Technical Field

The utility model belongs to the technical field of grate coolers, and particularly relates to a novel side cooling device for a grate cooler, which has the function of increasing the air receiving area.

Background

The grate cooler is an important host device in the cement production and manufacturing process, and has the main functions of cooling and transporting cement clinker; the high-temperature cement clinker burned in the rotary kiln with a certain thickness is conveyed to a grate plate of a grate cooler, the moving grate plate drives the cement clinker on the grate plate to synchronously move, a cooling device is arranged below the grate plate, cold air provided by the cooling device upwards penetrates through the grate plate and a material layer to take away the heat of the cement clinker, so that the cement clinker is gradually cooled in the process of moving from the beginning to the end of the grate plate, and the clinker can be cooled to about 100 ℃ from 1300 ℃ and 1400 ℃ within a few minutes.

Most of cooling devices of the prior grate cooler are arranged below clinker, the cooling quality of the clinker is mainly determined by the air receiving area of the clinker, the air flow rate, the clinker thickness and the like, when the clinker enters the grate cooler, a grate plate drives the clinker to move forward, an air blower below the grate plate starts to blow cold air into an air chamber, the effective air receiving area of the clinker is only the lower bottom surface, when the clinker thickness is larger, the resistance to the cold air is larger, the inside of the large clinker cannot be cooled, the cooling speed is lower, the clinker is not cooled in time at high temperature, fine clinker particles are adhered to each other to form blocks, and the cooling efficiency is lower.

The patent application No. 202023127170.6 discloses a side blow cooling device of a grate cooler, which comprises a low wall in the grate cooler, a wind collecting box on the outer surface of the low wall, a side blow nozzle and a manual butterfly valve which are symmetrically and fixedly arranged, and a plurality of wind pipes are combined together to form the side cooling device. The device can increase the wind flow and can reduce the red river effect. However, the device blows air out from a plurality of side-blowing nozzles, which causes uneven wind on the lateral surface of the clinker and smaller air output, so that the large clinker can not be cooled in time, and the efficiency is low.

The document of application No. 202022982595.9 discloses a side air inlet channel device with a dustproof function, which comprises a main box body and a filtering device, an air inlet pipe arranged on the main box body, an air outlet pipe far away from the air inlet pipe, and a suction fan and an air inlet valve arranged on the main box body. The device can effectually filter the air, promotes inlet air channel's result of use. However, the structure of the air inlet channel is not changed by the device, so that the wind energy is effectively utilized, for example, the wind flow, the wind receiving area of clinker and the like are not increased, and the filter device is higher in manufacturing cost and lacks of economy.
