Description

Technical Field

[0001] This utility model relates to the field of flange cleaning, and in particular to a cleaning device for fan flanges. Background Technology

[0002] A fan flange typically refers to a disc-shaped structure with bolt holes installed around the edge of a fan inlet, outlet, or fan component (such as casing or impeller). Its main function is to connect and fix it to other pipes, equipment, or components to form a sealed and robust integrated system.

[0003] After long-term operation, fan flanges will accumulate oil, dust, rust, etc., which will lead to a decrease in sealing performance, gas leakage, reduced fan efficiency, and may also affect the performance and safety of the equipment. Therefore, it is necessary to clean and maintain fan flanges regularly.

[0004] For example, patent document CN212143569U discloses a new flange cleaning device that solves the problem of time-consuming and laborious manual cleaning of large flanges. The key technical points are that the base has a groove, and a vertical base plate is fixedly connected in the groove. The base plate has a rotating mechanism, which includes a drive component, a rotating disk, a base block, and a clamping block. The center of the base plate has a rotating shaft that is rotatably connected to it. The rotating disk and the rotating shaft are threadedly locked. The rotating disk is fixedly connected to a positioning screw. There are four positioning screws, which are arranged in pairs and symmetrical about the center of the rotating disk. Each pair of positioning screws includes a first screw and a second screw. The bottom of the first screw and the second screw are fixedly connected to the base plate. The first screw passes through the side hole of the flange, and the second screw is located on the outside of the flange. The flange is located between the clamping block and the base block. The clamping block passes through the first screw and the second screw and is equipped with a locking bolt. The center hole of the flange is coaxially fitted with the rotating shaft with clearance.

[0005] In the above-mentioned device, the flange is fixedly connected to the rotating plate by bolts, thereby driving the flange to rotate and cooperating to achieve the cleaning work. However, the flange with a large size has a large weight. In this case, it is not easy or reliable to fix the flange with bolts. This leaves a safety hazard of loosening during rotation and will also cause part of the flange to be blocked and unable to be cleaned. Utility Model Content

[0006] The purpose of this invention is to provide a cleaning device for fan flanges in order to solve the above-mentioned problems.

[0007] This utility model achieves the above objectives through the following technical solutions: A fan flange cleaning device includes a main body, which includes a base. Several hydraulic telescopic rods are fixedly connected to the base. A support and positioning mechanism is provided on each hydraulic telescopic rod.

[0010] Preferably, the centering drive assembly includes a bidirectional screw rotatably connected to the lower end of the lifting bracket, a clamping motor fixedly connected to the lower end of the lifting bracket, and the clamping motor connected to the bidirectional screw via an orthogonal bevel gear set. Two clamping wheel brackets, symmetrically arranged on the left and right sides, are threaded onto the bidirectional screw. The clamping wheel brackets are slidably connected to the lifting bracket and rotatably connected to the driven clamping wheel. Preferably, the air drying mechanism includes an air guide box fixedly connected to the lifting bracket. The air guide box is Y-shaped and located between two fixed wheel brackets. A fan is fixedly connected to the bottom of the air guide box, an electric heating wire assembly is fixedly connected inside the air guide box, and two exhaust heads symmetrically arranged front and rear are fixedly connected to the top of the air guide box.

[0014] The beneficial effects are as follows: by setting up the driving wheel and the driven clamping wheel, the large flange is automatically positioned by its own weight and the clamping of the two driven clamping wheels. Then, after the large flange descends into the flushing tank, the two clamping rollers automatically center and clamp the large flange, thus ensuring that the large flange does not shake excessively during rotation. This enables the flange to be quickly and stably assembled on the device, facilitating the complete cleaning of the flange surface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8As shown, a fan flange cleaning device includes a main body, which includes a base 101. Two hydraulic telescopic rods 102 are welded to the base 101. A support and positioning mechanism is provided on each hydraulic telescopic rod 102. The support and positioning mechanism includes an inverted T-shaped lifting bracket 201. Two fixed wheel brackets 202 are welded to the upper end of the lifting bracket 201. A drive wheel 203 is rotatably connected to the fixed wheel brackets 202 via bearings. A large flange 6 is placed on the drive wheel 203. A centering drive assembly is provided at the lower end of the lifting bracket 201. Driven clamping wheels 209 are rotatably connected to the left and right ends of the centering drive assembly, and the driven clamping wheels 209 abut against the large flange 6. A drying mechanism is provided at the upper end of the lifting bracket 201. A closed box is provided at the front of the base 101. The closed box includes a rinsing box 401 fixedly connected to the base 101, and the rinsing box 401 is inverted diamond shape. Two clamping rollers 406, arranged in a front-to-back mirror configuration, are elastically connected to the left and right sides of the rinsing tank 401. A rinsing mechanism is installed inside the rinsing tank 401. During use, the operator places the large flange 6 onto the two drive wheels 203 using a hoisting device. Then, the centering drive assembly causes the two driven clamping rollers 209 to clamp the large flange 6. The weight of the large flange 6 and the clamping action of the two driven clamping rollers 209 achieve automatic positioning of the large flange 6. Subsequently, the hydraulic telescopic rod 102 drives the lifting bracket 201 to descend, and the large flange 6 enters the rinsing tank 401. During this process, the two clamping rollers 406 automatically center and clamp the large flange 6, ensuring that the large flange 6 does not wobble excessively during rotation. Then, the drive wheels 203 rotate, driving the large flange 6 to rotate. The rinsing mechanism sprays high-pressure water jets onto the surface of the large flange 6 inside the rinsing tank 401, thereby cleaning the surface of the large flange 6.

[0021] A rear support 103 is fixedly connected to the rear side of the base 101. Two slide rails 104 are fixedly connected to the front side of the rear support 103. The lifting bracket 201 is slidably connected to the slide rails 104. In use, the rear support 103 and the slide rails 104 ensure the stability of the lifting bracket 201 during the lifting process.

[0022] A rotating motor 204 is fixedly connected to the lifting bracket 201. A drive gear 206 is fixedly connected to the output end of the rotating motor 204. A driven gear 205 is fixedly connected coaxially to the rear side of the drive wheel 203. The drive gear 206 meshes with the two driven gears 205. In use, the rotating motor 204 drives the drive gear 206 to rotate, the drive gear 206 drives the driven gear 205 to rotate, the driven gear 205 drives the drive wheel 203 to rotate, and the drive wheel 203 drives the large flange 6 to rotate.

[0023] The centering drive assembly includes a bidirectional screw 207 rotatably connected to the lower end of the lifting bracket 201 by a bearing. A clamping motor 211 is fixedly connected to the lower end of the lifting bracket 201. The clamping motor 211 and the bidirectional screw 207 are connected by an orthogonal bevel gear set 210. Two clamping wheel brackets 208 are threadedly connected to the bidirectional screw 207 and are symmetrically arranged on the left and right. The clamping wheel brackets 208 are slidably connected to the lifting bracket 201. The clamping wheel brackets 208 are rotatably connected to the driven clamping wheel 209 by a bearing. In use, the clamping motor 211 drives the bidirectional screw 207 to rotate through the orthogonal bevel gear set 210. The bidirectional screw 207 drives the two clamping wheel brackets 208 to move synchronously in opposite directions. The clamping wheel brackets 208 drive the driven clamping wheel 209 to move until it clamps the large flange 6. According to the shape and parameters of the large flange 6, the driven clamping wheel 209 can achieve positioning and clamping of the large flange 6 by abutting against the inner or outer ring of the large flange 6.

[0024] The air drying mechanism includes an air guide box 301 fixedly connected to the lifting bracket 201. The air guide box 301 is Y-shaped and located between two fixed wheel brackets 202. A fan 302 is fixedly connected to the bottom of the air guide box 301. An electric heating wire assembly 304 is fixedly connected inside the air guide box 301. Two exhaust heads 303 are fixedly connected to the top of the air guide box 301 and arranged symmetrically. In use, the fan 302 rotates to introduce the outside airflow into the air guide box 301. The electric heating wire assembly 304 inside the air guide box 301 generates heat to heat the airflow. The airflow impacts the surface of the large flange 6 through the exhaust heads 303, thus drying the surface of the cleaned large flange 6 and preventing rust.

[0025] A top hard-bristle brush plate 403 is fixedly connected to the top of the rinsing box 401. Two symmetrically arranged side hard-bristle brush plates 402 are fixedly connected to both sides of the rinsing box 401. Two first spring rods 404, arranged in a front-to-back mirror configuration, are fixedly connected to the left and right sides of the rinsing box 401 respectively. A rotating roller frame 405 is fixedly connected to the movable end of the first spring rod 404. The rotating roller frame 405 is rotatably connected to the clamping roller 406. The diameter of the clamping roller 406 gradually decreases from the middle to both ends. The clamping roller 406 can clamp and abut against the large flange 6. In use, the arrangement of the side hard-bristle brush plates 402 and the top hard-bristle brush plate 403 ensures that the large flange 6 will not be obstructed from entering the rinsing box 401, while also preventing high-pressure water from splashing out and cleaning the surface of the large flange 6. The small diameter of the clamping roller 406 at both ends facilitates the entry of the large flange 6. The rotating roller frame 405 ensures that the clamping roller 406 always clamps the large flange 6.

[0026] The rinsing mechanism includes a water tank 501 fixedly connected to the front of the rinsing box 401. A filter assembly is installed inside the water tank 501, using commonly available equipment. The lower end of the water tank 501 is connected to the lower end of the rinsing box 401 via a pipe. A booster pump 502 is fixedly connected to the top of the water tank 501 via a pipe. A water guide pipe assembly 503 is fixedly connected to the output end of the booster pump 502. The water guide pipe assembly 503 is fixedly connected to the inner wall of the rinsing box 401. A spray head 504 is welded onto the water guide pipe assembly 503. The spray head 504 is vertically shaped. Two symmetrically arranged second spring rods 506 are fixedly connected inside the rinsing box 401. A contact wheel bracket 507 is bolted to the movable end of each second spring rod 506. Two driven contact wheels 508 are rotatably connected to the contact wheel bracket 507. The driven contact wheels 508 can contact the large flange 6. Several closed plates 505 are fixedly connected to the wheel bracket 507. The closed plates 505 are slidably connected to the spray head 504. In use, the large flange 6 will abut against the driven abutment wheel 508. The driven abutment wheel 508 is forced to descend, which drives the abutment wheel bracket 507 to descend. The abutment wheel bracket 507 drives the closed plates 505 to descend. The closed plates 505 and the spray head 504 will have relative displacement. As a result, part of the spray nozzle of the spray head 504 will be exposed. After the length of the exposed spray nozzle is roughly the same as the width of the large flange 6, the large flange 6 will stop descending. Then, the booster pump 502 will pump the water in the water tank 501 into the water guide pipe assembly 503. The high-pressure water will impact the surface of the large flange 6 through the spray head 504, thereby cleaning the large flange 6. The cleaned water will fall to the bottom of the flushing tank 401 and then return to the water tank 501 through the pipe.

[0027] Working principle: Workers use a hoisting device to place the large flange 6 onto the two drive wheels 203. Next, the clamping motor 211 drives the bidirectional screw 207 to rotate via the orthogonal bevel gear set 210. The bidirectional screw 207 drives the two clamping wheel supports 208 to move synchronously in opposite directions. The clamping wheel supports 208 drive the driven clamping wheels 209 to move until they clamp the large flange 6. Thus, the weight of the large flange 6 and the clamping action of the two driven clamping wheels 209 achieve automatic positioning of the large flange 6. The next step... The hydraulic telescopic rod 102 drives the lifting bracket 201 to descend, and the large flange 6 enters the flushing tank 401. During this process, the two clamping rollers 406 automatically center and clamp the large flange 6, thus ensuring that the large flange 6 does not wobble excessively during rotation. Next, the large flange 6 will abut against the driven abutment wheel 508, and the driven abutment wheel 508 will be forced to descend. The driven abutment wheel 508 drives the abutment wheel bracket 507 to descend, and the abutment wheel bracket 507 drives the sealing plate 505 to descend. The sealing plate 505 and the spray head 501... 04. Relative displacement occurs, causing the spray head 504 to partially expose its nozzle. Once the exposed nozzle length is approximately the same as the width of the large flange 6, the large flange 6 stops descending. Next, the rotating motor 204 drives the drive gear 206 to rotate, which in turn drives the driven gear 205. The driven gear 205 then drives the drive wheel 203, which in turn drives the large flange 6. Next, the booster pump 502 pumps water from the water tank 501 into the water guide pipe assembly 503. Pressurized water is sprayed onto the surface of the large flange 6 through the water nozzle 504, thereby cleaning the large flange 6. The cleaned water falls to the bottom of the rinsing box 401 and then returns to the water tank 501 through the pipe. Next, the fan 302 rotates to introduce external airflow into the air guide box 301. The heating wire group 304 in the air guide box 301 generates heat to heat the airflow. The airflow impacts the surface of the large flange 6 through the exhaust head 303, thus drying the surface of the cleaned large flange 6 and preventing rust.
