Introduction to reciprocating precision swing screen

　　Henan Xinxiang Square Swing Screen ManufacturerThe square swing screen produced is a screening equipment with high precision and large output. It has excellent self-cleaning effect, high screen utilization rate, long service life, and good sealing effect. It is widely used in industries such as chemical and new materials, metallurgy, metal powder, mineral powder, food, salt, sugar, abrasive, and feed. In the past, pursuing screening accuracy alone would sacrifice output, while pursuing high output would lead to a decrease in accuracy. The square swing screen was born to solve this dilemma as a screening equipment with both high accuracy and high output. It is a new type of screening equipment developed and designed by Jinhe vibrating screen based on the introduction of excellent foreign technology.

Due to the use of the principle of planar rotation in the equipment, compared to traditional linear screens with the same screening efficiency, the square precision swing screen significantly reduces the dynamic to static ratio and basic dynamic load of the equipment during operation. Coupled with the cleaning device below the screen, it achieves a significant reduction in working noise and greatly increases the effective screening area of the screen, increasing the screening efficiency from 85% to 95% to 98.5%, while also improving the service life of the screen. In short, the reciprocating precision swing screen is a new equipment developed for customers to meet the needs of high precision and large output. It imitates the slight elliptical swing and upward arc motion of human manual screening, and is particularly suitable for irregular materials such as cylindrical and sheet-like shapes. It has the advantages of high screening efficiency, large output, and long service life. The reciprocating precision swing screen has high screening efficiency, high screen utilization rate, stable and reliable operation, does not damage the particle shape and surface structure, and is designed to accommodate 9 layers of screens or 2 sets of four layers of screens at once according to the mesh size of fracturing sand screening. Its production capacity is much higher than that of ordinary linear screens.

▌Henan Xinxiang Square Swing Screen ManufacturerCharacteristics of Swing Screen in Production

1) The self-cleaning effect is good, and it is equipped with a specialized cleaning device - bouncing ball. During the movement of the screen body, it can bounce on the punching plate under the screen, continuously hitting the metal mesh to achieve dust removal under closed conditions. It can efficiently clean the mesh, reduce mesh blockage, reduce screen maintenance time, and extend the use time of the screen.

2) This device has a tight sealing design, with better sealing effect, no dust flying, and no dust leakage phenomenon. The screening machine has low vibration and noise, meeting environmental protection requirements.

3) The reciprocating precision swing screen adopts the principle of plane rotation, works with inertia force, and is flexible in screening. The acceleration is 4-5 times lower than that of ordinary vibrating screens, which improves the distribution of materials on the screen and effectively increases the utilization rate of the screen mesh. And the noise is relatively low, as low as 75 decibels;

4. The reciprocating precision swing screen is particularly suitable for irregular materials such as cylindrical and sheet-like shapes. The screening accuracy is improved by 90% -95%, which is several times or higher than that of ordinary vibrating screens, and the service life is 3-5 times that of ordinary equipment

5. The replacement method of the reciprocating precision swing screen adopts a front or rear end design that can open the structure. When the screen needs to be replaced or inspected, it can be easily pulled out, saving time.

Working principle of reciprocating precision swing screen

The vibration force generated by the motor drive device of the reciprocating precision swing screen is an inertial force that changes in a certain pattern around a fixed axis and direction. Essentially, it is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the square swing screen, its screen surface is generally arranged horizontally or slightly inclined (with an inclination angle of 0 °~5 °). The working principle of the square swing screen is that after the swing screen is started, the shaking body of the equipment, that is, the screen box, moves back and forth under the action of inertia force. The screen box and the screen surface are connected for periodic shaking, so that the material on the screen surface moves in a planar rotary motion together with the screen box. During this period, materials smaller than the sieve aperture fall to the lower layer through the sieve aperture, becoming undersized materials. Materials larger than the sieve aperture are discharged from the discharge port after continuous rolling and jumping movements, ultimately completing the screening process. From the working principle of the square swing screen, it can be seen that the eccentric track of the transmission mechanism has a crucial impact on the material movement trajectory and the retention time of the material on the screen surface, which has the opposite effect on the processing capacity and screening efficiency of the screen machine. In actual screening operations, we can make trade-offs between production capacity and screening efficiency based on specific circumstances.

In this process, the reciprocating screen uses an eccentric structure to make the screen surface perform uniform reciprocating and rotary motion. The slightly inclined screen surface allows the material to quickly pass through the sieve, achieving high efficiency and high output in screening. The contact time between the material and the mesh is not long, so the probability of sieving is high, the screening powder output is large, the screening accuracy is high, and the screening machine has little damage to the structure of the material itself. It has more advantages in screening materials of different specifications, and in terms of noise and maintenance, it is lower than the industry level.

▌ Maintenance Guide for Reciprocating Precision Swing Screen Products

When conducting a weekly inspection of the square swing screen, all loose bolts of the equipment should be tightened, especially the bolts of the exciter, screen surface, and support device. Rough operation is strictly prohibited to prevent damage to the equipment.

2. Carefully check the tension of the triangular belt of the equipment in daily life, and tighten it appropriately if necessary.

3. The screening frame is an important component of the equipment, and it is necessary to pay more attention to the welding seams of the main beam and all crossbeams in daily life to ensure that the welding seams are tight and there will be no cracks.

When maintaining the screen mesh, it is necessary to replace the severely worn screen mesh. Even if it is a new screen mesh, it should be re tensioned every 4-8 hours until it is fully tensioned.
