Abstract
A kind of bar shaped screen cloth, comprises cross-brace bar, it is characterized in that on described cross-brace bar, seam uniformly and equidistantly has lengthways of rod, this lengthways of rod cross section is rhombus, lengthways of rod surface is provided with passivation layer, and described cross-brace sliver transvers section is square, and cross-brace bar surface is provided with blackout layer.The utility model structure is advanced, good filtration effect, and technique is simple, easy to operate, production cost is low.Its rhombus lengthways of rod and square cross-brace bar combine, and greatly can improve bearing capacity, and filtration resistance are little, not easily block, and especially arrange passivation layer, blackout layer at lengthways of rod and cross-brace bar, withstand corrosion, improves the endurance quality of screen cloth.The utility model also adopts double-layer filter structure, greatly can strengthen filter effect.The utility model improves the deficiencies in the prior art, has good economic benefit, has certain promotional value.
Description
Technical field
The utility model relates to a kind of petrochemical equipment, especially relates to a kind of bar shaped screen cloth and screen drum goods thereof.
Background technology
Strip-shaped screen is also Johnson's filter screen, and be the industrial screen cloth of one developed by Johnson Company, it is welded continuously by the rib of the grating longitudinally arranged and lateral arrangement, and its grating welds with each crosspoint of rib.But existing strip-type screen net filtration resistance is comparatively large, or easily blocks, especially not corrosion-resistant, has been not suitable with the high request of existing petrochemical industry.
Screen drum is the important process accessory in petrochemical equipment, the flat board of conventional production method Shi Xian production department wedge wire screen net, and then carries out blanking after launching by screen drum diameter dimension, veneer reeling machine rolls or compressing rear welding on forcing press.Because existing screen cloth exists many deficiencies, so that thoroughly affect service life and the result of use of screen drum, existing screen drum structure causes filtering surface less in addition, and filter effect reduces.
Utility model content
The utility model object is to provide a kind of bar shaped screen cloth and screen drum goods thereof, with improve screen cloth that prior art produces and screen drum filtration resistance is comparatively large, easily blocking, not corrosion-resistant, the technical problems such as screen drum unreasonable structure causes filtering surface less, filter effect reduction.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bar shaped screen cloth, comprise cross-brace bar, it is characterized in that on described cross-brace bar, seam uniformly and equidistantly has lengthways of rod, this lengthways of rod cross section is rhombus, lengthways of rod surface is provided with passivation layer, and described cross-brace sliver transvers section is square, and cross-brace bar surface is provided with blackout layer.
The screen drum that a kind of bar shaped screen cloth is made, comprise annular support bar, it is characterized in that on described annular support bar, axially seam uniformly and equidistantly has lengthways of rod, this lengthways of rod cross section is rhombus, lengthways of rod surface is provided with passivation layer, described annular support bar cross section is square, and annular support bar surface is provided with blackout layer.
As preferably, described screen drum has top cover and bottom, described bottom comprises interior annular support bar, middle annular brace bar, Outer annular support bar and radiation rib, in described, be provided with annular plank between middle annular brace bar, on middle annular brace bar, Outer annular support bar, radial direction is welded with radiation rib uniformly and equidistantly.
As preferably, be also provided with interior screen drum in described screen drum, interior screen drum top is connected with middle annular brace bar.
The utility model structure is advanced, good filtration effect, and technique is simple, easy to operate, production cost is low.Its rhombus lengthways of rod and square cross-brace bar combine, and greatly can improve bearing capacity, and filtration resistance are little, not easily block, and especially arrange passivation layer, blackout layer at lengthways of rod and cross-brace bar, withstand corrosion, improves the endurance quality of screen cloth.The utility model also adopts double-layer filter structure, greatly can strengthen filter effect.The utility model improves the deficiencies in the prior art, has good economic benefit, has certain promotional value.

Fig. 5 is the generalized section of screen drum shown in Fig. 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
From Fig. 1,2,3, this bar shaped screen cloth comprises cross-brace bar 1 and lengthways of rod 2, on cross-brace bar 1, seam uniformly and equidistantly has lengthways of rod 2, lengthways of rod 2 cross section is rhombus, lengthways of rod 2 surface is provided with passivation layer 3, passivation layer 3 is that oxygen molecule structure passivating film, rete that metal surface is formed are fine and close, stable performance, and has self-healing effect in atmosphere simultaneously, and the passivating film that passivation is formed is more stable, have more corrosion resistance.
Cross-brace bar 1 cross section is square, and cross-brace bar 1 surface is provided with blackout layer 5.Blackout layer 5 is a kind of chemical surface treatment, and its Main Function is the oxide-film forming one deck densification at surface of the work, prevents workpiece corrosion from getting rusty, and improves the wearability of workpiece.Cross-brace bar 1 on screen cloth and lengthways of rod 2, all through surface treatment, improve non-oxidizability, the corrosion resistance of screen cloth; Lengthways of rod 2 cross section is rhombus, reduces filtering surface, strengthens filter effect.
Adopt the screen drum that above bar shaped screen cloth is made, comprise annular support bar, top cover 6, bottom 7, annular cross-brace bar 21 and lengthways of rod 2, on annular support bar, axially seam uniformly and equidistantly has lengthways of rod 2, lengthways of rod 2 cross section is rhombus, lengthways of rod 2 surface is provided with passivation layer 3, horizontal 21 cross sections of annular support bar are square, and annular support bar 21 surface is provided with blackout layer 5.
Bearing screen drum top is provided with top cover 6 and bottom 7, bottom 7 comprises interior annular support bar 8, middle annular brace bar 9, Outer annular support bar 10 and radiation rib 11, in, be provided with annular plank 13 between middle annular brace bar 8,9, on middle annular brace bar 9, Outer annular support bar 10, radial direction is welded with radiation rib 11 uniformly and equidistantly; Bottom 7 is formed one filtered bottom by interior annular support bar 8, middle annular brace bar 9, Outer annular support bar 10, radiation rib 11, avoids the blank space of screen drum filtering surface.Also be provided with interior screen drum in screen drum, interior screen drum top is flexibly connected with middle annular brace bar 9 movable connection methods such as () bolt is connected, clampings, and whole screen drum forms double filter layers, can form double filtration effect, make filter effect better.
Finally it should be pointed out that above detailed description of the invention is only the more representational example of the utility model.Obviously, the invention is not restricted to above-mentioned detailed description of the invention, many distortion can also be had.Every above detailed description of the invention is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
