Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a suspended filtration device. Background Technology

[0002] When untreated wastewater is discharged into water bodies, suspended solids can lead to sludge deposition and the formation of anaerobic conditions, thereby disrupting aquatic ecosystems. Furthermore, suspended solids may carry pathogens, posing a threat to public health. The presence of suspended solids increases the burden on subsequent treatment processes. For example, in the biological treatment stage, suspended solids may interfere with the activity of microorganisms, reducing treatment efficiency. Pretreatment to remove suspended solids provides cleaner water for subsequent biological treatment, thus improving overall treatment effectiveness.

[0003] In existing technologies, when treating suspended solids in wastewater, if the influent is a direct impact type, local turbulence is easily formed in the filtration tank. This not only disturbs the settled suspended solids, causing secondary upwelling, but also makes it difficult to achieve uniform water flow distribution, resulting in poor sedimentation of suspended solids. Some fine suspended solids overflow with the water, affecting treatment efficiency. Furthermore, the filter screens or grids used for interception are easily clogged by suspended solids during long-term operation. If they are not cleaned in time, the water flow capacity will be reduced, requiring frequent shutdowns for manual cleaning, which increases maintenance costs and affects the stability of continuous treatment. Therefore, we propose a suspended filtration device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a suspended filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suspended filtration device includes a filtration tank, an inner plate fixedly connected inside the filtration tank, an L-shaped water inlet pipe fixedly embedded in the outer wall of the inner plate, an inner ring fixedly fitted on the outer wall of the L-shaped water inlet pipe, a stainless steel mesh fixedly fitted on the outer wall of the inner ring, an outer ring fixedly fitted on the outer wall of the stainless steel mesh, the outer wall of the outer ring being fixedly connected to the inner wall of the filtration tank, four legs fixedly connected to the bottom of the filtration tank, a common support plate fixedly connected between the four legs, a geared motor fixedly connected to the top of the support plate, and a filtration assembly inside the filtration tank.

[0007] Preferably, the filter assembly includes a drive shaft, the top of the output shaft of the geared motor is fixedly connected to the bottom of the drive shaft, a conical diverter is fixedly connected to the top of the drive shaft, two rectangular scrapers are fixedly connected to the outer wall of the conical diverter, and multiple stainless steel brushes are evenly fixedly connected to the top of the two rectangular scrapers. By setting the filter assembly, the bottom of the stainless steel interception net is cleaned to avoid obstruction when intercepting suspended matter in the future.

[0008] Preferably, the filter tank is internally fixedly connected to an overflow weir, which ensures the stability of the effluent.

[0009] Preferably, the outer wall of the filter tank is fixedly connected to an outlet pipe.

[0010] Preferably, the bottom of the filter tank is provided with a through hole, the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the geared motor, and the inner wall of the through hole is treated with an existing mechanical seal to ensure the sealing between the output shaft of the geared motor and the through hole.

[0011] Preferably, the top of the stainless steel brush is in contact with the bottom of the stainless steel interception mesh, and a manhole is added to the outer wall of the filter pool to allow for regular maintenance of the stainless steel brush.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution uses an L-shaped inlet pipe in conjunction with a conical diversion plate. After the wastewater is transported downwards, it is diverted through the conical surface, avoiding the local turbulence caused by direct impact inlet. This not only prevents the secondary re-emergence of settled suspended solids, but also achieves uniform water flow distribution, improves the settling effect of suspended solids, reduces the overflow of fine suspended solids with water, and improves treatment efficiency.

[0015] The drive shaft, conical diverter, rectangular scraper, and stainless steel brush are rotated by a geared motor, which can automatically clean the bottom of the stainless steel interception net, avoiding clogging problems, eliminating the need for frequent shutdowns for manual cleaning, reducing maintenance costs, and ensuring the stability of continuous processing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-4 As shown, a suspended filtration device is disclosed, including a filter tank 1. An overflow weir 2 is fixedly connected inside the filter tank 1. An accelerator plate 3 is fixedly connected inside the filter tank 1. An L-shaped water inlet pipe 4 is fixedly embedded in the outer wall of the accelerator plate 3. The accelerator plate 3 provides a stable installation support for the L-shaped water inlet pipe 4 to prevent the L-shaped water inlet pipe 4 from shaking or displacing due to water flow impact during sewage transportation. An outlet pipe 5 is fixedly connected to the outer wall of the filter tank 1.

[0024] The outer wall of the L-shaped inlet pipe 4 is fixedly fitted with an inner ring 6, the outer wall of the inner ring 6 is fixedly fitted with a stainless steel intercepting mesh 7, and the outer wall of the stainless steel intercepting mesh 7 is fixedly fitted with an outer ring 9. The outer wall of the outer ring 9 is fixedly connected to the inner wall of the filter tank 1. The inner ring 6 and the outer ring 9 cooperate to form a double fixation, which enhances the structural stability of the stainless steel intercepting mesh 7 and prevents the stainless steel intercepting mesh 7 from deforming or shifting when impacted by water flow or cleaned by the stainless steel brush 16.

[0025] Four legs 10 are fixedly connected to the bottom of the filter tank 1, supporting the filter tank 1 so that its bottom is off the ground. The same support plate 11 is fixedly connected between the four legs 10. A geared motor 12 is fixedly connected to the top of the support plate 11. A through hole is opened at the bottom of the filter tank 1. The inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the geared motor 12. The contact surface between the through hole and the output shaft of the geared motor 12 is sealed to prevent water leakage.

[0026] The filter tank 1 is equipped with a filter assembly, which includes a drive shaft 13. The top of the output shaft of the geared motor 12 is fixedly connected to the bottom of the drive shaft 13. A conical diverter plate 14 is fixedly connected to the top of the drive shaft 13. The conical surface at the top of the conical diverter plate 14 can evenly divert the sewage transported by the L-shaped inlet pipe 4, so that the water flow spreads in all directions along the conical surface and then flows smoothly downward.

[0027] Two rectangular scrapers 15 are fixedly connected to the outer wall of the conical diversion plate 14. Multiple stainless steel brushes 16 are evenly fixedly connected to the top of the two rectangular scrapers 15. The top of the stainless steel brushes 16 is in contact with the bottom of the stainless steel interception net 7. When the stainless steel brushes 16 rotate, they can effectively clean the suspended matter attached to the surface of the stainless steel interception net 7. An inclined tube 8 is fixedly connected to the outer wall of the filter tank 1. An electronic valve 17 is fixedly installed on the outer wall of the inclined tube 8.

[0028] Working principle: During operation, sewage is pumped into the L-shaped inlet pipe 4 by an existing sewage pump (one end of the L-shaped inlet pipe 4 is fixedly connected to the output end of the sewage pump). The sewage enters the filter tank 1 downwards through the L-shaped inlet pipe 4. The sewage comes into contact with the top of the conical diversion plate 14 and is diverted by the conical surface of the conical diversion plate 14. As the sewage flows upwards, the suspended solids gradually settle to the bottom of the tank because the weight of the suspended solids is greater than the buoyancy and resistance of the water flow. Furthermore, when the sewage passes through the stainless steel interception net 7, the stainless steel interception net 7 also intercepts the suspended solids. The treated sewage flows from the overflow weir 2 to... When treating suspended solids, the sewage pump stops running, and the geared motor 12 drives the drive shaft 13 to rotate. The drive shaft 13 rotates, which in turn drives the conical diverter 14 to rotate. The conical diverter 14 rotates, which in turn drives the two rectangular scrapers 15 to rotate. The two rectangular scrapers 15 rotate, which in turn drives the two sets of stainless steel brushes 16 to rotate. The two sets of stainless steel brushes 16 clean the bottom of the stainless steel interception net 7 to avoid affecting the subsequent interception effect. Then, the electronic valve 17 is opened to discharge the mixture of suspended solids and water in the filter tank 1 through the inclined pipe 8 for separate treatment.

[0029] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 12, electronic valve 17, and sewage pump to facilitate the control of the overall operation.
