[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Embodiment 1: A material pretreatment device for fertilizer production, such as Figure 1-Figure 4As shown, it includes a first supporting belt 2, a vibrating screen 4, a second supporting belt 10, a drying auxiliary device 3 arranged above the first supporting belt 2, and a drying auxiliary device 3 arranged above the second supporting belt 10. A discharge barrel 1 is arranged on one side of the first supporting belt 2, and the discharge port of the discharge barrel 1 is located above the first supporting belt 2. The drying auxiliary device 3 is located above the processing port of the discharge barrel 1. Rotating rollers 11 are rotatably arranged on opposite sides of the first supporting belt 2. A plurality of filter ports 6 are opened in the lower half of the interior of the vibrating screen 4. A plurality of vibration motors 7 are fixedly connected to the lower end of the vibrating screen 4. One side of the upper end of the second supporting belt 10 is located below the filter ports 6. Rotating rollers 11 are arranged on both sides of the interior of the second supporting belt 10. When the device is running, the fertilizer raw materials are moved and heated and dried twice under the rotation support of the first supporting belt 2 and the second supporting belt 10, wherein vibration separation of the raw materials is added to improve the full drying effect of the raw materials. Specifically, the fertilizer raw materials are flowed to the top of the first supporting belt 2 under the support of the discharge barrel 1, and then are separated by two rotating rollers. Under the rotation support of the movable roller 11, the first support belt 2 drives the raw material above it to rotate, and at the same time, under the heating and irradiation of the drying auxiliary device 3, the effect of drying the raw material on the first support belt 2 while moving it is achieved. Furthermore, under the continued rotation of the first support belt 2, the raw material above it flows into the inside of the vibrating screen 4, and the circulation of the raw material is isolated under the restriction of the fixed specifications of the filter port 6. Under the vibration of multiple vibration motors 7, the raw material larger than the specification of the filter port 6 is split, and finally the raw material of appropriate specification falls onto the second support belt 10, and then under the rotation of the second support belt 10 and the re-heating and drying of the drying auxiliary device 3, the separated raw material and the raw material of appropriate specification are dried again, thereby achieving a process of limited drying, separation and then drying of the raw material, which can further increase the specification limit of the raw material and increase its drying degree before stirring and preparation, and at the same time, can increase the dryness of the material during stirring, which is conducive to improving the stability and efficiency of fertilizer preparation.

[0026] like Figure 1-Figure 4 As shown, a limit stopper 5 is inserted inside the vibrating screen 4, and an auxiliary frame 13 is fixedly connected to the upper end of the limit stopper 5. The limit stopper 5 is used to limit the vibration of the fertilizer raw material inside the vibrating screen 4. Under the limitation of the limit stopper 5, when the larger raw material particles inside the vibrating screen 4 are vibrated upward, they can collide with the lower end of the limit stopper 5, thereby achieving the effect of crushing the larger particles into smaller particles, so that the raw material particles can meet the flow standards and be dried again.

[0027] like Figure 1-Figure 4As shown, the discharge port of the discharge barrel 1 is plugged into the auxiliary frame 13 and extends into the interior thereof, the first support belt 2 is rotatably arranged in the auxiliary frame 13, the rotating roller 11 is rotatably connected to the auxiliary frame 13 and extends to the outside thereof, the drying assistant 3 is fixedly connected to the auxiliary frame 13 through a plurality of fixed connecting rods 12, and the drying assistant 3 is fixedly connected to the fixed connecting rods 12. By limiting the auxiliary frame 13, the stability of the discharge angle of the discharge barrel 1 is ensured, and with the support of the auxiliary frame 13 on a plurality of fixed connecting rods 12, the drying assistant 3 is structurally guaranteed to have the effect of multi-angle drying of the raw materials on the first support belt 2, and by setting both drying assistants 3 as infrared dryers with model GHT680, it is possible to perform stable and efficient heating and drying steps on the raw materials.

[0028] Embodiment 2: A material pretreatment device for fertilizer production, such as Figure 1-Figure 4 As shown, a limit frame 9 is set below the auxiliary frame 13, and the vibration motor 7 is fixedly set on the inner wall of the limit frame 9 through a support platform 8, and the support platform 8 is fixedly set at the lower end of the vibration motor 7. The vibration screen 4 is located inside the limit frame 9. The stability of the vibration screen 4 driven by the vibration motor 7 to vibrate is ensured by the support of multiple support platforms 8 inside the limit frame 9, and the position of the vibration screen 4 is stable when multiple vibration motors 7 are vibrating and running, and the position of the vibration screen 4 is stable by the limitation of the auxiliary frame 13 and the limit frame 9.

[0029] like Figure 1-Figure 4 As shown, the lower end of the limit frame 9 is fixedly connected to a bottom support frame 14, the second support belt 10 is rotatably arranged inside the bottom support frame 14, the drying auxiliary device 3 is fixedly arranged in the upper half of the bottom support frame 14, the rotating roller 11 is rotatably connected to the second support belt 10, and electrical connectors 15 are arranged on the outer sides of the auxiliary frame 13 and the bottom support frame 14. The two electrical connectors 15 are used to supply power to the two drying auxiliary devices 3. The raw materials with limited specifications are driven to move by the second support belt 10 under the rotation support of the rotating roller 11, and the separated raw material particles are heated again by the heating of the drying auxiliary device 3 above it, thereby further improving the sufficiency of heating the raw materials, thereby improving the sufficiency of the device for drying the raw materials.

[0030] Working principle: The fertilizer raw materials are flowed to the top of the first support belt 2 under the support of the discharge barrel 1, and then the first support belt 2 drives the raw materials above it to rotate under the rotation support of the two rotating rollers 11. At the same time, under the heating and irradiation of the drying auxiliary device 3, the effect of drying the raw materials on the first support belt 2 while moving is achieved. Further, under the continued rotation of the first support belt 2, the raw materials above it flow into the inside of the vibrating screen 4, and the raw materials are circulated and isolated under the restriction of the fixed specifications of the filter port 6. Under the vibration of multiple vibration motors 7, the raw materials larger than the specifications of the filter port 6 are split, and finally the raw materials with appropriate specifications fall onto the second support belt 10, and then under the rotation of the second support belt 10 and the re-heating and drying of the drying auxiliary device 3, the separated raw materials and the raw materials with appropriate specifications are dried again, thereby achieving a process of limiting the drying of the raw materials, separating and then drying them. After the specification restrictions on the raw materials and the degree of drying are increased, stirring and preparation can be carried out, and the dryness of the materials during stirring can be increased, which is conducive to improving the stability and efficiency of fertilizer preparation.
