Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of water filtration equipment, specifically a greywater reuse device. Background Technology
[0002] Greywater reuse refers to the technical measures for reusing wastewater or rainwater generated in production and daily life after a series of treatment processes to meet specific water quality standards. This concept aims to maximize the utilization of water resources and reduce the demand for fresh water. With water resources becoming increasingly scarce and under increasing pressure, greywater reuse can alleviate this pressure while reducing water pollution and environmental impact. The application of greywater reuse is now very widespread; therefore, there is a particular need for greywater reuse treatment equipment.
[0003] When wastewater is injected into the treatment equipment, a filter screen is first used to filter out solid impurities in the wastewater. However, solid impurities accumulate on the surface of the filter screen, causing it to become clogged. Secondly, when wastewater is filtered directly, the fine impurities contained in the wastewater adhere to the treatment mechanism, resulting in a decrease in wastewater filtration efficiency. Therefore, a structure that facilitates the processing of the filter screen is needed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a greywater reuse device. Its main advantages are: a filter screen inside the filter tank filters solid impurities; an activated carbon filter further filters chemicals in the water flow to meet greywater reuse standards, and the filtered water is discharged from the bottom of the filter tank for further processing; the filter tank is designed to be flip-up, and magnetic structures are installed at the inlet and outlet to attract the inlet and outlet structures, allowing the device to automatically attract the inlet and outlet structures after flipping; a baffle is installed on one side of the inlet, and the outlet structure is configured as... The movable structure allows the inlet to move to the bottom by flipping the filter bucket, and the drain head to move by the baffle, thus stopping the drainage into the drain pipe. At the same time, the drain pipe and the inlet head are automatically magnetically connected, and cleaning water is introduced into the inlet head to clean the inlet head and water pipe, while simultaneously performing a reverse cleaning of the filter bucket. This allows impurities and chemicals to be discharged from the inlet to the water collection bucket at the bottom for collection, thus completing the cleaning of the filter bucket. After cleaning, the device is reset by flipping it over, and the inlet and outlet heads are automatically attracted to both ends of the filter bucket by the magnetic structure for subsequent use, making operation convenient.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] A greywater recycling device includes a base plate, with support plates fixedly mounted on both sides of the upper part of the base plate. A filter barrel pivot hole is formed through the side of each support plate. A filter barrel pivot rod is rotatably connected inside the pivot hole on both sides. A filter barrel is fixedly mounted between the two pivot rods. A water inlet is formed at the top of the filter barrel, and a drain hole is formed at the bottom. Magnetic rings are fixedly mounted around the water inlet and drain holes. A baffle is fixedly mounted on one side of the water inlet.

[0009] Furthermore, a water receiving bucket is fixedly provided on the upper part of the base plate, and a water receiving bucket pipe is fixedly provided on one side of the water receiving bucket, which is connected to and passes through the support plate on one side. A water valve is fixedly provided at the end of the water supply pipe, the drain pipe, and the water receiving bucket pipe, which is connected to them.
[0010] Compared with the existing technology, the beneficial effects of this utility model are:
[0011] 1. Solid impurities are filtered out by setting a filter screen inside the filter bucket, and then activated carbon filter bucket is set up to filter out chemical substances in the water flow to meet the standards for reclaimed water reuse. The water is then discharged from the bottom of the filter bucket for the next step of water treatment.
[0012] 2. The filter bucket is designed to be flip-up, and magnetic structures are installed at the inlet and outlet to attract the inlet and outlet structures. After the device is flipped, it can automatically attract the inlet and outlet structures. At the same time, a baffle is installed on one side of the inlet, and the outlet structure is made movable. By flipping the filter bucket, the inlet is moved to the bottom, and the outlet is moved by the baffle to stop the drainage into the outlet pipe. At the same time, the outlet pipe is automatically magnetically connected to the inlet. Cleaning water is then introduced into the inlet to clean the inlet and outlet pipe, while the filter bucket is reverse-washed. Impurities and chemicals are discharged from the inlet to the water collection bucket at the bottom for collection, thus completing the cleaning of the filter bucket.
[0013] 3. After cleaning, the device is reset by flipping it over, and the inlet and outlet heads are automatically attracted to both ends of the filter bucket by the magnetic structure for subsequent use, so that the device can be automatically reset to perform the greywater recycling and filtration operation again.

[0028] The support plate 2 is fixedly provided with a sliding plate groove 18 inside.

[0031] Working principle:
[0032] In use, this device first introduces reclaimed water into the water supply pipe 16 and then into the magnetic inlet head 17. The magnetic inlet head 17 attracts and adheres to the magnetic ring 8 on the outer periphery of the inlet hole 6, causing the reclaimed water to flow into the filter tank 5. The filter screen 11 further filters solid impurities from the water flow. Subsequently, the activated carbon 13 inside the activated carbon tank 12 filters harmful chemicals from the water flow. Finally, the filtered water flows through the drain hole 7 and into the filter tank 5. Some of the magnetic rings 8 attract water into the magnetic drain head 22, and the water is then discharged through the drain pipe 26 to complete the greywater reuse process. After a certain number of uses, the device needs to be cleaned. At this time, the servo motor 10 is controlled to drive the filter barrel shaft 4 to rotate, thereby causing the filter barrel 11 to flip. Furthermore, the baffle 9 moves to the bottom, pushing the sliding plate 19 to move the magnetic drain head 22 to one side, so that the water inlet 6 is no longer attracted to the magnetic drain head 22, and the water flows out through the drain pipe 26. Simultaneously, the magnetic ring 8 on the outer periphery of the drain hole 7 attracts and adheres to the magnetic water inlet head 17, further introducing cleaning water containing cleaning substances into the water supply pipe 16 to clean the water supply pipe and the magnetic water inlet head 17 to a certain extent. This water can also be introduced into the filter tank 5, where it further filters through the activated carbon 13 to remove harmful substances. The cleaning water then flows through the filter screen 11 to wash away any solid impurities adhering to it. Finally, the cleaning water carrying impurities is discharged through the water inlet 6. The water is collected in the receiving bucket 27. After cleaning, the filter bucket 5 is flipped over again. Since the magnetic drain head 22 is supported by the spring support plate 25 and moves upward, the filter bucket 5 can be attracted by the magnetic ring 8 on the outer periphery of the drain hole 7 during the flipping process. The magnetic ring 8 on the outer periphery of the drain hole 7 further drives the sliding plate 20 to slide and reset. At the same time, the magnetic ring 8 on the outer periphery of the water inlet hole 6 automatically attracts the magnetic water inlet head 17, so that the device can automatically reset and perform the greywater recycling and filtration operation again.
