Description

Technical Field

[0001] The present disclosure relates to the technical field of glass production equipment, and particularly to a furnace observation device and a furnace having the same. Background Art

[0002] In the industrial production process of glass, a glass furnace is usually used to heat production raw materials to melt them into glass liquid. The quality of the glass liquid is crucial for the quality of the final glass products. Therefore, it is necessary to monitor the raw material melting process in the glass furnace in real time. Thus, an observation port is usually provided on the glass furnace to observe the internal situation of the glass furnace.

[0003] The furnace observation port is connected to the outside, which is not conducive to maintaining the temperature inside the furnace. The furnace observation devices in the prior art usually use a plug brick to block the observation port and pull it out when observation is needed. However, the plug brick is affected by the high-temperature environment inside the furnace for a long time, and its temperature is relatively high. Moreover, due to its own heavy weight, it is easy for the staff to get injured when pulling it out. At the same time, the volatile substances will cause the plug brick to adhere to the frame of the observation port, making it difficult to pull out the plug brick. Therefore, a furnace observation device that is convenient for the staff to use and will not be adhered by volatile substances is needed.

[0004] Chinese Utility Model Patent CN 205528370 U discloses a furnace, in which an observation device provided with a slide rail and a slide plate is used. When not observing, the slide plate just covers the observation port. When observation is needed, the slide plate is moved along the slide rail to a position where it does not block the observation port, and then the internal situation of the furnace can be observed. This technical solution facilitates the operation of the operator to open and close the observation device and avoids the problem that volatile substances adhere to the periphery of the slide plate, resulting in difficult sliding. However, in the actual use process, one side of the slide plate is exposed to the high-temperature environment inside the furnace for a long time and is prone to heat deformation, which makes it difficult to completely close the observation port, and then the heat inside the furnace leaks out. When the furnace works for a long time, the slide plate is heated for a long time, and its temperature will also rise, making it difficult for the relevant staff to directly slide it back and forth. Therefore, a furnace observation device that is convenient for the staff to operate and reduces heat deformation is needed. Utility Model Content

[0005] The technical problem to be solved by the present disclosure is: how to ensure the simple operation of the furnace observation device while avoiding the deformation of the observation device caused by heat.

[0006] To solve the above technical problems, in a first aspect, embodiments of the present disclosure provide a kiln observation device, which is disposed on an observation port opened on a kiln wall and includes a slide rail part and a slider part. The slide rail part includes an anchoring bracket and a pulley group. The pulley group includes a plurality of pulleys that are oppositely arranged on the upper and lower parts of the anchoring bracket and are respectively arranged in a horizontal direction. The slider part includes a clamping bracket and a refractory brick detachably installed in the clamping bracket. The clamping bracket is slidably disposed in the anchoring bracket and is respectively in contact with the pulley group at the upper and lower ends, so as to be adjustable along the arrangement direction of the pulleys to block or stagger the observation port with the refractory brick.

[0007] In some embodiments, the slide rail part further includes a limit pin disposed on the anchoring bracket. The limit pins are respectively disposed at both ends of the pulley group to define the limit adjustment positions of the clamping bracket.

[0008] In some embodiments, the distance between two limit pins disposed at the same end of the clamping bracket is greater than the width of the slider part.

[0009] In some embodiments, the slide rail part further includes a fastening bolt and a rotating setscrew fixed on the anchoring bracket. A setscrew jack for threaded connection of the rotating setscrew is provided on the fastening bolt. When the slider part completely blocks the observation port, the rotating setscrew can pass through the setscrew jack and abut against the slider part.

[0010] In some embodiments, the area of the refractory brick is larger than the observation port, and it can completely cover the observation port when it slides to the observation port.

[0011] In some embodiments, the slider part further includes sealing patches respectively disposed on the upper and lower end faces of the refractory brick.

[0012] In some embodiments, the sealing patches are made of an elastic material, one end of which abuts against the pulley group and the other end abuts against the refractory brick.

[0013] In some embodiments, the slider part further includes a push-pull handle disposed on the clamping bracket for controlling the slider part.

[0014] In some embodiments, the slider part further includes a heat dissipation member disposed on the refractory brick.

[0015] In a second aspect, embodiments of the present disclosure further provide a kiln, on which an observation port is opened, and the above-mentioned kiln observation device is disposed on the observation port.

[0016] In the technical solution of the present disclosure, when observation is not required, the refractory bricks on the slider part can completely block the observation opening provided on the kiln furnace, thereby ensuring that no heat leakage occurs at the observation opening and ensuring the stability of the temperature inside the kiln furnace; when observation is required, the slider part can slide to a position where it does not block the observation opening through the pulleys arranged at intervals in contact with it, so as to be able to observe the internal operation of the kiln furnace and conduct real-time monitoring. By using refractory bricks that can withstand high-temperature environments for a long time without deformation, it can be ensured that the slider part can always completely block the observation opening during the operation of the kiln furnace, preventing heat leakage, and thus ensuring the normal operation of the kiln furnace. Through the refractory bricks with low heat transfer efficiency and low surface temperature and the slide rail part provided with a pulley group, it enables the staff to conveniently move the slider part and conduct observation when observation is required, and conveniently slide the slider part to a position where it completely blocks the observation opening after the observation is completed. The entire operation process is simple, and the refractory bricks will not be deformed by heat, resulting in the slider part being stuck and unable to slide. BRIEF DESCRIPTION OF THE DRAWINGS

It should also be understood that terms defined in a general dictionary, such as, should be construed as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0028] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0029] To solve the above technical problems, in a first aspect, embodiments of the present disclosure provide a kiln observation device, as Figure 1 shown. The kiln observation device is disposed on an observation port opened on the kiln wall, and includes a slide rail portion and a slider portion. The slide rail portion includes an anchoring bracket 8 and a pulley group 9. The pulley group 9 includes a plurality of pulleys that are oppositely arranged on the upper and lower portions of the anchoring bracket 8 and are respectively arranged in a horizontal direction. The slider portion includes a clamping bracket 10 and a refractory brick 1 detachably installed in the clamping bracket 10. The clamping bracket 10 is slidably disposed in the anchoring bracket 8 and contacts the pulley group 9 at the upper and lower ends respectively, so as to be adjusted along the arrangement direction of the pulleys to block or stagger the observation port with the refractory brick 1.

[0030] When observation is not required, the refractory brick on the slider portion can completely block the observation port opened on the kiln, thereby ensuring that the hot air in the furnace does not leak from the observation port and ensuring the stability of the temperature in the kiln. When observation is required, the slider portion can slide to a position that does not block the observation port through the spaced-apart pulleys in contact therewith, so as to be able to observe the internal operation of the kiln and perform real-time monitoring. By using refractory bricks that can withstand high-temperature environments for a long time without deformation, it can be ensured that the slider portion can always completely block the observation port during the operation of the kiln, preventing heat leakage, and thus ensuring the normal operation of the kiln. Through the refractory bricks with low heat transfer efficiency and low surface temperature and the slide rail portion provided with a pulley group, it enables the staff to conveniently move the slider portion and observe when observation is required, and conveniently slide the slider portion to a position that completely blocks the observation port after the observation is completed. The entire operation process is simple, and the refractory bricks will not be stuck due to heat deformation, resulting in the slider portion being unable to slide.

[0031] Through the clamping bracket 10 and the refractory brick 1 detachably installed thereon, the refractory brick 1 can be quickly replaced when it is deformed or damaged after long-term operation, thereby simplifying the replacement steps of the observation device and facilitating the staff to replace the refractory brick 1 in a timely manner.

[0032] In some embodiments, the refractory brick 1 with a corrosion-resistant coating on the surface can be selected. When the refractory brick 1 is blocked to the observation port and contacts the internal environment of the kiln, the volatile substances in the kiln contact and adhere to the surface of the refractory brick 1. Using the refractory brick 1 with a corrosion-resistant coating can prevent the corrosive volatile substances from corroding and damaging the refractory brick 1, so as to ensure that the refractory brick 1 can work stably for a long time under the condition of contact with corrosive volatile substances.

[0033] In some embodiments, as Figure 1 and Figure 2As shown, the slide rail part also includes a limit pin 3 arranged on the anchor bracket 8, and the limit pin 3 is respectively arranged at both ends of the pulley block 9 to limit the limit adjustment position of the clamping bracket 10. The lower end of the limit pin 3 installed on the anchor bracket 8 extends from the anchor bracket 8 into the interior of the pulley block 9 installed thereon, and the length of the limit pin 3 extending therein is greater than the diameter of the pulley in the pulley block 9, so that when the slider slides to the edge of the pulley block 9, it can contact the slider part abutting against the pulley block 9. When the slider part slides to the limit position on the slide rail part along the direction of the pulley arrangement in the pulley block 9, the upper and lower ends of the slider part are simultaneously blocked by the limit pin 3 arranged in the pulley arrangement direction, thereby preventing the slider part from continuing to slide along the pulley arrangement direction and partially leaving the range of the slide rail part or even sliding out of the slide rail part.

[0034] In some embodiments, the spacing distance between the two stop pins 3 provided at the same end of the clamping bracket 10 is greater than the width of the slider. When the slider is slid, the stop pins 3 having a spacing distance greater than that of the slider can slide away from the observation port, thereby exposing the observation port for observing the working conditions in the furnace, and after the observation is completed, the slider can slide above the observation port and completely block the observation port to prevent the hot air in the kiln from leaking out.

[0035] In some embodiments, a motor connected to the pulleys in each pulley block 9 can be provided, and the pulleys can be driven to rotate forward or reverse by adjusting the motor to rotate forward or reverse, thereby driving the slider portion abutting against the pulley to move toward or away from the observation port on the slide rail portion. By using a motor, the staff can move the slider portion closer to or away from the observation port without contacting the slider portion, simplifying the operation steps of the kiln observation device while eliminating the safety hazard of manual operation of the slider portion that contacts the high temperature environment in the kiln and the refractory bricks 1 heated by the high temperature environment in the kiln by the slider portion that does not require manual operation.

[0036] In some embodiments, Figure 1 and Figure 2 As shown, the slide rail portion also includes a fastening bolt 4 and a rotating top screw 5 fixed on the anchor bracket 8. The fastening bolt 4 is provided with a top screw insertion hole 11 for the rotating top screw 5 to be threadedly connected. When the slide block portion completely blocks the observation port, the rotating top screw 5 can pass through the top screw insertion hole 11 and abut against the slide block portion. Figure 1As shown, two fastening bolts 4, a rotating set screw 5 and a set screw socket 11 are arranged opposite to each other at the upper and lower ends of the anchoring bracket 8. When the slider part moves to the position where it completely blocks the observation port, the rotating set screw 5 passes through the set screw socket 11 and abuts against the slider part; when it is necessary to observe the inside of the kiln, first screw out the rotating set screw 5 from the set screw socket until the rotating set screw 5 no longer abuts against the slider part, and then move the slider part to a position where it does not affect the observation of the inside of the kiln. By means of the rotating set screw 5 abutting against the slider part, it is possible to prevent the slider part from sliding on the slide rail part due to external interference when it completely blocks the observation port, and it is also possible to apply a pressure to the slider part in the direction of the observation port and the inside of the kiln by abutting against the slider part, thereby preventing the hot air and air flow in the kiln from leaking through the gap between the slider part and the kiln wall. By selecting the threaded connection of the set screw socket 11 and the rotating set screw 5, it can be ensured that the rotating set screw 5 can stably abut against the slider part without being affected by external forces and falling off.

[0037] In some embodiments, the fastening bolt 4 is welded to the anchoring bracket 8. By welding the fastening bolt 4 and opening holes in it to set the set screw socket 11, the strength of the set screw socket 11 can be ensured without using high-strength materials to make the anchoring bracket 8, thereby saving costs and ensuring that the set screw socket 11 will not be damaged due to the force of the rotating set screw 5 during connection and causing the rotating set screw 5 to be unable to abut against the slider part.

[0038] In some embodiments, the area of the refractory brick 1 is larger than the observation port, and when it slides to the observation port, it can completely cover the observation port. When the slider part slides to the observation port, the high-temperature environment inside the kiln connected to the observation port only contacts the refractory brick 1, and other components of the slider part are not exposed to the high-temperature environment. Through the slider part where only the refractory brick 1 contacts the high-temperature environment in the kiln, it can be ensured that other components on the slider part are at normal temperatures and will not be deformed due to high temperatures.

[0039] In some embodiments, as Figure 1 and Figure 2 shown, the slider part further includes sealing patches 2 respectively arranged on the upper and lower end faces of the refractory brick 1. The sealing patches 2 fill the gap between the refractory brick 1 and the pulley group 9, so that the hot air in the furnace will not leak out through the gap between the refractory brick 1 and the pulley group 9, ensuring that the slider part can completely close the observation port when it is on the observation port, so that the technological process in the kiln can proceed normally.

[0040] In some embodiments, the sealing patch 2 is made of an elastic material. One end of the sealing patch abuts against the pulley block 9, and the other end abuts against the refractory brick 1. By using a sealing patch that is larger in size than the gap between the refractory brick 1 and the pulley block 9 and is elastic, the sealing patch 2 can be squeezed when it abuts against the pulley block 9 to completely fill the gap between the refractory brick 1 and the pulley block 9, thereby obtaining a better sealing effect and preventing the hot air in the kiln from leaking out.

[0041] When the refractory brick 1 needs to be replaced, first remove all the limit pins 3 on the side of the anchoring bracket 8 away from the observation port, and loosen the rotating set screw 5. Slide the slider part in the direction away from the observation port until the slider part falls out from this side and disengages from the slide rail part. At this time, remove the sealing patch 2, replace the new refractory brick 1, and then reinstall the sealing patch at the upper and lower ends of the new refractory brick 1. Install the refractory brick 1 and the sealing patch 2 back into the clamping bracket 10 to form the slider part, and reinstall the slider part back onto the slide rail part from the slide rail part on the side away from the observation port. When the slider part moves to the side close to the observation port and abuts against the limit pin 3 on this side, reinstall the limit pin 3 on the side of the anchoring bracket 8 away from the observation port onto the anchoring bracket 8. This operation process can be completed by a single person, and only replacing the refractory brick 1 can ensure the stable operation of the entire kiln observation device, thus saving the maintenance and operation costs of the equipment.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the slider part further includes a push-pull handle 6 provided on the clamping bracket 10 for controlling the slider part. By means of the push-pull handle 6 provided on the clamping bracket 10, the staff can use it to slide the slider part on the slide rail part, so that the slider part can block the observation port or move away from the observation port as needed. And because it is installed on the clamping bracket 10 that does not contact the high-temperature environment inside the furnace, its temperature is close to room temperature, and it can be touched and operated by the staff with bare hands or wearing heat-insulating gloves, thus simplifying the work process of observing the inside of the kiln, improving the efficiency of the observation work and reducing the risk of being scalded during the observation process.

[0043] In some embodiments, such as Figure 1 As shown, the slider part further includes a heat dissipation part 7 provided on the refractory brick 1. By means of the heat dissipation part 7 provided on the refractory brick 1, the refractory brick 1 can be dissipated heat when the slider part moves to the observation port, thereby preventing the refractory brick 1 from deforming due to excessive temperature, and further preventing problems such as the hot air in the kiln leaking out and the refractory brick 1 being damaged.

[0044] In some embodiments, such as Figure 1 and Figure 2As shown, the heat dissipation member 7 is a fin radiator made of a material with high thermal conductivity. When the kiln is operating at a high temperature, the heat dissipation member 7 can quickly conduct the heat of the refractory brick 1 to the fins thereon, and the fins transfer the heat to the air through heat convection, thereby quickly dissipating heat. By using the fin radiator, the refractory brick 1 can be quickly cooled, ensuring that the refractory brick 1 will not be deformed or damaged due to excessive temperature. At the same time, the heat dissipation member 7 of the fin radiator has a simple structure, low failure rate and is convenient for maintenance and replacement.

[0045] In some embodiments, the heat dissipation member 7 may further include an air guiding duct and a fan provided on the slider portion. When the kiln is operating at a high temperature and the slider portion blocks the observation port, the fan can generate a heat dissipation air flow, and blow the heat dissipation air flow to the heat dissipation member 7 through the air guiding duct with the air outlet pointing to the heat dissipation member 7, thereby dissipating heat from the heat dissipation member 7. By adding the fan and the air guiding duct, the temperature of the heat dissipation member 7 can be reduced, thereby further improving the heat dissipation efficiency of the heat dissipation member 7, and further reducing the temperature of the refractory brick 1 connected thereto and preventing it from deforming.

[0046] In a second aspect, an embodiment of the present disclosure further provides a kiln, which is provided with an observation port, and the above-mentioned kiln observation device is arranged on the observation port. Using the above-mentioned kiln observation device can prevent the high-temperature environment and volatile substances in the kiln from causing the kiln observation device to malfunction or be damaged. At the same time, the operator of the kiln can open or close the observation device through a safe and convenient operation and observe the working state in the kiln.

To avoid obscuring the concept of the present disclosure, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present disclosure.
