Description

Technical Field

[0001] This utility model relates to the field of dust collectors and demisters, specifically to a rotary nozzle for a dust collector and demister. Background Technology

[0002] Industrial waste gas typically contains a large amount of moist dust, which needs to be treated for dust removal and demisting before being discharged. Dust collectors and demisters are usually divided into dust removal systems and demisting systems. Wet electrostatic precipitators are a commonly used dust removal method. Moist flue gas is passed into an electric field, and the dust is adsorbed onto the anode plate by the electric field. Then, a spray system sprays water onto the anode plate, causing the dust to be removed as the sprayed water flows downwards.

[0003] However, the nozzles in the existing spray system are usually rotary nozzles. But ordinary rotary nozzles only rotate the spray direction of the nozzle, and cannot perform more effective wide-range spraying for a certain area, resulting in poor dust removal effect and certain limitations.

One pulley is fixedly connected to the surface of the drive shaft, and the other pulley is fixedly connected to the surface of the driven shaft. The two pulleys are connected by belt drive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the design of a range adjustment mechanism, allows the spraying range of the nozzle to be adjusted. When high-pressure water enters the delivery shell through the inlet pipe, some of the water flow directly impacts the impeller surface, causing the impeller to drive the drive shaft to rotate. The drive shaft, in turn, drives the transmission shaft to rotate simultaneously through the cooperation of the transmission structure and the driven shaft. When the transmission shaft rotates, the rotating frame rotates synchronously with the transmission shaft, allowing the drive rod to slide up and down on the inner wall of the movable frame. The drive rod can also push the movable frame to slide back and forth on the surface of the mounting bracket, thus allowing the movable frame to drive the rack to move through the connecting bracket. This allows the rack to drive the gear ring to rotate back and forth, enabling the delivery pipe to drive the nozzle to rotate within a certain range through the angle adjustment mechanism. Furthermore, the adjustment structure can also adjust the vertical position of the drive rod inside the movable frame. When the drive rod moves to the upper position on the inner wall of the movable frame, it can push the movable frame to move a larger range, thereby expanding the range of motion of the rack and increasing the angle rotation range of the nozzle, thus achieving the effect of adjusting the spraying range of the nozzle.

[0016] 2. Through the design of the angle adjustment mechanism, the spray angle of this utility model can also be adjusted. When it is necessary to adjust the spray angle of the nozzle, the nozzle can be rotated downwards, so that the nozzle can drive the extension tube and the screw to move together. The screw can slide on the inner wall of the arc frame, so that the nozzle can adjust the angle within the arc range. During this period, the corrugated pipe will also extend to ensure that the water flow can be transmitted normally. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1-5 A rotary nozzle for a dust collector and demister includes a conveying shell 1 and a nozzle body 2. The surface of the conveying shell 1 is provided with a range adjustment mechanism 3, and one side of the nozzle body 2 is provided with an angle adjustment mechanism 4. A water inlet pipe 5 is connected to the top of the conveying shell 1.

[0024] The water inlet pipe 5 is used to connect to the external water supply pipeline, the conveying shell 1 allows the water to flow downward normally, the nozzle 2 is used to spray water mist for dust removal, the range adjustment mechanism 3 allows the spraying range of the nozzle 2 to be adjusted, and the angle adjustment mechanism 4 allows the spraying angle of the nozzle 2 to be adjusted.

[0025] The range adjustment mechanism 3 includes a drive shaft 301, one end of which is rotatably connected to the inner wall of the conveying housing 1. An impeller 302 is fixed to the surface of the drive shaft 301, and the other end of the drive shaft 301 extends through the conveying housing 1. A bearing seat 303 is fixed to the surface of the conveying housing 1, and a driven shaft 304 is fixed to the inner wall of the bearing seat 303. A transmission structure is installed between the driven shaft 304 and the surface of the drive shaft 301. A mounting platform 306 and a support plate 307 are fixed to the surface of the conveying housing 1. A drive shaft 310 is rotatably connected to the surface of the mounting platform 306, and a rotating impeller 302 is fixed to one end of the drive shaft 310. The rotating frame 311 has a mounting bracket 308 fixed on the surface of the support plate 307. The mounting bracket 308 is slidably connected to the surface of the movable frame 309. The rotating frame 311 has an adjustment structure inside. The inner wall of the movable frame 309 is slidably connected to the drive rod 314. The bottom of the movable frame 309 is fixed to the connecting bracket 315. The connecting bracket 315 is fixed to the surface of the rack 318. The bottom of the surface of the conveying shell 1 is rotatably connected to the conveying pipe 316. The surface of the conveying pipe 316 is fixed to the rack 318 and the rack 318 meshes with the rack 317. The nozzle body 2 is located below the conveying pipe 316.

[0026] When high-pressure water flows into the conveying housing 1 through the inlet pipe 5, some of the water directly impacts the surface of the impeller 302, causing the impeller 302 to drive the drive shaft 301 to rotate. The drive shaft 301, in turn, drives the transmission shaft 310 to rotate simultaneously through the cooperation of the transmission structure and the driven shaft 304. When the transmission shaft 310 rotates, the rotating frame 311 rotates synchronously with the transmission shaft 310, allowing the drive rod 314 to slide up and down on the inner wall of the movable frame 309. Furthermore, the drive rod 314 can push the movable frame 309 to slide back and forth on the surface of the mounting bracket 308, thus enabling the movable frame 309 to... The rack 318 is moved by the connecting frame 315, which in turn drives the toothed ring 317 to rotate back and forth. This allows the delivery pipe 316 to rotate the nozzle 2 within a certain range through the angle adjustment mechanism 4. The adjustment mechanism can also adjust the vertical position of the drive rod 314 inside the movable frame 309. When the drive rod 314 moves to the position above the inner wall of the movable frame 309, it can push the movable frame 309 to move a larger range, thereby expanding the range of motion of the rack 318 and increasing the angle rotation range of the nozzle 2. This achieves the effect of adjusting the spray range of the nozzle 2.

[0027] Furthermore, the surface transmission structure of the drive shaft 301 and the driven shaft 304 includes two pulleys 305. One pulley 305 is fixedly connected to the surface of the drive shaft 301, and the other pulley 305 is fixedly connected to the surface of the driven shaft 304. The two pulleys 305 are connected by belt drive. A first bevel gear 319 is fixedly mounted on the surface of the driven shaft 304, and a second bevel gear 320 is fixedly mounted on the surface of the drive shaft 310. The first bevel gear 319 and the second bevel gear 320 mesh.

[0028] When the drive shaft 301 rotates, it can drive the driven shaft 304 to rotate synchronously through the transmission of one side pulley 305 and belt and the other side pulley 305. When the driven shaft 304 rotates, it can drive the transmission shaft 310 to rotate normally through the meshing of the first bevel gear 319 and the second bevel gear 320.

[0029] Furthermore, the internal adjustment structure of the rotating frame 311 includes a lead screw 312, the bottom end of which is rotatably connected to the inner wall of the rotating frame 311, the top end of which passes through the rotating frame 311 and is fixed with a handwheel, a slide 313 is threadedly connected to the surface of the lead screw 312, the surface of the slide 313 is slidably connected to the surface of the rotating frame 311, and the surface of the slide 313 is fixedly connected to one end of the drive rod 314.

[0030] The lead screw 312 can be rotated by the handwheel. When the lead screw 312 rotates, the slide table 313 can move on the surface of the lead screw 312. The slide table 313 can also drive the drive rod 314 to move together on the inner wall of the movable frame 309, thereby ensuring that the drive rod 314 can achieve the position adjustment effect.

[0031] Furthermore, the angle adjustment mechanism 4 includes a mounting plate 401, which is fixed to the surface of the conveying pipe 316. A corrugated pipe 404 is connected to the bottom of the conveying pipe 316, and an extension pipe 405 is connected to the bottom of the corrugated pipe 404. The bottom of the extension pipe 405 is connected to the top of the nozzle body 2. A support frame 402 is fixed to the bottom of the mounting plate 401, and an arc frame 403 is fixed to the surface of the support frame 402. A screw 406 is fixed to the surface of the extension pipe 405, and the screw 406 is slidably connected to the inner wall of the arc frame 403.

[0032] When it is necessary to adjust the spray angle of nozzle 2, nozzle 2 can be rotated downwards directly, so that nozzle 2 can drive extension pipe 405 and screw 406 to move together. Screw 406 can slide on the inner wall of arc frame 403, so that nozzle 2 can adjust the angle in an arc range. During this period, corrugated pipe 404 will also extend to ensure that water flow can be transmitted normally.

[0033] Furthermore, a limiting nut 407 is threadedly connected to the surface of the screw 406, and the limiting nut 407 is a wing nut;

[0034] The design of the limiting nut 407 allows the operator to manually twist the limiting nut 407 onto the surface of the screw 406, thereby enabling the limiting nut 407 to limit the extension tube 405 through friction.

[0035] Furthermore, the first bevel gear 319 is larger than the second bevel gear 320;

[0036] By designing the sizes of the first bevel gear 319 and the second bevel gear 320, when the first bevel gear 319 drives the second bevel gear 320 to rotate, the second bevel gear 320 can drive the transmission shaft 310 to achieve an acceleration effect.

[0037] Furthermore, a first slide rail 321 is fixed to the surface of the mounting platform 306, a first slider 322 is slidably connected to the surface of the first slide rail 321, and the surface of the first slider 322 is fixedly connected to the surface of the rotating frame 311.

[0038] The rotating frame 311 can drive the first slider 322 to slide on the surface of the first slide rail 321, thereby providing additional support to the rotating frame 311 and making the rotating frame 311 more stable when rotating.

[0039] Furthermore, a second slide rail 323 is fixed to the bottom of the conveyor housing 1, and a second slider 324 is slidably connected to the surface of the second slide rail 323. The bottom of the second slider 324 is fixedly connected to the top of the rack 318.

[0040] When the movable frame 309 drives the rack 318 to move through the connecting frame 315, the second slider 324 will slide together with the rack 318 on the surface of the second slide rail 323, so that the rack 318 can get a linear guiding effect, thereby ensuring that the rack 318 can maintain linear movement.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
