Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat utilization device for a glass microsphere forming furnace. Background Technology

[0002] In the manufacturing of glass microspheres, the bead-forming furnace requires a high-temperature environment to promote the formation of beads from the raw materials. The large amount of high-temperature flue gas generated by combustion contains considerable waste heat. Direct emission of this waste heat would cause energy waste and thermal pollution. Therefore, a waste heat utilization device for the glass microsphere bead-forming furnace is set up. This device is connected to the waste heat utilization components and other structures through the flue pipe to recover the waste heat of the flue gas, heat the air required for combustion to improve combustion efficiency and reduce fuel consumption, and at the same time reduce the flue gas temperature to reduce thermal pollution.

[0003] A search revealed Chinese Patent Publication No. CN215864707U, which discloses a waste heat utilization device for a glass microsphere forming furnace. The device includes a forming furnace, a flue gas connection pipe, an inlet connection pipe, and a heat exchange device. The waste heat from the exhaust gas generated by the forming furnace is transported to the heat exchange device through the flue gas connection pipe. The heat exchange gas of the heat exchange device is connected to the side of the forming furnace through the inlet connection pipe. The heat exchange device includes a shell, a primary heat exchange chamber, a secondary heat exchange chamber, and a heat exchange coil. The outlet pipe on the primary heat exchange chamber is connected to the forming furnace through the inlet connection pipe. The forming furnace is connected to the heat exchange coil through the flue gas connection pipe. This application's device uses a negative pressure principle to create an automatic dynamic balance in the sealed forming furnace during combustion, preventing additional heat loss due to the presence of a blower. The heat exchange device employs a two-stage heat exchange system, resulting in more thorough absorption of waste heat from the exhaust gas.

[0004] The aforementioned patent has the following shortcomings: due to the small inner diameter of the heat exchange tubes in the device, the narrow space inside the tubes and the tortuous channels, conventional cleaning tools are difficult to penetrate into the tubes. At the same time, the dust in the high-temperature flue gas easily adheres to the tube walls to form stubborn ash, making it difficult for staff to efficiently remove the dust inside the tubes. The long-term accumulation of dust will block the heat exchange tube channels and thicken the thermal resistance layer, which not only reduces the waste heat recovery efficiency but also increases the difficulty and cost of equipment maintenance.

[0005] To address this, a waste heat utilization device for glass microsphere forming furnaces is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide a waste heat utilization device for a glass microsphere forming furnace to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model embodiment is implemented as follows: A waste heat utilization device for a glass microsphere forming furnace includes a shell and further includes: A smoke inlet pipe is fixed to the top of the housing. An air inlet pipe is provided on one side of the housing, and an exhaust pipe is fixed on the other side of the housing. A smoke exhaust pipe is provided at the bottom of one side of the housing, and a support frame is fixed on the outside of the housing. A partition plate is fixed at the top of the shell, and a heat exchange tube is fixed between two adjacent sets of partition plates. A cleaning structure is provided at the top of the housing. The cleaning structure includes a storage shell fixed to the top of one side of the housing. A heat insulation plate is slidably connected to one side of the top of the storage shell. A connecting pipe is provided inside the storage shell. A high-pressure nozzle is fixed to the bottom of the connecting pipe. A high-pressure air pipe is fixed to the side of the connecting pipe. Movable components are provided on both sides of the connecting pipe. A dust removal structure for collecting and discharging dust that falls inside the shell is located at the bottom of the shell. A preheating structure for secondary heat recovery from exhaust gas is located at the bottom of one side of the shell.

[0008] In some embodiments: the intake pipe and the support frame are located on the same horizontal center line, and the partitions are symmetrically distributed on the horizontal center line of the intake pipe.

[0009] In some embodiments: the moving component includes a second moving frame fixed to one side of the connecting pipe, a lead screw threadedly connected to the second moving frame is rotatably connected to one side of the housing, a stepper motor with its output shaft end connected to the lead screw is installed on one side of the housing, a first moving frame is fixed to the other side of the connecting pipe, a guide rod fixedly connected to the housing is slidably connected inside the first moving frame, and a dust baffle fixedly connected to the housing is sleeved on the outer side of the guide rod and the top of the lead screw.

[0010] In some embodiments: the frontal cross-section of the second movable frame and the first movable frame is U-shaped, and the arrangement density of the high-pressure nozzles is adapted to the arrangement density of the heat exchange tubes.

[0011] In some embodiments: the ash discharge structure includes a connecting sleeve fixed to the bottom of the housing, an ash hopper fixed to the bottom of the connecting sleeve, an ash discharge shell fixed to the bottom of the ash hopper, an ash-discharging wheel rotatably connected inside the ash discharge shell, a drive motor installed on one side inside the support frame, a flexible coupling connected to the rotating end of the ash-discharging wheel fixed to the output shaft end of the drive motor, support springs connected to the support frame fixed to the bottom ends of both sides of the ash hopper, and an electromagnetic vibrator fixed to the side of the bottom end of the ash hopper.

[0012] In some embodiments: the frontal cross-section of the ash hopper has a funnel-shaped inclined structure, and the connecting sleeve is a retractable structure made of rubber.

[0013] In some embodiments: the preheating structure includes a first connecting shell fixed to the bottom of one side of the housing and connected to the exhaust pipe, a second connecting shell fixed to one side of the housing and connected to the air inlet pipe, an insulation block fixed between the second connecting shell and the first connecting shell, a heat pipe inserted inside the insulation block, a heat dissipation fin fixed to the top of the outer side of the heat pipe, and a heat conduction fin fixed to the bottom of the outer side of the heat pipe.

[0015] The present invention has the following advantages due to the adoption of the above technical solution: A waste heat recovery device for a glass microsphere forming furnace utilizes a stepper motor to drive a lead screw, which in turn moves a second moving frame, connecting pipes, and a high-pressure nozzle towards the heat exchange tubes. High-pressure gas is ejected from the nozzles to clean the heat exchange tubes, thus achieving the device's air-jet cleaning function. The high-pressure airflow rapidly impacts the interior of the heat exchange tubes, directly stripping away attached dust and ash. Cleaning can be completed without disassembling the equipment, effectively preventing dust from clogging pipes and thickening the thermal resistance layer, while reducing equipment downtime for maintenance. Furthermore, the device uses heat pipes and heat-conducting fins to absorb residual heat carried by the flue gas, which is then transferred to the air inside the second connecting shell via heat sinks. This achieves a secondary preheating function, utilizing the residual heat in the recovered flue gas to preheat the air entering the device, maximizing the utilization of waste heat and reducing energy waste. A waste heat utilization device for a glass microsphere forming furnace, by activating an electromagnetic vibrator to vibrate the ash hopper, prevents dust from adhering to the inner wall of the ash hopper, and simultaneously activates a drive motor to rotate an ash-discharging wheel, thus discharging the dust from the ash hopper. This achieves the dust discharge function of the device, centrally collecting dust inside the device for centralized treatment or recycling, reducing solid waste pollution. Vibration also improves the ash discharge efficiency and prevents dust from re-adhering. The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1: like Figures 1 to 6 As shown, a waste heat utilization device for a glass microsphere forming furnace includes a shell 1, and further includes: The smoke inlet pipe 7 is fixed to the top of the housing 1. An air inlet pipe 6 is provided on one side of the housing 1, and an exhaust pipe 8 is fixed on the other side of the housing 1. An exhaust pipe 4 is provided at the bottom of one side of the housing 1, and a support frame 2 is fixed on the outside of the housing 1. The partition 10 is fixed to the top of the shell 1, and heat exchange tubes 11 are fixed between two adjacent sets of partitions 10. The cleaning structure 9 is located at the top of the housing 1. The cleaning structure 9 includes a storage shell 902 fixed to the top of one side of the housing 1. A heat insulation plate 905 is slidably connected to one side of the top of the storage shell 902. A connecting pipe 903 is provided inside the storage shell 902. A high-pressure nozzle 904 is fixed to the bottom of the connecting pipe 903. A high-pressure air pipe 901 is fixed to the side of the connecting pipe 903. Movable components are provided on both sides of the connecting pipe 903. The ash discharge structure 3, which is used to collect the dust that falls inside the shell 1 and discharge it in a centralized manner, is set at the bottom of the shell 1; The preheating structure 5, used for secondary heat recovery from the exhaust gas, is located at the bottom of one side of the shell 1. The intake pipe 6 and the support frame 2 are located on the same horizontal center line, and the partition 10 is symmetrically distributed on the horizontal center line of the intake pipe 6.

[0028] In this embodiment, during use, the inlet pipe 7 is connected to the exhaust channel of the bead-forming furnace, and the exhaust pipe 8 is connected to the air inlet channel of the bead-forming furnace. The high-temperature flue gas generated by the bead-forming furnace enters the interior of the shell 1 through the inlet pipe 7. At the same time, outside air enters the shell 1 through the air inlet pipe 6. Then, the high-temperature flue gas enters the interior of the heat exchange tube 11 and exchanges heat with the air through the heat exchange tube 11. The air after heat exchange is discharged through the exhaust pipe 8 and enters the air inlet channel of the bead-forming furnace, which can be used as combustion air. The flue gas after preliminary cooling flows to the exhaust pipe 4. At the same time, the preheating structure 5 recovers the heat in the flue gas again and preheats the air entering the device.

[0029] like Figures 1 to 4 As shown: The moving component includes a second moving frame 910 fixed to one side of the connecting pipe 903. A lead screw 909, which is threadedly connected to the second moving frame 910, is rotatably connected to one side of the housing 1. A stepper motor 908, whose output shaft end is connected to the lead screw 909, is installed on one side of the housing 1. A first moving frame 907 is fixed to the other side of the connecting pipe 903. A guide rod 906, which is fixedly connected to the housing 1, is slidably connected inside the first moving frame 907. A dust baffle 911, which is fixedly connected to the housing 1, is sleeved on the outer side of the top of the guide rod 906 and the lead screw 909.

[0030] In this embodiment, when a large amount of soot adheres to the inner wall of the heat exchange tube 11, affecting the heat exchange efficiency, the housing 902 is opened by pulling the heat insulation plate 905. Then, the stepper motor 908 is started, driving the lead screw 909 to rotate. The lead screw 909, through thread engagement, moves the second moving frame 910. The second moving frame 910 then moves the connecting pipe 903, causing the high-pressure nozzle 904 to move towards and align with the heat exchange tube 11. Simultaneously, the connecting pipe 903 drives the first moving frame 907 to slide along the guide rod 906, guiding the movement of the connecting pipe 903 and connecting the high-pressure gas pipe 901 to the high-pressure gas pump. The connection is made so that high-pressure gas is delivered to the connecting pipe 903 through the high-pressure gas pipe 901. The high-pressure gas is sprayed out through the high-pressure nozzle 904. The high-pressure airflow is used to peel off the dust from the inner wall of the heat exchange tube 11, achieving a cleaning effect. After cleaning, the stepper motor 908 drives the connecting pipe 903 to reset, and then the sliding heat insulation plate 905 blocks the opening of the housing shell 902, which to a certain extent ensures the cleanliness of the inner wall of the heat exchange tube 11 and maintains the heat exchange efficiency of the heat exchange tube 11. At the same time, it avoids the dust from affecting other components of the device during the cleaning process. The dust baffle 911 can directly prevent the falling dust from contacting the lead screw 909 and guide rod 906.

[0031] like Figures 1 to 4 As shown: the frontal cross-section of the second movable frame 910 and the first movable frame 907 is U-shaped, and the arrangement density of the high-pressure nozzles 904 is matched with the arrangement density of the heat exchange tubes 11.

[0032] In this embodiment, the second movable frame 910 works in conjunction with the first movable frame 907 to use the dust baffle 911 to prevent falling smoke and dust from contacting the lead screw 909 and guide rod 906. The arrangement density of the high-pressure nozzles 904 is adapted to the heat exchange tubes 11, so that each high-pressure nozzle 904 corresponds to a set of heat exchange tubes 11, ensuring that the inner wall of the heat exchange tubes 11 can be fully covered during air jet cleaning, thereby improving the cleaning effect.

[0033] Example 2: A waste heat utilization device for a glass microsphere forming furnace, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 6 As shown, the ash discharge structure 3 includes a connecting sleeve 306 fixed to the bottom of the housing 1, an ash hopper 301 fixed to the bottom of the connecting sleeve 306, an ash discharge shell 302 fixed to the bottom of the ash hopper 301, an ash-discharging wheel 303 rotatably connected inside the ash discharge shell 302, a drive motor 307 installed on one side inside the support frame 2, a flexible coupling 308 connected to the rotating end of the ash-discharging wheel 303 fixed to the output shaft end of the drive motor 307, support springs 305 connected to the support frame 2 fixed to the bottom ends on both sides of the ash hopper 301, and an electromagnetic vibrator 304 fixed to the side of the bottom end of the ash hopper 301.

[0034] In this embodiment, when the dust falls to the bottom of the housing 1, the electromagnetic vibrator 304 is activated, which drives the ash hopper 301 to vibrate. At the same time, the support spring 305 extends and retracts during the vibration of the ash hopper 301, assisting the vibration of the ash hopper 301 and preventing the dust from sticking to the inner wall of the ash hopper 301. Simultaneously, the drive motor 307 is activated, and the output shaft of the drive motor 307 drives the dust-discharging wheel 303 to rotate through the flexible coupling 308. The dust-discharging wheel 303 rotates to transport the dust in the ash hopper 301 to the ash discharge shell 302 and discharge it. The connecting sleeve 306 can adapt to the vibration of the ash hopper 301, preventing the dust from leaking from the connection between the ash hopper 301 and the housing 1. To a certain extent, this achieves efficient collection and discharge of dust, prevents dust from accumulating inside the housing 1 and affecting the operation of the device, and reduces the workload of manual dust cleaning.

[0035] like Figures 1 to 6 As shown: The frontal cross-section of the ash hopper 301 has a funnel-shaped inclined structure, and the connecting sleeve 306 is a retractable structure made of rubber.

[0036] In this embodiment, the ash hopper 301 utilizes the guiding effect of the inclined surface to allow the dust falling from the shell 1 to quickly converge to the bottom of the ash hopper 301 along the inclined surface, thus preventing the dust from accumulating inside the ash hopper 301. The connecting sleeve 306 can flexibly deform with the vibration of the ash hopper 301, ensuring the sealing of the connection between the ash hopper 301 and the shell 1 without affecting the vibration and ash discharge action of the ash hopper 301.

[0037] like Figures 2 to 5As shown: The preheating structure 5 includes a first connecting shell 501 fixed to the bottom of one side of the housing 1 and connected to the exhaust pipe 4. A second connecting shell 504 connected to the air inlet pipe 6 is fixed to one side of the housing 1. A heat insulation block 502 is fixed between the second connecting shell 504 and the first connecting shell 501. A heat pipe 503 is inserted inside the heat insulation block 502. A heat dissipation fin 505 is fixed to the top of the outside of the heat pipe 503. A heat conduction fin 506 is fixed to the bottom of the outside of the heat pipe 503.

[0038] In this embodiment, when the flue gas, after initial cooling, enters the first connecting shell 501, the residual heat carried by the flue gas is transferred to the heat-conducting plate 506. The heat-conducting plate 506 transfers the heat to the heat pipe 503, and the heat pipe 503 conducts the heat to the heat sink 505 at the top. At the same time, the air delivered by the air inlet pipe 6 enters the second connecting shell 504. The heat sink 505 transfers the heat to the air inside the second connecting shell 504, preheating the air a second time. The insulation block 502 can reduce the heat loss from the heat pipe 503. The preheated air then enters the shell 1 to participate in subsequent heat exchange, which to a certain extent realizes the secondary recovery and utilization of the waste heat of the flue gas, improves the energy utilization rate, and at the same time reduces the temperature of the final discharged flue gas, reducing thermal pollution.

[0039] like Figures 2 to 5 As shown: the top end of the heat pipe 503 extends into the interior of the second connecting shell 504, the bottom end of the heat pipe 503 extends into the interior of the first connecting shell 501, and the heat-conducting plates 506 are arranged at equal intervals on the outer side wall of the heat pipe 503.

[0040] In this embodiment, the heat pipe 503 can directly contact the flue gas inside the first connecting shell 504 and the air inside the second connecting shell 504, shortening the heat transfer path. The heat-conducting plates 506 are arranged at equal intervals on the outer wall of the heat pipe 503, which can increase the contact area between the heat pipe 503 and the flue gas and improve the heat absorption efficiency.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
