Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and in particular to a dryer for compound fertilizer production. Background Technology

[0002] In the production process of compound fertilizers, removing excess moisture is a crucial step. This is because excessive moisture content can have many adverse effects on fertilizer quality and severely impact its storage stability. From a fertilizer quality perspective, residual moisture may trigger chemical reactions between fertilizer components, leading to the loss of effective nutrients or their transformation into other substances that are not easily absorbed by crops, thereby reducing the fertilizer's effectiveness.

[0003] In existing technology, by setting an outer cylinder on the outside of the drying cylinder and connecting the outer cylinder with the flue, hot air can be introduced into the gap between the drying cylinder and the outer cylinder to indirectly dry the compound fertilizer inside the drying cylinder. At the same time, by setting multiple air inlets on the inner wall of the drying cylinder, hot air can be introduced into the drying cylinder through the air inlets to directly dry the compound fertilizer, so that the hot air and the compound fertilizer are in uniform contact and the compound fertilizer is thoroughly dried.

[0004] However, existing technologies may cause clumping in compound fertilizers containing moisture before drying, resulting in clumped compound fertilizers after drying. This leads to larger particle sizes in un-crushed compound fertilizers and uneven heat distribution during the drying process, which may result in uneven particle sizes of the dried fertilizer and affect its effectiveness. Therefore, a dryer for compound fertilizer production is needed to solve the above problems. Utility Model Content

[0005] To overcome the problem of large particle size in uncrushed compound fertilizer.

[0006] The technical solution of this utility model is as follows: a dryer for compound fertilizer production, including a base plate; it also includes a support plate and a screening assembly. Support legs are fixedly connected to the bottom of the base plate, and the screening assembly is located on the right side of the base plate. The support plate is fixedly connected to the bottom of the base plate, and a discharge pipe is fixedly connected to the top of the support plate. A drying drum is fixedly connected to the outside of the discharge pipe, and a motor is fixedly connected to the outside of the discharge pipe. A crushing roller is fixedly connected to the outside of the motor, and a gear is fixedly connected to the outside of the crushing roller. A gear is meshed with the outside of the gear, and a crushing roller is fixedly connected to the outside of the gear. A rotating disk is fixedly connected to the outside of the crushing roller, away from the gear. A connecting belt is driven to the outside of the rotating disk, and a rotating disk is driven to the end of the connecting belt away from the rotating disk. A tilting conveyor assembly is located outside the rotating disk.

[0007] Preferably, the tilting conveyor assembly includes a spiral blade, which is fixedly connected to the outside of the rotating disk II. A stirring scraper is fixedly connected to the outside of the spiral blade, and a funnel is fixedly connected to the top of the discharge pipe.

[0008] Preferably, when the first rotating disk rotates, the connecting belt drives the second rotating disk to rotate simultaneously.

[0009] Preferably, the discharge pipe has a through hole, and the rotating disk is rotatably connected to the inside of the discharge pipe through the through hole.

[0010] Preferably, the screening assembly includes a screening box, which is fixedly connected to the outside of the base plate. A mounting frame is fixedly connected to the outside of the screening box, and a second motor is fixedly connected to the outside of the mounting frame. A double-headed cam is fixedly connected to the output end of the second motor. A fixed base is fixedly connected to the outside of the screening box, and a sliding rod is slidably connected inside the fixed base. A connecting plate is fixedly connected to the outside of the sliding rod, and a first screen is fixedly connected to the outside of the connecting plate.

A sliding rod is fixedly connected inside the screening box, and a second spring is provided at the midpoint between the outside of the first screen and the inside of the screening box. A discharge plate is fixedly connected inside the screening box.

[0011] Preferably, the screening box is provided with a sliding groove, and the screen is slidably connected to the inside of the screening box through the sliding groove.

[0012] Preferably, when the double-headed cam approaches the sliding rod, the sliding rod moves downward; when the double-headed cam moves away from the sliding rod, the sliding rod slides downward.

[0013] The beneficial effects of this invention are as follows: Gear meshing drives gear two and crushing roller two to rotate synchronously, achieving initial crushing of agglomerated raw materials. When crushing roller two rotates, it synchronously drives rotating disk one, which in turn is transmitted to rotating disk two via a connecting belt, causing the spiral blades to rotate. The spiral blades, on one hand, transport the crushed raw materials to the drying drum, and on the other hand, coordinate with the rotating agitator scraper to improve drying uniformity through stirring. This design effectively prevents agglomeration from affecting subsequent drying effects and ensures production quality. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment: a dryer for compound fertilizer production, including a base plate 1; it also includes a support plate 21 and a screening assembly. Support legs 4 are fixedly connected to the bottom of the base plate 1, and the screening assembly is located on the right side of the base plate 1. The support plate 21 is fixedly connected to the bottom of the base plate 1, and a discharge pipe 22 is fixedly connected to the top of the support plate 21. A drying drum 23 is fixedly connected to the outside of the discharge pipe 22. A motor 24 is fixedly connected to the outside of the discharge pipe 22. A crushing roller 25 is fixedly connected to the outside of the motor 24. A gear 26 is fixedly connected to the outside of the crushing roller 25. A gear 27 meshes with the gear 26. A crushing roller 28 is fixedly connected to the outside of the gear 27. A rotating disk 29 is fixedly connected to the outer end of the rotating disk 29 away from gear 27. A connecting belt 210 is driven to the outer end of the rotating disk 29. A rotating disk 211 is driven to the outer end of the connecting belt 210 away from the rotating disk 29. A tilting conveyor assembly is provided on the outer side of the rotating disk 211. The tilting conveyor assembly includes a spiral blade 212, which is fixedly connected to the outer side of the rotating disk 211. A stirring scraper 213 is fixedly connected to the outer side of the spiral blade 212. A funnel 214 is fixedly connected to the top of the discharge pipe 22. By pouring the fertilizer to be dried into the discharge pipe 22 through the funnel 214, the motor 24 drives... The gear 26 outside the moving crushing roller 25 rotates, causing the gear 26 to drive the crushing roller 28 outside the gear 27 to rotate simultaneously with the crushing roller 25, thereby crushing the agglomerated raw materials. At the same time, the crushing roller 28 drives the rotating disk 29 to rotate, causing the rotating disk 29 to drive the connecting belt 210 to rotate outside the rotating disk 211, causing the spiral blade 212 to rotate simultaneously with the crushing roller 28. The spiral blade 212 carries the crushed fertilizer into the interior of the drying drum 23. The spiral blade 212 also drives the stirring scraper 213 to rotate, causing the stirring scraper 213 to break up the raw materials inside the drying drum 23 for drying.

[0022] Please see Figure 2-3 In this embodiment, when the first rotating disk 29 rotates, the connecting belt 210 drives the second rotating disk 211 to rotate simultaneously. The connecting belt 210 facilitates the simultaneous rotation of the second rotating disk 211 and the first rotating disk 29. A through hole 1 is provided on the discharge pipe 22, and the first rotating disk 29 is rotatably connected to the inside of the discharge pipe 22 through the through hole 1. The discharge pipe 22 facilitates the provision of an installation base for other components.

[0023] Please see Figure 4-5In this embodiment, the screening assembly includes a screening box 31, which is fixedly connected to the outside of the base plate 1. A mounting frame 32 is fixedly connected to the outside of the screening box 31, and a second motor 33 is fixedly connected to the outside of the mounting frame 32. A double-headed cam 34 is fixedly connected to the output end of the second motor 33. A fixed base 35 is fixedly connected to the outside of the screening box 31, and a sliding rod 36 is slidably connected inside the fixed base 35. A connecting plate 37 is fixedly connected to the outside of the sliding rod 36, and a first screen 38 is fixedly connected to the outside of the connecting plate 37. A second screen 39 is fixedly connected to the outside of the connecting plate 37 away from the first screen 38. A sliding rod 312 is fixedly connected inside the screening box 31. A spring 311 is installed at the middle position between the outside of the screen and the inside of the screening box 31. A discharge plate 310 is fixedly connected inside the screening box 31. The presence of a motor 33 facilitates the rotation of the double-headed cam 34. A sliding groove is provided on the screening box 31, and a screen 38 is slidably connected inside the screening box 31 through the sliding groove. The presence of the screen 38 facilitates the screening of fertilizer in conjunction with the screen 39. When the double-headed cam 34 approaches the sliding rod 36, the sliding rod 36 moves downward. When the double-headed cam 34 moves away from the sliding rod 36, the sliding rod 36 slides downward. The presence of the double-headed cam 34 facilitates the reciprocating up-and-down movement of the sliding rod 36.

[0024] During operation, the fertilizer to be dried is poured into the discharge pipe 22 through the funnel 214. At this time, the motor 24 drives the gear 26 outside the crushing roller 25 to rotate, which in turn drives the crushing roller 28 outside the gear 27 to rotate simultaneously with the crushing roller 25, thereby crushing the agglomerated raw material. Simultaneously, the crushing roller 28 drives the rotating disk 29 to rotate, which in turn drives the connecting belt 210 to rotate outside the rotating disk 211, causing the spiral blades 212 to rotate simultaneously with the crushing roller 28. The spiral blades 212 carry the crushed fertilizer into the drying drum 23. The stirring scraper 213 is rotated, causing it to break up the raw materials inside the drying drum 23 for drying. The continuous rotation of the stirring scraper 213 carries the dried fertilizer to the top of the screen 38. The double-headed cam 34 is rotated by the motor 33, causing the sliding rod 36 inside the fixed seat 35 to move away from or towards the sliding rod 36. This causes the sliding rod 36 to move up and down repeatedly, which in turn causes the screens 38 and 39 outside the connecting plate 37 to vibrate in conjunction with the spring 311, thus allowing the screens 38 and 39 to screen the fertilizer.

[0025] Through the above steps, gear meshing drives gear 27 and crushing roller 28 to rotate synchronously, achieving initial crushing of agglomerated raw materials. The rotation of crushing roller 28 synchronously drives rotating disk 29, which in turn transmits power to rotating disk 211 via connecting belt 210, causing the spiral blades 212 to rotate. The spiral blades 212 convey the crushed raw materials to drying drum 23 and simultaneously rotate the stirring scraper 213, improving drying uniformity through stirring. This design effectively prevents agglomeration from affecting subsequent drying results, ensuring production quality.
