Abstract
The invention publishes a side-plate girder excitation water sieve, which belongs to the coal dressing plant dehydration equipment. It is mainly used in end of the refined coal dehydration, and also used in granule pea coal graduation. The girder is also used as side plate. Box-type vibration excitor is on the girder in transverse. The direction angle is adjustable. The spring of vibrations is pressed on girder. There is no usual support hollow beam and spring support. Therefore, it has low height, light quality, small driver power, simple structure and reliable operation.
Description
Technical field
The present invention relates to a kind of excitated dewatering screen of side plate girder, belong to cleaning unit.
Background technology
Current, adopt gear to force that the vibratory sieve of synchronous box vibrator to be adopted be in tilted layout mounting means on cross bearer of vibrator, to crossbeam and crossbeam and side plate to connect requirement very high, the whole height of sieve is bigger, and the pipe beam is more, and structure is loaded down with trivial details relatively, mass of vibration is big, and energy consumption is also high.
Summary of the invention
The present invention is directed to the problems referred to above, proposed a kind of new dewatering screen, it is little, simple in structure to have a whole height, little, the characteristic of low energy consumption of mass of vibration.
Technical scheme of the present invention is: a kind of excitated dewatering screen of side plate girder, comprise motor, flexible coupling, vibrator, power transmission shaft, screen box and vibration absorber, it is characterized in that: whole screen frame is surrounded by two parallel H shape longerons and four trapezoidal crossbeams, wherein four crossbeams are distributed on the longeron, each two down, longeron uses as the exciting beam simultaneously, it also is the side plate of screen frame, be provided with screen cloth in the screen frame bottom, be respectively equipped with two vibrator symmetric arrangement on longeron top, pass through propeller shaft couplings between two vibrators, power transmission shaft links to each other with motor by flexible coupling, thereby gives screen frame with transmission of power.Be provided with four groups of shock-absorbing springs in the longeron bottom, shock-absorbing spring is fixed on the spring fastening of bottom, is provided with water fender on the longeron at charging aperture place.
Its good effect is: whole screen frame is surrounded by two parallel H shape longerons and four trapezoidal crossbeams, and the exciting beam also is the screen frame side plate simultaneously, and whole height is very low, is greatly reducing than the common linear vibrating screen that is used for material dewatering aspect materials amount, the processing capacity; Simplifying greatly aspect the complex structure degree, greatly improving aspect bulk strength, the rigidity, thereby improving the dewatering screen reliability of operation, drive motor power also reduces.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples.
Fig. 1 is the front view of excitated dewatering screen of side plate girder:
Fig. 2 is the A-A view of excitated dewatering screen of side plate girder.
Among the figure: 1. side plate beam, 2. trapezoidal crossbeam, 3. screen cloth, 4. box vibrator, 5. water fender, 6. back screen cloth, 7. spring fastening, 8. shock-absorbing spring, a 9. vertical rack, 10. power transmission shaft, 11. flexible couplings, 12. motor, 13. motor framves.
The specific embodiment
As shown in Figure 1 and Figure 2, this sieve mainly is made up of two box vibrators 4 of motor frame 13, motor 12, shaft coupling 13, symmetric arrangement, power transmission shaft 10, screen frame and the vibration absorber of connection two vibrator output shafts.Screen frame by two H shape side plate beams of arranging along the sieve length direction 1, vertically prop up rack 9, two trapezoidal crossbeam 2, screen cloth 3 and back screen cloth 6 and water fenders of arranging up and down along the end cross direction 5 are formed; Side plate beam 1 is when side plate usefulness, and double as is installed the exciting beam of box vibrator 4 simultaneously.Shock-absorbing spring 8 is directly installed on below the side plate beam 1, does not have common stay pipe beam and upper bracket of the spring.For anti-the outer of sealing spatters, be provided with water fender 5 at the sieve feeding end.Described vibrator is the commercially available prod.
Sieve can have suitable negative incidence when installing, to improve dehydrating effect.
Suitably adjust the setting angle of two groups of eccentric blocks, vibrating direction angle is regulated between general 35 °～60 ° of requiring.
Claims (2)
1, a kind of excitated dewatering screen of side plate girder, it is by motor, flexible coupling, vibrator, power transmission shaft, screen box and vibration absorber are formed, it is characterized in that: whole screen frame is surrounded by two parallel H shape longerons and four trapezoidal crossbeams, wherein four crossbeams are distributed on the longeron, each two down, longeron uses as the exciting beam simultaneously, it also is the side plate of screen frame, be provided with screen cloth in the screen frame bottom, be respectively equipped with two vibrator symmetric arrangement on longeron top, pass through propeller shaft couplings between two vibrators, power transmission shaft links to each other with motor by flexible coupling, thereby gives screen frame with transmission of power; Be provided with four groups of shock-absorbing springs in the longeron bottom, shock-absorbing spring is fixed on the spring fastening of bottom, is provided with water fender on the longeron at charging aperture place.
2, excitated dewatering screen of side plate girder according to claim 1 is characterized in that: crossbeam is for respectively there being two or many up and down.
