[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figures 1-4 shown, a sewage treatment and purification device includes a box body 1. A treatment tank 2 is provided inside the box body 1. A sewage inlet 12 communicating with the treatment tank 2 is provided on one side of the top of the box body 1. An arc-shaped filter plate 3 is fixed inside the treatment tank 2. One side of the arc-shaped filter plate 3 extends to the outside of the treatment tank 2. A cleaning mechanism for cleaning the arc-shaped filter plate 3 is provided inside the treatment tank 2. A power mechanism for driving the cleaning mechanism to work is provided inside the box body 1 and below the arc-shaped filter plate 3.

[0024] The cleaning mechanism includes a screw conveyor 4 rotatably installed on one side inside the treatment tank 2. The outer wall of the screw conveyor 4 contacts the arc-shaped filter plate 3. One end of the screw conveyor 4 extends to the outside of the box body 1 and is connected with a universal coupling 9. An L-shaped mounting plate 10 is fixed on one side of the box body 1. A second rotating shaft 11 is rotatably installed through one side of the L-shaped mounting plate 10. One end of the second rotating shaft 11 is connected with the universal coupling 9. A collection box 16 is provided on one side of the box body 1 and below the discharge port of the arc-shaped filter plate 3. By rotating the screw conveyor 4, the impurities on the arc-shaped filter plate 3 can be pushed towards the discharge port side, so that the impurities finally enter the collection box 16 along the arc-shaped filter plate 3. The operation is simple, which is convenient for cleaning the arc-shaped filter plate 3 and preventing the arc-shaped filter plate 3 from being blocked by impurities and affecting the sewage treatment effect.

[0025] The power mechanism includes a through groove 5 opened at the inner bottom of the treatment tank 2. A collection tank 14 communicating with the through groove 5 is opened inside the box body 1. An installation groove 6 is opened on one side inside the through groove 5. A first rotating shaft 7 is rotatably installed through the installation groove 6. Water wheel blades 8 are arranged on the outer wall of the first rotating shaft 7. One-half of the whole water wheel blades 8 is located inside the through groove 5, so that the water flowing through the through groove 5 can smoothly fall on one side of the water wheel blades 8, which is convenient for the water wheel blades 8 to rotate smoothly in one direction. The other end of the first rotating shaft 7 penetrates through the outer wall of the L-shaped mounting plate 10. The first rotating shaft 7 and the second rotating shaft 11 are connected to each other by a belt.

[0026] One end of the first rotating shaft 7 and the second rotating shaft 11 is provided with a synchronous pulley, and a synchronous belt is arranged between the outer walls of the two synchronous pulleys. When the sewage treated by the arc-shaped filter plate 3 and the activated carbon purification plate 17 falls along the through groove 5, it falls back onto the blades of the water wheel blade 8. Under the impact of the water flow, the water wheel blade 8 rotates. The water wheel blade 8 drives the first rotating shaft 7 to rotate, and the first rotating shaft 7 drives the second rotating shaft 11 to rotate through the cooperation of the synchronous belt and the synchronous pulley. The second rotating shaft 11 cooperates with the universal coupling 9 to drive the auger 4. By the flow of water driving the water wheel blade 8 to rotate, without the intervention of other power sources, the use of the equipment is relatively energy-saving and environmentally friendly.

[0027] As Figures 1-3 shown, the arc-shaped filter plate 3 and the auger 4 are inclined and installed in the treatment tank 2, and the inclination angle is twenty degrees, so that the arc-shaped filter plate 3 has a certain slope, enabling the sewage to smoothly pass through the arc-shaped filter plate 3 and preventing the leakage of sewage.

[0028] As Figures 2-3 shown, a detachable activated carbon purification plate 17 is provided on the outer wall of the box body 1 and located below the arc-shaped filter plate 3. The set activated carbon purification plate 17 can further treat and purify the sewage, improving the effect of sewage treatment.

[0029] As Figure 1 shown, a drain pipe 15 communicating with the collection tank 14 is provided on one side of the box body 1, and a valve is arranged on the outer wall of the drain pipe 15. The set drain pipe 15 facilitates the discharge of the purified sewage.

[0030] As Figures 2-3 shown, one side of the arc-shaped filter plate 3 extends to the outside of the box body 1 and is rotatably installed with a pressing cover 13. Installation ears are arranged on both sides of the pressing cover 13, and the installation ears are rotatably connected to both sides of the arc-shaped filter plate 3 through the third rotating shaft. A torsion spring is arranged at the rotating connection of the pressing cover 13 and the arc-shaped filter plate 3. The torsion spring is sleeved on the third rotating shaft and its two ends are respectively fixed to the outer wall of the arc-shaped filter plate 3 and the installation ear. When the auger 4 cleans the impurities on the arc-shaped filter plate 3, the auger 4 pushes the impurities on the arc-shaped filter plate 3 to move to one side. During the movement, in cooperation with the pressing cover 13 and the torsion spring, the impurities are squeezed, so that the water in the impurities is squeezed out, preventing it from entering the collection tank 14 together with the impurities.

[0031] The working principle of the utility model is as follows: When in use, sewage enters the treatment tank 2 from the sewage inlet 12. After being filtered by the arc-shaped filter plate 3, the impurities in the sewage are blocked on the surface of the arc-shaped filter plate 3. The sewage is then secondarily filtered by the activated carbon purification plate 17, improving the sewage treatment effect. The sewage passing through the activated carbon purification plate 17 flows through the through groove 5 into the collection tank 14, and finally is discharged through the drain pipe 15. When the sewage flows through the through groove 5, the water flow impacts one side of the water wheel blade 8 and causes the water wheel blade 8 to rotate. The water wheel blade 8 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the second rotating shaft 11 to rotate through the cooperation of the synchronous belt and the synchronous pulley. The second rotating shaft 11 drives the auger 4 to rotate through the universal coupling 9. When the auger 4 rotates, it pushes the impurities on the surface of the arc-shaped filter plate 3 to one side. In cooperation with the pressing cover 13 and the torsion spring, when the impurities come into contact with the pressing cover 13, the impurities are squeezed, and the excess water in the impurities is squeezed out, preventing the sewage from being carried away by the impurities. The pushing force of the auger 4 pushing the impurities is greater than the torsion force of the torsion spring, and finally the impurities smoothly enter the collection box 16.

[0032] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices, and operation methods not specifically described and explained in the utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
