Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a mobile heat exchanger cleaning device. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. In industrial production, heat exchangers are crucial heat exchange equipment, and their performance directly affects the efficiency of the entire production system. However, due to long-term operation and the influence of the working environment, dirt and grime easily accumulate on heat exchangers, leading to a decrease in heat exchange efficiency and even endangering equipment safety. Therefore, regular cleaning of heat exchangers is a necessary maintenance measure.

[0003] The cleaning process requires a large amount of water to flush out the dirt inside the heat exchanger. However, this wastewater is often discharged directly without treatment, resulting in a huge waste of precious water resources. If the harmful substances in the cleaning wastewater are discharged into the environment without proper treatment, they will pollute natural water bodies and ecosystems, affecting environmental quality and ecological balance.

[0004] Based on this, the present invention proposes a mobile heat exchanger cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the deficiencies in the existing technology by proposing a mobile heat exchanger cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mobile heat exchanger cleaning device includes a cleaning platform with a clamping assembly mounted on its top. Multiple drainage channels are laterally formed on the top of the cleaning platform. A first water collection tank and a second water collection tank are formed inside the cleaning platform, separated by a partition plate. A water guide plate is installed between the first water collection tank and the multiple drainage channels. A first connecting pipe is installed between the first water collection tank and the second water collection tank, and a first water pump is installed on the first connecting pipe.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0028] Reference Figure 1-6 A mobile heat exchanger cleaning device includes a cleaning platform 1. A clamping assembly 2 is installed on the top of the cleaning platform 1 to fix the heat exchanger, ensuring its stability during cleaning and preventing movement or tilting. Multiple drainage channels 3 are horizontally formed on the top of the cleaning platform 1 to collect wastewater generated during cleaning. A first water collection tank 4 and a second water collection tank 5 are formed inside the cleaning platform 1, separated by a partition plate 6. A water guide plate 7 is installed between the first water collection tank 4 and the multiple drainage channels 3. The water guide plate 7 ensures that wastewater can flow smoothly from the drainage channels 3 into the first water collection tank 4, preventing wastewater accumulation on the cleaning platform 1. The first water collection tank 4 is used to collect wastewater flowing in from the drainage channels 3. The water undergoes sedimentation treatment. A first connecting pipe 8 is installed between the first water collection tank 4 and the second water collection tank 5. A first water pump 9 is installed on the first connecting pipe 8. The first water pump 9 pumps the pre-treated water in the first water collection tank 4 into the second water collection tank 5 through the first connecting pipe 8. An installation plate 10 is slidably installed on the top of the cleaning platform 1. Multiple cleaning nozzles 11 are evenly installed on the inner side of the installation plate 10 to clean different parts of the heat exchanger evenly. A second connecting pipe 12 is installed between the second water collection tank 5 and the multiple cleaning nozzles 11. A second water pump 13 is installed on the second connecting pipe 12. The second water pump 13 delivers the water that has undergone secondary treatment in the second water collection tank 5 to the cleaning nozzles 11 through the second connecting pipe 12.

[0029] The first collection tank 4 serves as the wastewater collection and preliminary treatment area. Its core function is to receive wastewater flowing in from the drainage trough 3 at the top of the cleaning platform 1. By adding an appropriate amount of flocculant and utilizing a natural sedimentation filtration mechanism, it effectively removes large particulate impurities from the wastewater. The second collection tank 5 plays the role of the secondary wastewater treatment area. Its design aims to further purify the water flowing in from the first collection tank 4. According to the wastewater composition, appropriate chemical agents, such as coagulants, flocculants, and oxidants, are added to neutralize, precipitate, or oxidize and remove pollutants from the wastewater. The first water pump 9 pumps the pre-treated water from the first collection tank 4 through the first connecting pipe 8 and sends it to the second collection tank 5. The second water pump 13 then transports the secondary-treated water from the second collection tank 5 to the cleaning nozzle 11 through the second connecting pipe 12 for cleaning the heat exchanger. This not only saves water resources but also reduces the environmental pollution caused by wastewater discharge.

[0030] The clamping assembly 2 includes a bidirectional lead screw 201, which is rotatably mounted on the cleaning table 1. Both ends of the bidirectional lead screw 201 are threaded with clamping plates 202, which slide at the drain trough 3, enabling stable clamping of the heat exchanger. Regardless of the size of the heat exchanger, the distance between the clamping plates 202 can be adjusted to accommodate different sizes, ensuring that the heat exchanger will not move or tilt during cleaning. A first motor 203 is fixedly mounted at the end of the cleaning table 1, and its output end is fixedly connected to the bidirectional lead screw 201. When the first motor 203 starts, the rotation of its output shaft drives the bidirectional lead screw 201 to rotate synchronously. By controlling the rotation direction and speed of the first motor 203, the distance between the two clamping plates 202 can be precisely adjusted, thus enabling clamping of heat exchangers of different sizes. Operators only need to start the motor and set the rotation direction and speed to easily complete the clamping of the heat exchanger, greatly improving cleaning efficiency.

[0031] Multiple water guide channels 14 are longitudinally arranged on the top of the cleaning station 1. The ends of the water guide channels 14 are connected to the drainage channels 3 to guide the wastewater generated during the cleaning process, ensuring that the wastewater can flow smoothly into the drainage channels 3 for subsequent wastewater treatment or discharge. A drawer 15 is slidably installed on the cleaning station 1. The drawer 15 is located between the water guide plate 7 and the multiple drainage channels 3. The bottom of the drawer 15 has multiple filter holes evenly distributed. These filter holes allow wastewater to pass through, but at the same time can intercept larger impurities and smaller parts on the equipment, thereby reducing the burden of subsequent wastewater treatment. Through the setting of the water guide channels 14, the wastewater generated during the cleaning process can be quickly and effectively collected and guided to the drainage channels 3, avoiding the accumulation and leakage of wastewater. This not only improves cleaning efficiency, but also ensures a clean and safe working environment. The sliding installation design of the drawer 15 not only makes it easy for operators to pull out and push in the drawer 15 when needed for cleaning impurities and recycling smaller parts, but also ensures the stability and reliability of the cleaning station 1 during long-term operation.

[0032] Mounting components 16 are installed at both the front and rear ends of the cleaning table 1. The two ends of the mounting plate 10 are slidably mounted on the mounting components 16, ensuring smooth linear movement of the mounting plate 10 along the mounting components 16. A second motor 17 is fixedly mounted on the outer wall of one of the mounting components 16, serving as a power source to power the entire drive mechanism. A lead screw 18 is rotatably mounted inside the motor 16, and the output end of the second motor 17 is fixedly connected to the lead screw 18. When the second motor 17 starts, its rotational motion is converted into linear motion of the lead screw 18. A guide rod 19 is fixedly mounted inside the other mounting component 16, providing guidance and support. One end of the mounting plate 10 is threaded onto the lead screw 18, and the other end is slidably mounted on the guide rod 19. Through the coordinated use of the second motor 17 and the lead screw 18, efficient driving and adjustment of the mounting plate 10 are achieved. This design not only improves the automation level of the cleaning table 1 but also makes operation simpler and faster.

[0033] Two inlet pipes 20 and two outlet pipes 21 are fixedly installed at the rear end of the cleaning station 1. The two inlet pipes 20 and the two outlet pipes 21 are connected to the first water collection tank 4 and the second water collection tank 5, respectively. The inlet pipes 20 are located above the outlet pipes 21. Each of the two inlet pipes 20 and the two outlet pipes 21 is threaded with a cap 22. The two inlet pipes 20 are used to add water and treatment agent required for cleaning into the cleaning station 1. By controlling the inlet water flow rate and speed, the liquid level and treatment agent concentration in the cleaning station 1 can be precisely adjusted to meet different cleaning needs. The outlet pipes 21 are used to discharge wastewater and impurities generated during the cleaning process to prevent accumulation in the cleaning station 1. The installation of the caps 22 helps prevent external pollutants from entering the piping system, protecting the internal environment of the cleaning station 1 from pollution. At the same time, the caps 22 also reduce water evaporation and heat loss, helping to maintain stable temperature and humidity inside the cleaning station 1.

[0034] Four casters 23 are evenly installed on the bottom of the cleaning station 1, and a handle 24 is fixedly installed on the cleaning station 1. Two water level sensors 25 are fixedly installed inside the cleaning station 1, and the two water level sensors 25 are respectively installed in the first water collection tank 4 and the second water collection tank 5. The casters 23 can significantly improve the mobility and flexibility of the cleaning station 1, allowing it to move freely in narrow or complex environments and facilitating movement between different work locations. Through the handle 24, the operator can easily push or pull the cleaning station 1 to quickly adjust its position. The integration of the water level sensors 25 enables the cleaning station 1 to monitor the water level in the tank in real time and make precise control as needed, avoiding the impact of excessively high or low water levels on the cleaning effect and improving the cleaning quality.

[0035] Working principle: When using this device, the heat exchanger is placed on the cleaning platform 1, aligned with the drain tank 3. The first motor 203 is started, and the distance between the clamping plates 202 is adjusted by the bidirectional lead screw 201 to clamp the heat exchanger and ensure it remains stable. The second motor 17 is started, and through the cooperation of the lead screw 18 and the guide rod 19, the mounting plate 10 is driven to slide along the mounting part 16, so that the cleaning nozzles 11 are aimed at different parts of the heat exchanger. The second water pump 13 delivers the secondary-treated water or cleaning solution from the second water collection tank 5 to the cleaning nozzles 11 through the second connecting pipe 12 to clean the heat exchanger. Wastewater generated during the cleaning process flows into the first drain tank 3. The first water collection tank 4 performs preliminary treatment. The first water pump 9 pumps the pre-treated water from the first water collection tank 4 to the second water collection tank 5 through the first connecting pipe 8 for secondary treatment. The water level sensor 25 monitors the water level in the first water collection tank 4 and the second water collection tank 5 in real time. As needed, the water level is controlled by adjusting the flow rate of the inlet pipe 20 or the discharge of the outlet pipe 21. After cleaning, the cover 22 of the outlet pipe 21 is opened to discharge the treated wastewater in the second water collection tank 5. If necessary, the wastewater in the first water collection tank 4 can also be discharged. The drawer 15 is pulled out to clean the larger impurities and smaller parts on the equipment. After cleaning, the drawer 15 is pushed back into place.
