Description

Technical Field

[0001] The utility model relates to the technical field related to ventilators, in particular to an adjustable mining ventilator. Background Art

[0002] In the existing technology, a mine ventilator is a tool used in the mining industry. Since the working environment in the mine is dark and humid and very prone to accidents such as explosions, mines need fans to carry out related work to ensure the safety of underground work. The main function of a mine fan is to deliver enough fresh air to the underground to supply the oxygen needed for breathing for underground personnel.

[0003] Reference is made to a patent application with publication number CN116558003B, which discloses an adjustable mining ventilator. The ventilator uses a water pump to spray water in a circulating water tank through a sprinkler head onto a shuttle-shaped regulating body. The shuttle-shaped regulating body serves as an attachment for water evaporation. When water flows over its surface, a water film is formed. When air blows through the shuttle-shaped regulating body, the water evaporates into the air, thereby increasing the humidity.

[0004] The above-mentioned fan can humidify the gas through the cooperation of the spray head and the shuttle-shaped regulating body. However, the fan uses the spray head to spray liquid in a fixed manner to control the humidity. Its spraying position is too single and cannot be freely adjusted according to the humidification needs, resulting in uneven gas humidification effect, affecting the humidification effect and being unfavorable to the operation of the fan.

[0025] like Figure 2 and Figure 5As shown, the adjustable humidifying mechanism includes an annular track 2, which is detachably mounted on one side of the inner wall of the ventilation channel 101, and a plurality of sliders 3 are slidably engaged in the annular track 2, and a humidifying nozzle 4 is detachably mounted on the plurality of sliders 3. A plurality of through holes 5 are provided in a circular array on the annular track 2, and a plurality of sliders 3 are slidably penetrated with a reinforcing bolt 6, and the reinforcing bolt 6 on each slider 3 passes through the through hole 5 to limit the slider 3 on the annular track 2, and an annular cavity 7 is installed in the ventilation channel 101 on one side of the annular track 2.

[0026] When adjusting the humidification position: by providing an adjustable humidification mechanism, multiple humidification nozzles are fixed on the annular track through sliders, thereby forming a multi-point distribution in the ventilation channel. Subsequently, synchronous multi-point spraying and atomization can be completed in the ventilation channel, making the overall atomization humidification more uniform and avoiding dead corners.

At this time, the slider can drive the humidification nozzle to move within the restriction of the annular track, thereby obtaining position adjustment, which is convenient for free adjustment according to humidification needs. After the adjustment is completed, the reinforcement bolts can be passed through the through hole to lock it.
