Description

Technical Field

[0001] This invention relates to the field of transformer processing, and in particular to a coating impregnation device for transformer processing. Background Technology

[0002] A small transformer impregnation device is an auxiliary device used in the transformer production process to impregnate transformer components with paint in order to enhance their corrosion resistance and extend their service life. It is widely used in the transformer manufacturing industry.

[0003] In existing varnishing devices, when varnishing small transformer components, the small transformers piled together in close contact cannot be completely varnished. This affects the corrosion resistance and service life of the small transformers. In addition, the varnish adhering to the surface of the product after varnishing is easy to stick to the inside of the equipment during transportation, causing damage to the varnish on the product surface and thus affecting its quality. Summary of the Invention

[0004] The purpose of this invention is to provide a coating impregnation device for transformer processing.

[0005] The technical problem of this invention is mainly solved by the following technical solution: A coating impregnation device for transformer processing includes a housing: The box is divided into an upper impregnation chamber and a lower paint storage chamber by a grid. The grid is equipped with a one-way water outlet pipe and a one-way water inlet pipe. The liquid in the impregnation chamber enters the paint storage chamber through the open one-way water outlet pipe. The paint storage chamber is equipped with an air bladder layer.

Detailed Implementation

[0014] The following examples, in conjunction with the appendix, illustrate the concepts. Figure 1-2 The technical solution of the present invention will be further described in detail below.

[0015] A coating impregnation device for transformer processing includes a housing 1: The box 1 is divided into an upper impregnation chamber 3 and a lower paint storage chamber 4 by a grid 2. The grid 2 is equipped with a one-way water outlet pipe 5 and a one-way water inlet pipe 6. The liquid in the impregnation chamber 3 enters the paint storage chamber 4 through the open one-way water outlet pipe 5. The paint storage chamber 4 is equipped with an air bladder layer 7. After the air bladder layer 7 is inflated, the liquid in the paint storage chamber 4 can enter the impregnation chamber 3 through the open one-way water inlet pipe 6. A basket 8 for loading and unloading transformers is suspended inside the impregnation chamber 3. A U-shaped plate 9 is installed at the top of the opening of the basket 8. The side wall of the U-shaped plate 9 is a mesh structure. A drive shaft 10 is installed on the basket 8 inside the opening of the U-shaped plate 9, penetrating the side wall of the box 1. The drive shaft 10 is driven by a motor. Fan blades 11 are installed on the drive shaft 10 inside the opening of the U-shaped plate 9. Air inlet pipes 12 are installed on both sides of the bottom inside the basket 8. One-way air outlet pipes 13 are evenly arranged on the side wall of the air inlet pipes 12. The air inlet pipes 12 are connected to the three-way pipes 15 through pipes 14. The three-way pipes 15 are connected to the hot air blower through corrugated hoses 16. In this embodiment, the air inlet pipe 12 is connected to the discharge end of the three-way pipe 15 through the pipe 14. The discharge end of the three-way pipe 15 is equipped with a solenoid valve. The corrugated hose 16 is connected to the hot air blower through the connecting pipe 17. The airbag layer 7 is connected to the connecting pipe 17 through the recovery pipe 18. The recovery pipe 18 is equipped with a check valve. The connecting pipe 17 is equipped with a heating pipe. A cable 19 connected to a winch 20 is also provided on one side of the bottom of the basket 8. The winch 20 is erected directly above the middle of the top of the basket 8. A feed inlet 21 and a discharge outlet 22 are provided on the side wall of the paint impregnation chamber 3, opposite to the position of the cable 19. The feed inlet 21 is located above the discharge outlet 22. A guide plate 23 is inclined upward on the inner wall of the box 1 at the bottom of the discharge outlet 22. The side wall of the guide plate 23 is a mesh structure. A guide hopper 24 on the same side as the guide plate 23 is also provided on one side of the top of the basket 8.

[0016] In this embodiment, an inlet pipe communicating with the paint impregnation chamber 3 and an outlet pipe communicating with the paint storage chamber 4 are respectively provided at the upper and lower ends of the side wall of the box 1.

[0017] like Figure 1 As shown, a material guiding channel 25 is formed between the U-shaped plate 9 and the corresponding side wall of the box 1. The upper half of the side wall of the U-shaped plate 9 is a solid structure. A sealing plate 26 is provided at the top opening of the U-shaped plate 9. The drive shaft 10 is located at the center of the upper half of the basket 8. Bearings for fixing the drive shaft 10 are provided on both the side wall of the basket 8 and the box 1.

[0018] In this embodiment, a guide roller 27 is provided on the corner edge of the top side of the basket 8 to support the cable 19 and make it bend. The guide roller 27 is provided with limiting blocks at both ends to limit the cable 19.

[0019] Both sides of the bottom of the basket 8 are provided with inclined plates 28, and the two sets of inclined plates 28 form an inverted V-shaped structure. The bottom of the inclined plate 28 is provided with a rotating shaft 29 embedded in the corresponding inner wall of the basket 8. The bottom of the inclined plate 28 above the rotating shaft 29 is provided with a spring 30 that is connected to the corresponding inner wall of the basket 8.

[0020] Working principle: The winch 20 winds the cable 19 to pull the bottom left end of the basket 8, causing the basket 8 to rotate clockwise around the drive shaft 10. This causes the basket 8 to tilt, and its top guide hopper 24 is located below the feed inlet 21. At this time, the feed inlet 21 is opened, and the product can be placed into the basket 8 below the U-shaped plate 9 through the guide channel 25. Then, the winch 20 drives the cable 19 wound by it to unwind. Under the action of the weight of the product inside the basket 8, it rotates counterclockwise and returns to its original position. At this time, the cable 19 is in a slack state to prevent it from pulling the basket 8 and affecting the subsequent swing of the basket 8. In this process, paint is injected into the impregnation chamber 3 to impregnate the products inside the basket 8. During this process, the motor drives the fan blades 11 via the drive shaft 10 to agitate the paint in the impregnation chamber 3, ensuring the paint fully contacts the products inside the basket 8 to improve impregnation efficiency and effectiveness. The U-shaped plate 9 prevents the products from colliding with the rotating fan blades 11 and being damaged due to liquid fluctuations. Simultaneously, a hot air blower directs hot air through the connecting pipe 17, corrugated hose 16, tee pipe 15, and pipe 14 into the air inlet pipe 12, which is then sprayed out through several one-way air outlet pipes 13. This pneumatic agitation of the liquid in the impregnation chamber 3 further enhances the impregnation efficiency and effectiveness by ensuring the paint fully contacts the products inside the basket 8. The hot air also heats the paint. To ensure the good flow properties of the insulating varnish and avoid problems such as incomplete curing or bubbling, the impregnation effect of the product is indirectly improved. At the same time, the gas flow can be controlled by the solenoid valve on the three-way pipe 15 to a certain air inlet pipe 12 and discharged from the corresponding one-way air outlet pipe 13. When the sprayed gas flows to the inclined plate 28, the gas will generate a backward thrust under the influence of its obstruction, thereby driving the basket 8 to rotate around the drive shaft 10. This achieves the purpose of oscillating the basket 8 around the drive shaft 10 by discharging the gas through any air inlet pipe 12 and the corresponding one-way air outlet pipe 13, thereby shaking the product in the basket 8 to switch the different end faces of the product to contact the varnish, thereby improving the impregnation efficiency and effect of the product. After the paint impregnation is completed, the one-way water outlet pipe 5 is opened to allow the paint in the impregnation chamber 3 to enter the paint storage chamber 4, causing the paint on the basket 8 to be drained. At this time, the drive shaft 10 rotates the fan 11 to generate strong airflow to accelerate the air circulation in the basket 8, thereby improving the drying efficiency of the paint. At the same time, the hot airflow discharged from the air inlet pipe 12 and the one-way air outlet pipe 13 can dry the product, effectively preventing damage to the surface paint caused by contact parts during subsequent transportation. After drying, specifically as follows... Figure 2 As shown, the winch 20 winds the cable 19 to pull the bottom left end of the basket 8, causing the basket 8 to rotate clockwise around the drive shaft 10. This tilts the basket 8, and its top guide hopper 24 is positioned directly above the guide plate 23. This tilt allows the product inside to flow along the guide channel 25 onto the guide plate 23. Then, the outlet 22 is opened to remove the product. After the basket 8 is loaded with the product and reset, gas can be injected into the airbag layer 7 to expand it, thereby pushing the paint in the paint storage chamber 4. The liquid flows back to the impregnation chamber 3 through the opened one-way water outlet pipe 6 to impregnate the product. When the liquid in the impregnation chamber 3 enters the paint storage chamber 4, it will compress the air bladder layer 7. At this time, the solenoid valve on the recovery pipe 18 is opened. Then, the gas inside the air bladder layer 7 in the paint storage chamber 4 will enter the connecting pipe 17 through the recovery pipe 18 and be heated by the heating pipe. Finally, it enters the basket 8 through the corrugated hose 16, pipe 14, air inlet pipe 12 and one-way air outlet pipe 13 to dry the product, so as to realize the purpose of recycling the gas inside the air bladder.

[0021] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
