1. Core role: ensure the smooth and efficient operation of the conveyor system
As a key load-bearing component of the belt conveyor, the core role of the DTII. parallel lower idler group is concentrated in three dimensions: first, it is uniformly load-bearing, through the full fit with the lower surface of the conveyor belt, the weight of the material and the weight of the conveyor belt itself are evenly transmitted to the frame, so as to avoid the deformation or damage of the conveyor belt caused by excessive local force; The second is to reduce the running resistance, the idler replaces the sliding friction through rolling friction, greatly reduces the friction loss during the operation of the conveyor belt, improves the conveying efficiency and saves energy consumption; Finally, maintain the posture of the conveyor belt, through accurate spacing arrangement and horizontal positioning, ensure that the conveyor belt maintains smooth operation during long-distance and high-load conveying, effectively prevent deviation, snaking and other faults, and ensure the continuity and safety of the conveyor system.
2. Structural composition: modular design, taking into account strength and adaptability
DTII. parallel lower idler group adopts a standardized modular structure, the core components include idler body, bearing housing, shaft and connectors, and each part works together to ensure the overall performance:
Idler body: as a direct bearing component, the material is mostly seamless steel pipe, the surface is anti-corrosion treatment (such as galvanizing, spraying), according to the bandwidth requirements are divided into 89mm, 108mm, 133mm, 159mm and other diameter specifications, the length is adapted to 500mm-1400mm different bandwidths to ensure full contact with the conveyor belt;
Bearing system: equipped with 4G204, 4G205, 4G305, 4G306 and other series of deep groove ball bearings, with good rotation accuracy and load-bearing capacity, with the sealing structure to effectively prevent dust and water vapor intrusion, extend the service life;
Support structure: including shaft, bearing housing and connecting bolts (using M12, M16 and other specifications), the bearing housing and the frame are accurately positioned and installed to ensure the horizontality and parallelism of the idlers, and the modular design is convenient for disassembly and maintenance;
Auxiliary parameters: Through the standardization of key dimensions such as E (total length), A (working length), H (installation height), P/Q (positioning size), etc., the perfect adaptation with DTII. belt conveyor is realized to meet the installation needs under different working conditions.
3. Application scenarios: Adapt to multiple industries and cover complex working conditions
As the core supporting components of DTII. series belt conveyors, DTII. parallel lower idler sets have been used on a large scale in many industries with their stable performance and wide adaptability:
Bulk material transportation field: suitable for coal, ore, sand and gravel bulk material transportation in coal mines, metallurgy, electric power, ports and other industries, which can match the working conditions of long distances, high belt speed, and large conveying volume, and ensure the continuous and efficient transfer of materials;
Industrial production line: In the production process of building materials, chemical, grain processing and other industries, it is used for the horizontal conveying of semi-finished products or finished products, and cooperates with the conveyor belt to achieve seamless connection between processes.
Adaptation to special working conditions: By selecting different bearing models and anti-corrosion treatment processes, it can adapt to a variety of working conditions such as room temperature, dust, and light humidity, and its standardized drawing system (such as DTII.01C2111, DTII.03C2133, etc.) is convenient for quick selection according to the conveying volume, bandwidth, and material characteristics, reducing the cost of system configuration.
4. Technical advantages: the dual guarantee of standardization and reliability
The core advantages of DTII. parallel lower idler groups stem from their rigorous standardized design and engineering validation:
Adopting DTII. series standards, all parameters (size, material, bearing capacity) have been verified by engineering practice to ensure compatibility and interchangeability with belt conveyors, and reduce spare parts procurement and maintenance costs;
With low rotational resistance and low operating noise, with high-precision bearings and optimized structural design, the service life can reach more than 20,000 hours, reducing the frequency of downtime and maintenance;
For different bandwidths (500mm-1400mm) and load-bearing needs, multi-specification combination options are provided, and the bearing capacity can be flexibly matched by adjusting the idler diameter and bearing model to meet the differentiated needs of conveyor systems from light to medium and heavy-duty.
