Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, specifically to an oil-filled assembly for multi-station cleaning equipment. Background Technology

[0002] In multi-station cleaning equipment, the oil-filled assembly, a key functional component welded to the outer wall of the cleaning tank, primarily serves to contain and circulate the heat-conducting oil, providing insulation, energy storage, and uniform heat transfer. Traditional oil-filled assemblies often employ a diagonal welding method between plates. While this method is structurally simple, it has significant drawbacks in actual operation. Because the heat-conducting oil inside the oil-filled assemblies needs to continuously flow back and forth for heat exchange, the oil undergoes frequent thermal expansion and contraction during heating and cooling. The diagonal welding method causes stress concentration at the weld points, making it difficult to effectively release thermal stress. Over time, this can easily lead to fatigue cracking at the welded areas and overall structural deformation, affecting sealing performance and causing oil leakage. This not only reduces the equipment's lifespan but also poses safety hazards. Therefore, there is an urgent need for an oil-filled assembly with a reasonable structure, strong welds, and uniform heat distribution to improve the overall performance and reliability of the cleaning equipment. Utility Model Content

[0003] The purpose of this invention is to provide an oil-filled assembly for a multi-station cleaning equipment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil-filled assembly for a multi-station cleaning equipment, comprising an oil-filled front plate, an oil-filled rear plate, a first oil-filled side plate, a second oil-filled side plate, and an oil-filled lower plate; one side of the oil-filled front plate is connected to the first oil-filled side plate via a first folded edge, and the other side of the oil-filled front plate is connected to the second oil-filled side plate via a second folded edge; the oil-filled rear plate is connected to the second oil-filled side plate via a third folded edge; the oil-filled front plate, oil-filled rear plate, first oil-filled side plate, second oil-filled side plate, and oil-filled lower plate together form a U-shaped structure with a top opening; multiple oil-filled ribs are provided on the inner sides of the oil-filled front plate, oil-filled rear plate, first oil-filled side plate, second oil-filled side plate, and oil-filled lower plate, and each oil-filled rib is welded to the inner wall of its respective plate, forming an oil flow channel between adjacent oil-filled ribs; a communication port for oil flow is provided between the oil-filled rear plate and the oil-filled lower plate.

[0005] Preferably, the front plate of the oil tank is provided with an observation clearance hole and an exhaust hole for avoiding the viewing window.

[0006] Preferably, the front oil pack plate, rear oil pack plate, first oil pack side plate, second oil pack side plate, and lower oil pack plate are each provided with multiple connection holes for welding to the outer wall of the cleaning tank.

[0007] Preferably, the oil-coated reinforcing plates are made of flat steel and are arranged in parallel at intervals on the inner side of each plate.

[0008] Preferably, the lower plate of the oil tank is provided with a drainage clearance hole in the middle for avoiding the drainage pipe.

[0009] Preferably, an oil drain hole is also provided on the side of the drain clearance hole.

[0010] Compared with existing technologies, this utility model provides an oil-filled assembly for multi-station cleaning equipment, which has the following beneficial effects: This utility model significantly improves the overall performance of the oil-filled assembly through overall structural optimization and improved welding processes. By using edge welding instead of the traditional diagonal welding method, the weld seam is transferred from the stress-concentrated corners to the sides of the plates, effectively dispersing thermal stress and reducing the risk of welding deformation and fatigue cracking caused by the thermal expansion and contraction of the heat transfer oil, thus enhancing the overall structural robustness and durability. The oil-filled ribs set on the inner sides of each plate not only enhance the structural strength but also form uniformly distributed oil flow channels, making the heat transfer oil flow smoother and the temperature distribution more uniform, avoiding local overheating or flow dead zones, thereby improving heat exchange efficiency and temperature uniformity. In addition, the U-shaped structure of the oil-filled assembly, along with functional holes such as observation clearance holes, vent holes, connection holes, drain clearance holes, and oil drain holes, achieves a high degree of integration with the cleaning tank and convenient maintenance. The overall structure is compact and the functions are complete, which significantly extends the service life and reduces the risk of leakage. It is suitable for industrial cleaning environments with continuous operation in multiple workstations and has high practical value and promotion prospects. Attached Figure Description

[0013] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model: like Figure 1-6 As shown, this utility model provides an oil tank assembly for a multi-station cleaning equipment, including an oil tank front plate 1, an oil tank rear plate 2, a first oil tank side plate 31, a second oil tank side plate 32, and an oil tank lower plate 4. One side of the oil tank front plate 1 is welded to the first oil tank side plate 31 via a first folded edge 11, and the other side of the oil tank front plate 1 is welded to the second oil tank side plate 32 via a second folded edge 12. The oil tank front plate 1, the first folded edge 11, and the second folded edge 12 are integrally formed, with a folded edge width of 50-100mm, which can be adjusted according to the overall size of the oil tank and welding process requirements. This folded edge welding structure replaces the traditional corner butt welding method, transferring the weld from the stress-concentrated corner to the side of the plate, effectively dispersing the cyclic thermal stress caused by the thermal expansion and contraction of the thermally conductive oil, significantly improving the fatigue strength of the welded joint, and reducing the risk of cracking caused by thermal cycling. The rear plate 2 of the oil tank is welded to the second side plate 32 of the oil tank via the third fold 21, and the rear plate 2 and the third fold 21 are integrally formed. The rear plate 2 is not connected to the first side plate 31 of the oil tank. This design reduces unnecessary welding points and further reduces structural complexity and stress concentration risk. The front plate 1, rear plate 2, first side plate 31, second side plate 32, and lower plate 4 of the oil tank together form a U-shaped structure with an open top. This structure is welded to the outer wall of the cleaning tank 10 to form a sealed oil cavity, which is used to contain and guide the circulating flow of heat transfer oil, thereby achieving heat preservation and heat energy retention of the cleaning tank 10.

[0014] Multiple reinforcing plates 5, made of flat steel, are provided on the inner sides of the front plate 1, rear plate 2, first side plate 31, second side plate 32, and lower plate 4 of the oil tank. These plates are arranged in parallel at intervals on the inner sides of each plate. Each reinforcing plate 5 is welded to the inner wall of the plate it belongs to, enhancing the overall structural strength. Oil flow channels 6 are formed between adjacent reinforcing plates 5, effectively guiding the heat transfer oil to flow evenly, avoiding localized temperature differences, and improving heat transfer efficiency. A connecting port 7 is provided between the rear plate 2 and the lower plate 4 to ensure unobstructed flow of oil within the oil tank assembly.

[0015] The front plate 1 of the oil tank is provided with an observation clearance hole 8 and an exhaust hole 9. The observation clearance hole 8 is used to avoid the observation window on the cleaning equipment, so that the operator can observe the working status inside the cleaning tank 10 and the cleaning status of the workpieces in the washing basket 16 in real time. The exhaust hole 9 is used to remove gas in the oil chamber during oil filling or operation, to prevent air blockage and ensure smooth oil circulation. The front plate 1, the rear plate 2, the first side plate 31, the second side plate 32, and the lower plate 4 of the oil tank are all provided with multiple connection holes 13. Through these holes, the oil tank assembly can be welded and fixed to the outer wall of the cleaning tank 10 as a whole, which not only achieves a stable connection and enhances the overall structural rigidity, but also facilitates efficient heat conduction.

[0016] A drain clearance hole 14 is provided in the middle of the lower plate 4 of the oil tank to avoid the drain pipe at the bottom of the cleaning tank 10, ensuring that the waste liquid generated during the cleaning process can be discharged smoothly without affecting the normal operation of the oil tank assembly. An oil drain hole 15 is also provided on the side of the drain clearance hole 14, which is used to quickly drain the oil in the oil chamber when the equipment is maintained, repaired or replaced with heat transfer oil, improving the maintainability and ease of operation of the equipment.

[0017] The working principle and process of this utility model are as follows: During equipment assembly, the oil-filled assembly is first welded and fixed to the outer wall of the cleaning tank 10 through the connecting hole 13, thus forming a sealed oil cavity. This oil cavity is filled with heat-conducting oil. When the equipment is started, the heat-conducting oil is heated by an external heat source. The heated oil circulates within the cavity, and its flow path is guided and constrained by the oil flow channel 6 formed by the oil-filled ribs 5, thereby achieving a uniform and efficient heat distribution. Heat is continuously transferred to the cleaning tank 10 through the metal plate wall, providing a stable and uniform heat supplement, effectively offsetting the heat loss caused by steam condensation and vacuum drying during the cleaning process, and maintaining a highly stable process temperature within the tank. The washing basket 16 carries the workpiece placed inside the cleaning tank 10, undergoing steam pre-washing, vacuum drying, and other processes under a stable temperature environment, ultimately achieving a high-quality cleaning effect. This utility model effectively reduces the risk of thermal stress concentration and structural deformation by optimizing the structural layout and welding process, extending the service life of the equipment, and is suitable for multi-station, continuous industrial cleaning scenarios.

[0018] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
