Technical Field
[0001] This utility model relates to the field of organic fertilizer processing technology, and in particular to an organic fertilizer screen. Background Technology
[0002] In modern organic fertilizer production, efficient and precise screening plays a decisive role in the quality of the final product and production efficiency. Among these processes, the screen, as the core component of the screening equipment, directly determines the stability of the equipment's operation, the reliability of screening accuracy, and its adaptability to complex raw materials through its rational structural design and attention to detail. The design must be meticulous to ensure that the screen consistently provides efficient separation in the production environment where organic fertilizer raw materials generally exhibit significant particle size variations. Especially when pursuing high throughput and low clogging rates, the scientific nature of the screen structure and the appropriateness of material selection become particularly important.
[0003] High-performance organic fertilizer screens typically consist of three interconnected parts: a drive mechanism, a screening unit (mesh surface), and a reinforced support frame. The drive mechanism is the power source for the screen's efficient operation, its core function being to provide stable, adjustable excitation force and a reasonable motion trajectory. Precise dynamic design ensures that energy is evenly and effectively transferred to the entire screen surface, promoting rapid stratification, screening, and forward conveying of materials on the mesh, thereby maximizing screening efficiency and effectively preventing material accumulation and clogging. This optimized vibration characteristic is crucial for maintaining smooth production, especially when processing organic fertilizers with high moisture content or fibrous content. The screening unit (mesh surface), as the core functional carrier of the screen, is usually precision-manufactured using high-strength, highly wear-resistant, and corrosion-resistant special materials. Its mesh structure is precisely calculated and optimized to ensure clear and durable screening accuracy and excellent durability even under continuous impact, friction, and chemical corrosion, effectively separating organic fertilizer particles that meet specifications. The reinforced support frame provides a robust and stable foundation for the entire screen. It is typically welded from heavy steel or profiles, possessing extremely high rigidity and fatigue resistance. Its core function is to firmly support the vibration mechanism and screening unit, ensuring that the entire screen does not deform, break, or loosen under high-intensity, long-term continuous operation, thereby guaranteeing the smooth operation of the screening process and the long-term consistency of screening accuracy, and avoiding performance degradation or equipment failure due to structural failure.
[0004] The work environment is polluted. Organic fertilizer dust (containing microorganisms, ammonia, and dust particles) diffuses into the operating area, exceeding occupational health exposure limits. This increases equipment failure rates, and dust intrudes into drive bearings and vibration motor windings, accelerating wear on precision components and causing electrical short circuits. Raw material loss is out of control, and fine organic fertilizer powder of acceptable particle size escapes with the airflow, resulting in a decrease in finished product yield. Existing technologies cannot effectively isolate the dynamic dust generated during screening, and the open structure of the screen makes it difficult to achieve a complete seal for dust removal. This structural defect is the fundamental bottleneck restricting the safety of the production environment and the reliability of equipment. Therefore, an organic fertilizer screen is proposed to solve the above problems. Utility Model Content

The feed inlet 10 is fixed at the feed end of the screening screen 8. The measured amount of organic fertilizer enters the screening screen 8 through the feed inlet 10. The motor 7 drives the screen support 6 and thus drives the screening screen 8 to rotate, screening the organic fertilizer entering the screening screen 8. The screening screen 8 has a certain angle with the horizontal plane, which facilitates the collection of organic fertilizer after screening. Organic fertilizer larger than the aperture of the screening screen 8 will enter the collection box 28 through the gap between the baffle 5 and the support 3. Organic fertilizer smaller than the aperture of the screening screen 8 will enter the collection box 27 through the hole under the support 3.

When the equipment stops running, in order to prevent residual organic fertilizer in the equipment, the rear end of hydraulic cylinder 9 is connected to base 1, and the front end of hydraulic cylinder 9 is connected to support base 3. Starting hydraulic cylinder 9 raises the height of the feeding end of the equipment, increases the inclination angle of screening screen 8 to the horizontal plane, and pours out the residual organic fertilizer. For easy cleaning, a structure for lifting dust cover 21 is designed. Reciprocating frame 22 is fixed on base 1 to provide directional guidance for reciprocating frame 20. Motor 3 16 starts and drives turntable 17 to rotate. Turntable 17 drives support column 2 18 to rotate. Support column 2 18 drives sliding groove 19 to rise. Sliding groove 19 is fixedly connected to reciprocating frame 20. Reciprocating frame 20 is fixedly connected to dust cover 21, thereby driving dust cover 21 to rise, which facilitates cleaning of the equipment.
