[0028] The method for preparing the ceramic fiber monolithic module by using any one of the preparation devices comprises the following steps:

[0029] S1, melting into liquid:

[0030] The material is poured into the melting device, the temperature is controlled to make the material into a molten state at high temperature, then the discharge nozzle is opened, and the molten material is transferred from the discharge nozzle into the fiber forming device;

[0031] S2, fiber forming and cotton collecting:

[0032] The molten material is cooled and solidified into fibers by the fiber forming device, the fibers are sucked from the fiber forming device into the condenser through the negative pressure in the condenser from the suction port for carding and cotton collecting, and then the fiber cotton blank is conveyed out of the condenser through the transmission plate on the transmission device;

[0033] S3, screening and needling:

[0034] The transmission plate is started to make the transmission plate transmit on the conveying track on the conveying table through the roller, when the weight of the fiber cotton blank on the transmission plate is in the normal range, the switching block defaults to connect the straight track with the conveying track, the transmission plate passes through the straight track to the good product channel, so that after the needle punching forming device is used for needle punching once, the counter counts as odd, the first tooth plate is extended to engage with the screw rod, the screw rod is rotated to the return track, and the transmission plate is turned to the return track.

[0035] After the transmission plate enters the turning room, the suction cup is lowered by the first telescopic rod to adsorb the fiber cotton blank at the front end of the transmission plate, the fiber cotton blank is in a lifted state, the driving block at the end of the transmission plate drives the turning lever to slide forward through the sliding block, so that the fiber cotton blank is turned over, when the turning lever compresses the spring and passes through the inductor, the suction cup is disabled, the turned fiber cotton blank falls back on the transmission plate, and when the turning lever is restored with the spring, the suction cup is restored to suction force again when passing through the inductor.

[0036] The transmission plate is turned back to the good product channel under the action of the magnetic diverter after being turned over, and is guided to the needling forming device for secondary needling, and after the needling is completed, the ceramic fiber module is counted by the counter, and if the number is even, the transmission plate is straight, the ceramic fiber module after needling is transmitted into the collecting box, and then is returned to the bottom of the condenser along the limiting plate surrounding the conveying track.

[0037] When the bulk weight of the fiber cotton blank exceeds 240kg / m 3 , and the deviation amplitude is 5kg / m 3 , the switching mechanism drives the switching block to make the curved track communicate with the conveying track, so that the transmission plate enters the defective product channel, without affecting the transmission of the next fiber cotton blank.

[0038] The beneficial effects of the present application are:

[0039] (1) The preparation device sets a straight track to divide the conveying path into a normal conveying path and a defective product conveying path, separates normal production and defective product recovery, and does not affect each other, thereby improving the efficiency of the ceramic fiber overall module preparation, and the defective product can be recycled in time, reducing the time cost of affecting the process flow of the next product due to the defective product.

[0069] The method for preparing the ceramic fiber monolithic module by using the preparation device includes the following steps:

[0070] S1, melting into liquid:

[0071] The material is poured into the melting device 1, the temperature is adjusted to make the material melt at high temperature, then the discharge nozzle 11 is opened, the molten material is transmitted from the discharge nozzle 11 to the spinning disc 22 inside the fiber forming device 2 through the hollow pipe 21;

[0073] The molten material is spun out of the through hole 221 by the centrifugal force of the spinning disc 22, and the condensing pipe 24 disperses cold air into the fiber forming device 2 through the micropore 241 to accelerate the cooling of the molten material to form fibers;

[0074] The condenser 3 sucks the fibers from the fiber outlet 23 of the fiber forming device 2 into the condenser 3 through the suction port 31 under the negative pressure inside the condenser 3 to perform carding and collecting, and then the fiber batt is transmitted out of the condenser 3 through the transmission plate 51 on the transmission device;

[0075] S3, screening and needling:

[0076] The engine is started to make the transmission plate 51 transmit on the transmission track 57 on the transmission table 5, when the weight of the fiber batt on the transmission plate 51 is within the normal range, the switching block 52 defaults to communicate the straight track 521 with the transmission track 57, and the transmission plate 51 passes through the straight track 521 to the good product channel 53;

[0081] Embodiment 2

[0082] The difference between this embodiment and embodiment 1 is that, as shown in Figure 8 , Figure 9 and Figure 10 , the intersection of the curved track 55 and the conveying track 57 is provided with a stop block 559, and the outer wall of the turnover chamber 551 is provided with a switch 558 for moving the stop block 559, which is located at the height of the driving block 511;

[0084] The difference between the preparation method of the ceramic fiber monolithic module using the above preparation device and embodiment 1 is that, by setting the stop block 559, the transmission plate 51 can be further prevented from being mistakenly inserted into the curved track 55 due to additional magnetic force during transmission on the conveying track 57, and the switch 558 can automatically adjust the position of the stop block 559 according to the stroke of the transmission plate 51, further improving the degree of automation;

[0085] By setting the length measuring device 541 to determine whether the length of the defective product exceeds 130mm, in the case of exceeding 5mm or more, the cutting knife 423 can be rotated in the direction of the defective product channel 54 by the engagement of the second toothed plate 542 and the screw rod 421, so as to cut the defective product fiber, and if the defective product meets the requirements after cutting, it can go through the needling process from the good product channel 53.

[0086] Embodiment 3

[0087] The difference between this embodiment and embodiment 1 is that, as shown in Figure 11 and Figure 12As shown, the cotton condenser 3 includes a cotton condenser housing 30, a dust cage 32 located inside the cotton condenser housing 30, a dust cage protective plate 33, a cotton stripping beater 34, and a hydraulic pipe 35.

The dust cage 32 is located below the cotton suction port 31, and the cotton stripping beater 34 is located at the lower right of the dust cage 32. The dust cage protective plate 33 is located below the dust cage 32 and the cotton stripping beater 34, and its four sides are fixedly connected to the inner wall of the cotton condenser housing 30. The rest of the structure of the cotton condenser 3 is existing technology.

[0088] like Figure 11 and Figure 12 As shown, a rotating plate 36 is provided at the top of the inner shell 30 of the cotton condenser. A dust collection cylinder 37 is detachably connected to the rotating plate 36. One end of the hydraulic pipe 35 passes through the inside of the dust collection cylinder 37. A cotton storage chamber 372 is provided inside the dust collection cylinder 37. A pressure cap 371 is provided at one end of the cotton storage chamber 372 near the suction port of the dust collection cylinder 37. The pressure cap 371 is rotatably connected to the side wall of the cotton storage chamber 372 through a torsion spring.

[0089] The method for preparing the integral ceramic fiber module using the above-mentioned preparation device differs from that in Example 1 in that, after the condensation is completed, the short fibers and lint remaining on the condenser 3 and dust cage 32 can be collected into the cotton storage chamber 372 under the hydraulic action of the hydraulic pipe 35. This can further improve the cleaning of the inside of the condenser 3 and prevent short fibers and lint from adhering to the next fiber product and affecting its quality.

9. A method for preparing a monolithic ceramic fiber module using any one of the preparation apparatuses described in claims 1 to 8, characterized in that, Includes the following steps: S1, Melting into a liquid: Pour the material into the melting device (1), adjust the temperature to make the material melt at high temperature, and then open the discharge nozzle (11) to transfer the molten material from the discharge nozzle (11) into the fiber forming device (2); S2, Fiber-forming cotton: Then, the molten material is cooled and solidified by the fiber forming device (2) to form fibers. Then, the fibers are drawn from the fiber outlet (23) of the fiber forming device (2) into the condenser (3) through the negative pressure inside the condenser (3) for carding and cotton collection. Then, the fiber cotton blank is conveyed out of the condenser (3) through the conveying plate (51) on the conveying device. S3, sieving needle punch: Start the transmission plate (51) so that the transmission plate (51) is transported on the transmission track (57) on the conveyor table (5) by the roller (512). When the weight of the fiber cotton blank on the transmission plate (51) is within the normal range, the switching block (52) defaults to connecting the straight track (521) with the transmission track (57). The transmission plate (51) goes to the good product channel (53) through the straight track (521). After being needled once by the needle punching device (4), the counter (41) records an odd number. Then, by extending the first tooth plate (411) and meshing with the screw (421), the screw (421) rotates towards the loop track (55), thereby pushing the transmission plate (51) to turn towards the loop track (55) and enter the loop track (55). After the transfer plate (51) enters the flipping chamber (551), the suction cup (552) moves down through the first telescopic rod (553) to adsorb the fiber cotton blank at the front end of the transfer plate (51). The fiber cotton blank is lifted up. The drive block (511) at the end of the transfer plate (51) drives the flipping rod (554) to slide forward through the slider (556), thereby flipping the fiber cotton blank. When the flipping rod (554) compresses the spring (555) and passes the sensor (557), the suction cup (552) fails. The flipped fiber cotton blank falls back onto the transfer plate (51). When the flipping rod (554) returns to its original position with the spring (555), it passes the sensor (557) again, causing the suction cup (552) to regain its suction force. After the transfer plate (51) is flipped over, it turns back to the good product channel (53) under the action of the magnetic deflector (56) and goes to the needle punching device (4) for secondary needle punching. After the needle punching is completed, it passes through the counter (41). When the counter (41) counts an even number, the transfer plate (51) goes straight and puts the needle punched ceramic fiber module into the collection box. Then it returns to the bottom of the cotton condenser (3) along the conveyor track (57) surrounded by the bottom limit plate (571). When the bulk density of fiber cotton exceeds 240 kg / m³ 3 And the deviation range is 5 kg / m 3 When the above occurs, the switching mechanism starts the drive switching block (52) to connect the curved track (522) with the conveying track (57), thereby allowing the transmission plate (51) to enter the defective channel (54) without affecting the transmission of the next fiber cotton blank.
