Description

TECHNICAL FIELD

[0001] The utility model belongs to dryer technical field, concretely relates to a kind of efficient dryer for organic fertilizer and biofertilizer. BACKGROUND

[0002] Organic fertilizer and biofertilizer are frequently used fertilizer types in agricultural production process, wherein organic fertilizer refers to the fertilizer prepared after fermentation and decomposition of organic materials such as animal and plant residues and excrement, which is rich in organic matter and various nutrient elements, and can improve soil structure, increase soil fertility and promote plant growth. The types of organic fertilizer include compost, green manure, manure and cake fertilizer, etc. Biofertilizer refers to the fertilizer containing specific microorganisms, which can directly or indirectly promote plant growth. Biofertilizer can improve the utilization rate of nutrient elements in soil, enhance the disease resistance of plants and improve the soil environment through the activity of microorganisms. Common biofertilizers include rhizobium fertilizer, nitrogen-fixing bacteria fertilizer and phosphorus bacteria fertilizer.

[0003] For organic fertilizer and biofertilizer, the moisture content of granules after granulation is high, and the moisture needs to be reduced to a certain standard through drying to avoid powdering and caking during later storage, thereby ensuring the quality and effect of the fertilizer. Moreover, the volume of organic fertilizer and biofertilizer after drying is reduced, and the moisture is reduced, which also makes the material easy to transport and store.

[0004] There are drum dryers for fertilizer drying in the prior art, such as CN212362691U discloses a drum dryer for uniform drying of organic fertilizer, which comprises a suspended drum, an oven is installed at the rear end of the drum, a dispersion frame is fixed inside the drum, a steel wire mesh is connected to the inner side of the dispersion frame, the width of the dispersion frame is smaller than the inner diameter of the drum, a plurality of dispersion rods are welded at equal intervals on the long side surface of the dispersion frame, blade bevels are arranged at the upper and lower ends of the dispersion rods, and arc-shaped spades are welded at the outer ends of the dispersion rods. The organic fertilizer in the patent falls on the dispersion frame while rotating in the drum, and is scattered by the steel wire mesh. Due to the time period of blocking the organic fertilizer by the steel wire mesh, the drum with the organic fertilizer at the bottom will move upwards, so that the organic fertilizer falling from the steel wire mesh is not mixed with the previous one, and the organic fertilizer is uniformly dispersed and heated, which can be quickly dried.

[0005] The drum dryer disclosed in the patent has the following disadvantages: the end of the drum away from the oven is open, the fertilizer to be dried stays in the drum for a short time, which is not conducive to the drying operation of the fertilizer; secondly, the drying process mainly relies on the hot air blown into the drum by the air blower, which carries away the moisture in the fertilizer to be dried in the drum, the drying mode is single, and the drying efficiency is limited, which needs to be further improved.
