[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4As shown in the figure, the present utility model provides a uniform air inlet device for a spray drying tower used in the preparation of compound amino acid powder, including: a tower body 1, a rotating rod 3 is fixedly penetrated through the top of the tower body 1 by means of a bearing, a gear 7 is fixedly connected to the outer surface of the rotating rod 3 near the top, a rotary joint 8 is fixed to the top of the rotating rod 3, a ventilation pipe 11 is fixedly connected to the top of the rotary joint 8, an electric push rod 12 is fixedly connected to the bottom of the tower body 1, a connecting block 14 is fixedly connected to the driving end of the electric push rod 12, a tooth row 13 is fixedly connected to the rear surface of the connecting block 14, a plurality of air outlet holes 2 are equidistantly arranged on the outer surface of the rotating rod 3 near the bottom, a hot air blower 9 is fixedly connected to one end of the ventilation pipe 11 away from the rotary joint 8, the position of the tooth row 13 is matched with the position of the gear 7, and the outer surface of the tooth row 13 is meshed with the outer surface of the gear 7. An air filter box 10 is fixedly connected to the output end of the hot air blower 9, an air filter element 18 is arranged on the inner surface of the air filter box 10, connecting pipes 6 are symmetrically and fixedly penetrated through the bottom of the tower body 1, atomizers 5 are fixedly connected to the bottoms of the two connecting pipes 6, and a fixed seat 4 is fixedly connected to the inner surface of the tower body 1, and the top of the fixed seat 4 is rotatably connected to the bottom of the rotating rod 3.

[0024] The overall effect achieved by the entire Example 1 is that by connecting the connecting pipe 6 to an external liquid supply component, the compound amino acid solution is transported through the connecting pipe 6 to the atomizer 5, where it is atomized into tiny droplets and scattered inside the tower body 1. At the same time, the hot air blower 9 is started to generate hot air, which is then transported through the ventilation pipe 11 to the rotating rod 3 and then through the air outlet holes 2 to the inside of the tower body 1. Meanwhile, the air filter element 18 in the air filter box 10 is used to filter out impurities and particulate matters in the air, ensuring that the hot air entering the tower body 1 is clean and pollution-free, which is beneficial to protecting the product quality during the spray drying process. After the hot air enters the rotating rod 3, the reciprocating movement of the electric push rod 12 drives the connecting block 14 and the tooth row 13 to perform linear reciprocating movements, thereby driving the gear 7 to rotate through the tooth row 13. Therefore, under the action of the rotary joint 8 and the bearing, the rotating rod 3 rotates reciprocally inside the tower body 1. During the rotation, with the cooperation of the fixed seat 4, the rotating rod 3 rotates more stably. Thus, the reciprocally rotating rotating rod 3 and the air outlet holes 2 can continuously change the direction of air inflow, making the air flow distribution in the tower more uniform, reducing the concentration or dead angle phenomenon of local air flow, and ensuring the uniformity and drying efficiency of the drying process.

[0025] Example 2, as Figures 1-4 shown, support seats 15 are symmetrically and fixedly connected to the bottom of the tower body 1, a support rod 16 is fixedly connected between the outer surfaces of the two support seats 15, a sliding seat 17 is movably connected to the outer surface of the support rod 16, and the top of the sliding seat 17 is fixedly connected to the bottom of the tooth row 13.

[0026] The effect achieved by the entire Embodiment 2 is that when the tooth row 13 moves in a reciprocating linear motion, it will drive the sliding seat 17 to move along the support rod 16, ensuring that the tooth row 13 can move smoothly under the drive of the electric push rod 12, and it has high practicability.

[0027] Working principle: The compound amino acid solution is transported to the atomizer 5 through the connecting pipe 6 and atomized into tiny droplets that are scattered inside the tower body 1. At the same time, the hot air blower 9 is started to generate hot air, which is then transported to the rotating rod 3 through the ventilation pipe 11 and then to the inside of the tower body 1 through the air outlet holes 2. At the same time, the air filter element 18 in the filter box 10 is used to filter out impurities and particulate matters in the air, ensuring that the hot air entering the tower body 1 is clean and pollution-free, which is beneficial to protecting the product quality during the spray drying process. When the hot air enters the rotating rod 3, the reciprocating motion of the electric push rod 12 will drive the connecting block 14 and the tooth row 13 to perform a linear reciprocating motion. When the tooth row 13 moves in a reciprocating linear motion, it will drive the sliding seat 17 to move along the support rod 16, ensuring that the tooth row 13 can move smoothly under the drive of the electric push rod 12. Thus, the tooth row 13 drives the gear 7 to rotate. Therefore, under the action of the rotary joint 8 and the bearing, the rotating rod 3 performs a reciprocating rotation inside the tower body 1. When rotating, with the cooperation of the fixed seat 4, the rotating rod 3 is more stable during rotation. Thus, the reciprocatingly rotating rotating rod 3 and the air outlet holes 2 can continuously change the direction of the air inflow, making the air flow distribution in the tower more uniform, reducing the concentration or dead angle phenomenon of local air flow, and ensuring the uniformity and drying efficiency of the drying process.

[0028] The wiring diagrams of the atomizer 5, the hot air blower 9, and the electric push rod 12 in the present utility model belong to the common knowledge in the field. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the atomizer 5, the hot air blower 9, and the electric push rod 12 are not explained in detail.

[0029] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
