Flow-type circulatory burdening squeezing granulator

Abstract

The invention relates to fertilizer production equipment, specifically to a flow-type circulatory burdening squeezing granulator. The flow-type circulatory burdening squeezing granulator comprises a housing, a sieve plate fixedly installed inside a cavity of the housing, a rotating shaft mounted at the center of the sieve plate, a roller rack connected on the rotating shaft and a roller installed on the roller rack through a bearing. The sieve plate with a conical structure is arranged inside the housing. The sieve plate is provided with sieve pores. A finished product warehouse is arranged below the sieve plate. The rotating shaft is in transmission connection with a drive motor. An outer end of the roller rack is provided with a pulley, which is installed at the lower end of a compression ring to balance force on applied two ends of the roller rack. There is a gap between inner walls of the sieve plate and the housing. The squeezing granulator has advantages of compact structure, closed operation, high efficiency and less pollution. The stress is evenly applied on the roller rack, thus prolonging service life.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to a flow-type circulation batching extrusion granulator. Background technique [0002] The traditional granular fertilizer production generally adopts the slurry method or humidified granulation method, which requires the introduction of water to granulate, and consumes a lot of energy to dry the water in the production process, which produces a lot of waste gas, waste water, waste, polluting the environment. In this production process, the materials are dried with the preheated air of the hot blast stove, and the burning of coal in the hot blast stove produces a certain amount of SO 2 gas, polluting the atmosphere. Extrusion granulation does not need to burn coal in the whole production process, which not only saves energy, but also does not produce SO 2 gas. No steam is needed in the granulation process, which can save boiler construction investment and coal burni...

AI Technical Summary

Problems solved by technology

However, the roller is fixedly connected to the rotating shaft by means of one-sided connection at the inner end, and the outer end of the roller is suspended in the air. During operation, the axle of the roller is subject to a large moment, which is prone to bending or even breaking of the axle, and repairs after failure The replacement work is very troublesome, which affects the service life and efficiency of the whole machine

In addition, since the auger is fixedly connected to the drive shaft, the auger always works during the extrusion and granulation process, and excessive material accumulates in the roller bin, which not only increases the load on the roller, but also easily causes material blockage, causing the whole machine to be stuck. death, or even the risk of burning the drive motor
