The straight vibrating screen, also known as the straight vibrating screen, is a screening equipment with simple structure, large output and simple operation. It can be widely used in food, medicine, chemical industry, metal metallurgy, building materials, instant noodles, noodles, snacks, solid drinks and other industries. It is an indispensable screening equipment in the particle and powder industries today to separate foreign matters in raw materials (flour, starch, milk powder, additives, etc.), Driven by two horizontal vibration motors, the screen frame moves forward and upward to achieve the screening and impurity removal of materials.
Straight row sieve
The excitation force for the operation of the linear vibrating screen comes from two vibration motors fixed on the screen box. When they rotate together in opposite directions, the eccentric blocks on the vibration motor will generate centrifugal force at every position and moment of rotation to move back and forth along the throwing direction. The entire screen machine is supported by force on the shock absorber to continuously generate linear vibration, and the materials on the screen surface will also be thrown forward and jump forward to make linear motion, Thus, the entire screening operation is completed through loose sieving.
Characteristics of straight row vibrating screen:
1. The space occupation is small, and the motor is designed on the outside of the equipment, reducing the height of the equipment and making effective use of the space; The equipment is easy to operate and has a large obtuse angle that is easy to clean;
2. Simple structure, easy to repair and maintain;
3. Low working noise, ultra-low silent design;
4. The sealing effect of the equipment is good, and dust is difficult to escape;
5. Convenient disassembly and assembly, easy to clean inside and outside, no sanitary dead spots, in compliance with food grade and GMP standards and specifications;
6. The output of impurity removal is large, and the inlet and outlet are designed in the same vertical direction. The finished products under the screen quickly pass through the screen, reducing the retention time of materials on the screen surface and significantly improving the screening output.
Disadvantages of direct screening:
1. Prone to abnormal or non operating faults of the motor; Check if the power supply is out of phase or powered off, check if the socket has poor contact, check if the motor coil is burnt out, if too much lubricating oil is injected, or if the bearings are severely worn;
2. The sealing element is damaged quickly; Observe whether the bundle ring is locked tightly, tighten the bundle ring bolts, if there are signs of movement, tighten the bundle ring bolts, and if the material has temperature, replace the sealing element with a high-temperature resistant sealing material;
3. The sieve is easily damaged; If the screen is not tightened, replace and adjust the screen. If the feeding is uneven, change the feeding method or install a distributor. If there is a large amount of feeding in an instant, change the feeding method or install a distributor. If there are foreign objects in the material, pay attention to the control of the previous process.
