Inert gas protection airflow explosion explosion. The whole system has explosion-proof holes in different positions in the whole line, which minimizes the loss during the bursting and explosion caused by the internal pressure and concentration of the system. The motor and other devices used in the whole system are explosion-proof motors, and the sealing performance is better, which effectively reduces the accumulation of dust.
Airflow classifier can achieve efficient screening and precise grading of titanium alloy powder, is essential for the process of distinguishing titanium alloy powder particle size, then which airflow classifier is more suitable for titanium alloy powder What is the grading screening? This has to mention the inert gas protection airflow classifier produced by Shandong Erfa. The device can accurately grade the titanium alloy powder, while dispersion, preventing the raw material from exploding due to contact oxygen, Safety performance can be said to be one of ZUI in the airflow classifier.
The inert gas protection airflow classifier is based on the airflow classifier, with nitrogen or carbon dioxide as a pulverized working medium, a nitrogen compression system, a nitrogen filter system, a crushing system, a grading System, collection system, plus, unloading system, nitrogen purity test supplementary system, nitrogen system, and electrical control system composition. The production and manufacturing process of complete equipment is a mature technology, reliable quality, and stable performance. Wide application has been widely used in metal powder, volatilized raw materials and flammable and explosive materials.
Gas protection airflow classifier The entire production line is operated with full enclosed negative pressure cycles, most of which use PLC programming control, minimizing human operation and control factors, control cabinets can be placed In a separate control room in the distance, the packaging discharge is automatically packaged, and the on-site observation uses the monitoring probe, which can be completely unattended.
Safety, the FW inert gas protection airflow classifier mainly has the following features:
1, isolated oxygen. Before the equipment is started, the air in the closed circulation system is started, and the air is closed, and the discharge system can be replaced with a small amount of air brought by the addition and discharge process, and maintains the content of the system in the system.
The oxygen content tester is continuously monitored in the gas stream, and nitrogen is added immediately when it exceeds a certain degree, so that the oxygen content is maintained within the safety production standard.
2, control the gas powder concentration. Equipment supporting feeding systemIn order to completely enclosed, a uniform device, controlled by the control cabinet. Fully enclose the effect of isolating oxygen, uniform speed, controls the material concentration inside the added device, and can be arranged any.
The material that is uniformly added to the device is accumulated in the device, and the security is not guaranteed. Therefore, the device profile, such as the bending angle of the pipe; the shape of each component is scientifically calculated, and the dead angle inside is eliminated, and the powder is not accumulated in the pipe through the high-speed airflow through the equipment.
3. Release static electricity and eliminate the source of the source. The pulsed anti-blow collector can eliminate static electricity in time, while ensuring the pulse clear ash clean thoroughness. The equipment is all metal components, all grounded to try to release powder static electricity.
4, circulating air cooling. Because the system is a closed circuit loop system, there are multiple moving parts inside the device, and a certain temperature is generated in the high speed movement, while the temperature is critical to safety in the machining. Therefore, a heat sink cooler is installed on the pipe, which can effectively reduce the safety hazard caused by the equipment for a long time or in high temperature environment.
5, explosion-proof. The whole system has explosion-proof holes in different positions in the whole line, which minimizes the loss during the bursting and explosion caused by the internal pressure and concentration of the system.
The motor and other devices used in the whole system are explosion-proof motors, and the sealing performance is better and effectively reduces the accumulation of dust.
6, emergency stop. The equipment emergency shutdown trigger switch is connected to the oxygen content tester, and the oxygen content concentration monitors by the oxygen content tester has not reached the preset value in a predetermined time, triggered emergency shutdown, the equipment stopped, the introduction of the wind, the grading machine Delayed, the nitrogen supplement system continues to work until the manual shutdown.
The gas protection airflow classifier adds a major role in the screening grade of titanium alloy powder, and has been widely used in numerous domestic processing enterprises.
In the ultrafine pulverized laboratory of ALPA, there is a small test, a mound, small production ultrafine powder gas flow pulverizer, particle size detection, powder characteristic detection related instruments, The nature of different raw materials can be accurately analyzed, providing 5G-50KG batch raw material processing, rich micropowder experience and professional crushing equipment can greatly reduce the retrieval research and development cycle, andSolve the various problems encountered during the micronization process, welcome friends in need to call us!
