As shown in fig. 1 and 2, in some examples, the filter element 3 is removably attached to the housing 1. That is, the filter element 3 is required to be mounted so as to be easily disassembled, so that the filter element 3 can be inspected manually at regular time and cleaned deeply, and impurities firmly adhered to the filter element 3 can be removed.

For example, when the filter element 3 is positioned at a position of the casing 1 near a port or the like where the disassembly is convenient, the filter element 3 may be attached to the casing 1 by bolts, so that the stability of the structure thereof may be ensured, and the work of workers may be facilitated.

As shown in fig. 2, in some examples, a first notch 11 is formed in a side wall of the housing 1, the filter component 3 includes a filter screen 31 and a mounting plate 32, the filter screen 31 is connected to the mounting plate 32, the filter component 3 is inserted into the housing 1 through the first notch 11, the mounting plate 32 is clamped in the first notch 11, or the mounting plate 32 is propped against an outer wall surface of the housing 1.

It should be noted that, in order to place the filter element 3 at a suitable position, the filter element 3 is usually located at a relatively deep position inside the housing 1, and if the disassembly and replacement of the filter element 3 is difficult to be performed directly from the port of the housing 1, and the ventilation device needs to stop running for a long time, the ventilation effect on the mine is large, and the first notch 11 is formed in the housing 1, so that the filter element 3 can be inserted through the first notch 11, thereby greatly improving the working efficiency.

Optionally, the first notch 11 is formed in the upper half of the housing 1, so that after the filter element 3 is inserted into the housing 1, the filter element 3 and the first notch 11 can be stably assembled by using the gravity of the filter element and the clamping relationship between the filter element and the first notch 11, and the auxiliary fixing can be performed by using bolts.

As shown in fig. 1, in some examples, an ear plate 16 is provided on a side wall of the housing 1, the ear plate 16 being used to mount a ventilation device.

When carrying out ventilation unit's installation, because mine environment is abominable, need plan to ventilation unit's installation, for example through driving into the support on the wall in mine tunnel, through support installation ventilation unit, can carry out bolted connection with the support through otic placode 16 on the casing 1 this moment, it is comparatively convenient during the installation.

As shown in fig. 1, in some examples, a protective screen 17 is also included, the protective screen 17 being provided at both the first port 14 and the second port 15.

Because the mine environment is complicated, large-particle ores or massive materials exist, equipment is damaged after entering the ventilation device, the fan blades 21 cannot rotate or even are scrapped when serious, other safety accidents can be induced, and therefore the protective net 17 is required to be arranged to block external large-particle impurities.

As shown in fig. 2 and 3, in some examples, the airflow driving assembly 2 includes a fan 21 and a first driver 22, where the fan 21 is pivotally disposed in the housing 1 through a first rotating shaft 23, the first driver 22 is connected to the first rotating shaft 23, and the first driver 22 is used to drive the fan 21 to rotate.

Optionally, the first driver 22 may be a motor, for example, a dc motor, and a support frame 13 may be disposed in the housing 1, and a first shaft 23 is pivotally connected to the support frame 13, and the fan blade 21 is mounted on the first shaft 23 and drives the first shaft 23 to rotate by the first driver 22, so as to further realize the flow of the air flow in the housing 1.

As shown in fig. 2-4, in some examples, the dust collecting device further includes a dust collecting component 5, the dust collecting component 5 is connected to the housing 1, the dust collecting component 5 is correspondingly disposed below the filtering component 3, the dust collecting component 5 is used for collecting sundries cleaned from the filtering component 3, the housing 1 is provided with a second notch 12, the second notch 12 is disposed at the lower side of the windward side of the filtering component 3, the dust collecting component 5 includes a box 51 and a dust collecting box 52, the box 51 is connected to the housing 1, a side portion of the box 51 has a first opening, and the dust collecting box 52 is slidably disposed in the box 51 through the first opening.

That is, the foreign matter cleaned by the cleaning member 4 falls from the second notch 12 into the dust box 52, and the dust box 52 may be cleaned periodically. The cleaning frequency of the dust box 52 can be the same as the manual cleaning frequency of the filter element 3, so as to reduce the maintenance frequency and cost, and the second notch 12 can be arranged below the windward front side of the filter element 3, so that the cleaned sundries can be more conveniently scattered into the dust box 52.

As shown in fig. 2 and 3, in some examples, the cleaning member 4 includes a cleaning blade 41 and a second driver 42, where the cleaning blade 41 is pivoted in the housing 1 by a second rotating shaft 43, the cleaning blade 41 contacts the windward side of the filtering member 3, the second driver 42 is in driving connection with the second rotating shaft 43, the second driver 42 is used to drive the cleaning blade 41 to rotate, and the control member is used to control the opening and closing of the second driver 42.

In some examples, in the rotation direction of the cleaning blade 41, the cleaning blade 41 has a first end face 411 and a second end face 412, the first end face 411 is a concave arc face, and when the cleaning blade rotates, the first end face 411 is used for cleaning sundries on the filter element 3 and has a certain gathering effect, so that sundries are conveniently collected in the dust box.

Since the debris cannot remain in the windward region of the filter element 3 after being cleaned, the debris needs to leave the airflow channel, and the airflow is prevented from carrying the debris again to block the filter element 3. Therefore, the design of the arc-shaped surface of the cleaning blade 41 can have a gathering effect on sundries, so that the sundries cleaned are reduced from diffusing into the airflow channel, and dust collection is more convenient to realize.

As shown in fig. 2, in some examples, a support bracket 13 is further included, the support bracket 13 being disposed within the housing 1, the airflow drive assembly 2 and the cleaning member 4 being mounted on the support bracket 13.
