Abstract

The utility model discloses a vibration screener, which comprises a screen frame (1), a lock catch (2), a vibration bucket (3), a machine base protecting cover (6), a vibration motor (8), a spring (9) and a machine base (11), wherein the upper horizontal plane and the lower horizontal plane of the vibration motor (8) are respectively connected with an upper heavy hammer (5) and a lower heavy hammer (10), and the vibration motor (8) is connected with a frequency converter (12). The upper heavy hammer (5) and the lower heavy hammer (10) are identical rectangular iron blocks, and the vertical included angle between the upper heavy hammer (5) and the lower heavy hammer (10) can be adjusted. Because the vertical included angle between the upper heavy hammer (5) and the lower heavy hammer (10) can be adjusted, the stressed part of the vibration bucket (3) is changed so as to impel materials in the screen frame (1) to move regularly; and because the frequency converter (12) is adopted to control the vibration motor (8), the amplitude and the excitation force can be adjusted according to different needs in order to improve screening precision and effect.

Description

A kind of vibrating screen classifier

Technical field

The utility model relates to a kind of screening plant, relates in particular to the vibrating screen classifier of a kind of different fineness filler and different viscosities auxiliary agent screening.

Background technology

Screening machine is the relative motion that utilizes bulk granular material and compass screen surface, makes the part particle see through sieve aperture, materials such as sand, gravel, rubble is divided into the vibration screening machinery equipment of different stage by granular size.

Vibratory sieve has eccentric gyration sieve, inertia vibrating screen and resonance screens etc., and its common feature is that compass screen surface is made high frequency, small amplitude motion, and the material on the compass screen surface is emanated, and can also sieve viscosity or moist material, is widely used.The amplitude of eccentric gyration sieve does not change with what of oversize material, is applicable to the first road scalping.Inertia vibrating screen single shaft arranged with twin shaft, the motion of its vibrational system is relevant with weight of material and spring rate, so the increase and decrease of material directly influences the amplitude size on the compass screen surface, is applicable to the occasion that feed amount and change of size are little, be usually used in second road screening of aggregate.The screen box of resonance screens is worked under resonance condition, but need only supply with the just continuous operation of energy that overcomes the screening kinetic damping, and power consumption is less, in being applicable to, bird's eye gravel material screen branch.

At present the vibrating screen classifier structure of using generally is made up of support, the ginseng two parts that shake, screening material running orbit in vibrating bucket is disorderly and unsystematic, require great effort when removing the bulky grain after sieving, and vibration frequency is non-adjustable, screening efficiency is low, and screen cloth easily stops up sometimes, vibrating motor fault rate height.

The utility model content

Technical problem to be solved in the utility model provides the vibrating screen classifier of a kind of screening precision height, efficient height, screening material regular motion.

For achieving the above object, a kind of vibrating screen classifier of the present utility model, comprise screen frame, snap close, vibration bucket, support protecting cover, vibrating motor, spring, support, its structural feature is: vibrating motor upper and lower end horizontal plane connects weight, lower heavy punch respectively, and vibrating motor connects frequency converter.

Last weight, lower heavy punch are same rectangle iron blocks, and iron block one end is equipped with the groove screw; Last weight and lower heavy punch are horizontally fixed on the vibrating motor upper and lower end horizontal plane with screw respectively, and screw head is set in the screw groove that heavily hangs down; Can regulate the vertical angle of weight, lower heavy punch.

Compared with prior art, the utlity model has following beneficial effect is:

1, owing to connect weight, lower heavy punch respectively at vibrating motor upper and lower end horizontal plane, and go up weight, the lower heavy punch vertical angle can be regulated, make vibration bucket force part change, thereby impel compass screen surface material regular motion;

2, owing to adopt the Frequency Converter Control vibrating motor, can regulate amplitude and exciting force, can regulate, improve screening precision and effect to reach according to different needs.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the structural representation of a kind of vibrating screen classifier of the utility model.

The specific embodiment

As shown in Figure 1, a kind of vibrating screen classifier of the present utility model, comprise screen frame 1, snap close 2, vibration bucket 3, support protecting cover 6, vibrating motor 8, spring 9, support 11, vibrating motor 8 upper and lower end horizontal planes connect weight 5, lower heavy punch 10 respectively, and vibrating motor 8 connects frequency converter 12.

Last weight 5, lower heavy punch 10 are same rectangle iron blocks, and iron block one end is equipped with the groove screw; Last weight 5, lower heavy punch 10 are horizontally fixed on the vibrating motor 8 upper and lower end horizontal planes with screw respectively, and screw head is set in the screw groove that heavily hangs down; Can regulate the vertical angle of weight 5, lower heavy punch 10.

The utility model is by lead 13 control vibrating motors 8 by frequency converter 12, vibrating motor 8 by spring 9 and set bolt 7 be fixed in the support 11, support 11 is connected support protecting cover 6, support protecting cover 6 connects vibration bucket 3, screen frame 1 is put into vibration bucket 3, screen frame 1 can require to install screen pack according to difference, and by snap close 2 screen frame 1 is fixed in the vibration bucket 3; The material that will sieve is packed in the screen frame 1, adjusts the vertical angle of weight 5, lower heavy punch 10, regulates frequency converter 12 by demand, Vibration on Start-up motor 8, last weight 5 upwards clashes into support protecting cover 6, and lower heavy punch 10 is bump support 11 bottoms downwards, thereby drives 3 vibrations of vibration bucket.Vibration bucket 3 amplitude vibrations according to demand, the material under the screening sifts out from discharging opening 4.

Regulate the vertical angle of weight 5, lower heavy punch 10 earlier, hold-down screw again, make vibration bucket 3 force parts change, material rotates, accumulates in screen frame 1 central part regular motion in the screen frame 1 thereby impel, and it is more convenient to remove the bulky grain that carries in the screen frame 1 like this; And owing to adopt frequency converter 12 control vibrating motors 8, can regulate amplitude and exciting force, improve screening precision and effect to reach according to different needs.
