Description

Technical Field

[0001] This utility model relates to the field of sewage lifting pump station technology, and in particular to an integrated sewage lifting pump station with automatic flushing. Background Technology

[0002] During the operation of integrated sewage lifting pump stations, the filter screen, as a key component for intercepting fine impurities in sewage, directly affects the pump station's water flow efficiency and equipment safety. Although existing pump stations are equipped with filter screen filtration devices, after long-term use, a large amount of silt, fiber, and other impurities easily adhere to the filter screen surface, causing blockage of the filter pores. This not only increases water flow resistance and reduces sewage lifting efficiency, but may also cause filter screen damage due to excessive negative pressure, leading to a chain reaction of problems such as subsequent pump impeller wear.

[0003] Currently, cleaning filter screens largely relies on manual disassembly and washing. This method requires interrupting pump station operation and is cumbersome and labor-intensive, making it unsuitable for the needs of continuous wastewater treatment. Some pump stations have attempted to use simple flushing devices, but these are mostly unidirectional flushing devices, only removing some surface dust from the filter screen. They have limited effectiveness in cleaning stubborn impurities deep within the filter screen pores and cannot completely solve the clogging problem. In addition, the existing backwashing system lacks an effective liquid level monitoring mechanism for its water supply. The backwashing water tank often experiences a sudden drop in flushing pressure due to insufficient water level, affecting the flushing effect; or excessive water level leads to water waste and even safety hazards such as tank overflow.

[0014] (III) Beneficial Effects

[0015] This utility model provides an integrated sewage lifting pump station with automatic flushing, which has the following beneficial effects:

[0016] 1. This integrated sewage lifting pump station with automatic backwashing, through the setting of the backwashing mechanism, when in use, starts the pump body on one side, and the pump body transports the water source in the backwash water tank through the flow pipe and the diversion pipe to the inside of the atomizing nozzle at the top. The atomizing nozzle uses the top to wash the filter screen body at the bottom, washing off the impurities attached to the surface of the filter screen body. The washed-off impurities are discharged through the sewage outlet set at the bottom, thereby achieving the effect of automatic backwashing of the equipment inside, eliminating the need for manual cleaning, reducing the downtime of the equipment, and enabling it to meet the needs of continuous sewage treatment.

[0017] 2. This integrated sewage lifting pump station with automatic flushing system features a level detection mechanism. During operation, the water level inside the backwash tank continuously decreases. To facilitate timely water replenishment, a level gauge is installed on the top of the backwash tank. This gauge monitors the water level in real time. If the level falls below a preset value, a signal is transmitted to a PLC controller on one side. The PLC controller then activates an alarm light to promptly remind staff to replenish the water, preventing a sudden drop in flushing pressure due to insufficient water level, which could affect the flushing effect.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: an integrated sewage lifting pump station with automatic flushing, including a pump station body 1. A backwashing mechanism 2 is installed on the top of the pump station body 1. By setting the backwashing mechanism 2, the internal of the equipment is automatically backwashed, eliminating the need for manual cleaning and reducing the downtime of the equipment, thus meeting the needs of continuous sewage treatment. A backwashing water tank 3 is connected through the end of the backwashing mechanism 2. A liquid level detection mechanism 4 is installed on the surface of the backwashing water tank 3. By setting the liquid level detection mechanism 4, the flushing pressure of the backwashing water tank 3 is prevented from dropping suddenly due to insufficient water level, which would affect the flushing effect.

[0025] The backwashing mechanism 2 includes an atomizing nozzle 201 that is connected to the top of the pump station body 1. A flow pipe 202 is connected to the top of the atomizing nozzle 201. A pump body 203 is connected to the end of the flow pipe 202. A drain pipe 204 is connected to the input end of the pump body 203.

[0026] The liquid level detection mechanism 4 includes a liquid level gauge 401 installed on the surface of the backwash water tank 3. A PLC controller 402 is electrically connected to one side of the liquid level gauge 401 via a power cord. An alarm light 403 is electrically connected to one side of the PLC controller 402 via a power cord.

[0027] The drain pipe 204 is connected to the inside of the backwash water tank 3. The surface of the backwash water tank 3 is equipped with a water inlet 5, which serves to replenish the water source.

[0028] The backwash water tank 3 has two sliding grooves inside, and a filter screen 6 is slidably connected inside the sliding grooves. The filter screen 6 is used to filter the backwash water source.

[0029] A transparent plate 7 is provided on one side of the backwash water tank 3, and a drain outlet 8 is installed on the other side of the backwash water tank 3. The drain outlet 8 serves to discharge backwash water.

[0030] The pump station body 1 is equipped with a filter screen body 9 inside. The lower surface of the pump station body 1 is provided with a sewage inlet 10 and the upper surface of the pump station body 1 is provided with a sewage outlet 11. The sewage inlet 10 serves to supplement sewage.

[0031] The bottom of the pump station body 1 is provided with a sewage outlet 12, and a valve 13 is installed on the surface of the sewage outlet 12. The valve 13 is used to control the capacity of the sewage outlet 12.

[0032] The bottom of the pump station body 1 is fixedly connected to a support leg 14, and the bottom of the support leg 14 is fixedly connected to a base plate 15. The support leg 14 serves to support the pump station body 1.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, start the pump body 203 on one side. The pump body 203 transports the water source in the backwash water tank 3 through the flow pipe 202 and the diversion pipe 204 to the atomizing nozzle 201 at the top. The atomizing nozzle 201 is used to rinse the filter screen body 9 at the bottom from above, washing off the impurities attached to the surface of the filter screen body 9. The washed-off impurities are discharged through the drain port 12 set at the bottom.

[0035] The second step: During use, the water level inside the backwash tank 3 decreases continuously as the equipment operates. To facilitate timely replenishment of water by staff, a level gauge 401 is installed on the top of the backwash tank 3. The level gauge 401 monitors the water level inside the tank in real time. If the water level falls below the preset value, a signal is transmitted to the PLC controller 402 on one side. The PLC controller 402 then controls the alarm light 403 to issue an alarm, promptly reminding staff to replenish the water.
