Description

Technical Field

[0001] This utility model relates to the technical field of insulating coating treatment equipment, and in particular to an insulating coating vacuum degassing constant temperature stirring system. Background Technology

[0002] Insulating coatings are widely used in electrical equipment, electronic components, household appliances, and other fields requiring insulation protection. With technological advancements and increasing industrial demands, the performance requirements for insulating coatings are gradually rising, particularly regarding air bubbles and stability. Air bubbles in the coating can lead to uneven coating, thus affecting insulation performance and the coating's lifespan. Therefore, eliminating air bubbles in the coating is a crucial step in the production process.

[0003] In practice, existing coating mixing and degassing methods mostly involve conventional mixing plus manual degassing or simple mechanical mixing. However, these methods have certain limitations. Manual mixing is time-consuming and labor-intensive. Due to manual mixing, the mixing equipment cannot be kept in a vacuum environment, resulting in low degassing efficiency and causing many inconveniences.

[0004] Therefore, this utility model provides a vacuum degassing and constant temperature stirring system for insulating coatings. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vacuum degassing and constant-temperature stirring system for insulating coatings, including a supporting base plate.

[0007] A load-bearing plate is installed on the top of the supporting base plate, a paint treatment tank is installed on the top of the load-bearing plate, a sealing sleeve extending into the load-bearing plate is installed at the bottom of the paint treatment tank, a sealing top cover is installed on the top of the paint treatment tank, a paint treatment chamber and a vacuum degassing machine are installed inside the paint treatment tank, the vacuum degassing machine is located above the paint treatment chamber, and two discharge pipes are installed at the bottom of the paint treatment tank, one of which has a pressure relief valve installed on one side.

[0008] The vacuum degassing machine has a fixed internal limit frame, and a vacuum chamber is fixedly connected to the top of the limit frame. Two vacuum feed pipes are installed on the top of the vacuum chamber, and a vacuum conveying pipe that penetrates the limit frame is installed at the bottom of the vacuum chamber. A vacuum pump is installed inside the vacuum degassing machine and below the vacuum conveying pipe, and the output end of the vacuum pump is connected to the vacuum conveying pipe.

[0009] The coating treatment chamber contains a sedimentation chamber, and a stirring rod is rotatably connected inside the sedimentation chamber. Equally spaced heating and stirring blades are installed on the outside of the stirring rod. The insulating coating entering the coating treatment chamber is subjected to constant-temperature stirring treatment by the rotation of the stirring rod and the heating and stirring blades. The coating treatment chamber also contains a material guide pipe, one end of which extends into the vacuum chamber.

[0010] In a preferred embodiment, a drive motor is installed between the supporting base plate and the load-bearing plate. The bottom of the drive motor is fixedly connected to the supporting base plate. A supporting cross plate is installed on the outside of the output end of the drive motor. The top of the supporting cross plate is fixedly connected to the load-bearing plate. The output end of the drive motor extends into the sealing sleeve and is fixedly connected to one bottom end of the stirring rod. A sealing ring is installed between the sedimentation chamber and the coating treatment chamber. The sealing ring is used to provide auxiliary sealing treatment inside the coating treatment chamber. A third valve is fixedly connected to the outside of the material guiding pipe. A second valve is fixedly connected to the outside of the pressure relief valve. A first valve is fixedly connected to the outside of the discharge pipe. The third valve is used to control the start and stop of the material guiding pipe, facilitating the delivery of the insulating coating that has undergone vacuum degassing treatment to the coating treatment chamber for subsequent operations. The first valve is used to control the start and stop of the discharge pipe, outputting the insulating coating that has undergone constant temperature treatment inside the coating treatment chamber through the discharge pipe. The pressure relief valve is used for auxiliary discharge operations when there is too much coating inside.

[0011] In a preferred embodiment, the supporting base plate is fitted with reinforcing sleeves on all four sides. Support feet are installed at the bottom of each of the four reinforcing sleeves. A bottom connecting plate is installed on the bottom of each reinforcing sleeve and on one side of each support foot. A caster wheel is fixedly connected to the bottom of each bottom connecting plate. The caster wheel drives the entire device to move to different work locations. First positioning bolts extending into the supporting base plate are threaded around the bottom of each bottom connecting plate. Limiting pins that cooperate with the corresponding support feet are installed on the top of each reinforcing sleeve. The connection between the limiting pins and the support feet can be adjusted as needed to facilitate switching between movement and support modes for the entire device, thereby improving the flexibility of the device.

[0012] In a preferred embodiment, a positioning plate is installed on the top of the load-bearing plate, the sealing sleeve penetrates the interior of the positioning plate, a feed valve is installed on the top of the sealing top cover, and inspection ports are provided on both sides of the feed valve. Limiting rods are fixedly connected to the top of the load-bearing plate and around the paint treatment tank. The four limiting rods are used to limit the paint treatment tank around its perimeter. The feed valve is used to assist in the feeding process. When the feed valve and sealing cover are opened, the insulating paint is transported to the vacuum chamber for vacuum degassing through an externally installed pipeline.

The drive motor, feed valve, wireless transceiver, first valve, pressure relief valve, second valve, vacuum degasser, vacuum pump, third valve, and heating and stirring blades are all electrically connected to the control chip. The control chip is used to control the operation of the drive motor, feed valve, wireless transceiver, first valve, pressure relief valve, second valve, vacuum degasser, vacuum pump, third valve, and heating and stirring blades, thereby realizing unified management of electrical equipment.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a supporting base plate, load-bearing plate, coating treatment tank, and vacuum degassing machine, the insulating coating entering the coating treatment chamber is subjected to constant-temperature stirring treatment by rotating stirring rods and heated stirring blades. Four limit stops are used to limit the coating treatment tank from all sides. The feed valve is used to assist in the feeding process. When the feed valve and sealing cover are opened, the insulating coating is transported to the vacuum chamber for vacuum degassing treatment through an externally installed pipeline. The third valve is used to control the start and stop of the guide pipeline. The installation height of the guide pipeline can be adjusted according to actual needs to ensure normal discharge of coating and facilitate the control of the transport of the vacuum-degassed insulating coating to the coating treatment chamber for subsequent operations. The vacuum degassing machine first uses a vacuum pump to remove air from the vacuum chamber, creating a negative pressure environment. While bubbles normally float on the liquid surface, in a vacuum environment, due to the significantly reduced external pressure, the bubbles expand and rise. Under low pressure, the buoyancy of the bubbles is stronger, helping them to quickly escape from the liquid. A sealing ring is used to provide auxiliary sealing inside the coating treatment chamber. Casters are used to move the entire device to different work locations. The connection between the limit pins and support feet can be adjusted as needed, facilitating switching between movement and support modes, thus improving the equipment's flexibility.

[0038] Working principle:

[0039] like Figures 1-6 As shown:

[0040] By setting up a supporting base plate 1, a load-bearing plate 2, a paint treatment tank 3, and a vacuum degassing machine 4, when in use, the vacuum degassing machine 4 first uses a vacuum pump 41 to remove the air inside the vacuum chamber 45, creating a negative pressure environment. Under normal conditions, bubbles float on the surface of the liquid, but under vacuum conditions, due to the greatly reduced external pressure, the volume of the bubbles expands and floats upward. Under low pressure conditions, the buoyancy of the bubbles is stronger, which helps the bubbles to be quickly discharged from the liquid.

[0041] The drive motor 22 drives the stirring rod 51 to rotate. The rotation of the stirring rod 51 and the heating stirring blade 52 performs constant temperature stirring treatment on the insulating coating that enters the coating treatment chamber 5. Four limit bars 23 are used to limit the coating treatment tank 3 around its perimeter. A sealing sleeve 24 is provided on the outside of the stirring rod 51 and at the bottom of the coating treatment tank 3 to prevent liquid leakage during stirring.

[0042] The feed valve 32 is used to assist in the feeding process. When the feed valve 32 and the sealing cover 48 are opened, the insulating coating is transported to the vacuum chamber 45 through the external installation pipe for vacuum degassing treatment. The third valve 44 is used to control the start and stop of the guide pipe 43. The installation height of the guide pipe 43 can be adjusted according to actual needs to ensure that the coating can be discharged normally and to facilitate the control of the conveying of the insulating coating that has completed vacuum degassing treatment to the coating processing chamber 5 for subsequent operations.

[0043] The first valve 37 is used to control the start and stop of the discharge pipe 36, through which the insulating coating that has been constant temperature treated inside the coating processing chamber 5 is output. The pressure relief valve 38 is used to assist in the discharge operation when there is too much coating inside.

[0044] The control chip is used to control the operation of drive motor 22, feed valve 32, wireless signal transceiver 34, first valve 37, pressure relief valve 38, second valve 39, vacuum degassing machine 4, vacuum pump 41, third valve 44 and heating stirring blade 52, realizing unified management of electrical equipment.

[0045] The heating stirring blade 52 has a heating plate inside. The heating plate controls the temperature change through a control chip to ensure that the constant temperature requirement is met. It can also be used for subsequent heating treatment, which improves the flexibility of use.

[0046] The sealing ring 35 is used to provide auxiliary sealing for the inside of the paint treatment chamber 5. The casters 15 are used to drive the entire equipment to move to different work locations. The connection between the limit pin 16 and the support foot 12 can be adjusted as needed to facilitate the switching between moving and supporting modes of the entire equipment, thereby improving the flexibility of the equipment.
