[0001] This utility model relates to the field of ceramic fiber material technology, specifically a ceramic fiber liner raw material hydrolysis device. Background Technology
[0002] Ceramic fiber is a fibrous, lightweight refractory material with advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Colloidal hydrolysis: The preparation of polycrystalline ceramic fibers involves hydrolyzing metal salts (such as AlCl3) in an acidic aqueous solution to generate colloidal hydroxides, forming a viscous precursor solution.
[0003] Chinese utility model patent CN208933391U, published on June 4, 2019, discloses a hydrolysis pot for hemicellulose, comprising a cylinder, a pressure relief device, a circulation pipe, a top cover, a slurry inlet, and a collector for solid-liquid separation. The cylinder has a pressure relief port and a slurry inlet at its upper end. From bottom to top, the pressure relief port is fitted with a sealing gasket, a bushing, and a top cover. The pressure relief device is installed on the top cover. Acid-resistant ceramic tiles are fixed to the inner wall of the cylinder. A collector is installed at the lower part of the cylinder, with a discharge port and a steam inlet on its side. A material outlet is installed at the bottom of the collector. The two ends of the circulation pipe are connected to the discharge port and the slurry inlet via tee fittings, and a circulation pump is installed on the circulation pipe. This utility model achieves uniform hydrolysis of hemicellulose, ensures stable temperature and pressure through the pressure relief device, and, by installing acid-resistant bricks on the inner wall of the cylinder, gives the hydrolysis pot temperature resistance, pressure resistance, and acid resistance, extending its service life.
[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing hydrolysis devices do not have a stirring function for the hydrolyzed mixture, so they cannot achieve uniform and complete dissolution in water for hydrolysis in a short time. At the same time, due to the difference in density, the mixture will separate into upper or lower layers in the water when it is still. Utility Model Content
[0005] The purpose of this invention is to solve the technical problem that existing hydrolysis devices lack a stirring function for the hydrolyzed mixture, thus failing to achieve uniform and thorough dissolution in water for hydrolysis in a short time. Furthermore, due to differences in density, the mixture may separate into upper or lower layers in the water under static conditions. This invention provides a hydrolysis device for ceramic fiber liner raw materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] The present invention discloses a ceramic fiber liner raw material hydrolysis device, comprising a hydrolysis tank for hydrolyzing ceramic fiber raw materials; a drive shaft is rotatably connected in a sealed manner inside the hydrolysis tank; branch pipes are symmetrically fixed to the drive shaft; multiple stirring pipes are pin-connected between the branch pipes; a motor is fixedly connected to one end of the drive shaft; a discharge trough is opened inside the hydrolysis tank; a first insert plate is slidably inserted in the discharge trough; and an extension pipe is fixedly connected to the lower end of the hydrolysis tank in connection with the discharge trough.
[0008] Furthermore, an arc frame is sleeved at the lower end of the hydrolysis tank; multiple support columns are fixedly connected to the lower end face of the arc frame; and a support plate is fixedly connected to the lower end of each support column.
[0009] Furthermore, the support plate is symmetrically provided with ramps; two rollers are provided on the ramps for rolling friction; fixed plates are symmetrically sleeved on the rollers; and a transfer box is fixedly connected between the fixed plates.
[0010] The ceramic fiber liner raw material hydrolysis device provided by this utility model has the following beneficial effects:
[0011] 1. This utility model involves placing ceramic fiber raw materials into a hydrolysis tank for aluminum salt hydrolysis. Then, a motor is powered on to drive the drive shaft and branch pipe to rotate, which in turn drives multiple stirring tubes to rotate and stir the aluminum salt hydrolysate material against the inner wall of the hydrolysis tank. Through stirring, the aluminum salt can fully contact the aqueous solution for hydrolysis. And because multiple stirring tubes are fully in contact with the inner wall of the hydrolysis tank, accumulation and stratification will not occur.
[0012] 2. This utility model allows the first insert plate to be easily moved by holding the first handle with both hands when it is necessary to move the first insert plate to open or close the discharge tank, thereby opening or closing the discharge tank and allowing the mixed liquid after hydrolysis inside the hydrolysis tank to be discharged in a timely manner. Because the motor is located on the side of the hydrolysis tank, it can be completely exposed to the air for passive heat dissipation, so that excessive temperature will not accumulate during long-term operation and cause malfunction.

[0021] Please see Figure 1-3 As shown, a ceramic fiber liner raw material hydrolysis device includes a hydrolysis tank 1 for hydrolyzing ceramic fiber raw materials; a drive shaft 2 is rotatably connected inside the hydrolysis tank 1; branch pipes 4 are symmetrically fixed to the drive shaft 2; multiple stirring pipes 19 are pin-connected between the branch pipes 4; a motor 3 is fixedly connected to one end of the drive shaft 2; a discharge trough 5 is opened inside the hydrolysis tank 1; a first insert plate 6 is slidably inserted into the discharge trough 5; an extension tube 8 is fixedly connected to the lower end of the hydrolysis tank 1 through the discharge trough 5. By placing the ceramic fiber raw material into the hydrolysis tank 1 for aluminum salt hydrolysis, and then energizing the motor 3 to drive the drive shaft 2 and branch pipes 4 to rotate, thereby causing the multiple stirring pipes 19 to rotate and stir the aluminum salt hydrolysate against the inner wall of the hydrolysis tank 1. Through stirring, the aluminum salt can fully contact the aqueous solution for hydrolysis, and because the multiple stirring pipes 19 are fully in contact with the inner wall of the hydrolysis tank 1, no accumulation or stratification will occur.
[0022] Reference Figure 2The lower end of the hydrolysis tank 1 is fitted with an arc frame 11; multiple support columns 12 are fixed to the lower end of the arc frame 11; a support plate 13 is fixed to the lower end of the support column 12. The arc frame 11 supports the hydrolysis tank 1, so that the hydrolysis tank 1 can be stably supported. The support plate 13 has a large contact area with the ground, so that the weight of the hydrolysis tank 1 can be stably supported.
[0023] Reference Figure 2 The support plate 13 is symmetrically provided with ramps 14; two rollers 17 are provided on the ramps 14 for rolling friction; fixed plates 16 are symmetrically sleeved on the rollers 17; a transfer box 15 is fixed between the fixed plates 16. Through the symmetrically provided ramps 14, when the two rollers 17 are symmetrically located on the ramps 14, they can straddle the support plate 13 and will not be easily moved to other positions by external forces, so that they can always be located below the extension tube 8 to receive the discharged hydrolysate.
[0024] Reference Figure 1 The two sides of the transfer box 15 are symmetrically fixed with second handles 18. Two people can easily push and pull the transfer box 15 through the two second handles 18, so that it can be moved and detached from the ramp 14 for transfer.

When the distance of the second insert plate 9 inside the outer tube 8 is moved, a part of the channel of the outer tube 8 can be opened, thereby controlling the speed at which the hydrolysate is discharged from the outer tube 8, which can be adjusted according to the transfer speed of the receiving container.
[0026] Reference Figure 1 The motor 3 is detachably fixed to the side of the hydrolysis tank 1; the end of the first insert plate 6 is fixed with a first handle 7. When it is necessary to move the first insert plate 6 to open or close the discharge tank 5, the first handle 7 can be held with both hands to easily move the distance of the first insert plate 6, thereby opening or closing the discharge tank 5, so that the mixed liquid after hydrolysis inside the hydrolysis tank 1 can be discharged in time; because the motor 3 is located on the side of the hydrolysis tank 1, it can be completely exposed to the air for passive heat dissipation, so that excessive temperature will not accumulate during long-term operation, thus preventing operational failure.
