Description

The utility model relates to mechanical engineering, in particular to devices for drying various materials for agricultural and industrial applications.

The well-known “Zernosushilka” (useful description was divided by patent of the Russian Federation No. 183980; IPC: F26B 17/04; publication date: 10/11/2018) containing a chamber with drying and cooling zones, a conveyor placed in it with two first and inclined downward in the direction of movement the second branches, a loader and unloader of grain, the first heat generator with hot air fans, an inclined partition between the branches of the conveyor to direct hot air from the first heat generator to the first branch of the conveyor, a transverse partition installed under the second branch of the separator and the separating space below it into the heating and cooling zones, characterized in that in the heating zone under the second branch of the conveyor a second heat generator is installed with a fan with the outlet of hot air to the heating zone, as well as a fan for supplying cold air with access to the cooling zone.

This type of grain dryer with two branches is designed primarily for drying grain material.

Also known is the “Belt dryer of pasty materials” (useful dividend to patent of the Russian Federation No. 63913; IPC: F26B 17/04; publication date: 10.06.2007), containing a belt conveyor located inside the case, heat radiators and fans for heating and air circulation inside enclosures, boot device.

The technical task of the proposed utility model is the ability to dry a wide range of different materials, such as grain, hay, straw, wood chips, sawdust, digestate, waste and others.

To solve this problem, in a belt dryer containing a conveyor belt, a first hopper, a heat generator with a hot air fan with access to the heating zone, a fan for supplying cold air with access to the cooling zone, while the heating and cooling zones are located under the conveyor and are divided by a partition, a second feed hopper with a feed rotor for laterally unloading the material onto the conveyor is additionally introduced, and the heating and cooling zones are made of sections with the possibility of rearranging towns between two adjacent sections.

The technical result of the proposed utility model is the possibility of lateral loading and unloading of loose material on the conveyor and changing the length of the heating and cooling zones depending on the type of material to be dried by moving the partition between two adjacent sections.

In FIG. 1 schematically shows a grain dryer in a side projection.

The dryer contains a conveyor belt 1, a first hopper 2, a heat generator with a hot air fan 3 with access to the heating zone 4, a fan for supplying cold air 5 with access to the cooling zone 6, while the heating zone 4 and cooling 5 are located under the conveyor 1 and separated by a partition 7. The grain dryer also contains an additionally introduced second hopper 8 with a feed rotor 9 for lateral discharge of material onto the conveyor 1, and the heating and cooling zones 4 and 5 are made of sections 10 with the possibility of rearrangement partitions 7 between two adjacent sections.

The dryer operates as follows.

The material to be dried, depending on its type, is fed into the loading area of the conveyor belt 1 from the first hopper 2 for grain material, or from the second hopper 8 for loose, bulk material using a feed rotor 9. Moving along the conveyor, the material first enters the zone heating 4, and then into the cooling zone 6, formed, respectively, by a heat generator with a hot air fan 3 and a fan for supplying cold air 5, while zones 4 and 6 are separated by a partition 7. For echeniya versatility in form of drying material by changing the length of the heating and cooling zones of the last formed of sections 10, so that between two adjacent sections 10 is mounted a partition 7 which can be adjusted depending on the desired ratio of zones 4 and 6.

Using the proposed utility model makes it possible to dry a wide range of different materials, such as grain, hay, straw, wood chips, sawdust, digestate, waste and others.

Claims (1)

A belt dryer containing a conveyor belt, a first hopper, a heat generator with a hot air fan with access to the heating zone, a fan for supplying cold air with access to the cooling zone, while the heating and cooling zones are located under the conveyor and separated by a partition, characterized in that a second feed hopper with a feed rotor for lateral unloading of material onto the conveyor is additionally introduced into it, and the heating and cooling zones are made of sections with the possibility of moving the burnout Ducks between two adjacent sections.
