Abstract

The utility model discloses a novel fireproof safe flue gas exhaust channel which comprises a flue pipe, and is characterized in that the flue pipe comprises a main pipe body layer; the inner wall of the main pipe body layer is provided with a metal mesh layer; a gridding cloth layer is arranged at the inner side of the metal mesh layer; the peripheral wall of a communicating hole of the flue pipe is connected with a guide side. The novel fireproof safe flue gas exhaust channel is not provided with a spliced assembly, is good in sealing performance and has a fireproof function; the novel fireproof safe flue gas exhaust channel is reasonable in structure, light and thin, and saves the material; the mechanical strength of the novel fireproof safe flue gas exhaust channel is improved, and the service life of the novel fireproof safe flue gas exhaust channel is prolonged.

Description

The safe exhaust gas flue of a kind of Novel fireproof

Technical field

The utility model relates to a kind of fume extractor, relates in particular to the safe exhaust gas flue of a kind of Novel fireproof.

Background technology

Its basic structure of fume emission passage that generally includes house etc. mainly consists of cement mortar Component composition, the structure of this smoke vent is relatively complicated, production process is many, making requires high, because needs are used installed part, be connected, safe and reliable for guaranteeing, flue mainboard body thickness is large, make the raw material of needs many, also make manufacturing cost increase.And owing to adopting splicing need to carry out encapsulation process between each assembly, when sealing is improper or use with the passing of time, can there is gas leak phenomenon, this may initiation fire etc. security incident.And the monolithic smoke vent that the problem existing for this class fume extractor is released is due to reasons such as formations, the weight of its intensity and self etc. cannot be coordinated, or thickness does greatlyr, or firmness is inadequate, bring very big inconvenience to installation and use, to such an extent as to increase cost of production and use cost.

Utility model content

The purpose of this utility model is the deficiency existing for prior art, provide a kind of Novel fireproof safe exhaust gas flue, the safe exhaust gas flue manufacturing process of this Novel fireproof is simple, simple in structure, lightweight, firm and durable, easy for installation, safe and reliable, good seal performance, has fire-proof function, and cost of production is low.

The technical solution of the utility model comprises flue pipe, and described flue pipe comprises main pipe's layer, and the inwall of described main pipe's layer is provided with an oven wire mesh blanket, and described oven wire mesh blanket inner side is provided with a grid layer of cloth, and its sidewall of described flue pipe is provided with corresponding UNICOM mouth.

Described main pipe's layer is that a main pipe who consists of high strength cement and constructional materials processing leftover is outer.

Described constructional materials processing leftover comprises coal ash and/or wood chip.

Described oven wire mesh blanket is stainless steel metal silk screen layer, and described grid layer of cloth is fiberglass gridding cloth layer.

It is a monolithic that described flue pipe is built.

On described flue pipe inside wall, be and be longitudinally provided with at least two reinforcing ribs.

On UNICOM's mouth perisporium of described flue pipe, be connected with a leading edge.

The safe exhaust gas flue of this Novel fireproof does not does not only splice and combine part, and good seal performance, has fire-proof function, due to the reasonability of its structure, accomplish light, thin, save material in, increased mechanical strength and application life.

Accompanying drawing explanation

Fig. 1 is the utility model one example structure schematic diagram; Fig. 2 is Fig. 1 cross-sectional structures now schematic diagram; Fig. 3 is another example structure schematic diagram of the utility model.

The specific embodiment

Now by embodiment, also the utility model is described in further detail by reference to the accompanying drawings.

As illustrated in fig. 1 and 2, in the present embodiment, flue pipe 4 comprises the main pipe's skin 1 consisting of high strength cement, wood chip and coal ash etc. that is positioned at outside, be located at a stainless steel wire stratum reticulare 2 of the internal perisporium of main pipe's skin 1, be located at a fiberglass gridding cloth layer 3 of the internal perisporium of stainless steel wire stratum reticulare 2; Disposable by machine automatization, to build structure in aggregates by stainless steel cloth, fiberglass gridding cloth and high strength cement, wood chip and coal ash etc. for flue pipe 4, offers UNICOM's mouth 5 on the sidewall of flue pipe 4; Flue pipe 4 is circular, and it is highly 2800mm, and diameter is that 200-250mm ，Qi UNICOM mouth 5 is opened on the sidewall of locating apart from the upper port 500mm left and right of flue pipe 4.

Another embodiment of the utility model as shown in Figure 3, in the present embodiment, on the relative both sides inwall of flue pipe 4, be respectively equipped with a reinforcing rib 7 that is axial direction, around UNICOM's mouth 5 perisporiums, be provided with a leading edge 6 that protrudes from the outside wall surface of flue pipe 4, with guiding, connect corresponding interface channel, play the effect of strengthening bonding strength and sealing; UNICOM's mouth 5 and corresponding leading edge 6 thereof can be reserved formation when flue pipe monobloc cast, also can after flue pipe is built moulding, excavate formation.All the other structures can with above-described embodiment roughly the same.

In an embodiment more of the present utility model, the sidewall Bu She UNICOM mouth of flue pipe, fiberglass gridding cloth layer is positioned at the pars intramuralis of building of monolithic casting tube 1.All the other structures can with above-mentioned arbitrary embodiment roughly the same.

Other modified products of technical scheme based on the safe exhaust gas flue of this Novel fireproof all belong to protection domain of the present utility model, and above-described embodiment is not the exhaustive of the specific embodiment of the present utility model.
