Description

Technical Field

[0001] This utility model relates to the field of feed additive production and processing technology, and more specifically, it relates to a drying mechanism for feed additive processing. Background Technology

[0002] Drying is a key process in the production and processing of feed additives. Traditional drying equipment usually uses a fixed hot air conveying method, which cannot adjust the air flow rate according to the characteristics and moisture content of different types of feed additives. This single drying method not only leads to uneven drying effect, but may also affect product quality due to excessive or insufficient hot air volume, and even cause energy waste and reduce production efficiency.

[0003] In actual production, different types of feed additives have different requirements for drying conditions. Some additives require a large air flow to quickly remove moisture, while others require a small air flow to maintain product characteristics. However, existing drying equipment often lacks an effective airflow regulation mechanism, and operators cannot accurately control the drying process according to actual needs. This not only affects the drying quality of the product but also increases production costs, failing to meet the requirements of modern production for refined control. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a drying mechanism for processing feed additives, which has the following beneficial effects:

[0017] 1. The drying device uses a motor-driven central shaft to rotate the drying drum. Combined with the design of multiple sets of agitator plates, it achieves full tumbling of materials, ensuring that feed additives are in full contact with hot air. Multiple ventilation holes on the outer wall of the drying drum provide channels for hot air to enter, improving drying efficiency. The design of the heat preservation box maintains the internal temperature, further enhancing the drying effect. The observation window on the box door allows operators to monitor the drying process in real time, improving the convenience and safety of operation. This design not only solves the problem of uneven drying effect in traditional drying equipment, but also improves production efficiency and meets the drying needs of different types of feed additives.

[0018] 2. The regulating device adopts an innovative multi-layer regulating mechanism. By rotating the regulating sleeve, the sliding rod and transmission sleeve move, which in turn pushes the flow control block to slide through the inclined rod, changing the position of the through hole to regulate the hot air flow. The design of the force spring ensures the stability and reliability of the regulation. The cooperation of the limiting plate and the limiting groove prevents the deflection of the flow control block and ensures the accuracy of the regulation. This design realizes the precise regulation of the drying airflow, solves the problem in the existing technology that it is impossible to adjust the airflow according to the characteristics of different feed additives, and improves the drying quality and energy utilization efficiency.

[0019] 3. The limiting device achieves precise control of the adjusting sleeve position through the ingenious cooperation of the large gear, rotating rod, rotating sleeve, internal gear ring, main gear, and driven gear. The design of the locking block, locking groove, push spring, and tension spring ensures the reliability and flexibility of the limiting. The setting of the limiting sleeve prevents the push spring from being over-compressed, extending the service life of the device. This multi-limiting mechanism not only improves the adjustment accuracy but also enhances the stability and reliability of the entire device, enabling operators to precisely control the drying process according to actual needs, meeting the requirements of modern production for refined control.

The multiple sets of locking blocks 30 are pulled outward by the tension spring 34 to disengage them from the locking slot 31, thereby... Release the limiting position of the rotating sleeve 26, and then rotate the rotating sleeve 26 to drive the internal gear ring 27 to rotate. The internal gear ring 27 meshes with multiple sets of main gears 28 to drive the rotating rod 25 to rotate. The rotating rod 25 drives the driven gear 29 to mesh with the large gear 24.
