SE508640C2 - Sieve for floor well - Google Patents

Abstract

In the sieve periphery (12) is an outer edge (14), which prevents waste water running inwards under it. Its slots (13) are radially positioned and are also at right-angles to the direction of throughflow of the waste water. The long sides of the slots are angled to produce an increased water throughflow. In this way, the sieve separates hair and other solid particles on its upper side, whilst waste water runs downwards into the floor well.

Description

508 640 z An embodiment is shown in the accompanying drawing where: Figure 1 shows the floor drain screen seen from above.

Figure 2. shows a vertical section through the floor drain screen.

Figure 3. shows a vertical detail section through the floor drain screen.

Figure 1. shows a floor drain screen (12) seen from above, where its seats (13) are radially placed on the surface of the floor drain screen (12) and in the embodiment lined up in two circular shapes around the center of the floor drain screen (12). On the upper side of the floor drain screen (12) there is a grip (15) by means of which the floor drain screen (12) can be fl surface.

Figure 2. shows a vertical section through the floor drain screen (12) which lies on top of a floor drain (16) and where the floor drain screen (12) is designed so that its outer edge (14) is angled towards the top of the floor drain so that it abuts the floor drain (16). The figure shows the design of the floor drain screen (12) as it is not affected by the weight and properties of the material it is made of, under such an influence the floor drain screen (12) will abut against the floor drain (16). The figure also shows a section of the slits (13) in their longitudinal direction.

Figure 3. shows a vertical detail section through the floor drain screen (12), with a cross-section in the width direction of the slots (13) and shows the angled long sides (17) of the slots.

Claims (1)

508 640 CLAIMS Floor well screen (12) made of flexible, sheet-shaped material and intended to cover the lid of existing floor wells, the screen (12), which is circular, being provided with through-openings (13) for water flow, characterized in that the openings ( 13) are in the form of slits, which are extended in the radial direction and which have a width which allows great water flow but which prevents hairs and other debris from flowing through. wherein the extent of the slots (13) depending on the force of Corioli becomes substantially perpendicular to the water flow over the screen (12). and in that the screen (12) at the outer edge area (14) has a decreasing thickness in the direction of the circumferential edge for easier adaptation of the screen (12) connection to the substrate and for facilitating the flow of water up over the screen (12). Floor well screen (12) according to claim 1, characterized in that the longitudinal edges (17) of the slots (13) are angled for preheated water flow. Floor well sieve (12) according to claim 1 or 2, characterized in that the sieve (12) has such a weight that it is kept flat on the floor well cover by this weight and by the supreme water.
