[0025] This utility model proposes an electric rotary furnace flame monitoring system, aiming to design an electric rotary furnace flame monitoring system that allows the optical imaging lens tube to rotate according to on-site needs, achieving the effect of observation from different angles.

[0026] The electric rotary furnace flame monitoring system proposed in this utility model will be described below in specific embodiments:

[0027] In the technical solution of this embodiment, such as Figure 1 As shown, an electrically operated rotary furnace flame monitoring system includes:

[0028] Drive motor 1;

[0029] Rotating mechanism 2 is connected to drive motor 1 via gear transmission mechanism;

[0030] The optical imaging lens tube 3 is coaxially fixed on the rotating mechanism 2, with its extended end facing the inside of the furnace.

[0031] A high-temperature endoscope is sealed and embedded in the furnace side end of the optical imaging tube 3;

[0032] Camera 4 is located at the end of the optical imaging tube 3 away from the furnace, and its lens is coaxially aligned with the optical output end of the high-temperature viewing mirror to form a continuous optical path.

[0033] Furthermore, the gear transmission mechanism includes a driving gear and a driven gear ring that mesh with each other, wherein the driving gear is fixed to the output shaft of the drive motor 1, and the driven gear ring is circumferentially fixedly fitted onto the outer wall of the optical imaging lens tube 3.

[0034] Furthermore, a heat insulation cavity is formed between the camera 4 and the high-temperature viewing mirror, and the heat insulation cavity is filled with high-temperature resistant heat insulation material.

[0035] Furthermore, the electric rotary furnace flame monitoring system also includes a remote control system, which comprises:

[0036] Decoder 51 is electrically connected to drive motor 1 and camera 4 respectively;

[0037] The central control room controller 52 and the decoder 51 are electrically connected to the central control room controller 52;

[0038] Among them, drive motor 1 is a stepper motor.

[0039] Working principle:

[0040] The operator can control the target rotation angle in the control room controller 52; the control room controller 52 sends a pulse signal, which is transmitted to the decoder 51 via optical fiber; the motor drive circuit of the decoder 51 outputs current to drive the stepper motor to rotate precisely the corresponding number of steps; the output shaft of the stepper motor drives the active gear to mesh with the driven gear ring, and transmits the torque to the optical imaging lens tube 3.

[0041] This utility model's electric rotary furnace flame monitoring system can observe the flame inside a boiler furnace from different angles, and is suitable for biomass boilers, etc. An endoscopic optical imaging system extends directly into the furnace, capturing the working status of each burner layer in the initial stage of ignition and the dynamic state of the combustion fireball after normal combustion. The images are then captured by a high-temperature endoscopic lens, converted into light signals by a camera, transmitted via fiber optic cable to the central control room, and finally displayed on a monitor, thus reflecting the overall combustion status of the flame inside the furnace.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
