Harmless continuous treatment device for dead livestock and poultry

Abstract

The invention relates to a harmless continuous treatment device for dead livestock and poultry, and belongs to the technical field of sterilization and disinfection of the dead livestock and poultry. The treatment device comprises a sealing cover, a feeding cavity, a crushing and stirring screw, fixed knives, a machine barrel, microwave generators, an exhaust port and a discharging cavity; in the operation process of the treatment device, after carcasses of the dead livestock and poultry enter the feeding cavity, the sealing cover is closed, and the carcasses of the dead livestock and poultry in the feeding cavity are cut by crushing knives under the action of gravity, the materials falling into a crushing cavity are continuously crushed, the materials are pushed backwards in the crushing process, the materials meeting the microwave sterilization particle size are conveyed into a sterilization cavity through conveying blades, and pathogenic microorganisms in the materials in the sterilization cavity are completely killed under the combined action of the heat effect and the non-thermal effect of the high-power microwaves; the moisture content of the sterilized materials is reduced, and the solid materials are extruded after being compressed in the discharging cavity at the tail end of the machine barrel so that further resource reuse can be realized; and after sterilization, the separated water vapor and waste gas are discharged from the exhaust port.

Description

technical field [0001] The invention relates to a harmless continuous treatment device for sick and dead livestock and poultry, belonging to the technical field of sterilization and disinfection of sick and dead livestock and poultry. Background technique [0002] According to statistics, in 2012, the number of cattle, pigs and poultry in my country was 106.2676 million, 666.8643 million and 13.73 billion respectively. The mortality rate of livestock and poultry in farms is generally between 5% and 10%. If calculated according to the mortality rate of 5%, the total number of dead livestock and poultry in my country in 2012 was about 730 million (only). will rise. It can be seen from the above data that the number of dead livestock and poultry in my country is very large every year. The dead livestock and poultry themselves carry many pathogenic microorganisms. If they are not handled properly, they will pollute environmental resources such as soil and water. Affect the contr...

Problems solved by technology

Although the incineration method and the chemical method can guarantee the killing effect on pathogenic microorganisms, they cannot realize the recycling of waste, and incineration will cause great pollution to the environment; the processing time of high-temperature cooking and biodegradation is long, Moreover, the treatment efficiency of the high-temperature cooking method is relatively low, which cannot meet the requirements of high-efficiency continuous treatment.
