Abstract
The utility model discloses a high-temperature folding aramid fiber filter barrel. A high-temperature aramid fiber filter material is in a creased form after being folded multiply and is fixed at the outer side of a cylindrical support frame; and an external fixing band is fixed at the outer side of aramid fibers. The high-temperature folding aramid fiber filter barrel has the advantages that the filter material with a creased form is adopted, so that the area of a filter unit is enlarged at a same filter wind speed, and the filtering efficiency of a dust collector is improved.
Description
Technical field
The utility model relates to the aramid fiber high temperature filtration tube of the discounting that a kind of filter drum type precipitator that is used for liquid-solid separation and gas-solid separation technology field uses.
Background technology
Existing deduster great majority adopt house-bag duster for high temperature, as industrial circles such as cement, iron and steel, electric power, food, metallurgy, chemical industry, but sometimes be subjected to the place restriction, make the filter area increase be restricted, thereby have to increase load of dust remove, make deduster to capture difficulty, the filtration velocity height of fine dust like this, influenced the service life of deduster greatly.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of high temperature resistant, and the aramid fiber high temperature filtration tube than the discounting of long life is arranged.
In order to solve above technical problem, the utility model provides a kind of aramid fiber high temperature filtration tube of discounting, the multiple folding formation pleat formula fixed in shape of aramid fiber high-temperature-resistant filtering material is in the outside of a cylindrical shape bracing frame, be fixed with the external stability band in the outside of aramid fiber, by folding of aramid fiber high-temperature-resistant filtering material realized increasing filter area.
The material of described external stability band is the aramid fiber high-temperature-resistant filtering material.
The aramid fiber high-temperature-resistant filtering material is a single layer structure, handles by shredding, combing, lapping, pinprick reinforcement, sclerosis impregnation to aramid fiber short fibre, and implementation specification is at 200-350g/m
2Between the high temperature resistant Nomex stock of aramid fiber, adopt discounting machine to give a discount to this stock then according to the interval of 1～5cm, make cartridge filter again.
Superior effect of the present utility model is: can be in the time can't increasing deduster quantity and increase filter area, be effective by the filter area that increases filtrate, owing to adopt pleat formula shape filtrate, under same filtration velocity, the area of filter element increases, increase the filter efficiency of deduster, solved the restriction in deduster place, solved the difficult problem of fume emission for the client.

3-external stability band.
The specific embodiment
Below in conjunction with specifically executing example, further set forth the utility model.
As shown in Figure 1-Figure 3, the utility model provides a kind of aramid fiber high temperature filtration tube of discounting, aramid fiber high-temperature-resistant filtering material 1 multiple folding formation pleat formula fixed in shape is in the outside of a cylindrical shape bracing frame 2, be fixed with external stability band 3 in the outside of aramid fiber, by folding of aramid fiber high-temperature-resistant filtering material 1 realized increasing filter area.
The material of described external stability band 3 is the aramid fiber high-temperature-resistant filtering material.
The utility model mainly is to adopt resistant to elevated temperatures aramid fiber to form Nomex through shredding, combing, lapping, acupuncture, sclerosis impregnation, typing.The product specification that this Nomex forms is at 200-350g/m
2Between, the mass area ratio of product is lighter, has certain rigidity and deflection, easily gives a discount, and has broken through the problem that Nomex can only be made thick type dedusting filter bag and can not give a discount; Aramid fiber is a high-temperature fibre simultaneously, and long-term serviceability temperature can reach 205 ℃, for dedusting can not be in order to the above problem of 150 degree with filter cylinder.
