Description

Technical Field

[0001] This utility model relates to the technical field of kiln body observation devices, specifically to a high-temperature resistant kiln body observation device. Background Technology

[0002] In the operation of high-temperature kilns (such as rotary kilns, tunnel kilns, and shuttle kilns) in industries such as cement, metallurgy, ceramics, glass, and chemicals, real-time and direct visual observation of the kiln's internal conditions is crucial.

[0003] Chinese utility model patent with announcement number CN214032213U discloses a sealing door for an observation hole of a glass melting furnace, which includes "an insulation wall is provided on the outside of the observation hole of the glass melting furnace, a sleeve is provided on the insulation wall corresponding to the observation hole, a shell is provided on the outside of the sleeve, an insulation layer is filled between the sleeve and the shell, a sealing door covering one end of the sleeve is hinged on the shell, a lifting lug is provided on the sealing door, a cantilever is provided on the insulation wall, and a lifting device connected and cooperating with the lifting lug is provided on the cantilever";

[0004] However, the device uses a traditional open observation hole with a sealed door structure. This structure has strict sealing requirements. When the sealed door is opened under high kiln pressure, it is easy to leak fire. Moreover, it is easy to burn people when taking off and putting on the sealed door. It is inconvenient to observe and the image quality is poor. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant kiln observation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant kiln body observation device, including a kiln wall, a fixed metal frame is fixedly connected to the side wall of the kiln wall, the fixed metal frame is fixedly installed and connected to a fixed mounting plate by fixing bolts, and a sealing gasket is provided between the fixed metal frame and the fixed mounting plate.

[0007] The side wall of the fixed mounting plate is fixedly connected to an observation metal tube, the side wall of the observation metal tube is provided with a cold air pipe joint, and the end of the observation metal tube is fixedly installed with a fire observation hole cap.

[0008] The inside of the fire-viewing hole cap is equipped with a quartz glass lens.

[0009] The beneficial effects of this utility model are as follows: This device consists of a fixed metal frame welded to the side wall of the kiln and an observation metal tube welded to the fixed mounting plate. The observation metal tube is composed of a fire observation hole cap and a quartz glass lens inside. A cold air pipe connector is reserved on one side of the observation metal tube. This device not only avoids the problem of traditional open observation holes with sealed doors, which have strict sealing requirements and are prone to fire leakage and burns when opening and closing, but also solves the problem that the quartz glass lens of the observation hole without a cold air structure is easily blackened, making it impossible to clearly observe the situation inside the kiln.

[0010] To facilitate observation of the firing process inside the kiln:

[0011] The setting is further configured such that the fixed metal frame, the fixed mounting plate, and the sealing gasket are all connected to the observation metal tube.

[0012] By adopting the above technical solution, the firing situation inside the kiln can be directly observed through the quartz glass plate at the end of the metal tube, which is convenient for observation and use.

[0013] To achieve a clear view of the interior of the tube-rubbed kiln when observing through a quartz glass slide:

[0014] A further configuration is provided: the cold air duct connector is internally connected to the observation metal tube.

[0015] By adopting the above technical solution, cold air is introduced through the cold air duct interface during observation and use, thereby avoiding the problem of the quartz glass being blackened, which would prevent clear observation of the inside of the kiln.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0024] The inside of the fire observation hole cap 8 is equipped with a quartz glass lens 81.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the fixed metal frame 2, the fixed mounting plate 4, and the sealing gasket 5 are all connected to the observation metal tube 6.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the cold air duct connector 7 is internally connected to the observation metal tube 6.

[0027] The working process of this high-temperature resistant kiln body observation device is as follows:

[0028] The entire device is installed on the outside of the kiln wall 1 by fixing bolts 3 and fixing metal frame 2 through fixing mounting plate 4. A sealing gasket 5 is provided between fixing mounting plate 4 and fixing metal frame 2 to ensure the sealing effect of the device installation. During observation, the firing situation inside the kiln can be directly observed through the quartz glass lens 81 inside the observation hole cap 8. During observation, the inside and outside of the kiln are isolated to avoid the problem of fire leakage and burns.

[0029] During observation, cold air can be introduced into the observation metal tube 6 through the cold air duct connector 7, thereby avoiding the problem of the quartz glass lens 81 being blackened, which would prevent clear observation of the situation inside the kiln.
