Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
As shown in figure 1, a rainwater deposits integrative well of filtering, including well body 1 and drainage pipe 2, is equipped with well lid 3 on the well body 1, and drainage pipe 2's exit end intercommunication well body 1 bottom is intake and is held 4, and intake and hold 4 is equipped with first solenoid valve 7, and the top lateral wall of well body 1 still is equipped with drainage end 5, and the bottom of well body 1 still is equipped with blowdown end 6. A filter layer 8 is arranged in the well body 1 and positioned between the drainage end 5 and the water inlet end 4. In addition, the drainage end 5, the water inlet end 4, the filter layer 8 and the sewage discharge end 6 are sequentially arranged from top to bottom in the vertical direction.
The water-saving and water-saving device further comprises a back-flushing pipeline 10, one end of the back-flushing pipeline 10 is communicated with the drainage pipeline 2, the other end of the back-flushing pipeline is communicated with a flushing end 11 of the well body 1, the flushing end 11 is located between the filtering layer 8 and the drainage end 5 in the vertical direction, and a second electromagnetic valve 12 is arranged at the flushing end 11.
Under the normal condition, when the rainwater deposits and filters promptly, close second solenoid valve 12, open first solenoid valve 7, the rainwater passes through drainage pipe 2 and gets into well body 1 through end 4 of intaking in, along with the increase of water yield, the interior water column of well body 1 risees, filters to through filter layer 8, and the water after the filtration passes through filter layer 8 and is discharged by drainage end 5, and filterable filth deposits in well body 1, discharges through blowdown end 6 at last.
Because in daily continuous filtering process, the debris that gather on the filter layer 8 are more, can seriously influence the filter effect of filter layer 8 to the debris that fall into on the filter layer 8 from well body 1 also can gather going equally, for guaranteeing the filter effect of filter layer 8 this moment, back flush channel has still been designed to this application.
In the back flushing state, as shown in fig. 2, the second electromagnetic valve 12 is opened, the first electromagnetic valve 7 is closed, water enters the back flushing pipeline 10 through the water discharge pipeline 2 and enters the well body 1 through the flushing end 11, the filter layer 8 is flushed from top to bottom, the filter layer 8 is flushed, and the flushed water is discharged through the water discharge end 5.
In order to improve the filtering effect, the filtering layer 8 is of a cylindrical structure, and the diameter of the filtering layer 8 is gradually reduced from top to bottom. In this way, the filtering area of the filter layer 8 can be increased, thereby improving the filtering effect.
The sewage discharging end 6 is provided with a third electromagnetic valve 16. When sewage drainage is needed, the third electromagnetic valve 16 is opened, and sewage is precipitated and filtered out.
In addition, set up drainage pipe 2 slope in this application, and drainage pipe 2's diameter from top to bottom reduces gradually. Like this, can not only increase the area of intaking for the speed of intaking, but also can play the effect of buffering at the in-process of intaking to avoid because of the reason that water pressure strikes in the turning, and lead to intaking of intaking end 4 to receive the influence, guarantee the intake velocity of intaking end 4.
After the dirt at the bottom of the well body 1 is precipitated, the precipitate can be cleaned out as soon as possible so as to avoid blocking the sewage discharge end 6 by the precipitate.
In particular, in one possible embodiment, first, the top of the filter layer 8 is connected to the manhole cover 3 by means of a first connecting rod 9. Open well lid 3, accessible head rod 9 takes out filter layer 8 to clear up and change filter layer 8.
Secondly, to the filth that deposits in well body 1 bottom, in this application, filter layer 8 bottom is connected with bottom filter screen 14 through second connecting rod 13. Bottom filter screen 14 can filter the bottom sediment, and when well lid 3 was opened, through second connecting rod 13, bottom filter screen 14 was also taken out, can clear up the sediment on the bottom filter screen 14 this moment.
Specifically, the structure of the bottom screen 14: the bottom screen 14 is a cylindrical structure with an open top at one end and a hollow interior.
The bottom screen 14 comprises a bottom screen 141 connected into an integrated structure and two side screens 142 arranged on the bottom screen 141, the two side screens 142 are combined to form a circular tube type structure, the top height of one side screen 142 is higher than that of the other side screen 142, and the height of the water inlet end 4 is arranged between the two side screens 142. Such high setting can guarantee the normal intaking of intaking end 4, and does not receive bottom filter screen 14's influence, but also can guarantee to filter the in-process that deposits at filter layer 8, carries out the secondary with its filth that deposits and filters.
One end of the bottom filter screen 14 is provided with a sewage outlet 15, the sewage outlet 15 corresponds to the sewage discharge end 6 in the horizontal direction, and the sewage outlet 15 is arranged on the side screen 142 with low height.
The bottom filter screen 14 works, and under the normal precipitation and filtration state, the state of the bottom filter screen 14 is as shown in figure 1, and at the moment, the drainage channel is combined with the well body 1 to normally realize precipitation and filtration; in the back flush condition, the bottom screen 14 is in the condition shown in fig. 2, and the dirt outlet 15 is in communication with the dirt discharge end 6 to flush dirt directly from the drain end 5.
Since the bottom screen 14 needs to be rotated to realize the rotation of the manhole cover 3 when the state shown in fig. 1 is changed to the state shown in fig. 2, an indicator 17 is provided on the top of the manhole cover 3, and the indicator 17 corresponds to the sewage outlet 15 in the vertical direction. Therefore, after the indicator 17 is rotated to a preset position, the sewage outlet 15 is rotated to be communicated with the sewage discharging end 6, and the operation is convenient.
The specific implementation principle of the utility model is as follows: when the device works, rainwater enters the well body 1 through the drainage channel, then is precipitated and filtered through the filter layer 8, finally, the precipitated and filtered water is discharged from the drainage end 5, and the precipitate is discharged from the sewage discharge end 6; during backwashing, water enters the well body 1 through the backwashing channel to wash the filter layer 8, and under the combined action of the bottom filter screen 14, the sediment at the bottoms of the filter layer 8 and the well body 1 is treated, so that rainwater can be discharged as soon as possible, the blockage in the well body 1 can be avoided, and the backwashing device is simple in structure, simple in construction and high in practicability.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
