DETAILED DESCRIPTION

[0017] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0018] A sewage filtering device with automatic cleaning function, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a filter bin 2, a water inlet pipe 3, a cover 7, a motor 10, a filter cover 11, a tray 12 and a spiral brush 13. The top of the bracket 1 is fixedly connected to the filter bin 2, the top of the filter bin 2 is open, the inside of the filter bin 2 is slidably connected to the filter cover 11, the top of the filter bin 2 is slidably connected to the cover 7, the top of the cover 7 is installed with a motor 10, the output shaft of the motor 10 is fixedly connected to the spiral brush 13, the bottom of the spiral brush 13 is rotatably connected to the tray 12, the tray 12 is slidably connected to the filter cover 11, the spiral brush 13 and the tray 12 are both located inside the filter cover 11, the upper front side of the filter bin 2 is fixedly connected to the water inlet pipe 3, the water inlet pipe 3 passes through the filter bin 2 and the filter cover 11, and a water outlet is opened at the bottom of the rear side of the filter bin 2. When it is necessary to use the device to filter sewage, the sewage is discharged into the filter cover 11 through the water inlet pipe 3. After the sewage enters the filter cover 11, the impurities will be isolated in the filter cover 11 by the holes on the filter cover 11, and the impurities will fall on the tray 12. After the device is used for a period of time, the impurities will block the holes on the filter cover 11, and the filter cover 11 needs to be cleaned. The motor 10 is started to rotate the spiral brush 13, and the impurities on the filter cover 11 are scraped off by the spiral brush 13, and the impurities fall on the tray 12 again, and the treated sewage flows out from the holes in the filter cover 11, and finally the treated sewage is discharged from the drain port. The rotation of the spiral brush 13 can brush off the impurities adhered to the filter cover 11. Only the motor 10 needs to be started to clean the filter cover 11, so as to prevent the impurities from clogging the filter cover 11 and causing the filtering effect of the device to be reduced, and to avoid the filter cover 11 from being damaged, thereby increasing the service life of the device.

[0019] like Figure 1-Figure 3As shown, it also includes an electric push rod 8 and a connecting rod 9. The electric push rod 8 is installed on the right side of the filter chamber 2. The push rod of the electric push rod 8 is fixedly connected with the connecting rod 9, and the other end of the connecting rod 9 is fixedly connected to the top of the cover 7. When a lot of impurities are accumulated on the tray 12, it is necessary to clean the impurities on the tray 12, stop discharging sewage into the filter chamber 2, start the electric push rod 8 to drive the cover 7 to move upward through the connecting rod 9, so as to lift the cover 7, the motor 10, the spiral brush 13 and the tray 12 upward, when the tray 12 leaves the filter chamber 2, the impurities on the tray 12 and the spiral brush 13 are cleaned, and then the electric push rod 8 drives the cover 7 to move downward through the connecting rod 9, so as to move the cover 7, the motor 10, the spiral brush 13 and the tray 12 downward, when the tray 12 is reset, the sewage is discharged into the filter chamber 2 for sewage filtering operation, the tray 12 can be removed by the electric push rod 8, and then the impurities on the tray 12 are cleaned, so as to prevent the impurities from accumulating too much on the tray 12 and causing the filtration efficiency to decrease.

[0020] like Figure 1 and Figure 2 As shown, it also includes a sewage hopper 4, which is fixedly connected to the upper part of the filter chamber 2, and the sewage hopper 4 is open on the left side. When cleaning impurities on the tray 12, the electric push rod 8 is started to move the tray 12 upward and away from the filter chamber 2, and the impurities on the tray 12 will fall into the sewage hopper 4, and the impurities will be discharged from the device through the opening of the sewage hopper 4. The sewage hopper 4 can collect the impurities on the tray 12 when cleaning the tray 12, preventing the impurities from falling on the surface of the device when cleaning the tray 12 and causing pollution, so that the device can be kept clean and tidy.

[0021] like Figure 2 As shown, it also includes a shielding plate 6 and a filter plate, at least one filter plate is installed at the water outlet, a through hole is opened at the rear side of the top of the bracket 1, the through hole is communicated with the top of the water outlet, and the shielding plate 6 is rotatably connected to the through hole at the top of the bracket 1. After the sewage is initially filtered by the filter cover 11, the sewage will flow to the water outlet and pass through the filter plate for a second filtration, and the sewage filtered for the second time will be discharged from the water outlet. When the filter plate is used for a period of time, impurities will adhere to the filter plate. At this time, the filter plate needs to be cleaned. After opening the shielding plate 6, the filter plate is taken out for cleaning. After the filter plate is cleaned, the filter plate is put into the water outlet, and finally the shielding plate 6 is closed. While the sewage is filtered for the second time, the filter plate can also be disassembled and cleaned, thereby improving the filtering efficiency of the device.

[0022] like Figure 2As shown, a Y-type filter 5 is also included, and a Y-type filter 5 is installed at the rear side of the water outlet. After the sewage is filtered twice, it is filtered for the third time through the Y-type filter 5 when it flows out of the water outlet. The sewage is filtered by the Y-type filter 5 and then discharged from the device, so that the sewage discharged from the device is cleaner. When a certain amount of impurities accumulate in the Y-type filter 5, the Y-type filter 5 needs to be cleaned. At this time, the sewage is stopped from being discharged into the filter bin 2. The cleaning operation can be performed by simply removing the flange cover on the Y-type filter 5. After the Y-type filter 5 is cleaned, the flange cover is installed back on the Y-type filter 5, and the sewage is discharged into the filter bin 2 again for filtering. The Y-type filter 5 can achieve three filtrations of the sewage, and the Y-type filter 5 can also be cleaned of impurities by removing the flange cover of the Y-type filter 5, further improving the filtering efficiency of the device.

[0023] like Figure 1 As shown, an adjustable valve 31 is also included, and the front side of the water inlet pipe 3 is fixedly connected with the adjustable valve 31. After using the device to filter sewage for a period of time, impurities will remain in the filter cover 11, the filter plate and the Y-type filter 5, and the filter cover 11, the filter plate and the Y-type filter 5 need to be cleaned. By controlling the adjustable valve 31 to stop the sewage from being discharged into the filter chamber 2, it is convenient to clean the impurities in the filtering device and prevent the sewage from interfering with the cleaning of the filter cover 11, the filter plate and the Y-type filter 5. The flow rate of the sewage discharged can also be controlled by adjusting the adjustable valve 31 to prevent the sewage flow rate from being too large, thereby reducing the filtering efficiency of the device, ensuring the normal operation of the device and improving the service life of the device.
