Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater filtration and recycling device. Background Technology

[0002] With the rapid growth of urban population and the continuous increase in industrial activities, wastewater discharge has risen sharply, putting enormous pressure on urban water treatment and water resource recycling systems. Traditional wastewater treatment methods, such as direct discharge or discharge after simple treatment, not only waste a large amount of reusable water resources, but may also cause serious pollution to natural water bodies, affecting the ecological environment and public health.

[0003] In existing technologies, wastewater filtration, as a key step in physical treatment, plays a crucial role in removing suspended solids, colloidal substances, and some dissolved substances from wastewater. However, traditional filtration devices often suffer from low filtration efficiency, high maintenance costs, and large footprints, making it difficult to meet the demands of modern wastewater treatment. Therefore, there is a need to develop a more efficient and energy-saving wastewater filtration and recycling device to achieve the resource utilization of wastewater. Utility Model Content

[0004] This invention provides a wastewater filtration and recycling device to solve at least one of the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model is as follows: a wastewater filtration and recycling device, including a filter container and a sedimentation container. The top of the filter container is provided with a filter container cover plate, and the filter container cover plate is provided with a water inlet that cooperates with a sewage pipe. A filter device is formed inside the filter container, and a water outlet is formed on the side wall of the filter container. The water outlet is connected to the sedimentation container through a clean water pipe. A sedimentation tank is provided inside the sedimentation container, and multiple water outlet holes are distributed above the sedimentation tank. A drain outlet that cooperates with a recirculation pipe is formed on the side wall of the sedimentation container.

[0006] Preferably, the filtration device includes a pre-filter, a fine filter, and a fine filter.

[0007] Preferably, the sedimentation tank is provided with multiple lifting devices on its outer side, the base of the lifting device is installed at the bottom of the sedimentation container, and the top of the lifting device is connected to the bottom edge of the sedimentation tank.

[0008] Preferably, the sedimentation tank is funnel-shaped, with a drain outlet at the bottom and a cleaning outlet at the bottom that matches the drain outlet.

[0009] Preferably, the inner wall of the sedimentation container is provided with multiple spray mechanisms.

[0010] Preferably, the filter container has an impurity outlet on its side wall.

[0011] Preferably, the filter container is provided with a cleaning mechanism that cooperates with the impurity outlet, the cleaning mechanism including a cleaning arm, a sliding mechanism, and a cleaning head.

[0012] Preferably, an ozone generator is connected to the recirculation pipeline.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] This invention completes two stages of wastewater treatment through a filtration device in a filtration container and a sedimentation tank in a sedimentation container. The filtration device consists of a pre-filter, a fine filter, and a fine filter, forming a three-stage filtration system that effectively removes impurities and harmful substances from the water. A sedimentation device designed to work in conjunction with the sedimentation tank facilitates the cleaning of various substances remaining in the sedimentation container. The treated wastewater is then reused through a recirculation pipeline, significantly reducing the waste of water resources.

[0015] As a preferred embodiment of this utility model, the funnel-shaped sedimentation tank design effectively collects and discharges sludge layer impurities. The spray mechanism installed on the side wall of the sedimentation container can spray various cleaning solvents and water to clean the scale and stubborn impurities on the sedimentation tank. Combined with the cleaning port at the bottom of the sedimentation container, all cleaning substances are discharged in a unified manner, reducing the contact of workers and lowering labor costs.

[0016] In a preferred embodiment of this utility model, an openable impurity outlet is provided on the side wall of the filter container. When a certain volume of impurities accumulates on the filter device, a cleaning mechanism can be used to clean the impurities on the surface of the filter device, allowing the impurities to be discharged through the impurity outlet. The opening of the impurity outlet makes the maintenance and replacement of the three-layer filter screen more efficient and reduces time costs.

[0017] As a preferred embodiment of this utility model, an ozone device is added to the recirculation pipeline to further clean the recycled water, oxidize and decompose colored substances and odors into harmless substances, and expand the scope of use of recycled water.

[0039] Example 1

[0040] like Figure 1 , Figure 2As shown, a wastewater filtration and recycling device is described. Wastewater enters through the filter container cover 11 via the sewage pipe 121. The wastewater undergoes its first treatment in the filtration device 2 to form filtered water. The pre-filter 211, fine filter 212, and fine filter 213 remove suspended solids, impurities, and some dissolved substances from the wastewater. The filter container 1 and the sedimentation container 3 are connected by a clean water pipe 5. The filtered water flows into the clean water pipe 5 through the outlet 13 and is then pumped by the water pump 51 through the inlet 32 ​​into the sedimentation container 3. The filtered water collects in the sedimentation tank 4 for settling, separating the residual micro-suspended matter and colloidal matter. During the settling process, the bottom of the sedimentation tank 4 is in contact with the bottom of the sedimentation container 3. The upper part of the sedimentation tank 4 has an outlet 42, which is blocked by the side wall of the sedimentation container 3 to ensure that the filtered water does not overflow before the settling is complete. The sedimentation container 3 is topped with a sedimentation container cover 31, which is a visible structure that allows for easy observation of the sedimentation process. After sedimentation, the sedimentation tank 4 is lifted by the lifting device 41, which includes a reducer, gear set, screw, and nut. The reducer and gear set convert the rotary motion into linear motion, driving the screw to rotate. The screw and nut work together to make the nut move linearly along the screw, causing the sedimentation tank 4 to rise or fall. During the lifting process, the outlet hole 42 gradually moves away from the obstruction of the side wall of the sedimentation container 3, and the filtered water that has completed sedimentation flows out of the sedimentation tank 4 to form recycled water. Suspended matter and colloidal matter form a sludge layer at the bottom of the sedimentation tank 4 through sedimentation. The valve 62 is opened, and the recirculation pump 61 is started to pump the recycled water into the recirculation pipe 6 through the drain outlet 33, completing the filtration, recycling, and reuse of wastewater.

[0041] Example 2

[0042] like Figure 3 , Figure 4 As shown, a wastewater filtration and recycling device differs from Embodiment 1 in that the bottom of the sedimentation tank 4 is designed in a funnel shape to facilitate the concentrated accumulation of sludge. Due to water scouring, scale easily forms in the outlet 42, affecting drainage efficiency. When the sludge layer and water ditch accumulate to a certain extent, the sedimentation tank 4 is raised by the lifting device 41, and the spray mechanism 44 installed on the side wall of the sedimentation container 3 is activated to spray cleaning solvent. After standing for a period of time to allow the scale to fully dissolve, the recycled water is transported to the spray mechanism through the circulating water pump 641 and the circulating water pipe 64. 44. Re-start the spraying mechanism 44 to spray recycled water, achieving efficient utilization of water resources. Clean the side wall of the sedimentation tank 4. After cleaning the side wall, lower the sedimentation tank 4 to the bottom of the sedimentation container 3 via the lifting device 41. During this process, the spraying mechanism 4 continues to work. The bottom of the sedimentation tank 4 is equipped with a drain outlet 43, which is connected to the bottom cleaning outlet 34 of the sedimentation container 3. The sludge is discharged through the cleaning outlet 34, and clean water is used to perform simple cleaning of the accumulated impurities in the sedimentation container 3 and the stubborn substances at the bottom of the sedimentation tank 4.

[0043] Example 3

[0044] like Figure 5 , Figure 6 As shown, a wastewater filtration and recycling device, different from Embodiment 1, has an impurity outlet 14 on the side wall of the filter container 1, and a cleaning mechanism 22 is formed inside the filter container 1. When the impurity outlet is opened, the cleaning arm 221 moves through the sliding mechanism 222 installed on the side wall of the filter container 1. During the movement, the cleaning head 223 drives the accumulated impurities to move towards the impurity outlet 14 to complete the cleaning of impurities. The impurity outlet 14 is used to replace and maintain the pre-filter 211, fine filter 212 and fine filter 213.

[0045] Example 4

[0046] like Figure 7 As shown, a wastewater filtration and recycling device differs from Embodiment 1. Wastewater undergoes sedimentation treatment in sedimentation container 3. After valve 62 is opened, recirculation pump 61 pumps the recycled water into recirculation pipe 6 through drain outlet 33. At this time, some colored substances and odors remain in the recycled water. An ozone mechanism 63 is connected to the recirculation pipe 6. The ozone mechanism 63 includes an ozone generator 631 and an ozone aerator 632. The ozone aerator 632 is installed in the recirculation pipe 6 and connected to the ozone generator 631 through a pipe. The ozone generated by the ozone generator 631 is transported to the ozone aerator 632 through the pipe. The ozone aerator 632 injects ozone into the recycled water in the form of microbubbles, which react with the colored substances and odor components in the recycled water, oxidizing and decomposing them into harmless substances, thus completing the final treatment of the wastewater.
