Description

Technical Field

[0001] This utility model relates to a rainwater recycling and treatment device. Background Technology

[0002] my country has relatively abundant total water resources, but they are characterized by insufficient per capita water resources and uneven spatial and temporal distribution, with more water in the south and less in the north. Therefore, reducing water waste is essential and is an important challenge for the country's sustainable development. Rainwater collection through water storage tanks is a common water-saving method in water-scarce areas.

[0003] The published patent document CN221681955U discloses a rainwater harvesting and treatment device structure, including a water storage tank for storing rainwater. A filter plate with mesh holes is installed at the upper inlet of the water storage tank. A scraping device is provided on the water storage tank, comprising a scraper, a spring, and a linear drive mechanism. The scraper is arranged along the width of the filter plate, and its length covers the width of the filter plate. The spring provides a downward pressing force to the scraper, enabling it to press against the upper surface of the filter plate. The linear drive mechanism drives the scraper to reciprocate linearly along the length of the filter plate. This invention solves the technical problem that during long-term rainwater collection, large solid impurities clog the filter screen, causing rainwater overflow and affecting the rainwater collection effect.

[0004] However, the aforementioned device does not thoroughly remove impurities from the filter plate surface. The scraper only adheres to the filter plate surface through the compression force of a spring, and some smaller and thinner impurities, such as blades, may stick to the filter plate surface and cannot be scraped off. Furthermore, the scraper cannot remove impurities inside the filter plate mesh, and the mesh will still become clogged during long-term collection, thus affecting the rainwater collection efficiency. Manual cleaning, on the other hand, increases labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a rainwater harvesting and treatment device to solve the problem in the prior art where the scraper does not completely remove impurities from the surface of the filter plate. The scraper only adheres to the filter plate surface through the pressure of a spring, and smaller, thinner impurities, such as blades, may stick to the filter plate surface and cannot be removed by the scraper. Furthermore, the scraper cannot remove impurities inside the filter plate mesh.

[0006] The technical solution of this utility model is as follows:

[0007] A rainwater harvesting and treatment device includes a water storage tank for storing rainwater. A filter plate with mesh holes is installed at the upper inlet of the water storage tank. A scraping device is provided on the water storage tank, which includes a scraper, a spring, and a linear drive mechanism. The scraper is arranged along the width direction of the filter plate, and the length of the scraper covers the width of the filter plate. The spring provides a vertically downward squeezing force to the scraper, enabling the scraper to press against the upper surface of the filter plate. The linear drive mechanism drives the scraper to reciprocate linearly along the length direction of the filter plate. The device is characterized by further including a blowing device, which includes multiple nozzles. The nozzles are located below the filter plate and spaced apart along the width direction of the filter plate. The air outlets of the nozzles face the lower surface of the filter plate, and the blowing airflow from the nozzles covers the width of the filter plate. The nozzles are connected to an air source. An upper magnet is provided on the scraper, and a corresponding lower magnet is provided on the nozzle. The nozzles and the scraper are coupled through the upper and lower magnets to achieve synchronous movement. The nozzles are located in front of the front surface of the scraper. During operation, the nozzles first blow out impurities, and then the scraper scrapes away the impurities.

[0008] The beneficial effects of this technical solution are as follows: During operation, the nozzle is connected to the air source, and the nozzle outlet faces the lower surface of the filter plate. After the air source is turned on, the nozzle sprays an upward airflow. Since there are multiple nozzles, and they are spaced apart along the width of the filter plate, the sprayed airflow can cover the width of the filter plate. After the linear drive mechanism is started, due to the coupling effect between the upper and lower magnets, the nozzle will move synchronously with the scraper. Since the nozzle is located in front of the front surface of the scraper, the nozzle can first blow up the smaller and thinner impurities adhering to the mesh and surface of the filter plate, and the scraper will then scrape away the impurities. In this way, a linkage effect of blowing first and then scraping can be formed, and the impurity removal effect can be significantly improved.

[0009] Furthermore, a water-retaining cap is provided above the air outlet of the nozzle, and the vertical projection of the water-retaining cap covers the air outlet of the nozzle.

[0010] The beneficial effects of this technical solution are as follows: Since the nozzle is located below the filter plate and the nozzle outlet faces the lower surface of the filter plate, rainwater remaining on the filter plate may flow into the nozzle when the nozzle is not in operation; the water baffle can effectively prevent rainwater from flowing into the nozzle.

[0011] Furthermore, a baffle seat is provided around the nozzle. The baffle seat includes a first baffle surface and a second baffle surface connected at a certain angle. The first baffle surface is set facing upward, and the second baffle surface extends upward from the first baffle surface. The first baffle surface is located below the lower surface of the water baffle cap.

[0012] The beneficial effects of this technical solution are as follows: due to the water baffle cap above the nozzle outlet, the upward airflow from the nozzle will be blocked by the water baffle cap; the baffle seat can guide the airflow. The airflow blocked by the water baffle cap is guided by the first and second baffle surfaces, and the second baffle surface extends upward from the first baffle surface, so the airflow direction will be upward again.

[0013] Furthermore, the baffle seat is a conical cylindrical structure with an upward opening.

[0014] The beneficial effects of this technical solution are: the baffle seat is a cone-shaped cylindrical structure with an upward opening, which allows the airflow ejected from the nozzle to cover a larger area, thus reducing the number of nozzles required.

[0015] Furthermore, a smooth coating is provided on the first and second deflector surfaces.

[0016] The beneficial effects of this technical solution are as follows: The first and second deflector surfaces are coated with a smooth coating, which can reduce the frictional resistance between the airflow and the deflector surfaces, reduce the turbulence burst and flow separation near the deflector surfaces, and make the blown airflow more uniform.

[0017] Furthermore, a rolling element is provided between the lower magnet and the filter plate.

[0018] The beneficial effects of this technical solution are as follows: The scraper is equipped with an upper magnet, and the nozzle is equipped with a corresponding lower magnet. The scraper drives the nozzle and the lower magnet to move back and forth in a straight line along the length of the filter plate through the coupling effect between the upper and lower magnets. Friction will be generated between the lower magnet and the filter plate. The setting of the rolling element can change the sliding friction between the two into roller friction, which can greatly reduce friction and reduce wear.

[0019] Furthermore, the inner wall of the water tank is equipped with a limiting slide rail, on which the lower magnet moves.

[0020] The beneficial effects of this technical solution are: the lower magnet moves on the limiting slide rail, which provides support for the lower magnet and prevents it from deviating from the track during movement; in addition, the limiting slide rail can strictly limit the movement path of the magnet, so that it can only move along a preset straight track.

[0021] Furthermore, the blowing device includes a diversion pipe, on which a diversion outlet is provided corresponding to each nozzle, and each nozzle is connected to its corresponding diversion outlet. The inlet of the diversion pipe is connected to the air source.

[0022] The beneficial effects of this technical solution are: due to the setting of the diversion pipe, the air source only needs one connecting pipe to provide airflow to multiple nozzles at the same time, reducing the use of connecting pipes. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0034] A specific embodiment of the rainwater harvesting and treatment device of this utility model is as follows: Figures 1-6 As shown, the system includes a water storage tank 1, a filter plate 2, a scraping device, and a jetting device. The filter plate 2 is installed at the upper inlet of the water storage tank 1. The filter plate 2 has mesh openings. The water storage tank 1 is made of high-density polyethylene, and the filter plate 2 is made of aluminum. The water storage tank 1 is equipped with a scraping device, which includes a scraper 3, a spring 4, and a linear drive mechanism 5. The scraper 3 is arranged along the width of the filter plate 2, and its length covers the width of the filter plate 2. The spring 4 provides a downward pressing force to the scraper 3, allowing it to press against the upper surface of the filter plate 2. Two sets of linear drive mechanisms 5 drive the scraper 3 to reciprocate linearly along the length of the filter plate 2. The jetting device includes a jetting assembly 6, an air source 7, and a diverter pipe 12. The jetting assembly includes nozzles 61, baffle seats 63, and water-blocking caps 62. There are five nozzles 61, located below the filter plate 2 and along its width. The nozzles 61 are spaced apart, with their outlets facing the lower surface of the filter plate 2, and the airflow from the nozzles 61 covering the width of the filter plate 2. A water baffle 62 is provided above the outlet of the nozzles 61, and the water baffle 62 is fixedly connected to the nozzles 61 by a support rod. The vertical projection of the water baffle 62 covers the outlet of the nozzles 61. A baffle seat 63 is provided around the nozzles 61. The baffle seat 63 is a conical cylindrical structure with an upward opening. The baffle seat 63 includes a first baffle surface and a second baffle surface connected at a certain angle. The first and second baffle surfaces are provided with a smooth coating. The first baffle surface 631 is set upward, and the second baffle surface 632 extends upward from the first baffle surface 631. The first baffle surface 631 is located below the lower surface of the water baffle 62. A diversion pipe 12 is provided with a diversion outlet corresponding to each nozzle 61. The nozzles 61 are connected to the corresponding diversion outlets, and the inlet of the diversion pipe 12 is connected to the air source 7.

[0035] The scraper 3 is provided with an upper magnet 8, and the nozzle is provided with a lower magnet 9. A rolling element is provided between the lower magnet 9 and the filter plate 2. The rolling element is a roller 10. A rolling frame is provided on the lower magnet, and the roller 10 is rotatably mounted on the rolling frame. The nozzle 61 and the scraper 3 are coupled by the upper and lower magnets to achieve synchronous movement. The inner wall of the water tank 1 is provided with a limiting slide rail 11, and the lower magnet 9 moves on the limiting slide rail 11. The nozzle 61 is located in front of the front surface of the scraper 3.

[0036] In use, first turn on the air source 7, which supplies air to the nozzle 61 through the diverter pipe 12. Since the nozzle 61 is located below the filter plate 2 and its outlet faces the lower surface of the filter plate 2, the airflow from the nozzle 61 can blow up debris in the mesh of the filter plate 2 and small, thin impurities adhering to the surface of the filter plate 2. Then, start the linear drive mechanism 5, which drives the scraper 3 to move linearly back and forth along the length of the filter plate 2, thereby scraping off the impurities blown up by the nozzle 61. In addition, the scraper 3 is equipped with an upper magnet 8, and the nozzle 61 is equipped with a corresponding lower magnet 9. Due to the coupling effect between the upper and lower magnets, the nozzle 61 will move linearly back and forth along the length of the filter plate 2 in sync with the scraper 3. At the same time, since the nozzle 61 is located in front of the front end surface of the scraper 3, a linkage effect can be formed where the nozzle 61 first blows up the small, thin impurities adhering to the mesh of the filter plate 2 and the surface of the filter plate 2, and the scraper 3 then scrapes off the impurities. The impurity removal effect can be significantly improved. A roller 10 is provided between the lower magnet 9 and the filter plate 2. A limiting slide rail 11 is provided on the inner wall of the water tank 1. The lower magnet 9 moves along the limiting slide rail 11 on the lower surface of the filter plate 2 via the roller 10. The sliding friction between the lower magnet 9 and the filter plate 2 is changed to roller friction, which reduces friction and reduces wear.

[0037] A water-blocking cap 62 is provided above the air outlet of the nozzle 61, and a baffle seat 63 is provided around the nozzle 61. The baffle seat 63 has two side leakage holes 633 on its side, which are arranged symmetrically on the left and right. When the nozzle 61 is not in working condition, the rainwater left on the filter plate 2 flows into the baffle seat 63 and is blocked by the water-blocking cap 62. It sinks into the first baffle surface 631 of the baffle seat and flows out through the side leakage holes 633 on both sides. This ensures that rainwater will not flow into the nozzle 61.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
