Technical Field

[0001] This application relates to the field of quick-drying coating formulation technology, and more particularly to an automatic proportioning and sealing mixing system for quick-drying coatings. Background Technology

[0002] Multi-component fast-drying coatings need to be mixed and prepared on-site before use. The raw materials of each component are weighed, mixed, and stirred evenly before being used by the spraying equipment.

[0003] In related technologies, ingredients are weighed manually or mixed using a conventional automatic proportioning system. The automatic proportioning system includes multiple separate raw material storage devices and a mixing device. The raw material storage devices are pumped together into the mixing device in proportion for mixing.

[0004] However, the aforementioned batching system cannot achieve precise batching, which in turn affects the user's needs. Summary of the Invention

[0064] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0065] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0066] As mentioned in the background section, existing quick-drying coatings are prepared in two ways before use: either manually weighing and mixing the ingredients, or using a conventional automatic mixing system. The automatic mixing system includes multiple separate raw material storage devices and a mixing device. The raw materials from each storage device are pumped together into the mixing device in proportion for mixing. However, due to the lack of viscosity detection, timely viscosity feedback cannot be provided, thus failing to meet the requirements for precise mixing ratios and affecting the coating's performance. Furthermore, because quick-drying coatings have a short pot life after mixing and are prone to oxidation upon contact with air, the existing mixing method involving exposure to air also negatively impacts the coating's performance.

[0067] To address the aforementioned problems in existing quick-drying paint mixing processes, this application provides an automatic proportioning and sealing mixing system for quick-drying paints. The system includes a first sealed storage device, at least one second sealed storage device, a thinner storage device, a sealed mixing device, and a control unit. The first sealed storage device includes a first sealed tank and a first detection element. The first sealed tank is connected to the sealed mixing device via a first pipeline, and a first flow control element is installed on the first pipeline to accurately control the delivery amount of a first raw material. The second sealed storage device is connected to the sealed mixing device via a second pipeline, and a second flow control element is installed on the second pipeline to accurately control the delivery amount of a second raw material. The thinner storage device is connected to the first sealed tank via a third pipeline, and a third flow control element is installed on the third pipeline to accurately control the delivery amount of the thinner. The first detection element, the first flow control element, the second flow control element, and the third flow control element are all electrically connected to the control unit. The first sealed container and the second sealed storage device are used to store the first raw material and the second raw material, respectively. A first detection element detects the viscosity of the first raw material in the first sealed container, and a control unit controls the opening of a third flow control element to allow the diluent storage device to precisely deliver diluent to the first sealed container, thereby adjusting the viscosity of the first raw material in the first sealed container to a preset viscosity. Then, the control unit controls the opening of the first and second flow control elements to allow the first sealed container and the second sealed storage device to precisely deliver the first raw material and the second raw material to a sealed mixing device in a preset ratio, and mix them to achieve precise coating formulation.

[0068] The technical solution of this application will be described in detail below with reference to the accompanying drawings and several specific embodiments. It is understood that the following embodiments can be combined or used individually.

[0069] Please refer to Figures 1-3 As shown, the automatic proportioning and sealing mixing system for fast-drying coatings provided in this embodiment includes a first sealed storage device 100, at least one second sealed storage device 200, a diluent storage device 300, a sealed mixing device 400, and a control unit 500.

[0070] The first sealed storage device 100 includes a first sealed container 110 and a first detection element 120. The first sealed container 110 is connected to the sealed mixing device 400 through a first pipeline 130, and a first flow control element 140 is provided on the first pipeline 130. The second sealed storage device 200 is connected to the sealed mixing device 400 through a second pipeline 210, and a second flow control element 220 is provided on the second pipeline 210. The diluent storage device 300 is connected to the first sealed container 110 through a third pipeline 310, and a third flow control element 320 is provided on the third pipeline 310. The first detection element 120, the first flow control element 140, the second flow control element 220, and the third flow control element 320 are all electrically connected to the control unit 500.

[0071] The first sealed container 110 and the second sealed storage device 200 are used to store the first raw material and the second raw material, respectively. The first detection element 120 is used to detect the viscosity of the first raw material, and the control unit 500 controls the third flow control element 320 to open, so that the diluent storage device 300 delivers diluent to the first sealed container 110 to adjust the first raw material to a preset viscosity.

[0072] The control unit 500 is also used to control the opening of the first flow control element 140 and the second flow control element 220, so that the first sealed tank 110 and the second sealed storage device 200 respectively deliver the first raw material and the second raw material to the sealed mixing device 400 in a preset ratio.

[0073] In this embodiment, the first sealed storage device 100 is used to store the first raw material and also to detect the viscosity of the first raw material. The second sealed storage device 200 is used to store the second raw material; there may be one or more second sealed storage devices 200. The diluent storage device 300 is used to store diluent. The sealed mixing device 400 is used to seal and mix the first and second raw materials, and upon completion of mixing, it is connected to a spraying device via a pipeline for spraying. The control unit 500 is at least used to control the viscosity detection of the first raw material, control the dilution and preparation of the first raw material, and control the ratio of the first and second raw materials.

[0074] The first sealed storage device 100 includes at least a first sealed tank 110 and a first detection element 120. The first sealed tank 110 is used to store the first raw material. A feeding port can be opened on the first sealed tank 110. The bottom of the first sealed tank 110 can be connected to the sealed mixing device 400 through a first pipeline 130. A first flow control element 140, such as a flow pump or flow valve with metering function, is set on the first pipeline 130 to accurately control the flow rate of the first raw material passing through the first pipeline 130.

[0075] The second sealed storage device 200 can also be a sealed tank or other container, and a feeding port can be opened at the top. The bottom of the second sealed storage device 200 can be connected to the sealed mixing device 400 through the second pipeline 210. The flow rate of the second raw material passing through the second pipeline 210 can be precisely controlled by setting a second flow control component 220, such as a flow pump or flow valve with metering function, on the second pipeline 210.

[0076] The diluent storage device 300 can also be a sealed container or other container, and a feeding port can also be opened at the top. The diluent storage device 300 can be connected to the first sealed container 110 through the third pipeline 310. A third flow control device 320, such as a flow pump or flow valve with metering function, is set on the third pipeline 310 to accurately control the flow rate of the diluent passing through the third pipeline 310.

[0077] The first detection element 120, the first flow control element 140, the second flow control element 220, and the third flow control element 320 are all electrically connected to the control unit 500 for data exchange. The control unit 500 can be a PLC-based control unit. The control unit 500 controls the duration and flow rate of the first flow control element 140, the second flow control element 220, and the third flow control element 320, respectively. For example, it can control a large flow rate for a short period or a small flow rate for a long period.

[0078] The first detection element 120 is used to detect the current viscosity of the first raw material in the first sealed container 110 and promptly feed it back to the control unit 500. Therefore, the first detection element 120 can be a viscosity sensor, viscometer, etc.

[0079] Specifically, the first step involves placing the first raw material into the first sealed container 110, placing the second raw material into the second sealed storage device 200, and placing the diluent into the diluent storage device 300. The first detection element 120 detects the viscosity of the first raw material in the first sealed container 110 and promptly feeds back the current viscosity value to the control unit 500. The control unit 500 then controls the third flow control element 320 to open, causing the diluent storage device 300 to deliver diluent to the first sealed container 110, thereby adjusting the viscosity of the first raw material in the first sealed container 110 to a preset viscosity.

[0080] It is worth noting that if the current viscosity differs significantly from the preset viscosity, the control unit 500 can increase the opening of the third flow control element 320 to increase the flow rate in the third pipeline 310, thereby rapidly adding the diluent. Conversely, if the current viscosity differs only slightly from the preset viscosity, the control unit 500 can decrease the opening of the third flow control element 320 to decrease the flow rate in the third pipeline 310, thereby reducing the amount of diluent added. Once the current viscosity matches the preset viscosity, the control unit 500 closes the third flow control element 320. This ensures the accuracy of diluting the first raw material.

[0081] In the second step, the control unit 500 controls the first flow control element 140 and the second flow control element 220 to open, and simultaneously controls the flow rate and opening duration of both, so that the first sealed tank 110 delivers the first raw material to the sealed mixing device 400 through the first pipeline 130 in a preset ratio, and the second sealed storage device 200 delivers the second raw material to the sealed mixing device 400 through the second pipeline 210 in a preset ratio, so that they are mixed together in the sealed mixing device 400 for use with the spraying equipment.

[0082] It is worth noting that by precisely diluting the first raw material before mixing it evenly with the second raw material in a sealed mixing device 400, an ideal ratio can be quickly achieved, allowing for timely use by the spraying equipment. Compared to existing technologies that add all raw materials to the mixing device together, this step-by-step approach allows for more precise control of the raw material ratios and ensures uniform and controllable mixing. Furthermore, mixing in a sealed environment avoids contact with air, thus preventing oxidation of the coating and ensuring its performance.

[0083] Understandably, the automatic proportioning and sealing mixing system for quick-drying coatings provided in this embodiment includes a first sealed storage device 100, at least one second sealed storage device 200, a diluent storage device 300, a sealed mixing device 400, and a control unit 500. The first sealed storage device 100 includes a first sealed tank 110 and a first detection element 120. The first sealed tank 110 is connected to the sealed mixing device 400 via a first pipeline 130, and a first flow control element 140 is installed on the first pipeline 130 to accurately control the delivery amount of the first raw material. The second sealed storage device 200 is connected to the sealed mixing device 400 via a second pipeline 210, and a second flow control element 220 is installed on the second pipeline 210 to accurately control the delivery amount of the second raw material. The diluent storage device 300 is connected to the first sealed tank 110 via a third pipeline 310, and a third flow control element 320 is installed on the third pipeline 310 to accurately control the delivery amount of the diluent. The first detection element 120, the first flow control element 140, the second flow control element 220, and the third flow control element 320 are all electrically connected to the control unit 500. The first sealed container 110 and the second sealed storage device 200 are used to store the first raw material and the second raw material, respectively. The first detection element 120 detects the viscosity of the first raw material in the first sealed container 110, and the control unit 500 controls the third flow control element 320 to open, allowing the diluent storage device 300 to precisely deliver diluent to the first sealed container 110, thereby adjusting the viscosity of the first raw material in the first sealed container 110 to a preset viscosity. Then, the control unit 500 controls the first flow control element 140 and the second flow control element 220 to open, allowing the first sealed container 110 and the second sealed storage device 200 to precisely deliver the first raw material and the second raw material to the sealed mixing device 400 according to a preset ratio, and mix them to achieve precise coating formulation.

[0084] In one possible design, such as Figure 1 As shown, the first detection element 120 is a viscosity sensor, which is installed inside the first sealed container 110. Figure 3 As shown, the first flow control component 140, the second flow control component 220 and the third flow control component 320 all include a flow pump and a solenoid valve. The flow pump and the solenoid valve are electrically connected to the control unit 500. The control unit 500 is used to control the opening time of the flow pump and the opening degree of the solenoid valve according to the viscosity of the first raw material.

[0085] Specifically, the measuring end of the viscosity sensor is located inside the first sealed container 110 and extends below the liquid surface of the first raw material. The body of the viscosity sensor is located inside the first sealed container 110 and fixed to the outer wall. The viscosity sensor is electrically connected to the control unit 500. This facilitates accurate detection of the viscosity data of the first raw material and allows for feedback to the control unit 500.

[0086] Furthermore, the flow pump and solenoid valve are integrated into one unit. The control unit 500 can precisely control the duration and flow rate of the flow pump by controlling the opening degree of the solenoid valve. The specific models of the flow pump and solenoid valve can be determined according to actual needs, and no specific limitation is made in this embodiment.

[0087] In order to achieve thorough mixing and dilution of the first raw material in the first sealed container 110, such as Figure 1 As shown, in this embodiment, a first magnetic stirrer 150 is also provided inside the first sealed container 110. Exemplarily, the first magnetic stirrer 150 includes a base and a magnetic stir bar. The base is located at the bottom outside the first sealed container 110, and the magnetic stir bar is placed inside the first sealed container 110. The base provides a rotating magnetic field to drive the magnetic stir bar to rotate.

[0088] In this way, the first raw material in the first sealed container 110 can be fully stirred by the magnetic stir bar, and compared with conventional stirring paddles, this stirring method will not affect the sealing performance of the first sealed container 110.

[0089] In order to monitor the liquid level and temperature of the first raw material in the first sealed tank 110, combined with Figure 1 , Figure 3 As shown, in this embodiment, a liquid level sensor 160 and a temperature sensor 170 are also provided inside the first sealed container 110. Both the liquid level sensor 160 and the temperature sensor 170 are electrically connected to the control unit 500. The liquid level sensor 160 is used to detect the liquid level inside the first sealed container 110, and the temperature sensor 170 is used to detect the temperature inside the first sealed container 110.

[0090] Specifically, the measuring parts of the level sensor 160 and the temperature sensor 170 are located inside the first sealed container 110 and are in contact with the liquid surface therein. For example, when the liquid level in the first sealed container 110 exceeds the maximum limit position, the control unit 500 issues an alarm and controls the third flow control element 320 to shut down; when the liquid level in the first sealed container 110 is below the minimum limit position, the control unit 500 issues an alarm and controls the first flow control element 140 to shut down. Similarly, when the temperature inside the first sealed container 110 exceeds the maximum limit temperature, the control unit 500 issues an alarm to stop stirring or take cooling measures.

[0091] In this way, the liquid level and temperature of the first raw material in the first sealed tank 110 can be monitored in real time by the liquid level sensor 160 and the temperature sensor 170, and the feedback is sent to the control unit 500 so as to control and regulate the first flow control element 140, the second flow control element 220 and the third flow control element 320. The specific models of the liquid level sensor 160 and the temperature sensor 170 can be determined according to actual needs, and are not specifically limited in this embodiment.

[0092] In one possible design, the sealed mixing device 400 includes a sealed housing 410, within which a labyrinth mixing channel 411 runs from top to bottom. This allows the first and second raw materials to enter the sealed housing 410 and, as they pass through the labyrinth mixing channel 411, to collide and mix back and forth, resulting in more thorough and rapid mixing.

[0093] Among them, the path of the maze-like mixed passage 411 is distributed in a serpentine pattern from top to bottom, such as... Figure 2 As shown by the dashed lines, the maze-like mixed passage 411 can be a single passage or multiple passages arranged side by side.

[0094] Specifically, such as Figure 2 As shown, in this embodiment, the sealed mixing device 400 further includes a partition 420 and a second magnetic stirrer 430. The partition 420 is inclinedly disposed inside the sealed housing 410, and several partitions 420 are spaced apart from top to bottom. A material outlet 412 is provided between the lower side of the partition 420 and the inner wall of the sealed housing 410. Two adjacent material outlets 412 are staggered to form a labyrinth mixing channel 411. The second magnetic stirrer 430 is located at the bottom of the labyrinth mixing channel 411.

[0095] For example, from top to bottom, the first partition 420 is lower on the left and has the first material passage 412, the second partition 420 is lower on the right and has the second material passage 412, and so on, thus forming a serpentine maze mixing channel 411. The specific number and inclination of the partitions 420 are not specifically limited in this embodiment.

[0096] Furthermore, the second magnetic stirrer 430 can also be similar to the first magnetic stirrer 150. That is, the second magnetic stirrer 430 can also include a base and a magnetic stir bar. The base is located at the bottom outside the sealed housing 410, and the magnetic stir bar is placed at the bottom of the labyrinth mixing channel 411, that is, at the lower part of the bottommost partition 420. The base provides a rotating magnetic field to drive the magnetic stir bar to rotate. In this way, the first and second raw materials in the labyrinth mixing channel 411 can be fully mixed by the magnetic stir bar, and compared with conventional stirring paddles, this mixing method will not affect the sealing performance of the labyrinth mixing channel 411.

[0097] Optionally, in this embodiment, as Figure 1As shown, a first control valve 180 and a first check valve 190 are provided on the first pipeline 130. The first control valve 180 is electrically connected to the control unit 500. When the control unit 500 controls the first flow control element 140 to open, the control unit 500 simultaneously controls the first control valve 180 to open. The first check valve 190 is used to allow the first pipeline 130 to flow unidirectionally into the sealed mixing device 400.

[0098] This configuration allows for the complete opening or closing of the first pipeline 130 via the first control valve 180, and prevents backflow via the first check valve 190. Specifically, the first control valve 180 and the first check valve 190 are spaced apart on the first pipeline 130, which connects to the sealing mixing device 400 via the first flow control element 140. The first control valve 180 can be an electric ball valve, an electric shut-off valve, etc., so that the control unit 500 can control the opening or closing of the first control valve 180.

[0099] The second pipeline 210 is equipped with a second control valve 230 and a second check valve 240. The second control valve 230 is electrically connected to the control unit 500. When the control unit 500 controls the second flow control element 220 to open, the control unit 500 also controls the second control valve 230 to open. The second check valve 240 is used to allow the second pipeline 210 to flow unidirectionally into the sealed mixing device 400.

[0100] Similarly, the second control valve 230 controls the complete opening or complete closing of the second pipeline 210, and the second check valve 240 prevents backflow. Specifically, the second control valve 230 and the second check valve 240 are spaced apart on the second pipeline 210 from the second flow control element 220 to the sealed mixing device 400. The second control valve 230 can also be an electric ball valve, an electric shut-off valve, etc., so that the control unit 500 can control the second control valve 230 to open or close.

[0101] The specific models of the first control valve 180, the first check valve 190, the second control valve 230, and the second check valve 240 are not specifically limited in this embodiment.

[0102] To further prevent the oxidation of the first and second raw materials, such as Figure 1 As shown, in this embodiment, both the first sealed container 110 and the second sealed storage device 200 contain inert gas, and both the first sealed container 110 and the second sealed storage device 200 are provided with inert gas inlet 250, through which inert gas is supplied to the first sealed container 110 or the second sealed storage device 200 respectively.

[0103] This configuration allows inert gas to be filled into the first sealed container 110 and the second sealed storage device 200 through the inert gas inlet 250, thereby isolating them from air and preventing the raw materials from deteriorating. The inert gas can be nitrogen or similar.

[0104] Optionally, such as Figure 1 As shown, in this embodiment, the diluent storage device 300 is connected to the sealed mixing device 400 via a fourth pipeline 330, and a third control valve 340 is provided on the fourth pipeline 330. The third control valve 340 is electrically connected to the control unit 500. The control unit 500 is also used to control the third control valve 340 to open, so that the diluent storage device 300 delivers diluent to the sealed mixing device 400 for cleaning the sealed mixing device 400.

[0105] In one example, one end of the fourth pipe 330 is connected to the bottom of the diluent storage device 300, and the other end of the fourth pipe 330 has a first branch pipe and a second branch pipe. The first branch pipe is connected to the first pipe 130, and the second branch pipe is connected to the second pipe 210. A third control valve 340 is installed on the fourth pipe 330. Thus, when the third control valve 340 is opened, the diluent storage device 300 enters the sealed mixing device 400 through the fourth pipe 330, the first branch pipe, and the second branch pipe to achieve cleaning.

[0106] In another example (not shown in the figure), one end of the fourth pipe 330 is connected to the bottom of the diluent storage device 300, and the other end of the fourth pipe 330 is directly connected to the sealed mixing device 400. A third control valve 340 is installed on the fourth pipe 330. Thus, when the third control valve 340 is opened, the diluent storage device 300 directly enters the sealed mixing device 400 from the fourth pipe 330, achieving cleaning.

[0107] The third control valve 340 can be an electric ball valve, an electric shut-off valve, etc., so that the control unit 500 can control the opening or closing of the third control valve 340. It should be noted that when the third control valve 340 is open, the first pipeline 130 and the second pipeline 210 need to be closed to prevent the diluent from flowing back into the first sealed tank 110 or the second sealed storage device 200.

[0108] Optionally, such as Figure 1 As shown, in this embodiment, a fourth control valve 350 and a third check valve 360 ​​are provided on the third pipeline 310. The fourth control valve 350 is electrically connected to the control unit 500. When the control unit 500 controls the third flow control element 320 to open, the control unit 500 controls the fourth control valve 350 to open, and the third check valve 360 ​​is used to allow the third pipeline 310 to flow unidirectionally into the first sealed tank 110.

[0109] This configuration allows for the complete opening or closing of the third pipeline 310 via the fourth control valve 350, and prevents backflow via the third check valve 360. Specifically, the fourth control valve 350, the third flow control element 320, and the third check valve 360 ​​are arranged at intervals on the third pipeline 310 leading from the diluent storage device 300 to the first sealed tank 110. The fourth control valve 350 can be an electric ball valve, an electric shut-off valve, etc., so that the control unit 500 can control the opening or closing of the fourth control valve 350.
