Detailed description of the invention
As shown in Figure 1, the utility model mining energy-saving multi-stage oscillating screen comprises: be arranged on two groups of supporting legs on ground, often organizes supporting leg and has symmetrically arranged two supporting legs 9; Be arranged on the multistage sieve nest above supporting leg 9 with vibration isolation function, between multistage sieve nest, elasticity connects; Being arranged on the vibrator 1 above multistage sieve nest, making it that exciting force resonated occur for providing to multistage sieve nest.
The utility model utilizes multistage sieve nest generation resonance principle, and vibrator produces less exciting force just can sieve out the product coal of different grain size size, without the need to carrying out the process of vibration isolation again after exciting, not only reduces the exciting force to ground, and economize energy; The multistage sieve nest that the utility model adopts once just can sieve out multiple varigrained product coal, simplifies coal preparation technique and reduces capital construction area, reducing investment.
As shown in Figure 1, multistage sieve nest comprises: be fixedly mounted on three grades of fixing sieve nests 4 above supporting leg 9; Be arranged on the secondary be connected above three grades of fixing sieve nests 4 and with its elasticity and join the sieve nest 3 that shakes; Be arranged on secondary ginseng to shake above sieve nest 3 and the one-level be connected with its elasticity joins the sieve nest 2 that shakes; Wherein, vibrator 1 be arranged on one-level ginseng shake on sieve nest 2.
Wherein, the one-level ginseng sieve nest 2 that shakes is joined to shake between sieve nest 3 with secondary and is connected by two groups of leaf springs and two groups of rubber spring elasticity.Concrete, often organize leaf spring and have two leaf springs 7, the two ends of each leaf spring are joined respectively by spring carrying block 8 and one-level shake sieve nest 2 and secondary and are joined sieve nest 3 bolt that shakes and be connected; Often organize rubber spring and have four rubber springs 6, the two ends of each rubber spring 6 are joined respectively by rubber spring bearing 5 and one-level shake sieve nest 2 and secondary and are joined the sieve nest 3 that shakes and be connected.
Wherein, secondary ginseng is shaken between sieve nest 3 with three grades of fixing sieve nests 4 and is connected by two groups of leaf springs and two groups of rubber spring elasticity.Concrete, often organize leaf spring and have two leaf springs 7, the two ends of each leaf spring are joined respectively by spring carrying block 8 and secondary shake sieve nest 3 and three grades of fixing sieve nest 4 bolts and are connected; Often organize rubber spring and have four rubber springs 6, the two ends of each rubber spring 6 are joined respectively by rubber spring bearing 5 and secondary shake sieve nest 3 and three grades of fixing sieve nests 4 and are connected.
As shown in Figure 1, rubber spring bearing 5 correspondence is arranged on supporting leg 9, increases stability.
As shown in Figure 1, the direction of excitation of vibrator and the sieve plate direction setting at 45 ° of multistage sieve nest, make material fall into sieve plate after can jump to discharge end impelling with sieve plate direction at 45 °.
Operation principle of the present utility model is as follows:
Supporting leg 9 is connected with ground pre-embedded bolt by bolt in erecting bed, and three grades of fixing sieve nests 4 are connected with supporting leg 9 bolt by bearing; After vibrator 1 connects electricity, one-level is joined the sieve nest 2 that shakes and is produced vibration, by leaf spring 7 and rubber spring 6, vibration passing is joined the sieve nest 3 that shakes to secondary.
By regulating the parameter of rubber spring and the parameter of leaf spring, and it is identical with the second-order intrinsic frequency of machine system to set excited frequency, make one-level join the sieve nest that shakes join with secondary the vibrational state forming amplitude direction contrary (i.e. carrier phase shift π) between sieve nest that shakes and reach resonance effect, thus the less exciting force generation of realization is compared with the effect of large amplitude; In addition, because shake sieve nest and secondary of one-level ginseng is joined to shake between sieve nest and occurred oppositely to resonate, less to the exciting force of three grades of fixing sieve nests, therefore to the exciting force also corresponding reduction of ground.
The left upper end (shown in Fig. 1) that material joins from one-level the sieve nest 2 that shakes falls into, sieve through shake sieve nest 2 and the secondary ginseng sieve nest 3 that shakes of one-level ginseng successively, three grades of fixing sieve nests 4 accept the screenings (being mainly smalls) that secondary joins the sieve nest that shakes, by the mode of washing by water to the afterbody of three grades of fixing sieve nests, smalls is gone out discharge end (shown in Fig. 1 right-hand member).
Although above-mentioned, the utility model is elaborated; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
