Description

Technical Field

[0001] This utility model relates to the field of paint storage technology, and in particular to a paint storage device. Background Technology

[0002] Coatings are applied to the surface of objects to be protected or decorated, forming a continuous, firmly adhering film. They are typically viscous liquids made primarily of resins, oils, or emulsions, with or without pigments and fillers, and with appropriate additives, prepared using organic solvents or water. Coatings belong to the category of organic chemical polymer materials, and the resulting film is a type of polymer compound. According to modern classifications of chemical products, coatings fall under the category of fine chemical products. Modern coatings are gradually becoming a type of multifunctional engineering material and an important sector within the chemical industry.

[0003] Existing paint storage devices often have a simple structure, making the stored paint susceptible to curing or delamination due to environmental factors, affecting its performance. Furthermore, due to the high viscosity of the paint, traditional storage devices frequently experience poor discharge during the discharging process. Therefore, effectively preventing paint curing during storage and improving discharge efficiency have become urgent technical problems to be solved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing paint storage devices, which have relatively simple structures and are prone to solidification or delamination due to environmental factors during paint storage, affecting their performance. Furthermore, traditional storage devices often experience poor discharge due to the high viscosity of the paint during the discharge process. This invention provides a paint storage device.

[0005] The purpose of this utility model is achieved through the following technical solution: a paint storage device, including a storage tank, an inlet pipe installed on the top of the storage tank, a sealing cap installed on the inlet pipe, a discharge pipe installed at the bottom of the storage tank, a flow control valve installed on the discharge pipe, the flow control valve is set to adjust the flow rate of the paint according to the demand, an air pump is installed on the storage tank, the output end of the air pump is connected to the discharge pipe through an air pipe, and a pressure regulator connected to the air pump is installed on the air pipe.

[0006] A servo motor is installed on the top of the storage tank. The power output end of the servo motor extends into the storage tank and is equipped with a stirring shaft with stirring blades.

[0007] An air pump and air pipe are used to improve the fluidity of the coating in the discharge pipe by external pressurization, thereby avoiding the problem of poor discharge. A pressure regulator is set up to adjust the output pressure according to the viscosity of the coating to meet the discharge requirements of coatings with different viscosities. A servo motor drives the stirring blades on the stirring shaft to periodically stir the coating stored in the storage tank to prevent the coating from separating due to long-term standing. At the same time, the servo motor can adjust the speed of the stirring shaft and stirring blades to adapt to the stirring requirements of coatings with different viscosities.

[0008] A further technical solution involves installing an insulation layer on the outer surface of the storage tank, with a heating element installed between the tank and the insulation layer. A temperature sensor is installed on the inner wall of the tank, and the heating element is connected to the temperature sensor. By coordinating the heating element and the temperature sensor, the sensor monitors the temperature of the coating inside the storage tank in real time and controls the operation of the heating element according to a set temperature range. When the temperature is lower than the set value, the heating element activates to raise the temperature; when the temperature reaches the set value, the heating element stops working, ensuring that the coating is always at a suitable storage temperature. Simultaneously, the insulation layer surrounding the outer wall of the storage tank and the heating element reduces heat loss, thereby improving temperature control efficiency.

[0009] A further technical solution involves a mixing blade comprising main blades and auxiliary blades. The main blades are spirally distributed along the axial direction of the mixing shaft, while the auxiliary blades are perpendicular to the main blades and radially distributed along the mixing shaft. The bottom of the mixing shaft is connected to a bearing housing, and a sealing ring is provided on the outside of the bearing housing. By synergistically combining the main blades and auxiliary blades, the mixing effect of the coating can be enhanced, while the sealing ring on the outside of the bearing housing provides sealing protection for the bearing housing.

[0010] A further technical solution is to install a liquid level sensor on the inner wall of the storage tank. The liquid level sensor is connected to an external control system. By setting the liquid level sensor, the liquid level height of the coating can be monitored in real time. The liquid level sensor is connected to the external control system through a signal line, which makes it easy for operators to know the amount of coating stored.

[0011] A further technical solution is to install an exhaust valve on the top of the storage tank. The exhaust valve is used to release the gas in the storage tank during the coating injection or stirring process, so as to avoid excessive pressure affecting the normal operation of the device.

[0012] A further technical solution is that the sealing cap is threadedly connected to the feed pipe. The sealing cap is used to seal the feed pipe, and a removable filter screen is installed inside the feed pipe. By setting the filter screen, impurities in the paint can be intercepted. At the same time, the filter screen is removable, which makes it easy to replace and clean the filter screen.

[0013] A further technical solution is to provide a fluoropolymer coating on the inner wall of the storage tank. The fluoropolymer coating on the inner wall of the storage tank can effectively improve the corrosion resistance of the inner wall of the storage tank, while significantly reducing paint adhesion and avoiding the phenomenon of paint sticking to the wall.

[0014] This invention has the following advantages: It uses an air pump and air pipe to improve the fluidity of the coating in the discharge pipe by applying external pressure, thus avoiding problems with poor discharge. A pressure regulator allows adjustment of the output pressure according to the viscosity of the coating to meet the discharge requirements of coatings of different viscosities. A servo motor drives the stirring blades on the stirring shaft to periodically stir the coating stored in the storage tank, preventing the coating from separating due to prolonged standing. Simultaneously, the servo motor can adjust the speed of the stirring shaft and stirring blades to adapt to the stirring requirements of coatings of different viscosities. Attached Figure Description

[0025] like Figures 1-3 As shown, a paint storage device includes a storage tank 1, a feed pipe 2 installed on the top of the storage tank 1, a sealing cap 12 installed on the feed pipe 2, a discharge pipe 3 installed at the bottom of the storage tank 1, a flow control valve 4 installed on the discharge pipe 3, the flow control valve 4 is set to adjust the flow rate of the paint according to the demand, an air pump 13 is installed on the storage tank 1, the output end of the air pump 13 is connected to the discharge pipe 3 through an air pipe 14, a pressure regulator 15 connected to the air pump 13 is installed on the air pipe 14, and a servo motor 8 is installed on the top of the storage tank 1, the power output end of the servo motor 8 extends into the storage tank 1 and is equipped with a stirring shaft 9, and stirring blades are installed on the stirring shaft 9.

[0026] An air pump 13 is configured in conjunction with an air pipe 14 to improve the fluidity of the coating in the discharge pipe 3 by external pressurization, thereby avoiding the problem of poor discharge in the discharge pipe 3. A pressure regulator 15 is configured to adjust the output pressure according to the viscosity of the coating to meet the discharge requirements of coatings with different viscosities. A servo motor 8 is configured to drive the stirring blades on the stirring shaft 9 to periodically stir the coating stored in the storage tank 1 to prevent the coating from stratifying due to long-term standing. At the same time, the servo motor 8 can adjust the speed of the stirring shaft 9 and the stirring blades to adapt to the stirring requirements of coatings with different viscosities.

[0027] An insulation layer 6 is installed on the outer surface of the storage tank 1. A heating element 7 is installed between the storage tank 1 and the insulation layer 6. A temperature sensor is installed on the inner wall of the storage tank 1. The heating element 7 is connected to the temperature sensor. By coordinating the heating element 7 and the temperature sensor, the temperature sensor monitors the temperature of the coating inside the storage tank 1 in real time and controls the working state of the heating element 7 according to the set temperature range. When the temperature is lower than the set value, the heating element 7 is activated to raise the temperature; when the temperature reaches the set value, the heating element 7 stops working, ensuring that the coating is always at a suitable storage temperature. At the same time, the insulation layer 6 covering the outer wall of the storage tank 1 and the heating element 7 can reduce heat loss, thereby improving temperature control efficiency.

[0028] The stirring blades include main blades 10 and auxiliary blades 11. The main blades 10 are spirally distributed along the axial direction of the stirring shaft 9, and the auxiliary blades 11 are perpendicular to the main blades 10 and radially distributed along the stirring shaft 9. The bottom of the stirring shaft 9 is connected to the bearing housing 16, and a sealing ring is provided on the outside of the bearing housing 16. By setting the main blades 10 and auxiliary blades 11 to work together, the mixing effect of the coating can be enhanced, and the sealing ring on the outside of the bearing housing 16 provides a sealing and protection function for the bearing housing 16.

[0029] A liquid level sensor 17 is installed on the inner wall of the storage tank 1. The liquid level sensor 17 is connected to an external control system. The liquid level sensor 17 is used to monitor the liquid level of the coating in real time. The liquid level sensor 17 is connected to the external control system through a signal line, which makes it easy for operators to know the amount of coating stored.

[0030] An exhaust valve 5 is installed on the top of the storage tank 1. The exhaust valve 5 is used to release the gas in the storage tank 1 during the coating injection or stirring process to avoid excessive pressure affecting the normal operation of the device.

[0031] The sealing cap 12 is threadedly connected to the feed pipe 2. The sealing cap 12 is used to seal the feed pipe 2. A removable filter screen 18 is installed inside the feed pipe 2. By setting the filter screen 18, impurities in the paint can be intercepted. At the same time, the filter screen 18 is removable, which makes it easy to replace and clean the filter screen 18.

[0032] The inner wall of storage tank 1 is coated with a fluoropolymer. The fluoropolymer coating on the inner wall of storage tank 1 can effectively improve the corrosion resistance of the inner wall of storage tank 1, and at the same time significantly reduce the adhesion of the coating, thus avoiding the phenomenon of coating sticking to the wall.

[0033] The working process of this utility model is as follows: First, the operator injects the paint into the storage tank 1 through the sealing cap 12 on the feed pipe 2. After the paint enters the storage tank 1, the liquid level sensor 17 monitors the liquid level in real time and transmits the data to the external control system so that the operator can monitor the storage volume. At the same time, the exhaust valve 5 automatically opens during the paint injection process to release the gas in the storage tank 1, preventing excessive pressure from affecting the normal operation of the device. After the paint injection is completed, the feed pipe 2 is closed through the sealing cap 12, and the exhaust valve 5 is closed to ensure that a closed environment is formed inside the storage tank 1.

[0034] Subsequently, the temperature control system begins operation. A temperature sensor monitors the temperature of the coating inside storage tank 1 in real time and transmits the collected data to heating element 7. If the temperature falls below the set value, heating element 7 activates to raise the temperature inside storage tank 1; when the temperature reaches the set range, heating element 7 stops operating. An insulation layer 6, made of polyurethane material and 20mm to 30mm thick, surrounds storage tank 1 and heating element 7, effectively reducing heat loss and thus improving temperature control efficiency. This process ensures the coating remains at a suitable storage temperature, preventing curing due to excessively low temperatures.

[0035] Next, the stirring assembly is activated. The servo motor 8 drives the stirring shaft 9 to rotate, causing the main blades 10 and auxiliary blades 11 to periodically stir the coating. The main blades 10 are spirally distributed along the axial direction of the stirring shaft 9, while the auxiliary blades 11 are perpendicular to the main blades 10 and radially distributed along the stirring shaft 9. Together, they enhance the mixing effect of the coating. The bottom of the stirring shaft 9 is connected to a bearing housing 16, which is equipped with a sealing ring. The rotational speed of the servo motor 8 can be adjusted from 50 rpm to 150 rpm according to the viscosity of the coating to meet the stirring requirements of coatings with different viscosities. Through the continuous operation of the stirring assembly, the coating remains uniform in the storage tank 1, preventing stratification caused by prolonged standing.

[0036] When discharge is required, the paint is discharged from the discharge pipe 3. The flow control valve 4 adjusts the flow rate of the paint according to actual needs to ensure a smooth and controllable discharge process. The discharge pipe 3 is made of stainless steel, and its inner wall is polished with a surface roughness of less than 0.8μm, which effectively reduces the adhesion and residue of paint during the transportation process.

[0037] Simultaneously, the pressure-assisted components begin to operate. Air pump 13 provides additional pressure to discharge pipe 3 via air pipe 14, and pressure regulator 15 adjusts the output pressure according to the viscosity of the coating to meet the discharge requirements of coatings with different viscosities. The pressurizing effect of air pump 13 significantly improves the fluidity of the coating, solving the problem of poor discharge caused by excessively high coating viscosity in traditional storage devices. Furthermore, the precise control of pressure regulator 15 ensures the stability of the discharge process, preventing excessive or insufficient pressure from affecting discharge efficiency.

[0038] Throughout the entire process, all components work together to effectively prevent the coating from curing and delamination during storage. The temperature control component, through the heating element 7 and the temperature sensor, maintains the appropriate storage temperature for the coating; the stirring component, through the coordinated action of the main blade 10 and the auxiliary blade 11, ensures the uniformity of the coating; the air pump 13, air pipe 14, and pressure regulator 15 work together to significantly improve discharge efficiency. The connections between the components are clear, and the structural design is reasonable, capable of meeting the diverse needs of actual production.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
