Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1:
To stream denitrification filter pool inlet channel water dispensing apparatus, such as Fig. 5, the casing including being embedded in 1 bottom of distributing channel under one kind
11, the bottom of distributing channel 1 is extended in one end of casing 11, such as Fig. 1 and Fig. 2, and in one end of stretching by being fixed on casing 11
On fixing piece 12 be arranged with hose 13, hose 13 extends into denitrification filter pool 2 and is located at liquid level hereinafter, being exposed at this time
Only hose 13 in air, casing 11 are made in distributing channel 1 and using stainless steel, reduce the aging of casing 11, hose
13 is non-aging, and after 13 aging of hose, it is only necessary to be removed hose 13 from casing 11 by fixing piece 12, hose
13 replacement costs are low, easy to operate.
Such as Fig. 1, water flows through hose 13 from the casing 11 of 1 bottom of distributing channel and enters in denitrification filter pool 2, due to do not have water from
Distributing channel 1 arrives the drop oxygenation situation of denitrification filter pool 2, therefore can reduce the dissolved oxygen of denitrification filter pool 2, promotes denitrification
Anaerobic environment in filter tank 2 creates the living environment for being conducive to denitrifying bacteria, improves denitrification filter pool 2 and removes total nitrogen
Effect.
Such as Fig. 2, fixing piece 12 includes that 13 sets of hose the first arc pressure rings 121 and the second arc outside casing 11 are arranged in
Pressure ring 122, the first arc pressure ring 121 and the second arc pressure ring 122 are oppositely arranged on 13 outer wall of hose and equal in opposite side
Equipped with connecting plate 123, there are gaps between two connecting plates 123, and two connecting plates 123 are connected by connection bolt 124, even
First arc pressure ring 121 and the second arc pressure ring 122 are pressed on hose 13 by connecting bolt 124, and then hose 13 is pressed on
11 outer wall of casing, so that the water flowed out out of casing 11 flows into denitrification filter pool 2 along hose 13.
Such as Fig. 2, casing 11 is equipped with several raised 111 in the outer wall connecting with hose 13, the first arc pressure ring 121 and second
122 inner wall of arc pressure ring is equipped with the groove 112 for 111 insertion of protrusion, when the first arc pressure ring 121 and the second arc pressure ring
122 to when the movement of 11 direction of casing, and protrusion 111 slowly enters in groove 112, and the deformation of hose 13 at this time also will slowly enter groove
In 112, the connection of hose 13 and casing 11 is strengthened, as long as bolt 124 will be connected when disassembly fixing piece 12 from connecting plate 123
Disassembly, it is easy to operate.
Such as Fig. 3 or fixing piece 12 or the external screw thread that casing 11 and the conflict outer wall of hose 13 are set, casing 11
Outer wall dimension is greater than the inner wall size of hose 13, is tightly connected at this time in 11 outer wall of casing and with 11 outer wall of casing for 13 sets of hose, outside
Screw thread increases frictional force of the hose 13 between casing 11, so that hose 13 is not easy to remove from casing 11, installing and dismounting letter
It is single.
Such as Fig. 4, when backwashing denitrification filter pool 2, in order to reduce the water entered in distributing channel 1 by hose 13, therefore
Hose 13 is equipped with duckbill valve 14 in one end far from casing 11, when denitrification filter pool 2 is backwashed, due to denitrification filter pool
2 liquid levels are higher than liquid level in distributing channel 1, and duckbill valve 14 is in closed state, and backwashing water is discharged by 1 weir crest of distributing channel, avoids filtering
Material loss.Furthermore duckbill valve 14 can also be linked together by above-mentioned fixing piece 12 and hose 13, so that when replacement hose 13
It is individually replaced hose 13, does not need to change duckbill valve 14.
Such as Fig. 5, when another outside water is flowed out from casing 11, the power that water separate 1 direction of distributing channel oriented to casing 11 pushes,
In order to reduce the effect of this part power, and then protection sleeve pipe 11, therefore threaded one end connection of the casing 11 far from hose 13 is limited
Position sleeve 15, spacing collar 15 are equipped with the stop collar 151 contradicted with 1 bottom of distributing channel in the side for stretching out 1 upper end of distributing channel, this
When stop collar 151 limit casing 11 and removed out of distributing channel 1 so that casing 11 is stably fixed in distributing channel 1；Limit sleeve
One end that cylinder 15 is located at casing 11 is equipped with the protection pipe 16 extended into casing 11, and 16 outer wall of protection pipe is supported with 11 inner wall of casing
Touching, protection pipe 16 reduces the contact of water with casing 11 at this time, protects casing 11, will limit when 16 corrosion and damage of protection pipe
Sleeve 15 is screwed out out of casing 11.
Embodiment 2:
To stream denitrification filter pool inlet channel water dispensing apparatus under one kind, difference from example 1 is that, such as Fig. 6 and figure
7, fixing piece 12 includes being provided with the annular fixing groove 125 of casing 11 and the conflict outer wall of hose 13 and being arranged in 13 outer wall of hose
And the band 126 that is embedded in fixing groove 125, one end of band 126 offer several fixation holes 127, the other end is equipped with for hoop
With the fixed ring 128 that 126 one end pass through, fixation hole 127 is uniformly distributed along the length direction of band 126, when one end of band 126
When across fixed ring 128, the check lock lever 129 across fixation hole 127 is threaded in fixed ring 128, the insertion of check lock lever 129 is solid
Determine to limit the movement of band 126 in hole 127, when disassembly removes check lock lever 129 from fixed ring 128, by the one of band 126
End is removed out of fixed ring 128, easy to operate.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
