Technical Field

[0001] The utility model belongs to the technical field of organic fertilizer production equipment, in particular to an organic fertilizer particle cooling and screening device. Background Art

[0002] Organic fertilizers contain a variety of nutrients essential for plant growth and are easily absorbed by plants. They also help improve soil structure and enhance crop quality. They play a vital role in improving soil quality, increasing crop yields and quality, and protecting the environment, making them a crucial component of sustainable modern agriculture.

[0003] In the organic fertilizer production process, organic fertilizer undergoes fermentation, drying, cooling and screening. The existing cooling process is to discharge the dried organic fertilizer, wait for it to cool naturally, and then introduce the cooled organic fertilizer into the screening machine for screening. During this period, the organic fertilizer is transferred multiple times, which is not conducive to the production efficiency of organic fertilizer. In addition, during the natural cooling process, the air fluidity in the gaps between the organic fertilizer particles is poor, resulting in a long cooling time. Based on this, we propose an efficient cooling and screening device for organic fertilizer particles. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Reference Figures 1-8 A cooling and screening device for organic fertilizer particles includes a base 100, a screen drum 200, a cover shell 300 and an air supply device 400. The screen drum 200 is penetrated by a rotating shaft 204, and the screen drum 200 is provided with a material guide door. The material guide door opens and closes to facilitate the entry and exit of organic fertilizer into the screen drum 200. The curved side wall of the screen drum 200 is evenly distributed with sieve holes 201. The axial end of the screen drum 200 is provided with an annular baffle 202. The rotating shaft 204 at both ends of the screen drum 200 is sleeved. The sleeve and the annular baffle 202 are provided with connecting rods 203. Fan-shaped ventilation holes 208 are formed between adjacent connecting rods 203. Both ends of the rotating shaft 204 are rotatably connected to the base 100. One end of the rotating shaft 204 is connected to an electric drive. The machine 205 and the motor 205 are arranged on one side of the base 100. The motor 205 is used to drive the rotating shaft 204 to rotate, thereby driving the screen drum 200 to rotate and screen the organic fertilizer. The cover shell 300 is sleeved on the outer side of the arc-shaped side wall of the screen drum 200. The cover shell 300 is composed of two parts. The two-part cover shell 300 is detachably connected. The detachable connection method can be bolted or other connection methods that are easy to disassemble. The air outlet of the air supply device 400 is arranged at one end of the screen drum 200. The air supply device 400 can select a fan. The air supply device 400 cooperates with the cover shell 300. The air enters along the fan-shaped ventilation holes 208 at one end of the screen drum 200 and is discharged from the fan-shaped ventilation holes 208 at the other end. The rotation of the screen drum 200 is beneficial to the air circulation between the organic fertilizers, so that the organic fertilizers are quickly cooled.

[0027] In order to prevent the cover shell 300 from sliding relative to the screen drum 200 and causing wear on the curved side walls of the screen drum 200, a limiting protrusion 207 is provided on the curved side walls of the screen drum 200. Correspondingly, the cover shell 300 is provided with a limiting groove 301. The limiting protrusion 207 and the limiting groove 301 are matched in a concave-convex manner, which is conducive to the rapid installation of the cover shell 300. The cover shell 300 can rotate with the screen drum 200.

[0028] After the organic fertilizer is cooled, the cover 300 can be removed, and the motor 205 drives the screen drum 200 to rotate and screen the organic fertilizer. The base 100 is provided with a receiving box 102, and the screened organic fertilizer falls into the receiving box 102 located below the screen drum 200. Specifically, the base 100 is provided with a recessed portion 101, which is used to embed the receiving box 102. A pulley is provided at the bottom of the receiving box 102 to facilitate the movement of the receiving box 102.

[0029] In one embodiment, a partition 206 is provided along the axial direction of the inner wall of the sieve drum 200, and the partition 206 is vertically connected to the inner wall of the sieve drum 200. A plurality of partitions 206 are evenly arranged along the circumference of the curved side wall of the sieve drum 200. When the sieve drum 200 rotates, the partition 206 cooperates with the inner wall of the sieve drum 200 to lift the organic fertilizer to a certain height, and then the organic fertilizer slides along the edge of the partition 206. During the cooling process, air supplied along the axial direction of the sieve drum 200 can fully contact the organic fertilizer, which is conducive to rapid cooling of the organic fertilizer.

[0030] In one embodiment, the air supply device 400 is an air cooler to improve the cooling efficiency of the organic fertilizer.

[0031] In one embodiment, a cover 209 is provided at one end of the screen drum 200, and the cover 209 is used to cover each fan-shaped ventilation hole 208. The cover 209 is sleeved on the rotating shaft 204, and the cover 209 is provided with an annular plate 210, which is wrapped around the rotating shaft 204. The annular plate 210 rotates with the cover 209, and the annular plate 210 is provided with a joint 211, which is used to connect the air cooler. The base 100 is provided with a limit plate 103, and the limit plate 103 is detachably connected to the joint 211. The detachable connection can be selected from bolt connection or clamping. The limit plate 103 is used to limit the joint 211 to prevent the joint 211 from rotating with the screen drum 200, so that the air cooler can supply air to the screen drum 200 through the pipeline.

[0032] In the cooling process, first, the organic fertilizer is introduced into the sieve drum 200, and then the cover 300 is quickly installed to the outside of the sieve drum 200 by utilizing the concave-convex fit of the limiting protrusion 207 and the limiting groove 301. Then, the limiting plate 103 and the air cooler are respectively connected to the joint 211, and the motor 205 and the air cooler are started. The motor 205 drives the sieve drum 200 to rotate through the rotating shaft 204. In the sieve drum 200, the organic fertilizer is lifted to a certain height along with the partition 206 and then falls. At the same time, the cold air moves from one end of the sieve drum 200 to the other end. The cold air fully contacts and exchanges heat with the falling organic fertilizer, so that the organic fertilizer is quickly cooled.

[0033] During the screening process, the cover 300 is disassembled, and the air cooler and the limit plate 103 are separated from the joint 211. The motor 205 is started, and the motor 205 drives the screen drum 200 to rotate through the rotating shaft 204. The organic fertilizer falls along the sieve hole 201 to the material receiving box 102 located below the screen drum 200, thereby completing the screening of the organic fertilizer.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
