A water filter port 6 that can communicate with the collection chamber 3 and the filter chamber 4 is provided on the partition 5, and a valve 7 is provided at the water filter port 6. A filter screen plate 8 is provided on one side of the partition 5 close to the collection chamber 3. The filter screen plate 8 extends upward to the top of the partition 5 and extends downward to the bottom of the partition 5, and can cover the entire water filter port 6; a first top cover 9 that can be opened is provided on the top of the collection chamber 3, and a plurality of valves that are connected to the collection chamber 3 are provided on the first top cover 9. A water leakage hole 10 is connected to the inside of the cavity 3, and a stirring mechanism is provided inside the collecting cavity 3; a PP cotton layer 11 and an activated carbon layer 12 are provided in sequence inside the filtering cavity 4, and the planes where the PP cotton layer 11 and the activated carbon layer 12 are located are parallel to the plane where the partition 5 is located, and the PP cotton layer 11 and the activated carbon layer 12 are both arranged using the existing technology; a drain outlet is provided at the bottom of the filtering cavity 4 away from the collecting cavity 3, and a drain pipe 13 is fixed at the drain outlet, and the end of the drain pipe 13 away from the drain outlet is located above the storage box 2 and leads to the interior of the storage box 2.

[0022] When the utility model is actually used, a deep groove can be dug downward on the ground, and the recovery box 1 and the storage box 2 can be placed in the deep groove, and the first top cover 9 of the collection chamber 3 can be made flush with the ground. Then, the electric cleaning equipment or other cleaning equipment in the prior art can be set above the first top cover 9. When in use, the vehicle can be driven to the first top cover 9 above the collection chamber 3, and then the cleaning can be carried out. It is worth noting that the storage box 2 should be lower than the recovery box 1 to prevent the filtered water in the filter chamber 4 from flowing into the recovery box 1. In addition, the device can also be placed on the ground, and a platform 30 can be set on the side of the recovery box 1 away from the storage box 2, such as Figure 1 As shown, the platform 30 can facilitate vehicles to drive onto the first top cover 9 above the collection chamber 3.

[0023] When the utility model is used in practice, the vehicle is first driven to the first top cover 9 above the collection chamber 3, and then the vehicle is washed using a car wash device. The waste water generated by washing flows into the collection chamber 3 along the water leakage holes 10 on the first top cover 9, thereby collecting the waste water. The water leakage holes 10 are arranged on both sides of the first top cover 9. To facilitate the waste water to flow into the water leakage holes 10, the middle of the first top cover 9 can be slightly higher than the two sides during production, so that the waste water can flow to the two sides of the first top cover 9. Then, after collecting waste water for a period of time, a flocculant or other agent can be added from the water leakage holes 10 to the collection chamber 3, so that the dirt in the water is gathered and precipitated, and then as Figure 5As shown, open the valve 7 on the partition 5, the wastewater passes through the filter screen 8, and the filter screen 8 initially filters out most of the impurities in the wastewater, and then flows into the filter chamber 4, and passes through the PP cotton layer 11 and the activated carbon layer 12 in the filter chamber 4 in sequence. When the wastewater passes through the PP cotton layer 11, the wastewater will be filtered twice, and the wastewater can be filtered more carefully. When the wastewater passes through the activated carbon layer 12, the wastewater will be filtered three times. The activated carbon layer 12 can absorb harmful substances in the wastewater and eliminate the odor in the wastewater, thereby obtaining purified water, and finally flows into the storage box 2 through the drain port and the drain pipe 13. The purified water can continue to be used for vehicle washing or other purposes; wherein a control valve can also be set at the drain port to control the switch of the drain port. Through the above operation, the utility model can make the wastewater be reused again, and at the same time protect the environment and groundwater resources in the soil.

When the filter screen plate 8 needs to be cleaned or replaced, the filter screen plate 8 can be pulled upward, the filter screen plate 8 can be removed for cleaning, or directly replaced with a new one.

[0025] like Figure 1 and Figure 3 As shown, one side of the first top cover 9 is connected to the outer wall corresponding to the collecting chamber 3 by a hinge, and a cylinder 14 is provided on the other opposite outer wall of the collecting chamber 3, and a cylinder fixing seat 15 is also provided on the outer wall. The bottom end of the cylinder 14 is rotatably connected to the cylinder fixing seat 15, and its piston rod end is rotatably connected to the corresponding end of the first top cover 9, wherein a connector (not shown in the figure) can be provided at a corresponding position on one side of the first top cover 9 close to the cylinder 14, and then the piston rod of the cylinder 14 is rotatably connected to the connector. When in use, the cylinder 14 is used to push one end of the first top cover 9 so that the first top cover 9 is as shown in FIG. Figure 3The utility model opens the first top cover 9 as shown. The way in which the cylinder 14 pushes the first top cover 9 to open and the connection with the cylinder 14 are all based on the existing technology and will not be described in detail here. At regular intervals, the first top cover 9 can be opened to manually clean the collection chamber 3. In addition, the utility model can also set a second top cover 16 on the top of the filter chamber 4 and a third top cover 17 on the top of the storage box 2. The second top cover 16 and the third top cover 17 are set in the same way as the first top cover 9, which is convenient for opening the second top cover 16 or the third top cover 17 and regularly cleaning the filter chamber 4 or the storage box 2. A water outlet (not shown in the figure) can also be set on the third top cover 17 of the storage box 2 to facilitate taking water from the storage box 2.

[0026] The utility model Figure 2-Figure 4As shown, a stirring mechanism is also provided in the collection chamber 3 for stirring the wastewater after the flocculant is placed. The stirring mechanism includes a gear plate 20 and a turntable 21; a plurality of connecting rods 22 are fixedly provided on the upper surface of the gear plate 20, and the plurality of connecting rods 22 are evenly arranged along the circumferential direction of the gear plate 20, and the upper ends of the plurality of connecting rods 22 are fixedly connected to the bottom surface of the first top cover 9; a stepper motor 23 is provided above the gear plate 20; a rotating shaft 24 is fixedly provided at the center of the turntable 21, the turntable 21 is located below the gear plate 20, the top end of the rotating shaft 24 passes through the center of the gear plate 20 and is rotatably connected thereto, and the motor shaft of the stepper motor 23 is fixedly connected to the top end of the rotating shaft 24; a plurality of stirring rods 26 are provided at the bottom of the turntable 21, and the stirring rods 26 are arranged along the circumferential direction of the turntable 21, and stirring blades 27 are provided on the stirring rods 26. After the flocculant is added to the wastewater, the stirring mechanism can be turned on. The stirring mechanism can drive the rotating shaft 24 to rotate through the stepping motor 23. The rotating shaft 24 and the turntable 21 are integrally formed, so the turntable 21 rotates with the rotating shaft 24, and the turntable 21 is provided with a plurality of stirring rods 26, and the stirring rods 26 can rotate with the turntable 21, so as to stir the wastewater. The coordinated setting of the turntable 21 and the plurality of stirring rods 26 expands the stirring area, increases the stirring speed, can speed up the mixing of the wastewater and the flocculant, and speeds up the flocculation and sedimentation speed.

When the turntable 21 rotates, the stirring rod 26 rotates accordingly, and drives the gear 28 to rotate around the central axis of the turntable 21 along with the stirring rod 26. During the rotation process, the gear 28 is meshed with the gear plate 20, and the gear plate 20 is fixed at the bottom of the top cover and rotatably connected with the rotating shaft 24, and itself is fixed. Therefore, when the gear 28 is meshed with the gear plate 20, the gear plate 20 will cause the gear 28 to rotate on its own, thereby driving the stirring rod 26 to rotate on its own, so that the stirring rod 26 rotates on its own while revolving with the turntable 21, further improving the stirring efficiency, accelerating the mixing of the wastewater and the flocculant, and allowing the two to fully react, so that the dirt in the water is fully flocculated and precipitated, shortening the reaction and precipitation time, and improving the precipitation efficiency. At the same time, it is ensured that the impurities in the wastewater are cleanly adsorbed by the flocculant, ensuring the purification degree of the wastewater, and further avoiding the filtered clean water from polluting the environment in subsequent use.

[0027] In addition, Figure 3As shown, the outer cover of the turntable 21 is provided with an annular protective cover 29, the upper end of the protective cover 29 extends to the bottom of the first top cover 9, and is fixedly connected to the bottom of the first top cover 9, and the lower end of the protective cover 29 extends to the lower end of the turntable 21. The protective cover 29 and the turntable 21 form a cavity, which covers the stepper motor 23, the gear 28, and the gear plate 20, and plays a certain protective role. In addition, the outer surfaces of the protective cover 29, the turntable 21 and the stepper motor 23 are all waterproofed to extend their service life. At the same time, the water leakage eye 10 is arranged on both sides of the first top cover 9, and is located outside the circumference of the protective cover 29, that is, the water leakage eye 10 is not connected to the inside of the protective cover 29, so as to prevent waste water from entering the protective cover 29 from the water leakage eye 10 and damaging the components in the protective cover 29 such as the stepper motor 23.
