Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a regulating oil and gas burner. Background Art

[0002] A burner is a device that uses fuel and air to spray out mixed combustion in a certain way. Traditional burners are usually divided into oil burners and gas burners, but they cannot switch between oil and gas at the same time, resulting in low combustion efficiency and high harmful emissions. In order to solve the above problems, high-efficiency, energy-saving and environmentally friendly oil and gas dual-purpose burners are now used.

[0003] However, the existing adjustable oil and gas burners have certain defects in actual use. When the oil supply and gas supply devices are connected, they are mostly connected and assembled by connecting flanges. After long-term use, the sealing performance of the sealing ring is reduced, which will affect the sealing effect and even cause oil or gas leakage, posing certain safety hazards.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides an embodiment: an adjustable oil and gas burner, including a burner body 2 (mainly including a combustion chamber, an air jet burner, an oil jet burner, etc., which is a relatively mature technology and will not be described in detail here). It is an adjustable multi-purpose burner that can burn oil or gas, or a mixture of the two, and is adjusted according to actual conditions. It is a relatively mature technology and will not be described in detail here. A base 1 with a mounting assembly can be welded to its bottom end. In order to facilitate its assembly, mounting holes for mounting screws 3 to engage with the mounting holes are equidistantly provided on its circumferential side surfaces, and an oil inlet pipe 4 and a gas inlet pipe 5 are respectively provided on the side walls of the burner body 2. In order to facilitate adjustment, both are equipped with regulating valves 6 (which can be flow regulating valves 6, etc., which can be adjusted according to needs to control their opening and closing, which is a relatively mature technology and will not be described in detail here), which can conveniently adjust the oil and gas.

[0023] See also Figure 1-Figure 5In order to ensure the sealing performance during connection and use, the oil inlet pipe 4 and the gas inlet pipe 5 are connected to the connecting pipe 7 through a connecting mechanism, and the ends thereof are respectively connected to the oil supply device and the gas supply device, so as to facilitate supply during combustion, and the connecting pipe 7 is connected and sealed with the two by a sealing mechanism, and the structures of the connecting mechanism and the sealing mechanism on the oil inlet pipe 4 and the gas inlet pipe 5 are the same, wherein the sealing mechanism comprises an insert ring 20 welded to one end of the connecting pipe 7 near the connecting mechanism (which is convenient for inserting into the oil inlet pipe 4 and the gas inlet pipe 5), and a sealing ring 22 is bonded to the outside of the insert ring 20 (which can be interference fit with the inner wall of the oil inlet pipe 4 and the gas inlet pipe 5 to ensure the sealing effect of the plug-in connection), and in order to further improve the sealing effect, positioning and fixing can also be performed. , to improve the firmness of the connection, an inflatable sealing bag 19 is arranged on the inner wall of the oil inlet pipe 4 and the air inlet pipe 5 (the material of which can be elastic material such as rubber, and a silicone sealing layer can be bonded to the outside to improve the sealing effect, which is a relatively mature technology and will not be described in detail here), and a corresponding plug ring 20 is provided with a sealing groove 21 on the outside that is interference fit with the inflatable sealing bag 19, which is convenient for sealing and positioning after inflation, and the inflatable sealing bag 19 is provided with an air charging and discharging pipe 18 for convenient inflation and deflation thereof (the principle is the same as the valve core of a bicycle tire, which is a relatively mature technology and will not be described in detail here), the air charging and discharging pipe 18 passes through the oil inlet pipe 4 and extends to the outside and can be engaged with a sealing plug 9 through a thread, which can be sealed during use to prevent dust and the like from entering the inside.

[0024] See also Figure 1-Figure 5 In order to facilitate the connection and use, ensure the stability of use, and facilitate the subsequent disassembly operation, it is relatively simple and convenient. The connection mechanism includes a connecting flange 8 welded on the oil inlet pipe 4, the air inlet pipe 5 and the side wall of the connecting pipe 7. A sealing gasket can be arranged between the mutually connected connecting flanges 8 to improve the sealing performance. A plug-in hole 11 is opened on the side of the connecting flange 8, and a plug-in column 13 is inserted therein. In order to ensure the firmness of the plug-in and avoid falling off, the plug-in holes 11 on the connecting flange 8 are opened on the side walls away from each other. There is a positioning groove of the positioning component, and a support plate 12 is welded at one end of the plug-in column 13, which can be engaged with the positioning groove, and a sliding cavity 17 is opened at the other end. Two groups of sliding rods 15 with sliding structures are symmetrically fixed in the sliding cavity 17. Two movable plates 14 are slidably matched on the sliding rod 15, and a spring 16 is sleeved between the two movable plates 14 on the outside of the sliding rod 15. The movable plate 14 is located outside the sliding cavity 17. A positioning block 10 is welded with the positioning groove, which is adapted for positioning, so that it can be conveniently fixed after plugging in to ensure a firm connection.

[0025] Working principle: When the utility model is in use, the plug ring 20 on the connecting pipe 7 is plugged into the oil inlet pipe 4 and the air inlet pipe 5 respectively, and sealed by the sealing ring 22. At this time, the air is inflated through the charging and discharging pipe 18, and the inflatable sealing bag 19 is inflated and expanded, and contacts and seals with the sealing groove 21. At the same time, it can also assist in positioning to ensure the firmness of the plug-in. At the same time, the connecting flange 8 is matched and aligned, and the positioning block 10 is pressed, and the two moving plates 14 slide on the slide rod 15 to approach each other. The spring 16 is forced to shrink and store potential energy, and then the plug-in column 13 is inserted into the plug-in hole 11. After the support plate 12 enters the positioning groove, the positioning block 10 is lost. Under the action of potential energy, the two positioning blocks 10 are reset away from each other and enter into another positioning groove, so that the plug-in column 13 can be positioned and fixed to complete the connection assembly, which can ensure stability during use. The regulating valve 6 on the oil inlet pipe 4 and the air inlet pipe 5 can be opened or closed according to the needs of use, which is convenient for use. When disassembling, the positioning block 10 can be pressed and then pushed to remove the plug-in column 13 from the plug-in hole 11, and then the sealing plug 9 can be unscrewed, and the inflatable sealing bag 19 can be deflated through the inflation and deflation pipe 18 to lose the locking seal. At this time, the connecting pipe 7 and the oil inlet pipe 4 or the connecting pipe 7 and the air inlet pipe 5 can be disassembled to facilitate maintenance or replacement operations.
