Abstract
The utility model discloses a stainless steel mesh plate for replacing a pebble underpinning layer, comprising grille bars and a reinforcing rib for fixing the grille bars, wherein the grille bars are regularly arranged on the reinforcing rib at intervals, and the cross section of each grille bar is wedge-shaped. The grille bars are regularly arranged on the reinforcing rib at intervals to form the mesh plate, and the mesh plate is fixed on a filter plate by uniformly-arranged supporting pieces and a fixing bolt to replace the traditional pebble underpinning layer, so that water and gas distribution is more uniform in the process of back wash, fiber filter media loaded above the screen plate is avoided to block, and the filter effect is ensured. Meanwhile, as the cross section of each grille bar is wedge-shaped, air bubbles can be effectively cut in back wash, the uniformity of the water and gas distribution is increased, phenomena of dead zones and short circuits are prevented, and the effect of back wash is improved.
Description
Technical field
The utility model belongs to water-treatment technology field, particularly a kind of stainless steel filtering net plate that replaces the cobble supporting layer, and can be effective to feed water filtering ponds and municipal sewage one-level A mark the various fibre filters of handling.
Background technology
Giving water treatment and sewage treatment area, comet type fibre filter (being D type filter tank) is the filtration facility of using always.The comet type fibre filter comprises filter tank, filter material layer, filtrate supporting layer and backwash water distribution distribution device, and wherein filter material layer is divided into bulky grain filter material layer and granule filter material layer, and the right supporting layer of ovum is set under filter material layer, is used for the support filtrate.This employing cobble is as the filter tank of filtrate supporting layer, and the cobble supporting layer easily causes the water distribution gas distribution inhomogeneous, and the unity piece is easily mixed, entangled to fiber filtering and cobble, influences filter effect.In addition, filter and backwash process in, fiber filtering easily runs off, and causes the filter tank to stop up, formation dead band or short circuit make the filter tank can't operate as normal, and the backwashing water consumption energy consumption is huge.
The utility model content
The purpose of this utility model provide a kind of simple in structure, water distribution gas distribution evenly, the stainless steel filtering net plate of the replacement cobble supporting layer of good filtration effect.
For achieving the above object, the technical solution of the utility model is: a kind of stainless steel filtering net plate that replaces the cobble supporting layer, comprise the reinforcement of grid bar and fixed grating grizzly bar, and grid bar rule, be arranged on the reinforcement at interval, described grid bar cross section is wedge shape.
Described grid bar is parallel, equidistantly be installed on the reinforcement, and the grid bar is vertical mutually with reinforcement.
Described sieve plate is fixed on the filter plate by set bolt, and one on bolt is fixed on the sieve plate, and the other end is fixed on the filter plate.
Be provided with support member between described sieve plate and the filter plate, bolt is located on the support member, and sieve plate evenly is laid on the support member.
Compared with prior art, the utility model has the advantages that:
1, rule, interval arrange that the grid bar forms sieve plate on reinforcement, and sieve plate is fixed on is used for replacing the cobble supporting layer on the filter plate, make that the water distribution gas distribution becomes more even in the filter process, avoid fiber filtering and the cobble of sieve plate top to mix, entangle the unity piece, the assurance filter effect; Simultaneously, grid bar cross section is wedge shape, can effectively cut bubble when backwash, improves water distribution gas distribution uniformity, prevents dead band and short circuit phenomenon, improves backwash effect.
2, be provided with support member between sieve plate and filter plate, by being located in the fixing sieve plate of set bolt on the support member, fixed form is simple, and adjustment, easy accessibility.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is a fixedly schematic diagram of the present utility model.
The specific embodiment
As the stainless steel filtering net plate of Fig. 1, Fig. 2, replacement cobble supporting layer shown in Figure 3, it comprises reinforcement 1 and grid bar 2, and grid bar 2 parallel, equally spaced regular arrangement and guarantee that grid bar 2 is mutual vertical with reinforcement 1 on reinforcement 1.The cross section of grid bar 2 is wedge shape.As shown in Figure 4, be provided with support member 4 between grid bar 2 and the filter plate 3, grid bar 2 is fixed on the filter plate 3 by set bolt 5, bolt 5 is located on the support member 4, one of bolt 5 is fixed on the grid bar 2, and the other end is fixed on the filter plate 3, and grid bar 2 evenly is paved with support member 4.
Reinforcement 1 and grid bar 2 all adopt stainless steel, intensity height, wear-resistant, corrosion-resistant, durable in use.The utility model can be formed large-sized by the undersized welding of polylith, and its area is from 1～20m
2Etc., specifically size can not decided according to the filter tank size; The thickness of reinforcement 1 and grid bar 2 can be decided according to the height of carrying filtrate, selects for use in 2～8mm scope usually; The spacing of adjacent grid bar 2 is slightly less than comet filtrate cometary nucleus diameter (being approximately 1-4mm).
Claims (4)
1. stainless steel filtering net plate that replaces the cobble supporting layer is characterized in that: comprise the reinforcement of grid bar and fixed grating grizzly bar, grid bar rule, be arranged on the reinforcement at interval that described grid bar cross section is wedge shape.
2. the stainless steel filtering net plate of replacement cobble supporting layer as claimed in claim 1 is characterized in that: described grid bar is parallel, equidistantly be installed on the reinforcement, and the grid bar is vertical mutually with reinforcement.
