[0002] Phosphate mine ventilation is an important equipment used in phosphate mines. It is mainly used to provide necessary ventilation, ensure air circulation in the mine, reduce the concentration of harmful gases such as gas, and thus prevent dangerous situations such as gas explosions. This ventilation device usually includes mining axial flow fans and other related equipment.

[0003] Axial flow fans for mining are the main components of phosphate mine ventilation devices. Their main function is to introduce fresh air into the mine and discharge dirty air and harmful gases in the mine. This type of fan is usually installed at the entrance or key parts of the mine to ensure air circulation in the mine. In addition to axial flow fans for mining, phosphate mine ventilation devices may also include other equipment, such as ventilation ducts, dampers, wind windows, etc. These devices work together to ensure unimpeded air circulation in the mine, thereby protecting the lives of miners. Phosphate mine ventilation devices are an indispensable part of phosphate mine production, and their normal operation is of great significance to protecting the lives of miners and improving production efficiency. Therefore, when selecting and using phosphate mine ventilation devices, it is necessary to fully consider the actual situation and needs of the mine, select suitable fans and supporting equipment, and perform regular maintenance and inspections to ensure their normal operation.

[0004] The existing phosphate mine ventilation device usually only ventilates or filters during use. If the air is ventilated and filtered at the same time, more driving devices are required to ventilate and filter the air, but there are problems of high energy consumption and low efficiency, which cannot meet the needs of phosphate mining. To this end, we provide a high-efficiency and energy-saving phosphate mine ventilation device. Utility Model Content

[0008] A further technical improvement of the utility model is that: a plurality of annular grooves are arranged on the installation tube, a sliding block is arranged on the outer side of the rotating ring, and the rotating ring is rotatably connected in the annular groove through the sliding block.

[0009] A further technical improvement of the utility model is that the driving member includes a driving rod and a driving motor, the driving rod is rotatably connected in the mounting cylinder, and the driving rod is located in the mounting cylinder, the driving rod is connected to the rotating ring through a plurality of connecting rods, the driving motor is arranged on the mounting cylinder, and the output shaft of the driving motor is connected to the driving rod.

[0010] A further technical improvement of the utility model is that the ventilation member includes a plurality of fan blades and a mounting block, the mounting block is fixedly sleeved outside the driving rod, the plurality of fan blades are mounted on the mounting block, and the plurality of fan blades are evenly arranged around the axis of the driving rod.

[0011] A further technical improvement of the utility model is that a connecting cylinder is provided at the bottom of the installation cylinder, and a wool-like filter layer is detachably installed on the inner wall of the connecting cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The device drives a driving rod to rotate through a driving motor, and the driving rod drives the mounting block and a plurality of fan blades to rotate, thereby driving the airflow to pass through the connecting tube and the mounting tube in sequence. When the airflow passes through the connecting tube, the wool-like filter layer in the connecting tube performs preliminary filtration on the dust in the airflow. When the airflow reaches the mounting tube through the connecting tube, a plurality of spiral filter screens filter the dust in the airflow again.
