Energy-saving and automatic sterilization system in dead animal treatment process

Abstract

The invention discloses an energy-saving and automatic sterilization system in dead animal treatment process. The energy-saving and automatic sterilization system comprises a crusher, a high-temperature refining tank and an oil residue separation tank which are sequentially arranged, a conveying tank is arranged between the crusher and the high-temperature refining tank, the high-temperature refining tank is connected with a boiler through a heat conduction circulating pipe for heat transfer, and an outlet is connected with the oil residue separation tank; an oil outlet of the oil residue separation tank is connected with an underground oil pool, the underground oil pool is connected to the crusher through a cleaning pipe, a cleaning oil pump is arranged on the cleaning pipe, and the heatconduction circulating pipe passes through the conveying tank. High-temperature oil temporarily stored in the underground oil pool is conveyed into the crusher to be sprayed and disinfected, the residual amount of germs is reduced, the risk of environmental damage is reduced, meanwhile, the heat conduction circulating pipe between the boiler and the oil residue separation tank preheats the conveying tank, frozen broken animal carcasses in the conveying tank can be prevented from being bonded again, the conveying tank is prevented from being blocked, an existing system is fully utilized, othersterilization and heating devices do not need to be arranged, and the device installation cost and energy consumption are reduced.

Description

technical field [0001] The invention relates to the field of harmless treatment of dead animals, in particular to an energy-saving and automatic sterilization system during the treatment of dead animals. Background technique [0002] At present, the harmless treatment methods for dead animal corpses include high-temperature method, in which the fat in dead animal corpses is refined through high temperature. When the high temperature method is used, the animal carcass is usually crushed by a crusher first, and then transported to a high temperature refining tank, and the oil is extracted under the action of high temperature. Among them, the temperature of the high-temperature refining tank is mainly provided by boilers, etc. The boiler heats the heat transfer medium and transports it to the high-temperature refining tank and other equipment to form heat transfer, and then the heat transfer medium returns to the boiler to continue heating to form a circulation loop. The refin...

Problems solved by technology

[0003] The following problems were found during the actual processing by the above method: first, the amount of germs contained in the animal carcasses out of the cold storage is still very high, and it still needs to be further disinfected before entering the high-temperature refining tank to reduce the damage to the environment. It is not convenient to install equipment for disinfection such as machines; secondly, the animal carcasses from the cold storage are still in a frozen state after being crushed in the crusher.
