[0026] It should be understood that various modifications can be made to the embodiments disclosed herein. Therefore, the above description should not be regarded as a limitation, but only as an example of the embodiments. Those skilled in the art will think of other modifications within the scope and spirit of the present invention.

[0027] The drawings included in the specification and forming a part of the specification illustrate embodiments of the present invention, and together with the general description of the present invention given above and the detailed description of the embodiments given below are used to explain the principles of the present invention.

[0028] These and other features of the present invention will become apparent from the following description of the preferred forms of the embodiments given by way of non-limiting example with reference to the drawings.

[0029] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art can surely implement many other equivalent forms of the present invention, which have the features as described in the claims and thus are all within the protection scope defined thereby.

[0030] When combined with the drawings, in view of the following detailed description, the above and other aspects, features and advantages of the present invention will become more apparent.

[0031] Specific embodiments of the present invention will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the disclosed embodiments are merely examples of the present invention, which can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present invention with unnecessary or redundant details. Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but merely as a basis and representative basis for the claims to teach those skilled in the art to use the present invention in substantially any suitable detailed structure in a variety of ways.

[0032] In a first aspect of the present invention, an oil recovery device is provided, which includes a liquid inlet pipe 1, a filtering assembly 2, and a collection tank 3. The filtering assembly 2 is installed in the collection tank 3. The filtering assembly 2 includes an outer cylinder 21 and an inner cylinder 22. The inner cylinder 22 is installed inside the outer cylinder 21. There is a gap between the bottom of the inner cylinder 22 and the bottom of the outer cylinder 21 to form a first cavity 23. A liquid passage is provided inside the inner cylinder 22. The liquid passage penetrates through the upper and lower ends of the inner cylinder 22 and is respectively communicated with the liquid inlet pipe 1 and the first cavity 23. A filtering inlet communicated with the first cavity 23 is opened at the bottom of the inner cylinder 22. A filtering outlet communicated with the collection tank 3 is opened at a position near the top of the inner cylinder 22. Filtering materials are filled in the inner cylinder 22.

[0033] Combined Figure 1 、 Figure 2 and Figure 3 As shown, the inner cylinder 22 is arranged inside the outer cylinder 21. A first cavity 23 is formed between the bottom of the inner cylinder 22 and the inner wall of the bottom of the outer cylinder 21. A filtering inlet is provided at the bottom end of the inner cylinder 22, and a filtering outlet is provided at the top end of the inner cylinder 22. Filtering materials are filled inside the inner cylinder 22. The oil enters the first cavity 23 through the liquid inlet pipe 1 and the liquid passage. The oil gradually accumulates and fills the first cavity 23, and then enters the inner cylinder 22 through the filtering inlet. The oil filtered by the filtering materials overflows from the filtering outlet near the top end of the inner cylinder 22 and flows down from the periphery of the outer cylinder 21 and enters the collection tank 3.

[0034] In the grease recovery device of the present utility model, the grease to be recovered enters the first cavity 23 formed at the bottom of the inner cylinder 22 and the bottom of the outer cylinder 21 through the liquid inlet pipe 1. The grease gradually accumulates in the first cavity 23, and then the grease enters the inner cylinder 22 through the filtration inlet and is filtered by the filter material. The filtered grease overflows from the filtration outlet and flows down along the periphery of the outer cylinder 21 and enters the collection tank 3, realizing the functions of filtering and collecting grease. Since the grease accumulates in the first cavity 23 and then moves upward through the inner cylinder 22 and the filtration outlet, it can avoid the impact on the filter material when the grease directly enters the inner cylinder 22, enabling the grease to pass through the filter material in the inner cylinder 22 at a slower speed, making the filter material fully contact with the grease, improving the filtration effect of impurities in the grease, and having high practicability in the process of recycling grease.

[0035] Furthermore, it further includes a lifting component 4. An installation cylinder 223 penetrating the upper and lower ends of the inner cylinder 22 is provided on the inner cylinder 22. The lifting component 4 is installed in the installation cylinder 223 and the first cavity 23. The lifting component 4 has the liquid channel. The liquid inlet pipe 1 is movably installed at the top of the lifting component 4 and is communicated with the liquid channel. An liquid outlet 411 communicating the liquid channel and the first cavity 23 is provided on the lifting component 4 located in the first cavity 23.

[0036] Combined with Figures 1 to 3 As shown, the liquid inlet pipe 1 is movably installed at the top of the lifting component 4 and is communicated with the liquid channel in the lifting component 4. The bottom part of the lifting component 4 is located in the first cavity 23, and it is provided with the liquid outlet 411 to communicate the liquid channel and the first cavity 23, so that the grease enters the first cavity 23 through the liquid channel and the liquid outlet 411 to be distributed and accumulated. Preferably, the liquid outlet 411 can be a plurality of through holes arranged evenly, enabling the grease to accumulate more evenly and quickly in the first cavity 23, which is helpful for the grease filtration process.

[0037] Furthermore, the lifting component 4 includes a liquid distribution seat 41, a connecting pipe 42, a movable pipe 43, an elastic member 44, and a connecting ring 45. The liquid distribution seat 41 is located in the first cavity 23. The liquid distribution seat 41 has a hollow second cavity 412. The liquid outlet 411 is provided on the side wall of the liquid distribution seat 41. The connecting pipe 42 is installed on the liquid distribution seat 41 and is communicated with the second cavity 412. The movable pipe 43 is telescopically installed in the connecting pipe 42. The connecting ring 45 is installed at the top of the movable pipe 43. The elastic member 44 is sleeved on the outer periphery of the connecting pipe 42 and the movable pipe 43 and is located between the connecting ring 45 and the liquid distribution seat 41. The connecting ring 45, the movable pipe 43, the connecting pipe 42, and the second cavity 412 are sequentially communicated to form the liquid channel.

[0038] Combined Figure 1 、 Figure 2 and Figure 3 As shown, the liquid separation seat 41 is generally cylindrical, with a hollow interior forming a second cavity 412. A plurality of through holes are evenly opened on the side wall of the liquid separation seat 41 as liquid outlets 411. The connecting pipe 42 is fixedly installed on the liquid separation seat 41 (the two can be integrally connected or tightly connected by other means). The connecting pipe 42 communicates with the second cavity 412. The outer diameter of the movable pipe 43 is matched with the inner diameter of the connecting pipe 42, so that the movable pipe 43 can telescopically move. The top of the movable pipe 43 is fixedly connected and communicates with the connecting ring 45. The elastic member 44 is a spring, sleeved on the outer peripheries of the connecting pipe 42 and the movable pipe 43, and is respectively connected to the liquid separation seat 41 and the connecting ring 45. When the grease passes through the liquid inlet pipe 1, the connecting ring 45, the movable pipe 43 and the connecting pipe 42, it will impact the bottom wall of the liquid separation seat 41. The elastic member 44 provides a certain pulling force to buffer the impact of the grease, so that the flow rate of the grease slows down when it enters the first cavity 23 through the liquid outlet 411, which is beneficial to the accumulation of the grease in the first cavity 23.

[0039] In addition, the collection tank 3 includes a tank body 31 and a sealing cover 32. The top of the tank body 31 is open, and the sealing cover 32 is installed on the top of the tank body 31. One end of the liquid inlet pipe 1 is connected to the liquid passage, and the other end of the liquid inlet pipe 1 extends out of the sealing cover 32. When assembling the tank body 31 and the sealing cover 32, usually the liquid inlet pipe 1 needs to be installed with the sealing cover 32 first, and components such as the filtering assembly 2 and the lifting assembly 4 are loaded into the tank body 31. Finally, the sealing cover 32 is hermetically connected to the tank body 31. At this time, due to reasons such as dimensional design errors, the liquid inlet pipe 1 will press the elastic member 44 through the connecting ring 45, causing the telescopic movement between the movable pipe 43 and the connecting pipe 42, thereby avoiding the influence of errors on the assembly process.

[0040] Optionally, a ventilation pipe 322 is provided on the sealing cover 32. When the grease enters the first cavity 23 through the liquid inlet pipe 1 and the liquid passage, the gas pressure in the collection tank 3 increases, and pressure balance needs to be carried out through the ventilation pipe 322.

[0041] Preferably, a connecting groove 451 for connecting the bottom of the liquid inlet pipe 1 is provided at the top of the connecting ring 45.

[0042] Combined Figure 3 As shown, a connecting groove 451 is opened at the top of the connecting ring 45, so that the bottom of the liquid inlet pipe 1 is inserted into the connecting groove 451. In this way, it is convenient for the assembly between the liquid inlet pipe 1 and the connecting ring 45, and at the same time, it is beneficial to connect the liquid inlet pipe 1 and the movable pipe 43 through the connecting ring 45.

[0043] Further, the filtration inlet includes a plurality of first liquid inlet holes 221 formed at the bottom of the inner cylinder 22, the filtration outlet includes a plurality of first liquid outlet holes 224 arranged along the circumferential direction of the inner cylinder 22, and a first through groove 211 communicating the first liquid outlet holes 224 and the collection tank 3 is provided at a position near the top of the outer cylinder 21.

[0044] As shown in combination with Figure 2 a plurality of first liquid inlet holes 221 are provided at the bottom of the inner cylinder 22 as the filtration inlet, and a plurality of first liquid outlet holes 224 are arranged along the circumferential direction at the top of the inner cylinder 22 as the filtration outlet. As shown in combination with Figure 2 and Figure 4 a plurality of first through grooves 211 are provided at a position near the top of the outer cylinder 21 along the circumferential direction of the outer cylinder 21 to communicate with the first liquid outlet holes 224. The grease enters the inner cylinder 22 through the first liquid inlet holes 221 and is filtered by the filtering material, then flows out through the first liquid outlet holes 224, and finally falls into the collection tank 3 through the first through grooves 211.

[0045] Preferably, as shown in combination with Figure 2 the filtration outlet further includes a plurality of second liquid outlet holes 222 formed at the top of the inner cylinder 22. When there is a large amount of grease, the filtration efficiency is relatively low only through the first liquid outlet holes 224. Therefore, the second liquid outlet holes 222 and the first liquid outlet holes 224 can improve the filtration efficiency.

[0046] Further, an annular first connecting edge 311 is provided at the opening of the tank body 31, the sealing cover 32 has a second connecting edge 321 that cooperates with the first connecting edge 311, and an annular third connecting edge 213 is provided at the top edge of the outer cylinder 21. The first connecting edge 311, the third connecting edge 213, and the second connecting edge 321 are sequentially connected by fasteners.

[0047] As shown in combination with Figure 1 and Figure 4 a first connecting edge 311 similar to a flanging structure is provided at the opening of the tank body 31, a second connecting edge 321 is provided on the sealing cover 32, and a third connecting edge 213 is provided on the outer cylinder 21. The first connecting edge 311, the third connecting edge 213, and the second connecting edge 321 are tightly connected by fasteners, thereby completing the assembly, which is beneficial to maintaining the sealing performance of the collection tank 3.

[0048] Further, the side wall of the outer cylinder 21 and the third connecting edge 213 are connected by connecting spokes 212. A plurality of the connecting spokes 212 are arranged at intervals along the circumferential direction of the outer cylinder 21, and a second through groove 214 is formed between two adjacent connecting spokes 212 to communicate the second liquid outlet holes 222 and the collection tank 3.

[0049] As shown in combination withFigure 2 and Figure 4 As shown, the side wall of the outer cylinder 21 is connected to the inner wall of the third connecting edge 213 through the connecting spokes 212, and thus is installed and fixed through the third connecting edge 213. The plurality of connecting spokes 212 are arranged at intervals in the circumferential direction of the outer cylinder 21. The intervals between adjacent connecting spokes 212 form the second through groove 214. The filtered grease flowing out from the second liquid outlet hole 222 will flow around the outer cylinder 21 and then fall into the collection tank 3 through the second through groove 214.

[0050] In this way, the outer cylinder 21 can be installed and fixed, improving the stability of the outer cylinder 21, and at the same time, it will not affect the process of the filtered grease entering the collection tank 3.

[0051] Furthermore, a support column 24 is also provided in the first cavity 23. One end of the support column 24 is connected to the bottom wall of the outer cylinder 21, and the other end of the support column 24 is connected to the bottom wall of the inner cylinder 22.

[0052] Combined with Figure 2 As shown, there can be a plurality of support columns 24, which are arranged in the first cavity 23, and their two ends respectively abut against the outer wall of the bottom end of the inner cylinder 22 and the inner wall of the bottom end of the outer cylinder 21, thus forming a supporting effect.

[0053] In this way, through the supporting effect of the support column 24, it is ensured that the first cavity 23 has enough space for the grease to accumulate and spread out, so as to filter the grease more fully.

[0054] The present utility model also provides a vehicle, including the grease recovery device described above.

[0055] In the vehicle of the present utility model, the grease recovery device is installed. The grease to be recovered on the vehicle enters the first cavity 23 formed by the bottom of the inner cylinder 22 and the bottom of the outer cylinder 21 through the liquid inlet pipe 1. The grease gradually accumulates in the first cavity 23, and then the grease enters the inner cylinder 22 through the filtration inlet and is filtered by the filtering material. The filtered grease overflows from the filtration outlet and flows down from the periphery of the outer cylinder 21 into the collection tank 3, realizing the functions of filtering and collecting the grease; since the grease accumulates in the first cavity 23 and then moves upward through the inner cylinder 22 and the filtration outlet, it is possible to avoid the impact on the filtering material when the grease directly enters the inner cylinder 22, so that the grease passes through the filtering material in the inner cylinder 22 at a slower speed, enabling the filtering material to be in full contact with the grease, improving the filtering effect on the impurities in the grease, and having high practicability in the process of recycling the grease.

[0056] In the above embodiments of the present utility model, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0057] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways, rotated 90 degrees or in other orientations, and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0058] In addition to the above, it should also be noted that the "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in connection with that embodiment being included in at least one embodiment generally described in this application.
