Description

Technical Field

[0001] The invention relates to the technical field of insulating paint mixing, and in particular to an insulating paint vortex mixing and stirring device and a method thereof. Background Art

[0002] Insulating varnish is a coating applied to electrical equipment and electronic components to provide insulation protection, prevent short circuits, and enhance the durability and reliability of the product. It can not only effectively isolate the conductive parts and reduce the risk of current leakage, but also play a role in corrosion resistance, moisture resistance, and dust resistance. Insulating varnish is made by mixing a variety of ingredients such as base material, flame retardant, curing agent, pigment and filler with solvents. However, in order to ensure that the solvent and various ingredients of the insulating varnish are fully mixed, it is usually necessary to gradually add the various ingredients to the solvent for mixing.

[0003] In the prior art, a large number of insulating paint stirring and mixing and corresponding technologies are also disclosed. For a more accurate comparison, for example, a Chinese patent with publication number CN108159918A discloses an insulating paint raw material preparation stirring equipment for cable production, including a bottom plate, a support plate symmetrically connected to the top of the bottom plate, the tops of the two support plates are connected to a box body, a motor is installed on the top of the box body through a frame body, and two rotating rods are rotatably connected to the frame body, one of the rotating rods is connected to a first stirring blade, and the other rotating rod is connected to a second stirring blade.

[0004] When the above-mentioned prior art is in use, the first stirring blade and the second stirring blade are driven to rotate by the motor to stir the raw materials, during which the raw materials in the box can flow back into the box for repeated stirring.

[0005] However, in the process of stirring the insulating paint using the above-mentioned prior art, there are still the following shortcomings:

[0006] 1. During the preparation process of insulating paint, usually the solvent is first poured into a container, and then various raw materials are poured into the solvent in turn for mixing. However, the above-mentioned prior art cannot sprinkle the various raw materials for preparing insulating paint in the solvent step by step and evenly. Therefore, it is easy to cause the raw materials to float on the top of the solvent, which is not only difficult to mix quickly, but also causes the accumulation of raw materials and affects the mixing efficiency, and is easy to cause adverse effects on the prepared insulating paint.

[0007] 2. Although the above-mentioned prior art can stir the raw materials through the first stirring blade and the second stirring blade, the first stirring blade and the second stirring blade can only achieve self-rotation stirring, so there is a stirring dead angle, and the raw materials in the box cannot be fully stirred, affecting the mixing effect of the raw materials.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the insulating paint mixing methods of the prior art. Summary of the invention

[0009] To solve the above problems, the present invention provides a vortex-type mixing and stirring device for insulating paint, which includes a mixing kettle.

A belt drive is connected between the positioning shaft and the corresponding connecting pipe.

[0014] As a preferred technical solution of the present invention, an annular gear ring is sleeved on the outer wall of the circular support plate. A plurality of auxiliary gears respectively meshing with the annular gear ring are rotatably arranged inside the driving disk through linkage shafts, and a plurality of arc-shaped racks meshing with the auxiliary gears are installed inside the driving disk.

[0015] As a preferred technical solution of the present invention, a plurality of tensioning groups corresponding to the positions of the connecting pipes are arranged inside the driving disk. Each tensioning group includes two installation grooves opened inside the driving disk and symmetrically distributed along the connecting pipe. Two connecting plates are symmetrically slidably arranged up and down inside the installation grooves. A support spring rod is installed between the connecting plate and the inner wall of the installation groove. A tensioning wheel is rotatably arranged between the two connecting plates. A belt is sleeved together between the connecting pipe, the positioning shaft and the two tensioning wheels corresponding to their positions.

[0016] As a preferred technical solution of the present invention, the stirring cylinder is communicated with the connecting pipe. A plurality of liquid outlet cylinders communicated with the stirring cylinder are equidistantly installed on the outer wall of the stirring cylinder from top to bottom. A discharge check valve is installed at the end of the liquid outlet cylinder far away from the stirring cylinder.

[0017] As a preferred technical solution of the present invention, a plurality of water deflecting plates distributed annularly are installed at the lower end of the driving disk, and one side of the water deflecting plate close to the rotation direction of the driving disk is inclined away from the axis of the mixing kettle. A plurality of through holes are equidistantly arranged on the water deflecting plate from top to bottom, and a plurality of teeth that are staggered with the through holes are installed on the side of the water deflecting plate close to the rotation direction of the driving disk.

[0018] As a preferred technical solution of the present invention, the feeding part further includes an annular receiving frame rotatably installed on the inner wall of the positioning ring. The middle part of the annular receiving frame gradually slopes downward. A connecting block is installed between the lower end of the annular receiving frame and the driving disk. A plurality of blanking holes corresponding to the positions of the connecting pipes are arranged on the inner bottom wall of the annular receiving frame, and a conduit is installed between the blanking holes and the connecting pipes.

[0019] As a preferred technical solution of the present invention, a plurality of annularly distributed fixing plates are installed on the inner top wall of the positioning ring. The lower end of the fixing plate has the same contour as the upper end of the annular receiving frame, and a brush is installed at the lower end of the fixing plate. The brush is in sliding contact with the upper end of the annular receiving frame.

[0020] In addition, the present invention also provides a method for vortex mixing and stirring of insulating paint, including the following steps:

[0021] S1: Raw material input: First, the solvent for preparing the insulating paint is put into the mixing kettle, and then a variety of raw materials are respectively put into the mixing kettle through a plurality of feeding cylinders in sequence;

[0022] S2: Vortex stirring of raw materials: The driving disk rotates to drive the mixing cylinder to rotate and stir the solvent and raw materials in the mixing kettle, so that the solvent and raw materials in the mixing kettle are in a vortex shape under the action of centrifugal force;

[0023] S3: Discharge of insulating paint: After the solvent and raw materials in the mixing kettle are mixed into insulating paint, start the water pump, and discharge the insulating paint in the mixing kettle through the water pump.

[0024] In summary, the present application includes the following beneficial technical effects:

[0025] First, by vortex stirring the solvent and raw materials, the present invention can make them perform convective motion, which helps to dissolve and disperse, so that the solvent and raw materials can be strongly mixed. In addition, a variety of raw materials can be sequentially sprinkled into the solvent through the mixing cylinder, avoiding the situation that the raw materials float on the upper end of the solvent and are difficult to mix quickly, thereby enhancing the mixing and stirring effect. Moreover, it can also avoid the situation that a variety of raw materials are put in together, which is likely to cause accumulation and affect the mixing efficiency.

[0026] Second, the present invention drives the mixing drum to move circumferentially through the driving disk to achieve revolution, stirring and mixing the solvent and raw materials inside the mixing kettle. During this period, the driven gear cooperates with the driving ring gear to drive the mixing drum to rotate self - rotatably, thereby enhancing the stirring intensity of the mixing drum on the solvent and raw materials. Moreover, while the mixing drum is revolving, it can stir the solvent and raw materials inside the mixing kettle in a vortex pattern.

[0027] Third, during the process of controlling the rotation of the driving disk, the present invention can make the circular support plate rotate intermittently in a small amplitude through the cooperation among the annular gear ring, the auxiliary gear and the arc - shaped rack. Thus, the distance between multiple mixing drums and the axis of the mixing kettle can be adjusted synchronously, making the sizes of the stirring vortices generated by the mixing drums at different positions different, so as to ensure that different raw materials are fully mixed with the solvent during the vortex - type stirring of different sizes, further improving the stirring and mixing speed and effect of the solvent and raw materials.

[0028] Fourth, the present invention inflates the mixing drum, so that the raw materials in the mixing drum are discharged into the solvent through the liquid discharge cylinder. Moreover, during the self - rotation and revolution of the mixing drum, the discharged raw materials can be evenly scattered in the solvent, accelerating the mixing speed between the raw materials and the solvent and avoiding the accumulation of raw materials from affecting the mixing efficiency. During this period, the driving disk drives the water - deflecting plate to rotate circumferentially, which can stir the solvent and raw materials in the mixing kettle in the same direction and form a vortex, facilitating the vortex - type stirring of the solvent and raw materials and ensuring the stirring and mixing effect.

[0029] Fifth, the present invention drives the annular receiving frame to rotate synchronously through the driving disk, so that the fixed plate cooperates with the brush to sweep the raw materials at the upper end of the annular receiving frame into the feeding holes. This not only avoids the contact between the solvent and raw materials in the mixing kettle and the external air, which is likely to cause dust to enter the mixing kettle and affect the purity of the insulating paint, but also ensures that each raw material is discharged from multiple feeding holes into the mixing drum and scattered, and then the raw materials are evenly scattered in the solvent, making it easier for the solvent and raw materials to be mixed.

Detailed implementation manners

[0041] The following combines with the attached Figures 1-9 The embodiments of the present invention will be described in detail.

[0042] The embodiment of the present application discloses a vortex type mixing and stirring device for insulating paint. It should be noted that the vortex type mixing and stirring device for insulating paint in the present application is mainly applied to the mixing process of insulating paint. In terms of technical effects, it can perform vortex stirring on solvents and raw materials, enabling them to undergo convective motion, which helps with dissolution and dispersion, so that the solvents and raw materials can be strongly mixed, thereby enhancing the mixing and stirring effect. In addition, during the process of discharging solvents and raw materials into the mixing kettle 1, various raw materials can be sequentially put into the mixing kettle 1 during the stirring process of the solvents, which can not only accelerate the rapid mixing between the raw materials and solvents, but also avoid the adverse effects on the insulating paint caused by putting multiple raw materials together. Further, the vortex type mixing and stirring device for insulating paint in the present application can also adjust the size of the stirring vortex during the mixing and stirring process to ensure that different raw materials are fully mixed with the solvents during the vortex stirring process of different sizes, further improving the stirring and mixing speed and effect of the solvents and raw materials.

[0043] Embodiment 1:

[0044] Refer to Figure 1 As shown, a vortex type mixing and stirring device for insulating paint includes a mixing kettle 1. A liquid inlet 11 is provided on the side wall of the mixing kettle 1, and a liquid inlet check valve is installed inside the liquid inlet 11. Through the liquid inlet check valve, it can prevent the mixture inside the mixing kettle 1 from overflowing during the stirring process. A plurality of annularly distributed feeding cylinders 4 are installed on the top of the mixing kettle 1 through a feeding part 2. A water pump 3 is arranged at the bottom of the mixing kettle 1. A driving disk 5 is rotatably installed on the inner top wall of the mixing kettle 1, and a plurality of annularly distributed stirring cylinders 6 for stirring and mixing the solvents and raw materials inside the mixing kettle 1 are evenly installed at the lower end of the driving disk 5.

[0045] Further, in this embodiment, the feeding part 2 includes an annular groove opened on the top of the mixing kettle 1. The driving disk 5 rotates and abuts against the inner bottom wall of the annular groove. A positioning ring 21 is arranged at the upper end of the annular groove. The feeding cylinder 4 is installed at the upper end of the positioning ring 21, and the feeding cylinder 4 is communicated with the inside of the reaction kettle.

[0046] In the specific implementation process, first, the solvent for preparing the insulating paint is discharged into the mixing kettle 1 through the liquid inlet 11. Secondly, various raw materials are respectively put into the mixing kettle 1 through a plurality of feeding cylinders 4 in sequence. During this period, the driving disk 5 rotates to drive the stirring cylinder 6 to stir and mix the solvents and raw materials in the mixing kettle 1, and the stirring cylinder 6 can make the mixture in the mixing kettle 1 form a vortex under the action of centrifugal force during the stirring process, so as to improve the mixing uniformity of the mixture; after the mixture is stirred and mixed into insulating paint, start the water pump 3, and discharge the insulating paint in the mixing kettle 1 through the water pump 3.

[0047] Refer to Figure 2As shown in the figure, in order to facilitate the full mixing of the raw materials and solvents inside the mixing kettle 1, in this embodiment, the driving disk 5 can be used to drive the stirring cylinder 6 to rotate, so as to realize the stirring and mixing operation. Specifically, a driving motor 12 is installed on the upper end of the mixing kettle 1 through a motor base. The output shaft of the driving motor 12 passes through the mixing kettle 1 and is connected to the driving disk 5. A plurality of annularly distributed stirring cylinders 6 are installed at the bottom of the mixing kettle 1 through a linkage part 13.

[0048] In the specific implementation process, after the solvent and various raw materials are put into the mixing kettle 1, the driving motor 12 is started. The driving motor 12 drives the stirring cylinder 6 at its bottom through the driving disk 5 to stir and mix the solvent and raw materials. At the same time, the mixing effect of the solvent and raw materials can be enhanced through the linkage part 13.

[0049] Continue to refer to Figure 2 As shown in the figure, in order to improve the stirring efficiency of the stirring cylinder 6 for the mixture inside the mixing kettle 1, a corresponding linkage part 13 is provided in this embodiment. Specifically, the linkage part 13 includes a circular support plate 131. A plurality of circular holes corresponding to the positions of the stirring cylinders 6 are evenly opened on the driving disk 5. The inner wall of the circular hole is provided with a circular support plate 131, and a sealing plate 132 is rotatably installed at the bottom of the circular hole. A connecting pipe 133 is rotatably penetrated through the circular support plate 131 and the sealing plate 132 together. The connecting pipe 133 is located at the eccentric position between the circular support plate 131 and the sealing plate 132, and the sealing plate 132 can separate the circular hole from the mixture inside the mixing kettle 1 to avoid adverse effects. The upper end of the connecting pipe 133 is communicated with the positioning ring 21, and the stirring cylinder 6 is installed at the bottom of the connecting pipe 133.

[0050] Furthermore, in this embodiment, a plurality of driven gears 135 corresponding to the positions of the connecting pipes 133 are rotatably installed at the upper end of the mixing kettle 1 through positioning shafts 134. A driving gear ring 136 meshing with all the driven gears 135 is installed at the upper end of the mixing kettle 1. The positioning shaft 134 and the corresponding connecting pipe 133 are connected by a belt drive.

[0051] In the specific implementation process, when the raw materials are put into the feeding cylinder 4, the raw materials enter the interior of the mixing kettle 1 successively through the feeding cylinder 4 and the connecting pipe 133. When stirring the solvent and the raw materials, the driving motor 12 is started. The output shaft of the driving motor 12 drives the driving disk 5 to rotate. The driving disk 5 drives the positioning shaft 134, the driven gear 135 and the stirring cylinder 6 to move synchronously in the circumferential direction, so that the stirring cylinder 6 performs a revolution and stirs and mixes the solvent and the raw materials inside the mixing kettle 1. During this period, while the driven gear 135 moves in the circumferential direction, it maintains relative rotation with the driving gear ring 136. Therefore, under the action of the driving gear ring 136, the driven gear 135 drives the positioning shaft 134, the connecting pipe 133 and the stirring cylinder 6 to rotate as a whole, so that the stirring cylinder 6 rotates while revolving, thereby enhancing the stirring intensity of the stirring cylinder 6 on the solvent and the raw materials. Moreover, while the stirring cylinder 6 revolves, it can stir the solvent and the raw materials inside the mixing kettle 1 in a vortex manner. Through the vortex stirring, the convective movement between the solvent and the raw materials can be promoted, making their relative movement intensify, which is helpful for dissolution and dispersion, so that the solvent and the raw materials can be strongly mixed, thereby enhancing the mixing and stirring effect.

[0052] Referring to Figure 4 and Figure 5 As shown, in order to further improve the mixing speed and mixing effect, in this embodiment, an annular gear ring 138 is sleeved on the outer wall of the circular support plate 131. A plurality of auxiliary gears 139 respectively meshing with the annular gear ring 138 are rotatably arranged inside the driving disk 5 through a linkage shaft, and a plurality of arc-shaped racks 140 meshing with the auxiliary gears 139 are installed inside the driving disk 5. It should be noted that the arc length of the arc-shaped rack 140 adopted in this embodiment is equal to the diameter of the auxiliary gear 139, that is, the auxiliary gear 139 rotates one circle when meshing with the arc-shaped rack 140 once, and the diameter of the auxiliary gear 139 is smaller than the diameter of the annular gear ring 138. Therefore, when the auxiliary gear 139 rotates one circle, it can drive the annular gear ring 138 and the circular support plate 131 to rotate slightly.

[0053] In the specific implementation process, when the driving disk 5 rotates, it drives the circular support plate 131, the auxiliary gear 139, the connecting pipe 133 and the stirring cylinder 6 to move synchronously in the circumferential direction. During this period, when the auxiliary gear 139 meshes with the arc-shaped rack 140, it rotates, so that the auxiliary gear 139 drives the circular support plate 131 to rotate through the annular gear ring 138. The circular support plate 131 drives the connecting pipe 133 and the stirring cylinder 6 to rotate slightly as a whole (in Figure 5As shown (in the figure), multiple circular support plates 131 can perform small-amplitude intermittent rotation, and the rotation directions of the multiple circular support plates 131 are the same, so that the distances between the multiple mixing drums 6 can be adjusted, and the distances between the multiple mixing drums 6 always remain consistent during the adjustment process. Furthermore, the distance between the mixing drum 6 and the axis of the mixing kettle 1 is adjusted, so that the sizes of the stirring vortices generated by the mixing drum 6 at different positions are different, ensuring that different raw materials are fully mixed with the solvent during the vortex stirring process of different sizes, and further improving the stirring and mixing speed and effect of the solvent and raw materials.

[0054] It should be noted that, in order to ensure the stable rotation of the circular support plate 131 under the action of the annular gear ring 138, the auxiliary gear 139, and the arc-shaped rack 140, in this embodiment, preferably two circular support plates 131 in each circular hole are symmetrically distributed up and down along the belt 137.

[0055] Refer to Figure 6 As shown, during the circumferential movement of the circular support plate 131 driving the connecting pipe 133, the distance between the connecting pipe 133 and the positioning shaft 134 changes, resulting in the failure of the belt 137 between the connecting pipe 133 and the positioning shaft 134. Based on this, in this embodiment, the driving disk 5 has multiple tensioning groups corresponding to the positions of the connecting pipes 133. Each tensioning group includes two installation slots opened inside the driving disk 5 and symmetrically distributed along the connecting pipe 133. Two connecting plates 141 are slidably arranged symmetrically up and down in the installation slots. A support spring rod 142 is installed between the connecting plate 141 and the inner wall of the installation slot. A tensioning wheel 143 is rotatably arranged between the two connecting plates 141. A belt 137 is sleeved together between the connecting pipe 133, the positioning shaft 134, and the two tensioning wheels 143 corresponding to their positions. In this embodiment, the support spring rod 142 always exerts an elastic force on the connecting plate 141 and the tensioning wheel 143, so that the tensioning wheel 143 tensions the belt 137 under the action of the elastic force, and the tensioning wheel 143 can drive the connecting plate 141 to adaptively displace in the installation slot when the belt 137 is contracted under the action of an external force.

[0056] During the specific implementation process, when the circular support plate 131 rotates and drives the distance between the connecting pipe 133 and the positioning shaft 134 to increase, the belt 137 is stretched by the force. At this time, the two tensioning wheels 143 approach each other under the action of the belt 137. On the contrary, when the distance between the connecting pipe 133 and the positioning shaft 134 decreases, the tensioning wheel 143 is reset under the action of the support spring rod 142 and pushes the belt 137 outward, thus avoiding the transmission failure between the belt 137 and the connecting pipe 133 and the positioning shaft 134, and ensuring the normal operation of the device.

[0057] Refer to Figure 7 and Figure 8As shown, in order to be able to stir the solvent and raw materials inside the mixing kettle 1 in a swirling manner, in this embodiment, the stirring cylinder 6 is communicated with the connecting pipe 133. A plurality of liquid discharging cylinders 61 communicated with the stirring cylinder 6 are equidistantly installed on the outer wall of the stirring cylinder 6 from top to bottom. One end of the liquid discharging cylinder 61 away from the stirring cylinder 6 is provided with a discharging one-way valve 62. The discharging one-way valve 62 can seal the liquid discharging cylinder 61 to prevent the mixture in the mixing kettle 1 from penetrating into the liquid discharging cylinder 61. It should be noted that air pumps (not shown in the figure) are installed at the upper ends of a plurality of feeding cylinders 4. The output ends of the air pumps extend into the feeding cylinders 4. Through the air pumps, the raw materials can be sucked into the feeding cylinders 4 and then the air pumps inflate the feeding cylinders 4, so that the raw materials in the feeding cylinders 4 are discharged through the liquid discharging cylinders 61.

[0058] Furthermore, in this embodiment, a plurality of annularly distributed water deflecting plates 51 are installed at the lower end of the driving disk 5, and one side of the water deflecting plate 51 close to the rotation direction of the driving disk 5 inclines away from the axis of the mixing kettle 1. A plurality of through holes 52 are equidistantly opened on the water deflecting plate 51 from top to bottom, and a plurality of teeth 53 staggered with the through holes 52 are installed on one side of the water deflecting plate 51 close to the rotation direction of the driving disk 5.

[0059] In the specific implementation process, after putting various raw materials into the stirring cylinder 6 from the feeding cylinders 4 respectively, start the air pump. The air pump inflates the stirring cylinder 6 to facilitate discharging the raw materials in the stirring cylinder 6 into the solvent in the mixing kettle 1 through the liquid discharging cylinders 61. During this period, since the stirring cylinder 6 rotates and revolves, the stirring cylinder 6 can evenly sprinkle the discharged raw materials in the solvent, accelerating the mixing speed between the raw materials and the solvent, preventing the raw materials from floating on the upper end of the solvent and being difficult to mix quickly, and avoiding the accumulation of raw materials from affecting the mixing efficiency.

[0060] Meanwhile, the driving disk 5 drives the water deflecting plate 51 to rotate circumferentially, so that the water deflecting plate 51 stirs the solvent and raw materials in the mixing kettle 1 in the same direction to form a vortex, facilitating the swirling stirring of the solvent and raw materials. Moreover, the water deflecting plate 51 can stir the solvent and raw materials through the through holes 52 and the teeth 53, which can further improve the stirring and mixing effect.

[0061] Refer to Figure 2 and Figure 3As shown, since a variety of raw materials need to be added to the solvent in sequence during the production and preparation of insulating paint, in this embodiment, a variety of raw materials can be respectively added into the mixing kettle 1 through multiple feeding cylinders 4. Specifically, the feeding part 2 further includes an annular receiving frame 22 rotatably installed on the inner wall of the positioning ring 21. The middle part of the annular receiving frame 22 gradually slopes downward. A connecting block 23 is installed between the lower end of the annular receiving frame 22 and the driving disc 5. A plurality of material discharging holes corresponding to the positions of the connecting pipes 133 are formed in the inner bottom wall of the annular receiving frame 22. A conduit 24 is installed between the material discharging holes and the connecting pipes 133. The lower end of the conduit 24 is rotatably connected to the connecting pipe 133, and the conduit 24 is an elastic tube capable of self-adaptively expanding and contracting under an external force.

[0062] Furthermore, in this embodiment, a plurality of annularly distributed fixing plates 25 are installed on the inner top wall of the positioning ring 21. The lower end of the fixing plate 25 has the same contour as the upper end of the annular receiving frame 22, and a brush 26 is installed at the lower end of the fixing plate 25. The brush 26 is in sliding contact with the upper end of the annular receiving frame 22.

[0063] In the specific implementation process, after the raw materials are put into the feeding cylinder 4, the raw materials fall onto the upper end of the annular receiving frame 22. During this period, the driving motor 12 drives the driving disc 5 to rotate. The driving disc 5 drives the annular receiving frame 22 to rotate synchronously through the connecting block 23, so that the annular receiving frame 22 and the connecting pipe 133 move synchronously. However, the annular receiving frame 22 and the fixing plate 25 are in relative motion. Thus, the fixing plate 25 and the brush 26 can sweep the raw materials on the upper end of the annular receiving frame 22 into the material discharging holes, so that the raw materials enter the inside of the stirring cylinder 6 after passing through the material discharging holes, the conduits 24 and the connecting pipes 133. Thereby, it is avoided that the solvent and the raw materials in the mixing kettle 1 come into contact with the outside air during the stirring and mixing process, and it is avoided that dust in the air enters the mixing kettle 1 to affect the purity of the insulating paint. Moreover, it can be ensured that each kind of raw material is discharged into the mixing kettle 1 from a plurality of material discharging holes, and further ensured that each kind of raw material is sprinkled out from a plurality of stirring cylinders 6, so that the raw materials are evenly sprinkled in the solvent, making it easier for the solvent and the raw materials to be mixed.

[0064] Embodiment Two:

[0065] Refer to Figure 9As shown, on the basis of the first embodiment, in order to ensure the mixing effect when stirring the solvent and raw materials inside the mixing kettle 1 in a vortex mixing manner, in this embodiment, a rotating ring 15 is rotatably installed on the inner bottom wall of the mixing kettle 1. A plurality of backing plates 16 are installed at the upper end of the rotating ring 15 and are located below the stirring cylinder 6. A rotating plate 17 connected to the bottom of the stirring cylinder 6 is rotatably installed at the upper end of the backing plate 16. The bottom of the stirring cylinder 6 can be supported by the rotating plate 17, thereby ensuring the stability of the stirring cylinder 6 during rotation; a plurality of flow deflecting plates 18 are installed at the upper end of the rotating ring 15 and are staggered with the stirring cylinder 6. The number of each group of flow deflecting plates 18 is multiple and is evenly distributed circumferentially along the axis of the rotating ring 15, and the upper end of the flow deflecting plate 18 is inclined in the rotating direction away from the rotating plate 17.

[0066] Furthermore, in this embodiment, a cross-shaped frame 19 is commonly installed among the plurality of backing plates 16, and a plurality of stirring teeth 10 are evenly arranged at the upper end of the cross-shaped frame 19.

[0067] During the specific implementation process, while the driving disk 5 drives the stirring cylinder 6 to revolve, the stirring cylinder 6 drives the rotating ring 15 to rotate synchronously through the rotating plate 17. The rotating ring 15 applies a rotating force to the solvent and raw materials in the mixing kettle 1 through the flow deflecting plates 18, causing the solvent and raw materials at the bottom of the mixing kettle 1 to rotate and form a vortex. Moreover, under the action of the water deflecting plate 51 and the flow deflecting plates 18, the solvent and raw materials can achieve overall vortex rotation, so as to facilitate the full stirring and mixing of the solvent and raw materials in the mixing kettle 1; meanwhile, the rotating ring 15 drives the cross-shaped frame 19 and the stirring teeth 10 at its upper end to fully stir the solvent and raw materials in the middle of the mixing kettle 1 to ensure full mixing.

[0068] In addition, the present invention also provides a method for vortex mixing and stirring of insulating paint, including the following steps:

[0069] S1: Raw material input: First, the solvent for preparing the insulating paint is put into the mixing kettle 1. Secondly, various raw materials are respectively put into the feeding cylinder 4, and the various raw materials are successively dropped onto the upper end of the annular receiving rack 22. During this period, the driving motor 12 is started, and the driving motor 12 drives the driving disk 5 to rotate. The driving disk 5 moves circumferentially synchronously through the connecting block 23, the annular receiving rack 22, and the connecting pipe 133. There is relative movement between the annular receiving rack 22 and the fixed plate 25. Thus, the fixed plate 25 cooperates with the brush 26 to sweep the raw materials on the upper end of the annular receiving rack 22 into the feeding hole, so that the raw materials enter the inside of the stirring cylinder 6 after passing through the feeding hole, the conduit 24, and the connecting pipe 133.

[0070] Subsequently, air is filled into the stirring cylinder 6 through an air pump, so as to discharge the raw materials in the stirring cylinder 6 into the solvent in the mixing kettle 1 through the liquid outlet cylinder 61, and accelerate the mixing speed between the raw materials and the solvent.

[0071] S2: Vortex stirring of raw materials: The driving motor 12 drives the stirring cylinder 6 at its bottom through the driving disk 5, and cooperates with the water deflecting plate 51 to stir and mix the solvent and raw materials. The driving disk 5 drives the positioning shaft 134, the driven gear 135 and the stirring cylinder 6 to move circumferentially synchronously, so that the stirring cylinder 6 makes a revolution. At the same time, the stirring cylinder 6 rotates self - rotatively under the action of the driven gear 135, the driving ring gear 136 and the connecting pipe 133, thereby enhancing the stirring intensity of the stirring cylinder 6 on the solvent and raw materials. And when the stirring cylinder 6 makes a revolution, it can stir the solvent and raw materials inside the mixing kettle 1 in a vortex manner. Through the vortex stirring, the convective movement between the solvent and raw materials can be promoted, making their relative movement more intense, which is helpful for dissolution and dispersion, so that the solvent and raw materials can be strongly mixed, thereby enhancing the mixing and stirring effect.

[0072] During the rotation of the driving disk 5, it drives the circular support plate 131, the auxiliary gear 139, the connecting pipe 133 and the stirring cylinder 6 to move circumferentially as a whole. During this period, when the auxiliary gear 139 meshes with the arc rack 140, it rotates, so that the auxiliary gear 139 drives the circular support plate 131 to rotate through the annular gear ring 138. The circular support plate 131 drives the connecting pipe 133 and the stirring cylinder 6 to rotate slightly as a whole, thereby adjusting the distance between the stirring cylinder 6 and the axis of the mixing kettle 1, so that the sizes of the stirring vortices generated by the stirring cylinder 6 at different positions are different, ensuring that different raw materials are fully mixed with the solvent during the vortex stirring of different sizes, and further improving the stirring and mixing speed and effect of the solvent and raw materials.

[0073] While the driving disk 5 drives the stirring cylinder 6 to make a revolution, the stirring cylinder 6 drives the rotating ring 15 to rotate synchronously through the rotating plate 17. The rotating ring 15 applies a rotating force to the solvent and raw materials in the mixing kettle 1 through the flow deflecting plate 18, so that the solvent and raw materials at the bottom of the mixing kettle 1 rotate and form a vortex, and the solvent and raw materials can realize overall vortex rotation under the action of the water deflecting plate 51 and the flow deflecting plate 18, so as to fully stir and mix the solvent and raw materials in the mixing kettle 1.

[0074] S3: Discharge of insulating paint: After the solvent and raw materials in the mixing kettle 1 are mixed into insulating paint, start the water pump 3, and discharge the insulating paint in the mixing kettle 1 through the water pump 3.

[0075] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above - mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0076] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
