Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

The utility model provides a novel double-frequency bidirectional sieve, for the multilayer design, the vibration source structure is little, and every section sieve core is driven by two solitary vibration exciters, and the position is adjustable in a flexible way about the vibration exciter, so the vibration direction angle of every section sieve core of it is adjustable, and the inclination of upper and lower floor's sifter is also adjustable, and it is better to handle different materials like this or select for use the different sieve the effect. The bearing chamber of each vibration exciter is arranged in the screen box and connected with the screen core, so that the required load is smaller, and the service life of the bearing is longer. The multilayer and multisection screen surfaces can be freely increased according to the requirement of the treatment capacity, and meanwhile, due to the multilayer bidirectional arrangement, the screening efficiency and the treatment capacity are greatly improved. The advantage that the vibrating screen box with the complex frequency screen core does not vibrate is also continued, the environmental protection performance is good, the energy consumption is low, the service life is long, and meanwhile, the joints of all the devices on the site are sealed by adopting soft connection, so that the dust is prevented from leaking.

The embodiment provides a complex frequency bidirectional sieve, as shown in fig. 1 and fig. 2, which mainly comprises two sets of sealing covers 8, a sieve core 2, a sieve box 1, a vibration exciter 3, a vibration damping spring 4, a feed inlet 5, a blanking hopper 6 and a motor 7, which are arranged oppositely.

The sieve box is characterized in that a plurality of sections of sieve cores 2 are arranged in the sieve box 1 which is gradually reduced from the middle part to two sides and is obliquely arranged at a preset inclination angle, each section of sieve core is driven by two independent vibration exciters 3, and the vibration exciters 3 are arranged on the lower parts of the vibration exciters 3. The damping spring 4 is driven by a motor 7 arranged on the motor bracket.

The two groups of sieve boxes are oppositely arranged, the middle is high, the two sides are low, and the sieve boxes are in a splayed shape. The inclination angle is adjusted as required.

The higher one end top of sieve case 1 sets up feed inlet 5, and feed inlet 5 is two-way feed inlet, feeds two sets of sieve case 1 respectively.

The upper end of the screen box 1 is provided with a sealing cover 8 for sealing the screen box 1.

The lower part of the screen box 1 is provided with a blanking hopper 6 for collecting materials under the screen. The blanking hoppers 6 are also respectively arranged for the two groups of sieve boxes 1. To the large granule material on each layer of core 2, also set up blanking fill respectively to collect the material respectively.

A plurality of sections of screen cores 2 arranged in the screen box 1 are arranged in an up-down layered manner or are arranged in a plurality of continuous sections according to inclination.

The up-down position of the vibration exciter 3 can be flexibly adjusted.

The screen box 1 does not participate in the vibration but the screen core 2 vibrates. The material is walked to two opposite directions through two-way feed inlet, and every section screen core 2 is driven by two sections solitary vibration exciters 3, and there are two sections or even multisection screen core 2 in every direction, and the frequency of shaking and the amplitude of every section screen core 2 can freely be adjusted, realizes the free regulation of high frequency low amplitude or low frequency high amplitude. The materials larger than the apertures of the sieve holes flow out of the sieve through the discharge hole of the sieve core 2, and the materials smaller than the apertures of the sieve holes fall to the lower side through the blanking hopper 6.

The working principle is as follows: two parallel rotating shafts which are far away from each other and have eccentric mass in a plane parallel to the material (screening surface) are dragged to rotate by two asynchronous motors. At the moment after the two motors are started, the two rotating shafts rotate through the screen body in a self-synchronizing mode, and linear vibration of the screen core is achieved. The vibrating screen body drives the screen plate to throw materials to move, and the materials pass through the screen holes in the falling process to achieve the purpose of material classification.
