Description

Technical Field

[0001] This utility model relates to a circulating constructed wetland for wastewater purification, belonging to the field of constructed wetland technology. Background Technology

[0002] Constructed wetlands are artificially built and controlled wetlands similar to marshes. Wastewater and sludge are systematically distributed onto these artificially constructed wetlands. As the wastewater and sludge flow in a certain direction, the technology mainly utilizes the physical, chemical, and biological synergistic effects of soil, artificial media, plants, and microorganisms to treat the wastewater and sludge.

[0003] Chinese Patent Publication No. (CN 218811115 U) discloses a circulating constructed wetland device for wastewater purification, including a filtration module and a wetland module. The filtration module contains a first filter element and a second filter element. The first filter element includes a filter assembly and a receiving plate located in the middle of the filter assembly. The second filter element has the same structure as the first filter element, and a sterilization lamp is installed at its lower end. The filtration module and the wetland module are connected by a water pipe. Multiple sets of first and second partition plates are fixedly installed inside the wetland module, with the first and second partition plates arranged alternately. A first water passage hole is opened at the lower end of the first partition plate, and a second water passage hole is opened at the upper end of the second partition plate. Filter screens are fixedly installed inside the first and second water passage holes respectively. This invention solves the problems of severe clogging, low purification efficiency, and slow processing speed in existing constructed wetlands.

[0004] Before wastewater is discharged into constructed wetlands, a filtration and purification device is needed to filter out large-volume impurities in the wastewater. Although the aforementioned purification device can filter out sludge and other larger particles in the wastewater through the first and second filter elements, these impurities will accumulate on the receiving plate. However, during the wastewater filtration process, impurities tend to accumulate on the filter elements, causing mesh blockage. Furthermore, after prolonged use, too much debris will accumulate on the receiving plate, making it difficult to remove, replace, and clean the filter elements. This reduces the efficiency of subsequent wastewater purification and diminishes the practicality of the device.

[0005] Therefore, a circulating constructed wetland for wastewater purification is proposed. Utility Model Content

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a circulating constructed wetland for sewage purification, including a purification tank 1 and a constructed wetland body 4. A water outlet pipe 5 is connected to the rear side of the constructed wetland body 4, and a first control valve 6 is installed on the inner surface of the water outlet pipe 5. A filter assembly 3 is installed in the inner cavity of the purification tank 1, and a receiving plate 16 is fixedly installed on the inner side of the filter assembly 3. A disassembly mechanism 2 is installed in the inner cavity of the purification tank 1. The disassembly mechanism 2 includes a cover plate 201, a plug 202, a slot 203, a gear 205, a welding rod 207, an auxiliary plate 208, and a worm gear 211. The gear 205 has two front and rear... The sides are connected by toothed plates 206 through toothed meshing. An insert rod 209 is fixedly installed on the inner side of the auxiliary plate 208. The inner side of the insert rod 209 passes through the inner cavity of the through hole 210 and is inserted into the inner cavity of the insert hole 204. The left side of the top of the cover plate 201 is connected to the water inlet pipe 9. The water outlet pipe 5 can be connected to the water inlet pipe 9 through a pipe. A support plate 10 is fixedly installed on the rear side of the top of the cover plate 201. Mounting plates 11 are fixedly connected to the left and right sides of the front end of the support plate 10. The welding rod 207 is fixedly connected to the outer side of the toothed plate 206. The other end of the welding rod 207 is fixedly connected to the top of the auxiliary plate 208.

[0030] Wastewater is purified by the filter assembly 3. Sludge and impurities slide onto the surface of the receiving plate 16 and accumulate. Water discharged from the outlet pipe 5 can be reconnected to the inlet pipe 9 through the pipe for repeated purification. With the disassembly mechanism 2, the gear 205 and the toothed plate 206 mesh to move the insertion rod 209 outward, causing the insertion rod 209 to disengage from the inner cavity of the insertion hole 204, separating the cover plate 201 from the purification box 1, and removing the filter assembly 3. This facilitates the cleaning of accumulated impurities and ensures the subsequent purification effect on wastewater.

[0031] Example 2

[0032] In one embodiment, the outer surface of the worm 211 is connected to a worm wheel 212 via toothed meshing. A rotating shaft 213 is fixedly connected to the inner surface of the worm wheel 212. The lower end of the rotating shaft 213 is fixedly connected to the inner surface of the gear 205. The worm 211 is movably connected to the inner side of the mounting plate 11 via a bearing. A handwheel 12 is fixedly connected to the right side of the worm 211. A water pipe 7 is connected to the rear side of the purification box 1. The other end of the water pipe 7 is connected to the inner cavity of the artificial wetland body 4. The inner surface of the water pipe 7 is fixedly mounted... There is a second control valve 8. A slider 13 is fixedly installed on the bottom of the toothed plate 206. Slide grooves 14 are opened on both the front and rear sides of the top of the cover plate 201. The bottom of the slider 13 is slidably connected to the inner cavity of the slide groove 14. An observation window 15 is provided on the front side of the purification box 1. The observation window 15 is connected to the front side of the purification box 1 by bolt thread. A locking block 17 is fixedly installed on both the left and right sides of the filter assembly 3. A locking groove 18 is opened on both the left and right sides of the inner cavity of the purification box 1. The outer side of the locking block 17 is locked into the inner cavity of the locking groove 18.

[0033] By setting the worm gear 211 and worm wheel 212, a self-locking function can be achieved to prevent the gear 205 from rotating and causing the toothed plate 206 to move. By setting the handwheel 12, the worm gear 211 can be rotated, which serves as a transmission function. By setting the water pipe 7 and the second control valve 8, it is convenient to transport the purified water in the purification tank 1 to the artificial wetland body 4. By setting the observation window 15, the accumulation of impurities can be observed. By setting the locking block 17 and the locking groove 18, the filter assembly 3 can be easily fixed.

[0034] In operation, wastewater enters the purification tank 1 through the inlet pipe 9. As the wastewater passes through the filter assembly 3 and the receiving plate 16, it is filtered and purified by the filter assembly 3. Sludge and impurities slide onto the receiving plate 16. The second control valve 8 is opened, allowing the purified water in the purification tank 1 to flow into the artificial wetland body 4 through the water pipe 7. The first control valve 6 is opened, allowing the water in the artificial wetland body 4 to be discharged through the outlet pipe 5. The water discharged from the outlet pipe 5 can be reconnected to the inlet pipe 9 through a pipe, thus circulating the purification process. When excessive impurities are observed through the observation window 15, the handwheel 12 is turned, causing the handwheel 12 to drive the worm gear 211 to rotate. The worm gear 211 engages with the teeth... The action drives the worm gear 212 to rotate, which in turn drives the shaft 213 and gear 205 to rotate. The gear 205, through the meshing of its teeth, drives the toothed plate 206 to move outward. The toothed plate 206 drives the welding rod 207 and the auxiliary plate 208 to move outward. The auxiliary plate 208 drives the insertion rod 209 to move outward, causing the insertion rod 209 to disengage from the inner cavity of the insertion block 202. The cover plate 201 is lifted upward, causing the cover plate 201 to drive the insertion block 202 to disengage from the inner cavity of the slot 203. The filter assembly 3 is pulled upward, causing the filter assembly 3 to drive the locking block 17 to disengage from the inner cavity of the locking groove 18. The filter assembly 3 and the receiving plate 16 are moved out of the interior of the purification box 1, thus cleaning the accumulated sludge and impurities.

[0035] When cleaning is complete and installation is required, the filter assembly 3 is engaged with the inner cavity of the slot 18 via the locking block 17, causing the cover plate 201 to engage with the insert block 202 in the inner cavity of the slot 203. The handwheel 12 is rotated in the opposite direction, causing the handwheel 12 to drive the worm gear 211 to rotate. The worm gear 211 drives the worm wheel 212 to rotate through the meshing of its teeth. The worm wheel 212 drives the rotating shaft 213 and the gear 205 to rotate. The gear 205 drives the toothed plate 206 to move inward through the meshing of its teeth. The toothed plate 206 drives the welding rod 207 and the auxiliary plate 208 to move inward. The auxiliary plate 208 drives the insert rod 209 to move inward, so that the insert rod 209 passes through the inner cavity of the through hole 210 and is inserted into the inner cavity of the insert block 202, thus sealing the purification box 1 for easy use.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
