[0019] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, and the present application is not limited to the embodiments described here.

[0020] Figure 1-3 The structure diagram of an embodiment of the utility model is shown. Figure 1-3 It can be seen that the fluid filtering device 100 includes a housing 110 , a guide pipe 120 , a filtering device 130 , an automatic cleaning device 140 and a dirt collecting device 150 .

[0021] The housing 110 has a first end face 111 and a second end face 112 at both ends, and the housing 110 has at least two opposite side faces connecting the first end face 111 and the second end face 112. The housing 110 is hollow inside to form a fluid channel 113. The first end face 111, the second end face 112 and the fluid channel 113 are on the same axis. The fluid channel 113 extends outwards along the axis toward the first end face 111 and the second end face 112 to form a water inlet 1131 and a water outlet 1132.

[0022] In one example, the water inlet 1131 and the water outlet 1132 may be provided with threaded openings or snap-fit ​​buckles for connection with external pipes, and may also be connected with external pipes through a reducer adapter.

[0023] The cross section of the housing 110 may be in various shapes. For example, the cross section of the housing 110 may be rectangular, hexagonal, octagonal or drum-shaped, etc. However, the housing 110 is not limited to any of the above shapes, and it may be changed according to actual needs to adapt to different requirements.

[0024] Reference Figure 3 , the side wall of the housing 110 is further provided with a side opening 114, and the side wall of the housing 110 extends outward at the side opening 114 in a direction perpendicular to the axis of the fluid channel 113 to form a direction conduit 1141. The direction conduit 1141 is used to guide the direction of the fluid flowing into the water inlet 1131, and plays a role in fixing the sewage collecting device 150.

[0025] The guide tube 120 is used to guide the flow direction of the fluid in the fluid channel 113. Figure 3 As shown, the guide tube 120 is coaxially arranged with the direction guide tube 1141, and its outer diameter is smaller than the inner diameter of the direction guide tube 1141. One end of the guide tube 120 is connected to the inner wall of the housing 110, and the other end extends into the direction guide tube 1141.

[0026] On the side of the guide pipe 120 facing the water outlet 1132, the inner wall of the shell 110 extends from the side opening 114 to be connected to the guide pipe 120, which closes the path for the fluid to flow directly from the direction conduit 1141 to the fluid channel 113; the guide pipe 120 is provided with an opening on the side facing the water outlet 1132, and the opening is communicated with the fluid channel 113, so as to guide the fluid to flow from the guide pipe 120 into the fluid channel 113 in the direction toward the water outlet 1132, and the diameter of the opening is less than or equal to the diameter of the fluid channel 113.

[0027] On the side of the guide tube 120 facing the water inlet 1131 , there is a gap between the inner wall of the directional conduit 1141 and the outer wall of the guide tube 120 , forming a channel that can guide the fluid to flow from the water inlet 1131 toward the directional conduit 1141 .

[0028] It can be seen that the setting of the guide pipe 120 prevents the water flow from flowing directly from the water inlet 1131 to the water outlet 1132 via the fluid channel 113, but flows from the water inlet 1131 into the direction conduit 1141, then flows from the direction conduit 1141 into the guide pipe 120, then flows from the guide pipe 120 into the fluid channel 113, and finally flows out from the water outlet 1132. This structural design for guiding the swirling flow of fluid provides a space for the filter device 130 described below to fully contact with the fluid, thereby increasing the filtering effect within a limited space.

[0029] A portion of the filter device 130 is rotatably disposed in the guide pipe, and another portion is disposed in the dirt collecting device 150 to filter out impurities in the fluid. It should be understood that the filter device 130 may also be entirely disposed in the guide pipe 120 or the dirt collecting device 150 .

[0030] The automatic cleaning device 140 is provided with a driving unit 141. When the filter device needs to be cleaned, the driving unit 141 drives the filter device 130 to rotate, generating sufficient centrifugal force to remove impurities in the filter device 130 from the filter device 130 and enter the dirt collecting device 150.

[0031] The automatic cleaning device 140 is provided with a linkage unit 142, and the linkage unit 142 has a first valve 1421 and a second valve 1422. The first valve 1421 is installed in the gap between the guide pipe 120 and the direction guide pipe 1141. The second valve 1422 is installed on the side wall of the guide pipe 120 near the first end face 111. The driving unit 141 has a turbine, which is arranged in a fluid channel formed by passing through the second valve 1422 from the first end face 111 to the second end face 112 when the second valve 1422 is opened. When the filtering device 100 performs filtering operation, the first valve 1421 is opened, and the fluid enters the filtering device 130 from the water inlet 1131 through the first valve 1421. When the filtering device 100 is performing a cleaning operation, the first valve 1421 is closed and the second valve 1422 is opened. At this time, the fluid enters the interior of the guide pipe 120 from the water inlet 1131 through the second valve 1422, and the turbine of the driving unit 141 is driven to rotate. The turbine drives the filter screen of the filtering device 130 to rotate to form sufficient centrifugal force, and debris such as mud and sand are discharged from the filtering device 130.

[0032] In one embodiment, Figure 4 As shown, the guide pipe 120 is not provided with an opening on the side facing the water outlet 1132; the linkage unit 142 includes a first valve 1421, a second valve 1422 and a third valve 1423, wherein the first valve 1421 is installed in the gap between the guide pipe 120 and the direction guide tube 1141, the second valve 1422 is installed on the side wall of the guide pipe 120 near the first end face 111, and the third valve 1423 is installed on the side wall of the guide pipe 120 near the second end face 112; the driving unit 141 includes a turbine, which is located in a fluid channel formed from the first end face through the second valve 1422 and the third valve 1423 to the second end face 112 when the first valve 1421 is closed and the second valve 1422 and the third valve 1423 are opened at the same time. The working principle of the turbine is as described above and will not be repeated here.

[0033] In yet another embodiment, Figure 5As shown, the linkage unit 142 includes a first valve 1421, a second valve 1422, a third valve 1423 and a fourth valve 1424, wherein the first valve 1421 is installed in the gap between the guide pipe 120 and the direction conduit 1141 near the first end face 111, the second valve 1422 is installed on the side wall of the guide pipe 120 near the first end face 111, the third valve 1423 is installed on the side wall of the guide pipe 120 near the second end face 112, and the fourth valve 1424 is installed in the gap between the guide pipe 120 and the direction conduit 1141 near the second end face 112; the driving unit 141 has a turbine, which is located in a fluid channel formed from the first end face through the second valve 1422 and the third valve 1423 to the second end face 112 when the first valve 1421 and the fourth valve 1424 are closed at the same time and the second valve 1422 and the third valve 1423 are opened at the same time. The working principle of the turbine is as described above and will not be repeated here.

[0034] In one embodiment, the driving unit 141 is an electric or mechanical driving device, such as an electric motor, or a driving mechanism including a diesel or gasoline engine, which directly drives the filter device 130 to rotate the filter device 130 to generate centrifugal force to make debris leave the filter device 130.

[0035] In one embodiment, the filter device 130 is provided with a gear or a gear transmission mechanism. When the filter device 100 performs filtering operation, the gear of the shaft on which the turbine is located is not meshed with the gear; when the filter device 100 performs cleaning operation, the gear of the shaft on which the turbine is located is meshed with the gear, the turbine drives the gear to rotate, and the gear drives the filter screen of the filter device 130 to rotate.

[0036] In one embodiment, the automatic cleaning device 140 further includes a vibration unit, which makes the filter device 130 vibrate when the driving device 141 is working.

[0037] The dirt collecting device 150 is connected to the housing 110 through the directional conduit 1141. In order to facilitate the discharge of dirt or replacement of the filter device 130, the dirt collecting device 150 and the housing 110 can be connected in a detachable manner, such as a threaded or snap-on connection.

[0038] The interior of the dirt collecting device 150 is hollow, and is used to receive the filtered impurities and accommodate the filter device 130. The interior of the dirt collecting device 150 is connected to the fluid channel 113 through the directional channel 1133 formed by the guide tube 120 and the directional conduit 1141. The fluid can flow into the dirt collecting device 150 from the water inlet 1131 through the directional channel 1133, and the fluid filtered by the filter device 130 flows into the fluid channel 113 from the opening of the guide tube 120, and finally flows out from the water outlet 1132.

[0039] Furthermore, in order to facilitate monitoring of the accumulation of impurities in the sewage collecting device 150, a sensing device may be provided in the sewage collecting device 150, so that when the impurities accumulate to a certain amount, it can be discovered in time, so that the impurities can be cleaned in time. Alternatively, the impurities in the sewage collecting device 150 may be cleaned regularly, so that there is no need to provide a sensing device, simplifying the structure of the fluid filtering device 100.

[0040] Additionally or alternatively, the sewage collecting device 150 may include a sewage discharge valve 151. Similarly, when impurities accumulate to a certain amount, the sewage discharge valve 151 can be simply opened to conveniently discharge the impurities contained therein without dismantling the entire sewage collecting device 150.

[0041] Each component of the utility model can be made of high temperature resistant material to adapt to different temperature conditions; at the same time, sealing rings can be provided at the connection of each component to prevent fluid leakage.

[0042] Reference Figure 3 According to the fluid flow direction shown in the figure, the working process of the fluid filtering device 100 is as follows: in the filtering state, the drain valve 151 is closed, the first valve 1421 is opened, and the second valve 1422 is closed. The fluid 160 flows in from the water inlet 1131, flows into the directional channel 1133 under the guidance of the outer wall of the guide pipe 120, and flows into the sewage collecting device 150 from the directional channel 1133 through the first valve 1421; the fluid in the sewage collecting device 150 flows into the filter element from the filter screen outside the filter device 130, passes through the filter element, and then flows out from the filter screen outside the filter element, flows into the fluid channel 113, and flows out of the filtering device 100 from the water outlet 1132.

[0043] In the cleaning state, the first valve 1421 is closed and the second valve 1422 is opened. The fluid drives the turbine to rotate from the water inlet 1131 through the second valve 1422, and the turbine drives the filter device 130 to rotate, generating centrifugal force to discharge impurities such as mud and sand from the filter device 130.

[0044] In the sewage discharge state, the water inlet 1131 of the filter device 100 is closed, the sewage discharge valve 151 is opened, and the impurities are discharged through the outlet of the sewage collecting device 150.

[0045] In summary, the utility model can automatically clean impurities and the like in the filtering device by arranging the automatic cleaning device in the filtering device, thereby improving the filtering effect of the filtering device and extending the service life of the filtering device.

[0046] Although the present invention is described above with reference to exemplary embodiments, the present invention is not limited thereto.
