Description

Technical Field

[0001] This utility model relates to the field of granulation equipment, and in particular to a simple microbial fertilizer granulation device. Background Technology

[0002] Microbial fertilizers, as a new type of green fertilizer, have been widely used in recent years due to their advantages such as improving soil fertility, promoting crop growth, and reducing the use of chemical fertilizers. Granulation is a key process in the production of microbial fertilizers, directly affecting the fertilizer's particle strength, solubility, storage stability, and other properties.

[0003] In the research and development of microbial fertilizers, small-batch granulation experiments are required to verify the feasibility of the formula and process or to obtain granule samples with different indicators. However, existing granulation equipment is mostly designed for large-scale production and uses extrusion or rolling granulation, which has problems such as poor particle uniformity, low yield, high temperature granulation process that can easily destroy microbial activity, complex equipment structure, high energy consumption and strict requirements on material moisture content, difficult equipment cleaning, and residual material that can easily lead to cross-contamination, resulting in a waste of manpower and resources. Manual granulation is also difficult and therefore not suitable for laboratory use. Utility Model Content

[0035] 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.

[0036] Example 1

[0037] This utility model provides, for example Figure 1-2 The illustrated simple microbial fertilizer granulation device includes a base 1, a granulation cylinder 2, a fixed cylinder 3, a rotary granulation mechanism 4, a spraying mechanism 5, and a filtration mechanism 6. The granulation cylinder 2 is fixedly connected to the top of the base 1, and the fixed cylinder 3 is fixedly connected to the top of the inner wall of the granulation cylinder 2. The rotary granulation mechanism 4 is located inside the fixed cylinder 3. The spraying mechanism 5 is located on the fixed cylinder 3 and is used to spray adhesive onto the material. The filtration mechanism 6 is located inside the granulation cylinder 2 and is used to remove unqualified particles. Through the action of the rotary granulation mechanism 4 and the spraying mechanism 5, particles of uniform size and moderate strength can be produced. By adjusting parameters such as rotation speed and spray volume, different experimental needs can be met. The overall structure is simple, easy to operate and maintain, and suitable for laboratory use. At the same time, the simple design reduces manufacturing costs and is suitable for laboratory budgets. Furthermore, the filtration mechanism 6 can screen out unqualified materials, facilitating secondary processing and saving resources.

[0038] The rotary granulation mechanism 4 includes a motor 41, a gearbox 42, a rotating rod 43, a spiral blade 44, and protrusions 45. The motor 41 is fixedly installed inside the base 1, and the gearbox 42 is also fixedly installed inside the base 1. The output end of the motor 41 is connected to the input end of the gearbox 42. The rotating rod 43 is connected to the output end of the gearbox 42. The spiral blade 44 is rotatably disposed inside the fixed cylinder 3. The rotating rod 43 is fixedly connected to the spiral blade 44. The protrusions 45 are equidistantly fixed to the top of the spiral blade 44. The cross-section of the protrusions 45 is semi-circular. The motor 41 is connected to the base 1 via an external switch. An external power supply is electrically connected, and the motor 41 and gearbox 42 can drive the spiral blades 44 connected to the rotating rod 43 to rotate slowly inside the fixed cylinder 3. This allows the material added to the top of the granulation cylinder 2 to effectively increase the residence time of the material on the blade surface through the interference of the spiral inclined surface and the protrusions 45. This allows the material to fully absorb moisture or other adhesives under the action of the spraying mechanism 5, thereby promoting the formation of granules. The uniform distribution of each protrusion 45 ensures that the material is subjected to appropriate compression and disturbance when passing through, further increasing the uniformity and density of the granules.

[0039] Example 2

[0040] Based on Example 1, such as Figure 3-4 As shown, the spraying mechanism 5 includes a spray pipe 51 and a spray head 52. The spray pipe 51 is fixedly installed on the inner wall of the fixed cylinder 3, and the spray head 52 is fixedly connected at equal intervals to the bottom end of the spray pipe 51. The spray pipe 51 is connected to an external pump body, which can spray external adhesive evenly onto the material on the spiral blade 44 through multiple spray heads 52 to promote particle formation.

[0041] The filtration mechanism 6 includes a filter box 61, a filter plate 62, a recovery box 63, and a guide plate 64. The filter box 61 is fixedly connected to the bottom end of the inner wall of the granulation cylinder 2 and is used to receive particles pushed down by the rotating spiral blades 44 inside the fixed cylinder 3. The filter plate 62 is fixedly installed inside the filter box 61 and is inclined. The recovery box 63 passes through the granulation cylinder 2 and is slidably inserted into the inner cavity of the filter box 61 to receive unqualified particles. The guide plate 64 is fixedly connected to the inner wall of the filter box 61, and a guide groove is opened in the middle of the guide plate 64. The opening at the top is located below the feed inlet of the fixed cylinder 3, allowing the formed granules and some defective granules to fall directly onto the filter plate 62 inside the filter box 61. The inclined filter plate 62 not only filters the granules, allowing qualified granules to be discharged through the feed pipe 7, but also guides smaller, unqualified granules into the recycling box 63 under the guidance of the guide plate 64. These smaller, unqualified granules can then be reprocessed and fed back into the rotary granulation mechanism 4 for further processing to form qualified granules. This process not only improves the utilization rate of raw materials but also reduces production costs.

[0042] Furthermore, a feed pipe 7 is fixedly connected to one side of the granulation cylinder 2. The feed pipe 7 is fixedly interlocked with the filter box 61, and the qualified granular material filtered out will be discharged through the feed pipe 7.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
