Description
Technical field
The present invention relates to a kind of exhaust equipment, more specifically, it relates to the draught hood that a kind of globule will not drip.
Background technology
Draught hood connects with air exhauster, and the air in draught hood is taken in air exhauster work away, and then the air in draught hood lower zone can pour in draught hood, thus is taken away by air exhauster.The draught hood a certain degree of expansion of energy is by the area in convulsion region, thus preferably takes away in this region containing impurity, abnormal flavour or poisonous gas.
At present, draught hood on market includes cover body, as it is shown on figure 3, the cross section of cover body is isosceles trapezoid, around cover body, thin-walled surrounds air-breathing cavity, cover body open lower side, air exhauster is connected by exhaust column on the upside of air-breathing cavity, and air exhauster works, and gas enters from opening, gas is through the exhaust column that is guided into of faceshield side wall, thus by air exhauster suction exhaust gas treating tower.Such draught hood runs into sidewall at gas hot water and steam in sidewall, gas can be condensed into droplet, and droplet constantly collects party and drips from draught hood, can under the influence of the work of method, apparatus.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide the draught hood that a kind of globule will not drip.
For achieving the above object, the present invention adopts the following technical scheme that, including cover body, air-breathing cavity it is provided with in described cover body, described cover body lower ending opening, described air-breathing cavity connects with exhaust column, described opening part is provided with ventilative sponge, described ventilative sponge sidewall is fitted with cover body inwall, the affixed air permeable plate of described opening part, described air permeable plate is positioned at the top of ventilative sponge, described ventilative sponge is affixed with air permeable plate, described air permeable plate is provided with some equally distributed air-vents, it is provided with at least suction nozzle in described air-breathing cavity, described suction nozzle is provided with some suction holes, described suction nozzle one end connects with exhaust column, the other end is closed, described exhaust column is positioned at cover body side.
It is also preferred that the left be provided with collecting pipe between suction nozzle and exhaust column, described suction nozzle is three, and three described suction nozzle one end connect with collecting pipe respectively, and described exhaust column connects with in the middle part of collecting pipe.
It is also preferred that the left vent diameter is between 20mm to 40mm, the adjacent air-vent in described left and right is in staggered distribution.
It is also preferred that the left some suction holes are along suction nozzle length direction spread configuration, described suction hole is located close to ventilative sponge side.
It is also preferred that the left between a diameter of 20mm to the 40mm of described suction hole, at a distance of 100mm between described adjacent suction hole.
Hinge structure of the present invention is compared to be had: the gas below draught hood can first pass through the ventilative sponge of opening part, the hot water and steam contained in gas can be absorbed by ventilative sponge, by the suction nozzle in draught hood, gas is siphoned away the most again, the continuous air-breathing of suction nozzle, make gas constantly be sucked away through ventilative sponge, this ensure that the seriality that draught hood works so that draught hood will not produce the globule, affixed by ventilative sponge and air permeable plate, is so possible to prevent dropping of ventilative sponge.

Detailed description of the invention
Referring to the drawings draught hood embodiment of the present invention is described further.
A kind of draught hood, including cover body 1, it is provided with air-breathing cavity 11 in described cover body 1, described cover body 1 lower ending opening, described air-breathing cavity 11 connects with exhaust column 2, described opening part is provided with ventilative sponge 3, described ventilative sponge 3 sidewall is fitted with cover body 1 inwall, before gas wants air-breathing cavity 11, it is accomplished by first passing through ventilative sponge 3, hot water and steam in gas can be siphoned away by ventilative sponge 3 in advance, thus can avoid being formed the globule in cover body 1, the breathability that sponge 3 of simultaneously breathing freely has had, the entrance of gas will not be stopped, again by the continuous convulsion of suction nozzle 5, gas is constantly sucked away, so can guarantee that the seriality that draught hood works, thus avoid the globule to produce.
Also a certain degree of stretching can be had owing to ventilative sponge 3 is soft, if the most ventilative sponge 3 sidewall is affixed with cover body 1 inwall, the water that major part absorbs simultaneously that can sink in the middle part of ventilative sponge 3 is concentrated in the middle part of ventilative sponge 3, the most easily drip, for case above, the affixed air permeable plate of described opening part 4, described air permeable plate 4 is positioned at the top of ventilative sponge 3, ventilative sponge 3 is bonding with air permeable plate 4, it is so hard and surface opposed flattened due to air permeable plate 4, by air permeable plate 4 and cover body 1 affixed after, can effectively support ventilative sponge 3, make ventilative sponge 3 also relative level, water on ventilative sponge 3 is difficult to gather, do not have globule drippage.Described air permeable plate 4 can be to weld with cover body 1 or be bolted.Owing to air permeable plate 4 is arranged on the top of ventilative sponge 3, it is ensured that hot water and steam will not first encounter air permeable plate 4, thus avoids hot water and steam to be first condensed into the globule on air permeable plate 4 and drip.
Certainly, some equally distributed air-vents 41 can be provided with on described air permeable plate 4, whole air permeable plate 4 is as netted, so can effectively ensure good breathability, the most also the effect supporting ventilative sponge 3 can be played, further, between a diameter of 20mm to the 40mm of air-vent 41, it is preferably 30mm, the adjacent air-vent 41 in described left and right is in staggered distribution, and the comparison also leaned between the most adjacent air-vent 41 is tight, can be horizontal and vertical 50mm all apart, the distribution air-vent 41 so can gone up largely, more ensures the breathability of air permeable plate 4.
It is provided with at least suction nozzle 5 in described air-breathing cavity 11, described suction nozzle 5 is provided with some suction holes 51, described suction nozzle 5 one end connects with exhaust column 2, the other end is closed, so can effectively absorb the gas in cover body 1, being drawn in exhaust gas treating tower by gas, described exhaust column 2 is positioned at cover body 1 side, so can facilitate laying of suction nozzle 5.As preferably, collecting pipe 6 it is provided with between suction nozzle 5 and exhaust column 2, described suction nozzle 5 is three, three described suction nozzle 5 one end connect with collecting pipe 6 respectively, so can preferably ensure to absorb the gas in cover body 1, described exhaust column 2 connects in the middle part of collecting pipe 6, so can guarantee that in three suction nozzles 5, the size of suction is identical.Further, some suction holes 51 are along suction nozzle 5 length direction spread configuration, described suction hole 51 is located close to ventilative sponge 3 side, so can more conveniently absorb gas, can will siphon away through the gas of ventilative sponge 3 faster, between described a diameter of 20mm to the 40mm of suction hole 51, preferably 30mm, at a distance of 100mm between described adjacent suction hole 51, so can effectively ensure the efficiency of convulsion.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to the above embodiments, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
