Sliding type air duct system used for mobile type paint-spraying room waste gas extraction

Abstract

The invention relates to the field of waste gas treatment systems, and discloses a sliding type air duct system used for mobile type paint-spraying room waste gas extraction, which solves the technical problem that the gas exhaust tube is too long and is orderly dragged on ground as a gas exhaust tube cannot move in a length direction of an air duct. The sliding type air duct system comprises a movable paint-spraying room and the air duct as well as the gas exhaust tube which communicates between the paint-spraying room and the air duct, wherein a through slot is formed in a length direction at one side, towards the paint-spraying room, of the air duct; the two sides, in the length direction, of the through slot are provided with a group of elastic sealing parts; one end, away from the paint-spraying room, of the gas exhaust tube is connected to a connecting housing; the connecting housing extends into the air duct through the through slot, is used for enabling the gas exhaust tube tocommunicate with the air duct; the connecting housing and the air duct are arranged in a sliding mode; and the two sides, in the length direction, of the connecting housing separately abut against theelastic sealing parts. On the premise of guaranteeing sealing property of a slot hole of the through slot, the gas exhaust tube moves in the length direction of the air duct along with movement of the paint-spraying room through the connecting housing, so that the gas exhaust tube does not need to drag on ground.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment systems, in particular to a sliding air duct system for extracting exhaust gas from a mobile paint spraying room. Background technique [0002] The Chinese patent with the notification number CN208810405U discloses an environment-friendly mobile spray booth, including a mobile system. The mobile system includes a mobile room, rails, pulleys and electric control devices. Spraying workbench; there is a pulley at the bottom of the painting room, the pulley is placed in the track, and the electric control device is placed on the outer wall of the spraying room. track moves. [0003] Such as figure 1 , the top of the mobile spray booth 1 is connected with an exhaust pipe 13 for discharging waste gas, and an air duct 3 is set up above the spray booth 1, and the end of the exhaust pipe 13 away from the spray booth 1 is connected with the air duct 3. When personnel perform painting operat...

Problems solved by technology

[0004] However, since the spray booth will slide along the track during the painting process, and the end of the exhaust pipe away from the spray booth is fixedly connected to the air duct, it is necessary to reserve a sufficient length of exhaust pipe to drive the spray booth when it moves. The exhaust pipe is dragged along the ground, causing the ground to be messy; and if the spray booth and the branch pipe are directly connected through an exhaust pipe, and a driving mechanism is set to drive the air pipe to move synchronously with the spray booth in the horizontal direction, there will be The problem of high manufacturing costs
