Abstract
The utility model relates to a double-mass vibrating screen. The front part of the double-mass vibrating screen is provided with a feed end, the rear part of the double-mass vibrating screen is provided with a discharge end, and a screen plate is arranged at the position being adjacent to the feed end. The double-mass vibrating screen is of a double-mass design, wherein one of two masses is a vibrating slot at the lower part of the vibrating screen, and the other mass is an exciter at the upper part of the vibrating screen. A set of excitation springs is connected between the vibrating slot and the exciter. A vibrating motor is arranged on the exciter, and the vibrating slot is provided with a rib plate. The whole vibrating screen is arranged on a support through a vibration attenuation spring arranged at the side part or the bottom part of the vibrating screen. According to the double-mass vibrating screen, a double-mass design principle is adopted, and the other mass vibrating slot is driven by one mass exciter. The excitation springs are connected with the two masses to form an effective subresonance system. The double-mass vibrating screen is capable of increasing the running efficiency of equipment and reducing maintenance amount and is suitable for various large-scale and extra large-scale industrial applications.
Description
Technical field
The utility model relates to vibrating machine, is specifically related to a kind of vibratory sieve that is applicable to aspects such as bulk material sorting, screening, belongs to International Classification of Patents B07B technical field.
Background technology:
Existing traditional vibratory sieve is the elemental body vibratory sieve on the market, and its mass of vibration and exciting force are contradictory relations: the exciting force of the big needs of mass of vibration is big, and exciting force greatly then requires to increase structural member thickness guaranteeing intensity, thereby causes mass of vibration to increase.Because the mass of vibration increase requires exciting force to increase conversely, this contradictory relation makes the elemental body vibratory sieve can not design very effectively, thereby has caused problems such as this type of vibratory sieve running efficiency is low, maintenance is big, energy consumption height.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of double-mass vibrating sieve that improves operation rate, cuts down the consumption of energy is provided.
The purpose of the utility model realizes through following technical scheme.
A kind of double-mass vibrating sieve, the front portion is a feed end, the rear portion is a discharge end, with the feed end adjoiner sieve plate is housed; Vibratory sieve adopts two plastid designs, and a plastid is the groove that shakes of vibratory sieve bottom, and another plastid is the vibrator on vibratory sieve top, shakes to be connected with one group of exciting vibration spring between groove and the vibrator; Vibrating motor is installed on the vibrator, on the groove that shakes, gusset is installed.Vibratory sieve integral body is installed in the support through the shock-absorbing spring of its sidepiece or bottom installing.
Problems such as the utility model is lower to vibratory sieve running efficiency in the prior art, the need maintenance is big, energy consumption height provide a kind of double-mass vibrating sieve.Can improve the running efficiency of equipment, reduce maintenance, cut down the consumption of energy.
Description of drawings
Accompanying drawing is the structural representation of the utility model double-mass vibrating sieve.
Among the figure: 1. vibrating motor, 2. vibrator, 3. exciting vibration spring, the groove that 4. shakes, 5. feed end, 6. sieve plate, 7. discharge end, 8. shock-absorbing spring 9. supports, 10. gusset.
The specific embodiment
Referring to accompanying drawing, there is feed end 5 front portion of double-mass vibrating sieve, and there is discharge end 7 at the rear portion, with the adjacent to of feed end 5 sieve plate 6 is housed.The utility model has adopted two plastid designs, and the parenchyma body is the groove 4 that shakes of vibratory sieve bottom, and another plastid is the vibrator 2 on top, and the parenchyma body shakes and is connected with one group of exciting vibration spring 3 between groove 4 and another plastid vibrator 2; Two vibrating motors 1 are installed on the vibrator 2.The sidepiece of groove 4 that shakes, and support 9 between shock-absorbing spring 8 is installed.
The utility model has adopted two plastid design principles, adopts a plastid (vibrator 2) to drive another plastid (groove 4 shakes).Vibrating motor 1 is arranged on the vibrator 2, and the groove 4 that shakes is connected with one group of spring---exciting vibration spring 3, and exciting vibration spring 3 has connected two above-mentioned plastids, has formed an effective subresonance system.Excited frequency with subresonance system equipment is slightly less than the intrinsic frequency of vibrational system.When vibrating motor 1 work, the exciting force that is produced makes mass vibrating, and vibrator 2 makes parenchyma body---groove 4 vibrations of shaking through exciting vibration spring.The eccentricity excitation power that is produced by vibrating motor 1 drives vibrator 2, and the amplitude of vibrator 2 amplifies through exciting vibration spring 3, thereby produces the groove 4 desired effective amplitudes that shake.Material gets into from feed end 5, is dispersed on the sieve plate 6, and is delivered to discharge end 7 through vibration, and material is sized in the process of carrying.The vibration that the groove 4 that shakes is produced is isolated by shock-absorbing spring 8 effectively, thereby vibration can not be propagated on the ground, avoids causing the influence to the vibratory sieve surrounding enviroment.
