Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to improve the drying capacity by minimizing the loss of hot air, and at the same time, reduces the occurrence of uneven grain flow, making it easier to obtain more uniformly dried livestock. Not only can it prevent fires caused by grain drying, but it can also change the direction of exhaust air generated during drying work at any time depending on the installation conditions in the workplace. Regarding Kiiso.

Inside the main body of the drying bed, which is an oblong rectangular cylinder long in the front and back direction, a heating tank, a ventilation drying cylinder 11j, and a take-out row are sequentially installed in a three-dimensional KM, running from the upper stage to the lower stage, and inside the ventilation drying cylinder there is a 7615 grains are warmly flowed down by vertically disposing hot air chambers and exhaust air chambers alternately along the direction so that a path is formed in which the lower ends of the hot air chambers and the exhaust gas are connected to each other. Chisa products are dried using hot air.
It is described in Japanese Patent No. 8-36753 and is publicly known.

In addition, when blowing air into hot air rooms via the prefecture (with the same amount of air generated), the larger the number of hot air rooms, the more
It is also clear from physical phenomena that as the number of pulse transmission windows increases, the total area thereof increases, thereby reducing the amount of hot air blowing.

By the way, in the conventional grain dryer of 01, both the hot air chamber and the exhaust chamber are arranged along the front and rear longitudinal direction inside the ventilation drying/carrying barrel, so that the pressure of the accumulated grains is reduced. However, the number cannot be increased for the same grain holding capacity, as this would lead to defects in durability.

Therefore, since the number of hot air chambers and exhaust chambers cannot be increased, the blowing loss of hot air is large, and the drying capacity cannot be improved by using the same amount of hot air.

Not only that, but also the underground passage formed between the heat chamber and the exhaust chamber is formed wide in the front and rear longitudinal direction due to the above structure, which causes a bridging phenomenon in the stored grain and The deposited grains flow down quickly, while the grains deposited on the right sides flow slowly, causing circulation irregularities due to fatal uneven flow, making it impossible to achieve uniform drying of the grains.

In addition, hot air chambers are usually formed by covering the upper and lower parts of the left and right ventilation walls with chevron-shaped plates and the lower part with a flat plate. Some of the dust may pass through the left and right ventilation walls and enter the hot air chamber, accumulate at the bottom, and ignite with the combustion flames that were mistakenly placed inside the hot air chamber, causing a fire accident. many.

In addition, in the above-mentioned known grain dryer, the burner device that generates hot air and the suction/exhaust device that exhausts the dust after drying are installed in the main body of the dryer. R
Since it was fixedly installed in the rear position, the burner device and suction/exhaust device can be simply changed depending on the installation conditions in the workplace. The disadvantage is that the grain dryer cannot be installed.

Therefore, the present invention has been developed to solve the drawbacks of the well-known ``chill'', and to provide a hot-air chamber and a chess-style chamber.
By installing the il in a direction that is orthogonal to the rear longitudinal direction, it is possible to reduce the wind loss as much as possible by making it possible to easily carry out one pipe of the number, and to reduce the wind loss as much as possible. Dried grains: 1
It is possible to increase the drying capacity by spraying more hot air than the 4. At the same time, by shortening the length of the hot air chamber and the exhaust chamber, even if the configuration is simple, it is possible to Is it because the durability can be maintained, or is there a lot of paddy, m, and road sand (and the grain bridging phenomenon σ that tends to occur in the past)? Prevent as much as possible and eliminate circulation unevenness due to uneven flow < 1. Not only does it help you obtain more uniformly sown and dried grains, but it also improves the drying process.
In addition to preventing dust that has entered the hot air chamber from the iJ flow path from accumulating in the hot air chamber, eliminating the possibility of fires occurring in the grain dryer, the burner device and suction/exhaust device The grain dryer is designed to be easily compatible with the factory and can be used in the workplace.σ) Depending on the installation conditions, the direction of the exhaust wind can be made to be the same as the direction of the MiJ force or the direction of backward tilt. It is intended for this purpose.

In view of the foregoing, in order to achieve the above object, the present invention has been created, in particular, by its configuration: a hot air blowing chamber of similar shape along the horizontal direction on both sides of the lower part of the dryer main body in the form of a rectangular tube long in the front and rear directions; A plurality of hot air chambers communicating with the hot air blowing chamber and a plurality of σ chambers communicating with the dust exhausting air chamber are provided symmetrically with the wind chamber, and between the hot air blowing chamber and the dust exhaust air chamber are oriented in a direction perpendicular to the horizontal direction. ) exclusion
The paddy channels are constructed alternately between the lint chambers and the groin chambers, and the lower ends of the plurality of paddy channels are connected to the feeding chamber formed by the J wall serving the lower part of the hot air chamber and the exhaust chamber. At the same time, at the bottom of the unloading chamber, there is an unloading chamber surrounded by a heat ventilation chamber, a dust exhaust air chamber, and a unloading chamber. Arranged grain drying (
A hot air blower chamber 1 and a dust exhaust air chamber of similar shapes are provided along the horizontal direction on both left and right sides of the lower part of the dryer main body, which is a horizontally long rectangular tube that is long from front to back. Between the chamber and the dust exhaust air chamber, there are a plurality of hot air chambers that communicate with the hot air blower chamber, a plurality of exhaust chambers that communicate with the dust exhaust chamber, and a paddy flow path between the two chambers, oriented in a direction perpendicular to the horizontal direction. They are constructed alternately so that
The lower ends of the plurality of hot air chambers, exhaust chambers, and paddy channels are respectively connected to a feeding chamber formed by a partition wall at the bottom of the hot air chamber and the exhaust chamber, and the lower end of the feeding chamber is provided with an ambient hot air blower. A grain dryer with a take-out chamber surrounded by a dust removal chamber, a dust exhaust air chamber, and a feeding chamber, and hot air blowing chambers of similar shape along the horizontal direction on both sides of the lower part of the dryer body, which is a rectangular tube shaped long from front to back. A burner device and a suction/exhaust device, which can be installed interchangeably, are installed on the front side of the hot air blowing chamber and the rear side of the dust exhausting room. Between the hot air blowing chamber and the dust exhausting chamber, there is provided a double fermentation hot air chamber which extends in a direction perpendicular to the horizontal direction to the hot air chamber, and a plurality of exhausting chambers which extend to the dust exhausting chamber. The plurality of hot air chambers, exhaust chambers, and paddy flow paths are constructed alternately so that a paddy flow path is formed between the compartments, and the lower ends of the plurality of hot air chambers, exhaust chambers, and paddy flow paths are connected to the lower ends of the heating chamber 1 and the υL wind chamber, which are formed by partitions. A grain dryer is provided with a take-out chamber surrounded by an ambient heat air blowing chamber, a dust exhaust air chamber, and a feed-out chamber in the lower part of the unloading chamber σ). Even if a grain dryer can accommodate the same amount of grain (σ), the number of hot air chambers, exhaust chambers, and paddy flow paths should be increased to reduce air loss in the hot air chamber as much as possible. Even if the length is the same, it is possible to achieve the same drying performance by supplying a large amount of hot air into the hot air chamber, or by shortening the length of the hot air chamber and the exhaust chamber. Also, If'a7s'r can significantly increase the total durability against material pressure and simplify the dryer itself, and increase the number of grains flowing down to reduce the occurrence of circulation unevenness due to uneven flow. The grain can be dried more evenly, and even if some of the dust mixed in the grain enters the heat chamber or ventilation chamber at the lower culm of the iVJ flow path, the dust fire will not occur. This prevents the accumulation of dirt from remaining at the bottom of the hot air chamber and ventilation chamber, and allows all of this to flow down into the feeding chamber filled with grain, thereby preventing fires in the grain dryer due to ignition and combustion of sediment dust, and reducing the risk of fires occurring during the harvesting period. Safe for all! Z', ＋It is not only possible to achieve this accurately, but also the location of the burner device i- and the suction/exhaust device depending on the installation conditions at the beam production site. In addition to being able to freely exchange dust and drying crops as the best direction for discharging dust air, if the take-out tank is formed using a grain board or the like, the hot air blowing chamber and It can be formed by using the wall plate of the dust exhaust air chamber, so it can be used for drying (),
