Electric filter use precautions and common troubleshooting

DSX type electric filter is a kind of professional equipment developed and produced according to the GB5494-85 "Food Oil Inspection Impurity, Imperfect Granule Inspection" national standard. After the equipment is matched with the grain selection sieve, it is widely applicable to the screening and determination of grain and oil, and is the necessary screening and grading equipment for agricultural breeding. DSX type electric filter belongs to the computer filter and is widely used for the screening and determination of grain and oil. It is a necessary screening and classification equipment for agricultural breeding. In addition, there is a grain filter, which is a kind of inspection instrument for checking the impurity content of granular grain and oil samples, and the content of rice and wolfberry powder in rice and determining the quality grade of the grain.

The computer filter adopts a desktop structure, which is driven by a worm gear and a gearbox. The screen body is supported by a three-point plane and is rotated by an eccentric linkage mechanism. In the electronic control part, the 89LE52 single-chip microcomputer is used to control the forward rotation and the reverse rotation, the controlled forward and reverse rotation time has high precision, the program performance is reliable, and the power can be repeatedly turned off without shutting off the power supply.

During the use of the electric filter, attention should be paid to the following issues: 1. The instrument should be placed on a hard and dry working surface in a dry and ventilated laboratory to prevent shaking during operation. 2. After the sample is placed on the screen cover, the lever must be tightened so that the screen layer can be placed on the tray smoothly and then press the start button. Do not press the start button until the lever is tightened or the lever is not removed. . 3. Always pay attention to the set screws at both ends of the three connecting rods (schematic-6) to prevent loosening and vibration and noise. 4. When the three-link linkage is displaced and the tray jams, check whether the six screws at both ends of the three-bar linkage are loose and adjust one by one. 5. When the gearbox is stuck, send the 4 screws in the middle of the tray and the 3 screws on the outer end of the connecting rod to adjust the gearbox.
