Description

Technical Field

[0001] The present invention relates to the technical field of reaction preparation devices, and particularly to a power supply device for a natural gas hydrate energy conversion ship. Background Art

[0002] Natural gas hydrate is an ice-like cage-shaped crystalline compound formed by natural gas and water under high pressure and low temperature conditions. Because of its ice-like appearance and ability to burn when encountering fire, it is called "flammable ice". It is distributed in deep sea or permafrost on land. After combustion, it can generate a large amount of methane gas, and only a small amount of carbon dioxide and water are generated. The pollution is much less than that of coal, oil, etc., and the reserves are huge. Therefore, in the aspect of ship energy supply, the utilization of flammable ice is one of the very promising directions;

[0003] The decomposition and utilization of flammable ice usually occur inside a reaction device. Providing a low-pressure and normal-temperature environment in the reaction device can achieve the dissolution of flammable ice. Currently, in the ship energy supply system, the thermal energy source that can provide for the dissolution of flammable ice is mostly the waste heat of the ship engine. At the same time, a large amount of water resources will be generated during the melting of flammable ice. Therefore, the following problems will exist in the energy conversion process of flammable ice:

[0004] First, the thermal energy resources that the ship engine can provide are limited. During the continuous melting process of a large amount of flammable ice, the generated water bodies are generally at a low temperature. These low-temperature water bodies will further absorb thermal energy, resulting in a low thermal energy absorption rate of the actual flammable ice. Therefore, the actual melting speed and energy conversion rate are slow, and there will be a situation of waste of thermal resources;

[0005] Second, even if the water resources after dissolution are quickly collected on the basis of Problem 1 to prevent the low-temperature water from absorbing heat, the shape of flammable ice is irregular, and there will be a large number of melting pits on the surface of the flammable ice piled up in the reaction device. These surface melting pits will further converge the low-temperature water, resulting in many energy utilization problems in the actual decomposition process of flammable ice.

[0006] Therefore, how to provide a power supply device for a natural gas hydrate energy conversion ship is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] An object of the present invention is to provide a power supply device for a natural gas hydrate energy conversion ship. The present invention can utilize low-temperature water to provide a secondary dissolution operation for flammable ice, and at the same time can effectively remove the low-temperature water converged in the pits on the surface of flammable ice, improving the thermal energy utilization efficiency.

[0008] A power supply device for a natural gas hydrate energy conversion ship according to an embodiment of the present invention includes a reaction component. An inlet component is arranged above the reaction component. The inlet component includes a spiral feed pipe and a material chamber. The spiral feed pipe is rotatably arranged in the material chamber through a transmission motor on one side. The bottom opening of the material chamber is located above a notch partition plate. The notch partition plate is fixed in the reaction component. One end of the spiral feed pipe away from the transmission motor is drivingly connected to a spline main shaft. A turntable component is arranged above the notch partition plate. A melting cage is arranged below the notch partition plate and close to the inside of the reaction component. The spline main shaft sequentially penetrates through the turntable component, the notch partition plate and the melting cage. The axis of the notch partition plate does not contact the spline main shaft. The melting cage is arranged on the surface of the spline main shaft;

[0009] A suspension mechanism is arranged below the notch partition plate. The suspension mechanism includes a motor, a lifting frame and a slip ring rod. The motor is fixed at the bottom of the notch partition plate. The motor drives the lifting frame to move up and down below the notch partition plate. The slip ring rod is rotatably connected to the lifting frame. The slip ring rod is fixed above the melting cage.

[0010] Further, the reaction component includes a kettle body, a liquid extraction pipe and two groups of air inlet and outlet pipes. The two ends of the liquid extraction pipe are respectively communicated above and below the kettle body. The notch partition plate and the turntable component are located between the two communication positions of the two ends of the liquid extraction pipe. A water pump is also connected to the middle position of the liquid extraction pipe. The two groups of air inlet and outlet pipes are respectively fixed on both sides of the kettle body, and a heat pipe is communicated between the two groups of air inlet and outlet pipes.

[0011] Further, the reaction component further includes a water outlet pipe and a collection pipe. The water outlet pipe is communicated with the upper position inside the kettle body close to the turntable component. The collection pipe is respectively communicated with the upper and lower sides of the kettle body close to the turntable component.

[0012] Further, a one-way transmission mechanism is arranged on one side of the spiral feed pipe away from the transmission motor. The one-way transmission mechanism includes a meshing tooth group and a transmission component. The meshing tooth group is drivingly connected to the transmission component through a bevel gear group. The transmission component drives the spline main shaft to rotate inside the kettle body through a toothed belt component.

[0013] Further, the transmission component further includes a first ratchet wheel and a second ratchet wheel. The first ratchet wheel and the second ratchet wheel are engaged with each other. The first ratchet wheel is fixed above the bevel gear group. The axis of the second ratchet wheel is fixed to a pulley at one end of the toothed belt component through a connecting shaft.

[0014] Further, the connecting shaft movably penetrates through a force-bearing slider above. The force-bearing slider slides in a transverse slide rail opened inside the mounting frame. A return spring is further arranged between the force-bearing slider and the inner wall of the transverse slide rail. Anti-slip pressure wheels are arranged on both sides of the mounting frame. The two groups of anti-slip pressure wheels elastically abut against both sides of the toothed belt on the surface of the toothed belt component.

[0015] Furthermore, the turntable assembly includes a semi-circular partition board, two sets of screen plates, and a shaft bump. The semi-circular partition board is fixed to the bottom on one side of the shaft bump, and the two sets of screen plates are respectively fixed at both ends of the semi-circular partition board. The through hole at the axis of the shaft bump is in transmission connection with the spline main shaft through a key groove.

[0016] Furthermore, a pressing mechanism is arranged above the shaft bump. The pressing mechanism includes an electric cylinder, a lever member, and a pressing disc. The bottom of the pressing disc is rotationally connected to the convex rail on the top of the shaft bump through a ball, and the top of the pressing disc is fixed to the sliding shaft through a connecting plate.

[0017] Furthermore, sliding grooves are formed on both sides of the lever member, and a hinge hole is also formed at the position of the sliding groove on one side close to the lever member. The lever member is rotationally connected to the kettle body through the hinge hole. The sliding shaft slides in the single-side sliding groove of the lever member, the electric cylinder is fixed on the surface of the kettle body, and the output end of the electric cylinder slides in the sliding groove on the other side of the lever member through a pressing rod.

[0018] Furthermore, four sets of limiting sliding columns are fixed to the bottom of the notch partition board. The lifting frame slides up and down on the surface of the limiting sliding columns. The output shaft of the motor is fixedly connected to two winding rollers, and two tension belts are wound around the surface of the winding rollers. A steering wheel is arranged at the vertical position of the connecting pin at the bottom of the notch partition board, and one end of the tension belt bypasses the steering wheel and is fixed to the connecting pin on the surface of the lifting frame.

[0019] The beneficial effects of the present invention are as follows:

[0020] By arranging the notch partition board and the turntable assembly, the internal space of the kettle body is partitioned. A large amount of combustible ice can be piled into the melting cage under the notch partition board. The heat pipe is provided with the waste heat of the engine through the air inlet and outlet pipes to carry out the normal dissolution process. The melted low-temperature water converges at the bottom of the kettle body. Compared with the combustible ice, this kind of just-melted low-temperature water can still assist in the melting of the combustible ice. Therefore, the liquid extraction pipe can pump the water body to the upper part of the notch partition board under the action of an external water pump, so as to carry out the primary dissolution operation on the combustible ice that has not started to dissolve above the notch partition board. Compared with the traditional decomposition reaction device, the present invention can effectively utilize heat energy, and at the same time prevent the low-temperature water from further absorbing the heat generated by the heat pipe under the notch partition board, thereby improving the dissolution rate of the combustible ice.

[0021] Through the pressure application mechanism provided in the present invention, after the electric cylinder is started, it can press down or lift up the lever member through the pressure rod. The lever member rotates with the hinge hole as the rotation center, so that the other end of the lever member pulls the connecting plate and the pressing plate to rise or fall through the sliding shaft. At this time, the pressing plate can press or release the shaft convex block below, so that the semi-circular partition plate can be closely attached to or released from the notch partition plate. When in the attached state, the low-temperature water provided by the liquid extraction pipe above the notch partition plate can be normally gathered to soak the combustible ice. On the contrary, after releasing, the rotation of the spline main shaft can normally drive the semi-circular partition plate to rotate, so that the other side of the shaft convex block rotates to the opening of the notch partition plate. At this time, under the push of the sieve plate, the combustible ice above the notch partition plate can normally fall into the melting cage below the notch partition plate for secondary melting operation. At the same time, both ends of the collecting pipe are connected to the upper and lower sides of the notch partition plate to collect the decomposed methane, and the water outlet pipe can normally perform the extraction and collection operation of the low-temperature water;

[0022] Through the one-way transmission mechanism provided in the present invention, after being driven by the transmission motor, it can normally drive the spiral feeding pipe to rotate in the material chamber to realize the continuous feeding of the combustible ice. The spiral feeding pipe can drive the first ratchet wheel to rotate through the meshing tooth group and the bevel gear group. Although the first ratchet wheel meshes with the second ratchet wheel, the rotation directions are opposite, so that the second ratchet wheel drives the force-bearing slider to push a short distance inside the horizontal slide rail. At this time, the spline main shaft does not rotate, so as to realize the normal feeding operation. When the material chamber rotates in reverse, the first ratchet wheel and the second ratchet wheel bite with each other, and the rotation effect directly drives the toothed belt assembly to operate through the connecting shaft. One end of the toothed belt assembly is connected to the spline main shaft, so that the spline main shaft rotates at this time to drive the semi-circular partition plate to rotate for the secondary feeding and dissolving operation. The overall operability is strong and can meet the actual dissolving requirements;

[0023] Through the lifting mechanism provided in the present invention, since the heat pipe is inserted into the melting cage to thermally melt the combustible ice, when it is necessary to remove the low-temperature water in the pits on the surface of the combustible ice in the melting cage, first, through the driving motor, the motor drives the winding roller to rotate while realizing the retraction and release of the tension belt. The tension belt is directly connected to the lifting frame through the connecting pin. Under the action of the gravity of the lifting frame and the retraction and release of the tension belt, the lifting frame moves downward, so that the sliding ring rod also moves downward under the action of the gravity of the melting cage until the melting cage is completely separated from the heat pipe. At this time, if the spline main shaft is driven to rotate, the rotation effect will directly drive the melting cage to rotate, so that the combustible ice inside the melting cage is disintegrated under the action of centrifugal force, and at the same time, the low-temperature water in the pits on the surface is discharged, thereby preventing the low-temperature water from affecting the subsequent thermal decomposition operation.

[0036] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0037] Reference Figures 1 - 8 , including a reaction component 1, a feeding component 2 is arranged above the reaction component 1. The feeding component 2 includes a spiral feeding pipe 22 and a material chamber 23. The spiral feeding pipe 22 is rotatably arranged in the material chamber 23 through a transmission motor 21 on one side. The bottom opening of the material chamber 23 is located above a notch partition plate 3. The notch partition plate 3 is fixed in the reaction component 1. One end of the spiral feeding pipe 22 away from the transmission motor 21 is drivingly connected to a spline main shaft 86. A turntable component 4 is arranged above the notch partition plate 3. A melting cage 6 is arranged inside the reaction component 1 near the lower part of the notch partition plate 3. The spline main shaft 86 sequentially penetrates through the turntable component 4, the notch partition plate 3 and the melting cage 6. The axis of the notch partition plate 3 is not in contact with the spline main shaft 86. The melting cage 6 is arranged on the surface of the spline main shaft 86;

[0038] A suspension mechanism 7 is arranged below the notch partition plate 3. The suspension mechanism 7 includes a motor 71, a lifting frame 74 and a slip ring rod 77. The motor 71 is fixed at the bottom of the notch partition plate 3. The motor 71 drives the lifting frame 74 to move up and down below the notch partition plate 3. The slip ring rod 77 is rotatably connected to the lifting frame 74. The slip ring rod 77 is fixed above the melting cage 6.

[0039] In this implementation, after the driving motor 21 starts, it can normally drive the spiral feeding pipe 22 to rotate inside the material chamber 23. By feeding combustible ice into the material chamber 23, under the driving effect, the combustible ice falls above the notch partition plate 3 or the turntable assembly 4 on the other side of the material chamber 23, that is, inside the reaction assembly 1, and the first natural melting process occurs here. One end of the spiral feeding pipe 22 is also drivingly connected to a one-way driving mechanism 8. The one-way driving mechanism 8 can achieve one-way driving, that is, during the normal feeding process of the spiral feeding pipe 22, the one-way driving mechanism 8 will not drive the spline main shaft 86 to rotate, and the turntable assembly 4 and the melting cage 6 are in a stopped state. After the spiral feeding pipe 22 rotates in reverse, at this time, the driving effect drives the turntable assembly 4 and the melting cage 6 to rotate through the spline main shaft 86 to realize discharging and other operations. The melting cage 6 and the combustible ice inside the melting cage 6 can be normally suspended by the suspension mechanism 7 below the notch partition plate 3, so that they are in full contact with the heat pipe 9 to realize the heat treatment operation. When the motor 71 drives the lifting frame 74 to move downward below the notch partition plate 3, the slip ring rod 77 will also drive the melting cage 6 to move downward on the surface of the spline main shaft 86, while the position of the heat pipe 9 remains unchanged, so that the melting cage 6 is separated from the heat pipe 9, and the melting cage 6 can rotate with the spline main shaft 86 to realize the centrifugal drainage operation.

[0040] Reference Figure 2 and Figure 3 The reaction assembly 1 includes a kettle body 11, a liquid extraction pipe 12 and two groups of air inlet and outlet pipes 13. The two ends of the liquid extraction pipe 12 are respectively communicated above and below the kettle body 11. The notch partition plate 3 and the turntable assembly 4 are located between the two communication positions at the two ends of the liquid extraction pipe 12. A water pump is also connected to the middle position of the liquid extraction pipe 12. The two groups of air inlet and outlet pipes 13 are respectively fixed on both sides of the kettle body 11, and the heat pipe 9 is communicated between the two groups of air inlet and outlet pipes 13. The reaction assembly 1 further includes a water outlet pipe 14 and a collection pipe 15. The water outlet pipe 14 is communicated with the position above the turntable assembly 4 inside the kettle body 11, and the collection pipe 15 is respectively communicated with the upper and lower sides of the kettle body 11 close to the turntable assembly 4.

[0041] In this implementation, the liquid extraction pipe 12 pumps the low-temperature water at the bottom of the inner surface of the kettle body 11 to the upper area of the notch partition plate 3 inside the kettle body 11 through an external water pump to soak the combustible ice. Since the just-melted low-temperature water still has a certain residual temperature, the first decomposition operation of the combustible ice is realized. After decomposing for a period of time, at this time, the water outlet pipe 14 can normally suck the excess low-temperature water above the notch partition plate 3. At the same time, the two connecting pipes of the collection pipe 15 are respectively connected to the upper and lower areas of the notch partition plate 3, so that the methane generated during the decomposition process can be normally sucked through the collection pipe 15 to the next processing unit for purification operation. The two groups of air inlet and outlet pipes 13 are respectively connected to the left and right sides of the kettle body 11, and the heat pipe 9 is communicated between them. In this way, the air inlet and outlet pipes 13 can transfer heat between the heat pipe 9 and the combustible ice by introducing the waste heat gas of the engine into the heat pipe 9.

[0042] refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 A one-way transmission mechanism 8 is arranged on the side of the spiral feed pipe 22 away from the transmission motor 21. The one-way transmission mechanism 8 includes a meshing gear set 81 and a transmission assembly 83. The meshing gear set 81 is connected to the transmission assembly 83 through a bevel gear set 82. The transmission assembly 83 drives the spline main shaft 86 to rotate inside the kettle body 11 through a toothed belt assembly 85. The transmission assembly 83 also includes a first ratchet 831 and a second ratchet 832. The first ratchet 831 and the second ratchet 832 are engaged with each other. The first ratchet 831 is fixed to the top of the bevel gear set 82. The axis of the second ratchet 832 is fixed to the pulley at one end of the toothed belt assembly 85 through the connecting shaft 833. A force-bearing slider 834 is movable through the top of the connecting shaft 833, and the force-bearing slider 834 slides in a transverse slide rail 836 opened inside the mounting frame 835. A return spring 837 is also arranged between the force-bearing slider 834 and the inner wall of the transverse slide rail 836. Anti-skid pressure wheels 84 are arranged on both sides of the mounting frame 835. The two sets of anti-skid pressure wheels 84 elastically resist the two sides of the toothed belt on the surface of the toothed belt assembly 85.

[0043] In the present embodiment, during the process of the spiral feed pipe 22 rotating to realize the feeding of combustible ice, the spiral feed pipe 22 drives the meshing tooth group 81 to operate. The meshing tooth group 81 is composed of a plurality of mutually meshing gears and is movably connected to the inside of the kettle body 11 through a bracket. The bevel gear group 82 above it directly drives the No. 1 ratchet 831 to rotate. The No. 1 ratchet 831 and the No. 2 ratchet 832 mesh with each other. During the rotation process, the No. 1 ratchet 831 continuously drives the No. 2 ratchet 832, and the No. 2 ratchet 832 is pushed by the meshing and will drive the force-bearing slider 834 to move to one side inside the transverse slide rail 836 through the connecting shaft 833, and at the same time squeeze the reset spring 837, so that the connecting shaft 833 will not rotate, and the toothed belt assembly 85 naturally cannot rotate to drive the spline main shaft 86 to rotate. At the same time, the gear The position change of the belt assembly 85 will cause the toothed belt on its surface to loosen. In order to prevent the toothed belt from detaching from the toothed belt assembly 85, anti-skid pressure wheels 84 are arranged on both sides of the mounting frame 835. The anti-skid pressure wheels 84 resist the toothed belt of the toothed belt assembly 85 under the action of elasticity, thereby improving the use effect. Conversely, during the reversal of the spiral feed tube 22, the bite effect of the No. 1 ratchet 831 and the No. 2 ratchet 832 will drive the No. 2 ratchet 832 to rotate, and the rotation effect directly drives the single-side pulley of the toothed belt assembly 85 to rotate through the connecting shaft 833, so that the other side of the toothed belt assembly 85 drives the spline main shaft 86 to rotate, and the spline connection effect of the spline main shaft 86 with the turntable assembly 4 and the melting net cage 6 can drive the turntable assembly 4 and the melting net cage 6 to rotate, thereby realizing centrifugal drainage and secondary unloading operations.

[0044] refer to Figure 4 , Figure 5 andFigure 7 The turntable assembly 4 includes a semicircular partition 41, two sets of screen plates 42 and a shaft protrusion 43. The semicircular partition 41 is fixed to the bottom of one side of the shaft protrusion 43. The two sets of screen plates 42 are respectively fixed to the two ends of the semicircular partition 41. The through hole of the axis of the shaft protrusion 43 is connected to the spline main shaft 86 through a keyway transmission. A pressure mechanism 5 is arranged above the shaft protrusion 43. The pressure mechanism 5 includes an electric cylinder 51, a lever member 53 and a pressing plate 57. The bottom of the pressing plate 57 is rotatably connected to the convex rail at the top of the shaft protrusion 43 through a ball bearing, and the top of the pressing plate 57 is fixed to the sliding shaft 56 through a connecting plate 55. Slide grooves are provided on both sides of the lever member 53, and a hinge hole 54 is further provided at the slide groove position close to one side of the lever member 53. The lever member 53 is rotatably connected to the kettle body 11 through the hinge hole 54, and the sliding shaft 56 slides in the slide groove on one side of the lever member 53. The electric cylinder 51 is fixed on the surface of the kettle body 11, and the output end of the electric cylinder 51 slides in the slide groove on the other side of the lever member 53 through the pressure rod 52.

[0045] In this embodiment, when the electric cylinder 51 is started to drive the pressure rod 52 to move downward, the two ends of the pressure rod 52 will slide in the slide groove on one side of the lever member 53, and the lever member 53 as a whole will rotate on the surface of the kettle body 11 with the hinge hole 54 as the center of the circle, and the other side of the lever member 53 will lift the sliding shaft 56 through the slide groove, and the sliding shaft 56 is connected to the pressing plate 57 through the connecting plate 55. In this way, the pressing plate 57 moves upward, releasing the resistance to the shaft protrusion 43, and the shaft protrusion 43 loses the resistance force, so that the semicircular partition 41 and the notched partition plate 3 are loosened. At this time, the spline main shaft 86 can rotate to normally drive the semicircular partition 41 Rotate so that the semicircular partition 41 rotates to the specified position, opening the gap of the notch partition plate 3. At the same time, under the push of the leakage screen plate 42, the combustible ice falls through the gap of the notch partition plate 3 into the melting net cage 6 below to realize subsequent decomposition work. On the contrary, the electric cylinder 51 rises, and the connecting plate 55 provides a certain downward pressure on the pressing plate 57, so that the shaft protrusion 43 and the semicircular partition 41 can resist the top of the notch partition plate 3. The resistance effect can improve the sealing effect and prevent low-temperature water from penetrating to the bottom of the notch partition plate 3. In this way, the combustible ice above the notch partition plate 3 can be immersed and decomposed.

[0046] refer to Figure 7 and Figure 8 Four groups of limiting slide columns 76 are fixed at the bottom of the notch partition plate 3, and the lifting frame 74 slides up and down on the surface of the limiting slide columns 76. The output shaft of the motor 71 is fixedly connected to two groups of winding rollers 72, and two groups of tension belts 73 are wound around the surface of the winding rollers 72. A steering wheel is set at the vertical position of the connecting pin 75 at the bottom of the notch partition plate 3, and one end of the tension belt 73 passes around the steering wheel and is fixed to the connecting pin 75 on the surface of the lifting frame 74.

[0047] In this implementation scheme, after the motor 71 starts under the notch partition plate 3, it can directly drive the two groups of winding rollers 72 to rotate. The surfaces of the winding rollers 72 are wound with two groups of tension belts 73, and the two groups of tension belts 73 are respectively connected to the two groups of connecting pins 75. Under the guidance of the steering wheel, when the winding rollers 72 wind up, they can drive the lifting frame 74 to rise. The slip ring rod 77 is rotatably buckled inside the lifting frame 74, and the slip ring rod 77 is fixedly connected to the melting cage 6, so that the melting cage 6 slides upward on the surface of the spline main shaft 86 under the rising effect. On the contrary, it will descend under the action of gravity. In this way, the melting cage 6 can effectively realize the separation of the internal combustible ice from the heat pipe 9. Then, by driving the spline main shaft 86 to rotate, the swinging operation of the melting cage 6 can be realized. At this time, the low-temperature water accumulated in the pits on the surface of the combustible ice will be thrown out, and the combustible ice will also be broken under the action of centrifugal force, which helps the subsequent further decomposition work and prevents the problem of low heat utilization rate caused by the further absorption of heat by the low-temperature water.

[0048] Working principle: First, the top of the material chamber 23 is connected to the feed hopper. After the drive motor 21 is started, it drives the spiral feed pipe 22 to rotate inside the material chamber 23, realizing the feeding of combustible ice to the area above the notch partition plate 3 inside the kettle body 11. At the same time, the spiral feed pipe 22 directly drives the first ratchet 831 to rotate through the meshing tooth group 81 and the bevel gear group 82. The second ratchet 832 is stressed and drives the stressed slider 834 to move inside the transverse slide rail 836 through the connecting shaft 833 and compress the return spring 837. The anti-slip pressure wheels 84 on both sides of the mounting frame 835 elastically resist the toothed belt of the toothed belt assembly 85 to prevent it from falling off. After the combustible ice is sufficient, the drive motor 21 is driven in reverse. At this time, the first ratchet 831 engages with the second ratchet 832. The second ratchet 832 rotates and drives the pulley on one side of the toothed belt assembly 85 to rotate, and the pulley on the other side of the toothed belt assembly 85 rotates to drive the spline main shaft 86 to rotate inside the kettle body 11. The spline main shaft 86 is spline-connected to the shaft convex block 43 at the top of the notch partition plate 3. The shaft convex block 43 rotates to drive the semi-circular partition plate 41 and the screen plate 42 to rotate synchronously. The screen plate 42 pushes the combustible ice to the notch of the notch partition plate 3, and the combustible ice falls into the melting cage 6 below the notch partition plate 3. Subsequently, the intake and exhaust pipe 13 supplies heat energy into the heat pipe 9. The heat decomposes the combustible ice in the melting cage 6 into water and methane. The methane gas is pumped and collected through the collection pipe 15, and the water filters through the surface of the melting cage 6 and converges at the bottom of the inner surface of the kettle body 11. After decomposition for a period of time, the motor 71 is started to drive the winding roller 72 to rotate and release the tension belt 73. The tension belt 73 is connected to the lifting frame 74 through the connecting pin 75, and the lifting frame 74 is rotatably connected to the slip ring rod 77, and the slip ring rod 77 is fixed to the melting cage 6. After the tension belt 73 is released, the lifting frame 74 will slide stably downward on the surface of the limit slide post 76 until the melting cage 6 is completely separated from the heat pipe 9. Then the spline main shaft 86 is rotated again, and the melting cage 6 rotates at this time to cause the internal combustible ice to disintegrate, and at the same time, the drainage of the residual low-temperature water is realized. Then the melting cage 6 is reset and docked with the heat pipe 9. At this time, the water pump connected to the liquid extraction pipe 12 works to pump the low-temperature water inside the kettle body 11. The low-temperature water is pumped to the area above the notch partition plate 3. At the same time, the electric cylinder 51 is started to pull up the pressure rod 52. The pressure rod 52 provides an upward pulling force on one side of the lever member 53. The lever member 53 rotates around the hinge hole 54, causing the other side of the lever member 53 to press down the sliding shaft 56. The sliding shaft 56 is fixed to the pressing disk 57 through the connecting plate 55. The pressing disk 57 provides a downward pressure on the top of the shaft convex block 43, so that the semi-circular partition plate 41 and the semi-circular partition plate 41 can better fit the surface of the notch partition plate 3 to prevent the leakage of low-temperature water. The spiral feed pipe 22 rotates again to realize the supply of combustible ice. The combustible ice contacts the low-temperature water at the top of the notch partition plate 3 and absorbs the remaining temperature in the low-temperature water to realize the natural decomposition operation. The decomposed methane is synchronously pumped by the collection pipe 15. Finally, the water outlet pipe 14 pumps the excess low-temperature water at the top of the notch partition plate 3 to realize the complete working process.
