[0016] A method for using a building sewage treatment device is also provided, which is used to operate a building sewage treatment device, comprising the following steps: S1: The servo motor drives the water wheel to rotate, so that the sewage flows downward in a vortex state. The impurities such as silt in the water flow fall to the edge of the vortex, reducing the impact of silt and other impurities carried by the sewage on the filter screen, reducing the consumption of the filter frame, and at the same time guiding the collection downward in a spiral; S2: When the water flows downward in a spiral, the design of four sets of floating cylinders will drive four sets of cleaning brushes to clean the upper filter screen of the filter frame, and the cleaning cylinders will drive the needles to insert into the filter holes of the filter screen at the lower side of the filter frame for dredging; S3: After the filtering work is completed, the spherical rod and the L-shaped rod are lifted up by the elastic support of the spring, and the slip ring can be pushed by the L-shaped rod to bring several sets of dirt-pushing sheets to automatically discharge impurities or silt from the sewage pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The whole is connected to the sewage pipe. The sewage enters the interior of the shell through the water inlet pipe, fills the interior of the shell, is filtered from the filter frame, and then discharged outward through the drain pipe. During the working process, the servo motor drives the transmission rod and the water wheel to rotate rapidly, so that the internal sewage produces a vortex state and flows downward. At this time, the water flow in the vortex state, under the centrifugal force of rotation, throws the internal mud and other impurities to the edge of the vortex, and is stretched through the contraction. Under the centrifugal force of the water wheel on the water flow, the impurities have a certain time to approach the edge. After the spiral water flow passes through the contraction, the internal impurities will be thrown to the lower side of the shell, and the spiral moves downward. At this time, the filter net on the upper side of the filter frame can filter the center with less water flow, reduce the sewage carrying mud and other impurities to impact the filter net, and reduce the consumption of the filter frame. The mud or impurities moved to the edge will be guided downward by the spiral blade, and the spiral blade will transport the incoming impurities or mud downward, and the impurities that are not easily impacted by the incoming water flow will flow upward again, and finally flow to the sewage storage tank for collection.

[0018] When the water flows downward in a spiral, the design of the four groups of floats drives the four groups of floats to drive the four groups of support rods and rotating rods to rotate, so that the rotating sleeves on the outside drive the four groups of cleaning brushes to rotate along the connecting sleeves, and the four groups of cleaning brushes automatically clean the upper filter screen surface of the filter frame.

[0019] The rotating rod drives the cleaning rod, cleaning cylinder and L-shaped rod on the lower side to rotate, and the cleaning cylinder rolls against the inner wall of the filter frame. While the cleaning cylinder rolls, several groups of needles arranged on the surface are inserted into the filter holes of the filter mesh on the lower side of the filter frame for dredging, and the needles that are not effectively inserted into the filter holes will deform in conjunction with the elastic memory bulge to avoid affecting the rotation. In addition, when the four groups of floating cylinders rotate with the downward spiral water flow, the water flow will have downward thrust and suction, so that the rotating rod drives the L-shaped rod to slide downward, the arc sleeve and the spherical rod are separated, and the L-shaped rod and several groups of round rods are staggered in height to avoid driving the sewage discharge component to work during the filtration process.

[0020] After the filtration work is completed, under the elastic support of the spring, the spherical rod and the L-shaped rod are lifted up, the spherical rod is engaged with the arc sleeve, and the L-shaped rod is at the same height as the round rod. The servo motor can be used to drive the L-shaped rod to rotate, and the round rod is pushed to drive the slip ring to rotate along the movable port. At this time, the control valve is opened, and the rotating slip ring drives several groups of dirt pushing pieces to push the stored impurities or sediment in the sewage tank and automatically discharge them from the sewage pipe.

While the cleaning cylinder 515 rolls, several groups of needles 517 arranged on the surface are inserted into the filter holes of the filter screen on the lower side of the filter frame 51 for dredging, and the needles 517 that are not effectively inserted into the filter holes will cooperate with the elastic memory bulge 516 to deform to avoid affecting the rotation work. In addition, when the four groups of floating cylinders 511 rotate with the downward spiral water flow, the water flow will have a downward thrust and suction, so that the rotating rod 56 drives the L-shaped rod 518 to slide downward , the arc sleeve 45 is separated from the spherical rod 512, and the L-shaped rod 518 is staggered in height with several groups of round rods 69 to avoid driving the sewage discharge component 6 to work during the filtration process; finally, after the filtration work is completed, under the elastic support of the spring 59, the spherical rod 512 and the L-shaped rod 518 are lifted up, the spherical rod 512 is engaged with the arc sleeve 45, and the L-shaped rod 518 is at the same height as the round rod 69, so that the L-shaped rod 518 can be driven to rotate by the servo motor 41, and the round rod 69 is pushed to drive the slip ring 66 to rotate along the movable port 65, and the control valve 611 is opened at this time, and the rotating slip ring 66 drives several groups of sewage pushing pieces 68 to push the stored impurities or silt in the sewage storage tank 63, and automatically discharge them outward from the sewage discharge pipe 610.
