Abstract
The utility model discloses a rotary bioreactor, comprising a reaction tank, wherein bacteria liquid is filled into the reaction tank; a first water inlet and a first water outlet are arranged at the left end of the reaction tank; a second water outlet is arranged at the right end of the reaction tank; a roller is arranged inside the reaction tank; the roller is submerged into the bacteria liquid; the internal part of the roller is hollow; a hole is arranged on the roller; the aperture of the hole is smaller than that of a reaction material; a first reflux pipe is arranged inside the roller; and the hole is arranged on the reflux pipe. In this manner, the rotary bioreactor has the advantages of being less in pollution, mild in work condition, short in flow, low in cost, less in investment and the like, and has the characteristics of wide mineral applicability on application of mining metallurgical engineering; oxygen is provided to directly cultivate the bacteria liquid by rotation of the roller; the rotary bioreactor is convenient and rapid; the rotary bioreactor reacts in a manner of injecting the bacteria liquid; the damage to bacterial cells caused by shearing force of the stirring manner used in general is avoided; survival of the bacteria is facilitated, and the reaction of the rotation process of the rotary reactor is even.
Description
Technical field
The utility model relates to processes the old circuit board technical field, particularly relates to a kind of rotary bio-reactor that carries out committed step with microorganism.
Background technology
At present, be divided into following a few class for the treatment of the method for old wiring board (be called for short PCB): pyrometallurgy, hydrometallurgy, mechanical sorting facture, or by above-mentioned several method combination treatment.Pyrometallurgy and hydrometallurgy are mainly used in the recovery of the precious metals such as gold and silver, and its technique is simple, but cost is high, and secondary pollution is serious.The prerequisite of mechanical sorting facture is the separated necessary monomer dissociation of material, the method that reaches monomer dissociation is normally broken, in abandoned printed circuit board metal and nonmetal between combine by the technique such as film, by suitable equipment and breaking method, can make metal and nonmetal monomer dissociation.But wherein be that mode with alloy, coating or welding combines between the various metals, be difficult to make the metal monomer dissociation with Mechanical Crushing, so the mechanical sorting facture can only be used with other method as supplementary means.Above-mentioned several old wiring board facture is destructive strong, and technical process is complicated, causes cost of investment high, and use range also has limitation.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of rotary bio-reactor, comprise a reactive tank, bacterium liquid is housed in the reactive tank, the left end of reactive tank is provided with the first water-in and the first water outlet, the right-hand member of reactive tank is provided with the second water outlet, be provided with cylinder in the reactive tank, cylinder submerges in the bacterium liquid, the cylinder inner hollow, cylinder is provided with the hole, the aperture in hole is less than the reaction mass aperture, and cylinder inside is provided with a return line, and return line is provided with the hole.
Further, be provided with baffle plate in the reactive tank, prevent the material leakage, flow with bacterium liquid.
Further, cylinder is provided with 2.
The beneficial effects of the utility model are: have pollution less, gentle, the advantages such as flow process is short, cost is low, less investment of working conditions, and have the wide characteristics of mineral suitability in the application of mining metallurgical engineering, in the middle of the recovery in the unmanageable complicated ore of conventional art, low taste table Tu Kuang, discarded ore deposit etc., have unique advantage; The bacterium liquid that rotates to be by cylinder provides oxygen directly to cultivate bacterium liquid, and is convenient and swift; Rotary reactor reacts by the mode that bacterium liquid is injected, and has avoided the shearing force of common used alr mode to the damage that bacterial cell causes, and is conducive to the survival of bacterium; Rotary reactor rotation process reaction evenly can not cause soon Cu2+ concentration to raise because of certain partial reaction, thereby bacterium is exerted an influence; Rotary reactor easy accessibility is conducive to load the PCB powder, also convenient taking-up after reaction is finished.
Description of drawings
Fig. 1 is the perspective view of rotary bio-reactor one preferred embodiment of the utility model.
The mark of each parts is as follows in the accompanying drawing: 1, reactive tank; 2, the first water-in; 3, the first water outlet 4, the second water outlet; 5, cylinder; 6, return line; 7, baffle plate.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of rotary bio-reactor, comprise a reactive tank 1, bacterium liquid is housed in the reactive tank 1, the left end of reactive tank 1 is provided with the first water-in 2 and the first water outlet 3, the right-hand member of reactive tank 1 is provided with the second water outlet 4, be provided with cylinder 5 in the reactive tank 1, in cylinder 1 half bacterium liquid that submerges, cylinder 5 inner hollow can be added reaction mass, and cylinder 5 is provided with the hole, in the process of rollers roll, oxygen is brought into the reactive tank that fills bacterium liquid, the aperture in hole is less than the reaction mass aperture, and to guarantee that reaction mass can not drop out cylinder, cylinder 1 inside is provided with a return line 6, return line 6 is provided with the hole, cultured bacterium liquid can be passed in the return line 6, bacterium liquid enters with it reaction in the cylinder that reaction mass is housed by the hole on the return line 6, and the orifice flow that sees through on the cylinder 1 after the reaction enters in the reactive tank 1, bacterium liquid in the groove again passes in the return line and reacts with reaction mass, successively repeatedly; Be provided with baffle plate 6 in the reactive tank 1, prevent the material leakage, flow with bacterium liquid; Preferred forms is that cylinder 1 is provided with 2.
The utility model bacteria used thereby liquid is that the bacterial classification of thiobacillus ferrooxidant is made, and at first craft or Mechanical Crushing wiring board screen with 45 order national standard analyses sieve after high speed disintegrator is pulverized again.Get undersized product, dried 1 hour for 105 ℃.Hit the crushed products that obtains diameter 0.2mm-0.28mm after the formula riddler is processed with 60 orders and 75 order national standard analyses sieve and top again.Further, the PCB powder filled out pour into cylinder, and be closed; Further, cultured Bacteria liquid is packed in the groove, this moment half cylinder bacterium liquid that submerges, with pump bacterium liquid is squeezed into the middle return line of cylinder, this moment, bacterium liquid namely reacted with the PCB powder, and the bacterium liquid that reacted is got back in the groove again, start at last cylinder, allow cylinder in bacterium liquid, rotate.Therefore, the technical program is combined mechanical treatment with microbiological treatment, and is first that PCB is broken, and recycling is processed by microorganism.Copper among the PCB is reclaimed.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
