Embodiment Construction

[0014] Attached below figure 1 with figure 2 , To further explain the present invention:

[0015] Such as figure 1 As shown in this embodiment, the present invention includes an electric actuator, which is the main executive structure of the present invention. The electric actuator 6 is fixed on the chimney 8 by a bracket 12. The electric actuator It is an electric actuator 6 that can realize rotation output at any angle within the range of 0-90°. In this embodiment, the electric actuator produced by Shenzhen Jiashengyuan Electromechanical Equipment Co., Ltd. is selected. The specific parameters of the product are as follows: : JLY-05Z, output torque: 50N·m, driving mode: 220v AC; signal: 4-20mA, working range: 0-90 degree range, because the present invention requires the realization of the flue baffle 0-90 degree reversal. The electric actuator 6 is located below the flue baffle mechanism.

[0016] The flue baffle mechanism described in this embodiment includes a flue baffle sh...

Abstract

The invention relates to an actuator of a flue damper of a heating furnace, and belongs to a device matched with an oil field heating furnace for usage for regulating the atmosphere pressure in a combustion chamber, regulating the discharge flow of flue gas and controlling the temperature of exhaust gas. The actuator comprises an electric actuator, a connecting rod transmission mechanism driven bythe electric actuator and a flue damper mechanism driven by the connecting rod transmission mechanism. The flue damper mechanism comprises a flue damper shaft and a flue damper, wherein the flue damper takes the flue damper shaft as a rotating central shaft. The electric actuator is an electric actuator capable of realizing rotational output at any angle point within the range of zero to ninety degrees. A driving arm of a four-link mechanism is fixed on an output shaft of the electric actuator by screws, and a driven arm of the four-link mechanism is fixedly connected with the flue damper shaft. The actuator realizes full-automatic control of opening, closing and opening angles of the flue damper through the electric actuator and the transmission mechanism, has accurate control and can beused in combination with an existing integrated multifunctional burner.

Description

Technical field: [0001] The invention relates to a flue baffle actuator of a heating furnace, which belongs to a device for adjusting the atmospheric pressure in a combustion chamber, adjusting the flue gas discharge flow, and controlling the flue gas temperature, which is matched with an oil field heating furnace. Background technique: [0002] Reheating furnace is an important facility widely used in oil field production, and it is also the main energy-consuming equipment for oil and gas field development. The safe and stable operation of reheating furnace, emission reduction and efficiency increase are of great significance. [0003] Reasonable and stable combustion chamber atmosphere pressure, flue gas emission flow, and exhaust gas temperature control are the key links that determine the quality of combustion, whether the combustion is complete, the length of heat exchange, and the temperature of exhaust gas. It is the safe and stable operation of the heating furnace , An impo...
