Description

TECHNICAL FIELD

[0001] The utility model relates to the field of garbage treatment equipment, concretely is a domestic waste carbonization furnace. BACKGROUND

[0002] In daily life, people consume a large amount of living materials, which in turn generates kitchen waste (such as leftovers, fruit peels, etc.), recyclable materials (such as waste paper, plastic bottles, metals, etc.), hazardous waste (such as waste batteries, waste fluorescent tubes, waste mercury thermometers, etc.), and other waste (such as used paper towels, ceramic fragments, etc.).

[0003] In order to avoid the impact of domestic waste on the normal operation of society, it is usually necessary to treat domestic waste. At present, there are many ways to treat domestic waste, such as landfilling, incineration, composting, recycling, etc.

[0004] Landfilling is to transport domestic waste to a special landfill site, then spread the waste in a pre-dug landfill pit, compact it, and cover it with a layer of soil. As the accumulation of waste, the space of the landfill site is gradually filled. This treatment method occupies a large amount of land resources, and if the leachate treatment of the landfill site is not proper, it will cause serious pollution to the groundwater and soil. In addition, if the greenhouse gases (such as methane) generated after landfilling are not collected and utilized, it will exacerbate climate change.

[0005] Incineration is to transport waste to an incineration plant, first pretreat it, such as crushing, screening, etc., to ensure that the waste can burn evenly. Then, the waste is burned in an incinerator, and the high-temperature heat generated by the burning can be used for power generation or heating. This treatment method requires the construction of an incineration plant, which has a high investment cost, and if the incineration process is not properly controlled, a large amount of harmful gases and fly ash will be produced, causing serious harm to the environment and human health.

[0006] Composting is mainly aimed at organic waste such as kitchen waste, which uses microorganisms to decompose organic waste, and converts it into stable humus. First, collect the organic waste, adjust its humidity, air permeability, etc., then add appropriate microbial inoculants (such as composting bacteria), and compost at appropriate temperature and environment. After a period of fermentation (usually several weeks or months), the organic waste will become a compost product similar to soil conditioner, which can be used in agriculture, horticulture, etc. This method requires a large site, and if a large amount of impurities (such as plastic, glass, etc.) are mixed in the waste, it will affect the quality of the compost. In addition, the odor of the compost may have some impact on the surrounding environment.

[0007] The recycling treatment classifies and recycles the recyclable materials in the household garbage. The recycling process includes multiple links such as collection, classification, transportation and processing. Different types of recyclable materials are separated through garbage classification and recycling station collection of residents, and then transported to the corresponding processing plant for treatment. However, the establishment and operation of the recycling system requires a large amount of manpower, material resources and financial resources, and the recycling treatment of some mixed garbage or contaminated recyclable materials is more difficult.

[0039] The following further description is made in conjunction with the drawings and specific embodiments:

[0040] Example 1

[0041] As Figure 1 , Figure 2 , Figure 3As shown in the figure, in order to avoid environmental pollution caused by household garbage disposal, the present example provides a new household garbage disposal device, specifically a carbonization furnace. The carbonization furnace includes an upper shell 1, a lower shell 2, a stirring blade 17, etc. The central angles of the upper shell 1 and the lower shell 2 are both set to 180°, and they are connected by bolts and arranged in an upper and lower splicing manner. End plates 11 are provided at the ends of the upper shell 1 and the lower shell 2. Under the support of the end plates 11, the upper shell 1 and the lower shell 2 stably form a carbonization space. In order to carbonize the household garbage located in the upper shell 1 and the lower shell 2, mounting holes 22 are provided on the side walls of the upper shell 1 and the lower shell 2, and heating rods are inserted and arranged at the mounting holes 22. The power lines of the heating rods extend through the side walls of the shells to the outside of the space formed by the upper shell 1 and the lower shell 2, and are then connected to the power supply. Therefore, under the condition that the heating rods are powered on, the temperature of the space formed by the upper shell 1 and the lower shell 2 can be increased, providing support for the carbonization treatment of the garbage.

[0042] As shown in the figure, Figure 3 The stirring blade 17 is arranged in the space formed by the upper shell 1 and the lower shell 2, and is mounted on the central shaft. The ends of the central shaft pass through the end plates 11 and are stably mounted under the action of the bearing seat. Therefore, under the condition that the second motor 15 is working, the stirring blade 17 can be controlled to rotate, forcing the household garbage located in the upper shell 1 and the lower shell 2 to turn over, facilitating the full carbonization treatment of the garbage and improving the carbonization efficiency.

[0043] As shown in the figure, Figure 4 In order to add household garbage to be treated into the space formed by the upper shell 1 and the lower shell 2, and output the carbonized material from the space formed by the upper shell 1 and the lower shell 2, a feeding port 19 is provided on the upper shell 1, and a discharging port 21 is provided on the lower shell 2. The material can pass through the feeding port 19 and the discharging port 21 to realize the entry and exit of the material.

[0044] As shown in the figure, Figure 5 In order to block the feeding port 19 and the discharging port 21 and realize the carbonization treatment of the household garbage, a blocking assembly 4 is arranged in the space formed by the upper shell 1 and the lower shell 2. The blocking assembly 4 includes a first blocking plate 41 and a second blocking plate 42. The first blocking plate 41 and the second blocking plate 42 are respectively arranged adjacent to the discharging port 21 and the feeding port 19, and can move relative to the discharging port 21 and the feeding port 19. Therefore, the positions of the first blocking plate 41 and the second blocking plate 42 can be adjusted according to the needs, and the smoothness of the discharging port 21 and the feeding port 19 can be adjusted. This provides convenience for forming a closed space by the upper shell 1 and the lower shell 2 under the action of the first blocking plate 41 and the second blocking plate 42, and avoids the entry of external oxygen to affect the carbonization treatment.

[0045] As shown in the figure, Figure 6 , Figure 7As shown, in order to realize the first blocking plate 41 and the second blocking plate 42 movable arrangement, the end of the second blocking plate 42 is fixedly provided with a second annular plate 421, the section of the second annular plate 421 is provided with an L-shaped structure, the end of the first blocking plate 41 is fixedly provided with a first annular plate 411, the first annular plate 411 is installed on the second annular plate 421. Under the action of the annular plate, the first blocking plate 41 and the second blocking plate 42 are stably arranged in the space composed of the upper shell 1 and the lower shell 2, and the second blocking plate 42 is arranged on the inner side wall of the upper shell 1, and the first blocking plate 41 is arranged on the inner side wall of the lower shell 2, which provides support for blocking the discharge port 21 and the feeding port 19 by the blocking plate.

[0046] As shown in Figure 1 , Figure 5 in order to control the rotation of the annular plate, the inner side of the first annular plate 411 is fixedly provided with a first gear ring 412, the inner side of the second annular plate 421 is fixedly provided with a second gear ring 422, the inner side of the first gear ring 412 and the second gear ring 422 is respectively provided with a second gear 44 and a first gear 43, the center shaft of the second gear 44 and the first gear 43 penetrates the end plate 11 and is connected and installed on the side of the end plate 11 through the bearing seat, and the end of the center shaft is connected with the first motor 14, so that under the working of the first motor 14, the first gear 43 and the second gear 44 can be controlled to rotate, and then the corresponding annular plate is controlled to rotate, forcing the blocking plate to move, which provides convenience for adjusting the smoothness of the discharge port 21 and the feeding port 19.

[0047] As shown in Figure 5 , Figure 14 in order to control the rotation of the annular plate, the inner side of the first annular plate 411 is fixedly provided with a first gear ring 412, the inner side of the second annular plate 421 is fixedly provided with a second gear ring 422, the inner side of the first gear ring 412 and the second gear ring 422 is respectively provided with a second gear 44 and a first gear 43, the center shaft of the second gear 44 and the first gear 43 penetrates the end plate 11 and is connected and installed on the side of the end plate 11 through the bearing seat, and the end of the center shaft is connected with the first motor 14, so that under the working of the first motor 14, the first gear 43 and the second gear 44 can be controlled to rotate, and then the corresponding annular plate is controlled to rotate, forcing the blocking plate to move, which provides convenience for adjusting the smoothness of the discharge port 21 and the feeding port 19.

[0048] The outer diameter of the second annular plate 421 can be equal to the inner diameter of the space composed of the upper shell 1 and the lower shell 2, and the outer diameter of the first annular plate 411 can be equal to the larger inner diameter of the second annular plate 421. Under this setting, in order to reduce the relative movement friction, lubricant can be provided on the contact surface, or the contact surface can be polished and coated with a low friction coefficient coating (polytetrafluoroethylene).

[0049] The outer diameter of the second annular plate 421 can be smaller than the inner diameter of the space formed by the upper shell 1 and the lower shell 2, and the outer diameter of the first annular plate 411 can be smaller than the larger inner diameter of the second annular plate 421. In this case, bearings (such as sealing bearings) are needed to connect the adjacent shells and the second annular plate 421 and the first annular plate 411. In this case, the outer side surface of the blocking plate and the outer side wall surface of the annular plate are not arranged on the same curved surface.

[0050] As shown in Figure 2 , Figure 8 , Figure 9 shown, in order to reduce the amount of oxygen entering the space formed by the upper shell 1 and the lower shell 2 due to the input of the household garbage to be treated, a hopper 3 is provided above the feed inlet 19, a material hole 31 is provided on the hopper 3, and a closing assembly 5 is provided at the material hole 31 on the upper side of the hopper 3. When the material in the upper shell 1 and the lower shell 2 is subjected to carbonization treatment, i.e. when the feed inlet 19 is closed, the household garbage is input into the hopper 3. After the household garbage is input, the upper material hole 31 of the hopper 3 is blocked by the closing assembly 5 to prevent external oxygen from entering, and the gas in the hopper 3 is pumped out under the action of the air pump 12. When the carbonized material in the upper shell 1 and the lower shell 2 is output, the feed inlet 19 is unobstructed, and the household garbage in the hopper 3 falls into the space formed by the upper shell 1 and the lower shell 2. Since the space formed by the hopper 3, the upper shell 1 and the lower shell 2 is in a closed state, the amount of oxygen brought in by the input of the material is reduced.

[0051] As shown in Figures 11-13 , specifically, the closing assembly 5 includes a rotating shaft 53, a first closing plate 51 and a second closing plate 52. The first closing plate 51 and the second closing plate 52 are both arranged on the outer side of the hopper 3. A first connecting plate 511 is fixedly connected and arranged on the end of the first closing plate 51 through a second connecting plate 512. A first annular plate 513 is fixedly arranged on the end of the first connecting plate 511. A second annular plate 522 is fixedly arranged on the end of the second closing plate 52 through a third connecting plate 521. The first annular plate 513 is connected and sleeved on the rotating shaft 53 through a bolt. The second annular plate 522 is connected and sleeved on the rotating shaft 53 through a bearing and is arranged on the end of the first connecting plate 511 away from the first annular plate 513. The rotating shaft 53 is arranged along the length direction of the hopper 3 and is installed on the bracket 32 of the hopper 3 through a bearing seat 54. The end of the rotating shaft 53 is connected with the first motor 14. The above arrangement can drive the first annular plate 513 to rotate when the first motor 14 drives the rotating shaft 53 to rotate, thereby controlling the rotation of the first closing plate 51 and providing support for changing the unobstructed degree of the material hole 31. The motor can be a servo motor, a stepping motor or the like.

[0052] When the first closing plate 51 rotates, in order to control the second closing plate 52 to rotate in the opposite direction, driving gears 523 are provided on the side walls of the first ring plate 513 and the second ring plate 522 that are close to each other. An intermediate gear 524 is meshed between the two driving gears 523 and connected to the hopper 3. Therefore, under the action of the intermediate gear 524, power transmission can be realized and the two driving gears 523 can be controlled to rotate in the opposite direction, thereby controlling the first closing plate 51 and the second closing plate 52 to rotate in the opposite direction, and quickly adjusting the unobstructedness of the material hole 31.

[0053] Example 2

[0054] like Figure 1 As shown, based on Embodiment 1, in order to extract the gas in the hopper 3 after the closing component 5 blocks the material hole 31, the air pump 12 is installed on the side of the end plate 11, and a first air pipe 13 is provided at the input end. The first air pipe 13 is provided with two air inlets, and the two air inlets are connected to the hopper 3 and the space formed by the upper shell 1 and the lower shell 2 respectively through solenoid valves. Then, by controlling the operation of the solenoid valve, the hopper 3 can be connected to the air pump 12, and the gas in the hopper 3 can be extracted under the action of the air pump 12, thereby reducing the oxygen content in the hopper 3. The operation of the solenoid valve can also connect the space formed by the upper shell 1 and the lower shell 2 to the air pump 12, providing support for extracting the gas in the space after the domestic waste is put in and the space formed by the upper shell 1 and the lower shell 2 is closed, so as to realize carbonization treatment. In addition, the carbonized waste gas that has accumulated in the space between the upper shell 1 and the lower shell 2 can be extracted by the air pump 12 and sent to the gas purification device (a filter with a catalyst or adsorbent) to achieve the purification of the waste gas.

[0055] Example 3

[0056] like Figure 2 As shown, based on Embodiment 1 or 2, another air pump 12 can be installed on the side of the end plate 11. The air inlet of the air pump 12 is connected to the space formed by the upper shell 1 and the lower shell 2 through the second air pipe 18, and the output end is first connected to the gas purification device through the second air pipe 18, and then connected to the gas tank 16. The output end of the gas tank 16 can be connected to the space formed by the upper shell 1 and the lower shell 2 through the second air pipe 18. Therefore, when inert gas is stored in the gas tank 16, the inert gas can be circulated in and out of the space formed by the upper shell 1 and the lower shell 2 under the action of the air pump 12, thereby achieving oxygen-free or oxygen-deficient carbonization treatment. A solenoid valve is installed on the second air pipe 18. The gas purification device removes trace amounts of oxygen and other impurities from the circulating gas to further maintain an oxygen-free or oxygen-deficient environment. Specifically, it may include a cooler, a dust collector, an activated carbon adsorber, etc. Under the action of the cooler, water vapor condenses into liquid water and is discharged. Under the action of the dust collector, solid particulate matter is removed, and the activated carbon adsorber adsorbs harmful gases.

Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
