Description
Technical Field
The utility model relates to an anticorrosion blast pipe.
Background
Because the kitchen oil smoke greasy dirt is great, use the back blast pipe for a long time again and must wash, otherwise can seriously influence smoke exhaust effect, the greasy dirt accumulation is too much also can cause the potential safety hazard, present lampblack absorber blast pipe adopts integrated into one piece formula pipeline mostly, and this kind of blast pipe washs very inconveniently, has the washing dead angle. The existing exhaust pipe is poor in anti-corrosion effect, and is easy to corrode after being used for a long time, so that the exhaust pipe is damaged, and the service life of the exhaust pipe is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides an effective corrosion prevention to the not enough of prior art, the utility model provides a clear up convenient anticorrosion blast pipe.
In order to achieve the above object, the utility model provides a following technical scheme:
an anti-corrosion exhaust pipe comprises two arc pipes which are symmetrically arranged, the two arc pipes are combined into a circular flue, the inner wall of arc pipe sets gradually three layer construction from inside to outside, be high temperature resistant layer respectively, the inoxidizing coating, the anticorrosive coating, equal fixedly connected with picture peg on two arc pipes, the slot has all been seted up on two arc pipes, adjacent picture peg and slot are pegged graft each other, the back of bottom arc pipe is provided with the first arc snap ring that the equidistance was arranged, the threaded rod that two symmetries of top fixedly connected with of first arc snap ring set up, the top of top arc pipe is provided with the second arc snap ring that the equidistance was arranged, the through-hole that two symmetries set up is seted up to the bottom of second arc snap ring, the top of two threaded rods is run through respectively and sliding connection is to the top of two through-holes, the equal threaded connection in the outside of two threaded rods has the nut, the bottom of two nuts all contacts with the top of second arc snap ring.
Preferably, the high temperature resistant layer is glass fiber.
Preferably, the protective layer is polytetrafluoroethylene.
Preferably, the anticorrosive layer is novolac epoxy.
Compared with the prior art, the utility model discloses possess following beneficial effect:
the utility model discloses inner wall at the arc pipe sets up that outside protective layer is rotten, inside inoxidizing coating and inside high temperature resistant layer, protects the body, and the body is corroded to the life of blast pipe has been guaranteed. In addition when the blast pipe need clear up, at first twist and loosen the nut, then with first arc snap ring and the separation of second arc snap ring, then with two arc pipe separations at top, then rinse the inside through the sanitizer and erode, the blast pipe has just so possessed the clearance of being convenient for, and the clearance does not have the dead angle, clearance labour saving and time saving's advantage.
Drawings
Fig. 1 is a schematic structural diagram of an anti-corrosion exhaust pipe of the present invention.
Fig. 2 is a schematic view of the layered structure of the arced tube of fig. 1.
In the figure: 1. an arc tube; 1.1, a high temperature resistant layer; 1.2, a protective layer; 1.3, an anticorrosive layer; 2. inserting plates; 3. a slot; 4. a first arcuate snap ring; 5. a threaded rod; 6. a second arc-shaped snap ring; 7. a through hole; 8. and a nut.
Detailed Description
Referring to fig. 1 and 2, the utility model relates to an anticorrosion blast pipe, arc 1 including two symmetry settings, the inner wall of arc 1 sets gradually high temperature resistant layer 1.1, inoxidizing coating 1.2, anticorrosive coating 1.3 from inside to outside, and wherein high temperature resistant layer 1.1 is glass fiber, and inoxidizing coating 1.2 is polytetrafluoroethylene, and anticorrosive coating 1.3 is phenol epoxy, avoids arc 1 to take place to corrode the oxidation.
Equal fixedly connected with picture peg 2 on two arc pipes 1, slot 3 has all been seted up on two arc pipes 1, adjacent picture peg 2 and slot 3 peg graft each other, two combination of arc pipes 1 are circular flue, the back of bottom arc pipe 1 is provided with first arc snap ring 4 that the equidistance was arranged, the threaded rod 5 that two symmetries of top fixedly connected with of first arc snap ring 4 set up, the top of top arc pipe 1 is provided with the second arc snap ring 6 that the equidistance was arranged, the through-hole 7 that two symmetries set up is seted up to the bottom of second arc snap ring 6, the top of two threaded rod 5 runs through respectively and sliding connection to the top of two through-holes 7, the equal threaded connection in the outside of two threaded rod 5 has nut 8, the bottom of two nuts 8 all contacts with the top of second arc snap ring 6.
When the device is used, firstly, two arc-shaped pipes 1 are spliced and combined into a circular flue through two inserting plates 2 and two inserting grooves 3, then the circular flue is aligned through a first arc-shaped clamping ring 4 and a second arc-shaped clamping ring 6, two threaded rods 5 penetrate through the inside of two through holes 7, then the exhaust pipe is fixedly formed by screwing a nut 8, when the exhaust pipe needs to be cleaned, the nut 8 is firstly unscrewed, then the first arc-shaped clamping ring 4 and the second arc-shaped clamping ring 6 are separated, then the two arc-shaped pipes 1 at the top are separated, and then the inside is cleaned and washed by a cleaning agent, so that the device has the advantages of convenience in cleaning, no dead angle in cleaning, time and labor saving, the problems that the oil stain of kitchen is large, the outer flue needs to be cleaned after long-time use, otherwise, the smoke exhaust effect can be seriously influenced, the safety hidden danger can be caused by excessive accumulated oil stains are solved, the outer flue of the existing range hood adopts an integrally formed pipeline, the pipeline cleaning is very inconvenient, dead angles exist in the cleaning, and time and labor are wasted.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
