Description

Technical Field

[0001] The utility model relates to the field of biological organic fertilizer processing equipment, in particular to a biological organic fertilizer granulator. Background Art

[0002] The bio-organic fertilizer granulator is environmentally friendly, harmless, simple to operate, and easy to maintain. It can effectively convert organic waste into organic fertilizer, realize the recycling of resources, and reduce environmental pollution. The bio-organic fertilizer granulator evaporates the water in the organic waste, decomposes the cellulose, and denatures the protein through mixing, extrusion, heating, and other processes to form organic granular fertilizer with high biological activity and nutrient content.

[0003] After searching, the publication number CN218795718U discloses a biological organic fertilizer granulator, including a casing, a conveying structure is arranged on the right side of the casing, a granulating structure is arranged outside the casing, the conveying structure includes a belt shell, the left side of the belt shell is fixedly connected to the right side of the casing, a mounting shell is fixedly installed on the right side of the belt shell, a conveying pipe is fixedly installed on the top of the mounting shell, a rotating rod with one end penetrating and extending into the inside of the conveying pipe is rotatably installed on the inner bottom wall of the mounting shell, and a transverse gear is fixedly installed on the outer surface of the rotating rod.

[0004] However, in the actual production process, if the humidity of the biological organic fertilizer is too high, that is, the water content is too high, the granulation process will face a series of challenges.

[0005] Specifically, when the humidity of organic fertilizer is high, its viscosity also increases. After being squeezed by the rollers of the double-roller granulator, the formed organic fertilizer particles are often easily attached to the granulation groove on the roller due to their high viscosity. This adhesion phenomenon not only affects the continuity and stability of subsequent granulation and reduces the granulation efficiency, but may also cause the gap between the rollers to become smaller due to excessive accumulation, and even cause blockage and damage to the rollers, requiring multiple shutdowns to clean the rollers.

When the cleaning head 303 passes through the granulation groove 201, the biological organic fertilizer in the granulation groove 201 can be dug and cleaned under the elastic force of the elastic member 305. As the granulation roller 2 continues to rotate, when the cleaning head 303 is removed from the granulation groove 201, it can always be in contact with the surface of the granulation roller 2 under the elastic force of the elastic member 305.

[0046] Reference Figure 1 and Figure 2 The granulation container 1 includes: two fixing holes 101, which are respectively opened on both sides of the granulation container 1, and two collecting plates 301 are respectively installed in the two fixing holes 101; a feeding port 102 is opened on the top of the granulation container 1, which is used to put the biological organic fertilizer raw materials, and the collecting plates 301 are installed in the fixing holes 101, which facilitates the installation and disassembly of the collecting plates 301 and is conducive to later maintenance; the feeding port 102 makes the feeding process more convenient, and also facilitates the observation and monitoring of the operator.

[0047] Reference Figure 4 and Figure 5The cleaning mechanism 3 also includes: a material guide groove 306, which is opened on the surface of the collecting plate 301, and the connecting plate 302 is installed in the material guide groove 306; a plurality of grooves 304, which are opened on the top of the connecting plate 302, and the cleaning head 303 is installed in the groove 304. The cleaning head 303 is configured to be rotatable in the groove 304 and close to the surface of the granulating roller 2. The side wall of the groove 304 is connected to an elastic member 305, and one end of the elastic member 305 is connected to the cleaning head 303, which is used to provide the cleaning head 303 with an initial position restoring force after rotation. The elastic member 305 adopts a coil spring and can also adopt a clockwork spring.

[0048] Reference Figure 4 and Figure 5 The end of the cleaning head 303 close to the granulating roller 2 is hook-shaped, which matches the shape and size of the granulating tank 201, and can more accurately dig and clean the biological organic fertilizer attached to the granulating tank 201, further improving the cleaning effect.

Through the action of the screening element 105, the biological organic fertilizer particles and excess powder can be separated to obtain a biological organic fertilizer product that meets the requirements.

[0051] During use, the operator puts the bio-organic fertilizer raw material into the granulation container 1 through the feeding port 102 opened on the top of the granulation container 1. The raw material enters the granulation container 1 through the feeding port 102 and is accurately and evenly distributed between the two granulation rollers 2 under the guidance of two inclined and symmetrically arranged guide plates 103. The two power sources 104 installed on the outside of the granulation container 1 start to work, providing the two granulation rollers 2 with power to rotate simultaneously in opposite directions. As the granulation roller 2 rotates, a plurality of granulation grooves 201 formed on its surface begin to contact with the bio-organic fertilizer raw material and uniformly press the raw material into granules. The cleaning head 303 in the cleaning mechanism 3 is in close contact with the surface of the granulation roller 2 in the groove 304 and moves with the rotation of the granulation roller 2. When the cleaning head 303 in the cleaning mechanism 3 is in close contact with the surface of the granulation roller 2, the cleaning head 303 moves with the rotation of the granulation roller 2. When the head 303 passes through the granulation groove 201, under the elastic force of the elastic member 305, the cleaning head 303 digs and cleans the biological organic fertilizer in the granulation groove 201, and the cleaned biological organic fertilizer is collected through the guide groove 306 on the collecting plate 301, thereby avoiding waste of materials and environmental pollution. The collecting plate 301 in the cleaning mechanism 3 is designed to be longer than the length of the granulation roller 2 to ensure that the biological organic fertilizer particles falling from the granulation roller 2 can be completely covered and collected. The collected particles are further guided to the next process through the collecting plate 301, and the screening member 105 screens the biological organic fertilizer particles falling from the granulation roller 2, separates the biological organic fertilizer particles and excess powder, and obtains a biological organic fertilizer product that meets the requirements.

[0052] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0053] By installing the cleaning mechanism 3, the bio-organic fertilizer attached to the granulation tank 201 can be cleaned in real time, avoiding the reduction or blockage of the roller gap caused by material accumulation, ensuring the continuity and stability of the granulation process, and significantly improving the granulation efficiency.

[0054] The automatic cleaning function of the cleaning mechanism 3 reduces the number of times the machine needs to be stopped for manual cleaning due to material adhesion, reduces the downtime of the production line, and reduces maintenance costs.

[0055] The cleaning mechanism 3 can collect the cleaned biological organic fertilizer, thereby avoiding the waste of materials and the pollution of the environment, and reducing the waste of energy, thus meeting the requirements of environmental protection and energy saving.
