Bucket-type grain elevator with blast heat exchange function

Abstract

The invention relates to a bucket-type grain elevator with a blast heat exchange function. A main air inlet and a main air outlet are distributed on a shell of the elevator, heat exchange gas is introduced into the shell from the main air inlet by a blower, an air inlet partition plate and an air exhaust partition plate are arranged in the shell, secondary air inlets are formed in the air inlet partition plate, air supply nozzles are installed on secondary air outlets, the secondary air outlets are arranged in the air exhaust partition plate, and an air inlet channel is formed between the airinlet partition plate and the side wall of the shell on the side of the main air inlet. An elevating channel is formed between the air inlet partition plate and the air exhaust partition plate, and adescending channel is formed between the air exhaust partition plate and the side wall of the shell on the side of the main air outlet. The food in a hopper completes heat exchange in the elevating channel, and the gas after heat exchange is directly discharged into the atmosphere. In the process of grain lifting and transporting, preheating warming or cooling is synchronously realized, equipmentpurchasing cost and space occupation are saved, and overall operation time and grain damage rate are reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a bucket-type grain elevator with the function of blowing air and exchanging heat. Background technique [0002] Bucket elevators are mainly used for vertical lifting and transportation of powdery, granular or blocky materials. It has the advantages of large conveying capacity, high lifting height and good airtightness. It has been widely used in the grain industry. [0003] At present, in the process of using the traditional bucket elevator to lift and transport grain, the function of the bucket elevator is only to transport the grain from a low place to a high place, and the bucket elevator itself cannot preheat the grain during the transportation process. Heating and cooling, the grain preheating process and cooling process are independent of the lifting and handling process, and independent grain preheating equipment and cooling equipment need to be set up, whi...

Problems solved by technology

[0003] At present, in the process of using the traditional bucket elevator to lift and transport grain, the function of the bucket elevator is only to transport the grain from a low place to a high place, and the bucket elevator itself cannot preheat the grain during the transportation process. Heating and cooling, the grain preheating process and cooling process are independent of the lifting and handling process, and independent grain preheating equipment and cooling equipment need to be set up, which will inevitably require more equipment purchase costs. The heating equipment and cooling equipment will also take up additional space, and the preheating and cooling process independent of the lifting and handling process will also lead to the extension of the overall operation time, and the grain damage rate under multiple processes will be further increased.
