SU503105A1 - Thermoradiation dryer - Google Patents

Description

one

The invention relates to a drying technique, in particular to dryers for long products with a paint coating.

Known thermoradiation dryers with gas heated radiating panels. The panels for more uniform heating in height are made of variable cross-section, decreasing upward, and the fins are fixed on the inner side of the radiating panel.

However, these dryers do not provide uniform heating of the panel with its height more than 1300-2000 mm. In connection with this, lengthy products are transported horizontally through drying chambers, and this increases the length of the equipment of the painting and drying complexes, increases the dimensions of transport devices (overhead conveyors).

Thermoradiation dryers are also known, containing a chamber with vertically installed in it parallel rows of sectional radiating panels with gas heating and an overhead conveyor placed between them, moving long-length dried products in a vertical position along a rail guide. However, in such a dryer, insufficient drying quality is achieved due to uneven heating.

The purpose of the present invention is to improve the quality of drying.

This is achieved by having sections in each

the panels have different heights and are placed in one row in alternating order, and in the opposite panels the joints of the sections are arranged with a shift in the height of the chamber;

the conveyor rail has a wavy shape.

FIG. 1 shows schematically the described dryer, FIG. 2 is a section along A-A in FIG. one.

The dryer contains a chamber 1, vertically mounted in it parallel rows of radiating panels with sections 2, 3, 4, 5, equipped with gas burners 6, and an overhead conveyor located between the panels

a rail 7, having a wavy shape for moving long items 8. Sections 3 and 4 have a greater height compared to the corresponding sections 2 and 5. Their alternate arrangement along

the height of the panels, as well as the wave-like transportation of products 8, smooth out the uneven thermal emission of the upper and lower sections of the panels.
