[0027] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides a vertical organic fertilizer raw material drying device.

[0028] It includes a vertical box body 1, a feed hopper 2 for introducing powder raw materials is arranged on the top of the vertical box body 1, and a discharge hopper 3 for discharging powder raw materials is arranged on the bottom. A plurality of rotating tubes 4 are rotatably arranged in the vertical box body 1, and each rotating tube 4 is also equipped with a plurality of nozzles 5 connected thereto. An air intake pipe 6 is also connected to the vertical box body 1, and one end of the rotating tube 4 is rotated to extend into the air intake pipe 6; an exhaust pipe 8 located above the rotating tube 4 is also fixedly connected to the vertical box body 1; the rotating tube 4 includes two layers staggered up and down in the vertical box body 1, each layer includes a plurality of rotating tubes 4, and a plurality of baffles 10 arranged equidistantly are also arranged between the two layers; a first motor 7 corresponding to the rotating tube 4 is also installed on the vertical box body 1, and the rotating shaft of the first motor 7 is rotated to extend into the vertical box body 1 and is clamped with the corresponding rotating tube 4.

[0029] In the above embodiment, a vertical structure is adopted to reduce the floor space. At the same time, hot air is introduced through the air inlet pipe 6 and then sprayed out through the nozzle 5. In the process, the first motor 7 also drives the rotating tube 4 to drive the nozzle 5 to rotate, so that the hot air can contact the powder raw material more efficiently, thereby achieving efficient drying, and solving the problems of low drying efficiency and uneven drying of organic fertilizer powder raw materials in the prior art; specifically, there is a gap between the baffles 10 provided in the present scheme, and the gap is larger than the particle size of the powder raw material, so that the powder raw material can pass through smoothly (the gap width is about 3-10 times the particle size of the powder raw material, such as 1-3cm), but, during the drying process, since hot air is also sprayed out from the nozzle 5 at the same time, the hot air fills the entire vertical box 1, and The exhaust pipe 8 arranged on the vertical box body 1 is located above the rotating tube 4, so that the hot air ejected is generally upward (the rotating tube 4 is in a rotating state, and the direction of the hot air ejected by the nozzle 5 is changed, but it will generally be led outward from the exhaust pipe 8). The powder raw material generally has a small weight, so it can be turned up and down in the vertical box body 1 under the combined effect of the blowing of the hot air and the blocking of the baffle 10, so as to efficiently contact with the powder raw material and realize efficient drying; in this scheme, if the baffle 10 is not provided, the provided nozzle 5 is driven by the rotating rod (driven by the first motor 7) to eject hot air from various angles to blow the powder raw material, and the powder raw material can also be blown to make the powder raw material turn over, but a part of it may fall to the bottom of the vertical box body 1. (At this time, the discharge hopper 3 is closed and the powder raw materials will not be discharged), so the powder raw materials may not be dried thoroughly, and the baffle rod 10 set up with the cooperation of hot air can make more powder raw materials turn around the baffle rod 10, and will not fall to the bottom, or only a smaller amount will fall to the bottom, so that they can be dried more thoroughly; in particular, the present scheme is provided with three layers of baffles, that is, a plurality of baffle rods 10 are further provided above the upper rotating tube 4 and below the lower rotating tube 4, and the baffle rod 10 located at the top and the baffle rod 10 located at the bottom have the same extension direction and are perpendicular to the baffle rod 10 located in the middle, and the baffle rods 10 form cross squares in the vertical direction, which increases the resistance of the powder raw materials to fall directly to the bottom, and these baffle rods 10 are provided on the two layers of rotating tubes 4 and the baffle rods 10 thereon. With the cooperation of the nozzle 5, more powder raw materials can be turned over in the vertical box 1 during the drying process, so as to achieve a better drying effect and a higher drying efficiency; after the drying is completed, the air inlet pipe 6 stops introducing hot air, and then the discharge hopper 3 below is opened, and the powder raw materials fall downward due to the turning power, and are discharged through the discharge hopper 3, thereby completing the drying operation. In particular, when the powder is discharged through the discharge hopper 3, one of the first motors 7 located in the upper layer, such as the one located in the middle, can also be started, so that the powder raw materials can be blown up to avoid accumulation on the baffle 10. At the same time, the nozzle 5 provides more angles of blowing during rotation, so that the powder raw materials can smoothly fall down to the discharge hopper 3 and then be discharged under the cooperation of gravity;In a more detailed solution, the exhaust pipe 8 includes a pair of exhaust pipes 8 located above the two ends of the rotating pipe 4, so that the airflow in the vertical box 1 is guided above the two sides of the vertical box 1, so that the powder material in the vertical box 1 can be turned over in a wider space. In particular, an exhaust fan can be set at the end of the exhaust pipe 8 to provide a greater traction effect on the airflow in the vertical box 1 to ensure that the hot air is generally upward, so that the powder material can be turned around the baffle 10 with the assistance of the baffle 10. In the process, a small amount of powder material may be sucked into the exhaust pipe 8, and the filter 9 provided will prevent it from being further sucked in. After the hot air stops being introduced, the exhaust fan provided also stops, and the powder material intercepted by the filter 9 will fall below under the influence of gravity, and then be discharged from the discharge hopper 3 with most of the powder material. ;

[0030] In a more detailed exemplary embodiment, Figure 1 , 2 As shown, the nozzles 5 can be multiple and surround the rotating tube 4, so as to introduce hot air at more angles. At the same time, the rotating tube 4 is still rotating, so the introduced hot air can blow the surrounding powder raw materials in a more all-round manner; at the same time, the air intake pipe 6 and the first motor 7 can be arranged alternately, such as the upper layer on one side of the vertical box body 1 is the air intake pipe 6, and the lower layer is the first motor 7, which can make the overall structure more reasonable (such as more balanced counterweights on both sides).

[0031] In a more specific solution, the rotating shaft of the first motor 7 is snap-connected with the rotating tube 4, that is, a mounting seat 26 is fixedly installed in the vertical box body 1 for the rotating tube 4 to be rotatably connected with the end away from the air inlet pipe 6, the rotating shaft of the first motor 7 rotates and extends into the mounting seat 26, and the end of the rotating tube 4 and the end of the rotating shaft of the first motor 7 can be a directional structure snap-connected structure (that is, the end of the rotating shaft is fixedly connected with a square head 14, the end of the rotating tube 4 is a square hole, the square head 14 is snapped into the square hole, and the end of the rotating tube 4 is also blocked at the same time. Although it may not be closed, it will not affect the smooth discharge of hot air into the vertical box body 1), that is, the end of the rotating shaft can be snapped into the end of the rotating tube 4, and the rotating tube 4 is driven to rotate by the first motor 7. At the same time, this can also enable the rotating tube 4 to be pulled out from one end of the mounting tube 11 (the inner diameter of the mounting tube 11 is large enough for the rotating tube 4 with the nozzle 5 to be smoothly taken out), and then targeted maintenance can be carried out, and then reinstalled.

[0032] In a further exemplary embodiment, Figure 1 , 3As shown in Figures 4 and 5, a mounting tube 11 facing each first motor 7 is fixedly connected to the vertical box 1, a mounting sleeve 12 is detachably connected inside the mounting tube 11, and the end of the rotating tube 4 away from the first motor 7 rotates through the mounting sleeve 12, and the air intake pipe 6 is fixedly connected to the mounting sleeve 12 and surrounds the rotating tube 4. The mounting sleeve 12 and the mounting tube 11 can be detachably connected by a screw 13, so that after the screw 13 is removed, the rotating sleeve can be taken out, and then the internal rotating tube 4 and other components can be cleaned with a tool such as a long-handled brush. At the same time, the arrangement of the mounting sleeve 12 and the air intake pipe 6 allows the air intake pipe 6 to smoothly introduce hot air without being affected by the rotation of the rotating tube 4.

[0033] In a further exemplary embodiment, Figure 1 , 6 As shown, a distributing plate 15 in the shape of an umbrella is also provided in the vertical box body 1, and a plurality of strip-shaped holes 16 are provided on the distributing plate 15. A second motor 17 is also installed above the feed hopper 2, and the second motor 17 shaft is fixedly connected to a mounting shaft 18, which rotates downward and passes through the feed hopper 2 and is fixedly connected to the top of the distributing plate 15. The powdered raw materials in the feed hopper 2 first fall onto the distributing plate 15, and the operation of the second motor 17 drives the distributing plate 15 to rotate, so that the powdered raw materials move in a manner of oblique downward rotation. During the movement, part of the powdered raw materials fall through the strip-shaped holes 16, and the rest fall through the lower edge of the distributing plate 15, thereby preventing the powdered raw materials from falling only to the position below the feed hopper 2; further, a material blocking barrel 19 is also fixedly connected in the vertical box body 1, which surrounds the connection between the feed hopper 2 and the vertical box body 1, and the material blocking barrel 19 is small at the top and large at the bottom, and a gap is left between the lower edge and the distributing plate 15 (the gap is relatively large, such as 3-8 cm) At the same time, the material blocking barrel 19 is projected on the distribution disc 15 and the two are coaxially arranged. The material blocking barrel 19 enables the powder raw materials of the feed hopper 2 to be discharged downward through the gap relatively slowly to avoid feeding too quickly; in more detail, the exhaust pipe 8 is arranged below the distribution disc 15, so that the powder raw materials will fall downward and then be flipped up by the influence of the hot air, and will not be directly brought to the filter screen 9 and attached to the filter screen 9. At the same time, the distribution disc 15 arranged in the process can also provide a downward folding guide to the hot air with the cooperation of the exhaust pipe 8, which can also prevent the hot air from carrying the powder raw materials back upward.

[0034] In a further exemplary embodiment, Figure 1As shown, the feed hopper 2 includes a hopper body 20, an outer ring plate 21 fixedly connected to the upper end of the hopper body 20, and a mounting plate 23 fixedly connected to the outer ring plate 21 through a plurality of connecting strips 22, and the second motor 17 is mounted on the mounting plate 23. The powder raw materials are provided between the outer ring plate 21 and the mounting plate 23 arranged above the feed hopper 2, and at the same time, the mounting plate 23 provides a mounting base for the second motor 17; in more detail, the outer ring plate 21 is also fixedly connected to an outer cylinder 24, and the mounting plate 23 is also fixedly connected to an inner cylinder 25 surrounding the second motor 17, and the outer cylinder 24 is smaller in height than the inner cylinder 25, and the powder raw materials are introduced between the inner cylinder 25 and the outer cylinder 24, and the inner cylinder 25 is higher, which can prevent the powder raw materials from entering the inner cylinder 25 and causing adverse effects on the second motor 17.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
