A device for drying grain during harvesting using the waste heat of a combine harvester

Abstract

The invention relates to a device for drying grain by combine-harvester waste heat during the harvesting process. The device provided by the invention is arranged on a combine-harvester and comprises a first heat exchanger, a second heat exchanger, a third heat exchanger and a first draught fan, wherein the air outlet of the first draught fan is connected with a grain storage bin of the combine-harvester through a first air supply passage, and the first heat exchanger and the second heat exchanger are disposed in the first air supply passage; the first heat exchanger is connected with a cooling water tank of an internal combustion engine of the combine-harvester; the inlet of the second heat exchanger is connected with an exhaust pipe of the internal combustion engine, and the outlet of the second heat exchanger is connected with the third heat exchanger; and the third exchanger is arranged on the conveyor belt of the combine-harvester.

Description

technical field [0001] The invention relates to a waste heat drying device, in particular to a device which uses the waste heat of a combine harvester to dry grain during harvesting. Background technique [0002] At present, when large-scale grain is received, drying treatment is a difficult problem. First, it requires time management, and second, it requires a lot of energy. According to incomplete statistics, more than 300 million tons of grain mildew and germination are caused by improper grain drying every year. This shows that It is necessary and economical to carry out reasonable drying of grain and use high-tech technology for drying. When drying a large amount of grain on a large scale, a series of drying equipment is required, which not only costs a lot of money when the equipment is introduced, but also consumes time and energy in the later management and maintenance. Moreover, the development and utilization of drying equipment in my country is still at a low leve...

Problems solved by technology

[0002] At present, when large-scale grain is received, drying treatment is a difficult problem. First, it requires time management, and second, it requires a lot of energy. According to incomplete statistics, the grain mold and germination caused by improper grain drying exceeds 300 million tons every year. It can be seen from this Necessity and economy of reasonable grain drying and high-tech drying

When drying a large amount of grain on a large scale, a series of drying equipment is required, which not only costs a lot of money when the equipment is introduced, but also takes time and effort in the later management and maintenance. Moreover, the development and utilization of drying equipment in my country is still at a low level. Foreign countries The technical blockade has also greatly reduced the pace of progress in the development of drying equipment in our country.

At the same time, it is necessary to burn a large amount of coal or consume a huge amount of electricity when drying, resulting in huge energy consumption and environmental pollution
