Description

Technical Field

[0001] The present disclosure relates to the technical field of glass production and manufacturing, and particularly relates to a pressure stabilizing device for a dust cleaning port of a kiln flue and a glass kiln. Background Art

[0002] A dust cleaning port is installed at the bottom of the smoke exhaust pipeline of a glass kiln. During the process that the flue gas in the glass kiln enters the dust storage through the flue, heavier particulate matters and some condensates in the flue gas will deposit at the bottom of the flue. In the long run, it will inevitably cause blockage of the flue and affect the smoke exhaust efficiency of the glass kiln.

[0003] During normal production, it is necessary to regularly clean the flue through the dust cleaning port. When the dust cleaning port is opened, it will cause fluctuations in the pressure inside the kiln, which has a great impact on the product quality. Therefore, it is necessary to perform air make-up operation on the glass kiln to maintain the stability of the kiln pressure.

[0004] Among them, the patent document (CN 220887316 U) provides a dust cleaning constant pressure device for a flue of a glass kiln and a glass kiln. A sealed operation room is arranged outside the dust cleaning port of the flue, and the sealed operation room is supplied with air through an air make-up mechanism to keep the internal and external pressures at the dust cleaning port of the flue the same, achieving the purpose of maintaining the stability of the kiln pressure.

[0005] However, since the sealed operation room is an independent space outside the flue, it has its own independent air make-up port and smoke exhaust port, resulting in difficulty in making the wind directions inside the sealed operation room and inside the flue consistent. During dust cleaning, it is easy to cause chaotic air flow directions at the position of the dust cleaning port of the flue, making it difficult for the staff to clean the dust and resulting in incomplete dust cleaning.

[0008] In some embodiments, a pressurizing port for docking with the variable frequency fan is provided on the top wall of the flue, and the wind guiding plate is arranged inside the flue and at the pressurizing port.

[0012] In some embodiments, a door shaft is arranged on one side of the ash baffle, and the driving mechanism can drive the ash baffle to rotate around the door shaft to adjust the opening size of the ash cleaning door.

[0013] In some embodiments, a plurality of hinges are arranged on the door shaft. The hinge includes a first blade fixed to the outer wall of the flue and a second blade fixed to the ash baffle.

[0014] In some embodiments, the driving mechanism includes a driver arranged on the outer wall of the flue, a driving gear coaxially connected to the driver, and a driven gear sleeved on the door shaft and meshing with the driving gear.

[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0031] As Figure 1 and Figure 2 shown, the present disclosure provides a pressure stabilizing device for a soot cleaning port of a kiln flue, including: a flue 1, on the side wall of the flue 1, there is an openable and closable soot cleaning door 2; a variable frequency fan 3, the variable frequency fan 3 is located upstream of the soot cleaning door 2 along the smoke exhaust direction, the variable frequency fan 3 is communicated with the flue 1, and the variable frequency fan 3 can change the magnitude of the air volume introduced into the flue 1 by itself; a wind guiding plate 4, the wind guiding plate 4 is used to guide the air flow direction of the variable frequency fan 3 so that the air flow direction of the variable frequency fan 3 is the same as the air flow direction in the flue 1; and a pressure sensor 5, the pressure sensor 5 is located downstream of the soot cleaning door 2 along the smoke exhaust direction, and is used to monitor the air pressure change in the flue 1.

[0032] Specifically, since the ash 7 is usually deposited at the bottom of the flue 1, the ash cleaning door 2 is arranged on the side wall adjacent to the bottom of the flue 1, so that the staff can clean the ash 7. The variable frequency fan 3 is used to introduce airflow into the flue 1. After the airflow introduced into the flue 1 by the variable frequency fan 3 passes through the air guide plate 4, its flow direction is consistent with the exhaust direction of the smoke inside the flue 1. When the cleaning door 2 is closed, the variable frequency fan 3 operates at a lower power to assist the flue gas discharge in the flue 1. At this time, the air pressure measured by the pressure sensor 5 is the initial air pressure inside the flue 1. When the cleaning door 2 is opened, due to the leakage of part of the airflow to the outside of the flue 1 at the cleaning door 2, the air pressure measured by the pressure sensor 5 decreases. At this time, by increasing the operating power of the variable frequency fan 3, the air volume entering the flue 1 is increased, and the air volume leaked from the cleaning door 2 is supplemented, so that the air pressure measured by the pressure sensor 5 is restored to the initial air pressure, and the pressure inside the flue 1 and the kiln connected to the flue 1 is kept stable. At the same time, the guiding effect of the air guide plate 4 makes the wind direction of the variable frequency fan 3 entering the flue 1 consistent with the exhaust direction inside the flue 1. When the staff opens the cleaning door 2, even if the operating power of the variable frequency fan 3 changes, the airflow direction at the cleaning door 2 remains stable, which is conducive to the staff to thoroughly remove the accumulated dust 7.

[0033] like Figure 2 As shown, in some embodiments, the top wall of the flue 1 is provided with a boost port 101 connected to the variable frequency fan 3 , and the air guide plate 4 is arranged inside the flue 1 and located at the boost port 101 .

[0034] Specifically, the boost port 101 of the flue 1 is arranged at the upstream position of the cleaning door 2 along the smoke exhaust direction, and the variable frequency fan 3 introduces airflow into the interior of the flue 1 through the boost port 101. The airflow entering the flue 1 is adjusted to have its direction consistent with the smoke exhaust direction inside the flue 1 with the help of the air guide plate 4 arranged at the boost port 101 inside the flue 1, thereby avoiding that when the frequency of the variable frequency fan 3 changes, the airflow direction inside the flue 1 will also change, thereby affecting the cleaning operation of the staff.

[0035] like Figure 2 As shown, in some embodiments, the air guide plate 4 is an arc-shaped plate, and the tangential direction of the first end of the air guide plate 4 connected to the boost port 101 is parallel to the air inlet direction of the variable frequency fan 3, and the tangential direction of the second end of the air guide plate 4 is parallel to the smoke exhaust direction of the flue 1.

[0036] Specifically, to prevent the air deflector 4 from causing a sudden change in the air flow direction when guiding the air flow of the variable-frequency fan 3 into the flue 1, resulting in chaotic air flow direction inside the flue 1, the air deflector 4 is set as an arc-shaped plate that smoothly transitions along the guiding air flow direction. Moreover, the tangent direction of the first end of the air deflector 4 connected to the pressurizing port 101 is parallel to the air inlet direction of the variable-frequency fan 3, avoiding conflict with the air flow of the variable-frequency fan 3 entering the flue 1 and better receiving the air flow from the variable-frequency fan 3. At the same time, the tangent direction of the second end of the air deflector 4 is parallel to the smoke exhaust direction of the flue 1, so that the air flow from the variable-frequency fan 3, after being smoothly guided by the air deflector 4, is consistent with the smoke exhaust direction inside the flue 1, which is conducive to maintaining a stable air flow direction inside the flue 1 and facilitating the ash cleaning operation for the staff.

[0037] As Figure 1 and Figure 3 shown, in some embodiments, it further includes a driving mechanism 6, and the driving mechanism 6 is used to drive the opening and closing of the ash cleaning door 2. Specifically, since there is a certain wind pressure inside the flue 1, when opening the ash cleaning door 2, the ash cleaning door 2 will be quickly pushed open under the action of the wind pressure. If not careful, it is easy to cause harm to the operator. Using the driving mechanism 6 to drive the opening and closing of the ash cleaning door 2 avoids manual opening and closing and improves the safety of the ash cleaning operation.

[0038] In some embodiments, the opening speed and the opening and closing size of the ash cleaning door 2 can be controlled by the driving mechanism 6. The wind pressure downstream of the ash cleaning door 2 is measured by the pressure sensor 5 inside the flue 1, and the ash cleaning door 2 is slowly opened through the driving mechanism 6. At the same time, in cooperation with the reading of the pressure sensor 5, the operating power of the variable-frequency fan 3 is gradually increased, which is beneficial to reducing the impact of the ash cleaning operation on the pressure inside the flue 1 and the kiln.

[0039] In some embodiments, a controller communicatively connected to the variable-frequency fan 3, the driving mechanism 6, and the pressure sensor 5 can be set. The controller reads the measured value of the pressure sensor 5 in real time, and at the same time controls the air volume entering the flue 1 and the opening and closing size of the ash cleaning door 2 through the variable-frequency fan 3 and the driving mechanism 6, more precisely maintaining the stability of the pressure inside the flue 1 and the kiln. Compared with manual operation, it further reduces the impact of the ash cleaning operation on the pressure inside the flue 1 and the kiln. Here, the controller can be a common controller such as a programmable logic controller (PLC), a general-purpose processor, and a special-purpose processor, all of which can achieve the above purposes.

[0040] As Figure 1 and Figure 3 shown, in some embodiments, the ash cleaning door 2 includes a dust baffle 201 and a dust-proof seal ring 202 provided at at least part of the edge of the dust baffle 201. The dust baffle 201 can move under the drive of the driving mechanism 6 to open the ash cleaning door 2.

[0041] Specifically, since the ash cleaning door 2 can open and close relative to the side wall of the flue 1, to prevent leakage at the joint between the ash cleaning door 2 and the flue 1, the ash cleaning door 2 includes an ash baffle 201 and an ash sealing ring 202. Among them, the ash sealing ring 202 is fixedly sealed on the side wall of the flue 1, and the ash baffle 201 can be sealingly connected to the ash sealing ring 202. When the ash cleaning door 2 is in the closed state, the ash baffle 201 and the ash sealing ring 202 are sealingly connected to prevent flue gas from leaking out from the ash cleaning door 2. When ash cleaning operation is required, the driving mechanism 6 drives the ash baffle 201 to move to open the ash cleaning door 2.

[0042] As Figure 3 shown, in some embodiments, a door shaft 203 is provided on one side of the ash baffle 201, and the driving mechanism 6 can drive the ash baffle 201 to rotate around the door shaft 203 to adjust the opening size of the ash cleaning door 2.

[0043] Specifically, the driving mechanism 6 can control the angle of the ash baffle 201 rotating around the door shaft 203 to control the opening size of the ash cleaning door 2. During the ash cleaning process, when the air pressure inside the flue 1 is less than the initial air pressure when no ash cleaning is carried out, the driving mechanism 6 controls the ash baffle 201 to move towards the outer wall of the flue 1 around the door shaft 203 to reduce the opening area of the ash cleaning door 2. At the same time, the staff increases the operating power of the variable frequency fan 3 so that the air pressure inside the flue 1 is increased and restored to the initial air pressure; when the air pressure inside the flue 1 is greater than the air pressure when no ash cleaning is carried out, the driving mechanism 6 controls the ash baffle 201 to move away from the outer wall of the flue 1 around the door shaft 203 to increase the opening area of the ash cleaning door 2. At the same time, the staff reduces the operating power of the variable frequency fan 3 so that the air pressure inside the flue 1 drops and is restored to the initial air pressure. Of course, during the ash cleaning process, when the change in the air pressure inside the flue 1 relative to the initial air pressure is small, the air pressure inside the flue 1 can also be restored to the initial air pressure when no ash cleaning is carried out by separately controlling the opening area of the ash cleaning door 2 or the operating power of the variable frequency fan 3.

[0044] In some embodiments, corresponding sliders and guide rails can also be provided on the ash baffle 201 and the side wall of the flue 1, so that the ash baffle 201 can translate under the drive of the driving mechanism 6 to open the ash cleaning door 2.

[0045] As Figure 3 shown, in some embodiments, a plurality of hinges 204 are provided on the door shaft 203. The hinge 204 includes a first blade 2041 fixed to the outer wall of the flue 1 and a second blade 2042 fixed to the ash baffle 201.

[0046] Specifically, the door shaft 203 is connected to the outer wall of the flue 1 through the first leaf 2041 of the hinge 204, and is connected to the ash baffle 201 through the second leaf 2042 of the hinge 204. The ash baffle 201 can move around the door shaft 203 by means of the hinge 204. At the same time, to ensure the stability of the ash baffle 201 when rotating around the door shaft 203, a plurality of hinges 204 are distributed along the length direction of the door shaft 203.

[0047] As Figure 3 shown, in some embodiments, the driving mechanism 6 includes a driver 601 provided on the outer wall of the flue 1, a driving gear 602 coaxially connected to the driver 601, and a driven gear 603 sleeved on the door shaft 203 and meshing with the driving gear 602.

[0048] Specifically, the driver 601 controls the rotation of the driving gear 602 coaxially connected thereto. The driven gear 603 sleeved on the door shaft 203 meshes with the driving gear 602, so that the door shaft 203 rotates under the drive of the driver 601, driving the first leaf 2041 and the second leaf 2042 of the hinge 204 to move relative to each other, thereby controlling the movement of the ash baffle 201 relative to the outer wall of the flue 1, and achieving the purpose of adjusting the opening and closing size of the ash cleaning door 2.

[0049] As Figure 1 shown, in some embodiments, a plurality of ash cleaning doors 2 are provided on the flue 1, and the plurality of ash cleaning doors 2 are distributed along the smoke exhaust direction. Since in actual operation, the accumulated ash 7 will deposit at the bottom of the flue 1 along the smoke exhaust direction, therefore, arranging a plurality of ash cleaning doors 2 on the side wall of the flue 1 along the smoke exhaust direction is beneficial for the staff to more thoroughly remove the accumulated ash 7 inside the flue 1.

[0050] The present disclosure also provides a glass furnace, and this glass furnace includes the above-mentioned kiln furnace flue ash cleaning port pressure stabilizing device. Specifically, when the flue gas generated by the operation of the furnace is discharged outward along the flue 1, the heavier particulate matters and some condensates in the flue gas will deposit at the bottom of the flue 1, and it is necessary to clean the accumulated ash 7 through the ash cleaning door 2 on the flue 1. By means of the variable frequency blower 3 and the air deflector 4 provided upstream of the ash cleaning door 2 and the pressure sensor 5 provided downstream of the ash cleaning door 2, during the ash cleaning operation, the operating power of the variable frequency blower 3 is increased to increase the airflow entering the flue 1 to supplement the airflow lost at the ash cleaning door 2, and by observing the change of the reading of the pressure sensor 5, the operating power of the variable frequency blower 3 and the opening and closing size of the ash cleaning door 2 are adjusted to better maintain the pressure stability inside the glass furnace. At the same time, with the help of the air deflector 4, the airflow direction introduced into the flue 1 by the variable frequency blower 3 is kept consistent with the smoke exhaust direction inside the flue 1, making the airflow inside the flue 1 more stable, which is beneficial for the staff to carry out the ash cleaning operation.
