Flip Flow Screen Specializes In Solving Sticky And Wet Material Clogging Problems
In the huge system of industrial production, the screening link is like the key components in the precision gear group, although it seems insignificant, it plays a decisive role in the smooth operation of the entire production process and product quality. From the classification and screening of ore in mining, to the fine classification of sand and cement raw materials in the production of building materials, to the strict screening control of raw materials and finished products in chemical, food, medicine and other industries, screening technology is everywhere, it is the core link to ensure that products meet quality standards, improve production efficiency and reduce costs.
However, the traditional screening equipment in the face of complex and diverse materials and increasingly stringent production requirements, gradually revealed many limitations. For example, when dealing with wet, viscous or fine-grained materials, the ordinary vibrating screen often encounters the problem of screen blockage, resulting in a sharp decline in screening efficiency, production is forced to interrupt, frequent cleaning and maintenance work not only consumes a lot of manpower and material resources, but also seriously affects the production schedule and the economic benefits of the enterprise. It is against this background that the flip flow screen came into being, bringing a profound change to the field of screening with its innovative design and excellent performance.
How it works is revealed
One of the core technologies of flip flow screen is the bi-plastid subresonance principle, which gives it excellent screening performance. It consists of a fixed screen frame with linear vibration and a floating screen frame with excitation to form an exquisite resonance system. When the device is started, the motor drives the shaker to work, and the two shafts of the shaker equipped with a fan pendulum block are closely connected through the gear, rotating in reverse at the same speed, producing a shock force along a constant straight line, which is the amplitude line of the tension screen. In this process, the fixed screen frame produces basic vibration, while the floating screen frame produces additional vibration under the action of resonance, and a clever relative motion is generated between the two. This unique movement mode lays a solid foundation for the efficient work of the subsequent elastic polyurethane screen surface, just like a well-choreographed dance, the coordinated movement of the two screen frames is the opening prelude to the entire screening process.
Elastic polyurethane sieve surface mystery
Another key element of the flip flow screen is the elastic polyurethane screen surface, which plays a central role in the entire screening process. Due to the relative motion of the fixed screen frame and the floating screen frame, the two ends of the polyurethane screen surface are respectively installed on the fixed beam and the floating beam on the floating screen frame. During the screening process, the polyurethane screen surface is continuously expanded and contracted at an astonishing frequency of 800 times per minute. This high frequency relaxation motion makes the screen surface obtain an acceleration of up to 50g. Such a high acceleration is like a powerful “clean guard”, which can produce a strong force and effectively prevent the screen from being blocked by the material. When the material comes into contact with the rapidly relaxed screen surface, those particles that may cause the screen to clog will not be attached to the screen under the rapid change of the screen surface and high acceleration, but will be quickly bounced off or under the screen, thus ensuring that the screen surface is always unimpeded and the screening work can be carried out efficiently and continuously.
In the field of screening, materials with large viscosity and high moisture have always been insurmountable obstacles for traditional screening equipment. However, the flip flow screen easily breaks this deadlock with its unique design. 50G acceleration is the flip flow screen’s key weapon to overcome difficult to screen materials. When the material falls on the rapidly relaxing screen surface, the high acceleration causes a strong force between the material and the screen surface. For viscous materials, this force can overcome the viscous force between materials, so that they can not adhere to each other and block the screen; For materials with high moisture content, high acceleration can quickly separate water from the material, avoiding the accumulation of water on the screen surface leading to screen blockage. Just like in the coal washing industry, in the face of wet and sticky raw coal, the traditional screen is often inefficient due to screen blockage, but the flip flow screen can efficiently grade the raw coal according to the size of the production to ensure the smooth progress, greatly improving the efficiency and quality of coal washing.
In industrial production, the reliability and maintenance cost of equipment are the focus of attention of enterprises. flip flow screen performs well in this regard, providing enterprises with reliable operation assurance and low-cost maintenance solutions. Its linear motion box exciter is an important guarantee of reliability. The structure design of the exciter is reasonable, the operation is stable, and it can work continuously for a long time, reducing the downtime caused by the failure of the exciter. The specially designed polyurethane screen plate can withstand 50g vibration strength and 800 curvature per minute, with excellent wear resistance and fatigue resistance, greatly extending the service life of the screen plate. The screen machine is supported by hollow rubber spring, which can not only effectively absorb shock, reduce noise, but also has a long service life, reducing the frequency and cost of replacing the spring. In addition, the “U” shape design of the side part of the screening machine forms a good seal, preventing the screen from entering the screen under the screen, while avoiding the wear of the side plate; The screen plate is fixed with wedge-shaped rubber strip without bolts, which is convenient and quick to disassemble and reduce the maintenance time and workload. The combined effect of these designs makes the flip flow screen operate with high reliability, less daily maintenance workload and greatly improved equipment utilization.
