Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as Figure 1-3 As shown, an air supply mechanism for a combined drying tunnel of a coating line includes an induced draft fan 2 in a horizontally arranged drying tunnel 1, the air inlet of the induced draft fan 2 is connected to the air inlet pipe 3, and the induced draft fan 2 is connected to the air inlet pipe 3. The air outlet of the fan 2 is connected to the air heater 4, and the air inlet pipe 3 penetrates into the inside of the drying tunnel 1 to form a horizontal preheating pipe 5, and the end of the preheating pipe 5 is bent and passes out of the drying tunnel 1 , above the air heater 4 is provided with an air filter mechanism 6 for filtering the heated air. The air filter mechanism 6 plays the role of filtering the particles in the hot air. In the prior art, an asbestos net resistant to a temperature above 100° C...

Abstract

The invention belongs to the technical field of coating, and particularly relates to an air supply mechanism for a coating line combined drying tunnel. The air supply mechanism comprises an induced draught fan horizontally arranged in the drying tunnel. An air inlet of the induced draught fan is connected with an air inlet pipe. An air outlet of the induced draught fan is connected with an air heater. The air inlet pipe penetrates into the drying tunnel, and then a horizontal preheating pipe is formed. The end of the preheating pipe is bent and then penetrates out of the drying tunnel. An air filtering mechanism used for filtering heated air is arranged above the air heater. The air supply mechanism can provide purified hot air, the heating speed is high when air is supplied, and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of coating, and relates to an air supply mechanism for a combined drying channel of a coating line. Background technique [0002] In the field of coating technology, the work is generally to spray the object, and then dry and solidify the sprayed object. At present, in the actual coating operation, for the drying step, the primer is cured and then dried with water. The drying process in the prior art is carried out in a rectangular drying tunnel. The workpiece enters from one end of the drying tunnel and is discharged from the other end, forming a continuous feeding and discharging process. During the drying process, how to quickly provide purified hot air is the key to maintaining the drying effect. [0003] Chinese patent literature discloses a combined drying tunnel [application number: 201310370847.4]. The tunnel is composed of a moisture drying device and a curing device. The moisture drying device an...
