[0031] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0032] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] refer to Figure 1-4 An adjustable spray angle nozzle for a fog curtain in a silo of an ironmaking plant includes a dust removal mobile frame 3 for ironmaking plants and a water tank 9. A water inlet pipe 8 is fixedly installed on the right side of the water tank 9, and a fog curtain spraying assembly 1 for the silo of an ironmaking plant is arranged above the water inlet pipe 8 and the water tank 9.

[0034] The mist curtain spraying assembly 1 of the ironmaking plant's material storage silo includes a rotary joint 11, a water supply pipe 12, a rotating shaft 13, and spray nozzles 14. The rotary joint 11 is fixedly installed inside the water inlet pipe 8, and the water supply pipe 12 is rotatably installed on the outside of one end of the rotary joint 11. The rotating shaft 13 is rotatably installed on the front and rear sides between the inner walls of the left and right sides of the water storage tank 9. The spray nozzles 14 are fixedly installed on the left and right sides outside the rotating shaft 13. The rotary joint 11 is existing technology, and it typically contains a rotating component and a fixed component. The fixed component is connected to a fixed rigid pipe, and the rotating component is connected to a rigid pipe that needs to be rotated. Between the two, there is a precision sealing structure and a bearing system. The sealing structure is designed to prevent leakage of fluids such as water, oil, and gas, and it takes various forms. For example, a mechanical seal uses a spring-loaded sealing ring to form a tight contact between the rotating and stationary surfaces, preventing fluid leakage. There is also a packing seal, which uses filling materials such as graphite and fiber to fill the gaps to achieve a sealing effect. Bearing systems such as ball bearings and needle bearings are designed to ensure that rotating parts can rotate smoothly and flexibly relative to fixed parts, reduce friction, and prevent the water supply pipe 12 from getting tangled during rotation.

[0035] In this embodiment, multiple hydraulic telescopic rods 4 are fixedly installed on the top of the dust removal mobile frame 3 for ironmaking plants. Support blocks 5 are fixedly installed on the output ends of the hydraulic telescopic rods 4. A first motor 6 is fixedly installed on the left side of the left support block 5. A first drive shaft 7 is fixedly installed on the output end of the first motor 6. A water tank 9 is fixedly installed on one side of the first drive shaft 7. A water inlet pipe 8 is rotatably installed on the inside of the right support block 5. A nozzle angle adjustment assembly 2 is provided above the ironmaking plant material storage fog curtain spraying assembly 1 and the water tank 9.

[0036] In this embodiment, the mist curtain spraying assembly 1 of the ironmaking plant material storage also includes a pump 15, a connecting pipe 16, and a fixing plate 17. The pump 15 is fixedly installed on the inner walls of the front and rear sides of the water tank 9. The connecting pipe 16 is fixedly installed on one side of the pump 15, and one end of the connecting pipe 16 is fixedly installed on the top of the spray nozzle 14. The fixing plate 17 is fixedly installed on the top left and right sides of the water tank 9. The water supply pipe 12 is connected to the rotary joint 11. The rotary joint 11 is a prior art technology, which makes it easy for the first motor 6 to drive the first drive shaft 7, the water tank 9, and the water inlet pipe 8 to rotate without causing the water supply pipe 12 to rotate and become entangled. This makes the water supply from the water supply pipe 12 to the water inlet pipe 8 more stable and less prone to leakage. The rotation of the first drive shaft 7 and the water tank 9 can control the spraying range of the spray nozzle 14, and the hydraulic telescopic rod 4 can control the spraying height of the spray nozzle 14.

[0037] In this embodiment, the nozzle angle adjustment assembly 2 includes a second motor 20, a second drive shaft 21, an auxiliary shaft 22, a bevel gear 23, a limiting block 24, and a turntable 25. The second motor 20 is fixedly installed on the top inner wall of the water tank 9. The second drive shaft 21 is fixedly installed on the output end of the second motor 20. The auxiliary shaft 22 is rotatably installed on the inner side of the fixing plate 17. The bevel gear 23 is fixedly installed on the outer side of the second drive shaft 21 and the auxiliary shaft 22. Two adjacent bevel gears 23 mesh with each other. The limiting block 24 is fixedly installed on the inner walls of the left and right sides of the water tank 9. Turntables 25 are fixedly installed on the left and right sides of the auxiliary shaft 22.

[0038] In this embodiment, the nozzle angle adjustment assembly 2 further includes a control protrusion 26, a reciprocating sliding rod 27, a transmission gear 28, and a toothed groove 29. The control protrusion 26 is fixedly installed on one side of the turntable 25, the reciprocating sliding rod 27 is slidably installed on the inner side of the limiting block 24, the transmission gear 28 is fixedly installed on the outer side of the rotating shaft 13, and the toothed groove 29 is opened on the front and rear sides of the bottom of the reciprocating sliding rod 27. The transmission gear 28 and the toothed groove 29 mesh with each other. In this embodiment, a control groove is opened on one side of the reciprocating sliding rod 27, and the control protrusion 26 fits into the control groove. The turntable 25 can realize the reciprocating linear motion of the reciprocating sliding rod 27 through the cooperation of the control protrusion 26 and the limiting block 24. The reciprocating sliding rod 27 can drive the transmission gear 28 to rotate through the toothed groove 29. The transmission gear 28 can drive the rotating shaft 13 and the spray nozzle 14 to swing and spray, which is less likely to cause insufficient dust suppression in some areas and water accumulation in some areas, and is less likely to affect the quality of materials and the normal use of the silo floor.

[0039] In this embodiment, the bottom of the dust removal mobile frame 3 for ironmaking plants is provided with multiple mounting slots, and a movable pulley is rotatably installed on the inner side of the mounting slot; the movable pulley facilitates the movement of the device, enabling the device to perform dust removal in different positions.

[0040] In this embodiment, a guide channel is provided on the inner side of the water tank 9, and the water inlet pipe 8 is connected to the guide channel. The guide channel facilitates the flow of water through the pump 15 and the connecting pipe 16 into the inner side of the spray nozzle 14, making the water supply of the device more convenient and faster, and making the weight of the water tank 9 lighter, thereby making the water tank 9 more stable during rotation.

[0041] Specifically, the water supply pipe 12 is connected to the rotary joint 11. The rotary joint 11 is existing technology, which facilitates the rotation of the first motor 6, driving the first drive shaft 7, water tank 9, and inlet pipe 8 without causing the water supply pipe 12 to become entangled. This ensures a more stable and leak-proof water supply from the water supply pipe 12 to the inlet pipe 8. The rotation of the first drive shaft 7 and water tank 9 controls the spraying range of the spray nozzle 14, and the hydraulic telescopic rod 4 controls the spraying height of the spray nozzle 14. During spraying, the second motor 20 can be controlled to drive the second drive shaft 7. The shaft 21 rotates, causing the second drive shaft 21 to drive the turntable 25 to rotate through the cooperation of the bevel gear 23 and the auxiliary shaft 22. The turntable 25 can achieve the reciprocating linear motion of the reciprocating slide rod 27 through the cooperation of the control protrusion 26 and the limit block 24. The reciprocating slide rod 27 can drive the transmission gear 28 to rotate through the tooth groove 29. The transmission gear 28 can drive the rotating shaft 13 and the spray nozzle 14 to swing and spray, which is less likely to cause insufficient dust suppression in some areas and water accumulation in some areas, and is less likely to affect the quality of materials and the normal use of the silo floor.
