Description

Technical Field

[0001] This utility model relates to the field of water-based paint production and formulation technology, and in particular to an anti-curing device for water-based paint formulation. Background Technology

[0002] Water-based paint is a type of coating that uses water as a diluent and does not contain organic solvents. It is commonly used for coating furniture and floors. Once the paint can containing water-based paint is opened, it will gradually solidify, affecting subsequent normal coating use. To prevent the water-based paint from solidifying after opening, an anti-curing device is needed to prevent the unused water-based paint from solidifying.

[0003] As disclosed in Utility Model No. CN214862745U, a device for preventing water-based paint curing by stirring and mixing includes a stirring drum, a feed pipe, an electric telescopic rod, a fixed plate, a first motor, a stirring shaft, a through hole, stirring blades, a bearing seat, a rotating drum connected to the inner wall of the bearing seat and sleeved on the stirring shaft, a scraper for scraping water-based paint adhering to the inner side and bottom walls of the stirring drum, a connecting rod between the upper end of the scraper and the rotating drum, a drive unit for driving the rotating drum to rotate, a discharge pipe at the bottom of the stirring drum, a control valve on the discharge pipe, and a support leg at the bottom of the stirring drum. This device not only thoroughly stirs the water-based paint but also scrapes and cleans the material adhering to the inner side and bottom walls of the stirring drum, thus significantly preventing the water-based paint from curing. However, this technical solution avoids the curing of water-based paint by heating and stirring during application. However, the heating process will cause the water-based paint to lose moisture, which will affect the performance of the water-based paint. There is a technical problem that it is not possible to cool the evaporated water to prevent the water-based paint from losing moisture and to regulate the temperature inside the device at the same time as heating to prevent the water-based paint from curing.

A temperature sensor is provided at the top of the rear end of the inner cylinder. An exhaust fan is provided at the front end of the top of the cover. A cooling box is provided at the rear end of the top of the cover. Heat dissipation fins are provided on both sides of the cooling box. A steam pipe is provided at the output end of the exhaust fan. A condenser pipe is provided inside the cooling box. A water inlet is inserted into the rear end of the bottom of the cooling box. A filling port is provided at the top of the rear end of the cooling box. A drain port is provided at the bottom of the rear end of the cooling box.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By installing a cooling circulation component at the top of the cover, when the water-based paint is heated by an electric heating plate to prevent it from curing, the exhaust fan is activated to draw out the water evaporated during heating and transport it through a steam pipe to the condenser pipe inside the cooling box. The evaporated water is condensed into water through heat exchange with the condensate in the cooling box. Finally, the condensate is reintroduced into the water-based paint inside the device through the water inlet. At the same time, the cooling box is cooled by heat dissipation fins to prevent the condensate from overheating and affecting the heat exchange efficiency. This avoids excessive water loss when heating the water-based paint. Furthermore, the water added after condensation can be used to cool the inside of the device to prevent the water-based paint from overheating. This achieves the effect of preventing the performance of the water-based paint from deteriorating while heating it, and is highly feasible.

[0013] 2. By installing scraping components at both ends of the rotating shaft, the rotating shaft drives the scraper to rotate on the inner side wall of the inner cylinder and the bottom of the outer cylinder through the connecting rod when the rotating shaft rotates. This prevents the water-based paint adhering to the inner wall of the device from curing, and also prevents the water-based paint on the inner wall of the device from being overheated and losing its performance. At the same time, the water-based paint adhering to the inner wall of the device can be scraped off and discharged when the water-based paint is discharged. The protective rubber strip can prevent the scraper from scratching the bottom of the outer cylinder and the inner wall of the inner cylinder, thus affecting the service life of the device.

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides an anti-curing device for water-based paint preparation, including an outer cylinder 1, an inner cylinder 4 passing through the inner cylinder 1, a support plate 2 at the bottom edge of the outer cylinder 1, a touch panel 3 at the bottom of the front end of the outer cylinder 1, a discharge port 12 inserted into the bottom end of the outer cylinder 1, a solenoid valve 13 inside the discharge port 12, a cover 10 at the top of the inner cylinder 4, an inlet 6 inserted into one side of the top of the cover 10, through which water-based paint is fed into the device, a drive motor 5 at the middle position of the top of the cover 10, and electric heating plates 22 at both ends of the outer wall of the inner cylinder 4 inside the outer cylinder 1, which heat the water-based paint to prevent it from curing. The inner cylinder 10 has a rotating shaft 16 inside, and stirring rods 17 are provided at both ends of the outer side of the rotating shaft 16. The stirring rods 17 are arranged at equal intervals at both ends of the outer side of the rotating shaft 16. A sealed bearing 20 is provided at the middle position of the bottom end of the cover 10. The top of the rotating shaft 16 is connected to the output end of the drive motor 5 through the sealed bearing 20. While the water-based paint is heated by the electric heating plate 22, the drive motor 5 is started to drive the rotating shaft 16 to rotate and stir the stirring rods 17 to further prevent the water-based paint from curing. A temperature sensor 25 is provided at the top of the rear end of the inner cylinder 4. The temperature inside the device is monitored by the temperature sensor 25. When the water-based paint needs to be discharged, the solenoid valve 13 is opened and the water-based paint is discharged through the discharge port 12.

[0022] As a further implementation of this embodiment, such as Figure 1-4As shown, an exhaust fan 11 is installed at the front end of the top of the cover 10, and a cooling box 8 is installed at the rear end of the top of the cover 10. Heat dissipation fins 9 are installed on both sides of the cooling box 8, arranged at equal intervals. A steam pipe 7 is installed at the output end of the exhaust fan 11. A serpentine condenser tube 19 is installed inside the cooling box 8. The rear end of the steam pipe 7 passes through the top of the cooling box 8 and is fixedly connected to the top of the condenser tube 19. The exhaust fan 11 draws out the water evaporated during the heating of the water-based paint and transports it through the steam pipe 7 to the condenser tube 19 inside the cooling box 8. A water inlet 23 is inserted into the rear end of the bottom of the cooling box 8. The bottom end of the water inlet 23 extends through the cover 10 into the interior of the inner cylinder 4. The bottom of the condenser tube 19... The end and the top of the inlet 23 are fixedly connected. The evaporated water is condensed into water through heat exchange with the condensate in the cooling box 8. Finally, the condensate is reintroduced into the water-based paint in the device through the inlet 23. The cooling box 8 is cooled by the heat dissipation fins 9 to avoid the condensate from overheating and affecting the heat exchange efficiency. The top of the rear end of the cooling box 8 is provided with a filling port 15, and the bottom of the rear end of the cooling box 8 is provided with a drain port 14. The drain port 14 and the filling port 15 are symmetrically arranged at the rear end of the cooling box 8 to avoid excessive water loss when heating the water-based paint. The water added after condensation can also be used to cool the inside of the device to prevent the water-based paint from overheating. This achieves the effect of preventing the water-based paint from overheating and avoiding the performance degradation of the water-based paint.

[0023] When the water-based paint is heated by the electric heating plate 22 to prevent it from curing, the exhaust fan 11 is activated to draw out the water evaporated during heating and transport it through the steam pipe 7 to the condenser pipe 19 in the cooling box 8. The evaporated water is condensed into water through heat exchange with the condensate in the cooling box 8. Finally, the condensate is reintroduced into the water-based paint in the device through the water inlet 23 to avoid excessive water loss when heating the water-based paint. At the same time, the cooling box 8 is cooled by the heat dissipation fins 9.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, a scraping assembly is provided at both ends of the rotating shaft 16. The scraping assembly includes a scraper 21, which is located at both ends inside the inner cylinder 4. A connecting rod 18 is provided between the stirring rods 17 at both ends of the outer side of the rotating shaft 16. One end of the connecting rod 18 is fixedly connected to the inner side of the scraper 21. When the rotating shaft 16 rotates, the connecting rod 18 drives the scraper 21 to rotate on the inner side wall of the inner cylinder 4 and the bottom of the outer cylinder 1, so as to prevent the water-based paint adhering to the inner wall of the device from curing. At the same time, it prevents the water-based paint on the inner wall of the device from being overheated and losing its performance. It can also scrape off and discharge the water-based paint adhering to the inner wall of the device when the water-based paint is discharged. A protective rubber strip 24 is provided on the outer side of the scraper 21. The protective rubber strip 24 is in contact with the inner side wall of the inner cylinder 4 and the bottom of the outer cylinder 1. The protective rubber strip 24 can prevent the scraper 21 from scratching the bottom of the outer cylinder 1 and the inner wall of the inner cylinder 4, thus affecting the service life of the device.

[0025] When the rotating shaft 16 rotates, it drives the scraper 21 to rotate on the inner side wall of the inner cylinder 4 and the inner bottom of the outer cylinder 1 through the connecting rod 18. This scrapes off the water-based paint adhering to the inner wall of the device, allowing it to be fully stirred and preventing the water-based paint on the inner wall of the device from being overheated. When discharging the water-based paint, the water-based paint adhering to the inner wall of the device can also be scraped off and discharged. The protective rubber strip 24 can prevent the scraper 21 from scratching the inner bottom of the outer cylinder 1 and the inner wall of the inner cylinder 4.

[0026] Specific working principle:

[0027] When using the anti-curing device, water-based paint is first fed into the device through the feed inlet 6, and the electric heating plate 22 is turned on to heat the water-based paint to prevent it from curing. Simultaneously, the drive motor 5 is activated to drive the rotating shaft 16, which in turn rotates the stirring rod 17 to further agitate the water-based paint and prevent curing. As the rotating shaft 16 rotates, it drives the scraper 21 via the connecting rod 18 to rotate on the inner side wall of the inner cylinder 4 and the bottom of the outer cylinder 1, scraping off the water-based paint adhering to the inner wall of the device to ensure thorough agitation and prevent overheating. The protective rubber strip 24 prevents the scraper 21 from damaging the bottom of the outer cylinder 1 and the inner wall of the inner cylinder 4. Simultaneously, a temperature sensor... 25. Monitor the temperature inside the device to ensure that the temperature inside the device is maintained at a suitable level. At the same time, start the exhaust fan 11 to draw out the water evaporated during heating and transport it through the steam pipe 7 to the condenser pipe 19 inside the cooling box 8. The evaporated water is condensed into water through heat exchange with the condensate in the cooling box 8. Finally, the condensate is reintroduced into the water-based paint inside the device through the water inlet 23 to avoid excessive water loss when heating the water-based paint. At the same time, the cooling fins 9 dissipate heat from the cooling box 8. When it is necessary to discharge the water-based paint, open the solenoid valve 13 to discharge the water-based paint through the discharge port 12. At the same time, use the scraper 21 to scrape off and discharge the water-based paint adhering to the inner wall of the device.
