Description

Technical Field

[0001] This utility model relates to the field of greywater recycling technology, specifically a greywater recycling device. Background Technology

[0002] Reclaimed water, also known as recycled water, refers to wastewater or rainwater that has been properly treated to meet certain water quality standards and usage requirements, making it suitable for beneficial use. Its water quality falls between that of water supply and drainage.

[0003] In the process of recycling and reusing greywater, the collected raw water must first undergo pretreatment. The pretreatment stage mainly includes key steps such as filtration and impurity removal, aiming to remove larger suspended solids and particulate impurities from the water. Since greywater primarily originates from domestic wastewater, industrial drainage, and rainwater, its composition is complex, often containing various impurities such as fibers, hair, silt, and organic matter. During filtration and impurity removal, these impurities easily adhere to the surface of filter elements such as filter screens and media, causing blockages, increasing filtration resistance, and consequently reducing overall filtration efficiency.

[0014] Beneficial effects

[0015] This invention provides a greywater recycling device. Compared with the prior art, it has the following advantages:

[0016] (1) A greywater recycling device, by setting up a scraping component, can effectively remove impurities attached to the outside of the filter component, ensuring that the filter component can continuously maintain stable filtration performance. In addition, the internal structure of the filter component has been optimized to enable it to have a backwashing function. When the filter screen needs to be cleaned, the outlet at the top of the delivery pump can be connected to an external water source, and then the flow direction of the delivery pump can be adjusted to force external water into the filter screen body through the connecting pipe for high-pressure rinsing. This process can thoroughly remove impurities clogging the filter holes, thereby achieving efficient cleaning of the filter screen body, extending its service life, and ensuring long-term stable operation of the system.

[0017] (2) A greywater recycling device, which uses a purification component to further purify filtered water transported through a hose. When the filtered water enters the cavity of the activated carbon adsorption filter media through the hose, the gravity and inertia generated during its descent drive the sliding part and the limiting part to move downwards. Subsequently, under the action of the return spring, they rebound to their original positions. The reciprocating motion generated in this process not only buffers the impact of the water flow and protects the activated carbon adsorption filter media, but also enhances the contact between the filtered water and the activated carbon adsorption filter media through continuous up-and-down vibration, accelerates the reaction speed, and thus improves the impurity adsorption effect and the overall water treatment efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-3 A greywater recycling device includes a treatment tank 1, which has a filter chamber 2 and a dirt removal chamber 3. A sewage discharge valve 4 and a recovery valve 5 are threadedly connected to both sides of the treatment tank 1. The interface on the side of the sewage discharge valve 4 is connected to the interior of the filter chamber 2. The structure on the side of the recovery valve 5 is connected to the interior of the dirt removal chamber 3. A scraping assembly 8 is provided in the filter chamber 2. The scraping assembly 8 includes a drive motor 801 fixedly installed on the top of the treatment tank 1. The power shaft of the drive motor 801 extends into the filter chamber 2 and is fixedly connected to a threaded drive component 802 through a bearing. A gear ring 803 is meshed with the side of the threaded drive component 802. The top of the gear ring 803 is rotatably connected to the inner wall of the filter chamber 2. A rotating seat 804 is fixedly connected to the inner side of the gear ring 803 through a scraper 805. The rotating seat 804 is rotatably connected to the inner bottom wall of the filter chamber 2.

[0027] The filter chamber 2 is provided with a filter assembly 7. The filter assembly 7 includes a connector 701 that is threadedly connected to the top of the processing box 1. The connector 701 has anti-slip protrusions 702 on its outside. The bottom of the connector 701 is fixedly connected to a filter screen body 703. The outside of the filter screen body 703 is in contact with the scraper 805.

[0028] A delivery pump 704 is fixedly installed inside the connector 701. A connector 11 is fixedly connected to the top connection port of the delivery pump 704, and a water pumping pipe 705 is fixedly connected to the bottom connection port of the delivery pump 704.

[0029] In this embodiment, by providing the scraping component 8, impurities attached to the outside of the filter component 7 can be effectively removed, ensuring that the filter component 7 can maintain stable filtration performance continuously. In addition, the internal structure of the filter component 7 has been optimized to give it a backwashing function, which can quickly remove impurities from the filter pores of the filter body 703 through backwashing, reducing maintenance time and improving work efficiency.

[0030] During the filtration process, impurities adhere to the outside of the filter body 703, affecting its filtration performance. Therefore, during filtration, the scraping assembly 8 is activated to scrape off the impurities attached to the outside of the filter body 703, thereby improving the filtration effect. The specific workflow is as follows: the drive motor 801 is controlled to operate, which drives the threaded drive component 802 to rotate. Since the threaded drive component 802 and the gear ring 803 are meshed, the gear ring 803 also rotates when the threaded drive component 802 rotates, thereby driving the scraper 805 to scrape off the impurities attached to the outside of the filter body 703, thus ensuring that the filter body 703 can work normally. The drive motor 801 is controlled by a PLC.

[0031] When the filter body 703 needs to be cleaned, separate the hose 10 and the connector 11, then fix the connector 11 to the external water pipe at the top, then change the delivery direction of the delivery pump 704 so that the external water source can be delivered to the filter body 703 through the delivery pump 704 and the water pipe 705, thereby quickly washing away the impurities in the filter holes of the filter body 703 through backwashing. Then open the sewage discharge valve 4 to discharge the backwashed sewage from the sewage discharge valve 4.

[0032] Example 2:

[0033] Please see Figure 2-4 This embodiment provides a technical solution based on embodiment one: a cleaning component 9 is provided in the cleaning chamber 3. The cleaning component 9 includes a limiting rod 902 fixed to the top of the processing box 1. A sliding member 904 is slidably connected to the top of the processing box 1. A limiting part 901 is provided on the outer side of the sliding member 904. The limiting part 901 and the limiting rod 902 are slidably connected. An activated carbon adsorption filter material 905 is fixedly connected to the bottom of the sliding member 904. The activated carbon adsorption filter material 905 is rectangular in shape.

[0034] A reset spring 903 is provided on the outside of the limit rod 902. The top of the reset spring 903 is fixedly connected to the limit part 901, and the bottom of the reset spring 903 is fixedly connected to the processing box 1. A damping rod is provided inside the reset spring 903.

[0035] A flexible tube 10 is provided on the top of the sliding member 904. One end of the flexible tube 10 extends into the activated carbon adsorption filter media 905, and the other end of the flexible tube 10 is fixedly connected to the connecting joint 11.

[0036] In this embodiment, the continuous treatment process of raw water is achieved through the coordinated use of the filter assembly 7, the impurity removal assembly 9, the hose 10, and the connecting joint 11. This enables the pretreatment of raw water, removing and purifying impurities. The reset spring 903 drives the purification structure composed of the limiting part 901, the sliding part 904, and the activated carbon adsorption filter media 905 to reciprocate. This not only buffers the impact of water flow on the activated carbon adsorption filter media 905, protecting it, but also enhances the contact between the filtered water and the activated carbon adsorption filter media 905 through continuous up-and-down vibration, accelerating the reaction efficiency.

[0037] During operation, the wastewater discharge valve 4 and the recovery valve 5 are closed first. Raw water is poured into the filter chamber 2 through the water inlet 6. Then, the delivery pump 704 is started. The delivery pump 704 delivers the filtered water through the water pumping pipe 705 and the hose 10 into the impurity removal component 9. When the filtered water enters the chamber of the activated carbon adsorption filter media 905 through the hose 10, the gravity and inertia generated during its fall drive the limiting part 901, the sliding part 904, and the activated carbon adsorption filter media 905 to move downward as a whole. Then, under the action of the return spring 903, it is driven to rebound and reset. The reaction is accelerated during the reciprocating process. After the filtered water and the activated carbon adsorption filter media 905 react, they fall into the impurity removal chamber 3 for storage and can flow out through the recovery valve 5. The activated carbon adsorption filter media 905 is square in shape, which can increase the contact area with the filtered water, thereby improving the purification efficiency. In addition, the activated carbon structure of the activated carbon adsorption filter media 905 is honeycomb, which can prolong the contact time when the filtered water and activated carbon come into contact, ensuring that the filtered water can be fully purified.

[0038] Please see Figure 5 This embodiment provides a technical solution based on embodiment one: a water inlet 6 is provided on the side of the treatment tank 1, and a flow control component 12 is provided on the top of the treatment tank 1 at the position corresponding to the water inlet 6. The flow control component 12 includes two round rods 1203 fixed to the top of the treatment tank 1, a fixing plate 1204 is fixedly connected to the top of the two round rods 1203, and an adjusting screw 1205 is threadedly connected to the top of the fixing plate 1204.

[0039] The bottom of the adjusting screw 1205 is provided with a baffle 1202, and the top of the baffle 1202 is provided with a sliding part 1201. The top of the sliding part 1201 is rotatably connected to the adjusting screw 1205, and the bottom of the baffle 1202 passes through the treatment box 1 and is inserted into the water inlet.

[0040] In this embodiment, when raw water is added through the water inlet 6, the flow control component 12 can control the water volume. At the same time, the baffle 1202 can block the water inlet 6 to achieve coarse filtration of large particles in the raw water. The working process is as follows: first, by turning the adjusting screw 1205, the sliding part 1201 and the baffle 1202 are driven to move downward, so that the baffle 1202 is close to the inner wall of the water inlet 6 to block the water inlet 6. This not only controls the flow rate of the raw water, but also completes the coarse filtration process of the raw water, which can effectively prevent large particles from entering the filter chamber 2.
