Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a regenerative burner. Background Technology

[0002] A regenerative burner is a type of burner that recovers heat from kiln flue gas using regenerative balls to preheat air, thereby achieving uniform heating through alternating combustion. It is primarily used in industrial gas heating and is known for its low emissions and high combustion thermal efficiency. The regenerative burner represents another significant technological advancement following self-preheating burners.

[0003] However, when using regenerative burners, sometimes the inside of the burner is blocked by dust and other impurities, and it is inconvenient to maintain the inside after the blockage. This results in the need to invest more manpower in maintenance, which reduces the overall efficiency of the burner and makes it less convenient to use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a regenerative burner.

[0005] This utility model is achieved by the following technical solution: a regenerative burner, comprising a dust prevention mechanism, a heat storage mechanism, and an exhaust mechanism, wherein the dust prevention mechanism is located at the left end of the heat storage mechanism, and the exhaust mechanism is located at the right end of the heat storage mechanism;

[0006] The dustproof mechanism includes a spray pipe, a fixed sleeve is fixedly connected to the surface of the spray pipe, a rotating threaded block is sleeved on the surface of the fixed sleeve, a first limiting ring is fixedly connected to the inner wall of the spray pipe, a through groove is opened on the surface of the spray pipe, a limit frame is slidably connected to the inner wall of the through groove, a screen is snapped onto the surface of the limit frame, and a connecting ring is fixedly connected to the inner wall of the screen.

[0007] The above technical solution uses a rotating threaded block to disconnect the nozzle from the heat storage pipe and a pulling limit bracket to release the screen limit. This design achieves both dust prevention inside the equipment and quick disassembly and assembly of the nozzle as a whole, making maintenance more convenient and improving practicality.

[0008] As a further improvement to the above scheme, the first limiting ring is located at the left end of the screen, and the screen is located inside the nozzle.

[0009] As a further improvement to the above solution, the heat storage mechanism includes a heat storage tube, a fixed threaded sleeve is fixedly connected to the surface of the heat storage tube, a fixed base is fixedly connected to the lower end of the heat storage tube, a second limiting ring is fixedly connected to the inner wall of the heat storage tube, a heat storage body is fixedly connected to the inner wall of the heat storage tube, and a feed pipe is fixedly connected to the inner wall of the heat storage body.

[0010] The above technical solutions, which use a feed pipe to pass through the heat storage body for spray combustion and a heat storage pipe to protect and insulate internal parts, make the equipment more stable in operation and more convenient to use.

[0011] As a further improvement to the above scheme, the second limiting ring is located at the left end of the heat storage body, and the fixing threaded sleeve is located at the left end of the fixing base.

[0012] As a further improvement to the above solution, the exhaust mechanism includes a connecting pipe, the left end of which is fixedly connected to a fixed base, the surface of which is fixedly connected to a first fixing ring, the inner wall of which is threaded with a bolt, and the surface of which is threaded with a second fixing ring.

[0013] As a further improvement to the above solution, the inner wall of the second fixing ring is fixedly connected to the surface of the heat storage tube, the first fixing ring is connected to the heat storage tube, and the feed tube is located on the inner wall of the connecting ring.

[0014] As a further improvement to the above scheme, the surface of the rotating threaded block is threadedly connected to the inner wall of the fixed threaded sleeve, and the right end of the heat storage tube is engaged with the left end of the second limiting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model incorporates a dustproof mechanism: During equipment exhaust, a screen on the inner wall of the nozzle filters larger dust particles and impurities, preventing them from affecting subsequent processes. When the nozzle is damaged or clogged, rotating the threaded block on the surface of the fixed sleeve moves it to the left, disengaging it from the fixed sleeve. This releases the connection between the heat storage tube and the nozzle, allowing the heat storage tube to be removed. After removing the heat storage tube, pulling the limiting bracket on the inner wall of the channel releases the restriction on the screen, enabling easy removal and maintenance. This design, using the rotating threaded block to release the connection between the nozzle and the heat storage tube and pulling the limiting bracket to release the screen, achieves both dustproofing of the equipment's interior and rapid disassembly and assembly of the nozzle, making maintenance more convenient and improving practicality.

[0017] This utility model incorporates a heat storage mechanism. Specifically, the entire device is fixed to a wall or other equipment via a fixed base. Fuel is then fed into the device from the right end of the feed pipe, causing it to be sprayed out through the heat storage pipe for combustion and heating. When the device exhausts gas, the gas passes through the heat storage body and is discharged through the connecting pipe. The design of using the feed pipe to pass through the heat storage body for fuel spraying and combustion, along with the heat storage pipe's protection and insulation of internal components, makes the device more stable in operation and more convenient to use.

[0027] The dustproof mechanism 1 includes a nozzle 101, a fixed sleeve 102 fixedly connected to the surface of the nozzle 101, a rotating threaded block 103 sleeved on the surface of the fixed sleeve 102, a first limiting ring 104 fixedly connected to the inner wall of the nozzle 101, a through groove 105 opened on the surface of the nozzle 101, a limit frame 106 slidably connected to the inner wall of the through groove 105, a screen 107 snapped onto the surface of the limit frame 106, and a connecting ring 108 fixedly connected to the inner wall of the screen 107. The design of using the rotating threaded block 103 to release the connection between the nozzle 101 and the heat storage pipe 201 and pulling the limit frame 106 to release the limit on the screen 107 achieves both dustproofing of the equipment's interior and quick disassembly and assembly of the nozzle 101 as a whole, making its maintenance more convenient and improving its practicality.

[0028] The first limiting ring 104 is located at the left end of the screen 107, which is located inside the nozzle 101.

[0029] The heat storage mechanism 2 includes a heat storage tube 201, a fixed threaded sleeve 202 fixedly connected to the surface of the heat storage tube 201, a fixed base 203 fixedly connected to the lower end of the heat storage tube 201, a second limiting ring 204 fixedly connected to the inner wall of the heat storage tube 201, a heat storage body 205 fixedly connected to the inner wall of the heat storage tube 201, and a feed pipe 206 fixedly connected to the inner wall of the heat storage body 205. The feed pipe 206 passes through the heat storage body 205 for spray combustion, and the heat storage tube 201 is designed to protect and insulate the internal parts, making the equipment more stable in operation and more convenient to use.

[0030] The second limiting ring 204 is located at the left end of the heat storage body 205, and the fixed threaded sleeve 202 is located at the left end of the fixed base 203.

[0031] The exhaust mechanism 3 includes a connecting pipe 301, a fixed base 302 is fixedly connected to the left end of the connecting pipe 301, a first fixing ring 303 is fixedly connected to the surface of the fixed base 302, a bolt 304 is threadedly connected to the inner wall of the first fixing ring 303, and a second fixing ring 305 is threadedly connected to the surface of the bolt 304.

[0034] The implementation principle of a regenerative burner in this application embodiment is as follows: When using the device, the entire device is first fixed to a wall or other equipment using a fixed base 203. Then, fuel is input from the right end of the feed pipe 206 and sprayed out through the heat storage pipe 201 for combustion heating. When the device exhausts gas, the gas passes through the heat storage body 205 and is discharged through the connecting pipe 301.

When the device exhausts gas, the screen 107 on the inner wall of the nozzle 101 filters out larger dust and other impurities to prevent them from affecting subsequent processes and causing damage inside the nozzle 101. When blocked, rotate the rotating threaded block 103 on the surface of the fixed sleeve 102 to move it to the left, thereby disengaging it from the fixed threaded sleeve 202. At this time, the connection between the heat storage tube 201 and the nozzle 101 is released, and the heat storage tube 201 can be removed. After the heat storage tube 201 is removed, pull the limiting bracket 106 on the inner wall of the through groove 105 to slide it. At this time, the restriction on the screen 107 is released, and the screen 107 can be easily removed for maintenance. The design of using the rotating threaded block 103 to release the connection between the nozzle 101 and the heat storage tube 201 and pulling the limiting bracket 106 to release the restriction on the screen 107 achieves both dust prevention inside the equipment and quick disassembly and assembly of the nozzle 101, making maintenance more convenient and improving practicality.
