Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to an incineration device for reducing the volume and amount of urban waste. Background Technology

[0002] Urban waste refers to

[0003] A large amount of urban waste is generated in daily urban life or in activities that provide services for daily urban life. With the development of urbanization, the amount of urban waste is increasing. At present, urban waste mainly includes residential waste, commercial waste, market waste, street waste, public place waste, and waste from government agencies, schools, factories and mines. It is characterized by complex composition and high content of inorganic substances. In order to prevent urban waste from causing environmental pollution, spreading diseases and affecting the appearance of the city, centralized treatment of urban waste is very necessary.

[0004] Currently, the main methods for urban waste disposal include landfill, composting, incineration, and recycling. Among these, landfill, composting, and recycling methods suffer from drawbacks such as large waste volumes and large land occupation. Incineration, which reduces waste volume and generates heat, is widely used. However, traditional waste incineration typically involves mixing waste with fuel and igniting it. During the incineration process, the carbon dioxide and other flue gases produced by waste combustion can obstruct air contact with the waste, leading to incomplete combustion. Therefore, this application provides an urban waste volume reduction incineration device to meet this need. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an incineration device for reducing the volume and amount of urban waste in order to solve the problem that existing waste incineration is not thorough enough.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A municipal waste volume reduction incineration device includes an incinerator. A waste feeding bin door is provided at the middle of the side wall of the incinerator. A pair of slide rails are horizontally fixed on the side wall of the incinerator and extend into the incinerator. A waste feeding hopper is slidably mounted on the slide rails. The bottom of the waste feeding hopper is hollowed out and the waste feeding hopper can slide along the pair of slide rails through the waste feeding bin door and enter the incinerator.

[0008] Optionally, a fuel injection chamber door is provided at the bottom of the incinerator, and a first mesh support plate is horizontally fixed inside the incinerator, with the first mesh support plate located below the fuel injection chamber door.

[0009] Optionally, an ash removal chamber door is also provided at the bottom of the side wall of the incinerator, and the ash removal chamber door is located below the first mesh support plate.

[0010] Optionally, a ventilation pipe is provided on the side wall of the incinerator, and the ventilation pipe is located below the first mesh support plate.

[0011] Optionally, a support column is vertically fixed at the bottom of the end of the slide rail away from the incinerator, and the bottom end of the support column is flush with the bottom end of the incinerator.

[0012] Optionally, the waste feeding hopper includes a second mesh support plate slidably mounted on a pair of slide rails and a surrounding plate fixed on the second mesh support plate, wherein a pull ring is provided on the side wall of the surrounding plate away from the incinerator.

[0013] Optionally, the upper surface of the slide rail is provided with a rail groove along the length direction, and the bottom of the second mesh support plate is provided with a protrusion that slides and engages with the rail groove.

[0014] Optionally, a recovery tray is provided between the bottom end of the support column and the incinerator, and a drain pipe is provided through the bottom of the side wall of the recovery tray.

[0015] Optionally, the top of the incinerator is connected to a flue pipe, the top of the flue pipe is bent horizontally to one side and connected to a flue gas purification box, the flue gas purification box has through holes at both ends, and multiple filter plates are installed inside the flue gas purification box.

[0016] Optionally, the bottom wall of the flue gas purification box is provided with a through groove that allows the filter plate to pass through, and the bottom of the flue gas purification box is equipped with a cover plate for sealing the through groove.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting up a garbage feeding hopper, urban garbage is put into the garbage feeding hopper. The hollow structure at the bottom of the garbage feeding hopper allows residual liquid in the garbage to seep into the recycling tray for collection, and then be centrally discharged and treated by the drain pipe, which is conducive to the incineration of garbage. The garbage hopper, filled with waste, is pushed into the incinerator along a slide rail. Fuel is then added and ignited through the fuel injection door onto the first mesh tray inside the incinerator. The flame generated by the combustion of fuel on the first mesh tray directly burns the waste inside the hopper through the perforated bottom. This suspended combustion structure allows the waste to fully contact the air and the flame. Compared to the method of mixing waste and fuel together for combustion, the outer flame of the fuel combustion burns the waste with higher heat, resulting in more efficient combustion. In addition, it avoids the phenomenon of incomplete combustion caused by carbon dioxide and other flue gas from the waste blocking the air from contacting the waste, thus making the waste combustion more thorough and efficient. After the waste is incinerated, the ash residue falls through the first mesh tray to the bottom of the incinerator and can be cleaned through the ash removal door. The flue gas is discharged from the top of the incinerator through the exhaust pipe. The filter plate in the flue gas purification box can filter and purify the flue gas, reducing the pollution of air by particulate matter in the flue gas. Attached Figure Description

[0033] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a municipal waste volume reduction incineration device, including an incinerator 1. A waste feeding hopper door 2 is provided at the middle of the side wall of the incinerator 1. A pair of slide rails 5 are horizontally fixed on the side wall of the incinerator 1, extending into the incinerator 1. A waste feeding hopper 6 is slidably mounted on the slide rails 5. The bottom of the waste feeding hopper 6 is hollow, and the waste feeding hopper 6 can slide along the pair of slide rails 5 through the waste feeding hopper door 2 and enter the incinerator 1. A fuel feeding hopper door 3 is provided at the bottom of the incinerator 1. A first mesh support plate 12 is horizontally fixed inside the fuel feeding hopper door 3 of the incinerator 1. The first mesh support plate 12 is located below the fuel feeding hopper door 3. Municipal waste is fed into the waste feeding hopper 6. The hollow structure at the bottom of the waste feeding hopper 6 allows residual liquid in the waste to seep into the waste. The open bottom of the waste feeding hopper 6, which is conducive to the incineration of waste, is pushed into the incinerator 1 along the slide rail 5. Fuel is added and ignited through the fuel feeding door 3 onto the first mesh support plate 12 inside the incinerator 1. The flame generated by the combustion of fuel on the first mesh support plate 12 can directly burn the waste in the waste feeding hopper 6 through the open bottom. This suspended structure for waste incineration allows the waste to fully contact the air and the flame. Compared with the method of mixing waste and fuel together for incineration, the outer flame of the fuel combustion burns the waste with higher heat and is more efficient. In addition, it avoids the phenomenon of incomplete combustion of waste caused by carbon dioxide and other flue gas produced by waste incineration blocking the air from contacting the waste, thus making the incineration of waste more thorough and efficient.

[0034] like Figure 1 and Figure 2As shown, an ash removal chamber door 4 is also provided at the bottom of the side wall of the incinerator 1. The ash removal chamber door 4 is located below the first mesh support plate 12. After the waste is incinerated, the ash produced falls into the bottom of the incinerator 1 through the first mesh support plate 12 and can be cleaned through the ash removal chamber door 4. A ventilation pipe 22 is installed on the side wall of the incinerator 1. The ventilation pipe 22 is located below the first mesh support plate 12 and is used to supply air into the incinerator 1 to ensure that there is sufficient oxygen for fuel and waste combustion. A support column 7 is vertically fixed at the bottom of the end of the slide rail 5 away from the incinerator 1. The bottom end of the support column 7 is flush with the bottom end of the incinerator 1 and is used to support the slide rail 5. A recovery tray 8 is provided between the bottom end of the support column 7 and the incinerator 1. A drain pipe 9 is installed at the bottom of the side wall of the recovery tray 8. The residual liquid in the waste seeps through the hollow structure at the bottom of the waste feeding hopper 6 and falls into the recovery tray 8 for collection. It can be discharged and treated centrally by the drain pipe 9.

[0035] like Figures 1 to 4 As shown, the waste feeding hopper 6 includes a second mesh support plate 14 slidably mounted on a pair of slide rails 5 and a surrounding plate 13 fixed on the second mesh support plate 14. A pull ring 15 is provided on the side wall of the surrounding plate 13 away from the incinerator 1. A rail groove 16 is opened on the upper surface of the slide rail 5 along the length direction. A protrusion 17 is provided at the bottom of the second mesh support plate 14 that slides and engages with the rail groove 16.

[0036] like Figure 1 and Figure 5 The top of the incinerator 1 is connected to a flue pipe 10. The top of the flue pipe 10 is bent horizontally to one side and connected to a flue gas purification box 11. The flue gas purification box 11 has through holes 18 at both ends. Multiple filter plates 19 are installed inside the flue gas purification box 11. After the waste is incinerated, the flue gas is discharged from the top of the incinerator 1 through the flue pipe 10. The filter plates 19 in the flue gas purification box 11 can filter and purify the flue gas, reducing the pollution of air by particulate matter in the flue gas. A through groove 20 is opened on the bottom wall of the flue gas purification box 11 to allow the filter plates 19 to pass through. The bottom of the flue gas purification box 11 is equipped with a cover plate 21 for sealing the through groove 20, which facilitates the replacement and cleaning of the filter plates 19.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] In use, municipal waste is placed into the waste feeding hopper 6. The perforated structure at the bottom of the waste feeding hopper 6 allows residual liquid in the waste to seep into the collection tray 8 for collection and centralized discharge through the drain pipe 9. The waste feeding hopper door 2 is opened to push the waste-filled waste feeding hopper 6 along the slide rail 5 into the incinerator 1. The waste feeding hopper door 2 is closed, and fuel is added and ignited through the fuel feeding hopper door 3 onto the first mesh tray 12 inside the incinerator 1. The flame generated by the fuel burning on the first mesh tray 12 can directly burn the waste in the waste feeding hopper 6 through the perforated bottom of the waste feeding hopper 6. This suspended waste incineration structure allows the waste to be burned more efficiently. Compared to the method of mixing garbage and fuel together for incineration, the outer flame of the fuel combustion provides higher heat and more efficient combustion of garbage. In addition, it avoids the phenomenon of incomplete combustion of garbage caused by carbon dioxide and other flue gas produced by garbage incineration blocking the air from contacting the garbage. As a result, the garbage is burned more thoroughly and efficiently. After the garbage is burned, the ash residue falls into the bottom of the incinerator 1 through the first mesh tray 12 and can be cleaned through the ash cleaning chamber door 4. The flue gas is discharged from the top of the incinerator 1 through the exhaust pipe 10. The filter plate 19 in the flue gas purification box 11 can filter and purify the flue gas, reducing the pollution of air by particulate matter in the flue gas.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
