Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, specifically to a bio-organic fertilizer granulator. Background Technology

[0002] Bio-organic fertilizer is made from organic waste such as livestock and poultry manure, straw, and kitchen waste, which is fermented and decomposed to improve soil and enhance crop quality. However, since the fermented organic raw materials are mostly in powder or loose clumps, they present problems such as inconvenient transportation, dust generation during application, and uneven nutrient release. Therefore, they need to be granulated into granular products.

[0003] Granulators are the core equipment in the production of bio-organic fertilizers, and their performance directly affects the uniformity, strength, and production efficiency of the granules. Among various granulation technologies, drum granulators have become the mainstream choice for small and medium-sized production enterprises due to their simple structure, low energy consumption, and strong adaptability.

[0004] The drum of the rotary granulator is tilted and rotated under the drive of a motor. The material inside the drum is subjected to the combined action of gravity, centrifugal force and friction, and moves in a spiral upward and downward motion along the drum wall. Small particles collide with each other during the rolling and are bonded together by the adsorption force of the surface liquid film to form "core particles". The core particles continue to roll and continuously adsorb surrounding powder to gradually grow and form particles with a particle size of 2-8mm, thus realizing granulation.

[0005] In existing technologies, humidity cannot be regulated during granulation, and granules are often discharged along with unformed materials, affecting the quality of fertilizer granules. Utility Model Content

[0006] In order to solve the technical problem that the humidity cannot be adjusted during the granulation process and the granules are often discharged along with unformed materials, which affects the quality of fertilizer granules, this utility model provides a biological organic fertilizer granulator.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a biological organic fertilizer granulator, comprising: a spray cylinder, the end of which is rotatably connected to and communicates with one end of a bend, the other end of which is rotatably connected to and communicates with the end of a granulation cylinder, the other end of which is rotatably connected to and communicates with the end of a second bend, and the other end of the second bend is rotatably connected to and communicates with the end of a discharge screen cylinder. The axes of the spray cylinder, granulation cylinder, and discharge screen cylinder have different downward inclination angles. The spray cylinder, granulation cylinder, and discharge screen cylinder are rotatably connected within a frame. The spray cylinder, granulation cylinder, and discharge screen cylinder are connected to different power sources. A spraying mechanism is provided on the upper part of the spray cylinder, and the spraying mechanism is connected to the first bend. Multiple lifting plates are evenly distributed around the inner circumference of the granulation cylinder.

[0008] Preferably, the spraying mechanism includes a liquid injection pipe connected to an elbow and connected to the discharge end of a liquid pump. The axis of the liquid injection pipe is located above the axis of the spray cylinder and is arranged parallel to it. A nozzle is connected to the lower part of the liquid injection pipe inside the spray cylinder.

[0009] Preferably, the granulation cylinder is located below the spray cylinder, and the discharge screen cylinder is located on one side of the granulation cylinder.

[0010] Preferably, the height of the lifting plate gradually decreases until it reaches zero along the inclined direction of the granulation cylinder from top to bottom.

[0011] Preferably, the outer surfaces of the spray cylinder, granulation cylinder, and discharge screen cylinder are all connected to input gears, and each input gear is meshed with the output gear of the corresponding motor.

[0012] Preferably, the spray cylinder axis has an inclination angle of 2-3°, the granulation cylinder axis has an inclination angle of 4-5°, and the discharge screen cylinder axis has an inclination angle of 6-8°.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The dispersed material first enters the rotating spray cylinder, where the spraying mechanism sprays water evenly onto the material from top to bottom to regulate humidity. Then it enters the rotating granulation cylinder, where the material collides and agglomerates under the action of the lifting plates, forming uniform granules. Finally, the rotating discharge screen screens out the unqualified granules and unformed materials, producing fertilizer granules of uniform size with high granulation quality.

[0014] The height of the lifting plate gradually decreases along the inclined direction until it reaches zero, reducing the agitation of the formed particles and effectively preventing the formed particles from being broken up. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-2 This embodiment describes a bio-organic fertilizer granulator, comprising: a spray cylinder 1, one end of which is rotatably connected to and connected to one end of a bend 2; the other end of the bend 2 is rotatably connected to and connected to the end of a granulation cylinder 3; the other end of the granulation cylinder 3 is rotatably connected to and connected to the end of a bend 4; the other end of the bend 4 is rotatably connected to and connected to the end of a discharge screen cylinder 5; the axes of the spray cylinder 1, granulation cylinder 3, and discharge screen cylinder 5 have different downward inclination angles; the spray cylinder 1, granulation cylinder 3, and discharge screen cylinder 5 are rotatably connected within a frame 6; the spray cylinder 1, granulation cylinder 3, and discharge screen cylinder 5 are respectively connected to different power sources; a spraying mechanism 7 is provided on the upper part of the spray cylinder 1, and the spraying mechanism 7 is connected to the bend 2; multiple lifting plates 8 are evenly distributed around the inner circumference of the granulation cylinder 3.

[0021] The dispersed material is injected through the end of the spray cylinder 1. The power drives the spray cylinder 1 to rotate, and the spraying mechanism 7 sprays water evenly from top to bottom onto the rotating material to regulate the humidity. Then, the material enters the rotating granulation cylinder 3 through the elbow 1 2. Under the action of the lifting plate 8, the material collides and agglomerates with each other to form uniform granules. Finally, the granules enter the rotating discharge screen cylinder 5 through the elbow 2 4. The discharge screen cylinder 5 screens out unqualified granules and unformed materials, and qualified granules are discharged from the end of the discharge screen cylinder 5, making fertilizer granules of uniform size with high granulation quality. The elbow 1 2 and elbow 2 4 are fixed by the frame 6 and will not loosen or fall off.

[0022] The spraying mechanism 7 includes a liquid injection pipe 71, which is connected to the elbow 2. The liquid injection pipe 71 is connected to the liquid pump discharge end. The axis of the liquid injection pipe 71 is located above the axis of the spray cylinder 1 and is arranged in parallel. The lower part of the liquid injection pipe 71 inside the spray cylinder 1 is connected to a nozzle 72.

[0023] The liquid pump pumps water into the injection pipe 71, and then sprays it evenly downwards through the nozzle 72 to achieve spraying.

[0024] Granulation cylinder 3 is located below spray cylinder 1, and discharge screen cylinder 5 is located on one side of granulation cylinder 3.

[0025] The material falls into the spray cylinder 1, breaking up large clumps. The material that has formed granules smoothly enters the discharge screen cylinder 5 on one side through the elbow 4, avoiding the granules from breaking.

[0026] As the granulation cylinder 3 tilts downwards along its axis, the height of the lifting plate 8 gradually decreases until it reaches zero.

[0027] The height of the lifting plate 8 at the front end of the granulation cylinder 3 is relatively high, which facilitates the throwing of materials. The height of the lifting plate 8 at the rear end is zero to avoid particle breakage.

[0028] The outer surfaces of the spray cylinder 1, granulation cylinder 3, and discharge screen cylinder 5 are all connected to input gears 9, and each input gear 9 is meshed with the output gear of the corresponding motor.

[0029] The axis of the spray cylinder 1 has an inclination angle of 2-3°, the axis of the granulation cylinder 3 has an inclination angle of 4-5°, and the axis of the discharge screen cylinder has an inclination angle of 6-8°.
