However, in the extraction process, the raffinate and back extraction liquid often contain oil phase components due to the presence of hydrophilic groups in the organic phase, so that the cobalt sulfate solution inevitably contains oil phase components, which affects the product quality of the cobalt sulfate solution. These oil phases are mainly dispersed oil, dissolved oil and emulsified oil. At present, the main way to remove the above-mentioned oil phase is adsorption treatment, and a porous adsorption resin with water oil removal capacity is used as an adsorption column to slowly pass the cobalt sulfate solution containing oil phase through the adsorption column to remove the oil phase. However, the traditional adsorption column oil removal device is mainly a single column structure.

DETAILED DESCRIPTION

[0023] The utility model will be further explained in detail below in combination with the drawings and specific embodiments.

[0024] Example one

[0025] The embodiment discloses a kind of cobalt sulfate solution oil removal devices, structural settings as Figure 1 Shown, mainly including filter main body 1, two major structural parts of multi-station connector 2;

[0026] Wherein, filter main body 11 is formed by multiple adsorption column units 3, and adsorption column unit 3 is the adsorption column structure of traditional form, and adsorption resin is filled in each adsorption column unit 2, and the top of each adsorption column unit 3 is provided with sample inlet 4, and the bottom is provided with sample outlet 5;

[0027] Utilize multi-station connector 2, integrate multiple adsorption column units 3 into one, to form Figure 1 Shown oil removal device core part.

[0028] As Figure 2 Shown, multi-station connector 2 is petal-shaped, and mounting groove 21 is formed along the circumferential direction in multi-station connector 2, and the number of mounting groove 21 is consistent with the number of adsorption column unit 3, so that one mounting groove 21 matches one adsorption column unit 3, and after the end of adsorption column unit 3 is clamped into corresponding mounting groove 21, the end connector structure of adsorption column unit 3 is fixedly connected with multi-station connector 2. According to the structure and material of multi-station connector, adsorption column unit connector, etc. Selection fixed mode, for example, adhesive connection, welding connection, etc.

[0029] Multiple adsorption column units are fixedly assembled with multi-station connector 2 at top end, and also fixedly assembled with multi-station connector 2 at bottom end. Thus, one multi-station connector 2 is fixedly connected at the top end and the bottom end of filter main body 1, to assemble multiple adsorption column units 3 into one by using the multi-station connector 2 at top end and bottom end.

[0030] It can be seen from this that for the cobalt sulfate solution deoiling device disclosed in this embodiment, a multi-station connector with specific shape characteristics is designed. The multi-station connector can be used to integrate multiple adsorption column units into one, so as to be used for deoiling the cobalt sulfate solution. The petal-shaped integrated distribution of the filter main body has a compact structure and occupies a small space. It can be used together for deoiling the cobalt sulfate solution and has the advantage of high treatment efficiency.

[0031] Example 2

[0032] This embodiment discloses a cobalt sulfate solution deoiling device, the structure of which is as follows: Figure 3 As shown, based on the structure disclosed in Example 1, in order to further improve the controllability of multiple adsorption column units and the convenience of oil removal treatment, a master sample tray 7 is added. The master sample tray 7 is connected to each adsorption column unit 3, so that the master sample tray 7 can be used for one-time sample addition.

[0033] First, vertical poles 6 are fixedly provided on the multi-station connector 2 located at the top of the filter body 1. There can be multiple poles 6, and the main sample tray 7 is supported and connected by the poles 6.

[0034] Secondly, the total sample feed tray 7 is a thin disc with a hollow interior, and a total sample addition port 8 is provided at the top of the total sample feed tray 7 , and a plurality of branch interfaces 10 are provided at the bottom of the total sample feed tray 7 .

[0035] Generally speaking, the number of branch interfaces 10 provided is consistent with the number of adsorption column units provided, with one branch interface 10 connected to the sample inlet 4 of one adsorption column unit 3 via a hose 9. Furthermore, to ensure that the cobalt sulfate solution added to the master sample tray 7 enters each adsorption column unit, an infusion flow regulator 11 is provided on each hose 9. The infusion flow regulator 11 is located on the hose 9 near one end of the branch interface 10.

[0036] The infusion flow regulator 11 is a finished product, such as Figure 4 As shown, with a scroll wheel, the hose 9 passes through the cavity of the infusion flow regulator. Since the cavity space is characterized by gradually shrinking from the bottom to the top, the liquid flow through the hose can be adjusted by rolling the scroll wheel. Moreover, when the scroll wheel rolls to the narrowest position of the cavity, the infusion flow regulator 11 is in a closed state. Therefore, the hose currently in the state can be controlled to be unable to deliver the cobalt sulfate solution from the main sample tray 7 to the corresponding adsorption column unit, so that the operator can select the number of adsorption column units to be used according to the overall situation of the cobalt sulfate solution to be deoiled.

[0037] Therefore, for the disclosed cobalt sulfate solution oil removal device, the plurality of adsorption column units are integrated and can be used together for oil removal treatment of the cobalt sulfate solution, having the advantage of high treatment efficiency. Moreover, the petal-shaped integrated distribution of the filter main body also has the advantages of compact structure and small space occupation.

[0038] Further, the total sample inlet structure is added, the cobalt sulfate solution to be treated is added at the total sample inlet, and the solution is sent into each adsorption column unit through the hose through each branch interface, so as to remove the oil phase component in the cobalt sulfate solution by the high molecular porous adsorption resin. The whole treatment process only needs to add sample at the total sample inlet, without adding sample to each adsorption column unit respectively, thus having the advantage of convenient operation. Moreover, the infusion flow regulator is arranged on the hose, which is often used in the infusion field, has low use cost and good control effect, thus the sample adding speed of the adsorption column unit of the cobalt sulfate solution oil removal device of the embodiment can be adjusted, and the number of the adsorption column unit selected for use can also be controlled, greatly increasing the use flexibility of the oil removal device.

[0039] Embodiment three

[0040] Further considering the actual use of the cobalt sulfate solution oil removal device, i.e. the need for cobalt sulfate sample adding operation, a workbench is arranged. The structure disclosed in embodiment one or embodiment two is installed on the workbench, specifically the filter main body 1 or the filter main body 1 and the total sample inlet 7 are installed on the workbench through the multi-station connector 2.

[0041] As shown in Figure 5 The workbench includes a bottom plate 15, a vertical plate 14 vertically fixed at one end of the bottom plate 15, a connecting plate 13 fixed on one side of the vertical plate 14, and a connecting lug 12 fixed on one side of the multi-station connector 2 at the top and bottom, respectively, and adapted to the connecting plate 13. The connecting lug 12 and the connecting plate 13 are locked and connected through a screw and a nut structure. Thus, by using the thread locking feature of the nut and the adaptive connection of the connecting lug and the connecting plate, the filter main body 1 or the filter main body 1 and the total sample inlet 7 are installed on the workbench through the multi-station connector 2.

[0042] The whole device is supported and arranged through the workbench, which is more conducive to the sample adding operation of the cobalt sulfate solution, thus better completing the oil removal treatment.

[0043] As can be known from the above, the cobalt sulfate solution oil removal device has the advantages of high use efficiency, large solution treatment capacity, simple operation and strong controllability.

[0044] In addition, if a plurality of single adsorption columns are used for oil removal treatment, although the working efficiency can be improved, compared with the cobalt sulfate solution oil removal device, the integration degree of the plurality of adsorption columns is not high, the space occupation is large, the sample cannot be added at one time, and the operation is time-consuming and laborious.

[0045] The above embodiment is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the technical solution range of the present application also belong to the protection scope of the present application.
