Description

Technical Field

[0001] The utility model relates to the technical field of temporary storage and transportation of waste lubricating oil, in particular to a storage container which can hold waste lubricating oil and is convenient for transfer and transportation with vehicles, in particular to a waste lubricating oil transfer container. Background Art

[0002] Lubricating oil will gradually age and deteriorate during use. Recycling and reuse can effectively conserve crude oil resources and reduce the demand for new resources.

[0003] Traditionally, waste lubricating oil has been treated in a variety of ways, including physical, chemical, and biological methods. Before lubricating oil can be treated, it is usually necessary to collect and transport waste lubricating oil from various locations to a specialized recycling facility for subsequent processing.

[0004] At present, when waste lubricating oil is collected and processed, it is generally stored directly in oil barrels. For example, patent document CN218641471U discloses a lubricating oil storage tank, whose main structure includes a movable frame, a connecting shaft, rollers, an oil storage tank, a drain valve, a sealing cover, a refueling bucket, and a push handle. The movable frame is rotatably provided with a connecting shaft on both the front and rear sides, and rollers are provided on both the left and right ends of the connecting shaft. The upper part of the movable frame is provided with an oil storage tank, the bottom of the oil storage tank is provided with and connected to the drain valve, the top of the oil storage tank is screwed on and provided with a sealing cover, the middle of the sealing cover is provided with a refueling bucket, and also includes an oil extractor and a liquid level pipe. The sealing cover is provided with an oil extractor for extracting the lubricating oil stored in the oil storage tank near the refueling bucket, and the front side of the oil storage tank is provided with a liquid level pipe connected to the interior thereof.

[0005] It can be seen from the above-mentioned existing lubricating oil storage structure that it is mainly used for storing new lubricating oil after production; however, it is not suitable for temporary storage of waste lubricating oil, mainly because this storage structure mainly relies on the self-sedimentation of the lubricating oil to complete the sedimentation and accumulation of lubricating oil impurities after collecting the waste lubricating oil; in addition, since the waste lubricating oil needs to be centrally transported to a professional processing workshop for centralized purification, there will be vibration when the lubricating oil is transported to the interior of the workshop, which will cause the impurities after sedimentation to shake again, and the relative cleanliness of the lubricating oil introduced into the workshop equipment cannot be guaranteed. A large amount of residue filtering operations will be required later, which greatly increases the pre-process of lubricating oil treatment in the workshop, resulting in a decrease in treatment efficiency and a significant increase in treatment costs.

[0006] To this end, the present invention improves the early collection process of waste lubricating oil, effectively reducing the processing steps in the subsequent processing workshop. The waste lubricating oil storage and transfer container can effectively solve the problems existing in the existing technology. Utility Model Content

The following embodiments are only used to more clearly illustrate the present invention's technical solution and are therefore only examples and are not intended to limit the scope of protection of the present invention. Figure 1-Figure 5 As shown in .

[0031] Example 1: A waste lubricating oil transfer container comprises an oil storage barrel 1, a rigid support frame 2 is fixedly mounted on the bottom of the oil storage barrel 1, a plurality of universal wheel sets 3 are fixedly mounted on the bottom of the rigid support frame 2, a multi-stage combined oil filter is mounted inside the oil storage cavity 4 of the oil storage barrel 1, the bottom four corners of the multi-stage combined oil filter are supported on the bottom of the oil storage cavity 4 by lifting positioners, an oil outlet bellows 6 with an oil outlet control valve 5 is mounted at the center bottom of the oil storage barrel 1, and the oil outlet bellows 6 is mounted on the bottom of the oil storage cavity 4. The outlet end of the corrugated pipe 6 is arranged horizontally, and a sealing end cap is threadedly engaged with the upper outer wall of the oil storage barrel 1. An adjustable support member is mounted on the rigid support frame 2 outside each of the universal wheel assemblies 3. When the oil storage barrel 1 is in transit, the bottom of each adjustable support member is higher than the bottom of the universal wheel assemblies 3. When the oil storage barrel 1 is in vehicle transport, the bottom of each adjustable support member is lower than or flush with the bottom of the universal wheel assemblies 3. The waste lubricating oil transfer container of the present invention is supported by the universal wheel assemblies 3 at the bottom while also being able to be flexibly transferred. After the transfer is in place, the sealing end cover component is removed, and the waste lubricating oil is injected into the oil storage chamber 4 inside it through the external oil filling equipment. When the lubricating oil falls, it will continue to accumulate at the multi-stage combined oil filter and pass through the multi-stage filtration residue of the multi-stage combined oil filter to achieve the deposition of relatively clean lubricating oil at the bottom, and impurities of different particle sizes will be blocked inside the multi-stage combined oil filter. When the oil is filled, the sealing end cover component can be screwed on to achieve sealing. Before screwing on the sealing end cover component, when there are too many impurities, the multi-stage combined oil filter can be lifted out and cleaned as needed, and then placed back into the oil storage chamber 4 after cleaning.

[0032] In any of the above schemes, it is preferred that the multi-stage combined oil filter includes a large-diameter filter residue unit, a medium-diameter filter residue unit, and a small-diameter filter residue unit coaxially stacked in sequence from top to bottom inside the oil storage chamber 4; and a plurality of lifting position controllers are evenly spaced at the bottom of the small-diameter filter residue unit.

[0033] When filtering residue, the multi-stage combined oil filter relies on the large-diameter filter residue unit, the medium-diameter filter residue unit, and the small-diameter filter residue unit to grade and filter the large-diameter impurities, medium-diameter impurities, and small-diameter impurities in the oil to block the impurities.

[0034] Controlling the lifting height of the lifting position controller at the current bottom can control the height positions of the large-diameter filter residue unit, the medium-diameter filter residue unit, and the small-diameter filter residue unit at the top inside the oil storage chamber 4.

[0035] In any of the above schemes, it is preferred that the large-diameter filter residue unit includes a large-diameter annular cylinder 7, the upper part of the large-diameter annular cylinder 7 is folded inward to form a large-diameter guide portion 701, the bottom of the large-diameter annular cylinder 7 is horizontally folded inward to form a large-diameter supporting ring portion 702, and a large-diameter filter mesh disk 703 is detachably installed inside the large-diameter cavity 704 of the large-diameter annular cylinder 7 above the large-diameter supporting ring portion 702, the outer side wall of the large-diameter filter mesh disk 703 is pressed against the inner wall of the large-diameter cavity 704, the outer side of the bottom of the large-diameter filter mesh disk 703 is pressed against the top of the large-diameter supporting ring portion 702, and the surface of the large-diameter filter mesh disk 703 is provided with a plurality of large-diameter mesh holes.

[0036] In any of the above schemes, it is preferred that the medium-diameter filter residue unit includes a medium-diameter annular cylinder 8 abutting the bottom of the large-diameter annular cylinder 7, the upper part of the medium-diameter annular cylinder 8 is folded inward to form a medium-diameter guide portion 801, the bottom of the medium-diameter annular cylinder 8 is horizontally folded inward to form a medium-diameter supporting ring portion 802, and a medium-diameter filter mesh disk 804 is detachably installed inside the medium-diameter cavity 803 of the medium-diameter annular cylinder 8 above the medium-diameter supporting ring portion 802, the outer side wall of the medium-diameter filter mesh disk 804 is tightly abutted against the inner wall of the medium-diameter cavity 803, the outer side of the bottom of the medium-diameter filter mesh disk 804 abuts against the top of the medium-diameter supporting ring portion 802, and the surface of the medium-diameter filter mesh disk 804 is provided with a plurality of medium-diameter mesh holes, the aperture of the medium-diameter mesh holes is smaller than the aperture of the large-diameter mesh holes.

[0037] In any of the above schemes, it is preferred that the small-diameter filter residue unit includes a small-diameter annular cylinder 9 abutting the bottom of the medium-diameter annular cylinder 8, the upper part of the small-diameter annular cylinder 9 is folded inward to form a small-diameter guide portion 901, the bottom of the small-diameter annular cylinder 9 is horizontally folded inward to form a small-diameter supporting ring portion 902, and a small-diameter filter mesh disk 904 is detachably installed inside the small-diameter cavity 903 of the small-diameter annular cylinder 9 above the small-diameter supporting ring portion 902, the outer side wall of the small-diameter filter mesh disk 904 is pressed against the inner wall of the small-diameter cavity 903, the outer side of the bottom of the small-diameter filter mesh disk 904 is abutted against the top of the small-diameter supporting ring portion 902, and the surface of the small-diameter filter mesh disk 904 is provided with a plurality of small-diameter mesh holes, the aperture of the small-diameter mesh holes is smaller than the aperture of the medium-diameter mesh holes.

[0038] The large-diameter filter residue unit, medium-diameter filter residue unit, and small-diameter filter residue unit designed in this application respectively complete the blocking of particulate impurities in the waste lubricating oil according to the size of the particle size. Since the corresponding mesh holes on the large-diameter filter mesh disk 703, the medium-diameter filter mesh disk 804, and the small-diameter filter mesh disk 904 are continuously reduced, the larger particulate impurities will be accumulated on the top large-diameter filter mesh disk 703, the medium-diameter particulate impurities will be accumulated on the medium-diameter filter mesh disk 804, and the smaller impurities will be directly blocked and accumulated on the small-diameter filter mesh disk 904, thereby completing the three-stage filtration treatment of the waste lubricating oil.

[0039] In any of the above schemes, it is preferred that the lifting position controller includes a vertical internal screw tube 10 fixedly installed at the bottom of the small-diameter supporting ring 902, an internal thread is provided in the inner cavity of the vertical internal screw tube 10, a stainless steel lifting screw 11 is screwed into the inner thread of the inner cavity of the vertical internal screw tube 10, a stainless steel knob seat 12 is provided at the bottom of the stainless steel lifting screw 11, and the bottom of the stainless steel knob seat 12 abuts against the bottom of the oil storage chamber 4.

[0040] The lifting position controller controls the corresponding stainless steel lifting screw 11 to rotate as needed, so as to change its overall length, and finally drive the corresponding large-diameter filter residue unit, medium-diameter filter residue unit, and small-diameter filter residue unit above to achieve support at different heights.

[0041] In any of the above schemes, it is preferred that the adjustment support member includes a supporting stud 13 screwed into a threaded through hole at the bottom of the rigid support frame 2, the upper part of the supporting stud 13 is screwed into the central space 14 of the rigid support frame 2, and a ground connecting seat 15 is fixedly installed at the bottom of the supporting stud 13; when the oil storage barrel 1 is in a transit state, the bottom of each of the ground connecting seats 15 is higher than the bottom of the universal wheel group 3, and when the oil storage barrel 1 is in a vehicle transportation state, the bottom of each of the ground connecting seats 15 is lower than the bottom of the universal wheel group 3 or is flush with the bottom of the universal wheel group 3.

[0042] The adjustment support is mainly used to achieve stable support for the bottom of the entire waste lubricating oil transfer container when it is required to be transported on a vehicle, thereby reducing its shaking during transportation; when it is necessary to adjust the lifting and lowering of the ground connecting seat 15, the ground connecting seat 15 can be screwed together to drive the supporting stud 13 above it to achieve screwing and locking in the height direction, so that the bottom of the ground connecting seat 15 is lower than the bottom of the universal wheel group 3 or is flush with the bottom of the universal wheel group 3, thereby achieving the purpose of stable support.

[0043] In any of the above schemes, it is preferred that the sealing end cover component includes a screw-on sealing cover 16 threadedly mounted on the upper outer wall of the oil storage barrel 1, and a rubber sealing plug 17 is fixedly mounted at the bottom center of the screw-on sealing cover 16, and the outer wall of the rubber sealing plug 17 is sealed tightly against the inner wall of the oil storage chamber 4.

[0044] The sealing end cover component as a whole adopts a screw-on sealing method to seal the top opening of the entire oil storage chamber 4. The sealing is achieved by screwing in the rubber sealing plug 17, and the screw-on sealing cover 16 is used to achieve secondary sealing to improve the sealing effect.

[0045] In any of the above solutions, preferably, a plurality of operating handles 18 are fixedly screwed on the outer side wall of the screw-on sealing cover 16 .

[0046] The screwing operation handle 18 can save effort when screwing the sealing cover 16 outwards to remove it, thereby facilitating installation and removal of the sealing cover 16 .

[0047] In any of the above solutions, preferably, sliding handrails 19 are fixedly welded on the outer side walls of both sides of the oil storage barrel 1.

[0048] The pushing armrest 19 can facilitate the flexible displacement of the entire waste lubricating oil transfer container when the universal wheel set 3 at the bottom of the oil storage barrel 1 is in an active state.

[0049] Example 2: Compared with Example 1, the difference of this example is:

[0050] A transparent tempered glass 20 is sealed and installed at the middle window of the front side wall of the oil storage barrel 1.

[0051] The transparent tempered glass 20 allows for intuitive observation of the oil level and accumulation of impurities in the oil storage chamber 4 .

[0052] A hanging eye 21 is fixedly mounted on the center top of the large-diameter filter mesh disk 703 , the center top of the medium-diameter filter mesh disk 804 , and the center top of the small-diameter filter mesh disk 904 .

[0053] When it is necessary to take out the large-diameter filter residue unit, the medium-diameter filter residue unit, and the small-diameter filter residue unit respectively, the corresponding lifting earrings 21 can be lifted with the external hook, so that the corresponding large-diameter filter residue unit, the medium-diameter filter residue unit, and the small-diameter filter residue unit can be quickly taken out.

[0054] Specific working principle: The entire waste lubricating oil transfer container is supported by the universal wheel sets 3 at the bottom and can be flexibly transferred.

[0055] After the transfer is completed, the sealing end cover component is removed and waste lubricating oil is injected into the oil storage cavity 4 inside the sealing end cover through an external oil injection device.

[0056] As the lubricating oil falls, it will continuously accumulate at the multi-stage combined oil filter and pass through the multi-stage filtration residue of the multi-stage combined oil filter to deposit the relatively clean lubricating oil at the bottom, and impurities of different particle sizes will be blocked inside the multi-stage combined oil filter. When the oil is filled, the sealing end cover component can be screwed on to achieve sealing. Before screwing on the sealing end cover component, when there are too many impurities, the multi-stage combined oil filter can be lifted out as needed to complete cleaning, and then placed back into the oil storage chamber 4 after cleaning.

[0057] Since the corresponding mesh holes on the large-diameter filter mesh disk 703, the medium-diameter filter mesh disk 804, and the small-diameter filter mesh disk 904 are continuously reduced, larger particulate impurities will be accumulated on the top large-diameter filter mesh disk 703, medium-diameter particulate impurities will be accumulated on the medium-diameter filter mesh disk 804, and smaller impurities will be directly blocked and accumulated on the small-diameter filter mesh disk 904, thereby completing the three-stage filtration treatment of the waste lubricating oil.

[0058] After being loaded, the waste lubricating oil transfer container can be placed directly inside a transfer vehicle with the aid of a forklift, awaiting transport to the subsequent lubricating oil secondary processing workshop. Specifically, the large-diameter filter unit, medium-diameter filter unit, and small-diameter filter unit designed into this container can filter out particulate impurities in the waste lubricating oil based on their particle size.

[0059] From the above, it can be seen that the waste lubricating oil transfer container in the present invention can be flexibly moved as a whole to realize temporary storage of waste lubricating oil. After the lubricating oil is filled, the waste lubricating oil transfer container can be flexibly rotated by pushing it under the action of the universal wheel group 3 at the bottom; when the waste lubricating oil transfer container needs to be transferred, the various adjustment support parts can be quickly adjusted to make its bottom lower than the bottom of the universal wheel group 3 or flush with the bottom of the universal wheel group 3, thereby achieving support for the stability of the entire waste lubricating oil transfer container.

[0060] When using a waste lubricating oil transfer container to hold waste lubricating oil, the built-in multi-stage combined oil filter can be used to complete multi-stage filtration of impurities in the waste lubricating oil. The impurities will be blocked by the multi-stage combined oil filter in the middle and upper parts of the oil storage chamber 4, ensuring that most impurities do not enter the lubricating oil at the bottom, ensuring the relative cleanliness of the lubricating oil discharged to the outside; the large-diameter filter mesh plate 703, the small-diameter filter mesh plate 904, and the small-diameter filter mesh plate 904 in the multi-stage combined oil filter can all be quickly disassembled and removed, which is convenient for subsequent regular cleaning and reuse.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
