Description

Technical Field

[0001] This utility model relates to the field of soilless cultivation equipment technology, specifically a soilless cultivation nutrient solution recycling device. Background Technology

[0002] Soilless cultivation is a modern agricultural technology that provides plants with the necessary nutrients for growth using nutrient solutions instead of soil. This method allows for precise control of environmental conditions, increasing crop yield and quality while reducing water and fertilizer use. Soilless cultivation systems are widely used in greenhouse cultivation, urban agriculture, and scientific research.

[0003] Currently, when hydroponics systems need to change the nutrient solution, the nutrient solution in the cultivation tank is simply poured out and replaced with new nutrient solution, which results in a lot of waste and increases costs. Utility Model Content

[0004] The purpose of this invention is to provide a soilless cultivation nutrient solution recycling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this disclosure provides a soilless culture nutrient solution recycling device, including a tank and an overflow shell;

[0006] The housing has an internal cavity for accommodating the overflow housing;

[0007] The overflow housing includes an outer shell and an inner shell. The interior of the inner shell has a receiving cavity for communicating with the nutrient solution outlet of the incubator. The inner shell is installed inside the outer shell. An overflow channel is defined between the outer wall of the inner shell and the inner wall of the outer shell. The overflow channel is used for the nutrient solution in the receiving cavity to flow through.

[0008] Optionally, the recycling device further includes a first filter screen;

[0009] Both the outer shell and the inner shell are formed as a box-shaped structure with one end open and the other end closed, and the open end of the outer shell is flush with the open end of the inner shell;

[0010] The first filter screen is located inside the receiving cavity and is detachably connected to the inner housing.

[0011] Optionally, the recycling device further includes a limiting element;

[0012] The first filter screen has an annular skirt at its edge, and the bottom surface of the annular skirt is used to fit against the top of the inner shell;

[0013] The limiting member is constructed in the shape of a square, and an annular groove is formed at the bottom of the limiting member, which is inserted into the top of the inner shell.

[0014] The annular skirt is located between the annular groove and the top of the inner housing.

[0015] Optionally, the housing has a filtration chamber and a recovery chamber, the filtration chamber is connected to the recovery chamber, and a liquid outlet is formed on the recovery chamber;

[0016] The overflow housing is disposed in the filter chamber.

[0017] Optionally, the recycling device further includes a second filter screen, and the housing includes a partition, a bottom plate, and a plurality of side plates surrounding the bottom plate;

[0018] The base plate and the plurality of side plates together define the cavity;

[0019] The partition is located inside the cavity to separate the filtration chamber from the recovery chamber;

[0020] The second filter screen is detachably mounted on the partition plate, and the second filter screen is configured to filter the nutrient solution flowing from the filter chamber to the recovery chamber to remove impurities.

[0021] Optionally, the partition plate is provided with an upward-facing groove, and a slot extending circumferentially along the groove is formed on the groove;

[0022] The two opposite sides of the second filter screen are movably inserted into the slots.

[0023] Optionally, the recycling device further includes a sealing gasket;

[0024] The sealing gasket is provided inside the slot.

[0025] Through the above technical solution, suspended solids or impurities in the nutrient solution can naturally settle to the bottom of the container. Therefore, when the nutrient solution in the container reaches a certain height, the clearer nutrient solution (i.e., the upper layer liquid) will overflow into the overflow channel between the inner and outer shells. During the overflow process, even finer suspended solids can continue to settle in the overflow channel, further purifying the nutrient solution. The nutrient solution after overflowing can finally collect in the cavity of the tank. At this point, the nutrient solution has undergone two sedimentation processes and is relatively pure. After appropriate treatment (such as filtration, disinfection, pH adjustment, nutrient supplementation, and removal of harmful substances), it can be recycled to ensure the nutrient conditions required for plant growth. This design can effectively separate solid impurities in the nutrient solution, making the recycled nutrient solution more suitable for reuse, while reducing the impact of impurities on plant growth. In addition, purifying the nutrient solution through physical sedimentation is a low-cost and simple-to-operate method.

[0026] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0033] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0034] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" are generally defined by the orientation of the drawing in the accompanying drawings, and "inner" and "outer" refer to the inner and outer contours of the relevant components. Furthermore, terms such as "first" and "second" are used only for descriptive distinction and should not be construed as indicating or implying relative importance.

[0035] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0036] like Figures 1 to 3 As shown, this disclosure provides a hydroponic nutrient solution recycling device, including a box body 10 and an overflow shell 20. The box body 10 has a cavity 11 inside, which is used to accommodate the overflow shell 20. The overflow shell 20 includes an outer shell 21 and an inner shell 22. The inner shell 22 has a receiving cavity 23 inside for communicating with the nutrient solution outlet of the cultivation box. The inner shell 22 is installed inside the outer shell 21. An overflow channel 24 is defined between the outer wall of the inner shell 22 and the inner wall of the outer shell 21. The overflow channel 24 is used for the nutrient solution in the receiving cavity 23 to flow through.

[0037] Through the above technical solution, since suspended matter or impurities in the nutrient solution can naturally settle to the bottom of the receiving cavity 23, when the nutrient solution in the receiving cavity 23 reaches a certain height, the clearer nutrient solution (i.e., the upper liquid) will overflow into the overflow channel 24 between the inner shell 22 and the outer shell 21. During the overflow process, even finer suspended matter can continue to settle in the overflow channel 24, thereby further purifying the nutrient solution. The nutrient solution after passing through the overflow channel 24 can finally be collected in the cavity 11 of the box 10. At this time, the nutrient solution has undergone two sedimentation processes and is relatively pure. After appropriate treatment (such as filtration, disinfection, pH adjustment, nutrient supplementation, removal of harmful substances, etc.), it can be recycled to ensure the nutrient conditions required for plant growth. This design can effectively separate solid impurities in the nutrient solution, making the recycled nutrient solution more suitable for reuse, while reducing the impact of impurities on plant growth. In addition, purifying the nutrient solution through physical sedimentation is a low-cost and simple-to-operate method.

[0038] Optionally, the containment cavity 23 can be connected to the nutrient solution outlet of the incubator via a pipe, thereby allowing the nutrient solution to flow into the containment cavity 23.

[0039] As one implementation method, such as Figures 1 to 2 As shown, the recycling device also includes a first filter screen. The outer shell 21 and the inner shell 22 are both formed into a box-shaped structure with one end open and the other end closed. The open end of the outer shell 21 is flush with the open end of the inner shell 22. The first filter screen is located in the receiving cavity 23 and is detachably connected to the inner shell 22.

[0040] After the nutrient solution flows from the nutrient solution outlet of the incubator into the receiving cavity 23 of the inner shell 22, it first passes through a first filter screen (not shown). This removes larger suspended solids and impurities, reducing the number of particles that need to be processed during subsequent sedimentation. Furthermore, since the first filter screen is removable, it can be periodically removed for cleaning or replacement, preventing suspended solids and impurities from clogging the filter pores and maintaining filtration efficiency. The addition of the first filter screen significantly improves the purification level of the nutrient solution, reducing the impact of suspended solids and impurities on plant roots and the entire system. In other words, through pre-filtration and secondary sedimentation using the first filter screen, impurities in the nutrient solution can be effectively removed, improving the efficiency and safety of recycling.

[0041] Furthermore, since the open end of the outer shell 21 is flush with the open end of the inner shell 22, the two can be easily assembled together, and the nutrient solution can flow smoothly from the inner shell 22 to the overflow channel 24.

[0042] In one embodiment, the first filter screen is detachably connected to the inner housing 22, such as Figure 3 As shown, the recycling device also includes a limiting member 30. The edge of the first filter screen is formed with an annular skirt. The bottom surface of the annular skirt is used to fit against the top of the inner shell 22. The limiting member 30 is constructed in a U-shape. An annular groove 31 is formed at the bottom of the limiting member 30. The annular groove 31 is inserted into the top of the inner shell 22. The annular skirt is located between the annular groove 31 and the top of the inner shell 22.

[0043] The limiting member 30 securely fixes the first filter screen to the inner housing 22, preventing displacement caused by water flow impact or movement. Furthermore, since the limiting member 30 is plug-in type, the filter screen can be easily removed from the inner housing 22 for regular cleaning or replacement.

[0044] As one implementation method, such as Figures 1 to 2As shown, the housing 10 has a filter chamber 111 and a recovery chamber 112. The filter chamber 111 is connected to the recovery chamber 112. An outlet 113 is formed on the recovery chamber 112. An overflow housing 20 is disposed in the filter chamber 111.

[0045] The filter chamber 111 is the area where the overflow shell 20 is located. The filter chamber 111 is used to process and pre-filter the nutrient solution coming out of the incubator.

[0046] The recovery chamber 112 is connected to the filtration chamber 111, and the recovery chamber 112 is used to store the treated nutrient solution. In addition, the recovery chamber 112 is provided with a liquid outlet 113, which is used to discharge the treated nutrient solution for reuse.

[0047] Specifically, firstly, the nutrient solution, after preliminary filtration and sedimentation, flows into the recovery chamber 112 through the channel between the filtration chamber 111 and the recovery chamber 112. Then, the processed nutrient solution stored in the recovery chamber 112 can be returned to the cultivation system for use through the outlet 113. Finally, the sediment at the bottom of the receiving cavity 23, the bottom of the overflow channel 24, and the bottom of the filtration chamber 111 is cleaned periodically, and the first filter screen is cleaned or replaced to ensure the normal operation of the device.

[0048] As one implementation method, such as Figures 1 to 2 As shown, the recycling device also includes a second filter 40. The housing 10 includes a partition 12, a bottom plate, and a plurality of side plates 13 surrounding the bottom plate. The bottom plate and the plurality of side plates 13 together define a cavity 11. The partition 12 is located in the cavity 11 to separate the filter chamber 111 from the recycling chamber 112. The second filter 40 is detachably mounted on the partition 12. The second filter 40 is configured to filter the nutrient solution flowing from the filter chamber 111 to the recycling chamber 112 to remove impurities.

[0049] The second filter screen 40 is detachably mounted on the partition 12 and is used to filter the nutrient solution flowing from the filter chamber 111 to the recovery chamber 112, further removing residual fine impurities. The dual filtration design of the first and second filter screens 40 can more thoroughly remove impurities from the nutrient solution. The clear separation between the filter chamber 111 and the recovery chamber 112 allows for more organized nutrient solution processing and improves processing efficiency. Both the first and second filter screens 40 are detachable for easy cleaning or replacement.

[0050] As one embodiment where the second filter screen 40 is detachably connected to the partition 12, such as Figures 1 to 2 As shown, the partition 12 has an upward-facing groove, and a slot 121 extending circumferentially along the groove is formed on the groove. The opposite sides of the second filter screen 40 are respectively movably inserted into the slot 121.

[0051] The partition 12 has an upward-opening groove that extends through the thickness of the partition 12, for holding the second filter screen 40. Furthermore, slots 121 extending circumferentially along the edge of the groove are formed, designed to fit tightly with the edge of the second filter screen 40. The opposite sides of the second filter screen 40 are designed to be inserted into the slots 121, for example, in a sheet-like or flanged shape, allowing it to slide into the slots 121. This design simplifies and speeds up the installation and removal of the second filter screen 40, facilitating routine maintenance and cleaning.

[0052] To further improve the sealing between the second filter screen 40 and the partition 12, as one implementation method, such as Figures 1 to 2 As shown, the recycling device also includes a sealing gasket 50, which is disposed in the slot 121.

[0053] The sealing gasket 50 is located within the slot 121. When the second filter screen 40 is inserted, the sealing gasket 50 tightly wraps around the edge of the filter screen, forming a seal. In other words, the sealing gasket 50 effectively fills the tiny gaps between the filter screen and the slot 121, preventing unfiltered nutrient solution from flowing into the recovery chamber 112 through these gaps. Furthermore, the sealing gasket 50 reduces friction between the filter screen edge and the slot 121, protecting the filter screen from wear and thus extending its service life.

[0054] Alternatively, the sealing gasket 50 may be made of rubber, silicone, or fluororubber, and this disclosure does not impose any limitation thereon.

[0055] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0057] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
