Embodiment 1

[0026] see figure 1 and figure 2 , detailing the structural composition of the smoke outlet for removing pipe welding fumes of the present invention.

[0027] Such as figure 1 and figure 2 As shown, a smoke exhaust outlet for removing welding fumes from pipelines is sleeved on the outer wall of the pipeline 1. The smoke exhaust outlet includes a circular static pressure box 2, a roller 3, and a connecting hose 4. The circular ring The plenum 2 is an annular cavity structure formed by connecting a coaxial inner ring member (not shown) and an outer ring member (not shown), and the roller 3 is arranged on the inner wall of the annular plenum 2, and In contact with the pipeline 1, the roller 3 can drive the circular static pressure tank 2 to move along the axis of the pipeline 1, and the outer ring member is provided with an interface capable of connecting the connecting hose 4, and one end of the connecting hose 4 is connected to the circular ring The annular cavity of the ...

Embodiment 2

[0033] Please continue to refer figure 1 and figure 2 , the embodiment of the present invention provides a method for installing a smoke outlet for removing pipe welding fume, the installation method includes the following steps:

[0034] Step 1: Provide the above-mentioned smoke exhaust port for exhausting pipeline welding fumes for use;

[0035] Step 2: before the welding construction, install the exhaust port for removing the welding fume of the pipeline on the outer wall of the pipeline 1, and move it to the vicinity of the welding area 7;

[0036] Step 3: Connect one end of the connecting hose 4 to the interface on the outer ring member of the annular static pressure box 2, and connect the other end of the connecting hose 4 to one end of the air duct main.

[0037] In order to form a negative pressure environment, effectively inhale welding fumes 8, the other end of the air duct main pipe is communicated with the exhaust fan.

[0038] Of course, in order to further en...

Abstract

The invention provides a fume outlet for discharging welding fume of pipes and a mounting method of the fume outlet, belongs to the technical field of pipe welding, and aims to solve the problem that the welding fume cannot be safely and effectively discharged by a traditional method in narrow operation space with poor ventilating effect. The fume outlet comprises a ring-shaped static pressure case, a roller and a connecting hose, wherein the static pressure case is an annular cavity structure which is formed by connecting an inner ring component and an outer ring component which are arranged coaxially; the roller is arranged on the inner wall of the static pressure case and can drive the static pressure case to move along the axis of a pipe; the outer ring component is provided with a connector which can be connected with a connecting hose; one end of the connecting hose communicates with an annular cavity; and the other end of the connecting hose communicates with a header air pipe. The mounting method comprises the following steps: firstly, mounting the fume outlet on the outer wall of the pipe in a sleeving manner, and transferring the fume outlet to a position nearby a welding region; and secondly, respectively communicating two ends of the connecting hose with the static pressure case and the header air pipe.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a smoke outlet for removing pipeline welding smoke and an installation method thereof. Background technique [0002] When the pipeline is welded, it will produce welding fume that is harmful to human health. If not effectively eliminated, when welders perform welding operations, toxic substances in welding fumes, such as ozone, nitrogen oxides, sulfides, carbon monoxide, etc., will be inhaled into the human body, damaging the human respiratory system and nervous system, and endangering the health of the human body. Welders' health. Especially when welding long-distance underground pipelines such as river-crossing tunnels, due to the narrow welding operation space, traditional exhaust fans cannot be installed and used normally, and the welding operation space is not ventilated. Failure to take effective smoke exhaust measures will endanger the health of welders . [00...
