Description

Technical Field

[0001] This utility model relates to the technical field of basalt fiber preparation equipment, and in particular to a cooling support structure for a basalt fiber melting furnace baffle. Background Technology

[0002] Basalt fiber is an inorganic fiber material made from natural basalt ore through high-temperature melting and then drawing. Due to its excellent performance in terms of strength, high temperature resistance, and corrosion resistance, it is widely used in various fields (such as aerospace, construction, automobiles, environmental protection, etc.).

[0003] In the production of basalt fiber, the requirements for basalt fiber production are constantly increasing with the development of the manufacturing process. For example, increasing the drawing temperature of basalt fiber and increasing the number of perforations will subject the existing sprue to greater thermal and mechanical stress, which will cause the sprue to deform. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cooling support structure for the basalt fiber furnace sprue.

[0005] It should be noted that technicians have discovered that as the basalt production process continues to improve, the stencil at the wire drawing point will deform, which will not only affect the service life of the stencil but also seriously affect the stability of wire drawing (and of course, production efficiency).

[0006] The purpose of this utility model is achieved through the following technical solution: a cooling support structure for a basalt fiber melting furnace sprue plate, wherein a sprue plate is fixed at the bottom of the basalt fiber melting furnace, and the sprue plate has leakage holes, through which the molten basalt in the basalt fiber melting furnace flows out and cools to form fibers. Includes cooling components, top support components, and height adjustment components; The cooling assembly is positioned below the perforated plate, and has vertical cooling channels through which fibers pass. The upper support member can be adjusted in position on the cooling assembly in the horizontal plane, and the upper support member abuts against the sump plate. The cooling assembly is fixedly installed by the height adjustment component. Once the cooling components are fixedly installed, the upper support can rest against the bottom surface of the sluice plate, forming a structure to prevent the sluice plate from deforming under high temperatures; when the upper support is adjusted in the horizontal plane, it forms a support structure for the deformed parts of the sluice plate; the adjustment of the height adjustment component can form an adjustment structure for the degree of support of the upper support for the sluice plate.

[0007] As a preferred technical solution of this application, the cooling assembly includes a crossbeam and cooling plates. Cooling water channels are formed on the crossbeam. Two crossbeams are arranged parallel to each other, with multiple cooling plates positioned between them. The cooling plates are spaced apart and their surfaces are vertical, forming a vertically penetrating cooling channel between adjacent cooling plates. Multiple auxiliary plates are welded and fixed to the crossbeam. The auxiliary plates are spaced apart and their surfaces are vertical. The two ends of the cooling plates are bolted to the auxiliary plates, forming a structure that facilitates the replacement of cooling plates of different heights.

[0008] Furthermore, the upper support is a ceramic strip with a long groove extending through both ends on its bottom surface. The ceramic strip is placed on the upper edge of the cooling plate through the long groove, forming a structure in which the upper support can be adjusted in horizontal position.

[0009] As a preferred technical solution of this application, the height adjustment component includes an extension part, a hook part, and a fixing part. The fixing part has a beam rod, and the upper end of the hook part has a hook that hangs on the beam rod. The hook part has an elongated hole, and an adjusting screw is threaded onto the hook part. The extension part is fixed at each of the four corner positions of the cooling component. The extension part has an extension tube that passes through the elongated hole, and the adjusting screw abuts against the lower surface of the extension tube. Rotating the adjusting screw can adjust the upper and lower ends of the extension tube, thereby forming a height adjustment structure.

[0010] Furthermore, the extension includes an extension tube and an ear plate A; one end of the extension tube is fixed to the ear plate A, and the ear plate A is fixed to the cooling assembly by bolts; the cooling assembly has a cooling water channel, and the extension tube is connected to the cooling water channel, serving as a water pipe for water inlet and outlet.

[0011] Furthermore, the hook portion includes an ear plate C, a nut, and an adjusting screw; Two ear plates C are arranged opposite each other, and a nut is welded and fixed between their lower ends. An adjusting screw is screwed onto the nut from bottom to top. The upper end of the ear plate C is a hook, and an elongated hole is opened on the ear plate C.

[0012] Furthermore, the fixing part includes a beam and ear plates C. Ear plates C are welded and fixed at both ends of the beam and fixed to the roof base beam frame.

[0013] To facilitate understanding, the working principle and core innovations of this invention will be explained as follows: I. In existing related technologies, the corresponding equipment structure for the preparation of basalt fibers is as follows: a basalt fiber melting furnace (with a perforated plate at the bottom) is provided, a cooling assembly is installed below the furnace, and a drawing and collecting furnace is installed below the cooling assembly. The fiber preparation process is as follows: basalt raw material is poured into the melting furnace and heated. After the basalt is melted into a liquid, it flows down from the perforation of the perforated plate (forming individual filaments). The basalt filaments are cooled and shaped by the cooling assembly to form long fibers. These fibers are then bundled by a bundling wheel and subsequently processed (e.g., softening, oil impregnation, etc.).

[0014] The problem is that, with increasing demands for production efficiency, some companies have increased the furnace temperature and the number of holes in the perforated plate. This allows basalt to melt faster and produces more filaments, thus improving efficiency. However, current perforated plates are made of ordinary steel, and if the furnace temperature is too high or the number of holes increases, the perforated plate is prone to deformation during operation (the inventors discovered that this deformation affects the quality of the fibers). An obvious solution is to use special high-temperature resistant materials to manufacture the perforated plate, but this inevitably increases costs (these high-temperature resistant materials are expensive).

[0015] Second, this solution uses a specific structural design to provide support for the sprue plate, thereby preventing deformation of the sprue plate; while ensuring production efficiency (meeting the requirements of high furnace temperature and a large number of sprue holes) and low cost, a structure is designed to prevent deformation of the sprue plate. Specifically, in this solution: (1) a. An upper support is provided on the cooling assembly to support the leak edge and prevent deformation of the leak plate; b. The upper support is set on the cooling assembly in an adjustable horizontal position, and the position of the upper support is adjusted to support the deformed part of the leak plate; c. The cooling assembly is fixedly installed by a height adjustment assembly, and the height of the cooling assembly is adjusted by the height adjustment assembly, thereby adjusting the height position of the upper support, so as to achieve different degrees of upper support for the deformed part of the leak plate; (2) The cooling assembly can be lowered to a certain height by the height adjustment assembly, so as to facilitate the replacement of upper supports of different heights and lengths. Support; (3) In the height adjustment assembly, the cooling assembly is installed on the hook part with adjustable height via the extension part. The hook part is suspended on the fixed part by the hook style. This suspension method makes it easy to remove the cooling assembly and to easily replace different models of top support parts (depending on the size of the area of ​​the deformation of the sprue plate and the amount of deformation, the corresponding length of the top support part can be replaced and more top support parts can be installed), thus making it easy to replace various parts (especially to install more top support parts); (4) The top support part is made of ceramic strips, which can withstand high temperature and have high hardness; (5) The structure of the cooling assembly and the structure of the height adjustment assembly make it easy to disassemble and replace the corresponding parts.

[0016] This invention has the following advantages: through a low-cost structure, it avoids excessive deformation of the basalt fiber caused by the high temperature of the furnace and the large number of holes in the basalt fiber, thereby ensuring the production quality of basalt fiber; in layman's terms, under the process requirement of improving production efficiency, the production quality of basalt fiber is guaranteed through a low-cost structure.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0019] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this utility model is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] It should be noted that in existing related technologies, the preparation of basalt fibers typically involves a basalt fiber melting furnace (with a perforated plate at the bottom), a cooling assembly below the furnace, and a drawing and sizing furnace below the cooling assembly. The production process of basalt fibers involves pouring basalt raw material into the furnace for heating. After the basalt is melted into a liquid, it flows down through the perforations of the perforated plate (forming individual filaments). The basalt filaments are then cooled and shaped by the cooling assembly into long fibers. These fibers are then bundled by a bundling wheel and subsequently processed (e.g., softening, oil impregnation, etc.).

[0021] The problem is that with changes in the production process (to improve work efficiency) – requiring higher temperatures in the furnace (to increase melting speed) and an increase in the number of holes in the spinneret (to increase the density of holes) – the spinneret becomes very prone to deformation. The inventors discovered that when the spinneret deforms, it affects the quality of the produced fibers.

[0022] Therefore, this solution offers the following approach: a. By designing a ceramic support between the perforator and the cooling assembly, the perforator is prevented from deforming; b. Furthermore, the ceramic support can be adjusted horizontally and vertically to accommodate the location and degree of perforation; c. This design ensures fiber production quality even with higher furnace temperatures and denser perforations in the perforator, while also saving costs (an easy approach would be to use a perforator made of a better material, but such a perforator is extremely expensive).

[0023] The following specific embodiments will further illustrate the concept of this solution (it should be noted that, without conflict, the embodiments and features and technical solutions in this utility model can be combined with each other).

[0024] See Figures 1-3 As shown, this embodiment provides a cooling support structure for a basalt fiber furnace sluice plate. A sluice plate 1 is fixed at the bottom of the basalt fiber furnace, and the sluice plate 1 has sluice holes. A cooling assembly 10 is provided below the sprue plate 1, and the cooling assembly 10 has an upper and lower through cooling channel for fibers to pass through; an upper support member 20 that can be adjusted in position on the horizontal plane is provided on the cooling assembly 10, and the upper support member 20 abuts against the sprue plate 1; in addition, the cooling assembly 10 is also fixedly installed by a height adjustment assembly 30. During the fiber preparation process, basalt is melted into liquid in a basalt fiber furnace, and then falls into the perforation of the perforator plate 1 to form filaments. These filaments pass through the cooling channels above and below the cooling assembly 10 for cooling. During the fiber preparation process, the high temperature inside the basalt fiber furnace and the numerous perforations on the spinneret (higher temperature and denser perforations compared to traditional furnaces) make the spinneret prone to deformation. In this solution, an upward force is applied to the spinneret by the upper support member 30 to prevent deformation. In addition, the upper support member 30 is positioned against the deformed area of ​​the spinneret by horizontal adjustment, and the degree of upward push of the upper support member 30 is adjusted by height adjustment (to accommodate different degrees of deformation of the spinneret).

[0025] The structure of the cooling assembly 10 will be further explained below.

[0026] See Figure 1 , Figure 2 and Figure 4 The cooling assembly 10 includes two crossbeams 11 and multiple cooling plates 12. The crossbeams 11 are flat beams and have cooling water channels that extend through both ends. The two crossbeams 11 are placed in a horizontal plane and are parallel to each other. Multiple cooling plates 12 are placed between the two crossbeams 11. The cooling plates 12 are parallel to each other and spaced apart. The surface of the cooling plates 12 is located in a vertical plane, so that a vertical cooling channel is formed between adjacent cooling plates 12.

[0027] It should be noted that in the cooling assembly 10, the cooling water channel on the crossbeam 11 is circulatedly connected to the corresponding cold water circulation mechanism (for example, a pipe is connected to the cooling water channel, a pump is installed on the pipe, and the pipe is also connected to the cooler, thus forming a circulation). During operation, the wire flowing out from the hole of the sprue plate 1 passes through the cooling channel between the two cooling plates 12, and is cooled by the low temperature formed by the two cooling plates 12.

[0028] Furthermore, in this plan, see [reference]. Figure 4 Multiple auxiliary plates 13 are welded and fixed to the crossbeam 11. These auxiliary plates 13 are arranged parallel to each other and spaced apart, and are also located in a vertical plane. When the ends of the cooling plate 12 are placed on the corresponding crossbeam 11, the cooling plate 12 is fixed to the auxiliary plate 13 with bolts, forming a structure that is easy to disassemble. When the wire flowing from the drain hole of the drain plate 1 needs better cooling or a reduced cooling level, simply replace the cooling plate 12 with one of different heights; this is very simple and convenient.

[0029] The structure of the top support member 20 will be further explained below.

[0030] See Figure 1 and Figure 2 The upper support member 20 is a ceramic strip with a long groove running through both ends on its bottom surface. The ceramic strip is placed on the upper edge of the cooling plate 12 through the groove. If the sluice plate 1 deforms at a certain position, the upper support member 20 will be pushed to that position.

[0031] It should be noted that since the upper support member 20 itself has a certain length, if the sluice plate 1 is deformed at a certain position, it is only necessary to let the corresponding upper support member 20 abut against that position and extend both ends out of that position (in layman's terms, for example, if the deformed position is a circular area, it is only necessary for the upper support member 20 to support the circular area radially and extend both ends out of the circular area, rather than supporting the entire circular area upward).

[0032] The structure of the height adjustment component 30 will be further explained below.

[0033] See Figure 3 The height adjustment component 30 includes an extension 40, a hook 50, and a fixing part 60; The fixing part 60 has a beam 61 (the beam 61 is fixed to the base beam frame of the roof by auxiliary structural members). The hook part 50 has a hook at the upper end, and an elongated hole 5001 is opened on the hook part 50. In addition, an adjusting screw 51 is screwed onto the hook part 50. Among them, an extension 40 is fixed at each of the four corners of the cooling assembly 10, and the extension 40 has an extension tube 41. During installation, the fixing part 60 is fixed to the base beam frame of the roof by means of auxiliary structural members, and the hook part 50 is hung on the beam 61 of the fixing part 60; the extension tube 41 on the extension part 40 is passed through the elongated hole 5001 of the hook part 50, and the upper end of the adjusting screw 51 is pressed against the lower surface of the extension tube 41.

[0034] It should be noted that when it is necessary to adjust the support of the upper support member 20 on the sprue plate (i.e., adjust the vertical height position of the upper support member 20): by rotating the adjusting screw 51, the extension tube 41 moves up and down in the elongated hole 5001, thereby realizing the vertical position adjustment of the extension tube 41, and thus realizing the vertical position adjustment of the cooling assembly 10, thereby realizing the vertical position adjustment of the upper support member 20.

[0035] The structure of the extension 40 will be further explained below.

[0036] Specifically, see Figure 5 The extension 40 includes an extension tube 41 and an ear plate A42; one end of the extension tube 41 is fixed to the ear plate A42, and the ear plate A42 is fixed to the cooling assembly 10 by bolts; the cooling assembly 10 has a cooling water channel, and the extension tube 41 is connected to the cooling water channel, serving as a water pipe for water inlet and outlet.

[0037] The structure of the hook part 50 will be further explained below.

[0038] See Figure 6 The hook part 50 includes an ear plate C53, a nut 52, and an adjusting screw 51; wherein, the two ear plates C53 are arranged opposite each other, and the nut 52 is welded and fixed between the lower ends of the two, and the adjusting screw 51 is screwed onto the nut 52 from bottom to top; the upper end of the ear plate C53 is a hook, and the ear plate C53 has an elongated hole 5001.

[0039] Furthermore, the structure of the fixing part 60 will be explained. (See reference...) Figure 7 The fixing part 60 includes a beam 61 and an ear plate D62. The two ends of the beam 61 are welded and fixed with ear plates D62, which are fixed to the roof base beam frame.

[0040] The above embodiments only illustrate preferred implementation methods, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
