Summarize
SZX light linear screen utilizes vibration motor as the vibration source, so that the material is thrown up on the screen mesh, and at the same time moves forward in a straight line, and the material uniformly enters into the inlet of the screening machine from the feeder, and then produces several kinds of specifications of the upper and lower materials through the multi-layer screen, which are discharged from the respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully closed structure, no dust overflow, automatic discharge, more suitable for assembly line operation.
Feature
Stable and reliable, low consumption, low noise, long service life, stable vibration type, high screening efficiency, etc.
1. Good sealing, very little dust overflow.
2. Low energy consumption, low noise, long service life of screen mesh.
3. High screening precision, large capacity, simple structure.
4. Fully closed structure, automatic discharge, more suitable for assembly line operation.
5. All parts of the screen body are welded with steel plates and profiles (part of the group is connected by bolts), which makes the overall rigidity good, firm and reliable.
Working Principle
This sieve machine is mainly composed of sieve box, sieve frame, sieve mesh, vibration motor, motor pedestal, vibration damping spring, bracket and so on.
1, screen box: welded by several different thicknesses of steel plate, with a certain degree of strength and rigidity, is the main component of the sieve machine.
2, sieve frame: made of pine or small deformation amount of wood, mainly used to keep the screen flat, to achieve normal screening.
3, screen mesh: mild steel, brass, bronze, stainless steel wire and so on several kinds of screen mesh.
4, vibration motor (use and maintenance methods see vibration motor instruction manual).
5, motor pedestal: the installation of vibration motor, the use of the connection screws must be tightened, especially the new sieve machine three days before the trial, must be repeatedly tightened to avoid loosening caused by accidents.
6, vibration damping spring: to prevent vibration to the ground, while supporting the full weight of the screen box, installation, the spring must be vertical and the ground.
7, bracket: composed of four pillars and two channels, supporting the screen box, the installation of the pillar must be perpendicular to the ground, the two pillars below the channel should be parallel to each other.
Installation, commissioning and use
The equipment should be fixed on a special foundation, fixed by pre-embedded bolts. If a special foundation is not provided, anti-vibration rubber plates should be laid between the table and the machine base, and the machine must be equipped with a safe and reliable grounding protection wire before use.
Note: After the equipment is installed in place, the device used to fix the screen body and the machine base during transportation must be removed before starting the machine.
After the installation of the new sieve machine, it should be checked according to the following requirements:
1, check the insulation resistance of the vibrating motor winding to the ground, if <20MQ must be dried before use.
2, sieve body and seat on the upper and lower spring seat ring, the spring should be completely vertical embedded in the spring seat ring to ensure the balance of the sieve body, the vibration part of the sieve machine Do not have any hard connection or contact with other objects outside the machine.
3, close the power switch, confirm that the vibration motor synchronous reverse rotation, 10-20 minutes of idling, equipment in the operation of any abnormal sound, should be quickly shut down to check and deal with. After the normal operation of the equipment, a small amount of material to be screened can be put into the sieve machine through the inlet to confirm that the material travels in the direction of the outlet, and then gradually increase the amount of feed to the required and can withstand.
4, When screening materials, the materials should be put into the sieve evenly at the feeding port to ensure that the materials on the sieve surface are evenly distributed. When the material falls, there should not be a big impact, so as not to damage the screen mesh, under special circumstances (such as the material particle size difference, the material than the large, etc.) should be added to the feed mouth of a layer of thicker screen as a buffer.
5, the user can according to the number of layers of the sieve machine, the specific gravity of the material is different to increase or decrease the vibration force of the sieve machine (by adjusting the angle of the eccentric hammer at both ends of the vibration motor to increase or decrease the vibration force), so as to make the sieve machine to achieve the best sieving effect.
6, equipment in the downtime to produce a momentary resonance area, the amplitude and noise will increase significantly, is a normal phenomenon, the equipment in the opening and stopping before the sieve surface shall not be stored materials, screen mesh need to be frequently checked whether the tension, broken, if broken, to be replaced immediately.
