Description

Technical Field

[0001] This utility model relates to the field of mixed fertilizer production technology, specifically a filtration mechanism for controlled-release blended fertilizer production. Background Technology

[0002] Blended fertilizers, also known as BB fertilizers or dry-mixed fertilizers, are chemical fertilizer products containing at least two or all of the three major nutrients: nitrogen, phosphorus, and potassium. They are prepared using single-element or compound fertilizers as a base material through a simple physical mixing process, in which no significant chemical reactions occur. Because the production process of blended fertilizers is relatively straightforward, when blending and fertilization can be closely integrated and completed within the same day, the product's storage stability is not a primary concern. However, in many countries, blended fertilizers need to undergo packaging and storage for a period of time; therefore, the product's storage performance becomes particularly important.

[0003] To ensure the quality of blended fertilizers, all raw materials must be kept dry, possessing uniform particle shape and high strength to prevent problems such as water absorption, clumping, or particle stratification during storage and transportation. In the production process, blended fertilizers also require drying and filtration to prevent clumping. However, in current production practice, drying and filtration are often carried out on different equipment, which undoubtedly increases the complexity and cumbersomeness of the operation. Therefore, this case study was developed to address these issues in depth. Utility Model Content

The trumpet-shaped diversion block is installed inside both the well-shaped diversion block and the filter screening box. A pair of horizontal telescopic grooves are provided on the filter screening box. A pair of bidirectional threaded rods are respectively inserted into the inner side of the pair of horizontal telescopic grooves via bearings. Two pairs of horizontal threaded pipes are respectively inserted into two pairs of horizontal telescopic bearing blocks, and the two pairs of horizontal threaded pipes are respectively fitted onto a pair of bidirectional threaded rods. Two pairs of horizontal telescopic limiting shafts are respectively inserted into the inner side of the pair of horizontal telescopic grooves, and the two pairs of horizontal telescopic limiting shafts are respectively...

[0006] It should be noted that, in the above process, after the fertilizer is mixed and stirred by the mixing tank, it falls into the inner side of the filter screening box. The horizontal drive motor drives the horizontal gear set on the drive end of the horizontal drive motor, which in turn drives a pair of double-threaded rods. The pair of double-threaded rods drive two pairs of horizontal threaded tubes on them. The relative extension and retraction of the two pairs of horizontal threaded tubes drives two pairs of horizontal telescopic bearing blocks on them. The two pairs of horizontal telescopic bearing blocks drive a pair of extrusion rollers on them to extend and retract relative to each other. The extrusion rollers extrude fertilizer and compress it along the well-shaped guide block. The fertilizer then falls onto the inclined filter screen on the inclined screening concave block. Several buffer shafts and several buffer spring sets buffer the inner side of the inclined screening concave block. At the same time, the inclined screening concave block and the inclined current mesh on it are used for screening and filtration by the lifting and vibrating of the inclined screening concave block.

[0009] It should be noted that, as described above, the flow stretching drive on the U-shaped flow pipe drives the flow stretching shaft on it, which in turn drives the flow stretching blades on it to rotate, thereby drawing the powder back to the inside of the mixing tank.

[0010] Preferably, the filter screening box is equipped with a buffer plate and a buffer shaft.
