Sterilizing equipment before manufacturing fertilizers from waste

Abstract

The invention discloses sterilizing equipment before manufacturing fertilizers from waste. The sterilizing equipment comprises a mounting bottom plate extending leftwards and rightwards, wherein a sterilizing body is fixedly arranged at the upper end of the mounting bottom plate through a left mounting bracket, a sterilizing space is formed in the sterilizing body, an oil storage space is formed in the sterilizing body, high-temperature steam is used for sterilizing raw materials for manufacturing the fertilizers of waste, and besides, according to the characteristic of oil bath heating, wateris heated to generate steam, so that the temperature stability in a heating process can be guaranteed, the heating is uniform, and the operation controllability is improved. Besides, the water beforebeing heated is used for condensing the steam, and residual temperature of the steam in the condensing process is used for performing primary heating on the water which flows through the steam, and energy can be subjected to multistage utilization, so that the using efficiency can be improved, and besides, according to cooperation of the pressure of the steam and the elasticity of springs, whether circulation of the sterilizing space and outside exists or not is controlled, the possibility of destroying caused by too high internal pressure of equipment can be avoided, and later stage maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sterilization, in particular to a sterilization equipment before the manufacture of waste fertilizers. Background technique [0002] Waste fertilizer refers to domestic garbage, sewage, waste residue, slaughterhouse waste, etc. that can be used as fertilizer. It is another way to deal with this garbage. It needs to be sterilized before manufacturing to eliminate some harmful bacteria. Most of the existing treatment methods use heat treatment. However, it is difficult for the existing equipment to stably control the temperature during the heat treatment process, resulting in uneven heating and affecting the final sterilization effect. At the same time, this heat treatment method consumes a lot of Energy, the utilization rate of energy is low, which leads to high cost of sterilization. At the same time, the equipment is in a state of high temperature and high pressure for a long time during the processing p...
