At the bottom of the drying chamber 30, a conveyor conveying apparatus 33 is installed to convey the painted product 34 along the longitudinal direction of the drying chamber 30, and these products 34 are provided from the conveyor conveying apparatus 33. It is configured to be carried on the product support rod 39 and the product carrier (35, product support) soared at regular intervals in the vertical direction.

When the coated products 34 pass through the inside of the drying chamber 30 by the conveyor conveying device 33, the hot dry air flows into the drying chamber 30 from the hot air supply duct 31. The coated surface of the product 34 is dried by the dry air, and the hot air used for drying is to repeat the circulation process discharged to the outside through the hot air exhaust duct 32, the product 34 is drying chamber 30 After passing through), the painted surface is completely dried to get the final product.

However, according to the conventional hot air drying equipment described above, there are the following problems.

The conveyor conveying device 33 is provided with a guide rail 36, a roller 37, a rotary bearing 38, etc., so that lubricants, such as grease, are supplied to the friction part of these members to prevent wear. Since the apparatus 33 is installed to be exposed in the drying chamber 30 as it is, the lubricating oil is deteriorated by hot air or the bearing parts are deteriorated, thereby reducing the service life and increasing maintenance costs. Due to the supplied hot air, foreign substances or lubricants settled on the floor by guide rails or drying, or their dry matters may scatter and stick to the surface of the product 34, thereby degrading the quality of the coated product 34. On the other hand, since the conveyor conveying apparatus 33 is exposed to high temperature and receives heat, energy loss and temperature of the workplace due to heating to an unnecessary part are caused. It becomes the factor which hinders the working environment.

Therefore, the present invention has been proposed in view of the above point, and its purpose is to prevent aging and heat loss of the conveyor conveying apparatus running in the drying chamber to dry the coated product, and to prevent contaminants scattered from the bottom of the drying chamber. It is to provide a hot air drying equipment of the coating product to prevent the painting product is contaminated.

Hereinafter, with reference to the accompanying drawings, the configuration of the subject innovation will be described in detail.

1 is a view showing a hot air drying equipment of the coating product according to the present invention, Figure 2 is a view showing A-A cross-sectional view of the equipment according to the present invention.

Hot air drying equipment (1) of the present invention is equipped with a drying chamber (2) and a conveyor running room (3) partitioned up and down each other, the multi-layer partition member (4) (4) formed of a heat insulating member conveying apparatus The upper and lower parts are divided horizontally between the 5 and the upper coated product 6.

The multi-layer partition member 4 and 4 has a slit portion 7 which is continuously formed along the conveying direction of the product at the center thereof, and is divided into two sides by the slit portion 7 to form a left and right multilayer layer, respectively. The bulkhead members 4 and 4 are formed.

The conveyor conveying apparatus 5 includes a guide rail 8, a roller 9 and a bearing 10 device which rolls along the guide rail 8, and the conveyor conveying apparatus 5, and the like. The product support bars 11 are protruded vertically at regular intervals.

The product supporting rod 11 protrudes to the upper drying chamber 2 through the slit 10 to support and transport the coated product 6.

Accordingly, when the conveyor conveying apparatus 5 is driven, the product support rod 11 passes along the slit portion 7 which is a space.

A gap adjusting device 12 is provided at the end portions of the multi-layered partition wall members 4 and 4 on both sides in contact with the slit portion 7, and the gap adjusting device 12 has an L-shaped bracket 13 and a L-shaped bracket. The bracket 13 is formed in the width direction (where the width direction refers to the direction perpendicular to the traveling direction) on the bracket 13 and the bracket 13 is formed through the long hole 14 by the multi-layer partition member 4 ( It consists of the bolt fixing means 15 fixed to 4).

Referring to the operation of the present invention as follows.

When the conveyor conveying apparatus 5 is driven, the coated product 6 fixed by the product support bar 11 (or another support shelf may be installed on the support bar) is moved from the inlet side to the outlet side of the drying chamber 2. To be transported.

At this time, hot dry air is supplied from the hot air supply duct 16 into the drying chamber 2 to dry the coated surface of the coated product 6, and the hot air used for drying the coated surface is transferred through the hot air discharge duct 17. It is discharged to the outside.

However, at this time, the hot air hydraulically pressured into the drying chamber 2 is blocked by the multi-layer partition 4 and 4, which is a heat insulation wall, and is prevented from being introduced into the conveyor traveling room 3 having the conveyor transporting device 5.
