Abstract

The utility model provides a lower mouth of a river filter screen, includes the body, its characterized in that the body is vertically and horizontally staggered's wavy metal strip through one shot forming forging and pressing, the metal strip is wavy and is certain inclination interconnect, be one on one the shape between two adjacent arcwall faces on the metal strip, this filter screen passes through drainage face guide rivers flow direction, avoids the vertical stroke drainage to the hair contained angle of scraping between drainage face and the drainage face effectively promotes the drainage effect of filter screen.

Description

Filter screen for sewer

Technical Field

The invention relates to the field of filter screens, in particular to a sewer port filter screen which is mainly suitable for a floor drain filter screen in a bathroom or a kitchen.

Background

Various sewer floor drains of using at present simple structure, the filter effect to dregs, hair is not good, dregs, hair directly enter into the sewer easily, and the clearance of being not convenient for causes the sewer to block up, uses very inconveniently, perhaps floor drain structure is complicated, and is better to the filter effect of dregs, hair, but the clearance of being not convenient for, uses and has received certain restriction.

Most of traditional floor drain filter screen pieces are common metal wires and are connected in a cross mode, traditional filter screen water flow is easy to directly leave poor filtering effect, and sewer blockage is caused very easily.

Disclosure of Invention

In order to solve the defects of the prior art, the invention provides a filter screen for a drainage port, which is integrally formed by combining wavy three-dimensional metal strips, can effectively solve the problem of poor filtering effect, and the metal strips are designed in a flat shape, and a drainage surface is formed between the adjacent metal strips, so that direct flushing type drainage is avoided, hair or foreign matters are conveniently filtered, and a good filtering effect is provided.

The utility model provides a lower mouth of a river filter screen, includes the body, its characterized in that the body is vertically and horizontally staggered's wavy metal strip through one shot forming forging and pressing, the metal strip is wavy and is certain inclination interconnect, be one-on-one shape between two adjacent arcwall faces on the metal strip, specific this filter screen that says so is three-dimensional fish scale form.

Preferably, the adjacent metal strips are connected in an up-down mode.

Preferably, the metal strip has a certain width.

Preferably, the metal strip is made of stainless steel.

Preferably, the metal strip is provided with a drainage surface, and the drainage surface is an upward inclined surface of the metal strip.

Preferably, the drainage surface and the drainage surface are provided with a hair hanging included angle, and the surface of the hair hanging included angle is irregular.

Preferably, the drainage surface is provided with a convex point or a hook.

Preferably, the filter screen is formed by one-time forging and pressing, and the metal strip is formed by cutting for forging and pressing.

Preferably, a filter hole is formed between the metal strips, and the filter hole is formed by staggered gaps between the adjacent metal strips.

Compared with the prior art, the gain effect of the invention is as follows:

this filter screen passes through wavy metal strip and connects the formation, the metal strip has certain width, and the metal strip is certain angle slope, an arc drainage face has promptly on the metal strip after the slope, drainage face can prevent effectively that rivers from directly not having any direct downflow that stops when dashing, design into shape cross connection one on the other on the metal strip between two adjacent arcwall faces, wholly be fish scale form design, and two liang of cross connection between two adjacent metal strips, be convenient for the filtration of hair and foreign matter, this filter screen possesses simple structure for traditional filter screen, and filter effect adds advantages such as.

Drawings

Fig. 2 shows a schematic view of the drainage surface of the screen.

Fig. 3 is a schematic side view of the screen.

Detailed Description

As shown in figure 1, a drainage is filter screen, including the body, shown body forms wavy metal strip 1 through forging and pressing, and metal strip 1 presents vertically and horizontally staggered mode interconnect, and shown metal strip 1 and metal strip joint gap department establish worry hole 3, and two adjacent arcwalls on shown metal strip are one on one shape, and two liang of arcwalls between metal strip 1 and the metal strip 2 are connected relatively promptly, make worry hole 3 between the arcwall present the rhombus shape.

As shown in fig. 3, filter screen drainage face schematic diagram, shown metal strip is for possessing certain width metal strip, be certain inclination interconnect between the metal strip, arcwall face between the shown metal strip is drainage face 4 promptly, drainage face 4 is the tilt up, drainage face 4 is the arc slope form, form between drainage face and the drainage face and hang a mao contained angle 5, scrape the irregular contained angle of 5 bit surfaces in mao contained angle, scrape the regional surface of mao contained angle and carry out the repression through equipment when forging and pressing and form irregular surface, be convenient for scrape mao.

The surface of the shaving included angle 5 can be a convex point type or an irregular inverted hook-shaped convex point.

Because the drainage face possesses certain width area to the arc form is personally submitted in the drainage, when rivers directly dash, can be blockked by the drainage face, the water of the backward flow of formation can be followed the hair contained angle department of scraping between drainage face and the drainage face and down flowed, and the hair or the foreign matter of final aquatic are caught on by the bump of scraping hair contained angle department, play the effect of filtering hair.

Fig. 3 shows a schematic diagram of the side of the filter screen, wherein the side of the filter screen is wavy, the filter screen is a double-sided filter screen, and both sides of the filter screen can be used.

While the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and modifications can be made, and equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
