Abstract
Description
Technical Field
[0001] The present invention relates to a harmless treatment process and device technology for dead animals, specifically to a harmless treatment process and device for dead animals, belonging to the technical field of harmless treatment of dead animals. Background Art
[0002] In recent years, when major animal epidemics occur, it has brought great harm to the health of breeding industry personnel. Animal health and safety issues not only affect the growth and health of animals and economic benefits, but also pose a threat to human health and social stability. Animal health and safety issues have become the focus of common concern in the whole society. There are many factors causing this situation, and one of the important reasons is that dead animals cannot be effectively and timely harmlessly treated. Dead animals are not harmlessly treated in accordance with relevant national regulations, which is extremely likely to cause the spread of major animal epidemics and zoonoses. Especially when dead animals flow into the consumer market, it will directly threaten the physical health of the people. Strengthening the harmless treatment of dead animals is related to the healthy development of the animal husbandry and the health and safety of the people. In some places, farmers in breeding farms throw dead animals randomly, seriously affecting public health and safety. At present, the main harmless treatment methods for dead animals include incineration method, rendering method, burial method, fermentation method, etc. The incineration method is thorough but consumes a large amount of energy and has low economic benefits; the burial method occupies a large amount of land resources and is easy to pollute groundwater; the fermentation method takes a relatively long time and cannot be used for the treatment of a large number of dead animals. The current rendering method uses high temperature and high pressure, with a large processing capacity and the treatment products are more conducive to being used as organic fertilizers, but there are still deficiencies: 1. Dead animals are directly fed without being broken, which requires relatively high equipment requirements and a long treatment time; 2. Secondary pollution is easily caused during the treatment process; 3. Atmospheric drying is adopted, with large energy consumption, a large amount of waste gas and waste water generated, and a large treatment cost. Therefore, the harmless treatment device and process method for dead animals need to be further improved and optimized. Therefore, it is very necessary to invent a harmless treatment process and device for dead animals.

Embodiment
[0018] The present invention will be further described below in conjunction with the embodiments. Specific embodiment
[0019] See Figure 1It can be known that a harmless treatment process and device for dead animals according to the present invention is composed of a sealed workbench 1, a robotic manipulator 2, a flipping mechanism 3, a driving mechanism 4, a sealed chamber 5, a conveying mechanism 6, a liquid nitrogen inlet 7, a main machine 8, a temperature measuring tube 9, a GMP heat preservation area 10, an induced draft fan 11, a pipeline 12, an external cyclone collector 13, a driving power supply 14, a microwave control tube 15, a stirring shaft 16, a discharging cylinder 17, a feeding gate 18, a microwave vacuum dryer 19, a liquid nitrogen cryogenic pulverizer 20, an automatic connection device 21, and a robotic water curtain separator 22; and it is characterized in that: the robotic manipulator 2 and the flipping mechanism 3 are installed on the sealed workbench 1; the driving mechanism 4 is installed on the left side of the sealed chamber 5; the conveying mechanism 6 is installed under the sealed chamber 5; the liquid nitrogen inlet 7 is installed on the left side of the main machine 8; the temperature measuring tube 9 is installed inside the main machine 8; the main machine 8, the temperature measuring tube 9, and the induced draft fan 11 are installed inside the GMP heat preservation area 10; there are two pipelines 12, the left ends of which are respectively connected to the main machine 8 and the induced draft fan 11, and the right ends are connected to the external cyclone collector 13; the driving power supply 14 is above the microwave control tube 15, above the stirring shaft 16, and above the discharging cylinder 17; the feeding gate 18 is installed under the external cyclone collector 13 to control the feeding speed; the vacuum dryer 19 is a device that removes moisture inside the packaging container by evacuating the air inside the packaging container to a predetermined vacuum degree. During drying, the tank body is in a vacuum state, and the jacket is heated by hot water (or steam and heat transfer oil). As the tank body rotates slowly, the material moves in a "diamond trajectory" up and down, inside and outside the tank body, absorbs and evaporates, and water vapor is continuously discharged through the vacuum pipeline to achieve the purpose of drying the material; the liquid nitrogen cryogenic pulverizer 20 can perfectly achieve the pulverization treatment of the material, and the process of pulverizing the material to be processed with liquid nitrogen as the medium is relatively safe and reliable. Some special materials that are not easy to pulverize become very easy to pulverize after adding liquid nitrogen; the automatic connection device 21 connects the winding device, industrial robot, control cabinet, and relays and capacitors of the entire device to achieve control; the robotic water curtain separator 22 is an automatic sprinkler fire extinguishing system mainly composed of a water curtain nozzle, a deluge alarm valve group or a heat-sensitive deluge valve, a water supply and distribution pipeline, a control valve, and a water flow alarm device, which mainly plays the roles of fire resistance, cooling, and isolation.
[0020] See Figure 1It can be seen that for a harmless treatment process and device for dead animals according to the present invention, first, low-temperature storage is carried out. The body is first placed in an environment of -18°C for precooling and preservation. Secondly, the frozen animal body is pre-crushed using a robotic water jet. The device identifies the body shape through a vision system and automatically programs, and then uses a high-pressure water jet to impact the body for small-piece treatment through water jet cutting. Thirdly, the small pieces of the cut body are automatically transported to a liquid nitrogen cryogenic pulverizer through a fully sealed device. Fourthly, the small pieces of the body then enter the feed pipe of the liquid nitrogen cryogenic pulverizer and are rapidly cooled using liquid nitrogen at -196°C in the pipe, making the small pieces of the body quickly cool down and become brittle. The embrittled small pieces of the body enter the pulverizing chamber and finally form a powdery flour through physical means such as impact and friction. Fifthly, the powder enters a microwave vacuum dehydration dryer through a pipe for sterilization and drying. Microwaves have a sterilization effect, and most of the moisture can be removed by vacuum drying at a temperature of 60 - 70°C. f. The processed powder is placed in a container and sampled for bacterial detection. The pressure in the container in step f is 0.5 MPa - 0.8 MPa, the temperature ≥ 80°C, and the time for maintaining the temperature and pressure in the container in step f is ≥ 40 min.
[0021] See Figure 1It can be seen that the present invention provides a harmless treatment process and device for dead animals, in which the collected animal carcasses are directly dumped into a raw material bin by a dump truck. If the collected materials are too much to be processed in time, they are temporarily stored in a cold storage. The live animals are killed by electric shock, and the animal carcasses are stored at low temperature. The bodies are first placed in a -18°C environment for pre-cooling and preservation; when the feeding and crushing treatment work begins, the screw conveyor at the bottom of the raw material bin pushes the animal carcasses to the crusher. The frozen animal bodies are pre-processed by crushing with a robot water jet, and the equipment recognizes the body shape through a visual system and automatically programs it, and then uses a high-pressure water jet to impact the body, and cuts it into small pieces through water jet cutting; the cut body small pieces (the material is crushed into pieces less than 50 mm) are automatically transported to a sealed workbench 1 through a fully sealed device, and are sent to a sealed bin 5 through a robot manipulator 2 and a flipping mechanism 3, and are transported to a feed pump through a driving mechanism 4 and a conveying mechanism 6 through a screw conveyor. The feed pump transports the material to a cooking dryer through a sealed pipeline, and then The main machine 8 feeds the material into the liquid nitrogen cryogenic pulverizer 20; liquid nitrogen is provided through the liquid nitrogen inlet 7, and the system temperature is controlled at any time through the temperature measuring tube 9 and the GMP insulation area 10. Then the small pieces of the body enter the liquid nitrogen cryogenic pulverizer through the feeding pipeline 12 and the external cyclone collector 13, the driving power supply 14, the microwave control tube 15, the stirring shaft 16, the unloading cylinder 17, etc. The feeding gate 18 is used to control the feeding speed; liquid nitrogen cryogenic pulverizer 20, the automatic connection equipment 21, the robot The water curtain is separated 22 and liquid nitrogen at -196℃ is used in the pipeline for rapid cooling, so that the small pieces of the body are quickly cooled and become brittle. The brittle small pieces of the body enter the crushing chamber and are formed into flour-like powder through physical methods such as impact and friction. The powder enters the microwave vacuum dehydration dryer 19 through the pipeline for sterilization and drying. Microwaves have a sterilization effect. The temperature is 0.5MPa-0.8MPa, ≥80℃, and kept warm for 40 minutes. The treated powder is placed in a container and sampled for bacteria detection.
