Sieve roller counterflow cooler

Abstract

The invention discloses a sieve roller type countercurrent cooler, which comprises a frame, a collection box, a cooling box body, a feeder, an air outlet top cover, a bulk material device and a material discharge mechanism, and the air outlet top cover is arranged on the cooling box The top of the body, the collecting box is set under the cooling box, the collecting box is set on the frame, the discharge mechanism is set in the collecting box, the feeder, the air outlet cover, and the bulk material are respectively set in the cooling box. Above the box body, it is characterized in that the discharge mechanism includes several horizontally arranged screen-type discharge rollers arranged under the cooling box and a motor device correspondingly connected to the screen-type discharge rollers. The type discharge rollers are parallel to each other, and an interval is set between two adjacent screen type discharge rollers, and an inverted V-shaped material guide plate is arranged above the interval, and there are mesh air holes on the material guide plate. The invention can fully cool the material, has a simple structure, and is convenient for disassembly and maintenance.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a feed cooler. Background technique [0002] The counterflow cooler is currently the most advanced pellet feed cooling technology in the world. It is a new generation of cooling equipment researched and developed, which is mainly used for cooling high-temperature pellet feed after pelleting. Through the reverse movement of the cooling air and the high-temperature and high-humidity materials, the materials are gradually cooled from top to bottom, which avoids the defects of surface cracking of materials caused by sudden cooling in general vertical coolers, and the difficulty of dissipating moisture and heat in the core. The cooling effect is excellent. It is superior to existing domestic similar products. The temperature of the cooled material is not higher than the outside temperature + 5°C, and the precipitation rate is not lower than 3.8%, which plays a good role in producing ...

AI Technical Summary

Problems solved by technology

Although the cooling effect of the cooler is remarkable, it still has certain defects: 1. The cooling box is made of octagon, so the material is not cooled uniformly and the material is arched; 2. The discharge mechanism adopts the impeller type discharge roller, and the bottom of the impeller Airtight, resulting in a dead angle, resulting in a slightly faster discharge time, or a little more particles into the cooling chamber, the cooler discharge is still hot, unable to improve the cooling efficiency; 3, the multi-row discharge roller is made of double chain Transmission, after a period of use, it is necessary to manually adjust the chain tightness, which is troublesome to operate
