Description

Technical Field

[0001] The utility model relates to the technical field of sewage tanks, and more specifically to an expanded-capacity and pressure-reducing double-layer sewage tank. Background Art

[0002] The existing sewage tank is an integral sewage tank. Boiler wastewater and other sewage are collected together into the sewage tank and transported centrally. The transportation frequency is relatively high, and the transported sewage volume is also large. However, in the actual production site, there is only a small amount of sediment at the bottom. The whole-tank water replacement method is too inefficient, and the labor and vehicle costs are also relatively high. In addition, the relatively clean condensate water cannot be recycled; moreover, because the sewage tank is connected to the end of the boiler, when the boiler residual pressure enters the water, it will impact the tank wall. After long-term use, the tank body will leak, and if the exhaust is not timely, deformation, swelling of the tank and other situations will occur.

[0003] Therefore, providing an efficient expanded-capacity and pressure-reducing double-layer sewage tank is an urgent problem to be solved by those skilled in the art.

[0004] Utility Model

[0005] In view of this, the utility model provides an expanded-capacity and pressure-reducing double-layer sewage tank, which improves the collection efficiency of slag-containing waste liquid and realizes the recycling of some relatively clean water.

[0006] In order to achieve the above object, the utility model adopts the following technical solutions:

[0007] An expanded-capacity and pressure-reducing double-layer sewage tank, comprising:

[0008] A tank body, which is divided into an upper and a lower distribution of a clean water tank and a slag-containing waste liquid tank by a partition inside the tank body; the slag-containing waste liquid tank has a liquid inlet.

[0009] A connecting pipe assembly, which includes a clean water output pipe, a slag-containing waste liquid output pipe and a connecting pipe. The clean water output pipe is connected and communicated with the clean water tank; a first valve is installed at the end of the clean water output pipe; the slag-containing waste liquid output pipe is connected and communicated with the slag-containing waste liquid tank; a second valve is installed at the end of the slag-containing waste liquid output pipe; the clean water output pipe and the slag-containing waste liquid output pipe are connected and communicated through the connecting pipe.

[0010] By adopting the above technical solutions, the beneficial effects of the utility model are:

[0011] The tank body is designed as a double layer, separated by a partition and connected through a connecting pipe assembly. After the slag-containing waste liquid tank is full of liquid, it flows to the clean water tank. Due to the sedimentation of the sediment by gravity, the water in the clean water tank will be relatively cleaner, realizing the secondary sedimentation of boiler wastewater. When discharging sewage, only the slag-containing waste liquid in the slag-containing waste liquid tank needs to be pumped out, improving the collection efficiency of the slag-containing waste liquid. The relatively clean water in the clean water tank can be recycled.

[0012] Further, a buffer plate inclined at 45° is fixed on the side wall of the slag-containing waste liquid tank corresponding to the liquid inlet.

[0013] The beneficial effect of adopting the above further technical solution is to shunt and decompress the influent water, and relieve the situation such as puncture leakage caused by the direct impact of the influent water at the end of the boiler on the tank wall.

[0014] Further, a flash tank is installed on the liquid inlet.

[0015] The beneficial effect of adopting the above further technical solution is to reduce the residual pressure at the liquid inlet.

[0016] Further, a manhole is provided at the top of the clean water tank.

[0017] The beneficial effect of adopting the above further technical solution is to facilitate the cleaning and maintenance of the inner wall of the tank.

[0018] Further, liquid level gauges are installed on the side walls of the clean water tank and the slag-containing waste liquid tank.

[0019] The beneficial effect of adopting the above further technical solution is to simultaneously monitor the water volume in the clean water tank and the slag-containing waste liquid tank. Description of the Drawings

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained according to the provided drawings without creative efforts.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Such as Figure 1As shown in the figure, an embodiment of the present utility model discloses an expanded-capacity and pressure-reducing double-layer sewage discharge tank, which includes a tank body 1 and a connecting pipe assembly 2. The tank body 1 is divided into an upper and a lower distributed clean water tank 11 and a slag-containing waste liquid tank 12 by a partition plate 3 inside it. In this embodiment, the tank body 1 is in a cuboid shape, and the partition plate 3 is a steel plate, which is integrally connected with the tank body 1; the slag-containing waste liquid tank 12 has a liquid inlet 121; the connecting pipe assembly 2 includes a clean water output pipe, a slag-containing waste liquid output pipe and a connecting pipe. The clean water output pipe is connected and communicated with the clean water tank 11; a first valve is installed at the end of the clean water output pipe; the slag-containing waste liquid output pipe is connected and communicated with the slag-containing waste liquid tank 12; a second valve is installed at the end of the slag-containing waste liquid output pipe; the clean water output pipe and the slag-containing waste liquid output pipe are connected and communicated through the connecting pipe. The tank body 1 of the present utility model is designed as a double layer, separated by the partition plate 3 and connected through the connecting pipe assembly. After the slag-containing waste liquid tank 12 is full of liquid, it flows into the clean water tank 11. Due to the sedimentation of the gravity sediment, the water in the clean water tank 11 will be relatively cleaner, realizing the secondary sedimentation of the boiler wastewater.

When discharging sewage, after the clean water tank 11 is emptied, the second valve is opened, and the transport vehicle collects the lower slag-containing waste liquid, improving the collection efficiency of the slag-containing waste liquid.

In this embodiment, the buffer plate 4 is a steel plate and is welded to the side wall of the slag-containing waste liquid tank 12.

[0025] In order to further optimize the technical solution of the present utility model, a pressure expander is installed on the liquid inlet 121, which can reduce the residual pressure at the liquid inlet.

[0026] In order to further optimize the technical solution of the present utility model, a manhole 111 is provided at the top of the clean water tank 11 to facilitate the cleaning and maintenance of the inner wall of the tank body 1. In this embodiment, the manhole 111 is square.

[0027] In order to further optimize the technical solution of the present utility model, a liquid level gauge 5 is installed on the side walls of the clean water tank 11 and the slag-containing waste liquid tank 12, which can simultaneously monitor the water volume in the clean water tank 11 and the slag-containing waste liquid tank 12.
