DETAILED DESCRIPTION

[0020] The technical scheme of the present application will be further described below in combination with examples and drawings.

[0021] As Figure 1 and Figure 2 shown, the present coolant recycling evaluation device comprises:

[0022] An operation table is provided with a magnetic stirrer 10, a plurality of sample cells 11 are uniformly distributed on the magnetic stirrer 10, and a mixed liquid containing cooling liquid and silicon powder particles is added in the sample cells 11, and the magnetic stirrer 10 drives the mixed liquid in each sample cell 11 to stir through a magnetic sub (not shown in the figure);

[0023] A suction filtration device 20 is arranged on one side of the operation table, and the suction filtration device 20 is used for suction filtration of the stirred mixed liquid, and part of the suction-filtered mixed liquid reenters the sample cell 11.

[0024] A detection table 30 is arranged on the other side of the operation table, and a measuring cup 33 for receiving part of the suction-filtered mixed liquid is arranged on the detection table 30, a turbidimeter 31 and a comprehensive detector 32 are arranged around the detection table 30, the turbidimeter 31 is provided with a detection window 311 on the side facing the measuring cup 33, and two detection probes are arranged on the comprehensive detector 32.

[0025] In order to save cost and meet the demand of green development, some slicing companies use a recycling mode for the use of cooling liquid, and the cut mortar reenters the cutting system after pressure filtration, so as to improve the utilization rate of the cooling liquid, reduce the generation of waste water, and achieve the purposes of cost reduction and benefit increase, energy saving and emission reduction. However, there is no reliable evaluation of large circulation cutting on the market at present, and the detection demand of customers for the recycling use of cooling liquid cannot be met.

[0026] Therefore, the utility model provides a kind of cooling liquid recycling evaluation device, and the related performance of cooling liquid after filtration is determined by carrying out turbidity, pH, conductivity and COD detection to the mixed liquid containing cooling liquid after suction filtration;Meanwhile, corresponding materials are added to the cooling liquid after suction filtration, and suction filtration detection work is repeated, to obtain the performance results of cooling liquid after recycling, which is convenient for subsequent practical application.

[0027] Specifically, in the embodiment, a constant-temperature magnetic stirrer 10 is preferably used, a certain amount of pure water is first added in the sample cell 11 during detection, silicon powder particles and cooling liquid are added in a certain proportion, and the mixed liquid is stirred at a suitable temperature to facilitate rapid mixing and obtain the required mixed liquid.

[0028] Then, the mixed liquid is suction-filtered to obtain filtered mixed liquid, part of the suction-filtered mixed liquid is poured into the measuring cup 33 of the detection table 30 for related performance detection, and the remaining mixed liquid reenters the sample cell 11. In actual operation, the mixed liquid can also be filtered by pressure filtration.

[0029] The mixed liquid reentering the sample cell 11 is continuously supplemented with a certain proportion of pure water, cooling liquid and silicon powder particles, and continuously stirred to obtain new mixed liquid, and suction filtration and detection work are repeated to obtain corresponding performance data.

[0030] It is worth mentioning that, since the silicon powder particles are filtered out during the filtration process, the proportion of the silicon powder particles added here is the same as the first time, and the cooling liquid and pure water are partially consumed, so appropriate addition is required, and the proportion is different from the first time.

[0031] Preferably, a plurality of magnetic circles 12 are arranged on the panel of the magnetic stirrer 10, and each magnetic circle 12 can place a sample cell 11. In the embodiment, the panel of the magnetic stirrer 10 is preferably provided with the magnetic circle 12, and the magnetic circle 12 generates a magnetic field, which drives the magnetic particles in each sample cell 11 to rotate under the action of the magnetic field (magnetic force), so as to promote the stirring of the mixed liquid in the sample cell 11. The specific number of magnetic circles 12 is not limited here.

[0032] Further, the turbidimeter 31 is also provided with a display window 312.

[0033] In the embodiment, the turbidimeter 31 is preferably provided with a detection window 311 and a display window 312 on the side facing the measuring cup 33. During actual work, the detection window 311 can detect the turbidity of the mixed liquid in the measuring cup 33, and the detection results are displayed in real time on the display window 312, which is convenient to operate.

[0034] Preferably, the comprehensive detector 32 is fixedly provided with a clamping frame 40 on one side, and two detection probes are arranged on the clamping frame 40, and the two detection probes are respectively a pH probe 321 and a conductivity probe 322.

[0035] Here, the comprehensive detector 32 is preferably used to detect the pH value and conductivity of the mixed liquid in the measuring cup 33. The pH probe 321 and the conductivity probe 322 are connected to the comprehensive detector 32, and the clamping frame 40 is arranged to facilitate the arrangement of the two detection probes. When performing detection work, the two detection probes can be inserted into the measuring cup 33, and the corresponding detection data will be displayed in real time on the comprehensive detector 32, which is convenient to operate.

[0036] Further, the operation table is also provided with a COD detector 50, and the COD detector 50 is provided with a measuring tube 51 for receiving part of the mixed liquid after filtration.

[0037] In the embodiment, the operation table is also provided with the COD detector 50. During actual operation, part of the mixed liquid taken out after filtration can be distributed to the measuring tube 51 of the COD detector 50, and the COD of this part of the mixed liquid is determined by the COD detector 50 to obtain the corresponding value, so as to detect the corresponding performance of the mixed liquid after filtration.

[0038] The turbidity, pH value, conductivity and COD value of the cooling liquid are obtained through multiple operations, and the values measured each time are recorded and analyzed. The conductivity and COD value increase rapidly in the first few cycles, while the turbidity and pH value increase slowly.

[0039] When the number of cycles increases, if the values gradually tend to be stable, it indicates that the performance of the cooling liquid is stable when used in cycles, so it can be determined that the recycling of the cooling liquid will not have a great impact on the cutting work, and the cooling liquid can be recycled in actual operation to improve the utilization rate of the cooling liquid.

[0040] It is worth mentioning that during the cycle test, the related parts of the sample pool 11, the measuring cup 33, the measuring tube 51 and the filtration device 20 used each time are preferably new or drained after cleaning to avoid the influence of residual mixed liquid on the test results.

[0041] The evaluation device can detect multiple samples at the same time, detect the related performance of different cooling liquids, and select appropriate cooling liquids.

[0042] The utility model discloses a simulation of the large cycle cutting process through multiple filtrations, converts the large cycle cutting process into a simulation evaluation case, realizes the purposes of online testing the turbidity, pH value, conductivity and COD value of the filtrate, and further judges whether the cycle system is stable by monitoring the COD, which is beneficial to the smooth progress of the simulation evaluation work.

[0043] The cooling liquid recycling evaluation device has a reasonable structure, detects the turbidity, pH, conductivity and COD of the mixed liquid containing the cooling liquid after filtration to determine the related performance of the cooling liquid after filtration, adds the corresponding materials to the cooling liquid after filtration, repeats the filtration detection work, obtains the performance results of the recycled cooling liquid, and is convenient for subsequent actual application.
