Rotary drum type chemical fertilizer dryer

Abstract

The invention discloses a rotary drum type chemical fertilizer dryer which comprises a drum body, a spiral baffle, a motor, fans, filter nets, a discharge port, a water outlet and a condenser, wherein the whole drum body is connected with the motor; the spiral baffle is arranged in the drum body; multiple fans are arranged around the drum body; the discharge port is formed at the lower part of the rear end of the drum body; the drum body consists of multiple layers of steel filter nets; multiple layers of filter nets are arranged at the rear end of the drum body; the condenser is arranged at the tail end of the drum body; and the lower end of the condenser is connected with the water outlet. On the whole, the rotary drum type chemical fertilizer dryer disclosed by the invention is simple in structure and simple and convenient to produce and mount; and through the rotation of the drum and the effect of drying air around the drum, the chemical fertilizer can be dried uniformly, the production cost of the chemical fertilizer is reduced, and the quality of the chemical fertilizer is improved.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer drying devices, and relates to a chemical fertilizer drying device, in particular to a rotary drum type chemical fertilizer drying device. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility level. It is one of the material foundations of agricultural production. Fertilizer is easy to absorb moisture, so the granular fertilizer is dried by dryer to increase the strength of fertilizer particles. At present, in fertilizer production enterprises, steam is generally used to dry in a drum furnace, and then the fertilizer is dried by the continuous rotation of the drum furnace. However, in the production process of fertilizer, the production volume of fertilizer is large, so the drying in the drying furnace is uneven, which affects the quality of fertilizer, and a large amount of...

Problems solved by technology

[0002] Fertilizer is a kind of substance that provides one or more essential nutrient elements for plants, improves soil properties, and improves soil fertility. It is one of the material bases of agricultural production. In the process of fertilizer production, drying is a key step. Because Fertilizer is easy to absorb moisture, so the granular fertilizer is dried through a dryer to increase the strength of fertilizer particles. At present, in fertilizer production enterprises, steam is generally used to dry in a drum furnace, and then the fertilizer is dried by the continuous rotation of the drum furnace. However, in the process of fertilizer production, the production of fertilizer is relatively large, so the drying in the drying furnace is uneven, which affects the quality of the fertilizer, and a large amount of insufficiently dried fertilizer will cause damage to the drum furnace itself, which will increase the cost of fertilizer production
