[0002] When transporting slurry, an L-shaped pipe is usually used to complete the reversing transportation of the slurry. However, the feeding and discharging of the L-shaped pipe are not particularly smooth. Especially at the bends of the L-shaped pipe, the slurry flow rate is high and the wear is severe. It is easy to leak and has a short service life. After damage, the entire pipe needs to be replaced.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

[0027] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] Example 1, please refer to the attached manual Figure 1-3 The utility model provides a technical solution: a spherical elbow, including a spherical head 1, which is used as a reversing piece in the material conveying process to change the direction of material conveying. Since the spherical head 1 is a spherical structure, when the material enters the spherical head 1, the feeding and discharging are smoother, and the impact of the material is effectively reduced through the buffering of the spherical arc surface, so that the inner wall of the spherical head 1 has a lower wear degree and a longer service life.

[0030] At the same time, the spherical head 1 is made of a hard stainless steel shell structure or other hard structures, and the inner wall of the spherical head 1 is coated with polyurethane, which can further increase the wear resistance of the spherical head 1 and increase the acid and alkali resistance of the spherical head 1.

[0031] A feed pipe 5 for feeding materials and a discharge pipe 6 for discharging materials are provided on the spherical head 1. The feed pipe 5 and the discharge pipe 6 are perpendicular to each other and are both connected to the inside of the spherical head 1. The material enters the spherical head 1 through the feed pipe 5 and is discharged from the discharge pipe 6, thereby changing the conveying direction of the material.

[0032] In order to further reduce the cost of use and maintenance, a connecting flange 7 for connecting to an external pipeline is fixedly provided at the end of the feed pipe 5 and the discharge pipe 6 away from the spherical head 1, so that the spherical head 1 can be replaced separately when it is damaged, which not only facilitates the installation of the spherical head 1 but also reduces the cost of use and maintenance.

[0033] It should be noted that the inner diameter of the spherical head 1 is larger than the inner diameters of the feed pipe 5 and the discharge pipe 6; in this way, when the material enters the spherical head 1 from the feed pipe 5, it enters the large diameter space from the small diameter space, so that the material is further dispersed, which can effectively reduce the impact force when the material enters the spherical head 1; and because the material is continuously conveyed, the rear material will push the front material to be continuously discharged from the discharge pipe 6, so that the material is not easy to accumulate and clog on the arc-shaped structure wall at the bottom of the spherical head 1.

[0034] The spherical head 1 in the utility model is applied to the feeder 4, and can also be applied to other mechanical equipment or material transportation fields, which are not limited here; when the spherical head 1 is applied to the feeder 4, it is used for slurry transportation, and a vertical jet tube 2 and a horizontal jet tube 3 are also provided in the feeder 4, and the vertical jet tube 2 and the horizontal jet tube 3 are respectively connected to the feed pipe 5 and the discharge pipe 6, and the slurry enters from the end of the vertical jet tube 2 and is discharged from the horizontal jet tube 3.

[0035] According to actual needs, multiple spherical heads 1 are provided. In this embodiment, eight spherical heads 1 are provided, which can evenly feed the slurry into the bottom of the feeder 4.

[0036] The spherical head 1 can be produced in batches. First, a spherical shell with openings on both sides is cast, and then a feed pipe 5 and a discharge pipe 6 are welded at the openings on both sides respectively. After that, a connecting flange 7 is welded and fixed at the ends of the feed pipe 5 and the discharge pipe 6. The production is simple and can be mass-produced.

[0037] Example 2, please refer to the attached manual Figure 4 The utility model provides a technical solution: a spherical elbow, the spherical head 1 is a soft shell structure and can be made of materials such as rubber, so that when the material enters the spherical head 1, the elastic deformation ability of the spherical head 1 itself can be used to achieve a good buffer, further reducing the impact of the material on the inner wall of the spherical head 1.

[0038] Furthermore, based on the fact that the spherical head 1 is set as a soft shell structure, it is also convenient to clear the blockage of materials in the spherical head 1. It is only necessary to pinch the spherical head 1 so that the internal space of the spherical head 1 is compressed, thereby squeezing the material out of the spherical head 1 to achieve the purpose of clearing the blockage.

[0039] Taking into account that the spherical head 1 in the utility model is arranged in the feeder 4, it is inconvenient to manually pinch the spherical head 1 to achieve the purpose of unblocking the material. Therefore, an electric push rod 8 is installed on the inner wall of the feeder 4. The electric push rod 8 is horizontally arranged, and a push plate 9 is fixedly installed on the end of the electric push rod 8. The push plate 9 is a right-angled triangle block structure, and the inclined surface of the push plate 9 corresponds to the lower end of the spherical head 1; when the electric push rod 8 is started, the electric push rod 8 uses the push plate 9 at its end to push the spherical head 1 to deform, so that the material inside the spherical head 1 is squeezed out, thereby achieving the purpose of unblocking.

[0040] In actual use, pressure sensors and other structures can be installed on the spherical head 1 or the feed pipe 5 and the discharge pipe 6. The pressure sensors can be used to determine whether there is blockage inside the spherical head 1. If there is blockage, the pressure will usually increase. Therefore, the electric push rod 8 can be started by program control to automatically achieve the purpose of monitoring and clearing the blockage.

[0041] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
