Abstract
The utility model provides a vibration screen, which comprises a screen box provided with a feed inlet and a discharging port, a screen mesh arranged in the screen box, a vibration bracket arranged on the mesh box, a vibration device arranged on the vibration bracket, and a support rack used for supporting the screen box. The vibration screen is characterized in that the vibration device comprises at least two sets of vibration motors arranged in parallel with each other. Each set of vibration motors comprises two vibration motors in synchronous counter-rotating movements. Each vibration motor is provided with a transmission shaft. The transmission shafts of vibration motors arranged in different vibration motor units and rotating in the same direction are connected together through a shaft coupling. Due to the adoption of the vibration screen, the problem that a conventional vibration screen is small in output and low in screening precision is solved. According to the utility model, a plurality of sets of connected vibration motors in synchronous counter-rotating movements and a multi-layer screen mesh structure are adopted by the vibration screen, so that the driving force of the vibration screen is doubled and the screening area of the vibration screen is increased. Therefore, the screening efficiency and the screening precision are improved. The vibration screen also has the advantages of compact structure, safety, stability, low power consumption and good installation and maintenance.
Description
Technical field
The utility model relates to a kind of vibratory sieve, the large-scale vibrating screen that particularly uses in the dry powder and mortar field.
Background technology
Vibratory sieve is widely used in industries such as sandstone production line, metallurgy, colliery, ore dressing, building materials, in the bulk material treatment process, has extremely important status.In recent years, along with the fast development at home of dry-mixed mortar product, dry powder equipment is also towards intellectuality, and the maximization direction develops.Existing vibratory sieve output is lower, can not satisfy the demand that the client uses.But in the apparatus field of making dry-mixed mortar, sieve in order to be fit to superfine material; What mainly use is to disperse the drive-type probability screen; As use existing oscillating feeder because its discharging is concentrated; Cause cloth inequality, screen cloth to stop up easily, not only influence the operating efficiency of probability screen but also influence screening effect.
Summary of the invention
In order to address the above problem, the invention provides a kind of vibratory sieve, solved and be short of power, problem such as screening efficiency is low.
For this reason; The invention provides a kind of vibratory sieve; Comprise the screen box that is provided with charging aperture and discharging opening, be arranged at the inner screen cloth of screen box, be arranged at vibration rack on the screen box, be arranged at the vibrating device on the vibration rack; Be used to support the bracing frame of screen box, it is characterized in that: the vibrating motor group that said vibrating device laterally arranges at least two groups, said vibrating motor group are provided with two vibrating motors of counter-rotating synchronously; Vibrating motor is provided with power transmission shaft, and different vibrating motor groups turn to the power transmission shaft of identical vibrating motor to connect through shaft coupling.
Further, said shaft coupling is a tyre coupling.
Further, said screen box inwall is equipped with wearing plate.
Further, have the strip observation panel on the said screen box.
Further, the junction of support frame as described above and screen box is provided with damping spring.
The screen cloth of three layers of lateral tension further, is housed in the said screen box.
Further, every layer of screen cloth is to there being a discharging opening in the said screen box, and discharging opening is a monolithic construction.
The utlity model has following beneficial effect:
The vibratory sieve that provides according to the utility model; Problems such as existing vibratory sieve output is little, screening precision is low have been solved; Adopt the vibrating motor of the continuous synchronous counter-rotating of many groups and the structure of multilayer screen cloth; Make its driving force can be double, sieving area increases, and reaches the purpose that improves screening efficiency and screening precision, and compact integral structure, safety and firmness, power consumption is little, installation and maintenance property is good.

The specific embodiment
In order better to understand the technical scheme of the utility model, describe the novel embodiment that provides of this use in detail below in conjunction with accompanying drawing.
With reference to shown in Figure 1; A vibratory sieve as the utility model; Include screen box 1, vibration rack 2 and bracing frame 3, screen box 1 is provided with the observation panel 13 of charging aperture 11, discharging opening 12 and strip, and screen box 1 inside is provided with the screen cloth 14 of three layers of lateral tension; Each layer screen cloth 14 all is connected with a discharging opening 12, and the screen box inwall is equipped with wearing plate; Vibrate 2 supports and pass through bolt on screen box 1, vibration rack 2 is provided with vibrating device 3; Bracing frame 4 is fixed on the below of screen box, is provided with damping spring group 41 in the junction of bracing frame 4 and screen box.
With reference to Fig. 2,3, shown in 4; Said vibrating device 3 is two groups of vibrating motor groups that laterally arrange 31,32; Be respectively equipped with the vibrating motor 311,321 of forward and the vibrating motor 312,322 of anti-phase on the vibrating motor group 31,32; Vibrating motor is provided with power transmission shaft, and the power transmission shaft that is all the vibrating motor 311,321 of forward vibration connects through tyre coupling 33, and the power transmission shaft that is all the vibrating motor 312,322 of vibrate in opposite phase connects through tyre coupling 34.
The operation principle of this oscillating feeder is: under the cooperation of the driving of four vibrating motors 3 and damping spring 41; Screen box 1 straight-line oscillation; Material to be sieved gets into screen box 1 inside through charging aperture 11, successively sieves, and the material that screening is good is discharged through the discharging opening 12 that is connected with this layer screen cloth.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
