Technical Field
[0001] This utility model belongs to the technical field of spraying devices, specifically relating to a nano-coating spraying device for the surface of nano-high calcium wire. Background Technology
[0002] Metallic calcium, as a highly reactive metal, is a powerful reducing agent. Its main uses include: deoxidation, desulfurization, and degassing in steelmaking and cast iron; deoxidation in the production of metals such as chromium, niobium, samarium, thorium, titanium, uranium, and vanadium; as an alloying material, it is used in the lead industry to produce maintenance-free car batteries, where calcium-lead alloys can increase strength, improve corrosion resistance, and creep resistance; it is used as a deoxidizing and reducing agent in various non-ferrous metals, rare earth metals, and refractory metals; as an alloying agent (blending agent) in the production of non-ferrous alloys such as aluminum, beryllium, copper, lead, and magnesium; and as a deoxidizing agent in the production of high-purity steel and non-ferrous alloys. Calcium metal is also used to create calcium wire by sealing it, which is then fed into the metallurgical process.
[0003] When preparing high-calcium nanowires, it is necessary to use spraying equipment to spray nano-coatings onto the surface of the calcium wires. However, conventional spraying equipment is difficult to achieve complete coverage of the calcium wire surface, resulting in certain blind spots and affecting the spraying effect. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a nano-coating spraying device for the surface of high-calcium nanowires. Each atomizing nozzle of this device can spray the calcium wires from different angles in a cyclic manner, thereby further increasing the coverage area of the coating on the surface of the calcium wires, greatly reducing the blind zone of spraying, improving the spraying effect, enabling the coating to be more evenly distributed on the surface of the calcium wires, and reducing the phenomenon of uneven spraying thickness.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano-coating spraying device for the surface of high-calcium nanofibers, comprising a workbench, a first support mounted on the top of the workbench, a spraying chamber and a drying chamber mounted on the top of the first support, a diversion pipe extending through and mounted on the side of the spraying chamber, the diversion pipe having multiple liquid outlets located inside the spraying chamber, one end of each liquid outlet being connected to a booster pump, one end of the booster pump being fixed to a fixed ring, and a rotating hollow ring rotatably mounted on the outer side of the fixed ring. A gear ring is fitted on the outer side of the spraying chamber. A drive device is installed on both the side and the inner side of the spraying chamber. Multiple atomizing nozzles are fixedly arranged in a ring array on the inner surface of the rotating hollow ring. A heating tube mounting base is fixedly installed on the inner side of the drying chamber. An electric heating tube is fixedly installed on the top of the heating tube mounting base. A second bracket is fixedly installed on the top of the workbench. A paint storage tank is installed on the top of the second bracket. An output pipe is connected to the bottom of the paint storage tank. An electric control valve is connected to the bottom of the output pipe. A winding mechanism is installed on the side of the workbench.
[0006] The beneficial effects of this invention are as follows: At the start of spraying, the electric control valve is opened, allowing the paint inside the paint storage tank to enter the distribution pipe through the output pipe. After being pressurized by various booster pumps, it is input into the space inside the rotating hollow ring. Multiple atomizing nozzles, arranged in a ring array on the inner surface of the rotating hollow ring, spray the paint evenly from different directions simultaneously onto the surface of the calcium wire. Simultaneously, the first motor is controlled to rotate, driving the first rotating shaft and gear to rotate at a constant speed. This drives the gear ring and the rotating hollow ring to rotate at a constant speed outside the fixed ring, thereby causing the atomizing nozzles to rotate as well. The arrangement of multiple sets of rotatable hollow rings allows each atomizing nozzle to spray the calcium wire from different angles in a cyclical manner, further increasing the paint coverage area on the calcium wire surface, greatly reducing blind spots, improving the spraying effect, and ensuring the paint is more evenly distributed on the calcium wire surface, while reducing uneven spraying thickness.
[0007] After the coating is applied, the calcium wire enters the drying chamber, where multiple sets of electric heating tubes work together to quickly dry the coating on the surface of the calcium wire.
[0008] For rotary spraying with atomizing nozzles:
[0009] As a further improvement to the above technical solution: the driving device includes a first motor installed on the side of the spraying chamber, one end of the first motor is fixedly connected to a first rotating shaft, and a gear is sleeved on the outer side of the first rotating shaft, the gear meshing with a gear ring.
[0010] The beneficial effects of this improvement are as follows: controlling the operation of the first motor, the first rotating shaft and gear are driven to rotate at a constant speed, thereby driving the gear ring and the rotating hollow ring to rotate at a constant speed outside the fixed ring, which in turn drives the atomizing nozzle to rotate. By setting multiple sets of rotatable rotating hollow rings, each atomizing nozzle can spray calcium wire from different angles in a cyclic manner.
[0011] For the control of this device:
[0012] As a further improvement to the above technical solution: a control device is installed on the side of the workbench.
[0013] The beneficial effects of this improvement are: a touch screen is provided on the top of the control device, and a PLC controller is provided inside the control device for controlling the device.
[0014] In order to guide the movement of calcium filaments:
[0015] As a further improvement to the above technical solution: a pulley bracket is installed on the top of the workbench, and two sets of pulleys are rotatably installed on the inner side of the pulley bracket.
[0016] The beneficial effect of this improvement is that the calcium wire passes between the upper and lower sets of pulleys, and the two sets of pulleys work together to guide the calcium wire's path.
[0017] To collect excess paint:
[0018] As a further improvement to the above technical solution: the bottom of the spraying chamber is connected to a discharge pipe, the bottom of the discharge pipe is connected to a residual material collection tank, and the bottom of the residual material collection tank is connected to a discharge valve.
[0019] The beneficial effects of this improvement are as follows: excess paint liquid in the spraying chamber slides downward under the action of gravity and is discharged into the residual material collection tank through the discharge pipe. By opening the discharge valve, the paint in the residual material collection tank can be discharged and collected.
[0020] To enable automatic winding of calcium wire:
[0021] As a further improvement to the above technical solution: the winding mechanism includes a winding drum mounting frame fixed to the workbench, a second motor is mounted on a rod on one side of the winding drum mounting frame, the output end of the second motor is rotatably connected to a second rotating shaft, a winding drum is sleeved on the outside of the second rotating shaft, and one end of the second rotating shaft is threadedly connected to a locking bolt.
[0022] The beneficial effects of this improvement are as follows: the second motor drives the second shaft to rotate, which in turn drives the winding drum to rotate, automatically pulling and winding the calcium wire. When the calcium wire on the outside of the winding drum is fully wound, the locking bolt can be unscrewed, the winding drum can be removed from the second shaft, and a new winding drum can be installed.
[0023] In order for the spool to rotate synchronously with the rotation of the second shaft:
[0024] As a further improvement to the above technical solution: the top and bottom of the second rotating shaft are provided with keyways, and the inner side of the winding drum is provided with a key.
[0025] The beneficial effect of this improvement is that, through the cooperation of the keyway and the key, the spool can rotate synchronously with the rotation of the second shaft.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0036] like Figure 1-7 As shown, a nano-coating spraying device for the surface of high-calcium nanofibers includes a workbench 1. A first support 2 is mounted on the top of the workbench 1. A spraying chamber 3 and a drying chamber 4 are mounted on the top of the first support 2. A diversion pipe 5 is installed through and installed on the side of the spraying chamber 3. The diversion pipe 5 has multiple liquid outlets located inside the spraying chamber 3. One end of each liquid outlet is connected to a booster pump 6. One end of the booster pump 6 is fixed to a fixed ring 7. A rotating hollow ring 8 is rotatably mounted on the outside of the fixed ring 7. A gear ring 9 is sleeved on the outside of the rotating hollow ring 8. The spraying chamber... A drive device is installed on both the side and the inside of the workbench 1. Multiple atomizing nozzles 13 are fixedly arranged in a ring array on the inner ring surface of the rotating hollow ring 8. A heating tube mounting base 15 is fixedly installed on the inner side of the drying chamber 4. An electric heating tube 16 is fixedly installed on the top of the heating tube mounting base 15. A second bracket 17 is fixedly installed on the top of the workbench 1. A paint storage tank 18 is installed on the top of the second bracket 17. An output pipe 19 is connected to the bottom of the paint storage tank 18. An electric control valve 20 is connected to the bottom of the output pipe 19. A winding mechanism 26 is installed on the side of the workbench 1.
[0037] At the start of spraying, the electronic control valve 20 is opened, allowing the paint inside the paint storage tank 18 to enter the diversion pipe 5 through the output pipe 19. After being pressurized by various booster pumps 6, the paint is input into the space inside the rotating hollow ring 8. Multiple atomizing nozzles 13, arranged in a ring array on the inner surface of the rotating hollow ring 8, spray the paint evenly from different directions simultaneously onto the surface of the calcium wire. At the same time, the first motor 10 is controlled to operate, driving the first rotating shaft 11 and gear 12 to rotate at a constant speed. This drives the gear ring 9 and the rotating hollow ring 8 to rotate at a constant speed outside the fixed ring 7, thereby causing the atomizing nozzles 13 to rotate as well. Through the arrangement of multiple sets of rotatable rotating hollow rings 8, each atomizing nozzle 13 can spray the calcium wire from different angles in a cyclical manner, thereby further increasing the coverage area of the paint on the surface of the calcium wire, greatly reducing the blind zone of spraying, improving the spraying effect, allowing the paint to be more evenly distributed on the surface of the calcium wire, and reducing the phenomenon of uneven spraying thickness.
[0038] After the coating is completed, the calcium wire enters the drying chamber 4. With the cooperation of multiple sets of electric heating tubes 16, the coating on the surface of the calcium wire can be dried quickly.
[0039] The driving device includes a first motor 10 installed on the side of the spraying chamber 3. One end of the first motor 10 is fixedly connected to a first rotating shaft 11. A gear 12 is sleeved on the outside of the first rotating shaft 11, and the gear 12 meshes with a gear ring 9.
[0040] The first motor 10 is controlled to operate, and the first rotating shaft 11 and gear 12 are driven to rotate at a constant speed, thereby driving the gear ring 9 and the rotating hollow ring 8 to rotate at a constant speed outside the fixed ring 7, which in turn drives the atomizing nozzle 13 to rotate. Through the setting of multiple sets of rotatable rotating hollow rings 8, each atomizing nozzle 13 can spray calcium wire from different angles in a cyclic manner.
[0041] A control device 14 is installed on the side of the workbench 1.
[0042] The top of the control device 14 is equipped with a touch screen, and the inside of the control device 14 is equipped with a PLC controller for controlling the device.
[0043] The top of the workbench 1 is equipped with a pulley bracket 21, and two sets of pulleys 22 are rotatably mounted on the inner side of the pulley bracket 21.
[0044] The calcium wire passes between two sets of pulleys 22, which work together to guide the calcium wire's path.
[0045] The bottom of the spraying chamber 3 is connected to a discharge pipe 23, the bottom of the discharge pipe 23 is connected to a residual material collection tank 24, and the bottom of the residual material collection tank 24 is connected to a discharge valve 25.
[0046] Excess paint in the spraying chamber 3 slides downward under gravity and is discharged into the residual material collection tank 24 through the discharge pipe 23. By opening the discharge valve 25, the paint in the residual material collection tank 24 can be discharged and collected.
[0047] The winding mechanism 26 includes a winding drum mounting frame 27 fixed to the workbench 1. A second motor 28 is mounted on one side of the winding drum mounting frame 27. The output end of the second motor 28 is rotatably connected to a second rotating shaft 29. A winding drum 30 is sleeved on the outside of the second rotating shaft 29. One end of the second rotating shaft 29 is threadedly connected to a locking bolt 31.
[0048] The second motor 28 drives the second shaft 29 to rotate, which in turn drives the winding drum 30 to rotate, automatically pulling and winding the calcium wire. When the calcium wire on the outside of the winding drum 30 is fully wound, the locking bolt 31 can be unscrewed, the winding drum 30 can be removed from the second shaft 29 and replaced with a new winding drum 30.
[0049] The second rotating shaft 29 is provided with keyways at both the top and bottom, and the winding drum 30 is provided with a key on its inner side.
[0050] The keyway and key work together to allow the spool 30 to rotate synchronously with the rotation of the second shaft 29.
[0051] The working principle and usage process of this utility model are as follows: When using this device, one end of the calcium wire is passed between two sets of pulleys 22 located on the left side of the drying chamber 4, allowing it to enter the inner side of the spraying chamber 3 for spraying. At the start of spraying, the electric control valve 20 is opened, allowing the paint inside the paint storage tank 18 to enter the diversion pipe 5 through the output pipe 19. After being pressurized by various booster pumps 6, it is input into the space inside the rotating hollow ring 8. Multiple atomizing nozzles 13 distributed in a ring array on the inner ring surface of the rotating hollow ring 8 spray the paint evenly, simultaneously spraying the surface of the calcium wire from different directions. At the same time, the first motor 10 is controlled to operate, driving the first rotating shaft 11 and gear 12 to rotate at a constant speed, thereby driving the gear ring 9 and the rotating hollow ring 8 to rotate at a constant speed outside the fixed ring 7, which in turn drives the atomizing nozzles 13 to rotate as well. Through the design of multiple sets of rotatable rotating hollow rings 8... The atomizing nozzles 13 are positioned so that each nozzle can spray the calcium wire from different angles in a cyclical manner, thereby increasing the coverage area of the coating on the surface of the calcium wire, greatly reducing the blind spots in the spraying, improving the spraying effect, and allowing the coating to be more evenly distributed on the surface of the calcium wire, reducing the phenomenon of uneven coating thickness. After the calcium wire is sprayed, it enters the drying chamber 4. With the cooperation of multiple sets of electric heating tubes 16, the coating on the surface of the calcium wire is dried quickly. After drying, the calcium wire exits from the right end of the drying chamber 4 and passes between the two sets of pulleys 22 located on the right side of the drying chamber 4. It is then wound around the outside of the winding drum 30. The second motor 28 drives the second rotating shaft 29 to rotate, which in turn drives the winding drum 30 to rotate, automatically pulling and winding the calcium wire. When the outside of the winding drum 30 is full of calcium wire, the locking bolt 31 can be unscrewed, the winding drum 30 can be removed from the second rotating shaft 29 and replaced with a new winding drum 30.
