Technical Field
[0001] This application relates to the field of filtration device technology, and more specifically, to rotary wastewater filtration devices. Background Technology
[0002] Wastewater separation is a crucial part of wastewater treatment, and in most existing wastewater treatment processes, wastewater separation equipment is used to treat the wastewater.
[0003] Patent CN221181932U discloses a horizontal wastewater separation device. This utility model provides a horizontal wastewater separation device, including a filtration device, a spraying system, and a wastewater tank with an inlet and an outlet. The filtration device is installed inclined inside the wastewater tank along its own axis, with the end of the filtration device near the inlet higher than the end near the outlet. The filtration device can rotate around its own rotation center. The inlet is connected to the filtration device. The end of the wastewater tank away from the inlet can be opened to discharge sludge. The spraying system is located at the top of the wastewater tank and above the filtration device. Wastewater flows out from the outlet. Compared with the prior art, the sewage outlet and sludge outlet do not interfere with each other, sludge does not affect wastewater discharge, the separation effect of sewage and sludge is increased, the quality of wastewater treatment is improved, wastewater can be collected quickly, preparing for the next step of wastewater purification in industry, and improving work efficiency.
[0004] Although the existing technical solutions mentioned above achieve the effect of cleaning the filter cartridge by setting up a spraying system so that the sludge slides down or falls to the bottom of the filter device under the action of gravity and is discharged from the sewage tank along the inclined direction, the existing filter cartridge has densely packed filter holes, and its internal friction is relatively large. As it is not a smooth surface, it is difficult for impurities to be completely discharged from the filter cartridge by the inclined gravity. Over time, the filter holes at the bottom of the filter cartridge will become more and more clogged and cannot be disassembled for cleaning.
[0005] In view of this, we propose a rotary wastewater filtration device. Utility Model Content

[0017] 3. Beneficial effects
[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0019] (1) This application uses a high-pressure water pump connected to a municipal water pipe at one end to transport water upwards through a water supply pipe, then through a distribution pipe, and finally through a spray nozzle to perform high-pressure rinsing on the top of the filter cylinder. The high-pressure rinsing washes away impurities in the filter holes, causing them to fall into the conical hopper.

Detailed Implementation
[0026] The present application will be further described in detail below with reference to the accompanying drawings.
[0027] Example 1
[0028] Please see Figure 1-4An embodiment of this utility model provides a rotary sewage filtration device, including a workbench 110 and a collection component 140. The top of the workbench 110 is provided with an outer cover 112, and a concave support 111 is fixedly provided on the workbench 110. A filter cylinder 150 is rotatably arranged inside the workbench 110. A drive component is provided on the side of the concave support 111 near the filter cylinder 150. A spray component 130 is provided on one side of the workbench 110. The spray component 130 includes a water supply pipe 133. One end of the water supply pipe 133 is connected to a diversion pipe 131, and spray heads 132 are evenly arranged below the diversion pipe 131. The spray heads 132 are located above the cone hopper 144. The other end of the water supply pipe 133 is connected downward to a high-pressure water pump 134. One end of the collection component 140 is disposed inside the filter cartridge 150 without contact. The collection component 140 includes a mounting plate 143, which is mounted on one side of the outer cover 112 by screws. A collection tube 141 is inserted inside the mounting plate 143, and a partial water permeable hole is provided at the bottom end of the collection tube 141. A conical hopper 144 is welded above the end of the collection tube 141 that extends into the filter cartridge 150. A threaded cap 142 is threadedly installed at the end of the collection tube 141 away from the conical hopper 144, and a sealing ring is provided inside the threaded cap 142. The collection tube 141 has a downward trend from the inside of the filter cartridge 150 to the outside. One end of the high-pressure water pump 134 is connected to a municipal water pipe, which delivers water upward through the water supply pipe 133, through the distribution pipe 131, and finally through the spray head 132 to perform high-pressure rinsing on the top of the filter cartridge 150. The high-pressure rinsing washes away impurities in the filter holes, causing them to fall into the conical hopper 144. The filter cartridge 150 rotates and rinses once, and all the intercepted impurities and rinsing wastewater enter the conical hopper 144. The permeable holes filter out the water, and then the inclined and smooth-internal collection pipe 141 allows impurities to be discharged from the threaded cover 142, avoiding the problem of impurities not being fully discharged when directly passing through the filter cartridge 150 in the existing technology. Furthermore, the entire collection assembly 140 can be disassembled for internal cleaning.
[0029] Furthermore, a water inlet pipe 115 is fixedly installed on the concave bracket 111, with one end of the water inlet pipe 115 inserted into the filter cylinder 150 without contact. A water tank 113 is opened inside the workbench 110, and a drain pipe 114 is provided on one side of the workbench 110. Wastewater enters through the water inlet pipe 115, and the rotation of the filter cylinder 150 does not affect the water inlet pipe 115. The wastewater filtered by the rotation enters the water tank 113 and is finally discharged from the drain pipe 114 to enter the next process.
[0030] Furthermore, the drive assembly includes a drive motor 121 fixedly mounted on a concave bracket 111, with a drive gear 122 connected to the drive end of the drive motor 121. A gear ring 120 is meshed on one side of the drive gear 122, and the gear ring 120 is fixedly mounted at the center of one side of the filter cartridge 150. Auxiliary slip rings 151 are symmetrically arranged on both sides of the filter cartridge 150. Four sets of fixing brackets 153 are arranged below the filter cartridge 150, and each fixing bracket 153 has a pulley 152 rotatably mounted inside. When the drive motor 121 starts, it drives the drive gear 122 to rotate, which in turn drives the gear ring 120 to rotate, causing the entire filter cartridge 150 to rotate. The fixing brackets 153 and pulleys 152 limit the rotational position of the filter cartridge 150 while supporting the stable rotation of the filter cartridge 150, which can reduce the pressure on the shaft of the drive motor 121 and increase the service life of the drive motor 121.
[0031] In summary, when using the rotary wastewater filtration device disclosed in this application, one end of the high-pressure water pump 134 is connected to a municipal water pipe, which transports water upward through the water supply pipe 133, through the distribution pipe 131, and finally through the spray head 132 to perform high-pressure rinsing on the top of the filter cylinder 150. The high-pressure rinsing washes away impurities in the filter holes, causing them to fall into the conical hopper 144. The filter cylinder 150 rotates and rinses once, and all the intercepted impurities and rinsing wastewater enter the conical hopper 144. The permeable holes filter out the water, and the collection pipe 141 is inclined and has a smooth interior, allowing impurities to be discharged from the threaded cover 142, avoiding the problem in the prior art where impurities cannot be completely discharged directly through the filter cylinder 150. Furthermore, the entire collection assembly 140 can be disassembled for internal cleaning.
[0032] When the drive motor 121 starts, it drives the drive gear 122 to rotate. The rotation of the drive gear 122 drives the gear ring 120 to rotate, causing the entire filter cartridge 150 to rotate. The fixed frame 153 and the pulley 152 limit the rotation position of the filter cartridge 150, while bearing the stable rotation of the filter cartridge 150. This reduces the pressure on the shaft of the drive motor 121 and increases the service life of the drive motor 121.
