[0036] When filtering a liquid, the filtering method in the related art is to filter one by one with filter meshes, but the filtering effect is generally average and the filtering quality is poor. This application provides a multi-stage filtering device that can perform multi-stage filtering on the liquid to improve the filtering quality, and during the filtering process, the liquid flows along an S-shaped flow path, so that a better filtering effect can be achieved.

[0037] Such asFigures 1 to 3 As shown in Figures 1 to 3 , a multi - stage filtering device 1 provided by the present application includes:

[0038] A box body 11, the box body 11 having a liquid inlet 111 and a liquid outlet 112;

[0039] N partition plates 12, the N partition plates 12 being arranged at intervals in the box body 11 along a first direction, so as to divide the box body 11 into N + 1 filtering chambers 121. The first filtering chamber 121 is communicated with the liquid inlet 111, the (N + 1)th filtering chamber 121 is communicated with the liquid outlet 112. Each partition plate 12 has an opening 122, and a filtering device 13 is arranged at the opening 122. The openings 122 on two adjacent partition plates 12 are respectively arranged on both sides along a second direction, so that the liquid forms an S - shaped flow path in the box body 11;

[0040] Any two of the first direction, the second direction and the vertical direction are perpendicular to each other.

[0041] In this embodiment, the liquid can be oils, such as camellia oil, petroleum, etc., or other types of liquids.

[0042] In this embodiment, when the box body 11 is placed on a horizontal ground, the first direction is the length direction of the box body 11, the second direction is the width direction of the box body 11, and the vertical direction can be the height direction of the box body 11.

[0043] A multi - stage filtering device 11 provided by the present application includes a box body 11, N partition plates 12 and N filtering devices 13. The N partition plates 12 and the N filtering devices 13 are arranged in the box body 11. The N partition plates 12 are arranged at intervals in the box body 11 along a first direction, so as to divide the box body 11 into N + 1 sequentially arranged filtering chambers 121. The first chamber in the N + 1 filtering chambers 121 along the first direction is connected to the liquid inlet 111 to receive the liquid to be filtered. After the liquid to be filtered enters the first filtering chamber 121, it will be first filtered by the filtering device 13 arranged at the opening 122 of the partition plate 12. The liquid after the first - stage filtration will flow into the next filtering chamber 121. The openings 122 for arranging the filtering devices 13 on two adjacent partition plates 12 are respectively arranged on both sides along a second direction. Thus, the flow path of the liquid passing through multiple filtering chambers for filtration is an S - shaped flow path, which makes the flow path of the liquid longer, thereby improving the filtering effect, facilitating the maintenance of the filtering device 13, and increasing the service life of the filtering device 13. After passing through multiple filtering devices 13 through the S - shaped flow path, the liquid flows into the (N + 1)th filtering chamber 121, and the (N + 1)th filtering chamber 121 is communicated with the liquid outlet 112, so as to flow out the filtered liquid to achieve multi - stage filtration of the liquid.

[0044] Therefore, the multi-stage filtering device 1 provided by the present application divides the box body 11 into N + 1 filtering chambers 121 by arranging N partitions 12 in the box body 11. A filtering device 13 is provided at the opening 122 of each partition 12. The structure is compact, so that the liquid can be filtered N times through N filtering devices 13 to achieve multi-stage filtering. The openings 122 on two adjacent partitions 12 are respectively arranged on both sides along the second direction, so that the liquid forms an S-shaped flow path in the box body 11, which can further improve the filtering quality and efficiency, and is also convenient for maintaining the filtering device 13 and prolonging the service life of the filtering device 13.

[0045] As Figure 3 shown, in the embodiment of the present application, the heights of the N openings 122 in the vertical direction along the first direction increase sequentially from the liquid inlet 111 end to the liquid outlet 112 end.

[0046] In this embodiment, N partitions 12 are arranged in the box body 11 to divide the box body 11 into N + 1 filtering chambers 121. An opening 122 is provided on each partition 12, and a filtering device 13 is provided at the opening 122. Thus, the liquid in the previous filtering chamber 121 enters the next filtering chamber 121 after being filtered by the filtering device 13. Therefore, the liquid is filtered successively through multiple filtering devices 13 to achieve multi-stage filtering with good filtering effect. The heights of the multiple openings 122 arranged in sequence from the liquid inlet 111 end to the liquid outlet 112 end increase sequentially in the vertical direction, that is, the height of the opening 122 on the first partition 12 is the lowest, and the height of the opening 122 on the last partition 12 is the highest. Since the filtering device 13 is provided on the opening 122, the height of the filtering device 13 on the first partition 12 is the lowest, and the height of the filtering device 13 on the last partition 12 is the highest. Thus, while filtering the liquid, the foam on the liquid surface and the oil residue at the bottom can be effectively removed, realizing the purification function.

[0047] As Figure 2 and Figure 3 shown, in the embodiment of the present application, two adjacent partitions 12 are in a V-shaped structure, so that the filtering chamber 121 formed by the two adjacent partitions 12 is in a triangular prism structure.

[0048] In this embodiment, N partitions 12 are arranged in the box body 11 to divide the box body 11 into N + 1 filtering chambers 121. The extending directions of two adjacent partitions 12 are different, and two adjacent partitions 12 intersect with each other. A V-shaped structure is formed between two adjacent partitions 12, so that the filtering chamber 121 formed by two adjacent partitions 12 is a triangular prism structure, thereby more filtering chambers 121 can be formed in the box body 11, enabling the liquid to be filtered more times and improving the filtering effect. And two adjacent partitions 12 intersect with each other, that is, one partition 12 extends along the width direction of the box body 11, namely the second direction, and the other partition 12 is an inclined partition 12, so that the flow path of the liquid can be more curved, making the flow path of the liquid longer, and further improving the filtering effect and filtering quality. And the inclined partition 12 can collect the sediment in the liquid, further improving the filtering effect.

[0049] As Figure 3 and Figure 4 shown, in the embodiment of the present application, the filtering device 13 is plugged and unplugged at the opening 122 on the partition 12.

[0050] In this embodiment, it is thus convenient to disassemble the filtering device 13, facilitating replacement and maintenance.

[0051] In the embodiment of the present application, a clamping groove 123 is arranged on the side wall at the opening 122 of the partition 12. The filtering device 13 is a filter mesh plate, and the filter mesh plate is plugged and unplugged with the clamping groove 123.

[0052] In this embodiment, the side wall at the opening 122 of each partition 12 is a double-layer structure, and the double-layer structures are spaced apart to form the clamping groove 123. The filter mesh plate can be inserted into the clamping groove 123 to realize the plugging and unplugging connection between the filter mesh plate and the clamping groove 123, thus facilitating the disassembly of the filtering device 13 and facilitating replacement and maintenance.

[0053] As Figures 1 to 3 shown, in the embodiment of the present application, it further includes: N + 1 liquid level detection devices 14, and each liquid level detection device 14 is communicated with a filtering chamber 121 to be used for detecting the liquid level height in the corresponding filtering chamber 121.

[0054] In this embodiment, the multi-stage filtering device 1 includes N partition plates 12 and N + 1 liquid level detection devices 14. The N partition plates 12 divide the box body 11 to form N + 1 filtering chambers 121. One liquid level detection device 14 is correspondingly arranged in each filtering chamber 121. Each liquid detection device includes a first pipeline extending into the corresponding filtering chamber 121 and a second pipeline located outside. The first pipeline is communicated with the second pipeline, and the liquid level height in the second pipeline is the same as the liquid level height of the liquid in the filtering chamber 121, so that it can be judged whether the filtering device 13 is blocked according to the liquid level height.

[0055] As Figures 1 to 3 shown, in the embodiment of the present application, the liquid level detection device 14 includes a liquid level display part located outside the box body 11, which is used to display the liquid level height in the corresponding filtering chamber 121.

[0056] In this embodiment, the liquid level display part is the second pipeline. The liquid level display part is arranged outside the corresponding filtering chamber 121, so that the liquid level height in the corresponding filtering chamber 121 can be directly viewed through the liquid level display part, which is convenient for the user to view and use.

[0057] As Figures 1 to 3 shown, in the embodiment of the present application, a slag discharge port 15 is further arranged at the bottom of each filtering chamber 121 along the vertical direction.

[0058] In this embodiment, each filtering chamber 121 is provided with an independent slag discharge port 15, so that slag can be discharged more efficiently. The slag discharge port 15 is also connected with a valve through a pipeline. Each slag discharge port 15 is connected with a valve, so that it can be separately spaced. The end of the slag discharge pipeline is also connected with a centrifugal slag filtering device to further separate the slag.

[0059] In the embodiment of the present application, it further includes: variable frequency pumps are connected to both the liquid inlet 111 and the liquid outlet 112 to control the liquid inlet or outlet speed.

[0060] In this embodiment, variable frequency pumps can be arranged on the pipelines of both the liquid inlet 111 and the liquid outlet 112, so that the liquid inlet speed and the liquid outlet speed can be flexibly controlled, the filtering speed can be increased, the liquid can be automatically filtered multiple times, labor can be saved, and the filtering quality and use efficiency can be improved.

[0061] As Figures 1 to 3 shown, in the embodiment of the present application, it further includes:

[0062] A base 17, and the base 17 is arranged below the box body 11 to facilitate the support and movement of the box body 11.

[0063] In this embodiment, the multi-stage filtering device 1 includes a base 17 and a box body 11. The box body 11 is fixedly arranged on the base 17. The base 17 has high structural strength, which can facilitate the transfer of the whole by handling tools such as hydraulic forklifts, thus facilitating the overall moving of the box body 11. Above the box body 11, a cover plate 113 is provided corresponding to each filtering chamber 121. The cover plate 113 can be detached separately, which is convenient for opening the cover plate 113 when the filtering device 13 is blocked to clean the filtering device 13, facilitating maintenance and achieving the effects of sealing and dust prevention.
