Description

Technical Field

[0001] The present application relates to the technical field of equipment for garbage disposal, and more specifically, to a low-energy consumption and high-endurance urban garbage disposal device and a method for using the same. Background Art

[0002] As urban populations expand and become denser, the amount of waste generated daily in cities has also increased significantly. Traditional waste disposal methods, such as incineration and landfill, are no longer sufficient and can cause severe environmental damage. To reduce disposal costs, promote resource utilization, and achieve sustainable development, many cities are turning to low-energy, high-endurance urban waste disposal systems.

[0003] The document with prior art publication number CN206430130U provides a low-energy and environmentally friendly garbage disposal equipment. The device sets a first furnace body and a second furnace body and sets a combustion chamber in the second furnace body, so that the temperature in the combustion chamber is more concentrated, the heat source is fully utilized, and the supply of external heat source is reduced. It ensures that the garbage reaches the combustion point when entering the combustion chamber and is fully burned in the combustion chamber, greatly improving the combustion effect. At the same time, the exhaust gas is ash-dropped in the tail smoke preheating chamber, which greatly reduces the dust in the exhaust gas and reduces subsequent work.

[0004] While the aforementioned existing technical solutions can reduce heat loss to a certain extent, they still suffer from the following drawbacks: These solutions utilize a combustion chamber to directly incinerate waste. However, municipal solid waste often contains a large amount of residual moisture, which not only affects the smooth combustion of the waste but also consumes a significant amount of heat, thereby consuming more energy and increasing energy consumption. In view of this, we propose a low-energy, high-endurance municipal solid waste treatment device and its use method. Summary of the Invention

Under the action of the rotating mechanism, the extrusion rollers rotate in opposite directions to squeeze the garbage and squeeze out the water in the garbage. The garbage after squeezing out the water enters the incinerator through the filter cartridge and the discharge pipe, and the wastewater is retained in the collection shell.

[0045] The present application is further described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The embodiment of the present application discloses a low-energy consumption and high-endurance urban garbage treatment device, which includes: a pretreatment shell 1, several feed pipes 4 are installed on one side of the pretreatment shell 1, two squeezing rollers 6 are rotatably connected in the pretreatment shell 1, and a rotating mechanism is also installed on one side of the pretreatment shell 1. The rotating mechanism is used to drive the squeezing rollers 6 to rotate, and a collection shell 2 is installed below the pretreatment shell 1. A filter cartridge 5 is installed in the collection shell 2, and the filter cartridge 5 is densely covered with leakage holes 501. The lower end of the pretreatment shell 1 is fixedly connected to a discharge pipe 12, and the end of the filter cartridge 5 is fixedly connected to a discharge pipe 19. The end of the discharge pipe 19 is connected to the feed port of an external garbage incinerator, and the discharge pipe 12 is connected to the discharge pipe 19.

[0047] The rotating mechanism includes a first motor 11 fixedly mounted on the pretreatment housing 1, the output end of the first motor 11 is fixedly connected to a first gear 13, the end of the squeezing roller 6 is fixedly connected to a second gear 15, the two corresponding second gears 15 are meshed and connected, and the first gear 13 is meshed and connected with one of the second gears 15.

[0048] The staff will feed the urban garbage with a high water content to be processed into between the two squeezing rollers 6 through the feed pipe 4. Under the action of the first motor 11, the first gear 13 rotates. Since the first gear 13 is meshed and connected with one of the second gears 15 and the two corresponding second gears 15 are meshed and connected, the second gear 15 will drive the two squeezing rollers 6 to rotate in opposite directions, squeezing the garbage and squeezing out the water in the garbage. The garbage after squeezing out the water enters the incinerator through the filter cartridge 5 and the discharge pipe 19, and the wastewater is trapped in the collection shell 2. In this way, most of the water in the garbage is removed in advance, which can make the incineration of the garbage easier, greatly reduce energy loss, and also improve a certain processing efficiency.

[0049] A sewage pipe 14 is fixedly connected to one side of the collecting shell 2. A water guide plate 20 is also installed in the collecting shell 2. The water guide plate 20 is arranged in an inclined cylindrical structure.

[0050] After passing through the water guide plate 20 , the wastewater will be discharged to the outside through the sewage pipe 14 in a timely manner.

[0051] Reference Figure 3 and Figure 4 An extrusion plate 7 is also installed in the pretreatment shell 1, and a lifting mechanism is installed on one side of the extrusion plate 7. The lifting mechanism is used to drive the extrusion plate 7 to move up and down.

[0052] The lifting mechanism includes a connecting plate 16 rotatably connected to the second gear 15. A through slot 101 is provided on the pretreatment shell 1. A driving frame 18 is slidably connected in the through slot 101. A receiving plate 17 is fixedly connected to one side of the driving frame 18. One side of the connecting plate 16 is restricted by the receiving plate 17 and is rotatably connected to it. The extrusion plate 7 is fixedly connected to the driving frame 18.

[0053] During the rotation of the second gear 15, under the action of the connecting plate 16, the receiving plate 17 will drive the driving frame 18 and the extrusion plate 7 to move back and forth. During the downward movement of the extrusion plate 7, the extrusion plate 7 will push the garbage downward. On the one hand, this can allow the garbage to enter the extrusion roller 6 quickly and smoothly, and on the other hand, it can also improve the effect of squeezing the garbage.

[0054] A plurality of baffle plates 3 are also mounted on the extrusion plate 7 , and the baffle plates 3 are in movable contact with the end of the feed pipe 4 .

[0055] During the downward movement of the extrusion plate 7, the baffle plate 3 will block the end of the feed pipe 4, effectively preventing the garbage in the feed pipe 4 from falling onto the extrusion plate 7, thereby ensuring the smooth operation of this technical solution.

[0056] Reference Figure 2 and Figure 5 The filter cartridge 5 is limited by the collection shell 2 and is rotatably connected thereto. A driving sleeve 26 is rotatably provided on the collection shell 2. The driving sleeve 26 is fixedly connected to the filter cartridge 5. A driving mechanism is installed on one side of the driving sleeve 26. The driving mechanism is used to drive the driving sleeve 26 to rotate. The driving mechanism includes a second motor 21 fixedly mounted on the collection shell 2. The output end of the second motor 21 is fixedly connected to a first bevel gear 25. A second bevel gear 27 is fixedly sleeved on the driving sleeve 26. The first bevel gear 25 is vertically meshed with the second bevel gear 27.

[0057] After the garbage after the initial water discharge enters the filter cartridge 5, the first bevel gear 25 rotates under the action of the second motor 21. Since the first bevel gear 25 is vertically meshed with the second bevel gear 27, the driving sleeve 26 will drive the filter cartridge 5 to rotate rapidly, thereby further dewatering the garbage after the initial water discharge, greatly reducing the water content in the garbage, and further reducing the energy required for incineration of the garbage.

[0058] Reference Figure 5 、 Figure 6 and Figure 7 A driving shaft 22 is rotatably installed in the driving sleeve 26, and the end of the driving shaft 22 passes through the filter cartridge 5 and extends to the inner cavity of the discharge pipe 19. A driving mechanism is installed on one side of the driving shaft 22, and the driving mechanism is used to drive the driving shaft 22 to rotate. A plurality of stirring rods 23 are fixedly installed on one side of the driving shaft 22, and a auger blade 8 is also fixed on the other side of the driving shaft 22.

[0059] The driving mechanism includes a fixing frame 24 fixedly mounted on the collecting shell 2, and a third bevel gear 28 is rotatably connected to the fixing frame 24, and the third bevel gear 28 is vertically meshed with the first bevel gear 25. A ratchet 29 is also sleeved and fixed on the driving shaft 22, and a plurality of claws 10 are hinged on the inner side of the third bevel gear 28, and the claws 10 are engaged with the ratchet 29. A spring 9 is fixedly connected between the claws 10 and the third bevel gear 28.

[0060] When the second motor 21 runs to one side, the claw 10 slides on the ratchet 29, and the driving sleeve 26 rotates at this time, while the driving shaft 22 and the auger blade 8 are in a stationary state, which can prevent sewage or garbage that has not been completely dewatered from entering the garbage incinerator during the garbage dewatering process; and when the second motor 21 runs to the other side, the claw 10 will be clamped on the outside of the ratchet 29, and the auger blade 8 and the stirring rod 23 will rotate. After the stirring rod 23 stirs up the stuck garbage, the auger blade 8 rotates to smoothly input the stirred garbage into the external garbage incinerator. After the garbage is stirred, the contact area between the garbage and oxygen can be increased, and the difficulty of combustion can be further reduced.

[0061] The method for using the low-energy consumption and high-endurance urban garbage treatment device described in this embodiment includes the following steps:

[0062] S1. A staff member feeds the municipal waste with a high water content to be processed into the space between the two squeezing rollers 6 through the feed pipe 4. Under the action of the first motor 11, the two squeezing rollers 6 rotate in opposite directions to squeeze the waste and squeeze out the water in the waste. The waste after squeezing out the water enters the filter cartridge 5 through the discharge pipe 12.

[0063] S2: During the rotation of the second gear 15, the receiving plate 17 drives the driving frame 18 and the extrusion plate 7 to move up and down reciprocatingly. During the downward movement of the extrusion plate 7, the extrusion plate 7 pushes the garbage downward;

[0064] S3, during the downward movement of the extrusion plate 7, the baffle plate 3 blocks the end of the feed pipe 4;

[0065] S4, when the second motor 21 moves to one side, the driving sleeve 26 drives the filter cartridge 5 to rotate rapidly, further removing water from the garbage after the initial water discharge;

[0066] S5. After the garbage in the filter cartridge 5 is dehydrated, the second motor 21 runs to one side, the auger blades 8 and the stirring rod 23 rotate, and the stirring rod 23 stirs up the garbage stuck together, and the auger blades 8 rotate to smoothly input the stirred garbage into the external garbage incinerator.

[0067] The implementation principle of a low-energy consumption and high-endurance urban garbage treatment device in an embodiment of the present application is as follows: when relevant staff need to use this technical solution to treat garbage with a high water content, the staff first puts the urban garbage with a high water content to be treated into between the two squeezing rollers 6 through the feed pipe 4. Under the action of the first motor 11, the first gear 13 rotates. Since the first gear 13 is meshed and connected with one of the second gears 15 and the two corresponding second gears 15 are meshed and connected, the second gear 15 will drive the two squeezing rollers 6 to rotate in opposite directions, squeeze the garbage, and squeeze out the water in the garbage. The garbage after squeezing out the water enters the filter cartridge 5 through the discharge pipe 12.

[0068] During the rotation of the second gear 15, under the action of the connecting plate 16, the receiving plate 17 will drive the driving frame 18 and the extrusion plate 7 to move up and down. During the downward movement of the extrusion plate 7, the extrusion plate 7 will push the garbage downward. On the one hand, it can allow the garbage to enter the extrusion roller 6 quickly and smoothly, and on the other hand, it can also improve the effect of squeezing the garbage.

[0069] During the downward movement of the extrusion plate 7, the baffle plate 3 will block the end of the feed pipe 4, effectively preventing the garbage in the feed pipe 4 from falling onto the extrusion plate 7.

[0070] Subsequently, the second motor 21 runs to one side and the first bevel gear 25 rotates. Since the first bevel gear 25 is vertically meshed with the second bevel gear 27, the driving sleeve 26 will drive the filter cartridge 5 to rotate rapidly, thereby further dewatering the garbage after the initial water discharge, greatly reducing the water content in the garbage.

[0071] After the garbage in the filter cartridge 5 is dewatered, the second motor 21 rotates to one side, the claw 10 engages with the outside of the ratchet 29, and the auger blade 8 and the stirring rod 23 rotate. After the stirring rod 23 stirs up the stuck garbage, the auger blade 8 rotates to smoothly feed the stirred garbage into the external garbage incinerator. In this way, subsequent garbage treatment can be carried out with low energy consumption.
