[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 8 The present invention provides a technical solution: an ultrasonic-assisted alkaline hydrolysis device for animal tissue, comprising: an equipment box 1 with a self-locking wheel installed at the bottom; an alkaline water reaction tank 2 is fixedly connected to the inside of the equipment box 1, an electric heating plate 15 is embedded and installed on the inner wall of the alkaline water reaction tank 2, an ultrasonic component is provided at the bottom of the alkaline water reaction tank 2, and the ultrasonic component includes an ultrasonic transducer 7 fixedly connected to the bottom of the alkaline water reaction tank 2 for enhancing liquid circulation; a filter screen 3 is placed inside the alkaline water reaction tank 2, a plurality of separation limit grooves 17 are opened on the inner wall of the filter screen 3, and a separation plate 16 is detachably installed in the separation limit groove 17; a sealing cover plate 4 is rotatably placed on one side of the equipment box 1, and a ventilation hood 9 for exhaust or ventilation and a one-way air valve 10 for pressurizing the alkaline water reaction tank 2 are fixedly connected to the top of the sealing cover plate 4.

[0019] It should be noted that a highly alkaline solvent is prepared before the operation of the present invention, and the animal carcasses and / or tissues are immersed in the highly alkaline solvent. The solution is an aqueous solution of sodium hydroxide (NaOH) or potassium hydroxide (KOH), with an HP value of about 13. The concentration of this highly alkaline solvent is an aqueous solution of 1.0 to 2.5 moles, or about 4%-10% (by weight) of sodium hydroxide aqueous solution. The ratio of alkali metal hydroxide to animal tissue weight is 1:10, which ensures that there is enough alkali to complete the dissolution of animal tissue. Or converted to, 40 kg of NaOH dissolved in 900 liters of water is added to 100 kg of dry weight protein, or 40 kg of NaOH dissolved in 500 liters of water is added to 500 kg of fresh or frozen animals (by weight). After the animal remains are immersed in the highly alkaline solvent, in order to maintain the ideal chemical reaction efficiency. The whole process is carried out in a closed alkaline water reaction tank 2, while ensuring that the high alkaline solvent is isolated from the environment; in order to speed up the reaction process, the solution is heated to a temperature of 80-130°C by an electric heating plate 15, and the most ideal temperature range is 100-120°C (under pressure). In addition, a detergent with a concentration not exceeding 1%, such as sodium dodecyl sulfate or sodium deoxycholate, can be added to the high alkaline solvent to increase the dissolution rate; before immersing in the high alkaline solvent, large animal carcasses can be dismembered into small pieces, or small animal carcasses can be divided into two halves, or the abdominal cavity and chest cavity of the intact animal can be opened, so that more animal tissue surface area can be exposed to the high alkaline solvent, thereby shortening the reaction time. In order to shorten the reaction time, an excess of fresh high alkaline solvent can also be continuously provided to the animal carcass and tissue surface. This can be achieved by accelerating the circulation of the high alkaline solvent through an ultrasonic component. After the animal tissue is completely dissolved, the undissolved solid debris that remains mainly includes the inorganic part of the animal bone structure, and other common insoluble parts include rubber, plastic, glass, paper, etc. These fragments can be directly disposed of as ordinary solid waste after being separated from the solution and washed. If bones and teeth are to be dissolved together, about 2% ethylenediaminetetraacetic acid (EDTA) is added to a highly alkaline solvent. The addition of this chelating agent completely dissolves the calcium phosphate salts in bones and teeth. The residual solution contains an alkaline mixture of alkali metal salts, amino acids and peptides, sugar acids, nucleotides, small peptides, fatty acids in lipids, phosphates produced by lipid and nucleic acid decomposition, soluble calcium salts, pigments, sugars, sugar alcohols, hydrocarbons and inorganic substances. These substances are the same as those contained in all commercial and household food waste. The solution contains compounds that are non-toxic and can be biodegraded by bacteria or fungi in soil and sewage treatment systems. Since the solution at the end of the reaction process contains only non-toxic and biodegradable compounds, it needs to be diluted if the HP value is too high.

[0020] like Figure 2As shown, the ultrasonic component further includes an ultrasonic generator 12 fixedly connected to the outside of the equipment box 1 , and the ultrasonic generator 12 is electrically connected to the ultrasonic transducer 7 .

[0021] It should be noted that the acoustic wave transducer of the present invention converts the electrical energy emitted by the ultrasonic generator into mechanical vibrations, and then transmits the vibrations to the treatment medium. The ultrasonic energy can increase the fluidity of the solvent by inducing tiny vibrations between the solvent molecules, thereby making it circulate more effectively on the surface of the tissue or the surface of the animal corpse. The ultrasonic wave can also promote the penetration of the solvent into the deep layer of the tissue, helping to clean or dissolve some substances on the surface and in the tissue. Especially when using a highly alkaline solvent, the ultrasonic wave can not only accelerate the flow of the solvent, but also help increase the chemical reaction rate of the solvent on the surface and tissue.

[0022] like Figure 1 , 7 As shown in , 8, a water inlet pipe 5 and a drain pipe 6 are fixedly connected to the bottom of the alkaline water reaction tank 2, solenoid valves are installed in the middle of the water inlet pipe 5 and the drain pipe 6, and one end of the water inlet pipe 5 and the drain pipe 6 pass through the interior of the equipment box 1, and a filter box 13 is fixedly connected to one end of the drain pipe 6, and a filter square net 14 is detachably installed inside the filter box 13 for filtering undissolved solid matter.

[0023] It should be noted that the water inlet pipe 5 of the present invention is used to inject the decomposition solution into the alkaline water reaction tank 2. The solution is injected into the alkaline water reaction tank 2 through the solenoid valve and the corresponding pump system. When the alkaline water reaction tank 2 is drained, after the animal carcass is completely dissolved, there are usually still remaining solid residues, namely: bone residues, etc. The solution enters the filter box 13 and the filter net 14 through the drain pipe 6. After the drainage is completed, the impurities can be removed from the filter net 14 by disassembling the filter net 14.

[0024] like Figure 3 , 5 As shown, a booster pump 18 is fixedly connected to the outside of the equipment box 1 , and the output end of the booster pump 18 is fixedly connected to the one-way air valve 10 .

[0025] It should be noted that a sealing strip is provided at the bottom of the sealing cover plate 4 of the present invention. When the sealing cover plate 4 contacts the alkaline water reaction tank 2, the alkaline water reaction tank 2 can be sealed. During the solution reaction, the interior can be heated by the electric heating plate 15, and the interior of the alkaline water reaction tank 2 can be pressurized by the booster pump 18, so that the reaction is within the specified temperature and pressure, making the reaction faster.

[0026] like Figure 1 , 3 As shown in FIG. 5 , the top of the equipment box 1 is fixedly connected to the dilution pipe 11 and the pressure gauge, and a ball valve is provided in the middle of the dilution pipe 11.

[0027] It should be noted that a control panel and a display are provided on the outside of the equipment box 1 of the present invention, and a pH sensor is provided inside the alkaline water reaction tank 2. The pH sensor can display the pH value inside the alkaline water reaction tank 2 on the display, and the pressure gauge can detect the pressure inside the alkaline water reaction tank 2. When the pH value inside the alkaline water reaction tank 2 needs to be adjusted, the dilution tube 11 can be connected to the corresponding solution, and the adjusting solution can be injected into the alkaline water reaction tank 2 to adjust the pH value.

[0028] like Figure 1 , 2 As shown in Figures 3, 4 and 5, a rotating shaft 19 is rotatably connected to one side of the equipment box 1, and the rotating shaft 19 is fixedly connected to the sealing cover plate 4 through an L-shaped frame. A reducer 21 is fixedly connected to one side of the equipment box 1, and the output end of the reducer 21 is fixedly connected to the rotating shaft 19, and the input end of the reducer 21 is fixedly connected to the motor 20.

[0029] It should be noted that the reducer 21 of the present invention is a worm gear reducer. Under the premise of its self-locking, the angle of the sealing cover plate 4 can be adjusted arbitrarily. When the angle of the sealing cover plate 4 is adjusted, the motor 20 reaches the rotating shaft 19 through the reducer 21, and the rotating shaft 19 drives the sealing cover plate 4 to rotate through the L-shaped frame, thereby realizing the adjustment of the angle of the sealing cover plate 4 and realizing opening and closing.

[0030] like Figure 1 , 2 As shown in Figure 7, a valve is provided in the middle of the ventilation hood 9, and the interior of the ventilation hood 9 is filled with glass fiber.

[0031] It should be noted that, when the present invention is ventilated, the corresponding valve is opened and the physical structure of the filter material is used to absorb or block the toxic smoke particles.

[0032] like Figure 1 , 2 As shown in FIGS. 3 and 4 , a refrigerator 8 is fixedly connected to one side of the equipment box 1 .

[0033] It should be noted that, in the present invention, when the animal tissue needs to be stored for a period of time before being processed, refrigeration may be required. The refrigerator 8 has a box body and a door, and a refrigeration system is provided in the box body. The refrigeration system includes a compressor, a condenser, an expansion valve and an evaporator. The compressor compresses the gas (usually the refrigerant) into a high-pressure gas; the high-pressure gas enters the condenser, releases heat and becomes liquid; the pressure of the liquid refrigerant drops sharply when passing through the expansion valve, and becomes a low-temperature and low-pressure gas; the low-temperature gas enters the evaporator, absorbs the heat in the refrigerator, lowers the temperature, and finally returns to the compressor for recirculation.
