Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for a garden viewing pond. Background Technology

[0002] As an important component of the garden landscape system, the garden viewing pond not only serves a decorative function, but its water clarity and ecological stability directly affect the overall landscape effect and visitor experience. Because viewing ponds are exposed to the natural environment for extended periods, they are prone to turbidity and algae growth due to factors such as fallen leaves, dust, microbial proliferation, and visitor activities. If not treated promptly, this can damage the aesthetic appeal of the landscape and even lead to water quality deterioration. Therefore, wastewater treatment for garden viewing ponds requires a systematic process to purify the water. Microfiltration machines are widely used as key pretreatment equipment, effectively intercepting suspended solids, fine particulate matter, algal spores, and other impurities in the water, initially reducing turbidity and pollutant content. The wastewater is then sent to biological filters, ultraviolet disinfection devices, or water balancing systems for further treatment, ensuring that the water meets the requirements of transparency, cleanliness, and ecological safety for garden viewing ponds, achieving the recycling and long-term maintenance of the landscape water.

[0003] However, during the use of the microfiltration machine, it was found that when sewage is injected, impurities tend to accumulate in a certain area of ​​the filter screen, causing severe local clogging and affecting the overall filtration efficiency. In addition, for those complex, highly adhesive, and clumped impurities on the filter screen, existing devices mostly rely on a single backwashing method for cleaning. The backwashing water flow is insufficient to completely remove them from the filter screen, which will cause the filter screen's filtration capacity to continuously decline over time, requiring frequent shutdowns for maintenance and increasing maintenance costs and workload. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a sewage treatment device for garden viewing ponds to solve the above-mentioned shortcomings in the prior art.

[0005] Technical solution: A wastewater treatment device for a garden viewing pond includes a microfilter body. A fixed disc is installed inside the microfilter body. A connecting ring is rotatably connected to the fixed disc. An annular filter screen for filtering wastewater is installed on the connecting ring. The microfilter body also includes a backwashing mechanism, a rotating mechanism, and a washing mechanism. The rotating mechanism and the washing mechanism are connected by a transmission component.

[0006] The washing mechanism includes a rotating shaft and a roller brush. The rotating shaft is rotatably connected to a fixed disc, and the rotating shaft is fixedly connected to the roller brush.

[0007] As a further description of the above technical solution: the rotating mechanism includes a drive shaft rotatably connected to the microfilter body, and a servo motor for driving the drive shaft to rotate is provided on the outer wall of the microfilter body. A first gear is provided on the drive shaft, and an external gear ring is provided on the outer wall of the connecting ring. The first gear meshes with the external gear ring.

[0008] As a further description of the above technical solution: the transmission assembly includes an internal gear ring and a second gear;

[0009] The internal gear ring is fixedly connected to the inner wall of the connecting ring, while the second gear is fixedly connected to the rotating shaft, and the internal gear ring and the second gear are meshed together.

[0010] As a further description of the above technical solution: the backwashing mechanism includes a water guide pipe disposed on the main body of the microfilter, and a high-pressure nozzle for rinsing impurities on the annular filter screen is disposed on the water guide pipe.

[0011] As a further description of the above technical solution: the main body of the microfilter is also provided with a water inlet pipe, and a number of diversion pipes are provided through the water inlet pipe, and the diversion pipes are located inside the annular filter screen.

[0012] As a further description of the above technical solution: a sewage pipe is provided through the main body of the microfilter, and a guide groove is provided through the sewage pipe, and the guide groove is located inside the annular filter screen.

[0013] As a further description of the above technical solution: several high-pressure nozzles are provided and are arranged at equal intervals on the water guide pipe, and the water guide pipe and the high-pressure nozzles are located outside the annular filter screen.

[0014] As a further description of the above technical solution: the rotating shaft and roller brush are located inside the annular filter screen, and the rotating shaft and roller brush are arranged directly above the guide groove.

[0015] As a further description of the above technical solution: a drain outlet is provided through the side wall of the microfiltration machine body near the bottom.

[0016] Beneficial effects: By driving the annular filter screen to rotate through the rotating component, impurities in the wastewater can be evenly distributed on the annular filter screen, effectively avoiding the problem of localized filter screen blockage caused by localized accumulation of impurities. Furthermore, the rotating mechanism is connected to the washing mechanism through the transmission component. While the annular filter screen rotates, the internal gear ring drives the No. 2 gear to rotate, causing the rotating shaft to drive the roller brush to rotate inside the annular filter screen. This, combined with the high-pressure nozzle of the backwashing mechanism to rinse from the outside, forms a coordinated cleaning mode from the inside and outside, greatly improving the cleaning effect of the filter screen.

Detailed Implementation

[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-4 A wastewater treatment device for a garden viewing pond includes a microfilter body 1. A fixed disc 2 is provided inside the microfilter body 1. A connecting ring 17 is rotatably connected to the fixed disc 2. An annular filter screen 3 for filtering wastewater is provided on the connecting ring 17. The microfilter body 1 also includes a backwashing mechanism, a rotating mechanism, and a washing mechanism. The rotating mechanism and the washing mechanism are connected by a transmission component.

[0025] The washing mechanism includes a rotating shaft 9 and a roller brush 10. The roller brush 10 cleans the sludge on the inner wall of the annular filter screen 3. The rotating shaft 9 is rotatably connected to the fixed disc 2. The rotating shaft 9 and the roller brush 10 are fixedly connected. The rotating mechanism drives the annular filter screen 3 to rotate, and the transmission mechanism drives the rotating shaft 9 to rotate inside the annular filter screen 3. The rotating shaft 9 drives the roller brush 10 to rotate and brush the inner side of the backwashing part of the backwashing mechanism. This solves the problem that the impurities in the sewage are complex in nature, and some highly adhesive impurities agglomerate into clumps, which are difficult to be effectively removed by the backwash water. Existing devices only use a single impact method, which has a poor cleaning effect and leads to a decrease in the filtration efficiency of the filter screen.

[0026] Furthermore, the rotating mechanism includes a drive shaft 4 rotatably connected to the microfilter body 1, and a servo motor for driving the drive shaft 4 to rotate is provided on the outer wall of the microfilter body 1. This is an existing product, which is used by connecting to an external power supply. A first gear 5 is provided on the drive shaft 4, and an external gear ring 6 is provided on the outer wall of the connecting ring 17. The first gear 5 and the external gear ring 6 are meshed together. By starting the servo motor, the drive shaft 4 is driven to rotate, and then the rotation of the first gear 5 and the external gear ring 6 drives the connecting ring 17 to rotate. The connecting ring 17 drives the annular filter screen 3 to rotate. During the process of injecting sewage into the inner side of the annular filter screen 3, the annular filter screen 3 is rotated, so that the impurities in the sewage are evenly distributed on the annular filter screen 3, avoiding the problem of local accumulation in a certain place.

[0027] Furthermore, the transmission assembly includes an internal gear ring 7 and a second gear 8;

[0028] The internal gear ring 7 is fixedly connected to the inner wall of the connecting ring 17, while the second gear 8 is fixedly connected to the rotating shaft 9. The internal gear ring 7 and the second gear 8 are meshed together, which can drive the internal gear ring 7 to rotate while the connecting ring 17 and the annular filter screen 3 rotate. The internal gear ring 7 drives the second gear 8 to rotate, thereby driving the washing mechanism to work.

[0029] Furthermore, the backwashing mechanism includes a water guide pipe 12 installed on the main body 1 of the microfilter. The water guide pipe 12 is equipped with a high-pressure nozzle 13 for rinsing impurities on the annular filter screen 3. It should be noted that the water guide pipe 12 is equipped with a connecting flange, which is connected to an external water pump to deliver water into the interior of the water guide pipe 12. Water is then sprayed onto the outer surface of the annular filter screen 3 from the nozzle of the high-pressure nozzle 13 to rinse the impurities and sludge on the annular filter screen 3.

[0030] Furthermore, an inlet pipe 15 is also provided through the main body 1 of the microfilter. Several branch pipes 19 are provided through the inlet pipe 15, and the branch pipes 19 are located inside the annular filter screen 3. It should be noted that the end of the inlet pipe 15 is also provided with a connecting flange, which is connected to a water pump to pump the sewage inside the garden viewing pool into the inlet pipe 15, and then flow through the branch pipes 19 to the inside of the annular filter screen 3 for filtration.

[0031] Furthermore, a sewage pipe 14 is provided through the main body 1 of the microfilter, and a guide channel 11 is provided through the sewage pipe 14. The guide channel 11 is located inside the annular filter screen 3. The sewage flushed by the backwashing mechanism and the impurities washed off by the washing mechanism are collected by the guide channel 11 and discharged through the sewage pipe 14.

[0032] Furthermore, several high-pressure nozzles 13 are provided and are arranged at equal intervals on the water guide pipe 12, and the water guide pipe 12 and the high-pressure nozzles 13 are located outside the annular filter screen 3.

[0033] Furthermore, the rotating shaft 9 and the roller brush 10 are located inside the annular filter screen 3, and the rotating shaft 9 and the roller brush 10 are positioned directly above the guide groove 11. The high-pressure nozzle 13 impacts the high-pressure water flow onto a designated position on the annular filter screen 3, while the roller brush 10 is located inside the annular filter screen 3 where it is impacted by the water flow, cleaning out the difficult-to-clean sludge and impurities from the inside of the annular filter screen 3. The guide groove 11 located directly below catches the sewage and sludge.

[0034] Furthermore, a drain outlet 18 is provided through the side wall near the bottom of the microfilter body 1 for discharging the filtered wastewater and transferring it to the next treatment process.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
