In description of the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand above-mentioned term concrete meaning in the present invention.
Below with reference to Fig. 1-Fig. 3, describe according to the filter 100 of the embodiment of the present invention.This filter 100 can be used for separation industries and produces the impurity in aluminium oxide.Certainly, the present invention is not limited to this.As shown in Figure 1, this filter 100 comprises: mounting bracket 10, sieve 20 and for vibrating the vibrating motor 50 of sieve 20.
Particularly, mounting bracket 10 is provided with charging aperture 11, discharging opening 12 and slag notch 13.Sieve 20 is located in mounting bracket 10 and by mounting bracket 10 internal insulation become to be positioned at sieve 20 upper chamber 30 above and be positioned at sieve 20 lower chambers 40 below, wherein, charging aperture 11 and slag notch 13 are communicated with upper chamber 30 respectively, and discharging opening 12 is communicated with lower chambers 40.That is to say, the material that contains aluminium oxide enters in upper chamber 30 from charging aperture 11, under the effect of vibrating motor 50, sieve 20 up-down vibration, wherein, the alumina particle that particle diameter is less falls in lower chambers 40 from the upper surface of sieve 20, and flows out from discharging opening 12, enters the production and processing technology of next stage; The impurity particle that particle diameter is larger cannot pass sieve 20, is transferred out slag notch 13 and flows out from slag notch 13, thereby realizing the object that alumina particle separates with impurity particle.
As shown in Figures 2 and 3, sieve 20 comprises: bottom screen cloth 21, sieve support 22, middle level screen cloth 23 and top layer screen cloth 24.
Particularly, sieve support 22 is located on bottom screen cloth 21, and sieve support 22 is latticed.Middle level screen cloth 23 is located on sieve support 22.Top layer screen cloth 24 is located on the upper surface of middle level screen cloth 23, and wherein the screen-aperture of middle level screen cloth 23 is greater than the screen-aperture of top layer screen cloth 24, and the aperture of the sieve aperture of bottom screen cloth 21 is greater than the screen-aperture of top layer screen cloth 24.Like this, the alumina particle that particle diameter is less can pass the less top layer screen cloth 24 in aperture, and falls in lower chambers 40, flows out from discharging opening 12 production and processing technology that enters next stage; The impurity particle that particle diameter is larger cannot pass the less top layer screen cloth 24 in aperture, can only flow out from slag notch 13.
Alternatively, the sealike colour of formation middle level screen cloth 23 is greater than the diameter of the netting twine that forms top layer screen cloth 24.Thus, middle level screen cloth 23 can play effective supporting role to top layer screen cloth 24, has extended 20 service lifes of top layer sieve.
Inventor is surprised to find that, compared with prior art, by bottom screen cloth 21, middle level screen cloth 23, top layer screen cloth 24 and sieve support 22 are located in mounting bracket 10 as an overall structure, improved more than 5 times the service life of sieve 20.In addition, if sieve 20 goes wrong, sieve 20 can unload easily in mounting bracket 10, changes in time or keeps in repair, and assurance alumina producing processing technology is moved long-term effectively.
According to the sieve 20 of the embodiment of the present invention, by multilayer screen cloth is arranged on sieve support 22, it is more convenient to have improved the service life of sieve 20 and sieve 20 is used.
In some embodiments of the invention, in each grid of sieve support 22, can be provided with at least one spheroid 25.Wherein, spheroid 25 can be between middle level screen cloth 23 and bottom screen cloth 21 bob.Under the shock of spheroid 25, the material that can make upper chamber 30 contain aluminium oxide spreads out as soon as possible.Thus, can accelerate the separating rate between alumina particle and impurity particle, what make that alumina particle separates with impurity particle is more thorough.For example, spheroid 25 can be round log ball.The light good springiness of round log ball quality, only need less external force just can be in grid bob, and not can with alumina particle generation chemical reaction.
Alternatively, sieve support 22 comprises orthogonal multiple the first dividing plates 26 and multiple second partition 27.Wherein, multiple the first dividing plates 26 are parallel to each other and spaced apart, and multiple second partitions 27 are parallel to each other and spaced apart.For example, as shown in Figure 2, multiple the first dividing plates 26 are spaced apart along left and right directions, and multiple second partitions 27 are spaced apart along fore-and-aft direction.Wherein, multiple the first dividing plates 26 can be equidistantly to distribute, and multiple the second shelves 27 can be also equidistantly to distribute, further, distance between distance and two second partitions 27 of arbitrary neighborhood between two the first dividing plates 26 of arbitrary neighborhood can equate, also can not wait.Alternatively, multiple the first dividing plates 26 can the side's of being hardwood with multiple second partitions 27.Side's hardwood has good non-oxidizability and corrosion resistance, and lighter weight, is convenient to vibrating motor 50 and drives it to move up and down.
In other embodiment of the present invention, sieve 20 is horizontally set in mounting bracket 10.On mounting bracket 10, be also provided with the observation panel communicating with upper chamber 30, and filter 100 also comprises the transparent windows 60 of the opening door that is located at observation panel place.Like this, producers can clearly observe the separation, impurity removal situation in filter 100, and can clear up in time impurity or the soft shape thing of the larger particles that can not flow out from slag notch 13.Wherein, slag notch 13 and discharging opening 12 are positioned at a side of mounting bracket 10, observation panel be positioned at discharging opening 12 directly over.Thus, convenient producers monitor the material in filter 100.
In some embodiment more of the present invention, discharging opening 12 comprises linkage section 121 and outlet section 122, and the import of linkage section 121 is connected with mounting bracket 10, and the outlet of linkage section 121 is connected with outlet section 122.Linkage section 121 is configured to narrow gradually towards the outlet of linkage section 121 from the import of linkage section 121, and the width of outlet section 122 can be identical with the exit width of linkage section 121.That is to say, the bore of the import of linkage section 121 is greater than the bore of the outlet of linkage section 121.Wherein, as shown in Figure 1, the cross section of linkage section 121 can be right-angled trapezium, and the horizontal range L1 of the upper end of the hypotenuse of right-angled trapezium and charging aperture 11 is less than the lower end of hypotenuse and the horizontal range L2 of charging aperture 11 of right-angled trapezium.Thus, can shorten aluminium oxide after filtration in the time of staying of lower chambers 40, accelerate discharging speed, increase the disposal ability of filter 100.
It is worth mentioning that, inventor's discovery, by changing the structure of discharging opening 12, the ability that makes filter 100 process aluminium oxide has improved twice.
Owing to thering is long service life according to embodiment of the present invention sieve 20, the advantage that separation, impurity removal is respond well.Therefore, there is long service life according to the filter 100 of the embodiment of the present invention, the effective and large advantage for the treatment of capacity of separation, impurity removal.
