Embodiment 1

[0023] Such as figure 1 As shown, the compound fertilizer granule screening, loading and drying system includes a feeding mechanism and a drying device. The feeding device includes a preparation track 1 and a weighing track 2 connected to it. The top of the weighing track 2 is provided with a discharge device. The device includes a silo 3, a discharge plate 4, and a gate 3.1. The silo 3 is provided with a screen 3.2. The gate 3.1 is connected to the load cell 6 on the weighing track 2, and the rear of the weighing track 2 is connected to convey Track 5, the conveying track 5 can transport the material to the drying device. The stripper plate 4 comprises the upper section 4.1 of the stripper plate and the lower section 4.2 of the stripper plate, the upper section 4.1 of the stripper plate has small holes, and the lower part of the upper section 4.1 of the stripper plate is provided with a fine material conveying mechanism 7.

[0024] The drying device includes a drying room 8....

Embodiment 2

[0029] In this embodiment, the difference from Embodiment 1 is that the weighing track 2 is also provided with a weight safety limiting device, which can stop the operation of the preparation track 1, the weighing track 2 and the delivery track 5 in time, and when When the gate 3.1 accidentally dumps materials, the weighing track 2 will not run, thereby preventing accidents from happening.

[0030] In addition, in this embodiment, another drying method is provided, that is, when the 4 charging boxes A are respectively filled with compound fertilizer granules, when they enter the corresponding 4 compartments, they are baked at the same time. Temperature detector 12 and humidity detector 13 monitor temperature and humidity. Thereby, the purpose of simultaneous baking of multiple materials can be achieved.

[0031] The rest of the working principles are the same as in Embodiment 1.

Abstract

The invention discloses a screening, loading and drying system for compound fertilizer granules. The screening, loading and drying system comprises a feeding mechanism and a drying device and is characterized in that a feeding device comprises a prepared rail and a weighing rail which is connected with the prepared rail; a discharging device is arranged at the top of the weighing rail and comprises a material bin, a discharging plate and a gate which is connected with a weighing sensor on the weighing rail; a transfer rail is connected to the rear of the weighing rail and can transfer the materials into the drying device; operation of parts of the feeding device is controlled through a PLC (programmable logic controller) system. The screening, loading and drying system is ingenious and reasonable in design and high in systematicness; with the compound fertilizer granule loading and drying functions, the system is high in automation level and can be used in combination of existing granule making equipment; in addition, by the arrangement of the material bin with a screen, acceptability of the compound fertilizer granules can be improved.

Description

technical field [0001] The invention relates to compound fertilizer drying equipment, in particular to a compound fertilizer granule screening, loading and drying system. Background technique [0002] At present, the existing main equipment for the production of compound fertilizers includes disc granulation equipment and roller compaction granulation equipment, etc., and the latest compound fertilizer production equipment also includes liquid spray granulation equipment, which passes through the granulator Add steam and water to the raw materials, add acid and ammonia to neutralize and carry out acid granulation, and make a compound fertilizer with qualified nutrients and qualified appearance. However, after granulation, it is still necessary to dry the compound fertilizer to adjust its moderate humidity, so as to be able to adapt to the use of more markets, which requires a system that can automatically load and dry to solve these problems Contents of the invention [0...
