Description

Technical Field

[0001] This utility model relates to a closed, heat-insulating, anti-corrosion coating stirring and dispersing device. Background Technology

[0002] In the production and processing of anti-corrosion coatings, stirring and dispersion is one of the core processes. The uniformity of dispersion and viscosity stability of the coating directly determine its subsequent construction effect and anti-corrosion performance. However, existing anti-corrosion coating stirring and dispersion devices lack a complete integrated structure for heat preservation and heating in practical applications. The stirring tank relies on a single insulation layer or local heating components to maintain the temperature, which leads to significant temperature differences between the side walls and bottom, and between the central and edge areas of the tank. Anti-corrosion coatings are highly sensitive to temperature, and local temperature fluctuations can cause abnormal fluctuations in coating viscosity, resulting in coating agglomeration and insufficient dispersion, ultimately affecting the uniformity and flowability of the coating. In view of this, this utility model proposes a closed-type heat-insulated anti-corrosion coating stirring and dispersion device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a closed, heat-insulating, anti-corrosion coating stirring and dispersing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A closed-type heat-insulating anti-corrosion coating mixing and dispersing device includes a mixing tank, and a rotatable stirring rod is provided inside the mixing tank; The outer wall of the mixing tank is provided with a heat-insulating shell, and a heat-insulating cavity and a heating cavity are provided between the heat-insulating shell and the mixing tank. The heat-insulating cavity and the heating cavity are connected. The heat-insulating cavity is located at the side wall of the mixing tank, and the heating cavity is located at the bottom of the mixing tank. The heating cavity is equipped with a disturbance component, and the insulation cavity is equipped with a flowing insulation liquid. The flowing insulation liquid comes into contact with the disturbance component, thereby accelerating the exchange of insulation fluid between the insulation cavity and the heating cavity.

[0005] As an improvement to the above technical solution, a discharge pipe is provided at the bottom of the mixing tank, the discharge pipe is provided through the insulation shell, and the discharge pipe is provided in the insulation cavity; The disturbance component is installed on the discharge pipe.

[0006] As an improvement to the above technical solution, two sets of limiting circular plates are symmetrically arranged on the outer wall of the discharge pipe; The disturbance component includes a disturbance sleeve, which is rotatably disposed between two sets of limiting circular plates. The outer wall of the disturbance sleeve is provided with disturbance blades, which are in contact with the flowing heat-insulating liquid, so that the disturbance blades and the disturbance sleeve rotate in the heating cavity.

[0007] As an improvement to the above technical solution, a lifting screw is provided in the heat-insulating cavity, and the lifting screw is connected to the inner wall of the heat-insulating shell and the outer wall of the stirring tank. The outer wall of the insulation shell is provided with a liquid inlet pipe and a liquid outlet pipe, which are tangent to the insulation shell, and the liquid inlet pipe is located above the liquid outlet pipe.

[0008] As an improvement to the above technical solution, the heating chamber is further provided with multiple sets of electric heating rods, which are arranged in a ring array around the axis of the discharge pipe. The electric heating rod is connected to the insulation shell.

[0009] As an improvement to the above technical solution, the disturbance sleeve is provided with a rotating annular groove, and multiple sets of the electric heating rods are arranged at the position of the rotating annular groove.

[0010] As an improvement to the above technical solution, the outer wall of the disturbance sleeve is provided with multiple sets of actuating rods, and the multiple sets of actuating rods are arranged in a ring array with the axis of the disturbance sleeve as the center. The disturbance blade is positioned above the electric heating rod, and the actuating lever is positioned below the electric heating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting an insulation shell on the outer wall of the mixing tank and dividing the space between the insulation shell and the mixing tank into a connected insulation cavity and a heating cavity, the insulation liquid can cover the side wall and bottom area of ​​the mixing tank, thereby achieving a surrounding temperature maintenance of the mixing tank. This avoids problems such as viscosity fluctuation and uneven dispersion of the anti-corrosion coating inside the tank due to local temperature differences in the mixing tank, and ensures the temperature stability of the coating during the mixing and dispersion process. By setting up a disturbance component in the heating chamber that comes into contact with the flowing insulation liquid, the disturbance component is driven by the flow of the insulation liquid itself. This creates disturbance in the insulation liquid in the heating chamber without the need for an additional drive mechanism, breaking the flow obstruction between the heating chamber and the insulation chamber, accelerating the circulation and exchange rate of the insulation liquid between the two chambers, ensuring that the heated insulation liquid in the heating chamber can be quickly transferred to the insulation chamber, improving the overall insulation and heating efficiency, and reducing additional power consumption to achieve energy saving. Based on the aforementioned effects of stable temperature and efficient heat exchange, the anti-corrosion coating inside the tank can always be kept in a suitable stirring temperature environment. Combined with the dispersing effect of the rotating stirring rod, it can effectively avoid problems such as coating agglomeration and insufficient dispersion caused by unsuitable temperature, improve the uniformity of stirring and dispersion of the anti-corrosion coating, and thus ensure the performance stability of the coating in subsequent construction and use.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figure 1-9As shown, this embodiment proposes a closed heat-insulating anti-corrosion coating stirring and dispersing device, including a stirring tank 10, wherein a rotatable stirring rod 11 is provided inside the stirring tank 10; The outer wall of the mixing tank 10 is provided with a heat-insulating shell 20. A heat-insulating cavity 23 and a heating cavity 24 are provided between the heat-insulating shell 20 and the mixing tank 10. The heat-insulating cavity 23 and the heating cavity 24 are connected. The heat-insulating cavity 23 is located at the side wall of the mixing tank 10, and the heating cavity 24 is located at the bottom of the mixing tank 10. The heating cavity 24 is provided with a disturbance component 50, and the heat preservation cavity 23 is provided with a flowing heat preservation liquid. The flowing heat preservation liquid comes into contact with the disturbance component 50, thereby accelerating the exchange of heat preservation fluid between the heat preservation cavity 23 and the heating cavity 24.

[0016] In this embodiment, when dispersing and stirring the anti-corrosion coating, a flowing heat-insulating liquid is first introduced into the heat-insulating cavity 23. The heat-insulating liquid drives the disturbance component 50 to operate in the heating cavity 24, disturbing the flowing heat-insulating liquid and accelerating the exchange of heat-insulating fluid between the heat-insulating cavity 23 and the heating cavity 24. By setting an insulation shell 20 on the outer wall of the mixing tank 10 and dividing the space between the insulation shell 20 and the mixing tank 10 into a connected insulation cavity 23 and a heating cavity 24, the insulation liquid can cover the side wall and bottom area of ​​the mixing tank 10, thereby achieving a surrounding temperature maintenance of the mixing tank 10. This avoids problems such as viscosity fluctuation and uneven dispersion of the anti-corrosion coating inside the tank due to local temperature differences in the mixing tank 10, and ensures the temperature stability of the coating during the mixing and dispersion process. By setting a disturbance component 50 in the heating cavity 24 that is in contact with the flowing insulation liquid, the disturbance component 50 is driven by the flow of the insulation liquid itself. Without the need for an additional drive mechanism, the insulation liquid in the heating cavity 24 can be disturbed, breaking the flow obstruction of the insulation liquid between the heating cavity 24 and the insulation cavity 23, accelerating the circulation and exchange rate of the insulation liquid between the two cavities, ensuring that the heated insulation liquid in the heating cavity 24 can be quickly transferred to the insulation cavity 23, improving the overall insulation and heating efficiency, while reducing additional power consumption and achieving energy saving effect. Based on the aforementioned effects of stable temperature and efficient heat exchange, the anti-corrosion coating inside the tank can always be kept in a suitable stirring temperature environment. Combined with the dispersing effect of the rotating stirring rod 11, it can effectively avoid problems such as coating agglomeration and insufficient dispersion caused by unsuitable temperature, improve the uniformity of stirring and dispersion of the anti-corrosion coating, and thus ensure the performance stability of the coating in subsequent construction and use.

[0017] Specifically, the bottom end of the mixing tank 10 is provided with a discharge pipe 12, which penetrates the insulation shell 20 and is located in the insulation cavity 23; The disturbance component 50 is installed on the discharge pipe 12.

[0018] In this embodiment, the discharge pipe 12 passes through the insulation shell 20 and is located in the insulation cavity 23, so that the insulation liquid in the insulation cavity 23 can form a surrounding wrap around the discharge pipe 12, which can effectively reduce the heat exchange between the anti-corrosion coating in the discharge pipe 12 and the external environment, and avoid problems such as increased viscosity, poor fluidity or even agglomeration of the coating due to a sudden drop in temperature during the process of transporting the coating from the mixing tank 10 to the outside. This ensures the temperature consistency of the coating throughout the entire process from mixing and dispersing to discharge, and guarantees the material performance for subsequent construction or storage. By directly mounting the disturbance component 50 on the discharge pipe 12, there is no need to design an additional independent mounting bracket or fixing structure for the disturbance component 50, which greatly simplifies the overall structural layout of the device and reduces the number of parts and assembly processes. At the same time, the discharge pipe 12, as the core load-bearing and conveying component of the mixing tank 10, has high structural strength and good positional stability, which can provide a stable mounting foundation for the disturbance component 50. This effectively avoids problems such as displacement and shaking of the disturbance component 50 during operation with the insulation liquid, improves its operational reliability, and makes full use of the idle space around the discharge pipe 12, thereby improving the utilization efficiency of the internal space of the device.

[0019] Specifically, two sets of limiting circular plates 13 are symmetrically arranged on the outer wall of the discharge pipe 12; The disturbance component 50 includes a disturbance sleeve 51, which is rotatably disposed between two sets of limiting circular plates 13. The outer wall of the disturbance sleeve 51 is provided with disturbance blades 52, which are in contact with the flowing heat-insulating liquid, so that the disturbance blades 52 and the disturbance sleeve 51 rotate in the heating cavity 24.

[0020] In this embodiment, two sets of symmetrically arranged limiting circular plates 13 can axially limit the disturbance sleeve 51 rotatably installed therebetween, effectively restricting the displacement of the disturbance sleeve 51 along the axial direction of the discharge pipe 12, preventing the disturbance sleeve 51 from axially shifting or moving due to liquid impact force, its own inertia, and other factors during the rotation driven by the heat preservation liquid. At the same time, it does not interfere with the circumferential rotational freedom of the disturbance sleeve 51, ensuring that the disturbance sleeve 51 always operates stably within the preset working area of ​​the heating cavity 24, preventing the disturbance blade 52 from failing to effectively contact the heat preservation liquid and the disturbance function from failing due to the misalignment of the disturbance sleeve 51, and significantly improving the operational reliability of the disturbance component 50 and the overall working stability of the device.

[0021] Specifically, a lifting screw 30 is provided in the heat-insulating cavity 23, and the lifting screw 30 is connected to the inner wall of the heat-insulating shell 20 and the outer wall of the stirring tank 10; The outer wall of the heat insulation shell 20 is provided with a liquid inlet pipe 21 and a liquid outlet pipe 22. The liquid inlet pipe 21 and the liquid outlet pipe 22 are tangent to the heat insulation shell 20, and the liquid inlet pipe 21 is located above the liquid outlet pipe 22.

[0022] In this embodiment, the lifting spiral 30 connects the inner wall of the insulation shell 20 and the outer wall of the mixing tank 10, forming a spiral guide channel along the side wall of the mixing tank 10 inside the insulation cavity 23. When the insulation liquid flows in the insulation cavity 23, the lifting spiral 30 can forcefully guide the liquid, preventing the liquid from flowing only along the bottom of the cavity or stagnating in a local area due to gravity. This promotes the insulation liquid to flow circumferentially along the side wall of the mixing tank 10 and fully contact the outer wall of the mixing tank 10, ensuring that all areas of the side wall of the mixing tank 10 are evenly covered by the insulation liquid. This effectively solves the problem of insufficient local insulation and large temperature differences on the side wall of the tank caused by disordered liquid flow in traditional insulation cavities 23, providing a uniform side wall insulation environment for the anti-corrosion coating inside the tank and preventing the coating from having uneven viscosity and reduced dispersion quality due to local temperature fluctuations. The inlet pipe 21 and outlet pipe 22 are tangent to the insulation shell 20, so that when the insulation liquid enters the insulation cavity 23 from the inlet pipe 21, it can form a circumferential rotating flow along the tangential direction of the inner wall of the insulation shell 20. This rotating flow can reduce the impact resistance between the liquid and the shell wall when the liquid enters, and at the same time drive the liquid inside the insulation cavity 23 to form an overall circulation, avoiding the liquid from directly impacting the tank wall and causing local turbulence and uneven distribution. The tangential design of the liquid outlet pipe 22 can be adapted to the direction of the rotating flow formed by the liquid inlet pipe 21, ensuring smooth liquid discharge, reducing the stagnation and loss of liquid flow inside the cavity, further improving the uniformity of the distribution of the insulation liquid in the insulation cavity 23, and laying the foundation for subsequent heat exchange. Of course, when the insulation liquid flows in the insulation cavity 23, the lifting screw 30 can force the liquid to flow and impact the disturbance blade 52, so that the disturbance blade 52 rotates and disturbs in the heating cavity 24 to accelerate fluid exchange. Of course, a pump body is installed between the liquid outlet pipe 22 and the liquid inlet pipe 21. The pump body guides the heat-insulating liquid in the liquid outlet pipe 22 into the liquid inlet pipe 21 to form a circulating fluid heat-insulating liquid.

[0023] Specifically, the heating chamber 24 is also provided with multiple sets of electric heating rods 40, which are arranged in a ring array around the axis of the discharge pipe 12. The electric heating rod 40 is connected to the heat preservation shell 20.

[0024] In this embodiment, multiple sets of electric heating rods 40 are arranged in a ring array around the axis of the discharge pipe 12, which can make the heat inside the heating cavity 24 evenly distributed along the circumference of the discharge pipe 12, effectively avoiding heating blind spots and local overheating problems caused by single or asymmetrical arrangements. The symmetry of the ring array ensures that the heating rate of the insulation liquid in each area of ​​the heating chamber 24 is consistent, which can quickly heat the insulation liquid to the preset temperature and maintain it stably. Then, through the heat conduction between the insulation liquid and the bottom of the mixing tank 10, a uniform and constant temperature environment is provided for the anti-corrosion coating in the tank, preventing the coating from viscosity fluctuation, agglomeration or uneven dispersion due to local temperature differences, and ensuring the quality of coating mixing and dispersion. The heat generated by the electric heating rod 40 can be quickly transferred to the insulating liquid flowing around the discharge pipe 12, and then rapidly diffused to the entire heating chamber 24 and insulating chamber 23 through the disturbance effect of the disturbance component 50 and the liquid circulation, reducing heat loss during the transfer process. Compared with the non-surround arrangement, this structure can make the insulating liquid reach the target temperature faster, significantly improve heating efficiency, reduce the energy consumption of the electric heating rod 40, and achieve efficient energy utilization.

[0025] Specifically, the disturbance sleeve 51 is provided with a rotating annular groove 53, and multiple sets of electric heating rods 40 are arranged at the position of the rotating annular groove 53.

[0026] In this embodiment, the structural design of the rotating annular groove 53 can form a precise spatial fit with the multiple sets of electric heating rods 40 arranged in an annular array, so that the electric heating rods 40 can be embedded in the rotating annular groove 53 without physical interference with the outer wall of the disturbance sleeve 51.

[0027] Specifically, the outer wall of the disturbance sleeve 51 is provided with multiple sets of actuating rods 54, and the multiple sets of actuating rods 54 are arranged in a ring array around the axis of the disturbance sleeve 51; The disturbance blade 52 is positioned above the electric heating rod 40, and the toggle lever 54 is positioned below the electric heating rod 40.

[0028] In this embodiment, multiple sets of actuating rods 54 are arranged in a ring array around the axis of the disturbance sleeve 51, which can form a circumferential disturbance area around the discharge pipe 12 at the lower part of the heating chamber 24, which can agitate the heat-insulating liquid at the bottom of the heating chamber 24 in all directions and effectively break the stagnation state of the liquid at the bottom of the chamber.
