Abstract
The utility model relates to a device for separating a suspended particle from liquid by means of filtration especially a filtering device for regenerating a filtering material. A compound air-water back washing filtering brick is one hollow long cube, one end of the compound air-water back washing filtering brick is provided with a connection layer, the outer surface is provided with a reinforcing rib, and the inner pat of the filtering brick is divided into one distributing channel and two mixed channels by an interlayer. Eyelets are arranged on an upper layer and the interlayer, the filtering brick can realize that water and air are evenly distributed with small head loss, and the gas and the water can simultaneously carry out back washing. The utility model has the advantages of firm structure, good appearance and quality, smooth eyelets, favorable back washing effect, long service life, etc.
Description
The utility model relates to the device with the method separate out suspended particle from liquid that filters, and especially makes the filter of filtering material regeneration.
In giving water treatment procedure, filtration is one of vital process, so field of water treatment is attached great importance to the design and the research of filtering ponds.And the existing filter that can make media regeneration, or the loss of flood peak is bigger, or water distribution owes evenly, or air water can not recoil simultaneously.
The purpose of the utility model is to provide a kind of and realizes that with the less loss of flood peak water distribution uniformity gas distribution, air water recoil simultaneously, the novel preferably filter of backwash effect.
Compound air-water backwashing filter block is the long cube of a hollow, and an end has articulamentum, and there is reinforcement the outside, and interlayer is separated into a distributing channel and two mixing canals with the inside of filter block, has eyelet on upper strata and the interlayer.
Below in conjunction with embodiment shown in the drawings, the utility model is explained in detail.
Accompanying drawing 1 is the utility model schematic diagram, accompanying drawing 2 be the utility model A to view, accompanying drawing 3 is interlayer and eyelet schematic diagram thereof.Among above-mentioned each figure; 1, interlayer, 2, distributing channel, 3, mix canal, 4, articulamentum, 5, the upper strata, 6, eyelet, 7, reinforcement.
Shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, compound air-water backwashing filter block is the long cube of a hollow, and an end has articulamentum 4, and there are some reinforcements 7 outside.Interlayer 1 is separated into a distributing channel 2 and two mixing canals 3 with the inside of filter block.Have several eyelets 6 on upper strata 5 and the interlayer 1.
As shown in Figure 1, tail connects first of two filter blocks of articulamentum 4 realizations.Reinforcement 7 has 6, evenly arranges, is intended to strengthen the mechanical strength of filter block.
As shown in Figure 2, two interlayers 1 are separated into a distributing channel 2 and two mixing canals 3 with the inside of filter block.The cross sectional shape of distributing channel 2 is equilateral triangle, and the cross sectional shape that mixes canal 3 is del.
Shown in accompanying drawing 1 and accompanying drawing 3, have 72 eyelets on the upper strata 5.Have totally 34 of the eyelets 6 of three kinds of different-diameters on every interlayer 1.
Filter block is widely used in all kinds of filter tanks except making by different appearance and size the product of multiple model for making this product, also makes center filter block, angle filter block, limit filter block etc., makes it to form tandem product.
Filter block adopts the moulding of ABS engineering plastics integral molded plastic, is fastened in the filter tank with bolt and nut.
During backwash, air cushion layer is formed at the top of distributing channel 2, and the bottom is a water layer.When air water mixed flushing, after the mixing, 5 eyelet was to filtering layer water distribution uniformity gas distribution through the upper strata in mixing canal 3 for the eyelet 6 of G﹠W by interlayer 1.
Obviously, the utility model can be realized the water distribution uniformity gas distribution with the less loss of flood peak, and air water backwash simultaneously has firm in structure, advantages such as presentation quality good, eyelet is smooth, backwash effect is good, long service life.
Embodiment shown in the drawings is the compound air-water backwashing filter block of ZSIII type, and appearance and size is 600 * 280 * 250; The diameter 5 of upper strata eyelet, percent opening 0.79, discharge coefficient 0.79; The interlayer eyelet is: 6 of diameter 22,12 of diameter 5.8,16 of diameter 4.5, percent opening 1.37, discharge coefficient 0.8.
