Description

There are some varieties of drying ovens in which the flue gases pass through a system of vertical or horizontal channels.

Known furnaces with vertical channels, which are inserted into metal pipes. During these furnaces, water circulates through these pipes and takes away excessive heat from the furnace if the process requires it. Water heated in pipes can be used for various technical purposes.

In the proposed drying oven, in addition to pipes installed in vertical channels, additional horizontal tubular water heating elements are used, located in the bottom channels and designed to regulate the temperature in the furnace by changing the amount of water passed through these elements.

In FIG. 1 is a front view of the furnace; FIG. 2 is a vertical section along the line AB in FIG. 3; FIG. 3 is a horizontal section along the CDEF line of FIG. 2; FIG. 4 view

from the side and FIG. 5 is a vertical section along the line UK in FIG. 3

The proposed drying oven is designed for drying metal products, such as headlights, sirens and other automotive parts.

The walls 14 of the drying oven have vertical channels 2, in which V-shaped metal pipes 3 are located, interconnected by flanges 12 and forming a generally continuous boiler. All pipes 3 of the boiler are combined into two independent sections, into which water is supplied through pipes 5 and 5 and, on leaving the boiler, goes through the common manifold 7 to the main.

Tubular elements 4 are included in each section to regulate the temperature in the firebox in the horizontal bottom channels. By changing the amount of water supplied to these elements 4, respectively, a change in the temperature of the furnace 8 is achieved.

The boiler in the proposed drying oven can also be used as a steam steam from a forced circulation boiler, for which you need to install 7 washers with openings for steam separation and an additional pipe loop to the feed pump in the collector.

Sun installation as a whole is enclosed in a metal frame / 5. The doors 10 serve for loading the furnace. The furnace 8 is located at the bottom of the furnace and the furnace doors P are insulated from the loading side.

The subject matter of the invention.

A drying oven with vertical walls of canals, in which pipes of a hot-water boiling boiler are located, characterized by the use of additional horizontal tubular elements 4 located in the bottom channels 1 and designed to control the temperature in the furnace 8 by changing the amount of water flowing through these elements.
