Description

TECHNICAL FIELD

[0001] The utility model relates to steel wire production and manufacturing technical field especially relates to a multipurpose cleaning blowing nozzle. BACKGROUND

[0002] In the steel wire production process, the steel wire needs to be pickled and alkali washed. When the steel wire passes through the pickling tank and the alkali washing tank, different acid solution and alkali solution respectively react with the oxides on the surface of the steel wire, thereby removing the oxide skin and rust. After pickling and alkali washing, the steel wire needs to be dried to remove the liquid and prevent the liquid from adhering to the surface of the steel wire and being carried into the next process.

[0003] For example, the acid solution after pickling is removed. One end of the pickling tank is provided with a gas collection box. The gas collection box is a hollow box with two open ends. Compressed air enters the gas collection box through the openings at both ends. A plurality of high-pressure nozzles are arranged in a linear manner in the gas collection box. The high-pressure nozzle is a pipe body. The high-pressure nozzle penetrates the gas collection box. The side wall of the high-pressure nozzle has a hole, thereby connecting the inside of the high-pressure nozzle and the inside of the gas collection box, and supplying compressed air in the high-pressure nozzle. As shown in Figure 1 , the A arrow in the figure indicates that the compressed air enters the gas collection box, and the B arrow indicates the running direction of the steel wire.

[0004] Each steel wire passes through the high-pressure nozzle after pickling. When the high-pressure nozzle is applied, compressed air is uniformly supplied to a plurality of high-pressure nozzles through the gas collection box. The hole in the high-pressure nozzle is used to blow off the liquid. The liquid is trapped in the pickling tank to prevent the liquid from flowing to the next process.

[0005] The high-pressure nozzle used by our unit is a sandwich structure. There is another layer of pipeline inside. The sandwich gap between the inner and outer pipelines is small. Once the surface of the steel wire has dirt, it is easy to block. The airflow is not smooth, and it is difficult to dry the liquid. Moreover, the high-pressure nozzle needs to be supplied with air by a high-pressure blower, which has high energy consumption. The hole in the high-pressure nozzle penetrates along the radial direction. After the air flows through the hole, it will blow to both ends of the high-pressure nozzle. It is difficult to completely blow off the liquid. The airflow can only blow in the opposite direction of the movement direction of the steel wire to effectively remove the liquid.

[0006] When the steel wire is continuously running, it will deviate in the high-pressure nozzle, which will cause wear to the inlet end of the high-pressure nozzle. Not only that, but the acid and alkali solutions will also corrode the high-pressure nozzle to some extent, affecting the normal use of the high-pressure nozzle. SUMMARY

DETAILED DESCRIPTION

[0024] The specific embodiments of the utility model will be described in detail below in combination with the drawings:

[0025] Example one:

[0026] As Figure 2 shown, a multipurpose cleaning air blowing nozzle is used for blowing off liquid on the surface of steel wire to avoid the liquid flowing to the next process. The air blowing nozzle comprises an air cylinder 4, a limiting ring 5, a limiting nut 6 and a wear-resistant sleeve. The air cylinder 4 is a tubular structure, here the air cylinder 4 is a circular tube made of PEEK or PVDF material, and thus the air cylinder 4 has good corrosion resistance. The length of the air cylinder 4 is 100 mm, the outer diameter is 20 mm, and the inner diameter is 10 mm. The inside of the air cylinder 4 is a steel wire channel 12, and the steel wire in production runs through the air cylinder 4 from the steel wire channel 12.

[0027] When the air cylinder 4 is installed, it is still installed on the existing gas collecting box, and the air cylinder 4 is supplied with air by the gas collecting box. Specifically, the limiting ring 5 and the limiting nut 6 are arranged at the two ends of the air cylinder 4, respectively, here the limiting ring 5 is located at the left end of the air cylinder 4, the limiting ring 5 and the left end of the air cylinder 4 are integrally formed, the limiting ring 5 protrudes from the outer wall of the air cylinder 4, and the limiting ring 5 and the air cylinder 4 are combined in a stepped shaft shape after connection. The limiting nut 6 is located at the right end of the air cylinder 4, and the right end of the air cylinder 4 is threadedly connected with the limiting nut 6. After the air cylinder 4 passes through the gas collecting box, the limiting nut 6 is screwed, and then the air cylinder 4 is fixed on the gas collecting box by cooperation of the limiting ring 5 and the limiting nut 6.

[0028] One end of the air cylinder 4 is provided with a wear-resistant sleeve, which plays a role of wear resistance and reduces the abrasion of the steel wire in operation contacting the air cylinder 4. The wear-resistant sleeve can be installed at the left end or the right end of the air cylinder 4; the wear-resistant sleeve is one of a ceramic mold core 7 and a bearing steel mold core 8, and thus the wear-resistant sleeve has different types. Therefore, the different types and installation positions of the wear-resistant sleeve can facilitate the air cylinder 4 to be applied in different environments of pickling and alkaline washing, and realize the multipurpose of the air blowing nozzle.

[0029] In this embodiment, the air cylinder 4 is made of PVDF material, and a ceramic mold core 7 is arranged at the left end of the air cylinder 4 to form a pickling air blowing nozzle, which is applied in the environment of blowing off the acid liquid on the surface of the steel wire after pickling. The ceramic mold core 7 is a circular ring body made of ceramic, and the ceramic mold core 7 is embedded into the inside of the air cylinder 4 and is adhesively fixed with the air cylinder 4.

[0030] Specifically, a hole is formed at the left end of the air duct 4, the hole has a diameter larger than that of the steel wire channel 12, acid-resistant glue is coated on the outer wall of the ceramic mold core 7, the ceramic mold core 7 is sleeved into the hole, and the ceramic mold core 7 is fixed by adhesion. After installation, the ceramic mold core 7 and the steel wire channel 12 are in communication, and the inner diameter of the ceramic mold core 7 is consistent with the diameter of the steel wire channel 12.

[0031] In order to limit the installation, one end of the ceramic mold core 7 is outwardly bent to form an annular outer limiting section 9, which is equivalent to an outward flange. The outer limiting section 9 abuts against the left end of the air duct 4, and the inner wall of the ceramic mold core 7 and the outer limiting section 9 are circularly transitioned. When the air duct 4 is applied in an acid washing environment, the limiting nut 6 on the air duct 4 is made of PEEK or PVDF material to improve the corrosion resistance of the limiting nut 6.

[0032] At least two groups of air holes are also formed on the side wall of the air duct 4, the number of the air holes is arranged according to the length of the air duct 4, and the number of the air holes is two in this embodiment. The two groups of air holes are arranged at intervals along the axis of the air duct 4. The air holes are close to the wear-resistant sleeve, and since the wear-resistant sleeve is the ceramic mold core 7, the air holes are close to the ceramic mold core 7.

[0033] Each group of air holes includes a plurality of air blowing holes 10 uniformly distributed in a ring shape, the number of the air blowing holes 10 in each group of air holes is 3-4, and the air blowing holes 10 in the adjacent two groups of air holes are arranged in a staggered manner. The distance between the air blowing holes 10 in the adjacent two groups of air holes is 15-25 mm, and preferably, the distance between the air blowing holes 10 in the adjacent two groups of air holes is 20 mm. The air blowing hole 10 is a circular hole, and the diameter of the air blowing hole 10 is 4 mm. The air blowing hole 10 is in communication with the steel wire channel 12, the air blowing hole 10 is inclined towards the wear-resistant sleeve, and the axis of the air blowing hole 10 and the axis of the steel wire channel 12 form an included angle A, which is in the range of 30-40°, and preferably, the included angle A is 35°. The air blowing hole 10 close to the ceramic mold core 7 is 30 mm away from the left end surface of the air duct 4.

[0034] When the acid washing air blowing nozzle is applied, it is installed on the gas collecting box above the acid washing tank, the steel wire passes through the steel wire channel 12 from the left end to the right end of the air duct 4, the airflow in the gas collecting box is obliquely blown to the ceramic mold core 7 through the air blowing hole 10, and then the acid liquid attached to the steel wire is intercepted in the ceramic mold core 7 by the high-speed airflow and flows out of the ceramic mold core 7, avoiding the acid liquid from flowing into the right end of the air duct 4 and flowing to the next process. The ceramic mold core 7 can be used in an acidic environment for a long time and has a certain wear resistance, which can reduce the wear of the steel wire on the air duct 4.

[0035] Example Two

[0036] This embodiment is basically the same as example one, and the same parts will not be described again. The difference is that, as shown in FIG. 2, the ceramic mold core 7 is not sleeved into the hole formed at the left end of the air duct 4, but is fixed to the air duct 4 by a limiting nut 6. Figure 3As shown, the air cylinder 4 is made of PEEK material, and a bearing steel mold core 8 is arranged at the right end of the air cylinder 4 to form an alkali washing air nozzle. The alkali washing air nozzle is used in the blowing environment of the alkali solution on the surface of the steel wire after alkali washing. The bearing steel mold core 8 is a circular ring body made of bearing steel, and the inner wall of the bearing steel mold core 8 is provided with a rounded corner at both ends.

[0037] When the bearing steel mold core 8 is installed, the bearing steel mold core 8 is embedded into the inside of the air cylinder 4, that is, a hole is opened at the right end of the air cylinder 4, and the diameter of the hole is greater than the diameter of the steel wire channel 12. The bearing steel mold core 8 is directly sleeved into the hole, so that the bearing steel mold core 8 and the steel wire channel 12 are communicated, and the inner diameter of the bearing steel mold core 8 is consistent with the diameter of the steel wire channel 12. The limiting nut 6 is used to limit the bearing steel mold core 8 to prevent it from being separated from the air cylinder 4.

[0038] The limiting nut 6 on the air cylinder 4 is a nut made of 316 stainless steel, one end of which is inwardly bent to form an annular inner limiting section 11, which is equivalent to an inward flange. The inner limiting section 11 abuts against one end surface of the bearing steel mold core 8, so as to fix the bearing steel mold core 8 on the air cylinder 4. When the air cylinder 4 is used in the alkali washing environment, the blowing hole 10 is inclinedly arranged towards the bearing steel mold core 8, and the blowing hole 10 close to the bearing steel mold core 8 is 30 mm away from the right end surface of the air cylinder 4.

[0039] When the alkali washing air nozzle is used, it is installed on a gas collecting box above an alkali washing tank. The steel wire passes through the steel wire channel 12 from the right end to the left end of the air cylinder 4. The gas flow in the gas collecting box is obliquely blown to the bearing steel mold core 8 through the blowing hole 10, and the gas flow meets the steel wire. Then, the alkali solution attached to the steel wire is intercepted by the high-speed gas flow in the bearing steel mold core 8 and flows out of the bearing steel mold core 8, so as to avoid the alkali solution entering the left end of the air cylinder 4 and flowing to the next process. The bearing steel mold core 8 can be used in the alkaline environment for a long time, and has a certain wear resistance, so as to reduce the wear of the steel wire on the air cylinder 4.

[0040] The above-described embodiments are only preferred embodiments of the present application, and do not limit the scope of the application. Therefore, equivalent changes or modifications made according to the structure, features and principles described in the patent range of the present application should be included in the patent range of the present application.
