Technology and apparatus for producing wall sticking prevention multifunctional fertilizer

Abstract

A technology for producing a wall sticking prevention multifunctional fertilizer relates to the technical field of sedimentation furnace production of lime nitrogen multifunctional fertilizers. The technology comprises the following steps: reaction materials are crushed and mixed; foundry returns are crushed; the reaction materials and the foundry returns are respectively fed into a material scatter, the scatter makes reaction material dusts charged and the inner wall of a reaction segment likely charged, and classic repulsion makes the reaction material dusts not adhered to the wall of a furnace; a thermometer is used to monitor the temperature of the furnace and control the added foundry returns lime nitrogen, and the temperature of the furnace is controlled to be in a proper range; anda double-roller discharging system upwards crushes and discharges during tapping, and continuous vibration makes the furnace material fast and stably settled. The invention also provides an apparatusinvolved by the technology. The apparatus comprises a reaction material chamber, a foundry return chamber, a spiral feeder, the electrostatic generation type scatter, a settling furnace, the double-roller discharging system, the thermometer and an automatic control system. The technology and the apparatus effectively avoid the dusts from being adsorbed to the wall of the furnace, and avoid meltingwall sticking and hardening wall sticking caused by too high or too low temperature.

Description

Technical field: [0001] The invention relates to the technical field of lime-nitrogen multifunctional fertilizer production by a settling furnace method, in particular to a multifunctional fertilizer production process with an anti-sticking wall and equipment thereof. Background technique: [0002] The scientific name of lime nitrogen is calcium cyanamide, which is a chemical fertilizer that has been used for more than 100 years. From the 1960s to the mid-1970s, lime nitrogen began to be widely used in my country's agriculture, such as as a base fertilizer for rice, adjusting soil acidity, and supplementing plant calcium. [0003] At present, domestic lime nitrogen production mainly includes fixed furnace method, settling furnace method and rotary furnace method. Due to the low investment, low energy consumption and the advantages of producing high-quality lime nitrogen, the settling furnace method is adopted by most domestic enterprises. At present, the high-quality lime n...

Problems solved by technology

[0013] In view of this, it is necessary to design a multi-functional fertilizer production process and equipment with anti-sticking walls, and at the same time solve the problems of softening, deformation and easy wear of the spreader, inconvenient operation of the charge after the reaction, and unstable sinking of the charge.
