Abstract
The utility model discloses a water descaling bag filter on a profile steel tandem rolling line. The filter consists of a cylinder body, a cylinder cover and a support, wherein the cylinder body and the cylinder cover are connected by a screw with a rubber seal ring; a water inlet flange extends into a bag filter net in the cylinder body through the cylinder cover; a pressure gauge is mounted on the cylinder cover; and a water outlet flange is arranged at the lower part of the cylinder body. By adopting the filter, descaling polluted water is filtered and then recycled, and at the same time harm to the environment due to direct discharge of the polluted water is avoided, the production cost is saved, and the economic benefit of enterprises is improved.
Description
Technical field
The utility model belongs to metallurgical steel rolling process field, is specifically related to a kind of continuous section rolling line water de-scaling bag filter, so that continuous section rolling line water de-scaling water can recycle the energy of not only having protected environment but also having saved.
Background technology
At present, continuous section rolling line water descaling device adopts the High-Pressure Water douche, this method is that low-pressure water is delivered to nozzle by pressure piping after the high-pressure pump pressurization, the water that nozzle forces down flow velocity with height changes into the jet of low pressure high flow rate, forward or the tangential hot rolling steel billet for the treatment of de-scaling that hits, when steel billet ran into the jet of high flow rate, explosion occured because of instantaneous cold contraction in iron oxide on surface of billet steel skin (being commonly called as firecoat), under the impact of water jet, come off from billet surface rapidly, realize de-scaling.Because nozzle will be realized the high pressure low speed water to the conversion of low-voltage high speed water, this can not contain and surpass the impurity that limits size just so that nozzle is very high to the water requirement, otherwise, the as easy as rolling off a log obstruction of nozzle.Just can not continue to use so be mixed with the water of firecoat, and directly discharging has also been wasted the energy not only to environment.
Summary of the invention
In view of the situation of above-mentioned technology, the utility model provides a kind of continuous section rolling line water de-scaling bag filter, and it has impurity screening, so that the water after filtering can satisfy the requirement of nozzle fully, reaches the recycling purpose of water resource.
For achieving the above object, the utility model continuous section rolling line water de-scaling bag filter is like this design: continuous section rolling line de-scaling water-bag-type filter is comprised of cylindrical shell, cover and support, wherein, is tightly connected by screw between cylindrical shell and the cover; Water-in flange stretches into bag type filtering net in the cylindrical shell by cover, and Pressure gauge is installed on the cover, is water-output flange in the cylindrical shell bottom.It is online that de-scaling sewage is fallen bag type filtering by water-in flange through cover, and the impurity in the de-scaling water is attached to, and current then flow into water circulation system by micron order bag type filtering net through water-output flange.
The utility model continuous section rolling line water de-scaling bag filter recycles de-scaling sewage after filtering, the direct emission hazard environment of the sewage of avoiding again simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, water-in flange, 2, Pressure gauge, 3, cover, 4, with the trip bolt of sealing ring, 5, micron order bag type filtering net, 6, cylindrical shell, 7, water-output flange, 8, support.
The specific embodiment
As seen from Figure 1, the utility model is comprised of cylindrical shell (6), cover (3) and support, wherein, is connected by the screw (4) with rubber seal between cylindrical shell (6) and the cover (3); Water-in flange (1) stretches into the interior micron order bag type filtering net (5) of cylindrical shell (6) by cover (3), and Pressure gauge (2) is installed on the cover, is water-output flange (7) in cylindrical shell (6) bottom.Sewage is fallen on the micron order bag type filtering net (5) through cover (3) by water-in flange (1), and diameter is attached to greater than 1 micron impurity, and current then flow into water circulation system by micron order bag type filtering net (5) through water-output flange (7).The pressure of the direct main detection system that links to each other with cover (3) of Pressure gauge (2); if detecting the pressure superelevation explanation micron order bag type filtering net (5) of system blocks; need to clean or change; need trip bolt is unclamped when cleaning or change, whole process manually-operated is simple, does not need to shut down; processing time is short; the usual micron order cloth bag that only needs to change in the bag filter, cloth bag can also reuse by cleaning, and is easy to maintenance.It is little to have suffered system's floor space, safe and reliable aborning, and solves to a large extent the recycling of sewage, has saved production cost, has improved Business Economic Benefit.
Claims (3)
1. continuous section rolling line water de-scaling bag filter, described water de-scaling bag filter is comprised of cylindrical shell, cover and support, it is characterized in that being connected by screw between cylindrical shell and the cover; Water-in flange stretches into bag type filtering net in the cylindrical shell by cover, and Pressure gauge is installed on the cover, is water-output flange in the cylindrical shell bottom.
2. continuous section rolling line water de-scaling bag filter according to claim 1 is characterized in that being connected by the screw with rubber seal between cylindrical shell and the cover.
