Description

Seamless welding precision filter screen for water treatment

Technical Field

The utility model relates to a filtration equipment, especially a seamless welding precision filter screen for water treatment.

Background

At present, in municipal sewage treatment, water resource recovery, cyclic utilization and industrial wastewater treatment, the used filter screens comprise single-layer screen meshes, sintered screen meshes, punching plate composite screen meshes and the like. The single-layer silk screen has the characteristics of simple structure, large water permeability and convenience for cleaning, but the strength is poor, the filter screen is damaged after the equipment runs for about 6 months, the equipment needs to be replaced, and the maintenance cost is too high; the sintered silk screen and the punching plate composite silk screen are formed by combining and sintering various filter screens and punching plates to form an integral rigid filtering material, and although the mechanical strength is greatly improved, the method has the defects of low water permeability, complex structure and the like, and the processing cost is higher, so that the design and the structure of the existing filter screen need to be further innovated and improved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a seamless welding precision filter screen for water treatment, which can effectively solve the problems of poor strength of single-layer filter screens and low water permeability of multi-layer filter screens.

In order to realize the above purpose, the technical scheme of the utility model is, a seamless welding precision filter screen for water treatment, including lower floor's support wire, upper skeleton wire and filter screen, lower floor's support wire equipartition is arranged in the direction of latitude, places the filter screen on the lower floor's support wire, and the up end of filter screen has the upper skeleton wire of longitude direction equipartition range, and upper skeleton wire and lower floor support wire longitude and latitude overlap joint welding together constitute the integral type structure.

The utility model discloses simple structure, convenient operation had both realized the high flux of individual layer silk screen, had possessed the mechanical strength of sintering silk screen again, had improved work efficiency greatly, had prolonged the life of filter screen.

Drawings

Fig. 1 is a perspective view of the present invention.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

The utility model discloses in implementing, give in combination with figure 1, a seamless welding precision filter screen for water treatment, including lower floor's support wire, upper skeleton wire and filter screen, lower floor's support wire 3 equipartition is arranged on the latitude direction, places filter screen 2 on lower floor's support wire 3, and filter screen 2's up end has upper skeleton wire 1 that longitude direction equipartition was arranged, and upper skeleton wire 1 and the welding of lower floor's support wire 3 longitude and latitude overlap joint department are in the same place, constitute the integral type structure.

In order to ensure the implementation effect, the distance between the metal wires 1 of the upper layer framework is 25mm, and the distance between the metal wires 3 of the lower layer support is 25 mm.

The upper framework metal wire 1 and the lower support metal wire 3 are both round tubes with the diameter of 2.24 mm.

The filter screen 2 selects the corresponding composite filter screen according to different filtering precision, the composite filter screen is formed by overlapping and fixing at least 2 layers of metal wires, and an anti-corrosion ceramic layer is sprayed on the surface.

The utility model discloses when concrete production, transversely put into forming device internal fixation with the lower floor support wire, then according to the filter fineness grade, lay the filter screen and fix on the lower floor supports the wire, vertically put into forming device internal fixation with the upper strata support wire, push welding position department to the aforesaid wholly, support wire, filter screen and the lower floor with the upper strata and make the compaction of wire longitude and latitude overlap joint department to the welding is in the same place.

According to the above, the utility model discloses having combined both advantages of individual layer silk screen and sintering silk screen, both having realized the high flux of individual layer silk screen, having possessed the mechanical strength of sintering silk screen again, improved 1.5 times with the unit area handling capacity, the whole volume of equipment reduces by a wide margin, and energy-conserving increase is showing, has prolonged the life of filter screen, has apparent society and economic benefits.
