Description

Technical Field

[0001] The present invention belongs to the field of devices for granulating organic fertilizers, and in particular, relates to a mineral source organic fertilizer granulator and a using method thereof. Background Art

[0002] The main purpose of fertilizer granulation is to improve the fluidity, applicability, and storage stability of fertilizers, reduce dust and waste, and facilitate transportation and application. Granulation methods are mainly divided into physical granulation, chemical granulation, wet granulation, etc. Among them, physical granulation includes methods such as roll pressing and wheel rolling, and different methods are suitable for different types of fertilizer production.

[0003] In the existing wheel rolling granulation, a semi-circular groove is directly formed on the surface of the roller. During granulation, relevant workers transport the materials (fertilizer and binder) into the box body, and the motor drives two granulation rollers to rotate. The corresponding semi-circular grooves on the two granulation rollers abut against each other, and the materials are extruded into the semi-circular grooves, thereby extruding fertilizer particles at one time. However, after the materials are extruded and formed, there will be a situation where some materials adhere in the semi-circular grooves (such as the humidity of the materials themselves causing adhesion or the roughness of the semi-circular grooves causing adhesion, etc.). Therefore, during the next extrusion, the remaining materials will affect the granulation quality of the fertilizers.

[0004] At the same time, the existing wheel rolling granulation can only perform granulation operations. Workers need to mix the materials (fertilizer or fertilizer and binder) and then transport them into the box body. The above method is time-consuming and laborious. At the same time, it is difficult to ensure that the produced fertilizer particles meet the use standards during the granulation process. A large amount of debris is also mixed in the fertilizer particles, making it difficult to ensure the product quality of the fertilizer particles. Moreover, the water content of the fertilizer after granulation cannot meet the required standard, and it lacks a drying function. Summary of the Invention

[0020] The present invention provides a mineral source organic fertilizer granulator, which can solve the problems raised in the background technology: In the existing rotary granulation, a semi-circular groove is directly formed on the surface of the roller. During granulation, relevant staff transport the material (fertilizer or fertilizer and binder) into the box body, and the motor drives the two granulating rollers to rotate. The corresponding semi-circular grooves on the two granulating rollers abut against each other, and the material is extruded into the semi-circular grooves, thereby extruding the fertilizer particles at one time. However, after the material is extruded and formed, there will be a situation where some material adheres in the semi-circular grooves (such as the humidity of the material itself causing adhesion or the roughness of the semi-circular grooves causing adhesion, etc.). Therefore, during the next extrusion, the remaining material will affect the granulation quality of the fertilizer.

[0021] In addition, the existing roller granulation can only perform granulation operations. Workers need to mix materials (fertilizer and binder) and then transport them into the box. The above method is time-consuming and laborious. It can also solve the problem that it is difficult to ensure that the produced fertilizer particles meet the usage standards during the granulation process. There are also a large number of debris mixed in the fertilizer particles, making it difficult to ensure the quality of the fertilizer particle products. And the water content of the fertilizer after granulation cannot meet the compliance standards, lacking a drying function. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A method for using a mineral source organic fertilizer granulator, the method comprising the following steps:

[0035] S1: Add fertilizer raw materials and a binder through the mixing box feed inlet 1-3, and start the first motor 1-4-4 to mix the fertilizer raw materials and the binder;

[0036] S2: Press down the slide plate 1-4-3 to make the upper friction plate 1-4-7 contact and abut against the lower friction plate 1-5-2 to drive the spiral blade 1-5-3 to rotate for feeding;

[0037] S3: Drive the two granulating rollers 2-1 to rotate in reverse synchronously by the second motor 2-2 to extrude and form the fertilizer into particles;

[0038] S4: Energize the third motor 3-3 to rotate the baffle 3-5 to disperse the particles and clean the debris. The working principle of the present invention is:

[0039] Check the equipment status: Confirm that the inspection operation door of the housing assembly 1 is closed, there is no residual material in the semi-circular grooves on the surface of the granulating roller 2-1, the brush 2-5 is in good contact with the roller, and the filter screen 3-6 of the screening box 3-1 is not blocked.

[0040] Raw material mixing: Add fertilizer raw materials and a binder through the mixing box feed inlet 1-3 provided in the mixing box 1-2, and start the first motor 1-4-4 to drive the stirring shaft 1-4-5 to drive the stirring rod 1-4-6 to mix the fertilizer raw materials and the binder, which can solve the problem that it is time-consuming and laborious for workers to mix the materials (fertilizer and binder) and then transport them into the box.

[0041] Feeding: The spiral blade 1-5-3 abuts against the inner wall of the discharge port 1-6 of the mixing box. When the stirring shaft 1-4-5 rotates during stirring, the spiral blade 1-5-3 does not rotate, thus blocking the fertilizer. During feeding, the slide plate 1-4-3 is pressed downward and slides downward along the guide post 1-4-1, while compressing the first spring 1-4-2. The first spring 1-4-2 functions to reset the slide plate 1-4-3. When the slide plate 1-4-3 moves downward, it drives the stirring shaft 1-4-5 to move downward through the first motor 1-4-4, so that the upper friction plate 1-4-7 contacts and abuts against the lower friction plate 1-5-2. At the same time, through frictional transmission, the feeding shaft 1-5-1 is driven to rotate. The rotation of the feeding shaft 1-5-1 drives the spiral blade 1-5-3 to rotate. The rotation of the spiral blade 1-5-3 drives the mixed fertilizer to move downward and fall at the gap between the granulating rollers 2-1. The second motor 2-2 is powered on to drive the two granulating rollers 2-1 to rotate in reverse synchronously. At the same time, the semi-circular grooves on the surfaces of the two granulating rollers 2-1 are engaged to extrude the fertilizer into particles. When the granulating rollers 2-1 rotate, the second spring 2-3-1 fixed to the end face drives the contact column 2-3-2 to periodically strike the limit rod 2-4, generating high-frequency vibration, which prompts the adhering materials to fall off from the grooves. At the same time, the brush 2-5 synchronously cleans the residues on the surface of the granulating rollers 2-1 and in the semi-circular grooves. Through the double cleaning of the threshing mechanism 2-3 and the brush 2-5, the problem that the remaining materials will affect the granulation quality of the fertilizer can be avoided.

[0042] The granulated fertilizer enters the screening box 3-1 through the feeding port 3-2 of the screening box. The third motor 3-3 is powered on, and the dial 3-5 is driven to rotate by the screening shaft 3-4 to disperse the particles. At the same time, the debris mixed in the particles falls into the collection tank 3-7 through the filter screen 3-6 for collection. The dryer 3-8 is an existing technology and is purchased externally, so it will not be elaborated here. The dryer 3-8 is powered on to deliver hot air into the screening box 3-1, which can dry the particles, and thus the moisture content of the particles can be adjusted. Finally, the finished product can be taken out through the discharge port of the screening box.
