The axis of the drying barrel 420 is parallel to the direction of the primary drying nozzle 301, and the distances between the drying barrel 420, the primary drying nozzle 301 and the axis of the drying tank 2 are the same. Figure 1 , Figure 3 As shown, the top of the drying barrel 420 is provided with an opening 421, and the bottom thereof is provided with a vent hole 422; when the drying barrel 420 rotates to a position corresponding to the initial drying nozzle 301, the hot air flow passes through the through hole to blow the material inside the drying barrel 420, and the material particles are affected by the air flow, part of the water evaporates, and the gravity becomes lighter and moves upward to present a suspended state until the material moves to the top of the drying barrel 420;

[0030] The jet discharging mechanism 5 is arranged between the plurality of drying cylinders 420 and located above the drying cylinders 420. The jet discharging mechanism 5 has a plurality of discharging nozzles 501 along the horizontal direction. The material moving to the top of the drying cylinder 420 is acted upon by the discharging nozzles 501 and moves outwards into the primary drying tank 2.

[0031] A drying and forming mechanism 6, wherein a discharge pipe 201 is provided at the bottom of the primary drying tank 2, and the drying and forming mechanism 6 is arranged below the discharge pipe 201;

[0032] The material entering the primary drying tank 2 moves downward along the inner wall of the primary drying tank 2, is discharged from the discharge pipe 201, and then undergoes a secondary drying effect of the drying forming mechanism 6, which helps the material to form a dry particle form with a compact structure;

[0036] Specifically, as shown in the figure, the primary drying mechanism 3 further includes a primary drying air inlet pipe 302, which passes through the bottom of the drying tank 1 from bottom to top, and extends from the discharge pipe 201 to the primary drying tank 2, and the primary drying nozzle 301 is connected to the primary drying air inlet pipe 302 through a pipeline;

[0038] After the material is discharged from the discharge pipe 201, it is dispersed to the guide platform 602 by the material distribution platform 601. The material on the guide platform 602 is affected by the airflow of the drying and forming nozzle 603. The material particles rise again and are blocked by the forming guide cloth 604. The material particles roll along the surface of the forming guide cloth 603. On the one hand, they are affected by the airflow, which accelerates the evaporation of water during the rolling process. On the other hand, they are affected by the air pressure of the airflow and the blocking effect of the forming guide cloth 604, rolling to form a compact structure, reducing the fragmentation of particles and ensuring product quality.

[0039] In order to facilitate the adjustment of the blocking effect of the forming guide cloth 604, in a further embodiment, as Figure 1 As shown, the discharge pipe 201 is coaxially arranged with the primary drying tank 2, and an annular connecting seat 202 is provided on the discharge pipe 201.

A vertical telescopic component 606 is fixed on the drying tank 1 and is connected to the material guide seat 605;

[0040] The annular forming material guide cloth 604 has a conical surface structure, and the material guide seat 605 is driven to move vertically by the vertical telescopic component 606, and the inclination between the conical surface structure and the horizontal plane can be adjusted, thereby changing the strength of the forming material guide cloth 604's blocking effect on material particles;

[0041] In order to facilitate the discharge of the dried and formed material, in a further embodiment, as Figure 1As shown, the material distribution platform 601 is a conical structure and its bottom extends to the outside of the discharge pipe 201. The edge of the material guide platform 602 is fixedly connected to a separation cylinder 607 located inside the material guide seat 605. The material moves along the forming material guide cloth 604, and after drying and forming, it moves along the inner surface of the material guide seat 605 to between the material guide seat 605 and the separation cylinder 607 and then falls;

[0042] In order to strengthen the rolling motion of the material particles, in a further embodiment, the outer side of the material guide seat 605 is coaxially rotatably connected with a sliding seat 608 connected to the vertical telescopic component 606, the outer side of the material guide seat 605 is provided with a transmission gear 609, and a rotating driving member 610 meshing with the transmission gear 609 is fixed on the sliding seat 608, the connecting seat 202 is rotatably connected with the discharge pipe 201, and a plurality of sets of synchronization components are provided between the material guide seat 605 and the connecting seat 202;

[0043] The material guide seat 605 is driven to rotate by the rotating driving member 610, and the material guide seat 605 drives the connecting seat 202 to rotate through the synchronous component. When the connecting seat 202 and the material guide seat 605 rotate synchronously, the forming material guide cloth 604 produces a rotating effect, and the material particles are affected by the forming material guide cloth 604 to produce a more effective rolling motion;

[0044] Specifically, the synchronization component includes a first connecting rod 611 rotatably connected to the material guide seat 605, and a second connecting rod 612 rotatably connected to the connecting seat 202, the first connecting rod 611 and the second connecting rod 612 are rotatably connected, the rotation axes of the first connecting rod 611 and the second connecting rod 612 are horizontal, the first connecting rod 611, the second connecting rod 612 and the axis of the discharge pipe 201 are located in the same vertical plane, and the first connecting rod 611 and the second connecting rod 612 only rotate in this vertical plane.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
