[0023] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] In this document, terms such as "above," "below," "left," "right," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, these positional relationships may change; therefore, they should not be construed as absolute limitations on the scope of protection.

In addition, in embodiments of this utility model, "above," "below," etc., include the stated number.
[0025] The nutrient salt feeding device of this embodiment was proposed in response to numerous problems existing in current nutrient salt feeding devices. Specifically, these problems include: after feeding, the physical properties of nutrient salts easily cause them to adhere to the feeding port, resulting in material waste and requiring cumbersome manual cleaning; furthermore, most existing nutrient salts are packaged in bags, and during the dispensing process, loose threads from the inner bags and fragments from damaged packaging bags can easily get mixed into the material, affecting product quality; additionally, some nutrient salts are in powder or fine particle form, which easily generates dust during feeding, creating a harsh working environment. Based on these problems, this embodiment improves and optimizes the nutrient salt feeding device.
[0026] Reference Figure 1 , Figure 2 The nutrient salt feeding device of this embodiment includes a mixing tank 1. The top of the mixing tank 1 is provided with a feeding port 14 and an exhaust port 13. Nutrient salt is added to the mixing tank 1 through the feeding port 14, and dust generated during the addition of powdered or small-particle nutrient salt is discharged through the exhaust port 13. Furthermore, the feeding port 14 and the exhaust port 13 are located on opposite sides of the top of the mixing tank 1. That is, the feeding port 14 is located on one side near the top of the mixing tank 1, and the exhaust port 13 is located on the other side near the top of the mixing tank 1, thus providing a foundation for the subsequent installation of the feeding trough 2 and the blower 5.
[0027] Feeding port 14 is connected to feeding trough 2. The end of feeding trough 2 away from feeding port 14 is equipped with flushing pipe 3. Nutrient salt material is fed into feeding port 14 connected to it through feeding trough 2 and then into mixing tank 1. This provides operating space for unpacking bags. At the same time, flushing water can be introduced through flushing pipe 3 after feeding to flush the residual material in feeding trough 2 into the mixing tank. It can also flush the residual material adhering to feeding port 14 into mixing tank 1 at the same time, avoiding waste caused by material residue and the trouble of manual cleaning, thereby improving the efficiency of feeding.
[0028] A grid mesh 4 is installed at the connection between the feeding port 14 and the feeding trough 2 to cover the feeding port 14. The grid mesh 4 can physically block loose threads, fragments, etc. generated during the opening of the nutrient salt packaging bags, so as to prevent them from entering the mixing tank 1 with the materials, causing foreign matter to be mixed into the product and resulting in a decline in product quality. Foreign matter blocked by the grid mesh 4 can be manually cleaned periodically or at any time.
[0029] The exhaust port 13 is connected to a blower 5, which is located on the opposite side of the feeding trough 2. This arrangement places the blower 5 and the feeding trough 2 on opposite sides of the mixing tank 1, facilitating installation and operation. Simultaneously, the blower 5 adsorbs dust generated during the feeding of powdered or small granular materials, preventing dust pollution and improving the working environment.
[0030] In this specific implementation, the side wall of the mixing tank 1 is provided with an installation platform 12, which has a support frame 21 for supporting the feeding trough 2. The blower 5 is mounted on the installation platform 12. By designing the installation platform 12 on the side wall of the mixing tank 1, supporting the blower 5, and supporting the feeding trough 21 on the installation platform 12, the strength and stability of the entire feeding device are improved. Specifically, the installation platform 12 can be located near the top of the mixing tank 1, making the structure of the entire feeding device more compact. The installation platform 12 can be arranged around the side wall of the mixing tank 1, or it can be arranged only near the feeding trough 2 and the blower 5. A support leg 11 is provided on the top of the mixing tank 1 to support the mixing tank 1 and improve structural stability.
[0031] The feeding trough 2 is inclined, and at least two support frames 21 are spaced apart along its length, with different heights for the support frames 21. By inclining the feeding trough 2, nutrient salt can be directly fed into the feeding port 14 under the action of gravity. The design of the support frames 21 to support the feeding trough 2 increases its strength and improves the feeding capacity of the nutrient salt. Specifically, the inclination angle of the feeding trough 2 is 30–40 degrees, preferably 35 degrees, to balance the material sliding speed and the space for bag opening operations. More specifically, the feeding trough 2 can be made of stainless steel, with a width of 600–800 mm and a length of 1000–1200 mm.
[0032] Along its width, the flushing pipe 3 covers the feeding trough 2, and the flushing pipe 3 is provided with multiple flushing holes 31 at intervals. By designing multiple flushing holes 31 at intervals in the flushing pipe 3, it can cover all parts of the feeding trough 2, thereby improving the flushing capacity for residual material in the feeding trough 2.
[0033] At least one flushing hole 31 located near the edge of the feeding trough 2 is equipped with a nozzle (not shown in the figure), and the flushing angle of the nozzle is adjustable. By designing a nozzle in the flushing hole 31 near the edge of the feeding trough 2 and adjusting the flushing angle of the nozzle, the nutrient salt remaining at the corners of the feeding trough 2 can be thoroughly flushed away.
[0034] In other specific implementations of this embodiment, two flushing pipes 3 are provided along the height direction, and the flushing holes 31 of the two flushing pipes 3 are staggered. By designing two flushing pipes 3, one above the other, and utilizing the staggered flushing holes 31 of the flushing pipes 3, the flushing coverage area of the feeding tank 2 can be increased, and the flushing water volume can be increased, thereby improving the flushing ability of nutrient salt residue.
[0035] Specifically, fan 5 is a centrifugal negative pressure fan. A wet dust suppression structure is installed at the inlet of fan 5. During the feeding of nutrient salts, fan 5 is turned on, and the negative pressure generated by fan 5 can discharge the dust generated during feeding from exhaust port 13. Furthermore, the designed wet dust suppression structure further reduces the amount of dust spreading outward, improving the working environment.
[0036] The outer side of the feeding port 14 is provided with hanging points, and the edge of the grid mesh 4 is provided with hooks that cooperate with the hanging points. The cooperation of the hooks and hanging points secures the grid mesh 4 to the feeding port 14, preventing displacement of the grid mesh 4 under the impact of the fed material. Specifically, the grid mesh 4 is provided with spaced-apart grid bars, with an adjacent grid bar spacing of 30-50mm, which improves the ability to block foreign objects from appearing in the packaging bags of different nutrients during bag opening. Specifically, the grid mesh 4 can be made of 304 stainless steel.
[0037] The nutrient salt feeding device in this embodiment achieves a foreign object interception rate of over 99% through the grid mesh 4, which intercepts foreign objects such as inner bag threads and packaging fragments; the negative pressure adsorption of the fan 5 significantly reduces dust during the feeding process, improving the working environment; and the flushing pipe 3 at the end of the feeding trough 2 reduces the amount of material residue on the inner wall of the feeding port 14 by over 90%, eliminating the need for frequent manual cleaning, shortening the feeding operation time by 15% to 20%, improving work efficiency, and reducing material waste.
[0038] Where the embodiments do not contradict each other, at least some of the technical solutions in each embodiment can be recombine to form the essential technical solution of this utility model. Of course, the embodiments can also reference or include each other. Furthermore, it should be noted that adaptive adjustments and modifications made by those skilled in the art when recombinating the technical means described in the embodiments will also fall within the protection scope of this utility model.
[0039] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
