Anti-solid hydroponic pot

Description

/ 4 Anti-solid hydroponic pot Field of invention

[001] The present invention falls within the field of hydroponics and aquaponics, specifically dealing with a structure designed for the production of vegetables using water with excess suspended solids. Fundamentals of the invention

[002] The pots and baskets available on the market were designed for hydroponic systems, in which the water is always clean and all nutrients are fully diluted in the water. Research shows that all models available are circular, designed to optimize water flow and support the roots. However, these models were designed and engineered to work with effluents free of suspended solids, which makes it impossible to use these materials when working with hydroponics in biofloc systems or any effluents with a higher concentration of total suspended solids.

[003] The main advantage of this anti-solids vessel is the possibility of working in integrated vegetable production, regardless of the type of effluent (when solids are present). This vessel was designed in a triangular shape, which prevents the adhesion of solids present in the water. The triangular front has holes that allow water to pass through to the roots, simultaneously protecting them from solids in the water. This protection of the roots prevents them from dying due to the deposition of organic matter on them, making integrated vegetable production viable with this type of effluent. Thus, this vessel allows the use of effluents from fish farming tanks for vegetable production in general.

[004] Anti-solid containers are made of plastic, ensuring high durability, which is important when working in aquatic environments as it allows for easy cleaning, and they do not contain toxic elements for vegetables and fish.

[005] Figure 1 shows the design of the invention, measuring each of the areas. Figure 2 shows a front view of the invention. Figure 3 shows the internal view of the invention at the end of cultivation. Figure 4 shows the growth of lettuce roots using the invention. Figure 5 shows lettuce produced using the invention. Description of the invention

[006] The anti-solids hydroponic pot was designed to allow the passage of water and nutrients, protecting the roots from solids suspended in the water. This invention makes hydroponic cultivation possible in effluents previously unsuitable for this activity.

[007] Its front is triangular with holes that retain solids suspended in water, in addition to allowing water flow within the structure where the roots are located. The holes are present on the bottom, which helps the roots have greater access to water and nutrients. The sides are closed to prevent the deposition of solids under the roots.

[008] At the top, the invention has “wings” that allow it to be supported on NFT (Nutrient Film Technique) channels, enabling the parts to be used with NFT channels of different depths, as long as the water passes through the front in a triangular shape.

[009] The invention is made of polyethylene using a 3D printer (2), with a thickness of 2mm, a height of 38mm (this measurement must be in accordance with the height of the NFT channel), a length of 45mm, with 15mm in a triangular shape and the remainder of the base measuring 90mm², and a width of 30mm (1). It has holes in the front and side walls with a diameter of 2mm and also in the base, and two square tabs of 90mm² on the upper part of the support, one on each side, for supporting the object outside the Petition 870240111411, dated 12 / 30 / 2024, page 8 / 15 / 4 gutter. The support must be positioned so that the water comes into contact with the 15 mm parts. Examples of embodiments of the invention

[0010] The anti-solid hydroponic vessel (VHAS) was used for the production of a lettuce cycle in an integrated system with Nile tilapia (Oreochromis niloticus) using biofloc technology.

[0011] According to the results presented in Table 1, it is possible to conclude that the presence of the pots does not influence the water quality parameters for fish or vegetables. A large volume of solids is observed in the water, 35 to 40 mL, which would compromise the growth of the vegetables. Table 1 - Results of average values ​​for daily water parameters. Parameter Box 1 Box 2 Dissolved Oxygen (mg / L) 7.28 7.54 Temperature (C°) 22.25 22.65 Floc Volume (mL) 35.0 40.0

[0012] In Table 2, it can be seen that the presence of VHAS does not retain the solids, since the amount entering before the device and the amount exiting after are equal or very close. Table 2 - Evaluation before and after the removal of water from the gutters with the VHAS.

[0013] Table 3 shows the growth of the vegetables, which is consistent, proving the functionality of VHAS.

[0014] As a result we have lettuces with protected root growth (4), robust (5), clean and 100% free of pesticides. Petition 870240111411, dated 12 / 30 / 2024, page 10 / 15
