By upper analysis, the utility model by arranging rapping rod below the grating of vibratory sieve, grating is carried out to lasting rapping and/or high pressure blow smelting operation, can increase the Oscillation Amplitude of grating, shake loose and/or dispel material, no matter whether have bulk materials, can guarantee not plug-hole, whereby, the utility model can reduce material plug-hole probability, improves screening efficiency.
Brief description of the drawings
Fig. 1 is the cross section view of vibration sieve plate preferred embodiment of the present utility model;
Fig. 2 is the longitudinal section cutaway view of vibration sieve plate preferred embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
For more directly perceived, vivid and succinct description the utility model, only the vibration sieve plate that comprises cleaning plant is described below, vibration sieve plate is described no longer separately.
As depicted in figs. 1 and 2, this vibration sieve plate preferred embodiment comprise grating 3, for side plate 1 and the rapping rod 2 of grating 3 are installed.Grating 3 is installed on the top of side plate 1 movably.The installation component of rapping rod 2 is installed on side plate 1 and is positioned at grating 3 belows.When application, rapping rod 2 is in the time following sieve plate vibration, and vibration that amplitude is larger can occur for it, thereby impacts grating 3.Visible, the distance outbalance between rapping rod 2 and grating 3, the distance between the two will ensure that rapping rod 2 is in the time that vibration sieve plate is worked, the boss 21 of rapping rod 2 can touch grating 3 to impact grating 3, thereby increases the amplitude of grating 3.For example, gap value between short column 23 hereinafter described and deep trouth 101, long column 24 and through hole 102 is 2～5mm, when guaranteeing that rapping rod 2 can automatically not drop out from side plate 1, rapping rod 2 can do with respect to grating 3 relative motion of 2～5mm, thereby impacts grating 3.
Particularly, as depicted in figs. 1 and 2, rapping rod 2 is column structure, its surface be provided with multiple protrusions for impacting the boss 21 of sieve plate grating 3 and for rapping rod 2 being installed on to the installation component of sieve plate grating 3 belows: short column 23, long column 24.On the side plate 1 of both sides, be respectively equipped with and embed the deep trouth 101 of short column 23, through the through hole 102 of long column 24, between short column 23 and deep trouth 101, long column 24 and through hole 102, it is matched in clearance, while making side plate 1 that vibration occur, can there is the play that amplitude is larger in rapping rod 2, to touch and to impact grating 3 thereupon.
The cross sectional shape of short column 23 and deep trouth 101, long column 24 and through hole 102 can be rectangle, circle or other shapes.Because the diameter of rapping rod 2 is greater than the diameter of deep trouth 101 and through hole 102, can play the spacing effect in left and right.Therefore, as long as guarantee to retain certain gap between short column 23 and deep trouth 101, long column 24 and through hole 102, as 2～5mm, guaranteeing that being convenient to rapping rod 2 in rapping rod can not drop out side plate does relative motion.In this preferred embodiment, the length of short column 23 and deep trouth 101 all can be lengthened to 2 times, even if mutual gap further increases (such as 10mm gap), rapping rod 2 also can not drop out from the slotted eye of side plate 1.
In order to increase the ramping effect of rapping rod 2, avoiding occurring on grating 3 material builds up and increases self clearing function of rapping rod 2, the hollow structure that preferably rapping rod 2 is column, and this hollow structure of rapping rod 2 inside is connected with an inlet channel (not shown).For simplified structure, this inlet channel is located at long column 24 inside; In addition, the sidewall of rapping rod 2 is provided with multiple pores 20, for the gases at high pressure (now rapping rod 2 can be called again high pressure rapping rod) of being inputted by inlet channel of jetting of the gap to grating 3.
More preferably, pore 20 and boss 21 stagger mutually, also, pore 20 are not set in boss 21, avoid boss 21 strength decreaseds.
The outer end 22 of long column 24 connects with the air inlet pipe 41 for being connected air pump, makes to be tightly connected to inlet channel and the air inlet pipe 41 of rapping rod 2 delivered inside gases at high pressure.Air inlet pipe 41 is provided with swivel joint 42, to avoid air inlet pipe 41 distortions.Preferably, air inlet pipe 41 is sebific duct.More preferably, long column 24 outer end 22 use lathe cars become valve shape, and valve is hangnail structure as shown in FIG., after air inlet pipe 41 is enclosed within the hangnail structure of outer end 22, utilize the elasticity of himself, air inlet pipe 41 can be fixed on the outer end 22 of long column 24, and guarantees to seal air tight.As an alternative, outer end 22 can be also Standard Gases mouth, is welded in long column 24, or links together by screw thread and long column 24 after buying from the market.
While applying this preferred embodiment, between short column 23 and deep trouth 101 due to rapping rod 2, leave certain interval between long column 24 and through hole 102, rapping rod can rely on the inertia of self, relative sieve nest play up and down in the time of shaker vibration.In the time of play upwards, the boss 21 in its outside carries out vibration beating to the grating 3 of top, and grating 3 is formed and impacted, and strengthens grating amplitude.Meanwhile, the source of the gas of connection is blown into gases at high pressure from the inlet channel of rapping rod 2 one end discontinuously, then outwards sprays by the pore 20 of vibrating head 2 surroundings, blows to the gap of grating 3, makes the material loosening of 3 of gratings, comes off, not plug-hole.Be interrupted the gases at high pressure that blow out and can also play the function that rapping rod 2 self is cleared up, prevent that moist coal dust is bonded at rapping rod 2 surroundings.
To sum up, the utlity model has following characteristics:
When shaker vibration, rapping rod can do with respect to sieve nest the play of certain amplitude and angle, and rapping rod outside is " mace " form, regular some boss that arrange of its outside surrounding, and when the upper and lower play of vibrating head, boss carries out vibration beating to top grating.
Vibrating head inside is hollow form, and its one end is provided with air admission hole, connects the source of the gas such as air pump, and surrounding is not that projection section is provided with some ventholes outside vibrating head, to surrounding winding-up gases at high pressure.
Visible, the utility model can utilize rapping rod to carry out lasting rapping and carry out discontinuously gases at high pressure winding-up screen cloth, increases screen cloth Oscillation Amplitude, even without the impact of bulk materials, still can guarantee not plug-hole, whereby, the utility model can reduce material plug-hole probability, improves screening efficiency.In the time that coal process field is tested, the utility model can perfectly solve the problem of the stifled sieve of material in Wet Coal ' particulate dry screening.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.Allly within the scope of the utility model or in the change being equal in scope of the present utility model, be all included in the utility model.
