Description

Technical Field

[0001] This application relates to the technical field of pipeline drainage, and specifically discloses an automatic drainage device for the aeration pipeline of a biochemical tank. Background Art

[0002] An aeration pipeline is installed at the bottom of the biochemical tank, and a number of aeration discs are installed on the aeration pipeline. Air is blown into the aeration pipeline through the air supply pipe by a Roots blower, and the air blows out from the aeration discs installed on the aeration pipeline to achieve aeration of the sewage in the biochemical tank.

[0003] However, since the air blown out by the Roots blower is at the same temperature as the outside air, and the aeration pipeline is usually located inside the biochemical tank, the air temperature inside the aeration pipeline is affected by the temperature of the sewage in the biochemical tank and is lower than the outside air temperature. Therefore, the air blown into the aeration pipeline is likely to form condensed water inside the aeration pipeline when it gets cold, so it needs to be drained regularly.

[0004] For example, the automatic drainage device for the aeration pipeline of the biochemical tank disclosed in Chinese Patent Publication No. CN216946454U controls the switch of the condensate discharge pipe by a solenoid valve by setting a wind induction head and a time relay. Combining the function of the wind induction head, the wind in the main air supply pipeline is sensed. When it is necessary to drain the condensate, the valve is opened to drain the condensate uniformly. During normal aeration, the condensate is stored in the main air supply pipeline, affecting the aeration effect.

[0005] Therefore, in view of this, the inventor provides an automatic drainage device for the aeration pipeline of a biochemical tank to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to solve the problem that during the aeration process of the traditional aeration pipeline of the biochemical tank, the condensate is always stored in the main air supply pipeline, affecting the aeration effect.

[0007] To achieve the above purpose, the basic scheme of the present utility model provides an automatic drainage device for the aeration pipeline of a biochemical tank, including an aeration pipeline, a number of air supply brackets fixed at the bottom of the biochemical tank and used to support the aeration pipeline, a liquid collection tank arranged on one side inside the biochemical tank, and a drain pipe arranged below the aeration pipeline and communicated with the liquid collection tank at one end. A plug is fixedly connected to the free end of the drain pipe. A number of drainage brackets are also fixedly connected inside the biochemical tank to support the drain pipe and make the height of the drain pipe incline downward towards the liquid collection tank. A number of connecting water pipes are communicated between the aeration pipeline and the drain pipe.

[0008] Further, a one-way valve that can exhaust air outward from the drain pipe is fixedly connected to the plug.

[0009] Further, a number of arc-shaped water guiding parts are opened inside the aeration pipeline, and the top end ports of the connecting water pipes are all communicated into the arc-shaped water guiding parts.

[0010] Further, a baffle is provided at one end of the arc-shaped water guiding part facing the liquid collecting tank.

[0011] Further, a wind guiding plate is fixedly connected to one side of the top end of the baffle facing the arc-shaped water guiding part.

[0012] Further, the thickness of the wind guiding plate gradually decreases from the end connected to the baffle to the free end.

[0013] Further, the connection part of the drain pipe and the liquid collecting tank is located at the top end of the liquid collecting tank.

[0014] The principle and effect of this solution are as follows:

[0015] Compared with the prior art, in the present utility model, the aeration pipe is lifted and an inclined drain pipe is installed below the aeration pipe. During the aeration process in the biochemical tank, the air flow blown into the aeration pipe by the Roots blower will pre-drain the condensed water precipitated into the drain pipe, and the inclined drain pipe will drain it into the liquid collecting tank for storage. Finally, after the aeration of the biochemical tank is completed, the liquid collecting tank is opened to drain the condensed water uniformly, solving the problem that in the traditional biochemical tank aeration pipe during the aeration process, the condensed water is always stored in the main air supply pipe, which affects the aeration effect.

[0020] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the drawings and preferred embodiments, describe in detail the specific embodiments, structures, features and their effects according to the present utility model.

[0021] The reference numerals in the drawings of the specification include: aeration pipe 1, aeration disc 2, first support ring 3, drain pipe 4, liquid collection tank 5, connecting water pipe 6, baffle 7, arc water guide part 8, check valve 9, and air guide plate 10.

[0022] An automatic drainage device for the aeration pipe of a biochemical tank, as shown in the embodiments Figure 1 , Figure 2 and Figure 3 shown:

[0023] It includes an aeration pipe 1, three gas supply brackets installed in the biochemical tank and used to support the aeration pipe 1, a liquid collection tank 5 installed at the bottom right side in the biochemical tank, and an exhaust pipe installed below the aeration pipe 1 and with its right end communicating with the inside of the liquid collection tank 5. A number of aeration discs 2 are equidistantly installed on the aeration pipe 1.

[0024] Specifically, the gas supply bracket includes a first support ring 3 for wrapping and fixing the aeration pipe 1 and first support feet fixedly installed on both sides of the first support ring 3. Three drainage brackets for supporting the drain pipe 4 are also installed in the biochemical tank. The drainage bracket includes a second support ring for wrapping and fixing the drain pipe 4 and second support feet fixedly installed at the bottom of the second support ring. The height of the second support feet in the drainage brackets installed from the left side to the right side of the biochemical tank gradually decreases. Therefore, the left end height of the drain pipe 4 is higher than the right end height of the drain pipe 4. The right end of the drain pipe 4 is also communicated with the top of the liquid collection tank 5.

[0025] In this embodiment, a plug is also fixedly installed at the left end of the drain pipe 4, and a check valve 9 that can only exhaust air out of the drain pipe 4 is installed in the plug.

[0026] A number of connecting water pipes 6 are also installed between the aeration pipe 1 and the drain pipe 4. In this embodiment, the connecting water pipes 6 are installed obliquely towards the liquid collection tank 5.

[0027] A number of arc water guide parts 8 are also opened in the aeration pipe 1. The top end ports of the connecting water pipes 6 are all communicated with the inner side of the arc water guide part 8, and the arc water guide part 8 completely covers the ports of the connecting water pipes 6 and extends upwards to both sides of the aeration pipe 1. And in this embodiment, the connecting water pipes 6 are all installed relative to the position of the aeration discs 2. Baffles 7 are integrally formed at the right end of the arc water guide part 8, and air guide plates 10 are integrally formed at the left side of the top of the baffles 7. The thickness of the air guide plates 10 gradually decreases from the end connected to the baffle 7 to the free end. During the aeration process, the air flow will hit the baffle 7, and accelerate the convergence and precipitation of the condensed water. The precipitated condensed water will flow into the lower arc water guide part 8 or the rear arc water guide part 8, playing a role in guiding the condensed water. At the same time, the air guide plates 10 can play a role in guiding the air flow.

[0028] When the utility model is in use, the air flow blown into the aeration pipe 1 by the Roots blower will pre-drain the separated condensed water into the drain pipe 4, and the inclined drain pipe 4 will drain it into the liquid collection tank 5 for storage. The drain pipe 4 realizes the automatic drainage of the condensed water in the aeration pipe 1 into the liquid collection tank 5 along with the blown air flow. Moreover, the air flow blown into the exhaust pipe 4 can also be discharged through the one-way valve 9. Finally, after the aeration in the biochemical pool is completed, the liquid collection tank 5 is opened to drain the condensed water uniformly.

[0029] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
