Description

Technical fields:

[0001] This invention relates to the technical field of enameled wire production equipment, and more specifically to a circulating cooling device applied to enameled wire production. Background technology:

[0002] Enamelled wire refers to a metal conductor with an insulating varnish coating used for winding electromagnetic coils; it is also called electromagnetic wire. Currently, the production process of enamelled wire requires baking in an oven. After baking, the surface temperature is high, the varnish film is soft, and the strength is low, requiring online cooling before winding. Currently, online cooling methods for enamelled wire include air cooling and water cooling. Air cooling has a longer cooling cycle, so most manufacturers use water cooling structures. The water cooling structure mainly consists of a long water cooling channel. The enamelled wire is inserted and immersed in the water cooling channel, which contains flowing water that cools the wire. However, because the flowing water gradually heats up, reducing the cooling effect, a longer water cooling channel is needed to meet the cooling requirements. A long water cooling channel occupies a lot of space, so a space-saving water cooling device needs to be designed. Summary of the Invention:

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a circulating cooling device for enameled wire production. The circulating cooling device has multiple vertically distributed cooling channels, and the top of the cooling channels has multiple water outlets with the same water temperature, which can quickly cool down the enameled wire. At the same time, the length of the device is effectively controlled, so it does not occupy a large amount of workshop space.

[0004] A circulating cooling device for enameled wire production includes a cooling tower, a cooling water pump, a water supply pipe, a water return pipe, and a cooling mechanism. The cooling tower is connected to the water supply pipe and the water return pipe. The cooling water pump is installed on the water supply pipe. The cooling mechanism includes a vertical and horizontal trough plate. The upper and lower ends of the trough plate are respectively formed with a horizontal upper baffle and a lower bottom plate. The front end of the lower bottom plate is formed with an inclined water baffle. The two ends of the lower bottom plate are respectively fixed with side baffles.

The upper side of the water guide plate is fixed to the front end face of the trough plate. Cooling slots are formed on the trough plate above the water guide plate and are opposite to the water guide plate and horizontally evenly distributed.

A drain connector is inserted and fixed to the side baffle on the left side of the water receiving trough and connected to the return water pipe.

[0006] Preferably, the upper side of the water guide plate is located behind the lower side of the water guide plate, and the middle and upper parts of the water guide plate are formed with downwardly recessed arc-shaped transverse channels. Several inclined support plates are fixed on the lower end surface of the water guide plate, and the rear end of the support plates is fixed on the groove plate.

[0007] Preferably, the upper side of the baffle plate on the trough plate is located in front of the lower side of the baffle plate and in front of the lower side of the guide plate.

[0021] Example: See Figures 1 to 5 As shown, a circulating cooling device for enameled wire production includes a cooling tower, a cooling water pump, a water supply pipe, a water return pipe, and a cooling mechanism. The cooling tower is connected to the water supply pipe and the water return pipe. The cooling water pump is installed on the water supply pipe. The cooling mechanism includes a vertical and horizontal trough plate 1. The upper and lower ends of the trough plate 1 are respectively formed with a horizontal upper baffle 13 and a lower bottom plate 11. The front end of the lower bottom plate 11 is formed with an inclined baffle plate 12. The two ends of the lower bottom plate 11 are respectively fixed with side baffles 5. The side baffles 5, the lower bottom plate 11, the baffle plate 12, and the trough plate 1 form a water receiving trough. A number of inclined and vertically evenly distributed water guide plates 2 are provided between the water receiving trough and the upper baffle plate 13. The upper side of the water guide plate 2 is fixed to the front end face of the trough plate 1. Cooling slots 14 are formed on the trough plate 1 above the water guide plate 2 and are opposite to the water guide plate 2 and are horizontally evenly distributed.

[0022] The left side of the trough plate 1 is provided with a water inlet assembly 4, which includes several horizontal branch pipes 41. The left end of the branch pipe 41 is formed with a cooling inlet pipe 411 with a longitudinal section of arc shape. The cooling inlet pipe 411 is fixed on the rear end face of the trough plate 1 and connected to the cooling trough opening 14. The right end of the branch pipe 41 is fixedly connected to a vertical main inlet pipe 42. A water inlet connector 43 is fixedly connected to the main inlet pipe 42 and connected to the water supply pipe. The side baffle 5 on the left side of the water receiving trough is inserted and fixedly connected to a drain connector 6, which is connected to the return water pipe.

[0023] The upper side of the water guide plate 2 is located behind the lower side of the water guide plate 2. The middle and upper parts of the water guide plate 2 have downwardly recessed arc-shaped transverse channels 21. Several obliquely placed support plates 20 are fixed on the lower end surface of the water guide plate 2. The rear end of the support plate 20 is fixed on the groove plate 1. The enameled wire set on the water guide plate 2 can fall into the transverse channel 21 of the water guide plate 2, but does not contact the bottom surface of the transverse channel 21. The transverse channel 21 is set to ensure that the water flow on the water guide plate 2 is in full contact with the enameled wire.

[0024] The upper side of the baffle plate 12 on the trough plate 1 is located in front of the lower side of the baffle plate 12 and in front of the lower side of the guide plate 2. The cooling water flowing downward on the guide plate 2 needs to be blocked by the baffle plate 12 before flowing down into the water receiving trough.

[0025] A sealing cover plate 44 is fixedly connected to the right end of the cooling inlet pipe 411 on the water inlet assembly 4. The water inlet pipe 43 is located in the middle of the main inlet pipe 42. Sealing end caps 45 are fixedly connected to the upper and lower ends of the main inlet pipe 42. The left end of the branch pipe 41 abuts against the left end face of the slot plate 1. The left end face of the slot plate 1 can be used to achieve a seal between the left end of the branch pipe 41 and the left end of the cooling inlet pipe 411.

[0026] The length of the water guide plate 2 is less than the length of the trough plate 1. There are gaps between the end faces of the water guide plate 2 and the end faces of the trough plate 1. Although the water flow on the water guide plate 2 mainly flows down along its inclined direction, a small amount of water still flows out from both sides of the water guide plate 2. Therefore, the two ends of the water receiving trough need to be set on both sides of the water guide plate 2.

[0027] The water guide plate 2 has vertical water blowing pipes 9 and air cooling pipes 7 on its left and right sides, respectively. The upper ends of the water blowing pipes 9 and air cooling pipes 7 are respectively inserted and fixed to the upper baffle 13. The side baffle 5 is fixedly connected to a horizontal ventilation pipe 8, and the lower ends of the water blowing pipes 9 and air cooling pipes 7 are respectively inserted and fixed to the ventilation pipe 8. The upper surface of the right end of the upper baffle 13 is fixedly connected to a fan 10 opposite to the air cooling pipe 7. The water blowing pipes 9 and air cooling pipes 7 are respectively formed with a plurality of air blowing pipes that are opposite to the water guide plate 2 and pass through it. The water blowing slot 91 and the air cooling slot 71 on the front outer wall of the water pipe 9 and the air cooling pipe 7 are linearly and evenly distributed on the water blowing pipe 9 and the air cooling pipe 7, respectively. Air is introduced into the air cooling pipe 7 by the fan 10. The air in the air cooling pipe 7 can cool the enameled wire inserted in the air cooling slot 71 and at the same time change the cold air into hot air. The hot air is delivered to the water blowing pipe 9 through the ventilation pipe 8. Then the airflow in the water blowing pipe 9 can blow away the water stains on the enameled wire and realize the drying of the enameled wire.

[0028] The ventilation pipe 8 is located below the water guide plate 2, and both ends of the ventilation pipe 8 are fixedly connected with caps 81.

[0029] Working principle: This invention is a circulating cooling device applied to the production of enameled wire. The carrier of the circulating cooling device is a trough plate 1, and the trough plate 1 is provided with several inclined water guide plates 2. The upper side of each water guide plate 2 is provided with a transverse enameled wire. The enameled wire is moved by the traction of winding. The rear side of the water guide plate 2 is provided with multiple cooling slots 14. The temperature of the coolant output from the cooling slots 14 is the same. Therefore, it can be understood that the cooling water temperature of each section of the enameled wire on the water guide plate 2 is the same, instead of being cooled by the heated coolant. The length of the trough plate 1 does not need to be as long as the existing water cooling channel. Its length can be greatly reduced, and thus the space occupied can be reduced.

[0030] Furthermore, the coolant on the guide plate 2 flows out through the lower end of the guide plate 2 and falls into the water receiving tank. After being cooled by the cooling tower through the return water pipe, it is then transported back to the guide plate 2 to achieve the circulation of coolant.

[0031] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
