Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment equipment, and specifically relates to an intelligent combined rainwater and sewage pump station with functions of preventing sediment deposition and discharging initial rainwater. Background Art

[0002] The integrated rainwater lifting pump station is an indispensable and important helper in the urban drainage system. Its main function is to provide power for rainwater and accumulated water in urban areas and roads when they pass through the pipes, and to transport rainwater and water supply from the municipal pipe network to the discharge site or treatment site. The integrated rainwater lifting pump station adopts a fully buried installation, which is generally divided into an intermediate pump station and a terminal pump station. Usually, rainwater and sewage rely on the gravity of their own weight to be transported from the pipeline. Due to the influence of terrain or silt, the flow power is insufficient. The setting of an intermediate pump station can provide sufficient conveying power for the flowing water in the pipeline, increase the discharge speed, and ensure the smooth discharge of water in the pipeline. The terminal pump station is set up to allow rainwater and sewage to flow smoothly into the terminal. The power of the unobstructed terminal pump station will be a little greater. At present, the integrated rainwater lifting pump station does not have the function of separating the initial rainwater, but the initial rainwater often contains a lot of sediment and other dirt, and the later rainwater is relatively clean. The mixed discharge of the two is not conducive to the comprehensive management of rainwater. Summary of the invention

[0067] Embodiment 2:

[0068] The other contents of this embodiment are the same as those of the embodiment 1, except that: an intelligent rainwater-sewage combined pump station with anti-sedimentation and initial rainwater discharge further includes a crushing pool 2, which is arranged between the pump station body 1 and the rainwater main inlet pipe 3.

[0078] The side of the guide block 11a facing the partition wall 1a1 is an inclined surface, and the inclined surface of the guide block 11a is inclined from top to bottom and gradually away from the partition wall 1a1. The inclined surface of the guide block 11a is provided with a slide groove 11a1 in the same direction as the inclined surface, and the opening cross-sectional size of the slide groove 11a1 is smaller than its internal cross-sectional size.

[0082] The sealing door 1a3 is provided with a linkage rod 1a32 on one side facing the initial rainwater sedimentation tank inspection channel 1e, and the linkage rod 1a32 passes through the first sliding sleeve 1a22.

The thin sliding rod 1a33 slides with the opening of the chute 11a1, and the sliding ball 1a34 cannot escape from the chute 11a1. The sealing door 1a3 has a sealing edge 1a31 extending outwardly on the side facing away from the initial rainwater sedimentation tank inspection channel 1e. The outer diameter of the sealing edge 1a31 is larger than the inner diameter of the drain 1a2.

[0084] A plurality of low-level water pumps 10 are arranged inside the pump station body 1. The water inlet of the low-level water pump 10 can be connected to the later rainwater pool 101 and the rainwater channel 1a. The water outlet of the low-level water pump 10 is provided with a water pump drainage pipe 10a, and the water pump drainage pipe 10a is connected to the main drainage pipe 7 through.

[0085] Embodiment 4:

[0086] The other contents of this embodiment are the same as those of embodiment 3, except that: Figure 3 And attached Figure 5 As shown, a disc-shaped pipe 12 is provided inside the initial rainwater sedimentation tank 102, and the disc-shaped pipe 12 covers most of the bottom surface of the initial rainwater sedimentation tank 102. The disc-shaped pipe 12 is shaped by a shaping plate 12c, and a plurality of pins 12a are fixed below the disc-shaped pipe 12. The bottom of the pin 12a is pointed, and a water cavity 12a1 is provided inside the pin 12a. A water spray hole 12a2 inclined downward is provided at the bottom of the pin 12a, and the water cavity 12a1 is connected to the internal cavity of the disc-shaped pipe 12. A high-pressure water pipe 12b is connected to the disc-shaped pipe 12, and the water inlet of the high-pressure water pipe 12b can be connected to a submersible pump 8 or a low-level water pump 10 drainage pipe, or can be connected to a high-pressure water system alone. The coil-shaped pipe 12 is arranged horizontally. Since the bottom surface of the initial rainwater sedimentation tank 102 is arranged inclined, the lengths of the pins 12a are different, ensuring that after the coil-shaped pipe 12 drops to a certain height, the bottom ends of the pins 12a contact the bottom surface of the initial rainwater sedimentation tank 102 at the same time.

[0087] A plurality of screws 13 are vertically arranged inside the initial rainwater sedimentation tank 102, and the screws 13 pass through the shaping plate 12c and are threadedly connected thereto.

The motor 15 can be a servo motor, and a reducer is provided at its output end.

[0089] The intelligent combined sewer pumping station with sediment prevention and initial rainwater discharge can be controlled by PLC.

[0090] When in use, rainwater flows into the crushing pool 2 through the rainwater main inlet pipe 3, and then flows into the rainwater channel 1a through the crushing pool outlet pipe 4. In the initial stage, there is no rainwater in the initial rainwater sedimentation tank 102. Under the gravity of the guide block 11a, the push rod 11b, and the frame 11d, the guide block 11a moves down to the lowest point, and the upper limit plate 11b2 contacts the guide barrel 11c. At this time, the guide block 11a pushes the linkage rod 1a32, pushes the sealing door 1a3 out of the water outlet 1a2, and opens the water outlet 1a2. The initial rainwater flows into the initial rainwater sedimentation tank 102 through the water outlet 1a2, so that the internal liquid level rises, and the airbag 11e keeps floating on the rainwater liquid surface. Therefore, the rainwater liquid level increases, and the airbag 11e pushes the guide block 11a upward, thereby pulling the sealing door 1a3. When the lower end limit plate 11b1 contacts the guide barrel 11c, the sealing door 1a3 blocks the water outlet 1a2.

[0091] Afterwards, the liquid level inside the rainwater channel 1a increases, and when it reaches the height of the outlet 1b1, it flows into the later rainwater pool 101, and is then discharged into the annular water pipe 6 by the submersible pump 8, and finally discharged from the main drainage pipe 7.

[0092] After the rain stops, the sludge pump 9 can be turned on to discharge the initial rainwater in the initial rainwater sedimentation tank 102, and the sludge inside can be comprehensively utilized.

[0093] The mud remaining inside the initial rainwater sedimentation tank 102 will solidify and harden after a period of time. At this time, the motor 15 is turned on, and the screw 13 is driven to rotate through the driving rod 15a and the synchronous belt 14, so that the disc tube 12 moves down, and the pin 12a is inserted into the hardened mud block, and then high-pressure water is injected. The high-pressure water is sprayed out through the water spray hole 12a2, causing the hardened mud block to crack and loosen, and finally flows into the mud collecting tank 1021 together with the water, and then discharged by the mud pump 9.

[0094] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
