The use of airflow crusher in the ultra -micro -laboratory has been widely used, such as Chinese medicine, western medicine, pesticide, biology, cosmetics, food, feed, chemical and other industry -wide dried materials. Especially for the shattering effect of fibrous, high toughness, high hardness and other materials, it is more perfect.
Laboratory air flow crushing machine
In daily production, on the one hand, the product output is increased, and on the other hand Equipment also often occurs in some failures. So what should we pay attention to in the usual process? I. Preparation of the laboratory air flow crusher 1. Check the host, connecting machine, pipeline, valve, etc. Must be in a good state. 2. Set the frequency and bandwidth of the pulse controller to ensure the smooth flow of the filter bag. Second, turn on 1. Before turning on the air compressor and freezer, turn on and export the cooling valve to ensure the normal flow of cooling water. 2. The starting operation of the compressor shall be performed in accordance with the instructions of the compressor. 3. The pressure regulator of the compressor can adjust the pressure of the storage tank to make it greater than the pressure of 0.1 MPA. 4. Open the frozen dryer to confirm whether the pressure meets the requirements. 5. Open the shaft cleaning valve and the air sealing valve, adjust the pressure to 0.1 0.3 mPa, and then start the hierarchical wheel, and gradually adjust the speed required by the inverter from scratch. 6. Turn off the fan adjustment valve, open the fan, and then gradually open the fan import valve to adjust the required air volume. 7. When the crushing pressure reaches 0.8 MPa, open the main air valve; turn on the anti-blowing valve, the pressure of the anti-blow valve reaches 0-4-0.6 MPa; then open the whirlwind separator and the catcher valve. 8. Pay attention to the control position when loading, and check whether the limit of the hierarchical impeller current meets the requirements. If not, it should be reset.
3. The operation stipulates that the system adopts advanced PLC+touch screen control method. The terminal touch screen is the operation of the system. It is important. Fourth, stop 1. Stop the spiral feeder feeding. 2. Turn off the main air valve and stop compressor. 3. Turn off the winding valve and stop the fan. 4. Stop the division impeller motor and turn off the cleaning valve and sealing valve. 5. The whirlwind separator and the capture device unloading valve. 6. After the shutdown is over, turn off the control box power supply. 5. Precautions 1. When running the discharge device, it is strictly forbidden to reach into the exit of the unloader to prevent the hand from hurting the hand. 2. Rapid impeller speed cannot exceed the specified value, otherwise the graded wheels and motors will be destroyed. 3. The safety valve must be checked regularly. 6. Maintenance and maintenance of the laboratory air flow crusher 1. The operation and maintenance of the fans. Remove the dust inside the fan every week, especially the ash dirt at the leaves. Add lubricating oil to the bearing box every month (2#calcium sodium base lubrication). In the process of turning on and running the fan, if there is abnormal noise inside the fan, or the fuselage vibration should be stopped immediately. 2. Each host is twelveCheck the wear of the hierarchical impeller, spiral feeder, and crushing nozzle. After 200 to 300 hours of crushing materials, it is necessary to clean up and stick to the pink body on the nozzle, the inner wall of the grinding cavity, and the graded wheel to prevent crushing and classifying effects. It is necessary to clean up the filter or replacement at the normal work of the pulse valve for 200 to 300 hours. Hierarchical motor bearing lubrication. When it runs for 2000 hours, it must be appropriately added with molybdenum grease, and the amount of oil should not be added too much, otherwise the bearing temperature will increase. 3. During the operation of the planetary material outlet, if the abnormal noise is found, the inspection should be performed immediately. Clean up the impeller and the body in the body every three months. Inject 00#polar pressure lithium base every three months. 4. The operating maintenance of the pulse bag dust collector's operating environment is poor. Check it every three months and clean the dust. Check the intact situation of the filter bag every six months and replace it. If the air outlet is ash, it should check whether the filter bag is separated and damaged. Whether the frame pressure plate is loose, whether the sealing ring is aging, and replace it. Pulse controller and solenoid valve can be checked normally before booting every day. 5. Control cabinet control cabinet pay attention to dustproof, close the door of the control cabinet tightly in use to prevent dust from entering. Clean up the dust with trachea every half a month to prevent poor contact. The above is the correct operation and maintenance method of the
