Description
Technical field
The present invention relates to a kind of filter block, more particularly, to a kind of filter block for filter tank water distribution gas distribution system.
Background technology
Denitrification deep-bed filter is to collect the processing unit that biological denitrificaion and filtering function unite two into one, and is denitrogenation and mistake
Filter the advanced handling process of one.
Filtrate uses 2~3mm quartz sand media, and filter bed depth is usually 1.83m, and filter tank can ensure water outlet SS
Less than below 5mg/L.Most filter tank top layers are easy to block or hardened, and head is lost quickly, and unique
Homogeneous quartz sand allow solid impurity to pass through the top layer of filter bed, in the filtrate for going deep into filter tank, reach that whole filter tank is indulged
The excellent effect of deep retention solids.
In the course of work of filter tank, backwash stage is very important, if water distribution gas distribution is uneven, is easily made
Into the short stream of filter tank backwash, backwash is not thorough, is normally run to filter tank and brings puzzlement.So water distribution gas distribution system water distribution
Uniformity, install simple degree be very important for filter tank.
Found in production practices, current filter tank water distribution gas distribution system main product mainly has：Strainer head, wear
The various forms such as Kong Guan, filter plate, water distribution uniform air distribution is higher, but there is the shortcomings of installing complexity, maintenance difficulty.
Chinese patent ZL201320711037.6 discloses a kind of denitrification deep-bed filter filter block, including in strip
The brick body of shape, the top of brick body has a packing groove, and the bottom of brick body has multiple brick pin, adjacent two brick pin it
Between there is gap, the side of brick body has neck, and the opposite side of brick body has the dop matched with neck, when one
After the dop of block brick body side is embedded into the neck of another piece of brick body opposite side, two pieces of brick bodies are connected.Though the patent
Filter tank bottom so can be neatly laid on, but because of the clamping engagement structure on its laterally and longitudinally both direction all
It is fixed, so as to cause it not to be particularly convenient when mounted.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is matched somebody with somebody for filter tank
The filter block of water gas distribution system.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of filter block for filter tank water distribution gas distribution system, including filter block body, the top of described filter block body is set
There is packing groove, longitudinal both sides of described filter block body lower part are interval with multiple supporting legs, are additionally provided with filter block
For with other filter blocks are connected agrees with mechanism, this agrees with, and mechanism includes laterally agreeing with component and group is agreed with longitudinal direction
Part, described transverse direction agrees with transverse ends correspondence position and the size matching that component includes being separately positioned on filter block body
Tang and recess, component is agreed with described longitudinal direction to be included being arranged on locator card on longitudinal side of filter block body
Groove, being provided with the para postion of longitudinal opposite side of filter block body is used to coordinate fixed may be reversed with locating groove
Buckle.Two pieces of adjacent in the horizontal filter blocks, the tang of one of filter block docks the recess of another piece of filter block,
So as to realize the connection of two pieces of filter blocks in the horizontal；Two pieces of adjacent in the vertical filter blocks, then be one of filter block
Buckle upset insertion locating groove in, so as to realize the connection of two pieces of adjacent filter blocks in the vertical.
Longitudinal side of described filter block body is provided with least one locating groove and at least one buckle, in filter block
The buckle or locating groove of Corresponding matching are additionally provided with longitudinal opposite side of body, described locating groove is with being buckled in
It is arranged at intervals on the same side of filter block body.Such setting can cause the both sides of filter block body in the vertical with indulging
Relatively more balance and stability is connected between two pieces of adjacent other filter blocks.
Provided with horizontal arch door shape passage between the supporting leg of longitudinal both sides of filter block body lower part；
V-type passage is formed between adjacent two supporting leg that filter block body the same side is distributed.Arch door shape passage and V
Type passage is mainly used in water distribution gas distribution.
Described arch door shape passage is by integral type in the superstructure for the arc that Open Side Down and in wide at the top and narrow at the bottom
Trapezoidal substructure composition.Described supporting leg is provided with six on filter block body the same side, wherein, it is distributed in
The length of two supporting legs at two ends is less than the length for four supporting legs for being distributed in centre.
Longitudinal both sides of described filter block body are additionally provided with distributing trough above supporting leg.Distributing trough set can to
Air intensity and backwash intensity during gas and water distribution are compensated, so as to ensure the uniformity of distribution and water distribution.
The projection that described filter block body is additionally provided with longitudinal both sides on projection, both sides mutually staggers, and makes longitudinal direction
The wide holes of 2~3mm are formed between upper two adjacent filter blocks.The hole of projection cube structure formation can be prevented effectively
Hole of the filtrate through two filter blocks, it is to avoid hole is blocked, and then the effective uniformity for ensureing water distribution gas distribution
And stability.
The projection of filter block body the same side is interval with least two pieces.
High grade plain concrete is filled with described packing groove.High grade plain concrete is filled in packing groove, not only
Counterweight can be realized, and improves the structural strength of filter block body, its weight capacity is added.
Compared with prior art, the present invention has advantages below：
(1) by setting the transverse direction being made up of tang and recess to agree with component, and by locating groove and buckle group
Into longitudinal direction agree with component, meanwhile, buckle using turnover form set, in this manner it is ensured that filter block is in horizontal stroke
To with close, the neat and Fast Installation on longitudinal direction.
(2) arch door shape passage, V-type passage and distributing trough etc., the particularly setting of distributing trough, can be in water distribution
During gas distribution, the intensity of water distribution gas distribution can be effectively compensated, so that the uniformity of strong guarantee water distribution gas distribution.
(3) filter block is fixed on horizontal and vertical by agreeing with mechanism, is ensureing filter block stable setting on filter tank
Meanwhile, the dimensionally stable of the passages such as the hole that the water supply existed between adjacent filter block, gas pass through is also ensure that, it is constant
Shape, so as to ensure the uniformity and stability of water distribution gas distribution.
