Description

Technical Field

[0001] The utility model relates to a pump station for sewage treatment, in particular to a fully plastic one-step molding integrated pump station. Background Art

[0002] At present, the pump station is an important part of the urban sewage treatment network. Its structure includes a tank body, a tank mouth on the top of the tank body, a tank cover for opening and closing the tank mouth, a sewage inlet arranged on the tank wall of the tank body, a crushing screen machine installed in the sewage inlet, and a sewage pump installed in the tank body. The sewage pump is connected to the sewage outlet on the tank wall through a pipeline. When working, the sewage mixture generated by urban consumption is crushed by the crushing screen machine through the sewage inlet and enters the tank body, and then the crushed sewage mixture is discharged through the sewage outlet by the sewage pump. Among them, with the development of rotational molding manufacturing technology, existing tank bodies are usually manufactured by rotational molding technology, but the shapes of these tank bodies are mostly cylindrical or rectangular, and a number of reinforcing ribs are designed on the outer surface of the tank body to improve the structural strength. However, in actual use, it is found that the crushing screen machine or the discharge Components such as pipes at the sewage outlet are heavy, and these components are independently suspended and installed on the tank wall of the tank body, which will cause a single-point force on the tank wall. The existing tank bodies are all smooth cylindrical or rectangular in shape, and the use height is usually high. Therefore, even with external reinforcement ribs, it is difficult to provide stronger support for the single-point force. Therefore, after long-term use, it often causes partial collapse of the tank wall at this location, which in turn affects the sealing of the sewage inlet or sewage outlet; at the same time, in order to facilitate the entry and exit of personnel for maintenance, an H-shaped ladder must be installed in the tank body, but the ladder needs to be manufactured separately and then installed in the tank body. When the sewage pump and pipelines have been installed in the limited tank space, installing a ladder will complicate the internal structure layout of the tank body, which is not convenient for the installation of the internal structure and also increases the manufacturing cost.

[0028] The tank body 1 is composed of a spherical top shell 11, a plurality of drum-shaped middle shells 12 and a spherical bottom shell 13 which are arranged in sequence from top to bottom. The number of the drum-shaped middle shells 12 can be designed according to the height of the tank body 1. For example, the tank body 1 in this embodiment is provided with two drum-shaped middle shells 12, and the cross-section of the entire tank body 1 is also wavy from top to bottom.

[0029] The outer surfaces of the spherical top shell 11 and the spherical bottom shell 13 are provided with a plurality of lifting holes 19, which can be used to facilitate the lifting of the tank body 1; the outer surface of the spherical top shell 11 is provided with an air inlet pipe 15 and an air outlet pipe 16 connected to the tank body 1; the bottom surface of the spherical bottom shell 13 is provided with densely distributed concave reinforcement grooves 132, so that the tank body 1 can also ensure the structural strength under the weight of the built-in dirt, and the outer surface of the spherical bottom shell 13 is provided with foot fixing holes 131, which are convenient for fixing to the cement base when buried in the ground to prevent tipping.

[0030] The outer surface of the tank body 1 is provided with a plurality of solid vertical ribs 7 evenly distributed around the circumference, and each solid vertical rib extends downward from the top of the spherical top shell 11 through a plurality of drum-shaped middle shells 12 in sequence to the bottom end of the spherical bottom shell 13 .

In this embodiment, two solid annular ribs 8 are provided at the intersection of the two to jointly improve the structural strength, and each solid annular rib 8 intersects with each solid vertical rib 7.

[0032] In particular, the spherical top shell 11, the plurality of drum-shaped middle shells 12, the spherical bottom shell 13, the plurality of solid vertical ribs 7 and the plurality of solid annular ribs 8 are all integrally formed by one-time rotational molding, which is convenient for manufacturing and can ensure the consistency of structural strength.

[0033] The tank body 1 is provided with a sewage inlet and a crushing screen machine 4 installed in the sewage inlet on the tank wall. Specifically, a mounting boss 18 protruding outward in a horizontal cylindrical shape is provided on the outer surface of the drum-shaped middle shell 12, and the sewage inlet is arranged on the cylindrical outer end surface of the mounting boss 18, and a hot-melt integrated mounting flange 5 is provided on the sewage inlet, which can be used for an external sewage inlet pipe.

[0034] The number of the mounting bosses 18 is designed according to the height of the tank body 1 and in combination with actual usage.

[0039] In this way, by designing the ladder through this structure, there is no need to manufacture the ladder separately and then install it in the tank body. Therefore, it has the advantages of saving internal space of the tank body, simplifying the internal structure layout of the tank body, facilitating installation and reducing manufacturing costs. In particular, the installation of the ladder rod can also play a role in supporting the inside of the tank body, and further enhances the structural strength of the tank body.

[0040] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
