The industrial dryer is mainly through the heat source of the dryer comes from the combustion device. This dryer uses a smooth flow heating method.The leaf is dried in thermal source, and then the outlet is out of the mouth, and the exhaust of the material.Next, lets learn about the industrial dryer with the editor below!
The principle of the dryer
The heat source of the industrial dryer comes from the combustion device, and the dryer uses a smooth flow heating method.Therefore, the material that needs to be dried must be pushed back from the feed box and the feed, that is, it is pushed back by the spiral copy plate.Because the dryer is placed, the materials are flowing to the back end under the action of gravity and turning, and on the other hand, the materials are repeatedly copied by the copied board, and the upper end is continuously sprinkled.The curtain is fully exchanged with the thermal airflow in the cylinder. Due to the recovery of the material, the water contained in is gradually dried, thereby achieving the purpose of drying.
Dryer classification
There are many types of industrial dryers and can be divided into three categories:
1. Root dryer: Rattler-Drying Machinery is one of the traditional drying equipment. The equipment is reliable, large operation, strong adaptability, and large processing ability.Coal washing, fertilizer, ore, sand, clay, kaolin, sugar and other fields, diameter: φ1000-φ4000, the length of length depends on dryness requirements.
The drum -type dryer mainly includes three forms: a single back -back dryer, a dual -back dryer and a three -back dryer.Among them, the three -back dryer occupies a small ground, and the low energy consumption is the most advantageous.
2. Tunnel -type dryer: The tunnel -type dryer is absorbing the drying machine developed by advanced drying technology abroad. It loaded the material through a car, which makes full use of effective drying and empty air, suitable for a variety of shape materials drying drying.EssenceThe whole machine is divided into several warm and humid bottom sections. The material is transformed in the dry medium of drying medium through the entire drying range.
3. Box dryer: The box dryer uses a double -layer tracking to remove the damage to the surface of the material. It adopts measures such as a two -way cross flowing method, adjustable stalls, and increased the average materials to ensure product moisture.Uniform and consistent. Drying temperature, the stay time of the material in the machine, and the thickness of the material can be intelligently controlled by the computer. Because 50%-95%of the heat wind can be used and using the insulation box, it greatly reduces energy consumption and production costs.There is an automatic cleaning mechanism at the bottom, automatic cleaning, and all the plates are cut with laser cutting to prevent the body from deformation due to artificial cutting. It is suitable for the drying treatment of high -end puffed particles, pet feed, and can also be used for food, food, and food, and food, food, and food, and food, food, and food, and food, food, and food, and food, food, and food, and food, food, and food.Dry treatment of granular and sheet materials in chemical industry and other industries.
The above three types of industrial dryers can be divided into three different heating methods according to their energy supply: A electric heating type.B steam heating type.C gas (oil) heating type.
Dryer installation technology
1. Basic acceptance:
Mainly check the basic concrete pouring quality and size position deviation: the appearance requires the basic surface of the basic surface, no oil pollution, dust, debris, no steel bar, no cracking angle, no residual shell board in the holes, and other pouring defects.For basic dimensions and position deviations, the following requirements should be met: the shape size and the basic coordinate position, the vertical axis error is less than 20mm.Different plane elevation errors are less than 20mm.Just promise not to promise the positive; the slope error is less than 20mm, and the discharge side promises not to promise positive;
2. Equipment acceptance:
Contrast the equipment packing form provided by the dryer manufacturer, and take stock of parts, components, scale parts, random files, etc., check whether there are errors and missing parts, deformation damage, etc.Procurement or preparation.Clear the protective coating of the painting and dust, oil, and rust of the decoration during packaging, and check the damage deformation caused by the trimming during transportation and loading.Pre -testing and pre -installation of parts and hubs to avoid rework during installation and ensure the progress of installation and installation.
3. Preparation and installation process:
Basic installation program.Formulate various working order and content of components cleaning, detection, transportation, assembly testing, and adjusting trial operation.Installation process method.For important parts or hubs, write detailed detection and installation methods, quality requirements, technical scale, deviation range, and tools required.Safety technical requirements.In the formulation of assembly homework, in order to avoid possible accidents, safety measures must be taken, the command in the homework, the manipulation regulations for installation of the hub, and special attention to matters.Possible hidden dangers and preventive measures for accidents, electrical lines, and pipelines, etc.
