Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 1, the municipal wastewater recycling device provided by this embodiment includes a recycling tank 1, a partition board 2 is vertically disposed in the recycling tank 1, the partition board 2 divides the recycling tank 1 into a right inlet tank 3 and a left filter tank 4, the depth of the right inlet tank 3 is smaller than that of the left filter tank 4, by this arrangement, the sedimentation effect in the left filter tank 4 can be greatly increased, specifically as shown in fig. 3 and 4, the position of the third inlet channel 9 in fig. 4 is higher than that of the third inlet channel 9 in fig. 3, the third inlet channel 9 will be specifically explained below, the position of the third inlet channel 9 in fig. 3 is lower, the liftable height of the water flow is higher than that of the water flow in fig. 4, the pollutants can sink in the ascending process, however, the pollutants that have fallen to the bottom of the left filter tank 4 are brought into the upper part with the water flow due to the influence of the inlet water in fig. 3, secondary scouring is formed, which is extremely disadvantageous to the accumulation of pollutants. In a reverse view of fig. 4, since the position of the third water inlet channel 9 is higher, the vortex position caused by the water flow changes, and the vortex position moves downward, although the vortex also generates a certain disturbance to the settled pollutants, compared with fig. 3, the vortex with a lower flow rate has a smaller influence on the overall settling effect, so that the settling effect of the pollutants is greatly improved, and therefore, the depth of the right water inlet tank 3 is set to be smaller than that of the left filter tank 4.

As shown in fig. 1, a first energy dissipation plate 5 and a second energy dissipation plate 6 are vertically arranged in the right inlet tank 3 from right to left in sequence, the first energy dissipation plate 5 is connected with the top of the right inlet tank 3, a first water inlet channel 7 is arranged between the bottom of the first energy dissipation plate 5 and the bottom of the right inlet tank 3, the second energy dissipation plate 6 is connected with the bottom of the right inlet tank 3, a second water inlet channel 8 is arranged between the top of the second energy dissipation plate 6 and the top of the right inlet tank 3, the top of the isolation plate 2 is connected with the top of the right inlet tank 3, a third water inlet channel 9 communicating the right inlet tank and the left filter tank is arranged between the bottom of the isolation plate 2 and the bottom of the right inlet tank 3, in order to further make the flow rate of sewage entering the left filter tank 4 through the third water inlet channel 9 more uniform, a water distribution plate 17 which is matched with the third water inlet channel 9 can be vertically arranged in the third water inlet channel 9, and the water distribution plate 17 is integrally formed with the isolation plate 2, the water distribution plate 17 is provided with a plurality of water distribution holes 18, as shown in fig. 2, the aperture of the water distribution holes 18 around the water distribution plate is larger than the aperture of the water distribution holes 18 in the middle of the water distribution plate, and the middle holes are small in area and large in area around the water distribution plate, so that water flow can be automatically dispersed around the water distribution plate, the water distribution is uniform, the flow speed of sewage in the left filter tank 4 is directly reduced, the precipitation effect of magazines in the left filter tank 4 is improved, and the water distribution plate is only an optimal mode.

The right side wall of the right water inlet tank 3 relative to the first energy dissipation plate 5 is provided with a water inlet 10, the left side wall of the left filtering tank 4 relative to the isolation plate is provided with a water outlet 11, the bottom of the right water inlet tank on the right side of the second energy dissipation plate 6 is provided with a first sludge discharge port 12, and the bottom of the left filtering tank 4 is provided with a second sludge discharge port 13. In order to facilitate the second sludge discharge port 13 to discharge sludge, the bottom of the left filtering tank 4 may be configured as a funnel shape, and the second sludge discharge port 13 is disposed at the lowest position of the bottom of the left filtering tank 4.

The specific sewage flow direction is as follows: enters the right water inlet tank 3 from the water inlet 10, then dissipates energy through the first energy dissipation plate 5, passes through the first water inlet channel 7, passes through the second energy dissipation plate 6, flows to the third water inlet channel 9 through the second water inlet channel 8, enters the left filtering tank 4 for precipitation and filtration, and finally filtered sewage is reserved from the water outlet 11. The device overall structure is simple, when carrying out preliminary filtration treatment to urban wastewater, can filter the great polluted particles in the sewage and earth impurity, and the treatment effect is good, and low cost, especially adapted city uses widely on a large scale. And through the first energy dissipation plate 5 and the second energy dissipation plate 6 that set up, can make sewage impact on the energy dissipation plate at first when sewage intensity is very big, then the velocity of flow can reduce when entering into left filtering ponds 4, has played certain energy dissipation effect, and some large granule pollutant can be held back by second energy dissipation plate 6, discharges through first mud discharging port 12, and the small granule pollutant in the left filtering ponds 4 can discharge through second mud discharging port 13.

Most preferably, in order to further improve the filtering effect of the left filtering tank 4, a detachable filtering net 14 may be obliquely arranged in the left filtering tank 4 to the right, and the filtering net 14 may be clamped with the left filtering tank 4, so as to detachably connect the filtering net 14 with the left filtering tank 4, and of course, other detaching manners may also be adopted, which are not illustrated here by way of example. As shown in fig. 1, the filter screen 14 is disposed obliquely to the right, and the specific angle of inclination of the filter screen 14 may be determined according to the size of the left filter tank 4, which is not limited herein. The filter screen 14 divides the left filter tank 4 into an upper water outlet area 15 and a lower filter area 16, and the water outlet 11 is located on the left side wall of the upper water outlet area 15. Thereby the device is when filtering sewage and collecting, and the pollutant can be held back in filter screen 14 below, and when the pollutant gathering was more, the pollutant can drop automatically, filters when collecting and stopping, can become the backwash water at the sewage of filter screen 14 top automatically, consequently need not often to wash filter screen 14, has saved manpower and materials. Specifically, the filter screen 14 includes a first stainless steel screen, a non-woven fabric layer, and a second stainless steel screen from top to bottom in sequence, and a specific structural diagram is not shown in the drawing, which is only a preferred manner, and filter screens with other structural forms may also be adopted, which are not illustrated here by way of example.

Further, in order to make the water flow condition in the lower filtering area 16 more stable, the bottom of the right water inlet tank 3 can horizontally extend to form a guide plate 19 in the left filtering tank 4, as shown in fig. 5 and 6, after the guide plate 19 is arranged, the vortex flow direction in the upper left of the lower filtering area 16 originally moves to the middle and lower part, and the density of the streamline becomes thinner, which shows that although the vortex still exists, the turbulent flow can become smaller, and the water flow velocity is lower at the position where the vortex is generated, so that the effect of reducing the vortex is achieved through the arranged guide plate 19, and the precipitation effect is increased.

The present invention is not limited to the above-mentioned examples, and various modifications and changes which can be made by those skilled in the art without creative efforts are protected by the present patent within the scope defined by the claims of the present invention.
