Description

Technical Field

[0001] The utility model relates to the field of burner combined connectors, in particular to a low-nitrogen burner combined connector. Background Technique

[0002] A low-nitrogen burner is a device that adds a blower, an induced draft fan, a frequency converter, uses a control valve, and integrates multiple circuits to the traditional burner to make clean energy and the burner operate to provide more efficient heat energy for the boiler. It is divided into heavy oil burners, gas burners, and dual-fuel burners.

[0003] A key part of the existing low-nitrogen burner is the burner head, which allows gas to burn inside the burner head. Subsequently, the gas will be burned repeatedly. However, a connector is added outside the burner head to prevent the outer wall of the burner head from causing harm to people due to high temperature during combustion.

[0004] The existing connectors are usually fixed to their outer walls by multiple bolts. However, during installation and disassembly, it is rather troublesome and requires the use of tools to turn the bolts multiple times to remove the bolts, resulting in low work efficiency for the installation and disassembly of the connectors. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a low-nitrogen burner combined connector to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A low-nitrogen burner combined connector includes a protective plate. The number of the protective plates is two groups. The two groups of protective plates form a connector. A snap ring is fixed at the end of the protective plate, and a groove is provided inside the snap ring. Horizontal plates are fixed on both sides of the protective plate, and multiple clamping plates are movably installed on the outer walls of the horizontal plates. A clamping groove is provided on one side of the clamping plate, and the inner wall of the clamping groove fits with the outer wall of the horizontal plate. A threaded hole is provided at the top of the horizontal plate, and a bolt is provided inside the threaded hole.

[0007] By adopting the above technical solution, the problem of inconvenient disassembly of the existing burner combined connector is solved. The snap ring is clamped at the connection of the burner flange, and then the two protective plates are fixed by two bolts, thus replacing the method of fixing with multiple bolts, reducing the use of bolts, and also facilitating the installation of the protective plate. Subsequently, the clamping plates are clamped on the outer walls of the horizontal plates, so that the clamping effect of the protective plate during use will be better.

[0008] The present utility model is further arranged such that multiple protrusions are fixed on the inner wall of the protective plate, and the multiple protrusions are evenly distributed inside the protective plate.

[0009] By adopting the above technical solution, multiple groups of raised portions are provided to reduce the contact area between the protective plate and the burner. Both the protective plate and the raised portions are made of aluminum, so that during use, better heat dissipation for the burner can be achieved. The heat of the burner is transferred to the protective plate through the aluminum raised portions, thereby enabling the protective plate to have a larger contact area with the outside world and better dissipate heat.

[0010] The present utility model is further configured such that a plurality of heat dissipation holes are formed in the outer wall of the protective plate, and the inner wall diameter of the heat dissipation holes is set to be larger on the outside and smaller on the inside.

[0011] By adopting the above technical solution, the plurality of heat holes formed facilitate heat dissipation for the burner, thereby facilitating contact between the outside gas and the burner. Since the inner wall diameter of the heat dissipation holes is set to be larger on the outside and smaller on the inside, when the outside gas flows through, better heat dissipation for the burner can be achieved, enabling the radiator to be quickly cooled.

[0012] The present utility model is further configured such that limiting holes are formed in the top of the clamping plate and the outer wall of the cross plate, and insertion rods are arranged inside the limiting holes.

[0013] By adopting the above technical solution, the formed limiting holes facilitate cooperation with the insertion rods, such that the clamping plate is not easily separated from the cross plate. The rectangular insertion rods can avoid the problem of the insertion rods rotating.

[0014] The present utility model is further configured such that a magnetic block is fixed to the end portion.

[0015] By adopting the above technical solution, the provided magnetic block can fix the insertion rod, such that the insertion rod is not easily separated from the clamping plate.

[0016] The present utility model is further configured such that convex blocks are fixed to the inner wall of the card slot, and the two sides of the convex blocks are provided with inclined surfaces.

[0017] By adopting the above technical solution, the inclined surfaces provided on both sides of the convex blocks make it more convenient to install the convex blocks, thereby enabling the clamping plate to be quickly clamped at the designated position.

[0018] The present utility model is further configured such that a card slot is formed in the outer wall of the cross plate, and the inner wall of the card slot fits with the outer wall.

[0019] By adopting the above technical solution, the formed card slot can increase the contact area between the convex block and the cross plate, thereby enabling the clamping plate to be installed more stably.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] The utility model solves the problem that the existing burner combined connector is inconvenient to disassemble by setting a clamping plate, bolts, inserting rods and magnetic blocks. The clamping ring is clamped at the connection of the burner flange, and then two groups of bolts are used to fix two groups of protective plates, thus replacing the method of fixing with multiple bolts, reducing the use of bolts, and also facilitating the installation of the protective plates. Then, the clamping plate is clamped on the outer wall of the cross plate, so that the clamping effect of the protective plate during use will be better. Then, the inserting rod is inserted into the limiting hole, so that the clamping plate will not fall off easily, making the installation of the connector more convenient and not affecting the heat dissipation of the burner. The contact area between the burner and the protective plate can be reduced by the protrusions, and then the heat dissipation can be facilitated through the arranged heat dissipation holes.

Detailed Embodiment

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0028] The embodiments of the present utility model will be described below according to its overall structure.

[0029] A low-nitrogen burner combined connector, such as Figure 1 - Figure 4As shown, it includes a protective plate 1, the number of protective plates 1 is two groups, and the two groups of protective plates 1 constitute a connecting piece. A snap ring 2 is fixed at the end of the protective plate 1, and a groove 11 is arranged inside the snap ring 2. A transverse plate 3 is fixed on both sides of the protective plate 1, and a plurality of groups of card plates 6 are movably installed on the outer wall of the transverse plate 3. The card plates 6 are engaged with the outer wall of the transverse plate 3. When engaging, it is only necessary to slightly align the protrusion 14 with the card groove 10, and then push the card plate 6. Since the inclined surfaces on both sides of the protrusion 14 are arranged, when the protrusion 14 moves When the card plate 6 is installed, it will gradually enter the inner wall of the slot 10, increasing the contact area with the cross plate 3, making the card plate 6 more stable during installation. A slot 61 is provided on one side of the card plate 6, and the inner wall of the slot 61 fits with the outer wall of the cross plate 3. A threaded hole 13 is provided on the top of the cross plate 3, and a bolt 7 is provided inside the threaded hole 13. The two sets of protective plates 1 are clamped on the outside of the burner, and then the clamping ring 2 is clamped on the connection of the flange, and then the two sets of protective plates are fixed by two sets of bolts 7.

[0030] See also Figure 1 A plurality of groups of protrusions 4 are fixed to the inner wall of the protective plate 1, and the plurality of groups of protrusions 4 are evenly distributed inside the protective plate 1. The plurality of groups of protrusions 4 can reduce the contact area between the protective plate 1 and the burner. The protective plate 1 and the protrusions 4 are both made of aluminum, so the burner can be better dissipated during use. The heat of the burner is transferred to the protective plate 1 through the aluminum protrusions 4, thereby increasing the contact area between the protective plate 1 and the outside world and achieving better heat dissipation.

[0031] See also Figures 1 - 3 The outer wall of the protective plate 1 is provided with a plurality of heat dissipation holes 5, and the inner wall diameter of the heat dissipation holes 5 is set to be larger on the outside and smaller on the inside. The plurality of heat dissipation holes 5 can conveniently dissipate heat from the burner, thereby facilitating contact between the outside gas and the burner. Since the inner wall diameter of the heat dissipation holes 5 is set to be larger on the outside and smaller on the inside, when the outside gas flows through, it can better dissipate heat from the burner, so that the radiator can be cooled quickly.

[0032] See also Figure 3 and Figure 4 The top of the card plate 6 and the outer wall of the cross plate 3 are both provided with a limiting hole 9, and an insertion rod 12 is arranged inside the limiting hole 9, and the insertion rod 12 is arranged as a rectangular rod. The limiting hole 9 can be conveniently matched with the insertion rod 12, so that the card plate 6 will not be easily separated from the cross plate 3, and the rectangular setting of the insertion rod 12 can avoid the problem of the insertion rod 12 rotating.

[0033] See also Figure 1 A magnetic block 8 is fixed to the end of the plug rod 12, and the material of the card plate 6 is iron. The magnetic block 8 can fix the plug rod 12 so that the plug rod 12 will not easily fall off the card plate 6.

[0034] See alsoFigure 4 , a convex block 14 is fixed on the inner wall of the card slot 61, and the two sides of the convex block 14 are provided with inclined surfaces. The inclined surfaces on both sides of the convex block 14 make it more convenient to install the convex block 14, so that the card board 6 can be quickly clamped at the designated position.

[0035] Please refer to Figure 2 and Figure 4 , a card slot 10 is opened on the outer wall of the cross plate 3, and the inner wall of the card slot 10 fits with the outer wall of the convex block 14. By opening the card slot 10, the contact area between the convex block 14 and the cross plate 3 can be increased, so that the card board 6 is installed more stably.

[0036] The working principle of the present utility model is as follows: when in use, the two groups of protection plates 1 are clamped outside the burner, then the snap ring 2 is clamped at the connection of the flange, and then the two groups of protection plates are fixed by the two groups of bolts 7. Then the card board 6 is clamped on the outer wall of the cross plate 3. When clamping, only need to slightly align the convex block 14 with the card slot 10, and then push the card board 6. Since the two sides of the convex block 14 are provided with inclined surfaces, when the convex block 14 moves, it will gradually enter the inner wall of the card slot 10, increasing the contact area with the cross plate 3, making the card board 6 more stable when installed. Then the insertion rod 12 is inserted into the inner part of the limit hole 9, and the magnet 8 is adsorbed on the top of the card board 6 to ensure that the card board 6 will not shake easily during use, making the protection plate 1 more stable when installed and disassembled.
