Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a natural gas heating device for the production of packaging steel strips. Background Technology

[0002] Packaging steel strapping is a material used for binding, securing, or reinforcing goods. It is typically made of low-carbon steel and undergoes certain processing and surface treatments to improve its strength and corrosion resistance. A packaging steel strapping heating device is a device used to heat the packaging steel strapping, primarily to increase its plasticity to facilitate subsequent binding and securing operations.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Currently, most existing heating devices in the production of packaging steel strips mostly use medium-frequency furnaces for heating, and the generated waste gas is cooled by spraying and then adsorbed by activated carbon before being discharged. Because this method has high energy consumption and low treatment efficiency, it is difficult to meet ultra-low emission requirements. Therefore, those skilled in the art have provided a natural gas heating device for the production of packaging steel strips to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a natural gas heating device for the production of packaging steel strips. By installing a burner on the inner bottom surface of the heat-resistant fiber lining, natural gas can be used for combustion heating, which can effectively treat the rolling oil and organic waste gas on the surface of the steel strip, and also preheat the steel strip, thereby effectively reducing energy consumption and achieving ultra-low emissions.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A natural gas heating device for packaging steel strip production includes a furnace body steel structure. A refractory fiber lining is embedded and fixedly installed on the inner surface of the furnace body steel structure. A burner is fixedly installed at the midpoint of the front and rear ends of the inner bottom surface of the refractory fiber lining. A connecting device is embedded and fixedly installed at the midpoint of the upper and lower ends of the furnace body steel structure. An explosion-proof valve is embedded at the midpoint of one side of the upper end of the furnace body steel structure.

[0007] A connecting mechanism is embedded and fixedly installed at the midpoint of the front end face of the furnace body steel structure. The connecting mechanism includes a connecting pipe. Multiple clamping pipes are snapped onto the upper and lower ends of the outer surface of the connecting pipe near the front end. A gas supply pipe is embedded and fixedly installed at the midpoint of the rear end face of the outer surface of the connecting pipe.

[0008] Furthermore, the outer surface of the connecting pipe is embedded with a fixed interface at both the front and rear ends, and the outer surface of the air supply pipe is provided with an upper fixed plate and a lower fixed plate at the upper and lower ends respectively. Rubber columns are provided at the midpoints on both sides between the upper fixed plate and the lower fixed plate.

[0009] Furthermore, a fixing rod is fixedly installed at the midpoint of the lower end face of the lower fixing plate, and a support plate is fixedly installed at the lower end of the midpoint of the front end face of the furnace body steel structure, with the lower end face of the fixing plate fixedly installed on the upper end face of the support plate.

[0010] Furthermore, the gas supply pipe is fixedly embedded at the midpoint of the front end face of the furnace body steel structure, and multiple clamping pipes can be clamped to multiple exhaust gas pipes.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a natural gas heating device for the production of packaged steel strips. After embedding a heat-resistant fiber lining inside the furnace steel structure, the burner can be placed on both sides of the inner bottom surface of the heat-resistant fiber lining. At the same time, a gas transmission pipe is embedded in the rear end face of the furnace steel structure, which can be connected to a natural gas pipeline. Natural gas can then be transported into the furnace steel structure for the burner to use. After the burner ignites the natural gas, it can better burn and heat the steel strips that penetrate into the furnace steel structure, thereby effectively reducing energy consumption.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 4 A natural gas heating device for packaging steel strip production includes a furnace body steel structure 1, a refractory fiber lining 11 is embedded and fixedly installed on the inner surface of the furnace body steel structure 1, a burner 10 is fixedly installed at the midpoint of the front and rear ends of the inner bottom surface of the refractory fiber lining 11, a connecting device 9 is embedded and fixedly installed at the midpoint of the upper and lower end surfaces of the furnace body steel structure 1, and an explosion-proof valve 7 is embedded at the midpoint of one side of the upper end surface of the furnace body steel structure 1.

[0025] A connecting mechanism 2 is embedded and fixedly installed at the midpoint of the front end face of the furnace body steel structure 1. The connecting mechanism 2 includes a connecting pipe 201. Multiple clamping pipes 202 are clamped and installed on the upper and lower ends of the outer surface of the connecting pipe 201 near the front end. A gas supply pipe 205 is embedded and fixedly installed at the midpoint of the rear end face of the outer surface of the connecting pipe 201.

[0026] Specifically, after the refractory fiber lining 11 is embedded inside the furnace steel structure 1, it can effectively control the temperature when the steel strip is burned and heated. The burners 10 installed on the upper end of both sides of the bottom surface of the refractory fiber lining 11 can ignite the natural gas supplied to the furnace steel structure 1, thereby better heating the steel strip. The connecting devices 9 installed on the upper and lower end of the furnace steel structure 1 can be connected to the upper sealing box 4 and the lower sealing box 3 respectively, so that the steel strip can be conveyed into the furnace steel structure 1 for combustion and heating. The connecting mechanism 2 can better discharge the waste gas generated during the production process into the furnace steel structure 1 for re-combustion, thereby better discharging the gas after combustion.

[0027] Reference Figure 4 The connecting pipe 201 has fixed interfaces 203 embedded and fixed on its outer surface near the front end and the rear end. The air supply pipe 205 has an upper fixed plate 204 and a lower fixed plate 207 on its outer surface near the upper end and the lower end, respectively. Rubber columns 206 are set at the midpoints on both sides between the upper fixed plate 204 and the lower fixed plate 207.

[0028] Specifically, the fixed interface 203 embedded in the connecting pipe 201 allows for more convenient disassembly and maintenance of the connecting pipe 201. After the upper fixed plate 204 and the lower fixed plate 207 are set on the outer surface of the air supply pipe 205, the upper fixed plate 204 and the lower fixed plate 207 can be connected and fixed by bolts. The rubber column 206 can be sleeved on the outer surface of the bolt, thereby playing a buffering and fixing role on the upper fixed plate 204 and the lower fixed plate 207.

[0029] Reference Figure 3 and Figure 4 A fixing rod 12 is fixedly installed at the midpoint of the lower end face of the lower fixing plate 207, and a support plate 6 is fixedly installed at the lower end of the midpoint of the front end face of the furnace body steel structure 1, with the lower end face of the fixing plate fixedly installed on the upper end face of the support plate 6.

[0030] Specifically, after the fixing rod 12 is fixedly installed on the lower end face of the lower fixing plate 207, it can play a supporting and fixing role for the connecting mechanism 2 after being connected with the support plate 6.

[0031] Reference Figure 4 The gas supply pipe 205 is fixedly embedded at the midpoint of the front end face of the furnace body steel structure 1, and multiple clamping pipes 202 can be clamped to multiple exhaust gas pipes.

[0032] Specifically, after the gas supply pipe 205 is embedded in the front end of the furnace steel structure 1, the exhaust gas transported by the exhaust gas pipeline through the clamping pipe 202 can be better discharged into the furnace steel structure 1 for re-combustion.

[0033] Reference Figure 2 The two connecting devices 9 are fixedly fitted with an upper sealing box 4 on the upper end face of the connecting device 9 located at the upper end, and the two connecting devices 9 are fixedly fitted with a lower sealing box 3 on the lower end face of the connecting device 9 located at the lower end.

[0034] Specifically, after the upper sealing box 4 or the lower sealing box 3 is snapped onto the upper or lower end face of the two connecting devices 9, the steel strip can be better inserted into the furnace steel structure 1 for combustion and heating.

[0035] Reference Figure 3 An exhaust pipe 5 is embedded and fixed at the midpoint of the rear end of the upper end face of the furnace body steel structure 1. The exhaust pipe 5 can be connected to the discharge pipe.

[0036] Specifically, after an exhaust pipe 5 is embedded in the upper end face of the furnace body steel structure 1, the gas can be discharged after combustion. After the exhaust pipe 5 is connected to the discharge pipe, the gas can be discharged more effectively.

[0037] Reference Figure 3 A gas transmission pipe 8 is embedded and fixed at the midpoint of the rear end face of the furnace body steel structure 1. One end of the gas transmission pipe 8 can be connected to the natural gas transmission pipeline of the furnace body steel structure 1.

[0038] Specifically, by embedding the gas transmission pipe 8, which is connected to the natural gas transmission pipeline, into the rear end face, natural gas can be better delivered to the furnace body steel structure 1 for use.

[0039] Working principle: During use, the operator can connect the natural gas transmission pipeline and the gas transmission pipe 8, and at the same time connect the waste gas pipeline and the clamping pipe 202 in the clamping steel strip. The steel strip can then be extended from the lower end face of the lower sealing box 3 into the furnace steel structure 1. The extended steel strip can also be extended from the upper sealing box 4. After starting the burner 10 set in the furnace steel structure 1, the natural gas can be ignited, so that the natural gas can be used to continue to burn and heat the steel strip. At the same time, the connecting mechanism 2 can discharge the waste gas generated in other processes into the furnace steel structure 1 for re-combustion, so as to better discharge the generated gas.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
