Abstract
The utility model relates to a separation cavity of an interdigital electrode dielectrophoresis separation system. The separation cavity consists of a separation cavity body and an interdigital electrode, wherein the interdigital electrode consists of a plurality of insulation wires; the separation cavity body is cylindrical; and the interdigital electrode is in coaxial clearance fit with the inner edge of the separation cavity body and consists of a positive electrode insulation wire group and a negative electrode insulation wire group which have different heights and are arranged at an interval. By the cylindrical separation cavity, materials can be effectively saved, and inner pressure is reduced; due to the shape of the cylindrical separation cavity, an electric field is uniformly distributed, and separation dead angles are reduced, so that the highest separation efficiency can be achieved; furthermore, due to the shape of the cylindrical separation cavity, electric breakdown and short circuit of the electrode and a power supply, which are caused by partial overhigh voltage and partial overhigh current, are avoided; by a flange connection mode, the separation cavity is conveniently connected with components at an input section and an output section of a noble metal dielectrophoresis system; a phenomenon of short circuit possibly caused by a reason that the separation cavity is closely connected with the power supply is avoided to the maximum extent; and a phenomenon that noble metal is stacked at the bottom and difficult to collect is avoided.
Description
Technical field
The utility model belongs to separation technology field, relates to the noble metal separation and Extraction of the precious metal minerals such as gold, especially a kind of disengagement chamber that reclaims the interdigital electrode dielectrophoresis separation system of precious metal.
Background technology
Although the technology of dielectrophoresis is defined and proposes more than 30 years, many dielectrophoresises are also fast-developing in application biological and medically.But all dielectrophoresis equipment all is for the analysis in laboratory and differentiates particulate or cell etc.; it is processed flow and rests on all the time so far on microliters per second or the milliliter per second, and there is very large difference in this and market for the requirement for the treatment of capacity (greater than rising per second).Thus, how the design that the disengagement chamber that designs for the interdigital electrode dielectrophoresis separation system industrialization of realize reclaiming precious metal and interdigital electrode are right must face the problem with whole separating technology system combination.
By retrieval, not yet find relevant publication document.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of disengagement chamber of interdigital electrode dielectrophoresis separation system is provided, with realize to adopt interdigital electrode dielectrophoresis technical point from Industrialization.
The utility model realizes that the technical scheme of purpose is as follows:
A kind of disengagement chamber of interdigital electrode dielectrophoresis separation system, consist of by separating cavity and interdigital electrode, interdigital electrode is made of many eradications edge electric wire, it is characterized in that: described separation cavity is cylindrical, separating cavity inner edge coaxial space installation interdigital electrode, this interdigital electrode is comprised of anodal insulated electric conductor group and negative pole insulated electric conductor group, and anodal insulated electric conductor is different from negative pole insulated electric conductor height, and the interval arranges.
And the cavity upper and lower end is coaxial to be fixedly mounted with or directly to be shaped with flange separating.
Advantage of the present utility model and good effect are:
The cylindrical disengagement chamber design that the utility model adopts can effectively be saved material and be reduced interior the pressure, and the shape of cylindrical disengagement chamber makes Electric Field Distribution even, reduces and separates the dead angle to reach best result from efficient; Simultaneously, the shape of cylindrical disengagement chamber has been protected electrical breakdown and the short circuit that electrode and power supply do not cause because of local too high voltages and electric current; Flange connection can be connected with the deferent segment parts with the input section of precious metal dielectrophoresis system easily; Avoided to the full extent being connected with power supply near and short circuit phenomenon that may cause, avoided precious metal to be deposited in the bottom and easily collecting not.

Fig. 2 is the cross-sectional view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to the cross section cutaway view Amplified image.
The specific embodiment
The utility model is described in further detail to specific embodiment below by accompanying drawing, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of disengagement chamber of interdigital electrode dielectrophoresis separation system, as shown in Figure 1, consist of by separating cavity 2 and interdigital electrode, it is cylindrical to press and to save material in effective reduction separating cavity, separating the coaxial flange that is fixedly mounted with or directly makes 1 of cavity upper and lower end, can be connected with output block with the input block of precious metal dielectrophoresis system easily; Separating cavity inner edge coaxial space installation interdigital electrode, this interdigital electrode is comprised of anodal insulated electric conductor group 5 and negative pole insulated electric conductor group 4, and anodal insulated electric conductor is different from negative pole insulated electric conductor height, and the interval arranges; Because it is different that anodal insulated electric conductor and negative pole insulated electric conductor have designed in the length of separating the cavity two ends, therefore can have spacing ground below flange the boring of separation cavity and pass and separate cavity and be connected with power supply 3.
The benefit of above-mentioned design is to have avoided to the full extent to be connected near and short circuit phenomenon that may cause with power supply, especially when the bottom of the disengagement chamber that is used for the collection precious metal, owing to the noble metal particles insulated electric conductor of will postponing moves, the electric-field intensity that this design can make the lower end insulated electric conductor reduced before collecting precious metal gradually, avoided precious metal to be deposited in the bottom and the purpose of easily collecting not thereby reach.
