Detailed ways

The preferred examples of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred examples described here are only used to illustrate and explain the present invention, and do not limit the present invention.

It should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner" and "outer" are based on the orientations or positional relationships shown in the drawings. The positional relationship is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the referred position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

What shown in Fig. 1 is a kind of embodiment of the present utility model.

As shown in Figure 1, a coal plant belt machine head belt working surface cleaning and dust removal cleaner is arranged at the belt conveyor. Specifically, the utility model is provided with a material sensing device 8 at the belt conveyor, and the material sensing device 8 is used to detect whether there is material on the belt conveyor;

There are multiple rows of nozzles facing the belt below the coal throwing steering position of the belt conveyor head. The nozzles close to the running direction of the belt are connected to the Fengshui mixer 2, and the nozzles close to the running direction of the belt are connected to the high-pressure water pipe and the Fengshui mixer 2. Connected to high-pressure water pipes and high-pressure air pipes;

The first solenoid valve 5 of the high-pressure water pipe and the second solenoid valve 6 are arranged on the high-pressure air pipe. The first solenoid valve 5 and the second solenoid valve 6 are connected to the PLC control box 7; the PLC control box 7 is connected to the material sensing device 8.

It also includes an air-drying nozzle, which is connected to the high-pressure air pipe, and the air-drying nozzle is in the direction of the end of the nozzle, facing the belt.

The turning position of the head of the belt conveyor is provided with a dust suppression cover 9, the nozzles and air-drying nozzles are in the dust suppression cover, and the waste water collection box is below the dust suppression cover, and the waste water collection box leads into the underground wastewater recovery pipeline.

A belt brush is also arranged between the two rows of nozzles, and the belt brush contacts the belt surface. The outer diameter of the high-pressure air pipe 3 is 50 cm, and the inner diameter of the high-pressure water pipe 4 is 20 cm.

The utility model has the advantages of simple structure, low cost, flexible layout, small water consumption, small occupied area and convenient operation.

The utility model has higher economic efficiency, realizes two functions of cleaning the belt and reducing dust, eliminates the phenomenon of large coal dust at the head of the belt machine, controls environmental pollution, and ensures the safety and health of employees. At the same time, it reduces the labor intensity of workers and makes outstanding contributions to the construction of a safe and efficient green coal preparation plant.

Working principle: When there is material on the belt, the material sensing device 8 receives the signal and transmits it to the PLC control box 7, and the PLC control box 7 sends a signal to open the first solenoid valve 5 and the second solenoid valve 6, at this time the air-water mixer 2 The high-pressure water pipe 4 and the high-pressure air pipe 3 produce mist water, which forms a uniform fan-shaped spray surface through the nozzle 1, cleans the dust and coal particles on the belt through the high-pressure water mist, and then cleans the belt through the belt brush, and finally sprays high-pressure water from the nozzle cleaning. And the belt surface is dried by high-pressure air at the air-drying nozzle to avoid dust adhesion. The mist water produced by the utility model contacts and collides with the dust particles produced by the belt conveyor at the same time, and settles under the action of its own gravity, so as to achieve the effect of dust suppression. Finally, the water machine dust flows into the waste water collection tank for treatment and reuse.

The utility model wets the surface of the belt by spraying water mist at the near end of the reprint, and at the same time sprays and absorbs dust particles, then removes large particles through the belt brush, then uses water to wash away the surface particle dust, and finally removes water by air drying. Multi-step to achieve the purpose of cleaning and dust reduction on the belt working surface of the belt machine head. Compared with direct spray dust removal or cleaning belt conveyor, the effect is better.
