SU55078A1 - Vertical Annealing Furnace - Google Patents

Description

The invention relates to vertical furnaces for annealing glass and similar products, performed in the form of two vertical shafts, which are used for sequential movement of annealing products in them and which in their upper part are parallelly connected to the hot gas supply channel.

In the proposed furnace, only one of the shafts is provided with a gas outlet channel from the furnace, which has the purpose of preventing outside air from entering into the furnace through open windows for loading and unloading products. To improve the heat exchange conditions in the furnace, a heat-accumulating nozzle in the inlet gas channel was used.

In FIG. 1 shows a longitudinal section of the furnace; FIG. 2 is a section along AA in FIG. one; FIG. 3 is a section through BB in FIG. one; FIG. 4 is a section along the explosive in FIG. 2 and 3.

The proposed vertical kiln is mainly intended for annealing glass products, but it may also be used in other industries of the industry for both annealing and

for other types of heat treatment of products and parts.

In the proposed furnace, the working channel consists of two adjacent vertically located mines / and 2, which in their upper part communicate with each other by a common roof 5, and are separated by a non-heat-conducting wall 4 throughout the rest.

The heat-treated products are moved in the working channel with the help of a chain elevator 5 with mesh bars freely suspended on it or sieves filled with products.

In order to prevent external air from going into the furnace, open windows 7 are used for loading and unloading products, and only one shaft is provided with channels 8 by channels 8.

To improve heat exchange conditions and to level out temperature shocks and oscillations that can occur when the furnace is not properly serviced, in the inlet pipe 9 from the furnace 6, the heat accumulating nozzle formed by the folded brick is placed in the channel 9.

The subject matter of the invention.

Claims (2)

1. A vertical kiln for firing glass and similar products, made in the form of two vertical shafts, in the upper part parallel to the channel connected to the supplying hot gases and moving the annealing products conveyor in them, characterized in that only one of the shafts is provided with the exhaust gases from the furnace in order to prevent outside air from being sucked into the furnace through open windows for loading and unloading products, 2. In the furnace according to claim 1, use a heat-accumulating nozzle in the feed gas channel to improve heat exchange conditions. Shig1 and s to the author's testimony A. A.
