Description

A Y-shaped ventilation tube type grain dryer

technical field

The utility model belongs to the technical field of grain and agricultural machinery, and relates to a Y-shaped ventilation pipe type grain dryer.

Background technique

Since the water content of grain is related to the impact on the storage, transportation and processing of grain, it is necessary to make the grain meet the required water content, especially the newly harvested grain has a high water content, which is very prone to fever, enzyme change, and grain. Before storage and long-distance transportation, it must undergo drying and precipitation treatment, so grain drying equipment is more and more widely used.

At present, fixed-bed vertical grain drying equipment is widely used in the domestic market, that is, the grain enters the machine from the top feeding port, and when the grain in the machine is full, the grain is discharged through the mechanical discharging device and the discharging port at the bottom. During the process of passing through several drying units in the machine, the grain interacts with the drying medium, so that the water content of the grain is gradually reduced. Among them, the forms of drying units are currently generally angular tube type, funnel type and plate mesh type. The angular tube type is the most widely used, mainly used for mixed flow, co-current and counter-current drying processes, and funnel type is mainly used for co-current drying process. , while the expanded mesh type is mainly used in the cross-flow drying process. For the most widely used angular tubular grain dryer, there are mainly the following problems: 1. A certain number of angular ventilation boxes that are not closed below are arranged inside the angular tubular dryer. The biggest problem of this angular tube is that the upper part must be It is designed with sharp corners to make the grain flow smoothly downwards. The disadvantage is that it is easy to hang on the sharp corners when the rope-shaped debris is encountered. As more and more accumulations, it will affect the uniform flow of the grains; 2. Due to the angular tube The sharp corners at the top are in direct contact with the flowing grain, and have the greatest chance of being rubbed. It is easy to wear out first, resulting in air leakage and grain leakage, affecting the service life of the dryer.
