[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a cleaning device for heat exchangers with a fixed structure, comprising a cleaning tank 1; a fixing mechanism, located on the left and right sides of the heat exchanger body 3, which limits the position of the heat exchanger body 3 before cleaning, ensuring that the heat exchanger body 3 does not move during cleaning and improving the cleaning effect; a drying mechanism, located inside the cleaning tank 1, which heats the interior of the cleaning tank 1 and uses an electric fan 16 to accelerate the circulation of hot air, thus quickly drying the heat exchanger body 3; and a water circulation mechanism, located in the cleaning tank 1. The front and rear exterior sections can filter and purify the cleaned wastewater, allowing for its recycling and significantly conserving water resources. First, the rotating plate 2 is opened, then the heat exchanger body 3 is placed inside the cleaning tank 1. The rotating plate 2 is then closed. At this point, the fixing plate 4 is symmetrically positioned on the outside of the heat exchanger body 3. A rubber pad 5 is installed inside the fixing plate 4. Opening the electric telescopic rod 6 allows the output end of the electric telescopic rod 6 to push the fixing plate 4 and rubber pad 5 inwards, ensuring a tight fit between the fixing plate 4 and the heat exchanger body 3, thus fixing the position of the heat exchanger body 3. The rubber pad 5 installed inside the fixing plate 4 reduces subsequent impact on the heat exchanger. During the rinsing of the heat exchanger body 3, the heat exchanger body 3 is subjected to vibration damage. After the position of the heat exchanger body 3 is fixed, water and cleaning solution are poured into the water tank 11. Then, the water is transmitted to the support frame 13 through the inlet pipe 12 connected to the inside of the water tank 11, and then sprayed out by the rinsing head 14 installed on the inside of the support frame 13. The heat exchanger body 3 can be thoroughly rinsed from the front and rear sides. The rinsed water can enter the drain pipe 8 through the drain trough 7 opened inside the bottom of the cleaning tank 1. The drain pipe 8 is fixedly connected to the outside of the water purifier 9, and the outside of the water purifier 9 is connected to the water pump 10. The water pump 10 is connected to the water tank 11. When the pump is turned on... Pump 10 pumps the cleaned wastewater through drain pipe 8 into the water purifier 9. The water purifier 9 filters and purifies the wastewater, and the filtered water is stored in water tank 11 to prepare for the next cleaning. After the heat exchanger body 3 is cleaned, the heating wire 17 installed on the inner wall of the cleaning chamber 1 can be turned on. The heating wire 17 generates heat, which raises the temperature inside the cleaning chamber 1. Then, the electric fan 16 installed inside the top cover 15 installed on the top of the cleaning chamber 1 is turned on. The electric fan 16 accelerates the flow of hot air, which makes the heat exchanger body 3 dry quickly. After the heat exchanger body 3 is dried, the rotating plate 2 can be opened to remove it.

[0032] Existing cleaning equipment can cause positional shifts in the heat exchanger body 3 when subjected to strong water impact cleaning, leading to incomplete cleaning. Therefore, this embodiment addresses this issue with the following technical solution: Figure 4 , Figure 5 and Figure 6As shown, the fixing mechanism includes fixing plates 4 set on the left and right sides of the heat exchanger body 3. Rubber pads 5 are installed inside the fixing plates 4, and electric telescopic rods 6 are fixedly connected to the outside of the fixing plates 4. When the electric telescopic rods 6 are opened, the output end of the electric telescopic rods 6 can push the fixing plates 4 and the rubber pads 5 inward, so that the fixing plates 4 and the heat exchanger body 3 are firmly attached together, limiting the position of the heat exchanger body 3. This ensures that the heat exchanger body 3 will not move under strong water flushing, and the setting of the fixing plates 4 can reduce the impact and vibration damage to the heat exchanger body 3.

[0033] Example 2: In existing cleaning equipment, if the heat exchanger body 3 is not dried after cleaning, it will cause rust to appear on the heat exchanger body 3, which will greatly reduce its service life. Therefore, this example uses the following technical solution, such as... Figure 3 , Figure 4 and Figure 5 As shown, the drying mechanism includes an electric heating wire 17 installed on the inner wall of the cleaning chamber 1. After the heat exchanger body 3 is rinsed, some water stains will remain. When the electric heating wire 17 installed on the inner wall of the cleaning chamber 1 is turned on, the electric heating wire 17 will generate heat to heat the inside of the cleaning chamber 1. At the same time, a top cover 15 is installed on the top of the cleaning chamber 1, and electric fans 16 are installed at equal intervals inside the top cover 15. Turning on the electric fans 16 can accelerate the circulation of hot air, so that the heat exchanger body 3 can be dried quickly.

[0034] Example 3: Existing cleaning equipment achieves wastewater recycling through multiple filtration processes. However, this involves high costs for filter materials during these multiple filtrations. Therefore, this example addresses this issue by employing the following technical solution: Figure 2 , Figure 3 and Figure 6 As shown, the water recycling mechanism includes a drain trough 7 located at the bottom of the cleaning tank 1. A drain pipe 8 is installed below the drain trough 7, and a water purifier 9 is fixedly connected to the outside of the drain pipe 8. A water pump 10 is installed on the outside of the water purifier 9. When the water pump 10 is turned on, wastewater can be pumped. That is, the wastewater discharged from the cleaning tank 1 will enter the interior of the water purifier 9 through the drain pipe 8. The water purifier 9 will filter and purify the wastewater. The purified water will enter the interior of the water tank 11 for storage. Since the inside of the water tank 11 is connected to the inlet pipe 12, and the inlet pipe 12 is connected to the support frame 13, when the water enters the interior of the water tank 11, cleaning liquid can be poured into the interior of the water tank 11. Then the cleaning water is transferred to the interior of the inlet pipe 12 and then enters the support frame 13. It is sprayed out by the flushing heads 14 installed at equal intervals on the inside of the support frame 13. Furthermore, the flushing heads 14 are symmetrically arranged on the outside of the heat exchanger body 3, so that the heat exchanger body 3 can be thoroughly flushed.

All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
