Abstract

The utility model belongs to an improvement of air-water backwashing filter brick regenerating filter material and arranged at the bottom of a filter tank. A groove is arranged on an apical angle of a Y-shaped interlayer of an oblong cavity body made of high density polyethylene material, an upper layer hole eye is arranged in the groove, and a rubber ring is arranged at one end of a plug of the cavity body. Thus, smaller water head loss of filter bricks can be realized, uniform water distribution and gas distribution can be realized, backwashing effect of the utility model is good, and the utility model has the advantages of light weight, easy installation, fastening frame, etc.

Description

Compound water and air distributing backwash filter block

The utility model relates to the method that is used for the filtering device from liquid separate out suspended particle, especially places the filtering ponds bottom to make 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, the loss of flood peak is bigger, or water distribution owes evenly, or air water can not recoil simultaneously.On September 4th, 1994, the applicant has applied for " the compound air-water backwashing filter block " patent that the patent No. is ZL942201299.It has solved the problem of above-mentioned existence preferably, has realized water distribution uniformity, gas distribution, the purpose of air water backwash simultaneously.But also exist some shortcomings, as the filter block Heavy Weight, transportation is installed inconvenient, and the connection tightness between the filter block is not high, the easy obstruction of eyelet etc.

The present invention's purpose is to provide a kind of easy for installation, eyelet to be difficult for stopping up, and water distribution, gas distribution are more even, the better filter of backwash effect.

The technical solution of the utility model is such: it is a rectangular cavity body, and two ends are provided with the hollow socket and the plug of connection; Be provided with " people " font interlayer in the cavity, interlayer is separated into a distributing channel and two mixing canals with inside cavity, and there is reinforcement the cavity outside; Upper strata and interlayer have eyelet, and its eyelet at the middle and upper levels is arranged in the equally distributed pit, to prevent being covered obstruction by the flat cobble in the boulder bed.Be provided with the groove that the cross section is a spill on herringbone interlayer top, make both sides mixing canal end face be higher than the gable-top of distributing channel, it is stable, even to reach the distribution layer.

Peg graft conveniently in order to make between the filter block, better tightness, this reality are made the novel rubber ring that is embedded with on plug, itself and another filter block spigot seal is connected.

Filter block of the present utility model adopts high-density polyethylene material, by low foaming one-shot forming.

Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is described in further detail.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is eyelet and pit enlarged diagram.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is that the B of Fig. 1 is to schematic diagram.

Fig. 5 is a socket C partial enlarged drawing among Fig. 1.

Fig. 6 is a plug D partial enlarged drawing among Fig. 1.

As Fig. 1, shown in Figure 3, compound air distribution and water distribution backwash filter block is a rectangular cavity body, two ends are provided with hollow attachment plug 1 and socket 8, there is equally distributed reinforcement 4 the cavity outside, be provided with " people " font interlayer 10 in the cavity, interlayer 10 is separated into two mixing canals 9 of a distributing channel 11 with inside cavity, and the upper strata 3 of cavity and interlayer 10 have the eyelet 5 of water distribution, gas distribution, its at the middle and upper levels 3 eyelet 5 place in the equally distributed pit 6, see Fig. 2; This pit 6 is that the flat cobble in filter block end face 3 boulder beds covers and blocks eyelet 5.Having the cross section on the top of the interlayer 10 of " people " font is the groove 7 of spill, and this groove 7 makes both sides mixing canal 9 end faces be higher than the gable-top of distributing channel 11, and it is more stable, even to reach the distribution layer.

The percent opening window of eyelet 3 footpath size and deciding, every interlayer has the eyelet 5 of three kinds of different-diameters, specifically sees Table 1.

Table 1

6	1.44	22×8、6.0×16、3.5×12	1.46

Referring to Fig. 4, Fig. 6, the outer wall of plug 1 has two ring recess, and each ring recess is embedded with the rubber ring 2 that butylbenzene is a material, fastening, the sealing of pegging graft between the socket 8 of assurance and another filter block.Socket 8 inwalls are stairstepping, see Fig. 5, and its stage plays position-limiting action, and the internal diameter of socket 8 matches with size, the shape of plug 1.

Filter block of the present utility model adopts high-density polyethylene material, by the foaming one-shot forming.

Obviously, the utility model is compared with original filtering brick back washed by compound air-water, has lightweightly, install, convenient transportation, and fastening structure, the advantage such as backwash effect is good, and also water distribution, gas distribution are more even.
