Description

Technical Field

[0001] This utility model relates to the field of oil tank cleaning technology, and in particular to portable oil tank cleaning equipment. Background Technology

[0002] During use, oil tanks accumulate condensate due to temperature changes. This condensate accelerates the emulsification of the fuel stored in the tank, corrodes the tank walls, and gradually increases the amount of sludge adhering to the tank walls. At the same time, the tanks also contain a large amount of dried mud, paraffin wax, bacteria, and other impurities. These impurities accumulate on the bottom and inner walls of the tank over time, causing blockages, corrosion, and leaks if not cleaned regularly. However, many oil tanks are cleaned manually, with workers wearing protective equipment entering the tanks for cleaning. However, the presence of large amounts of toxic and harmful gases in the tanks limits the time workers can spend inside, reducing work efficiency. Furthermore, personnel entering the tanks need to carry lights and communication equipment, and the presence of large amounts of flammable and explosive gases increases the risk to workers. Therefore, portable oil tank cleaning equipment has emerged to address the shortcomings of traditional oil tank cleaning methods.

[0003] These types of equipment are characterized by their small size, light weight, portability, and ease of operation, making them suitable for cleaning oil tanks of different types and sizes. They are particularly suitable for cleaning oil tanks in small gas stations, factory storage tanks, and oil tanks in remote areas that are difficult to access. However, due to limitations in equipment size and power, they lack automated monitoring, and their cleaning efficiency and effectiveness may not be as good as large professional cleaning equipment. For large oil tanks and those with particularly severe or stubborn oil stains, extremely long cleaning times are required, leading to a significant increase in water consumption. Furthermore, the single cleaning angle makes it difficult to achieve very high cleaning standards. Currently, automated cleaning technologies are being used in the market, allowing for single-person operation, reducing manpower input, and improving cleaning efficiency. For example, systematic automated cleaning technologies are being developed using electronic control technology, which uses sensors and controllers to automate the cleaning process. However, these technologies cannot precisely clean oil tanks with irregular shapes and complex internal structures, often resulting in excessive water consumption. During continuous cleaning operations, frequent water replenishment may be required, which not only affects cleaning efficiency and effectiveness but also increases water costs.

The filtered water then comes to the bottom of the second water storage tank. Finally, the centrifugal pump transports the water through a transmission pipe to the first water storage tank to complete the circulation. Attached Figure Description

[0032] 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.

[0033] Please see the appendix Figure 2 - Appendix Figure 4This utility model provides an embodiment of a portable oil tank cleaning device, including a base 1. A water storage tank 3 is fixedly connected to the top right side of the base 1. A water outlet pipe 4 is connected to the right side of the outer wall of the water storage tank 3, serving as a channel for water to flow out of the water storage tank 3. A rotary joint 5 is fixedly connected to the bottom end of the water outlet pipe 4, allowing connected components to rotate freely. A rotating disc 6 is rotatably connected inside the rotary joint 5. An impeller 7 is fixedly connected to the top of the outer wall of the rotating disc 6, generating power through high-pressure water flow. A conveying pipe 8 is connected to the middle of the outer wall of the rotating disc 6, serving as a channel for water to flow from the rotating disc 6 to subsequent components. A bevel gear 9 is fixedly connected to the middle of the outer wall of the conveying pipe 8. A bevel gear 10 is fixedly connected to the bottom of the outer wall. It is driven to rotate by the rotation of the impeller 7. The outer walls of both bevel gear 10 and bevel gear 9 are meshed with curved gears 11, which mesh with the upper and lower gears. Due to their rotation, the curved gears 11 rotate. The bottom right side of the conveying pipe 8 is connected to the water inlet pipe 12, which transports water to the rotating nozzle 13. The right side of the outer wall of the curved gear 11 is fixedly connected to the rotating nozzle 13. The front and rear sides of the outer wall of the rotating nozzle 13 are fixedly connected to rotating nozzles 14, which can achieve multi-angle spraying under the drive of the rotating nozzle 13. The top left side of the base 1 is fixedly connected to the circulation structure 2, which is used to recycle water resources and save costs.

[0034] Specifically, firstly, cleaning water is injected into the equipment through the outlet pipe 4. The water flow is delivered to the rotating disc 6. The high-pressure water flow impacts the impeller 7, causing the impeller 7 to start rotating. This, in turn, drives the rotating disc 6 and the conveying pipe 8 to rotate together. The bevel gear 1 9 and bevel gear 2 10 on the conveying pipe 8 rotate accordingly. Through the meshing transmission with the curved gear 11, the power is transmitted to the rotating nozzle 13, causing the rotating nozzle 13 to rotate at high speed. At the same time, the water flow passes through the inlet pipe 12 during the delivery process and is sprayed out from the rotating nozzle 14.

[0035] Please see the appendix Figure 5 - Appendix Figure 7The circulation structure 2 includes a second water storage tank 201. The bottom of the second water storage tank 201 is fixedly connected to the base 1. A liquid pump 206 is fixedly connected to the inside of the second water storage tank 201 near the edge, which can efficiently extract sewage from the oil tank. A connecting pipe 203 is fixedly connected to the output end of the liquid pump 206. A filter screen 207 is fixedly connected to the other end of the liquid pump 206 to intercept larger particulate impurities in the sewage. A suction nozzle 204 is fixedly connected to the top of the connecting pipe 203 to fit against the bottom of the oil tank and effectively suck up sewage. A connection port 205 is opened inside the suction nozzle 204 to connect to the connecting pipe. 203 are closely connected. Fixing blocks 211 are fixedly connected to the left and right sides of the middle part of the water storage tank 201 to connect and fix the filter plate 208 and the oil suction filter element 209. The filter plate 208 is fixedly connected to the outer wall of the fixing block 211. The oil suction filter element 209 is fixedly connected to the outer wall of the fixing block 211, which can quickly absorb the oil in the sewage. The centrifugal water pump 210 is fixedly connected to the bottom of the water storage tank 201 to draw the treated water from the bottom of the water storage tank 201. The output end of the centrifugal water pump 210 is fixedly connected to the transmission pipe 202 to transport the purified water to the water storage tank 3.

[0036] Specifically, firstly, the liquid pump 206 is started, and the sewage in the oil tank is drawn into the water storage tank 201 through the suction nozzle 204 and the connecting pipe 203. During the process of sewage entering, the filter screen 207 performs preliminary filtration of sewage. Then the sewage flows through the filter plate 208 and the oil suction filter element 209 in sequence to remove suspended particles and oil, respectively, to achieve deep purification of sewage. The purified water is collected at the bottom of the water storage tank 201 and is transported back to the water storage tank 3 by the centrifugal pump 210 through the transmission pipe 202.

[0037] Please see the appendix Figure 1 - Appendix Figure 2 The bottom of the rotary joint 5 is fixedly connected to a protective shell 15. The inside of the rotary joint 5 is provided with an annular groove 16 to provide space for the rotation of the impeller 7. The bottom of the base 1 is fixedly connected to a support column 17. The bottom ends of multiple support columns 17 are rotatably connected to wheels 18 to provide convenience. The outer wall of the right side of the base 1 is provided with a slot 19 for placing the nozzle structure. The top of the water storage tank 3 is rotatably connected to an organic cover 22.

[0038] Specifically, when the cleaning equipment needs to be moved, it can be moved by the wheels consisting of the support column 17 and the wheel 18. The annular groove 16 in the cleaning equipment provides space for the rotating structure, and the slot 19 on the outer wall of the base 1 is used to place the nozzle.

[0039] Please see the appendix Figure 3 - Appendix Figure 5A high-pressure water pump 25 is fixedly connected to the front of the interior of water tank 3 to transport water from water tank 3 to water outlet pipe 4. A water injection pipe 24 is connected to the rear outer wall of water tank 3 so that water can be replenished when water in water tank 3 is low. A rotating shaft 20 is rotatably connected to the outer wall of the slot 19 near the edge. A limit block 21 is fixedly connected to the outer wall of the two rotating shafts 20 for fixing the nozzle. The top of water tank 201 is rotatably connected to cover 23. A water inlet 26 is opened on the rear of the interior of water tank 3 and connected to water injection pipe 24.

[0040] Specifically, when the nozzle is installed in the slot 19, it is fixed by the rotating shaft 20 and the limiting block 21. When the high-pressure water pump 25 is started, the water in the water storage tank 3 is transported to the water outlet pipe 4. When there is a water shortage, water can also be added directly by the water injection pipe 24.

[0041] Working principle: When cleaning is required, high-pressure water flows through the outlet pipe 4 to the rotary joint 5. Due to the water pressure, the rotating mechanism consisting of the rotating disc 6 and the impeller 7 rotates, thereby rotating the conveying pipe 8. The rotation of the conveying pipe 8 sends power to the bevel gear 9 and bevel gear 10, causing them to rotate. The power is then transmitted to the bevel gear 11 that meshes with the bevel gear 9 and bevel gear 10, thereby driving the rotating nozzle 13 to rotate as well. At the same time, high-pressure water is delivered to the rotating nozzle 13 through the inlet pipe 12. The high-pressure water in the rotating nozzle 13 is sprayed through the rotating nozzle 14. During the rotation, the inner wall of the oil tank is cleaned in all directions. This rotating jet method can effectively improve cleaning efficiency and quality, ensuring that the dirt on the inner wall of the oil tank is thoroughly removed.

[0042] During the cleaning process, the liquid pump 206 in the second water storage tank 201 can be started. The wastewater generated is sucked into the second water storage tank 201 through the suction nozzle 204 connected by the connecting pipe 203. When the wastewater enters the second water storage tank 201, it first passes through the filter screen 207 on the liquid pump 206 to filter impurities. Then it flows into the second water storage tank 201 and passes through the filter plate 208 and the oil suction filter element 209 to filter impurities and oil droplets in the oil and water, thereby achieving oil-water separation. Due to its density, the water reaches the bottom of the second water storage tank 201. Then, the water is pumped out by the centrifugal pump 210 and discharged into the interior of the first water storage tank 3 through the transmission pipe 202, achieving recycling, reducing water waste and environmental pollution, and also reducing cleaning costs.

[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.
