Description
Technical Field
[0001] This utility model relates to the field of tempering furnace technology, and in particular to a tempering furnace combustion device. Background Technology
[0002] A tempering furnace is a device used for heat treatment of metallic materials. It is mainly used for tempering metal parts, and can also be used for quenching, annealing, and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, and aluminum plates. The tempering furnace burner is a key component of the tempering furnace. It is mainly used to mix fuel (such as natural gas, liquefied petroleum gas, fuel oil, etc.) with air in a certain proportion and then burn it to provide heat for the tempering furnace so as to meet the temperature conditions required for tempering the workpiece.
[0003] The existing utility model patent with publication number CN222278560U discloses a premixed burner. It describes a method for fixing the main positioning plate and heat insulation bracket using positioning bolts. Based on the length of the auxiliary positioning plate at the bottom of the burner body, a rotating handle can be rotated, causing the active bevel gear to drive the driven bevel gear to rotate, which in turn drives the screw to rotate under the connection of the first and second bearing seats. A translation block threaded onto the screw can, under the guidance of the support rod and the through groove, move the fixed shell and its inner slider left and right, thereby adjusting the left and right position of the threaded rod. Similarly, based on the width of the auxiliary positioning plate, the slider can be moved back and forth within the fixed shell under the connection of the guide support block. After determining the position, the locking bolt is rotated, and under the threaded connection with the screw sleeve, the locking bolt is inserted into the corresponding locking hole. This allows the four mounting holes on the auxiliary positioning plate to be aligned with the four threaded rods for insertion. Then... Simply tighten the compression nut to secure it. This premixed burner has a reasonable structural design and is easy to use. It can be quickly adjusted and installed according to the model and size of the premixed burner to be installed, thus adapting to different equipment support and fixing uses, making it highly efficient and practical. Although it solves the problem of "inability to adapt and install different models and sizes of burner mounting plates", most burners used in tempering furnaces currently use flanges, threads, or other connection methods to connect to the combustion pipes. This is common in some small tempering furnaces or occasions with high installation space requirements. Threaded connections are usually used, but this connection method is prone to thread rusting or seizing after long-term use. Since it is an internal connection of the pipe, this increases the difficulty of disassembling the combustion pipe and burner, thus affecting subsequent maintenance. Therefore, a tempering furnace combustion device is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide a tempering furnace combustion device to address the aforementioned technical problems.
[0005] In order to solve the above-mentioned technical problems, the present invention solves the problem that the threads are prone to rusting or seizing after long-term use, which makes it difficult to disassemble the combustion pipe and the burner.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example
[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A tempering furnace combustion device includes a burner 1 for mixing and igniting fuel and air to provide heat to the tempering furnace to meet the temperature conditions required for tempering workpieces. This is prior art and will not be described in detail. The burner 1 has a connecting pipe 2 for transmitting fuel. One end of the connecting pipe 2 has a mating groove 4 to achieve initial positioning and connection between the combustion pipe 3 and the connecting pipe 2, which facilitates further tightening via a connecting cylinder 6 and a threaded ring 5. The connecting pipe 2 is connected to the combustion pipe 3 via the mating groove 4 for conveying the fuel and air mixture to the burner 1. One end of the combustion pipe 3 is fixedly connected to a threaded ring 5, which tightly connects the combustion pipe 3 and the connecting cylinder 6 through a threaded connection, thereby achieving a stable connection between the combustion pipe 3 and the connecting pipe 2.
[0033] The connecting cylinder 6 is slidably connected to the surface of the connecting pipe 2. The sliding method can be a combination of a sliding groove and a sliding block. The connecting cylinder 6 consists of two half-cylinders 61. The design of the two half-cylinders 61 allows the two half-cylinders 61 to be separated when rust or seizing occurs at the connection between the connecting cylinder 6 and the threaded ring 5. This facilitates the quick separation and maintenance of the burner 1 and the combustion pipe 3 by the staff. Two docking blocks 62 are fixedly connected to the top and bottom of one half-cylinder 61, and two locking blocks 63 are fixedly connected to the top and bottom of the other half-cylinder 61. A disassembly part 7 is provided on one side of the connecting cylinder 6. Internal threads are distributed on one side of the inner wall of the half-cylinder 61, and external threads are distributed on the surface of the threaded ring 5. The connecting cylinder 6 and the threaded ring 5 are threadedly connected.
[0034] Preferably, a locking groove 64 is provided on one side wall of the docking block 62, and the docking block 62 is engaged with the locking block 63 through the locking groove 64. Both the docking block 62 and the locking block 63 have through holes 65 on their sides for initial positioning of the two half cylinders 61.
[0035] Preferably, the disassembly component 7 includes two side blocks 71 fixed to the outer wall of the half-cylinder 61. A bidirectional threaded rod 72 is rotatably connected between the two side blocks 71. The threaded structure of the rod allows the two movable half-rings 74 to move relative to or away from each other, thereby driving the positioning block 75 to engage or disengage with the through hole 65 and the locking block 63. One end of the bidirectional threaded rod 72 rotatably passes through the surface of one of the side blocks 71 and is fixedly connected to a knob 73. Both ends of the bidirectional threaded rod 72 are threadedly connected to movable half-rings 74. The movable half-rings 74 are slidably connected to the half-cylinder 61. The top and bottom of one side wall of the movable half-rings 74 are fixedly connected to positioning blocks 75, providing a reliable positioning and fixing method for the connection of the two half-cylinders 61, preventing the half-cylinders 61 from loosening or separating during use, and ensuring the normal function of the connecting cylinder 6. One end of the positioning block 75 is engaged with the locking block 63 in the same location through the through hole 65.
[0036] Preferably, a sealing cylinder 8 is fixedly connected to the edge of one end of the connecting pipe 2, and is pressed against the sealing half ring 9 to seal the gap at the joint between the connecting pipe 2 and the combustion pipe 3, preventing the leakage of fuel and air mixture. The sealing cylinder 8 is placed at one end of the combustion pipe 3, and a sealing half ring 9 is provided between the half cylinder 61 and the sealing cylinder 8, and the sealing half ring 9 is fixedly connected to the half cylinder 61.
[0037] The usage process of the tempering furnace combustion device provided by this utility model is as follows: When connecting the connecting pipe 2 to the combustion pipe 3, firstly, the connecting cylinder 6 is moved to the maximum distance to one side by hand. Then, one end of the combustion pipe 3 is inserted into the inner cavity of the connecting groove 4 through the inner cavity of the half-cylinder 61. At this time, part of the sealing soft cylinder 8 covers one end of the combustion pipe 3, while part of the half-cylinder 61 abuts against the threaded ring 5. The combustion pipe 3 is rotated so that the threaded ring 5 is threadedly connected to the connecting cylinder 6. When the threaded ring 5 is completely submerged in the interior of the half-cylinder 61, one end of the combustion pipe 3 will abut against the inner wall of the connecting groove 4. Therefore, the half-cylinder... 61 has moved to the maximum distance on the surface of the connecting pipe 2 toward the combustion pipe 3, which makes it impossible for the combustion pipe 3 to move after it is connected to the connecting pipe 2. Thus, the connection between the burner 1 and the combustion pipe 3 is completed. When the threaded part of the half cylinder 61 and the threaded ring 5 is rusted and seized, the operator can manually turn the knob 73 as needed to rotate the bidirectional threaded rod 72, so that the two moving half rings 74 move relative to each other until the part that is positioned 75 is completely disengaged from the through hole 65 on the locking block 63. In this way, the two half cylinders 61 are separated so that the combustion pipe 3 and the burner 1 can be disassembled.
