Scraper Arch Breaker
- High-Quality Material Guarantee: The main body is made of SUS304 stainless steel, which has stable physical properties. It is not only corrosion-resistant and wear-resistant but also meets the hygiene level requirements of the food and pharmaceutical industries, avoiding contamination when materials come into contact with the equipment. SUS304 stainless steel scraper arch breakers are safe for food-grade applications.
- Simple Structural Design: The overall structure has no complex redundant parts and adopts a "bolt-free" assembly process, reducing gaps for material accumulation and cleaning blind spots. During daily maintenance, there is no need to disassemble complex components; only the scraper wear condition and gear lubrication status need to be checked, which greatly reduces maintenance costs and downtime. Low-maintenance scraper arch breakers save production costs for factories.
- Long Service Life: The core transmission components (gears) adopt precision machining technology, and combined with the wear-resistant treatment of the scraper, mechanical loss during operation is reduced. At the same time, compared with chain transmission, the gear transmission method avoids the risk of chain loosening and breaking, and the average service life of the equipment is more than 30% longer than that of traditional discharging equipment. Long-life scraper arch breakers reduce equipment replacement frequency for manufacturers.
- Significant Arch-Breaking and Wall-Cleaning Effect: The design of the scraper making circular motion along the silo wall can directly act on the retained materials on the side walls and bottom of the silo. It not only solves the "bridging" and "hollowing" problems but also cleans the materials attached to the silo wall, avoiding caking and deterioration caused by long-term material retention and improving material utilization rate. Scraper arch breakers with excellent wall-cleaning function enhance production efficiency.
- Alleviating Material Segregation: For mixed materials with uneven particle sizes, traditional discharging methods are prone to "segregation" (large particles concentrate at the bottom and small particles concentrate at the top) due to different particle settlement speeds, which affects subsequent production quality. The scraper arch breaker keeps the materials in a mixed state during the falling process through the uniform stirring and pushing of the scraper, effectively alleviating the segregation problem. Scraper arch breakers prevent material segregation for consistent product quality.
- Quiet Operation Experience: The gear transmission link adopts a high-precision meshing design, and combined with the lubrication treatment of bearings, the noise during operation is controlled below 60 decibels (equivalent to the volume of daily conversation), avoiding the harsh noise of traditional discharging equipment during operation and improving the workshop working environment. Quiet scraper arch breakers create a comfortable working environment for production line engineers.
- Wide Hopper Angle Adaptability: It can adapt to hopper angles within 45°. Whether it is a vertical silo or an inclined silo, accurate connection can be achieved by adjusting the installation angle, without the need for large-scale modification of the existing silo structure. Scraper arch breakers with flexible hopper angle adaptation fit various silo types.
- Rich Specifications and Customization Options: Standard caliber specifications from φ40 to φ500 are provided, covering different needs from small laboratory equipment to large-scale industrial production lines. For large-caliber needs beyond the standard caliber (such as above φ500), exclusive equipment can be customized through technical consultation according to the customer's silo size and material characteristics, ensuring seamless connection with the existing production system. Customizable scraper arch breakers meet diverse industrial needs for purchasers.
- Expandable Blade Design: It supports the installation of multiple scraper blades (the specific number is determined according to material fluidity and discharging volume). The more blades there are, the higher the discharging efficiency and the more uniform the material stirring, which can be flexibly adjusted according to the actual production rhythm. Expandable blade scraper arch breakers optimize discharging efficiency for different production beats.
Overview
In the industrial production field, the storage and discharging processes of powder and granular materials often face problems such as bridging, hollowing, and segregation, which seriously affect production continuity and material utilization rate. Scraper arch breakers, as key discharging equipment, are widely used to solve these issues in various industries.As the core auxiliary discharging equipment at the bottom of silos, scraper arch breakers effectively address the above pain points with their scientific structural design and excellent performance, and are widely applied in industries such as chemical engineering, food processing, pharmaceutical manufacturing, and building materials.
Core Components of Scraper Arch Breaker:
The stable operation of a scraper arch breaker relies on well-coordinated core components, each performing its respective function to jointly ensure the efficient and smooth discharging process. High-quality scraper arch breaker components are essential for long-term equipment reliability.
Drive System: With a motor as the power source, it provides continuous and stable driving force for the equipment to ensure no jamming in the transmission link. Equipped with high-precision gear components made of high-quality alloy materials, it features high transmission efficiency and low wear rate, which is crucial for the long-term operation of the scraper arch breaker.
Bearing and Conveying Structure: It consists of two core parts: the shell and the scraper. The shell is made of SUS304 stainless steel, which has high material density and strong corrosion resistance, and can meet the contact requirements of materials with different properties such as chemical raw materials and food powders, avoiding material contamination and equipment rust. The scraper is customized according to material hardness and fluidity, and its surface is subjected to wear-resistant treatment, which ensures the arch-breaking effect while extending its own service life. SUS304 stainless steel scraper arch breakers are ideal for food and pharmaceutical industries.
Auxiliary Structure: The equipment adopts an overall design without redundant bolts, which not only simplifies the assembly process but also reduces the "dead corners" of material accumulation, lowering the difficulty of cleaning and maintenance. Some models can be equipped with sealing components as required, making them suitable for material scenarios with easy dust generation and volatility. Sealed scraper arch breakers are perfect for handling volatile materials.
Working Process of Scraper Arch Breaker:
Scraper arch breakers are usually installed at the bottom of silos and accurately connected to silo outlets. The specific working steps are as follows. Proper installation of scraper arch breakers ensures optimal discharging performance.
Material Inlet: The powder and granular materials stored in the silo naturally fall into the feeding area of the scraper arch breaker under the action of gravity, forming a stable material supply. Scraper arch breakers ensure consistent material flow for continuous production.
Power Transmission: After starting the motor, the motor drives the gear components to operate, and transmits power to the scraper structure through gear meshing transmission. The high-precision gear transmission of scraper arch breakers ensures smooth power delivery.
Arch Breaking and Discharging: Driven by gears, the scraper makes uniform circular motion along the inner wall of the silo. During the movement, the scraper directly acts on the materials at the bottom and side walls of the silo, breaking the "bridging" (materials form an arch structure in the hopper, hindering falling) and "hollowing" (materials in the center of the silo fall while materials around remain) phenomena caused by adsorption force and electrostatic force between particles, forcing materials to fall evenly into the discharging channel and completing stable conveying. Efficient arch-breaking of scraper arch breakers improves material utilization rate.
