[0002] The harmless disposal of dead livestock and diseased animals refers to the scientific and safe treatment of livestock and diseased animals that have died from disease or accidents to prevent the spread of disease and environmental pollution. Numerous methods exist, including incineration, deep burial, chemical treatment, and high-temperature and high-pressure treatment. Hydrolysis is a common method, particularly suitable for large-scale disposal of dead livestock and diseased animals.

[0003] Chinese patent publication number CN212525391U discloses a harmless hydrolysis reaction device for the treatment of dead poultry and livestock, comprising two symmetrically arranged shaft frames, a hydrothermal reactor body being arranged between the two shaft frames, a stirring shaft passing through the interior of the hydrothermal reactor body, the outer sides of the stirring shaft being rotatably connected to the two shaft frames respectively, and a shaft seal being installed at the connection between the stirring shaft and the hydrothermal reactor body. In this utility model, the traditional method for treating dead poultry and livestock is changed, and the harmless treatment and resource utilization of dead poultry and livestock are achieved. Through the provided stirring mechanism, when in use, the stirring shaft is rotated to cause the arc-shaped stirring paddle and the propulsion stirring paddle to stir the dead poultry and livestock inside the hydrothermal reactor body, which can improve the efficiency of hydrolysis of dead poultry and livestock. At the same time, the outer walls of the arc-shaped stirring paddle and the propulsion stirring paddle will scrape the inner wall of the hydrothermal reactor body, thereby improving the convenience of subsequent cleaning inside the hydrothermal reactor body.

[0004] However, a certain amount of solid waste is still produced after the hydrolysis reaction of poultry and livestock, which can easily cause blockage of the discharge pipe when discharged, and the device cannot separate the hydrolyzed liquid from the solid waste after hydrolysis. Furthermore, when recovering the amino acids and fatty acids produced by the hydrolysis reaction, a separate filter is required to separate the hydrolyzed liquid from the solid waste, which is relatively inconvenient. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the solid waste in the discharge pipe of the existing livestock and poultry harmless treatment hydrolysis reaction tank is easily blocked when being discharged; and the hydrolyzed liquid after hydrolysis cannot be separated from the solid waste.

[0006] In order to solve the above problems, the technical solution of the utility model is as follows: a hydrolysis reaction tank for harmless treatment of dead poultry and livestock, comprising a tank body, a stirring assembly installed inside the tank body and a heating assembly arranged outside the tank body, wherein the top of the tank body is provided with a feed pipe and the bottom is provided with a discharge pipe;

[0007] The stirring assembly includes a stirring shaft, on which are mounted two first blades and two second blades; a reduction motor for driving the stirring shaft is mounted on the top of the tank body; a fixed shaft extending into the interior of the discharge pipe is fixedly connected to the bottom of the stirring shaft, and a spiral blade is mounted on the fixed shaft;

[0008] A piston is movably installed inside the discharge pipe, and a plurality of liquid discharge ports and a plurality of material discharge ports are opened on the discharge pipe, and a filter screen is installed at the liquid discharge port.

[0009] Furthermore, the heating assembly includes a protective cover installed on the outer side of the lower part of the tank body, and a heating chamber is formed between the protective cover and the tank body. An air inlet pipe and an air outlet pipe are respectively provided on both sides of the heating chamber, and a drain pipe is provided at the bottom.

[0010] Furthermore, the paddle one is an arc-shaped blade adapted to the bottom of the tank body, and is installed on the stirring shaft through a positioning rod one.

[0011] Furthermore, the second blade is a spiral blade and is installed on the stirring shaft through a plurality of positioning rods.

[0012] Furthermore, a plurality of water-permeable holes are provided on the spiral blade.

[0013] Furthermore, a bottom cover is installed at the bottom of the discharge pipe, an electric cylinder is installed on the bottom cover, and the piston is installed at the output end of the electric cylinder.

[0014] Furthermore, the top of the piston is conical, and the height of the liquid discharge port is greater than the height of the material discharge port.

[0015] The advantages of the present invention compared with the existing technology are: the present invention moves the piston through the contraction of the electric cylinder, and when the piston moves below the discharge port, the hydrolyzed liquid produced by hydrolysis can be discharged and collected through the discharge port; the piston moves below the discharge port, and the reduction motor rotates in the opposite direction, and under the action of the spiral blades, the solid waste can be discharged and collected through the discharge port, and the solid waste is discharged by the spiral blades, which can prevent the discharge pipe from being blocked.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1 、 Figure 2 and Figure 4 As shown, a hydrolysis reaction tank for harmless treatment of dead poultry and livestock includes a tank body 1, a stirring assembly installed inside the tank body 1 and a heating assembly arranged on the outside of the tank body 1. A feed pipe 2 is provided on the top of the tank body 1, and a discharge pipe 3 is provided at the bottom. The heating assembly includes a protective cover 10 installed on the outside of the lower part of the tank body 1. A heating chamber is formed between the protective cover 10 and the tank body 1. An air inlet pipe 11 and an air outlet pipe 12 are respectively provided on both sides of the heating chamber, and a liquid discharge pipe 13 is provided at the bottom.

[0024] The heating chamber is connected to an external steam heating system through the air inlet pipe 11 and the air outlet pipe 12, so that the inside of the tank body 1 can be heated; a temperature and pressure sensor can be installed inside the tank body 1 to monitor the temperature and pressure inside the tank body 1.

[0025] like Figure 4 and Figure 5 As shown, the stirring assembly includes a stirring shaft 4, on which are mounted two paddle blades 5 and two paddle blades 6. The paddle blade 5 is an arc-shaped blade adapted to the bottom of the tank body 1 and is mounted on the stirring shaft 4 through a positioning rod 8. The paddle blade 6 is a spiral blade and is mounted on the stirring shaft 4 through a plurality of positioning rods 9. A reduction motor 7 for driving the stirring shaft 4 to rotate is mounted on the top of the tank body 1. A fixed shaft 14 extending to the inside of the discharge pipe 3 is fixedly connected to the bottom of the stirring shaft 4. A spiral blade 15 is mounted on the fixed shaft 14, and a plurality of water-permeable holes are provided on the spiral blade 15.

[0026] When the hydrolysis reaction is being stirred, the reduction motor 7 drives the blade 1 5 and the blade 2 6 to rotate through the stirring shaft 4, so as to achieve stirring of the material inside the tank body 1, so as to facilitate uniform heating of the material; the stirring shaft 4 drives the spiral blade 15 to rotate forward through the fixed shaft 14, so as to transport the material in the discharge pipe 3 to the inside of the tank body 1, thereby preventing the material from accumulating in the discharge pipe 3; when discharging, the reduction motor 7 drives the spiral blade 15 to rotate in the opposite direction through the stirring shaft 4 and the fixed shaft 14, so as to transport the solid waste inside the tank body 1 to the discharge pipe 3, thereby preventing the discharge pipe 3 from being blocked.

[0027] like Figure 3 、 Figure 4 and Figure 5 As shown, a piston 16 is movably installed inside the discharge pipe 3, and a plurality of drainage ports 17 and a plurality of discharge ports 18 are provided on the discharge pipe 3. A filter is installed at the drainage port 17. A bottom cover 19 is installed at the bottom of the discharge pipe 3. An electric cylinder 20 is installed on the bottom cover 19. The piston 16 is installed at the output end of the electric cylinder 20. The top of the piston 16 is conical, and the height of the drainage port 17 is greater than the height of the discharge port 18.

[0028] When it is necessary to add materials for hydrolysis reaction, the electric cylinder 20 extends, so that the position of the piston 16 is raised and higher than the discharge port, which can prevent the liquid from flowing out; when the reaction is completed, the electric cylinder 20 contracts so that the piston 16 moves to below the discharge port 17 and is located above the discharge port 18. At this time, the reduction motor 7 still keeps rotating in the forward direction, and the hydrolyzed liquid produced by hydrolysis can be discharged and collected through the discharge port 17; when the hydrolyzed liquid is discharged, the electric cylinder 20 contracts again so that the piston 16 moves to below the discharge port 18. At this time, the reduction motor 7 rotates in the opposite direction, and the material inside the tank body 1 can be transported to the discharge pipe 3, and then the discharge port 18 discharges and collects the solid waste.

[0029] In specific use, dead poultry and livestock are crushed and added to the interior of the tank body 1 through the feed pipe 2. An appropriate amount of water and medicine are also added to the interior of the tank body 1. The heating chamber is connected to the external steam heating system through the air inlet pipe 11 and the air outlet pipe 12. The reduction motor 7 drives the rotation of the paddle blade 1 5 and the paddle blade 2 6 to achieve stirring of the material inside the tank body 1, facilitating the hydrolysis reaction of the material. The electric cylinder 20 contracts, causing the piston 16 to move below the drain port 17. The hydrolyzed liquid produced by the hydrolysis can be discharged and collected through the drain port 17. The electric cylinder 20 contracts again, causing the piston 16 to move below the discharge port 18. At this time, the reduction motor 7 rotates in the opposite direction, and the material inside the tank body 1 can be transported to the discharge pipe 3. The solid waste is then discharged and collected through the discharge port 18. The solid waste is discharged through the spiral blade 15 to prevent the discharge pipe 3 from clogging.
