Chute blockage preventing detection device for coal conveying system

Abstract

The embodiment of the invention discloses a chute blockage preventing detection device for a coal conveying system, and belongs to the technical field of pulverized coal conveying detection. The chute blockage preventing detection device comprises a fixed base, a movable door and a pin shaft, wherein the movable door is rotationally mounted on one side of the exterior of the fixed base; the pin shaft is mounted at the connecting position between the top end in the movable door and one side out of the fixed base in a penetrating mode, and the surface of the bottom end in the movable door is fixedly connected with one side of the outer wall of the fixed base through a driving mechanism. The driving mechanism comprises rotating worms, a movable supporting arm, a rotating hinge arm, a driving motor, a fixed gear ring and a transmission crawler belt, the rotating worms are symmetrically and rotatably mounted on two sides of the outer wall of the fixed base, and the rotating hinge arm is mounted at the connecting position of the top end of the outer portion of the movable supporting arm and the surface of the bottom end of the movable door in a hinged mode; the problem that an alarm signal is not sent after chute blockage of the device is solved. The device further prevents chute blockage and coal overflow to achieve a scientific detection effect.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of coal powder transportation detection equipment, in particular to a coal transportation system anti-blocking coal detection device. Background technique [0002] For power plants, the problem of coal congestion in the coal delivery system has been plaguing domestic and foreign power generation companies. In recent years, with the rapid development of social economy, the demand for power resources is also increasing, and the supply of coal for thermal power plants is increasing. Therefore, under the current situation, it is of great practical significance to strengthen the research on the problem of coal blocking in the coal conveying system of the power plant. [0003] The coal-falling pipe coal blocking detector of the original first-phase and second-phase coal conveying system of our factory is a rotary-resistant type, which is installed inside the coal-falling pipe of the belt...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides an anti-blocking coal detection device for coal conveying system to solve the problem that in the prior art, each component is affected by the above factors due to the internal environment of the coal falling pipe, such as humidity, dust, vibration, etc., and the equipment components It is relatively complicated, and the mechanical wear of the equipment is serious, which causes the actuator to refuse to act, which leads to the problem that the alarm signal is not sent after the coal is blocked.
