Description

Technical Field

[0001] The utility model relates to the technical field of sludge separation, and more specifically, the utility model relates to an environment-friendly sludge separation device. Background Art

[0002] With the acceleration of the urbanization process, especially the accumulation of sludge in rivers, lakes and reservoirs, it has brought challenges to the ecological environment and the sustainable utilization of water resources. The sludge mainly comes from industrial wastewater, domestic sewage, agricultural runoff, etc.;

[0003] After retrieval, the existing patent (publication number: CN111705860A) discloses an environment-friendly sludge separation and cleaning device for water conservancy projects, including a workbench, a sludge stirring tank and a separation tank. The top of the workbench is fixedly connected with a sludge stirring tank, the bottom of the workbench is fixedly connected with a separation tank, a muddy water separation plate is fixedly connected inside the separation tank, a vibration motor is fixedly connected to the bottom of the muddy water separation plate, and a sand-water separation plate is arranged below the muddy water separation plate; the blades at the dredging rollers on the sliding frame are in contact with the sludge on the muddy water separation plate, so that the blades are driven by the moving sliding frame to rotate, and the rotating blades dredge the sludge, so that the water and sand in the sludge can quickly pass through the separation plate, and the blockage of the sludge is effectively avoided. Since the sludge is dredged by the blades on the dredging rollers, the trouble of adding a large amount of water for separation is avoided, so as to achieve the purpose of energy conservation and environmental protection. The inventor found the following problems in the process of realizing the utility model:

[0004] The existing sludge separation and cleaning device usually contains dirt such as suspended matter and sludge in the sewage. However, after each separation, although the concentration of dirt in the sewage will decrease, due to the different types of suspended matter and sludge, the single separation treatment time is not enough for all suspended matter and sludge to fully settle or be intercepted, and there will be a phenomenon of residual dirt, resulting in the inability to effectively remove dirt such as suspended matter and sludge. Moreover, with the increasingly strict environmental protection regulations, the requirements for sewage treatment and discharge are also getting higher and higher. Single separation cannot ensure that the separated water source meets the standards every time it is discharged, resulting in treatment risks;

[0005] Therefore, an environment-friendly sludge separation device is proposed for the above problems. Content of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an environment-friendly sludge separation device to solve the problems put forward in the above background art.

A fixed partition is arranged on the left side of the inner cavity of the separation tank. A filter screen is installed above the fixed partition. A water delivery pipe is provided at the lower end on the left side of the separation tank. One end of the water delivery pipe is provided with a water pump.

[0008] A water storage tank is arranged below the separation tank. A water extraction pipe is provided at the lower end on the left side of the water storage tank. The upper end of the water extraction pipe is provided with a circulating water pump. The circulating sewage pipe is arranged at the output end of the circulating water pump.

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further elaborated in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described below:

[0027] As a preferred embodiment, a sludge discharge pipe 7 is provided at the lower part on the right side of the separation tank 3. One end of the sludge discharge pipe 7 protrudes from the outer surface of the separation housing 1, and a sludge pump 14 is provided at the center of the sludge discharge pipe 7. Further, the sludge pump 14 pumps out the sludge in the separation tank 3 through the sludge discharge pipe 7, so as to facilitate the subsequent treatment of the sludge.

[0028] As a preferred embodiment, the filter screen 6 is made of metal. The input end of the water pump 9 is connected to the water delivery pipe 8, and the output end of the water pump 9 is connected to the water storage tank 10. Further, the metal filter screen 6 can filter sludge and suspended matter, reduce the turbidity of the water body, and improve the transparency and clarity of the water. The water pump 9 can pump out the water in the separation tank 3 through the water delivery pipe 8 and send it into the water storage tank 10 through the output end.

[0029] As a preferred embodiment, a drain pipe 15 is provided at the lower end on the right side of the water storage tank 10, and a valve 16 is provided on the outer surface of the drain pipe 15. Further, the drain pipe 15 discharges the water source in the water storage tank 10 under the control of the valve 16.

[0030] As a preferred embodiment, the shape of the feed inlet 2 is funnel-shaped, and the end of the circulating sewage pipe 13 far from the circulating water pump 12 is close to the upper part of the feed inlet 2. Further, the funnel-shaped feed inlet 2 can facilitate the downward flow of sewage, and the circulating sewage pipe 13 is close to the feed inlet 2 to discharge the sewage back into the feed inlet 2 for separation.

[0031] As a preferred embodiment, a motor 17 is provided on the right side of the water storage tank 10. A stirring rod 18 is installed on the right side inside the water storage tank 10, and the output end of the motor 17 is connected to the stirring rod 18. Further, the motor 17 can drive the stirring rod 18 to perform a stirring operation, thereby preventing impurities from settling and facilitating the circulation water pump 12 to better pump out the water source with impurities.

[0032] The working process of the present utility model is as follows: First, the sewage enters the separation housing 1 through the feed port 2, which is funnel-shaped to ensure the rapid inflow of sewage. It is connected to the separation tank 3 below through the connection port 4. The sewage enters the inside of the separation tank 3. The sewage flows in the inner cavity of the separation tank 3. The bottom of the separation tank 3 is partitioned by the fixed partition 5 to prevent the settled sludge from entering the left side of the fixed partition 5. The water pump 9 pumps out the clear water on the other side of the filter screen 6 through the water delivery pipe 8. Since the water pump 9 is pumping water, the water flow will flow to the left side of the filter screen 6. The filter screen 6 above the water flow partition intercepts the solid particles and suspended matters in the water, forcing the heavier sludge to settle to the bottom of the separation tank 3 due to gravity. The filtered water is sent to the lower water storage tank 10. A sludge discharge pipe 7 is provided on the right side of the separation tank 3, and a sludge pump 14 is equipped to periodically pump out the separated deposited sludge as needed. The sludge is discharged from the separation housing 1 through the sludge discharge pipe 7 for subsequent treatment. The water in the water storage tank 10 is pumped out by the circulation water pump 12 through the water extraction pipe 11, transported to the circulating sewage pipe 13, and then sent back to the feed port 2. The motor 17 can drive the stirring rod 18 to perform a stirring operation, thereby preventing impurities from settling and facilitating the circulation water pump 12 to better pump out the water source with impurities. Multiple cycles of separation can be carried out according to needs, thereby effectively increasing the water treatment time and optimizing the separation effect. After multiple cycles, the drain pipe 15 of the water storage tank 10 is opened through the control valve 16 to discharge the water source for subsequent treatment. The sludge and suspended matter residues in the effluent are significantly reduced, and it can meet more stringent environmental protection discharge standards, suitable for reuse or safe discharge. The above is the working principle of this environmentally friendly sludge separation device.
