Description

Technical Field

[0001] The utility model relates to the technical field of non-drying organic fertilizer granulation, in particular to an extrusion granulation device for non-drying organic fertilizer. Background Technique

[0002] Non-drying organic fertilizer is an organic fertilizer that can be prepared without the traditional drying process. In the production process of this fertilizer, an active substance called non-drying element is added, which can convert the free water in the fertilizer particles into bound water, thereby reducing the amount of free water in the particles after granulation and realizing the granulation preparation process without drying. The production process of non-drying organic fertilizer includes two main steps: fermentation and granulation. Since non-drying organic fertilizer does not require a drying process, it can significantly reduce production costs and energy consumption. It is suitable for fruit and vegetable crops, which can not only improve the quality of crops but also improve the soil. This fertilizer is easy to operate when used and is welcomed by farmers due to its long fertilizer efficiency period.

[0003] When the existing non-drying organic fertilizer is granulated, it is necessary to first preliminarily extrude and granulate to obtain organic fertilizer particles and then send them to a rounding machine. Finally, high-quality spherical organic fertilizer particles are obtained through the rounding machine. There are problems such as low efficiency during preliminary extrusion granulation and easy generation of a large amount of dust, which will pollute the surrounding environment. Therefore, it does not meet the existing requirements, and an extrusion granulation device for non-drying organic fertilizer is proposed for this. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the raw materials of the non-drying organic fertilizer are fed into the granulation cylinder. When the stacking height of the raw materials reaches the set value, the hydraulic cylinder controls the pressing plate to descend. As the pressing plate presses the raw materials inside the granulation cylinder, the raw materials become strip-shaped through the discharge holes.

[0020] In order to solve the problems that the efficiency of the preliminary extrusion granulation of the raw materials of the non-dried organic fertilizer is relatively low, and at the same time, a large amount of dust is easily generated, thereby polluting the surrounding environment, please refer to Figures 1-4 , an embodiment provided by the present utility model: an extrusion granulation device for non-dried organic fertilizer, including a granulation cylinder 1, and further including a transfer chamber 2. The transfer chamber 2 is located below the granulation cylinder 1. The lower end of the granulation cylinder 1 extends into the interior of the transfer chamber 2. A fixing ring 4 is arranged at the upper end of the transfer chamber 2. A bottom plate 204 is arranged at the lower end of the transfer chamber 2. A dust removal pipe 8 and a guiding plate 7 are arranged on the inner wall of the transfer chamber 2. An air permeable plate 9 is arranged above the bottom plate 204. The granulation cylinder 1 is a hollow cylindrical structure. A feed inlet 101 is arranged on the side surface of the granulation cylinder 1. A plurality of discharge holes 102 are arranged at the lower part of the granulation cylinder 1. A pressing plate 303 is arranged inside the granulation cylinder 1. A cutting component 5 is arranged below the granulation cylinder 1.

[0021] Above the granulation cylinder 1, a hydraulic cylinder 3 is provided. The hydraulic cylinder 3 is connected to the granulation cylinder 1 through a bracket 301. The hydraulic cylinder 3 is provided with a telescopic rod 302 at its lower end. The telescopic rod 302 extends into the granulation cylinder 1 and is connected to a pressing plate 303. The cutting component 5 includes a transmission plate 501, a positioning plate 502, and a scraper 503. One end of the positioning plate 502 is connected to the transmission plate 501, the other end of the positioning plate 502 is connected to the scraper 503, and the scraper 503 contacts the outer side surface of the granulation cylinder 1. The transmission plate 501 is a hollow cylindrical structure. A second motor 6 is arranged inside the transmission plate 501. The upper end of the second motor 6 is connected to the granulation cylinder 1, and the lower end of the second motor 6 is shaft-connected to the transmission plate 501. A slider 504 is arranged at the upper end of the scraper 503. A slideway 401 is arranged below the fixed ring 4. The slider 504 is located inside the slideway 401.

[0022] The raw materials of the non-drying organic fertilizer are fed into the interior of the granulation cylinder 1 through the feed inlet 101. When the stacking height of the raw materials reaches the set value, the hydraulic cylinder 3 controls the pressing plate 303 to descend. As the pressing plate 303 squeezes the raw materials inside the granulation cylinder 1, the raw materials become strip-shaped through the discharge holes 102. The second motor 6 drives the cutting component 5 to rotate, so that the rotating scraper 503 cuts the strip-shaped non-drying organic fertilizer raw materials into particles. Compared with the traditional method of continuously pushing the non-drying organic fertilizer raw materials through the discharge holes 102 by a worm, a large number of particles can be produced at one time, further improving the production efficiency.

[0023] The side surface of the dust removal pipe 8 is connected to the inner wall of the transfer chamber 2. One end of the guide plate 7 is connected to the transfer chamber 2.

[0024] After the non-drying organic fertilizer raw materials are preliminarily prepared into particles, they first fall along the guide plate 7 into the interior of the transfer chamber 2 and accumulate on the air-permeable plate 9, and then are rotated and pushed by the discharge plate 202. Finally, they pass through the discharge port 201 into the interior of the rounding machine. When the discharge plate 202 rotates, the fan 901 continuously blows out upward airflows. The airflows pass through the air-permeable plate 9 and drive the dust in the preliminary particles of the non-drying organic fertilizer raw materials to move upward. At this time, the vacuum cleaner is turned on, and the dust is then collected into the external vacuum cleaner through the dust removal pipe 8, thereby reducing the situation of dust overflow, protecting the surrounding environment, and at the same time improving the cleanliness of the working environment and further enhancing the practicality.

[0025] Working principle: By feeding the fermented organic fertilizer raw materials without drying into the interior of the granulating cylinder 1, as the pressing plate 303 presses the organic fertilizer raw materials without drying inside the granulating cylinder 1, the organic fertilizer raw materials without drying become strip-shaped through the discharge holes 102, and then the cutting assembly 5 cuts the strip-shaped organic fertilizer raw materials without drying into granules. The generated dust is collected by the dust removal pipe 8 and then guided to an external vacuum cleaner, improving the production efficiency.
