Overview of pulverized coal vibrating screen.
How it works. Pulverized coal vibrating screen is a kind of vibrating screen specially designed for blast furnace coal injection process and other pulverized coal screening processes. It uses a vibrating motor as the power source, and rotates synchronously in the opposite direction through two identical vibrating motors, so that the sieve body does periodic reciprocating motion in the direction of excitation force. This movement forces the pulverized coal to make a continuous throwing motion on the screen surface, so as to realize the screening of the pulverized coal.
After entering the screen box, the pulverized coal quickly loosens and passes through the screen. Wood chips, fibers and other debris will remain on the upper part of the screen and need to be cleaned by manual on a regular basis. In this way, the pulverized coal vibrating screen can prevent debris from entering the pulverized coal silo and ensure that the pulverized coal is transported normally in the pipeline.
The pulverized coal vibrating screen uses a high-performance vibrating motor for excitation. By adjusting the magnitude of the excitation force of the vibrating motor, the amplitude of the vibration of the sieve can be changed, so as to meet different screening requirements. In addition, the pulverized coal vibrating screen is also provided with a secondary vibration isolation system, so that the dynamic load on the foundation is small when the pulverized coal screen is running, and it can be installed on the floor slab, which improves the flexibility of use.
The screen surface is made of flat-topped stainless steel wire woven screen, and is tightened with a hook plate. This design can ensure the flatness and stability of the screen surface, thus improving the screening effect.
In short, the pulverized coal vibrating screen is driven by the vibrating motor and uses the special structure of the screen box and the screen to realize the screening of pulverized coal. Its working principle is simple but effective, and it can meet the special requirements of the blast furnace coal injection process and other pulverized coal screening processes. At the same time, the pulverized coal vibrating screen has the characteristics of good screening effect, safe and reliable work, good sealing performance, and small dynamic load on the foundation, and has been widely used in metallurgical and mineral enterprises, and has been well received.
Product Structure. Pulverized coal vibrating screen (pulverized coal screen) is a kind of vibrating screen specially designed for blast furnace coal injection process and other pulverized coal screening processes. It is composed of a screen box, a sealing cover, a vibrating motor, a secondary vibration isolation system and a chassis, etc.
The screen box is the main component of the pulverized coal vibrating screen, which relies on two identical vibration motors to rotate synchronously in the opposite direction, so that the entire participating parts vibrate in a straight line. After the pulverized coal falls into the screen box from the inlet, it quickly loosens and penetrates the screen, while sundries such as wood chips and fibers will remain on the upper part of the screen and need to be cleaned by manual cleaning on a regular basis. The screen surface is made of flat-topped stainless steel wire woven screen, and is tightened by a hook plate to ensure the screening effect.
In order to reduce the impact of vibration on the foundation, the pulverized coal screen is equipped with a secondary vibration isolation system. This system makes the pulverized coal screen have less dynamic load on the foundation during operation, so it can be installed on the floor slab, which improves the flexibility and use of the equipment.
The vibrating motor is the power source of the pulverized coal vibrating screen, which uses high-performance vibrating motor excitation. By adjusting the magnitude of the excitation force of the vibrating motor, the amplitude of the vibration of the sieve can be changed to adapt to different screening requirements.
In addition to the above main components, the pulverized coal vibrating screen also includes a sealing cover and a base frame. The function of the sealing cover is to ensure that the pulverized coal does not spill during the screening process, so as to ensure a clean and safe working environment. The base frame plays the role of supporting and stabilizing the screen to ensure its normal operation.
In general, the product structure of pulverized coal vibrating screen is simple and practical. Through reasonable design and combination, it can effectively realize the screening of pulverized coal and ensure the normal transportation of pulverized coal in the pipeline. The equipment has been widely used in metallurgy, minerals and other industries, and has won unanimous praise from users.
Installation and commissioning.
Before installing the pulverized coal vibrating screen, it is necessary to check the site foundation and the sieve installation drawing. During the installation process, the installation is carried out in the order from bottom to top, the bottom plate is installed first, and then the secondary vibration spring, the secondary vibration damping, the primary vibration damping spring and the sieve body are installed. During the installation process, it is necessary to adjust various rubber springs to ensure that they are vertical, and if there is a skew, the position of the base plate needs to be adjusted to make it vertical, and finally the bottom plate is welded together with the foundation. In addition, the steering of the two motors should be reversed.
Before using the pulverized coal vibrating screen, it is necessary to check whether the bolts of the fixed motor and the bolts of the fixed sieve plate are loose, and if they are loose, they should be tightened in time. Vibrating motors generally need to be overhauled once a year to check for bearing wear and replace with new grease. Daily maintenance work can be operated with reference to the motor instruction manual.
The installation and commissioning process of pulverized coal vibrating screen needs to be carried out in strict accordance with the operating procedures to ensure the normal operation and safety of the equipment. After the installation is completed, the commissioning of the equipment is also required to ensure that its working effect and performance meet expectations. In the process of commissioning, the excitation force of the vibrating motor can be adjusted according to the actual needs to change the amplitude of the sieve machine. In addition, the pulverized coal vibrating screen is also equipped with a secondary vibration isolation system, so that the dynamic load of the screen on the foundation is less when it is running, and it can be installed on the floor slab.
Installation and commissioning is an important part of ensuring the normal operation of pulverized coal vibrating screen, and only the correct installation and commissioning work can ensure the stability and working effect of the equipment. Therefore, in the process of installation and commissioning, it is necessary to operate in strict accordance with the operating procedures and requirements, and regularly maintain and inspect the equipment to ensure its long-term stable operation.
