An embodiment of the utility model provides a sewage promotes pump station with automatic desilting function, as shown in fig. 1, including cell body 8, trunk line 3, flushing pipe 5 and water pump 7 all set up in cell body 8. The inlet of the main pipeline 3 is connected with the outlet of the water pump 7, and the outlet of the main pipeline 3 is positioned outside the pool body 8. The flushing pipe 5 is connected with a bypass of the main pipe 3, so that an inlet of the flushing pipe 5 is connected with a water pump 7, and an outlet of the flushing pipe 5 is positioned at the bottom of the tank body 8. The flushing pipeline 5 is provided with a flushing valve 4 for controlling whether the water pumped by the water pump 7 flows into the flushing pipeline 5.
In this embodiment, when mud in the cell body reaches and sets for the height value, open the washing valve on the flushing pipe way, the high-pressure rivers that the water pump extracted from the cell body erupt from the export that is located the cell body bottom to the flushing pipe way in, wash bottom of the pool mud, need not artifical desilting, also need not pump station stop motion.
The sewage lifting pump station with the automatic dredging function further comprises a controller 1, a liquid level sensor 9 and a sludge concentration sensor 6, wherein the controller 1 is respectively connected with the liquid level sensor 9, the sludge concentration sensor 6 and a water pump 7. Liquid level sensor 9 and mud concentration sensor 6 all are located cell body 8, and mud concentration sensor 6 sets up in the position that is higher than cell body 8 bottom and predetermines the height. Wherein, the controller 1 can adopt an LSK-1JR control cabinet, the liquid level sensor 9 can adopt an MIK-ZP ultrasonic liquid level meter produced by Hangzhou Mike sensing technology, Inc., and the sludge concentration sensor can adopt an MIK-PSS200 online sludge concentration meter produced by Hangzhou Mike sensing technology, Inc.
In this embodiment, the liquid level sensor 9 is used for detecting the liquid level height in the tank body 8, and when the liquid level height reaches the liquid level preset value, sends a liquid level signal to the controller 1. The sludge concentration sensor 6 is used for detecting the sludge concentration in the tank body 8, and when the sludge concentration reaches a preset concentration value (the sludge height reaches the height of the sludge concentration sensor), a concentration signal is sent to the controller 1. The controller 1 is used for sending a starting signal to the water pump 7 when receiving a liquid level signal sent by the liquid level sensor 9; when a concentration signal sent by the sludge concentration sensor 6 is received, an opening signal is sent to the flushing valve 4; when the concentration signal sent by the sludge concentration sensor 6 is not received, a closing signal is sent to the flushing valve 4; and when the liquid level signal sent by the liquid level sensor 9 is not received, sending a stop signal to the water pump 7. This embodiment is through setting up controller, level sensor and mud concentration sensor, and when mud height reached and washes the setting value (mud concentration sensor's the setting height) in cell body 8, automatic opening flushing valve 4 for the high pressure water of 7 extractions of water pump gets into the pipeline that washes, thereby effectively washes bottom of the pool mud, realizes full automation.
Preferably, the bottom of the tank body 8 is provided with a slope. The bottom of the tank body forms a pit, and sludge is deposited in the pit and is convenient to wash and clean.
Preferably, the flushing pipe 5 comprises a standpipe 51 and an annular pipe 52 connected with each other, and the annular pipe 52 is arranged above the bottom slope of the tank body 8; the outlet of the flushing pipeline is positioned on the annular pipe. Because of the annular pipe on the slope of bottom of the pool, standpipe 51 connects the export of water pump 7 and annular pipe 52, and the high pressure water that extracts water pump 7 introduces annular pipe 52 in, and annular pipe 52 sets up on the bottom slope of cell body 8, arranges all around along the pool wall of cell body, guarantees that the homoenergetic all around of bottom of the pool can be washed.
Preferably, the outlet of the flushing pipe 5 comprises at least one first outlet 53 and at least one second outlet 54, and the first outlet 53 and the second outlet 54 are arranged at intervals. The outlets are distributed on the annular pipe 52 to wash the bottom of the tank, and the spraying angles of the adjacent first outlets and the adjacent second outlets are different, so that the washing range is enlarged, and the washing efficiency is improved.
Preferably, the included angle α 1 between the center line of the first outlet 53 and the horizontal plane is equal to the inclination angle β of the bottom slope of the tank body 8. The water injected from the first outlet 53 flushes the sludge on the slope of the bottom of the tank, pushing the sludge into the sludge pit of the bottom of the tank.
Preferably, an included angle α 2 between the center line of the second outlet 54 and the horizontal plane is 5 to 30 degrees larger than an inclination angle β of the bottom slope of the tank body 8. Considering that the area of the bottom of the tank is large, the first outlet 53 can only flush the sludge around the wall of the tank, but the flushing effect on the sludge in the middle of the tank is poor, and the angle of the second outlet 54 is increased to facilitate flushing the sludge in the tank.
Preferably, a main pipe valve 2 is arranged at the outlet of the main pipe 3. When the liquid level in the tank body 8 reaches a preset liquid level value, the main pipe valve 2 is opened, and the water pump 7 is started to operate to convey water in the tank body 8 to the outside of the tank body through the main pipe. Preferably, the main pipe valve 2 is connected with the controller 1, when the liquid level height in the tank body 8 reaches a liquid level preset value, the liquid level sensor 9 sends a liquid level signal to the controller 1, and the controller 1 sends an instruction to start the water feeding pump 7 and open the main pipe valve 2.
The sewage lifting pump station with the automatic dredging function of the embodiment has the following working process: when the liquid level height in the tank body 8 reaches a liquid level preset value, the liquid level sensor 9 sends a liquid level signal to the controller 1, and the controller 1 sends an instruction to start the water feeding pump 7 and open the main pipe valve 2. When the sludge height is lower than the preset sludge height (the set sludge concentration sensor height H), the flush valve 4 is still in a closed state. When the sludge height reaches the preset sludge height, the sludge concentration sensor 6 sends a sludge signal to the controller 1, the controller 1 sends an instruction to open the flushing valve 4, high-pressure water enters the flushing pipeline 5 and passes through the vertical pipe 51 and the annular pipe 52, and then the sludge at the bottom of the flushing tank is ejected from the first outlet 53 and the second outlet 54. When the sludge height is reduced to a preset flushing stopping value, the controller 1 sends an instruction to the flushing valve 4 to close, and the flushing is stopped. When the liquid level in the tank body 8 drops to a preset shutdown value, the controller 1 sends an instruction to stop the operation of the feed pump 7 and close the main pipe valve 2.
When the liquid level height in the tank body 8 does not reach the liquid level preset value and the sludge height reaches the sludge preset height, the controller 1 sends an instruction to start the water feeding pump 7 and open the flushing valve 4 for flushing.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
