Efficient hot-blast stove for grain dryer

Abstract

The invention discloses an efficient hot-blast stove for a grain dryer. The efficient hot-blast stove for the grain dryer comprises a stove body, wherein a base is arranged at the lower end of the stove body; a feeding funnel is arranged at the upper end of the base and communicates with the inside of the stove body; a first fixing ring, a second fixing ring and a discharging body are successively arranged on the outer side of the stove body from top to bottom in a surrounding manner; a plurality of first discharging openings are formed in the outer side of the discharging body in a surrounding manner; a second seal plate is arranged on the inner side of the second fixing ring; a first seal plate is arranged on the inner side of the discharging body; a plurality of second discharging openings are formed in the outer side of the first seal plate in a surrounding manner; and the first fixing ring is connected with the second seal plate through a plurality of second connecting rods. By the efficient hot-blast stove for the grain dryer, moisture can be quickly removed from the drying device, by setting hot air provided by the hot-blast stove, the heating process of the traditional dryer is omitted, service time is saved, the overall efficiency of the dryer is improved, and grains are dried in such a circulating manner and then are discharged until water of the grains reaches a specified value.

Description

technical field [0001] The invention relates to the technical field of grain hot blast stove equipment, in particular to a high-efficiency hot blast stove used for grain dryers. Background technique [0002] As we all know, when the temperature and humidity conditions in the environment where the food is located meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of microorganisms such as mold in grain. In general, controlling the grain moisture below the safe moisture level may prevent the grain from going moldy. At present, the method for reducing grain moisture is the spontaneous combustion drying method. In the main grain producing areas, due to the large output and insufficient drying space, the moisture in the grain purchased by the grain depot often exceeds the safe water content, which is the main factor causing the grain mildew in the grain depot, especially ...

AI Technical Summary

Problems solved by technology

In the main grain producing areas, due to the large output and insufficient drying space, the moisture in the grain purchased by the grain depot often exceeds the safe water content, which is the main factor causing the grain mildew in the grain depot, especially when the grain purchase period is catching up with the continuous cloudy days, it is even more serious. In this way, in addition, even if the moisture content of the grain does not exceed the safe moisture content when entering the warehouse, due to spontaneous combustion and moisture return, the grain stored in the warehouse needs to be dried regularly to ensure that the grain does not go moldy. The grain is often not dried on time, which causes the grain in the grain depot to become mildewed. Therefore, people use dryers to dry the moisture in the grain. Because the existing grain drying technology is to directly input the hot smoke generated by fuel combustion into the The grain drying layer of the grain dryer, this direct heating method will cause pollution to the grain, and at the same time, the temperature of the hot smoke generated by fuel combustion cannot be controlled, and the excessive temperature will cause the grain to burst
