[0027] In this embodiment, the material guide mechanism specifically includes: a material guide box 25 fixed on one side of the body 1, a material guide cavity 26 is provided inside the material guide box 25, and a material guide port 28 connected to the material guide cavity 26 is provided on the bottom end surface of the material guide box 25, a discharge port 24 connected to the material guide cavity 26 is provided on the inner wall of the drying chamber 2 at a position corresponding to the material guide cavity 26, a cylinder 27 is fixedly connected to one side of the material guide box 25, and the output shaft of the cylinder 27 passes through the material guide box 25 and is fixedly connected to an arc-shaped sealing plate 29, and the arc-shaped sealing plate 29 is aligned and matched with the discharge port 24.

[0029] In this embodiment, a serpentine groove 31 is provided on the top surface of the square lifting seat 30, and the serpentine groove 31 can prevent the finished iron phosphate from escaping from the square lifting seat 30, and a plurality of evenly distributed micropores 32 are provided on the bottom surface of the serpentine groove 31 to guide the iron phosphate solution out, and the top of the inner wall of the serpentine groove 31 is inclined to better receive the finished iron phosphate.

[0030] In this embodiment, the filtering exhaust component specifically includes: a rotating groove 34 opened in the middle position of the inner wall of one side of the drying chamber 2, the rotating groove 34 is rotatably connected to a disc body 35 matching therewith, and a rotating motor 36 is embedded below the rotating groove 34, the top output shaft of the rotating motor 36 passes through the rotating groove 34 and is fixedly connected to the disc body 35, and an annular groove 37 is opened on the top surface of the disc body 35, and three evenly distributed filter screens 38 are embedded on the bottom end surface of the annular groove 37, an exhaust pipe 39 is fixedly connected to one side of the top surface of the body 1, and the bottom end of the exhaust pipe 39 contacts the disc body 35, and an extension pipe 40 matching the annular groove 37 is fixedly connected to the bottom end of the inner wall of the exhaust pipe 39, and the extension pipe 40 contacts and matches one of the filter screens 38. By setting up the filtering exhaust component, a new filter 38 can be automatically replaced when a large amount of dust adheres to the filter 38 and the filtering effect decreases, and the dirty filter 38 can be sent out to facilitate the staff to clean the dust on it. This process will not affect the normal drying progress or cause dust leakage, and is very convenient.

[0031] In this embodiment, an annular track groove 41 is formed on both inner walls of the annular groove 37, and an arc-shaped slide rail 42 matching the annular track groove 41 is fixedly connected to the outer side surface of the extension tube 40 at a position corresponding to the annular track groove 41, and the arc-shaped slide rail 42 is movably connected to the annular track groove 41. The coordinated use of the annular track groove 41 and the arc-shaped slide rail 42 can improve the stability of the relative displacement between the extension tube 40 and the annular groove 37.

[0032] In this embodiment, the atomizing drying mechanism specifically includes: an atomizing nozzle 5 embedded in the top of the drying chamber 2, a material pump 4 is fixedly connected to the middle position of the top surface of the body 1, and the material pump 4 is connected to the atomizing nozzle 5, and a hot air inlet 3 is opened on the inner wall of the drying chamber 2 on one side of the atomizing nozzle 5, and the hot air inlet 3 is connected to an external hot air source. The atomizing drying mechanism can quickly dry the atomized iron phosphate solution.

[0033] In this embodiment, the height of the bottom end surface of the drying chamber 2 gradually decreases from both sides to the middle position. This arrangement ensures that the droplets falling on the bottom end surface of the drying chamber 2 and the finished iron phosphate can gather toward the rotating tank 7.

[0034] In this embodiment, support bases 6 are fixedly connected to both sides of the bottom end surface of the body 1. The support bases 6 can prevent the body 1 from directly contacting the moisture on the ground.

[0035] The working principle of the present invention is: when in use, first, the iron phosphate solution to be dried is introduced into the material pump 4, the material pump 4 delivers the iron phosphate solution to the atomizing nozzle 5, and the atomizing nozzle 5 then sprays the iron phosphate solution in the drying chamber 2 in an atomized manner. At the same time, the external hot air source delivers hot air to the drying chamber 2 through the hot air inlet 3. During the process, the hot air dries the small iron phosphate droplets, and the small droplets are dried to form finished iron phosphate. Subsequently, the finished iron phosphate and the undried small droplets fall on the bottom surface of the drying chamber 2 under the action of gravity, and finally fall into the rotating trough 7. Then, the finished iron phosphate is sequentially sent out through the rotary drying guide component, and the finished iron phosphate is fully contacted with the hot air during the sending process to achieve further drying. At the same time, the iron phosphate solution collected at the bottom of the rotating trough 7 can be taken out of the rotating trough 7 for drying again. Finally, the hot air in the drying chamber 2 is discharged from the exhaust pipe 39, and the filter 38 of the filter exhaust assembly filters the hot air. In addition, when a large amount of dust is attached to the filter 38 and the filtering effect is reduced, the filter exhaust assembly automatically replaces the new filter 38 and sends the dirty filter 38 out to facilitate the staff to clean the dust on it. This process will not affect the normal drying progress, nor will it cause dust leakage, and it is very convenient.

[0036] The specific working process of the rotary drying guide assembly is as follows: the finished iron phosphate and small droplets enter the rotating tank 7 and fall to the bottom thereof. As time passes, the finished iron phosphate and small droplets at the bottom of the rotating tank 7 increase, and some of the finished iron phosphate and small droplets enter the round groove 31 of the square lifting seat 30. After the iron phosphate solution dryer runs for a certain period of time according to the preset program, the through-type stepping motor 33 runs and slowly rises along the through-type stepping screw 23, thereby driving the square lifting seat 30 to rise. During the process, the small droplets in the round groove 31 flow out along the micropores 32, and most of the finished iron phosphate remains in the round groove 31. When the square lifting seat 30 passes over the square frame 16 and enters the square filter cartridge 17, the driving motor 10 of the driving mechanism drives the main transmission gear 11 to rotate. Since the main transmission gear 11 and the secondary transmission gear 14 are connected by a chain 15, the secondary transmission gear 14 rotates accordingly, and then the shaft 13 connected to the secondary transmission gear 14 rotates accordingly, so that the square frame 16, the square filter cartridge 17 and the optical axis 19 rotate simultaneously. After the square frame 16 rotates counterclockwise by 90 degrees, the through-type stepping screw 23 switches from the initial vertical state to the horizontal state, and the driving motor 10 stops running according to the preset program. At this time, the finished iron phosphate in the round groove 31 pours out and falls into the square filter cartridge 17. The hot air passes through the square filter cartridge 17 and fully contacts with the finished iron phosphate to achieve further drying, and the small droplets mixed therein either flow out of the square filter cartridge 17 or are dried into finished iron phosphate. It should be noted that during the rotation of the square frame 16, the square filter cartridge 17 and the optical axis 19, the lower arc plate 20 and the surface of the optical axis 19 bring out part of the iron phosphate solution from the bottom of the rotating tank 7, and the iron phosphate solution brought out is contacted with hot air again for drying, which effectively improves the dryness and drying and purification efficiency of the finished iron phosphate. After the through-type stepping screw 23 stays in the horizontal state for a preset time, the through-type stepping motor 33 runs again to move horizontally along the through-type stepping screw 23. During the process, the square lifting seat 30 pushes the finished iron phosphate in the square filter cartridge 17 to the discharge port 24. At the same time, the cylinder 27 runs to retract the output shaft, so that the arc sealing plate 29 retreats and no longer blocks the discharge port 24. Subsequently, the square lifting seat 30 pushes the finished iron phosphate in the square filter cartridge 17 from the notch 21 of the upper arc plate 18 to the discharge port 24, and the finished iron phosphate enters the guide cavity 26 along the discharge port 24, and finally is discharged from the guide port 28 to the body 1.After the finished iron phosphate in the square filter cartridge 17 is guided, the square lifting seat 30 is restored to its initial position on the through-type stepping screw 23. Then, the driving motor 10 is driven to drive the main transmission gear 11 to rotate in the opposite direction. The square frame 16, the square filter cartridge 17 and the optical axis 19 rotate clockwise by ninety degrees. The through-type stepping screw 23 is restored from a horizontal state to an initial vertical state. During the process, the lower arc plate 20 rotates along the rotating groove 7 to the bottom of the rotating groove 7, and the finished iron phosphate and small droplets in the rotating groove 7 also enter the circular groove 31 of the square lifting seat 30 again from the gap between the optical axis 19. Then, the second re-drying and guiding is prepared. The above process is repeated repeatedly, so that the finished iron phosphate can be sequentially delivered under the premise of ensuring that the drying process is not affected, and the quality degradation of the dried iron phosphate caused by being in a high temperature environment for a long time can be avoided.

[0037] The specific working process of the filter exhaust assembly is as follows: the hot air passes through the working filter 38 into the extension pipe 40, and then is discharged from the exhaust pipe 39 along the extension pipe 40. As time goes by, a large amount of dust is attached to the working filter 38. In order to avoid the performance degradation of the working filter 38, the rotary motor 36 of the present application runs once every period of time according to the preset program, and each time drives the disc body 35 to rotate 120 degrees, so that the dust-contaminated filter 38 is sent out of the machine body 1 along the rotating groove 34, which is convenient for the staff to clean the dust on it. The next clean filter 38 arrives just below the extension pipe 40 and completes docking with it, and continues to filter the hot air. During the whole process of replacing the filter 38, the extension pipe 40 is always located in the annular groove 37, and the overall sealing effect is good. Only when the extension pipe 40 and the filter 38 overlap, the hot air will pass through, effectively avoiding the leakage of dust.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
