[0002] Hydrocarbon vacuum cleaners utilize hydrocarbon solvents as the cleaning medium, enhancing the cleaning effect through a vacuum environment. They are widely used in electronics manufacturing, precision machining, and automotive parts production. In electronic chip manufacturing, it is necessary to remove photoresist and metallic impurities from wafer surfaces; after precision machining, residual cutting fluid, oil, and other contaminants on parts surfaces also need to be removed; similarly, in the production of automotive engine parts, deep cleaning of grease and debris from complex internal structures is required. Hydrocarbon vacuum cleaners, thanks to the excellent solubility of hydrocarbon solvents in oil, grease, and other organic matter, and the better penetration ability of the cleaning fluid under vacuum, achieve highly efficient cleaning of workpieces, ensuring product quality and performance.

[0003] Currently, existing hydrocarbon vacuum cleaners lack effective coordination in the cleaning process. Single cleaning methods are insufficient to penetrate the fine structure of the workpiece, resulting in poor cleaning of deep grease and stubborn contaminants, leading to incomplete cleaning and affecting the subsequent processing and performance of the workpiece. Therefore, an integrated hydrocarbon vacuum cleaner with a steam composite tank is proposed. Summary of the Invention

Detailed Implementation

[0031] 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.

[0032] Referring to Figures 1-3, one embodiment of this utility model provides a steam composite tank for an integrated hydrocarbon vacuum cleaner, including a base plate 1. The base plate 1 serves as the basic load-bearing component of the entire steam composite tank, providing a stable mounting surface for other components. A tank body 2 is fixedly connected to the top left side of the base plate 1. The tank body 2 is the core working area for accommodating the items to be cleaned and the cleaning fluid. A storage tank 3 is fixedly connected to the top right side of the base plate 1. The storage tank 3 is used to store the hydrocarbon cleaning fluid required during the cleaning process and to collect the cleaning fluid returning from the tank body 2. A circulation pump 4 is installed between tank 2 and storage tank 3. The circulation pump 4 can draw the cleaning solution from storage tank 3 and transport it to tank 2, realizing the circulation of the cleaning solution between tank 2 and storage tank 3, ensuring the continuous cleaning process. A water spray pipe 6 is fixedly connected to the middle of the inner wall of tank 2. The water spray pipe 6 is used to guide the cleaning solution to various high-pressure nozzles 7. Multiple high-pressure nozzles 7 are fixedly connected to the outer wall of water spray pipe 6. The high-pressure nozzles 7 can spray the cleaning solution into the workpiece in the form of high-pressure jet, enhancing the cleaning effect and improving the cleaning efficiency. Multiple heaters 8 are fixedly connected to the bottom of the inner wall of tank 2. The heaters 8 vaporize the cleaning solution at low temperature. The solvent vapor penetrates into the fine structure of the workpiece and then condenses to dissolve deep grease. A return pipe 10 is fixedly connected to the bottom of the heaters 8. The return pipe 10 is used to guide the used cleaning solution in tank 2 back to storage tank 3, realizing the recycling of the cleaning solution. A filter assembly is installed on the outer wall of the return pipe 10.

[0033] Referring to Figure 4, the filter assembly includes a filter box 12, which is fixedly connected to the outer wall of the return pipe 10. The filter box 12 provides installation space for the filter screen 14. The filter screen 14 is installed inside the filter box 12. The filter screen 14 can intercept impurities mixed in the cleaning fluid, ensuring the cleanliness of the cleaning fluid returned to the storage tank 3. A fixing component is installed on the inner wall of the filter box 12 to fix the filter screen 14, ensuring that the filter screen 14 is stable and reliable during the filtration process. At the same time, it ensures that the filter screen 14 can be quickly disassembled and cleaned after long-term use.

[0034] Referring to Figure 5, the fixing assembly includes four guide rods 17. The guide rods 17 are fixedly connected to the inner wall of the filter box 12. The guide rods 17 provide guidance for the sliding of the limiting block 16, ensuring the stability and accuracy of the movement of the limiting block 16. The limiting block 16 is slidably connected between the outer walls of two adjacent guide rods 17. The limiting block 16 slides on the guide rod 17, which can limit the pull rod 15. The pull rod 15 is fixedly connected to the middle of the limiting block 16. The pull rod 15 is easy for the operator to pull, realizing the installation and disassembly of the filter screen 14. The outer wall of the guide rod 17 is fitted with a spring 18. The spring 18 provides elastic force, so that the limiting block 16 can automatically reset when no external force is applied, driving the pull rod 15 to reset, ensuring the stable fixing of the filter screen 14.

[0035] Referring to Figure 1, a delivery pipe 5 is provided between the output end of the circulation pump 4 and the storage tank 3. The delivery pipe 5 is used to transport the cleaning fluid drawn by the circulation pump 4 back to the storage tank 3 to realize the return of the cleaning fluid. A delivery pipe 5 is also provided between the output end of the circulation pump 4 and the spray pipe 6. The delivery pipe 5 is used to transport the cleaning fluid drawn by the circulation pump 4 to the spray pipe 6 to provide a source of cleaning fluid for the high-pressure nozzle 7.

[0036] Referring to Figures 1 and 3, a control valve 11 is provided on the outer wall of the connection between the return pipe 10 and the bottom of the tank 2. The control valve 11 is used to control the flow of cleaning fluid in the tank 2 to the return pipe 10. The return channel can be opened or closed according to the actual cleaning needs. A one-way valve 13 is provided on the outer wall of the end of the return pipe 10 away from the tank 2. The one-way valve 13 ensures that the cleaning fluid can only flow from the tank 2 to the storage tank 3 through the return pipe 10, preventing the cleaning fluid from flowing back.

[0037] Referring to Figure 1, a vacuum pump 21 is fixedly connected to the top edge of the base plate 1. A pipe is provided between the output end of the vacuum pump 21 and the inside of the tank 2. The vacuum pump 21 is used to extract the air inside the tank 2 to create a vacuum environment inside the tank 2, which is conducive to the cleaning liquid better penetrating into the gaps of the items to be cleaned and improving the cleaning effect.

[0038] Referring to Figures 1 and 2, a hot nitrogen injection pipe 9 is fixedly connected to the top edge of the tank 2. The hot nitrogen injection pipe 9 is used to inject hot nitrogen into the tank 2. On the one hand, it can accelerate the drying of the surface of the item to be cleaned. On the other hand, the hot nitrogen can replace the air in the tank 2, reduce the oxygen content, and improve the safety of the cleaning process.

[0039] Referring to Figures 1-3, a control panel 19 is fixedly connected to the outer wall of the tank 2. The control panel 19 is electrically connected to the circulating pump 4, the vacuum pump 21, and the heater 8. The control panel 19 serves as the control center of the entire steam composite tank, allowing operators to set various parameters and control the equipment. Operators can control the start and stop of the circulating pump 4 and adjust its flow rate through the control panel 19 to control the circulation of the cleaning fluid. They can also control the working status of the vacuum pump 21, adjust the vacuum level in the tank 2, and set the heating temperature and time of the heater 8 to control the temperature of the cleaning fluid.

[0040] Referring to Figure 5, the pull rod 15 passes through the filter box 12 and engages with the filter screen 14. By engaging the pull rod 15 with the filter screen 14, the filter screen 14 can be quickly installed and removed, making it convenient for operators to clean and replace the filter screen 14.

[0041] Working Principle: When cleaning is required, the hydrocarbon cleaning solution in the storage tank 3 is transported to the tank 2 by the circulating pump 4. The solution is then sprayed through the high-pressure nozzle 7 to pre-clean the workpiece, initially removing large particulate contaminants from the surface. After use, the cleaning solution enters the filter box 12 through the bottom return pipe 10, where it passes through the filter screen 14 to intercept impurities before returning to the storage tank 3 for reuse. Subsequently, the system enters the steam cleaning stage. The vacuum pump 21 draws air from the tank to create a low-pressure environment, which, combined with the heater 8, causes the cleaning solution to vaporize at low temperature. The solvent vapor penetrates the fine structure of the workpiece, condenses, and dissolves deep-seated grease. Contaminants are then filtered and recovered with the condensate through the return system. After cleaning, the vacuum pump 21 further reduces the pressure inside the tank to accelerate the evaporation of residual solvent. Simultaneously, hot nitrogen is injected to replace oxygen and assist in drying, preventing workpiece oxidation and improving safety.

[0042] When the filter screen 14 needs to be cleaned or replaced after long-term use, the operator pulls the lever 15, which causes the limit block 16 to slide on the guide rod 17, releasing the limit on the filter screen 14. The filter screen 14 can then be easily removed for maintenance. After maintenance, the filter screen 14 is reinstalled to prepare for the next cleaning.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
