Description

Technical Field

[0001] The utility model relates to the technical field of sewage lifting equipment, in particular to an integrated sewage lifting equipment. Background Art

[0002] The integrated prefabricated pump station commonly seen on the market is an underground integrated equipment used to lift sewage, rainwater and wastewater. The main structure is a cylindrical barrel (for example, CN 110565789 A), and the outer shell is mostly made of fiberglass. A manual grille (or electric crushing grille), sewage lifting pump, pipe valve, ladder, grille maintenance platform, etc. are installed inside, and a barrel cover and an electric control cabinet are installed outside.

[0003] The biggest difficulty of common integrated prefabricated pump stations when used for sewage pretreatment and lifting is the slag removal problem. Due to the structure of the equipment itself, when sewage enters the pump station barrel through the buried sewage pipe, the slag in the sewage can only be intercepted by a small manual screen (or electric crushing screen). When using a manual screen, the slag box will be filled with slag quickly, and it needs to be manually lifted to the outside of the barrel, and then manually removed from the slag box. When manually pulling up the slag box, there is inevitably a safety risk of working on the edge. When the manual slag removal is not timely, the slag will be washed into the pump station by the water from the larger gap in the slag box, which can easily cause the lifting pump to be blocked.

[0004] When using an electric crushing screen, although most of the soft impurities will be crushed, the crushed granular residue will still block the lift pump or enter the subsequent sewage treatment facilities, causing cumulative pollution blockage to subsequent equipment. Once encountering hard residue, the blades of the crushing screen are easily damaged, and because the screen is installed deep below the ground (usually the lowest point of the sewage pipe network in the area), it brings great difficulties to equipment maintenance.

[0005] Since the above-mentioned two types of grilles have their own problems, it is very easy for debris to accumulate in the barrel of a conventional integrated pump station, and ultimately manual cleaning is required. The cleaning operation will inevitably involve dangerous operations such as climbing, temporary use of electricity, and toxic and harmful spaces, which poses certain risks to the personal safety and occupational health of the operation and maintenance personnel.

[0006] In summary, there is a need for an integrated equipment that can effectively and automatically separate and transport slag and ensure that the lifting pump is not easily blocked by dirt, so as to significantly reduce the consumption of operation and maintenance manpower and reduce operational safety risks. Utility Model Content

[0007] In view of the technical difficulties in the above-mentioned prior art of clothing washing wastewater treatment, the purpose of the utility model is to provide an integrated sewage lifting equipment, which can effectively and automatically separate and transport slag, and ensure that the lifting pump is not easily blocked by dirt, so as to greatly reduce the consumption of operation and maintenance manpower and reduce the safety risks of operations.

[0008] To achieve the above-mentioned purpose and other related purposes, the utility model provides an integrated sewage lifting equipment, including an equipment main body, on which a water inlet and a water outlet are respectively provided; including a water-blocking baffle, a water flow trough is formed between the water-blocking baffle and the side wall of the main equipment; including a rotary screen machine, a part of which is arranged in the water flow trough, and the bottom of the rotary screen machine is connected to the water inlet; a slag discharge port is provided on the top of the rotary screen machine, the opening of the slag discharge port faces downward, a slag receiving box is provided at the bottom of the slag discharge port, and a slag receiving box is also included for receiving slag discharged from the slag discharge port.

[0009] In some embodiments of the present invention, the height of the water-blocking baffle is higher than the height of the water inlet pipe.

[0010] In some embodiments of the present invention, a connecting plate is further included, and the bottom of the rotary grill machine and the water inlet are connected via the connecting plate.

[0011] In some embodiments of the utility model, a maintenance platform is further provided in the main body of the equipment, on which a slide rail is provided, and a lift is also included. The lift can slide toward or away from the rotary screen machine relative to the slide rail, and the slag box is arranged on the lift.

[0012] In some embodiments of the present invention, the size of the slag receiving box is larger than the size of the slag discharge port.

[0013] In some embodiments of the utility model, a lifting pump group is further included, wherein the lifting pump group is connected to the overflow water tank, and the water outlet is connected to the lifting pump group.

[0014] In some embodiments of the present invention, a maintenance ladder is also provided in the equipment body.

[0015] In some embodiments of the present invention, a device top cover is provided on the device body.

[0016] In some embodiments of the utility model, a side of the water-blocking baffle away from the water flow channel is provided with a plurality of internal reinforcing ribs; and a bottom of the equipment body is provided with a plurality of bottom reinforcing ribs.

[0017] In some embodiments of the present invention, an electric control box is also included, and the electric control box is electrically connected to the rotary grille machine and the elevator respectively.

[0019] The integrated sewage lifting equipment provided by the utility model is a new type of underground automatic slag separation, slag delivery and sewage lifting integrated equipment. Different from the conventional integrated prefabricated pump station, it has obvious advantages in slag interception and cleaning. The bottom of the rotary screen machine is connected to the water inlet. After the water enters, the slag can be separated and lifted by the rotary screen machine, and the slag can be discharged from the slag outlet. Since the rotary screen machine is a slow-running device, its own working state is stable, the slag interception effect is far better than the manual screen and the crushing screen, and it has an automatic slag lifting function, so it can perfectly solve the problem of subsequent equipment being blocked due to too much slag.

In a specific embodiment, the opening of the slag discharge port 21 faces downward, and the slag receiving box 3 is arranged at the bottom of the slag discharge port 21 to receive the slag isolated and lifted out by the rotary screen machine 2.
