[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage generated in daily life contains a lot of solid waste, which usually needs to be filtered and separated using a filter barrel. However, when separating sewage, the existing filter barrel only passes through a layer of filtering device. Under the impact of sewage, the sewage will impact the solid waste into the filter net, causing the sewage and solid waste to mix together. The filtering effect is poor, and the solid waste is easy to cause the filter net to be blocked. The treatment process is complicated, the cost is high, and the treatment time is long, the efficiency is low, and it does not meet the needs. Summary of the invention

[0006] The present invention is also characterized in that: The discharge pipe includes an upper panel, which is fixedly connected to the discharge port, and the lower center of the upper panel is vertically connected to a fixed shaft. A plurality of spherical protrusions are radially arranged on the outer surface of the fixed shaft. A rotating block is sleeved on the fixed shaft, and a plurality of grooves are radially arranged on the inner surface of the rotating block, and the spherical protrusions are adapted to the grooves. Two groups of circular notches are arranged through the relative position of the rotating block and the upper panel of the discharge pipe, and the circular notches on the upper panel of the discharge pipe and the surface of the rotating block are the same in size.

[0007] The filtering mechanism includes a fixed frame, which is arranged in the cavity of the reaction chamber. The upper surface of the fixed frame is inclined. Several rotating shafts are arranged in sequence on the upper surface of the fixed frame. Each rotating shaft is rotatably sleeved on a supporting cross plate. A torque spring is arranged on the other end of the supporting cross plate opposite to the rotating shaft. The supporting cross plate is horizontally fixed and connected to the fixed frame through the torque spring. Several filter screens are arranged on the upper surface of each cross plate and the inclined upper surface of the fixed frame.

[0008] A filter outlet is arranged below one side of the lowest end supporting horizontal plate, and a telescopic rod is arranged above the highest end supporting horizontal plate on the opposite side. The extending direction of the telescopic rod is perpendicular to the axis of the rotating shaft, and the end of the telescopic rod is rotatably connected to the auxiliary plate. The angle between the auxiliary plate and the telescopic rod is an acute angle, and the inclination direction of the auxiliary plate is opposite to the top of the feed block.

[0011] Another technical solution adopted by the present invention is a method for using a filter barrel for treating domestic sewage, which is specifically implemented according to the following steps: directly pouring sewage through the inclined surface at the top of the feed block, the sewage impacts the auxiliary plate, the impacting water exerts an impact force on the auxiliary plate, the auxiliary plate pushes the telescopic rod to shrink, the sewage falls along the auxiliary plate to the horizontal plate, the sewage impacts the horizontal plate, the horizontal plate is forced to rotate, the solid waste inside the sewage will be blocked by the rubber strip on the surface of the horizontal plate, so that the sewage will pass through the filter screen on the surface of the horizontal plate and the filter screen on the surface of the fixed frame, and fall into the discharge pipe; when the solid waste is accumulated, the horizontal plate is pressed to rotate, the torque spring causes the horizontal plate to tilt, and then the solid waste falls to the filter outlet, and finally the solid waste falls into the discharge pipe; finally, manually rotate the rotating block, when the circular notch on the surface of the rotating block coincides with the circular notch on the surface of the discharge pipe, the sewage and solid waste will pass through the discharge pipe and the rotating block and flow out.
