Specific embodiment
It is a specific embodiment of the invention below, and in conjunction with attached drawing, technical solution of the present invention work is further retouched
It states, however, the present invention is not limited to these examples.
A kind of secondary sedimentation tank, as shown in Figure 1: include pond body 100, be set to 100 bottom of pond body scrape mud component 101,
It is set to the gantry 102 at 100 top of pond body and is set to 100 central axis of pond body, scrapes mud component 101 and gantry for driving
The rotating member 200 of 102 rotations.Under the action of rotating member 200, scrapes mud component 101 and slowly rotated in bottom of pond and scrape mud.
And need to carry out water, mud separation mixed liquor be by a water inlet pipe 105 enter pond body 100 in, the present embodiment
The water outlet of water inlet pipe 105 is set to 100 top of pond body, that is, scrapes the settling zone top where mud component 101, prevents from continuing
The sediment for having completed precipitating is caused to impact into the fluid in pond body 100.In addition, the water outlet of water inlet pipe 105 is equipped with
Through-hole baffle 106, mixed liquor carry out first time water, mud separation under the action of through-hole baffle 106 first, and mud is trapped within through-hole
In baffle 106 and falls under gravity into and scrape mud component 101 and slide bottom of pond with the inclined top of mud component 101 is scraped.
Since the mud of bottom of pond needs to be re-fed into next program reprocessing after collecting, 100 bottom surface of pond body is equipped with sludge out pipe 103,
Simultaneously in order to improve mud extraction efficiency, 100 bottom surface of pond body is formed slopely spoil disposal face to center, and the import of sludge out pipe 103 is set to pond
100 bottom center's minimum point of body.
In addition, the primary water on 100 top of pond body is also required to reprocess after collecting, therefore the top of 100 side wall of pond body is equipped with
It is discharged weir notch 104.
In order to solve the problems, such as that the removal of bottom of pond, the fiber impurity that can not all float to pond face can neither be precipitated to, also
Including the component that flocculates, the air inlet column 310 and air draught part 320 with the driving axis connection of rotating member 200 that flocculation component includes annular,
As shown in Figure 2: air inlet column 310 offers several air inlet ports 311, and the lateral surface of air inlet column 310 passes through connecting rod 312 and pond body
100 inner wall connection；The bottom of 310 lateral surface of air inlet column is equipped with curved baffle 313, and curved baffle 313 is equipped with several through-holes；It inhales
Wind part 320 includes and the L-shaped interconnecting piece 321 of the driving axis connection of rotating member 200 and the fan blade portion connecting with interconnecting piece 321
322, the end abutment of the end in fan blade portion 322 and curved baffle 313.
Under the drive of rotating member 200, air draught part 320 high-speed rotation generates negative pressure so that air from air inlet column 320 into
Stomata road 311 enters sedimentation basin top, and flows through curved baffle 313 under the conveying of air draught part 320, opens up on curved baffle 313
There is the through-hole of diameter very small (diameter is less than 1 millimeter), so that air, which becomes small bubble, pours sedimentation basin top, with
Sewage is formed together bubble.Sedimentation basin top can neither be precipitated down, also not float to the impurity in pond face i.e. in the effect of bubble
Under, it floats upper storage reservoir face and forms dross.
Wherein, air draught part 320 selects mixed flow to make impeller, has the characteristics that flow is big, lift is low, can be defeated within the unit time
Send a greater amount of fluids.
Simultaneously as air draught part 320 needs high-speed rotation, and scrape mud component 101 and the needs of gantry 102 slowly run, because
This rotating member 200 uses high-speed motor, and air draught part 320 is directly connected to 200 drive shaft of rotating member, and scrapes mud component 101 and bridge
Frame 102 passes through the driving axis connection of retarder and rotating member 200 respectively.
In addition, in order to reduce friction when air draught part 320 rotates between air inlet column 310, interconnecting piece 321 and air inlet column
Rubber pad is equipped between 310 medial surfaces.The end in fan blade portion 322 and the end of curved baffle 313 are equipped with rubber pad.
The dross in floating upper storage reservoir face is also salvaged, strikes off processing, therefore connecting rod 312 and 100 inner wall of pond body are led to
Rolling bearing rotation connection is crossed, the medial surface of air inlet column 310 is flexibly connected with interconnecting piece 321 by electromagnet structure.
It when carrying out air draught intake operation, releases and is powered to electromagnet, so that 310 medial surface of air inlet column and interconnecting piece 321
Between be not connected to, the rotation of air draught part 320 not will drive air inlet column 310 and connecting rod 312 and rotate, thus complete air draught into
Gas.It under bubble, after impurity floats to pond face, is powered to electromagnet, to be acted on by magnetic so that 310 inside of air inlet column
Face is connect with interconnecting piece 321, and the rotation of air draught part 320 will drive air inlet column 310 and connecting rod 312 rotates, and connecting rod 312
Rotation can strike off dross.
In addition, connecting rod 312, which is equipped with, removes slag plate 314 in order to further increase its scraping effect to dross, slag plate is removed
314 angles with horizontal plane are 5-30 °.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
