Description

Technical Field

[0001] The invention relates to the technical field of paint stirring structures, in particular to an aerogel paint stirring device. Background Art

[0002] In the coating production process, the coating stirring structure refers to a physical structure that evenly mixes the coating raw materials through specific stirring equipment and operation methods. Its goal is to ensure the uniform distribution of coating components and achieve the required physical properties, such as rheology, viscosity, color, etc. Conventional coating stirring structures generally use mechanical stirring, magnetic stirring or high-speed shear stirring, which can effectively complete the uniform mixing of coatings, and a heating structure is set outside the coating stirring structure to meet the processing temperature requirements of different coatings.

[0003] However, when the conventional stirring structure is applied to aerogel coatings, the aerogel itself has extremely low density and high specific surface area, which is easily affected by temperature changes during the stirring process; specifically, when the temperature is too high, stirring will cause degradation or deformation of the organic components in the aerogel, thereby affecting its own structural stability; when the temperature is too low, the aerogel is prone to cracking or powdering during stirring, affecting the quality of the coating. For conventional heating structure settings, due to the low thermal conductivity of aerogel, the temperature in the middle area of ​​the stirring structure is difficult to control, affecting the overall quality of the aerogel.

[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0049] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0050] The present embodiment provides an aerogel coating stirring device, which is suitable for stirring colloids with low thermal conductivity such as aerogel coating. In the present embodiment, the structure of the aerogel coating stirring device is improved to ensure the production quality and stability of the aerogel coating.

[0051] like Figure 1 and Figure 2As shown, the aerogel coating stirring device in this embodiment includes a stirring shell 100, a stirring rod 200, an inner heating structure, an outer heating structure, a heating unit 300 and a heat translation device 400; wherein the stirring shell 100 forms a stirring chamber 101; the stirring rod 200 is arranged along a first direction and rotatably installed in the stirring chamber 101, and is installed with a plurality of stirring units 210 arranged along a second direction; the inner heating structure is arranged on the stirring rod 200; the outer heating structure is arranged on the stirring shell 100; wherein the stirring shell 100 is installed on a mounting frame 500, and a stirring motor 600 is installed on the stirring shell 100, and the stirring motor 600 is used to drive the stirring rod 200 to rotate, thereby driving the stirring unit 210 to make a circular motion, the above-mentioned first direction is the gravity direction, and the second direction is located in the radial direction of the circular motion.

[0052] Among them, the heating unit 300 is installed on the stirring unit 210 along the first direction and can slide relative to the stirring rod 200 along the second direction; the moving end of the heat translation device 400 is connected to the heating unit 300, and is used to drive the heating unit 300 to move to the lowest temperature area in the stirring chamber 101.

[0053] It can be understood that the aerogel coating stirring device in this embodiment forms a temperature field with inner and outer sides arranged relatively to each other by arranging an inner heating structure on the stirring rod 200 and an outer heating structure on the stirring shell 100. Since the thermal conductivity of the aerogel coating is low, the temperature field is arranged from the inside to the outside in a high temperature area-low temperature area-high temperature area, and cooperates with the heat translation device 400 to move the heating unit 300 to the lowest temperature area in the stirring chamber 101, so that the temperature of the temperature field tends to be uniform, thereby avoiding the stirring temperature of the aerogel being too high or too low, ensuring that the aerogel in the stirring chamber 101 is in the optimal temperature range during the entire stirring process, thereby preventing the degradation or deformation of the organic components of the aerogel caused by high temperature and the rupture or powdering of the aerogel caused by low temperature; ultimately improving the production quality and stability of the aerogel coating.

[0054] Furthermore, if Figures 3 to 6 As shown, an installation cavity 211 is formed in the stirring unit 210; the heat translation device 400 includes: a temperature sensor, a screw unit 410, a screw nut 420 and a motor unit 430; there are multiple temperature sensors, which are arranged on the stirring unit 210 at intervals along the second direction; the screw unit 410 is installed in the installation cavity 211 along the second direction; the screw nut 420 is sleeved outside the screw unit 410 and is threadedly connected to the screw unit 410; the motor unit 430 drives the screw nut 420 to move to the lowest temperature area in the stirring chamber 101 through the screw unit 410 and the screw nut 420; the heating unit 300 is connected to the screw nut 420.

[0055] It is understandable that the heat translation device 400 is equipped with a plurality of temperature sensors, which are arranged at intervals along the second direction of the stirring unit 210, and are used to detect the temperature changes at different positions in the stirring chamber 101 in real time. With the rotation of the stirring rod 200, the above arrangement can accurately obtain the temperature field in the stirring chamber 101. Due to the low thermal conductivity of the aerogel coating, the stirring chamber 101 is prone to local temperature unevenness; the temperature sensor can quickly sense the temperature distribution of each area in the stirring chamber 101 and identify the lowest temperature area in the stirring chamber 101. The heating unit 300 can be accurately moved to the lowest temperature area through the heat translation device 400, and additional heating compensation for the area can be achieved, thereby effectively balancing the overall temperature field. Specifically, the motor unit 430 can drive the heating unit 300 to move along the second direction through the screw pair composed of the screw unit 410 and the screw nut 420, thereby adjusting the position of the heating unit 300 on the stirring unit 210 along the second direction.

[0056] As a specific implementation, the screw unit 410 is rotatably connected to the stirring unit 210 along its axis; an avoidance space is formed in the middle of the stirring unit 210 corresponding to the screw unit 410, so that the screw unit 410 extends from the installation inner cavity 211 to the outside of the stirring unit 210; the screw nut 420 is sleeved on the middle of the screw unit 410; the stator of the motor unit 430 is fixedly connected to the installation inner cavity 211, and is arranged on the cavity wall of the installation inner cavity 211 away from the stirring rod 200; the rotor of the motor unit 430 is fixedly connected to the end of the screw unit 410; the heating unit 300 is fixedly connected to the screw nut 420, and is slidably connected to the stirring unit 210.

[0057] To facilitate the understanding of those skilled in the art, the stirring unit 210 can be "concave" shaped, and its avoidance space is located in the recess, so that both ends of the screw unit 410 are arranged in the installation cavity 211, so that the middle of the screw unit 410 can extend to the recess, that is, the avoidance space. At this time, the heating unit 300 and the screw nut 420 are both located outside the installation cavity 211, avoiding pollution or equipment loss during the stirring process. Specifically, the motor unit 430 drives the screw unit 410 to rotate, and the rotation of the screw unit 410 causes the screw nut 420 threadedly connected thereto to move linearly along the axis direction of the screw unit 410, thereby accurately adjusting the position of the heating unit 300. It should be pointed out that, in this embodiment, the motor unit 430 is arranged on the cavity wall of the installation cavity 211 away from the stirring rod 200, which can avoid the motor units 430 in each stirring unit 210 being integrated near the stirring rod 200, resulting in excessive heat accumulation inside the stirring cavity 101. The above-mentioned arrangement makes the arrangement of the motor units 430 more dispersed, thereby avoiding excessive local heat accumulation and avoiding affecting the production quality of the aerogel coating.

[0058] As a specific implementation method, Figures 3 to 6 As shown, the screw unit 410 is fixedly connected to the stirring unit 210 along its axis, and the screw unit 410 is located in the installation inner cavity 211; the installation inner cavity 211 is slidably connected to the motor mounting plate 440 along the second direction, and the motor unit 430 is a hollow motor, which is sleeved outside the screw unit 410, and the stator of the motor unit 430 is fixedly connected to the motor mounting plate 440, and the rotor of the motor unit 430 is fixedly connected to the screw nut 420; the heating unit 300 is fixedly connected to the motor unit 430. Among them, the hollow motor is ring-shaped.

[0059] Specifically, the screw unit 410 is fixedly connected to the stirring unit 210 along its axis, and the screw unit 410 passes through the installation cavity 211 and remains fixed, while the motor unit 430 is a hollow motor, which is sleeved outside the screw unit 410; the rotor of the motor unit 430 is fixedly connected to the screw nut 420, and when the motor unit 430 is started, its rotor drives the screw nut 420 to rotate, and then uses the screw pair to make the screw nut 420 slide along the axial direction of the screw unit 410, so as to achieve precise position adjustment of the heating unit 300 in the stirring chamber 101. The above arrangement sets the motor unit 430 in the middle area of ​​the stirring unit 210. On the one hand, it can use the heat generated by the motor unit 430 to work together with the heating unit 300 to adjust the temperature, optimize the heat transfer path, and ensure the energy efficiency and reliability of the entire stirring system; on the other hand, it can avoid the occurrence of heat superposition in the internal or edge areas to avoid overheating.

[0060] On the basis of the above embodiment, a connecting ring is inserted into the hollow hole of the motor unit 430, and the connecting ring is sleeved outside the screw unit 410, and a screw nut 420 is connected to each end of the connecting ring; a motor mounting plate 440 is installed on each side of the motor unit 430; the end of the heating unit 300 extending into the installation cavity 211 is located between the two motor mounting plates 440; the stirring unit 210 is provided with an avoidance chute 212 at a position corresponding to the heating unit 300, and the heating unit 300 is slidably connected with the groove wall of the avoidance chute 212; a sealing part 220 is also installed in the installation cavity 211, and the sealing part 220 is used to separate the installation cavity 211 from the stirring cavity 101. Through the above arrangement, the rotation of the motor unit 430 can be transmitted to the screw nut 420 in a more efficient and stable manner, thereby realizing precise adjustment of the heating unit 300. In addition, motor mounting plates 440 are respectively installed on both sides of the motor unit 430, and the motor mounting plates 440 provide additional support for the motor unit 430, ensuring that the motor unit 430 remains stable during operation, while avoiding vibration interference with the overall transmission process. The end of the heating unit 300 is restricted between the two motor mounting plates 440, which effectively fixes the position of the heating unit 300 and further reduces the possibility of its displacement during movement, thereby ensuring transmission accuracy and thermal regulation effect.

[0061] Specifically, the sealing part 220 includes a reeling unit 221 respectively arranged at both ends of the installation inner cavity 211, and the reeling unit 221 is reelably installed with a sealing belt 222, and the end of the sealing belt 222 is fixedly connected to the adjacent motor mounting plate 440. Among them, the reeling unit 221 is a component installed at both ends of the installation inner cavity 211, and its structure is designed to be able to reel and release the sealing belt 222 to adapt to the dynamic position change of the heating unit 300 in the second direction. Specifically, a spring mechanism or a rotating shaft is arranged inside, and the sealing belt 222 is driven by elasticity or torsion to flexibly switch between the reeling state and the unfolding state. When the heating unit 300 moves along the second direction, the reeling unit 221 maintains the appropriate tension of the sealing belt 222 by releasing or reeling the sealing belt 222, ensuring that the sealing performance is not affected during the entire transmission process. The sealing belt 222 is made of a flexible material with certain heat-resistant and wear-resistant properties (such as polytetrafluoroethylene coated cloth, silicone rubber belt or other high-temperature sealing materials), and its width matches the groove wall width of the avoidance slide groove 212; one end of the sealing belt 222 is fixedly connected to the winding unit 221, and the other end is fixed to the motor mounting plate 440 through a fastening structure. This double-end positioning method ensures that the sealing belt 222 always maintains stability during operation and will not be excessively loosened or detached due to winding or releasing.

[0062] Specifically, a support block 450 is installed at the end of the motor mounting plate 440, and the support block 450 is slidably connected to the groove wall of the avoidance chute 212; and the heating unit 300 is at least partially clamped by two support blocks 450. Through the setting of the support block 450, the stability of the heating unit 300 during the stirring process can be further improved.

[0063] On the basis of the above embodiment, the stirring unit 210 includes a first plane 2101, which is respectively arranged parallel to the first direction and the second direction; the heating unit 300 includes a second plane 3001, which is parallel to the first direction and perpendicular to the second direction; wherein the first plane 2101 is the plane with the largest area of ​​the stirring unit 210, and the second plane 3001 is the plane with the largest area of ​​the heating unit 300.

[0064] It can be understood that the first plane 2101, as the largest plane of the stirring unit 210, provides the largest material contact area, thereby ensuring uniform force during the coating stirring process and reducing the uneven temperature distribution caused by insufficient local mixing; the second plane 3001, as the largest plane of the heating unit 300, is arranged parallel to the first direction and perpendicular to the second direction, which helps to evenly diffuse heat from the heating unit 300 to various areas of the stirring chamber 101 and assists in dispersing the aerogel coating.

[0065] Based on the above implementation, Figure 2 and Figure 3As shown, a top stirring assembly 230, a middle stirring assembly 240 and a bottom stirring assembly 250 are sequentially installed on the stirring rod 200 along a first direction, and the top stirring assembly 230, the middle stirring assembly 240 and the bottom stirring assembly 250 each include at least two stirring units 210 distributed at equal intervals; any of the above stirring assemblies is installed with at least two stirring units 210 via a connecting block 260; wherein, a heating unit 300 is installed at the lower end of the stirring unit 210 in the top stirring assembly 230, a heating unit 300 is installed at the upper end and the lower end of the stirring unit 210 in the middle stirring assembly 240, and a heating unit 300 is installed at the upper end of the stirring unit 210 of the bottom stirring assembly 250. Among them, optionally, the first spacing between the top stirring component 230 and the middle stirring component 240 should be smaller than the second spacing between the bottom stirring component 250 and the middle stirring component 240, which means that the two upper heating units 300 are closer in the first direction, and the two lower heating units 300 are farther apart in the first direction. It can be understood that due to the effect of gravity, the heat transfer of the lower heating unit 300 is limited, and too small a spacing can easily lead to heat concentration, affecting the temperature uniformity of the bottom area; and the spacing of the upper heating plates is relatively small, which can ensure that the heat in the upper area can be effectively transferred to the lower layer, thereby ensuring the overall temperature balance in the stirring chamber 101.

[0066] On the basis of the above-mentioned embodiment, the inner heating structure includes a heating wire (not shown) embedded in the stirring rod 200, and the outer heating structure is a heating tube (not shown) arranged around the outside of the stirring shell 100. A heating medium flows through the heating tube, and the heating tube is correspondingly provided with an external circulation structure, such as a pump and a heater, which can adjust the temperature of the heating medium according to the temperature field; the heating unit 300 is an electric heating plate.

[0067] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
