[0028] The atomizer 10 is fixedly connected with the bottom end of the feeding pipe 2 for atomizing the liquid material into tiny droplets to better contact and dry with hot air. The atomizer 10 in the drawing is a simple schematic diagram.
[0029] With reference to Figure 2 In order to increase the contact area and time of the droplets with hot air, a plurality of blades 12 are arranged in the drying tower main body 1. The blades 12 are rotatably arranged between two mounting plates 13 through a rotating shaft 11. The output end of the servo motor 7 is rotatably penetrated through the drying tower main body 1 and the mounting plates 13 and fixedly connected with the top end of the rotating shaft 11 to drive the blades 12 to rotate.
[0030] Example 2
[0031] With reference to Figures 2-3 On the basis of example 1, the screening mechanism is used for screening the dried particles to obtain particles of different sizes. The screening mechanism comprises a sieve plate 9, a partition cabinet 15, a vertical rod 8, an outer ring 19, a tension spring 20 and an extension plate 16 and the like. The sieve plate 9 is slidably arranged on the other side of the inner wall of the drying tower main body 1 and cooperates with the partition cabinet 15. The partition cabinet 15 is fixedly arranged on one side of the inner wall of the drying tower main body 1, and a side hole 17 is formed on the side of the partition cabinet 15 close to the sieve plate 9, and the sieve plate 9 cooperates with the side hole 17. A through hole 18 is formed in the bottom of the partition cabinet 15, and a separation plate 14 is fixedly arranged. The first discharge end 4 is connected with the lower side of the sieve plate 9, and the second discharge end 5 is connected with the lower side of the through hole 18.
[0032] The vertical rod 8 is fixedly arranged on the top of the frame of the sieve plate 9, and a fixed plate 21 is fixedly arranged on the inner wall of one side of the drying tower main body 1 and slidably sleeved on the outer wall of the vertical rod 8. The top end of the vertical rod 8 is arranged as an inclined surface and cooperates with the blades 12 to push the sieve plate 9 to vibrate and screen when the blades 12 rotate. The outer ring 19 is fixedly sleeved on the outer wall of the vertical rod 8, and the two ends of the tension spring 20 are fixedly arranged on the bottom of the fixed plate 21 and the top of the outer ring 19 respectively to provide a restoring force for the sieve plate 9.
[0033] The sieve plate 9 is arranged obliquely, and the bottom end is located close to one side of the partition cabinet 15, so that smaller particles fall into the partition cabinet 15 through the sieve holes on the sieve plate 9 and are discharged through the through hole 18 and the second discharge end 5. The top of the partition cabinet 15 is also arranged obliquely, and the bottom end is located close to one side of the sieve plate 9. The bottom end of the partition cabinet 15 is provided with an extension plate 16, so that the particles fall onto the sieve plate 9.
[0034] Specifically, the liquid material enters the inside of the drying tower body 1 through the feeding pipe 2, and then is atomized into small droplets by the atomizer 10 and sprayed out, and then contacts hot air entering the inside of the drying tower body 1 through the air inlet pipe 3, and then rapidly evaporates water to realize drying, so as to condense into particles. Then the air is discharged through the air outlet pipe 6, and the servo motor 7 is driven to rotate the plurality of blades 12 through the rotating shaft 11, so as to generate a certain shear force and centrifugal force, so that the liquid droplets entering the inside of the device are more uniformly dispersed in the hot air. This dispersion helps to increase the contact area and contact time of the liquid droplets and the hot air, so that the liquid droplets have enough time to evaporate water and condense into particles, thereby improving the drying efficiency. The condensed particles will fall to the top of the sieve plate 9. At this time, smaller particles will directly fall through the sieve plate 9 and be discharged through the first discharge end 4, while larger particles will slide through the side hole 17 to the inside of the partition cabinet 15, and then fall through the through hole 18 and be discharged through the second discharge end 5, thereby realizing the effect of screening directly in the inside of the drying tower body 1. When the blades 12 rotate, the vertical rod 8 is pressed downward through the inclined surface at the top end of the vertical rod 8. The vertical rod 8 drives the sieve plate 9 to move downward. The vertical rod 8 can be reset by the tension spring 20, so that the sieve plate 9 is in a state of jolting, which helps the screening of the particles.
[0035] The screening mechanism is used to simplify the subsequent use of additional screening devices, thereby reducing the occupied area and cost. The screening mechanism can be used while retaining the subsequent device, thereby further screening on the basis of the original.
[0036] However, as known to those skilled in the art, the working principle and wiring method of the servo motor 7 are common, which belong to conventional means or common general knowledge. Therefore, the working principle and wiring method of the servo motor 7 will not be described here. Those skilled in the art can make any selection or change according to their needs or convenience.
[0037] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
