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: 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.

[0006] 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.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0036] The embodiment of the present application discloses a vortex mixing and stirring device for insulating paint. It should be noted that the vortex mixing and stirring device for insulating paint of the present application is mainly used in the stirring and mixing process of insulating paint. In terms of technical effect, it can vortex-stir the solvent and raw materials to enable them to perform convection motion, 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. In addition, in the process of discharging the solvent and raw materials into the mixing kettle 1, a variety of raw materials can be put into the mixing kettle 1 in sequence during the solvent stirring process, which can not only accelerate the rapid mixing between the raw materials and the solvent, but also avoid the adverse effects of putting multiple raw materials together on the insulating paint. Furthermore, the vortex mixing and stirring device for insulating paint of the present application can also adjust the size of the stirring vortex during the stirring and mixing process to ensure that different raw materials are fully mixed with the solvent during the vortex stirring process of different sizes, further improving the stirring and mixing speed and effect of the solvent and raw materials.

[0037] Embodiment 1: Reference Figure 1As shown, an insulating paint vortex mixing and stirring device comprises a mixing kettle 1, a liquid inlet 11 is provided on the side wall of the mixing kettle 1, a liquid inlet check valve is installed inside the liquid inlet 11, and the liquid inlet check valve can prevent the mixture inside the mixing kettle 1 from overflowing during the stirring process, a plurality of annularly distributed feeding barrels 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 top wall of the mixing kettle 1, and a plurality of annularly distributed stirring barrels 6 for stirring and mixing the solvent and raw materials inside the mixing kettle 1 are evenly installed at the lower end of the driving disk 5.

[0038] Furthermore, in this embodiment, the feed part 2 includes an annular groove opened on the top of the mixing kettle 1, the driving disk 5 rotates against the bottom wall of the annular groove, a positioning ring 21 is provided 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 connected to the inside of the reactor.

[0039] In the specific implementation process, the solvent for preparing the insulating paint is first discharged into the mixing kettle 1 through the liquid inlet 11, and then the various raw materials are sequentially fed into the mixing kettle 1 through multiple feeding barrels 4. During this period, the driving disk 5 rotates and drives the stirring drum 6 to stir and mix the solvent and raw materials in the mixing kettle 1, and the stirring drum 6 can make the mixture in the mixing kettle 1 vortex-shaped under the action of centrifugal force during the stirring process, so as to improve the stirring and mixing uniformity of the mixture; after the mixture is stirred and mixed into the insulating paint, the water pump 3 is started, and the insulating paint in the mixing kettle 1 can be discharged through the water pump 3.

[0040] Reference Figure 2 As shown, in order to facilitate the sufficient mixing of the raw materials and the solvent inside the mixing kettle 1, the driving disk 5 can be used to drive the stirring drum 6 to rotate in this embodiment, so as to achieve the stirring and mixing operation. Specifically, a driving motor 12 is installed at the upper end of the mixing kettle 1 through a motor seat, and 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 drums 6 are installed at the bottom of the mixing kettle 1 through a linkage part 13.

[0041] 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 drum 6 at the bottom thereof to stir and mix the solvent and the raw materials through the driving disk 5. At the same time, the mixing effect of the solvent and the raw materials can be enhanced through the linkage part 13.

[0042] Continue to refer to Figure 2As shown, in order to improve the stirring efficiency of the mixing drum 6 on the mixture inside the mixing kettle 1, a corresponding linkage part 13 is provided in the present embodiment. Specifically, the linkage part 13 includes a circular support plate 131, and a plurality of circular holes corresponding to the position of the mixing drum 6 are evenly opened on the driving disk 5. A circular support plate 131 is installed on the inner wall of the circular hole, and a sealing plate 132 is rotatably installed on the bottom of the circular hole. A connecting pipe 133 is rotatably penetrated on the circular support plate 131 and the sealing plate 132. The connecting pipe 133 is located at the eccentric position of the circular support plate 131 and the sealing plate 132, and the sealing plate 132 can separate the circular hole and the mixture inside the mixing kettle 1 to avoid adverse effects. The upper end of the connecting pipe 133 is connected to the positioning ring 21, and the mixing drum 6 is installed at the bottom of the connecting pipe 133.

[0043] Furthermore, in this embodiment, a plurality of driven gears 135 corresponding to the positions of the connecting tubes 133 are rotatably installed at the upper end of the mixing kettle 1 through a positioning shaft 134, and a driving gear ring 136 meshing with the plurality of driven gears 135 is installed at the upper end of the mixing kettle 1. The positioning shaft 134 and the corresponding connecting tubes 133 are connected via a belt drive.

[0044] In the specific implementation process, when the raw materials are put into the feeding cylinder 4, the raw materials pass through the feeding cylinder 4 and the connecting pipe 133 in sequence and enter the mixing kettle 1. When the solvent and the raw materials are stirred, the driving motor 12 is started, and the output shaft of the driving motor 12 drives the driving disk 5 to rotate, and the driving disk 5 drives the positioning shaft 134, the driven gear 135 and the stirring drum 6 to move synchronously in a circumferential direction, so that the stirring drum 6 revolves and stirs and mixes the solvent and the raw materials in the mixing kettle 1; during this period, the driven gear 135 moves in a circumferential direction while maintaining phase with the driving gear ring 136. For rotation, the driven gear 135 drives the positioning shaft 134, the connecting pipe 133 and the mixing drum 6 to rotate as a whole under the action of the active ring gear 136, so that the mixing drum 6 rotates while revolving, thereby enhancing the stirring intensity of the mixing drum 6 on the solvent and the raw material, and the mixing drum 6 can stir the solvent and the raw material inside the mixing kettle 1 in a vortex manner while revolving, and the vortex stirring can promote the convection movement between the solvent and the raw material, intensify the relative movement, help dissolution and dispersion, and make the solvent and the raw material can be strongly mixed, thereby enhancing the mixing and stirring effect.

[0045] Reference Figure 4 and Figure 5As shown, in order to further improve the mixing speed and mixing effect, in the present embodiment, an annular gear ring 138 is sleeved on the outer wall of the circular support plate 131, and a plurality of auxiliary gears 139 respectively meshing with the annular gear ring 138 are arranged inside the driving disk 5 through the rotation of a linkage shaft, and a plurality of arcuate 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 arcuate rack 140 used in the present embodiment is equal to the diameter of the auxiliary gear 139, that is, the auxiliary gear 139 rotates one circle when it meshes with the arcuate rack 140 once, and the diameter of the auxiliary gear 139 is smaller than the diameter of the annular gear ring 138, so the auxiliary gear 139 rotates one circle to drive the annular gear ring 138 and the circular support plate 131 to rotate slightly.

[0046] In the specific implementation process, the driving disc 5 drives the circular support plate 131, the auxiliary gear 139, the connecting pipe 133 and the mixing drum 6 to move circumferentially as a whole during rotation. During this period, when the auxiliary gear 139 is engaged 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, and the circular support plate 131 drives the connecting pipe 133 and the mixing drum 6 to rotate slightly as a whole (at Figure 5 As shown in the figure, the plurality of circular support plates 131 can be rotated intermittently with a small amplitude, and the rotation directions of the plurality of circular support plates 131 are equal, so that the distance between the plurality of stirring drums 6 can be adjusted, and the distance between the plurality of stirring drums 6 remains consistent during the adjustment process, thereby adjusting the distance between the stirring drum 6 and the axis of the mixing kettle 1, so that the stirring vortexes generated by the stirring drum 6 at different positions have different sizes, so as to ensure that different raw materials are fully mixed with the solvent during the vortex stirring process of different sizes, and further improve the stirring and mixing speed and effect of the solvent and the raw materials.

[0047] It should be noted that in order to ensure that the circular support plate 131 can rotate stably under the action of the annular ring gear 138, the auxiliary gear 139 and the arc rack 140, in this embodiment, there are preferably two circular support plates 131 in each circular hole and they are symmetrically distributed up and down along the belt 137.

[0048] Reference Figure 6As shown, the distance between the connecting tube 133 and the positioning shaft 134 changes during the circumferential movement of the connecting tube 133 driven by the circular support plate 131, thereby causing the belt 137 between the connecting tube 133 and the positioning shaft 134 to fail. Based on this, in this embodiment, the driving disk 5 has a plurality of tensioning groups corresponding to the positions of the connecting tubes 133. Each tensioning group includes two mounting grooves that are opened inside the driving disk 5 and symmetrically distributed along the connecting tube 133. Two connecting plates 141 are symmetrically slidably arranged in the mounting grooves. The connecting plates 141 and the mounting grooves are A supporting spring rod 142 is installed between the inner walls of the groove, a tensioning wheel 143 is rotatably arranged between the two connecting plates 141, and a belt 137 is commonly sleeved between the connecting tube 133, the positioning shaft 134 and the two tensioning wheels 143 corresponding to their positions; in the present embodiment, the supporting spring rod 142 always applies an elastic force to 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 groove when the belt 137 is contracted by an external force.

[0049] During the specific implementation process, when the circular support plate 131 rotates and drives the distance between the connecting tube 133 and the positioning shaft 134 to increase, the belt 137 is stretched, and the two tensioning wheels 143 move closer to each other under the action of the belt 137; conversely, when the distance between the connecting tube 133 and the positioning shaft 134 decreases, the tensioning wheel 143 is reset under the action of the supporting spring rod 142 and pushes the belt 137 outward, thereby avoiding transmission failure between the belt 137 and the connecting tube 133 and the positioning shaft 134, so as to ensure the normal operation of the device.

[0050] Reference Figure 7 and Figure 8 As shown, in order to be able to stir the solvent and raw materials inside the mixing kettle 1 in a vortex manner, in the present embodiment, the mixing drum 6 is connected to the connecting pipe 133, and a plurality of liquid discharge cylinders 61 connected thereto are equidistantly installed on the outer wall of the mixing drum 6 from top to bottom, and a discharge one-way valve 62 is installed at one end of the liquid discharge cylinder 61 away from the mixing drum 6, and the discharge one-way valve 62 can close the liquid discharge cylinder 61 to prevent the mixture in the mixing kettle 1 from penetrating into the liquid discharge cylinder 61. It should be noted that an air pump (not shown in the figure) is installed on the upper end of each of the plurality of feeding cylinders 4, and the output end of the air pump extends to the inside of the feeding cylinder 4, and the air can be sucked into the feeding cylinder 4 by the air pump, and then the feeding cylinder 4 is inflated by the air pump, so that the raw materials in the feeding cylinder 4 are discharged through the liquid discharge cylinder 61.

[0051] Furthermore, in the present embodiment, a plurality of annularly distributed water-deflecting plates 51 are installed at the lower end of the driving disk 5, and the side of the water-deflecting plate 51 close to the rotation direction of the driving disk 5 is inclined toward the side away from the axis of the mixing kettle 1, a plurality of through holes 52 are equidistantly provided on the water-deflecting plate 51 from top to bottom, and a plurality of deflecting teeth 53 staggered with the through holes 52 are installed on the side of the water-deflecting plate 51 close to the rotation direction of the driving disk 5.

[0052] In the specific implementation process, after a variety of raw materials are respectively put into the mixing drum 6 from the feeding drum 4, the air pump is started to inflate the mixing drum 6 so that the raw materials in the mixing drum 6 can be discharged into the solvent in the mixing kettle 1 after passing through the liquid discharge tube 61. During this period, since the mixing drum 6 rotates and revolves, the mixing drum 6 can evenly sprinkle the discharged raw materials in the solvent, accelerate the mixing speed between the raw materials and the solvent, avoid the raw materials floating on the upper end of the solvent and difficult to mix quickly, and avoid the accumulation of raw materials affecting the mixing efficiency.

[0053] At the same time, the driving disk 5 drives the water-diverting plate 51 to rotate circumferentially, so that the water-diverting plate 51 stirs the solvent and raw materials in the mixing kettle 1 in the same direction and forms a vortex, so as to facilitate vortex stirring of the solvent and raw materials, and the water-diverting plate 51 can stir the solvent and raw materials through the through hole 52 and the teeth 53, which can further improve the stirring and mixing effect.

[0054] Reference Figure 2 and Figure 3 As shown, since the insulating paint needs to add a variety of raw materials to the solvent in sequence during the production and preparation process, in this embodiment, the various raw materials can be added to the mixing kettle 1 through a plurality of feeding barrels 4 respectively. Specifically, the feeding part 2 also includes an annular receiving frame 22 rotatably mounted on the inner wall of the positioning ring 21, and the middle part of the annular receiving frame 22 gradually tilts downward, and a connecting block 23 is installed between the lower end of the annular receiving frame 22 and the driving disk 5. A plurality of discharge holes corresponding to the position of the connecting pipe 133 are opened on the inner bottom wall of the annular receiving frame 22, and a conduit 24 is installed between the discharge hole and the connecting pipe 133. The lower end of the conduit 24 is rotatably connected to the connecting pipe 133, and the conduit 24 is an elastic tube that can adaptively expand and contract under the action of external force.

[0055] 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 and the upper end of the annular receiving frame 22 have the same contour, and a brush 26 is installed on the lower end of the fixing plate 25, and the brush 26 is in sliding contact with the upper end of the annular receiving frame 22.

[0056] In the specific implementation process, after the raw materials are put into the feeding barrel 4, the raw materials fall to the upper end of the annular receiving frame 22. During this period, the driving motor 12 drives the driving disk 5 to rotate, and the driving disk 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, and the annular receiving frame 22 and the fixed plate 25 move relative to each other, so that the fixed plate 25 cooperates with the brush 26 to clean the raw materials on the upper end of the annular receiving frame 22 into the discharge hole, so that the raw materials pass through the discharge hole, the conduit 24 and the connecting pipe 133 and enter the mixing drum 6, thereby avoiding the contact of the solvent and the raw materials in the mixing kettle 1 with the outside air during the mixing process, avoiding the dust in the air from entering the mixing kettle 1 to affect the purity of the insulating paint, and ensuring that each raw material is discharged into the mixing kettle 1 from multiple discharge holes, thereby ensuring that each raw material is sprinkled from multiple mixing drums 6, so that the raw materials are evenly sprinkled in the solvent, making it easier to mix the solvent and the raw materials.

[0057] Embodiment 2: Reference Fig. 9 As shown, on the basis of Example 1, in order to ensure the mixing effect when the solvent and raw materials inside the mixing kettle 1 are stirred by vortex mixing, in this embodiment, a rotating ring 15 is rotatably installed on the bottom wall of the mixing kettle 1, and a plurality of pads 16 located below the stirring drum 6 are installed on the upper end of the rotating ring 15, and a rotating plate 17 connected to the bottom of the stirring drum 6 is rotatably installed on the upper end of the pad 16, so that the bottom of the stirring drum 6 can be supported by the rotating plate 17, thereby ensuring the stability of the stirring drum 6 during rotation; a plurality of groups of deflector plates 18 staggered with the stirring drum 6 are installed on the upper end of the rotating ring 15, and the number of deflector plates 18 in each group is multiple and uniformly distributed along the circumferential direction of the axis of the rotating ring 15, and the upper ends of the deflector plates 18 are inclined in the rotation direction away from the rotating plates 17.

[0058] Furthermore, in this embodiment, a cross frame 19 is installed between the plurality of pads 16 , and a plurality of stirring teeth 10 are evenly arranged on the upper end of the cross frame 19 .

[0059] During the specific implementation process, while the driving disc 5 drives the stirring drum 6 to revolve, the stirring drum 6 drives the rotating ring 15 to rotate synchronously through the rotating plate 17. The rotating ring 15 applies a rotational force to the solvent and raw materials in the mixing kettle 1 through the diverter 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 achieve an overall vortex rotation under the action of the diverter plate 51 and the diverter plate 18, so as to facilitate comprehensive stirring and mixing of the solvent and raw materials in the mixing kettle 1; at the same time, the rotating ring 15 drives the cross 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 comprehensive mixing.

[0060] In addition, the present invention also provides an insulating paint vortex mixing and stirring method, comprising the following steps: S1: Raw material input: First, the solvent for preparing insulating paint is input into the mixing kettle 1, and then various raw materials are respectively input into the feeding tube 4, and the various raw materials are made to fall to the upper end of the annular receiving frame 22 in sequence. 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 synchronously in a circumferential direction through the connecting block 23, the annular receiving frame 22, and the connecting pipe 133. There is relative movement between the annular receiving frame 22 and the fixed plate 25, so that the fixed plate 25 cooperates with the brush 26 to clean the raw materials on the upper end of the annular receiving frame 22 into the discharge hole, so that the raw materials pass through the discharge hole, the conduit 24 and the connecting pipe 133 and enter the inside of the mixing drum 6.

[0061] Then, the mixing drum 6 is inflated with air through an air pump, so that the raw materials in the mixing drum 6 are discharged into the solvent in the mixing kettle 1 through the liquid discharge tube 61, thereby accelerating the mixing speed between the raw materials and the solvent.

[0062] S2: vortex stirring of raw materials: the driving motor 12 drives the stirring drum 6 at the bottom thereof through the driving disk 5 to cooperate with the water-dispensing plate 51 to stir and mix the solvent and the raw materials, and the driving disk 5 drives the positioning shaft 134, the driven gear 135 and the stirring drum 6 to move synchronously in a circumferential direction, so that the stirring drum 6 revolves. At the same time, the stirring drum 6 rotates under the action of the driven gear 135, the active gear ring 136 and the connecting pipe 133, thereby enhancing the stirring intensity of the stirring drum 6 on the solvent and the raw materials, and the stirring drum 6 can stir the solvent and the raw materials inside the mixing kettle 1 in a vortex while revolving. The vortex stirring can promote the convection movement between the solvent and the raw materials, intensify their relative movement, help dissolve and disperse, and make the solvent and the raw materials mixed strongly, thereby enhancing the mixing and stirring effect.

[0063] During the rotation of the driving disk 5, the circular support plate 131, the auxiliary gear 139, the connecting pipe 133 and the stirring drum 6 are driven to move circumferentially as a whole. During this period, when the auxiliary gear 139 is engaged 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 ring gear 138, and the circular support plate 131 drives the connecting pipe 133 and the stirring drum 6 to rotate slightly as a whole, so that the distance between the stirring drum 6 and the axis of the mixing kettle 1 can be adjusted, so that the stirring vortex generated by the stirring drum 6 at different positions has different sizes, so as to ensure that different raw materials are fully mixed with the solvent during the vortex stirring process of different sizes, and further improve the stirring and mixing speed and effect of the solvent and raw materials.

[0064] While the driving disk 5 drives the stirring drum 6 to revolve, the stirring drum 6 drives the rotating ring 15 to rotate synchronously through the rotating plate 17. The rotating ring 15 applies a rotational force to the solvent and raw materials in the mixing kettle 1 through the deflector plate 18, so that the solvent and raw materials at the bottom of the mixing kettle 1 rotate and form a vortex. The solvent and raw materials can realize an overall vortex rotation under the action of the deflector plate 51 and the deflector plate 18, so as to facilitate comprehensive stirring and mixing of the solvent and raw materials in the mixing kettle 1.

[0065] S3: Discharging the insulating varnish: After the solvent and raw materials in the mixing kettle 1 are mixed into the insulating varnish, the water pump 3 is started to discharge the insulating varnish in the mixing kettle 1 through the water pump 3 .

[0066] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0067] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
