Multi-tube combined type spiral cooler

Abstract

The invention discloses a multi-tube combined type spiral cooler. Vertical type tubular spiral cooling units of a plurality of independent units are combined together to form a combined part. Each independent unit comprises a tubular outer shell. One end of each outer shell is provided with a feed port used for feeding high-temperature powdery materials, and the other end of each outer shell is provided with a discharge port used for discharging the materials. The peripheral side of the portion, between the feed port and the corresponding discharge port, of each outer shell is provided with a cooling water jacket. One end of each cooling water jacket is provided with a water inlet used for injecting cooling water into the corresponding cooling water jacket, and the other end of each cooling water jacket is provided with a water outlet used for draining the cooling water. A main shaft is arranged in each outer shell and fixed to the corresponding outer shell through bearings of the two ends of the main shaft and accessories of the bearings to form a shafting part which can rotate, and each shafting part is provided with spiral blades. The end of each outer shell is provided with a power device. The combined part is provided with a feed hopper which is connected with the feed ports of all the independent units and used for distributing the high-temperature powdery materials. The combined part is provided with a discharge hopper which is connected with the discharge ports of all the independent units and used for collecting and discharging the materials.

Description

technical field [0001] The invention relates to the technical field of powder cooling, in particular to a multi-tube combined spiral cooler. Background technique [0002] In the prior art, the cooling of powdery materials is mainly vertical spiral cooler, chute cooler, composite cooler, etc., and the cooling of bulk materials is mainly single-tube cooler, multi-tube cooler, grate cooler, etc. cooler etc. [0003] Please refer to "1.1 Vertical Spiral Cooler" in the paper "Energy Efficiency Analysis and Comparison of Several Cement Cooling Methods" in the journal "Sichuan Cement" with the classification number of CLC: TQ172.622.4, No. 4, 2008, page 8 "And "1.2 chute cooler", etc. [0004] You can also refer to the invention patent "air cooler" with the application number CN201310122101 and the publication (announcement) number CN103225959A, and the invention patent "composite cooling powder cooler" with the application number CN201320670900 and the publication (announcem...

AI Technical Summary

Problems solved by technology

On the one hand, the contact time between the heat pipe and the material is too short, the heat transfer is insufficient, and the heat transfer effect is poor

On the other hand, the heat pipe is in direct contact with the powder material sliding at high speed, so the wear problem is difficult to solve

[0008] The invention patent "an air cooler" with the publication (announcement) number of CN103225959A, and the invention patent "composite cooling powder cooler" with the publication (announcement) number of CN203561231U, are due to the high height, large volume, powder material Difficult to spread out completely, the cooling effect is limited, which affects the development and promotion of technology to a certain extent
