Description

Technical Field

[0001] This utility model belongs to the field of nutrient solution recycling technology for mist planting, and in particular relates to a device for recycling and reusing nutrient solution for mist planting. Background Technology

[0002] Aerial aeration is a method that uses a mist generator to create a mist from nutrient solution. Because the mist is in the form of a fog, the smaller particles of the mist can be fully absorbed by the plants during the cultivation process, thus improving the efficiency of cultivation.

[0003] During the vapor cultivation process, most of the vapor eventually forms droplets, which then converge to form nutrient solution waste. Only a very small portion of the vapor nutrient solution is absorbed by the cultivated plants. If most of the liquefied nutrient solution waste cannot be recycled, it not only causes serious waste of resources but also poses a serious environmental problem for the industry.

[0004] Specifically, the nutrient solution used in aerosol planting is a specially formulated solution, such as inorganic or organic fertilizer solutions, which is extremely harmful to the environment. Therefore, recycling the nutrient waste generated from large-scale aerosol planting and cultivation in actual operations can not only significantly reduce the damage to the ecological environment but also generate significant economic benefits.

[0005] The recovered aerosol solutions, especially organic fertilizer solutions, are often temporarily stored in reservoirs (a certain amount must be stored before centralized processing). However, organic solutions easily breed large amounts of microorganisms and produce a large amount of floating matter, including algae. Therefore, if the recovered aerosol solutions cannot be processed through an efficient treatment system, not only can recyclable aerosol nutrient solutions not be recovered, but secondary pollutants are also generated.

[0006] Therefore, using a simple, efficient, and environmentally friendly treatment system to process the waste vapor nutrient solution generated from vapor planting is of great significance for improving economic benefits and enhancing environmental protection. Utility Model Content

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.

If the specific posture changes, the directional indicator will also change accordingly.

[0025] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0026] Example 1 like Figure 1-5 As shown, a nutrient solution recycling device for aerosol planting includes a multi-stage water treatment system; the multi-stage water treatment system includes several water tanks that cooperate with each other for processing. During operation, the accumulated nutrient solution is processed step-by-step in each of the four stages of the water tanks, including sedimentation, filtration, and treatment of floating and suspended impurities in the recycled nutrient solution.

[0027] Specifically, the multi-stage water treatment system includes a first water tank 1 connected to the feed end (the first water tank 1 is connected to a nutrient solution pumping pipe 11, and the recovered nutrient solution is pumped from the storage tank into the first water tank 1 in accordance with the conventional method disclosed in the prior art).

[0028] According to the process direction, the first water tank 1 and the second water tank 2 adjacent to the first water tank 1, the third water tank 3 adjacent to the second water tank 2 and the fourth water tank 4 adjacent to the third water tank 3 are connected to the discharge end position.

[0029] During the process, the nutrient solution is recovered from the first pool 1 and then passes through the second pool 2 to the fourth pool 4.

[0030] An overflow structure is provided between the adjacent water tanks, through which the material solution overflows from between the water tanks; the overflow structure is set in a gradient in height.

[0031] Specifically, the height of the overflow structure between the first pool 1 and the second pool 2 is greater than the height of the overflow structure between the second pool 2 and the third pool 3, and the height of the overflow structure between the second pool 2 and the third pool 3 is greater than the height of the overflow structure between the third pool 3 and the fourth pool 4.

[0032] The structure described above creates a height difference, allowing the nutrient solution to be treated to be continuously added to the first pool 1, and the treatment is completed in the fourth pool 4 by utilizing the height difference.

[0033] The above method enables step-by-step processing, thereby improving processing efficiency.

[0034] Example 2 like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, a first baffle plate 81 is installed between the first water tank 1 and the second water tank 2, a second baffle plate is installed between the second water tank 2 and the third water tank 3, a third baffle plate is installed between the third water tank 3 and the fourth water tank 4, and an overflow structure is installed on the corresponding first baffle plate to the third baffle plate.

[0035] Specifically, the overflow structure includes a first overflow port on the first baffle plate 81, a second overflow port on the second baffle plate, and a third overflow port on the third baffle plate; the height of the first overflow port is greater than the height of the second overflow port, and the height of the second overflow port is greater than the height of the third overflow port.

[0036] The above structure achieves the height difference of the overflow structure.

[0037] Meanwhile, overflow pipes 8 are respectively connected to the first overflow port, the second overflow port, and the third overflow port. The inlet end of the overflow pipe 8 is connected to the water tank on one side, and the outlet end of the overflow pipe is located in the lower position in the water tank on the other side.

[0038] During operation, when the nutrient waste liquid in the first water tank 1 reaches the height of the first overflow port, the nutrient waste liquid is continuously pumped into the first water tank 1. The nutrient waste liquid continuously flows from the first overflow port into the second water tank 2 through the overflow pipe 8, and so on until it reaches the fourth water tank 4.

[0039] The above structure enables dynamic, step-by-step treatment of nutrient waste liquid. This method not only improves treatment efficiency but also ensures that the nutrient waste liquid undergoes four stages of treatment in four pools, thereby enhancing the treatment effect. The fourth pool (4) is connected to a nutrient solution pumping pipe. After four stages of treatment, the clean nutrient solution treated in the fourth pool (4) is pumped back to the planting system for reuse, following the existing method.

[0040] Water baffle mounting seats 811 (concrete structures formed during the construction of the water tanks) are respectively formed between the first water tank 1 and the second water tank 2, between the second water tank 2 and the third water tank 3, and between the third water tank 3 and the fourth water tank 4. The water baffles are inserted into the water baffle mounting seats 811 for limiting their position. The water baffle mounting seats 811 are U-shaped structures with mounting slots on both sides to mate with the water baffles.

[0041] Example 3 like Figure 1-5 As shown, based on the structure of Example 2, this embodiment, in order to remove floating and suspended impurities, including algae, from the nutrient waste liquid, includes a pair of spaced-apart brush mechanisms 9 installed in the first water tank 1. The brush mechanisms 9 are spaced apart on both sides. Specifically, each brush mechanism 9 includes a frame-shaped mounting bracket 91, within which several brush components 93 are detachably mounted; the brush components 93 are distributed along the length of the frame-shaped mounting bracket 91.

[0042] Specifically, the bristle component 93 includes a bristle rod, which has the same structure as existing bristle devices, and a rigid bristle structure is fixedly connected to the bristle rod; the rigid bristle structure is such as rigid fiber bristles.

[0043] By utilizing the dragging action of the bristles on the rigid brush structure, a large amount of algae in the nutrient waste liquid in the first water tank 1 is adhered during the working process. In contrast, if a traditional filter screen is used, the screen will quickly become clogged.

[0044] Meanwhile, the first pool 1 to the fourth pool 4 are designed as conical settling sections with a conical bottom structure, so that a large number of solid sedimentation impurities will settle down step by step during the flow of the first pool 1 to the fourth pool 4.

[0045] In the first pool 1, a large amount of debris is pulled up by the brush rod-hard bristle structure, which greatly reduces the amount of debris in the water.

[0046] Subsequent operators only need to clean the debris hanging from the brush handle and rigid bristle structure for easy cleaning.

[0047] The aforementioned brush rod is detachable, specifically, its top and bottom are fastened to the mounting bracket 91 by bolts.

[0048] Meanwhile, on the side walls of both sides of the first water tank 1, there are respectively fixed rail rods 92 for inserting mounting brackets 91; guide grooves are opened on the rail rods 92, and when the mounting brackets 91 are inserted into the grooves of the rail rods 92, the mounting brackets 91 are supported at the lower end of the guide grooves of the rail rods 92.

[0049] Example 4 like Figure 1-5 As shown, based on the structure of Example 3, this embodiment further includes a biochemical cotton filter mechanism 10 installed at the discharge end of the multi-stage treatment system in the water tank in order to further filter bacteria and other microorganisms in the nutrient water. The biochemical cotton filter mechanism 10 is used to filter microorganisms in the material solution.

[0050] Specifically, a pair of spaced-apart biochemical cotton filter mechanisms 10 are installed in the fourth water tank 4. Specifically, the biochemical cotton filter mechanism 10 includes a frame-shaped assembly bracket 101 (installed inside the water tank, with the installation method being the same as that of the aforementioned mounting bracket 91, i.e., locking rods 92 for inserting the assembly bracket are fixedly connected to the side walls on both sides of the fourth water tank 4), and biochemical filter cotton 102 is fixedly installed inside the assembly bracket 101.

[0051] Biochemical filter cotton is a conventional filter cloth for filtering liquids disclosed in existing technology. Because the filter pore size of biochemical filter cotton is small, it can filter out impurities such as bacterial colonies in nutrient water, thereby achieving thorough purification of the nutrient solution.

[0052] Example 5 like Figure 1-5 As shown, based on the structure of Example 4, the above-mentioned multi-stage water treatment system also includes a slag discharge pipe system, which is connected to the bottom of the conical settling section 5; a large amount of settled waste is on the conical settling section 5 and is discharged through the slag discharge pipe system.

[0053] Specifically, the slag discharge pipe system includes a main slag discharge pipe 6, which is connected to several branch pipes 61, each connected to a corresponding conical settling section (each branch pipe is equipped with a valve such as a solenoid valve). During operation, when it is necessary to pump out the settled waste, the main slag discharge pipe 6 can be connected to a pump body to pump out the settled material (which, if it is in the form of sludge, can be directly pumped out).

[0054] Example 6 like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 5, in order to further sterilize the nutrient recovery solution (not shown in the figure) during actual operation, submersible sterilization lamps (fish pond sterilization lamps) can be installed in the second and third water tanks 3 in the existing manner.

[0055] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
