Description

Technical Field

[0001] The present invention relates to the technical field of domestic waste degradation treatment, and in particular to a device for degrading and treating urban domestic waste. Background Art

[0002] Food waste accounts for a significant portion of my country's annual garbage output. Composed primarily of organic matter, this waste is prone to rancidity, breeding mosquitoes and flies, and producing bacteria. It is a significant source of pollution in our living environment and poses a serious threat to public health. Due to its complex composition, large distribution volume, and high water, oil, and salt content, food waste has become a core challenge in many integrated resource recovery projects, including waste incineration. Current methods for degrading domestic waste include landfill, incineration, and microbial degradation.

[0003] At present, when microbial degradation is adopted, a degradation bin is used. The degradation bin currently used is usually made of bricks and concrete. Workers pile domestic waste inside the degradation bin, and then degrade it under the action of microorganisms. During degradation, in order to ensure that the domestic waste is fully exposed to oxygen and to break the original stacking structure of the domestic waste so that air can better enter the domestic waste and improve the uniformity of the supply, the workers will turn the domestic waste through a compost turner. Due to the large size of the compost turner, the maintenance cost is high, and the operation of the compost turner in a small space may be limited and cannot fully play its role. The compost turner requires a special driver, and ordinary workers cannot complete the turning. It is inconvenient for workers to turn the domestic waste inside the degradation bin. At the same time, after degradation is completed, impurities (metals, stones, etc.) that have not been completely decomposed need to be screened and removed. The currently used degradation bin cannot screen and remove impurities that have not been completely decomposed when turning the material, and subsequent secondary treatment is required, which increases the overall workload and reduces the overall degradation efficiency.

[0043] Example

[0044] like Figures 1-16 As shown, a municipal domestic waste degradation and treatment equipment includes a degradation bin 4 and a vertical plate 5. The top two sides of the degradation bin 4 are fixedly connected to the vertical plates 5. One end of the vertical plate 5 is rotatably connected to a screw 7. One end of the screw 7 is fixedly connected to a fifth motor 6 through a main shaft, and the fifth motor 6 is fixedly connected to the vertical plate 5. The outer side of the screw 7 is spirally connected to a slider 9, and the slider 9 is slidably connected to the degradation bin 4. There are two screws 7, and they are symmetrically distributed on both sides of the vertical center line of the degradation bin 4. Two sliders 9 are provided on the outer side of each screw 7, and the inner side of the slider 9 is slidably connected to a guide shaft 8, and the guide shaft 8 is fixedly connected to the vertical plate 5. One end of the slider 9 is fixedly connected to a flipping mechanism 1, and one end of the flipping mechanism 1 is fixedly connected to a screening mechanism 3. One end of the degradation bin 4 is provided with an oxygenation mechanism 2 symmetrical about the vertical center line of the degradation bin 4. The fifth motor 6 can move the slider 9 along the degradation bin 4 through the screw 7, and the slider 9 will also move the flipping mechanism 1 inside the degradation bin 4.

[0045] As a further improvement of the present invention, Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the flipping mechanism 1 includes a first electric telescopic rod 104 fixedly connected to the slider 9, and the number of the first electric telescopic rods 104 corresponds to the number of the sliders 9, wherein the top ends of two first electric telescopic rods 104 are fixedly connected to a first fixed plate 102, and the top ends of the other two first electric telescopic rods 104 are fixedly connected to a second fixed plate 103 arranged in an "L" shape. A belt conveyor 101 is placed inside the degradation bin 4, and the belt conveyor 101 is fixed to the first fixed plate 102 and the second fixed plate 103 on both sides through its own frame. The belt conveyor 101 is connected to the screening mechanism 3, and one end of the belt conveyor 101 is rotatably connected to the shovel plate 110. One end of the shovel plate 110 is rotatably connected to the second electric telescopic rod 109. The second electric telescopic rod 109 is rotatably connected to the belt conveyor 101. One end of the belt conveyor 101 is provided with a toggle assembly. When the domestic garbage inside the degradation bin 4 needs to be turned over, the belt conveyor 101 is operated. At the same time, the shovel plate 110 is first in a state of being moved under the action of the second electric telescopic rod 109. The first electric telescopic rod 104 is in a horizontal state, and at the same time, the first fixed plate 102 and the second fixed plate 103 are used to move the belt conveyor 101 and the shovel plate 110 in the vertical direction, so that the shovel plate 110 can shovel and turn over the domestic garbage piled together in layers. When the shovel plate 110 moves to a suitable position, the belt conveyor 101 shovels the shovel plate 110 into the inside of the domestic garbage, and then the second electric telescopic rod 109 is used to rotate with the shovel plate 110 towards the belt conveyor 101, so that the domestic garbage can be turned over along the shovel plate 110. The belt conveyor 101 slides in the direction of the belt conveyor 101, and at the same time, the belt conveyor 101 will first transport the domestic garbage to the top of the belt conveyor 101, and then drop the domestic garbage from the top of the belt conveyor 101 to the ground, thereby completing the turning of the domestic garbage. The belt conveyor 101 and the shovel 110 turn the domestic garbage layer by layer from top to bottom, so that the domestic garbage at the bottom and the domestic garbage at the top can be switched back and forth, thereby ensuring that each part of the domestic garbage can fully contact with oxygen, thereby improving the efficiency and effect of degradation.

[0046] As a further improvement of the present invention, Figure 4 、 Figure 5 and Figure 7As shown, the toggle assembly includes an L-shaped fixed rod 105 fixedly connected to the frame of the belt conveyor 101 itself, one end of the fixed rod 105 is rotatably connected to a roller 107, and the outer side of the roller 107 is fixedly connected to a toggle rod 108 set at intervals, one end of the roller 107 is fixedly connected to a first motor 106 through a main shaft, and the first motor 106 is fixedly connected to the fixed rod 105. During the period when the belt conveyor 101 transports domestic waste, the first motor 106 will rotate clockwise with the roller 108 and the toggle rod 108, so that the toggle rod 108 can toggle the domestic waste on the surface of the shovel plate 110 toward the belt conveyor 101, thereby improving the transportation efficiency of the belt conveyor 101 and ensuring that domestic waste will not remain on the surface of the shovel plate 110.

[0047] As a further improvement of the present invention, Figure 2 、 Figure 4 、 Figure 8 and Figure 9As shown, the screening mechanism 3 includes a first side plate 301 and a second side plate 302 fixedly connected to the frame of the belt conveyor 101 itself, one end of the second side plate 302 is fixedly connected to the third motor 303, the end of the main shaft of the third motor 303 is fixedly connected to the screening net 308, and the other end of the screening net 308 is rotatably connected to the first side plate 301. When the screening net 308 is not needed, the screening net 308 is stored on the back of the belt conveyor 101 to ensure that the screening net 308 does not affect the normal turning of domestic garbage by the belt conveyor 101 When the screening net 308 is needed to screen the impurities in the domestic garbage, the screening net 308 is placed at the unloading position of the belt conveyor 101 to ensure that the domestic garbage dropped from the belt conveyor 101 can fall to the inner side of the screening net 308. A limiting component is provided at one end of the first side plate 301. The top of the screening net 308 is fixedly connected to a fixing frame 309. The inner side of the fixing frame 309 is slidably connected to a guide column 316. There are two guide columns 316, which are symmetrically distributed on both sides of the vertical center line of the fixing frame 309. The inner side is slidably connected to a horizontal plate 318, and a first spring 317 is provided on the outer side of the guide column 316, and the two ends of the first spring 317 are fixedly connected to the fixed frame 309 and the horizontal plate 318 respectively. The second spring 317 gives the horizontal plate 318 an upward pulling force, and the bottom end of the horizontal plate 318 is fixedly connected to a guide cylinder 319. The inner side of the guide cylinder 319 is slidably connected to a rod 320. The rod 320 will crush the lumpy degradation products in the degradation products, thereby facilitating the degradation products to fall from the screening net 308. The top of the fixed frame 309 is provided with a pressing group. A secondary breaking up component is provided at one end of the fixed frame 309. After degradation and fermentation, the domestic waste will form granular or lumps for transportation. When the domestic waste needs to be screened after the degradation and fermentation is completed, when the domestic waste falls to the inner side of the screening net 308, the granular degradation products will pass through the screening net 308 and fall to the inner side of the degradation bin 4, so that the undegraded metals, stones and other impurities in the degradation products are removed under the screening action of the screening net 308, and no subsequent secondary screening is required, which reduces the overall workload and improves the overall degradation efficiency.

[0048] As a further improvement of the present invention, Figure 8 and Figure 10As shown, the pressing assembly includes a support base 310 fixedly connected to the fixing frame 309, the top of the support base 310 is fixedly connected to a double-output shaft motor 311, and the main shaft ends of both ends of the double-output shaft motor 311 are respectively fixedly connected to a first cam 312 and a second cam 313, and a guide wheel 315 is movably provided below the first cam 312 and the second cam 313, and the outer side of the guide wheel 315 is rotatably connected to a connecting base 314, and the connecting base 314 is fixedly connected to a guide column 316. After the degradation product falls to the inner side of the screening net 308, the double-output shaft motor 311 will also rotate with the first cam 312 and the second cam 313 at the same time, and the first cam 312 and the second cam 313 can The guide post 316 is pressed downward by the guide wheel 315 and the connecting seat 314, so that the guide post 316 brings the guide cylinder 319 and the insertion rod 320 downward through the cross plate 318 to crush the lumpy degradation products, thereby facilitating the degradation products to fall from the screening net 308 and preventing the lumpy degradation products from accumulating on the inner side of the screening net 308. The first cam 312 and the second cam 313 are arranged in opposite directions. When the second cam 313 presses the guide wheel 315 downward, the first cam 312 does not press the guide wheel 315 downward, thereby ensuring that the insertion rod 320 located below the first cam 312 and the insertion rod 320 located below the second cam 313 move downward alternately, thereby improving the crushing effect.

[0049] As a further improvement of the present invention, Figure 8 and Figure 11 As shown, the secondary breaking up assembly includes a third fixed plate 323 fixedly connected to the fixed frame 309, one end of the third fixed plate 323 is fixedly connected to the fourth motor 324, the end of the main shaft of the fourth motor 324 is fixedly connected to the cross bar 325, and the bottom end of the cross bar 325 is fixedly connected to the stirring rod 326. When the lumps of degradation products pass through the insertion rod 320 and there are still some lumps of degradation products that have not been crushed, the fourth motor 324 will also rotate with the stirring rod 326 through the cross bar 325. The reciprocating collision between the stirring rod 326 and the lumps of degradation products breaks up the lumps of degradation products, thereby further improving the breaking up effect, allowing the degradation products to quickly pass through the screening net 308, and large impurities such as metals and stones remain on the inner side of the screening net 308.

[0050] As a further improvement of the present invention, Figure 8As shown, the limiting assembly includes a turntable 304 fixedly connected to the rotating shaft of the screening net 308, a socket 305 is provided on the outer side of the turntable 304, one end of the first side panel 301 is fixedly connected to the support block 306, one end of the support block 306 is fixedly connected to the fourth electric telescopic rod 307, and the fourth electric telescopic rod 307 is engaged with the turntable 304 through the socket 305. When the screening net 308 is adjusted to a suitable position, the fourth electric telescopic rod 307 is inserted into the inner side of the socket 305, and the screening net 308 is further limited and fixed by the fourth electric telescopic rod 307 to ensure the stability of the screening net 308 during operation.

[0051] As a further improvement of the present invention, Figure 12 As shown, the top of the insertion rod 320 is fixedly connected to the limiting plate 321, and the limiting plate 321 is slidably connected to the guide cylinder 319. The top of the limiting plate 321 is fixedly connected to the second spring 322, and the second spring 322 is fixedly connected to the guide cylinder 319. The second spring 322 gives the insertion rod 320 a downward elastic force through the limiting plate 321. When the insertion rod 320 touches impurities such as metal and stone downward, under the limiting action of the metal and stone, the insertion rod 320 will retract toward the inside of the guide cylinder 319, thereby ensuring that the cross plate 318 moves downward normally, and then ensuring the normal operation of the remaining insertion rods 320.

[0052] As a further improvement of the present invention, Figure 13 、 Figure 14 、 Figure 15 and Figure 16As shown, the oxygenation mechanism 2 includes a fixed block 201 fixedly connected to the degradation bin 4, one end of the fixed block 201 is fixedly connected to the second motor 202, the end of the main shaft of the second motor 202 is fixedly connected to the connecting frame 203, the inner side of the connecting frame 203 is fixedly connected to the inner cylinders 207 arranged in a row, and the adjacent inner cylinders 207 are connected by pipes, one end of the inner cylinder 207 is connected to a connecting pipe 211, one end of the connecting pipe 211 is connected to a vent pipe 212, and the vent pipe 212 is connected to an external air source, a second air outlet 210 is provided on the inner side of the inner cylinder 207, a baffle 209 is fixedly connected to the inner side of the second air outlet 210, and a protective component is provided on the outer side of the inner cylinder 207. When air needs to be injected into the inside of the domestic garbage, the second motor 202 drives the connecting frame 203 to flip toward the inside of the degradation bin 4, and at the same time, the connecting frame 203 will also drive the inner cylinder 2 07 is inserted into the stacked domestic garbage, and then the air can be injected into the stacked domestic garbage through the inner cylinder 207 through the ventilation pipe 212 and the connecting pipe 211. The inner cylinders 207 at different positions can introduce air into different parts of the stacked domestic garbage, ensuring that the air can be evenly distributed to each area, ensuring the uniformity of oxygen supply, avoiding air concentration in a certain area, improving the utilization rate of oxygen, and meeting the use of large-volume degradation bins 4. At the same time, the baffle 209 can prevent domestic garbage from entering the inner side of the inner cylinder 207 and causing the inner cylinder 207 to be blocked, and when it is necessary to turn over the domestic garbage or move the degraded domestic garbage out from the inner side of the degradation bin 4, the connecting frame 203 and the inner cylinder 207 can be flipped to the side of the degradation bin 4 to ensure that the connecting frame 203 and the inner cylinder 207 will not affect the work of the staff and the belt conveyor 101.

[0053] As a further improvement of the present invention, Figure 13 、 Figure 14 and Figure 15 As shown, the protective assembly includes a third electric telescopic rod 204 fixedly connected to the connecting frame 203, the bottom end of the third electric telescopic rod 204 is fixedly connected to a movable plate 205, the inner side of the movable plate 205 is fixedly connected to an outer cylinder 206, the outer cylinder 206 is slidably connected to the inner cylinder 207, and a first air outlet 208 is provided on the outer side of the outer cylinder 206. Before the domestic garbage is inserted into the inner cylinder 207, the first air outlet 208 on the surface of the outer cylinder 206 is staggered with the baffle 209 to ensure that the domestic garbage is inserted into the inner cylinder 207. When the inner tube 207 is inserted, the barrier net 209 will not come into direct contact with the domestic waste, preventing the extrusion force generated between the barrier net 209 and the domestic waste during the insertion process from squeezing part of the domestic waste into the inner side of the inner tube 207 through the mesh of the barrier net 209, thereby reducing the probability of domestic waste entering the inner tube 207. When the inner tube 207 needs to output air, the first air outlet 208 is aligned with the barrier net 209, so that the air in the inner tube 207 can pass through the barrier net 209 and the first air outlet 208 and enter the inner side of the domestic waste.

[0054] Working process: When it is necessary to turn over the domestic garbage inside the degradation bin 4, the belt conveyor 101 is operated, and at the same time, the shovel plate 110 is first placed in a horizontal state under the action of the second electric telescopic rod 109, and at the same time, the first electric telescopic rod 104 is moved in the vertical direction with the belt conveyor 101 and the shovel plate 110 through the corresponding first fixed plate 102 and the second fixed plate 103, so that the shovel plate 110 can shovel up and turn over the domestic garbage stacked together in layers. When the shovel plate 110 moves to the appropriate position, the belt conveyor 101 shovels the shovel plate 110 into the inside of the domestic garbage, and then the second electric telescopic rod 109 is rotated with the shovel plate 110 in the direction close to the belt conveyor 101, so that the domestic garbage can slide along the shovel plate 110 toward the belt conveyor 101, and the belt conveyor 101 transports the domestic garbage. During this period, the first motor 106 will rotate clockwise by driving the roller 108 and the lever 108, so that the lever 108 can shift the domestic garbage on the surface of the shovel plate 110 toward the belt conveyor 101, thereby improving the transportation efficiency of the belt conveyor 101 and ensuring that the domestic garbage will not remain on the surface of the shovel plate 110. The belt conveyor 101 first transports the domestic garbage to the high position of the belt conveyor 101, and then causes the domestic garbage to fall from the high position of the belt conveyor 101 to the ground, thereby completing the turning of the domestic garbage. The belt conveyor 101 and the shovel plate 110 turn over the domestic garbage layer by layer from top to bottom, so that the domestic garbage at the bottom and the domestic garbage at the top can be switched back and forth, thereby ensuring that each part of the domestic garbage can be fully exposed to oxygen, thereby improving the efficiency and effect of degradation.

[0055] When it is necessary to inject air into the inside of the domestic garbage, the second motor 202 drives the connecting frame 203 to flip toward the inside of the degradation bin 4. At the same time, the connecting frame 203 also drives the inner cylinder 207 and the outer cylinder 206 to insert into the domestic garbage stacked together. Before the inner cylinder 207 is inserted into the domestic garbage, the first air outlet 208 on the surface of the outer cylinder 206 is staggered with the baffle 209 to ensure that when the inner cylinder 207 is inserted into the domestic garbage, the baffle 209 will not directly contact the domestic garbage, and the extrusion force generated between the baffle 209 and the domestic garbage during the insertion process will prevent part of the domestic garbage from being squeezed into the inner side of the inner cylinder 207 through the mesh of the baffle 209, thereby reducing the probability of domestic garbage entering the inner cylinder 207. When the inner cylinder 207 needs to output air, the first air outlet 208 is aligned with the baffle 209, so that the air in the inner cylinder 207 can pass through the baffle 209 and the first air outlet 208. An air outlet 208 enters the inner side of the domestic garbage, and then the air can be injected into the stacked domestic garbage through the inner cylinder 207 through the ventilation pipe 212 and the connecting pipe 211. The inner cylinders 207 at different positions can introduce air into different parts of the stacked domestic garbage, ensuring that the air can be evenly distributed to each area, ensuring the uniformity of oxygen supply, avoiding air concentration in a certain area, improving the utilization rate of oxygen, and meeting the use of a large-volume degradation bin 4. At the same time, the blocking net 209 can prevent domestic garbage from entering the inner side of the inner cylinder 207 and causing the inner cylinder 207 to be blocked. When it is necessary to turn over the domestic garbage or move the degraded domestic garbage out of the inner side of the degradation bin 4, the connecting frame 203 and the inner cylinder 207 can be turned over to the side of the degradation bin 4 to ensure that the connecting frame 203 and the inner cylinder 207 do not affect the work of the staff and the belt conveyor 101.

[0056] After the degradation and fermentation of domestic waste, it will form granular or lumpy shapes for transportation. When the domestic waste needs to be screened after the degradation and fermentation is completed, the third motor 303 is used to rotate the screening net 308, so that the screening net 308 is at the unloading position of the belt conveyor 101, ensuring that the domestic waste dropped from the belt conveyor 101 can fall to the inner side of the screening net 308. When the screening net 308 is adjusted to a suitable position, the fourth electric telescopic rod 307 is inserted into the inner side of the socket 305, and the fourth electric telescopic rod 307 is used to further realize the limit fixation of the screening net 308, ensuring that the screening net 308 works properly. The stability of the time, then the domestic garbage can be transported to the top of the screening net 308 by the belt conveyor 101. When the domestic garbage falls to the inside of the screening net 308, the granular degradation products will pass through the screening net 308 and fall to the inside of the degradation bin 4, thereby removing the undegraded metals and stones and other impurities in the degradation products under the screening action of the screening net 308, without the need for subsequent secondary screening, reducing the overall workload and improving the overall degradation efficiency. When the degradation products fall to the inside of the screening net 308, the dual-output shaft motor 311 will also drive the first cam 312 and the second cam 313 to move ... The first cam 312 and the second cam 313 rotate at the same time, and both the first cam 312 and the second cam 313 can press the guide post 316 downward through the guide wheel 315 and the connecting seat 314, so that the guide post 316 can carry the guide cylinder 319 and the insertion rod 320 downward through the cross plate 318 to crush the lumps of degradation products, thereby facilitating the degradation products to fall from the screening net 308 and preventing the lumps of degradation products from accumulating on the inner side of the screening net 308. The first cam 312 and the second cam 313 are arranged in opposite directions. When the second cam 313 presses the guide wheel 315 downward, the first cam 312 does not press the guide wheel 315 downward, so that This ensures that the insertion rod 320 located below the first cam 312 and the insertion rod 320 located below the second cam 313 move downward alternately, thereby improving the crushing effect; when the lumps of degradation products pass through the insertion rod 320 and there are still some lumps of degradation products that have not been crushed, the fourth motor 324 will also rotate the stirring rod 326 through the cross bar 325. The reciprocating collision between the stirring rod 326 and the lumps of degradation products breaks up the lumps of degradation products, thereby further improving the breaking effect, allowing the degradation products to pass through the screening net 308 quickly, and large impurities such as metals and stones remain on the inner side of the screening net 308.
