Ultrasonic vibrating screening system is a simple, practical and reliable screening system. It is a new screening equipment that combines ultrasonic controller and vibrating screen. It has high screening and filtering precision and effectively solves problems due to agglomeration, static electricity and strong Screening problems such as adsorptive plugging and meshing are a major technological breakthrough in the domestic screening industry. Can be widely used in pharmaceutical, metallurgy, chemical, mineral processing, food and other industries requiring fine screening and filtration. Advantages of ultrasonic vibrating screen The screening accuracy is higher. Since the ultrasonic vibrating screen has a high frequency and low amplitude ultrasonic vibration wave, the material can be suspended in the screen surface at a low altitude, thereby increasing the screening precision of the material. According to industry insiders, the screening accuracy of ultrasonic vibrating screens is generally over 95%, while the screening accuracy of ordinary vibrating screens is generally around 60%-70%. Effectively reduce the problem of blocking the network and increase the life of the screen. It is understood that the cleaning device of the ordinary vibrating screen is a bouncing ball, which can remove the granular material, but it is not ideal for the precision powder material or some special properties. The ultrasonic vibrating screen has an ultrasonic vibration wave system, which can accurately screen the fine powder and fine powder materials that cannot be sieved by the ordinary vibrating screen. For the ordinary vibrating screen, there is agglomeration and leakage in the screening, ultrasonic vibration The sieve can also be well avoided. It converts the electric energy into wave energy through the ultrasonic transducer and transmits it to the screen surface. The agglomerated material can be broken up, the screening can be more thorough, and the multi-screen surface can be effectively cleaned. In order to achieve the purpose of not blocking the network. Today, ultrasonic vibrating screens are mainly for high-fine powder materials or materials that are easy to block. The output has been greatly improved. Due to the addition of the ultrasonic screening system, the ultrasonic vibrating screen increases the screening speed, making the ultrasonic vibrating screen produce several times the output of the powder, granules and slurry materials, which reduces the screening cost for the enterprise. Bring more benefits. Domestic screening equipment is on the rise Experts in the industry pointed out that although the advantages of ultrasonic vibrating screens are obvious, the effects of different types of screening machines are not the same. Customers should also choose the appropriate equipment according to the particularity of materials and sites when selecting. At present, China's screening technology continues to progress. Many domestic manufacturers have introduced different series of ultrasonic vibrating screen equipment. However, due to the lack of mature technology and the weak research and development strength of most manufacturers, there is still a certain gap compared with foreign screening equipment. At the same time, there are many domestic screening equipments on the market. The author was informed that Xinxiang Jinhe Machinery Co., Ltd. based on years of experience in fine grading, based on the absorption of advanced technology from peers, developed H-C series ultrasonic vibrating screen (fine sieving machine). This ultrasonic vibrating screen converts 220v, 50hz or 110v, 60hz electric energy into 18khz high-frequency electric energy, and inputs it into an ultrasonic transducer to turn it into 18khz mechanical vibration, thereby achieving the purpose of efficient screening and clearing. Fine powder screening is easy. The system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen based on the traditional vibrating screen to improve the screening performance of the ultrafine powder. It is especially suitable for users of high value-added fine powders. Compared with the screening equipment on the market, the H-C series ultrasonic vibrating screen has several characteristics. "Improve the flat drop of the low-density powder in the gravity settlement (light contact between the powder and the mesh port), the slip effect, improve the retention or wedging of the high-density metal at the mesh opening, improve the adhesion effect of the electrostatic powder, thereby improving Screening efficiency and screening quality. The screening pass rate indicates that the pass rate is generally 50%-400% higher than without the ultrasonic vibrating screen.†The company's technicians said that the equipment can also reduce or eliminate the net. Time, eliminate cross-contamination, stabilize screening accuracy, and reduce the number of screenings. At present, this equipment has been used by many domestic pharmaceutical, mineral processing and other enterprises. Future screening machine development direction With the rapid development of China's pharmaceutical, food and other industries, the market's requirements for the variety and quality of vibrating screens have also been continuously improved, thus improving the development of vibrating screens to a new stage. In view of the situation of domestic and foreign screening machines, the industry believes that the future screening machine will develop in the following directions: High efficiency and high yield. The industrial modernization process has led to an increase in the scale of enterprises, and the production capacity of enterprises has been greatly improved. More efficient high-capacity screening machines are needed. Standardization, serialization, and generalization development. The standardization of screening equipment is conducive to the design, organization of specialized production, quality assurance, and the cost reduction. The vibration intensity increases. The vibration process of the sieve machine is gradually strengthened, that is, the vibration parameters of the sieve machine are increased, so that a large speed and acceleration are obtained, and the production capacity and the screening efficiency are improved. Environmental protection and simplified structure. At present, it is an era of promoting energy conservation and environmental protection. Regardless of the pharmaceutical, food and other industries, the requirements for equipment are all environmental protection, situation, and simplicity. With the development of society, the future trend will become more obvious.
