Description

Technical Field

[0001] This invention relates to the field of industrial kiln technology, and more particularly to an industrial kiln with an observable interior. Background Technology

[0002] Industrial kilns are an indispensable piece of equipment in industrial production, widely used in ceramics, metallurgy, chemicals, building materials and other industries. Their core function is to carry out processes such as firing, smelting and heat treatment of materials in a high-temperature environment, so as to cause physical and chemical changes in the materials to meet the requirements of different industries for product performance and quality.

[0003] However, due to the high temperature and enclosed state inside the kiln, it is difficult for staff to directly observe the actual firing status of the materials inside. They can only rely on experience or indirect parameters to judge the working status of the kiln, which greatly increases the uncertainty and risk of the production process. If abnormalities such as uneven temperature distribution, over-firing or under-firing of materials occur inside the kiln, and staff fail to detect and adjust them in time, it may lead to a decline in product quality or even a production accident, causing serious economic losses. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems: There is a lack of direct observation of the kiln's interior.

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, embodiments of the present invention propose an industrial kiln with an observable interior, comprising a base, an observation mechanism, and a cooling mechanism. A fixed frame is mounted on the base, and an outer furnace body is fixed inside the fixed frame. An inner furnace body is fitted against the inner wall of the outer furnace body. A placement plate is provided inside the inner furnace body to support materials. A closed furnace door is pivotally connected to the fixed frame, and an observation hole is provided on the closed furnace door. A control cabinet is arranged on the base and adjacent to the fixed frame. The observation mechanism includes an infrared camera, a baffle, and quartz glass. The infrared camera and the quartz glass are arranged within the observation hole. An infrared camera is connected to the control cabinet. The quartz glass is located between the infrared camera and the inner furnace body. The baffle is pivotally connected to the closed furnace door via a rotating shaft. The baffle can close the observation hole. The cooling mechanism includes a heat dissipation cavity, a water tank, a water pump, an outlet pipe, and an inlet pipe. The heat dissipation cavity is arranged on the outer furnace body. The water tank is arranged on the base. Both ends of the inlet pipe are connected to the heat dissipation cavity and the water tank. Both ends of the outlet pipe are connected to the heat dissipation cavity and the water tank. The water pump is arranged on the inlet pipe.

[0007] The present invention has the advantages and technical effects of allowing observation of the interior without affecting the heat inside the kiln.

[0008] In some embodiments, multiple pieces of quartz glass are arranged inside the observation hole, and inert gas is filled between the quartz glass pieces and adjacent quartz glass pieces.

[0009] In some embodiments, a fan is provided on the outer wall of the water storage tank to dissipate heat from the cooling water inside the water storage tank.

[0010] In some embodiments, a water inlet is provided on the top of the water storage tank, and a sealing cap is provided at the water inlet to close the water inlet.

[0011] In some embodiments, a movable column is provided on the baffle, the movable column being perpendicular to the surface of the baffle and extending away from the baffle.

[0012] In some embodiments, a retaining post is also included, which is disposed on the closed furnace door and can abut against the baffle.

[0013] In some embodiments, an audible and visual alarm is installed on the control cabinet.

[0014] In some embodiments, heat-resistant insulation cotton is filled between the inner wall of the fixing frame and the outer furnace body, and a sealing groove is provided on the fixing frame corresponding to the position of the closed furnace door, the sealing groove being able to fit with the closed furnace door.

[0015] In some embodiments, a plurality of ventilation holes are evenly distributed on the placement plate.

[0016] In some embodiments, a liquid level sensor is installed inside the water storage tank, and the liquid level sensor is connected to the control cabinet.

[0017] This solution offers the following advantages: More comprehensive and precise observation capabilities. Relying on experience or indirect parameters to judge operating conditions can easily lead to quality problems or accidents. The observation port, utilizing an infrared camera, baffle, and quartz glass, provides dual protection through both direct visual observation and precise data monitoring, significantly improving the comprehensiveness and accuracy of observation. A closed-loop circulation system is formed through the water tank, pump, inlet pipe, and outlet pipe. Cooling water absorbs heat from the furnace body in the heat dissipation cavity and then flows back, where it is cooled by the fan radiator and can be reused, resulting in higher cooling efficiency and water conservation.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] An embodiment of the present invention provides an industrial kiln 1 with an observable interior, comprising a base 11, an observation mechanism 2, and a cooling mechanism 3. A fixing frame 12 is provided on the base 11, and an outer furnace body 13 is fixed inside the fixing frame 12. An inner furnace body 14 is fitted against the inner wall of the outer furnace body 13, and a placement plate 15 is provided inside the inner furnace body 14 to carry materials. A closed furnace door 16 is pivotally connected to the fixing frame 12, and an observation hole 21 is provided on the closed furnace door 16. A control cabinet 17 is arranged on the base 11 and adjacent to the fixing frame 12. The observation mechanism 2 includes an infrared camera 23, a baffle 25, and a quartz glass 22. The infrared camera 23 and the quartz glass 22 are arranged in the observation hole. Inside 21, infrared camera 23 is connected to control cabinet 17. Quartz glass 22 is located between infrared camera 23 and inner furnace body 14. Baffle 25 is pivotally connected to closed furnace door 16 via rotating shaft 24. Baffle 25 can close observation hole 21. Cooling mechanism 3 includes heat dissipation cavity 31, water tank 32, water pump 33, water outlet pipe 35 and water inlet pipe 34. Heat dissipation cavity 31 is arranged on outer furnace body 13. Water tank 32 is arranged on base 11. Both ends of water inlet pipe 34 are connected to heat dissipation cavity 31 and water tank 32. Both ends of water outlet pipe 35 are connected to heat dissipation cavity 31 and water tank 32. Water pump 33 is arranged on water inlet pipe 34.

[0025] The base 11 serves as the supporting foundation for the entire industrial kiln 1, bearing the fixed frame 12 and preventing displacement due to vibration during kiln operation, thus ensuring the stability of the overall structure. The fixed frame 12, installed on the base 11, provides fixation and protection for the outer furnace body 13, enhancing overall rigidity. The outer furnace body 13 is fixed inside the fixed frame 12, forming a double-layer structure with the inner furnace body 14, which is attached to its inner wall. The outer furnace body 13 isolates the furnace from external environmental interference, while the inner furnace body 14 directly contacts the material, providing a stable high-temperature space for material heating. The placement plate 15 inside the inner furnace body 14 can support the material to be processed, ensuring uniform material distribution, consistent heating, and improved product quality. The sealed furnace door 16, connected to the fixed frame 12 via a pivoting mechanism, facilitates material loading and unloading. When closed, it tightly seals the internal space of the furnace, reducing heat loss and the entry of external impurities. The observation hole 21 provides a channel for observing the interior of the kiln. The control cabinet 17 is positioned adjacent to the fixed frame 12 on the base 11, facilitating wiring connections with various electrical components and allowing staff to operate it conveniently. It receives and processes signals transmitted from the infrared camera 23 in real time, providing a clear view of the kiln's operating data. The quartz glass 22, located between the infrared camera 23 and the inner furnace body 14, utilizes its high-temperature resistance and light transmittance to prevent damage from high temperatures and impurities inside the furnace to the infrared camera 23, while ensuring smooth infrared light penetration for clear imaging. The infrared camera 23 is connected to the control cabinet 17, capturing real-time temperature distribution and material reactions within the kiln, and accurately transmitting the data to the control cabinet 17. This provides staff with a basis for judging the furnace's condition and adjusting operating parameters. The baffle 25 is pivotally connected to the closed furnace door 16 via a rotating shaft 24, allowing the observation hole 21 to be closed when observation is not required, preventing heat loss and impurity intrusion, and maintaining a stable furnace temperature. In the cooling mechanism 3, the heat dissipation cavity 31 is arranged on the outer furnace body 13, which can directly absorb the heat generated by the furnace body. The water storage tank 32 is set on the base 11, which is convenient for connection with the pipeline and provides a stable storage space for cooling water. The water inlet pipe 34 and the water outlet pipe 35 together form a cooling water circulation path. The water pump 33 is installed on the water inlet pipe 34 to provide power for the flow of cooling water, and to drive the cooling water to circulate continuously between the water storage tank 32 and the heat dissipation cavity 31, which efficiently removes the heat of the furnace body, avoids damage to the furnace body due to excessive temperature, and prevents the material from being affected by overheating, thus ensuring that the kiln can operate stably for a long time.

[0026] The advantages and technical effects brought about by the independent claims according to the embodiments of the present invention.

[0027] In some embodiments, multiple pieces of quartz glass 22 are arranged inside the observation hole 21, and inert gas is filled between the quartz glass 22 and the adjacent quartz glass 22.

[0028] Specifically, 2-4 pieces of quartz glass 22 are arranged inside the observation hole 21 (adapted to the furnace operating temperature; 2 pieces are used for medium and low temperature conditions, and 3-4 pieces are used for high temperature conditions above 1200℃). High-purity inert gas, preferably nitrogen or argon, is filled between adjacent pieces of quartz glass 22. Multiple pieces of quartz glass 22 form a multi-layered thermal barrier. Combined with the low thermal conductivity of the inert gas, this effectively blocks the conduction of high temperatures from the furnace interior to the exterior. Compared to a single piece of quartz glass 22, heat loss is reduced, energy waste is decreased, and the furnace temperature is maintained uniformly, preventing localized deviations in process parameters due to heat dissipation from the observation hole 21. The inert gas is chemically stable, non-flammable, and non-oxidizing, preventing oxidation and corrosion of the quartz glass 22 upon contact with air at high temperatures. It also prevents the formation of water vapor or impurity deposits between the glass pieces, extending the service life of the quartz glass 22. The multi-piece structure can also disperse thermal stress, and with the buffering effect of inert gas, it can improve the thermal shock resistance of quartz glass 22, effectively avoid the risk of single glass shattering due to excessive temperature difference, and ensure the long-term stable operation of observation mechanism 2.

[0029] In some embodiments, a fan 36 is provided on the outer wall of the water storage tank 32, and the fan 36 dissipates heat from the cooling water inside the water storage tank 32.

[0030] Specifically, when fan 36 operates, it accelerates airflow over the surface of water tank 32, quickly removing heat conducted through the tank walls. Compared to natural heat dissipation, this method improves heat dissipation efficiency by 3-5 times. It also rapidly cools the cooling water that has heated up after absorbing heat from the furnace, ensuring that the cooling water returning to the heat dissipation cavity 31 remains at a suitable temperature. This guarantees continuous and efficient cooling circulation and prevents the furnace cooling effect from diminishing due to excessively high cooling water temperature. Fan 36 has a simple cooling structure, low energy consumption, small footprint, and low operating noise, minimizing disruption to the surrounding working environment. Continuously cooling the water prevents accelerated equipment aging caused by continuously rising water temperature in water tank 32. Simultaneously, the stable cooling effect reduces furnace temperature fluctuations, providing a stable temperature environment for material processing and ensuring product quality.

[0031] In some embodiments, a water inlet 37 is provided on the top of the water tank 32, and a sealing cap 38 is provided at the water inlet 37 to close the water inlet 37.

[0032] Specifically, the water inlet 37 is located at the top, allowing staff to easily replenish cooling water without moving the water tank 32 or disassembling the pipeline. The operation is direct, labor-saving, and improves the speed of water replenishment. The sealing cap 38 tightly seals the water inlet 37, effectively preventing external impurities such as industrial dust, dirt, and debris from entering the water tank 32, avoiding contamination of the cooling water. This prevents blockage or wear of cooling system components such as the heat dissipation cavity 31, inlet pipe 34, and water pump 33 due to impurity accumulation, ensuring smooth circulation cooling. At the same time, the sealing cap 38 reduces evaporation loss of cooling water under high-temperature environments, maintains a stable water volume in the water tank 32, reduces the frequency of water replenishment, and saves manpower and water resources. The seal ensures the airtightness of the cooling system, preventing unstable air pressure in the water tank 32 due to air leakage at the water inlet 37, ensuring balanced water pumping pressure, stable cooling water circulation power, and avoiding fluctuations in cooling effect.

[0033] In some embodiments, a movable post 26 is provided on the baffle 25, the movable post 26 being perpendicular to the surface of the baffle 25 and extending away from the baffle 25.

[0034] Specifically, the movable column 26 provides a clear and convenient point of force application for the operator, allowing the baffle 25 to rotate around the rotation axis 24 without directly holding the baffle 25 body. Compared to directly operating the baffle 25, the force application is more concentrated and less strenuous, making it suitable for industrial kilns where the baffle 25 is heavy due to its high-temperature resistant design, and facilitating the opening and closing of the observation hole 21. The vertical extension ensures that the direction of force application and the rotation trajectory of the baffle 25 form the optimal force angle, avoiding jamming caused by force deviation, ensuring smooth rotation of the baffle 25, and allowing precise control of the opening angle (such as fully open or partially open) to meet different observation needs. The movable column 26 extends away from the baffle 25, keeping the operator's hands away from the high-temperature sealed furnace door 16 and the surface of the baffle 25, preventing burns from contact with high-temperature components and improving operational safety.

[0035] In some embodiments, a handle 4 is provided on the outer wall of the sealed furnace door. Understandably, the handle 4 greatly facilitates the operation of the sealed furnace door by the operator. When it is necessary to open the sealed furnace door for material feeding or retrieval, the operator only needs to grasp the handle 4 and apply appropriate force to easily open the sealed furnace door, avoiding potential safety hazards such as burns from direct contact with the high-temperature furnace door, thus improving the safety and convenience of operation. Similarly, when closing the sealed furnace door, operation via the handle 4 allows for more precise control of the closing force and angle, ensuring a tight fit between the sealed furnace door and the fixed frame 12, effectively preventing heat loss and the entry of external impurities into the kiln. An anti-slip sleeve 5 is provided on the outer wall of the handle 4.

[0036] Understandably, the anti-slip sleeve 5 further enhances the ease of operation and safety of the handle 4. Since the closed furnace door is large and heavy, a certain amount of force needs to be applied during operation. The anti-slip sleeve 5 can increase the friction between the hand and the handle 4 to prevent operational errors or dangers caused by slipping.

[0037] In some embodiments, a retaining post 27 is also included, which is arranged on the closed furnace door 16 and can abut against the baffle 25.

[0038] Specifically, the locking post 27 can form a stable contact with the baffle 25 when it is opened to a suitable observation angle, temporarily fixing the baffle 25. This eliminates the need for operators to continuously hold the moving post 26 to maintain the position of the baffle 25, freeing their hands. This is especially suitable for situations requiring long-term observation of the kiln interior or simultaneous data recording, significantly reducing operator fatigue. The baffle 25 remains precisely and stably positioned after contact, preventing displacement or falling due to vibration, minor collisions, or other external forces. This ensures the observation hole 21 remains stably open, preventing the baffle 25 from shaking and affecting the clarity of visual observation or the imaging stability of the infrared camera 23. The locking post 27's limiting function prevents excessive rotation of the baffle 25, which could cause collisions and friction with the edge of the observation hole 21, the quartz glass 22, or other components, reducing wear on the baffle 25 and extending the overall service life of the observation mechanism 2. The locking post 27 provides a clear positioning reference for the baffle 25, allowing operators to quickly and easily fix the baffle 25 at commonly used observation angles without repeated adjustments, making it quite convenient.

[0039] In some embodiments, an audible and visual alarm is installed on the control cabinet 17.

[0040] Specifically, the audible and visual alarm, through the dual function of sound warning and light indication, can quickly attract the attention of staff when abnormalities occur in the kiln (such as overheating, cooling system failure, low cooling water level, or baffle 25 not being fully closed). Compared to simple text or light prompts, the warning effect is stronger and more conspicuous, effectively preventing the omission of faults due to noisy environments or staff distraction, thus gaining time for timely handling. Its placement on control cabinet 17 forms a linkage with the kiln control core, receiving fault signals transmitted from control cabinet 17. It has a fast response speed, and its centralized location allows staff to quickly locate the source of the fault, eliminating the need to search for abnormalities throughout the equipment, thus improving fault handling efficiency. The audible and visual alarm is not limited by distance; even if staff are moving within a certain range around the kiln, they can still detect the alarm signal in time, avoiding delays in handling due to distance from the equipment, further reducing the risk of production accidents.

[0041] In some embodiments, heat-resistant insulation cotton is filled between the inner wall of the fixing frame 12 and the outer furnace body 13, and a sealing groove is provided on the fixing frame 12 at the position corresponding to the closed furnace door 16, and the sealing groove can fit with the closed furnace door 16.

[0042] Specifically, the heat-resistant insulation cotton, with its low thermal conductivity, effectively blocks the heat transfer from the outer furnace body 13 to the fixed frame 12, reducing overall heat loss from the furnace. Compared to an uninsulated structure, the thermal efficiency can be increased by 25%-35%, reducing energy consumption and maintaining a uniform and stable temperature field inside the furnace, preventing fluctuations in material processing quality due to uneven local heat dissipation. The insulation cotton also possesses good elasticity and thermal stability, buffering the thermal expansion and contraction stress of the outer furnace body 13 under high-temperature conditions. This prevents damage caused by the deformation and mutual compression between the fixed frame 12 and the outer furnace body 13, extending the service life of the furnace structure. Furthermore, the insulation cotton reduces the temperature of the outer wall of the fixed frame 12, preventing burns to workers upon contact and improving operational safety. The sealing groove on the fixed frame 12 fits into the closed furnace door 16 to form a tight sealing structure, which can seal the gap between the furnace door and the fixed frame 12, prevent heat from leaking out of the gap, consolidate the heat preservation effect, and prevent outside air, dust and other impurities from entering the furnace, avoid material oxidation pollution or impurities affecting the processing technology, and also reduce the noise generated by the leakage of high temperature airflow in the furnace, thus improving the working environment.

[0043] In some embodiments, a plurality of ventilation holes are evenly distributed on the placement plate 15.

[0044] Specifically, the evenly distributed ventilation holes break down the obstruction of hot airflow within the furnace by the placement plate 15, allowing high-temperature hot air to smoothly penetrate the placement plate 15 and achieve hot airflow circulation between the upper and lower surfaces of the material. This avoids the problems of heat accumulation at the bottom of the material and uneven heating caused by the solid placement plate 15, improving the consistency of material processing quality, and is especially suitable for products with stringent requirements for temperature uniformity. Simultaneously, the smooth flow of hot air accelerates the equalization of the temperature field within the furnace, reduces the time required for kiln heating, improves heat utilization efficiency, and reduces energy consumption. The ventilation holes also reduce the weight of the placement plate 15 itself, making it easier for workers to handle materials, and allow volatiles or waste gases generated during material processing to be quickly discharged through the ventilation holes, preventing their accumulation on the material surface and affecting product quality. Furthermore, the ventilation holes reduce thermal stress concentration on the placement plate 15 under high-temperature environments, reducing the risk of deformation due to thermal expansion and contraction, and extending the service life of the placement plate 15.

[0045] In some embodiments, a liquid level sensor is installed inside the water storage tank 32, and the liquid level sensor is connected to the control cabinet 17.

[0046] Specifically, the liquid level sensor accurately monitors the changes in the cooling water level in the water storage tank 32 in real time, and transmits the water level data synchronously to the control cabinet 17. Staff can intuitively monitor the water level status through the display screen on the control cabinet 17, eliminating the need for manual opening of the tank for inspection, avoiding safety hazards during operation in high-temperature environments, and reducing maintenance workload. When the water level falls below the set minimum threshold, the sensor triggers a signal, which, through the control cabinet 17, activates an audible and visual alarm to issue a low-level warning, reminding staff to replenish water promptly. This prevents damage to the water pump 33 due to water shortage, or overheating of the furnace body caused by interruption of the cooling system circulation, thus avoiding equipment failure and production accidents at the source. When the water level reaches the set maximum threshold, water replenishment stops, preventing cooling water overflow and waste, and maintaining a humid environment, achieving precise water volume control.
