Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, specifically to a waste incineration device that ensures complete combustion. Background Technology

[0002] With the development of the rural economy and the improvement of residents' living standards, the amount of rural waste generated has been increasing year by year, including a large amount of combustible waste such as crop straw, waste plastics, and kitchen waste. Due to the imperfect waste collection and transportation system and the lack of treatment facilities in rural areas, a large amount of waste is left in the open or in simple landfills for a long time. This not only occupies arable land resources and pollutes soil and water sources, but also easily breeds mosquitoes and flies that spread diseases, posing a serious threat to the rural ecological environment and human health.

[0003] Traditional waste disposal methods, such as indiscriminate dumping and on-site incineration, suffer from problems such as incomplete combustion and severe black smoke pollution. Large-scale waste incineration plants, due to their high investment costs, large land area, and need for centralized transportation, are difficult to meet the decentralized and small-scale waste disposal needs of rural areas.

[0004] The limitations of existing rural waste incineration technology result in low combustion efficiency: most of the simple incineration devices in rural areas use open combustion or small stoves, lacking scientific oxygen supply control and combustion promotion design. As a result, waste is prone to incomplete combustion in some areas and serious heat waste. Some devices even need to rely on auxiliary fuels such as diesel to maintain combustion, which increases operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a waste incineration device that ensures complete combustion, thereby solving the problem of incomplete combustion that easily occurs in simple incineration devices in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A waste incineration device for complete combustion includes a crusher, a combustion aid storage tank, a mixer, and an incinerator. The discharge ports of the crusher and the combustion aid storage tank are connected to the inlet of the mixer. The discharge port of the mixer is connected to the inlet of the incinerator. The incinerator is provided with a combustion chamber, and a grate is horizontally arranged in the combustion chamber. An air supply pipe is horizontally arranged below the grate in the combustion chamber. A fan for supplying air to the air supply pipe is arranged on the side of the incinerator. An ash discharge port is arranged near the bottom of the incinerator.

[0007] A further technical solution includes a storage box, with a discharge section formed by a protrusion on the side of the top of the storage box. The interior of the storage box and the interior of the discharge section are connected. An outlet is provided on the lower side of the discharge section, which is connected to the feed inlet of the incinerator. The discharge outlet of the mixer is connected to the feed inlet of the storage box through a screw conveyor. A track is horizontally arranged near the top of the storage box, with one end of the track placed inside the discharge section. An electric moving seat is movably arranged on the track, and a traction machine is arranged on the lower side of the electric moving seat. An electric grab bucket is lifted and lowered on the traction machine.

[0008] A further technical solution is to seal the end of the air supply pipe away from the fan, and to have several air holes along the length of the lower side of the air supply pipe.

[0009] A further technical solution is to install an ash-blocking door at the ash discharge port and an exhaust pipe at the top of the incinerator.

[0010] A further technical solution is that a feed pipe is vertically installed at the top of the incinerator, the upper end of the feed pipe is the feed inlet of the incinerator, a rotating hole is installed near the upper end of the feed pipe that runs through the inside and outside, a rotating rod is rotatably installed in the rotating hole, a baffle is connected to the rotating rod inside the feed pipe, a counterweight is connected to the rotating rod outside the feed pipe, and a limit block is installed on the inner wall of the feed pipe above the baffle.

[0011] A further technical solution is to install a protective cover on the outer wall of the feed pipe at the position of the rotating rod to cover the rotating rod and the counterweight.

[0012] A further technical solution is to install a guide sloping plate at the lower end of the inner wall of the feed pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Figures 1 to 2 The following is an embodiment of the present invention.

[0019] Example 1: A waste incineration device for complete combustion includes a crusher 1, a combustion aid storage tank 2, a mixer 3, and an incinerator 4. The discharge ports of the crusher 1 and the combustion aid storage tank 2 are both connected to the inlet of the mixer 3. The discharge port of the mixer 3 is connected to the inlet of the incinerator 4. The incinerator 4 has a combustion chamber 5, and a grate 6 is horizontally arranged inside the combustion chamber 5. A gas supply pipe 7 is horizontally arranged below the grate 6 in the combustion chamber 5. A blower 8 for supplying gas to the gas supply pipe 7 is arranged on the side of the incinerator 4. An ash discharge port 9 is located near the bottom of the incinerator 4. Before the waste enters the incinerator 4, it is crushed by the crusher 1, making the waste more easily combusted. The mixer 3 mixes the waste and the combustion aid, ensuring more complete and thorough combustion of the waste in the incinerator 4. By installing the air supply pipe 7 and the blower 8, sufficient oxygen is provided in the incinerator 4 to meet the needs of waste incineration, ensuring complete combustion. The ash discharge port 9 collects the ash produced after combustion, which can be used as waste material. The shredder 1 uses conventional blade or gear shredders to break large pieces of waste into smaller pieces. The combustion aid storage tank 2 stores different types of combustion aids as needed, and then supplies them to the mixer 3 via a feed pipe, mixing them with the waste in a specific ratio. The mixer 3, with its high-speed rotating propeller blades, ensures thorough mixing of the waste and combustion aids. An igniter is installed on the wall of the incineration chamber 5 to ignite the waste.

[0020] The system also includes a storage tank 10, with a discharge section 11 formed by a protrusion on the side of the top of the storage tank 10. The interior of the storage tank 10 is connected to the interior of the discharge section 11. A discharge outlet 12 is provided on the lower side of the discharge section 11, and the discharge outlet 12 is connected to the feed inlet of the incinerator 4. The discharge outlet of the mixer 3 is connected to the feed inlet of the storage tank 10 via a screw conveyor 13. A track 14 is horizontally arranged near the top of the storage tank 10, with one end of the track 14 placed inside the discharge section 11. An electric moving seat 15 is movably arranged on the track 14, and a traction machine 16 is arranged on the lower side of the electric moving seat 15. An electric grab bucket 17 is raised and lowered on the traction machine 16. By setting up the storage tank, the mixed waste can be stored for a short period of time. When the waste accumulates to a certain amount, the electric grab bucket 17 grabs the waste to the position of the discharge outlet 12, and then drops it into the feed inlet of the incinerator 4 through the discharge outlet 12 for incineration in the incinerator 4. Through the cooperation of track 14, electric moving seat 15 and traction machine 16, the electric grab bucket 17 can periodically grab garbage into the incinerator 4 for incineration. The electric grab bucket 17 is generally equipped with a counterweight so that when the electric grab bucket 17 is inserted into the garbage, it can be inserted to a certain depth, thereby grabbing enough garbage.

[0021] The end of the air supply pipe 7 away from the fan 8 is sealed, and several air holes are provided along the length of the lower side of the air supply pipe 7. The arrangement of the air holes allows air to be evenly delivered from below the grate 6 upwards, ensuring that the burning waste can obtain sufficient oxygen and preventing the air holes from being blocked by ash.

[0022] An ash-blocking door is installed at the ash discharge port 9, and an exhaust pipe 18 is installed at the top of the incinerator 4. The ash-blocking door prevents the ash from being carried out of the ash discharge port 9 during waste incineration. The exhaust pipe 18 allows the exhaust gas to be discharged. Furthermore, to effectively utilize this high-temperature flue gas, heat exchangers can be connected to heat domestic or industrial water, achieving heat recovery.

[0023] A feed pipe 19 is vertically installed at the top of the incinerator 4. The upper end of the feed pipe 19 is the inlet of the incinerator 4. Near the upper end of the feed pipe 19, there is a through-hole 20. A rotating rod 21 is rotatably installed inside the rotating hole 20. A baffle 22 is connected to the rotating rod 21 inside the feed pipe 19. A counterweight 23 is connected to the rotating rod 21 outside the feed pipe 19. A limit block 24 is installed on the inner wall of the feed pipe 19 above the baffle 22. When no waste is being fed into the incinerator 4, the baffle 22 is in a horizontal position with the cooperation of the counterweight 23 and the limit block 24, sealing the upper end of the feed pipe 19, thus preventing flames from spreading into the storage tank 10. When garbage is disposed of, it falls onto the baffle 22. Due to gravity, the baffle 22 is pressed downwards, causing the rotating rod 21 to rotate around the rotating shaft 27 inside the rotating hole 20. This tilts the baffle 22 downwards, allowing the garbage to fall into the incinerator 4. After the garbage falls, the counterweight 23 returns the baffle 22 to a horizontal position. The feed pipe 19 is equipped with a protective inclined plate above the rotating hole 20 to prevent garbage from entering the rotating hole 20 during its fall.

[0024] The outer wall of the feed pipe 19 is provided with a protective cover 25 at the position of the rotating rod 21 to cover the rotating rod 21 and the counterweight 23. By providing the protective cover 25, the flue gas from the combustion of the incinerator 4 can be prevented from being discharged from the rotating hole 20.

[0025] A guide plate 26 is provided at the lower end of the inner wall of the feed pipe 19. By providing the guide plate 26, when the garbage falls onto the upper side of the grate 6, it can be piled up towards the middle of the upper side of the grate 6, so that it can be evenly distributed to the surrounding area, making the combustion more complete.

[0026] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
