Abstract

The utility model relates to a laser cut narrow-slit sieve plate, which is characterized in that the sieve plate comprises a steel plate, a plurality of slits and a plurality of supporting strips which are all cut via laser, the strip-type slits which are cut via laser and the supporting strips which are perpendicular to the slits are all arranged on the steel plate, the slits are spaced by the supporting strips, and the slits along directions of the supporting strips are parallel mutually. The narrow-slit sieve plate is simple and reasonable in structure, not easy to be blocked, fine in filter effect, long in service life, low in production cost and suitable to be popularized and applied.

Description

Laser cutting narrow slit sieve plate

One, technical field:

The utility model relates generally to a kind of sieve plate that filters usefulness, particularly relates to a kind of narrow slit sieve plate that adopts the laser cutting moulding, is applicable to that petrochemical industry, sewage disposal etc. are multi-field.

Two, background technology:

It mainly is porous plate and braid fabric that metal filter screen is used many on traditional industry, porous plate is that a lot of the apertures that filter usefulness are set on metallic plate, but after using a period of time, big filter residue is easy to influence filter effect with regard to making the filtering holes obstruction; Braid fabric adopts circular finer wire braiding, laterally with vertical interlaced overlap joint surface irregularity, the filter opening outside that adjacent wires forms is big, the center is little, this filter opening structure is because solid particle (catalyst, molecular sieve and various filtrates etc.) big with the silk screen contact area, particle stops up easily, difficult drop-off, backwash also is difficult for rinsing out, and filter screen can not get effective cleaning, and the general out-of-flatness of mesh grid, there are corrugated wrinkle, this wrinkle in use very easily cause the superimposed of wrinkle portion, cause filter screen meeting warpage behind this place's pressurized, even fracture damage, service life is short, cause expensive medium loss, even device can't be operated, maintenance is also relatively more difficult;

Though also occurred the screen cloth of some gap-shapeds in the market, it is general that all to be the mode that adopts electric resistance welding be welded on the wire of V-type on the support bar, but the welding manner energy input of this electric resistance welding is very big, the expense of production early investment just reaches more than 10,000,000, production cost is very big, how to produce a kind of good filtration effect, is difficult for obstruction, long service life and the low filtration sieve plate of production cost just become problem demanding prompt solution.

Three, utility model content:

1, goal of the invention:

The problem that aspects such as the utility model provides a kind of laser cutting narrow slit sieve plate, and its purpose is to solve existing in the market metal filter screen poor filtration effect, obstruction easily, service life is short, production cost is big exist.

2, technical scheme:

The utility model is achieved through the following technical solutions:

A kind of laser cutting narrow slit sieve plate, it is characterized in that: this narrow slit sieve plate comprises steel plate, slit and the support bar that adopts laser cutting, steel plate is provided with the slit of a plurality of employing laser cutting, the slit is bar shaped, also be provided with a plurality of on the steel plate and the perpendicular support bar in slit, separate in supported of slit, is parallel to each other between the slit of support bar direction.

The thickness of the steel plate of described employing laser cutting is 8～20mm, and the width in the slit of described employing laser cutting is 0.2～1mm.

The thickness of the steel plate of described employing laser cutting is 10mm, and the width in the slit of described employing laser cutting is 0.3mm.

Described steel plate can be cut into rectangle, square, circle, ellipse or other polygonal shape.

3, advantage and effect:

The utility model provides a kind of laser cutting narrow slit sieve plate, compares with at present common metal filter screen, owing to adopted the technology of laser cutting, this sieve plate has the following advantages:

Plate thickness is thin, the slit is narrow;

Valid circulation area is big, is difficult for stopping up;

The intensity height, durability is strong;

Maintenance rate is low, reduces shutdown loss;

Resistance to wear long service life.

Four, description of drawings:

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is a perspective view of the present utility model.

Description of reference numerals:

In Fig. 1-Fig. 2: 1-steel plate, 2-slit, 3-support bar.

Five, the specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

The utility model provides a kind of laser cutting narrow slit sieve plate, it is characterized in that: as shown in Fig. 1-Fig. 2, this narrow slit sieve plate comprises steel plate 1 and slit 2 and the support bar 3 that adopts laser cutting, on steel plate 1, be provided with the slit 2 of a plurality of employing laser cutting, slit 2 is uniform bar shaped, also be provided with the perpendicular support bar 3 in a plurality of and slit 2 on the steel plate 1, separate in 2 supported 3 in slit, is parallel to each other between the slit 2 of support bar 3 directions; The non-difference of mode energy consumption of the resistance welded of Cai Yonging was big in the past, and production cost is very high, and adopted laser little more a lot of than the energy consumption of resistance welded mode, so production cost of the present utility model is low-down, was fit to large-scale commercial Application.

Described slit 2 adopts laser cutting to form, cutting can make the slit 2 of sieve plate reach the very little width of actual needs like this, this adopts the resistance welded mode to realize, and valid circulation area is big, reached and prevented the purpose stopped up, thereby prolonged the service life of sieve plate, and filter effect is better.

The thickness of the steel plate 1 of described employing laser cutting can reach 8～20mm, the width in the slit 2 of described employing laser cutting can reach 0.2～1mm, just because of employing laser, could under the much lower situation of cost, cut out thickness steel plate 1 and width also than the electric resistance welding narrow slit 2 littler than electric resistance welding.

When the thickness of the steel plate 1 of described employing laser cutting is 10mm, when the width in the slit 2 of described employing laser cutting is 0.3mm, filter effect the best.

Described steel plate 1 can be according to actual needs different with application, adopt laser cutting to become rectangle, square, circle, ellipse, triangle or other polygonal shape.

When the utility model laser cutting narrow slit sieve plate uses, can make this sieve plate directly among the embedding equipment, be convenient to applied range is installed.For example in petrochemical industry, be mainly used in sector drum, central tube, inlet basket and the outlet basket of radial reactor in the catalytic reforming unit; The support grid of the inlet dispenser of general reactor, sediment incrustation basket, beds, exit collector etc.; Also can be used for filter tube, centrifuge filtration hoop and vibratory sieve etc., and can make different shapes according to the difference of application.

This laser cutting narrow slit of the utility model sieve-plate structure is rationally simple, good filtration effect, be difficult for resulting in blockage, long service life, production cost is low, is suitable for industrial large-scale promotion application, and have wide range of applications, can be used for petrochemical industry, sewage disposal, multiple fields such as mineral, papermaking and food processing.
