Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a fertilizer granule screening device. Background Technology

[0002] Chemical fertilizers, or fertilizers for short, are fertilizers made by chemical or physical methods that contain one or more nutrients needed for crop growth. They are also one of the most important fertilizers in modern crop cultivation.

[0003] In the production process, raw materials are first prepared, and then natural gas, coal, or oil is catalytically converted into synthetic ammonia. The finished fertilizer is then obtained through granulation, screening, and packaging. In Hegang, fertilizer particle screening is a crucial step in chemical production, achieved using a chemical particle coarse and fine screening machine. This machine plays a vital role in chemical production, screening the finished fertilizer based on particle size, relying on screen aperture and vibration or rotation. Existing screening equipment generally uses vibration, which, while capable of screening, has a low capacity, affecting screening efficiency. Therefore, we designed a drum-type fertilizer screening device that can be combined with feeding equipment to achieve integrated screening, guiding, and feeding. Utility Model Content

[0004] In view of the technical problems existing in the background art, this utility model provides a fertilizer granule screening device that can realize automatic screening and is combined with a feeding device to realize the integration of screening, guiding and feeding.

[0006] A fertilizer granule screening device includes a base, a fixed support column, a platform, a feed chute, and a screening mechanism. The upper part of the base is connected to the platform via the fixed support column to form a rectangular frame structure, and the screening mechanism is provided on the upper part of the platform.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] like Figures 1-5 As shown, a fertilizer granule screening device includes a base 1, a fixed support column 2, a platform 3, a feed trough 4, and a screening mechanism 5. The upper part of the base 1 is connected to the platform 3 via the fixed support column 2 to form a rectangular frame structure, and the screening mechanism 5 is provided on the upper part of the platform 3. The screening mechanism 5 includes a receiving group, a rotating drum 504, a connecting bracket 514, a first drive motor 508, and a feed trough 506. The rotating drum 504 is connected to the receiving group on the platform 3 via the built-in connecting bracket 514. A first fixed bracket 505 is provided at one end of the platform 3, and a feed trough 506 is provided on the first fixed bracket 505. A second fixed bracket 507 is provided at the other end of the platform 3, and a first drive motor 508 is provided on the second fixed bracket 507. The rotating drum 504 is a cylindrical cavity structure with openings at both ends, and a plurality of sieve holes are provided on the upper part of the rotating drum 504, with the inner diameter of the sieve holes increasing sequentially from right to left.

[0024] It should be noted that in the fertilizer production process, after granulation and drying, each fertilizer particle is of a different size. In order to meet quality requirements, it is necessary to screen them to separate the finer fertilizer particles for batch storage. However, existing screening equipment generally uses vibrating screening, which is not very efficient and cannot be used for batch storage. Based on this, we have designed a screening device with higher efficiency and the ability to automatically guide, collect, and feed materials, thereby improving the practicality of the equipment.

[0025] It should be further explained that we designed a screening mechanism 5. The entire rotating drum 504 is set on the platform 3 through the receiving group, and a first drive motor 508 is set on one side of the platform 3. Its output shaft is connected to the connecting bracket 514 inside the rotating drum 504. Under the drive of the first drive motor 508, the drum rotates and the fertilizer is screened during the rotation process.

[0026] It should be further explained that, in order to screen fertilizers of different sizes, the inner diameter of the screen holes on the outer wall of the rotating drum 504 increases sequentially from right to left. The entire rotating drum 504 is inclined on the receiving group. During the fertilizer passing process, the fertilizer can fall from the screen holes according to its diameter and be collected through the lower feed trough 509.

[0027] like Figures 1-5 As shown, the receiving assembly includes a first connecting support 501, a second connecting support 503, and a third connecting rod. The third connecting rod is movably connected to the inner cavity of the first connecting support 501 through the second connecting supports 503 on both sides, and the first connecting support 501 is provided with a limiting hole 502 and a limiting pin.

[0028] It should be noted that the receiving group is designed to adjust the height of the entire rotating drum 504, and is designed to connect to conveying equipment of different heights. In use, the height can be adjusted by adjusting the height of the second connecting support column 503 and fixed by the limit pin.

[0029] like Figures 1-5 As shown, a rectangular opening 510 is provided on the upper part of the platform 3, and several feeding troughs 509 are provided inside the rectangular opening 510. The upper part of the feeding trough 509 is respectively provided with the first screening part 511, the second screening part 512 and the third screening part 513 of the rotating drum 504. The lower part of the feeding trough 509 is connected to the guide pipe.

[0030] It should be noted that, in order to accommodate the screening of the upper rotating drum 504, we designed multiple feeding troughs 509 in the rectangular opening 510, which are used to receive the first screening section 511, the second screening section 512 and the third screening section 513 of the rotating drum 504, respectively, to collect the screened fertilizer and guide it into the lower guide trough 4 for transfer.

[0031] like Figures 1-4 As shown, a guide trough 4 is provided on the upper part of the base 1, and a conveyor belt 10 is provided inside the guide trough 4. A second drive motor 11 is provided on one side of the guide trough 4. The output shaft of the first drive motor 508 is connected to the connecting bracket 514 through a coupling.

[0032] It should be noted that the guide chute 4 is designed to facilitate the transportation of fertilizer. Inside the guide chute 4, a conveyor belt 10 is designed, and multiple collection troughs can be placed on the upper part of the conveyor belt 10 to collect the fertilizer discharged from the upper discharge chute 509 and move it under the drive of the conveyor belt 10.

[0033] like Figure 1 and Figure 2 As shown, the bottom of the base 1 is provided with a rotating wheel 6 and a limiting mechanism; the limiting mechanism includes a connecting through hole 7, a screw 8 and a fixing plate 9. The screw 8 is set in the connecting through hole 7 of the base 1, and a fixing plate 9 is provided at one end of the screw 8.

[0034] It should be noted that the bottom of the base 1 is equipped with a rotating wheel 6 and a limiting mechanism. The rotating wheel 6 facilitates the movement of the entire equipment by the operator in conjunction with the trolley, while the limiting mechanism is designed to fix the entire equipment and prevent it from shifting due to vibration during operation. When hauling is required, the screw 8 can be retracted and connected to the trolley to realize hauling, which is convenient for the operator to use.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
