Description

Technical Field

[0001] The present disclosure relates to the technical field of slurry sanding, and particularly to a slurry stirring and sanding device and a slurry production device. Background Art

[0002] In the preparation of battery separator slurry, sanding is of great significance for improving separator performance, enhancing battery quality, and meeting the requirements of high-performance batteries. Through reasonable sanding processes and parameter control, excellent separator slurry can be prepared, providing strong support for the development of high-performance batteries. Currently, in the separator slurry preparation production line, the sanding process usually sets a sanding circulation route to transport the slurry at the outlet of the sand mill back to the raw material stirring tank or the inlet of the sand mill to form a circulation route.

[0003] For example, a high-efficiency grinding system disclosed in a Chinese patent with the application number CN201320756238.8 includes a vibration grinding machine, a pneumatic diaphragm pump, a horizontal sand mill, and a stirring tank. The vibration grinding machine is sequentially connected to the horizontal sand mill through a ball valve, a feeding pipe, and a pneumatic diaphragm pump, and then the horizontal sand mill is connected back to the vibration grinding machine through a feeding pipe. The slurry to be ground passes through such a circulation system, and the slurry flow is controlled by adjusting the working air pressure of the pneumatic diaphragm pump for circulating grinding between the vibration grinding machine and the sand mill. The slurry in the above solution is circulated and ground between the vibration grinding machine and the sand mill. However, during the circulation process, over-grinding is likely to occur due to improper control, which affects the product performance. Moreover, multiple cycles of grinding will prolong the production time and reduce the production efficiency.

[0004] Another example is a device for preparing submicron slurry disclosed in a Chinese patent with the application number CN202320714868.2, which includes a stirring tank, a sand mill, and a slurry transfer tank. The sand mill is connected to the stirring tank for sanding the slurry stirred by the stirring tank; a flushing liquid inlet and a waste liquid outlet are provided on the sand mill; the slurry transfer tank is connected to the sand mill, and the slurry sanded by the sand mill is temporarily stored in the slurry transfer tank and then returned to the sand mill for circulating sanding. The above slurry preparation device is provided with a slurry transfer tank. The slurry enters the sand mill after being stirred by the stirring tank, the sanded slurry is cached in the slurry transfer tank, and then the performance of the slurry in the slurry transfer tank is detected. The qualified slurry is discharged, and the unqualified slurry is returned to the sand mill for sanding. Although this avoids the situation of over-grinding, the above device has a single circulation route and still has the problem of low production efficiency.

[0005] Therefore, there is an urgent need for a sanding device with a flexible and variable circulation route and capable of improving production efficiency. Summary of the Utility Model

At this time, the well-dispersed slurry in the second circulation and dispersion tank enters the sand mill for sanding, making full use of the device and improving production efficiency. Moreover, the circulation routes between the first circulation and dispersion tank, the second circulation and dispersion tank, and the sand mill are flexible and variable, meeting various requirements for slurry preparation.

[0030] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0031] As Figure 1As shown, the slurry stirring and sanding device 10 of an embodiment includes a raw material stirring tank 100, a sand mill 200, a first liquid pump 300, a second liquid pump 400, a first circulation dispersion tank 500, a second circulation dispersion tank 600, and a pipeline structure 700. The discharge port of the raw material stirring tank 100 is connected to the first liquid pump 300. The pipeline structure 700 includes a first pipeline 710, a second pipeline 720, a third pipeline 730, and a first discharge pipe 740. One end of the first pipeline 710 is connected to the first liquid pump 300, and the other end of the first pipeline 710 is respectively connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600. One end of the second pipeline 720 is connected to the feed port of the sand mill 200, and the other end of the second pipeline 720 is respectively connected to the discharge ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600. One end of the third pipeline 730 is connected to the discharge port of the sand mill 200, and the other end of the third pipeline 730 is respectively connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600. The first discharge pipe 740 is respectively communicated with the second pipeline 720 and the second liquid pump 400, so that the slurry enters the first discharge pipe 740 through the second pipeline 720.

[0032] In this embodiment, the raw material stirring tank 100 is used to stir and mix the slurry. High-speed dispersion blades are provided in the first circulation dispersion tank 500 and the second circulation dispersion tank 600, so that air bubbles can be effectively eliminated when the slurry is dispersed in the first circulation dispersion tank 500 or the second circulation dispersion tank 600, thereby improving the quality of the slurry. The sand mill 200 is used to sand the dispersed slurry, so that the solid particles in the slurry are further refined and evenly dispersed in the solvent. Further, the first pipeline 710 is used to transport the slurry in the raw material stirring tank 100 to the first circulation dispersion tank 500 or the second circulation dispersion tank 600. The second pipeline 720 is used to transport the slurry in the first circulation dispersion tank 500 or the second circulation dispersion tank 600 to the sand mill 200. The third pipeline 730 is used to transport the slurry in the sand mill 200 back to the first circulation dispersion tank 500 or the second circulation dispersion pipe. The discharge pipe discharges the slurry in the second pipeline 720 through the second liquid pump 400 to enter the next process.

[0033] Further, the circulation route of this device is flexible and changeable, and there are at least the following four circulation modes:

[0034] 1. Raw material mixing tank → First circulation dispersion tank → Sand mill → Second circulation dispersion tank. That is, the slurry enters the first circulation dispersion tank from the raw material mixing tank for dispersion. After dispersion, it enters the sand mill from the first circulation dispersion tank. After sand grinding, it enters the second circulation dispersion tank for further dispersion. At this time, the slurry in the second circulation dispersion tank is detected. If the slurry is qualified, the slurry in the second circulation dispersion tank enters the first discharge pipeline through the second pipeline for discharging. If the slurry is unqualified, the slurry in the second circulation dispersion tank is repeated once the circulation step, that is, the second circulation dispersion tank → Sand mill → First circulation dispersion tank. At this time, the slurry in the first circulation dispersion tank is detected again. If the slurry is qualified, it enters the discharge pipe through the second pipeline for discharging.

[0035] 2. Raw material mixing tank → Second circulation dispersion tank → Sand mill → First circulation dispersion tank. That is, the slurry is first stirred in the raw material mixing tank and then enters the second circulation dispersion tank for dispersion, and then sequentially passes through the sand mill and the first circulation dispersion tank. Its process principle is the same as that of the first circulation route.

[0036] 3. Raw material mixing tank → First circulation dispersion tank → Sand mill → First circulation dispersion tank. The slurry is stirred in the raw material mixing tank and then enters the first circulation dispersion tank for dispersion, then enters the sand mill for sand grinding and then returns to the first circulation dispersion tank for further dispersion. If the slurry in the first circulation dispersion tank is qualified, it enters the discharge pipe through the second pipeline for discharging. That is, this circulation mode is a single-line circulation and does not pass through the second circulation dispersion tank.

[0037] 4. Raw material mixing tank → Second circulation dispersion tank → Sand mill → Second circulation dispersion tank. This circulation mode has the same process principle as the third one.

[0038] It can be understood that the first circulation dispersion tank 500 and the second circulation dispersion tank 600 can be operated in parallel to achieve continuous production, thereby improving efficiency. Moreover, the slurry in the tanks can be produced and quality-controlled as an independent batch, which is convenient for traceability and management. At the same time, the parameters such as the rotation speed, sand grinding time, and grinding medium of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 can be set to different values to target the slurry characteristics of different batches. In this way, through the circulation of the first circulation dispersion tank 500 and the second circulation dispersion tank 600, the slurry sand grinding is more uniform and the sand grinding effect is better. Further, through the circulation of the first circulation dispersion tank 500 and the second circulation dispersion tank 600, the continuous operation time of the sand mill 200 can be reduced, thereby reducing equipment wear and failure rate.

[0039] The above-mentioned slurry stirring and sanding device 10 has the discharge port of the raw material stirring tank 100 connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 respectively through the first pipeline 710. The feed port of the sand mill 200 is connected to the discharge ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 respectively through the second pipeline 720. The discharge port of the sand mill 200 is connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 through the third pipeline 730, and the second pipeline 720 is connected to the first discharge pipe 740. Specifically, the first circulation dispersion tank 500 and the second circulation dispersion tank 600 can operate in parallel. The slurry in the first circulation dispersion tank 500 enters the sand mill 200 for sanding and then enters the next process. At this time, the well-dispersed slurry in the second circulation dispersion tank 600 enters the sand mill 200 for sanding, making full use of the device and improving production efficiency. Moreover, the circulation routes between the first circulation dispersion tank 500, the second circulation dispersion tank 600 and the sand mill 200 are flexible and variable, meeting various requirements for slurry preparation.

[0040] As Figure 1 shown, in one of the embodiments, the pipeline structure 700 further includes a first control valve 711 and a second control valve 712. The first control valve 711 is installed at the first pipeline 710 adjacent to the first circulation dispersion tank 500, and the first control valve 711 is used to control the slurry in the first pipeline 710 to enter the first circulation dispersion tank 500. The second control valve 712 is installed at the first pipeline 710 adjacent to the second circulation dispersion tank 600, and the second control valve 712 is used to control the slurry in the first pipeline 710 to enter the second circulation dispersion tank 600. In this embodiment, both the first control valve 711 and the second control valve 712 are electrically connected to the control system so that the corresponding slurry in the first pipeline 710 enters the first circulation dispersion tank 500 or the second circulation dispersion tank 600. Specifically, if it is necessary to press the slurry into the first circulation dispersion tank 500, at this time the control system controls the first control valve 711 to open and the second control valve 712 to close, and the first liquid pump 300 presses the slurry in the first pipeline 710 into the first circulation dispersion tank 500 for high-speed dispersion.

[0041] As Figure 1As shown, in one embodiment, the pipeline structure 700 further includes a third control valve 713, a fourth control valve 714, and a fifth control valve 715. The third control valve 713 is installed at the second pipeline 720 adjacent to the first circulation dispersion tank 500. The fourth control valve 714 is installed at the second pipeline 720 adjacent to the sand mill 200. The fifth control valve 715 is installed at the second pipeline 720 adjacent to the second circulation dispersion tank 600. The third control valve 713 and the fourth control valve 714 are used to jointly control the slurry in the first circulation dispersion tank 500 to enter the sand mill 200. The fourth control valve 714 and the fifth control valve 715 are used to jointly control the slurry in the second circulation dispersion tank 600 to enter the sand mill 200. In this embodiment, the third control valve 713, the fourth control valve 714, and the fifth control valve 715 are all electrically connected to the control system. When the third control valve 713 and the fourth control valve 714 are opened and the fifth control valve 715 is closed, the slurry in the first circulation dispersion tank 500 enters the sand mill 200 through the second pipeline 720. When the fourth control valve 714 and the fifth control valve 715 are opened and the third control valve 713 is closed, the slurry in the second circulation dispersion tank 600 enters the sand mill 200 through the second pipeline 720.

[0042] As Figure 1 shown, in one embodiment, the pipeline structure 700 further includes a sixth control valve 716 and a seventh control valve 717. The sixth control valve 716 is installed at the third pipeline 730 adjacent to the first circulation dispersion tank 500. The sixth control valve 716 is used to control the slurry in the sand mill 200 to enter the first circulation dispersion tank 500. The seventh control valve 717 is installed at the third pipeline 730 adjacent to the second circulation dispersion tank 600. The seventh control valve 717 is used to control the slurry in the sand mill 200 to enter the second circulation dispersion tank 600. In this embodiment, the sixth control valve 716 and the seventh control valve 717 are both electrically connected to the control system to enable the slurry in the sand mill 200 to enter the first circulation dispersion tank 500 or the second circulation dispersion tank 600. Specifically, when the sixth control valve 716 is opened and the seventh control valve 717 is closed, the slurry in the sand mill 200 enters the first circulation dispersion tank 500 through the third pipeline 730. When the sixth control valve 716 is closed and the seventh control valve 717 is opened, the slurry in the sand mill 200 enters the second circulation dispersion tank 600 through the third pipeline 730.

[0043] As Figure 1As shown, in one embodiment, the pipeline structure 700 further includes a reflux pipeline 750, an eighth control valve 718, and a ninth control valve 719. Both ends of the reflux pipeline 750 are respectively connected to the first discharge pipe 740 and the feed inlet of the raw material mixing tank 100. The eighth control valve 718 is installed on the reflux pipeline 750, and the ninth control valve 719 is installed on the first discharge pipe 740. The eighth control valve 718 and the ninth control valve 719 are used to jointly control the return of the slurry in the first discharge pipe 740 to the raw material mixing tank 100. It can be understood that if the slurry remains unqualified after cyclic dispersion and sanding, it is necessary to transport the slurry back to the raw material mixing tank 100 for re-dispersion and mixing. Both the eighth control valve 718 and the ninth control valve 719 are electrically connected to the control system. When the eighth control valve 718 is opened and the ninth control valve 719 is closed, the slurry in the first discharge pipe 740 enters the reflux pipeline 750 and then enters the raw material mixing tank 100. When the eighth control valve 718 is closed and the ninth control valve 719 is opened, the slurry in the first discharge pipe 740 is normally discharged to enter the next process.

[0044] As Figure 1 shown, in one embodiment, the pipeline structure 700 further includes a second discharge pipe 721, a tenth control valve 722, and an eleventh control valve 723. The second discharge pipe 721 is connected to the first pipeline 710. The tenth control valve 722 is installed on the first pipeline 710, and the eleventh control valve 723 is installed on the second discharge pipe 721. It can be understood that for the slurry of specific raw materials or processes, after being mixed in the raw material mixing tank 100, cyclic dispersion and sanding are not required. At this time, the control system controls the tenth control valve 722 to close and the eleventh control valve 723 to open, so as to transport the slurry in the first pipeline 710 to the second discharge pipe 721 and then enter the next process. Further, when the control system controls the tenth control valve 722 to open and the eleventh control valve 723 to close, the slurry in the first pipeline 710 is transported to the first cyclic dispersion tank 500 or the second cyclic dispersion tank 600.

[0045] As Figure 1 shown, in one embodiment, the connection junction of the first pipeline 710 and the second discharge pipe 721 is located between the tenth control valve 722 and the eleventh control valve 723, so that the slurry can enter the second discharge pipe 721 more accurately.

[0046] As Figure 1As shown, in one embodiment, the first circulation dispersion tank 500 is provided with a first sampling member 510, and the first sampling member 510 is used to sample the slurry in the first circulation dispersion tank 500. In this embodiment, the first sampling member 510 includes a control valve and a pipeline. When the control valve is opened, the slurry in the first circulation dispersion tank 500 flows out through the pipeline, and the staff detects the slurry to determine whether the slurry in the first circulation dispersion tank 500 is qualified.

[0047] As Figure 1 shown, in one embodiment, the second circulation dispersion tank 600 is provided with a second sampling member 610, and the second sampling member 610 is used to sample the slurry in the second circulation dispersion tank 600. In this embodiment, the second sampling member 610 includes a control valve and a pipeline. When the control valve is opened, the slurry in the second circulation dispersion tank 600 flows out through the pipeline, and the staff detects the slurry to determine whether the slurry in the second circulation dispersion tank 600 is qualified.

[0048] As Figure 1 shown, in one embodiment, the second pipeline 720 is provided with a third sampling member 724, and the third sampling member 724 is used to sample the slurry before entering the sand mill 200. The third pipeline 730 is provided with a fourth sampling member 731, and the fourth sampling member 731 is used to sample the slurry after sanding. In this embodiment, both the third sampling member 724 and the fourth sampling member 731 include a control valve and a pipeline. When the control valve of the third sampling member 724 is opened, the slurry in the second pipeline 720 flows out through the pipeline to sample and detect the slurry before entering the sand mill 200. When the control valve of the fourth sampling member 731 is opened, the slurry in the third pipeline 730 flows out through the pipeline to sample and detect the slurry after sanding. In this way, by detecting the quality of the slurry before and after sanding, the process parameters can be adjusted in time or reworked to further improve the sanding quality.

[0049] This application also provides a slurry production device, including the slurry stirring and sanding device 10 described in any of the above embodiments.

[0050] Compared with the prior art, the present disclosure has at least the following advantages:

[0051] The above-mentioned slurry stirring and sanding device 10 has the discharge port of the raw material stirring tank 100 connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 respectively through the first pipeline 710. The feed port of the sand mill 200 is connected to the discharge ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 respectively through the second pipeline 720. The discharge port of the sand mill 200 is connected to the feed ports of the first circulation dispersion tank 500 and the second circulation dispersion tank 600 through the third pipeline 730, and the second pipeline 720 is connected to the first discharge pipe 740. Specifically, the first circulation dispersion tank 500 and the second circulation dispersion tank 600 can operate in parallel. The slurry in the first circulation dispersion tank 500 enters the sand mill 200 for sanding and then enters the next process. At this time, the well-dispersed slurry in the second circulation dispersion tank 600 enters the sand mill 200 for sanding, making full use of the device and improving production efficiency. Moreover, the circulation routes between the first circulation dispersion tank 500, the second circulation dispersion tank 600 and the sand mill 200 are flexible and variable, meeting various requirements for slurry preparation.

[0052] The above embodiments only represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
