[0011] 1. This utility model fixes the incinerator rack inside the incinerator cavity by pushing it in, and then rotating the fasteners to change the friction between the third fixing tube and the long shaft. This allows for adjustment of the spacing and pitch angle between the lifting shafts, making it adaptable to different types of waste. For example, the spacing between the lifting shafts can be adjusted according to the volume of the waste, resulting in three layers. The spacing between the lifting shafts in the upper layer is larger, the middle layer is smaller, and the lower layer is even smaller. This divides the waste into three layers, with space between each layer, allowing both the top and bottom surfaces of the waste to come into contact with oxygen and flames for combustion. After the waste in the upper layer burns and shrinks in volume, it falls between the lifting shafts in the middle layer and continues to burn suspended in the air. Similarly, after burning and shrinking in volume, the waste falls between the lifting shafts in the lower layer and continues to burn suspended in the air. The burning ash does not accumulate on the surface of the unburned waste, making combustion fast and efficient.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste incineration technology, specifically an auxiliary combustion rack for a waste incinerator. Background Technology
[0002] An incinerator, also known as a waste incinerator, is an industrial device used to process solid waste. It achieves waste reduction and energy recovery through high-temperature combustion. Its main types include grate type and fluidized bed technology, equipped with exhaust gas purification systems to remove pollutants such as dioxins, and utilize waste heat to generate electricity.
[0003] Chinese utility model patent CN205402736U, published on July 27, 2016, discloses a waste incinerator, including a furnace body, a furnace chamber, and grate bars. The grate bars are located in the lower middle part of the furnace body and are arranged in a frustum shape with a higher center and lower periphery. The furnace chamber is located below the grate bars and is equipped with a flame-throwing device. The flame-throwing device is equipped with a fire supply pipe for connecting to an external combustion device and an external return gas pipe. A gas exhaust pipe for venting the combustion gases is located below the grate bars. A gas collecting device is located above the grate bars and is connected to the external return gas pipe. The return gas pipe is equipped with an induced draft fan for forced gas circulation, and a water collecting device is located at the bottom of the return gas pipe. This waste incinerator has a simple structure, low equipment investment, fully utilizes energy, has high thermal efficiency, complete combustion, and incinerates various types of waste together. The waste incineration operation is simple.
[0004] However, the aforementioned publicly disclosed solutions have the following shortcomings: the overhead auxiliary combustion support used in existing waste incinerators cannot uniformly support the waste and create enough space for airflow and sufficient oxygen for combustion, which makes it impossible to further improve the combustion efficiency when a large amount of waste is piled up. Utility Model Content
[0005] The purpose of this invention is to solve the technical problem that the auxiliary combustion support for overhead waste used in existing waste incinerators cannot achieve uniform support of waste and form enough space for air flow and sufficient oxygen for combustion reaction, thus preventing further improvement in combustion efficiency when a large amount of waste is piled up. The invention provides an auxiliary combustion support for waste incinerators.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] The auxiliary combustion frame for a waste incinerator according to this utility model includes two parallel long shafts; multiple first fixed tubes are sleeved on the long shafts; short tubes are fixedly connected between the first fixed tubes; multiple third fixed tubes are sleeved on the long shafts; a cantilever shaft is vertically fixed to the outer surface of the third fixed tubes; and fasteners are threadedly connected to the third fixed tubes corresponding to the holes on the long shafts.
[0008] Furthermore, a plurality of second fixing tubes are sleeved on the long shaft; and a reinforcing support tube is fixedly connected between the second fixing tubes.
[0009] Furthermore, the end of the lifting shaft is provided with a semi-circular chamfer.
[0010] The auxiliary combustion rack for a waste incinerator provided by this utility model has the following beneficial effects:
[0011] 1. This utility model fixes the incinerator rack inside the incinerator cavity by pushing it in, and then rotating the fasteners to change the friction between the third fixing tube and the long shaft. This allows for adjustment of the spacing and pitch angle between the lifting shafts, making it adaptable to different types of waste. For example, the spacing between the lifting shafts can be adjusted according to the volume of the waste, resulting in three layers. The spacing between the lifting shafts in the upper layer is larger, the middle layer is smaller, and the lower layer is even smaller. This divides the waste into three layers, with space between each layer, allowing both the top and bottom surfaces of the waste to come into contact with oxygen and flames for combustion. After the waste in the upper layer burns and shrinks in volume, it falls between the lifting shafts in the middle layer and continues to burn suspended in the air. Similarly, after burning and shrinking in volume, the waste falls between the lifting shafts in the lower layer and continues to burn suspended in the air. The burning ash does not accumulate on the surface of the unburned waste, making combustion fast and efficient.
[0012] 2. This utility model uses multiple second fixed tubes in conjunction with multiple reinforcing support tubes to support multiple layers of long shafts within the second fixed tubes. This allows it to be adapted to the size of the incinerator cavity, making it suitable for incinerators of different sizes. It also prevents waste from accumulating in the incinerator, which would reduce the combustion area with oxygen and flame, allowing for more efficient incineration of the same volume of waste.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.
[0021] Please see Figure 1-3 As shown, an auxiliary combustion frame for a waste incinerator includes two parallel long shafts 1; multiple first fixed tubes 2 are sleeved on the long shafts 1; short tubes 3 are fixedly connected between the first fixed tubes 2; multiple third fixed tubes 7 are sleeved on the long shafts 1; a lifting shaft 8 is vertically fixed to the outer surface of the third fixed tube 7; fasteners 9 are threadedly connected to the third fixed tubes 7 corresponding to the openings of the long shafts 1. By pushing the combustion frame into the cavity inside the incinerator and fixing it, and then rotating the fasteners 9 to change the friction between the third fixed tubes 7 and the long shafts 1, the spacing and pitch angle between the lifting shafts 8 can be adjusted to adapt to different types of waste. For example, the spacing between the lifting shafts 8 can be adjusted according to the volume of the waste to make it fit into three layers. The spacing between the lifting shafts 8 in the upper layer is larger, the middle layer is smaller, and the lower layer is even smaller. This divides the waste into three layers, with space between each layer, so that both the top and bottom surfaces of the waste can come into contact with oxygen and flames for combustion. After the waste in the upper layer burns and shrinks in volume, it falls into the middle layer and continues to burn suspended between the lifting shafts 8. After burning and shrinking in volume, it falls into the lower layer and continues to burn suspended between the lifting shafts 8. The ash from the combustion will not accumulate on the surface of the unburned waste and obstruct combustion, making combustion fast and efficient.
[0022] Multiple second fixed tubes 5 are sleeved on the long shaft 1; reinforcing support tubes 6 are fixed between the second fixed tubes 5. Through the cooperation of multiple second fixed tubes 5 and multiple reinforcing support tubes 6, the long shaft 1 with multiple layers can be supported in the second fixed tubes 5. This allows it to be adapted to the size of the incinerator cavity, making it suitable for incinerators of different sizes. It also prevents the accumulation of waste in the incinerator, which would result in a small combustion area with oxygen and flame, allowing the same volume of waste to be incinerated more efficiently.
[0023] The end of the cantilever shaft 8 is provided with a semi-circular chamfer 10. The semi-circular chamfer 10 allows the two cantilever shafts 8 to pass through each other tangentially without interfering with each other when they are aligned, so that pipes can be installed for horizontal support.
[0024] The end of the lifting shaft 8 is provided with a rope hole 11. A metal rope is connected through the rope hole 11, which can more securely fix the position of multiple lifting shafts 8, so that more garbage can be supported and kept suspended. Gaps are created between each layer of garbage, so that the flame and air can move quickly and fully surround the garbage to burn it.
[0025] A rolling tube 4 is rotatably connected to the short tube 3. The first fixed tube 2, the second fixed tube 5, and the third fixed tube 7 are lifted and kept suspended by the rolling tube 4 touching the ground. This allows the position of the first fixed tube 2, the second fixed tube 5, and the third fixed tube 7 on the long axis 1 to be adjusted and adapted according to the shape and length of the incinerator. This allows the combustion rack to maximize the support of the waste in the cavity of the incinerator and form an air flow channel, so that the waste can fully contact the flame for efficient and rapid combustion.
[0026] The diameter of the rolling tube 4 is larger than that of the first fixed tube 2, so that when the rolling tube 4 touches the ground, the first fixed tube 2, the second fixed tube 5 and the third fixed tube 7 remain suspended. This allows the positions of the first fixed tube 2, the second fixed tube 5 and the third fixed tube 7 on the long axis 1 to be adjusted and adapted according to the shape and length of the incinerator. This allows the combustion rack to cooperate with the cavity of the incinerator to maximize the support of the waste and form an air flow channel, so that the waste can fully contact the flame for efficient and rapid combustion.
