Structure Description
The screening machine is mainly composed of screen box, screen frame, screen, vibration motor, motor pedestal, damping springs, brackets and other components.
1, screen box: the number of different thickness steel plates welded together, with a certain strength and stiffness, is a major component of the screening machine.
2, the screen frame: a small wood made ??of pine or the amount of deformation is mainly used to keep the screen flat, reaching the normal screening.
3, screen: low carbon steel, brass, bronze, stainless steel wire mesh and several kinds.
4, the vibration motor (use and maintenance methods are detailed in vibration motor manual).
5, the motor pedestal: Install vibration motor, connecting screws must be tightened before use, especially three days before the new trial screening machine, must repeatedly tightened to avoid loose causing the accident.
6, damping spring: to prevent vibration transmitted to the ground, while supporting the full weight of the sieve box, during installation, the spring must be perpendicular to the ground.
7, stents: the four pillars and two channel composition, supports screen box, when you install the pillars must be perpendicular to the ground, the two pillars of the following channels should be parallel to each other.
Production detail
Installation and use
The device should be fixed on a dedicated foundation, by embedded bolts. If you do not play special foundations, should be between the table and the equipment base laying anti-vibration rubber sheet before using the device must be configured to secure the grounding line of protection ..
Note: After installing the device in place, before starting the transport must be used to secure the base of the sieve and the device removed.
After installing the new screening machine, the following requirements shall be checked:
1, check the vibration motor winding insulation resistance to earth, before using if <20MΩ must be dried.
2, sieve and base unit, the lower spring retainer, spring should be completely vertical embedded spring retainer to ensure balanced sieve, vibrating sieve machine not part with any other object outside the machine rigid connection or contact.
3, close the power switch, make sure the vibration motor synchronous reverse rotation, air operation carried out for 10-20 minutes, the device at runtime if abnormal sound, should be checked promptly shut down process. After the device is working properly, can be a small amount of material to be sieved through the inlet into the screening machine set to confirm the material to the discharge port direction of travel, and then gradually increased to the desired feed rate can bear.
4, when the screening material, the inlet should be put into the material evenly to ensure uniform distribution of the material the screen surface. When the material whereabouts, not a big impact, so as not to damage the screen, under exceptional circumstances (such as material differences between the large particle size, material than the major, etc.) should be added in the feed opening as a buffer layer of coarse mesh.
5, the user can according to different layers, the material increase or decrease in proportion to the screening machine screen machine vibration force (by adjusting the angle between the eccentric weight at both ends of the vibration motor to increase or decrease the excitation force), the screening machine to achieve the best the screening effect.
6, the device generates an instant resonance region during downtime, in which case the amplitude and noise will be significantly increased, is a normal phenomenon, equipment downtime before the open, the screen surface may not have retained the material, screen often need to check whether the tension, damage , to be immediately replaced if damaged.
