Abstract
The utility model discloses an anti-explosion fan with rubber at edges of fan blades. The anti-explosion fan comprises an anti-explosion motor and fan blades, wherein a filter net is arranged on an inlet of the anti-explosion fan, and a rubber sheath is arranged on the edges of the fan blades and is fixedly connected by using a fastening member. The anti-explosion fan has the advantages of simple structure, low cost, convenience in installation, good anti-explosion property, high reliability and wide application range.
Description
Technical field
The utility model relates to a kind of explosion-proof fan, especially relates to the explosion-proof fan that a kind of flabellum edge is provided with rubber.
Technical background
Have the place of inflammable gas at mine, industrial building etc., explosion-proof fan is used widely.
In order further to guarantee the safety of working environment, the explosion-proof technology research of explosion-proof fan seems particularly important.At present; The explosion-proof technology of explosion-proof fan generally focuses on the motor; Though do effectively to prevent on motor to produce electrical spark and flammable gas explosion takes place like this, do not take explosion-proof measure for the external structure of blower fan, when some solid particulate matter (like sand, iron filings etc.) entering blower fan; Can produce spark with the flabellum collision that runs up, thereby cause explosion risk to take place.Therefore, its explosion-proof effect still owes desirable.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, provides the better flabellum of a kind of explosion-proof effect edge to be provided with the explosion-proof fan of rubber.
The purpose of the utility model realizes through following technological scheme: a kind of flabellum edge is provided with the explosion-proof fan of rubber, comprises anti-explosion motor and fan leaf, and the ingress of said explosion-proof fan is provided with filter screen; The edge of said fan leaf is provided with rubber sheath, and is fixedly connected through fastening piece.
Further, said fastening piece can be rivet.
The utlity model has following advantage: filter screen is set up in the ingress of blower fan in (1); Can filter the larger particles material and make it not pass through blower fan; Thereby not only the use to motor shields, and can reduce because of collision and produce the possibility that spark sets off an explosion; (2) set up rubber sheath at the edge of fan leaf, like this, even have little particulate matter get into blower fan and with the fan leaf bump, can not produce spark yet.
In sum, the utility model can reduce the possibility that generation strikes spark in the blower fan to greatest extent, thereby improves its explosion-proof performance, guarantees the Security of working environment; In addition, the utility model need not on existing blower fan apparatus, to make big structural change, only needs the explosion-proof rubber sheath of configuration, filtration catch net in addition, and it is simple in structure, and is with low cost, easy for installation, and reliability is high, and is applied widely.
