can be dried through the drying box 294.

[0036] The insulation cylinder 26 has a heating chamber inside, and the heating tube 28 is fixedly connected inside the heating chamber, so that the air passing through the insulation cylinder 26 can be heated through the heating tube 28.

[0037] Two sets of distributors 293, drying chambers 294 and connecting arms 295 are provided and symmetrically distributed on the left side of the three-way pipe 27. The two sets of drying chambers 294 are located on the front and rear sides of the heat exchanger body 1, respectively. Two sets of solenoid valves 292 are provided and symmetrically distributed on the front and rear sides of the top of the three-way pipe 27, so that the front and rear sides of the heat exchanger body 1 can be dried by setting two sets.

[0038] Example 2

[0039] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a sealing frame 31, which is slidably connected to the periphery of the filter box 23, and a fixing shaft 32 is threadedly connected inside the sealing frame 31.

[0040] The fixed shaft 32 passes through the inside of the filter box 23, and the sealing frame 31 is slidably connected to the rear periphery of the filter plate 24. The inner side of the sealing frame 31 is in contact with the rear side of the filter box 23, which facilitates the stability of the filter plate 24 through the sealing frame 31, and can also seal the gap between the filter plate 24 and the filter box 23.

[0041] In actual operation, when this device is in use, when the plate heat exchanger needs to dry the front and rear side walls, firstly, the filter plate 24 is slidably connected to the inside of the filter box 23, and at the same time, the sealing frame 31 is slidably connected to the outside of the filter box 23 and to the rear outer side of the filter plate 24, so as to seal the gap between the filter plate 24 and the filter box 23, and the sealing frame 31 is fixed by the fixing shaft 32;

[0042] Simultaneously, external power supply equipment powers the fan 22 and heating tube 28, enabling them to operate. After the fan 22 introduces external air, it is filtered by the filter plate 24 in the filter box 23 to remove impurities and dust from the air, preventing impurities from adhering to the surface of the heat exchanger and affecting the heat exchange efficiency. The filtered air enters the insulation cylinder 26 and is heated into hot air by the heating tube 28. The hot air enters the drying chamber 294 located on the front and rear sides of the heat exchanger body 1 through the three-way pipe 27 and the distributor 293, and is finally blown out from the air outlet on the rear side of the drying chamber 294. This can comprehensively and evenly dry the front and rear side walls of the heat exchanger body 1, preventing equipment corrosion and aging caused by moisture and extending the service life of the heat exchanger. The two sets of drying chambers 294 are symmetrically distributed, allowing the drying air to act on the heat exchanger from multiple directions, improving the comprehensiveness and efficiency of drying.

[0043] The two sets of solenoid valves 292 installed at the top of the three-way pipe 27 can individually control the flow rate of hot air entering the front and rear drying chambers 294. Users can flexibly adjust the flow rate according to the moisture content of different parts of the heat exchanger to achieve targeted drying, improve the accuracy of drying and energy utilization efficiency, and avoid unnecessary energy waste.

[0044] The support frame 29 supports the insulation cylinder 26, the fixing frame 291 fixes the three-way pipe 27, and the load-bearing platform 21 supports the fan 22, filter box 23 and other components. All of these ensure that the drying mechanism 2 will not be displaced or loosened due to vibration or other factors during operation, thus ensuring the stable progress of the drying process.

[0045] When using the filter plate 24, the staff needs to disassemble and clean it regularly to ensure the filtration quality. Simply unscrew the fixing shaft 32 and slide open the sealing frame 31 to easily remove the filter plate 24, which greatly reduces the maintenance cost and difficulty of the equipment.
