Abstract
The utility model discloses an explosion-proof fan. The explosion-proof fan comprises an explosion-proof motor, blades, an air drum and supports. The supports are connected to the two sides of the outer wall of the air drum. The blades and the explosion-proof motor are arranged in the air drum side by side from front to back. The explosion-proof motor is connected with the blades through a bearing. A metal protection cover is arranged in front of the blades. A filter screen is installed between the metal protection cover and the blades. A shakeproof layer is arranged on the inner wall of the air drum. A heat insulation layer is arranged on the shakeproof layer. A silencer is arranged at the front end of the air drum. According to the explosion-proof fan, due to the arrangement of the shakeproof layer, the shakeproof effect is good; due to the fact that the heat insulation layer is arranged on the shakeproof layer, the phenomenon that the blades rub against the inner wall to generate sparks and cause explosion is avoided; due to the arrangement of the filter screen, large-grained ash layers can be filter away and prevented from entering the air drum to hit against the blades and generate sparks; due to the arrangement of the silencer, noise can be effectively removed.
Description
Technical field
The utility model relates to antiknock device field, specifically a kind of explosion-proof fan.
Background technique
Explosion-proof fan is to be applied in the higher place that needs again ventilation of combustable gas concentration, under coal mine, and boiler room etc.The technological requirement of explosion-proof fan is to avoid rotary component (draught fan impeller) as far as possible, can not produce spark, thereby the inflammable gas that ignites causes explosion phenomenon while there is friction with housing under special circumstances.Because explosion-proof fan is to be all applied to hazardous location, have unavoidably various collisions, therefore existing explosion-proof fan can be strengthened shockproof properties, and the explosion-proof fan of existing explosion-proof fan also needs to be strengthened further, explosion-proof fan can produce noise along with the rotation of rotary component in work, can effectively improve working environment.
Model utility content
The purpose of this utility model is the defect that overcomes above-mentioned prior art, provides a kind of explosion-proof shockproof properties good, and the explosion-proof fan that can effectively abate the noise.
The technical solution of the utility model is achieved in that a kind of explosion-proof fan, comprise anti-explosion motor, blade, air duct and support, it is characterized in that, described support is connected to the outer wall both sides of described air duct, before and after described blade and anti-explosion motor, be arranged side by side in described air duct, and described anti-explosion motor is connected with described blade by bearing, in described blade the place ahead, be provided with shelter-clad, between described protective housing and blade, filter screen is installed, on the inwall of described air duct, be provided with shakeproof layer, on described shakeproof layer, be provided with thermal-protective coating, the front end of described air duct is provided with a baffler.
Further, described blade adopts aluminum alloy material to make.
Further, described air duct adopts steel plate to make.
Further, described shakeproof layer adopts insulation rubber pad.
Further, described interlayer adopts fiber glass material.
On the utility model air duct inwall, be provided with shakeproof layer, when blower fan bumps, there is certain shockproof effect; On described shakeproof layer, be provided with thermal-protective coating, prevented that blade from directly contacting with air duct inwall, avoid blade and interior wall friction to produce spark, explosion-proof effect is good; Between blade and protective cover, be provided with filter screen, can filter the grieshoch of larger particles, avoid large particle grieshoch to enter in air duct, with blade, generation spark occurs to clash into; The front end of described air duct is provided with baffler, and the noise producing in the time of can effectively eliminating blower fan work, improves working environment.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of explosion-proof fan of the utility model.
Fig. 2 is the structural representation of a kind of explosion-proof fan shelter-clad of the utility model.
Fig. 3 is the structural representation of a kind of explosion-proof fan filter screen of the utility model.
Embodiment
Below in conjunction with accompanying drawing, concrete case study on implementation of the present utility model is illustrated:
As shown in Figure 1-Figure 3, a kind of explosion-proof fan, comprises anti-explosion motor 1, blade 2, air duct 3 and support 4, and wherein said blade 2 adopts aluminum alloy material to make, and described air duct 3 adopts steel plate to make.Described support 4 is connected to the outer wall both sides of described air duct 3, for supporting whole blower fan.Described blade 2 and anti-explosion motor 1 front and back are arranged side by side in described air duct 3, and described anti-explosion motor 1 is connected with described blade 2 by bearing 5, and described anti-explosion motor 1 can drive described blade 2 rotations.In described blade 2 the place aheads, be provided with shelter-clad 6; for the protection of described blade 2, avoid destroying; between described shelter-clad 6 and blade 2, one deck filter screen 7 is installed; described metal filter screen 7 can fall oarse-grained dust filtration, has avoided big dust particle to enter into described air duct 3 and has produced spark with described blade rubbing.On the inwall of described air duct 3, be provided with shakeproof layer 8, described shakeproof layer 8 adopts insulation rubber pad, has certain shockproof effect when blower fan bumps.On described shakeproof layer 8, be provided with thermal-protective coating 9, described thermal-protective coating 9 adopts fiber glass material, has avoided blade directly to contact with air duct inwall, avoids blade and interior wall friction to produce spark, and explosion-proof effect is good.The front end of described air duct 3 is provided with a baffler 10, and the noise producing in the time of can effectively eliminating blower fan work, improves working environment.
As described above, it is only preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, the simple equivalence of generally doing according to the utility model claim and model utility description changes and modifies, and all still belongs in the scope that the utility model patent contains.
