DETAILED DESCRIPTION

[0044] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0045] Example 1

[0046] One embodiment of the present invention, as Figure 1 As shown, a cleaning system for an oil tank with a complex internal structure is provided, comprising a cleaning platform 2, a cleaning device 3 and a filtering device 5.

[0047] The oil tank 1 is fixedly placed on the cleaning platform 2, and the cleaning device 3 fills the oil tank 1 with oil for cleaning. The cleaned oil is detected by the pollution detection device 6. If it meets the cleanliness requirements, it is re-injected into the oil storage tank of the cleaning device 3; if it does not meet the cleanliness requirements, it is filtered by the filtering device 5 and injected into the oil storage tank of the cleaning device 3 after the cleanliness meets the requirements. The cleaning oil is injected into the oil storage tank of the cleaning device 3 and then recycled.

[0048] The cleaning platform 2 comprises a fuel tank rack 22 and a tool 21. The fuel tank rack 22 is a rectangular parallelepiped frame formed by welding aluminum alloy profiles, and is used to support the tool 21 and the fuel tank 1.

[0049] The tooling 21 is used to fix the oil tank 1 , and the bottom of the tooling 21 is fixed to the oil tank placement rack 22 .

[0050] There are multiple toolings 21 . Specifically, the number of toolings 21 matches the length of the fuel tank 1 .

[0051] Furthermore, the cleaning platform 2 also includes a shaking device 23, which is used to shake the oil tank 1 so that the cleaning oil in the oil tank 1 fully contacts various parts inside the oil tank 1, and removes and removes excess materials from the inner wall. In this embodiment, the shaking device 23 is a first shaking device 231. Two first shaking devices 231 are provided, and the two first shaking devices 231 are provided at the lower part of the oil tank placement rack 22.

[0052] like Figure 2 As shown, the first shaking device 231 includes a first motor and an eccentric shaft.

[0053] The first motor is symmetrically arranged on both sides of the lower part of the oil tank rack 22, and the ends of the eccentric shaft are respectively connected to the outermost frames of the oil tank rack 22. The first motor drives the eccentric shaft to rotate and shake, and the eccentric shaft drives the rotating shaft and the oil tank rack 22 to shake left and right, thereby causing the oil tank 1 to shake left and right, so that the cleaning oil inside the oil tank 1 collides with and washes the inner wall of the oil tank 1, so that the excess materials are peeled off, thereby improving the cleaning effect.

[0054] Compared with the prior art, the present embodiment is provided with a motor and an eccentric shaft, and the ends of the eccentric shaft are arranged on the two outermost upper frames of the oil tank placement rack 22. When the motor rotates, the eccentric shaft rotates, driving the oil tank placement rack 22 and the oil tank 1 to swing left and right, so that the cleaning oil in the oil tank 1 shakes to collide with the inner wall of the oil tank, and the excess matter stuck to the wall is washed down by the cleaning oil, and the excess matter is taken out when returning the oil, so that the cleaning of the inside of the oil tank 1 is more thorough.

[0055] The cleaning equipment 3 has an oil storage tank, which is used for filling oil and cleaning the cabin. Before filling oil, the oil inlet pipe and the oil outlet pipe in the cleaning equipment 3 need to be connected for self-circulation, and the oil can be used for filling oil in the cabin after reaching the required cleanliness. During cleaning, an oil filling port and an oil return port are set on the oil tank 1, and multiple oil filling and oil return are performed to achieve the purpose of cleaning the oil tank 1. Specifically, the oil outlet pipe of the oil storage tank of the cleaning equipment 3 is connected to the oil filling port of the oil tank 1, and the oil return port of the oil tank 1 is connected to the filtering device 5. The discharged oil is tested before filtering. If the required cleanliness is not reached after the test, the oil is filtered, and the oil is re-injected into the oil storage tank after the filtration reaches the required cleanliness; after the test, the oil is re-injected into the oil storage tank after reaching the required cleanliness.

[0056] Furthermore, an air filling device 4 is provided. The air filling device 4 is used to fill gas into the oil tank 1 during the cleaning process of the oil tank 1 to mix with the cleaning oil. The gas can speed up the flow of the cleaning oil, form a vortex, increase the flushing force on the cleaning part, and improve the cleaning quality.

[0057] The filter device 5 is used to filter the oil and excess materials discharged after the cabin is cleaned to the required cleanliness. Figure 3 As shown, in this embodiment, the filter device 5 is a single filter assembly 51. For example, the filtering accuracy is 10um. The oil filtered by the filter device 5 is re-input into the oil storage tank of the cleaning device 3, and there is a finer filter in the oil storage tank. The oil filtered by the fine filter is transported to the cabin as clean oil and continues to be used for cleaning the cabin.

[0058] Furthermore, it also includes a pollution detection device 6 for detecting the cleanliness and cleaning effect of the kerosene cleaning medium.

[0059] Example 2

[0060] The difference between this embodiment and embodiment 1 is that the first shaking device 231 in embodiment 1 can only swing left and right. In order to improve the swinging effect, this embodiment adopts a second shaking device 232 with a crank 2321 and a rocker 2323 structure to replace the first shaking device 231; at the same time, in order to make the cleaning oil filtering more thorough, this embodiment arranges a superimposed filter assembly 52 to replace the single filter assembly 51 of embodiment 1.

[0061] like Figure 4As shown, the second shaking device 232 includes a crank bracket 2324, a crank 2321, a connecting rod 2322, a rocker 2323 and a second motor. The crank 2321 is mounted on the crank bracket 2324, and the crank 2321 can rotate in a full circle around its own rotation axis when driven by the second motor.

[0062] The two end surfaces of the oil tank 1 are provided with end covers, and the center of the end covers is fixed to the end of the rocker 2323. The connecting rod 2322 is provided between the crank 2321 and the rocker 2323. When the crank 2321 rotates, the rocker 2323 and the oil tank 1 are driven to swing up, down, left and right through the connecting rod 2322. It should be noted that the length of the rocker 2323 and the connecting rod 2322 is designed according to the angle at which the rocker 2323 needs to swing.

[0063] Compared with the first shaking device 231 in Example 1 that makes the oil tank 1 swing left and right, the arrangement of the crank 2321, the rocker 2323 and the connecting rod 2322 in this embodiment enables the rocker 2323 to drive the oil tank 1 to swing up, down, left and right, so that the cleaning oil can swing in more dimensions in the oil tank 1 and enter more hard-to-reach cleaning dead corners, thereby further improving the cleaning effect.

[0064] like Figure 5 As shown, the superimposed filter assembly 52 includes a plurality of filter screens. Exemplarily, three filter screens are provided in this embodiment. The superimposed filter assembly 52 in this embodiment includes a first filter screen 521, a second filter screen 522, a third filter screen 523, an oil collecting component 524 and a surplus collecting bucket 525.

[0065] The first filter screen 521, the second filter screen 522 and the third filter screen 523 are arranged from top to bottom, and the filtering accuracy increases in sequence. The first filter screen 521 is a coarse filter, and illustratively, the filtering accuracy is 15mm; the second filter screen 522 is a medium filter, and illustratively, the filtering accuracy is 1mm; the third filter screen 523 is a fine filter, and illustratively, the filtering accuracy is 5um. In order to facilitate the collection of excess matter, the shapes of the first filter screen 521, the second filter screen 522 and the third filter screen 523 are all hollow mesh structures with an arc-shaped concave surface in the middle, which is convenient for collecting excess matter in the middle of the filter screen. Furthermore, each filter screen is tilted so that the excess matter can slide to the lower end of the filter screen by gravity.

[0066] A surplus collecting bucket 525 is provided at the lower end of each filter screen for collecting surplus matter filtered out of the filter screen.

[0067] The waste collecting bucket 525 is arranged on the collecting bucket placing frame 5251. The collecting bucket placing frame 5251 has a plurality of slots, and the two ends of the waste collecting bucket 525 can be inserted into the slots for fixing. The waste collecting bucket 525 can be removed after the waste is full.

[0068] like Figure 6 As shown, the oil collecting component 524 is arranged at the lower part of the third filter screen 523, and is used to collect the oil after three layers of filtration. An oil collecting hopper 5241 is arranged at the end of the oil collecting component 524, and is used to store and place the oil in the oil collecting component 524. Furthermore, the oil collecting component 524 is arranged obliquely, and a cushion block 5243 is arranged at the lower part of the end away from the oil collecting hopper 5241, so as to facilitate the oil in the oil collecting component 524 to flow into the oil collecting hopper 5241 by gravity. An oil filter outlet pipe 5242 is arranged on the side of the oil collecting hopper 5241, and is used to transport the oil on the side of the oil collecting hopper 5241 to the oil storage tank of the cleaning device 3, and is used for recycling the cleaning oil.

[0069] This embodiment is provided with a superimposed filter assembly 52, and filters of different precisions are arranged from top to bottom to intercept different levels of excess matter. The first filter 521 is a coarse filter, used to intercept large particles of impurities; the second filter 522 is a medium filter, used to intercept medium particles of impurities; the third filter 523 is a fine filter, used to intercept fine impurities. The oil discharged from the oil tank 1 is filtered by the multi-layer superimposed filter assembly 52, which can effectively prevent impurities of different sizes from passing through, avoid impurities accumulating and clogging the filter, improve the filtering accuracy, and ensure that the quality of the cleaning oil meets the requirements for recycling.

[0070] Furthermore, the stacked filter assembly 52 further includes a dumping device 526. The dumping device 526 is symmetrically arranged on both sides of the first filter 521, the second filter 522 and the third filter 523. The dumping device 526 includes a rotating bracket 5261, a first rotating shaft 5262, a pressing plate 5263 and a rocker arm 5264.

[0071] Both ends of the first filter 521, the second filter 522 and the third filter 523 are arranged on the rotating bracket 5261, and the rotating bracket 5261 is provided with a first rotating shaft 5262 at the position corresponding to the filter. The first filter 521, the second filter 522 and the third filter 523 can rotate around the first rotating shaft 5262 and tilt at multiple angles.

[0072] For ease of operation, a pressing plate 5263 is also provided on both sides of each filter. The pressing plate 5263 is an L-shaped plate, including a first side and a second side. The plane of the first side is fitted and fixed with the planes on both sides of the filter, and the second side is fitted with the rotating bracket 5261 and is hinged with the rotating bracket 5261 through a second rotating shaft. When the pressing plate 5263 is rotated, the filter rotates accordingly.

[0073] Furthermore, a rocker arm 5264 is provided on the other side of the rotating bracket 5261, and the rocker arm 5264 is coaxially arranged with the pressing plate 5263 and can rotate simultaneously.

[0074] When the excess material needs to be dumped, the rocker arm 5264 is rotated to make the first side of the pressing plate 5263 press down the filter screen, so that the filter screen is tilted, and the excess material in the filter screen enters the excess material collecting bucket 525.

[0075] Compared with the prior art, the present embodiment provides a rocker arm 5264 and a pressing plate 5263 to press the filter screen, thereby rotating the filter screen to dump the collected excess materials, which is easy to operate.

[0076] Furthermore, since the filtering accuracy of the third filter screen 523 is relatively high and the pores are very small, some small excess materials such as iron filings brought out by the cleaning oil will adhere to the third filter screen 523. Excessive accumulation of excess materials will affect the filtering effect. The superimposed filter screen assembly 52 of this embodiment is also provided with a scraper structure 527 for scraping small excess materials adhered to the third filter screen 523 into the excess material collection bucket 525.

[0077] The scraper structure 527 includes a scraper frame 5271, a scraper handle 5272 and a scraper 5273. The scraper frame 5271 is arranged on the end surface of the third filter screen 523 away from the excess collection bucket 525, and has a through hole in the middle for inserting the scraper handle 5272. The scraper 5273 is arranged at the end of the scraper handle 5272. The curvature of the bottom of the scraper 5273 is the same as the curvature of the middle of the third filter screen 523.

[0078] Compared with the prior art, the present embodiment is provided with a scraper structure 527, the curvature of the bottom of the scraper 5273 is the same as the curvature of the middle of the filter, and is used to scrape small excess matter adhered to the third filter 523 into the excess matter collection bucket 525 to prevent excess matter from accumulating and blocking the filter mesh.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
