Abstract
The utility model provides an underground ventilation pipeline for subway construction, which comprises a three-way pipe and is characterized in that a vent pipe is connected to a right end flange of the three-way pipe, a main filter plate is arranged between the three-way pipe and the vent pipe, a dust collection barrel is connected to a lower end flange of the three-way pipe, a flange pipe is connected to a lower end flange of the dust collection barrel, and a filtering baffle is arranged between the dust collection barrel and the flange pipe. The dust collection tube, the flange tube, the filtering baffle and the conical tube are arranged, so that the convenience degree of cleaning the pipeline is improved.
Description
Technical Field
The utility model belongs to the technical field of mechanical equipment, and particularly relates to an underground ventilation pipeline for subway construction.
Background
At present, when the subway is constructed, the pipeline for ventilation is usually installed in the subway tunnel, and the ventilation pipeline is connected with the ventilation machine in the tunnel, plays the effect of ventilation in the subway tunnel, and this kind of pipeline concatenation head and tail forms, when the pipeline is built-in to attach more dust impurity and influence ventilation, need pull down the pipeline and clear up, and the operation is comparatively complicated.
Disclosure of Invention
In order to solve the technical problems, the utility model provides the underground ventilation pipeline for subway construction, which improves the convenience degree of cleaning the pipeline.
The utility model is realized by the following technical scheme:
the utility model provides a subway construction is with underground ventilation pipe, includes the three-way pipe, its characterized in that, the right-hand member flange joint of three-way pipe has the ventilation pipe, and is provided with main filter between three-way pipe and the ventilation pipe, and the lower extreme flange joint of three-way pipe has a dust collection tube, and the lower extreme flange joint of dust collection tube has the flange pipe, is provided with filtering baffle between dust collection tube and the flange pipe.
Preferably, a conical cylinder is welded to the upper side of the interior of the dust collection cylinder.
Preferably, the left side and the right side of the upper part of the ventilation pipe are respectively welded with a hoisting seat, the front part of the ventilation pipe is glued with a directional sticking strip, and the outside of the ventilation pipe is sleeved with a pipe hoop.
Compared with the prior art, the utility model has the beneficial effects that:
in the utility model, the dust collection cylinder, the flange pipe, the filtering baffle and the conical cylinder are arranged, so that the convenience degree of cleaning the pipeline is improved.
In the utility model, the three-way pipe, the ventilation pipe and the main filter plate are arranged, which is favorable for intercepting larger dust and impurities during ventilation.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic view of the inner structure of the dust collecting cylinder of the present utility model.
In the figure:
1. a three-way pipe; 2. a ventilation pipe; 3. a main filter plate; 4. a dust collection cylinder; 5. a flange pipe; 6. a filtering baffle; 7. a conical cylinder; 8. hoisting the base; 9. directional sticking strips; 10. and (5) a pipe hoop.
Detailed Description
The utility model is specifically described below with reference to the accompanying drawings, as shown in fig. 1, the underground ventilation pipeline for subway construction comprises a three-way pipe 1, wherein the right end flange of the three-way pipe 1 is connected with a ventilation pipe 2, a main filter plate 3 is arranged between the three-way pipe 1 and the ventilation pipe 2, the main filter plate 3 is a stainless steel net plate, the lower end flange of the three-way pipe 1 is connected with a dust collection cylinder 4, the lower end flange of the dust collection cylinder 4 is connected with a flange pipe 5, a filtering baffle 6 is arranged between the dust collection cylinder 4 and the flange pipe 5, the filtering baffle 6 is a stainless steel net plate, and the aperture of the filtering baffle 6 is smaller than that of the main filter plate 3.
In this embodiment, as shown in fig. 2, the conical cylinder 7 is welded on the upper side of the dust collection cylinder 4, and the impurity entering the bottom of the dust collection cylinder 4 returns to the tee 1 by the blowing of wind during ventilation because the upper end opening of the conical cylinder 7 is larger and the lower end opening is smaller.
In this embodiment, specifically, the left and right sides of the upper portion of the ventilation pipe 2 are respectively welded with a lifting seat 8, the front portion of the ventilation pipe 2 is glued with a directional sticking strip 9, and the outside of the ventilation pipe 2 is sleeved with a pipe hoop 10.
Principle of operation
According to the utility model, when the three-way pipe cleaner is in actual use, the main filter plate 3 filters air passing through the three-way pipe 1 and the ventilation pipe 2, large impurities in the air are intercepted in the three-way pipe 1, when the three-way pipe 1 and the ventilation pipe 2 are maintained and cleaned, the impurities enter the dust collection cylinder 4 to be collected, and when the three-way pipe cleaner is cleaned, the externally arranged fan is connected with the flange pipe 5, and the external fan sucks the impurities gathered in the three-way pipe 1 into the dust collection cylinder 4, so that the convenience of cleaning a pipeline is improved.
By using the technical scheme of the utility model or under the inspired by the technical scheme of the utility model, a similar technical scheme is designed by a person skilled in the art, so that the technical effects are achieved, and the technical effects fall into the protection scope of the utility model.
