Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
As shown in fig. 1 and 2, the high-efficiency calcium formate separation device includes a primary settling tank 1 and a secondary settling tank 2, wherein a feed inlet of the primary settling tank 1 is communicated with a calcium formate concentrate outlet through a first pipeline 3, an overflow port is arranged at the top of the primary settling tank 1, the overflow port is communicated with a feed inlet of the secondary settling tank 2 through a second pipeline 4, a first outlet 5 and a second outlet 6 are respectively arranged at the bottoms of the primary settling tank 1 and the secondary settling tank 2, a head tank 7 is communicated below the bottoms of the first outlet 5 and the second outlet 6, a centrifuge 8 is communicated with the head tank 7, generally, the height difference between the head tank 7 and the centrifuge 8 should be at least 2m, a calcium formate outlet 9 and a third pipeline 10 are communicated below the bottom of the centrifuge 8 (specifically, an inner cylinder of the centrifuge 8 should be communicated with the calcium formate outlet 9, the outer cylinder of the centrifuge 8 is communicated with a third pipeline 10), and the third pipeline is communicated with a mother liquid tank 11.
When the calcium formate recovery device is used, calcium formate crystals firstly enter a primary sedimentation tank 1 through a first pipeline 3 to form calcium formate concentrated solution after evaporation and concentration, calcium formate is separated out from the solution under the stirring action, unsaturated solution overflows from the upper part of the primary sedimentation tank 1 to a secondary sedimentation tank 2 and continues to be separated out from the solution under the stirring action, in the process, impurities contained in the calcium formate mother solution after primary sedimentation in the primary sedimentation tank 1 can enter the secondary sedimentation tank 2 along with an overflow port of the primary sedimentation tank 1 and a second pipeline 4, meanwhile, part of calcium formate possibly carried in the mother solution can be subjected to secondary sedimentation in the secondary sedimentation tank 2, and finally, the calcium formate mother solution enters a centrifugal machine 8 for centrifugal separation, so that the yield of the calcium formate can be greatly improved, and the separation purity of the calcium formate can be improved.
Wherein, the outside of one-level subsider 1 and second grade subsider 2 all wraps the spacer 12, and the intussuseption of spacer 12 is filled with cooling water, and has inserted temperature sensor 13 in the spacer 12. Preferably, the temperature in the secondary settling tank 2 is 8-15 ℃ lower than that in the primary settling tank.
Through setting up the cooling water, reduce the temperature of one-level subsider 1 and second grade subsider 2, can subside fast, improve settling efficiency, simultaneously, the interior temperature of second grade subsider 2 is lower than the interior temperature of one-level subsider 1, can further subside the not complete calcium formate that subsides in one-level subsider 1, prevents its waste, can improve the yield of calcium formate.
In order to accelerate sedimentation and improve the sedimentation effect, stirring shafts 14 are arranged inside the primary sedimentation tank 1 and the secondary sedimentation tank 2, the stirring shafts 14 are driven by a motor 15 to rotate, and stirring blades 16 are fixedly arranged on the stirring shafts 14.
In addition, in order to clean the separated calcium formate and remove internal impurities, in the utility model, a cleaning tank 17 is further communicated and arranged on one side of the centrifuge 8 through a fourth pipeline 23, and a water washing tank 19 is further communicated and arranged below the bottom of the centrifuge 8 through a fifth pipeline 18. Because some impurities may still exist in the calcium formate centrifugally separated by the centrifuge 8 and are adsorbed on the surface of calcium formate crystals, the cleaning tank 17 is arranged, and the cleaning liquid is filled in the cleaning tank 17, so that the cleaning liquid enters the centrifuge 8 through the fourth pipeline 23 to clean the calcium formate in the centrifuge 8, impurities possibly contained in the calcium formate can be removed, the purity of the calcium formate is improved, the calcium formate enters a drying process, and the cleaned liquid enters the washing water tank 19 through the fifth pipeline 18.
In addition, before the calcium formate in the centrifuge 8 is cleaned, the mother liquor separated after centrifugation needs to enter the mother liquor tank 11 through the third pipeline 10, and the mother liquor tank 11 is communicated with the secondary sedimentation tank 2 through the sixth pipeline 20. That is, during the centrifugal separation process of the centrifuge 8, unsaturated solution may still remain in the mother liquor, so that calcium formate is not completely crystallized and separated, and therefore, the mother liquor separated in the mother liquor tank 11 is introduced into the secondary sedimentation tank 2 again, so that secondary sedimentation separation can be performed, and the yield of calcium formate is further improved.
In the present invention, the first line 3, the fourth line 23, and the sixth line 20 are provided with the liquid pump 21.
Furthermore, a filter screen 22 is fixedly installed in the third pipeline 19 and the fifth pipeline 18 to prevent calcium formate crystals from entering the mother liquid tank or the washing water tank. Preferably, the filter screen 22 is 120 mesh.
According to the centrifugal separation device, the mesh number of the filter screen is inspected, so that the influence of the proper mesh number of the filter screen on the centrifugal separation is large. The larger mesh number can ensure the primary yield of calcium formate, but the product has more impurities, the filter screen is easy to block and needs to be frequently replaced, the smaller mesh number has better product quality and higher yield, and the results are shown in the following table 1.
Table 1:
mesh number of filter screen 100 mesh 120 mesh 180 mesh
Centrifugal yield 77% 81% 83%
Quality of the product Superior product Superior product Qualified product
Period of operation 2 months old 1 month 17 days
Therefore, by comprehensively considering the yield, the quality and the cost, the mesh number of the filter screen is determined to be 120 meshes.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
