Description

Technical Field

[0001] The utility model belongs to the technical field of glass processing, in particular to an adjustable tuyere structure for controlling the temperature of a glass product kiln. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It uses quartz sand, soda ash, feldspar and limestone as raw materials. After mixing, high-temperature melting, homogenization, processing and forming, and then annealing, it is divided into quartz glass, silicate glass, soda-lime glass, fluoride glass, high-temperature glass, high-pressure resistant glass, UV-proof glass, explosion-proof glass, etc. It is widely used in architecture, daily necessities, art, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and other fields. When the glass is melted at high temperature in the kiln, air needs to be injected into the kiln through the tuyere structure to control the temperature in the kiln to avoid excessive temperature in the kiln and ensure the stability of glass processing. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN217265401U discloses an adjustable air inlet structure for controlling the temperature of a glass product kiln, comprising an exhaust fan, the exhaust fan being fixedly mounted on the air inlet pipe; a telescopic member, the telescopic member being fixedly mounted on the air inlet pipe; an adjusting sleeve, the adjusting sleeve being fixedly mounted on the shaft end of the telescopic member, and the adjusting sleeve being slidably mounted in the air inlet pipe; a limiting column, the limiting column being fixedly mounted on the air inlet pipe through a fixing rod. Although the air inlet structure can inject cold air into the kiln to prevent the temperature in the kiln from being too high, when there is no need to inject air into the kiln, the surface temperature of the air inlet structure connected to the kiln tends to rise rapidly due to the influence of the kiln temperature, causing the exhaust fan in the air inlet pipe to be at a high temperature for a long time, thereby shortening the service life of the exhaust fan.

[0004] In order to prevent dust in the outside air from entering the kiln through the tuyere structure and causing pollution to the glass raw materials, a filter is usually set up in the tuyere structure. However, the setting of the filter often requires a cleaning mechanism to clean the filter to avoid clogging of the filter and causing a decrease in air volume. However, the cleaning mechanism will increase the cost and maintenance expenses of the tuyere structure. Utility Model Content

[0005] The purpose of the present utility model is to provide an adjustable tuyere structure for controlling the temperature of a glass product kiln. Through an air volume regulating tube, a temperature regulating tube and a driving tube, the problem that the temperature of the tuyere structure is affected by the temperature in the kiln when the tuyere structure is not in use, causing the exhaust fan to be at high temperature for a long time and shortening the service life of the exhaust fan is solved, the tuyere structure is usually provided with a filter, but the setting of the filter often leads to the need to set a cleaning mechanism for the tuyere structure to clean the filter to avoid clogging of the filter and causing a decrease in air volume, but the cleaning mechanism will increase the cost and maintenance expenses of the tuyere structure.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model discloses an adjustable air inlet structure for controlling the temperature of a glass product furnace, comprising an air volume regulating tube, a temperature regulating tube and a driving tube. A control frame is fixedly connected in the air volume regulating tube, and heat-insulating rotating plates are rotatably connected at both ends of one side of the control frame. A temperature regulating tube is fixedly connected in one end of the air volume regulating tube, a refrigeration component is fixedly connected in the outer peripheral surface of the temperature regulating tube, a driving tube is connected in one end of the temperature regulating tube, an exhaust fan is connected in the driving tube, and a plurality of air pressure valves are connected in the outer peripheral surface of the driving tube.

[0008] A rotating motor is provided in the control frame, which can drive the rotation of the heat preservation rotating plate. The air volume entering the kiln can be further adjusted by the rotation angle. When there is no need to inject air into the kiln, the closing of the heat preservation rotating plate can prevent heat from being lost through the air outlet structure. At the same time, the heat preservation effect of the heat preservation rotating plate prevents heat from being quickly transferred to the surface of the air outlet structure. The temperature regulating tube can be cooled by the refrigeration component to prevent the air volume regulating tube from being affected by the temperature in the kiln and heating up. The temperature is transferred to the surface of the exhaust fan to prevent the exhaust fan from being at high temperature for a long time. The refrigeration component can The air passing through the temperature regulating tube is cooled, and the temperature control efficiency of the air outlet structure in the kiln is further improved. The exhaust fan can drive the flow of air, so that cold air enters the kiln to adjust the temperature inside the kiln. At the same time, the flow of air reduces the air pressure in the driving tube, so that the outside air enters the driving tube through the air pressure valve under the action of air pressure to replenish the air. When the dust screen needs to be cleaned, the exhaust fan is reversed to allow the outside air to enter the driving tube through the air pressure valve, and then it is cleaned through the dust screen. There is no need to set up an additional cleaning structure, which reduces costs and maintenance expenses.

[0009] Furthermore, a mounting plate is welded and fixed to one end of the outer circumference of the air volume regulating tube, and the mounting plate is located at the other end of the air volume regulating tube relative to the temperature regulating tube. A support rod is clamped and fixed to one side of the control frame, and a temperature sensor assembly is clamped and fixed to the other end of the support rod. The support rod is located on the other side of the control frame relative to the temperature regulating tube.

[0010] The temperature inside the kiln can be monitored through the temperature sensing component, and the rotation of the heat-insulating rotating plate can be timely controlled by the control frame according to the temperature inside the kiln, so that outside air can enter the kiln and the temperature inside the kiln can be adjusted. The air volume entering the kiln can be further adjusted by rotating the heat-insulating rotating plate at different angles. When there is no need to inject air into the kiln, the closing of the heat-insulating rotating plate can prevent heat from being lost through the tuyere structure. At the same time, the heat-insulating effect of the heat-insulating rotating plate prevents heat from being quickly transferred to the surface of the tuyere structure.

[0011] Furthermore, a plurality of heat-conducting fins are fixedly connected to the inner wall of the temperature regulating tube, a control assembly is fixedly connected to the outer side of the refrigeration assembly, and the temperature regulating tube is located between the air volume regulating tube and the driving tube;

[0012] The refrigeration component can cool the temperature regulating tube to prevent the air volume regulating tube from being affected by the temperature in the kiln and heating up. The temperature is transferred to the surface of the exhaust fan to prevent the exhaust fan from being at a high temperature for a long time. The refrigeration component can also cool the air passing through the temperature regulating tube. The heat conduction area of the temperature regulating tube can be increased through multiple heat conducting fins, and the air passing through the temperature regulating tube can be quickly cooled, further improving the efficiency of the air outlet structure in regulating the temperature in the kiln.

[0013] Furthermore, a thread groove is formed on one end of the outer circumference of the driving tube, the thread groove is located at the other end of the driving tube opposite to the temperature regulating tube, and the air pressure valve is located between the temperature regulating tube and the exhaust fan;

[0014] The exhaust fan can drive the flow of air, allowing cold air to enter the kiln to adjust the temperature inside the kiln and prevent the temperature inside the kiln from being too high. At the same time, the flow of air reduces the air pressure in the drive pipe, allowing outside air to enter the drive pipe through the air pressure valve under the action of air pressure to replenish the air.

[0015] Furthermore, a dustproof threaded tube is screwed and fixed on the outer circumference of the threaded groove, a dustproof net is clamped and fixed on one end of the dustproof threaded tube, and the dustproof net is attached to one end of the driving tube;

[0016] When the exhaust fan drives the flow of air, the dust screen can prevent dust from entering the kiln and preventing dust from contaminating the glass raw materials. When the dust screen needs to be cleaned, the exhaust fan is controlled to reverse so that the outside air enters the drive pipe through the air pressure valve, and then cleaned through the dust screen. There is no need to set up an additional cleaning structure, which reduces costs and maintenance expenses. A filter can be set in the air pressure valve to prevent dust in the air from entering the drive pipe through the air pressure valve. By closing the insulation rotating plate and then controlling the forward rotation of the exhaust fan, the air flow can be discharged through the air pressure valve to clean the filter in the air pressure valve.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that although cold air can be injected into the kiln through the tuyere structure to avoid excessive temperature in the kiln, when there is no need to inject air into the kiln, the surface temperature of the tuyere structure connected to the kiln tends to rise rapidly due to the influence of the kiln temperature, causing the exhaust fan in the air inlet pipe to be at high temperature for a long time, thereby shortening the service life of the exhaust fan, by arranging an air volume regulating tube and a temperature regulating tube. When there is no need to adjust the temperature in the kiln, the control frame controls the heat preservation rotating plate to rotate and close, and the refrigeration component cools the temperature regulating tube to avoid the air volume regulating tube being affected by the temperature in the kiln and heating up, and the temperature is transferred to the surface of the exhaust fan to avoid the exhaust fan being at high temperature for a long time.

[0019] The utility model solves the problem that in order to prevent dust in the outside air from entering the kiln through the air vent structure and causing pollution to the glass raw materials, the air vent structure is usually provided with a filter, but the provision of the filter often leads to the need to provide a cleaning mechanism for the air vent structure to clean the filter to prevent the filter from being blocked and causing a decrease in air volume, but the cleaning mechanism will increase the cost and maintenance expenses of the air vent structure. When the temperature in the kiln is lowered, the exhaust fan drives the flow of air, and the dustproof net prevents dust from entering the kiln. At the same time, the flow of air reduces the air pressure in the driving pipe, so that the outside air enters the driving pipe through the air pressure valve under the action of the air pressure to replenish the air. When the dustproof net needs to be cleaned, the exhaust fan is controlled to reverse to allow the outside air to enter the driving pipe through the air pressure valve, and then it is cleaned through the dustproof net. There is no need to provide an additional cleaning structure, thereby reducing costs and maintenance expenses. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-5 As shown, the utility model is an adjustable air inlet structure for controlling the temperature of a glass product furnace, comprising an air volume regulating tube 1, a temperature regulating tube 2 and a drive tube 3. A control frame 102 is fixedly connected to the air volume regulating tube 1, and heat-insulating rotating plates 103 are rotatably connected to both ends of one side of the control frame 102. One end of the air volume regulating tube 1 is fixedly connected to the temperature regulating tube 2, and a refrigeration component 201 is fixedly connected to the outer peripheral surface of the temperature regulating tube 2. One end of the temperature regulating tube 2 is fixedly connected to the drive tube 3, and an exhaust fan 303 is connected to the inner portion of the drive tube 3. A plurality of air pressure valves 304 are connected to the outer peripheral surface of the drive tube 3.

[0029] The air outlet structure is connected to the kiln through the mounting plate 101. When the kiln is in use, the refrigeration component 201 is started to cool the temperature regulating tube 2 to prevent the temperature inside the kiln from affecting the exhaust fan 303. When the temperature sensing component 105 detects that the kiln needs to be cooled, the control frame 102 controls the heat preservation rotating plate 103 to rotate and open, and adjusts the rotation angle according to the temperature inside the kiln, and further adjusts the air volume. The exhaust fan 303 drives the air flow, so that the outside air enters the drive tube 3 through the dustproof net 305. The air cools down rapidly when passing through the temperature regulating tube 2 and cools the inside of the kiln. When the temperature inside the kiln drops to a specified value, the heat preservation rotating plate 103 is closed, and the exhaust fan 303 is controlled to reverse, so that the outside air enters the drive tube 3 through the air pressure valve 304, and then is discharged through the dustproof net 305 to clean the dustproof net 305.

[0030] Among them Figure 1-3 As shown, a mounting plate 101 is welded and fixed to one end of the outer circumference of the air volume regulating tube 1. The mounting plate 101 is located at the other end of the air volume regulating tube 1 relative to the temperature regulating tube 2. A support rod 104 is fixed to one side of the control frame 102. A temperature sensor assembly 105 is fixed to the other end of the support rod 104. The support rod 104 is located on the other side of the control frame 102 relative to the temperature regulating tube 2.

[0031] The tuyere structure and the kiln are installed and connected through the mounting plate 101. When the kiln is in use, the temperature sensing component 105 monitors the temperature inside the kiln and controls the rotation and opening of the heat-insulating rotating plate 103 in time through the control frame 102 according to the temperature inside the kiln. The rotation angle of the heat-insulating rotating plate 103 is controlled according to the required air volume. When there is no need to inject air into the kiln, the heat-insulating rotating plate 103 is closed to prevent heat from being lost through the tuyere structure.

[0032] Among them Figure 1 、 4 As shown, a plurality of heat-conducting fins 203 are fixed to the inner wall of the temperature regulating tube 2, a control assembly 202 is fixed to the outer side of the refrigeration assembly 201, and the temperature regulating tube 2 is located between the air volume regulating tube 1 and the driving tube 3;

[0033] The refrigeration temperature of the refrigeration component 201 is controlled by the control component 202. The refrigeration component 201 cools down the temperature regulating tube 2 to prevent the air volume regulating tube 1 from being affected by the temperature in the kiln and heating up. The temperature is transferred to the surface of the exhaust fan 303 to prevent the exhaust fan 303 from being at a high temperature for a long time. The heat conduction area of the temperature regulating tube 2 is increased by the multiple heat conduction fins 203. When the refrigeration component 201 cools down the temperature regulating tube 2, it also cools down the multiple heat conduction fins 203, so that the air passing through the temperature regulating tube 2 is quickly cooled.

[0034] Among them Figure 1 、 5 As shown, a thread groove 302 is formed on one end of the outer circumference of the driving tube 3. The thread groove 302 is located at the other end of the driving tube 3 relative to the temperature regulating tube 2. The air pressure valve 304 is located between the temperature regulating tube 2 and the exhaust fan 303. A dustproof threaded tube 301 is screwed and fixed on the outer circumference of the thread groove 302. A dustproof net 305 is clamped and fixed on one end of the dustproof threaded tube 301. The dustproof net 305 is attached to one end of the driving tube 3.

[0035] When adjusting the temperature in the kiln, the exhaust fan 303 drives the flow of air, so that the cold air passes through the dustproof net 305 for filtration and enters the kiln to adjust the temperature in the kiln. At the same time, the fast-flowing air causes the driving pipe 3 to be at a low pressure, so that the outside air enters the driving pipe 3 through the air pressure valve 304 under the action of air pressure, and further supplements the air entering the air inlet structure. When the dustproof net 305 needs to be cleaned, the exhaust fan 303 is controlled to reverse so that the outside air enters the driving pipe 3 through the air pressure valve 304, and then is cleaned through the dustproof net 305.

[0036] The specific working principle of the present invention is as follows: the tuyere structure and the kiln are installed and connected through the mounting plate 101. When the kiln is in use, the refrigeration temperature of the refrigeration component 201 is controlled by the control component 202. The temperature sensor component 105 monitors the temperature inside the kiln and controls the rotation and opening of the heat preservation rotating plate 103 in time according to the temperature inside the kiln through the control frame 102. The rotation angle of the heat preservation rotating plate 103 is controlled according to the required air volume. The exhaust fan 303 drives the flow of air, so that the cold air is filtered through the dustproof net 305. At the same time, the fast-flowing air makes the driving pipe 3 at a low pressure, so that the outside air enters the driving pipe 3 through the air pressure valve 304 under the action of the air pressure, and the air entering the tuyere structure is cooled. The air is further replenished, the refrigeration component 201 cools the temperature regulating tube 2, quickly cools the air passing through the temperature regulating tube 2, and the cold air enters the kiln through the air volume regulating tube 1 to cool the kiln. When there is no need to inject air into the kiln, the heat preservation rotating plate 103 is closed to prevent heat from being lost through the air outlet structure. At the same time, the refrigeration component 201 cools the temperature regulating tube 2 to prevent the air volume regulating tube 1 from being affected by the temperature in the kiln and heating up. The temperature is transferred to the surface of the exhaust fan 303 to prevent the exhaust fan 303 from being at high temperature for a long time. The exhaust fan 303 is reversed to allow the outside air to enter the drive pipe 3 through the air pressure valve 304, and then cleaned through the dustproof net 305.

[0037] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
