Description
Technical field
The utility model relates to a kind of mechanical device, particularly relates to a kind of vibrating screen device of dryer.
Background technology
Traditional vibratory sieve is in carrying out the material particles screening process, and screen cloth often adopts the braided steel wire net or adopts steel plate towards circular hole, and screen cloth adopts press strip, bolt and sieve nest directly fixing, and vibration frequency is constant.Along with the growth of operation hours, screen cloth is through material bump, and screen cloth deforms, clogging, has a strong impact on sieve performance, makes the material screening quality can not reach technological requirement, in the short time vibratory sieve lose stable, sieve function accurately; Simultaneously, the frequent stage of development property variation of mass flow because the shaker vibration frequency can not be regulated, causes the material screening quality to fluctuate.This makes traditional vibratory sieve stability, poor accuracy, can not satisfy the material particles screening requirement that present mouthful of benefit increases.This makes traditional vibratory sieve maintenance and repair frequent, and operating cost is high.Up to the present, also there are not the good substitute products of performance to occur.
The utility model content
The technical problem that the utility model solved is to provide a kind of vibrating screen device of dryer, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of vibrating screen device of dryer comprises support, vibration sieve nest, tensioning apparatus, screen cloth and vibrator.The vibration sieve nest is installed on above-mentioned support; Screen cloth is installed on above-mentioned vibration sieve nest through tensioning apparatus; Vibrator connects above-mentioned screen cloth.Hole on the wherein above-mentioned screen cloth is the strip hole, and the material movement direction is vertical with strip hole length direction.
In the utility model, vibratory sieve also comprises the control system, is electrically connected above-mentioned vibrator, and what control optimum system choosing is frequency-changing control system.
In the wood utility model, vibratory sieve also comprises suspension apparatus, is installed between support and the vibration sieve nest.
Further, vibratory sieve also comprises maintenance door closure and Waste gas outlet, all is installed on the vibration sieve nest.
The utility model can change the vibration frequency of in good time adjusting vibrator within the specific limits according to mass flow; Make the material screening quality keep certain stability like this; Reduce its fluctuating range greatly, improved the accuracy of screening, satisfied present growing material particles screening requirement.

Fig. 1 is the front view of the utility model one embodiment.
Fig. 2 is the vertical view of vibratory sieve among Fig. 1.
Fig. 3 is the schematic internal view of vibration sieve nest among Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Please be simultaneously referring to figs. 1 to Fig. 3, the utility model comprises support 1, vibration sieve nest 2, tensioning apparatus 4, screen cloth 3 and vibrator 5.Vibration sieve nest 2 is installed on support 1.Screen cloth 3 is installed on vibration sieve nest 2 through tensioning apparatus 4.Vibrator 5 connects vibration sieve nest 2.Among the wood embodiment, tensioning apparatus 4 can be the adjustment screw, also can be other adjustable tightening members, and the utility model does not add any restriction to this.
In the present embodiment, vibratory sieve also comprises control system 7, is electrically connected vibrator 5.Further, control system 7 is frequency-changing control systems.Wherein, the concrete element of frequency-changing control system and vibrator 5 and operation principle have in this area and belong to common practise the people of common knowledge, repeat no more at this.
In the utility model, vibratory sieve also comprises suspension apparatus 6, is installed between support 1 and the vibration sieve nest 2.Suspension apparatus 6 can be made up of spring, steel wire rope, spring fastening protection box, adjusting screw(rod), securing member, and for the people who has common knowledge in this area, the structure of suspension apparatus 6 belongs to common practise, gives unnecessary details for a short time at this again.
In the present embodiment, vibratory sieve also comprises maintenance door closure 8, is installed on the vibration sieve nest 2, when break down in vibration sieve nest 2 inside, opens maintenance door closure 8 and can carry out maintenance work.
In the present embodiment, vibratory sieve also comprises Waste gas outlet 9, is installed on the vibration sieve nest 2, and produce discarded that bump during the material particles vibration can be discharged through Waste gas outlet 9.
In the utility model, screen cloth 3 adopts 304 thick corrosion resistant plate punchings of lmm to make, and hole H wherein is the strip hole, and the material movement direction in the vibratory sieve is vertical with strip hole H length direction.
The utility model when mounted; The tensioning apparatus 4 that is arranged in vibration sieve nest 2 both sides is screen cloth 3 expansions of tile fully, again through fastening standard component and vibrate sieve nest and fix, when concrete operations; Material particles gets into vibration sieve nest 2 from the A mouth; The direction of motion of material particles is vertical with strip hole H length direction, and the material particles that meets granularity requirements after the screening is collected through C mouth and powder bucket 10, and the material particles that does not meet granularity requirements will advance the outflow of B mouth.
In sum, because screen cloth is installed on the vibration sieve nest via tensioning apparatus, when vibratory sieve operated, the vibration frequency of screen cloth was variable like this.And the control system adjusts the vibration frequency of vibrator automatically in good time according to the changes in flow rate of material particles; Can prevent effectively that like this screen cloth from deforming, preventing that screen cloth from stopping up; Make the screening quality of material particles keep certain stability; Reduce its fluctuating range greatly, and the utility model need not artificial frequent to intervene, easy to use, and can effectively prolong service life of equipment.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
