Description

Technical Field

[0001] This utility model relates to slurry conveying technology, and in particular to a wear-resistant spray nozzle that prevents materials from generating eddies. Background Technology

[0002] During slurry transportation, the particles in the slurry rub against the inner wall of the pipe, which can easily cause wear on the inner wall. The wear at the slurry nozzle is particularly severe at the bends due to the turning of the slurry during flow. In addition, the eddies that are easily generated at the bends will exacerbate the wear on the pipe wall, which urgently needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant nozzle that prevents materials from generating eddies, thereby solving the problem of easy wear of existing nozzles used for slurry conveying.

[0004] To address the aforementioned problems, this utility model provides a wear-resistant injection nozzle for preventing material eddies, comprising a cylindrical section and a sealing section. One end of the cylindrical section is open, and the other end of the cylindrical section is connected to the sealing section. A slurry outlet is provided on the side wall of the cylindrical section near the sealing section. A wear-resistant ceramic layer is provided on the inner wall of both the cylindrical section and the sealing section. A semi-conical baffle corresponding to the slurry outlet is provided inside the cylindrical section, with the tip of the semi-conical baffle facing the open end of the cylindrical section. First slurry through holes are evenly distributed on the semi-conical baffle. A horizontal baffle is also provided on the lower side of the semi-conical baffle, and second slurry through holes are evenly distributed on the semi-conical baffle.

[0005] The wear-resistant spray nozzle provided by this utility model for preventing material vortex formation also has the following technical features:

[0006] Furthermore, the semi-conical spoiler is provided with multiple sets of the first slurry through holes arranged along the generatrix of the cone.

[0007] Furthermore, the first slurry through-hole on the semi-conical baffle plate is arranged along the generatrix of the cone and the hole diameter increases sequentially from the inside to the outside.

[0008] Furthermore, the cone bottom of the semi-conical spoiler is welded and fixed at the connection between the cylindrical section and the sealing section.

[0009] Furthermore, the projection of the cone tip of the semi-conical spoiler at the slurry outlet is located on the right side of the slurry outlet.

[0010] Furthermore, both the first slurry through-hole and the second slurry through-hole are round holes.

[0011] Furthermore, the slurry outlet is also provided with a connecting flange, and the connecting flange is provided with a connecting hole.

[0012] This utility model has the following beneficial effects: By setting a wear-resistant ceramic layer on the inner wall of the cylindrical section and the sealing section, the wear of the inner wall of the pipe can be reduced; by setting a semi-conical baffle and a horizontal baffle, the slurry flowing in the upper part of the pipe is diverted by the semi-conical baffle, and part of the slurry flows from the first slurry through-hole to the sealing section, and then flows downward through the second slurry through-hole on the horizontal baffle to the slurry outlet, where it mixes with the slurry flowing in the lower part of the pipe and is discharged through the slurry outlet. This can prevent eddies in the slurry, reduce the wear of the inner wall of the sealing section, and also make the slurry mix evenly. Attached Figure Description

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 5In the embodiment of the wear-resistant spray nozzle for preventing material eddy currents shown in this utility model, the wear-resistant spray nozzle includes a cylindrical section 10 and a sealing section 20. One end of the cylindrical section 10 is open, and the other end of the cylindrical section 10 is connected to the sealing section 20. A slurry outlet 101 is provided on the side wall of the cylindrical section 10 near the sealing section 20. A wear-resistant ceramic layer 102 is provided on the inner wall of the cylindrical section 10 and the sealing section 20. A semi-conical baffle plate 30 corresponding to the slurry outlet 101 is provided inside the cylindrical section 10. The tip of the semi-conical baffle plate 30 faces the open end of the cylindrical section 10. First slurry through holes 31 are evenly distributed on the semi-conical baffle plate 30. A horizontal baffle plate 40 is also provided on the lower side of the semi-conical baffle plate 30. Second slurry through holes 41 are evenly distributed on the semi-conical baffle plate 40. This application reduces wear on the inner wall of the pipe by providing a wear-resistant ceramic layer 102 on the inner wall of the cylindrical section 10 and the sealing section 20; and by providing a semi-conical baffle 30 and a horizontal baffle 40, such as Figure 4 As shown, after the slurry flowing in the upper part of the pipeline is diverted by the semi-conical baffle 30, part of the slurry flows from the first slurry through-hole 31 to the sealing section 20, and then flows downward through the second slurry through-hole 41 on the horizontal baffle 40 to the slurry outlet 101. After mixing with the slurry flowing in the lower part of the pipeline, it is discharged through the slurry outlet. This can prevent eddies in the slurry, reduce wear on the inner wall of the sealing section, and make the slurry mix evenly.

[0020] In one embodiment of this application, preferably, the semi-conical baffle 30 is provided with multiple sets of first slurry through holes 31 arranged along the generatrix of the cone. Preferably, the first slurry through holes 31 on the semi-conical baffle 30 are arranged along the generatrix of the cone and the hole diameter increases from the inside to the outside. That is, the hole diameter of the first slurry through holes 31 increases from the center of the cone to the edge of the cone. This makes the slurry flow velocity at the center of the pipe greater than the slurry flow velocity at the edge of the pipe, and the slurry can be mixed again after passing through the first slurry through holes 31.

[0021] In one embodiment of this application, preferably, as Figures 3 to 5 As shown, the cone bottom of the semi-conical baffle 30 is welded and fixed at the connection between the cylindrical section 10 and the sealing section 10, and the cone tip of the semi-conical baffle 30 faces the opening end of the cylindrical section 10, so that the semi-conical baffle 30 can reliably divert and disturb the slurry.

[0022] In one embodiment of this application, preferably, as Figure 4 As shown, the projection of the cone tip of the semi-conical baffle 31 at the slurry outlet 101 is located on the right side of the slurry outlet 101; that is, the distance between the right edge of the slurry outlet 101 and the sealing section 20 is greater than or equal to the height of the semi-conical baffle 30, so as to avoid the semi-conical baffle affecting the slurry flowing out of the slurry outlet.

[0023] In one embodiment of this application, preferably, the first slurry through hole 31 and the second slurry through hole 32 are both round holes; preferably, the slurry outlet 101 is also provided with a connecting flange 50, and the connecting flange 50 is provided with a connecting hole.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
