DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0014] Embodiment 1: Refer to Figure 1 and Figure 2 , a centrifugal fiber forming device, relates to the technical field of fiber processing equipment, and mainly comprises a base 1, a centrifugal box 2, a centrifugal roller 8, a plugging structure, a reciprocating structure, a cooling structure and a collection structure.

[0015] Refer to Figure 2 and Figure 3 , the base 1 serves as the support foundation of the entire device, and the centrifugal box 2 is fixed on the top of the base 1 through supporting legs. The centrifugal box 2 is the main working cavity of the device, and the inside of the centrifugal box 2 is provided with key components for realizing centrifugal fiber forming.

[0016] Refer to Figures 2-4 , the centrifugal roller 8 is rotatably connected to the inner wall of the top of the centrifugal box 2 through a rotating bearing. The centrifugal roller 8 is the core component of centrifugal fiber forming, and the outer wall of the centrifugal roller 8 is provided with a plurality of spray hole groups from top to bottom, and each spray hole group is composed of a plurality of spray holes 9 arranged in a ring on the outer wall of the centrifugal roller 8. The molten raw material is injected into the inside of the centrifugal roller 8 through the cooperation of the U-shaped groove pipe 7 and the hopper, and under the action of centrifugal force, the raw material is thrown out from the spray holes 9 to form fibers.

[0017] Refer to Figure 3 and Figure 4In order to avoid the molten raw material flowing out of the injection hole 9 when injecting the raw material into the centrifugal roller 8, the present application sets a blocking structure on the outer wall of the centrifugal roller 8. The blocking structure mainly includes a plurality of sealing rings 10 slidingly sleeved on the outer wall of the centrifugal roller 8, wherein the cross-sectional shape of the sealing ring 10 can adopt a rectangular, trapezoidal or semicircular design, wherein the trapezoidal cross-section can enhance the sealing fit with the outer wall of the centrifugal roller 8, and the semicircular cross-section can reduce the sliding friction resistance, and the sealing ring 10 corresponds to the nozzle group for closing the corresponding injection hole 9.

[0018] Referring to Figure 3 and Figure 4 , the blocking structure further includes a fixed ring 12 fixedly sleeved on the outer wall of the centrifugal roller 8. The upper and lower adjacent two sealing rings 10 are fixedly connected by a plurality of fixed rods 11, so as to form a whole of the plurality of sealing rings 10. The top of the fixed ring 12 is slidingly connected with a plurality of centrifugal blocks 13, the side close to the centrifugal roller 8 of the plurality of centrifugal blocks 13 is fixedly provided with a plurality of pull ropes 17, and the bottom end of the plurality of pull ropes 17 penetrates through the fixed ring 12 and is fixedly connected with the uppermost sealing ring 10. When the centrifugal roller 8 is stationary, the plurality of sealing rings 10 are reset under the action of gravity to close the injection hole 9. When the centrifugal roller 8 starts to rotate, as the rotating speed gradually increases, when the rotating speed reaches a certain threshold, the centrifugal block 13 moves outward under the action of centrifugal force. The centrifugal block 13 drives the sealing ring 10 to move upward through the pull rope 17, thereby releasing the closure of the injection hole 9. At this time, the raw material in the centrifugal roller 8 is thrown out to the outside through the injection hole 9 under the action of centrifugal force, and then the raw material is drawn into fibers, wherein the plurality of shapes of the centrifugal block 13: 1. Rectangular centrifugal block: adopts a cuboid structure, simple to process and uniform in centrifugal force acting surface, suitable for medium and low speed working conditions; 2. Trapezoidal centrifugal block: the cross-section is trapezoidal, the gravity center moves downward to enhance the centrifugal force response speed, suitable for high speed scene; 3. Arc-shaped centrifugal block: the outer surface is circular arc, the friction resistance is smaller when slidingly matched with the inner wall of the fixed ring 12, reducing the risk of jamming; 4. Triangular centrifugal block: the tip points to the centrifugal direction, reducing air resistance, suitable for ultra-high speed centrifugation (>3000 rpm) working condition; 5. Streamlined centrifugal block: imitates the aerodynamic curved surface design, which can reduce the turbulent noise during rotation and improve the quiet performance of the equipment.

[0019] Referring to Figure 5 , in order to ensure the stability and accuracy of the pull rope 17 during movement, a plurality of guide wheels 15 are rotatably connected to the top of the fixed ring 12 through a base for guiding the pull rope 17. The outer wall of the guide wheel 15 is provided with a limiting groove 16 for limiting the pull rope 17 to prevent the pull rope 17 from deviating during movement.

[0020] Referring to Figure 5In addition, the outer wall of the fixed ring 12 is also fixed with a plurality of stop blocks 14 through bolts. When the centrifugal roller 8 is stationary, the centrifugal block 13 is moved under the action of the pull rope 17, and the stop block 14 can be used to limit the movement of the centrifugal block 13 to prevent the centrifugal block 13 from moving too much.

The reciprocating structure mainly comprises a driving shaft 34 rotating on one side of the centrifugal box 2 through a base and a sliding rod 28 sliding through the inner wall of one side of the centrifugal box 2.

[0022] With reference to Figure 6 and Figure 7 , the top of the sliding rod 28 is fixed with a pin shaft 29, the bottom of the fixed ring 12 is provided with a track groove 30, the top of the pin shaft 29 extends into the track groove 30 and is in sliding cooperation with the track groove 30. When the fixed ring 12 rotates, the sliding rod 28 can be driven to reciprocate linearly through the cooperation of the pin shaft 29 and the track groove 30. One side of the sliding rod 28 is fixed with a rack 31 located on one side of the centrifugal box 2, and one side of the centrifugal roller 8 is fixed with a spur gear 33 through a rack. The input shaft of the spur gear 33 is fixed with a gearbox 32 engaged with the rack 31. The sliding rod 28 can drive the gearbox 32 to rotate through the engagement between the rack 31 and the gearbox 32. The spur gear 33 is used to adjust the rotating speed of the gearbox 32 and is output through the driving shaft 34. The bottom end of the driving shaft 34 is fixed with a rotating disc 35, and the bottom of the rotating disc 35 deviated from the center of the one side is fixed with a pin rod 36. The top of the collection plate 25 is provided with a sliding groove 37 in sliding cooperation with the pin rod 36. When the rotating disc 35 drives the pin rod 36 to revolve, the collection plate 25 can be driven to reciprocate linearly under the cooperation of the sliding groove 37.

[0023] Through the setting of the reciprocating structure, the fibers falling from the discharge pipe 18 can be alternately folded and laid on the collection plate 25, thereby realizing uniform collection of the fibers.

[0024] With reference to Figure 2 and Figure 8 , in order to quickly cool the spun fibers, the present application provides a cooling structure in the centrifugal box 2. The cooling structure mainly comprises an air outlet ring 19 and a cooling water ring 22. The top inner wall of the centrifugal box 2 is fixed with the air outlet ring 19 through a connecting rod, and the top inner wall of the centrifugal box 2 is fixed with an air injection hole 20 penetrating through. One end of the air injection hole 20 is in communication with an external air blower, and the other end is fixedly extended into the air outlet ring 19 for injecting cold air from the outside into the air outlet ring 19. The bottom of the air outlet ring 19 is provided with a plurality of first through holes 21 for blowing the cold air in the air outlet ring 19 downward. The cold air not only can cool the fibers, but also can discharge the fibers downward.

[0025] With reference to Figure 2 and Figure 8 , the inner wall of the centrifugal box 2 is fixed with a cooling water ring 22, and a liquid injection pipe 24 is fixedly penetrated on one side of the centrifugal box 2. One end of the liquid injection pipe 24 is connected with the cooling water source outside, and the other end is fixedly communicated with the cooling water ring 22, which is used for injecting cooling water into the cooling water ring 22. The bottom of the cooling water ring 22 is provided with a plurality of second through holes 23 for spraying cooling water downward to further water cool the fibers.

[0026] With reference to Figure 2 and Figure 6 , in addition, a conical discharge ring 43 is fixed in the centrifugal box 2 below the centrifugal roller 8, and the inner wall of the conical discharge ring 43 is designed as a corrugated or stepped surface in addition to the basic angle of 30°-60°. The corrugated structure can prolong the contact time of the fibers with the cooling water curtain, and the inner diameter of the conical discharge ring 43 decreases from top to bottom. The cooling water ring 22 is located above the conical discharge ring 43. The bottom end of the conical discharge ring 43 is fixed with a discharge pipe 18 which penetrates the inner wall of the bottom of the centrifugal box 2, and the discharge pipe 18 cooperates with the collection groove 27 to collect the fibers.

[0027] When the centrifugal roller 8 rotates to form fibers by centrifugation, the fibers fall on the inner wall of the conical discharge ring 43 and are guided to the middle by the inner wall of the conical discharge ring 43, and then discharged through the discharge pipe 18. At the same time, the cooling water sprayed by the cooling water ring 22 falls on the conical discharge ring 43 to form a water curtain, so that the conical discharge ring 43 can make the cooling water fully contact with the fibers during guiding the fibers.

[0028] With reference to Figure 6 , the collection structure mainly includes a collection plate 25 which slides on the top of the base 1, and the top of the collection plate 25 is provided with a collection groove 27 for collecting fibers. The collection plate 25 moves linearly back and forth under the drive of the reciprocating structure, so that the fibers can be evenly laid in the collection groove 27.

[0029] With reference to Figure 1 , Figure 2 and Figure 9 , in order to protect the fibers when the collection plate 25 moves back and forth to collect the fibers, and avoid impurities outside adhering to the fibers, a protective gauze 26 is slidably fitted on the top of the collection plate 25, and the protective gauze 26 is slidably sleeved on the outer wall of the discharge pipe 18.

A first bevel gear 4 is fixedly sleeved on the outer wall of the transmission pipe 3, and the first bevel gear 4 meshes with the second bevel gear 6. Driven by the drive motor 5, the transmission pipe 3 and the centrifugal roller 8 can rotate, thereby completing the centrifugal fiber forming operation.

A hopper is rotatably connected to the top of the transmission pipe 3, and the hopper is fixed to the top of the centrifuge box 2 by an L-shaped support rod. The hopper and the U-shaped groove tube 7 cooperate to inject molten raw materials into the centrifugal roller 8.

[0032] Reference Figure 2 and Figure 6 In order to protect components such as rack 31, spur gear 33 and gearbox 32, a protective box is fixed to one side of centrifuge 2 by bolts.

[0033] Example 2: Reference Figure 1 , Figure 8 and Figure 9 An improvement upon Embodiment 1 is made as follows: The top of the base 1 is provided with a storage tank 39, and the bottom inner wall of the collection tank 27 is provided with multiple drainage holes 38 for draining cooling water from the collection tank 27 into the storage tank 39. A pump 40 is fixed to one side of the base 1 via a frame. A first flexible hose 41, connected to the storage tank 39, is fixed to the inlet end of the pump 40, and a second flexible hose 42 is fixed to the outlet end of the pump 40, with one end of the second flexible hose 42 fixedly connected to the cooling water ring 22. The pump 40 enables the cooling water to be recycled and reused, avoiding waste.

[0034] A method of using a lightweight mineral wool fiber centrifugal fiber forming device includes the following steps: S1. Molten raw material is injected into centrifugal roller 8 through the U-shaped groove pipe 7 and the hopper. Since the nozzle 9 is blocked by the sealing ring 10, the raw material can be stably stored in the centrifugal roller 8, avoiding waste. When centrifugal fiber forming is required, the drive motor 5 drives the transmission pipe 3 and centrifugal roller 8 to rotate through the meshing between the first bevel gear 4 and the second bevel gear 6. As the speed of centrifugal roller 8 gradually increases, when the speed reaches a certain threshold, the centrifugal block 13 moves outward under the action of centrifugal force. The centrifugal block 13 drives the sealing ring 10 to move upward through the pull rope 17, releasing the seal on the nozzle 9. At this time, the raw material in the centrifugal roller 8 is thrown outward through the nozzle 9 under the action of centrifugal force, and then the raw material is drawn into fibers. S2, in order to ensure that the raw materials can be quickly formed, the outside air blower injects cold air into the air outlet ring 19 through the air injection hole 20, the cold air blows down through the first through hole 21, because the fibers move outward under the action of centrifugal force, and the fibers are in contact with the inner wall of the discharge ring 43, so the cold air can discharge the fibers downward along the inner wall of the discharge ring 43, in addition, the outside water pump 40 injects cooling water into the cooling water ring 22 through the liquid injection pipe 24, the cooling water sprays the conical discharge ring 43 through the second through hole 23, and the inner diameter of the bottom end of the conical discharge ring 43 is tapered, so the cooling water forms a water curtain on the inner wall of the conical discharge ring 43, so when the fibers pass through the conical discharge ring 43 and discharge downward, the fibers can be further cooled by the cooling water; S3, the fibers fall on the collection plate 25 through the discharge pipe 18, and the collection is completed, in order to ensure that the collection plate 25 can uniformly complete the collection, when the fixed ring 12 rotates, the sliding rod 28 is driven to reciprocate linearly through the cooperation of the pin shaft 29 and the track groove 30, the sliding rod 28 drives the straight gear 33 to rotate through the meshing between the rack 31 and the straight gear 33, the gearbox 32 is used to adjust the rotating speed of the straight gear 33 and is output through the driving shaft 34, thereby driving the rotating disc 35 to rotate, the rotating disc 35 can drive the collection plate 25 to reciprocate linearly through the cooperation of the pin rod 36 and the sliding groove 37, thereby enabling the fibers falling from the discharge pipe 18 to be alternately folded and laid on the collection plate 25; S4, in addition, the water flowing downward on the conical discharge ring 43 falls into the collection groove 27 along with the fibers, and enters the storage groove 39 through the liquid leakage hole 38, at this time, the cooling water collected in the storage groove 39 is pumped into the cooling water ring 22 by the pump 40 for repeated use; when the fibers in the collection groove 27 need to be taken out, the protective gauze 26 is pushed upward to remove the shielding and protection of the fibers by the protective gauze 26 (to avoid impurities adhering to the fibers), at this time, the fibers can be taken out.

[0035] However, the working principle and wiring method of the pump 40 and the driving motor 5 are common, as known to those skilled in the art, which belong to conventional means or common knowledge, and will not be described here. Those skilled in the art can make any selection according to their needs or convenience.

10. A method of using a lightweight mineral wool fiber centrifugal fiber forming device, applied to the lightweight mineral wool fiber centrifugal fiber forming device as described in claim 9, characterized in that... Includes the following steps: S1. Molten raw material injection and centrifugal fiber formation: Molten raw material is injected into the centrifugal roller (8) through the U-shaped groove tube (7). The sealing ring (10) seals the nozzle (9) to store the raw material. When the drive motor (5) is started, it drives the transmission tube (3) and the centrifugal roller (8) to rotate through the meshing of the first bevel gear (4) and the second bevel gear (6). After the speed of the centrifugal roller (8) reaches the threshold, the centrifugal block (13) is moved outward by centrifugal force and drives the sealing ring (10) to move upward through the pull rope (17), releasing the sealing of the nozzle (9) and allowing the raw material to be centrifuged and thrown out through the nozzle (9) to form fibers. S2. Simultaneous operation of dual cooling systems: The blower injects cold air into the air outlet ring (19) through the air injection hole (20). The cold air blows downward through the first through hole (21). As the fibers move outward under the action of centrifugal force and the fibers abut against the inner wall of the discharge ring (43), the cold air blows downward and can discharge the fibers along the inner wall of the discharge ring (43). At the same time, the water pump (40) injects cooling water into the cooling water ring (22) through the liquid injection pipe (24). The cooling water is sprayed onto the conical discharge ring (43) through the second through hole (23) and forms a water curtain on its inner wall to further cool the passing fibers. S3. Uniform fiber collection control: Fibers fall into the collection plate (25) through the discharge pipe (18); when the fixed ring (12) rotates, it drives the sliding rod (28) to move back and forth through the pin (29) and the track groove (30). The sliding rod (28) drives the spur gear (33) to rotate through the rack (31) and the spur gear (33). After the gearbox (32) adjusts the speed, it outputs through the drive shaft (34) to drive the rotating disk (35) to rotate. The rotating disk (35) drives the collection plate (25) to move back and forth through the pin (36) and the sliding groove (37), so that the fibers are alternately folded and laid. S4. Cooling water circulation and fiber removal: Water and fibers in the conical discharge ring (43) fall into the collection tank (27), enter the storage tank (39) through the leakage hole (38), and the cooling water is pumped back into the cooling water ring (22) for recycling by the pump (40); push the protective net (26) upward to remove it from covering the fibers and remove the fibers in the collection tank (27).
