Description

Refractory plate combined wind pipe

The utility model relates to a kind of refractory plate combined wind pipe, belongs to the device for ventilating and air conditioning technical field.

Airduct is widely used in the industry air conditioner facilities such as building, weaving, chemical industry, metallurgy, mine.In the ventilation duct job facilities, main at present galvanized sheet iron airduct, inorganic glass fibre reinforced plastic blast pipe, silica-calcium board airduct, Etta's plate airduct, the gypsum board airduct etc. of adopting.What application was more in the engineering is the galvanized sheet iron airduct, and this airduct is not corrosion-resistant, working life short, adopts the flange mode to connect, and inleakage is big, energy consumption is big, it is big to take space.The difficult problem that the galvanized sheet iron airduct is perishable though inorganic glass fibre reinforced plastic blast pipe has solved, working life is short, in engineering, obtained certain application, but it still adopts flange connection, inleakage is big, energy consumption is big, it is big to take space, and have big moisture absorption, in wet environment, have problems such as " moisture absorption ", " mildew ", " returning halogen ", water of condensation.Airducts such as silica-calcium board airduct, Etta's plate airduct, gypsum board airduct adopt some unique Placements to replace traditional flange connection, saved space, but these airducts exist that Placement complexity, body surface density are not high, insufficient strength, body are easily produced problems such as dirt.

The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of inleakage little, take that space is little, the simple board-like combined flue pipe of Placement.

The technical solution of the utility model is: the body 1 that the special way of pulling the fire-resistant combined flue pipe of formula is it by by tackiness agent (as silicon sealant, contact glue, common adhesive such as epoxy resin) bonding mutually two beam wind tube sheets and two perpendicular blast pipe board are formed, each anyhow blast pipe board can be that individual layer is fire-resistant and pull that (can be FRIM pulls, calcium silicate is pulled, gypsum is pulled, aluminum alloy various common refractories with certain intensity such as is pulled and is pulled) or (can be FRIM by inside and outside two-layer refractory layer, calcium silicate, gypsum, various refractory masses such as aluminum alloy) with certain intensity and the thermal insulation layer that do not fire that is sandwiched between them (can be asbestos, expanded perlite, various incombustible material layers such as glass wool) form, there is the opposite female male coupling of direction at body 1 two ends, and (end is protruding, one end is recessed, cooperatively interact, be convenient to interlocking mutually between the airduct section).In addition, also intrinsic (the useable glass glue of body length direction is prolonged in body 1 inside and outside four edges and corners, contact glue, various common adhesive such as epoxy resin are bonding or connect solid with self tapping screw) the fire-resistant inner protective corner bar 2 of dihedral and fire-resistant outer square staff 3 (be used to reinforce the body horizontal stroke, the edges and corners that perpendicular blast pipe board connects, can be by FRIM, calcium silicate, gypsum, various refractory materials such as aluminum alloy are made), prolonging short transverse in body 1 inner chamber also can be provided with stiffening rib 4 and (can be FRIM, calcium silicate, gypsum, aluminum alloys etc. are various have the individual layer of certain intensity fire-resistant pull or by inside and outside two-layer refractory layer and be sandwiched in do not fire the fire resistant air-duct plate that thermal insulation layer is formed between them), to strengthen the intensity of body.

Fig. 1 is the utility model schematic representation,

Fig. 2 is the utility model cross-sectional schematic,

Fig. 3 cuts open schematic representation for the utility model side.

Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated:

Example 1: as shown in Figure 1, 2, 3, this body 1 of pulling the fire-resistant composite air duct of formula is by forming by mutual bonding two beam wind tube sheets and the two perpendicular blast pipe board of common contact glue, each anyhow blast pipe board by inside and outside two-layer FRIM refractory layer and be sandwiched in asbestos between them and do not fire thermal insulation layer and form, there is the opposite female male coupling of direction at body 1 two ends, are convenient to interlocking mutually between the airduct section.In addition, body 1 inside and outside four edges and corners are prolonged the body length direction and are also added fire-resistant inner protective corner bar 2 of intrinsic dihedral FRIM and the fire-resistant outer square staff 3 of FRIM with common contact glue cementation and with self tapping screw, prolong the body short transverse in body 1 inner chamber and also be provided with FRIM stiffening rib 4, to strengthen the intensity of body 1.

Example 2: as shown in Figure 1, 2, 3, the body 1 of this composite air duct is by forming by mutual bonding two beam wind tube sheets and the two perpendicular blast pipe board of simple glass glue, respectively blast pipe board is that calcium carbonate is pulled anyhow, and there is the opposite female male coupling of direction at body 1 two ends, are convenient to interlocking mutually between the airduct section.In addition, body 1 inside and outside four edges and corners are prolonged that the body length direction also is adhesively fixed with simple glass and are added intrinsic aluminum alloy dihedral inner protective corner bar 2 and the outer square staff 3 of aluminum alloy with self tapping screw, prolong the body short transverse in body 1 inner chamber and also be provided with calcium carbonate and pull stiffening rib 4, to strengthen the intensity of body 1.

During use, will according to the airduct design size require this airduct of multistage made from the composite air duct plate by its female male coupling socket also with common gluing connecing, just can make air-line system easily.

The utility model is owing to adopt simple female male coupling linkage structure, solved the conventional flange Placement big deficiency that takes up room, and saves construction investment greatly.Female male coupling makes between airduct and closely connects, and inside and outside square staff makes airduct body secure seal more, significantly reduces thereby air-line system is leaked out.

The utlity model has following advantage:

1, making is simple, production cost is low, easy for installation, steady quality is reliable, is convenient to scale, standardized production:

2, take space few, connect good leak tightness, few, the less energy consumption of system's inleakage:

3, air-line system neat appearance:

4, fire-resistant anti-corrosion, long service life.
