[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3 In an embodiment of the utility model, a domestic waste fermentation device with real-time temperature control includes an outer shell 1 and an inner shell 16 welded to the inner wall of the outer shell 1. The outer wall of the inner shell 16 and the inner wall of the outer shell 1 are formed with a heat exchange cavity. A heat uniformity mechanism that penetrates to the outside of the outer shell 1 is installed in the heat exchange cavity. The heat uniformity mechanism is used to stir the hot water in the heat exchange cavity. At this time, the heat distribution of the hot water is uniform. A crushing mechanism is installed on the top of the outer shell 1. The crushing mechanism is used to crush large particles in the domestic waste; a stirring motor 13 is installed at one end of the outer shell 1, and the output end of the stirring motor 13 is connected to a stirrer 15. The stirrer 15 is located on the inner periphery of the inner shell 16.

[0020] In this embodiment, microorganisms and domestic waste are added to the pulverizing mechanism, which pulverizes large pieces of waste (such as bones) in the domestic waste. The pulverized waste and microorganisms enter the inner shell 16. At this time, the hot water medium in the heat exchange cavity exchanges heat with the material in the inner shell 16. The hot water medium after heat exchange is discharged and enters new hot water medium. Under the action of the running heat uniformity mechanism, the hot water medium promotes uniform heat distribution of the hot water medium, so that the microorganisms in the inner shell 16 can effectively reproduce at a suitable and stable temperature, thereby promoting the fermentation of domestic waste.

[0021] Please refer to Figure 2 and Figure 3 The crushing mechanism includes a fixed cylinder 2 fixedly connected to the top of the shell 1, and a fixed frame 3 is fixedly installed on the top of the shell 1 at the outer periphery of the fixed cylinder 2. A rotating motor 4 is fixedly installed on the top of the top plate of the fixed frame 3. The output end of the rotating motor 4 passes through the bottom of the top plate of the fixed frame 3, and the output end of the rotating motor 4 is fixedly connected to a crushing cylinder 5. The crushing cylinder 5 is located in the inner cavity of the fixed cylinder 2, and the gap between the outer wall of the crushing cylinder 5 and the inner wall of the fixed cylinder 2 gradually decreases from top to bottom.

[0022] In this embodiment: by starting the rotating motor 4, the rotating motor 4 drives the pulverizing drum 5 to rotate, and then the domestic garbage is poured into the interior of the fixed drum 2. When the pulverizing drum 5 rotates, the domestic garbage enters between the inner periphery of the fixed drum 2 and the outer periphery of the pulverizing drum 5. At this time, the domestic garbage contacts the outer periphery of the pulverizing drum 5 under the action of friction. Under the action of friction, the domestic garbage is crushed and then enters the inner shell 16, reducing the particles of the domestic garbage, which is more conducive to fermentation.

[0023] Please refer to Figure 2 and Figure 3 The heat uniforming mechanism includes two plastic screws 17 rotatably installed in the heat exchange clamp cavity. The outer periphery of the plastic screw 17 is threadedly connected to a heat uniforming plate 18. One end of the two plastic screws 17 passes through the outside of the shell 1, and the plastic screw 17 is rotatably connected to the shell 1. A seal is provided at the rotational connection position of the plastic screw 17 and the shell 1. One end of the two plastic screws 17 is located on the outside of the shell 1 and is equipped with a belt pulley 9. The two belt pulleys 9 are connected by a belt 10. A forward and reverse motor 11 is installed on the outside of one end of the shell 1 through a mounting bracket. The output end of the forward and reverse motor 11 is connected to a belt pulley 9. A water inlet pipe 14 connected to the heat exchange clamp cavity is installed on the top of the shell 1, and a water outlet pipe 12 connected to the heat exchange clamp cavity is installed at the bottom end of the shell 1.

[0024] In this embodiment: Since the length of the inner shell 16 and the outer shell 1 is longer, when the hot water medium is located in the heat exchange clamp cavity, by starting the forward and reverse motor 11, the forward and reverse motor 11 drives the belt pulley 9 connected thereto to rotate, and the belt pulley 9 drives another belt pulley 9 to rotate through a belt, and the two rotating belt pulleys 9 drive the plastic screw 17 connected thereto to rotate. At this time, the uniform heat plate 18 with a porous structure moves back and forth in the heat exchange clamp cavity under the action of its internal thread. At this time, the movement of the uniform heat plate 18 prompts the hot water medium to move in the heat exchange clamp cavity, prompts the hot water medium to flow, and prompts uniform heat distribution, thereby avoiding uneven heat distribution and uneven temperature in the inner shell 16, which leads to uneven fermentation.

[0025] Please refer to Figure 1 and Figure 2 An air inlet pipe 7 for air intake is installed on the top of the shell 1, and an air outlet pipe 8 is installed on one side of the air inlet pipe 7 on the top of the shell 1, and the air outlet pipe 8 is used for exhaust.

[0026] In this embodiment: During the fermentation process, an air pump is connected to the air outlet pipe 8 through a pipeline to discharge the gas (such as hydrogen and carbon dioxide) produced by the fermentation. After the gas is discharged, another air pump is connected to the air inlet pipe 7 through a pipeline to input air to promote the reproduction of microbial aerobic bacteria.

[0027] Please refer to the figure in particular. The upper half of the crushing cylinder 5 is a conical structure. A scraper 6 is fixedly installed on the top plate of the fixed frame 3. The bottom end of the scraper 6 fits into the cylindrical surface of the conical structure of the upper half of the crushing cylinder 5.

[0028] In this embodiment, after dumping domestic garbage, part of the garbage will adhere to the top of the crushing drum 5, and the rotating crushing drum 5 contacts the bottom end of the scraper 6 to scrape off the adhered garbage.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
