Description
The invention relates to the technical field of environmental protection, particularly to an
efficient sedimentation tank having a flushing apparatus.
Efficient sedimentation tanks are used for phosphorus removal, enhanced primary
sedimentation treatment and advanced treatment in coagulation sedimentation, sludge
concentration treatment and sewage treatment of water supply treatment. After the inclined
pipes/ plates arranged in the upper part of a sedimentation tank being used for a period of time,
the sludge in the sewage will adhere to the inner surface of the inclined pipes/ plates and affect
the sedimentation effect, therefore, the inclined pipes/ plates needs to be flushed at regular
intervals. The traditional method is to lower the water level in a sedimentation tank below the
lower end of the inclined pipes/ plates and then flush it them with high-pressure water. This way
of flushing can easily damage the inclined pipes/ plates and the workload is heavy.
The Chinese Patent REF No. CN208302265U discloses an inclined pipe flushing apparatus
for an efficient sedimentation tank. A main air outlet is provided on the side wall of the central
shaft of the scraper, and a main flushing pipe is arranged below the inclined pipes. One end of
the main flushing pipe is connected to the main air outlet, and the main flushing pipe rotates with
the main shaft of the scraper. The other end of the main flushing pipe is connected to the
sub-main flushing pipes, a main air nozzle is arranged above the main flushing pipe, and the end
of the sub-main flushing pipes is pressed against the inner wall of the tank body by gas pressure
during operation. The flushing apparatus covers a wide area without dead corners, however, the
applicant believes that the main flushing pipe in the flushing apparatus is fixed on the main shaft
of the scraper and continuously rotates with the main shaft; on the one hand, the rotating joint on
the upper part of the main shaft is constantly rotating and generally the flushing cycle of a
sedimentation tank is about one month and the flushing time is about one hour, which will
reduce the service life of the rotary joint; on the other hand, the end of the sub-main flushing
pipes is pressed against the wall of the tank by gas pressure, but when the sedimentation tank is
operating, the main flushing pipe and the sub-main flushing pipes have no gas pressure, therefore, the ends of the sub-main flushing pipes are not in close contact with the tank wall, meanwhile the sub-main flushing pipes continuously rotates in the cantilever state, which easily causes damage to the flushing pipe and imbalance of the scraper, shortening the service life of the flushing apparatus and the scraper.
SUMMARY OF THE INVENTION In view of the above-mentioned disadvantages, the present invention teaches an efficient
sedimentation tank having a flushing apparatus; the flushing apparatus works when needing to

DETAILED DESCRIPTION OF THE INVENTION The following description is merely exemplary in nature and is not intended to limit the disclosure, application, or use. It should be understood that in all the drawings, corresponding reference numerals indicate the same or corresponding parts and features. As shown in FIG. 1, an efficient sedimentation tank having a flushing apparatus according to one embodiment of the present invention comprises a tank body 20, a supply apparatus, a conversion body 11, a guide body 13, a main shaft 21, a central pipe 22 and a flushing pipe assembly. The main shaft 21 is located in the tank body 20. The central pipe 22 is located on the upper part of the main shaft 21 and connected with the main shaft 21; the central pipe 22 is hollow and its side wall is provided with an outlet pipe; the supply apparatus is used to provide the central pipe (22) with flushing gas, flushing liquid or flushing gas-liquid mixture. A fixed disc (10) having a quick-opening bolt (12) is provided at the top of the tank body (20); an annular rail (17) is provided on the side wall of the tank body (20); a movable end of the flushing pipe assembly is located in the annular rail (17); the guide body (13) is fixedly connected to the upper part of the flushing pipe assembly; the conversion body (11) is assembled on the guide body (13) and can move up and down along the guide body (13); and the conversion body (11) can be communicated with a connecting end of the flushing pipe assembly and an outlet pipe.
According to the above embodiment, during operation, the main shaft 21 rotates, thereby
driving the central pipe 22 to rotate. When flushing is required, flushing gas, flushing liquid or flushing gas-liquid mixture provided by the supply apparatus is passed into the central pipe 22.
The conversion body 11 is used to realize function switching, that is, to realize the flushing
function and the non-flushing function. When the flushing function is realized, the conversion
body 11 moves downward along the guide body 13 to communicate with the connecting end and the outlet pipe of the flushing pipe assembly, the flushing pipe assembly and the main shaft
rotating synchronously. When the non-flushing function is realized, the conversion body 11 is
separated from the flushing pipe assembly and the central shaft, moving upward along the guide
body 13 and is connected to the fixed disc 10. At the same time, the flushing pipe assembly is separated from the main shaft and does not rotate. The number of outlet pipes is the same as the
number of flushing main pipes, and ends of each outlet pipe have a side flange 14 which is a
quick flange.
Preferably, the supply apparatus includes a water supply apparatus 3, a blower 5, a mixer 1, a flushing main pipe 6 and a rotary joint 9. The water supply apparatus 3 is connected to the first inlet end of the mixer 1 through a regulating water valve 2, and the blower 5 is connected to the second inlet end of the mixer 1 through the regulating gas valve 4, the outlet end of the mixer 1 is connected to the inlet end of the flushing main pipe 6, and the outlet end of the flushing main pipe 6 is connected to the central pipe 22 through a rotary joint 9. An inclined pipe can be flushed with gas, liquid, or a mixture of gas and liquid. When flushed with gas, the regulating gas valve 4 is opened, and the flushing pipe assembly is filled with gas through the blower 5. When flushed with liquid, the regulating water valve 2 is opened, and the flushing pipe assembly is filled with liquid through the water supply apparatus 3. When flushed with the mixture of gas and liquid, the regulating water valve 2 and the regulating gas valve 4 are opened at the same time. After the gas and liquid are mixed through the mixer 1, the gas-liquid mixture is filled into the flushing pipe assembly.
Preferably, the conversion body 11 comprises a connecting flange 111, a bracket 112 and a
fixed flange 113, wherein the two ends of the bracket 112 perpendicular to each other have a
connecting flange 111 and a fixed flange 113 respectively, wherein the fixed flange 113 is no.1 quick flange with a quick-open hole; the two ends of the connecting flange111 respectively have
no.2 quick flange and no.3 quick flange; the connecting flange 111 is located between the outlet
pipe and the connecting end of the flushing pipe assembly. The fixed flange 113 in the conversion body 11 is used to connect with the fixed disc 10. When the fixed flange 113 and the
fixed disc 10 are connected, the flushing pipe assembly is separated from the central pipe 22 and
is in a non-flushing state. The connecting flange 111 is used to connect the outlet pipe and the
flushing pipe assembly. When the connecting flange 111 is connected with the outlet pipe and the flushing pipe assembly respectively, the flushing pipe assembly is in a flushing state. The
two ends of the connecting flange 111 have a no.2 quick flange and a no.3 quick flange
respectively, the no.2 quick flange is connected to the side flange 14 on the outlet pipe, the no.3
quick flange is connected to the flushing pipe flange 15 on the flushing pipe assembly. Preferably, the flushing pipe assembly includes flushing pipe units, each flushing pipe unit
including a flushing main pipe (19) and flushing branch pipes 16; the flushing branch pipes 16
and the flushing main pipe (19) being fixedly connected, one end of the flushing main pipe (19)
is connected to the annual rail and the other end is at the same elevation with the outlet pipe. The flushing main pipe 19 can move along an annular rail. The annual rail not only plays a guiding role, but also plays a positioning role. When the flushing pipe assembly is in a non-working state, the flushing pipe assembly depends on its moving end to be positioned so that it will not fall. The top of the flushing branch pipe 16 is the outlet end which flushes the sludge on the inclined pipe.
Compared with directly opening holes on the flushing main pipe 19, by providing the flushing
branch pipes 16 in the embodiment, the liquid in the flushing branch pipes 16 is more
concentrated, with stronger flushing force and more conducive to flush the inclined pipe or the inclined plate.
According to the above preferred embodiment, the flushing main pipe 19 is connected to the
fixed disc 10 / the outlet pipe side flange 14 of the central pipe 22 through the conversion body
11, the conversion body 11 is sleeved in the guide body 13; the conversion body 11 and the guide body 13 being a clearance fit, the conversion body 11 can move up and down along the guide
bodyl3. When the sedimentation tank process is operating normally, the fixed flange 113 on the
conversion body 11 and the fixed disc 10 are fixed by the quick-open bolts 12, at this point, the
connecting flange 111 on the conversion body 11 is neither connected to the side flushing pipe flange 14 on the central pipe nor to the flushing pipe flange 15 on the flushing main pipe 19, the
flushing main pipe 19 and the central pipe 22 being in a disengaged state; when the inclined pipe
is flushed and the quick-open bolt 12 is loosened, the conversion body 11 moves downward along the guide body 13 under the force of gravity, and the connecting flange 111 on the
conversion body 11 slides between the side flange 14 on the central pipe 22 and the flushing pipe
flange 15 on the flushing main pipe 19 and is automatically positioned and the three flanges are
tightened separately. At the same time, the conversion body is separated from the fixed disc 10 on the tank body 20, and the flushing main pipe 19 and the central pipe 22 are connected
integrally.
In order to reduce the movement resistance of the flushing main pipe 19 in the annual rail,
preferably, one end of the flushing main pipe 19 is connected to the annual rail through a roller 18, the roller 18 being assembled on the annual rail (17). The frictional resistance during rolling
operation is small. In this preferred embodiment, the roller 18 is assembled to reduce the
movement resistance of the flushing main pipe 19 in the annual rail. The roller 18 is located in
the annual rail 17 and will not move out of the annual rail 17. In order to improve flushing efficiency, preferably, the number of flushing pipe units is 1 to 4.
Setting multiple flushing pipe units to work at the same time can improve flushing efficiency.
More preferably, in the flushing pipe units, the flushing part of the flushing main pipe 19 is arranged horizontally, and the flushing branch pipes 16 are arranged along and above the
flushing part of the flushing main pipe 19. The flushing direction of flushing branch pipes 16 is
from bottom to top.
To further improve the effect of flushing the inclined pipe, preferably, the inclination angle of the flushing branch pipes 16 on the same flushing pipe unit are the same, and the inclination
angle of the flushing branch pipes 16 on different flushing pipe units is different. The flushing
branch pipes 16 with different inclination angles flush the inclined pipes from different angles,
so that the sludge on the inclined pipes can be washed away, reducing the possibility of unclean flushing caused by flushing the inclined pipes at a single inclined angle.
Preferably, when there are at least two flushing pipe units, the inclination angle of the
flushing branch pipes 16 increases or decreases sequentially along the rotation direction. The
inclination angles of flushing branch pipes 16 are different in different flushing pipe units and increase or decrease sequentially along the rotation direction. In this way, when the flushing
branch pipes 16 rotate with the main shaft, they can flush the inclined pipe from different
inclination angles. Preferably, at least the angle between the axis of one set of the flushing branch pipes 16 and the axis of the flushing main pipe 19 is 60°. Preferably, when three flushing
pipe units are provided, the angles between the axis of the flushing branch pipes 16 and the axis
of the flushing main pipe 19 are 90°, 60°, and 45° in sequence. The inclinations angle of the
flushing branch pipes 16 increase or decrease sequentially and flushing directions are varied, so that the sludge is effectively flushed away and sinks to the bottom of the pool.
Preferably, one end of the rotary joint 9 is provided with a no.4 quick-flange 8. The main
shaft 21 is provided with a main shaft flange 7 which is opposite to the no.4 quick-flange 8. The
no.4 quick-flange 8 can be set in different working conditions. When the sedimentation tank process is running normally, the no.4 quick -flange 8 on the rotary joint 9 is separated from the
main shaft flange 7; when the inclined pipe needs to be flushed, the no.4 flange 8 on the rotary
joint 9 is quickly connected to the main shaft flange 7; when the main shaft 21 rotates, one end
of the rotary joint 9 close to the main shaft 21 rotates, and the main flushing pipe on the other end is still in a static state.
After the efficient sedimentation tank has been operating for a period of time, the sludge
between the inclined pipes/the inclined plates is deposited on its surface, which affects the sedimentation effect and cannot guarantee the good operation of the process. The detailed
working process of the efficient sedimentation tank having a flushing apparatus in the above
embodiment is: Step10: Pause the sludge scraper for a while, and connect the rotary joint 9 to the main shaft flange 7 through the no.4 quick flange 8.
Step 20:Loosen the quick-open bolt 12, the conversion body 11 moves downward along the
guide body 13 under the force of gravity and is separated from the fixed disc 10 on the tank body
20.The connecting flange 111 on the conversion body 11 slides between the side flange 14 on the central pipe 22 and the flushing pipe flange 15 on the flushing main pipe 19 and is automatically
positioned; the three flanges are tightened respectively, and at this point, the flushing main pipe
19 and the central pipe 22 are connected integrally.
Step 30:Resume the operation of the sludge scraper. One end of the rotary joint 9 close to the main shaft 21 rotates with the main shaft 21, and the flushing main pipe 6 at the other end is still
in a static state; the flushing main pipe 19 rotates with the main shaft 21 and drives the roller 18
to rotate in the annual rail 17. Step 40:When flushing the inclined pipe with water, the regulating water valve 2 is opened
and the regulating gas valve 4 is closed, and the water supply apparatus 3 is started; the
high-pressure fluid enters the central pipe 22 through the mixer 1, the flushing main pipe 6 and
the rotary joint 9; when flushing the inclined pipe with gas, the regulating gas valve 4 is opened, the regulating water valve 2 is closed, and the blower 5 is started; when flushing the inclined
pipe with gas-liquid mixture, the regulating water valve 2 and regulating gas valve 4 are opened,
the water supply apparatus 3 and the blower 5 are started, and the mixture enters the flushing
main pipe 6 after being mixed by the mixer 1. Step 50: After the fluid in the central pipe 22 flows through each flushing main pipe 19, it is
ejected from each flushing branch pipe 16 to flush the sludge between the inclined pipes/plates.
The flushing branch pipes 16 can be set at different inclination angles, therefore effectively
flushing the inclined pipes/plates in a cycled crossover way, which greatly improves the flushing effect.
Step 60: After the flushing being completed, the water supply apparatus 3/blower 5 and the corresponding valves are closed, the scraper is paused for a while, loosen the no.4 quick flange 8 on the rotary joint 9 is loosened to separate the rotary joint 9 from the main shaft flange 7; the
side flange 14 on the central pipe 22 which are connected to both sides of the flange 111 of the
conversion body 11 and the flushing pipe flange 15 on the flushing main pipe 19 are loosened,
and the conversion body 11 is moved upward along the guide body 13 and is fixed on the fixed disc 10 with the quick-open bolt 12
. Step 70: Restart the sludge scraper. The embodiments of the present invention are only preferred embodiments of the present
invention and are not used to limit the scope of the present patent application. That is, all equivalent changes and modifications made in accordance with the content of the application
scope of the present invention should be regarded as the technical scope of the present invention.
