Cooling and drying integrated machine of riding belt

Abstract

The invention provides a cooling and drying integrated machine of a riding belt, and the machine is used for overcoming the defects in the prior art. The cooling and drying integrated machine comprises a cooling chute, a drying chute and a cooling device, wherein the cooling chute is a blanking channel defined by an upper panel, a lower panel, a left panel and a right panel of the cooling chute; the drying chute is a blanking channel defined by an upper panel, a lower panel, a left panel and a right panel of the drying chute; the upper and lower panels of the cooling chute, and the upper and lower panels of the drying chute are provided with non-material-leaking air vents; the feeding end of the cooling chute is located below a kiln head cover of a rotary kiln; the upper panel of the cooling chute is located below the lower panel of the drying chute; and the cooling device is used for supplying cold air to the interior of the cooling chute through the lower panel of the cooling chute. The cooling and drying integrated machine of the riding belt has two functions of cooling and drying, utilizes hot waste gas generated by material cooling treatment to carry out drying treatment on wet materials, and can be used for greatly reducing the consumption of energy sources.

Description

technical field [0001] The invention belongs to the technical field of cement building materials, and in particular relates to a belt-riding cooling and drying integrated machine with both cooling and drying functions. Background technique [0002] In the production process of metallurgical chemical industry and cement building materials, it is generally inevitable to involve the step of drying the production raw materials, so that the water content of the production raw materials meets the requirements of the production process technical standards before they can be put into the next step of production. It is the basic premise of producing qualified products. Also in the production process of metallurgy, chemical industry and cement building materials, the calcined materials need to be cooled by a cooler to reach the temperature allowed by the subsequent transportation, storage and grinding processes to ensure normal continuous production. In the above two heat exchange st...

Problems solved by technology

Among them, the hot exhaust gas generated after cooling the materials will be directly discharged into the atmosphere after treatment, resulting in a waste of heat energy. Even if the hot exhaust gas is used for power generation, the power generation efficiency is very limited; among them, the drying treatment of the materials is generally carried out with a hot blast furnace. The hot air generated is used to dry the materials, and when the hot blast stove is working, it will consume a lot of electric energy and heat energy

It can be seen that in the above two heat exchange steps, the cooling treatment wastes the generated hot exhaust gas, and the drying treatment consumes a large amount of electric energy and heat energy in order to generate hot air, all of which result in a waste of energy.
