Background

Septic tank, sewage case, rainwater collecting box can all be divided into the purification groove part of sewage treatment ware, and these all are municipal indispensable equipment. The products of the prior septic tank, the sewage tank and the rainwater collecting tank are mostly formed by splicing two half bodies, are mainly limited by the demoulding of the molding processes such as mould pressing, injection molding and the like, and the two half bodies are assembled into a container by using bolts and sealing strips, which can be seen in the utility model patent of the Chinese patent CN 208747900U. The above prior art has the following disadvantages: the seam is at the maximum outer diameter position and below the working liquid level in the seam, and leakage at the seam position is easily caused due to the influence of stamping stress, pressure and weather temperature difference change in the working process, so that the service life of a product and a system is influenced, and the environment is polluted.

Disclosure of Invention

The utility model aims at providing a rotational moulding seepage prevention structure's sewage treatment ware purifying trough.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a sewage treatment device purifying tank with a rotational molding anti-seepage structure comprises a tank body, wherein the tank body is formed by connecting a lower container and an upper cover through a fastener, the top of the lower container is open, an upward cover placing surface is arranged on the edge of the opening of the lower container, and a baffle edge which is turned over and extends upwards is arranged on the periphery of the cover placing surface; the lower end of the upper cover is embedded in a circle of flange and is placed on the cover; a sealing ring is arranged between the cover placing surface and the upper cover for sealing connection; in the working state, the working liquid level in the lower container is positioned below the resting surface of the cover.

In the above scheme, the fastening member is a bolt, a plurality of bolt holes are correspondingly arranged on the upper cover and the cover placing surface, and the bolt penetrates through the bolt holes on the upper cover and the cover placing surface and then is connected with the nut.

In the above scheme, the upper opening edge of the lower container extends upwards to form the arch part at two axial ends of the tank body.

Furthermore, the arch parts at the two ends of the lower container are provided with an inlet and an outlet.

In the above scheme, the inner side surface of the flange is also provided with a sealing ring to be connected with the periphery of the upper cover in a sealing way.

Because of the application of the technical scheme, compared with the prior art, the utility model have following advantage and effect: in the embodiment, the tank body is designed to be composed of the lower container and the upper cover, the working liquid is only in the lower container during working, and the working liquid level is lower than the joint of the upper cover and the lower container, so that the liquid in the container is ensured not to leak. And a circle of flanges are designed on the edge of the opening of the lower container, so that the flanges play a role of blocking in case of small amount of leakage, and seepage cannot leak to cause external environmental pollution. Meanwhile, the flanges also shield the sealing rings at the seams from wind and sunlight, so that the corrosion to the sealing rings is reduced, and the service life is prolonged.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b): referring to figures 1-5:

a sewage treatment device purifying tank with a rotational molding anti-seepage structure can be a septic tank, a rainwater collecting box and the like. Of course, when the septic tank is a septic tank, a septic tank partition plate, a septic pipe, etc. are installed therein, and when the septic tank is a rainwater collection tank, a pump valve pipe, etc. are installed therein.

The sewage treatment device purifying tank comprises a tank body 1, wherein the tank body 1 is formed by connecting a lower container 11 and an upper cover 12 through a fastener, the top of the lower container 11 is an open opening 111, an upward cover placing surface 1111 is arranged on the periphery of the open opening 111 of the lower container 11, and a ring of flanges 1112 extending upwards are arranged on the periphery of the cover placing surface 1111.
