Description

Technical Field

[0001] The present application relates to the technical field of heating hood burner installation, and in particular to an installation device for a heating hood burner of a full hydrogen hood furnace. Background Art

[0002] The heating hood is the main equipment of the bell-type furnace, which forms a combustion chamber with the inner cavity. The heating hood is mainly composed of a hood body, a preheater, a burner body and a furnace lining in the furnace cavity. The hood body is the skeleton of the heating hood. The equipment and parts of the heating hood are attached to this hood body. A combustion system with an ignition electrode is arranged in the hood body. The burner body includes a mixing chamber, a gas pipeline and an air pipeline. Gas and air are introduced into the mixing chamber through the gas pipeline and the air pipeline to form a mixed gas. The mixed gas flows rapidly along the middle channel of the mixing chamber toward the hood body and then reaches the combustion tube. After the ignition electrode is ignited, the mixed gas burns in the combustion tube. The high-temperature exhaust gas generated after combustion continues to accelerate along the combustion tube toward the inner cavity under the action of pressure, and forms a fire jet at the head of the combustion tube constriction, releasing a large amount of heat into the inner cavity of the heating hood.

[0003] The existing heating hood inner cavity is often a vertically arranged cylindrical structure, with an exhaust pipe vertically connected to the side wall of the inner cavity, and the hood body horizontally installs the burner body on one side of the inner cavity wall, so that the high-temperature exhaust gas generated after combustion can quickly flow into the inner cavity along the radial direction of the inner cavity.

[0004] Considering that the high-temperature exhaust gas will flow back after reaching the inner wall of the inner cavity, the exhaust gas will flow horizontally back and forth in the inner cavity of the heating hood, making it difficult for the exhaust gas to quickly enter the exhaust pipe and be discharged, thereby causing excessive pressure inside the combustion chamber. Utility Model Content

[0005] In order to improve the problem that exhaust gas is difficult to be discharged quickly, resulting in excessive pressure inside the combustion chamber, the present application provides an installation device for a heating hood burner of a full hydrogen hood furnace.

[0006] The present application provides a device for installing a heating hood burner of a full hydrogen bell-type furnace using the following technical solution:

[0007] A mounting device for a heating hood burner of a full hydrogen bell-type furnace, used to fix the mixing chamber of the burner body on the side wall of the heating hood, comprising:

[0008] A fixed frame, which is fixedly sleeved on one end of the mixing chamber, and the fixed frame is vertically arranged with the mixing chamber;

[0010] The connecting piece is arranged between the fixing frame and the cover body, and is used to tightly connect the fixing frame and the angle pad to the cover body, so that the mixing chamber is inclinedly arranged on the side wall of the cover body.

[0011] Furthermore, the connecting member is configured as a bolt, and a threaded hole adapted to the bolt thread is vertically opened on the side wall of the cover body, and mounting holes for the bolts to pass through are opened on the angle pad and the fixed frame. During installation, the bolts pass through the mounting holes on the fixed frame and the angle pad in turn and are connected to the threaded holes on the side wall of the cover body, and the large head of the bolt is pressed against the side wall of the fixed frame away from the angle pad.

[0012] Furthermore, a pad is provided on the side of the fixing frame away from the angle pad, and the big head end of the bolt is pressed against the fixing frame through the pad, and one side of the pad is parallel to and pressed against the end face of the big head end of the bolt, and the other side is parallel to and pressed against the side face of the fixing frame away from the angle pad.

[0013] Furthermore, the cushion block is sleeved on the bolt.

[0014] Furthermore, a side surface of the fixing frame away from the angle pad is provided with an embedding groove for the pad to be embedded in, and the pad is partially embedded in the embedding groove.

[0015] Furthermore, an anti-wear layer is provided between the pad and the big head end of the bolt.

[0016] Furthermore, an anti-slip layer is provided between the inner wall of the embedding groove and the cushion block.

[0017] Furthermore, sealing rings are provided between the angle pad and the fixed frame, and between the angle pad and the cover body.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1.

[0020] 2. By adding a pad between the fixed frame and the big head of the bolt, the big head of the bolt is in surface contact with the pad, ensuring that under the action of the pad, the bolt can stably press the fixed frame and the angle pad against the side wall of the cover.

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present application discloses an installation device for a heating hood burner of a full hydrogen bell-type furnace, which is used to fix the mixing chamber 1 of the burner body on the side wall of the hood body 2 of the heating hood, so that the mixing chamber 1 is connected to the inner cavity of the bell-type furnace through the hood body 2 to form a combustion chamber. Figure 1 , Figure 2 and Figure 3The installation device for the heating hood burner of the full hydrogen bell-type furnace includes a fixed frame 3 fixedly sleeved on one end of the mixing chamber 1, an angle pad 4 arranged between the fixed frame 3 and the side wall of the hood body 2, and a connector arranged between the fixed frame 3 and the hood body 2 and used to tightly connect the fixed frame 3 and the angle pad 4 to the hood body 2. The fixed frame 3 is arranged vertically with the mixing chamber 1, and a gas pipeline and an air pipeline are arranged at one end of the mixing chamber 1 away from the fixed frame 3, so that gas and air are introduced into the mixing chamber 1 through the gas pipeline and the air pipeline to form a mixed gas. A guide hole is opened in the middle of the angle pad 4, so that the mixed gas in the mixing chamber 1 can enter the hood body 2 through the guide hole along the middle channel of the mixing chamber 1. An air inlet for the mixed gas to enter is provided on one side wall of the cover body 2, and an air outlet connected to the inner cavity of the hood of the hood-type furnace is provided on the other side wall; a guide tube 13 and a combustion tube 14 are horizontally arranged in the cover body 2, one end of the guide tube 13 is fixed at the air inlet, so that the mixed gas in the mixing chamber 1 can smoothly enter the guide tube 13, and the other end of the guide tube 13 is connected to the combustion tube 14, and an ignition electrode is arranged in the combustion tube 14, so that after the mixed gas enters the combustion tube 14 through the guide tube 13, the ignition electrode is ignited, so that the mixed gas burns in the combustion tube 14, and is sprayed into the inner cavity through the air outlet of the cover body 2, thereby releasing a large amount of heat into the inner cavity of the heating hood.

[0028] Since a large amount of exhaust gas is generated when the mixed gas is burned, the high-temperature exhaust gas is quickly pushed into the inner cavity of the heating hood as the mixed gas continues to flow, and an exhaust pipe is vertically installed on the inner cavity. If the flow direction of the mixed gas is consistent with the radial direction of the inner cavity, the high-temperature exhaust gas will flow back and forth horizontally in the inner cavity, making it difficult for the exhaust gas to quickly enter the vertically installed exhaust pipe. Therefore, the flow direction of the mixed gas needs to be adjusted. Figure 1 , Figure 2 and Figure 3 The side of the angle pad 4 close to the fixed frame 3 and the side of the angle pad 4 close to the cover body 2 are arranged at an angle, and sealing rings 12 are arranged between the angle pad 4 and the fixed frame 3 and between the angle pad 4 and the cover body 2, so that under the connection action of the connecting piece, the mixing chamber 1 is sealed and obliquely installed on the side wall of the cover body 2. When gas and air are introduced into the mixing chamber 1 through the gas pipeline and the air pipeline to form a mixed gas, the mixed gas enters the cover body 2 through the guide hole along the middle channel of the mixing chamber 1, and the mixing chamber 1 is set at an angle with the side wall of the cover body 2 under the cushion of the angle pad 4, that is, the central axis of the mixing chamber 1 is not parallel to the central axis of the guide tube 13 and the combustion tube 14, so that the flow direction of the mixed gas in the guide tube 13 and the combustion tube 14 is set at an angle with the central axis of the combustion tube 14, so that the high-temperature exhaust gas generated by the combustion in the combustion tube 14 is pushed into the inner cavity at a certain inclination angle, which accelerates the flow speed of the exhaust gas in the inner cavity along the vertical direction, thereby improving the efficiency of exhaust gas discharge through the exhaust pipe.

[0029] In order to enable the mixing chamber 1 to be stably and conveniently fixed on the side wall of the cover body 2, refer to Figure 1 , Figure 2 and Figure 3 , the angle pad 4 is set to be wedge-shaped, and the four corners of the fixed frame 3 and the angle pad 4 are correspondingly penetrated with mounting holes 7. In the embodiment of the present application, the connecting member is set to be a bolt 5, and four bolts 5 are provided, and the four bolts 5 correspond to the four groups of mounting holes 7 one by one. Four threaded holes 6 adapted to the threads of the bolts 5 are vertically opened on the side wall of the cover body 2. When it is necessary to obliquely install the mixing chamber 1 on the side wall of the cover body 2, the bolts 5 are successively passed through the mounting holes 7 on the fixed frame 3 and the angle pad 4, and the bolts 5 are rotated so that the bolts 5 are connected with the threaded holes 6 on the side wall of the cover body 2 until the large head of the bolt 5 is pressed against the side wall of the fixed frame 3 away from the angle pad 4. At this time, the mixing chamber 1 is stably and obliquely installed on the side wall of the cover body 2 under the connection of the four bolts 5 and the padding of the angle pad 4, and is connected with the guide tube 13 in the cover body 2 through the guide hole. In other embodiments, the connecting piece is configured as a buckle fixed on the side wall of the cover body 2, such as a tiger buckle, and the buckle presses against the edge of the fixing frame 3 so that the fixing frame 3 and the angle pad 4 are tightly fixed on the side wall of the cover body 2, ensuring that the mixing chamber 1 is stably tilted and connected to the side wall of the cover body 2.

[0030] Since the threaded hole 6 on the cover body 2 is arranged perpendicular to the side wall of the cover body 2, when the bolt 5 presses and fixes the fixing frame 3 and the angle pad 4 on the cover body 2, the large head of the bolt 5 and the side wall of the fixing frame 3 away from the angle pad 4 are arranged at an angle. At this time, the contact area between the large head of the bolt 5 and the side wall of the fixing frame 3 is small, so the tightening effect of the bolt 5 on the fixing frame 3 is poor. For this reason, refer to Figure 1 , Figure 2 and Figure 3 A pad 8 is provided on the side of the fixed frame 3 away from the angle pad 4, and the large head of the bolt 5 is pressed against the fixed frame 3 through the pad 8, and one side of the pad 8 is parallel to and pressed against the end face of the large head of the bolt 5, and the other side is parallel to and pressed against the side of the fixed frame 3 away from the angle pad 4. By adding the pad 8, the large head of the bolt 5 is in surface contact with the pad 8, ensuring that under the action of the pad 8, the bolt 5 can stably press the fixed frame 3 and the angle pad 4 against the side wall of the cover body 2.

[0031] In order to prevent the pad 8 from slipping off between the big end of the bolt 5 and the fixing frame 3, thereby affecting the padding effect of the pad 8, refer to Figure 1 , Figure 2 and Figure 3, the pad 8 is movably sleeved on the bolt 5, so that when the bolt 5 passes through the mounting hole 7 and is threadedly connected with the threaded hole 6, the pad 8 is always hung on the bolt 5 and located between the big head end of the bolt 5 and the fixed frame 3, so as to achieve padding for the big head end of the bolt 5. In the process of rotating the bolt 5 so that the bolt 5 is pressed against the pad 8, the pad 8 is easily rotated together with the big head end of the bolt 5 driven by the big head end of the bolt 5. For this reason, a groove 9 for the pad 8 to be inserted is provided on the side of the fixed frame 3 away from the angle pad 4, and the pad 8 is partially inserted into the groove 9, so that when the bolt 5 is rotated, the pad 8 will not rotate with the bolt 5 under the action of the inserting of the groove 9, so as to ensure that after the bolt 5 is tightened, one side of the pad 8 is parallel to and pressed against the end face of the big head end of the bolt 5, and the other side is parallel to and pressed against the side of the fixed frame 3 away from the angle pad 4. At the same time, an anti-slip layer 11 is provided between the inner wall of the embedding groove 9 and the cushion block 8. The anti-slip layer 11 is specifically a damping pad bonded to the inner wall of the embedding groove 9, so that after the cushion block 8 is embedded in the embedding groove 9, the damping pad abuts against the cushion block 8 on all sides, making it difficult for the cushion block 8 to fall off from the embedding groove 9.

[0032] To prevent the pad 8 from being worn and affecting its padding effect, refer to Figure 2 and Figure 3 An anti-wear layer 10 is provided between the pad 8 and the big end of the bolt 5. In the embodiment of the present application, the anti-wear layer 10 is a rubber layer bonded to the pad 8. In other embodiments, the anti-wear layer 10 is a diamond coating coated on the pad 8. It is ensured that during the process of tightening the bolt 5, the big end of the bolt 5 is not easy to wear the pad 8, thereby extending the service life of the pad 8.

[0033] The implementation principle of the installation device for the heating hood burner of a full hydrogen hood-type furnace according to the embodiment of the present application is as follows: first, the pad 8 is embedded in the embedding groove 9 on the fixed frame 3, and then the bolts 5 are successively passed through the mounting holes 7 on the fixed frame 3 and the angle pad 4, and the bolts 5 are rotated so that the bolts 5 are connected to the threaded holes 6 on the side walls of the hood body 2 until the large heads of the bolts 5 are tightly pressed against the pad 8. At this time, the mixing chamber 1 is stably and tiltedly installed on the side walls of the hood body 2 under the connection action of the four bolts 5 and the cushioning of the angle pad 4, and is connected to the guide tube 13 in the hood body 2 through the guide holes.

[0034] Gas and air are introduced into the mixing chamber 1 through the gas pipeline and the air pipeline to form a mixed gas, and the mixed gas enters the cover body 2 through the guide hole along the middle channel of the mixing chamber 1, and the mixing chamber 1 is arranged at an angle with the side wall of the cover body 2 under the cushion of the angle pad 4, that is, the central axis of the mixing chamber 1 is not parallel to the central axis of the guide tube 13 and the combustion tube 14, so that the flow direction of the mixed gas in the guide tube 13 and the combustion tube 14 is arranged at an angle with the central axis of the combustion tube 14, so that the high-temperature exhaust gas generated by the combustion in the combustion tube 14 is pushed into the inner cavity at a certain inclination angle, which accelerates the flow speed of the exhaust gas in the inner cavity along the vertical direction, thereby improving the efficiency of exhaust gas discharge through the exhaust pipe.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
