Abstract
The utility model discloses a kind of water filtering cap, crown and hollow conduit are made as one, and filter grid cylinder is fastened and connected with crown after being set on hollow conduit periphery; Hollow conduit bottom is provided with external screw thread, and cap seat bottom is nut, coordinates with the external screw thread of hollow conduit, and pushes against filter grid cylinder by water stop spacer and be arranged on supporting plate; Filter grid cylinder periphery wall is the vertical face of cylinder, barrel is evenly equipped with some filters seam, barrel periphery is provided with circumferential rib.The utility model is arranged on after on supporting plate, and the straight tube wall of filter grid cylinder can not bear the pressure of filter material layer, therefore goes for the severe duties such as boulder bed.Each parts of the present utility model all adopt nylon material machine-shaping, and compared to existing ABS material, intensity improves greatly, thus effectively improve reliability and the life of product of water filtering cap.
Description
Technical field
The utility model relates to field of environment protection equipment, especially a kind of water filtering cap for filtering.
Background technology
Water filtering cap is widely used in the water treatment facilities of the industries such as petrochemical industry, medicine food, sewage disposal, waterworks, belongs to common components.In water treatment facilities, the porous supporting plate usually bottom filter material layer arranges some water filtering caps; During work, the process water bed of material after filtration from top to bottom, then enter water filtering cap by the osculum on water filtering cap, then discharged by mozzle.According to technological requirement, after multiple times of filtration, backwash to be carried out to filter material layer, make its unimpeded or activity recovery.During backwash, current through water filtering cap ejection, rinse filter material layer from bottom to top.Existing water filtering cap mostly is turriform or umbrella shape profile, and the cone wall of such water filtering cap will be subject to the pressure of filter material layer, and especially when bottom filtrate is boulder bed, the load-bearing of cone wall is larger; Existing water filtering cap utilizes the manufacture of ABS engineering plastics more, intensity is poor, easy cracked, very easily aging, corrosion-resistant under local function, filtrate seepage and inside and outside water quality is caused to confuse pollution, cause inefficacy, and change water filtering cap and also need cleaning to remove filtering layer, take time and effort, maintenance cost is high.
Utility model content
The applicant is for shortcomings such as easy cracked inefficacies after the load-bearing of above-mentioned existing taper water filtering cap, and provide a kind of water filtering cap rational in infrastructure, sidewall is straight tube structure, can prevent from being pressed collapse cracked.
The technical scheme that the utility model adopts is as follows:
A kind of water filtering cap, crown and hollow conduit are made as one, and filter grid cylinder is fastened and connected with crown after being set on hollow conduit periphery; Hollow conduit bottom is provided with external screw thread, and cap seat bottom is nut, coordinates with the external screw thread of hollow conduit, and pushes against filter grid cylinder by water stop spacer and be arranged on supporting plate; Filter grid cylinder periphery wall is the vertical face of cylinder, barrel is evenly equipped with some filters seam, barrel periphery is provided with circumferential rib.
Further improvement as technique scheme:
The wall thickness of described filter grid cylinder is 1 ~ 3mm.
The aperture widths of described filter seam is about 0.2 ~ 0.8mm.
Described crown and hollow conduit, cap seat and filter grid cylinder adopt nylon material manufacture.
The beneficial effects of the utility model are as follows:
The utility model is arranged on after on supporting plate, and the straight tube wall of filter grid cylinder can not bear the pressure of filter material layer, therefore goes for the severe duties such as boulder bed.Each parts of the present utility model all adopt nylon material machine-shaping, and compared to existing ABS material, intensity improves greatly, thus effectively improve reliability and the life of product of water filtering cap.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, crown 1 and the hollow conduit 5 of water filtering cap described in the utility model are made as one, and filter grid cylinder 2 is fastened and connected with crown 1 after being set on hollow conduit 5 periphery.Hollow conduit 5 bottom is provided with external screw thread, and cap seat 4 bottom is nut, coordinates with the external screw thread of hollow conduit 5, and pushes against filter grid cylinder 2 by the water stop spacer 3 of quality of rubber materials and be arranged on supporting plate.
Filter grid cylinder 2 of the present utility model is tubular profile, and periphery wall is the vertical face of cylinder, upper and lower equal diameters, and wall thickness is 1 ~ 3mm, is preferably 2mm, barrel is evenly equipped with some filter seams 6, and the aperture widths of filter seam 6 is 0.2 ~ 0.8mm, is preferably 0.5mm; A few ribs 7 are provided with, to increase the intensity of tubular in barrel periphery.The each part of the utility model all adopts modified nylon materials manufacture, and compared to traditional ABS material, corrosion resistance and toughness greatly improve, and can effectively increase life of product and reliability.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, when without prejudice to the utility model spirit, the utility model can do any type of amendment.
