Description

Technical Field

[0001] This utility model belongs to the field of kiln production technology, and specifically relates to a visual device and a kiln. Background Technology

[0002] During the production process, observing the dynamic movement of ceramic tiles inside the kiln is a crucial operational requirement. Currently, production relies solely on close-range visual observation by humans. However, in high-temperature environments, personnel have limited tolerance and cannot conduct continuous observation for extended periods, thus affecting the adjustment level of the kiln's melting process. Utility Model Content

[0003] The purpose of this invention is to provide a visual device and a kiln to solve the technical problem of difficulty in continuously monitoring brick movement in the kiln in the prior art.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This utility model discloses a visual device applied to a kiln, comprising:

[0006] A camera assembly, comprising a connected camera and a lens, the lens being installed inside the kiln;

[0007] A heat insulation component, wherein the heat insulation component is hollow and has a heat insulation cavity, the heat insulation cavity is connected to the interior of the kiln, and the camera component is inserted through the heat insulation cavity;

[0008] A cooling assembly is connected to the end of the heat insulation cavity located outside the kiln, so that the conveyed cooling gas is input into the kiln along the heat insulation cavity.

[0009] The present invention has at least the following beneficial effects: the lens is installed inside the kiln and is used to photograph the movement of the tiles inside the kiln and send the image to a camera outside the kiln. The camera converts the optical image into an analog electrical signal and sends it to a display screen or other display components, so that people can view the optical image on the display components and judge whether the movement of the tiles inside the kiln is reasonable. If it is not reasonable, the transmission structure of the kiln can be adjusted in time to correct the movement of the tiles.

[0010] The heat insulation component is hollow and has a heat insulation cavity. The camera component is installed inside the heat insulation cavity, so that the camera component is separated from the hot air of the kiln and avoids damage to the camera component by the high temperature of the kiln.

[0011] The cooling assembly is connected to the outside of the kiln. When the cooling assembly delivers cooling gas, the gas flows from the outside to the inside along the insulation cavity, cooling the camera assembly inside and preventing high-temperature damage from the kiln's hot air. The insulation cavity is connected to the inside of the kiln, allowing the cooling gas to be sprayed along the cavity towards the kiln. This suppresses the kiln flames while creating an air curtain between the lens and the hot kiln air, preventing the kiln flames from directly hitting the lens, extending the lifespan of the camera assembly, and enabling the visual device to continuously monitor the movement of the tiles.

[0012] As a further improvement to the above technical solution, a control component and a refrigeration component are provided at the connection between the cooling component and the heat insulation cavity, arranged along the direction of cooling gas delivery. The control component is provided with a detection component for detecting the temperature and pressure of the cooling gas. The control component is electrically connected to the camera component and the refrigeration component respectively.

[0013] As a further improvement to the above technical solution, a filter is provided between the cooling component and the control component.

[0014] As a further improvement to the above technical solution, the camera assembly also includes a camera rod, the camera rod being hollow and forming a first cavity, the lens being located in the first cavity, and the first cavity being connected to the cooling assembly.

[0015] As a further improvement to the above technical solution, the heat insulation component includes a heat insulation sleeve for accommodating the camera, the heat insulation sleeve being hollow and forming a second cavity, the second cavity being connected to the cooling component.

[0016] As a further improvement to the above technical solution, the heat insulation component also includes a heat insulation tube for accommodating the camera rod. The heat insulation tube is hollow and forms a third cavity. The third cavity is connected to the interior of the kiln and is connected to the cooling component.

[0017] As a further improvement to the above technical solution, the cooling component is connected to the first cavity, the third cavity and the filter respectively.

[0018] As a further improvement to the above technical solution, the visual device also includes a first connector and a second connector. The first connector is connected to the cooling component, the third cavity and the second connector respectively, and the second connector is also connected to the first cavity and the filter.

[0019] As a further improvement to the above technical solution, the control component is electrically connected to an alarm component.

[0020] This utility model discloses a kiln, including a roller and a viewing device as described in any of the above claims, wherein the lens is located above the roller.

[0021] The present invention has at least the following beneficial effects: through the optical images transmitted by the visual device, workers can remotely and continuously monitor the brick movement inside the kiln, which facilitates timely adjustment of the transmission structure inside the kiln and correction of the brick movement.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 3 The following are several embodiments of a visual device and a kiln of the present invention.

[0042] like Figures 1 to 3 As shown, the visual device 100 of this utility model embodiment is applied to a kiln 900. The visual device 100 includes a camera component 200, a heat insulation component 300, and a cooling component 400.

[0043] It is understood that the camera assembly 200 includes a camera 210 and a lens 220. Specifically, the lens 220 is installed inside the kiln 900 and is used to optically image the conveying of the ceramic tiles 920 inside the kiln 900 and generate an optical image. The lens 220 is connected to the camera 210, and the lens 220 sends the optical image to the camera 210. The camera 210 converts the optical image into an analog electrical signal, which is then transmitted to the display assembly.

[0044] Understandably, the heat insulation component 300 is hollow and forms a heat insulation cavity that can accommodate the camera component 200. One end of the heat insulation component 300 passes through and connects to the kiln 900, so that the heat insulation cavity and the interior of the kiln 900 are interconnected. The camera component 200 is arranged inside the heat insulation cavity, and the lens 220 is located at the end of the heat insulation cavity that passes through the interior of the kiln 900.

[0045] In this embodiment, the lens 220 is installed at one end of the heat insulation cavity located inside the kiln 900, and the camera 210 is located at the other end of the heat insulation cavity located outside the kiln 900, so that the camera assembly 200 is separated from the kiln 900 by the heat insulation cavity, reducing the possibility of the camera 210 being damaged by the high temperature of the kiln 900.

[0046] Understandably, the cooling component 400 is used to transport cooling gas, which serves to cool and protect the camera component 200, i.e., cooling the camera component 200 using air cooling. The output end of the cooling component 400 is connected to the insulation cavity located outside the kiln, allowing the transported cooling gas to flow from the insulation cavity outside the kiln 900 to the insulation cavity inside the kiln 900, thereby sequentially insulating and cooling the camera 210 and the lens 220. Since the insulation cavity is connected to the inside of the kiln 900, the cooling gas is transported from the end of the insulation cavity to the inside of the kiln 900.

[0047] With this setup, the visual device 100 can be installed in the transition zone before the quenching section of the kiln 900. When the visual device 100 is activated, the cooling component 400 delivers cooling gas into the insulation chamber to cool the camera component 200, enabling the camera component 200 to monitor the interior of the kiln 900 for an extended period of time under high temperature conditions. This allows workers to view the direction of the tiles 920 inside the kiln 900 through the display component and determine whether the direction of the tiles 920 is reasonable. If it is not reasonable, workers can adjust the transmission mechanism of the kiln 900 to correct the tile movement.

[0048] Moreover, since the heat insulation chamber is connected to the interior of the kiln 900, the cooling gas delivered at the end of the heat insulation chamber can be sprayed into the interior of the kiln 900, ensuring that the flames do not directly hit the lens 220, extending the service life of the camera assembly 200. In addition, the sprayed cooling gas can also suppress the flames inside the kiln.

[0049] Understandably, the visual device 100 can also be used for monitoring various kilns 900 in industries such as metallurgy, petrochemicals, cement, and power.

[0050] In some embodiments, the visual device 100 and the kiln 900 are started simultaneously to prevent the camera component 200 from being damaged by the high temperature inside the kiln.

[0051] In other embodiments, the visual device 100 is used in conjunction with a temperature control component inside the kiln 900. When the temperature is below a preset temperature, the visual device 100 does not activate, saving power and gas consumption. When the temperature exceeds the preset temperature, the visual device 100 automatically activates to prevent high temperatures inside the kiln from damaging the camera component 200.

[0052] It is understandable that the visual device 100 also includes a control component 500 and a cooling component 600, such as Figure 2 and Figure 3 As shown. Specifically, the control component 500 and the cooling component 600 are arranged in the connecting pipe between the cooling component 400 and the heat insulation cavity along the direction of cooling gas delivery. That is, the cooling gas delivered by the cooling component 400 first passes through the control component 500, and the cooling gas output from the control component 500 passes through the cooling component 600 before being delivered into the heat insulation cavity. The cooling component 600 is used to reduce the temperature of the cooling gas, so that the cooling gas can better protect the camera component 200 within the heat insulation cavity.

[0053] Understandably, the control component 500 includes a detection component that can detect the temperature of the cooling gas, allowing the control component 500 to adjust the cooling range of the cooling component 600, thereby controlling the temperature of the cooling gas input into the insulation cavity. The detection component can also detect the pressure of the cooling gas to prevent excessively low pressure from affecting its heat dissipation effect on the camera component 200.

[0054] Understandably, the outer surface of the control component 500 is also equipped with a control panel 530, such as... Figure 2 As shown, the control panel 530 is electrically connected to the detection component, enabling it to display the temperature and / or pressure of the cooling gas.

[0055] Understandably, the control component 500 can adjust the pressure of the cooling gas in conjunction with pressurizing equipment such as pressurizing pumps and valves based on the pressure detected by the detection component.

[0056] It is understood that the control component 500 is electrically connected to the camera component 200. Specifically, the control component 500 is connected to the camera 210 via cable 510, such as... Figure 2As shown, cable 510 is used to power camera 210 and to transmit the analog electrical signals from camera 210 to control component 500. Control component 500 then transmits the signals to display component via wired or wireless network. Display component can be a display screen, computer monitor, etc., to facilitate workers to monitor the brick movement in kiln 900.

[0057] In this embodiment, the cable 510 includes a network cable and a power cable, which separates the data transmission and power transmission between the control component 500 and the camera 210, making it easier to perform separate maintenance and repairs later.

[0058] In other embodiments, cable 510 is a network cable using Power over Ethernet (POE), which allows for simultaneous data and power transmission between control component 500 and camera 210 without the need for additional power cables.

[0059] In this embodiment, the cooling component 400 is a fan, which delivers high-pressure gas at room temperature to the insulation cavity.

[0060] In other embodiments, the cooling assembly 400 includes a heat exchanger and a fan, the fan delivering room-temperature high-pressure gas into the heat exchanger, and the cooled gas after water cooling heat exchange delivering low-temperature gas into the insulation cavity.

[0061] It is understandable that the control component 500 is electrically connected to the cooling component 600. Specifically, the detection component detects the temperature of the cooling gas, and the control component 500 can adjust the cooling effect of the cooling component 600 according to the detected temperature to ensure the protection effect of the cooling gas on the camera component 200.

[0062] In this embodiment, the refrigeration component 600 is connected to the heat insulation component 300, so that the outlet end of the refrigeration component 600 is connected to the inlet end of the heat insulation cavity, so that the cooled gas flows directly into the heat insulation cavity, reducing the heat loss of the cooled gas in the pipeline.

[0063] In this embodiment, the detection components are existing temperature and pressure sensors. The cooling component 600 is an existing vortex refrigerant tube. This invention does not improve the structure of the temperature sensor, pressure sensor, and vortex refrigerant tube; therefore, those skilled in the art should understand their specific structure and working principle, which will not be specifically explained here.

[0064] It is understood that the control component 500 can be a microcontroller, PCL controller, etc., capable of simply realizing data transmission and control of the cooling component 600. It should be noted that the control method of the control component 500 is not within the scope of this utility model and belongs to the prior art. This utility model mainly protects the connection method of the control component 500.

[0065] It is understandable that a filter 700 is provided between the cooling component 400 and the control component 500, such as Figure 1 and Figure 2 As shown, filter 700 is used to filter the cooling gas to prevent impurities in the cooling gas from being blown into camera assembly 200 and affecting the image quality of the image inside kiln 900 conveyed by camera assembly 200. Specifically, when the cooling gas contains impurities, the impurities can easily enter camera 210, affecting the electrical signals converted from optical images by camera 210; when impurities are blown into lens 220, they can cause black spots in the optical image formed by lens 220, affecting the image quality.

[0066] Understandably, both the inlet and outlet ends of the filter 700 are equipped with valves 710 for regulating the flow rate and pressure of the cooling gas, such as... Figure 2 As shown.

[0067] In this embodiment, the camera assembly 200 further includes a camera rod 230, which has a hollow first cavity 231, such as... Figure 3 As shown. The camera pole 230 extends horizontally, with one end of the camera pole 230 inserted into the kiln 900. The lens 220 is located at the end of the first cavity 231 that is inserted into the kiln 900. The other end of the camera pole 230 extends out of the kiln 900 and is connected to the camera 210. An electrical connection cable connects the lens 220 and the camera 210 inside the first cavity 231 to realize the transmission of optical images.

[0068] It is understandable that the first cavity 231 is connected to the cooling component 400, that is, the cooling gas output by the cooling component 400 is directly input into the first cavity 231 to cool the electrical connection wires and lens 220 located in the first cavity 231.

[0069] In this embodiment, the camera component 200 is an endoscopic camera.

[0070] In this embodiment, the heat insulation component 300 includes a heat insulation sleeve 310 and a heat insulation pipe 320. Specifically, the heat insulation pipe 320 extends horizontally, one end of the heat insulation pipe 320 passes through the kiln 900 and is embedded in the bricks and stones of the side wall of the kiln 900, so that the heat insulation pipe 320 and the bricks and stones are relatively fixed, and the other end of the heat insulation pipe 320 extends out of the kiln 900 and is connected to the heat insulation sleeve 310.

[0071] It is understood that the heat insulation sleeve 310 and the heat insulation pipe 320 form a heat insulation cavity. Specifically, the heat insulation cavity includes a second cavity 311 and a third cavity 321. The heat insulation sleeve 310 is hollow, forming the second cavity 311, and the camera 210 is installed inside the second cavity 311, such as... Figure 2As shown. The cooling component 600 and the heat insulation sleeve 310 are connected, that is, the air outlet of the cooling component 600 is connected to the second cavity 311, so that the low-temperature cooling gas delivered by the cooling component 600 cools the camera 210, as shown. Figure 2 As shown.

[0072] It is understandable that the heat insulation pipe 320 has a hollow cavity forming a third chamber 321, and the camera rod 230 is inserted into the third chamber 321, such as... Figure 3 As shown. The cooling assembly 400 is connected to the third chamber 321, allowing cooling gas to cool the camera rod 230. The third chamber 321 is connected to the interior of the kiln 900 and is provided with an air outlet 330. The cooling gas, after cooling the camera rod 230, is delivered into the kiln 900 through the air outlet 330, so that the cooling gas acts as an air curtain, preventing hot air from the kiln 900 from entering the third chamber 321 through the air outlet 330, which could cause the hot air from the kiln 900 to heat and damage the lens 220 and its electrical connection cable with the camera 210.

[0073] In some embodiments, the cooling assembly 400 can be connected to the first cavity 231, the third cavity 321 and the filter 700 respectively via a four-way valve, so that the cooling gas output by the cooling assembly 400 is diverted into the first cavity 231, the third cavity 321 and the filter 700.

[0074] In this embodiment, the cooling assembly 400 is connected to the first cavity 231, the third cavity 321, and the filter 700 via the first connector 810 and the second connector 820, respectively. Figure 2 As shown. Specifically, the first connector 810 is connected to the cooling assembly 400, the third chamber 321, and the second connector 820, respectively, so that the cooling gas output from the cooling assembly 400 is diverted through the first connector 810 to the third chamber 321 and the second connector 820. The other two ends of the second connector 820 are connected to the first chamber 231 and the filter 700, respectively, so that the cooling gas entering the second connector 820 is diverted to the first chamber 231 and the filter 700.

[0075] It is understandable that both the first connector 810 and the second connector 820 are tees.

[0076] Thus, the visual device 100 also includes a first conduit 830, a second conduit 840, and a third conduit 850. Specifically, the first conduit 830 connects to the second connector 820 and the first cavity 231. The second conduit 840 connects to the second connector 820 and the second cavity 311, and the filter 700, control component 500, and cooling component 600 are all disposed on the second conduit 840. The third conduit 850 connects to the first connector 810 and the third cavity 321.

[0077] Understandably, the visual device 100 also includes an alarm component 520, which is electrically connected to the control component 500. Specifically, the control component 500 has a preset temperature. When the temperature of the cooling gas passing through the control component 500 is higher than the preset temperature, the alarm component 520 is activated, prompting the worker to adjust the cooling effect of the cooling component 600 to prevent the ambient temperature from being too high, which would cause the input cooling gas temperature to be too high and affect the cooling effect of the cooling gas on the camera component 200.

[0078] Furthermore, the alarm issued by the alarm component 520 can also be transmitted to the display component via the control component 500, making it convenient for workers to remotely adjust the cooling effect of the cooling component 600 based on the temperature detected by the temperature sensor.

[0079] Understandably, the control component 500 has a preset air pressure. When the pressure of the cooling gas passing through the control component 500 is higher or lower than the preset air pressure, the alarm component 520 is activated, prompting the worker to adjust the valve 710 of the filter 700 to prevent the air pressure in the second chamber 311 from being too high, which would affect the normal operation of the camera 210; and to prevent the air pressure in the second chamber 311 from being too low, which would affect the cooling effect of the cooling gas on the camera 210.

[0080] Furthermore, valve 710 is electrically connected to control component 500, allowing the opening and closing of valve 710 to be adjusted via control component 500. Alarms issued by alarm component 520 can also be transmitted to display component via control component 500, facilitating remote adjustment of valve 710's opening and closing by operators based on the air pressure detected by the air pressure sensor.

[0081] Understandably, the alarm component 520 can be a warning light or horn to alert on-site workers to adjust the refrigeration component 600 or valve 710 via light or sound.

[0082] Furthermore, warning lights can be installed on the control panel 530.

[0083] like Figure 1 As shown, the kiln 900 of this utility model embodiment includes a roller 910 and a viewing device 100. The roller 910 conveys ceramic tiles 920 inside the kiln 900. The viewing device 100 is arranged along the side wall of the kiln 900. The lens 220 is located above the roller 910, so that the lens 220 can perform optical imaging on the ceramic tiles 920 located above the roller 910.

[0084] It is understood that the camera assembly 200 can be a top-view type, a ball valve type, etc. In this embodiment, the camera assembly 200 is a front-view type.

[0085] Furthermore, at least two visual devices 100 are provided and are respectively arranged on two opposite side walls of the kiln 900, so that at least two camera components 200 respectively perform optical imaging on the tiles 920 on the left and right ends of the roller 910, which makes it easier for workers to accurately and completely view the direction of the tiles 920 on the roller 910 through at least two optical images.

[0086] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
