Vertical shaft explosion door Product Introduction

Vertical shaftexplosion door is used for vertical well head wind, when the fan to stoprunning, explosion door automatically rises. When disasters in mines,explosion-proof door opens automatically, releasing energy, which protect thefan from damage.

Vertical shaft explosion door Structure

It consists ofexplosion-proof cover, the wind device, a heavy hammer device and other parts.         

1、the structure of the explosion-proofcover by cone is divided into four parts connected, each part by steel plate,Angle steel compound forming

2、back to the wind device for thepressure plate type          

3、heavy hammer device consists of a heavyhammer, pulley,counterweight         

4、the sealing method using welding steelouter panels fixed δ15rubber       

Vertical shaft explosion door Parameters

Mostare based on shaft diameter selection, and its ability to adapt to differentsuction fan. According to the negative pressure fan can be divided into no morethan 350 mm watercolumn and not greater than 450 mmwater column two categories; According to the mouth of the well diameter pointshave three specifications: maximum fan pressure of 4.413 KPa.

Vertical shaft explosion door Notices

1、Choose fan negative pressure within thescope of the maximum vertical wind Wells explosion door to avoid risk valuenegative pressure condition.        

2、According to the actual need toincrease or decrease in weight to ensure that the automatic rises when the fanstop explosion door check regularly.       

3、The choice of sealing medium can alsouse oil or oil/water mixture, water seal can be used in don’t frozen areas
