Problems solved by technology

For the phosphate rock mined in adit, when the polluted air is generated in multiple working places, multiple mine ventilation equipment with the function of purifying the air are required to purify the polluted air in the air in order to meet the oxygen supply needs of the underground workers, and the cost is relatively high ; Moreover, the generation of polluted air is uncertain, and the ventilator is large in size and high in power, so it is not easy to move underground, and the purification effect is not ideal; at the same time, when the polluted air in one place is purified, short-term or long-term shelving of the ventilator will cause Waste of equipment resources

Embodiment 1

[0038] On the basis of the above-mentioned structure, in the present embodiment, the first-stage purification mechanism includes a purification cabin 3, and the interior space of the purification cabin 3 is separated from top to bottom by a partition into a purification cabin and a dust collection cabin connected to each other, and the dust collection cabin The bottom of the bottom is provided with a sewage outlet, and the welding method is adopted between the clapboard 1 and the purification cabin 3, and the purification cabin is preferably a conical purification cabin; the top of the purification cabin and the upper part of the side wall are respectively provided with a primary air outlet and a primary air inlet The air outlet, the primary air outlet is connected with the secondary purification mechanism through the pipeline. Under the action of the fan 2, the dirty air enters the purification cabin 3 from the primary air inlet. The dirty wind first enters the purification ca...

Embodiment 2

[0040] On the basis of Embodiment 1, in this embodiment, the primary air outlet is fixedly installed with a filter plate 4 for filtering the polluted air after the preliminary separation, and the filter plate 4 is installed in a manner conceivable by those skilled in the art At the air outlet and the air outlet, such as bolt connection, the filter plate 4 and the primary air outlet are respectively provided with screw holes matched with the bolts, which is easy to disassemble and replace the filter plate 4, saving time and effort. During purification, the primary purified dirty air is further filtered through the filter plate 4 to remove larger particles of harmful substances in the dirty air.

Embodiment 3

[0042] On the basis of Embodiment 1, in this embodiment, a monitor 5 for detecting the concentration of toxic and harmful substances in the polluted air is fixedly installed at the primary air inlet in a manner conceivable by those skilled in the art. During the walking process of the purification device, the concentration of toxic and harmful substances in the air is monitored by the monitor 5, and when the detected concentration is greater than the standard concentration, the air in the place needs to be purified.

[0043] It should be noted that the above-mentioned monitor 5 preferably adopts a concentration detection sensor, and the concentration detection sensor adopts the prior art.

[0044] In addition, a monitor can be installed in the cab, and the monitor 5 is connected to the monitor through a circuit, and the monitor 5 sends the concentration of the detected toxic and harmful substances to the monitor in real time, and displays it, which is convenient for the driver to...

Abstract

Th invention relates to a mobile phosphorus mine down-hole polluted air multi-stage purification device. The device comprises a mobile traveling frame, a first-level purification mechanism, a second-level purification mechanism, a third-level purification mechanism and a fan, wherein the first-level purification mechanism, the second-level purification mechanism, the third-level purification mechanism and the fan are installed on the traveling frame in sequence with pipes for communication. The mobile phosphorus mine down-hole polluted air multi-stage purification device has the beneficial effects that multiple stages of purification mechanisms are used for purifying polluted air, the purification effect is good, it can be implemented that the purification device can move down hole, and itcan be guaranteed that the working environment is good and healthy with purified air.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to a movable multi-stage purification device for underground sewage of phosphate mines. Background technique [0002] A good air environment is an essential condition for workers to work underground in phosphate mines. The main sources of air pollution in phosphate mines are dust containing phosphorus and nitrogen, as well as exhaust gas produced by transportation equipment and blasting during operation, so the underground air contains dust, carbon monoxide, hydrogen sulfide, nitrogen dioxide, etc., which are toxic and harmful. gas. When the toxic and harmful gases gradually increase, the oxygen concentration in the air will be relatively reduced. When the oxygen supply of underground workers is insufficient, adverse physiological reactions will occur, and various uncomfortable symptoms will appear. In severe cases, hypoxia may lead to death. Therefore, it has becom...
