Technical Field

[0001] The utility model belongs to the field of septic tanks, and specifically refers to a glass fiber reinforced plastic septic tank capable of graded filtration. Background Art

[0002] Septic tanks are a system that separates toilets from sewage treatment, and is mainly used to collect and treat human excrement. Septic tanks can decompose and separate human excrement, remove wastewater and solid matter, and achieve the effect of purifying water sources. This plays a very important role in reducing environmental burdens, protecting water resources, and improving the ecological environment.

[0003] Most of the existing FRP septic tanks are sealed. Although they can temporarily store feces and avoid odor, they are mostly solid-liquid mixtures. In order to facilitate recycling, solid-liquid separation is still required, and the recycling efficiency is low. Some FRP septic tanks with filtering devices are equipped with stirring devices inside to increase the filtering efficiency. However, the temporary storage time of the septic tank is mostly calculated on a quarterly or yearly basis. The cost of using the stirring device is too high. In addition, when clearing the feces in the FRP septic tank, in order to facilitate cleaning, the feces storage function is mostly suspended, which is inconvenient to use. Utility Model Content

[0004] The technical problems to be solved by the utility model are that solid-liquid separation is impossible, the stirring device is not suitable for long-term use, and feces cannot be stored and cleared at the same time.

A partition is fixedly provided on the upper part of the first filter screen and the second filter screen. The diversion control mechanism is arranged at the upper part of the tank body. The diversion control mechanism includes a first hydraulic cylinder and a second hydraulic cylinder. The upper end of the first hydraulic cylinder is fixedly connected to the upper part of the tank body, the lower part of the first hydraulic cylinder is slidably connected to the tank body and passes through the tank body, the lower end of the first hydraulic cylinder is fixedly provided with a drop hopper, the upper end of the second hydraulic cylinder is fixedly connected to the upper part of the tank body, the lower part of the second hydraulic cylinder is slidably connected to the tank body and passes through the tank body, and the lower end of the second hydraulic cylinder is fixedly provided with a baffle.

[0006] Furthermore, the baffle is configured as an inverted L-shaped structure, and the baffle is slidably connected to the surface of the partition.

[0007] Furthermore, the dropping hopper is configured as a hopper-shaped structure, the lower portion of the dropping hopper is configured as a sloped structure, and the lower end of the side portion of the dropping hopper is slidably connected to the surface of the baffle.

[0008] Furthermore, a sewage inlet pipe is provided at the upper part of the tank body, the sewage inlet pipe is connected through the upper part of the tank body, and the lower opening of the sewage inlet pipe is located directly above the drop hopper.

[0009] Furthermore, the upper left and right sides of the tank body are both set as openings, the first sealing door and the upper left opening of the tank body are rotatably connected by a hinge, and the second sealing door and the upper right opening of the tank body are rotatably connected by a hinge.

[0010] Furthermore, the lower portion of the liquid storage tank is configured as a slope-shaped structure, a sewage pipe is provided at the lower end of the lower side portion of the liquid storage tank, and a valve is provided on the sewage pipe.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. The fiberglass septic tank with graded filtration proposed in this scheme is divided into two areas by using a partition inside the tank, and a filter structure is set under the two areas, and a liquid storage tank is used to temporarily store the filtered liquid, so as to complete liquid-solid separation while temporarily storing feces, and facilitate subsequent classification and recycling.

[0013] 2. The fiberglass septic tank with graded filtration proposed in this scheme can change the height of the partition as needed by sliding a baffle on the side of the partition, so as to facilitate the flow of fecal liquid from above the baffle to the right side of the partition, thereby avoiding the coagulation of feces on the left side of the partition that affects the fecal liquid filtration efficiency.

[0014] 3. The fiberglass septic tank with graded filtration proposed in this scheme is convenient to use because a hopper is set under the sewage inlet pipe and the height of the hopper is controlled. This allows the feces on the left side of the partition to be cleared without affecting the feces storage function of the device. BRIEF DESCRIPTION OF THE DRAWINGS
