Embodiment 1

[0046] The blocking monitoring device provided by the present invention can be installed in the head funnel of the belt transmission system to monitor whether the blocking phenomenon occurs in the head funnel, and can also be applied to other container devices prone to blocking. When in use, the blocking material monitoring device can be installed at the head funnel or the preset position of other container devices.

[0047] figure 1 A schematic diagram of the first structure of the material blocking monitoring device provided by the embodiment of the present invention is shown. Such as figure 1 As shown, the blockage monitoring device includes a shell with an open side, a magnetic induction proximity switch 10 , a transmission shaft 20 , and a detection baffle 30 . The inside of the housing is hollow, the transmission shaft 20 traverses the upper part of the housing, and is rotatably connected with the housing, and the magnetic induction proximity switch 10 is arranged on t...

Embodiment 2

[0072] Figure 13 A schematic structural view of the head funnel provided by the embodiment of the present invention is shown, as Figure 13 As shown, it includes a funnel body 100 and a blocking material monitoring device 200 as in Embodiment 1. The blocking material monitoring device 200 is arranged on the outer wall of the funnel body 100, and an opening is provided on the outer wall. The opening of the housing matches.

[0073] During the installation process, the plane where the flange 70 of the material blocking monitoring device 200 is located must be perpendicular to the horizontal plane. The material blocking monitoring device 200 cannot be installed at a position where it is impacted by material flow or splashed by large materials, nor can it be installed at a height where materials cannot reach when a material blocking failure occurs.

[0074] Preferably, the distance between each side of the opening and the flange side corresponding to the flange 70 is, but not l...

Embodiment 3

[0078] Figure 14 A schematic structural diagram of a transmission control system provided by an embodiment of the present invention is shown. Such as Figure 14 As shown, the transmission control system includes a belt conveyor 3000, a host computer 2000 and a head funnel 1000 as in the second embodiment. The host computer 2000 receives the alarm signal sent by the magnetic induction sensor 102 and controls the start and stop of the belt conveyor 3000 .

[0079] The host computer 2000 may be, but not limited to, a PLC (Programmable Logic Controller, Programmable Logic Controller), DCS (Distributed Control System, Distributed Control System) or a single-chip microcomputer.

[0080] During the use of this embodiment, when a material blocking fault occurs, the material level reaches the height of the detection baffle, and the detection baffle rotates under the push of the material, and drives the transmission shaft to rotate; when the magnetic induction proximity switch detect...

Abstract

The invention provides a blockage monitoring device, a head hopper and a transmission control system. The blockage monitoring device comprises a shell with an opening in one side face, a magnetic induction proximity switch, a transmission shaft and a detection baffle. The shell is hollow, the transmission shaft transversely penetrates through the upper portion of the shell to be rotationally connected with the shell, the magnetic induction proximity switch is arranged on the outer side of the shell, the detection baffle is arranged in the opening of the shell, one end of the detection baffle is fixed to the transmission shaft, and therefore the detection baffle is rotated to drive the transmission shaft to rotate. After the magnetic induction proximity switch detects rotation of the transmission shaft, an electrical circuit is controlled to be disconnected or connected. According to the blockage monitoring device, the problem that an existing detection device cannot adapt to the poor production environment of a coal conveying system, and belt conveyor blockage faults cannot be accurately and reliably detected is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical design and manufacture, in particular to a material blocking monitoring device, a head funnel and a transmission control system. Background technique [0002] The belt conveying system is an important public system of a thermal power plant. The raw coal conveying system of a thermal power plant is composed of multiple belts and equipment such as screening, coal feeding, and coal blending. Remote control only from the control room. If a coal blocking failure occurs during the operation of the conveying system, the detection and signal upload cannot be performed in a timely and accurate manner, which will cause a large amount of raw coal to accumulate and break the belt. When a belt is worn out, the motor is still running, which will continue to cause the raw coal of the upper belt to accumulate and wear the belt, so that the entire conveying system is paralyzed, and the consequences are very se...
