Description
Technical Field
The utility model relates to the technical field of industrial and building smoke prevention and exhaust composite air pipes, in particular to a smoke prevention and exhaust composite air pipe.
Background
The tuber pipe is a municipal infrastructure for making the air circulation, reduce harmful gas concentration. The plate, section bar and other main finished product materials used for manufacturing and installing the air duct are in accordance with the regulations of the national current standard of design and related products, and are proved by factory inspection to be qualified, and the materials are checked and accepted according to the national current related standard when entering the field. The tuber pipe is mainly used in industry and building engineering, and application field mainly relates to: electronic industry dustless factory building clean system, medicine food aseptic workshop clean system, the central air conditioning system of hotel, market hospital, mill and office building, exhaust pipe such as dust removal, exhaust gas, oil absorption for industrial pollution control, supply-air pipe for industrial environment or post are comfortable, gas is taken out and put out with gas drainage system, coal mine environmental control is with sending back wind system etc..
Under the support of relevant policies of the government of China, the consumption of the air ducts shows a rapid growth trend. Compared with developed areas of air duct industry, the air duct industry system in China is still imperfect and has a large gap. The development of the air duct industry in China is late, the process is backward, and adverse factors such as environmental pollution are brought. Therefore, two steps of 'quantitative change' and 'qualitative change' must be completed to meet the increasing social requirements of the air duct industry.
The internal reinforcement of tuber pipe is the problem that the tuber pipe manufacturing process is necessary to consider, and tuber pipe rectangular pipe is thinner for the water pipe, for reaching the technology demand, in present work progress, the internal reinforcement method of adoption is mainly to set up the support column in the tuber pipe to the intensity of reinforcing tuber pipe, but the tuber pipe is the rectangle structure usually, when the preparation tuber pipe, the welding support column is inconvenient, and still need carry out anti-rust treatment to weld seam department after the welding is accomplished, and is very inconvenient.
The existing smoke prevention and exhaust air duct applied to industry and buildings is generally an iron sheet air duct which is additionally provided with a very thick rock wool heat preservation layer and then is covered with an iron sheet layer, the method has the advantages that the air duct has larger self weight, more troublesome construction and unsatisfactory heat preservation performance, a field required by construction is necessary to be spacious, and the environmental pollution is easily caused; this is in contrast to the fourteen-five planning goals of our country: the low carbon, environmental protection, green and energy saving are not consistent.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides an anti-smoke and exhaust composite air pipe.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prevent compound tuber pipe of discharging fume, includes the rectangular pipe, the rectangular pipe include the interior surface course with the surface course outward, the interior surface course with be equipped with the intermediate level between the surface course outward, the intermediate level is inorganic fiber insulating layer.
Preferably, the inner surface layer and the outer surface layer are both galvanized steel sheets.
Preferably, a reinforcing member is arranged in the rectangular pipe.
Preferably, the reinforcement includes the nut, be equipped with the through-hole on the rectangular pipe, nut fixed connection be in through-hole department nut internal thread connects the screw rod, and the screw rod is followed penetrate to the rectangular pipe in the through-hole, screw rod one end with the inner wall of rectangular pipe contacts.
Preferably, the top of the screw is fixedly connected with the pressing plate.
Preferably, a sealing ring is arranged between the pressure plate and the nut.
Preferably, the sealing ring is a teflon gasket.

Drawings
FIG. 1 is a schematic view of the basic structure of a smoke prevention and exhaust composite air duct provided by the present invention;
fig. 2 is an enlarged view of a portion a of fig. 1.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Example 1
As shown in fig. 1 and fig. 2, the smoke prevention and exhaust composite air duct provided by this embodiment includes a rectangular duct 1, where the rectangular duct 1 includes an inner surface layer 12 and an outer surface layer 11, and both the inner surface layer 12 and the outer surface layer 11 are galvanized steel sheets. An intermediate layer 13 is arranged between the inner surface layer 12 and the outer surface layer 11, and the intermediate layer 13 is an inorganic fiber heat insulation layer. The inorganic fiber heat-insulating material is coated between the inner surface layer 12 and the outer surface layer 11, which can not stimulate the skin of constructors and inhale respiratory system, is beneficial to protecting the health of field personnel,
the inside of the rectangular pipe 1 is provided with a reinforcing piece. The reinforcement includes nut 2, be equipped with the through-hole on the rectangular pipe 1, 2 fixed connection of nut are in through-hole department, through-hole and the coaxial setting of screw hole of nut 2 female connection screw rod 3 of nut, screw rod 3 follow penetrate to rectangular pipe 1 in the through-hole, 3 one end of screw rod with the inner wall of rectangular pipe 1 contacts. The top of the screw rod 3 is fixedly connected with a pressing plate 4. A sealing ring 21 is arranged between the pressure plate 4 and the nut 2. The seal ring 21 is a teflon washer. The through-hole can be sealed to some extent by the sealing ring 21. The top of the pressing plate 4 is fixedly connected with a hexagonal plate 41. The screw 3 is conveniently turned by a wrench by means of the hexagonal plate 41. The screw rod 3 later stage construction in-process assembled installation reduces the production degree of difficulty of preventing compound tuber pipe of discharging fume. The nuts 2 are welded on the outer side of the outer surface layer 11, so that compared with the prior art in which the nuts are directly welded on the inner side for reinforcement, the method is much more convenient.
