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, connect integratedly, can be also to removably connect; Can be mechanical connection or electrical connection, can be also the connection of two element internals; Can be to be directly connected, also can indirectly be connected by intermediary, for the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Below with reference to accompanying drawing, the Horizontal pressure leaching reactor according to the embodiment of the present invention is described.
As Figure 1-3, the Horizontal pressure leaching reactor according to the embodiment of the present invention, comprising: kettle 100 and a plurality of shelf 200.
Specifically, a plurality of shelves 200 be all connected with the inwall of kettle 100 and adjacent two shelves, 200 interval preset distances so that kettle 100 is divided into a plurality of reative cells.Wherein, the top of each shelf 200 is provided with and makes the reaction mass overflow in reative cell described in upstream to the recess 2001 in the adjacent described reative cell in downstream.And a side of each shelf 200 adjacent reaction chamber, contiguous described downstream is provided with the guide shell 300 of accepting the reaction mass being overflowed by recess 2001.The upper edge of guide shell 300 (as shown in Figure 2) on above-below direction protrudes from the lower edge of recess 2001.
At this, it should be noted that, the height of a plurality of shelves 200 is stepped setting from high to low successively, so that reaction mass is interior mobile at kettle 100, this is understandable for those of ordinary skill in the art.
According to the Horizontal pressure leaching reactor of the embodiment of the present invention, a side at each connected reative cell in the contiguous described downstream of shelf 200 is provided with the guide shell 300 of accepting the reaction mass being overflowed by recess 2001, and the upper edge of guide shell 300 protrudes from the lower edge of recess 2001 on above-below direction.Thus, when the liquid level of the reaction mass of certain reative cell in kettle 100 is close to the recess 2001 of shelf 200, the effect of accepting due to guide shell 300, reaction mass can directly not overflow to contiguous downstream reaction chamber from recess 2001, but overflow to contiguous downstream reaction chamber from the upper edge of guide shell 300, extended the reaction time of reaction mass in this reative cell, thus, can make the reaction mass in reative cell described in each mix, improved the leaching rate of ore pulp material, improved production efficiency and reduced production cost.
According to one embodiment of present invention, guide shell 300 is rectangular guiding cylinder.Alternatively, according to some embodiments of the present invention, guide shell 300 is half-cylindrical guide shell.Certainly, the cross section of guide shell 300 can be also triangle.Above embodiment for the person of ordinary skill of the art, is the selection of some routines, does not repeat them here.
Advantageously, according to an example of the present invention, as shown in Figure 2, guide shell 300 can be integrally formed with shelf 200.Thus, can make according to the Horizontal pressure leaching reactor of the embodiment of the present invention easy for installation.
Advantageously, according to a concrete example of the present invention, the guide shell of guide shell for being made by TA2.Thus, can make guide shell 300 adapt to the wet method refining to metals such as zinc.
Further, according to examples more of the present invention, guide shell 300 can be welded on shelf 200.Thus, can further make according to the Horizontal pressure leaching reactor of the embodiment of the present invention easy for installation.
Further, according to one embodiment of present invention, the bottom interval 10-20cm of the diapire of guide shell 300 and kettle 100.Thus, can make reaction mass more fully react.Certainly, the concrete size of guide shell 300, such as length etc., can determine according to the actual flow of the volume of kettle 100 and reaction mass, does not repeat them here.
According to some embodiments of the present invention, as shown in Figure 1, described Horizontal pressure leaching reactor also comprises a plurality of agitators 400, a plurality of agitator 400 correspondences be located at described a plurality of indoor so that reaction mass is stirred.Thus, can be that reaction mass more fully reacts.
Below simply describe according to the use procedure of the Horizontal pressure leaching reactor of the embodiment of the present invention.
Reaction mass pumps into the first reative cell (being positioned at as shown in Figure 1 the reative cell of the top) with force (forcing) pump after pulp, when the liquid level of reaction mass approaches the recess 2001 of shelf 200, the reaction mass in 400 pairs of the first reative cells of turn on agitator stirs.Reaction mass under agitation overflows and enters in guide shell 300 from recess 2001 gradually.Because guide shell 300 has been accepted the reaction mass overflowing from recess 2001 and can not have been made this partial reaction material enter the second reative cell being connected with the first reative cell, extended the reaction time of reaction mass, can make reaction mass fully react.After the interior reaction mass of guide shell 300 is accumulated to a certain degree, reaction mass overflows and flows in the second reative cell from the upper edge of guide shell 300.
According to the Horizontal pressure leaching reactor of the embodiment of the present invention, can guarantee the leaching rate of reaction mass, thereby improve the rate of recovery of metal, can enhance productivity, lower production cost.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiment or example.
