Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray rust removal technology, specifically a spherical thermal spray nozzle for rust removal equipment. Background Technology
[0002] Rust removal equipment is a tool used to remove rust from metal surfaces and is widely used in industries such as steel, non-ferrous metals, shipbuilding, automobile manufacturing, bridge construction, and petrochemicals.
[0003] Rust removal equipment comes in various types according to different classification standards, including spray rust removal machines. Existing spray rust removal machines use high-temperature flames or airflow to heat rust remover or thermal spray powder to a molten state, and then spray it onto the metal surface through nozzles to remove rust.
[0004] However, most existing nozzles have a fixed structure, making them inconvenient to adjust. They only have a certain spray intensity and spray range. A few adjustable nozzles adjust the internal flow rate and the angle and shape of the nozzle head. In some cases, it is difficult to change the internal air flow rate. Simply changing the nozzle head and the angle and shape of the nozzle head is not enough to achieve a good adjustment effect. Therefore, it is difficult to adjust the nozzle according to the rust thickness and rust range of the object being rusted. This not only makes the nozzle less flexible, but also increases the nozzle production cost. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a spherical thermal spray nozzle for rust removal equipment. This solves the problem that most existing nozzles have a fixed structure, cannot be adjusted, and only have a certain spraying intensity and spraying range. They cannot be adjusted according to the rust thickness and rust range of the object being removed, resulting in poor nozzle flexibility.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a spherical thermal spray nozzle for a rust removal device includes a spray pipe and a nozzle, wherein the nozzle is installed at one end of the spray pipe, and an adjustment unit is provided on the spray pipe for adjusting the spraying range and spraying intensity of the nozzle.
[0007] The adjustment unit includes:
[0008] A sealing collar, which slides movably on the nozzle, is used to adjust the amount of air entering the nozzle;
[0009] A sleeve, which is rotatably connected to a sealing ring, is used to drive the sealing ring to slide in the nozzle;
[0010] A rotating component, which is fixedly connected to the sleeve, is used to drive the sleeve to rotate.
[0011] Preferably, the sleeve is threaded to the outer wall of the nozzle.
[0012] Preferably, the outer wall of one side of the nozzle is provided with threads, which are used to connect the nozzle to an external feed pipe.
[0013] Preferably, a threaded groove is provided on the outer wall of the other side of the nozzle, and the threaded groove is used for threaded connection between the nozzle and the nozzle.
[0014] Preferably, a ring of holes is formed in the middle of the nozzle to allow air to enter, thereby increasing the amount of air inside the nozzle.
[0015] Preferably, a sealing collar is movably fitted onto the outside of the hole.
[0016] Preferably, the nozzle includes a circular nozzle with a circular hole at its geometric center. The circular nozzle has the characteristics of high pressure and long range, and is used to remove rust from objects that are difficult to remove.
[0017] Preferably, the spray head also includes a square-hole spray head, wherein a trapezoidal hole is provided at the geometric center of the square-hole spray head, with the larger opening facing outward and the smaller opening facing inward. When combined with the adjustment unit, it has the characteristics of a large spraying range and high efficiency, and is used to quickly remove rust from objects with a large area of rust.
[0018] This utility model discloses a spherical thermal spray nozzle for a rust removal device, which has the following beneficial effects:
[0019] The spherical thermal spray nozzle of this rust removal equipment is equipped with replaceable nozzles and adjustment units, allowing the nozzle to be adjusted according to the thickness and extent of rust on the object. For objects with thick rust, a round-hole nozzle with a closed orifice is used, giving the nozzle high pressure and strong spraying intensity, which can remove rust that is difficult to remove. For objects with a large rust area, a square-hole nozzle is used. By rotating the rotating component, the sleeve is rotated, which in turn moves the sleeve on the spray pipe, causing the sealing ring to move away from the orifice, allowing air to enter the spray pipe through the orifice. This increases the spraying area of the nozzle, improves rust removal efficiency, and enhances the practical flexibility of the nozzle. Attached Figure Description

[0026] This utility model discloses a spherical thermal spray nozzle for a rust removal device.
[0027] Example 1
[0028] According to the appendix Figure 1-3 As shown, it includes a spray pipe 1 and a nozzle 2. The nozzle 2 is installed on one end of the spray pipe 1. An adjustment unit 3 is provided on the spray pipe 1, which is used to adjust the spraying range and spraying intensity of the nozzle.
[0029] Adjustment unit 3 includes:
[0030] The sealing ring 31 slides movably on the nozzle 1 and is used to adjust the amount of air entering the nozzle 1.
[0031] Sleeve 32 is rotatably connected to sealing ring 31 and is used to drive sealing ring 31 to slide in nozzle 1.
[0032] Rotating component 33 is fixedly connected to sleeve 32 and is used to drive sleeve 32 to rotate.
[0033] Furthermore, the sleeve 32 is threadedly connected to the outer wall of the nozzle 1.
[0034] Furthermore, a thread 11 is provided on one side of the outer wall of the nozzle 1, which is used to connect the nozzle to the external feed pipe.
[0035] Furthermore, a threaded groove 12 is provided on the outer wall of the other side of the nozzle 1, which is used for threaded connection between the nozzle 2 and the nozzle 1.
[0036] Furthermore, a ring of holes 13 is provided in the middle of the nozzle 1 to allow air to enter, thereby increasing the amount of air inside the nozzle 1.
[0037] Furthermore, the sealing ring 31 is movably connected to the outside of the hole 13. By rotating the rotating part 33, the sleeve 32 is rotated, which in turn moves the sleeve 32 on the nozzle 1, thereby moving the sealing ring 31 away from the hole 13. This allows air to enter the nozzle 1 from the hole 13, increasing the amount of air in the nozzle 1, and making the sprayed airflow stronger and more uniform, so as to cooperate with the square hole nozzle 22 to expand the spraying range.
[0038] Example 2
[0039] According to the appendix Figure 1-3 As shown, it includes a spray pipe 1 and a nozzle 2. The nozzle 2 is installed on one end of the spray pipe 1. An adjustment unit 3 is provided on the spray pipe 1, which is used to adjust the spraying range and spraying intensity of the nozzle.
[0040] Adjustment unit 3 includes:
[0041] The sealing ring 31 slides movably on the nozzle 1 and is used to adjust the amount of air entering the nozzle 1.
[0042] Sleeve 32 is rotatably connected to sealing ring 31 and is used to drive sealing ring 31 to slide in nozzle 1.
[0043] Rotating component 33 is fixedly connected to sleeve 32 and is used to drive sleeve 32 to rotate.
[0044] It is important to emphasize that the nozzle 2 includes a circular nozzle 21, which has a circular hole at its geometric center. It has the characteristics of high pressure and long range, and is used to remove rust from objects that are difficult to remove.
[0045] It should be emphasized that the nozzle 2 also includes a square-hole nozzle 22. The square-hole nozzle 22 has a trapezoidal hole at its geometric center. The larger opening of the trapezoidal hole faces outward and the smaller opening faces inward. Together with the adjustment unit 3, it has the characteristics of a large spraying range and high efficiency, and is used to quickly remove large areas of rust from objects.
[0046] Working principle: First, the nozzle is adjusted according to the thickness and extent of rust on the object. For objects with thick rust, the round nozzle 21 is replaced and the hole 13 is closed by the adjustment unit 3, so that the nozzle has super pressure and improves the spraying intensity, which can remove rust that is difficult to remove or has a large thickness. For objects with a large rust area, the square nozzle 22 is replaced. By rotating the rotating part 33, the sleeve 32 is rotated, which in turn moves the sleeve 32 on the spray pipe 1, which in turn moves the sealing ring 31 away from the hole 13, allowing air to enter the spray pipe 1 from the hole 13, increasing the amount of air in the spray pipe 1, and thus making the sprayed airflow stronger and more uniform, in order to cooperate with the square nozzle 22 to expand the spraying range.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
