Description

Technical Field

[0001] The invention relates to the technical field of enameled wire production, in particular to a cooling device capable of recovering heat energy for enameled wire production. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, then painted and baked several times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Enameled wire needs to be cooled quickly during production and processing. A large amount of heat will be generated during the cooling process of the cooling box and the heat dissipation of the high-temperature enameled wire. If the heat is directly discharged, it will cause a waste of heat energy.

[0003] A Chinese patent with authorization announcement number CN212257022U discloses a cooling device for producing enameled wires. The utility model uses a device body, a water storage tank and a cooling structure in combination. The heat generated by the wire-wrapping device is transferred to an evaporative liquid through the cooling structure, and evaporation occurs. When the evaporative liquid is converted into gas, when the evaporative liquid gas contacts the top of the cooling structure, the evaporative liquid gas is converted back into evaporative liquid. The evaporative liquid flows downward along the inner surface of the cooling structure, and circulates back and forth, so that the heat generated by the wire-wrapping device is transferred to the coolant inside the water storage tank through the cooling structure, so that the temperature of the coolant rises. The coolant can meet part of the needs of the user, thereby achieving the effect of recovering and reusing heat energy.

[0004] However, the device still has some shortcomings: when cooling, the device mainly relies on the automatic heat dissipation of the enameled wire to drive the ethanol in the capillary to volatilize and absorb heat. The active heat dissipation speed of the enameled wire is slow, and the device cannot actively cool the enameled wire, and its actual cooling efficiency is low. In addition, in order to liquefy the gaseous ethanol in the capillary, the temperature difference between the coolant and the ethanol at the top of the capillary needs to be large enough, so the water tank is continuously replenished with low-temperature water. Therefore, when actually cooling, the amount of water replenished by the device is very large, and the temperature of the water pumped out from the water tank actually has little heat storage and is not very useful. At the same time, the device also lacks a structure that actively guides the enameled wire into the wire wrapping device. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the background technology and to provide a cooling device with heat recovery function for enameled wire production.

[0024] Embodiment 1

[0025] like Figure 1-4As shown, a cooling device with heat recovery function for enameled wire production proposed by the present invention includes a box body 1, a cooling box 7, a refrigeration component, a water storage tank 10, a linear module 20 and a movable plate 21.

[0026] An air inlet 2 is provided on one side of the box body 1, and an exhaust hole is provided on the other side. An exhaust fan A4 is provided in the exhaust hole. An exhaust pipe 5 is provided in the side panel where the exhaust fan A4 is located. An exhaust fan B6 is provided in the exhaust pipe 5. A cooling box 7 is provided in the box body 1 and close to the air inlet 2. A plurality of serpentine tubes A71 are provided in the cooling box 7. The serpentine tubes A71 are located below the liquid surface, and the air inlet end of the serpentine tubes A71 is connected to the air inlet 2, and the air outlet end of the serpentine tubes A71 is connected to the interior of the box body 1. A refrigeration component is provided in the cooling box 7. A protection box 8 is provided at the heat dissipation end of the refrigeration component. A connecting pipe 9 connected to the interior of the protection box 8 is provided on the protection box 8.

[0027] The water storage tank 10 is arranged in the box body 1 and near the exhaust hole. The water storage tank 10 is provided with a serpentine pipe B101 and a serpentine pipe C102. The air inlet end of the serpentine pipe B101 is connected to the connecting pipe 9, and the air outlet end of the serpentine pipe B101 is inserted into the exhaust pipe 5 and communicated with the inside thereof. The air inlet end of the serpentine pipe C102 is communicated with the inside of the box body 1, and the air outlet end of the serpentine pipe C102 is inserted into the exhaust hole.

[0028] A plurality of winding wheels 19 are rotatably arranged between the water storage tank 10 and the cooling tank 7. Two threading holes 14 are symmetrically arranged on the box body 1. A sliding cover 15 is slidably arranged in the threading holes 14. A linear module 20 is arranged in the box body 1. The linear module 20 is driven to connect to a movable plate 21. A driving component is arranged in the movable plate 21. A sliding block 24 is slidably arranged on the movable plate 21. The driving component is driven to connect to the sliding block 24. A mechanical claw 25 is arranged on the sliding block 24.

[0029] The specific implementation steps of this embodiment are as follows:

[0030] The first step is to check the liquid level in the cooling box 7 before cooling the enameled wire. If the serpentine tube A71 is not completely immersed below the liquid level, actively add coolant and add an appropriate amount of room temperature or low temperature water to the water storage tank 10 to immerse the serpentine tubes B101 and C102 below the liquid level.

[0031] The second step is to start the refrigeration component to cool the water in the cooling box 7 quickly. At the same time, the exhaust fans A4 and B6 are started to circulate the air in the box 1 and discharge it from the exhaust hole. At this time, the outside air passes through the serpentine pipe A71 in the cooling box 7 and enters the box 1 for replenishment. The air entering the box 1 for replenishment is low-temperature air. At the same time, the air in the protective box 8 circulates at a high speed.

[0032] The fourth step is to insert the high-temperature enameled wire end into the corresponding threading hole 14 and clamp it with the mechanical claw 25, then start the drive component to drive it to descend at a uniform speed to the bottom of the winding wheel 19 at the rightmost lower part, start the linear module 20 to move it horizontally to the left, complete the winding action of the first winding wheel 19, and then use the linear module 20 and cooperate with the drive component to make the enameled wire end pass through each winding wheel 19 in turn and finally pass it out from the left threading hole 14, pull the enameled wire end to wind it around the winch and start automatic winding.

[0033] Step 5: During the winding process of the enameled wire, low-temperature air continuously enters the box 1 to cool it down by blowing. The low-temperature air exchanges heat with the high-temperature enameled wire, and the high-temperature air enters the water tank 10 along the serpentine pipe B101. The water in the water tank 10 absorbs heat and heats up, and can be used as daily warm water supply. At the same time, when the refrigeration component is refrigerating, the high-temperature air generated by the hot end of the refrigeration component also enters the water tank 10, fully recovering the heat generated by the device during operation.

[0034] Embodiment 2

[0035] like Figure 3 As shown, the present invention proposes a cooling device with heat recovery for enameled wire production. Compared with the first embodiment, the refrigeration assembly includes a cold plate 72, a refrigeration sheet 73 and a heat sink fin 75. The cold plate 72 is arranged on the bottom plate of the cooling box 7, the cold end of the refrigeration sheet 73 is in contact with the inner wall of the cold plate 72, the hot end of the refrigeration sheet 73 is connected to a heat conducting rod 74, the lower end of the heat conducting rod 74 passes through the cooling box 7 and the box body 1 and is inserted into the protective box 8, one end of the heat conducting rod 74 inserted into the protective box 8 is connected to the heat sink fin 75, and a plurality of through holes are arranged on the protective box 8.

[0036] In this embodiment, there are multiple ways of cooling, resulting in multiple ways of combining refrigeration components. In this embodiment, the refrigeration plate 73 is selected for cooling, which is very efficient. However, when the refrigeration plate 73 is cooling, a large amount of heat is generated at the hot end. The heat is transferred to the heat dissipation fins 75 through the heat conduction rod 74, and the heat dissipation fins 75 generate high temperature. At this time, the exhaust fan B6 is used to guide the air, and the low-temperature air from the outside enters the protective box 8 to exchange heat with the heat dissipation fins 75, and the hot air enters the water storage tank 10 along the connecting pipe 9, effectively recovering the heat generated by the refrigeration plate 73 during operation.

[0037] Embodiment 3

[0038] like Figure 1-3As shown, the present invention proposes a cooling device with heat recovery for enameled wire production. Compared with the first embodiment, a hot water pipe 11 connected to the interior of the water tank 10 is arranged at the bottom thereof, a valve A is arranged in the hot water pipe 11, a cold water pipe 12 connected to the interior of the water tank 10 is arranged at the top thereof, the cold water pipe 12 is connected to an external water supply pipeline, and a valve B is arranged in the cold water pipe 12.

[0039] In this embodiment, when the hot water in the water tank 10 is heated to a certain temperature, it can be discharged into an external hot water storage tank through the hot water pipe 11 for storage, thereby increasing the hot water supply. At the same time, the water in the external cold water pipe enters the water tank 10 for replenishment, which will not affect heat recovery.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
