Description

Technical Field

[0001] The invention relates to an intelligent domestic garbage disposal cubicle, belonging to the technical field of garbage disposal. Background Art

[0002] Municipal domestic waste is a large amount of solid waste. With the development of my country's economy and society and the increasing requirements for environmental quality, the amount of domestic waste is increasing. At present, the mainstream treatment methods of domestic waste are sanitary landfill and incineration power generation. Sanitary landfill can achieve safe and harmless disposal. Domestic waste incinerator is a device for incinerating domestic waste. The equipment has a furnace for incineration, which is converted into waste gas and enters the secondary combustion chamber. It generally has automatic processing procedures such as automatic feeding, screening, drying, incineration, return, and dust removal. It uses high-temperature combustion to treat garbage. During the high-temperature combustion process, it will produce harmful substances such as nitrogen oxides, smoke particles, and dioxins. Direct discharge into the atmosphere will affect air quality, cause haze weather, and affect human normal life.

[0003] Traditional incinerators use manual labor to remove dust and ash after garbage combustion, which leads to heavy labor and low efficiency for operators. At the same time, manual slag cleaning has blind spots, which can easily lead to incomplete cleaning of local areas, causing dust accumulation and affecting the incineration effect.

[0004] Therefore, we have made improvements to this and proposed an intelligent domestic waste disposal warehouse. Summary of the Invention

[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] like Figure 1-Figure 7 As shown, this embodiment proposes an intelligent domestic waste treatment square warehouse, including a square warehouse body 1, a waste incinerator 3 and a flue gas purification device 5. A warehouse door 2 is installed at the bottom of the square warehouse body 1, and the waste incinerator 3 and the flue gas purification device 5 are both installed inside the cavity of the square warehouse body 1. The waste incinerator 3 includes a furnace body 31, a smoke outlet 33, and an ignition device 36. A slag outlet 34 is provided on the outer side of the bottom of the furnace body 31. A wavy first partition 311 and a second partition 312 are installed inside the furnace body 31, and the concave positions of the wavy first partition 311 and the second partition 312 are arranged opposite to the slag outlet 34; the outer end of the smoke outlet 33 is connected to a blower 4, and is connected to the flue gas purification device 5 through the blower 4.

[0031] The warehouse door 2 includes a thermal insulation coating 21, and the middle of the internal insulation coating 21 is filled with an insulation board 22, and the middle of the insulation board 22 is sleeved with a heat-conducting metal 23. The warehouse door 2 and the square warehouse body 1 are protected and supported by the same material, and the thermal insulation coating 21 provides thermal insulation protection for the outward side of the square warehouse body 1 and the warehouse door 2 to prevent the heat from the garbage incinerator 3 and the flue gas purification device 5 from radiating outward and making the environment unsuitable for humans. The insulation board 22 and the heat-conducting metal 23 collect and conduct the heat radiated from the garbage incinerator 3 and the flue gas purification device 5, and utilize the energy through the thermal power generation device connected to the outer end of the heat-conducting metal 23, so as to facilitate the conversion of heat into electrical energy and make full use of energy.

[0032] The square warehouse body 1 and the warehouse door 2 are both stepped, narrow at the top and wide at the bottom, and are connected by hinges. The bottom protective layer of the square warehouse body 1 and the warehouse door 2 is relatively thick to prevent pedestrians or workers from accidentally touching the bottom side of the device and causing heat damage during walking and working, thereby ensuring the safety of the device.

[0033] A feed port 32 is installed at the upper end of the furnace body 31, a ventilation pipe 38 is installed at the lower end of the interior of the furnace body 31, and a smoke damper 39 is fixedly installed inside the furnace body 31. The smoke damper 39 is installed in a ring shape with an inclined downward direction. A connecting cover 310 is provided above the middle part of the smoke damper 39, and a smoke outlet 33 is installed on the lower side of the smoke damper 39. A flange is provided on the outer side of the smoke outlet 33. The smoke damper 39 is installed above the smoke outlet 33 to intercept the smoke inside the furnace body 31 and guide it to the inside of the smoke outlet 33 for discharge through the smoke outlet 33, which facilitates the positive guidance of the smoke, prevents the smoke from escaping, and protects the environment.

[0034] The connecting cover 310 includes a conical cover 3101 and a rotating shaft 3103, and the conical cover 3101 is an umbrella-shaped support installed below the feed port 32, and the diameter of the conical cover 3101 is larger than the diameter of the feed port 32 and larger than the inner diameter of the smoke baffle 39, and the conical cover 3101 is rotatably installed on the top of the ventilation pipe 38 through the rotating shaft 3103, and the inner wall of the conical cover 3101 is installed with spiral fan blades 3102, and the outer side of the rotating shaft 3103 is connected to the stirring rod 3104. The installation of the connecting cover 310 facilitates full utilization of the hot air and airflow inside the furnace body 31, and the connecting cover 310 is rotated by the fan blades 3102, driving the stirring rod 3104 to stir the garbage inside the furnace body 31 and clean the surface of the ventilation pipe 38, so as to facilitate the full combustion of the garbage.

[0035] The ventilation pipe 38 is a conical cylindrical shape installed at the lower part of the interior of the furnace body 31, and a number of ventilation holes are opened on the side wall of the ventilation pipe 38. The bottom of the ventilation pipe 38 is connected to the ignition device 36, and the middle of the ignition device 36 is opened with a ventilation hole 37. The bottom of the ignition device 36 is connected to the fuel tank 35. The ventilation pipe 38 is installed at the bottom of the furnace body 31 and is connected to the ventilation hole 37 to transport air to the interior of the furnace body 31. The ventilation pipe 38 increases the contact area between the garbage and the air, which facilitates the full combustion of the garbage and improves the combustion efficiency.

[0036] Both the first partition plate 311 and the second partition plate 312 are provided with sieve holes, and the diameter of the sieve holes of the first partition plate 311 is larger than the diameter of the sieve holes of the second partition plate 312. The installation of the first partition plate 311 and the second partition plate 312 facilitates the support and filtration of the ash after combustion inside the furnace body 31, and facilitates the cleaning of the ash. The wavy setting of the first partition plate 311 and the second partition plate 312 facilitates the accumulation of the ash, and facilitates the accumulation of the ash at the inner end of the slag outlet 34, so that the ash can be fully cleaned once the slag outlet 34 is opened, thereby avoiding the influence of ash residue on the combustion effect.

[0037] The flue gas purification device 5 includes a heat dissipation shell 51, which is connected to a smoke inlet pipe 53 in the middle of the heat dissipation shell 51 and the blower 4, and a sedimentation treatment tank 52 is provided at the lower part of the heat dissipation shell 51. A baffle is installed above the sedimentation treatment tank 52, and a filter drying tube 54 is connected above the baffle. The upper end of the filter drying tube 54 is connected to an exhaust pipe 56, and a filter disc 55 is sleeved inside the filter drying tube 54. The filter drying tube 54 is sleeved above the sedimentation treatment tank 52 to filter and adsorb the flue gas after sedimentation treatment in the sedimentation treatment tank 52, thereby improving the purification effect of the flue gas, and then uniformly discharging it to facilitate sufficient treatment of the flue gas.

[0038] Specifically, when the intelligent domestic waste treatment square warehouse is in use: the square warehouse is connected as a whole to the garbage continuous feeding and drying device, and the garbage is crushed and dried by the continuous feeding and drying device, so that the garbage is pre-processed before incineration, and the garbage is continuously fed, and the crushed garbage is sent into the interior of the furnace body 31 through the feed port 32 for incineration, and during the incineration process, the fuel inside the fuel tank 35 is ignited by the ignition device 36 to provide fuel energy, and then ignited at the bottom of the furnace body 31 by the ignition device 36, and with the assistance of the air inside the ventilation hole 37, the garbage is burned. The garbage inside the furnace body 31 is incinerated, and the ventilation pipe 38 is provided to supplement oxygen for the garbage inside the furnace body 31 to avoid incomplete combustion caused by garbage accumulation. During the incineration process, hot air inside the furnace body 31 surges up and forms a vortex airflow at the top of the furnace body 31. The connecting cover 310 uses the vortex airflow to drive the connecting cover 310 to rotate. During the rotation, the stirring rod 3104 is driven to stir the garbage inside the furnace body 31 to avoid ash clogging the air outlet of the ventilation pipe 38. The conical shell of the conical cover 3101 is installed below the feed port 32 to cast on the feed port 32. The garbage entering is diverted and is put into the interior of the furnace body 31 under the guidance of the smoke baffle 39, so that the garbage is evenly distributed around the interior of the furnace body 31. The installation of the connecting cover 310 also prevents the flame and hot flue gas inside the furnace body 31 from escaping vertically upward, protecting the top of the feed port 32. The smoke baffle 39 is installed above the smoke outlet 33 to guide the flue gas to the inside of the smoke outlet 33 and send it for purification. During the combustion process of the garbage inside the furnace body 31, the dust is supported and placed by the first baffle 311 and the second baffle 312, and the first baffle 311 and the second baffle 312 are installed on the top of the smoke outlet 33. 2 are both wavy folded plates, and the bottom edge of the folded plate corresponds to the position of the slag outlet 34, so that dust inside the furnace body 31 accumulates in the grooves of the first partition 311 and the second partition 312. In this way, the processed dust is easy to handle. When cleaning the dust and slag, the slag outlet 34 on the circumferential surface of the furnace body 31 is opened, facing the concave positions of the first partition 311 and the second partition 312, and the ash and slag accumulated in the concave positions are shoveled out. The ash and slag on the protruding positions of the first partition 311 and the second partition 312 will also automatically slide down, making it easier to clean the slag and avoiding dust dead corners.

[0039] The flue gas generated by the combustion inside the furnace body 31 is discharged into the interior of the blower 4 through the slag outlet 34, and is then sent into the interior of the flue gas purification device 5 through the blower 4. A sedimentation tank is provided at the bottom of the heat dissipation shell 51 to adsorb dust, impurities and soluble harmful substances in the flue gas. The flue gas is dehumidified and filtered inside the filter drying tube 54 and filter disc 55 at the upper end of the heat dissipation shell 51 before being discharged.

[0040] A square warehouse body 1 and a warehouse door 2 are installed on the outside of the waste incinerator 3 and the flue gas purification device 5, and the square warehouse body 1 and the warehouse door 2 are both arranged in a sandwich configuration. A heat insulation coating 21, a heat insulation board 22 and a heat conductive metal 23 are arranged inside the square warehouse body 1 and the warehouse door 2. The heat conductive metal 23 is inserted into the inside of the heat insulation board 22, and the heat insulation coating 21 insulates the outer side of the heat insulation board 22 to prevent the square warehouse body 1 and the warehouse door 2 from being overheated and affecting the surrounding environment and causing harm to people. The heat conductive metal 23 is connected to an external thermal power generation device to make full use of the heat emitted during the treatment process of the waste incinerator 3 and the flue gas purification device 5, which is convenient for energy utilization.

[0041] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be encompassed by the scope of the claims of the present invention.
