[0001] This application belongs to the field of cylindrical end cap technology, specifically relating to a graphite barrel end cap structure. Background Technology

[0002] Traditional head structure forms (such as) Figure 1 When used in silicon steel projects in steel plants, this structural design causes silica sludge to deposit at the bottom of the end caps due to the presence of silica sludge in the material. As the equipment operates for extended periods, the silica sludge accumulates, clogging the graphite pores. Utility Model Content

[0005] Furthermore, the inner groove includes a first conical groove and a second conical groove with different inner wall inclination angles. The first conical groove is located at the bottom of the cylindrical head, and the second conical groove is located between the pipe opening and the first conical groove.

[0006] Furthermore, the inner diameter of the top of the first conical groove is the same as the inner diameter of the bottom of the second conical groove and they are interconnected.

[0007] Furthermore, the inner diameter of the top of the second conical groove is the same as the inner diameter of the bottom of the pipe opening and they are interconnected.

[0008] Furthermore, a connecting flange is provided at the end of the pipe opening.

[0009] Furthermore, an annular plate is provided on the upper side of the outer wall of the cylindrical head, and multiple through holes are provided in the annular plate.

[0010] The beneficial effects of this application are: by replacing the annular central groove in the traditional end cap with a tapering inner groove from the outside in, the degree of silica sludge accumulation is reduced during material flow, thereby increasing the service life of the end cap.

[0013] 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.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] like Figures 1-2 As shown, this application discloses a graphite barrel end cap structure, including: a cylindrical end cap 1, with a pipe opening 2 at the middle of the upper end of the cylindrical end cap 1, and multiple tapering inner grooves on the inner side of the lower end of the cylindrical end cap 1; wherein, the inner grooves are connected to the pipe opening 2. The tapering inner grooves in the above design prevent material from accumulating in the inner grooves during passage, reducing the need for cleaning the end cap and thus improving the service life of the end cap.

[0016] The inner tank includes a first conical groove 3 and a second conical groove 4 with different inner wall inclination angles. The first conical groove 3 is located at the bottom of the cylindrical head 1, and the second conical groove 4 is located between the pipe opening 2 and the first conical groove 3. In the above design, the first conical groove 3 and the second conical groove 4 are set as conical grooves with different inclination angles. In the vertical direction, the inclination angle of the side wall of the second conical groove 4 is greater than that of the side wall of the first conical groove 3, thereby ensuring that the material can be concentrated and discharged at the pipe opening 2 when it passes through. At the same time, the conical grooves can effectively reduce the accumulation of silica sludge in the material. In other embodiments, three or four conical grooves with different inclination angles can also be set in the inner tank, which can be adjusted according to actual needs.

[0017] The inner diameter of the top of the first conical groove 3 is the same as the inner diameter of the bottom of the second conical groove 4 and they are interconnected. In the above design, the inner diameter of the bottom of the first conical groove 3 is larger than the inner diameter of its top and the bottom of the second conical groove 4, so that the first conical groove 3 initially guides the material, and then the second conical groove 4 further concentrates and guides it.

[0018] The inner diameter of the top of the second conical groove 4 is the same as the inner diameter of the bottom of the pipe opening 2 and they are interconnected. In the above design, the inner diameter of the bottom of the second conical groove 4 is larger than the inner diameter of its top and the bottom of the pipe opening 2. The second conical groove 4 guides the material into the pipe opening 2 for discharge.

[0019] The pipe port 2 is provided with a connecting flange 21, which allows the end cap to be connected to an external pipe, thereby facilitating material transfer.

[0020] An annular plate 5 is provided on the upper side of the outer wall of the cylindrical head 1, and the annular plate 5 has multiple through holes 51. The annular plate 5 in the above design is used to connect the flange plate outside the heat exchange cylinder to the head by bolts or other means when the head is installed on the heat exchange cylinder, so that the head can be firmly connected in the heat exchange cylinder. The through holes 51 are used for hinge bolts.

[0021] The specific working principle involves installing the cylindrical end cap 1 onto the end of the graphite heat exchanger cylinder. Simultaneously, the through hole 51 in the annular plate 5 corresponds to the hole in the connecting plate on the outer side of the graphite heat exchanger cylinder. Bolts are then used to securely connect the end cap to the graphite heat exchanger cylinder. Subsequently, the external transport pipe is connected to the connecting flange 21 of the pipe port 2. When material enters the end cap from the graphite heat exchanger tube, it is first guided by the first conical groove 3, and then again by the second conical groove 4, ultimately guiding the material to the pipe port 2. The reduced-shape inner groove can reduce the accumulation of silica sludge during material flow, thereby extending the service life of the end cap.

[0022] 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 transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
