Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, is a schematic view of the overall structure of the water supply plant filter tank backwashing drainage filter material intercepting device of the present invention; a chamber 11 is arranged in the filter 1 and used for storing filter materials (such as active carbon and the like); the utility model discloses an improvement part does, at the water drainage tank both sides top in filtering pond 1, installs filter equipment 2 additional respectively.

As shown in fig. 2, it is a schematic cross-sectional view of the filter material intercepting device for backwashing and draining of the filter tank of the water supply plant of the present invention; comprises a filtering bracket 21 which is made of stainless steel plate by bending; the middle part of the filtering bracket 21 is provided with a filtering window 211, and the top part of the filtering bracket is folded to form a door-shaped reinforcing top 212; for the convenience of installation, the filter support 21 is generally made longer, and a plurality of reinforcing ribs 213 are welded at intervals for reinforcing in the middle of the filter support, and the reinforcing ribs 213 connect the cross section of the whole filter support 21 together.

The filtering bracket 21 is fixed on the top of the filtering chamber 1 through a mounting fastener 22, or fixed on the slope outside the top of the filtering chamber 1 as shown in the figure, so that the filtering bracket 21 on the 2 side forms a V shape, and the filtering area is increased. The mounting fastener 22 is typically a stainless steel expansion bolt, one end of which is mounted in the filter chamber 1, and the exposed part of which is used for fixing the filter support 21.

When the filter support 21 is arranged on a slope on the outer side of the top, the upper end of the bottom mounting surface of the filter support 21 is aligned with the top of the filter tank 1, so that dead corners are avoided, filter materials are deposited at the dead corners, and the filter materials cannot be cleaned.

Further, a regulating pad 23 is arranged between the bottom of the filtering bracket 21 and the filtering pool 1; the adjusting pad 23 is made of a high polymer anticorrosive material, has certain elasticity, and can be used for leveling the top mounting plane of the filter tank 1 through the adjusting pad 23. When the adjusting pad 23 is adopted for installation, the adjusting pad 23 is directly contacted with the filter tank 1, and the corners are aligned as far as possible, so that dead corners are eliminated, and filter materials are prevented from being deposited.

Further, referring to fig. 3, a layer of stainless steel filter screen 24 is covered on the main body of the filter support 21, and the filter screen 24 is tiled to cover the filter window 211 through a stainless steel cover plate 25; the cover plate 25 is a hollow cover plate shaped like a Chinese character 'hui', and a cavity communicated with the filtering window 211 is arranged in the middle of the cover plate; the cover plate 25 is fixed to the main body of the filter holder 21 by a ring of cover plate fasteners 26, thereby securely fixing the filter net 24.

Because the filter 1 of a water plant is generally long, a plurality of sections of the filter supports 21 are required to be spliced, and adjacent 2 filter supports 21 can be connected together through the support connecting fasteners 214 to form a complete filter device for filtering and protecting the top of the whole filter 1. Correspondingly, as shown in fig. 4, the mounting hole of the bottom surface of the filter holder 21 for passing through the mounting fastener 22 is an elongated adjustable mounting hole 215, so that the mounting height can be adjusted, and the error of fixing the mounting fastener 22 on the filter chamber 1 can be corrected.

Through the utility model discloses, increase the drain tank wall of original filtering pond 1, and form and supply back flush rivers to go out, and the filter material is held back the filtration that gets off by filter screen 24, has reduced the waste of filter material because of spilling over and causing. After the back washing is finished, the filter material retained on the filter device 2 is washed by the water gun from the outside, and then the filter material can return to the cavity 11.
