Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment and recycling device with multi-stage filtration function. Background Technology

[0002] Wastewater reuse is an important way to achieve sustainable water resource recycling. Its core is the deep treatment of wastewater through physical, chemical, and biological methods to remove suspended solids, organic matter, oils, and other pollutants, bringing the water quality up to reuse standards. This process not only alleviates water shortage pressures but also significantly reduces the pollution load on natural water bodies, achieving both environmental and economic benefits. Common reuse treatment methods include sedimentation, filtration, membrane separation, adsorption, and biochemical degradation. Among these, multi-stage filtration and oil-water separation technologies are particularly crucial, directly affecting effluent quality and reuse feasibility.

[0003] Traditional filtration units in existing wastewater treatment equipment mostly adopt single-stage or simple combined structures. The filter media is prone to clogging, requiring frequent backwashing, and has limited ability to retain small particles and emulsified oil, resulting in low filtration efficiency and insufficient operational stability. On the other hand, oil-water separation processes mostly rely on gravity separation or conventional coalescence technology, which is ineffective at separating low-concentration floating oil and dispersed oil droplets. This can easily leave oily substances in the water, affecting subsequent processes and even the safety of recycled water.

[0004] Therefore, there is an urgent need for a wastewater treatment and reuse equipment with multi-stage filtration capabilities. Utility Model Content

[0005] In order to overcome the shortcomings of existing sewage treatment equipment such as low filtration efficiency and poor oil-water separation effect, this utility model provides a sewage treatment and recycling equipment with multi-stage filtration function.

[0006] The technical solution is as follows: A wastewater treatment and reuse equipment with multi-stage filtration function includes a support frame, a filter barrel, a discharge pipe, a solenoid valve, a feed pipe, a transmission assembly, and a rotating assembly. The filter barrel is fixedly fitted onto the upper part of the support frame. The discharge pipe is fixedly connected to the bottom of the filter barrel, and a solenoid valve is fixedly installed on the discharge pipe. The feed pipe is fixedly connected to the rear top of the filter barrel. The transmission assembly is located on the filter barrel, and the rotating assembly is located inside the filter barrel. A hole is opened on the rear upper part of the filter barrel. The equipment also includes a filter disc, a connecting frame, a filter screen, a second filter screen, a collection frame, an oil drain pipe, activated carbon, and a scraper. A filter disc is rotatably connected to the lower part of the filter barrel. A connecting frame is fixedly connected to the bottom of the filter disc. A filter screen is installed in the middle of the connecting frame. A collection frame is rotatably connected inside the connecting frame. A filter screen is fixedly connected between the upper part of the collection frame and the bottom of the filter disc. An oil drain pipe is fixedly connected to the collection frame. The right end of the oil drain pipe extends into the filter barrel. Activated carbon is placed at the bottom of the collection frame. A scraper is rotatably connected to the center of the collection frame. Through the initial interception of large particles by the filter disc, the secondary filtration by the filter screen, and the fine filtration by the filter screen, a multi-stage physical filtration system is formed, which purifies the sewage step by step and significantly improves the quality of the effluent.

[0007] Preferably, it also includes a housing, with the housing installed on the front side of the top of the filter canister.

[0008] Preferably, the transmission assembly includes a first bevel gear, a motor, and a second bevel gear. The first bevel gear is fixedly connected to the top of the scraper, and the motor is fixedly installed on the right side of the middle part of the filter barrel. The output shaft of the motor is fixedly connected to the second bevel gear, which is located inside the filter barrel, and the first bevel gear and the second bevel gear mesh with each other.

[0009] Preferably, the filter also includes a second filter disc, a stirring blade, a third bevel gear, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a fourth bevel gear. The second filter disc is placed in the upper part of the filter barrel. A stirring blade is rotatably connected to the center of the top of the filter barrel. A third bevel gear is fixedly connected to the top of the stirring blade. A first synchronous pulley is fixedly connected to the output shaft of the motor. A second synchronous pulley is rotatably connected to the outer casing. A synchronous belt is wound between the first and second synchronous pulleys. A fourth bevel gear is fixedly connected to the left side of the second synchronous pulley. The third and fourth bevel gears mesh with each other. Both the third and fourth bevel gears are located inside the outer casing.

[0010] Preferably, the rotating assembly includes a first bevel gear, a gear ring, and a second bevel gear. The first bevel gear is fixedly connected to the bottom of the first bevel gear, the gear ring is fixedly connected to the lower inner edge of the connecting frame, and the second bevel gear is rotatably connected to the lower part of the connecting frame. The first bevel gear meshes with the second bevel gear, and the second bevel gear meshes with the gear ring.

[0011] Preferably, the filter also includes a handle, which is fixedly connected to the filter disc and is located outside the holes on the filter barrel.

[0012] The beneficial effects of this utility model are as follows: By setting up a transmission component and a rotating component, the motor simultaneously drives the stirring blades to agitate the sewage, preventing the second filter disc from clogging and ensuring continuous preliminary filtration. After preliminary filtration by the second filter disc, the sewage flows into the first filter disc. The rotating component drives the first filter disc and the connecting frame to rotate, using centrifugal force to promote oil-water separation. The grease is adsorbed by the activated carbon and scraped by the scraper to the collection frame, and then discharged through the oil drain pipe, thereby improving the filtration efficiency and the effect of oil-water separation.

A connecting frame 30 is fixedly connected to the bottom of the filter disc 3. A filter screen 302 is provided in the middle of the connecting frame 30. A collection frame 31 is rotatably connected inside the connecting frame 30. A filter screen 301 is fixedly connected between the upper part of the collection frame 31 and the bottom of the filter disc 3. An oil drain pipe 310 is fixedly connected to the collection frame 31. The right end of the oil drain pipe 310 extends into the filter barrel 2. Activated carbon 32 for adsorbing oil is placed at the bottom of the collection frame 31. A scraper 33 is rotatably connected to the center of the collection frame 31.

[0020] like Figures 1-2 As shown, it also includes a housing 23, which is installed on the front side of the top of the filter barrel 2.

[0021] like Figures 2-4 As shown, the transmission assembly includes a first bevel gear 34, a motor 35, and a second bevel gear 36. The first bevel gear 34 is fixedly connected to the top of the scraper 33. The motor 35 is installed on the right side of the middle part of the filter barrel 2 by screws. The output shaft of the motor 35 is fixedly connected to the second bevel gear 36. The second bevel gear 36 is located inside the filter barrel 2, and the first bevel gear 34 and the second bevel gear 36 mesh with each other.

[0022] like Figures 2-3 As shown, it also includes a filter disc 2 4, a stirring blade 41, a bevel gear 3 42, a synchronous pulley 1 43, a synchronous pulley 2 44, a synchronous belt 45, and a bevel gear 46. The filter disc 2 4 is placed in the upper part of the filter barrel 2. The stirring blade 41 is rotatably connected to the center of the top of the filter barrel 2. The bevel gear 3 42 is fixedly connected to the top of the stirring blade 41. The synchronous pulley 1 43 is fixedly connected to the output shaft of the motor 35. The synchronous pulley 2 44 is rotatably connected to the outer casing 23. The synchronous belt 45 is wound between the synchronous pulley 1 43 and the synchronous pulley 2 44. The bevel gear 46 is fixedly connected to the left side of the synchronous pulley 2 44. The bevel gear 3 42 and the bevel gear 46 mesh with each other. The bevel gear 3 42 and the bevel gear 46 are both located inside the outer casing 23, which can protect the bevel gear 3 42 and the bevel gear 46.

[0023] like Figure 5As shown, the rotating assembly includes a first spur gear 5, a gear ring 51, and a second spur gear 52. The bottom of the first bevel gear 34 is fixedly connected to the first spur gear 5. The gear ring 51 is fixedly connected to the lower inner edge of the connecting frame 30. The second spur gear 52 is rotatably connected to the lower part of the connecting frame 30. The first spur gear 5 meshes with the second spur gear 52, and the second spur gear 52 meshes with the gear ring 51.

[0024] like Figure 3 As shown, it also includes a handle 401. The handle 401 is fixedly connected to the filter disc 2. The handle 401 is located outside the hole on the filter barrel 2, making it easy for the operator to remove the filter disc 2.

[0025] When the operator uses this device to filter wastewater, the motor 35 is first started, and the wastewater to be treated is poured into the filter tank 2 through the feed pipe 24. The output shaft of the motor 35 rotates, driving the synchronous pulley 43 to rotate. Through the synchronous belt 45, the bevel gear 46 rotates, which in turn drives the bevel gear 42 that meshes with it to rotate. The bevel gear 42 drives the stirring blade 41 to agitate the wastewater. This process effectively prevents impurities from clogging the filter disc 4 while initially filtering the wastewater. When the initially filtered wastewater flows into the filter disc 3 through the filter disc 3, the output shaft of the motor 35 simultaneously drives the bevel gear 36 to rotate the bevel gear 34. The bevel gear 34 is linked to the scraper 33 to rotate, and the scraper 33 drives the spur gear 5 to rotate. The spur gear 5 meshes with the spur gear 2 52, causing the gear ring 51 to rotate, which in turn drives the filter disc 3 and the connecting frame 30 to rotate synchronously. At this point, the wastewater flowing into the collection frame 31 is adsorbed by the activated carbon 32, and the grease is trapped inside the collection frame 31. Simultaneously, the centrifugal force generated by the rotation of the filter disc 3 and the connecting frame 30 promotes oil-water separation. The grease floats on the water surface and is scraped into the collection frame 31 by the rotating scraper 33, and finally discharged through the oil drain pipe 310. After the wastewater treatment is completed, the operator can open the solenoid valve 22 to remove the purified water; finally, the filter disc 4 is removed by the handle 401, the trapped impurities are cleaned, and the filter disc is reset to complete the entire operation process.
