Description

Technical Field

[0001] The utility model relates to the field of laboratory sewage treatment, in particular to a gas-liquid diversion sewage pipeline. Background Art

[0002] With the development of science and technology, the demand for biochemical laboratories is increasing. However, a lot of pollutants such as experimental waste liquid and waste gas will be generated in the laboratory. If they are discharged at will, it is very easy to cause environmental pollution. Therefore, the laboratory must be equipped with a discharge channel for waste gas and waste liquid. In the existing laboratory, there will be a floor drain connected to the sewage pipe to discharge the waste liquid and treat it uniformly. The waste gas in the laboratory is purified and discharged through the exhaust pipe through the internal filter element. However, this sewage discharge method requires two independent pipelines to discharge the waste gas and waste liquid separately, which is not convenient enough and lacks the means to discharge the waste gas and waste liquid separately. Utility Model Content

[0003] The utility model aims to provide a gas-liquid diversion sewage pipeline to solve the problem that the existing laboratory sewage discharge method requires two independent pipelines to discharge waste gas and waste liquid respectively, which is inconvenient and lacks means for separately discharging waste gas and waste liquid.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A gas-liquid diversion sewage pipeline comprises a gas collecting pipe 1, a liquid collecting pipe 2, an outer ring filter 3 and a central filter 4. The sewage pipeline is fixedly installed at the sewage outlet on the bottom surface of the laboratory. The gas collecting pipe 1 is directly connected to the exhaust fan at the far end to discharge the exhaust gas. The remaining solid waste will be filtered out by the outer ring filter 3 or the central filter 4. The liquid flows into the liquid collecting pipe 2 and is discharged along the inner wall of the liquid collecting pipe 2. The top of the gas collecting pipe 1 is provided with a plurality of small holes to prevent impurities from entering the gas collecting pipe 1 and causing blockage.

[0006] The liquid collecting pipe 2 is L-shaped and has a thick diameter. A curled edge 21 is provided at the edge of the sewage outlet for installation. A filter ring 22 is provided on the inner wall near the curled edge 21 to prevent impurities from entering the pipeline. The filter ring 22 is provided with a plurality of small circular holes in a circular array, which can only allow liquid to flow in and prevent solid impurities from flowing in.

[0007] The main body of the gas collection pipe 1 is L-shaped, with a thin diameter, facing opposite to the liquid collection pipe 2, and passing through the inside of the liquid collection pipe 2. The top of the gas collection pipe 1 is connected to the central filter 4 through a mating connection. The inner circle of the central filter 4 is a plurality of circular holes with small diameters, and the outer circle is provided with a circle of filter 41.

[0008] The outer ring filter 3 can be inserted between the outer ring edge of the central filter 4 and the inner ring edge of the liquid collecting tube 2, and the inner ring edge of the outer ring filter 3 is provided with a small edge protrusion, which can be put on the outer ring edge of the central filter 4 to assist in fixation.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model cleverly combines two L-shaped pipes of different thicknesses, so that waste gas and waste liquid can be separated and discharged from the same sewage outlet. The waste liquid will flow into the liquid collection pipe from the outer circle edge of the sewage outlet and then be connected to the designated position for discharge. The waste gas will be discharged from the laboratory through the gas collection pipe under the action of the exhaust fan connected to the far end of the gas collection pipe.

[0018] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure. Example

[0019] like Figure 1-Figure 4 As shown, a gas-liquid diversion sewage pipeline includes a gas collecting pipe 1, a liquid collecting pipe 2, an outer ring filter 3 and a central filter 4. The sewage pipe is fixedly installed at the sewage outlet on the bottom of the laboratory. The gas collecting pipe 1 is directly connected to the exhaust fan at the far end to discharge the exhaust gas, and the remaining solid waste will be filtered out by the outer ring filter 3 or the central filter 4. The liquid flows into the liquid collecting pipe 2 and is discharged along the inner wall of the liquid collecting pipe 2. The top of the gas collecting pipe 1 is provided with a plurality of small holes to prevent impurities from entering the gas collecting pipe 1 and causing blockage.

[0020] The liquid collecting pipe 2 is L-shaped and has a thick diameter. A curled edge 21 is provided at the edge of the sewage outlet for installation. A filter ring 22 is provided on the inner wall near the curled edge 21 to prevent impurities from entering the pipeline. The filter ring 22 is provided with a plurality of small circular holes in a circular array, which can only allow liquid to flow in and prevent solid impurities from flowing in.

[0021] The main body of the gas collection pipe 1 is L-shaped, with a thin diameter, facing opposite to the liquid collection pipe 2, and passing through the inside of the liquid collection pipe 2. The top of the gas collection pipe 1 is connected to the central filter 4 through a mating connection. The inner circle of the central filter 4 is a plurality of circular holes with small diameters, and the outer circle is provided with a circle of filter 41.

[0022] The outer ring filter 3 can be inserted between the outer ring edge of the central filter 4 and the inner ring edge of the liquid collecting tube 2, and the inner ring edge of the outer ring filter 3 is provided with a small edge protrusion, which can be put on the outer ring edge of the central filter 4 to assist in fixation.

[0023] As a possible implementation, the aperture sizes of the outer filter 3, the central filter 4 and the filter ring 22 of the liquid collection tube 2 can be changed according to actual needs, and fine grids can be arranged on the openings to adjust the filtering effect.

[0024] As a possible implementation, the end of the gas collection pipe 1 may be equipped with an exhaust fan to assist in the discharge of exhaust gas.

[0025] The sewage pipe is installed at the floor drain of the laboratory. The waste liquid in the laboratory will flow into the liquid collection pipe 2 at the edge of the liquid collection pipe 2 and be discharged along the inner wall. Usually, some impurities may be mixed in the waste liquid, so at this time, the outer ring filter 3 and the filter ring 22 of the liquid collection pipe 2 can both play a certain filtering role. Through double protection, the probability of solid impurities flowing into the liquid collection pipe 2 is reduced as much as possible. Once impurities block the outer ring filter 3, as an alternative, a circle of filter 41 provided on the outer ring of the central filter 4 plays a temporary filtering role to further prevent solid impurities from entering the gas collection pipe 1. At the same time, the blockage of the outer ring filter 3 should be checked regularly, and impurities should be cleaned in time. The filter 41 can only play a temporary replacement role.

[0026] As a possible implementation, appropriate waste gas and waste liquid harmless treatment can be set at the ends of the gas collection pipe 1 and the liquid collection pipe 2 to prevent the waste gas and waste liquid from polluting the environment.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
