1. Â Application
The belt dryer is mainly for mass production of continuous drying good permeability sheet, strips, granules and grainy materials. This series dryer has the advantages of high drying speed, high evaporation intensity and good quality final product.
2. Â Technical Parameters
1)Â Equipment name: continuous mesh belt type drying machine.
2)Â Mesh belt width: 0.5-1.5 mm
3)Â Mesh belt layers: can be 3, 5, 7 layer (different capacity and grain moisture requires different layers and drying case length)
4)Â Drying temperature: 80-150 degree
5)Â Water evaporation capacity: 20-120 kg/h
6)Â Mesh belt feeding speed: 2-9 m/h (frequency speed regulation)
7)Â Heating method: Optional with electric heating, steam heating (steam press is 0.3-0.6Mpa), oil heating etc to be heat source. Most commonly used electric heating and steam heating.
3. Â Working Principle
The material is evenly spread on the mesh belt; the material gets moved from the forward to discharging side by motor drive, complete the drying process.
Under the action of the circulating fan, the air inside drying case goes through mesh belt turn to material. Air first goes through steam exchanger or heat pipe reach to required drying temperature. Then touches mesh belt layers, complete the heat transfer process.
At that moment, the air temperature goes down, water content increased, part of the wet air discharged by fan, the other part mixes with normal temperature air cycle for second drying; in order to achieve the full utilization of energy.
Temperature and moisture inside the case can be controlled by combined device of eliminate moisture and steam supply electric heating temperature control device.
At the end of drying period, if need to cool down the product, just turn off steam valve or electric heating device to stop the heating, through the suction of normal temperature air to cool the products.
4. Â Main Structure
1) Â Transmission system
Adopts mesh belt motor (frequency speed control) + reducer + chain transmission combination structure. Mesh belt running speed can be completed by adjusting motor running frequency.
2) Â Conveying system
Conveyor system consists of driving wheel, conveyor chain, tensioning device, supporting rod and mesh belt. Both sides of chain are connected through a supporting rod, a chain wheel and steel rail positioning. Mesh belt is fixed on the supporting rod, run along with chain and rod. Driving wheel is installed at the discharging side.
3) Â Drying room
The drying room is divided into main room and air ducting two parts. It has the observation door at the main drying room; the pendent design of bottom is convenient for cleaning the accumulated material.
4) Â Temperature control
Steam Auto control electromagnetic valve, controls drying temperature of every parts, manual valve unit is mainly set according to the metal thermometer; there's a temperature controller at the electric cabinet for electric heating.
5) Â Electric control system
See the principle diagram of electric control
The Star Type Unloader is used to install the discharge port of the discharging device under the negative pressure, the upper part accepts the material discharged from the discharging device, and the rotating impeller plays the role of conveying the material, and also acts as a seal to prevent the air from the discharge port during the pneumatic conveying process, ensuring the normal discharging of the discharger as a special kind of material. The unloading equipment plays a very important role in cleaning and cleaning. Therefore, it is necessary for us to summarize some of its characteristics so that we can better understand and maintain the star type unloader in an all-round way and give full play to its maximum ability.
The star type unloader can be used in the collection material system, as the discharging device of the silo, and the most advanced discharging device in the Star Type Discharger at present. It is often used as one of the important equipment of dust removal system in the dust removal system. It is especially suitable for dust. Small particle material is deeply affected by environmental protection, metallurgy, chemical industry, grain, cement, road building, drying equipment and so on. The engineering projects of the industry are preferred.
The characteristics of Star type discharger: 1, compact structure, beautiful appearance, easy to use. 2, the operation is smooth and the noise is low. 3, because of the distance between the bearing and the gear box leaving the shell, the lubrication has been greatly improved for high temperature. 4, it can be designed and manufactured according to the requirements of the user. 5, products should be lubricated with special grease for pin wheel cycloid reducer before they leave the factory. Please check the fuel regularly.
