Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a self-cleaning circulating water treatment device. Background Technology

[0002] Wastewater treatment equipment is an industrial device that can effectively treat domestic sewage and industrial wastewater in urban areas, preventing sewage and pollutants from flowing directly into water bodies. It is of great significance for improving the ecological environment, enhancing the city's image, and promoting economic development.

[0003] In wastewater treatment systems, the initial treatment unit uses trash racks to remove contaminants from the wastewater, protecting the machinery and pumps in subsequent treatment units. A large amount of contaminants floats on the surface of the wastewater. While conventional trash racks can intercept these contaminants, they cannot clean themselves automatically and require regular cleaning by staff, thus affecting their effectiveness. Therefore, we propose a self-cleaning circulating water treatment device to address the aforementioned problems. Summary of the Invention

[0028] The advantages of this application compared to the prior art are:

[0029] 1. This application uses a fixed base to fix the support on both sides of the sewage treatment area. The two sides of the support are hung on the working end of the height adjustment device on the fixed support by hooks. The height adjustment device lowers the filter cylinder installed in the support to a suitable position in the sewage treatment area. The filter cylinder intercepts the dirt in the sewage, causing the dirt to adhere to the outer surface of the filter cylinder. The sewage has a water flow, and the generated water flow drives the waterwheel to rotate. The waterwheel drives the blades to rotate along the filter cylinder through the first rotating shaft. The first brush set on the inner side of the blades is in contact with the outer wall of the filter cylinder. When the blades rotate, the brushes clean the dirt on the outside of the filter cylinder in a circular manner. The second rotating shaft is connected to the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the second rotating shaft. The second rotating shaft drives the spiral blade to rotate. The second brush set on the radial surface of the spiral blade cleans the dirt on the inner wall of the filter cylinder. The cleaned dirt is transported to the collection chamber through the spiral blades and blades set inside and outside, which achieves the effect of self-cleaning and circulating cleaning of dirt in the sewage.

[0030] 2. This application allows wastewater to pass through the filter cylinder via perforations. As the wastewater passes through the filter cylinder, debris is intercepted by the filter screens installed on the inner and outer walls of the filter cylinder, causing the debris in the wastewater to adhere to the filter cylinder. Several connecting rods can fix the shape of the blades, preventing the blades from changing shape when rotating outside the filter cylinder, thus affecting the normal rotation of the blades and ensuring that the blades rotate stably along the outside of the filter cylinder.

[0031] 3. This application uses the cooperation of a servo motor, a drive gear, a driven gear, and a synchronous chain to rotate the first shaft. When the flow rate of the sewage is low and cannot drive the waterwheel to rotate, the servo motor can drive the drive gear to rotate. The drive gear drives the driven gear to rotate through the synchronous chain, and the driven gear drives the first shaft and the second shaft to rotate, while simultaneously driving the blades and the spiral blades to rotate. The support and filter cartridge are floated in the sewage by the airbag. When the water level of the sewage rises or falls, the filter cartridge can be automatically adjusted to a suitable position with the assistance of the airbag to adapt to different water flow conditions.

[0032] 4. This application utilizes a tilting plate in the collection chamber to open and close the discharge port. When the collection chamber rises to the water surface, the operator tilts the plate and opens the discharge port to discharge the waste inside. The waste can be collected using a garbage bin or other container for further processing. After collection, the discharge port is closed using the tilting plate and secured with bolts. Several drainage holes at the bottom of the collection chamber filter excess wastewater, preventing wastewater from overflowing during cleaning and achieving solid-liquid separation of the discharged wastewater. Furthermore, the working end of a linear slide table drives the lifting plate to move up or down, allowing the filter cylinder and collection chamber to rise or fall simultaneously, facilitating the lifting and lowering of the water treatment device.

Detailed Implementation

[0046] To further understand the features, technical means, and specific objectives and functions achieved by this application, the following detailed description of this application is provided in conjunction with the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 12 As shown, this application provides:

[0048] A self-cleaning circulating water treatment device includes a fixed base 1, a height adjustment device 2, a support 3, a filter cartridge 4, a collection chamber 5, a waterwheel 6, and blades 7.

[0049] The fixing base 1 has a pair and is mirror-arranged on both sides of the wastewater treatment area;

[0050] The number of height adjustment devices 2 is the same as the number of fixed bases 1, and they are arranged on the fixed bases 1 in a one-to-one correspondence;

[0051] The bracket 3 is horizontally positioned between two fixed seats 1, and the top two ends of the bracket 3 are detachably connected to the working end of the height adjustment device 2 via a hanging ring device 39.

[0052] The filter cylinder 4 is horizontally mounted on the support 3, and the filter cylinder 4 has openings at both ends;

[0053] The collection chamber 5 is located at one end of the filter cylinder 4. The collection chamber 5 is provided with an inlet sleeve 8 that fits one end of the filter cylinder 4. The inner wall of the inlet sleeve 8 is provided with several connecting plates that are equidistantly distributed along the circumference of the inlet sleeve 8. Each connecting plate is fixedly connected to the outside of the filter cylinder 4. The outside of the collection chamber 5 is fixedly mounted on the bracket 3.

[0054] The blades 7 are threaded and are arranged around the outside of the filter cylinder 4;

[0055] The waterwheel 6 is located at the end of the filter cylinder 4 away from the collection chamber 5. The center of the waterwheel 6 is provided with a first rotating shaft coaxial with the filter cylinder 4. The first rotating shaft is connected to one end of the blade 7 through a connecting wheel. One end of the first rotating shaft extends into the interior of the filter cylinder 4. The other end of the filter cylinder 4 is connected to the first rotating shaft through a first bushing 11. The other end of the first rotating shaft is connected to the frame on the support 3.

[0056] Based on the above embodiments, the technical problem this application aims to solve is how to automatically and cyclically clean the wastewater in the sewage treatment area. To this end, this application pre-fixes the fixed base 1 on both sides of the sewage treatment area, and hangs the two sides of the support 3 on the working ends of the height adjustment device 2 on the fixed support 3 via the hanging ring device 39. The height adjustment device 2 lowers the filter cylinder 4 installed inside the support 3 to a suitable position in the sewage treatment area. The filter cylinder 4 intercepts the wastewater, causing the wastewater to adhere to the outer surface of the filter cylinder 4. The sewage has a water flow, which drives the waterwheel 6 to rotate. The waterwheel 6 drives the blades 7 to rotate along the filter cylinder via the first rotating shaft. The blades 7 scrape the wastewater adhering to the outside of the filter cylinder along the axis of the filter cylinder 4 into the collection chamber 5, achieving the effect of self-cleaning and cyclically cleaning the wastewater. The wastewater inside the collection chamber 5 is then transported to the outside for centralized treatment via a conveying device.

[0057] Further:

[0058] The filter cylinder 4 has several perforations 12 arranged in a matrix, and both the inner and outer walls of the filter cylinder 4 are equipped with dirt-blocking nets 13.

[0059] Based on the above embodiments, the technical problem this application aims to solve is how to intercept contaminants in sewage through the filter cylinder 4. To this end, this application utilizes the perforations 12 distributed on the filter cylinder 4 to allow sewage to pass through the filter cylinder 4. Simultaneously, as the sewage passes through the filter cylinder 4, contaminants are intercepted by the dirt-blocking nets 13 installed on the inner and outer walls of the filter cylinder 4, thereby causing the contaminants in the sewage to adhere to the filter cylinder 4.

[0060] Further:

[0061] The filter cylinder 4 has several connecting rods 14 that are equidistantly distributed along the circumference of the filter cylinder. The blades 7 are fixedly mounted on all the connecting rods 14. The axis of the connecting rods 14 is parallel to the axis of the filter cylinder 4. The connecting rods 14 are connected to the first rotating shaft through connecting wheels.

[0062] Based on the above embodiments, the technical problem this application aims to solve is how to make the blade 7 rotate stably along the outside of the filter cylinder 4. To this end, this application uses several connecting rods 14 to fix the shape of the blade 7, preventing the blade 7 from changing shape when rotating outside the filter cylinder 4, thereby affecting the normal rotation of the blade 7.

[0063] Further:

[0064] There is a gap between the inner side of the blade 7 and the outer side of the filter cylinder 4. A first brush 15 is provided on the inner side of the blade 7, and the working end of the first brush 15 is fitted to the outer side of the filter cylinder 4.

[0065] Based on the above embodiments, the technical problem this application aims to solve is how to further clean the dirt on the outer wall of the filter cylinder 4. To this end, this application uses a first brush 15 provided on the inner side of the blade 7 to adhere to the outer wall of the filter cylinder 4. When the blade 7 rotates, the brush cleans the dirt on the outside of the filter cylinder 4 in a circumferential manner, and the cleaned dirt is transported to the collection chamber 5 through the blade 7.

[0066] Further:

[0067] A second rotating shaft 16 is horizontally arranged at the center of the filter cylinder 4. One end of the second rotating shaft 16 is fixedly connected to the end of the first rotating shaft. The other end of the second rotating shaft 16 extends to the end of the filter cylinder 4 away from the waterwheel 6. A second bushing 17 is provided at the end of the filter cylinder 4 away from the waterwheel 6. The end of the second rotating shaft 16 away from the first rotating shaft is axially connected to the second bushing 17. Spiral blades 18 are distributed along the length of the second rotating shaft 16 on the outside. The radial surface of the spiral blades 18 has a gap with the inner wall of the filter cylinder 4. A second brush 19 is provided on the radial surface of the spiral blades 18. The working end of the second brush 19 is fitted to the inner wall of the filter cylinder 4.

[0068] Based on the above embodiments, the technical problem this application aims to solve is how to collect and process the dirt inside the filter cylinder 4. To this end, this application connects a second rotating shaft 16 to a first rotating shaft. The rotation of the first rotating shaft simultaneously drives the rotation of the second rotating shaft 16, which in turn drives the rotation of the spiral blade 18. The second brush 19, arranged on the radial surface of the spiral blade 18, cleans the dirt on the inner wall of the filter cylinder 4, and the cleaned dirt is then transported to the collection chamber 5 through the spiral blade 18.

[0069] Further:

[0070] A servo motor 20 is provided on the top of the bracket 3 near the waterwheel 6. The output end of the servo motor 20 is provided with a vertically arranged active tooth 21. A driven tooth 22 is coaxially arranged on the end of the first rotating shaft near the active wheel. The active tooth 21 and the driven tooth 22 are connected by a synchronous chain 23.

[0071] Based on the above embodiments, the technical problem this application aims to solve is how to drive the first rotating shaft and the second rotating shaft 16 to rotate when the flow rate of the sewage is insufficient to rotate the waterwheel 6. To this end, this application uses the cooperation of a servo motor 20, a drive gear 21, a driven gear 22, and a synchronous chain 23 to rotate the first rotating shaft. Specifically, when the flow rate of the sewage is low and insufficient to drive the waterwheel 6 to rotate, the servo motor 20 can drive the drive gear 21 to rotate. The drive gear 21 drives the driven gear 22 to rotate via the synchronous chain 23. The driven gear 22 drives the first rotating shaft and the second rotating shaft 16 to rotate, while simultaneously driving the blade 7 and the spiral blade 18 to rotate.

[0072] Further:

[0073] Airbags 24 are connected to both ends of the bracket 3, and there are 4 airbags 24 in total.

[0074] Based on the above embodiments, the technical problem this application aims to solve is how to automatically adjust the support 3 and the filter cylinder 4 to a suitable position within the sewage. To this end, this application utilizes the buoyancy generated by the airbag 24 to float the support 3 and the filter cylinder 4 within the sewage. When the sewage level rises or falls, the airbag 24 assists in automatically adjusting the support 3 and the filter cylinder 4 to a suitable position.

[0075] Further:

[0076] The lower end of the collection chamber 5 is inclined, and a discharge port is formed at the downward inclined end of the collection chamber 5. A flip plate 26 that can be flipped upward is provided at the discharge port. The flip plate 26 matches the shape of the discharge port. A first connecting plate 27 is provided in the middle of the flip plate 26. A second connecting plate 28 corresponding to the first connecting plate 27 is provided at the bottom of the collection chamber 5. The first connecting plate 27 and the second connecting plate 28 are detachably connected by bolts.

[0077] Based on the above embodiments, the technical problem this application aims to solve is how to clean the waste inside the collection chamber 5. To this end, this application uses a flip plate 26 of the collection chamber 5 to open and close the discharge port of the collection chamber 5. When the collection chamber 5 rises to the water surface, the operator flips the flip plate 26 and opens the discharge port to discharge the waste inside the collection chamber 5. The operator can then collect the waste through a garbage bin or other container for subsequent processing. After collection is complete, the discharge port is closed by flipping the plate 26 and secured with bolts.

[0078] Further:

[0079] The bottom of the collection chamber 5 is provided with several matrix-distributed drainage holes 29.

[0080] Based on the above embodiments, the technical problem this application aims to solve is how to avoid the discharge of wastewater while cleaning the collection chamber 5. To this end, this application uses several drainage holes 29 opened at the bottom of the collection chamber 5 to filter excess wastewater in the collection chamber 5, thus preventing wastewater from being discharged during cleaning.

[0081] Further:

[0082] The height adjustment device 2 includes a linear slide, a limit rod 31, and a lifting plate 32;

[0083] The linear slide is vertically mounted on the fixed base 1;

[0084] The lifting plate 32 is horizontally positioned at the working end of the linear slide, and the hanging ring device 39 is detachably installed at the bottom of the lifting plate 32.

[0085] The limiting light rods 31 are a pair and symmetrically arranged on both sides of the fixed base 1. Both limiting light rods 31 are parallel to the linear slide table. The lifting plate 32 is provided with a limiting sleeve 33 that can slide on each limiting light rod 31.

[0086] Based on the above embodiments, the technical problem this application aims to solve is how to adjust the height of the support 3, filter cylinder 4, and collection chamber 5. To this end, this application drives the lifting plate 32 upward or downward via the working end of a linear slide table. The lifting plate 32 is connected to the hanging ring device 39, allowing the filter cylinder 4 and collection chamber 5 to rise or fall simultaneously. The cooperation of the limiting light rod 31 and the limiting sliding sleeve 33 ensures greater stability of the lifting plate 32 during lifting.

[0087] Further:

[0088] The hanging ring device 39 includes a first steel rope 34, a second steel rope 35, a third steel rope 36, and a hook 38;

[0089] One end of the first steel rope 34 is provided with a limiting sleeve 2 37, and the bottom of the lifting plate 32 is provided with a hook 38 that cooperates with and connects to the limiting sleeve 2 37.

[0090] The second steel rope 35 and the third steel rope 36 are respectively located at the end of the first steel rope 34 away from the limiting sleeve 37. The ends of the second steel rope 35 and the third steel rope 36 away from the first steel rope 34 are respectively fixedly connected to the two sides of the bracket 3. The second steel rope 35 and the third steel rope 36 are arranged in an isosceles triangle.

[0091] Based on the above embodiments, the technical problem this application aims to solve is how to stably raise and lower the support 3 using the hanging ring device 39. To this end, this application uses a limiting sleeve 37 on the first steel rope 34 to connect with a hook 38 at the bottom of the lifting plate 32, and connects the second steel rope 35 and the third steel rope 36 to both sides of the support 3 respectively, so that the second steel rope 35 and the third steel rope 36 are arranged in a triangular pattern, thereby making the support 3 more stable during the raising and lowering process.

[0092] This application uses a fixed base 1 to fix the support 3 on both sides of the sewage treatment area. The support 3 is hung on both sides of the fixed support 3 by limiting sliding sleeves 37 at the working ends of the height adjustment device 2. The height adjustment device 2 lowers the filter cylinder 4 inside the support 3 to a suitable position in the sewage treatment area and stops it. The filter cylinder 4 intercepts the dirt in the sewage and makes the dirt adhere to the outer surface of the filter cylinder 4. The sewage has a water flow, and the water flow drives the waterwheel 6 to rotate. The waterwheel 6 drives the blades 7 and the spiral blades 18 to rotate along the filter barrel through the first rotating shaft and the second rotating shaft 16. The blades 7 and the spiral blades 18 scrape the dirt attached inside and outside the filter barrel along the axis of the filter cylinder 4 into the collection chamber 5, which achieves the effect of self-cleaning and circulating cleaning of dirt in the sewage. The dirt inside the collection chamber 5 is transported to the outside for centralized treatment by the conveying device. This solves the technical problem of how to automatically and cyclically clean the dirt in the sewage treatment area.
