Chute blockage detector

Abstract

The invention discloses a chute blockage detector and particularly relates to the field of detection equipment. The chute blockage detector comprises a main plate; a main base is arranged at the top of the main plate; the main base and the main plate are integrated; a back cover plate is arranged at the back of the main base; a sensor protective cover is arranged at the top of the back cover plate; a sensor is arranged in the sensor protective cover; a rotating main shaft is arranged in the main base; main shaft bearing pedestals are arranged on the two sides of the main base; the rotating main shaft is connected with the main shaft bearing pedestals; an action position positioning rod is arranged in the main base; reset springs are arranged at the two ends of the rotating main shaft; a limiting reset baffle is arranged on one side of the internal part of the main base; the rotating main shaft is welded with a movable push plate; and the back side of the movable push plate is welded with an induction block. Through the rotating main shaft, the reset springs, the positioning rod, the reset baffle, the push plate and a proximity switch, when a blanking cylinder chute is blocked, the stacked materials extrude the movable push plate in the blockage detector, the movable push plate is offset by a certain angle by a thrust, the induction block at the back triggers the proximity switch, the proximity switch sends out a warning or stopping signal to a work pre-warning end to remind staff and the next detection work can be conducted continuously, so that the chute blockage detector guarantees that the materials are not stacked in the detector and can be widely applied to industries such as grains, electric power, coal, cement and petrochemistry.

Description

technical field [0001] The present invention relates to the technical field of detection equipment, and more specifically, the present invention relates to a chute clogging detector. Background technique [0002] The chute is a closed cylinder transfer channel that transfers the mined ore material to the next conveyor belt through belt conveyor. It is mainly used in food, electricity, coal, cement and petrochemical industries. The longitudinal slope of the channel is larger than the natural repose angle of the ore rock, generally 40-55°, and the channel length ranges from tens of meters to more than 100 meters. slip volume. When the chute is used alone, a reloading device is provided at the lower part of the channel, and loading equipment can also be used. [0003] The existing chute still has many disadvantages during use, such as frequent blockage of the chute, which will affect the continuous operation of the equipment after the chute is blocked, easily cause damage to...

Problems solved by technology

[0003] The existing chute still has many disadvantages during use. For example, chute blockage often occurs. When the chute is blocked, it will affect the continuous operation of the equipment, easily cause damage to the equipment, and reduce work efficiency at the same time.
