Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of organic fertilizer production drying technology, especially relates to a hot blast furnace of organic fertilizer drying. BACKGROUND

[0002] In the process of modern agricultural sustainable development, organic fertilizer becomes an important input in agricultural production by virtue of its advantages of improving soil and improving crop quality, and organic fertilizer production covers multiple links such as raw material collection, fermentation and drying. Drying is a key step to ensure product quality and storage performance. The raw materials of organic fertilizer are rich and diverse, including livestock manure, crop straw and kitchen garbage. The initial moisture content of these raw materials is high, which not only greatly increases the transportation cost, but also easily causes odor and mold during storage due to microbial growth, thereby affecting the fertilizer efficiency and even causing negative effects on soil and crops. Therefore, removing excess moisture from organic fertilizer through drying is crucial for improving product quality, extending storage period and enhancing use safety.

[0003] To solve the technical problems in the drying process of organic fertilizer, many researches and innovations have been carried out in the industry. For example, a kind of organic fertilizer dryer is disclosed in Chinese patent with publication number "CN220153150U". The device realizes vibration screening through the cooperation of elliptical blocks and return springs, and uses stirring blades to turn and dry the organic fertilizer, which to some extent solves the problems of uneven drying degree and difficulty in removing foreign matter in traditional dryers.

[0004] However, such existing drying devices still have obvious defects in actual application. Firstly, the layout of stirring blades in the heating bin forms multiple relatively independent channels, which seriously hinders the circulation of hot air. In addition, the stirring method cannot achieve uniform tumbling of the material, resulting in insufficient contact between the material and hot air and low drying efficiency. Secondly, the bottom discharge structure of the equipment relies on manual operation to open. Considering that organic fertilizer often contains components such as manure and kitchen garbage, manual operation can easily cause workers to directly contact pollutants, which poses a great health and safety risk and does not meet the needs of modern and automated production. These technical bottlenecks limit the improvement of efficiency and quality of organic fertilizer drying production, and there is an urgent need to optimize and improve the existing drying equipment to meet the higher requirements of modern agriculture for organic fertilizer production.

[0010] As a preferred technical scheme, the closed mechanism comprises side plates fixedly connected to the top and bottom of the one side of the furnace body, respectively, an electric push rod is fixedly connected to the outer side of the side plate, a sealing plate is fixedly connected to the output end of the electric push rod and penetrates through the side plate, and the sealing plate covers the outside of the feed slot and the discharge slot, respectively.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] First, the stirring mechanism of this device, through precision transmission, can achieve coordinated stirring and hot air circulation. During operation, the drive motor drives the rotating shaft, stirring frame, spiral stirring blades and stirring rod to rotate, which not only fully stirs the material, but also promotes air circulation in the furnace. After the hot air blower is started, the hot air is conveyed through the conveying pipe and quickly and evenly contacts the material in the airflow channel formed by stirring, improving the drying effect. The spiral stirring blades are attached to the furnace wall, and the drive motor rotates alternately in the forward and reverse directions to realize bidirectional material conveying and tumbling. Combined with the precise delivery of hot air to the bottom and sides of the furnace, the drying efficiency is greatly improved and the material is dried evenly.

[0016] Secondly, this device adopts a closed mechanism, which can effectively improve the convenience and hygiene of the equipment. During use, it consists of an electric push rod and a sealing plate. When materials are added or discharged, the electric push rod drives the sealing plate to slide open the discharge chute and the feed chute. After the operation is completed, the seal is reset. This design avoids manual contact with materials and eliminates hygiene hazards. When discharging, the spiral stirring blades with reverse threads drive the motor to rotate in the opposite direction, pushing the material towards the middle of the furnace body. In conjunction with the central discharge chute, the material is discharged quickly and smoothly, improving the discharge efficiency and making the equipment operation more intelligent and user-friendly.
