Keeper is provided with clean door.
In above-mentioned industrial explosion-proof fan, back shroud is provided between described spiral case and motor, described motor is fixed
In on back shroud, and described back shroud is connected by screw or bolt with spiral case.
In above-mentioned industrial explosion-proof fan, support bar is installed between described motor and spiral case, described support bar leads to
Cross screw or bolt is fixed.
In above-mentioned industrial explosion-proof fan, the bottom of the spiral case is provided with the support sole for fixing spiral case, described
Support sole fixed and be connected with spiral case by screw or bolt.
Compared with prior art, this industrial explosion-proof fan has advantages below：
1st, screen pack is provided with the outer face of air inlet, solid particulate matter larger in air-flow can be stopped outside
On side, air inlet the inner the shred holding up plate that sets can by gas relatively in less solid particulate matter stop, prevent and run at high speed
Impeller is collided, and improves safety coefficient.
2nd, wind guide vane is installed in air inlet, makes air-flow more easily collecting, and can prevent solid particulate matter in air-flow from
Enter impeller in the gap of shred holding up plate.
3rd, the protective layer set on wind guide vane and deep bead can weaken the shock dynamics of the solid particulate matter in air-flow, and
It can prevent collision from producing spark.
4th, the bottom of spiral case is provided with cleaning door, can periodic cleaning spiral case inner accumulation solid particle material, also can be right
Impeller is cleaned, and is easy to cleaning.
5th, motor is fixed on spiral case by support bar, is reduced material and is not interfered with the stability of motor, reduces
Production cost.
