Description

Technical Field

[0001] This application belongs to the field of graphite pipe technology, specifically relating to a layered graphite synthesis furnace nozzle. Background Technology

[0002] A graphite synthesis furnace is a device used for chemical reactions under high temperature and high pressure, primarily for synthesizing various chemical substances. Its structure mainly consists of a furnace body, heating system, pressure system, reaction chamber, and gas inlet / outlet.

[0003] The furnace body is the main part of the graphite synthesis furnace and is usually made of graphite. Graphite has characteristics such as high-temperature corrosion resistance and good thermal conductivity, enabling it to withstand chemical reactions under high temperature and pressure. The graphite furnace liner is one of the main components of the furnace body. It is typically made of thick graphite material and encloses the reaction chamber, capable of withstanding chemical reactions under high temperature and pressure. Due to graphite's high-temperature corrosion resistance and good thermal conductivity, the graphite furnace liner ensures the reaction proceeds smoothly at high temperatures while also providing good insulation to reduce heat loss.

[0004] However, the graphite synthesis furnace needs to be connected to external materials and water pipes through pipes. In order to seal the moisture and materials in the pipes, the pipes will bear the total weight of the pipes themselves plus the external pipes and materials. Over time, this will cause cracks to appear between some pipes and the tower body, or cause cracks to appear in the material pipes themselves. Sometimes, the pipes will even break off completely from the tower wall. Utility Model Content

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is: a layered graphite synthesis furnace nozzle, comprising: a cylinder and a material pipe assembly; the material pipe assembly includes an outer sleeve and an inner sleeve, the inner sleeve being longer than the outer sleeve and passing through the side wall of the cylinder; the outer sleeve is sleeved on the outside of the inner sleeve and fixedly connected to the cylinder; wherein, a plurality of coaxially arranged flanges are sleeved on the outer wall of the inner sleeve.

[0007] Furthermore, a limiting ring block is provided on the side of the inner sleeve away from the cylinder, and the cross-section of the limiting ring block is trapezoidal.

[0008] Furthermore, the first flange and the second flange are connected by the first bolt and the spaced through holes; the second flange and the third flange are connected by the second bolt and the remaining through holes.

[0009] Furthermore, the first flange and the second flange are connected by the first bolt and the spaced through holes; the second flange and the third flange are connected by the second bolt and the remaining through holes.

[0010] Furthermore, one side of the first flange is connected to the end of the outer sleeve.

[0011] Furthermore, two elastic gaskets are provided between the first flange and the second flange.

[0012] Furthermore, the outer edge of the inner ring of the third flange is provided with multiple external through holes.

[0013] The beneficial effects of this application are: this application has an outer sleeve connected to the cylinder on the outside of the traditional straight-through connecting pipe, which enhances the overall strength of the material pipe through the double-layer pipe structure, and the first flange, second flange and third flange are fastened to each other with bolts, which can effectively distribute the external force and prevent the material pipe itself from cracking, thereby reducing maintenance costs.

[0017] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this application provides a layered graphite synthesis furnace nozzle, including: a cylinder 1 and a material pipe assembly; the material pipe assembly includes an outer sleeve 2 and an inner sleeve 3, the inner sleeve 3 being longer than the outer sleeve 2 and passing through the side wall of the cylinder 1; the outer sleeve 2 is sleeved on the outside of the inner sleeve 3 and fixedly connected to the cylinder 1; wherein, multiple coaxially arranged flanges are sleeved on the outer wall of the inner sleeve 3. The outer sleeve 2 and inner sleeve 3 in the above design form a double-layer pipe structure, which can greatly enhance the overall connection strength of the material pipe. At the same time, the flanges are steel flanges, which can be connected to the flanges of external pipes through multiple long bolts, thereby distributing the overall weight of the pipe assembly through the bolts and preventing pipe breakage.

[0019] A limiting ring block 31 is provided on the side of the inner sleeve 3 away from the cylinder 1. The cross-section of the limiting ring block 31 is trapezoidal. In the above design, the length of the inner sleeve 3 is greater than that of the outer sleeve 2. Therefore, the limiting ring block 31 is located on the side of the inner sleeve 3 away from the outer sleeve 2 to determine the installation position of the flange.

[0020] The flange includes a first flange 4 located inside the inner sleeve 3 and a second flange 5 located inside the limiting ring block 31. The external pipe with a third flange 6 is connected to the limiting ring block 31. Each of the first flange 4, second flange 5, and third flange 6 has multiple corresponding through holes 7 along its edges. All three flanges in the above design can be made of steel to support the weight of the pipe.

[0021] The first flange 4 and the second flange 5 are connected by a first bolt 51 and spaced through holes 7; the second flange 5 and the third flange 6 are connected by a second bolt 52 and the remaining through holes 7. This design, with the first bolt 51 passing through the spaced through holes 7 to connect the first flange 4 and the second flange 5, ensures that the inner sleeve 3 shares the stress through the first flange 4 and the second flange 5; the second bolt 52 connects the second flange 5 and the third flange 6 through the remaining through holes 7, thus ensuring a stable connection between the second flange 5 and the third flange 6 of the external pipeline, distributing the overall weight of the pipeline and materials to each flange, thereby preventing pipeline assembly breakage. In other embodiments, the outer diameters of the first flange 4 and the second flange 5 may be larger than that of the third flange 6, and the second flange 5 has two rings of through holes 7 so that the first bolts 51 on the outer rings of the first flange 4 and the second flange 5 are connected, while the second flange 5 and the third flange 6 are connected by the second bolts 52 on the inner rings.

[0022] One side of the first flange 4 is connected to the end of the outer sleeve 2. In the above design, the connection between the first flange 4 and the outer sleeve 2 distributes the stress on the first flange 4 to the outer sleeve 2, thereby further reducing the risk of breakage of the inner sleeve 3.

[0023] Two elastic gaskets 8 are provided between the first flange 4 and the second flange 5. The elastic gaskets 8 in the above design can ensure that the first flange 4 and the second flange 5 have a certain distance, and the connection strength of this section of pipeline is guaranteed by connecting the first flange 4 and the second flange 5.

[0024] The third flange 6 has multiple external through holes 61 on the outer edge of the inner ring. These external through holes 61 can connect to the flange of the external pipeline from the inside, thereby further improving the connection strength of the material pipeline.

[0025] In specific usage, the through holes 7 of the external pipe flange are set to correspond to the through holes 7 of the first flange 4, the second flange 5, and the third flange 6. The first flange 4 and the second flange 5 are connected to the spaced through holes 7 by the first bolt 51, thereby distributing the weight of the inner sleeve 3 to the outer sleeve 2. Then, the second flange 5 and the third flange 6 of the external pipe are connected by the second bolt 52, so that the second flange 5 is connected to the first flange 4 and the third flange 6 respectively. This distributes part of the weight of the inner sleeve 3 and the external pipe to the outer sleeve 2 through the flanges, thereby strengthening the overall connection strength of the material connection pipe, preventing the material connection pipe itself from cracking, and thus reducing maintenance costs.

[0026] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural modifications made based on the description and drawings of this application, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
