Strong dewetting temperature-adjusting type cooling unit

Abstract

The invention discloses a strong dewetting temperature-adjusting type cooling unit in the field of grain and feed machinery, comprising a cooler, a cyclone dust separator, a fan and a heat pipe exchanger, wherein the heat pipe exchanger is provided with a heating medium water heat-releasing section, a hot air heat-releasing section, a fresh air heat-exchanging section and a cooling water heat-absorbing section; the cooler is provided with a middle air pipe region; an outlet of the fresh air heat-exchanging section is respectively connected with a middle air inlet and a lower air inlet; and an outlet of the fan is connected in parallel with an exhaust-valve and a hot air utilization valve which is connected with an inlet of the hot air heat-releasing section. For the cooling unit, in winter, the cooling water heat-absorbing section is closed and the heating medium water heat-releasing section, the hot air heat-releasing section and the fresh air heat-exchanging section are opened, thus the air supplement temperature of the cooler is improved by utilizing the afterheat of hot air and steam condensed water, the dewetting capacity is enhanced and the water content of a finished product is lowered; and in summer, the heating medium water heat-releasing section and the hot air heat-releasing section are closed, the fresh air heat-exchanging section and the cooling water heat-absorbing section are opened, and the temperature of fresh air entering into the cooler is lowered by cooling water, thereby the cooling effect is improved.

Description

technical field [0001] The invention relates to a grain and feed processing machine, in particular to a strong dehumidification and temperature-regulating cooling unit. Background technique [0002] During the processing of grain and feed, high-temperature quenching and tempering or heating and drying are often carried out, and then the materials in the high-temperature state need to be cooled. The current cooling unit includes a cooler, a cyclone dust collector and a fan. The cooler is provided with a hot air outlet and a lower air supply discharge device. The lower air supply discharge device is connected to the outside through the lower air inlet. The air inlet of the cyclone dust collector is connected with the air inlet of the cyclone dust collector. When working, the material enters from the top of the cooler, and after being cooled, it is discharged from the outlet at the bottom. The ambient air enters the cooler from the air supply and discharge device at the bottom...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a cooling unit with strong dehumidification and temperature adjustment to solve the problems in the prior art that the cooler has weak dehumidification ability in winter and poor cooling effect in summer, and waste heat in the hot air discharged from the cooler and steam condensed water is wasted. In winter, the hot air discharged from the cooler and the waste heat of steam condensate are used to improve the dehumidification capacity of the cooler, and the cooling water is used to enhance the cooling effect in summer
