Description

Technical Field

[0001] This utility model relates to the field of flower planting equipment technology, and in particular to a flower waste liquid return device. Background Technology

[0002] In the field of flower cultivation, especially in hydroponics, intensive potted plants, and greenhouse cultivation, a large amount of waste liquid is generated during the growth of flowers, including residual nutrient solution after irrigation, substrate leachate, and wastewater from cleaning equipment. These waste liquids contain nutrients such as nitrogen, phosphorus, and potassium that have not been fully absorbed by the flowers, as well as water. If discharged directly, it will not only waste water and fertilizer resources, but may also lead to environmental problems such as soil acidification and groundwater pollution due to nutrient enrichment. Therefore, recycling and reusing flower waste liquid, i.e., liquid recycling, has become an important link in saving planting costs and achieving green planting.

[0003] Existing technologies have the following problems:

[0004] Some devices lack a dedicated liquid collection structure, allowing waste liquid to easily seep through the soil or leak from the container edges, resulting in insufficient return volume and low waste liquid collection efficiency. Furthermore, most devices use only a single filter layer, leading to poor filtration and an inability to effectively remove impurities of varying particle sizes, such as substrate debris, root remains, and fine colloids. These impurities can easily clog irrigation pipes or adhere to the surface of flower roots, causing diseases. Additionally, filter elements are often fixed in place, requiring the removal of numerous connectors for cleaning or replacement, making the process cumbersome, time-consuming, and labor-intensive. Frequent disassembly can also reduce the device's sealing, affecting the stability of the return system and making filter component maintenance inconvenient. Moreover, if the filtered waste liquid is not treated promptly, bacteria and algae can easily grow inside the device, potentially negatively impacting flower growth upon reuse.

[0005] To address these shortcomings, we have proposed a waste liquid recycling device for flowers. Utility Model Content

[0006] The purpose of this invention is to provide a waste liquid recovery device for flowers, which addresses the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a flower waste liquid return device, comprising a collection tank, a return tank connected to the bottom of the collection tank, and two slots opened on the upper and lower inner walls of the return tank, each slot having a support frame inserted inside, and a coarse filter cylinder and a fine filter cylinder respectively installed on the two support frames, a storage trough opened on the lower inner wall of the collection tank, and an ultraviolet germicidal lamp installed inside each storage trough, and a baffle plate provided above the storage trough on the inner wall of the collection tank.

[0008] A maintenance plate is detachably installed on the surface of the liquid collection tank at the positions corresponding to the coarse and fine filter cartridges via fastening screws.

[0009] A control switch is fixedly installed on the surface of the return tank, and the control switch is electrically connected to the ultraviolet germicidal lamp through a wire.

[0010] The coarse filter cartridge is made of 50-100 mesh stainless steel filter screen.

[0011] A drain pipe is fixedly installed on the lower end of one side surface of the liquid collection tank, and a valve is fixedly installed on the surface of the drain pipe.

[0012] The fine filter cartridge is made of 200-300 mesh nylon filter screen.

[0013] The bottom surface of the liquid collection tank is provided with a liquid collection plate, and the liquid collection plate is inclined towards the return tank at an angle of 1°-3°.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a liquid collection plate, the waste liquid of flowers can be quickly collected and introduced into the liquid return system, reducing waste liquid loss, improving the liquid return utilization rate, and reducing resource waste and environmental pollution risks. The two-stage filtration design of coarse filter and fine filter is adopted. The coarse filter removes large particulate impurities, and the fine filter intercepts fine particles, which significantly improves the waste liquid purification effect and avoids impurities clogging pipes or harming the flower roots.

[0016] 2. This utility model features a sliding fit structure between the slot and the support frame, allowing the coarse and fine filter cartridges to be removed simply by pulling out the support frame. This eliminates the need to disassemble complex connecting parts, facilitating daily cleaning and replacement of filter elements, saving labor costs, and improving maintenance efficiency. The added ultraviolet germicidal lamp can sterilize the filtered waste liquid, effectively killing pathogens and microorganisms, reducing the risk of disease transmission during the liquid recycling process, and ensuring the healthy growth of flowers. The detachable inspection plate design facilitates regular maintenance of the device's internal components, ensuring long-term stable operation of the liquid recycling system and extending the device's service life.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3A waste liquid recycling device for flowers includes a collection tank 1, a recycling tank 2 connected to the bottom of the collection tank 1, and two slots 3 opened on the upper and lower inner walls of the recycling tank 2. A support frame 4 is inserted into the two slots 3, and a coarse filter cylinder 5 and a fine filter cylinder 6 are respectively installed on the two support frames 4. A storage trough 7 is opened at the bottom of the inner wall of the collection tank 1, and an ultraviolet germicidal lamp 9 is installed inside the storage trough 7. A baffle 8 is set above the storage trough 7 on the inner wall of the collection tank 1.

[0026] The device uses a collection tank 1 as the main body for collecting waste liquid, and its lower part is connected to a return tank 2 to form a return liquid channel. Two slots 3 on the inner wall of the return tank 2 are used to install a support frame 4. The support frame 4 fixes a coarse filter 5 for primary filtration and a fine filter 6 for secondary filtration, respectively, to achieve graded filtration. The storage trough 7 on the lower part of the inner wall of the collection tank 1 is used to fix an ultraviolet germicidal lamp 9. The baffle 8 above it can block the germicidal lamp to prevent it from directly irradiating the components outside the waste liquid, and at the same time prevent impurities from falling into the storage trough 7.

[0027] Please refer to Figure 2 A maintenance plate 15 is detachably installed on the surface of the liquid collection tank 1 at the positions corresponding to the coarse filter cartridge 5 and the fine filter cartridge 6 via fastening screws 14.

[0028] The inspection plate 15 on the surface of the liquid collection tank 1 corresponds to the position of the coarse filter cartridge 5 and the fine filter cartridge 6, and is fixed by the fastening screws 14. After disassembly, the internal filter components can be directly operated, which is convenient for maintenance or replacement of the filter cartridges.

[0029] Please refer to Figure 2 A control switch 13 is fixedly installed on the surface of the return tank 2, and the control switch 13 is electrically connected to the ultraviolet germicidal lamp 9 through a wire.

[0030] The control switch 13 on the surface of the return tank 2 is connected to the ultraviolet germicidal lamp 9 via a wire, which can manually control the opening and closing of the germicidal lamp and flexibly adjust the sterilization time and timing.

[0031] Please refer to Figure 1 The coarse filter cartridge 5 is made of 50-100 mesh stainless steel filter screen.

[0032] The filter screen is made of 50-100 mesh stainless steel, which is hard and corrosion resistant. It can effectively intercept large particulate impurities in waste liquid, such as fallen leaves, substrate debris, and root residues, to avoid clogging the subsequent fine filtration components.

[0033] Please refer to Figure 1 and Figure 2 A drain pipe 11 is fixedly installed on the lower end of one side surface of the liquid collection tank 1, and a valve 12 is fixedly installed on the surface of the drain pipe 11.

[0034] The drain pipe 11 at the lower end of the collection tank 1 is the outlet of the treated waste liquid. The valve 12 can control the start and stop of the drain and the flow rate, so that the returned liquid can be exported to the irrigation system as needed.

[0035] Please refer to Figure 1 The fine filter cartridge 6 is made of 200-300 mesh nylon filter screen.

[0036] Using 200-300 mesh nylon filter screen, which has good flexibility and smaller pore size, it can filter out fine particles remaining after coarse filtration, such as colloids, microbial remains, fine matrix powder, etc., to further purify waste liquid.

[0037] Please refer to Figure 1 The bottom surface of the liquid collection tank 1 is provided with a liquid collection plate 10, and the liquid collection plate 10 is inclined towards the return liquid tank 2, with an inclination angle of 1°-3°.

[0038] The collection plate 10 in the collection tank 1 is tilted at 1°-3°, using gravity to guide the waste liquid to flow to the return tank 2, avoiding the accumulation of waste liquid in the collection tank 1 and improving collection efficiency.

[0039] Working principle: During use, waste liquid generated during flower planting, such as irrigation residue and substrate exudate, first flows into the collection tank 1, and then naturally flows into the return tank 2. The waste liquid entering the return tank 2 first passes through the coarse filter 5, where large particles are intercepted. The filtered waste liquid continues to flow through the fine filter 6, where fine particles are further removed. The waste liquid after two stages of filtration enters the area below the collection tank 1. At this time, the ultraviolet germicidal lamp 9 is turned on by the control switch 13. When the waste liquid flows through the area irradiated by the germicidal lamp, pathogens and microorganisms are effectively killed. Finally, the treated clean waste liquid is temporarily stored at the bottom of the collection tank 1. By opening the valve 12 on the drain pipe 11, the returned liquid can be discharged to the flower irrigation system, realizing the recycling of waste liquid. If maintenance is required, the inspection plate 15 can be opened by removing the fastening screws 14, and the support frame 4 can be pulled out from the slot 3 to directly clean or replace the coarse filter 5 and the fine filter 6. The operation is convenient and does not affect the overall structure of the device.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
