[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7 This utility model provides a technical solution:
[0029] A paint filling device for easy measurement in paint production includes a paint tank 1 and a discharge pipe 2 located at the bottom of the paint tank 1. An installation ring 3 is fixedly connected to the discharge port at the bottom of the paint tank 1. The discharge pipe 2 is fixedly connected to the installation ring 3. A switch valve 4 is installed at the top of the discharge pipe 2. A flow meter 5 is installed below the switch valve 4 on the discharge pipe 2. The installation ring 3 is hollow, and evenly distributed spray holes 6 are opened on its bottom edge. The spray holes 6 are located inside the discharge pipe 2. A blower 7 is installed on the side of the discharge pipe 2. The blower 7 is fixedly connected to the installation ring 3 via a pipe. A pressure pump 8 is fixedly installed on the side of the discharge pipe 2. A conveying pipe 9 is fixedly connected to the outlet of the pressure pump 8. A spray plate 10 is fixedly installed on the side of the flow meter 5. The end of the conveying pipe 9 is fixedly connected to the spray plate 10. Evenly distributed through holes 11 are opened on one side of the spray plate 10 on the flow meter 5.
[0030] In use, the paint tank 1 is used to store the paint to be filled. When the switch valve 4 on the discharge pipe 2 is opened, the paint can be discharged from the discharge pipe 2 for filling. During the filling process, the flow meter 5 detects the paint filling flow rate.
[0031] When it is necessary to clean the inner wall and blades of the flow meter 5, connect the booster pump 8 to the water supply pipeline and start the booster pump 8 and the blower 7 at the same time.
[0032] Blower 7 blows air into mounting ring 3 through pipe. The nozzles 6 evenly distributed on the bottom edge of mounting ring 3 blow the airflow into discharge pipe 2 and flow meter 5. The airflow drives the blades inside flow meter 5 to rotate.
[0033] After pressurizing the water, the pressurizing pump 8 delivers it through the delivery pipe 9 to the spray plate 10 on the side of the flow meter 5. Then, the water is sprayed into the flow meter 5 through the evenly distributed through holes 11 on the flow meter 5 to rinse the inner wall and blades of the flow meter 5.
[0034] The rotating blades enhance the cleaning effect during the rinsing process.
[0035] This paint production equipment features a convenient paint filling device that can automatically clean the paint adhering to the flow meter 5, effectively ensuring the stability of paint filling and metering, and is highly practical.
[0036] A heating section 12 is provided on the conveying pipe 9, and a heating pipe is provided inside the heating section 12;
[0037] A heating section 12 is provided on the delivery pipe 9, and a heating pipe is provided inside the heating section 12. The heating pipe heats the water flowing through the heating section 12, so that the water temperature rises and is sprayed into the flow meter 5. The high temperature water flow can accelerate the dissolution of the coating adhering to the inner wall of the flow meter 5, especially the softening effect on solidified residues. Combined with the flushing action of the spray plate 10, the cleaning efficiency is further improved, ensuring the cleanliness of the inside of the flow meter 5 and guaranteeing the metering accuracy.
[0038] A connecting pipe 13 is fixedly connected to the conveying pipe 9. The top end of the connecting pipe 13 is fixedly connected to the mounting ring 3. Switch valve 2 14 and switch valve 3 15 are respectively provided on the conveying pipe 9 and the connecting pipe 13.
[0039] When it is necessary to clean the inner wall of the discharge pipe 2, close the switch valve 14 on the conveying pipe 9 and open the switch valve 15 on the connecting pipe 13. After the pressurizing pump 8 starts, the water flows through the conveying pipe 9 and the connecting pipe 13 into the mounting ring 3, and then sprays downward from the spray hole 6 at the bottom edge of the mounting ring 3 to flush the inner wall of the discharge pipe 2, effectively removing the paint adhering to the inner wall of the discharge pipe 2 and avoiding residues from affecting the subsequent filling quality.
[0040] Switch valve 1 (4), switch valve 2 (14), and switch valve 3 (15) are all electrically operated.
[0041] Switch valve 1 (4), switch valve 2 (14), and switch valve 3 (15) are all electrically operated and require manual operation.
[0042] Both the nozzle 6 and the through hole 11 are provided with valves 16, and a one-way valve is provided at the connection between the blower 7 and the mounting ring 3.
[0043] The valves 16 inside the nozzle 6 and through-hole 11 are closed during paint filling, preventing paint from entering the nozzle 6 and through-hole 11 and avoiding paint residue that could cause blockage. When cleaning is performed, the blower 7 delivers air to the mounting ring 3 through the pipeline or the pressure pump 8 delivers water to the spray plate 10. The pressure of the airflow or water flow will push open the valves 16, allowing the air or water to spray out smoothly. At the same time, the one-way valve at the connection between the blower 7 and the mounting ring 3 only allows air to flow from the blower 7 to the mounting ring 3, preventing water from flowing back into the blower 7 during cleaning and protecting the blower 7 for normal operation.
[0044] A filter screen 17 is installed at the air inlet of the blower 7;
[0045] A filter screen 17 is installed at the air inlet of the blower 7 to filter the air entering the blower 7.
[0046] Working principle:
[0047] In use, the paint tank 1 is used to store the paint to be filled. When the switch valve 4 on the discharge pipe 2 is opened, the paint can be discharged from the discharge pipe 2 for filling. During the filling process, the flow meter 5 detects the paint filling flow rate.
[0048] When it is necessary to clean the inner wall and blades of the flow meter 5, connect the booster pump 8 to the water supply pipeline and start the booster pump 8 and the blower 7 at the same time.
[0049] Blower 7 blows air into mounting ring 3 through pipe. The nozzles 6 evenly distributed on the bottom edge of mounting ring 3 blow the airflow into discharge pipe 2 and flow meter 5. The airflow drives the blades inside flow meter 5 to rotate.
[0050] After pressurizing the water, the pressurizing pump 8 delivers it through the delivery pipe 9 to the spray plate 10 on the side of the flow meter 5. Then, the water is sprayed into the flow meter 5 through the evenly distributed through holes 11 on the flow meter 5 to rinse the inner wall and blades of the flow meter 5.
[0051] The rotating blades enhance the cleaning effect during the rinsing process.
[0052] This paint production equipment is easy to measure and fill. It can automatically clean the paint adhering to the flow meter 5, effectively ensuring the stability of paint filling and metering, and is highly practical.
[0053] in,
[0054] A heating section 12 is provided on the conveying pipe 9, and a heating pipe is provided inside the heating section 12. The heating pipe heats the water flowing through the heating section 12, so that the water temperature rises and is sprayed into the flow meter 5. The high temperature water flow can accelerate the dissolution of the coating adhering to the inner wall of the flow meter 5, especially the softening effect on solidified residues. Combined with the flushing action of the spray plate 10, the cleaning efficiency is further improved, ensuring the cleanliness of the inside of the flow meter 5 and guaranteeing the metering accuracy.
[0055] When it is necessary to clean the inner wall of the discharge pipe 2, close the switch valve 14 on the conveying pipe 9 and open the switch valve 15 on the connecting pipe 13. After the pressurizing pump 8 starts, the water flows through the conveying pipe 9 and the connecting pipe 13 into the mounting ring 3, and then sprays downward from the spray hole 6 at the bottom of the mounting ring 3 to flush the inner wall of the discharge pipe 2, effectively removing the paint adhering to the inner wall of the discharge pipe 2 and avoiding residues from affecting the subsequent filling quality.
[0056] Switch valve 1 (4), switch valve 2 (14), and switch valve 3 (15) are all electrically operated and require manual operation.
[0057] The valves 16 inside the nozzle 6 and through hole 11 are closed during paint filling, preventing paint from entering the nozzle 6 and through hole 11 and avoiding paint residue that could cause blockage. When cleaning is performed, the blower 7 delivers air to the mounting ring 3 through the pipeline or the pressure pump 8 delivers water to the spray plate 10. The pressure of the airflow or water flow will push open the valves 16, allowing the air or water to be sprayed out smoothly. At the same time, the one-way valve at the connection between the blower 7 and the mounting ring 3 only allows air to flow from the blower 7 to the mounting ring 3, preventing water from flowing back into the blower 7 during cleaning and protecting the blower 7 for normal operation.
[0058] A filter screen 17 is installed at the air inlet of the blower 7 to filter the air entering the blower 7.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
