The utility model relates to a connecting air duct, in particular to an air duct for dust removal and moisture removal under negative pressure. A tapered air duct, the tapered air duct is composed of a tapered outer tube and an inner tube, with an air outlet and connecting parts at the upper end, a closed bottom end with a water guiding device, a cleaning port in the middle, and a cleaning port on the cleaning port. There is a cleaning door; the inner pipe is composed of a connecting pipe and an extension pipe, the inner pipe is inserted in the middle of the bottom end of the tapered outer pipe, the bottom of the connecting pipe is provided with an air inlet and connecting parts, and the extension pipe is arranged in the tapered outer pipe , the upper end of the extension tube extends to the cleaning port. When the utility model is in use, the tapered outer pipe is connected to the main air pipe of the centralized dust removal system, and the inner pipe is directly connected to the main air pipe of damp and loose cylindrical equipment. The initial dust and steam separation effect is achieved through the negative pressure difference in the tube formed by the diameter change in the tapered outer tube and the condensation effect of the tapered tube wall itself.
Description
Technical field
The utility model relates to a kind of connection airduct, relates in particular to the dedusting under suction function, the airduct of humidity discharging.
Background technique
In industrial production, a lot of moisture regain and loose equipment are arranged, this kind equipment often will relate to humidity discharging and dust removal apparatus.
In the throwing equipment of tobacco business, a lot of moisture regain and loose tube kind equipment are arranged, because the flue dust that tobacco leaf self is produced and the atomized water of moisture regain, it is particularly important that humidity discharging and dedusting just seem.And in this kind equipment, some is to carry out concentrated dust-removing by centralized dust-removing system, i.e. dedusting and humidity discharging have only an airduct, and flue dust and atomized water are inhaled in the dust pelletizing system by negative pressure together, following problem can occur:
1. atomized water sucks in the blower fan of dust pelletizing system by negative pressure, influences the working life of blower fan component;
2. cigarette ash tide and cause the ash discharge system jams of dust pelletizing system partially;
3. incrustation is on the high side in the airduct, reduces negative pressure in the airduct, influences dust removing effects, need often unpick and wash airduct;
4. in the incrustation condensed water is arranged, there is the refluence phenomenon in condensed water, influences the expanded cut tobacco quality.
So a kind of taper airduct of design makes its situation at concentrated dust-removing be issued to the effect of dirt, vapour separation.
Summary of the invention
In order to eliminate the equipment failure of the dust pelletizing system that moist cigarette ash causes, reduce the incrustation in the airduct, eliminate airduct blocking phenomenon and condensed water refluence phenomenon, the purpose of this utility model provides a kind of taper airduct, and the taper airduct reaches preliminary dirt, vapour separating effect.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of taper airduct, this taper airduct is made of taper outer tube and interior pipe, and the upper end is provided with exhaust outlet and connected element, and the bottom sealing also is provided with water guider, and the centre is provided with the cleaning mouth, and the cleaning mouth is provided with cleaning door; Pipe is made of connecting tube and extension tube in described, and interior pipe is plugged in the neutral position of taper outer tube bottom, and the connecting tube bottom is provided with intake grill and connected element, and extension tube is arranged in the taper outer tube, and the extension tube upper end extends to the cleaning mouth.
As further improved procedure, the internal diameter of above-mentioned extension tube upper end can prevent that less than the internal diameter of taper outer tube exhaust outlet condensed water from entering in the main equipment.
As further improved procedure, above-mentioned extension tube be shaped as taper shape.
As further improved procedure, above-mentioned connected element is a flange.
As further improved procedure, the outside of above-mentioned taper outer tube is provided with knocker, and cleaning door is provided with catching groove.But the cleaning door free switch, the inside of easy cleaning taper airduct, knocker guarantees the closed condition of cleaning door.
As further improved procedure, above-mentioned water guider is the conical hopper shape.
When the utility model used, the taper outer tube was connected with the air main of centralized dust-removing system, interior pipe directly be connected get damp again and the air main of a loose kind equipment on.Condensation by negative pressure difference and taper tube wall in the formed pipe of the reducing in the taper outer tube self reaches preliminary dirt, vapour separating effect.
Description of drawings
Fig. 1 is the utility model embodiment's a schematic representation.
Fig. 2 is the utility model embodiment's an internal structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
A kind of taper airduct as shown in Figure 1, this taper airduct is made of taper outer tube 1 and interior pipe 2, the upper end is provided with exhaust outlet 8 and flange 10, the water guider 6 of conical hopper shape is sealed and be provided with in the bottom, the centre is provided with cleaning mouth 7, cleaning mouth 7 is provided with cleaning door 3, and is provided with knocker 4 in the outside of taper outer tube 1, and cleaning door 3 is provided with catching groove 5.As shown in Figure 2, interior pipe 2 is made of connecting tube 12 and extension tube 11, and interior pipe 2 is plugged in the neutral position of taper outer tube 1 bottom, and connecting tube 12 bottoms are provided with intake grill 9 and flange 10.Extension tube 11 be shaped as taper shape, extension tube 11 is arranged in the taper outer tube 1, extension tube 11 upper ends extend to cleaning mouthfuls 7, the internal diameter of extension tube 11 upper ends is less than the internal diameter of exhaust outlet 8.
When using, taper outer tube 1 is connected with the air main of centralized dust-removing system, interior pipe 2 directly be connected get damp again and the air main of a loose kind equipment on.Above-mentioned device has following characteristics:
1, the reducing of taper outer tube 1 structure can make the interior negative pressure of airduct and the negative pressure of whole concentrated dust-removing main line there are differences, and negative pressure is less relatively in the taper outer tube 1, and the big pipe tobacco of the quality that adheres to atomized water is not inhaled in the airduct.
2, the interior wall energy of taper outer tube 1 makes the atomized water cooling that is drunk up by negative pressure, and condensed water flows in the water guider 6 by inwall and discharges.
When 3, flowing backwards appears in a spot of condensed water in the centralized dust-removing system air main, can flow to water guider 6 derivation of bottom along taper outer tube 1 inwall, as there being whose water to fall in the air main, because the path of taper outer tube 1 is greater than the internal diameter of described extension tube 11 upper ends, water droplet can drip on the outer wall of extension tube 11, derives by water guider 6 again.
4, taper outer tube 1 side is provided with cleaning door 3, conveniently taper airduct inside is cleared up.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Using scope of the present utility model not only is confined to tobacco cutting equipment, can be applicable to other industrial fields.
