Abstract

The utility model relates to a fume extractor in drying room on a hull painting flowline, belonging to a drying technical field, which comprises a rain screen, a fume exhaust pipe, a smoke extractor exhaust fan air valve, a fume exhaust case, a fume exhaust hole and an oil drain; wherein, the drying room is provided with the fume exhaust hole and the oil drain on the top, the fume exhaust case is arranged on the top of the drying room and is covered on the fume exhaust hole and is characterized in that the fume exhaust case is connected with the air valve, air valve is connected with the smoke extractor exhaust fan, the smoke extractor exhaust fan is connected with the fume exhaust pipe and the fume exhaust pipe is connected with the rain screen. A top face of the fume exhaust case is designed slantwise, the oil drain is positioned in the fume exhaust case for discharging oil and water vapor mixture out of the drying room and an axle center of the fume exhaust pipe is not designed on the same axle line with the axle center of the fume exhaust hole. Thus, the utility model has the advantages that the oil-water mixture condensed in the drying room cannot drop onto workpieces of the drying room, so as to ensure the appearance quality of drying workpieces.

Description

The drying chamber fume extractor

Technical field

The utility model relates to the drying chamber fume extractor on the finishing line, belongs to the drying technology field.

Background technology

At present, the drying chamber fume extractor generally is to establish the row of pressure that passes through that chimney discharges naturally also to be had at the top, owing to have temperature spread in the drying chamber and between outside air, following of meeting under the gravity effect after the profit vapour mixture condensation in the drying chamber flue, drip to and form greasy dirt on the workpiece, be difficult to cleaning, influence application product appearance quality, cause economic loss.

Summary of the invention

The purpose of this utility model provides a kind of drying chamber fume extractor, makes condensed profit vapour mixture, drips less than on the workpiece in the drying chamber, thereby overcomes the deficiencies in the prior art.

The purpose of this utility model is achieved in that this device is by rain cover, smoke exhaust pipe, smoke exhaust fan, air-valve, the smoke evacuation housing, the smoke evacuation hole, drain line is formed, drying chamber top is equipped with smoke evacuation hole and drain line, on the drying chamber top, be equipped with the smoke evacuation housing, and cover on the smoke evacuation hole, it is characterized in that: the smoke evacuation housing links to each other with air-valve, air-valve links to each other with smoke exhaust fan, smoke exhaust fan links to each other with smoke exhaust pipe, smoke exhaust pipe links to each other with rain cover, smoke evacuation housing end face adopts inclined design, be provided with drain line in the smoke evacuation housing condensed profit vapour mixture is discharged to outside the drying chamber, smoke exhaust pipe axle center and the design of smoke evacuation axle center, hole be not on same axis.

Because adopt technique scheme, the advantage and the good effect that are had are: the profit vapour mixture of condensation in the drying chamber, drip less than on the workpiece in the drying chamber, guaranteed the presentation quality of oven dry workpiece.
