Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people. During sewage treatment, the sewage needs to be discharged into the sewage treatment filter tank for preliminary filtration treatment before subsequent sewage treatment.

[0003] Sewage contains a large amount of organic matter, such as cellulose, starch, sugars, fats and proteins, etc. It also contains a large amount of sludge and various floating debris. When impurities are directly introduced into the sewage treatment filter tank along with sewage, it will affect the sewage treatment effect and increase the frequency of cleaning inside the equipment. When treating sewage, flocculants are usually added to the sewage to make the suspended solids settle to the bottom to form sludge. However, due to the light weight of the sludge, the sludge will move with the sewage during the long extraction process, which will lead to poor sewage treatment effect. Utility Model Content

At the top of the mounting frame 32, the inclined top end of the screening drum 6 is located inside the opening 101, the bottom of the water inlet pipe 31 is connected to the inside of the screening drum 6, a frame 61 is installed inside the screening drum 6, a second filter screen 62 is provided on the inner wall of the inclined bottom end of the screening drum 6, a spiral leaf 8 is provided inside the screening drum 6, the length of the spiral leaf 8 is the same as the length of the screening drum 6, one side of the spiral leaf 8 is fixedly connected to a mounting shaft 81, the other side of the mounting shaft 81 is fixedly connected to a pulley 2 82, one end of the surface of the mounting shaft 81 movably passes through the interior of the frame 61, the output shaft of the driving motor 7 is fixedly connected to a pulley 1 71, and the pulley 1 71 and the pulley 2 82 are connected by a belt.

[0025] In this embodiment, sewage is introduced into the screening drum 6 through the water inlet pipe 31. Since the screening drum 6 is in an inclined state, the sewage flows from top to bottom to the inclined bottom end of the screening drum 6, and the fixed impurities in the sewage are separated by the spiral blades 8. The sewage passes through the second filter screen 62 and flows into the filter tank 1. The drive motor 7 is started to drive the pulley 1 71 to rotate, and the pulley 1 71 is connected to the pulley 2 82 by a belt, so that the spiral blades 8 rotate with it. The rotation of the spiral blades 8 pushes the impurities inside the screening drum 6 out of the top of the screening drum 6, and then slides down from the opening 101 and falls into the sewage collecting box 2, so that the impurities in the sewage are separated and collected, and at the same time, the impurities can be prevented from clogging the second filter screen 62 and affecting the subsequent filtering effect.

[0026] Example 2

[0027] like Figure 1-Figure 5 As shown, a sewage pipe 13 and a drain pipe 14 are fixedly installed on the other side of the filter tank 1, a sleeve 4 is fixedly installed on the inner bottom end of the filter tank 1, a water pump 5 is fixedly installed on the top of the fixed block 12, the water pumping end of the water pump 5 is fixedly connected to one side of the drain pipe 14, the water outlet end of the water pump 5 is fixedly connected to a connecting pipe 51, the bottom end of the drain pipe 14 is located inside the sleeve 4, and a first filter screen 41 is fixedly installed on the surface of the sleeve 4.

[0028] In this embodiment, flocculant is added to sewage, and the sewage is allowed to stand for a period of time to separate and precipitate particles in the sewage. The height of the sleeve 4 should be replaced accordingly according to actual conditions. The volume of the filter tank determines the storage capacity of the sewage. The height of the sleeve 4 should be higher than the height of the sewage sediment to prevent the sediment from accumulating on the surface of the first filter screen 41 and clogging the sleeve 4. The sewage can be pumped out from the drain pipe 14 by starting the water pump 5, and the first filter screen 41 filters the sediment. Then, the sewage pipe 13 is opened to discharge the sediment in the filter tank to complete the treatment of the sewage.

[0029] The working principle of this embodiment is as follows: sewage is introduced into the screening drum 6 through the water inlet pipe 31, and the sewage flows from top to bottom to the inclined bottom end of the screening drum 6. The fixed impurities in the sewage are separated by the spiral blades 8, and the sewage passes through the second filter screen 62 and flows into the filter tank 1. The drive motor 7 is started to drive the pulley 1 71 to rotate, and the pulley 1 71 drives the pulley 2 82 and the spiral blades 8 to rotate. The spiral blades 8 rotate to push the impurities inside the screening drum 6 out of the top of the screening drum 6, and then slide down from the opening 101 and fall into the sewage collecting box 2, and the impurities in the sewage are separated and collected. Flocculant is added to the sewage, and it is left to stand for a period of time to separate and precipitate the particles in the sewage. The drain pipe 14 is located at the top of the sediment. The sewage can be pumped out from the drain pipe 14 by starting the water pump 5. The first filter screen 41 filters the sediment, and then the sewage pipe 13 is opened to discharge the sediment inside the filter tank, completing the treatment of the sewage.
