Description

Technical Field

[0001] The utility model relates to a sintering furnace, in particular to a sintering furnace for powder metallurgy, belonging to the technical field of metallurgical equipment. Background Technique

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and making metals into metal materials with certain properties by various processing methods. Metallurgy has a long development history, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development is integrated with the development history of metallurgy. The technologies of metallurgy mainly include pyrometallurgy, hydrometallurgy, and electrometallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has developed from a process to a science, and thus there is a metallurgical engineering major in universities;

[0003] In the existing metallurgical work, a sintering furnace is needed. However, when the existing sintering furnace is in use, there is no protective structure on its exterior. Therefore, during transportation or hoisting, it is extremely easy to collide with external objects, resulting in deformation or leakage. Once a collision and leakage occur, it will pollute the environment and even cause a fire. Building an isolation foundation requires a large amount of capital investment and there are also potential safety hazards, with insufficient external protection. Summary of the Utility Model

[0004] The utility model provides a sintering furnace for powder metallurgy to solve the problems raised in the background technique.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The sintering furnace for powder metallurgy of the utility model includes a sintering furnace body. An outer protection cage structure is sleeved outside the sintering furnace body. The outer protection cage structure is fixedly connected to the sintering furnace body by welding. No less than five inner reinforcing ribs are inserted inside the sintering furnace body. Between several of the inner reinforcing ribs, they are evenly distributed in a circumferential manner at equal intervals around the center point of the sintering furnace body. One side of the sintering furnace body is fixedly installed with a left-end reinforcing ring by welding, and the other side of the sintering furnace body is fixedly installed with a right-end reinforcing ring by welding. A sitting base is arranged at the bottom end of the sintering furnace body. Arc connecting plates are integrally connected to both sides of the upper surface of the sitting base. The two arc connecting plates on both sides are respectively fixedly connected to the left-end reinforcing ring and the right-end reinforcing ring.

[0007] Furthermore, in order to improve the connection strength between the sitting base and the sintering furnace body, a number of support steel columns are fixedly installed on both sides of the upper surface of the sitting base by welding and are linearly distributed at equal intervals. The tops of several of the support steel columns are fixedly connected to the lower surface of the sintering furnace body.

[0008] Further, in order to improve the internal structural strength of the sitting base, no less than three strengthening grooves are provided inside the sitting base.

[0009] Further, in order to explain the left-end structure, a left port part is fixedly installed on the outer wall of one side of the left-end reinforcing ring.

[0010] Further, in order to explain the right-end structure, a right port part is fixedly installed on the outer wall of one side of the right-end reinforcing ring.

[0011] Further, in order to explain the outer protection cage structure, the outer protection cage structure includes a plurality of outer cage rings, and a plurality of the outer cage rings are linearly and fixedly installed at equal intervals outside the sintering furnace body.

[0012] Further, in order to improve the structural integrity between the outer cage rings, a plurality of outer protection struts are fixedly installed by welding between two adjacent outer cage rings, and a plurality of the outer protection struts are circumferentially distributed at equal intervals through the central dot of the outer cage ring.

[0013] Compared with the prior art, the present utility model provides the following beneficial effects:

[0014] In the present utility model, a plurality of inner reinforcing ribs are arranged at equal intervals inside the sintering furnace body. By means of the arranged inner reinforcing ribs, the overall structural strength of the sintering furnace body itself can be improved, so that the sintering furnace body can effectively resist external force impacts through its own internal structure, avoid deformation from the outside to the inside, and has a good use effect.

[0015] At the same time, an outer protection cage structure is fixedly installed outside the sintering furnace body. By means of the arranged outer protection cage structure, the outside of the sintering furnace body can be protected by a wrapped cage structure. When subjected to external forces, the external forces will first act on the outer protection cage structure, so as to initially resist the impact external forces through the outer protection cage structure, improve the use effect. By cooperating with the use of the inner reinforcing ribs, the sintering furnace of the present utility model has the dual structural strength characteristics of internal and external protection, can effectively avoid collision deformation during transportation or hoisting, avoid leakage of internal materials, reduce potential safety hazards in use, and has a good protection effect.
