Description

Technical Field

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

[0002] In life, many pet owners will encounter the situation of pet death. Whether it is a normally dead or diseased dead animal carcass, if not treated or treated improperly, the carcass will quickly decompose and rot, emitting stench. Therefore, it is necessary to decompose and treat the pet carcass in a correct way.

[0003] The patent with the publication number CN105107817B discloses an animal carcass decomposition and fermentation device, including a feeding hopper, a pulverizer, and a fermentation tank. The feeding hopper includes a feeding hopper main body. The pulverizer includes a roller, a cutter, a snap ring, a cutter groove, and a motor. The fermentation tank includes a fermentation tank body, a stirring device, and a stirring motor. The above patent can prevent the scattering of residues during the treatment of animal carcasses, improve work efficiency, make the fermentation reaction more sufficient, reduce the re-generation of pollution sources, and enable the animal carcass to be fully fermented in the fermentation tank, preventing secondary pollution caused by incomplete fermentation.

[0004] However, since most pet owners cannot accept the pulverization of animal carcasses, they will choose alkaline hydrolysis for decomposition. Alkaline hydrolysis means decomposing the carcass into amino acids, polypeptides, and sterile liquid in an alkaline solution under high temperature and high pressure. However, the existing device directly puts the carcass in and then sprays water. Since the position of the carcass is fixed, when introducing the alkaline solution, it cannot effectively and evenly contact the solution, resulting in low hydrolysis efficiency and inability to efficiently decompose animal carcasses. Summary of the Invention

The pulling cover is fixedly connected to one end of the placement basket close to the installation opening. The two slide rails are symmetrically and fixedly installed at the bottom of the decomposition tank. The two sliding blocks are symmetrically and fixedly connected to the side of the placement basket away from the pulling cover and are slidably arranged inside the slide rails. The slide rails are arranged in an inverted U shape for impurities to move to the bottom end of the decomposition tank.

[0008] Preferably, the rotating blade is a trapezoidal blade, with the short side fixedly connected to the driving gear ring and the other end fixedly connected to the driving ring. The rotating blade is inclined to form a frustum-shaped rotating wheel.

[0009] Preferably, the driving assembly includes a rotating gear ring, a first driving gear, and a fixing ring. The rotating gear ring is rotatably installed between the driving gear ring and the placement basket. The fixing ring is fixedly connected to the upper sides of the driving gear ring and the placement basket for connection and fixation. The first driving gear is arranged at the bottom of the decomposition tank and is meshed with the driving gear ring.

[0010] Preferably, the first driving gear is installed at the bottom of the decomposition tank through a control assembly. The control assembly includes a driving motor, a control gear, a waterproof cover, two telescopic rods, a rotating rod, and a second driving gear. The driving motor is fixedly connected to the bottom of the decomposition tank through a placement rack. The control gear is fixedly connected to the driving end of the driving motor. The two telescopic rods are respectively fixedly connected to both sides of the bottom end of the decomposition tank. The two ends of the rotating rod are respectively rotatably installed at the tops of the two telescopic rods. The second driving gear is fixedly connected to the rotating rod and is meshed with the control gear. The waterproof cover is arranged outside the second driving gear and is sealingly and rotatably connected to the rotating rod. The first driving gear is sleeved on the rotating rod.

[0011] Preferably, a guiding arc plate is arranged at the bottom of the decomposition tank. The guiding arc plate is a semi-circular arc plate. A guiding assembly is arranged on the rotating rod, and the guiding assembly is used to guide out the decomposed impurities.

[0012] Preferably, the guiding assembly includes a guiding spiral blade and a guiding-out box.

The guiding-out box is arranged on the side of the decomposition tank close to the control console and is communicated with the guiding plate.

[0013] Preferably, an ultrasonic probe is fixedly connected to the side of the console close to the placement basket. A bayonet is provided on one side of the placement basket close to the console, and the ultrasonic probe is clamped inside the bayonet.

[0014] Preferably, two water pipes are symmetrically and fixedly installed on both sides of the decomposition tank.

The mounting frames are located above the placement opening of the placement basket, and a plurality of liquid spray heads are fixedly connected to the bottom of the mounting frames.

[0015] A decomposition method using the above-mentioned animal carcass decomposition device, the decomposition steps include: S1: Place the carcass to be decomposed into the placement basket, and then transfer the placement basket into the decomposition tank to prepare for decomposition; S2: The first stage: Alkaline protease treatment. Control the activity of alkaline protease at 37 - 55 °C and the pH value at 8 - 10 to ensure the highest activity. Alkaline protease has higher activity in an environment with a lower ionic strength. Through alkaline protease, proteins can be decomposed to make the carcass into smaller peptide segments and amino acids, facilitating subsequent processing; S3: The second stage: Alkaline lipase treatment. Through alkaline lipase, fats can be decomposed and converted into substances that are more easily utilized by organisms. At this time, keeping the temperature at about 37 - 55 °C has the highest activity, and the pH value is controlled within the range of 8 - 11 to ensure the highest activity; S4: The third stage: Saponification reaction. Through the saponification reaction, fats react with alkalis to generate higher fatty acid salts and glycerol. This is an important step in the biological decomposition process. The higher fatty acid salts and glycerol generated by the saponification reaction can improve biodegradability and make the substances after biological decomposition more easily absorbed by the environment; S5: The fourth stage: Mixture treatment. Through chemical reactions, such as acid-base neutralization and oxidation-reduction, harmful substances in the mixture are converted into harmless substances to reduce environmental pollution; S6: The fifth stage: Inorganic bone treatment. Use chemical substances such as strong acids or strong alkalis to dissolve or decompose the bones to convert them into inorganic substances; S7: During the entire treatment stage, control the rotating assembly to rotate through the driving motor, thereby driving the animal carcass placed inside the rotating assembly to rotate, improving the decomposition efficiency, and at the same time accelerating the decomposition by turning on the ultrasonic probe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When an animal carcass is placed inside the placement basket, the driving component drives the first transmission gear ring to rotate, thereby driving multiple rotating blades to rotate, ensuring that the animal carcass is in a flipped state during the decomposition process, improving the full contact between the animal carcass and the solution when the solution is less, and the present invention can increase the contact area between the gas storage for solution introduction and the solution of the carcass, thereby improving the hydrolysis efficiency and efficiently hydrolyzing the carcass; 2. Since the temperature of the alkaline solution near the heating position is higher than that of other positions, the rotating wheel drives the alkaline solution to stir, which can accelerate the uniform heating speed of the alkaline solution, thereby ensuring the temperature of the alkaline solution at the contact position of the carcass and ensuring the uniform hydrolysis of the carcass; 3. The rotating second driving gear drives the rotating rod to rotate, thereby rotating the material guiding spiral blade, gradually pushing the impurities falling into the material guiding arc plate to one side, and finally dropping and accumulating inside the export box. Then, the export box transfers and reprocesses these impurities, which can improve the overall processing and decomposition efficiency; 4. A driving motor drives the rotating component and the material guiding component to work simultaneously, optimizing the overall structure, reducing energy consumption while ensuring the decomposition effect; 5. In order to improve the decomposition efficiency, ultrasonic probes are provided. Ultrasonic waves generate high-frequency vibrations in the alkaline solution to form microbubbles, promoting its rapid reaction with the alkali solution, which can shorten the hydrolysis time by 30%-50%, especially having a significant effect on difficult-to-decompose connective tissues (such as fascia and cartilage); 6. The ultrasonic cavitation effect can physically break through the envelopes of bacteria and viruses. Combining with the high pH value of the alkaline environment, it realizes dual inactivation, and the pathogen killing rate is close to 100%. The ultrasonic vibration eliminates the layering phenomenon between the alkali solution and the carcass, ensuring that the solution fully contacts the inside of the tissue and avoiding local undecomposed residues.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of clear narration, rather than to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present invention.

[0021] Refer to Figures 1-10 , a decomposition device for animal carcasses, including: a decomposition tank 1, a side cover 2 rotatably arranged on the decomposition tank 1, and a control console 3 fixedly installed on the side end of the decomposition tank 1. The cross-section of the decomposition tank 1 is oval, and an installation opening is provided on the side away from the control console 3. A placement component 4 is arranged inside the installation opening, and the placement component 4 is used for placing animal carcasses; The placing assembly 4 comprises a placing basket 41, which is a horizontally arranged cylindrical basket with a placing opening on the upper surface. A rotating assembly 5 is arranged inside the placing basket 41, and the rotating assembly 5 is used to rotate the animal carcass; The rotating assembly 5 includes a driving gear ring 51, a driving ring 52 and a plurality of rotating pieces 53. The driving gear ring 51 is rotatably mounted on a side of the placement basket 41 away from the console 3, the driving ring 52 is rotatably mounted on the other end of the placement basket 41, and the plurality of rotating pieces 53 are annularly fixedly connected between the driving gear ring 51 and the driving ring 52. A driving assembly 6 is disposed below the placement basket 41 , and the driving assembly 6 is used to drive the rotating assembly 5 to rotate.

[0022] In the embodiment of the application of the above technical solution, a heating device is provided inside the decomposition tank 1 for changing the temperature of the solution inside the decomposition tank 1. At the same time, an observation window is provided on the side cover 2 for observing the internal decomposition situation. When the animal carcass is placed inside the placement basket 41, the driving assembly 6 drives the gear ring 51 to rotate, thereby driving the multiple rotating plates 53 to rotate, ensuring that the animal carcass is in a flipped state during the decomposition process, thereby improving the full contact between the animal carcass and the animal carcass when the solution is less.

[0023] The present invention can increase the contact area between the stored gas and the solution when the corpse is introduced into the solution, thereby improving the efficiency of hydrolysis and performing efficient hydrolysis on the corpse.

[0024] The preferred technical solution in this embodiment is: Reference Figures 3-7 The placement component 4 also includes two slide rails 42, two sliding blocks 43 and a pull cover 44. The pull cover 44 is fixedly connected to one end of the placement basket 41 close to the installation port. The two slide rails 42 are symmetrically fixedly installed at the bottom of the decomposition tank 1. The two sliding blocks 43 are symmetrically fixedly connected to the side of the placement basket 41 away from the pull cover 44, and are slidably arranged inside the slide rails 42. The slide rails 42 are arranged in an inverted U shape, which is used to move impurities to the bottom of the decomposition tank 1.

[0025] When placing an animal carcass, the placing basket 41 is removed from the decomposition tank 1 by pulling the pull cover 44, and the animal carcass is placed inside the decomposition tank 1. The pull cover 44 is then pushed to transfer the carcass into the decomposition tank 1 for hydrolysis. This method can quickly transfer the carcass and improve the efficiency of hydrolysis.

[0026] Reference Figures 8-9 The rotating piece 53 is a trapezoidal piece, and the short side is fixedly connected to the driving gear ring 51, and the other end is fixedly connected to the driving ring 52. The rotating piece 53 is tilted to form a truncated cone-shaped rotating wheel.

[0027] There is enough space between the rotating pieces 53. Since the end of the rotating piece 53 close to the driving gear ring 51 is shorter, there is enough space to put the animal carcass. When the rotating wheel rotates under the drive of the driving gear ring 51, the animal carcass will rotate with the rotating wheel. When the aqueous solution is continuously introduced, all surfaces of the carcass are in full contact with the solution, so that the animal carcass continues to roll in the alkaline solution, thereby improving the hydrolysis efficiency of the animal carcass.

[0028] At the same time, since the alkaline solution will be heated inside the decomposition tank 1, but the temperature of the alkaline solution near the heating position will be higher than that at other positions, the rotating wheel will drive the alkaline solution to be stirred, which can speed up the uniform heating of the alkaline solution, thereby ensuring the temperature of the alkaline solution at the position where the corpse is in contact, and ensuring uniform hydrolysis of the corpse.

[0029] Reference Figures 4-5 The driving assembly 6 includes a rotating gear ring 61, a first driving gear 62 and a fixed ring 63. The rotating gear ring 61 is rotatably installed between the driving gear ring 51 and the placement basket 41. The fixed ring 63 is fixedly connected to the driving gear ring 51 and the upper side of the placement basket 41 for connection and fixing. The first driving gear is arranged at the bottom of the decomposition tank 1 and is meshed with the driving gear ring 51. The first driving gear 62 is installed at the bottom of the decomposition tank 1 through the control component 7. The control component 7 includes a driving motor 71, a control gear 72, a waterproof cover 73, two telescopic rods 74, a rotating rod 75 and a second driving gear 76. The driving motor 71 is fixedly connected to the bottom of the decomposition tank 1 through a placement frame. The control gear 72 is fixedly connected to the driving end of the driving motor 71. The two telescopic rods 74 are respectively fixedly connected to the two sides of the bottom end of the decomposition tank 1. The two ends of the rotating rod 75 are respectively rotatably installed on the top of the two telescopic rods 74. The second driving gear 76 is fixedly connected to the rotating rod 75 and meshed with the control gear 72. The waterproof cover 73 is arranged on the outside of the second driving gear 76 and is sealed and rotatably connected with the rotating rod 75. The first driving gear 62 is sleeved on the rotating rod 75.

[0030] The bottom side of the fixing ring 63 is provided with an opening for the first driving gear 62 to mesh with the driving gear ring 51. The fixing ring 63 is used to fix the placement basket 41 and the pulling cover 44, so as to avoid the placement basket 41 from rotating when the driving gear ring 51 rotates, thereby ensuring that the placement opening remains upward.

[0031] The control gear 72 is driven to rotate by the driving motor 71, and the second driving gear 76 is driven to rotate by the control gear 72, so that the second driving gear drives the rotating rod 75 to rotate. At this time, the first driving gear 62 fixed on the rotating rod 75 will rotate with the rotating rod 75 to realize the rotation of the rotating wheel.

[0032] In order to prevent the alkaline solution from dripping onto the driving motor 71 when it is introduced, a waterproof cover 73 is provided to seal the position of the second driving gear 76, thereby ensuring that the solution will not drip while the second driving gear 76 rotates.

[0033] Reference Figures 6-7 The bottom of the decomposition tank 1 is provided with a guide arc plate 9, and the guide arc plate 9 is a semicircular arc plate. The rotating rod 75 is provided with a guide component 8, and the guide component 8 is used to guide the decomposed impurities; The material guiding assembly 8 includes a material guiding spiral blade 81 and a material outlet box 82. The material guiding spiral blade 81 is fixedly mounted on the rotating rod 75 and arranged inside the material guiding arc plate 9. The material outlet box 82 is arranged on a side of the decomposition tank 1 close to the console 3 and is connected to the material guiding plate.

[0034] Since some insoluble impurities are generated during the dissolution process of the alkaline solution, these impurities need to be collected and then further processed. The existing method requires waiting until the decomposition is completed before these impurities can be collected and processed, which reduces the efficiency of the entire hydrolysis; By setting a guide arc plate 9 at the bottom of the elliptical decomposition tank 1, the impurities that cannot be decomposed will fall to the bottom of the decomposition tank 1, and will gradually accumulate inside the guide arc plate 9 due to gravity. The rotating rod 75 is driven to rotate by the rotating second driving gear 76, so that the guide spiral blade 81 is rotated, and the impurities that fall into the guide arc plate 9 are gradually pushed to one side, and finally fall and accumulate in the outlet box 82. The impurities are then transferred and reprocessed through the outlet box 82, which can improve the efficiency of the entire processing and decomposition.

[0035] At the same time, the telescopic rod 74 is used to control the up and down movement of the rotating rod 75. When the decomposition device is not working, the telescopic rod 74 descends, so that the first drive gear 62 is separated from the driving gear ring 51 and no longer meshes, but the meshing degree of the control gear 72 below and the second drive gear 76 is strengthened. When the decomposition device is working, the telescopic rod 74 moves up, so that the first drive gear 62 is separated from the driving gear ring 51 and meshes, while the control gear 72 and the second drive gear 76 are still meshed to ensure normal drive. In order to facilitate the adjustment of the meshing condition, the teeth of the first drive gear 62, the driving gear ring 51, the control gear 72 and the second drive gear 76 are all set to be long strips for easy control.

[0036] The rotating assembly 5 and the material guiding assembly 8 are driven by a driving motor 71 to work simultaneously, thereby optimizing the overall structure, reducing energy consumption and ensuring the decomposition effect.

[0037] Reference Figure 4 and Figure 6 The side of the console 3 close to the placement basket 41 is fixedly connected with an ultrasonic probe 10. The side of the placement basket 41 close to the console 3 is provided with a bayonet, and the ultrasonic probe 10 is clamped inside the bayonet.

[0038] In order to improve the efficiency of decomposition, an ultrasonic probe 10 is provided. Ultrasonic waves generate high-frequency vibrations in the alkaline solution to form tiny bubbles. When the bubbles collapse instantly, local high temperature (about 5000K) and high pressure (about 1000atm) are released to destroy the macromolecular structures of proteins, fats, etc., and promote their rapid reaction with the alkaline solution, which can shorten the hydrolysis time by 30%-50%, and has a significant effect on difficult-to-decompose connective tissues such as fascia and cartilage. At the same time, the ultrasonic cavitation effect can physically penetrate the bacterial and viral envelopes, and combined with the high pH value of the alkaline environment, double inactivation is achieved, with a pathogen killing rate of nearly 100%; Ultrasonic vibration eliminates the stratification between the alkali solution and the corpse, ensuring that the solution fully contacts the interior of the tissue and avoiding local undecomposed residues.

[0039] Reference Figures 6-7 Two water pipes 11 are symmetrically fixedly installed on both sides of the decomposition tank 1, and a plurality of spray heads are fixedly connected to the water pipes 11 at equal intervals. Two mounting frames 12 are fixedly connected to the side of the console 3 close to the placement basket 41. The mounting frames 12 are located above the placement opening of the placement basket 41, and a plurality of spray heads are fixedly connected to the bottom of the mounting frames 12.

[0040] According to different stages of decomposition, different decomposition solutions are introduced into the decomposition tank 1 to ensure rapid decomposition of the corpse. When the solution is less, the solution can be sprayed directly onto the corpse through the multiple nozzles on both sides and the spray head above, thereby improving the decomposition effect.

[0041] A decomposition method using the above-mentioned animal carcass decomposition device, the decomposition steps comprising: S1: placing the body to be decomposed into the placing basket 41, and then transferring the placing basket 41 into the decomposition tank 1 to prepare for decomposition; S2: The first stage: alkaline protease treatment, the activity of alkaline protease is controlled at 37-55℃, pH value is controlled at 8-10, to ensure the highest activity. Alkaline protease is more active in an environment with low ionic strength. Alkaline protease can decompose proteins and make the corpse into smaller peptides and amino acids, which is convenient for subsequent processing; S3: The second stage: treatment with alkaline lipase. Since alkaline lipase can decompose fat and convert it into substances that are more easily utilized by organisms, the temperature is maintained at around 37 - 55 °C at this time when the activity is the highest, and the pH value is controlled within the range of 8 - 11 to ensure the highest activity; S4: The third stage: saponification reaction. Through the saponification reaction, fat reacts with alkali to generate higher fatty acid salts and glycerol. This is an important step in the biological decomposition process. The higher fatty acid salts and glycerol generated by the saponification reaction can improve biodegradability, making the substances after biological decomposition more easily absorbed by the environment; S5: The fourth stage: treatment of the mixture. Through chemical reactions, such as acid-base neutralization and oxidation-reduction, harmful substances in the mixture are converted into harmless substances to reduce environmental pollution; S6: The fifth stage: treatment of the inorganic skeleton. Chemical substances such as strong acids or strong alkalis are used to dissolve or decompose the skeleton to convert it into inorganic substances; S7: During the entire treatment stage, the rotation assembly 5 is controlled to rotate by the driving motor 71, thereby driving the animal carcass placed inside the rotation assembly 5 to rotate, improving the decomposition efficiency. At the same time, the decomposition is accelerated by turning on the ultrasonic probe 10.

[0042] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.

10. A decomposition method using the decomposition device for animal carcasses according to claims 1 to 9, characterized in that: The decomposition steps include: S1: placing the body to be decomposed into a placing basket (41), and then transferring the placing basket (41) into a decomposition tank (1) to prepare for decomposition; S2: The first stage: alkaline protease treatment, the activity of alkaline protease is controlled at 37-55℃, pH value is controlled at 8-10, to ensure the highest activity. Alkaline protease is more active in an environment with low ionic strength. Alkaline protease can decompose proteins and make the corpse into smaller peptides and amino acids, which is convenient for subsequent processing; S3: The second stage: alkaline lipase treatment, alkaline lipase can decompose fat and convert it into substances that are more easily bioavailable. At this time, the temperature is kept at around 37-55℃ for the highest activity, and the pH value is controlled in the range of 8-11 to ensure the highest activity; S4: The third stage: saponification reaction, through which fat and alkali react to produce higher fatty acid salts and glycerol, is an important step in the biodegradation process. The higher fatty acid salts and glycerol produced by saponification can improve biodegradability and make the biodegradable substances more easily absorbed by the environment; S5: The fourth stage: mixture treatment, through chemical reactions, acid-base neutralization, oxidation-reduction, etc., the harmful substances in the mixture are converted into harmless substances to reduce environmental pollution; S6: Stage 5: Inorganic bone treatment, using chemicals such as strong acids or alkalis to dissolve or decompose bones and convert them into inorganic substances; S7: During the entire processing stage, the rotating assembly (5) is controlled to rotate by the driving motor (71), thereby driving the animal carcass placed inside the rotating assembly (5) to rotate, thereby improving the decomposition efficiency, and at the same time, the decomposition is accelerated by turning on the ultrasonic probe (10).
