In-pile air circulation type drying device

Abstract

The invention discloses an in-pile air circulation type drying device. The in-pile air circulation type drying device comprises a storage area, an air inlet area is arranged on the left side of the storage area, an air outlet area is arranged on the right side of the storage area, a plurality of air inlet pipes communicating with the air inlet area extend into the left side wall of the storage area, a plurality of air outlet pipes communicating with the air outlet area extend into the right side wall of the storage area, and the air inlet pipes and the air outlet pipes are respectively provided with air holes and are arranged alternately. According to the drying device designed for meeting the in-pile circulation type drying requirement of material, reasonable structural improvements are made, the air inlet pipes and the air outlet pipes are uniformly distributed in the storage area in a penetrating mode, a plurality of short-path air circulation units uniformly distributed inside the material are formed and realize air circulation in each area inside the material, and therefore the air pressure and the air volume of fans can be reduced greatly, the energy can be saved, and all the material inside the storage area can be uniformly dried without turning the material over through power.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a high-efficiency and energy-saving drying device, which belongs to the category of energy-saving technology. Background technique [0002] For the drying of materials with small individual sizes, the prior art generally adopts a drying room or an oven to dry. In order to place more materials, the materials are generally placed in the sieve tray of the multi-layer rack in the drying room or oven. This needs to add a lot of shelves and sieve tray utensils, and it takes a lot of manpower to place and collect the materials one by one, and the drying room also needs to take up more space. The traditional technology also includes continuous drying devices with one or more layers of conveyor belts and rotary drum drying devices. In order to achieve uniform drying of all materials in the drying process, the above devices need to move the materials through power. , tumbling or s...

Problems solved by technology

[0002] For the drying of materials with small individual sizes, the prior art generally adopts a drying room or an oven to dry. In order to place more materials, the materials are generally placed in the sieve tray of the multi-layer rack in the drying room or oven. In this way, a lot of racks and sieve trays need to be added, and it takes a lot of manpower to place and collect the materials one by one, and the drying room also needs to occupy more space.

The traditional technology also includes continuous drying devices with one or more layers of conveyor belts and rotary drum drying devices. In order to achieve uniform drying of all materials in the drying process, the above devices need to move the materials through power. , tumbling or stirring, which leads to an increase in power consumption costs. The above-mentioned devices also have the problems of large equipment investment, large space occupation, and high maintenance costs. In addition, the materials will frequently collide or tumbling during the drying process, resulting in easy drying of the materials. Cause breakage, breakage or generate dust

In the prior art, materials are also placed in a drying tank with a net at the bottom, and hot air is blown from the top and bottom of the materials. If the materials are thinned, a very large space will be occupied. If the materials are stacked thickly, it will be difficult for the hot air to pass through the materials. resulting in very low drying efficiency

[0003] Drying with racks and continuous drying with conveyor belts or drum drying will cause serious waste of energy consumption. The above-mentioned technologies will use large air volumes to pass through the surface of the material, and most of the hot air does not touch the surface of the material at all. And penetrate the material, only from the space far away from the surface of the material and then discharge it, the waste of hot air is serious
