Description

Technical Field

[0001] The invention relates to the field of combustion equipment, and in particular to a device and method for incinerating and purifying urban domestic waste. Background Art

[0002] The amount of urban domestic waste is increasing day by day. Traditional biological landfill not only occupies a large amount of land resources, but also has problems such as slow processing speed, uncertain processing effect and possible harmful methane. Waste incineration technology has gradually become an important means of urban domestic waste treatment due to its characteristics of volume reduction, resource utilization and harmlessness. However, the existing waste incineration purification treatment equipment still has problems in terms of treatment efficiency, tail gas emission control and ash treatment, which are difficult to fully meet the needs of urban waste treatment.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the technical means for waste incineration treatment. In order to make a more accurate comparison, a Chinese patent with publication number CN214172237U discloses a city domestic waste incineration treatment furnace, including a box body, a supporting foot, a first placement fan, an air outlet, a second placement fan, a controller, a power cord, a placement chamber, an adjustment mechanism and a blocking plate, etc.; when in use, the adjustment mechanism drives the piston to move while driving the external gas into the interior of the limit plate through the first one-way valve, and transmits the gas to the bottom end of the box body through the transmission pipe, which can provide oxygen for waste incineration, improve the incineration effect, and further improve the overall incineration rate of the waste; by setting an auxiliary component at the lower end of the placement chamber, when the baffle rotates up and down, the garbage placed in the placement chamber can be intermittently transmitted to the bottom end of the box body, so as to avoid a large amount of garbage from piling up in the box body and avoid insufficient garbage incineration.

[0004] However, when using the above-mentioned prior art to filter vegetable oil, the following problem still exists: the above-mentioned device can intermittently transfer the garbage placed in the placement cavity to the bottom of the box by driving the baffle to rotate up and down, so as to avoid a large amount of garbage from piling up in the box and avoiding insufficient incineration of the garbage. In actual use, the garbage itself has a certain weight. When the baffle is intermittently controlled to be put into the box by the up and down swinging baffle, the swing amplitude of the baffle is certain, which makes it inconvenient to control the falling amount of the garbage put into the box. Therefore, the total amount of garbage put into the box each time will be different. If too much garbage falls into the box during one of the throwing processes, a large amount of garbage will be piled up in the box, resulting in insufficient incineration of the garbage.

[0005] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means of incineration and purification of garbage. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a device for incinerating and purifying urban domestic waste, comprising a placement furnace, wherein a processing component for purifying the waste is arranged in the placement furnace.

[0007] The processing components include:

[0008] The material guiding funnel is located in the placing furnace and on the upper side of the placing furnace.

[0009] The incineration bin is located inside the furnace and below the material guide hopper.

[0010] The regulating end is arranged between the material guiding funnel and the incineration bin and is limited to be placed in the furnace.

[0011] Preferably, the adjustment end includes a limiting ring plate connected to the lower end of the material guide funnel, and a plurality of adjustment plates are evenly connected circumferentially on the limiting ring plate, wherein any one of the adjustment plates is connected to a driving plate, and all the driving plates are commonly connected to an adjustment ring on the side away from the connected adjustment plates.

[0012] Preferably, the adjustment plate is arranged in an arc-shaped structure and allows being driven by a connected driving plate to be assembled into a complete circular structure.

[0013] Preferably, the limiting ring plate is a hollow shape with upper and lower layers in the middle, and all the adjustment plates are slidably limited in the hollow part of the limiting ring plate so as to be assembled into a complete circular structure to adjust the middle ring diameter of the limiting ring plate.

[0014] Preferably, a plurality of guide grooves are provided on the limit ring plate corresponding to the driving paddle, so that the driving paddle can be inserted into the guide grooves accordingly.

[0015] Preferably, a connecting slide rod is provided at the bottom of the incineration bin, a limiting sleeve is sleeved on the connecting slide rod and limited in position in the furnace, and a sliding frame connected to the limiting sleeve is provided on the adjusting ring.

[0016] Preferably, the connecting slide rod is provided with a driven slide block inserted in a limiting sleeve, and the limiting sleeve is provided with a spiral slide groove corresponding to the driven slide block.

[0017] Preferably, an adjusting spring is connected between the connecting slide rod and the inner bottom where the furnace is placed.

[0018] Preferably, the guide funnel is connected downwardly with a connecting conduit so that the high-temperature flue gas in the incineration bin can be introduced into the guide funnel and the wet and sticky garbage therein can be dried and pre-treated.

[0019] In addition, the present invention also provides a method for incinerating and purifying urban domestic waste, comprising the following steps:

[0020] S1: Place domestic waste in an orderly manner into the furnace, and conduct preliminary guidance and screening through the material guide funnel to ensure that the waste enters the incineration bin evenly, preparing for subsequent incineration treatment.

[0021] S2: In the process of introducing domestic waste into the incineration bin, the total amount of waste entering the incineration bin is controlled by adjusting the regulating end to avoid excessive waste to be processed in the incineration bin, resulting in insufficient incineration.

[0022] S3: When the garbage in the incineration bin reaches a certain weight, the incineration bin is automatically closed through the adjustment end to stop the input of garbage, so as to avoid excessive input of garbage, which will cause excessive squeezing and stacking of garbage and lead to incomplete combustion of the garbage.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present invention can adjust and control the relative position between the incineration bin and the material guide hopper according to the actual situation in the incineration bin through the design of the adjustment end, and then control the amount of garbage falling between the incineration bin and the material guide hopper through the cooperation between the adjustment ring, the driving plate, the adjustment plate and the limit ring plate, so as to effectively avoid the problem of insufficient incineration caused by too much garbage being put in at one time.

[0025] 2. The present invention pumps gas into the incineration bin through a plurality of exhaust pipes circumferentially arranged on the incineration bin, thereby providing sufficient oxygen and uniform gas distribution during the process of incinerating garbage in the incineration bin, thereby effectively improving the incineration efficiency of garbage. At the same time, a plurality of exhaust pipes vertically arranged on the side walls of the incineration bin effectively prevent ash from falling into the exhaust pipe and causing exhaust pipe blockage, thereby ensuring the stability of air flow in the incineration bin and reducing pollutant emissions.

[0026] 3. The present invention drives a plurality of exhaust pipes to pump gas into the incineration bin while driving the exhaust pipes themselves to rotate synchronously. The exhaust pipes drive a plurality of inclined exhaust holes arranged thereon to rotate, which not only avoids the problem of too fast flow rate of gas pumped into the incineration bin affecting the incineration environment in the incineration bin, but also avoids the problem of exhaust holes at the same position on the exhaust pipe remaining stationary in the incineration bin for a long time and being easily invaded by ash, causing exhaust pipe blockage, thereby ensuring the continuous supply of gas and further improving the incineration effect and efficiency.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 To Attachment Fig. 9 Embodiments of the present invention are described in detail.

[0039] The embodiment of the present application discloses a device and method for incineration and purification of urban domestic waste, which explains that the present application is mainly used in the process of incineration and purification of urban domestic waste, and technically achieves the effect of incineration and purification of urban domestic waste that needs to be treated; in particular, during the incineration process, the amount of garbage that falls into the incineration bin through the adjusting end is controlled by the material guide funnel, thereby effectively avoiding the problem of insufficient incineration caused by too much garbage being put in at one time; and the incineration treatment device also achieves the effect of uniformly and continuously pumping gas into the incineration bin through the mutual cooperation between the annular air pipe and a plurality of exhaust pipes.

[0040] Example 1: Reference Figure 1 and Figure 2 As shown, a device for incinerating and purifying urban domestic waste includes a placing furnace 1 and a processing assembly 2. The placing furnace 1 is hollow inside and is provided with an opening on one side. An end cap is detachably installed at the opening to allow the domestic waste to be processed to be put in. Then the entire placing furnace 1 is closed. The placing furnace 1 is provided with a processing assembly 2 for purifying the waste. When in use, after the domestic waste to be processed is put into the placing furnace 1, the domestic waste in the placing furnace 1 is incinerated and purified by the processing assembly 2.

[0041] Reference Figures 2 to 4 As shown, the processing component 2 is used for purifying garbage; specifically, the processing component 2 includes:

[0042] The material guiding funnel 20 is located in the placing furnace 1 and at the upper side of the placing furnace 1 .

[0043] The incineration bin 21 is located in the placement furnace 1 and at the lower side of the material guiding funnel 20 .

[0044] The regulating end 22 is disposed between the material guiding funnel 20 and the incineration bin 21 and is limited in the placement furnace 1 .

[0045] When in use, the domestic waste to be processed is first put into the placement furnace 1, and then guided by the material guide funnel 20 to enter the incineration bin 21 for incineration and purification. In the process of incineration treatment of the above-mentioned domestic waste, the amount of garbage introduced into the incineration bin 21 from the material guide funnel 20 is adjusted and controlled by the adjustment end 22 to avoid the problem of excessive domestic waste being put in at one time, resulting in the garbage in the incineration bin 21 not being fully incinerated and purified.

[0046] Reference Figures 2 to 6As shown, the regulating end 22 is used to control the amount of garbage introduced into the incineration bin 21; specifically, the regulating end 22 includes a limiting ring plate 220 that is limitedly connected to the lower end of the guide funnel 20, and a plurality of regulating plates 221 are evenly connected to the limiting ring plate 220 in a circumferential direction, wherein any one of the regulating plates 221 is connected to a driving dial plate 222, and all the driving dial plates 222 are commonly connected to an adjusting ring 223 on the side away from the connected regulating plates 221.

[0047] When in use, all the driving plates 222 are driven to slide and adjust through the adjusting ring 223. The sliding of the driving plates 222 drives the connected adjusting plates 221 to slide synchronously. During the sliding process of the adjusting plates 221, the adjusting plates 221 are slide-adjusted along the limiting ring plates 220, thereby realizing the adjustment and control of the relative positions of all the adjusting plates 221 and the limiting ring plates 220, thereby realizing the effect of controlling the falling amount of garbage falling from the material guide funnel 20 into the incineration bin 21. By controlling the amount of domestic garbage introduced into the incineration bin 21 each time, the problem of excessive domestic garbage being put in at one time, which leads to the garbage in the incineration bin 21 not being fully incinerated and purified, can be avoided.

[0048] Reference Figures 3 to 5 As shown, the adjustment plate 221 is a triangular structure and its three sides are all arc-shaped. A plurality of arc-shaped adjustment plates 221 can be driven by the connected driving plates 222 to form a complete circular structure. When in use, the driving plate 222 is driven to slide by the adjusting ring 223, and the driving plate 222 drives the connected adjustment plate 221 to slide in the limiting ring plate 220. When the driving plate 222 drives the adjustment plates 221 to slide away from each other, the relative distance between the adjustment plate 221 and the limiting ring plate 220 and between the plurality of adjustment plates 221 increases, thereby increasing the amount of garbage falling from the guide hopper 20. On the contrary, when the driving plate 222 drives the adjustment plate 2 When the adjusting plates 21 slide in the direction of approaching each other, the relative distance between the adjusting plate 221 and the limiting ring plate 220 and between several adjusting plates 221 is reduced, thereby reducing the amount of garbage falling at the material guide hopper 20. At the same time, all the adjusting plates 221 are driven to slide in the direction of approaching each other, and after they are jointly resisted and assembled into a complete circular structure, the material guide channel between the material guide hopper 20 and the incineration bin 21 is closed, so as to avoid the problem of smoke leakage and environmental pollution during the incineration process.

[0049] Reference Figures 3 to 5 As shown, the limiting ring plate 220 is a hollowed-out shape with upper and lower layers, and all the adjustment plates 221 are slidably limited in the hollowed-out part of the limiting ring plate 220 so as to be assembled into a complete circular structure to adjust the limiting ring plate 220.

[0050] When in use, the sliding path of all the adjustment plates 221 is limited by the limiting ring plate 220, so that when the driving plate 222 drives the connected adjustment plates 221 to slide, they can slide along the limiting ring plate 220 and thus be assembled together into a complete circular structure, so as to control the material discharge amount of the material guide channel between the material guide funnel 20 and the incineration bin 21, and at the same time to close the incineration bin 21.

[0051] Further, as an optional implementation, refer to Figures 3 to 5 As shown, a plurality of guide grooves 224 are provided on the limiting ring plate 220 corresponding to the driving dial plate 222, so that the driving dial plate 222 is correspondingly inserted in the guide groove 224, and the adjustment plate 221 and the limiting ring plate 220 as well as the adjustment plate 221 and the connected driving dial plate 222 are rotatably arranged, and the rotation axes between the adjustment plate 221 and the limiting ring plate 220 and the adjustment plate 221 and the driving dial plate 222 correspond to the two ends of the adjustment plate 221 respectively, and at the same time, the end of the driving dial plate 222 away from the connected adjustment plate 221 is rotatably connected to the adjustment ring 223.

[0052] Based on the above, when in use, since the limiting ring plate 220 is connected to the material guide hopper 20, after driving the adjusting ring 223 to rotate, the adjusting ring 223 rotates and drives all the driving dial plates 222 to rotate and slide synchronously, and the driving dial plate 222 rotates and slides to drive one end of the connected adjusting plate 221 to rotate and slide. At this time, since one end of the adjusting plate 221 is rotatably connected to the limiting ring plate 220, after the driving dial plate 222 pulls the connected adjusting plate 221 to slide, the adjusting plate 221 is driven to deflect with the rotation axis between the limiting ring plate 220 and the limiting ring plate 220 as the axis. If all the adjusting plates 221 are deflected in the direction of approaching each other, the falling amount of the material guide hopper 20 is reduced and the material guide channel between the incineration bin 21 and the material guide hopper 20 is closed at the same time. If all the adjusting plates 221 are deflected in the direction of moving away from each other, the effect of increasing the falling amount of garbage at the material guide hopper 20 is achieved.

[0053] Reference Figures 3 to 5 As shown, an annular groove 225 is provided on one side of the inner edge of the adjusting ring 223 for guiding and limiting the sliding path of all the driving plates 222. After the adjusting ring 223 rotates to drive the driving plates 222 to rotate and deviate, the driving plates 222 deflect around the rotation axis between the adjusting ring 223 and the adjusting ring 223. During the deflection process, the driving plates 222 slide along the side walls of the annular groove 225.

[0054] Reference Figures 3 to 6As shown, a connecting slide rod 23 is provided at the bottom of the incineration bin 21, and a limiting sleeve 230 is sleeved on the connecting slide rod 23 and is rotatably connected to the inner bottom wall of the placement furnace 1. A sliding frame 231 connected to the limiting sleeve 230 is provided on the adjusting ring 223, and a telescopic support rod connected to the inner bottom wall of the placement furnace 1 is also symmetrically provided at the bottom of the incineration bin 21.

[0055] When in use, after a certain amount of garbage is introduced into the incineration bin 21, the incineration bin 21 and the connecting slide rod 23 are driven to move downward as a whole, and the sliding frame 231 and the adjusting ring 223 are driven to rotate simultaneously, so as to control all the adjusting plates 221 on the limiting ring plate 220 to be pressed together and assembled into a complete circular structure to complete the effect of sealing the material guide funnel 20.

[0056] Reference Figures 3 to 5 As shown, the connecting slide bar 23 is provided with a driven slide bar 232 inserted in the limiting sleeve 230, and the limiting sleeve 230 is provided with a spiral groove 233 corresponding to the driven slide bar 232. When in use, the connecting slide bar 23 moves downward to drive the connected driven slide bar 232 to slide synchronously, and the driven slide bar 232 slides along the spiral groove 233 on the limiting sleeve 230, and the limiting sleeve 230 is driven to rotate through the spiral groove 233, and the rotation of the limiting sleeve 230 synchronously drives the sliding frame 231 to rotate, so as to achieve the effect of adjusting and controlling the relative position and distance between the adjusting plate 221 and the limiting ring plate 220.

[0057] Reference Figures 3 to 5 As shown, an adjusting spring 24 is commonly connected between the connecting slide bar 23 and the inner bottom of the placement furnace 1. When in use, when the incineration bin 21 is filled with domestic garbage to be processed, the unburned garbage and the incineration bin 21 move downward under the influence of their own gravity, so that the adjusting spring 24 is compressed. After the garbage is incinerated, its overall mass is reduced. The adjusting spring 24 needs to be stretched again due to being compressed, so the incineration bin 21 is driven to move up again. The upward movement of the incineration bin 21 drives the connecting slide bar 23 and the driven slider 232 to move up synchronously, driving the sliding frame 231 and the adjusting ring 223 to rotate in the opposite direction, and a plurality of adjusting plates 221 slide in a direction away from each other to reopen the guide hopper 20 so as to continue to put the garbage to be processed into the incinerator.

[0058] It should be noted that since a large amount of polluted flue gas will be generated during the incineration of domestic waste, a gas collecting pipe should be connected to the furnace 1 when in use, and the gas collecting pipe is connected to the external flue gas purification equipment.

[0059] Example 2: Reference Figures 6 to 9As shown, on the basis of the first embodiment, in order to improve the efficiency and effect of the incineration bin 21 in incinerating and purifying domestic waste, an auxiliary component 3 is further arranged in the furnace 1 for convenience. Specifically, the auxiliary component 3 includes an annular air pipe 30 connected to the incinerator, and the annular air pipe 30 is connected to an air guide pipe 31 which passes through the incineration bin 21 and the furnace 1 at the same time. The air guide pipe 31 is bent and allows telescopic sliding in the vertical direction. The annular air pipe 30 is also circumferentially evenly connected to a plurality of exhaust pipes 32 limited on the incineration bin 21, and a plurality of exhaust holes 320 are evenly opened circumferentially on the exhaust pipe 32.

[0060] During use, gas is pumped into the air guide pipe 31 and the annular air pipe 30 through external equipment such as an air pump. After the gas is pumped into the annular air pipe 30, it is discharged along a number of exhaust pipes 32 connected to the annular air pipe 30, and then enters the incineration bin 21 to provide oxygen during the incineration and purification of garbage, thereby improving the incineration effect. Moreover, since a number of exhaust pipes 32 are arranged on the incineration bin 21, when the gas enters the incineration bin 21, it is passed into the incineration bin 21 along the side of the incineration bin 21, thereby effectively avoiding the problem of garbage ash blocking the exhaust pipe 32 during the incineration process. At the same time, through a number of exhaust pipes 32 circumferentially distributed on the side wall of the incineration bin 21, the gas entering the incineration bin 21 is more evenly distributed, thereby further improving the overall incineration rate of the garbage, and avoiding the problem that the unilateral introduction of gas causes a large disturbance to the overall air flow in the incineration bin 21, thereby affecting the garbage incineration efficiency.

[0061] Further, refer to Figures 6 to 9 As shown in the figure, during use, since the exhaust hole 320 on the exhaust pipe 32 is in contact with the ash after incineration in the incineration bin 21 for a long time, it is inevitable that part of the ash will be sucked into the exhaust pipe 32, and then over time, the exhaust of the exhaust pipe 32 is not smooth, which affects the air conduction rate, thereby causing the problem of insufficient combustion of the garbage in the incineration bin 21. In order to avoid the above problem, the exhaust pipe 32 is vertically inserted into the side wall of the incineration bin 21 as a whole, and the exhaust pipe 32 is connected to the inner wall of the incineration bin 21 corresponding to the exhaust pipe 32. The air pipe 32 is formed with a plurality of rectangular grooves 33 to limit the number of exhaust holes 320 on the exhaust pipe 32 connected to the incineration bin 21. A mounting ring 34 is connected to the upper end of the exhaust pipe 32. The inner edge diameter of the mounting ring 34 is smaller than the diameter of the exhaust pipe 32. A limiting conduit 35 is connected between the exhaust pipe 32, the mounting ring 34 and the annular air pipe 30. The limiting conduit 35 is rotatably connected to the mounting ring 34 and the exhaust pipe 32. At the same time, the plurality of exhaust holes 320 on the exhaust pipe 32 are also bent and inclined.

[0062] When in use, after gas is pumped into the air guide pipe 31 and the annular air pipe 30 through external equipment, since the several exhaust holes 320 on the exhaust pipe 32 are bent and inclined, the gas discharged through the exhaust holes 320 will push the corresponding exhaust pipe 32 and the mounting ring 34 to rotate, thereby outputting gas to the incineration bin 21 through the exhaust pipe 32, and at the same time driving the exhaust pipe 32 itself to rotate continuously, so as to avoid the problem that the exhaust holes 320 on any side of the exhaust pipe 32 remain stationary in the incineration bin 21 for a long time and are easily blocked by ash.

[0063] Example 3: Reference Figures 6 to 9 As shown, on the basis of the first and second embodiments, the guide funnel 20 is connected downwardly with a connecting conduit 4, two limiting rings 40 are arranged at intervals from top to bottom in the connecting conduit 4, a driven protrusion 41 is slidably inserted in the connecting conduit 4, and a blocking block 42 is fitted on the driven protrusion 41 corresponding to the two limiting rings 40, and the outer diameters of the blocking block 42 and the driven protrusion 41 are smaller than the inner diameters of the two limiting rings 40, and a guide air pipe 43 arranged coaxially with the connecting conduit 4 is also connected to the annular air pipe 30, The connecting conduit 4 is also horizontally connected to a guide air pipe 44 that passes through the material guide funnel 20. The guide air pipe 44 is connected to a mounting plate 45 that is limitedly located at the lower outlet of the material guide funnel 20. The mounting plate 45 is also connected to a drainage air pipe 46 that is connected to the material guide funnel 20 on one side away from the guide air pipe 44. A driven rotating rod 47 is passed through the mounting plate 45. An impeller 48 located in the mounting plate 45 is sleeved on the driven rotating rod 47. The driven rotating rod 47 is also connected to a stirring frame 49 located in the material guide funnel 20.

[0064] When in use, after gas is pumped into the annular air pipe 30, a part of the gas entering the annular air pipe 30 is passed into the incineration bin 21 through a number of exhaust pipes 32, and the other part is discharged upward through the guide air pipe 44, and then blown into the connecting duct 4 and the material guide funnel 20, so as to achieve the effect of air-drying the wet sticky garbage to be processed in the material guide funnel 20, so as to avoid the problem of different incineration rates among the garbage in the incineration bin 21 caused by the evaporation of water vapor on the wet sticky garbage after the wet sticky garbage is subsequently introduced into the incineration bin 21, thereby reducing the problem of increased smoke volume and pollutants caused by excessively high water content of the garbage.

[0065] It should be noted that, since the driven protrusion 41 and the blocking block 42 have a certain dead weight, when the gas is not pumped in initially, the driven protrusion 41 and the blocking block 42 move downward freely due to their own gravity, so that one of the blocking blocks 42 located on the upper side is pressed against and fitted together with the limiting ring 40 on the lower side to form a closure on the connecting duct 4. When the gas is discharged from the guide air pipe 43 to form an upward airflow, the airflow entering the connecting duct 4 will drive the driven protrusion 41 and the blocking block 42 to move upward until the two blocking blocks 42 are correspondingly fitted on the two limiting rings 40. At this time, the airflow entering the connecting duct 4 will enter the mounting plate 45 along the guide air pipe 44, and then blow the impeller 48 in the mounting plate 45 to rotate. The rotation of the impeller 48 drives the driven rotating rod 47 and the stirring frame 49 to rotate, thereby stirring the garbage to be processed in the guide funnel 20, thereby promoting water evaporation and improving the air-drying effect.

[0066] Furthermore, since the gas continues to flow from the annular air pipe 30 toward the guide air pipe 43 and the connecting conduit 4, during the flow process, the high-temperature flue gas generated during the incineration in the incineration bin 21 will be attracted by the flowing airflow and introduced into the material guide funnel 20, thereby preheating, drying and air-drying the wet and sticky garbage in the material guide funnel 20, effectively improving the efficiency of the subsequent incineration treatment of domestic garbage.

[0067] Furthermore, when the amount of garbage in the incineration bin 21 reaches a certain amount, the incineration bin 21, the annular air pipe 30 and the guide air pipe 43 move downward as a whole, so that a distance is generated between the guide air pipe 43 and the connecting duct 4. At this time, the overall pressure of the air flow blown into the connecting duct 4 will become smaller, so that the driven protrusion 41 and the blocking block 42 in the connecting duct 4 move upward but not completely upward to fit the limiting ring 40. At this time, the airflow between the connecting duct 4, the guide air pipe 44, the mounting plate 45, the drainage air pipe 46 and the material guide funnel 20 is connected to each other.

[0068] When the incineration bin 21 moves upward to continue to introduce garbage into it, the guide air pipe 43 moves upward accordingly and is slidably inserted into the connecting duct 4. At this time, the pressure of the airflow blown into the connecting duct 4 increases, and drives the blocking block 42 to move upward and fit on the limiting ring 40 to form a closure on the connecting duct 4. At this time, the airflow will be introduced into the mounting plate 45 and the drainage air pipe 46 along the guide air pipe 44, and then enter the material guide funnel 20, and drive the impeller 48, the driven rotating rod 47 and the stirring frame 49 to rotate, so as to stir the garbage in the material guide funnel 20 and make it fall into the incineration bin 21 to be incinerated and purified.

[0069] In addition, the present invention also provides a method for incinerating and purifying urban domestic waste, comprising the following steps:

[0070] S1: Put the domestic garbage into the furnace 1 in an orderly manner, and conduct preliminary guidance and screening through the material guide funnel 20 to ensure that the garbage enters the incineration bin 21 evenly, so as to prepare for the subsequent incineration treatment.

[0071] S2: In the process of introducing domestic garbage into the incineration bin 21, the total amount of garbage entering the incineration bin 21 is regulated and controlled by the regulating end 22 to avoid excessive amount of garbage to be processed in the incineration bin 21 resulting in insufficient incineration.
