Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an atomizing nozzle base. Background Art

[0002] Molten steel refers to liquid steel, that is, steel that changes from solid to liquid at high temperature. Molten steel processing mainly refers to the formation of steel ingots or billets through a casting process of the molten steel smelted in a steelmaking furnace, so that it can be subsequently processed into various shapes and sizes. The atomizing nozzle is an instrument used for molten steel processing, and the base belongs to the component structure of the atomizing nozzle.

[0003] However, it still has the following disadvantages in actual use:

[0004] The base of the existing atomizing nozzle is provided with a cylindrical cavity structure in the middle during the atomization of molten steel. However, during use, the atomized molten steel is easily adhered to the inner wall of the cavity, which reduces the powder recovery rate and may cause burning in severe cases. Utility Model Content

[0005] The purpose of the utility model is to provide an atomizing nozzle base to solve the problem raised in the above-mentioned background technology that the base of the existing atomizing nozzle has a cylindrical cavity structure in the middle during the atomization of molten steel, but during use, the atomized and sprayed molten steel is very easy to adhere to the inner wall of the cavity, which reduces the powder recovery rate and may cause burning in serious cases.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is an atomizing nozzle base, comprising:

[0008] A nozzle base portion, the nozzle base portion comprising a base body, a connecting ring, and a cavity;

[0009] The connecting ring is fixed to the inner edge of the upper end of the base body, and the inner side of the connecting ring is threadedly connected with the atomizing nozzle body. The cavity is opened in the middle of the base body, and the cavity is set to be conical in shape, and the diameter increases from top to bottom.

[0010] Further, the nozzle base portion also includes a peephole;

[0011] The peephole is penetrated and opened on one side of the outer surface of the base body and communicated with the cavity.

[0012] Furthermore, the base body is made of stainless steel.

[0013] Furthermore, it also includes a blocking portion, which includes a blocking column, a connecting hole, and a connecting column;

[0014] One end of the blocking column extends into the peephole, and a connecting hole is opened in the middle of the other end of the blocking column, and the connecting column is sleeved in the connecting hole.

[0015] Furthermore, one end of the blocking column is provided with an arc surface and is tangent to the inner end of the peephole.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The utility model sets the original column-shaped cavity in the middle of the base body into a conical cavity, thereby increasing the spraying range, effectively preventing the molten steel from adhering to the inner wall of the cavity, helping to improve the powder recovery rate and reducing the probability of burning.

[0018] Based on the above beneficial effects, the provided blocking column can, on the one hand, block the peephole to avoid leakage and further improve the recovery rate; on the other hand, it can be used in conjunction with the connecting holes and connecting columns to structurally limit a group of connected base bodies, which is beneficial to subsequent storage needs.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-4 As shown, this embodiment is an atomizing nozzle base, comprising:

[0030] The nozzle base portion includes a base body 21, a connecting ring 22, and a cavity 23;

[0031] The connecting ring 22 is fixed to the inner edge of the upper end of the base body 21, and the inner side of the connecting ring 22 is threadedly connected with the atomizing nozzle body 1. The cavity 23 is opened in the middle of the base body 21, and the cavity 23 is set in a cone shape, and the diameter increases from top to bottom.

[0032] The connecting ring 22 connects the base body 21 and the atomizing nozzle body 1. The threaded connection is convenient for disassembly and assembly. A conical cavity 23 is used in the middle of the base body 21. The atomized molten steel is led out through the cavity 23. The angle of the conical cavity 23 is 15° greater than the angle of the atomizing nozzle body 1, and the optimal atomizing spray angle is 17-20°.

[0033] The nozzle base portion also includes a peep hole 24;

[0034] The peephole 24 is used to view the internal environment of the cavity 23 in real time;

[0035] The peephole 24 is formed through one side of the outer surface of the base body 21 and communicates with the cavity 23;

[0036] The base body 21 is made of stainless steel;

[0037] Made of stainless steel, the base body 21 has good corrosion resistance and high temperature resistance;

[0038] Working principle: after the lower end of the atomizing nozzle body 1 is placed into the connecting ring 22 and the nozzle is extended into the cavity 23, a rotational tightening force is applied to the atomizing nozzle body 1 to fix the two together;

[0039] At this time, when the molten steel is atomized and sprayed out through the atomizing nozzle body 1, the sprayed molten steel is led out through the cavity 23;

[0040] In this solution, the original columnar cavity 23 in the middle of the base body 21 is set to a conical cavity 23, which increases the spraying range and can effectively prevent the molten steel from adhering to the inner wall of the cavity 23, thereby helping to improve the powder recovery rate and reduce the probability of burning.

[0041] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1 and further includes a blocking portion, the blocking portion includes a blocking column 31, a connecting hole 32, and a connecting column 33;

[0042] One end of the blocking column 31 extends into the peephole 24, and a connecting hole 32 is opened in the middle of the other end of the blocking column 31, and the connecting column 33 is sleeved in the connecting hole 32;

[0043] The plugging column 31 plugs the peephole 24 to avoid leakage of molten steel during operation, improve safety, and increase the recovery rate of powder. The connecting hole 32 is connected to the connecting column 33, and the plugging column 31 can be used to install and fix a group of connected base bodies 21;

[0044] One end of the blocking column 31 is provided with an arc surface and is tangent to the inner end of the peephole 24;

[0045] The tangent setting of the arc surface ensures the integrity of the interior of the cavity 23;

[0046] Working principle: After using the peephole 24, one end of the blocking column 31 can be placed into the peephole 24 and an inward force can be applied to block the peephole 24;

[0047] When the base body 21 is stored and placed, the connecting column 33 can be sleeved into the connecting hole 32 of the blocking column 31 connected to the base body 21;

[0048] This solution can, on the one hand, block the peephole 24 to avoid leakage and further improve the recovery rate; on the other hand, it can structurally limit a group of connected base bodies 21 to facilitate subsequent storage needs.
