Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, specifically to an energy-saving and environmentally friendly cooling tower for wire drawing machines. Background Technology

[0002] The domestic wire drawing machine market is currently dominated by traditional pulley-type wire drawing machines, supplemented by double-drum, straight-line, looper, tuning roller linear, combined, and various water tank wire drawing machines. Wire drawing machines can be categorized into large continuous tank wire drawing machines, large water tank wire drawing machines, small water tank wire drawing machines, and pulley-type wire drawing machines. The pulley-type wire drawing machine is a non-slip, dry, continuous wire drawing machine capable of wire accumulation. During the drawing process, there is no relative sliding between the wire and the drum surface along the circumference of the drum, resulting in relatively small surface wear. Furthermore, when one drum temporarily stops, the drums following it can continue operating for a period of time based on their respective wire accumulation. This type of machine has advantages such as simple structure, convenient operation and maintenance, and low manufacturing cost.

[0003] During the wire drawing process, cooling towers are often used for auxiliary cooling. A typical cooling tower consists of a water collection tank, a ventilation tower, water distribution pipes, a fan, and a water separator. Cooling water carrying waste heat is pumped into the cooling tower's distribution pipes. Sprayers on the pipes evenly distribute the water onto the packing material, forming a water film. Simultaneously, the water exchanges heat with the dry air entering from the bottom of the ventilation tower, evaporating and carrying away heat. The cooling water drips into the bottom collection tank for continued recycling. However, evaporation into the air is not endless. As air humidity increases, the air at the water vapor contact surface becomes saturated, preventing further evaporation. At this point, the fan is needed to push the hot, humid air to higher altitudes to prevent backflow and continuously draw in dry air from the bottom of the cooling tower, providing a constant flow of dry air. A water separator is also installed between the fan and the water distribution pipes to separate water droplets carried by the discharged hot, humid air from the air, reducing water loss.

[0004] During the operation of the cooling tower, it is difficult to control whether the water molecules inside the cooling tower can be completely evaporated and dispersed, causing the fans inside the cooling tower to be running for a long time, wasting power resources and hindering energy conservation and environmental protection in the cooling process of the wire drawing machine.

[0028] Please see Figure 1-8 This invention provides a technical solution: an energy-saving and environmentally friendly cooling tower for a wire drawing machine, comprising a cooling tower shell 101 and a conveying assembly for gas conveying mounted on the cooling tower shell 101. A water inlet pipe 102 is installed on the cooling tower shell 101. The conveying assembly includes a mounting frame 201 fixed to the upper end of the cooling tower shell 101, a mounting shaft 202 rotatably connected to the mounting frame 201, and a fan 203 mounted on the mounting shaft 202. A driving assembly for driving the mounting shaft 202 is provided on the mounting frame 201. A transmission assembly for energy-saving driving of the driving assembly is provided on the water inlet pipe 102. During the entire fan 203 driving process, the fan 203 can only be driven when the hot air conveyed inside the water inlet pipe 102 reaches a certain flow rate. This achieves the goal of sending the hot and humid air inside the cooling tower shell 101 to the upper atmosphere to prevent backflow, avoiding the fan 203 being in a running state for a long time, reducing power consumption, and facilitating energy saving and environmental protection during the cooling process of the wire drawing machine.

[0029] The drive assembly includes a U-shaped frame 301 fixed to the upper end of the mounting bracket 201. A drive shaft 302 is rotatably connected to the U-shaped frame 301. A drive motor 303 for driving the drive shaft 302 is mounted on the upper end of the U-shaped frame 301. The drive shaft 302 is located above the mounting shaft 202 and is concentrically arranged. Through the driving action of the drive motor 303 and the transmission action between the mounting shaft 202 and the drive shaft 302, the fan 203 can be driven to rotate.

[0030] The transmission assembly includes a first splined shaft 401 and a second splined shaft 402, which are respectively fixed on the mounting shaft 202 and the drive shaft 302. A splined sleeve 403 is slidably connected to the second splined shaft 402. The splined sleeve 403 is provided with a moving component for moving the splined sleeve 403. Through the downward movement of the splined sleeve 403, both ends of the splined sleeve 403 are connected to the mounting shaft 202 and the drive shaft 302 respectively, thus completing the transmission connection between the mounting shaft 202 and the drive shaft 302.

[0031] The moving component includes an annular plate 501 sleeved on the outside of the spline sleeve 403. A first connecting plate 502 is fixed on the annular plate 501, and a second connecting plate 503 is fixed on the first connecting plate 502. A connecting component for connecting the second connecting plate 503 is provided on the water inlet pipe 102. A lifting component that is pushed up and down by the second connecting plate 503 is provided above the water inlet pipe 102. The spline sleeve 403 can be moved by the second connecting plate 503, the first connecting plate 502 and the annular plate 501.

[0032] The connecting assembly includes multiple first sleeves 601 fixed to the outside of the water inlet pipe 102. Each first sleeve 601 is slidably connected to a first slide rod 602. The other end of the first slide rod 602 is fixed to a second connecting plate 503. A first spring 603 is sleeved on the side wall of each first sleeve 601. The first sleeve 601 and the first slide rod 602 guide the second connecting plate 503 after it is subjected to force. The first spring 603 facilitates the reset movement of the second connecting plate 503 after it is subjected to force.

[0033] The lifting assembly includes a push plate 701 located on one side of the second connecting plate 503. The push plate 701 has an inclined groove 702, and a sliding pin 703 is slidably connected to the inclined groove 702. The sliding pin 703 is fixed to the second connecting plate 503. A strip plate 704 is fixed to one end of the push plate 701. A pushing assembly for pushing the strip plate 704 is provided on the water inlet pipe 102. A guiding assembly for guiding the strip plate 704 after it is pushed is provided on the second connecting plate 503. The pushing assembly and the guiding assembly drive the strip plate 704. 4. The strip plate 704 moves towards the second connecting plate 503 under force. During the movement of the strip plate 704, it drives the push plate 701 to move synchronously. During the movement of the push plate 701, through the interaction between the inclined groove 702 and the sliding pin 703 and the guiding effect of the connecting components on the second connecting plate 503 after being subjected to force, the second connecting plate 503 is driven to move downward under force. During the movement of the second connecting plate 503, through the connection between the first connecting plate 502 and the annular plate 501, the spline sleeve 403 is driven to move downward synchronously.

[0034] The pushing assembly includes a pushing shaft 901 rotatably connected to the water inlet pipe 102. A disk 902 is fixed at the upper end of the pushing shaft 901. Multiple extrusion components are arranged in a circular array on the disk 902. A bearing 903 is fixed on the water inlet pipe 102 and is sleeved on the outside of the pushing shaft 901. A rotating assembly for rotating the pushing shaft 901 is arranged inside the water inlet pipe 102.

[0035] The extrusion assembly includes a sleeve 1001, one end of which is rotatably connected to the outside of a disc 902. A round rod 1002 is slidably connected to the sleeve 1001, and an extrusion ball 1003 is fixed to one end of the round rod 1002. A second spring 1004 for connecting the round rod 1002 is installed inside the sleeve 1001. During the rotation of the rotating shaft 1101, the disc 902 at one end of the push shaft 901 is driven to rotate synchronously. During the rotation of the disc 902, under the action of centrifugal force, the round rods 100... 2. The rods slide on each sleeve 1001 respectively. As the disc 902 rotates at a faster speed, the centrifugal force on each rod 1002 increases, and the rods move further outward inside the sleeve 1001. As the rods move further, the extrusion ball 1003 at one end of the rod 1002 abuts against the strip plate 704. Through the interaction between the extrusion ball 1003 and the strip plate 704 and the guiding effect of the guide assembly, the strip plate 704 is driven to move towards the second connecting plate 503.

[0036] The guiding assembly includes multiple second sleeves 801 fixed on the second connecting plate 503. A second slide rod 802 is slidably connected to each second sleeve 801. The other end of the second slide rod 802 is fixed to the strip plate 704. A third spring 803 is sleeved on the side wall of each second sleeve 801. The strip plate 704 is guided by each second sleeve 801 and the second slide rod 802 after being subjected to force. The third spring 803 facilitates the reset movement of the strip plate 704 after being subjected to force.

[0037] The rotating assembly includes a rotating shaft 1101 rotatably connected inside the water inlet pipe 102. One end of the rotating shaft 1101 is fixed to one end of the push shaft 901. A fan blade 1102 is fixed on the rotating shaft 1101. A guide plate 12 is fixed inside the water inlet pipe 102. During the process of hot air being transported to the interior of the cooling tower shell 101 through the water inlet pipe 102, the hot air transported inside the water inlet pipe 102 is guided by the guide plate 12 inside the water inlet pipe 102 so that the hot air only passes through one side of the fan blade 1102. During the passage of hot air, the fan blade 1102 and the rotating shaft 1101 are driven to rotate by the pushing pressure of the gas.

[0038] Working principle: When cooling the wire drawing machine, the hot air generated during the wire drawing machine production process is transported towards the interior of the cooling tower shell 101 through the water inlet pipe 102. During the process of the hot air being transported towards the interior of the cooling tower shell 101, the drive shaft 302 and the mounting shaft 202 are disconnected. At this time, the drive motor 303 cannot drive the fan 203 at one end of the mounting shaft 202 to rotate.

[0039] Furthermore, during the process of hot air being transported towards the interior of the cooling tower shell 101 through the water inlet pipe 102, the hot air transported inside the water inlet pipe 102 is guided by the flow guide plate 12 inside the water inlet pipe 102, so that the hot air only passes through one side of the fan blade 1102. During the passage of the hot air, the fan blade 1102 and the rotating shaft 1101 are driven to rotate by the pushing pressure of the gas. During the rotation of the rotating shaft 1101, the disc 902 at one end of the push shaft 901 is driven to rotate synchronously. During the rotation of the disc 902, under the action of centrifugal force, each round rod 1002 slides on each sleeve 1001 respectively.

[0040] When the flow rate of heated air transported on the inlet pipe 102 increases, under the action of gas pressure, the rotating shaft 1101, the push shaft 901, and the disc 902 are subjected to greater force and their rotation speed increases. As the disc 902 rotates at a faster speed, the centrifugal force on each rod 1002 increases, causing it to move further outward within the sleeve 1001. During this further movement, the extrusion ball 1003 at one end of the rod 1002 abuts against the strip plate 704. Through the interaction between the extrusion ball 1003 and the strip plate 704, and the guiding effect of the guide assembly, the strip plate 704 is driven to move towards the second connecting plate 503. During the movement of the strip plate 704, the push plate 701 moves synchronously. During the movement of the push plate 701, through the interaction between the inclined groove 702 and the sliding pin 703, and the guiding effect of the connecting assembly on the second connecting plate 503 after being subjected to force, the second connecting plate 503 is driven to move towards the second connecting plate 503. The second connecting plate 503 moves downward under force. During the movement of the second connecting plate 503, the spline sleeve 403 moves downward synchronously through the connection between the first connecting plate 502 and the annular plate 501. Through the downward movement of the spline sleeve 403, both ends of the spline sleeve 403 are connected to the mounting shaft 202 and the drive shaft 302 respectively, completing the transmission connection between the mounting shaft 202 and the drive shaft 302. At this time, through the driving action of the drive motor 303 and the transmission action between the mounting shaft 202 and the drive shaft 302, the fan 203 can be driven to rotate. Therefore, during the entire process of driving the fan 203, the fan 203 can only be driven when the hot air transported inside the water inlet pipe 102 reaches a certain flow rate. This achieves the goal of sending the hot and humid air inside the cooling tower shell 101 to the upper atmosphere to prevent backflow, avoiding the fan 203 from being in the starting state for a long time, reducing power consumption, and facilitating energy saving and environmental protection during the cooling process of the wire drawing machine.
