However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a municipal sewage filtering device, comprising: a filter frame 1, a slide groove 22 is symmetrically opened on the top of the filter frame 1, and the inner surfaces of the slide grooves 22 are slidably connected with mounting frames 7, and the inner surfaces of the two mounting frames 7 are sequentially provided with filter screens 14 and activated carbon filter elements 15, a motor 5 is fixedly connected to the top of the filter frame 1, and the output end of the motor 5 is movably penetrated with the top of the filter frame 1, and the output end of the motor 5 is fixedly connected with a threaded rod 11, and the outer surface of the threaded rod 11 is threadedly connected with a brush 12, a collecting bucket 2 is fixedly connected to the bottom of the filter frame 1, and a sealing cover 3 is threadedly connected to the bottom of the collecting bucket 2, the outer surface of the brush 12 is fitted with the outer surface of the filter screen 14, and the position of the filter screen 14 matches the position of the collecting bucket 2, a sliding rod 13 is fixedly connected to the inner surface of the filter frame 1, and the sliding rod 13 and the brush 12 are movably penetrated, and the outer surfaces of the two mounting frames 7 are provided with rubber strips 21, the top of the filter frame 1 is fixedly connected with a water inlet pipe 4, and the outer surface of one side of the filter frame 1 is fixedly connected with a water outlet pipe 6.

[0023] The effect achieved by the entire embodiment 1 is that when the sewage enters the filter frame 1 through the water inlet pipe 4, the particles and impurities in the sewage are filtered with the cooperation of the filter screen 14, and then the filtered sewage passes through the activated carbon filter element 15 to adsorb organic matter, heavy metals, certain soluble inorganic substances and chlorine in the sewage, and the sewage is double-filtered to ensure the purification effect of the sewage, and then the filtered sewage is discharged from the filter frame 1 through the outlet pipe 6. After long-term use, the motor 5 can be started to drive the threaded rod 11 to enter the filter frame 1. The brush 12 is rotated, and with the cooperation of the sliding rod 13, the brush 12 slides up and down along the threaded rod 11 and the sliding rod 13, thereby driving the brush 12 to move up and down. Therefore, the impurities attached to the filter screen 14 can be brushed off by the brush 12 to avoid the impurities clogging the filter holes on the filter screen 14, thereby ensuring the filtering effect of the filter screen 14 on the sewage, and then the impurities brushed off will be collected in the collecting bucket 2, and then the sealing cover 3 can be unscrewed to remove the impurities in the collecting bucket 2 to avoid the accumulation of impurities in the filter frame 1.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the top of the filter frame 1 is fixedly connected to a rotating rod 10 near the two slide grooves 22, and the outer surfaces of the two rotating rods 10 are rotatably connected to the limiting rod 8. The top of the filter frame 1 is fixedly connected to two clamping blocks 9, and the inner surfaces of the two clamping blocks 9 are respectively matched with the outer surfaces of the two limiting rods 8. The tops of the two clamping blocks 9 are movably connected through the limited blocks 18, and the tops of the two limiting blocks 18 are fixedly connected with the pressing blocks 20. The outer surfaces of the two limiting blocks 18 are sleeved with springs 19, one ends of the two springs 19 are respectively fixedly connected to the bottoms of the two pressing blocks 20, and the other ends of the two springs 19 are respectively fixedly connected to the tops of the two clamping blocks 9, and the tops of the two clamping blocks 9 are fixedly connected with telescopic rods 17, and the tops of the two telescopic rods 17 are respectively fixedly connected to the bottoms of the two pressing blocks 20, and the two limiting blocks 18 are respectively matched with the two limiting rods 8.

[0025] The effect achieved by the entire embodiment 2 is that when the filter screen 14 or the activated carbon filter element 15 needs to be replaced, the valve on the water inlet pipe 4 is closed, and the pressure block 20 is pulled upward to move the limit block 18 upward, and the spring 19 is stretched. Under the action of the telescopic rod 17, the movement spacing of the limit block 18 is limited, and then the limit rod 8 is moved to rotate the limit rod 8 along the axis of the rotating rod 10, so that the limit rod 8 is disengaged from the block 9, and then the mounting frame 7 can be pulled out of the slide groove 22 through the handle groove on the mounting frame 7, so that the filter screen 14 or the activated carbon filter element 15 can be replaced conveniently. The filter frame 1 can be replaced, but when it needs to be installed, after the mounting frame 7 is inserted into the filter frame 1 along the slide groove 22, the pressure block 20 is pulled upward again to move the limit block 18 upward and stretch the spring 19, and then the limit rod 8 is rotated to move the limit rod 8 to the inner wall of the block 9, and then the pressure block 20 is released. Under the rebound force of the spring 19, the pressure block 20 and the limit block 18 will be driven to move downward, and the limit rod 8 will be limited and fixed inside the block 9 by the limit block 18, thereby completing the installation of the mounting frame 7, and the sealing of the mounting frame 7 and the slide groove 22 during installation is guaranteed under the action of the rubber strip 21.

[0026] Working principle: When the sewage enters the filter frame 1 through the water inlet pipe 4, the particulate matter and impurities in the sewage will be filtered with the cooperation of the filter net 14, and then the filtered sewage will pass through the activated carbon filter element 15 to adsorb organic matter, heavy metals, certain soluble inorganic substances and chlorine in the sewage, and double filter the sewage to ensure the purification effect of the sewage, and then the filtered sewage is discharged from the filter frame 1 through the outlet pipe 6. After long-term use, the motor 5 can be started to drive the threaded rod 11 to rotate in the filter frame 1, and with the cooperation of the sliding rod 13, the brush 12 can slide up and down along the threaded rod 11 and the sliding rod 13, thereby driving the brush 12 to move up and down. Therefore, under the action of the brush 12, the impurities attached to the filter net 14 can be brushed off to prevent the impurities from clogging the filter net 1 4, ensure the filtering effect of the filter screen 14 on the sewage, and then the impurities brushed behind will be collected in the collecting bucket 2, and then the impurities in the collecting bucket 2 can be removed by unscrewing the sealing cover 3 to avoid the accumulation of impurities in the filter frame 1. When the filter screen 14 or the activated carbon filter element 15 needs to be replaced, the valve on the water inlet pipe 4 is closed, and the pressure block 20 is pulled upward to move the limit block 18 upward, and the spring 19 is stretched. Under the action of the telescopic rod 17, the moving spacing of the limit block 18 is limited, and then the limit rod 8 is toggled to make the limit rod 8 rotate along the axis of the rotating rod 10, so that the limit rod 8 is disengaged from the block 9, and then the mounting frame 7 can be drawn out from the slide groove 22 through the handle groove on the mounting frame 7, so as to facilitate the replacement of the filter screen 14 or the activated carbon filter element 15.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
