The utility model mainly aims to provide a dewatering system of a drying room of a paper tube factory, which is used for solving the technical problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the drainage system of the drying room of the paper tube factory comprises four drying rooms, wherein drainage devices are arranged in each drying room, each drainage device comprises a first pipeline, a second pipeline and a third pipeline, one ends of the first pipeline and the second pipeline are connected with a radiator, and the other ends of the first pipeline and the second pipeline are connected with the third pipeline; the third pipeline is provided with a first stop valve and a second stop valve; one end of the third pipeline is connected with a collecting pipeline, and one end of the collecting pipeline is connected with a main drainage pipeline.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: three groups of drainage devices are arranged in each drying room.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: and a drain valve is arranged between the first stop valve and the second stop valve.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: and a third stop valve is arranged at one end of the collecting pipeline, which is close to the main drainage pipeline.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: and a branch pipeline is arranged on the third pipeline, and a bypass stop valve is arranged on the branch pipeline.

The beneficial effects of the utility model are as follows: the utility model is suitable for the drainage system of the drying room in the paper tube factory, and when the drain valve is replaced and the pipeline is leaked for maintenance, only the newly added third stop valve of the collecting pipeline at the front end of the drying room is required to be closed, thereby reducing the maintenance difficulty and the maintenance cost, and avoiding the serious economic loss caused by the shutdown of all drying rooms due to the drainage problem of a single drying room.

Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described with reference to the drawings in the embodiments, however, the following detailed description and the embodiments are only for illustrative purposes and not limiting the utility model.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the present utility model, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.

Referring to fig. 1 to 2 of the drawings, a drainage system of a paper mill drying room in the present embodiment includes four drying rooms 1, each drying room 1 is provided with a drainage device 2, the drainage device 2 includes a first pipeline 20, a second pipeline 21 and a third pipeline 22, one ends of the first pipeline 20 and the second pipeline 21 are connected with a radiator, and the other ends of the first pipeline 20 and the second pipeline 21 are connected with the third pipeline 22; the third pipeline 22 is provided with a first stop valve 220 and a second stop valve 221; one end of the third pipeline 22 is connected with the collecting pipeline 3, and one end of the collecting pipeline 3 is connected with the main drainage pipeline 4.
