[0002] Alumina fiber is a polycrystalline inorganic fiber whose main component is alumina. Alumina fiber is one of the ultra-lightweight high-temperature thermal insulation materials. It uses the high-tech "sol-gel" method to make soluble aluminum and silicon salts into a colloidal solution with a certain viscosity. The solution is spun into a fiber embryo through high-speed centrifugation, and then is made through dehydration, drying and medium-high temperature heat treatment crystallization.

[0003] Spinning nozzles are key equipment in the mass production of alumina fibers. Currently, integrated spinning nozzles are difficult to manufacture and have a short service life. Furthermore, over extended use, if part of the spinneret of an integrated spinning nozzle becomes damaged, the entire nozzle must be replaced, resulting in waste and high maintenance costs. Therefore, an embedded, segmented fiber spinning nozzle and fiber production equipment are proposed to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, in order to achieve the above purpose, the utility model provides an embedded block fiber spinning nozzle, including: an air inlet plate 1, a liquid inlet plate 3, a liquid outlet plate 2 and an air outlet plate 4.

[0029] Among them, the air inlet plate 1 adopts an integrated design to increase the assembly accuracy of the spinning nozzle, while improving the uniformity of the air intake, thereby improving the quality of the finished fiber. A number of liquid outlet plates 2 are arranged in an array on the upper surface of the air inlet plate 1, and a liquid inlet plate 3 is set on the top surface of the liquid outlet plate 2. Each liquid inlet plate 3 is connected to a liquid outlet plate 2. Specifically, the bottom surface of the liquid inlet plate 3 abuts the top surface of the liquid outlet plate 2, and the colloidal solution is provided to the liquid outlet plate 2 through the liquid inlet plate 3. In addition, a number of spinnerets 201 are evenly spaced at the lower end of the liquid outlet plate 2, and the colloidal solution is sprayed out through the spinneret 201.

[0030] like Figure 3 As shown, it should be noted that an air outlet plate 4 is provided at the lower end of the liquid outlet plate 2, and an air outlet hole 5 is provided on the top surface of the air outlet plate 4. The air outlet hole 5 is used to accommodate the lower end of the liquid outlet plate 2, that is, the air outlet hole 5 is provided on the circumferential outside of the lower end of the liquid outlet plate 2, and the liquid outlet plate 2 is set as a separate module in the air inlet plate 1. When the liquid outlet plate 2 is damaged, the liquid outlet plate 2 can be replaced separately without disassembling the air inlet plate 1 which is more difficult to process, thereby improving the service life of the spinning nozzle.

[0031] In addition, a clearance is reserved between the air outlet 5 and the lower end of the liquid outlet plate 2, meaning that the air outlet 5 and the lower end of the liquid outlet plate 2 do not contact each other. Preferably, the air outlet plate 4 is fixed to the bottom surface of the air inlet plate 1 with screws, so that the top surface of the air outlet plate 4 abuts the bottom surface of the air inlet plate 1. If the air outlet plate 4 is damaged, it can be replaced by removing the screws, making maintenance convenient. Furthermore, replacing the air outlet plate 4 individually reduces waste of the spinning nozzle and effectively lowers maintenance costs.

[0032] It should be noted that during the use of a spinning nozzle, the liquid outlet portion is the most susceptible to wear, while the air inlet portion is less susceptible to damage. Specifically, the portions of the liquid outlet plate 2 are susceptible to wear and damage, which can affect the nozzle's service life. In the production of a spinning nozzle, the air inlet plate 1 is the most difficult to machine, while the liquid outlet plate 2 is relatively easy to machine. Therefore, the air inlet plate 1, liquid inlet plate 3, air outlet plate 4, and liquid outlet plate 2 are manufactured separately and then assembled. Later in use, damaged portions can be replaced based on usage, thereby reducing waste and lowering maintenance costs.

[0033] like Figure 4As shown, a plurality of first air inlet holes 101 are arranged in an array on the top surface of the air inlet plate 1. Specifically, assembly grooves 9 are symmetrically provided on both sides of the air inlet plate 1. The assembly grooves 9 are used to penetrate the air inlet pipe, which is connected to the first air inlet hole 101. High-speed airflow is transported into the air inlet hole through the air inlet pipe. At the same time, a plurality of blowing holes (not shown in the figure) are provided on the bottom surface of the air inlet plate 1, wherein the blowing holes are arranged in a linear array directly above the exhaust gap, and each blowing hole is connected to the first air inlet hole 101. High-speed airflow is blown into the exhaust gap through the air inlet plate 1, and the high-speed airflow passes through the exhaust gap to reach the position of each spinneret 201, thereby forming a softer, continuous and stable traction force on the colloidal solution at the position of the spinneret 201, and blowing the fiber colloid into fibers with a finer diameter and a smoother surface, so as to improve the quality of the finished fiber.

[0034] In one embodiment of the present invention, a plurality of second air inlet holes 102 are arranged in an array on the side of the air inlet plate 1. Specifically, the second air inlet holes 102 are symmetrically arranged on the two side surfaces of the air inlet plate 1 at equal intervals. At the same time, a second air inlet hole 102 is provided on both sides of each exhaust gap. The second air inlet hole 102 is connected to the blowing hole. A high-speed air flow is blown simultaneously through the second air inlet hole 102 and the first air inlet hole 101, so that the air pressure of the high-speed air flow is the same when it reaches the position of each blowing hole, and then the high-speed air flow is evenly blown to each position in the exhaust gap through the blowing hole, ensuring that the flow rate of the high-speed air flow at each position of the spinning nozzle is kept as consistent as possible, thereby further improving the quality of the finished fiber.

[0035] It should be noted that first inclined surfaces 203 are symmetrically provided on both sides of the lower end of the liquid outlet plate 2, that is, the cross-section of the lower end of the liquid outlet plate 2 is cone-shaped as a whole, and the tip of the cross-section of the lower end of the liquid outlet plate 2 faces the air outlet 5, and the two side surfaces of the air outlet 5 are provided as second inclined surfaces, that is, the cross-section of the air outlet 5 is cone-shaped as a whole, and is adapted to the lower end of the liquid outlet plate 2. In this case, the gap between the first inclined surface 203 and the second inclined surface is an exhaust gap. Preferably, the first inclined surface 203 and the second inclined surface located on the same side of the liquid inlet plate 3 are parallel to each other, and the vertical distance between the first inclined surface 203 and the second inclined surface located on the same side of the liquid inlet plate 3 is equal at all positions, so as to ensure that when the colloidal solution is ejected from the spinneret 201 at each position of the lower end of the liquid outlet plate 2, the surrounding high-speed airflow speed is consistent, and the colloidal solution ejected from each spinneret 201 has the same shape and size, thereby improving the qualified rate of the finished fiber.

[0036] In one embodiment of the present invention, a plurality of assembly holes 6 are arranged in an array on the surface of the air inlet plate 1, and each assembly hole 6 is embedded with a liquid outlet plate 2, wherein a card groove is provided on the circumferential side surface of the upper end portion of the liquid outlet plate 2, and the outer circumferential side surface of the card groove abuts against the inner circumferential side surface of the assembly hole 6, ensuring that the liquid outlet plate 2 is tightly fixed on the air inlet plate 1.

[0037] In addition, a stepped groove 7 is provided on the top surface of the assembly hole 6, and a limiting plate 202 is provided on the top surface of the liquid outlet plate 2. The limiting plate 202 is snap-connected to the stepped groove 7. When the upper end of the liquid outlet plate 2 is fixed in the assembly hole 6, the circumferential edge of the bottom surface of the limiting plate 202 abuts the stepped groove 7.

[0038] Preferably, the limiting plate 202 is connected to the stepped groove 7 by a number of screws. Specifically, a plurality of connection holes are set on the surface of the limiting plate 202, and a plurality of through holes are set on the top surface of the limiting plate 202. After the upper end portion of the liquid outlet plate 2 is fixed in the assembly hole 6, the limiting plate 202 is fixed to the upper end surface of the liquid outlet plate 2 by screws passing through the through holes and threadedly connecting the connection holes. At this time, the position of the liquid outlet plate 2 on the air inlet plate 1 is locked.

[0039] In one embodiment of the present invention, a first liquid inlet hole 8 is provided on the top surface of the liquid inlet plate 3, and a second liquid inlet hole (not shown in the figure) is provided on the top surface of the liquid outlet plate 2. When the liquid inlet plate 3 is docked with the liquid outlet plate 2, the first liquid inlet hole 8 is sealed and connected to the second liquid inlet hole to ensure that the liquid can be stably input into the liquid outlet plate 2 and stably ejected from the spinneret 201.

[0040] Optionally, a storage chamber of a certain volume is provided inside the liquid outlet plate 2, and the colloidal solution entering from the liquid inlet plate 3 into the liquid outlet plate 2 is stored in the storage chamber. When the colloidal solution in the storage chamber reaches a certain amount and the pressure value reaches a certain level, the colloidal solution is uniformly sprayed out from each spinneret 201, avoiding the phenomenon of inconsistent colloidal solutions sprayed from different spinnerets 201, and preventing the sprayed colloidal solution from being disconnected, thereby ensuring the quality of the finished fiber.

[0041] Optionally, a tubular groove is provided at the upper end of the first liquid inlet hole 8, and a tubular protrusion is provided at the upper end of the second liquid inlet hole. After the liquid inlet plate 3 is docked with the liquid outlet plate 2, the first liquid inlet hole 8 and the second liquid inlet hole can fit tightly together to prevent leakage of the colloidal solvent. At the same time, a sealing gasket is provided between the tubular groove and the tubular protrusion. The sealing gasket further strengthens the connection tightness between the first liquid inlet hole 8 and the second liquid inlet hole, further prevents leakage of the colloidal solvent, and improves the quality of the finished fiber.

[0042] In one embodiment of the present invention, the surface of the air inlet plate 1 is provided with a plurality of screw holes 10 arranged in an array, which are threadedly connected to countersunk screws. Simultaneously, the surface of the liquid inlet plate 3 is provided with a plurality of mating holes 11 arranged in an array, which are used to pass countersunk screws. The countersunk screws pass through the mating holes 11 to secure the liquid inlet plate 3 to the top surface of the air inlet plate 1. At this point, the bottom surface of the liquid inlet plate 3 is pressed against the top surface of the liquid outlet plate 2, and the first liquid inlet hole 8 and the second liquid inlet hole are butted together, completing the assembly of the liquid inlet plate 3.

[0043] When the present invention is in use, the liquid outlet plate 2 is installed in the assembly hole 6, and the countersunk screw is passed through the matching hole 11 to fix the liquid inlet plate 3 on the top surface of the air inlet plate 1, and the liquid inlet plate 3 is pressed against the liquid outlet plate 2 to fix the air outlet plate 4 on the bottom surface of the air inlet plate 1. The air outlet hole 5 is arranged on the circumferential outside of the lower end of the liquid outlet plate 2, and the colloidal solution passes through the first liquid inlet hole 8 and the second liquid inlet hole in the liquid inlet plate 3 in turn into the liquid outlet plate 2 and is evenly sprayed out from each spinneret 201. At the same time, the high-speed airflow passes through the first air inlet hole 101 and the second air inlet hole 102 blowing holes in turn and is blown toward the exhaust gap through the blowing holes, and reaches the position of each spinneret 201 through the exhaust gap, forming a softer, continuous and stable traction force on the colloidal solution at the position of the spinneret 201, so that the fiber colloid is sprayed out from the spinneret 201 at a uniform speed.

[0044] In summary, the liquid outlet plate 2 is set as a separate module in the air inlet plate 1. When the liquid outlet plate 2 is damaged, the liquid outlet plate 2 can be replaced separately, thereby improving the service life of the spinning nozzle, and there is no need to disassemble the air inlet plate 1 which is more difficult to process, reducing the waste of the spinning nozzle and effectively reducing maintenance costs.

[0046] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0047] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
