Abstract
The utility model relates to an air discharge channel, in particular to a disposable molding air discharge channel, which is in a shape of a rectangular. Round through holes are arranged inside the air discharge channel, and the air discharge channel is integrally molded at one time. Compared with traditional air discharge channels, the air discharge channel is one-time molded through a mold, thereby being convenient to process, suitable for mass production in factories and capable of reducing production cost. During installation, contact area between single bodies is larger, so that integral bearing capability of the air discharge channel can be increased. The novel air discharge channel meets a current national criterion, and the round air discharge channel further meets the requirement of shapes of fluid dynamics, reduces resistance of air flow, increases flowing performance of the fluid, further facilitates air ventilation and air discharge and has high practicability.
Description
Technical field
The utility model relates to a kind of extract duct, is specifically related to the disposal molding exhaust duct.
Background technology
The cement flue of Cai Yonging is through the following problem of ubiquity in the market: the cement flue belongs to the artificial manual operations of adopting, and in uneven thickness, material is by standard proportioning, cracking very easily.Cement flue quality is heavy, and transportation is easily split, easily broken and installation inconvenience.The cement flue stretching resistance that installs is little, drawing crack easily.When the breaking out of fire of kitchen, the cement flue comes off easily, can cause heavy damage to the kitchen of having fitted up, and life property safety of people and public interest are caused very big hidden danger.A kind of combined type kitchen guarding exhaust duct is arranged on the market, adopt magnesite material to make, reduced the weight of flue segmentation, but because complex manufacturing technology, splicing place is easy to generate the crack, and member comes off easily, the quality instability, sealing is poor, anti-aging, corrosion resistance is poor.The easy anti-halogen of glass magnesium plate is frost instead, and the adhesive property that whitewashes sticking face brick is poor, and durability can't guarantee, the later stage is used exist serious potential safety hazard.
Summary of the invention
The purpose of this utility model is at top described problem, and a kind of easy, steadiness and higher exhaust uptake of safety processed is provided.
The utility model is achieved by the following technical programs.
Disposal molding exhaust duct, described exhaust duct are rectangular-shaped, and exhaust duct inside is provided with manhole, and described exhaust duct is the overall time moulding.
Described exhaust duct adopts common material or light material compacting to form.Use low alkali cement or ordinary Portland cement, add light fire-proof material (as glass bead, haydite, facing sand etc.), a small amount of specialist additive, reinforcements such as middle adding gauze wire cloth or wire drawing reinforcing bar, low alkali grid cloth, reinforcing mat.
Described exhaust duct height h is 1 ~ 4 meter, and the long a in cross section is 200mm ~ 800mm, and the wide b in cross section is 200mm ~ 800mm.
The cross sectional shape of described manhole is for positive circular, oval or be made of other irregular sealing camber lines.
The beneficial effects of the utility model are: compare with traditional exhaust duct, the utility model adopts the mould disposal molding, process easyly, and suitable factory mass production can reduce production costs.During installation, the contact surface between each monomer is bigger, has increased the supporting capacity of exhaust duct integral body.This novel exhaust road meets existing national standard, and the circular row air flue more meets fluid dynamic shape, reduces the resistance of gas communication, helps to increase the flowability of fluid, more helps ventilating and exhaust, and practicality is stronger.
