Embodiment 1

[0025] see figure 1 and 3 , an automatic flushing system for a coal trestle, comprising a double-belt unit 1, a belt conveyor corridor 2 is arranged in the middle of the double-belt unit 1, a double-belt conveyor main pipe 3 is installed above the belt conveyor corridor 2, and a double-belt conveyor main pipe 3 is installed on the top of the belt conveyor corridor 2. Both sides of the pipe 3 are connected with two groups of branch pipes 4, and the ends of the branch pipes 4 are equipped with a water nozzle 5 through a quick connector female head. The opening angle direction of the water nozzle 5 corresponds to the leg of the double belt unit 1 perpendicular to the ground.

[0026] Find through the research of the present invention, if main pipe 3, branch pipe 4 inner diameters are too large then easily cause the waste of water source, main pipe 3, branch pipe 4 inner diameters are too small then flushing efficiency is low, therefore, the inner diameter of double belt conveyor ...

Embodiment 2

[0032] see figure 2 and 3 , an automatic flushing system for a coal trestle, comprising a single-belt unit 11, one side of the single-belt unit 11 is provided with a belt conveyor gallery 2, and a single-belt conveyor main pipe 31 is installed above the side wall of the belt conveyor gallery 2; The upper connection branch pipe 4 of belt conveyor main pipe 31, the end of branch pipe 4 is equipped with water nozzle 5 by quick connector female head, and the opening angle direction of water nozzle 5 is corresponding to the support leg perpendicular to the ground of single belt unit 1. Also be provided with electromagnetic valve on branch pipe 4, electromagnetic valve is interlocked with belt motor, is convenient to automatic control, saves water. A shut-off valve is also arranged on the main pipe 31, and the shut-off valve is used to control the size of the water flow. Further preferably, the branch pipe 4 is vertically connected to the main pipe 31, such a design increases the...

Embodiment 2

[0033] In embodiment 2, parameters such as the inner diameter of the main pipe and the branch pipe, the height of the main pipe from the ground, the distance between it and the double-belt unit, the width and opening angle of the nozzle of the water nozzle adopt the same preferred settings as in embodiment 1.

[0034] The coal conveying trestle automatic flushing system, from the head of the single-belt unit 11 to the first flushing through the water nozzle 5, can clean the aisle in the middle of the belt conveyor according to the order from the head to the tail, and can clean the belt conveyor. Sweep all the dead corners at the root of the outrigger to prevent dead corners from remaining, avoid repeated washing, and waste resources.

[0035] To sum up: the automatic flushing system of the coal conveying trestle sweeps all the dead corners of the legs of the belt conveyor through the water nozzle 5, reduces the work intensity of the workers on site, and avoids the safety hazard...

Abstract

The invention discloses an automatic washing system for a coal conveying viaduct. The automatic washing system for the coal conveying viaduct comprises two belt conveyors. A belt conveyor gallery is arranged between the two belt conveyors. A double-belt conveyor main pipe is mounted above the belt conveyor gallery. Branched pipes are connected to the double-belt conveyor main pipe. Water spray heads are mounted at the tail ends of the branched pipes. The opening angles and directions of the water spray heads correspond to the roots of supporting legs, perpendicular to the ground, of the two belt conveyors. According to the automatic washing system for the coal conveying viaduct, the two belt conveyors are washed downwards from the heads for the first time through the water spray heads, then the two sides of the first belt conveyor and the two sides of the second belt conveyor are sequentially washed, and in this way, the galley between the two belt conveyors can be completely washed; and dead corners of the roots of the supporting legs of the belt conveyors can be washed without being left, and resource waste caused by repeated washing is avoided.

Description

technical field [0001] The invention relates to the technical field of thermal power coal transportation, in particular to an automatic flushing system for a coal transportation trestle. Background technique [0002] The coal conveying system is a harsh workplace for coal-fired power plants. The coal conveying system of coal-fired thermal power plants produces a large amount of dust during coal unloading, coal crushing and operation; dust pollution seriously affects the workplace and the surrounding environment, not only causing dust pollution, and directly affect the physical and mental health of employees. Usually, in order to reduce dust, water is often added to the conveyor belt to remove dust, that is, water is added to the conveyor belt, but the effect is not obvious, because the belt is heavily loaded with water, and there is a lot of accumulated material, which is difficult to clean, which is not conducive to the operation of the belt. It also affects the service li...
