Description

Technical Field

[0001] This utility model relates to the field of incinerator equipment, and in particular to an oil-free combustion device for incinerators. Background Technology

[0002] A crematorium (or incinerator) is a device specifically designed for the high-temperature incineration of human or animal remains, converting them into ashes and gas. It is widely used in the funeral industry (crematoriums), medical waste disposal, and animal necrosis treatment. Through high-temperature incineration (typically 800-1200℃), organic matter, pathogens, and harmful substances in the remains are thoroughly decomposed. The inorganic residue (ashes) after incineration can be preserved or used for burial. Modern incinerators are equipped with exhaust gas treatment systems to reduce emissions of pollutants such as dioxins, sulfur oxides, and nitrogen oxides. A crematorium is a complex device combining high-temperature combustion technology, environmental engineering, and automated control; its design must balance efficiency, environmental protection, and humanistic care. Modern incinerators, through multiple exhaust gas purification and energy recovery technologies, have become a safe and sustainable solution for the disposal of remains.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional incinerators' fuel oil ignition equipment not only emits large amounts of pollutants, but also has a complex and cumbersome installation method, making it difficult to disassemble the igniter once maintenance is needed. Utility Model Content

[0005] The main objective of this invention is to provide an oil-free combustion device for incinerators, effectively solving the problems mentioned in the background art, such as the large emissions and severe pollution of existing traditional fuel oil ignition equipment, the complex and cumbersome installation of the igniter, and the difficulty in disassembling the igniter once maintenance is required. This invention uses a parallel design of multiple gas cylinders, with natural gas as the fuel supply for the igniter, and a gas filter helps to remove impurities from the gas, thus greatly reducing carbon emissions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An oil-free combustion device for an incinerator, comprising:

[0008] Incinerator;

[0009] The main incineration chamber is located inside the incinerator;

[0010] Gas cylinders, wherein multiple gas cylinders are provided, and the multiple gas cylinders are connected in parallel to a gas filter through gas collecting pipes;

[0011] The gas filter is located at the top of the gas cylinder;

[0012] A blower is fixedly installed on one side of the incinerator, and the air inlet of the blower is connected to the gas filter through a pipe.

[0013] The igniter has an air outlet connected to the gas inlet of the blower and an outlet of the igniter's nozzle extending into the main incineration chamber.

[0014] A detachable fixing mechanism is installed on one side of the main incineration chamber. The detachable fixing mechanism clamps and fixes the igniter. The detachable fixing mechanism includes a first clamping member, a second clamping member, a rotating shaft, a fixing frame, and a locking rod. The first clamping member and the second clamping member are arranged parallel to each other. The igniter is clamped between the first clamping member and the second clamping member. The second clamping member is movably connected to the locking rod through the rotating shaft. The turning end of the rotating shaft is movably connected to one side of the fixing member. The locking rod drives the rotating shaft to rotate by vertical displacement, so as to realize the clamping or separation of the second clamping member and the first clamping member.

[0015] The fixing frame further includes:

[0016] The first extension end is located below the second clamping member and extends obliquely.

[0017] The second extension end is located on one side of the first extension end, and the angle between the second extension end and the first extension end is an obtuse angle.

[0018] A fastener is disposed on one side of the second extension end of the fixing frame;

[0019] The bayonet is formed on the inner wall of the fastener.

[0020] Also includes:

[0021] The main incineration chamber has multiple downward-sloping air vent arrays on its top inner wall, which are used to guide the flame ejected from the igniter downwards.

[0022] A gas pressure regulating valve is installed on the connecting pipe between the blower and the gas filter.

[0023] The locking rod is angled and is engaged with the fixing member through the locking slot.

[0024] The top end of the rotating shaft is connected to the second clamping member, and the bottom end of the rotating shaft is movably connected to the snap-fit ​​rod.

[0025] The second clamping member has a shape that is wider at the top and narrower at the bottom.

[0026] One side of the first clamping member is fixedly connected to the top edge of one side of the fixing member.

[0027] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes a parallel design of multiple gas cylinders, using natural gas as the fuel supply for the igniter. The inclusion of a gas filter helps remove impurities from the gas, significantly reducing carbon emissions. Furthermore, the design of the first clamping member, second clamping member, rotating shaft, and locking rod ensures the igniter is fixed by clamping. Vertical displacement drives the rotating shaft to rotate, allowing the second clamping member to clamp or separate from the first clamping member, making the disassembly process more flexible and convenient. This design enables quick and easy disassembly of the igniter when maintenance or replacement is needed, reducing the complexity and time required for manual operation. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] like Figure 1-4 As shown, this utility model provides an oil-free combustion device for an incinerator. The oil-free combustion device for an incinerator includes an incinerator 1, a main incineration chamber 2, a gas cylinder 3, a gas filter 4, a blower 5, an igniter 6, a detachable fixing mechanism 7, a first clamping member 71, a second clamping member 72, a rotating shaft 73, a fixing frame 74, and a locking rod 75.

[0037] The main incineration chamber 2 is located within the incinerator 1 and is the core area of ​​the combustion process. Its design aims to provide a high-temperature environment for combustion, ensuring combustion efficiency and safety. Multiple gas cylinders 3 are connected in parallel to a gas filter 4 via gas collecting pipes. The gas filter 4 is located on top of the gas cylinders 3, and its purpose is to provide a stable gas supply. This parallel design increases the gas reserve, ensuring continuous combustion. The filter, located on top of the gas cylinders 3, primarily purifies the gas, removes impurities, and ensures that the igniter 6 can successfully ignite the gas, preventing damage to the igniter 6 from impurities.

[0038] Blower 5 is fixedly installed on one side of incinerator 1. Its air inlet is connected to gas filter 4 via a pipe, and its air outlet is connected to the gas inlet of igniter 6. The nozzle of igniter 6 extends into the main incineration chamber 2; it is the core of the entire combustion device, responsible for igniting the gas. The design of igniter 6 ensures that the flame can be effectively injected into the contents of the main incineration chamber 2 and provides sufficient heat for combustion. Blower 5 blows filtered gas into igniter 6, ensuring that the flame of igniter 6 maintains intensity and has sufficient range. Its air outlet is directly connected to the gas inlet of igniter 6; the increased airflow helps igniter 6 project a flame further, thereby improving combustion efficiency and coverage.

[0039] In this embodiment, the detachable fixing mechanism 7 is installed on one side of the main incineration chamber 2. The detachable fixing mechanism 7 clamps and fixes the igniter 6. The detachable fixing mechanism 7 includes a first clamping member 71, a second clamping member 72, a rotating shaft 73, a fixing frame 74, and a snap-fit ​​rod 75. The first clamping member 71 and the second clamping member 72 are arranged parallel to each other. The igniter 6 is clamped between the first clamping member 71 and the second clamping member 72. The second clamping member 72 is movably connected to the snap-fit ​​rod 75 through the rotating shaft 73. The second clamping member 72 is wider at the top and narrower at the bottom. The turning end of the rotating shaft 73 is movably connected to one side of the fixing member 743. The top end of the rotating shaft 73 is connected to the second clamping member 72, and the bottom end of the rotating shaft 73 is movably connected to the snap-fit ​​rod 75. The locking rod 75 is engaged with the fixing member 743 via the bayonet 744. The locking rod 75 drives the rotating shaft 73 to rotate through vertical displacement, thereby clamping or separating the second clamping member 72 from the first clamping member 71. These two clamping members are used to fix the igniter 6, ensuring its stability and safety. When the incinerator 1 is working, the igniter 6 needs to be stably clamped to prevent positional displacement or loosening under high-temperature conditions.

[0040] In the above embodiments, the design of the rotating shaft 73 and the locking lever 75 provides an adjustable clamping function. The locking lever 75 drives the rotating shaft 73 to rotate through vertical displacement, thereby adjusting the clamping state between the second clamping member 72 and the first clamping member 71. This design makes clamping and disengaging the igniter 6 convenient and flexible. The design of the locking lever 75 engaging with the fixing member 743 through the bayonet 744 facilitates quick disassembly. The angled locking lever 75 provides greater operating space, allowing the operator to easily disassemble the igniter 6 when maintenance is required.

[0041] To facilitate disassembly, a fixing bracket 74 is provided, which also includes: a first extension end 741 located below the second clamping member 72, the first extension end 741 extending obliquely, and a second extension end 742 located to one side of the first extension end 741, with an obtuse angle between the second extension end 742 and the first extension end 741. This design helps increase the stability of the fixing and prevents the igniter 6 from loosening under high temperature or vibration conditions. A fixing member 743 is located on one side of the fixing bracket 74 at the second extension end 742, and a latch 744 is formed on the inner wall of the fixing member 743. One side of the first clamping member 71 is fixedly connected to the top edge of one side of the fixing member 743. The oblique extension of the fixing bracket 74 ensures good support for the igniter 6 when fixed and makes the disassembly and maintenance process easier. The engagement of the extension end with the latching rod 75 allows for up-and-down displacement during disassembly, ensuring a smooth and efficient disassembly process.

[0042] The inner wall of the main incineration chamber 2 is equipped with multiple downward-sloping air vent arrays 8. These air vent arrays 8 are used to guide the flame emitted by the igniter 6 downwards. A gas pressure regulating valve 9 is located on the connecting pipe between the blower 5 and the gas filter 4. The gas pressure regulating valve 9, positioned between the blower 5 and the gas filter 4, regulates the gas pressure. This ensures a stable gas flow and prevents incomplete combustion or equipment damage due to excessively high or low pressure. Stable gas pressure ensures optimal combustion performance of the igniter 6. The downward-sloping air vent array 8 design allows the flame to be more evenly distributed across the incineration area and ensures sufficient contact between the flame and the incinerated items, such as remains. This helps improve combustion efficiency and ensures a thorough incineration process.

[0043] It should be noted that the oil-free combustion device for the incinerator 1 designed in this utility model, when in use, the array of gas cylinders 3 collects and delivers gas to the gas filter 4 at the top. The gas filter 4 introduces the gas into the blower 5 through the pipe. The air outlet of the blower 5 blows the gas into the igniter 6. Finally, the igniter 6 ignites the gas. The air force output by the blower 5 will make the flame of the igniter 6 have a longer range. During the flame-spraying process, the air outlets on the inner wall of the top of the main incineration chamber 2 will output the flame downwards, making it easier to contact the remains. If the igniter 6's barrel is damaged due to high temperature after use and needs to be disassembled for repair, pull the locking rod 75 out of the latch 744 of the fixing member 743, manually push the locking rod 75 downwards. One end of the locking rod 75 will push the rotating shaft 73 connected to it. The turning end of the rotating shaft 73 will rotate, and the bottom end of the rotating shaft 73 will be pushed, causing the second clamping member 72 connected to it at the top to move downwards. The second clamping member 72 will gradually move away from the first clamping member 71, and the igniter 6 barrel held by the two clamping members will loosen until it can be removed. After the new barrel is installed, simply insert it back into the insertion interface on the back of the incinerator 1, then lift the locking rod 75. The second clamping member 72 will gradually clamp the barrel. Then, fix the locking rod 75 in the latch 744 to complete the fixation. The whole process is convenient and quick.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
