An arch-bottom end cap, by setting the cross-sectional shape of the end cap body to an arch shape, allows the end cap body to better withstand pressure from all directions, enhancing the structural strength of the end cap. The design of the annular concave portion not only optimizes the hydrodynamic performance of the end cap, reducing fluid eddies and resistance at the end cap, but also improves the overall efficiency of the equipment. The central convex portion further enhances the rigidity of the end cap, enabling it to remain stable under high-pressure environments. Furthermore, the continuous arc surface structure between the annular concave portion and the central convex portion not only makes the end cap more aesthetically pleasing but also improves its corrosion resistance and wear resistance, extending the service life of the equipment. In addition, the discharge port in this design is located on the annular concave portion, allowing materials to flow more smoothly from the inside of the end cap, avoiding material accumulation and blockage at the end cap, further improving the operating efficiency and stability of the equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] This utility model provides the following technical solution:

[0017] As attached Figure 1As shown, this utility model discloses an arch-bottom end cap, including an end cap body 1. The cross-sectional shape of the end cap body 1 is arch-shaped. The end cap body 1 has an annular concave portion 2 and a central convex portion 3 located at the center of the annular concave portion 2. The annular concave portion 2 and the central convex portion 3 are arranged in a continuous arc surface structure. Specifically, in this design, by setting the cross-sectional shape of the end cap body 1 to an arch shape, the end cap body 1 can better withstand pressure from all directions, enhancing the structural strength of the end cap. The design of the annular concave portion 2 not only optimizes the hydrodynamic performance of the end cap, reducing fluid eddies and resistance at the end cap, but also improves the overall efficiency of the equipment. The central convex portion 3 further enhances the rigidity of the end cap, enabling it to remain stable under high pressure. In addition, the continuous arc surface structure between the annular concave portion 2 and the central convex portion 3 not only makes the appearance of the end cap smoother and more aesthetically pleasing, but also improves the corrosion resistance and wear resistance of the end cap, extending the service life of the equipment. Furthermore, in this design, the discharge port is located on the annular concave part 2. This design allows the material to flow out of the head more smoothly, avoiding the accumulation and blockage of material at the head, and further improving the operating efficiency and stability of the equipment.

[0018] Furthermore, the annular concave portion 2 has an outer ring portion 4, a central arc-shaped portion 5, and an inner ring portion 6. The outer ring portion 4 is located on the same elliptical circumference, and the central arc-shaped portion 5 gradually concaves inward from the outer ring portion 4 towards the inner ring portion 6. Specifically, in this embodiment, the design of the outer ring portion 4 enhances the connection strength between the end cap and the external structure, ensuring the stability of the end cap under high-pressure working conditions. The central arc-shaped portion 5 gradually concaves inward from the outer ring portion 4 towards the inner ring portion 6. This design not only further optimizes the fluid flow path and reduces turbulence and energy loss of the fluid inside the end cap, but also improves the energy efficiency of the equipment. The inner ring portion 6 serves as a support point for the internal structure of the end cap, enhancing the overall rigidity of the end cap and making it less prone to deformation under high pressure. In addition, this annular concave portion 2 structure, composed of the outer ring portion 4, the central arc-shaped portion 5, and the inner ring portion 6, makes the end cap easier to form during the manufacturing process, reducing production costs, while improving the precision and durability of the end cap.

[0019] Furthermore, a discharge port (not shown in the figure) is provided on the annular concave portion 2, and the discharge port is located on the central arc-shaped portion 5 of the annular concave portion 2. Specifically, in this embodiment, in order to prevent material accumulation, the discharge port is located on the annular concave portion 2, and the central protruding portion 3 of the annular concave portion 2 guides the material flow to the discharge port, allowing the material to flow out of the end cap more smoothly. The location of the discharge port on the central arc-shaped portion 5 further optimizes the material flow path, reduces the residence time of the material inside the end cap, avoids material accumulation and blockage, and thus improves the operating efficiency and stability of the equipment.

[0020] Furthermore, the vertical distance between the center of the central inner protrusion 3 and the top of the outer ring of the end cap body 1 is 19cm. Specifically, in this embodiment, the vertical distance between the center of the central inner protrusion 3 and the top of the outer ring of the end cap body 1 is 19cm, which ensures the structural stability and rigidity of the end cap under high pressure and also optimizes the flow path of the material.

[0021] Furthermore, the radius of the circumference of the central inner protrusion 3 is 20cm, and the radius of the circumference of the annular inner concave portion 2 is 25cm. Specifically, in this embodiment, the radius of the circumference of the central inner protrusion 3 is 20cm. This design allows the central inner protrusion 3 to better support the internal structure of the end cap, enhancing the overall rigidity of the end cap. Simultaneously, the radius of the circumference of the annular inner concave portion 2 is 25cm. This size selection ensures both the connection strength between the end cap and the external structure and optimizes the fluid flow path, reducing eddies and resistance at the end cap. This dimensional design allows the end cap to remain stable even when subjected to high pressure and high-speed fluid impacts, ensuring the long-term stable operation of the equipment.

[0022] Furthermore, the wall thickness of the end cap body 1 is 1.4 cm. Specifically, in this embodiment, the wall thickness of the end cap body 1 is 1.4 cm, which ensures the structural strength of the end cap while also optimizing the weight of the end cap, making the end cap more convenient to install and transport.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
