Description

Technical Field

[0001] This utility model relates to the field of enameled wire varnish filtration and packaging, specifically to an enameled wire varnish filtration and packaging system. Background Technology

[0002] Enamelled wire enamel is a key material coated on the surface of metal conductors to form an insulating layer. Its basic components include three main categories: film-forming resin, solvent, and additives. The coating quality of enamelled wire enamel directly depends on the purity of the enamel solution. As a critical step before coating, the filtration process must meet requirements of high precision, stability, and compatibility to remove impurities and ensure the uniformity and insulation performance of the enamel film.

[0003] Traditional enameled wire coating packaging systems often neglect the importance of filtration precision, failing to perform high-precision filtration of the enameled wire coating before packaging. This results in the enameled wire coating being susceptible to contamination by impurities during the packaging process, affecting product quality. Furthermore, the storage environment of the enameled wire coating in the finished product container before filling is unstable, and the coating liquid is at risk of oxidation and contamination upon contact with air. To address these issues, this utility model proposes an enameled wire coating filtration and packaging system. It aims to improve the purity of the enameled wire coating and reduce the risk of contamination by providing a stable storage environment through high-precision filtration, thereby ensuring the quality stability and coating effect of the enameled wire coating. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a filtration and packaging system for enameled wire varnish, which can solve the problems in the prior art where enameled wire varnish is not filtered with high precision before packaging, resulting in the enameled wire varnish being easily contaminated by impurities during the packaging process, affecting product quality, and the storage environment of the enameled wire varnish in the finished product kettle before filling being unstable, with the risk of oxidation and contamination when the varnish comes into contact with air.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a system for filtering and packaging enameled wire enamel in a finished product reactor, characterized in that it includes a finished product reactor system, a filtration system, and a packaging system; the finished product reactor is used to store the enameled wire enamel to be filtered, the filtration system is responsible for high-precision filtration of the enameled wire enamel to remove impurities and ensure the purity of the enamel, and the packaging system is responsible for semi-automatic packaging of the filtered enameled wire enamel to reduce manual intervention and improve packaging efficiency and accuracy.

[0006] The finished product reactor system includes a finished product reactor, a nitrogen purging pipeline and a return pipeline. The nitrogen purging pipeline is connected to the bottom of the finished product reactor. A first valve is provided on the nitrogen purging pipeline. The nitrogen purging pipeline is connected to a nitrogen inlet pipe and a return pipeline. The return pipeline is connected to one side of the top of the finished product reactor. A gear pump is installed on the return line, a basket filter is installed on the return line between the gear pump and the nitrogen purging line, and a second valve is provided on the inlet side of the basket filter, and a fourth valve is installed on the return line on the outlet side of the gear pump. The filtration system includes a filtration pipeline connected to a return pipeline. The fourth valve is located on the return pipeline between the filtration pipeline and the top of the finished product reactor. The inlet and outlet ends of the filtration pipeline are respectively provided with a fifth valve and a sixth valve. A first precision filter and a second precision filter are installed on the filtration pipeline between the fifth valve and the sixth valve. The first precision filter is located near the fifth valve, and the second precision filter is located near the sixth valve. The packaging system includes a semi-automatic filling machine and a weighing scale. The inlet of the semi-automatic filling machine is connected to the outlet of the filter pipeline.

[0007] Furthermore, a third valve is provided on the nitrogen inlet pipe.

[0008] Furthermore, both the first and second precision filters are equipped with precision filter bags, and pressure gauges are installed on the top of both the first and second precision filters.

[0009] Furthermore, the inlet of the semi-automatic filling machine is connected to the outlet of the filter line via a flexible metal hose, and both ends of the flexible metal hose are tightly fitted to the inlet of the semi-automatic filling machine and the outlet of the filter line, and are sealed by a sealing element.

[0010] Furthermore, a pump outlet pressure gauge is installed at the outlet of the gear pump.

[0011] With the above structure, the advantages of this utility model are: by setting up a nitrogen purging pipeline, the storage environment of the enameled wire paint in the finished product kettle is ensured to be stable, the contact between the paint liquid and air is reduced, thereby reducing the risk of oxidation and pollution. Before entering the filtration pipeline, the enameled wire enamel is first filtered through a basket filter. After the initial filtration, it enters the filtration pipeline and undergoes multi-stage precision filtration through a first precision filter and a second precision filter. The multi-stage filtration effectively removes impurities from the enameled wire enamel, greatly improving the purity of the enamel and ensuring the quality of subsequent coating. By combining a semi-automatic filling machine with a weighing scale, the process of measuring and filling the paint liquid is completed automatically, reducing manual intervention, lowering the risk of contamination by impurities, and improving packaging efficiency and accuracy. The system is tightly connected to its various parts, and the pipeline design is reasonable, ensuring the smoothness and stability of the enameled wire paint during transportation and reducing the possibility of paint loss and deterioration during transportation.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments will enable those skilled in the art to gain a more comprehensive understanding of this utility model, but do not limit the scope of the embodiments.

[0014] like Figure 1 As shown, the specific embodiment adopts the following technical solution: an enameled wire enamel filtration and packaging system, including a finished product tank system 1, a filtration system 2, and a packaging system 3; the finished product tank system 1 is used to store the enameled wire enamel to be filtered, the filtration system 2 is responsible for high-precision filtration of the enameled wire enamel to remove impurities and ensure the purity of the enamel, and the packaging system 3 is responsible for semi-automatic packaging of the filtered enameled wire enamel to reduce manual intervention and improve packaging efficiency and accuracy.

[0015] The finished product reactor system 1 includes a finished product reactor 11, a nitrogen purging line 12, and a return line 13. The nitrogen purging line 12 is connected to the bottom of the finished product reactor 11. A first valve 14 is provided on the nitrogen purging line 12. The nitrogen purging line 12 is connected to a nitrogen inlet pipe 15. A third valve 16 is provided on the nitrogen inlet pipe 15. The nitrogen purging line 15 is connected to the return line 13. The return line 13 is connected to one side of the top of the finished product reactor 11. The bottom and top of the finished product reactor 11 are connected through the nitrogen purging line 12 and the return line 13.

[0016] A gear pump 17 is installed on the return line 13. A pump outlet pressure gauge is installed at the outlet of the gear pump 17. The gear pump 17 is selected to be equipped with a safety valve. A basket filter 18 is installed on the return line between the gear pump 17 and the nitrogen purging line 12. A second valve 19 is provided on the inlet side of the basket filter 18. A fourth valve 110 is installed on the return line 13 on the outlet side of the gear pump 17. When the second valve 19 is closed, the first valve 14, the third valve 16 and the fourth valve 110 are opened. Nitrogen enters the nitrogen purging line 12 through the nitrogen inlet pipe 15 and enters the finished product vessel 11 from the bottom. The air in the finished product vessel 11 is discharged to the outside of the filtration system 2 through the return line 13 connected to the top of the finished product vessel 11. When the first valve 14 and the fourth valve 110 are closed and the second valve 19 is opened, nitrogen enters the lower pipeline of the return line 13 through the nitrogen inlet pipe 15, and the air in the return line 13 is also discharged.

[0017] Before filtration begins, open and inspect the basket filter 18 at the front end of the gear pump 17 to remove mechanical impurities and prevent them from entering the gear pump 17, which could affect the normal operation of the entire filtration and packaging system. During the cleaning process, carefully inspect the filter screen of the basket filter 18 to ensure that it is free from damage or blockage. If any issues are found, replace or clean the filter screen promptly to ensure filtration effectiveness. After cleaning, close the inspection port of the basket filter 18 to ensure a good seal and prevent paint leakage.

[0018] Before formal filtration, open the first valve 14 at the bottom of the finished product reactor 11, open the second valve 19 on the return pipeline 13, and start the gear pump 17. The operator should observe whether the outlet pressure of the gear pump 17 is normal and whether the gear pump 17 is operating normally, ensuring that the delivery pressure is within the normal range. If abnormal pressure fluctuations occur, the pump should be stopped immediately for inspection to troubleshoot the cause of the fault, such as pipeline blockage or gear pump malfunction. The gear pump 17 should be restarted only after the problem is resolved. If the pressure and operation are normal, open the fifth valve 22 and the sixth valve 23 before and after the filtration system 2, allowing the enameled wire enamel to flow from the finished product reactor 11 into the filtration system 2 for precision filtration. (First valve 14, fifth valve 22 and sixth valve 23, gear pump 17) The filtration system 2 includes a filter line 21, which is connected to a return line 13. A fourth valve 110 is located on the return line 13 between the filter line 21 and the top of the finished product container 11.

[0019] The inlet and outlet ends of the filter pipeline 21 are respectively equipped with a fifth valve 22 and a sixth valve 23. A first precision filter 24 and a second precision filter 25 are installed on the filter pipeline 21 between the fifth valve 22 and the sixth valve 23. The first precision filter 24 is located near the fifth valve 22, and the second precision filter 25 is located near the sixth valve 23. Both the first precision filter 24 and the second precision filter 25 are equipped with dedicated precision filter bags, and pressure gauges are installed on the top of the first precision filter 24 and the second precision filter 25. The remote pressure gauges on the top of the filters are equipped with overpressure alarms and are interlocked with the gear pump 17 to stop the pump due to overpressure. When the pressure exceeds the set value, the system will automatically trigger the overpressure alarm and interlock with the gear pump 17 to stop the pump due to overpressure, so as to prevent safety accidents caused by excessive pressure.

[0020] When replacing the filter bags of the first precision filter 24 and the second precision filter 25, first close the fifth valve 22 and the sixth valve 23 before and after the first precision filter 24 and the second precision filter 25 to ensure that the system is in a depressurized state to prevent paint leakage and potential safety hazards. Then, slowly open the top cover of the filter and carefully remove the old filter bag according to the specific design of the filter, taking care to avoid dripping residual paint from the filter bag onto the equipment or the ground. After removing the old filter bag, carefully inspect the inside of the filter to ensure that there are no residual impurities or damaged parts. Next, accurately install the new precision filter bag into the filter, ensuring that the filter bag fits tightly against the inner wall of the filter without gaps or wrinkles to ensure the filtration effect. After installation, replace the filter cover and ensure a good seal to prevent paint leakage during the filtration process. After replacement, open the fifth valve 22 and the sixth valve 23 before and after the filter to carry out subsequent filter packaging operations.

[0021] The first precision filter 24 and the second precision filter 25 are selected as composite filter bags of 5umPooxl + 1umPooxl. This type of filter bag can effectively intercept tiny impurity particles in the enameled wire enamel, ensuring that the purity of the filtered enamel reaches an extremely high level. During the filter bag replacement operation, it is also necessary to record the replacement time, batch and other information of the filter bag for subsequent quality traceability and management.

[0022] The packaging system 3 includes a semi-automatic filling machine 31 and a weighing scale. The weighing scale is used in conjunction with the semi-automatic filling machine 31 to automatically measure the filling process. The inlet of the semi-automatic filling machine 31 is connected to the outlet of the filter line 21 through a metal hose. Both ends of the metal hose are tightly fitted to the inlet of the semi-automatic filling machine 31 and the outlet of the filter line, and are sealed with special seals to prevent paint leakage.

[0023] Before formal filtration and packaging, the operator must reconfirm that the metal hose connection between the semi-automatic filling machine 31 and the filter pipeline 21 is secure and well-sealed. After confirmation, the semi-automatic filling machine 31 is started according to the preset packaging specifications and parameters. The weighing scale begins to accurately measure the weight of the paint liquid. When the set weight is reached, the semi-automatic filling machine 31 automatically stops filling, followed by sealing and other subsequent processes, ultimately completing the filtration and packaging process of the enameled wire paint. Throughout the entire operation, the operator must strictly follow the operating procedures to ensure the safe and stable operation of the system. During the entire packaging process, the operator only needs to perform simple monitoring and auxiliary operations, greatly reducing manual intervention and improving packaging efficiency and accuracy.

[0024] The components mentioned above, such as the first valve 14, the second valve 19, the third valve 16, the fourth valve 110, the fifth valve 22, the sixth valve 23, the basket filter 18, the first precision filter 24 and the second precision filter 25, the gear pump 17, the overpressure alarm and the overpressure interlock with the gear pump 17, the semi-automatic filling machine 31, and the weighing scale, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be elaborated further.

[0025] Working principle: After the finished product in the finished product tank 11 is qualified, the second valve 19 is closed, and the first valve 14, the third valve 16 and the fourth valve 110 are opened. Nitrogen gas enters the nitrogen purging pipeline 12 through the nitrogen gas inlet pipe 15 and enters the finished product tank 11 from the bottom. The air in the finished product tank 11 is discharged to the outside of the filter system 2 through the return pipeline 13 connected to the top of the finished product tank 11. The air in the tank is replaced and the tank is left to be filtered and packaged. Then the first valve 14 and the fourth valve 110 are closed and the second valve 19 is opened. Nitrogen gas enters the lower pipeline of the return pipeline 13 through the nitrogen gas inlet pipe 15. The air in the return pipeline 13 is also discharged. This ensures that the storage environment of the enameled wire paint in the finished product tank is stable, reduces the contact between the paint liquid and the air, and thus reduces the risk of oxidation and contamination. Before entering the filter line 21, the enameled wire enamel undergoes preliminary filtration through a basket filter 18. After preliminary filtration, it enters the filtration system 2 and undergoes multi-stage precision filtration through a first precision filter 24 and a second precision filter 25. This multi-stage filtration effectively removes impurities from the enamel, significantly improving its purity and ensuring the quality of subsequent coating. During filtration, operators must closely monitor the remote pressure gauges at the top of the first and second precision filters 24 and 25 to monitor the pressure within them in real time. After precision filtration, the semi-automatic filling machine 31 and a weighing scale work together to automatically complete the metering and filling processes of the enamel, reducing manual intervention, lowering the risk of impurity contamination, and improving packaging efficiency and accuracy.

[0026] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
