Abstract

The invention provides a vertical cement clinker cooling machine, and belongs to a solid material cooler. The vertical cement clinker cooling machine comprises a cylinder body, wherein the cylinder body consists of an upper vertical cylinder and a lower vertical cylinder which are in tight coupling, a material inlet is connected with the upper part of the upper vertical cylinder, a crushing machine is arranged in the upper vertical cylinder, a discharging machine is arranged in the lower vertical cylinder and is driven by a transmission mechanism, a discharging tube is arranged at the bottom of the lower vertical cylinder, a fixed shaft of the transmission mechanism is a hollow air inlet tube, and the air inlet tube is communicated with the interior of the lower vertical cylinder. The vertical cement clinker cooling machine has high heat exchange efficiency and heat utilization efficiency so that materials and gas exchange heat in a countercurrent flow manner, and the hot solid materials are quickly cooled down. Therefore, the characteristics that the energy consumption and the cost are low are achieved.

Description

technical field [0001] The invention belongs to the field of gas-solid two-phase heat exchange, and relates to a solid material cooling device, in particular to a vertical cement clinker cooling machine. Background technique [0002] The cement clinker cooler is one of the important equipments in the production of cement clinker. It undertakes the functions of rapid cooling, heat recovery and transportation of the high-temperature clinker leaving the rotary kiln. The rapid cooling of cement clinker is beneficial to prevent the growth of the main mineral C3S crystal in the clinker, which is beneficial to increase the early strength of the clinker and improve the grindability of the clinker; at the same time, the liquid phase in the molten state is solidified into a glass body, Most of MgO and C3A are solidified in the glass body, which is beneficial to improve the stability and chemical corrosion resistance of cement clinker; recover a large amount of heat contained in high-t...
