Description

Technical Field

[0001] The invention belongs to the technical field of resources and environmental protection, and in particular relates to a device for harmlessly processing dead poultry and livestock carcasses. Background Art

[0002] The livestock industry, or livestock farming, refers to the economic activities of humans raising domesticated animals, such as chickens, ducks, geese, pigs, cattle, sheep, etc., to obtain animal products such as meat, eggs, milk, fur, etc. This industry is an important part of agriculture. People provide feed, water, space and environment according to the needs of animals to ensure the growth, reproduction and healthy development of animals. The livestock industry not only provides people with abundant food resources, but also has certain cyclical and seasonal characteristics. The price of its products fluctuates due to the influence of supply and demand.

[0003] In the process of livestock breeding, when livestock are in a state of nutritional imbalance, lack of exercise or bad environment, their physical fitness will decline, their resistance will be poor, and they will be susceptible to diseases, including but not limited to fowl cholera, egg-laying fatigue, influenza, etc. These diseases are caused by pathogens, are contagious and have a high mortality rate. Once infected, livestock may die quickly;

[0004] Dead poultry and livestock may carry pathogens. If not handled in time, they can easily become the source of infectious diseases and threaten human and animal health. The carcasses of dead poultry and livestock will produce odors and harmful gases, affecting the surrounding environment and residents' lives. Harmless treatment can reduce pollution. Furthermore, handling poultry and livestock can prevent illegal processing and sales of dead poultry and livestock, which seriously affect food safety. Therefore, harmless treatment of dead poultry and livestock is an important measure to prevent the spread of diseases, protect the environment, ensure food safety and promote resource recycling. It is of great significance to maintain public health safety and ecological civilization.

[0005] One of the most common and mature treatment methods currently is cremation, which is to directly carbonize the carcasses of livestock and poultry through high temperatures, which can effectively kill pathogens and prevent the spread of diseases. However, in order to ensure that the carcasses of dead livestock and diseased animals are completely burned and carbonized, a relatively high temperature must be reached. According to the "Technical Specifications for the Harmless Treatment of Dead and Diseased Animals" and actual operating experience, the temperature of the combustion chamber should reach above 850°C, so it is often necessary to install various auxiliary instruments on the incinerator, which will consume a lot of resources for one use, including but not limited to electricity and gas. However, when sick livestock and poultry do not die in large numbers due to rapid processing, the use of cremation is not economical enough, so better equipment is needed to meet the usage needs. Summary of the invention

[0006] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a device for harmlessly treating the carcasses of dead poultry and livestock.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0014] The conversion mechanism includes an inclined baffle plate arranged in the inclined slot and a straight baffle plate arranged beside the through slot. A horizontal plate is connected between the anaerobic fermentation box and the waste gas treatment box. A first telescopic cylinder is installed on the horizontal plate. The output end of the first telescopic cylinder is connected to the inclined baffle plate. A second telescopic cylinder is installed on the top of the anaerobic fermentation box. The output end of the second telescopic cylinder is connected to a displacement plate. The displacement plate is connected to the straight baffle plate.

[0015] It is further defined that the incinerator is equipped with a flame monitoring element, a temperature monitoring element and a gas pressure monitoring element. Such a design ensures the normal and controlled operation of the incinerator.

[0016] It is further defined that the incinerator, the anaerobic fermentation box and the waste gas treatment box are all equipped with a feeding cylinder, and the feeding cylinder is equipped with a sealing cover plate. Such a design is conducive to the addition of fuel sources, auxiliary materials and additives, and is also conducive to the rapid input of poultry and livestock carcasses.

[0017] It is further defined that a mounting support is installed on the outer side of the incinerator, and the motor is installed on the mounting support. Such a design supports the motor and ensures normal use of the motor.

[0018] It is further defined that the first component box is equipped with a thermometer, a pressure gauge, a liquid level gauge, a pH detector, a dissolved oxygen concentration meter and a gas detector.

[0021] The ground wire (ground wire) in the single-phase three-wire system provides safe grounding for the equipment. When the equipment leaks or people are electrocuted, the current can flow into the earth through the ground wire, thereby protecting the safety of the equipment and personnel. The ground wire can quickly conduct the leakage current to the earth to prevent the current from accumulating in the equipment or line, reducing the risk of electrical fires. The live wire (phase line) and the zero wire (neutral line) together form a complete circuit to provide a stable power supply for the equipment.

The three-wire system has a clear structure and is easy to identify and maintain. When a fault occurs, the problem can be quickly located and repaired;

[0022] The three-phase five-wire system includes three phase wires, one neutral wire and one ground wire, which provides double grounding protection for three-phase equipment and further improves safety. The neutral wire in the five-wire system can balance the three-phase current, reduce the risk of phase-to-phase short circuit, and protect equipment and lines. Three-phase power supply can provide greater power and more stable current, which is suitable for large equipment or occasions requiring high power output. The five-wire line can be flexibly configured to adapt to different power supply requirements and equipment types. For example, the power supply of one or several phases can be controlled separately to achieve more sophisticated power management. As the demand for electricity increases, the three-phase five-wire line can be easily expanded and upgraded to meet future changes in electricity demand.

[0023] It is further defined that the waste gas treatment box is equipped with a stuffing box located in the air cavity. Such a design, through the physical contact between the gas and the stuffing, can process some substances in the gas that can be converted by the stuffing, such as biological activated carbon stuffing, which can utilize microbial metabolism to convert harmful gases. The stuffing includes but is not limited to honeycomb stuffing, ceramic stuffing, ball rings, Raschig rings, step rings, etc.

[0024] It is further defined that a heat conduction plate is installed in the liquid chamber, and the heat conduction plate is in contact with the inner wall of the ash chamber. Such a design can achieve the heating of the liquid and prevent the liquid inside the liquid chamber used for treating the gas from freezing in a colder environment. Moreover, the temperature increase can also accelerate the reaction efficiency of the liquid and gas to a certain extent.

[0025] It is further specified that a hoist is installed at the input end of the pulverizer, and a gas-liquid separator is connected to the exhaust port output end. With this design, the hoist is conducive to the loading of poultry and livestock carcasses, and the gas-liquid separator realizes gas-liquid separation to prevent the discharge of liquid used to treat gas in the liquid chamber from affecting the surrounding environment or subsequent further processing equipment.

[0026] The beneficial effects of the present invention are as follows:

[0027] The present invention realizes carbonization of dead poultry and livestock carcasses under the effect of the incinerator, achieving the purpose of harmless treatment;

[0028] The present invention crushes the poultry and livestock carcasses by a crusher before cremation, so that the volume of the crushed poultry and livestock carcasses is reduced and easier to burn, thereby shortening the incineration time and improving the processing efficiency of the incinerator;

[0029] The present invention can not only perform carbonization treatment on dead poultry and livestock, but also perform anaerobic fermentation treatment on dead poultry and livestock. Compared with the cremation method, the anaerobic fermentation treatment has less impact on the environment, does not generate smoke and odor, and reduces pollution to the environment. The treated products such as methane gas can be used as clean energy, and organic fertilizer can be returned to the field for use, thus realizing the recycling of resources. The anaerobic fermentation treatment has lower requirements on equipment and relatively low operating costs.

[0030] Under the effect of the conversion mechanism, the present invention can realize whether the poultry and livestock carcasses are finally put into the incinerator or into the anaerobic fermentation box for treatment by controlling the operation of the first telescopic cylinder and the second telescopic cylinder, so that a more economical treatment method can be selected according to the amount of poultry and livestock carcasses, and the use is flexible;

[0031] In the present invention, the anaerobic fermentation box and the incinerator are connected, so the methane produced in the anaerobic fermentation box can assist the incinerator in combustion, and the resources are effectively utilized;

[0059] Preferably, the circuit connections involved in the anaerobic fermentation box 3 and the exhaust gas treatment box 4 are all connected using a unidirectional three-wire system or a three-phase five-wire system. Such a design, a unidirectional three-wire system or a three-phase five-wire system can improve the safety and stability of power supply and prevent the problem of ignition of flammable gas by cremation;

[0060] The ground wire in the single-phase three-wire system provides safe grounding for the equipment. When the equipment leaks or people are electrocuted, the current can flow into the earth through the ground wire, thereby protecting the safety of the equipment and personnel. The ground wire can quickly conduct the leakage current to the earth to prevent the current from accumulating in the equipment or line, reducing the risk of electrical fires. The live wire, phase wire and neutral wire together form a complete circuit to provide a stable power supply for the equipment. The ground wire serves as a safe backup line and does not participate in the normal power supply, but can quickly play a role when needed. The three-wire system has a clear structure and is easy to identify and maintain. When a fault occurs, the problem can be quickly located and repaired;

[0061] The three-phase five-wire system includes three phase wires, one neutral wire and one ground wire, which provides double grounding protection for three-phase equipment and further improves safety. The neutral wire in the five-wire system can balance the three-phase current, reduce the risk of phase-to-phase short circuit, and protect equipment and lines.

As the demand for electricity increases, the three-phase five-wire line can be easily expanded and upgraded to meet future changes in electricity demand. In fact, the line selection of the entire device and measures to prevent electric incineration ignition can also be considered according to specific circumstances.

[0062] Preferably, the waste gas treatment box 4 is equipped with a stuffing box 8 located in the air cavity 401. Such a design can process some substances in the gas that can be converted by the stuffing through the physical contact between the gas and the stuffing, such as biological activated carbon stuffing, which can utilize microbial metabolism to convert harmful gases. The stuffing includes but is not limited to honeycomb stuffing, ceramic stuffing, ball rings, Raschig rings, step rings, etc. In fact, the selection of stuffing for the stuffing box 8 can also be considered according to specific circumstances.

[0063] Preferably, a temperature conducting plate 9 is installed in the liquid chamber 402, and the temperature conducting plate 9 is in contact with the inner wall of the ash chamber 106. Such a design can achieve the heating of the liquid and prevent the liquid used for treating the gas inside the liquid chamber from freezing in a colder environment. Moreover, the temperature increase can also accelerate the reaction efficiency of the liquid and the gas to a certain extent. In fact, measures for controlling and heating the temperature of the liquid in the liquid chamber 402 can also be considered according to specific circumstances.

[0064] Preferably, a hoist is installed at the input end of the pulverizer 2, and a gas-liquid separator is connected to the output end of the exhaust port 411. With this design, the hoist is conducive to the loading of poultry and livestock carcasses, and the gas-liquid separator realizes gas-liquid separation, preventing the discharge of liquid used to treat gas in the liquid chamber from affecting the surrounding environment or subsequent further processing equipment. In fact, the choice of loading method and exhaust gas treatment measures can also be considered according to specific circumstances.

[0065] In this implementation case, when using a harmless treatment device for dead livestock carcasses, anaerobic fermentation treatment or incineration treatment is selected according to the amount of livestock carcasses to be treated. If anaerobic fermentation treatment is used, the demand can be met, and compared with incineration treatment, energy consumption can be saved to a certain extent;

[0066] When using anaerobic fermentation treatment, the inclined baffle 501 is completely located in the inclined slot 209, blocking it directly below the grinder 2, and then the straight baffle 502 rises to open the through slot 210. The movement of the inclined baffle 501 is achieved by controlling the first telescopic cylinder 504, and the movement of the straight baffle 502 is achieved by controlling the second telescopic cylinder 505. In this state, the poultry and livestock carcasses crushed by the grinder 2 will slide under their own weight from the slope of the inclined baffle 501 through the through slot 210 into the anaerobic fermentation box 3 for anaerobic fermentation treatment. It should be noted that before or during anaerobic fermentation, materials can be added to the fermentation box 3, and the materials include but are not limited to livestock and poultry manure, straw and rice bran. Moreover, during the fermentation period, the fermented materials can also be taken out from the anaerobic fermentation box 3 and used as fertilizer to expand the scope of use. Further explanation: the bottom of the anaerobic fermentation box 3 can be placed underground, so the size of its internal space is not limited to ensure the anaerobic fermentation treatment capacity;

[0067] When using cremation treatment, the inclined baffle 501 is not located in the inclined slot 209, and the area directly below the crusher 2 is cleared. The straight baffle 502 is completely lowered to block the slot 210. The movement of the inclined baffle 501 is achieved by controlling the first telescopic cylinder 504, and the movement of the straight baffle 502 is achieved by controlling the second telescopic cylinder 505. In this state, the crushed poultry and livestock carcasses fall into the circular combustion chamber 101 under their own weight. Adding a combustion source inside the circular combustion chamber 101 can cause the inside of the circular combustion chamber 101 to burn, thereby achieving the purpose of cremation. The carbonized ash falls into the ash hopper 107 through the ash leakage hole 105 for subsequent treatment, and the ash hopper 107 can also be removed and directly discharged from the ash outlet 108 for subsequent treatment. During the cremation period, the motor 103 is controlled to run, which can stir the fragments of the poultry and livestock carcasses inside to improve the cremation efficiency and degree. During the cremation period, the electronically controlled one-way air valve 303 is controlled to open, which can introduce the methane generated during the fermentation process in the anaerobic fermentation box 3 into the circular combustion chamber 101, so as to achieve the purpose of combustion-supporting, and ensure that the carbonization temperature reaches the standard and the cremation efficiency;

[0068] The gas generated by cremation accumulates inside and fills into the gas cavity 401 under air pressure. The negative pressure pump 403 is started to send the gas into the liquid cavity 402 through the air pipe 404. The gas delivery by the negative pressure pump 403 is to ensure the airtightness of the circular combustion cavity 101 and ensure sufficient combustion, because the circular combustion cavity 101 is not in a closed state when the negative pressure pump 403 is running.

[0069] The liquid used for gas treatment in the liquid cavity 402 includes but is not limited to sodium hypochlorite and sodium hydroxide. During the neutralization period, the liquid pump 405 can be started to send the liquid into the water pipe 406. After being diverted by the flow equalizer 407, the liquid is sprayed out from the nozzle 408 for spraying treatment to ensure that the gas discharged from the exhaust port 411 meets the emission requirements.

[0070] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
