Description

Technical Field

[0001] The present invention relates to the field of fermentation of various animal carcasses, and particularly to a fermentation treatment device and a fermentation treatment method for various animal carcasses. Background Art

[0002] The carcasses of animals after death often carry various germs. If not treated or treated improperly, the carcasses will quickly decompose and rot, emitting stinks, contaminating the air, water source and soil with pathogenic microorganisms, affecting people's living environment, and even causing the spread of diseases.

[0003] The most traditional methods for dealing with animal carcasses are direct landfill or cremation. After the animal carcasses are landfilled, problems such as decomposition and rotting, emitting stinks, and contaminating the air, water source and soil with pathogenic microorganisms will inevitably occur. For cremation, it directly results in the consumption of fuel and a large amount of carbon emissions, which is not conducive to environmental protection.

[0004] Therefore, at present, there has emerged on the market a method of using high-temperature biodegradation to treat animal carcasses and finally prepare organic fertilizers. However, this method is very energy-consuming, goes against the concept of environmental protection, and cannot achieve centralized management. Summary of the Invention

[0012] As a further improvement of the present invention, the rotation driving mechanism includes a motor arranged on the tank body base and electrically connected to the central controller, a transmission shaft connected to the output shaft of the motor, and at least one transmission roller sleeved on the periphery of the transmission shaft and in contact with the outer wall of the tank.

[0013] As a further improvement of the present invention, an exhaust structure is arranged at one end of the inner side of the tank close to the exhaust port. The exhaust structure includes a baffle arranged in the tank body and a partition arranged in the tank body and located between the baffle and the exhaust port. An exhaust cavity is formed between the partition and the exhaust port. An inner exhaust port is opened on the baffle. An upper exhaust through hole and a lower exhaust through hole are formed between the partition and the inner wall of the tank. An upper exhaust channel communicating between the inner exhaust port and the upper exhaust through hole and a lower exhaust channel communicating between the inner exhaust port and the lower exhaust through hole are respectively formed between the baffle and the partition; at the same time, an upper movable baffle swinging in the upper exhaust channel and a lower movable baffle swinging in the lower exhaust channel are respectively arranged on the inner exhaust port.

[0014] As a further improvement of the present invention, the tank body is mainly composed of a lower tank body and an upper cover covering the lower tank body. An open input port is provided at the upper end of the lower tank body. The upper cover covers the open input port. At the same time, several hanging hooks are arranged on the upper cover.

[0015] As a further improvement of the present invention, the waste gas treatment device includes a waste gas treatment tank, a plurality of waste gas ventilation pipes connected between the front end of the waste gas treatment tank and several fermentation tanks, and a negative pressure exhaust fan arranged at the rear end of the waste gas treatment tank. Among them, an active bacteria bed is arranged on the front side inside the waste gas treatment tank, and activated carbon is filled on the rear side; an electric heating component is arranged in the waste gas ventilation pipe; a solar photovoltaic panel for supplying power to the heating component, the electric heating component and the negative pressure exhaust fan is arranged on the centralized treatment bin.

[0016] The method for fermenting and treating animal carcasses based on the above equipment is characterized by including the following steps:

[0017] (1) Put a single animal carcass into a numbered fermentation tank, add fermentation bacteria and fillers, and cover the fermentation tank;

[0018] (2) Lift the fermentation tank onto the corresponding position in the centralized treatment bin;

[0019] Connect the waste gas ventilation pipe of the waste gas treatment device to the exhaust port of the fermentation tank, and connect the ventilation pipe on the fermentation tank to the external air supply device;

[0020] (3) Control the ventilation pipe to introduce air into the tank body through the central controller, and control the heating component inside the tank body to work, heating the temperature inside the tank body to 60°C - 70°C; at the same time, the central controller controls the rotation driving mechanism to drive the tank body to rotate at a slow speed for 10 - 30 days; during the rotation of the tank body, the fermentation bacteria inside the tank body completely decompose and corrupt the animal carcass, generating bioenergy conversion and decomposition, forming organic fertilizer and waste gas, and the waste gas is discharged from the exhaust port to the waste gas treatment device;

[0021] (4) The waste gas treatment device purifies the waste gas and finally discharges it into the external environment.

[0022] As a further improvement of the present invention, step (4) further includes the following steps: The temperature sensor detects the temperature inside the tank body in real time and transmits the detection result to the central controller in real time. When it is detected that the temperature inside the tank body exceeds 70°C, the central controller disconnects the power supply to the heating component, and the heating component stops working; when it is detected that the temperature inside the tank body is lower than 60°C, the central controller reconnects the power supply to the heating component, and the heating component starts working; continuously repeat this step to keep the temperature inside the tank body at 60°C - 70°C.

[0023] The beneficial effects of the present invention are:

[0024] (1) By designing a centralized treatment bin that can accommodate several fermentation tanks, several fermentation tanks are vertically integrated, reducing the floor area occupied by the fermentation tanks. Multiple animal carcasses can be fermented separately at the same time to obtain separate organic fertilizers, which facilitates the handling of animal carcasses when people encounter them, provides great convenience for people to handle various animal carcasses, and reduces costs. Moreover, it is conducive to centralized control and management of several fermentation tanks;

[0025] (2) Due to the special structural design of the internal array of heating components and the internal array of gas supply components in the fermentation tank, it provides appropriate temperature and oxygen for the fermentation process inside the tank, which is conducive to the more complete decomposition and corruption of the animal carcasses inside, and finally forms organic fertilizers, achieving both the purpose of energy conservation and carbon reduction and the regeneration of energy;

[0026] (3) The waste gas generated after the fermentation treatment of multiple fermentation tanks is treated by a waste gas treatment device. The active bacteria bed adsorbs the toxic components, odors, etc. in the waste gas to complete the first-stage waste gas treatment process. Then, the remaining pollutants in the waste gas are adsorbed by activated carbon to separate the pollutants from the gas, obtaining colorless, odorless and clean gas. Finally, it is discharged into the environment, and the waste gas treatment is complete and thorough, harmless to the environment and the human body;

[0027] (4) By controlling the temperature of the fermentation process in real time, the temperature inside the tank is maintained at 60°C - 70°C, which is conducive to the decomposition of animal carcasses by the internal fermentation bacteria;

[0028] (5) By controlling the rotation speed of the fermentation tank, which rotates 2 - 3 circles a day, not only is the power consumption low, energy-saving and environmentally friendly; but also due to the rotation of the fermentation tank, the animal carcasses, fermentation bacteria and fillers inside the fermentation tank can be continuously turned over, realizing the internal oxygen supplement, accelerating the entire aerobic bacteria fermentation process, improving the fermentation efficiency, and thus improving the turnover rate of each fermentation tank.

[0029] (6) The entire equipment has low current consumption, and solar power supply can be adopted to achieve the purpose of energy conservation and environmental protection.

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following details the specific embodiments of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0041] Please refer to Figures 1 to 3 , an embodiment of the present invention provides a fermentation treatment device for various animal carcasses, including a central controller, a centralized treatment bin 1, several fermentation tanks 2 arranged in the centralized treatment bin 1, and at least one waste gas treatment device 3 connected to the several fermentation tanks 2. Among them, the fermentation tank 2 includes a tank body base 21, a tank body 22 arranged on the tank body base 21, and a rotation driving mechanism 23 that drives the tank body 22 to rotate and is electrically connected to the central controller. On the inner wall of the tank body 22, several groups of heating components 24 and several groups of air supply components 25 controlled by the central controller are respectively distributed. The several groups of heating components 24 heat the fermentation process in the tank body 22, and the several groups of air supply components 25 provide oxygen for the fermentation process in the tank body 22, facilitating the decomposition and corruption of the internal animal carcasses to be more complete and thorough. At the same time, a temperature sensor electrically connected to the central controller is arranged in the tank body 22 to facilitate real-time detection and understanding of the temperature in the tank body 22 and facilitate the control of the internal heating temperature; and an exhaust port 221 communicating with the waste gas treatment device 3 is provided at the rear end of the tank body 22. After fermentation is completed, the generated waste gas is discharged from the exhaust port 221, and finally the waste gas treatment device purifies the waste gas and finally discharges it to the external environment.

[0042] In this embodiment, there are several positions in the centralized processing bin 1 for placing the fermentation tanks 2. After the fermentation tanks 2 are placed in the positions, several fermentation tanks 2 are integrated into one, enabling the simultaneous individual fermentation treatment of multiple corpses to obtain individual organic fertilizers. This provides great convenience for people to handle animal corpses when encountering them, and also reduces costs. At the same time, the central controller can perform automated centralized control over the operation of several fermentation tanks 2. Specifically, it controls the rotation speed of the fermentation tank 2, the internal heating temperature, and the supply of air (oxygen) into the tank body 22.

[0043] Specifically, as Figure 3 shown in Figure 4 Figure [not provided], the heating component 24 includes a heating structure 241 distributed along the inner wall of the tank body 22 in the length direction of the tank body 22, and at least one heating element 242 distributed inside the heating structure 241 in the length direction of the heating structure 241. Among them, for the power supply of the heating element 242, a wired power transmission method or a microwave wireless power transmission method can be adopted. No matter which method is used, as long as it can make the heating element 242 generate heat and increase the temperature inside the tank body 22. Specifically, the heating structure 241 can be a heating tube, and the heating element 242 can be a heating wire. Specifically, the wired power transmission method is to directly connect the heating element 242 to the central controller through a power supply wire for power supply; the microwave wireless power transmission method is to be powered by a microwave wireless power transmission device communicating with the central controller.

[0044] Regarding the structure of the heating component 24, it also includes a printed copper foil attached to the inner wall of the tank body 22, and the printed copper foil is connected to the central controller through an energized wire for power supply, or is powered by a microwave wireless power transmission device communicating with the central controller. The printed copper foil generates heat through energization to uniformly heat the inside of the tank body 22, thereby increasing the temperature inside the tank body 22.

[0045] At the same time, the air supply component 25 includes an air pipe 251 provided on the inner wall of the tank body 22 and arranged side by side with the heating structure 241. Several air holes 2511 are formed on the side wall of the air pipe 251, as Figure 4 shown in

[0046] When specifically installing the heating component 24 and the air supply component 25, in this embodiment, several strip-shaped grooves 222 for the heating component 24 and the air supply component 25 to be embedded are formed on the inner wall of the tank body 22. As Figure 5 shown in Figure 6 figure, at the same time, a heat insulation layer 223 is provided on the inner wall of the tank body 22, which is conducive to preventing the heat inside the tank body 22 from dissipating.

[0047] In order to accelerate the decomposition speed of the animal carcass, in this embodiment, several conical breaking protrusions 224 are convexly provided on the inner wall of the tank body 22. As Figure 7 shown in figure, during the rotation of the tank body 22, the several conical breaking protrusions 224 collide and break the animal carcass and the filler, thereby accelerating the decomposition speed.

[0048] In this embodiment, as Figure 2 shown in figure, the rotation driving mechanism 23 includes a motor 231 arranged on the base of the tank body 22 and electrically connected to the central controller, a transmission shaft 232 connected to the output shaft of the motor 231, and at least one transmission roller 233 sleeved on the periphery of the transmission shaft 232 and in contact with the outer wall of the tank body 22. The start and stop of the motor 231 are controlled by the central controller. The motor 231 drives the transmission shaft 232 to rotate. The rotation of the transmission shaft 232 drives the transmission roller 233 to rotate, and the rotation of the transmission roller 233 causes the tank body 22 to rotate.

[0049] In this embodiment, as Figure 8 shown in figure, an exhaust structure 225 is provided at one end of the inner side of the tank body 22 close to the exhaust port 221. Specifically, the exhaust structure 225 includes a baffle 2251 arranged in the tank body 22 and a partition 2252 arranged in the tank body 22 and located between the baffle 2251 and the exhaust port 221. An exhaust cavity 2253 is formed between the partition 2252 and the exhaust port 221. An inner exhaust port 22511 is opened on the baffle 2251. An upper exhaust through hole 2254 and a lower exhaust through hole 2255 are formed between the partition 2252 and the inner wall of the tank body 22. An upper exhaust channel 2256 communicating between the inner exhaust port 22511 and the upper exhaust through hole 2254 and a lower exhaust channel 2257 communicating between the inner exhaust port 22511 and the lower exhaust through hole 2255 are respectively formed between the baffle 2251 and the partition 2252. At the same time, an upper movable shutter 2258 swinging in the upper exhaust channel 2256 and a lower movable shutter 2259 swinging in the lower exhaust channel 2257 are respectively arranged on the inner exhaust port 22511.

[0050] In this embodiment, the upper movable baffle 2258 and the lower movable baffle 2259 are movable baffles that can swing freely. That is, when the tank body 11 rotates to a position where the upper movable baffle 2258 is above the lower movable baffle 2259, the upper movable baffle 2258 swings downward to connect the inner exhaust port 22511 with the upper exhaust passage 2256. That is, the upper movable baffle 2258 is in an open state, and the waste gas can pass through. And the lower movable baffle 2259 just abuts against the partition plate 2252, that is, the lower movable baffle 2259 is in a closed state, preventing the inner exhaust port 22511 from communicating with the lower exhaust passage 2257, and the waste gas cannot pass through. When the tank body 11 continues to rotate until the upper movable baffle 2258 is below the lower movable baffle 2259, similarly, the lower movable baffle 2259 swings downward to connect the inner exhaust port 22511 with the lower exhaust passage 2257. That is, the lower movable baffle 2259 is in an open state, and the waste gas can pass through. And the upper movable baffle 2258 just abuts against the partition plate 2252, that is, the upper movable baffle 2258 is in a closed state, preventing the inner exhaust port 22511 from communicating with the upper movable baffle 2258, and the waste gas cannot pass through. Thus, the waste gas is always discharged from the upper exhaust passage inside the tank body, while the lower exhaust passage is blocked, preventing internal substances from entering or even blocking the lower exhaust passage.

[0051] When the waste gas generated by fermentation enters the upper exhaust passage, it enters the exhaust cavity 2253 through the exhaust through holes on the upper side, and finally is discharged to the waste gas treatment device 3 through the exhaust port 221.

[0052] In this embodiment, as Figure 1 shown, the waste gas treatment device 3 includes a waste gas treatment tank 31, a plurality of waste gas ventilation pipes 32 connected between the front end of the waste gas treatment tank 31 and several fermentation tanks 2, and a negative pressure exhaust fan 33 arranged at the rear end of the waste gas treatment tank 31. Among them, an active bacteria bed is arranged on the front side inside the waste gas treatment tank 31, and activated carbon is filled on the rear side. Specifically, the active bacteria bed is mainly composed of several microbial beds stacked up and down, and a biofilm is arranged inside the microbial bed. Specifically, the biofilm includes a plastic carrier, and wood chips and microbial active bacteria filled in the plastic carrier.

[0053] The waste gas entering the waste gas treatment device 3 enters the waste gas treatment tank 31 through the waste gas ventilation pipe 32, and then the biofilm in the active bacteria bed in the waste gas treatment tank 31 adsorbs the toxic components, odors, etc. in the waste gas, completing the first-stage waste gas treatment process. Then, the waste gas after the first-stage treatment passes through the activated carbon, and the pollutants in the waste gas are adsorbed on the surface of the activated carbon, separating the pollutants from the gas, and obtaining a colorless, odorless and clean gas. Finally, it is led to the environment by the negative pressure exhaust fan 33, and the waste gas treatment is complete and thorough, without harm to the environment and the human body.

[0054] To prevent steam condensation inside the exhaust gas ventilation pipe 32, in this embodiment, an electric heating component 321 is provided inside the exhaust gas ventilation pipe 32. Specifically, the electric heating component 321 can be an electric heating wire. When the electric heating component 321 is energized to generate heat, it appropriately heats the inside of the exhaust gas ventilation pipe 32, raises the internal temperature, and achieves the purpose of effectively preventing steam condensation.

[0055] To achieve the purpose of energy conservation, in this embodiment, the solar heat is reasonably utilized. A solar photovoltaic panel 4 is provided on the centralized treatment bin 1 to supply power to the heating component 24, the electric heating component 321, and the negative pressure exhaust fan 33 respectively. The solar photovoltaic panel 4 absorbs the solar heat and converts it into electrical energy to supply power to the entire equipment system.

[0056] To facilitate putting the animal carcass, filler, and fermentation bacteria into the tank body 22, as Figure 9 shown, the tank body 22 of this embodiment mainly consists of a lower tank body 226 and an upper cover 227 covering the lower tank body 226. An open input port 2261 is provided at the upper end of the lower tank body 226, and the upper cover 227 covers the open input port 2261. The animal carcass, filler, and fermentation bacteria are put in from the open input port 2261. At the same time, a number of hanging hooks 2271 are provided on the upper cover 227 to facilitate the automatic lifting of the entire fermentation tank 2.

[0057] To ensure the sealing performance of the tank body 22 after the upper cover 227 covers the lower tank body 226, in this embodiment, a sealing ring is provided at the edge of the upper end face of the lower tank body 226 to make the upper cover 227 and the lower tank body 226 closely combined, and then the upper cover 227 is fixed to the lower tank body 226 by means of screws or the like.

[0058] The embodiment of the present invention also discloses an animal carcass fermentation treatment method based on the above equipment, including the following steps:

[0059] (1) Put a single animal carcass into the numbered fermentation tank 2, and put in fermentation bacteria and filler. The filler can be wood chips or the like, and cover the fermentation tank 2.

[0060] (2) Lift the fermentation tank 2 onto the corresponding position in the centralized treatment bin 1. An automated device can be used to lift the fermentation tank 2 to the position of the centralized treatment bin 1, and then it is pushed into the corresponding position by automated conveying or a robotic arm.

[0061] (3) Connect the exhaust gas ventilation pipe of the exhaust gas treatment device to the exhaust port of the fermentation tank, and connect the ventilation pipe on the fermentation tank to the external air supply device.

[0062] (4) The central controller controls the air pipe to introduce air into the tank body, and controls the heating component inside the tank body to work, heating the temperature inside the tank body to 60°C - 70°C; meanwhile, the central controller controls the rotation drive mechanism to drive the tank body to slowly rotate at a speed of 0.083 - 0.125 r / h for 10 - 30 days; during the rotation of the tank body, the fermentation bacteria inside the tank body completely decompose and corrupt the animal carcasses, generating bioenergy conversion and decomposition, forming organic fertilizer and waste gas, and the waste gas is discharged from the exhaust port to the waste gas treatment device;

[0063] (5) The waste gas treatment device purifies the waste gas and finally discharges it into the external environment.

[0064] The step (4) further includes the following steps: The temperature sensor detects the temperature inside the tank in real time and transmits the detection result to the central controller in real time. When it is detected that the temperature inside the tank body exceeds 70°C, the central controller disconnects the power supply to the heating component, and the heating component stops working; when it is detected that the temperature inside the tank body is lower than 60°C, the central controller powers on the heating component again, and the heating component starts to work; this step is continuously repeated to keep the temperature inside the tank body at 60°C - 70°C.

[0065] Of course, in this embodiment, a corresponding thermometer 5, hygrometer 6 and time recorder 7 can also be set on the front end of the tank body 22 of the fermentation tank 2. The thermometer 5 and the hygrometer 6 are inserted into the tank body 22, as Figure 9 shown, so that the staff can view the temperature, humidity and fermentation time inside the tank body 22 in real time.

[0066] The various types of animal carcass fermentation treatment equipment provided in this embodiment can be combined with the stereoscopic warehouse technology to realize the automatic control and management of multiple fermentation tanks with codes or labels, so as to achieve the following advantages:

[0067] (1) Automatic operation, improving efficiency, and realizing the automatic storage and retrieval of fermentation tanks;

[0068] (2) Precise warehouse data management, solving the problem of inaccurate data, reducing errors, and performing warehouse management more precisely;

[0069] (3) Accurate query of real-time dynamic inventory information, and data processing saving manpower;

[0070] (4) Saving storage space, realizing the rationalization of the upper floors of the warehouse, automatic storage and retrieval, and simple operation.

[0071] (5) Saving energy and reducing carbon emissions.

A method for fermenting and treating animal carcasses based on the device according to any one of claims 1 to 8, characterized in that, It includes the following steps: (1) Put a single animal carcass into a numbered fermentation tank, add fermentation bacteria and fillers, and cover the fermentation tank; (2) Place the fermentation tank on the corresponding position in the centralized treatment bin; (3) Connect the waste gas ventilation pipe of the waste gas treatment device to the exhaust port of the fermentation tank, and connect the ventilation pipe on the fermentation tank to the external air supply device; (4) Control the ventilation pipe to introduce air into the tank body through the central controller, and control the heating component inside the tank body to work, heating the temperature inside the tank body to 60°C - 70°C; at the same time, the central controller controls the rotation drive mechanism to drive the tank body to rotate at a slow speed for 10 - 30 days; during the rotation of the tank body, the fermentation bacteria inside the tank body completely decompose and corrupt the animal carcass, generating bioenergy conversion and decomposition, forming organic fertilizer and waste gas, and the waste gas is discharged from the exhaust port to the waste gas treatment device; (5) The waste gas treatment device purifies the waste gas and finally discharges it to the external environment.

10. The method for fermenting and treating animal carcasses according to claim 9, characterized in that, The step (4) further includes the following steps: The temperature sensor detects the temperature inside the tank body in real time and transmits the detection result to the central controller in real time. When it is detected that the temperature inside the tank body exceeds 70°C, the central controller disconnects the power supply to the heating component, and the heating component stops working; when it is detected that the temperature inside the tank body is lower than 60°C, the central controller supplies power to the heating component again, and the heating component starts to work; continuously repeat this step to keep the temperature inside the tank body at 60°C - 70°C.
