[0042] Before the garbage anaerobic fermentation device starts working, the garbage raw materials are first put into the distribution pipe 218, and then the distribution pipe 218 is in a closed structure through the movable clamping of the clamping rod 203 and the clamping hole 102, and then the mixing work is started.

[0043] For example, Figure 8As shown, the stirring mechanism 206 includes a disc body 2061, a filling cushion layer 207 is sleeved on the outer wall of the disc body 2061, a plurality of sliding cavities 2063 are provided in a circular array at the bottom of the disc body 2061, a group of threaded rods 2062 are arranged in each group of the sliding cavities 2063, and each group of the threaded rods 2062 are rotatably connected in the sliding cavity 2063, and a plurality of third motors 2067 are distributed in a circular array on the inner wall of the disc body 2061, and the output end of each group of the third motors 2067 is transmission-connected to one of the groups of the threaded rods 2062, and a group of sliding blocks 2064 are threadedly connected to each group of the threaded rods 2062, and each group of the sliding blocks 2064 are slidably connected in the sliding cavity 2063, and a group of second motors 2065 are installed at the bottom of each group of the sliding blocks 2064, and a group of stirring rods 2066 are transmission-connected to the output end of each group of the second motors 2065;

[0045] The first electric push rod 204 is started to drive the stirring mechanism 206 to descend, and then the first motor 205 is started to drive the disc body 2061 to rotate, and then drive several groups of stirring rod bodies 20661 to stir. In order to improve the stirring effect, the stirring rod body 20661 is driven to rotate by the second motor 2065 to improve its mixing effect. Then the third motor 2067 is started, and the third motor 2067 drives the threaded rod 2062 to rotate. The threaded rod 2062 drives the sliding block 2064 to slide in the sliding cavity 2063, and then drives several groups of stirring rod bodies 20661 to stir back and forth. During the stirring process, heat can be dissipated through the constant temperature block 20665 to balance its internal temperature, thereby improving the solid-liquid mixing effect of the garbage raw materials.

[0046] For example, Figure 5As shown, a third electric push rod 208 is installed at the bottom center of the disc body 2061, and an extrusion disc 209 is installed on the output end of the third electric push rod 208. The top of the extrusion disc 209 is provided with a plurality of groups of sliding cavities 224 in an annular array. The outer wall of each group of the stirring rod body 20661 is slidably attached to the inner wall of the sliding cavity 224. A group of first connecting pipes 212 are connected between each group of the sliding cavities 224. The top of the extrusion disc 209 is provided with a plurality of groups of water inlet cavities 210 in an annular array. A group of first gauze layers 211 are arranged in each group of the water inlet chamber 210, the top of the extrusion disc 209 is connected to a second connecting pipe 213, the other end of the second connecting pipe 213 passes through a distribution pipe 218 and is connected to a vacuum box 214, the vacuum box 214 is installed on the outer wall of the distribution pipe 218, a first vacuum pump 215 is installed on the outer wall of the vacuum box 214, the outer wall of the vacuum box 214 is connected to a third connecting pipe 216, and the outer wall of the third connecting pipe 216 is installed with a second vacuum pump 217.

[0047] For example, Figure 6 As shown, a diverter ring 219 is sleeved on the outer wall of the diverter ring 219, and a plurality of groups of first electric ball valves 221 are distributed in a circular array on the inner wall of the diverter ring 219, and the other end of each group of the first electric ball valves 221 is connected to the outer wall of the diverter pipe 218, and a group of second gauze layers 220 are arranged at the junction of each group of the first electric ball valves 221 and the diverter pipe 218, a third vacuum pump 222 is installed on the outer wall of the diverter ring 219, and a fourth connecting pipe 223 is connected to the bottom of the diverter ring 219.

[0048] When the solid and liquid are mixed to form slurry, the first electric ball valve 221 is opened to allow the slurry liquid to flow into the diverter ring 219. In this process, the slurry is driven by the second gauze layer 220 to separate the solid and liquid. Then the third electric push rod 208 is started, and the third electric push rod 208 drives the extrusion disc 209 to descend. Then the slurry is squeezed by the extrusion disc 209 to squeeze the liquid in the slurry into the diverter ring 219. When the liquid flows into the top of the extrusion disc 209 through the sliding cavity 224, it flows into the extrusion disc 209 through the water inlet cavity 210. The first vacuum pump 215 is started to drive the second connecting pipe 213 to suck the liquid remaining in the extrusion disc 209 into the vacuum box 214.

[0049] For example, Figure 7As shown, the fermentation component 3 includes a first fermentation box 301, the other end of the third connecting pipe 216 penetrates the outer shell body 101 and is connected to the first fermentation box 301, the other end of the fourth connecting pipe 223 penetrates the outer shell body 101 and is connected to the first fermentation box 301, a second electric ball valve 302 is installed at the junction of the fourth connecting pipe 223 and the first fermentation box 301, a first temperature display 303 is installed on the outer wall of the first fermentation box 301, a second fermentation box 304 is arranged at the bottom center of the outer shell body 101, a third electric ball valve 305 is installed on the top of the second fermentation box 304, the other end of the third electric ball valve 305 penetrates the outer shell body 101 and is connected to the bottom of the feed pipe 218, two groups of fourth electric ball valves 306 are symmetrically arranged on the two side walls of the second fermentation box 304, the other end of each group of the fourth electric ball valves 306 is connected to the first fermentation box 301, and a temperature control mechanism 307 is installed on the outer wall of the first fermentation box 301.

[0050] When the solid-liquid separation is in place, the third electric ball valve 305 is opened, and the separated solid slurry is sent into the second fermentation box 304 through the extrusion disc 209, and then the second electric ball valve 302 is opened to allow the liquid slurry in the fourth connecting pipe 223 to flow into the first fermentation box 301, and then the second vacuum pump 217 is started to suck the liquid remaining in the vacuum box 214 into the first fermentation box 301 through the third connecting pipe 216, and then the fourth electric ball valve 306 is opened to make it in a solid-liquid separation state and a connected state at the same time. When the pressure in the second fermentation box 304 is too high, the liquid in the first fermentation box can also play a role in pressure relief, making the work safer.

[0051] For example, Fig. 9 As shown, the temperature control mechanism 307 includes a fixed box 3071, a fifth electric ball valve 3077 is installed at the junction of the fixed box 3071 and the first fermentation box 301, a second temperature display 3072 is installed on the side wall of the fixed box 3071 away from the fifth electric ball valve 3077, a fourth electric push rod 3073 is installed on the inner wall of the bottom of the fixed box 3071, a push plate 3074 is installed on the output end of the fourth electric push rod 3073, a second piston ring 3075 is sleeved on the outer wall of the push plate 3074, the outer wall of the second piston ring 3075 is slidably fitted on the inner wall of the fixed box 3071, a heating block 3076 is installed on the inner wall of the fixed box 3071 close to the second temperature display 3072, a condensation box 3078 is connected to the top of the fixed box 3071, and a sixth electric ball valve 3079 is installed at the junction of the condensation box 3078 and the fixed box 3071.

[0052] During the fermentation process, the temperature is detected through the first temperature display 303. When the fermentation temperature is too low, the heating block 3076 is started to provide heat. In order to speed up the heating speed, the fourth electric push rod 3073 is started to drive the push plate 3074 to rise, so that the internal pressure increases. When it rises to a specified value, the fifth electric ball valve 3077 is opened to assist in raising the temperature in the fermentation box. When the fermentation temperature is high, the cold air released from the condensation box 3078 is neutralized to make the temperature in the fermentation box at an appropriate level, thereby improving the fermentation effect.

[0053] Beneficial effects:

[0054] When the garbage forms slurry, the second gauze layer 220 drives the slurry to separate solid from liquid, and then the slurry is squeezed by the squeezing disc 209 to squeeze the liquid in the slurry into the diversion ring 219. When the solid-liquid separation is in place, the solid slurry is sent to the second fermentation box 304, and then the liquid slurry flows into the first fermentation box 301. The fourth electric ball valve 306 is opened so that it is in a solid-liquid separation state and a connected state at the same time. When the pressure in the second fermentation box 304 is too high, the liquid in the first fermentation box 301 can also play a role in pressure relief, making the work safer and improving the effect of their separate fermentation after the solid garbage and liquid garbage are separated.

[0055] The first motor 205 is started to drive several groups of stirring rod bodies 20661 to stir. Due to the filling cushion layer arranged on the outer wall of the disc body, the internal gas can be prevented from being lost. In order to improve the stirring effect, the stirring rod body 20661 is driven to rotate by the second motor 2065 to improve the mixing effect. Then the third motor 2067 is started to drive several groups of stirring rod bodies 20661 to stir back and forth. During the stirring process, heat can be dissipated through the constant temperature block 20665 to balance the internal temperature, thereby improving the solid-liquid mixing effect of the garbage raw materials.

[0056] During the fermentation process, the temperature is detected through the first temperature display 303. When the fermentation temperature is too low, the heating block 3076 is started to provide heat. In order to speed up the heating speed, the fourth electric push rod 3073 is started to drive the push plate 3074 to rise, so that the internal pressure increases. When it rises to a specified value, the fifth electric ball valve 3077 is opened to assist in raising the temperature in the fermentation box. When the fermentation temperature is high, the cold air released from the condensation box 3078 is neutralized to make the temperature in the fermentation box at an appropriate level, thereby improving the temperature controllability and the fermentation stability effect.

[0057] The solid slurry is sent into the second fermentation box 304, and then the liquid slurry flows into the first fermentation box 301, and the fourth electric ball valve 306 is opened so that it is in a solid-liquid separation state and a connected state at the same time, so that after the solid waste and liquid waste are separated, the effect of their separate fermentation is improved.

[0062] Open the first electric ball valve to allow the slurry liquid to flow into the diversion ring, and drive the slurry to separate solid and liquid through the second gauze layer, then start the third electric push rod, the third electric push rod drives the squeezing disc to descend, and then squeeze the slurry through the squeezing disc, squeezing the liquid in the slurry into the diversion ring;

[0063] Start the first vacuum pump to drive the second connecting pipe to suck the liquid remaining in the extrusion disc into the vacuum box;

[0064] After the solid-liquid separation is completed, the third electric ball valve is opened to send the separated solid slurry into the second fermentation box through the extrusion disc, and then the second electric ball valve is opened to allow the liquid slurry in the fourth connecting pipe to flow into the first fermentation box;
