Air channel side assembly apparatus of roasting furnace

Abstract

The invention relates to an air channel side assembly apparatus of a roasting furnace. The apparatus comprises a sidewall board, the inner side of the lower portion of the sidewall board is fixedly connected with a furnace bottom board, and the middle position of the furnace bottom board is provided with a cap board mounting hole; an air channel is arranged below the furnace bottom board and applied to the sidewall board, one side of the air channel away from the sidewall board is provided with an air outlet, and one end of the sidewall board is provided with an air inlet tube connected with the air channel; a combustion valve interface is fixedly embedded in the upper portion of the sidewall board; a slag removal hole door is arranged above the furnace bottom board and positioned at the outer side of the sidewall board; and a thermocouple tube is fixedly embedded on the sidewall board and above the furnace bottom board, and a thermocouple is arranged in the thermocouple tube in a seal manner and penetrates through the thermocouple tube. The air channel side assembly apparatus of the roasting furnace has the advantages of reasonable layout, compact structure and strong structural performance in order to improve the performances of the furnace.

Description

technical field [0001] The invention relates to an air duct side component device of a roasting furnace, and belongs to the technical field of used sand recycling equipment. Background technique [0002] At present, my country has become the largest casting production country in the world. According to statistics, every 1 ton of castings needs to discharge 1 ton of waste sand and add 1 ton of new sand. However, the current situation of foundries in my country is that the discharge of old sand from foundry workshops accounts for 70% of the total discharge of solid waste. Therefore, recycling old sand can not only save precious new sand resources and reduce environmental pollution caused by discarding old sand, but also save costs and reduce the purchase and transportation costs of new sand, which has huge economic and social benefits. Therefore, the recycling of old sand has become an indispensable part of the modern foundry. [0003] There are many ways to regenerate old s...

Problems solved by technology

Among them, the roasting furnace is the main equipment for thermal regeneration, and its structural performance directly affects the quality of regenerated sand. However, the effect of the traditional structure of the roasting furnace is not ideal, and the air duct side component of the roasting furnace is the furnace body of the roasting furnace. It is an important part of the air duct, which is usually used to install the air duct and further protect the side of the furnace body. The structural layout of the air duct side components in the prior art is too simple, and the structural performance is generally poor. Therefore, it is necessary to modify the traditional The air duct side components are improved
