[0035] The cooperation of the primary nozzle 1 and the secondary nozzle 2 can spray the ceramic fiber multiple times, thereby improving the fiber formation rate of the ceramic fiber, and the primary nozzle 1 and the secondary nozzle 2 are both provided with a cavity for accommodating a coolant, and the walls of the primary pipe 1 and the secondary pipe 2 are both provided with a liquid inlet and a liquid outlet for connecting the cavity, so that a circulating water supply can be achieved to ensure that the water temperature in the cavity is not too high, further improving the cooling effect, and when the high-temperature molten ceramic fiber is sucked into the pipe, the temperature of the inner wall of the nozzle can be reduced, thereby improving the service life of the nozzle.

[0036] See also Figure 3-5As shown, the cleaning mechanism 3 includes a connecting seat 31, the primary nozzle 1 and the secondary nozzle 2 are both composed of a tube body and a nozzle, the connecting seat 31 is rotatably connected between the tube body and the nozzle, and the ends of the tube body and the nozzle are both provided with a clamping ring 12, and the connecting seat 31 is connected to the tube body and the nozzle through the clamping ring 12.

[0037] See also Figure 3-5 As shown, the connecting seat 31 extends to the inside of the primary nozzle 1 and the secondary nozzle 2 and is fixedly connected to the mounting seat 32. The mounting seat 32 is provided with an annular groove. The mounting seat 32 located in the primary nozzle 1 is slidably connected to a connecting rod 33 through the annular groove. The connecting rod 33 is in contact with the inner wall of the tube body. The end of the connecting rod 33 away from the mounting seat 32 is fixedly connected to a mounting ring 34, and the mounting ring 34 is connected to fan blades 35 distributed in a circle.

[0038] See also Figure 5 As shown, a telescopic rod 36 is slidably connected to the mounting seat 32 in the secondary nozzle 2, and the end of the telescopic rod 36 is connected to the mounting ring 34. A guide cover 37 is connected to the mounting ring 34 in the secondary nozzle 2. A plurality of air holes distributed in a circular pattern are provided on the surface of the guide cover 37. The guide cover 37 is located directly in front of the fan blades 35. The secondary nozzle 2 is connected to an air inlet pipe 5.

[0039] See also Figure 4 As shown, a plurality of connecting pipes 4 distributed in a circle are connected to the connecting seat 31, the ends of the connecting pipes 4 extend into the interior of the pipe body and are connected to the pipe body, a valve is provided on the connecting pipe 4 for controlling the closing and opening of the connecting pipe 4, and a cleaning agent is placed in the connecting pipe 4 so that it can flow into the nozzle to clean the nozzle.

[0040] The cleaning mechanism 3 is provided to solve the problem of nozzle blockage. During the spraying process, ceramic fibers are sprayed out through the secondary nozzle 2, which may easily cause blockage inside the secondary nozzle 2. After the primary nozzle 1 is used for a long time, ceramic fibers and impurities are also easily deposited in the nozzle, thereby affecting the normal use of the nozzle.

[0041] During the spraying process, the high-speed flowing compressed gas blows toward the blades 35, driving the blades 35 to rotate, thereby driving the mounting ring 34 and the connecting rod 33 to rotate. Since the primary nozzle 1 sprays outward, the ceramic fibers are usually not guided into the pipeline, and the blades 35 are located at a position far away from the nozzle of the primary nozzle 1, so the blades will not be entangled with the ceramic fibers to cause blockage. The blades 35 in the secondary nozzle 2 are connected to the telescopic rod 36. When the high-speed gas blows toward the blades 35, it first blows onto the guide cover 37, and the guide cover 37 moves together with the blades 35 connected thereto. The guide cover 37 is arranged at the same time to guide the ceramic fibers to the outside of the fan blades 35, and the high-speed gas is blown toward the fan blades from the air holes opened on the surface of the guide cover 37, so that the fan blades 35 rotate. As the fan blades 35 rotate, the connecting rod 33 connected to the fan blades 35 is driven to rotate, and the connecting rod 33 scrapes the ceramic fibers attached to the inner wall of the nozzle. After the fiberization of the ceramic fibers is completed, the cleaning agent can be introduced through the connecting pipe 4, and the inner wall of the nozzle is scraped with the connecting rod 33, so that the nozzle is thoroughly cleaned, and the cleaned residue is blown out of the nozzle by compressed gas.

[0042] See also Figure 7 , 8 As shown, an upper base plate 8 is provided below the primary nozzle 1 and the secondary nozzle 2, and a synchronization mechanism 6 is installed on the upper base plate 8. The synchronization mechanism 6 includes a moving seat 61, and the moving seat 61 is composed of a moving plate 601, a support rod 602 and a collar 603. The moving plate is slidably connected to the upper base plate 8, the collar is fixedly connected to the primary nozzle 1 and the secondary nozzle 2, and the support rod is fixedly connected between the collar and the moving plate.

[0043] See also Figure 7 As shown, the synchronization mechanism 6 also includes a synchronization gear 62, which is rotatably connected to the upper base plate 8. The moving seats 61 located on the primary nozzle 1 and the secondary nozzle 2 are fixedly connected with racks 63, and one end of the rack 63 away from the fixedly connected moving seat 61 is slidably connected to the other moving seat 61. The two racks 63 are both engaged with the synchronization gear 62. A cylinder 65 is provided below the upper base plate 8, and the telescopic end of the cylinder 65 is fixedly connected to one of the moving seats 61. A positioning block 64 is provided on the upper base plate 8, and the positioning block 64 and the rack 63 are slidably connected.

[0044] The synchronous mechanism 6 is capable of driving the primary nozzle 1 and the secondary nozzle 2 to move at the same time, and under the action of the synchronous gear 62 and the rack 63, it is ensured that the primary nozzle 1 and the secondary nozzle 2 are always located on the same straight line, thereby avoiding adjusting the primary nozzle 1 and the secondary nozzle 2 separately, causing the center lines of the primary nozzle 1 and the secondary nozzle 2 to be at different positions, thereby preventing the ceramic fiber sprayed by the primary nozzle 1 from accurately entering the secondary nozzle 2.

[0045] The action process of the synchronization mechanism 6 is to first start the cylinder 65, the cylinder 65 drives the moving seat 61 connected thereto, and the moving seat 61 further drives the rack 63 connected thereto to move, and this rack 63 drives the synchronous gear 62 meshing therewith to rotate, thereby further driving another rack 63 meshing with the synchronous gear 62 to move, and finally drives the other moving seat 61 to move synchronously.

[0046] See also Figure 8 As shown, a lower base plate 9 is arranged below the upper base plate 8, and a driving mechanism 7 is arranged on the lower base plate 9. The driving mechanism 7 includes a first motor 71, and the first motor 71 is located below the upper base plate 8. A fixed frame 72 is fixedly connected to the output end of the first motor 71, and the fixed frame 72 is fixedly connected to the upper base plate 8. An arc seat 73 is arranged below the upper base plate 8, and a slider 74 is connected to the upper base plate 8.

[0047] See also Figure 8 As shown, the driving mechanism 7 also includes a second motor 701, and the second motor 701 is installed on the lower base plate 9. The output end of the second motor 701 is fixedly connected with a bidirectional screw rod 702. A fixed rail is installed on the lower base plate 9. The bidirectional screw rod 702 is rotatably connected in the fixed rail. The two ends of the bidirectional screw rod 702 are threadedly connected with a moving block 703 at positions with opposite thread directions. The moving block 703 is rotatably connected with a rotating rod 704. A motor seat 705 is provided at the bottom of the first motor 71, and the free end of the rotating rod 704 is rotatably connected to the motor seat 705.

[0048] The driving mechanism 7 is set up, which can synchronously drive the primary nozzle 1 and the secondary nozzle 2 to lift and adjust the angle, so that the ceramic fibers coming out of the furnace 11 are at a most suitable distance. Due to the influence of the instability of the slurry, the primary nozzle 1 and the secondary nozzle 2 are sometimes unable to spray directly into the slurry. The positions of the primary nozzle 1 and the secondary nozzle 2 are adjusted by the driving mechanism 7, so that the fiberization rate of the blown ceramic fibers is higher and the diameter is thinner.

[0049] When the furnace 11 is affected by vibration and the position of the slurry is offset, the first motor 71 is started, and the first motor 71 further drives the fixed frame 72 fixedly connected thereto to rotate, and the fixed frame 72 finally drives the upper base plate 8 to rotate, thereby driving the primary nozzle 1 and the secondary nozzle 2 on the upper base plate 8 to rotate, and the arc seat 73 and the slider 74 are provided to limit the position, and the arc seat 73 is consistent with the rotation trajectory of the upper base plate 8, thereby limiting the upper base plate 8.

[0050] When it is necessary to adjust the relative distance between the primary nozzle 1 and the secondary nozzle 2 and the melting furnace 11, the second motor 701 is started, and the second motor 701 drives the bidirectional screw rod 702 fixedly connected thereto to rotate, and the bidirectional screw rod 702 further drives the moving block 703 threadedly connected thereto to move in the fixed rail, and as the moving block 703 moves, the rotating rod 704 rotatably connected to the moving block 703 is driven to rotate, and the rotating rod 704 ultimately drives the motor base 705 rotatably connected thereto and the first motor 71 on the motor base 705 to move, and the first motor 71 is connected to the primary nozzle 1 and the secondary nozzle 2 through the upper base plate 8, so the primary nozzle 1, the secondary nozzle 2 and the first motor 71 move synchronously.

[0051] The present invention also includes a blowing method for a ceramic fiber forming device, the method comprising the following steps:

[0052] Step 1: The molten ceramic fiber liquid falling from the melting furnace 11 is first sprayed through the primary nozzle 1. The primary nozzle 1 and the secondary nozzle 2 are provided with compressed gas through a compressor. The compressed gas of the primary nozzle 1 is introduced from the end away from the melting furnace 11, and the compressed gas is introduced into the middle part of the secondary nozzle 2;

[0053] Step 2: The molten ceramic fiber is first sprayed through the primary nozzle 1, which blows the molten ceramic limit part into a fiber shape. Then, the ceramic fiber enters the secondary nozzle 2 under the action of the compressed air in the primary nozzle 1 and the negative pressure formed in the secondary nozzle 2;

[0054] Step three: The cooperation of the set driving mechanism 7 and the synchronization mechanism 6 can synchronously adjust the relative positions between the primary nozzle 1 and the secondary nozzle 2 and the furnace 11. The driving mechanism 7 can adjust the height, angle and relative distance between the primary nozzle 1 and the secondary nozzle 2.
