Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an environmentally friendly wastewater treatment device. Background Technology

[0002] With the rapid development of industrialization and urbanization, the amount of sewage discharged is increasing day by day, causing serious pollution to the environment. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or for reuse.

[0003] Patent application (publication number: CN216825009U) discloses an environmentally friendly wastewater treatment device, including a diversion component, a filter component, and a filter box. The filter box has an open top, the diversion component is engaged with the open end of the filter box, and the filter component is plugged into the interior of the filter box. A hollow rubber ring between the second filter screen and the support frame provides secondary buffering against the impact of wastewater, effectively weakening the impact and reducing damage to the first and second filter screens, extending their service life, and thus reducing the number of filter components used in wastewater filtration, which is beneficial to environmental protection.

[0004] The aforementioned application aims to extend the service life of the filter screen by reducing the impact of sewage. However, since the filter screen cannot be effectively cleaned, dirt accumulates on its surface after prolonged use, eventually causing corrosion. Therefore, simply reducing the impact of sewage to extend the service life of the filter screen is far from sufficient. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an environmentally friendly wastewater treatment device that solves the problem of ineffective cleaning of the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly wastewater treatment device, comprising:

[0016] Preferred options also include:

[0017] A loading trough is fixedly connected to the bottom end of the support frame. A backflushing device is fixedly installed on one side of the loading trough. A partition plate one is fixedly connected to the inner wall of the loading trough, and a partition plate two is fixedly connected to the inner wall of the loading trough. The height of the partition plate two is less than that of the partition plate one.

[0018] Preferably, the water inlet mechanism further includes:

[0019] A slider, the surface of which is fixedly connected with an internal threaded sleeve, and the lead screw is threadedly connected to the internal threaded sleeve.

[0020] Preferably, the teeth on the surface of the rack are arranged symmetrically on both sides, a movable plate is movably installed inside the fixed base, and the surface of the movable plate is fixedly connected with protruding teeth that can mesh with the teeth on the surface of the rack. A pull ring is fixedly connected to one end of the rack.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This environmentally friendly wastewater treatment device uses a diversion plate to divert and buffer wastewater as it enters the feed tank, weakening the impact of the water flow. A gear-driven rack adjusts the angle of the blades, thereby adjusting the angle at which the water impacts the filter screen, further reducing the impact. When the blades are fully closed, they create an interception effect, allowing wastewater in the feed tank to be discharged from the lowest point (where it is not blocked by the blades), increasing the impact force. A drive mechanism facilitates the horizontal movement of the feed tank, allowing water discharged from the lowest point to impact the surface of the filter screen, effectively washing away the trapped debris. Combined with a backwashing device, this effectively cleans the debris from the filter screen. Furthermore, the inclined shape of the filter screen facilitates the sliding of debris, thus extending its service life. Attached Figure Description

[0044] Example

[0045] Please see Figure 1-5 This utility model provides the following technical solution: an environmentally friendly wastewater treatment device, comprising:

[0046] Support frame 1;

[0047] Water inlet mechanism 2; slidably mounted on the surface of support frame 1, water inlet mechanism 2 includes:

[0048] Water supply tank 201, with flange 202 fixedly connected to its surface;

[0049] Diverter plate 203 is fixedly connected to the inner wall of water supply tank 201;

[0050] A rotating shaft 204 is rotatably connected to a water supply tank 201. One end of the rotating shaft 204 located inside the water supply tank 201 is fixedly connected to a blade 205, and another end of the rotating shaft 204 is fixedly connected to a gear 206.

[0051] The fixed base 207 has a rack 208 slidably mounted inside it, and the rack 208 meshes with the gear 206;

[0052] Filter screen 5;

[0053] Drive mechanism 4; Drive mechanism 4 includes:

[0054] Servo motor 401, with lead screw 402 fixedly connected to the output end of servo motor 401.

[0055] The present invention provides a technical solution in which the diversion plate 203 can divert and buffer sewage when it enters the water supply tank 201, weakening the impact force of the water flow. The angle of the blade 205 can be adjusted by the gear 206 driven by the rack 208, thereby adjusting the angle of the water flow impacting the filter screen 5, which helps to further weaken the impact force. When the blade 205 is fully closed, it can form an interception effect, and the sewage in the water supply tank 201 can be discharged from the lowest point of the water supply tank 201 (this position is not blocked by the blade 205), which can increase the impact force. The drive mechanism 4 can help to move the water supply tank 201 horizontally, so that the water discharged from the lowest point of the water supply tank 201 can impact the surface of the filter screen 5, which helps to wash off the dirt intercepted by the filter screen 5. With the backwashing device 7, the dirt on the filter screen 5 can be effectively cleaned. At the same time, the filter screen 5 is inclined, which helps the dirt to slide off, thereby improving the service life of the filter screen 5.

[0056] Furthermore, it also includes:

[0057] The loading trough 6 is fixedly connected to the bottom end of the support frame 1. A backflushing device 7 is fixedly installed on one side of the loading trough 6. A partition 601 is fixedly connected to the inner wall of the loading trough 6. A partition 602 is fixedly connected to the inner wall of the loading trough 6. The height of the partition 602 is less than that of the partition 601.

[0058] Specifically, partition 601 divides the loading tank 6 into two parts. The left part can store the sewage filtered by the filter screen 5 so that the water pump 701 can extract it. The right part can store the dirt that falls off the filter screen 5. Since the height of partition 602 is less than that of partition 601, the sewage in the left part can overflow through partition 602 and be discharged.

[0059] Furthermore, the water inlet mechanism 2 also includes:

[0060] The slider 209 has an internal threaded sleeve 210 fixedly connected to its surface, and the lead screw 402 is threadedly connected to the internal threaded sleeve 210.

[0061] Specifically, the slider 209 improves the stability of the translation of the water inlet mechanism 2, and the lead screw 402 is driven by the servo motor 401 to rotate, thereby driving the internal thread sleeve 210, slider 209, water tank 201 and other components to move horizontally.

[0062] Furthermore, the teeth on the surface of the rack 208 are arranged symmetrically on both sides. A movable plate 211 is movably installed inside the fixed base 207. A protruding tooth 212 is fixedly connected to the surface of the movable plate 211. The protruding tooth 212 can mesh with the teeth on the surface of the rack 208. A pull ring 213 is fixedly connected to one end of the rack 208.

[0063] Specifically, by pressing, the protruding teeth 212 of the movable plate 211 can disengage from the teeth of the toothed rod 208, and then the pull ring 213 can drive the toothed rod 208 to slide within the fixed seat 207. The angle of the leaf plate 205 can be adjusted by rotating the drive gear 206. When it is necessary to fix it, the protruding teeth 212 of the movable plate 211 can be engaged again into the teeth of the toothed rod 208, thus fixing the toothed rod 208.

[0064] Furthermore, both the water inlet mechanism 2 and the filter screen 5 are inclined.

[0065] Specifically, the inclined shape of the water inlet mechanism 2 facilitates the concentrated discharge of sewage from the lowest point, enhancing its impact force and helping to flush away dirt on the filter screen 5. The inclined shape of the filter screen 5 also facilitates the automatic sliding of dirt, further improving cleaning efficiency.

[0066] Furthermore, a support rod 8 is fixedly connected to the side of the loading slot 6, and a bolt 3 is inserted inside the support rod 8. One end of the bolt 3 is threadedly connected to the filter screen 5.

[0067] Specifically, the filter screen 5 can be fixed by bolt 3, and the filter screen 5 can be easily replaced after removing bolt 3.

[0068] Furthermore, the recoil device 7 includes:

[0069] Water pump 701; the input end of water pump 701 is fixedly connected to a water pumping pipe 702, and the output end of water pumping pipe 702 is fixedly connected to a water guide pipe 703;

[0070] Spray nozzles 704 are installed on the surface of water guide pipes 703, arranged in a horizontal array, facing the filter screen 5.

[0071] Specifically, the water pump 701 draws water from the loading tank 6 through the water pumping pipe 702 and pumps it into the water guide pipe 703, so that it can be sprayed out from the nozzle 704. Since the nozzle 704 is oriented towards the filter screen 5, it can impact the filter screen 5, which can help remove dirt from the surface of the filter screen 5.

[0072] All electrical equipment in this device is powered by an external power source and is controlled to operate and shut down via a matching control switch.

[0073] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
