[0002] In the coating process, the accuracy and coating efficiency of the coating die are crucial to product quality and cost control. After the coating die evenly coats the slurry on the substrate, some of the slurry will remain or not be fully utilized. If it is not recovered and processed in time, it will not only cause a waste of resources, but may also cause pollution to the environment. Most existing coating equipment lacks a slurry recovery mechanism, resulting in low slurry utilization and a lack of a temperature circulation system. The slurry is prone to agglomeration, deterioration, and low recovery efficiency, which increases the difficulty and cost of subsequent processing and affects the quality and efficiency of subsequent coating. Therefore, there is a need for a recovery device that can efficiently recover slurry and maintain slurry stability. Utility Model Content

[0021] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.
[0022] Example 1
[0023] refer to Figure 1 The coating die slurry recovery device described in this embodiment includes a material receiving trough 1, which is installed below the coating die 4. It also includes a first-stage recovery device, a second-stage recovery device and a heat circulation system. The material receiving trough 1 is installed on the feed port of the first-stage recovery device, and the discharge port of the first-stage recovery device is connected to the feed port of the second-stage recovery device. The first-stage recovery device and the second-stage recovery device are both connected to the heat circulation system. The heat circulation system includes a heat circulation water tank 5, a heat circulation pipe 6 and a pneumatic diaphragm pump 7. The first-stage recovery device, the second-stage recovery device and the heat circulation water tank 5 form a closed heat circulation loop through the heat circulation pipe 6. The pneumatic diaphragm pump 7 drives hot water to circulate in the heat circulation water tank 5 and the heat circulation pipe 6.
[0024] It is worth noting that multiple stages of recovery devices can be set up according to actual conditions, not limited to the first-stage recovery device and the second-stage recovery device, and adjacent stages of recovery devices are connected through pipelines.
[0025] The receiving trough 1 receives the excess slurry flowing out of the coating die head, and receives the collected excess slurry into the first-stage recovery device through a pipeline. After processing by the first-stage recovery device, the processed slurry is transmitted to the second-stage recovery device through a pipeline for processing. After processing by the second-stage recovery device, it is transported to the coating die head or other equipment that needs slurry, thereby realizing the recycling of the slurry; the circulating water tank 5 provides a stable heat source, and the pneumatic diaphragm pump 7 drives hot water to circulate in the heat circulation pipe 6, so that the slurry in the first-stage recovery device and the second-stage recovery device is within a suitable temperature range, thereby preventing the slurry from deteriorating due to temperature changes.
[0026] The cross section of the receiving trough 1 is funnel-shaped, and the width of the receiving trough 1 is greater than the width of the coating die head 4 .
[0027] The high-slope funnel-shaped design ensures that the slurry can flow quickly and smoothly into the first-stage recovery device. The sufficient holding volume of the funnel-shaped inner cavity ensures that it can accommodate a certain amount of slurry. The width of the receiving trough 1 is greater than the width of the coating die 4 to ensure that the slurry can completely enter the receiving trough 1.
[0028] An inclined plate facing the coating die head 4 is provided at one end of the top of the material receiving trough 1 away from the coating die head 4 .
[0029] The inclined plate is a splash-proof device to ensure that the slurry does not overflow during the receiving process.
[0030] The first-stage recovery device includes a first-stage recovery barrel 2, the discharge end of the receiving trough 1 is installed on the feed end of the first-stage recovery barrel 2, a stirring motor 3 is installed on the first-stage recovery barrel 2, and the stirring rod of the stirring motor 3 extends into the first-stage recovery barrel 2.
[0031] The first-stage recovery barrel 2 is the first-stage recovery equipment for the slurry. The stirring motor 3 is used to stir the preliminarily collected slurry to prevent the slurry from settling and agglomerating. The speed and stirring time of the stirring motor 3 can be adjusted according to the properties of the slurry.
[0032] The second-stage recovery device includes a second-stage recovery barrel 10, the discharge end of the first-stage recovery barrel 2 is connected to the feed end of the second-stage recovery barrel 10 through a pipeline, and a pneumatic diaphragm pump 8 is installed on the pipeline, and a stirring motor 11 is installed on the second-stage recovery barrel 10, and the stirring rod of the stirring motor 11 extends into the second-stage recovery barrel 10, and the discharge port of the second-stage recovery barrel 10 faces the coating die 4 or other equipment requiring slurry.
[0033] The second-stage recycling barrel 10 further receives the slurry from the first-stage recycling barrel 2, and the stirring motor 2 11 continues to grind and stir the slurry to make it finer, and then delivers the processed slurry to the coating die head or other equipment that requires slurry to realize the recycling of the slurry.
[0034] Preferably, a slurry filter element 9 is further installed on the pipeline between the discharge end of the first-stage recovery barrel 2 and the feed end of the second-stage recovery barrel 10.
[0035] The slurry filter element 9 filters the slurry to remove impurities and particulate matter therein, thereby improving the purity of the recovered slurry.
[0036] Preferably, when there are more than two stages of recovery devices, the density of the slurry filter element 9 increases step by step, the discharge port of the previous stage recovery device is connected to the feed port of the next stage recovery device through a pipeline, and a pneumatic diaphragm pump 8 is installed on the pipeline, and the discharge port of the last stage recovery device is directed toward the coating die head or other equipment requiring slurry.
[0037] The multi-stage recovery device can be set according to actual conditions. The slurry filter element 9 filters out finer slurry step by step, making the first-stage recovery device purer.
[0038] Preferably, the heat circulation pipe 6 is embedded in the inner wall of the first-stage recovery barrel 2 and the second-stage recovery barrel 10 .
[0039] The heat circulation pipe 6 is embedded in the inner wall of the first-stage recovery barrel 2 and the second-stage recovery barrel 10 so that the slurry in the barrel maintains a certain temperature, avoids agglomeration, and reduces the workload of the stirring motor.
