Abstract
The utility model relates to a sewage pool sewage pumping system, which comprises a sewage treatment main pipe and a plurality of sewage pools and has the innovation point that the sewage pools are communicated with the sewage treatment main pipe through a centrifugal pump, a buffer tank is also arranged between the centrifugal pump and the sewage pools and is communicated with the sewage pools through a first pipeline, the buffer tank is communicated with the centrifugal pump through a second pipeline, a water outlet of the first pipeline is arranged on the top end of the buffer tank, a water inlet of the second pipeline is arranged at the bottom of the buffer tank, and the top of the buffer tank is also provided with a water supplementing opening. When the sewage pool sewage pumping system is used, the water supplementing opening is used for storing water into the buffer tank, the entering of air into the centrifugal pump caused by reverse flowing of water into the sewage pools when equipment stops working is avoided, and the normal work of the centrifugal pump is ensured.
Description
Technical field
The utility model relates to a kind of cesspool sewage pumping system, particularly a kind of cesspool sewage pumping system of long service life.
Background technique
Chemical enterprise need be delivered to the sewage treatment house steward with the sewage pump of cesspool and concentrate transport process when carrying out sewage treatment.Present pumping system adopts self-priming pump to carry out the pumping of sewage; Need be to the self-priming pump water filling guaranteeing the proper functioning of pump, and the water in the self-priming pump is prone to when quitting work, blow back in the cesspool, cause the self-priming pump can't proper functioning; The idle running phenomenon appears; Usually burn out mechanical seal, need repairing, influence is used normally.
Summary of the invention
The technical problem that the utility model will solve provides a kind of cesspool sewage pumping system of long service life.
For solving the problems of the technologies described above, the technological scheme of the utility model is: a kind of cesspool sewage pumping system, comprise sewage treatment house steward and several cesspools, and its innovative point is: said cesspool is communicated with the sewage treatment house steward through centrifugal pump; Also be provided with a knock out drum between said centrifugal pump and the cesspool; Said knock out drum is communicated with cesspool through first pipeline; Knock out drum is communicated with centrifugal pump through second pipeline; The water outlet of said first pipeline is located at the top of knock out drum, and the water intake of second pipeline is located at the bottom of knock out drum, and the top of said knock out drum also is provided with water supplement port.
Further, the volume of said knock out drum is more than three times of first piping volume.
The advantage of the utility model is: during use, utilize water supplement port that knock out drum is carried out retaining, aqueous reflux is gone into cesspool and is made air get into centrifugal pump when avoiding equipment to quit work, and guarantees that centrifugal pump can proper functioning.
Description of drawings
Accompanying drawing 1 is the utility model cesspool sewage pumping system architecture schematic representation.
Embodiment
Shown in accompanying drawing, comprise sewage treatment house steward 1, cesspool 2, centrifugal pump 3, knock out drum 4, first pipeline 5, second pipeline 6, water supplement port 7.
Above-mentioned each cesspool 2 is communicated with sewage treatment house steward 1 through centrifugal pump 3 respectively, and one-way valve 9 and stop valve 10 are installed between the water outlet of centrifugal pump 3 and the sewage treatment house steward 1.
Be provided with a knock out drum 4 between centrifugal pump 3 and the cesspool 2, this knock out drum 4 is communicated with cesspool 2 through first pipeline 5, and knock out drum 4 is communicated with centrifugal pump 3 through second pipeline 6.Wherein, The volume of knock out drum 4 is more than three times of first pipeline, 5 volumes; The water outlet of first pipeline 5 is located at the top of knock out drum 4, and the water intake of second pipeline 6 is located at the bottom of knock out drum 4, and the top of knock out drum 4 also is provided with the water supplement port 7 of band valve; Water supplement port 7 can insert between one-way valve 9 and the stop valve 10 through the 3rd pipeline 8, also can connect external water source.
During use, open the valve and the stop valve 10 of water supplement port 7, knock out drum 4 is carried out retaining, sewage flows backwards and makes air get into centrifugal pump 3 when avoiding equipment to quit work, and guarantees that centrifugal pump 3 can proper functioning.
