Description
Technical field
The utility model relates to a kind of deduster explosion proof door, more particularly, relates to a kind of safety anti-explosive door with no pressure for suction type deduster.
Background technology
Sack cleaner is mainly used in trapping tiny, dry, non-fiber dust, can be divided into positive-pressure type deduster and suction type deduster according to its operating principle.Dust, in the upstream of deduster, is introduced in the deduster in downstream by blower fan by the assembling of positive-pressure type deduster, and in this case, the air pressure in deduster can be greater than ambient pressure; The assembling of suction type deduster, in the downstream of deduster, under the effect of blower fan, forms negative pressure in deduster, thus is sucked in deduster by dust.Due to deduster trapping is dust, and when dust concentration reaches certain condition, fully contacts, and can produce blast when running into the burning things which may cause a fire disaster such as spark, cause very large harm, therefore, sack cleaner is generally all provided with explosion-protection equipment with the oxygen in air.
At present; blast in deduster to tackle inflammable and explosive dust; protection deduster body; reduce the loss of exploding and bringing; common explosion precaution is: on the watch window of deduster, adopt explosion-proof lamp, and when the pressure in deduster reaches certain value, explosion-proof lamp can be first damaged; make pressure release in deduster, prevent deduster from exploding.But the shortcoming of this way is, occur that explosion-proof lamp breakage just needs again to change afterwards, as do not changed in time, deduster just cannot work at every turn, and impact is produced, and changes trouble, increases cost; And when pressure raises in deduster, if explosion-proof lamp could not be damaged in time, then deduster can be caused impaired, cause more losses.
Summary of the invention
1. the utility model technical problem that will solve
The purpose of this utility model is the above-mentioned deficiency overcoming existing deduster explosion-protection equipment, a kind of safety anti-explosive door with no pressure for suction type deduster is provided, adopt the technical solution of the utility model, when deduster normally works, utilize the suction function in explosion-proof every body self gravitation and deduster, make explosion proof door be in closed state; Pressure occurs in deduster when raising and exceed setting pressure, door body can be pushed open by pressure in deduster automatically, realizes quick pressure releasing in deduster, and can automatically close at pressure release back door body, reduces dust and leaks, still can drop into normal use after pressure release; This safety anti-explosive door with no pressure is simple, is quick on the draw, safe and reliable, greatly reduces the loss brought because of dust explosion.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:
A kind of safety anti-explosive door with no pressure for suction type deduster of the present utility model, comprise doorframe, Men Ti, hinge and sealing mat, described doorframe is installed on deduster, the upper end of described door body is installed on the upper end of doorframe by hinge, the lower end of described door body is unsettled, and Men Tike is freely rotated around hinge, and described sealing mat is installed on the surrounding of doorframe, when door body closes, Men Tiyu doorframe seals by sealing mat.
Further, described door body is also provided with observation port.
3. beneficial effect
The technical scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
A kind of safety anti-explosive door with no pressure for suction type deduster of the present utility model, when deduster normally works, utilizes the suction function in explosion-proof every body self gravitation and deduster, makes explosion proof door be in closed state; Pressure occurs in deduster when raising and exceed setting pressure, door body can be pushed open by pressure in deduster automatically, realizes quick pressure releasing in deduster, and can automatically close at pressure release back door body, reduces dust and leaks, still can drop into normal use after pressure release; This safety anti-explosive door with no pressure is simple, is quick on the draw, safe and reliable, greatly reduces the loss brought because of dust explosion.
