It should be noted that a filter box body 200 is provided inside the main filter box 100, and the filter box body 200 can filter the liquid entering the main filter box 100, and the filtered liquid will enter the return connection hose 002 through the connection port 110. In addition, in the present embodiment, the filter box body 200 and the main filter box 100 are a split structure, and the filter box body 200 can be installed inside the main filter box 100 when in use. When there are too many impurities inside the filter box body 200, the filter box body 200 can be taken out for cleaning.

[0038] It should be noted that there is a space between the filter box body 200 and the main filter box 100. Figure 6 As shown, the reserved space is used to cache the filtered liquid and facilitate the filtering of the liquid by the filter box body 200. Moreover, the shape and size of the filter box body 200 match the main filter box 100 to prevent liquid from entering the return connection hose 002 without being filtered.

[0039] Specifically, in order to prevent impurities in the oiling box body 001 from entering the return connecting hose 002 from the return pipe port 011, the present application provides a filtering device installed at the return pipe port 011, the filtering device includes an outer main body filter box 100 and an internal filter box body 200, the main body filter box 100 can receive liquid flowing out of the return pipe port 011, and the bottom is connected to the return connecting hose 002, and a filter box body 200 is arranged inside the main body filter box 100 for filtering the liquid entering the main body filter box 100, the filter box body 200 will filter the liquid that is about to enter the return connecting hose 002, therefore, such a setting can effectively prevent impurities in the oiling box body 001 from clogging the return connecting hose 002; in addition, the filter box body 200 and the main body filter box 100 are of a split design, which is also convenient for cleaning the filter box body 200, thereby extending its service life and reducing the cost of use.

[0040] Preferably, the main filter box 100 is a cylindrical structure, an upper side of which is provided with an opening having the same diameter as the main filter box 100, and a cylindrical connection port 110 extending downward is provided at the center of the bottom of the main filter box 100.

[0041] like Figure 2As shown, in this embodiment, the main filter box 100 is preferably a cylindrical structure, and its upper end is not sealed, and the lower end is provided with a bottom surface, but a connection port 110 is provided in the center of the bottom surface, and the connection port 110 extends vertically downward, and is configured to be a cylindrical structure that is convenient for inserting the return connection hose 002, so that the upper end of the main filter box 100 can easily receive the liquid flowing out of the return pipe port 011; it should be noted that the diameter of the main filter box 100 needs to be larger than the diameter of the return pipe port 011, so as to avoid leakage of the liquid flowing out of the return pipe port 011, and the diameter of the main filter box 100 The slightly larger size also facilitates the installation of the main filter box 100, and its upper end opening can easily and completely include the return pipe opening 011; in addition, the diameter of the connection port 110 also needs to be set according to the diameter of the return connection hose 002, and in order to enable the connection port 110 and the return connection hose 002 to be firmly connected, an annular groove can be set on the circumference of the connection port 110. When the connection port 110 is inserted into the return connection hose 002, the connection port 110 and the return connection hose 002 can be fastened by setting a fastening clamp, and the fastening clamp can be clamped in the annular groove, so that it is not easy to lose the fastening effect due to sliding.

[0042] Of course, the diameter of the main filter box 100 can also be adjusted according to actual needs, as long as it can meet the requirements.

[0043] Preferably, the main filter box 100 is connected to the lower side of the oiling box body 001 via a suspension rod 120 installed on the side wall thereof, and two suspension rods 120 are arranged in parallel.

[0044] In this embodiment, the main filter box 100 is suspended on the lower side of the oiling box body 001 by a suspension rod 120. The suspension rod 120 is installed on the circumferential side wall of the main filter box 100 and strengthens the stability of the main filter box 100. Two suspension rods 120 are set at the same time.

[0045] Preferably, a quick-release fixing connecting plate 130 is fixedly installed at the end of the suspension rod 120 facing away from the main filter box 100, and a quick-release fork 131 is provided on the side of the quick-release fixing connecting plate 130. The quick-release fork 131 is used to cooperate with the butterfly nut 012 on the lower side of the oiling box body 001 to fix the main filter box 100.

[0046] like Figure 2 and Figure 5As described, a quick-release fixing connecting plate 130 is fixedly installed at the ends of the two suspension rods 120. The quick-release fixing connecting plate 130 is a plate-like structure, and a quick-release fork 131 is provided on its side. When the main filter box 100 is installed, the main filter box 100 can be suspended on the butterfly nut 012 on the lower side of the oil-coated box body 001 through the quick-release fork 131. When the main filter box 100 needs to be disassembled and cleaned, it is only necessary to loosen the butterfly nut 012, and then the main filter box 100 can be quickly removed. This arrangement greatly improves the convenience of installation and disassembly of the filter device.

[0047] Preferably, a placement groove 140 is provided on the circumference of the upper opening of the main filter box 100 .

[0048] like Figure 2 As shown, a circle of annular placement grooves 140 are provided on the circumference of the upper opening of the main filter box 100 , and the depth of the placement grooves 140 can be set according to actual conditions as long as it can play the role of installing the filter box body 200 .

[0049] Preferably, the filter box body 200 is a cylindrical structure, a filter screen 210 is provided on the bottom surface of the filter box body 200 , and a plurality of filter holes are provided on the side wall of the filter box body 200 .

[0050] Specifically, Figure 3 and Figure 4 As shown, the structure of the filter box body 200 is also a cylindrical structure in order to adapt to the shape of the main filter box 100, and a plurality of filter holes are arranged on its side wall, and a filter screen 210 is arranged at the bottom of the filter box body 200. The filter screen 210 can be a separate structure from the filter box body 200, or an integrated structure. This article does not make any specific restrictions, as long as the filtering effect can be achieved.

[0051] Preferably, the upper circumferential surface of the filter box body 200 is provided with a box body flange 220 , and the box body flange 220 is used to cooperate with the placement groove 140 to support the filter box body 200 .

[0052] like Figure 3 As described above, an annular box body flange 220 is provided on the upper circumferential surface of the filter box body 200, and the size of the box body flange 220 is the same as the size of the mounting groove 140 on the main filter box 100. In this way, when the filter box body 200 is installed inside the main filter box 100, it can be firmly fixed therein and is not prone to shaking.

[0053] Preferably, the filter screen 210 is provided with a plurality of filter holes with different apertures, and the diameters of the plurality of filter holes on the side wall of the filter box body 200 are the same.

[0054] like Figure 3 and Figure 4As shown, in the present embodiment, the filter holes on the filter screen 210 have different diameters, while the filter holes on the filter box body 200 have uniform diameters; since the filter box body 200 and the main filter box 100 are mutually nested structures, the gap between the side walls thereof is relatively small, and therefore, the filtering function is mainly performed by the filter screen 210 at the bottom, and the filter holes of the bottom filter screen 210 have different diameters, which is more suitable for the application scenario of the present application, i.e., smaller particles are allowed to enter the return connection hose 002 to prevent the liquid in the oiling box body 001 from being unable to pass smoothly through the filter holes due to excessive concentration or impurities.

[0055] Of course, in this embodiment, the filter holes on the side wall of the filter box body 200 preferably have the same diameter. The diameter of the filter holes can also be adjusted according to actual conditions. This article does not make a specific limitation as long as the expected filtering effect can be achieved.

[0056] Preferably, a box handle 230 is fixed to the inner side wall of the filter box body 200 , and the box handle 230 is used to facilitate taking out the filter box body 200 from the main filter box 100 .

[0057] It can be understood that in order to clean the filter box body 200 in time when there are too many impurities, a box handle 230 is fixed to the inner wall of the filter box body 200. When the filter box body 200 needs to be cleaned, the filter box body 200 can be directly taken out through the handle, which greatly improves the convenience of cleaning the filter device.

[0058] Preferably, a pressure sensor is installed in the placement groove 140, and an alarm is set on the outer wall of the main filter box 100. The alarm is connected to the pressure sensor. The pressure sensor can detect the pressure of the filter box body 200, so that when the weight of impurities inside exceeds a preset value, a signal is transmitted to the alarm to activate the alarm to prompt the filter box body 200 to be cleaned.

[0059] This article also provides an embodiment, that is, a pressure sensor is installed inside the accommodation groove 140, and an alarm connected to the pressure sensor is set outside the main filter box 100. In this way, when there are too many impurities in the filter box body 200, a large pressure will be exerted on the pressure sensor, thereby triggering the alarm to remind the staff to clean the filter box body 200.

[0060] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0062] The above is a detailed introduction to the embodiments provided by the utility model.
