Counterpoised squeezing granulator

Abstract

The invention relates to fertilizer production equipment, and specifically relates to a counterpoised squeezing granulator. The squeezing granulator comprises a shell, a sieve plate arranged in the inner cavity of the shell, a rotation shaft arranged in the center of the sieve plate, a roller rack connected to the rotation shaft, and a roller arranged on the roller rack through a bearing. The sieve plate in a conical structure is arranged in the shell. Sieve pores are arranged in the sieve plate. A finished product chamber is arranged on the lower surface of the sieve plate. The rotation shaft is connected to a driving motor through transmission connection. The external end of the roller rack is provided with a pulley, which is arranged on the lower end of a compression ring so as to balance the force on two ends of the roller rack. A gap is arranged between the sieve plate and the internal wall of the shell. The squeezing granulator has the advantages of compact structure, high efficiency, enclosed operation and little pollution, moreover, the force on the roller rack is balanced, and thus the service life is prolonged.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to a counterweight 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 burning cost, and can ...

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
