Description

Technical Field

[0001] This utility model relates to the technical field of impeller cleaning equipment, and in particular to a turbine impeller cleaning machine. Background Technology

[0002] Turbine machinery is a type of rotating machinery that uses high-speed fluid impacting the impeller to achieve energy conversion. It is widely used in power generation, aviation, chemical industry, refrigeration and other fields. Its core components include impeller, rotor, stator and sealing devices. The impeller is driven by the kinetic or thermal energy of the fluid, converting fluid energy into mechanical work or vice versa. It is a key piece of equipment in industrial power systems. During long-term operation of turbine machinery, the impeller surface may experience performance degradation due to impurities, corrosion products or scale deposits carried by the fluid. Therefore, turbine impeller cleaning is an important step in maintaining its efficient and stable operation. By removing the deposits on the impeller surface, the flow channel is restored and the aerodynamic performance is improved, thereby ensuring the energy conversion efficiency and operational reliability of the turbine machinery.

[0003] In turbine impeller cleaning operations, conventional methods mostly employ manual operation. However, manual operation requires a large amount of labor, leading to increased labor intensity and higher labor costs. Secondly, manual cleaning is inefficient, with long cleaning cycles for individual impellers and inconsistent cleaning results, often resulting in localized residues or secondary contamination. Furthermore, the long time required for manual cleaning in the cleaning room reduces equipment resource utilization and affects the cleaning schedule of other workpieces awaiting processing. Therefore, a turbine impeller cleaning machine is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a turbine impeller cleaning machine.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0006] A turbine impeller cleaning machine includes a housing and a cover covering the top of the housing. The housing is equipped with a clamping and positioning mechanism for stabilizing and rotating the turbine impeller. The clamping and positioning mechanism includes a support plate fixedly installed on the inner surface of the housing, a vertical transmission rod rotatably installed in the middle of the support plate, and a horizontal transmission rod installed inside the housing and below the support plate. A rotating platform for supporting the turbine impeller is fixedly installed in the middle of the top of the vertical transmission rod. A high-pressure spray cleaning mechanism for cleaning the turbine impeller is provided in the middle of the cover.

[0007] Preferably, the transverse transmission rod is rotatably mounted to the housing, and the transverse transmission rod and the vertical transmission rod are driven by a bevel gear assembly. Furthermore, the outer end of the transverse transmission rod is connected to the output end of an external motor via a coupling.

[0008] Preferably, the outer surface of the rotating platform has three grooves arranged in a ring at equal intervals, and the inner wall of the grooves is slidably provided with clamping blocks for clamping the turbine impeller. The lower surface of the rotating platform is fixedly provided with threaded rods at the position of each clamping block, and a positioning rod is fixedly inserted in the middle of the upper surface of the rotating platform. The outer surface of the clamping block is provided with a friction-enhancing pad on the side facing the turbine impeller.

[0009] Preferably, the clamping block is slidably sleeved on the outer surface of the threaded rod, and a return spring and a locking nut are respectively provided on both sides of the outer surface of the threaded rod. The clamping block and the threaded rod are elastically set by the return spring.

[0010] Preferably, the high-pressure spray washing mechanism includes a water supply pipe installed in the middle of the upper surface of the cover, and a plurality of nozzle pipes arranged at equal intervals on the top of the inner surface of the cover. Each nozzle pipe is connected to the water supply pipe and is in communication with the water supply pipe. A plurality of high-pressure nozzles arranged at equal intervals are installed on the outer surface of the nozzle pipe. A water inlet is provided at the outer end of the water supply pipe. The high-pressure spray washing mechanism also includes an external water pipe and a water pump, and the two ends of the water pipe are respectively connected and assembled to the water inlet and the water pump.

[0011] Preferably, the bottom of the box is provided with a drain outlet for discharging wastewater, and observation windows are symmetrically installed at both ends of the box, and handles are symmetrically installed on both sides of the upper surface of the cover.

[0012] The beneficial effects of this utility model are:

[0013] By combining a high-pressure spraying mechanism with a clamping and repositioning mechanism, automatic cleaning of the turbine impeller is achieved. During cleaning, an external motor drives a horizontal transmission rod, which in turn drives a vertical transmission rod via a bevel gear assembly, rotating at a low and uniform speed with the rotating table. Simultaneously, high-pressure water enters the water supply pipe through the water inlet, is distributed to each nozzle pipe, and is then sprayed evenly from the high-pressure nozzles. The continuous rotation of the turbine impeller ensures that the high-pressure water flow effectively covers most of its surface, quickly removing dirt. After cleaning, the motor switches to high-speed mode, using centrifugal force to spin off the remaining water. This method achieves automated operation from clamping, cleaning to dehydration, not only reducing manual labor intensity and costs but also ensuring consistent and efficient cleaning results through mechanical collaboration, shortening the cleaning cycle for a single piece.

[0021] The following will combine Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides a technical solution: a turbine impeller cleaning machine, including a housing 100 and a cover 200 covering the top of the housing 100. The cover 200 and the housing 100 are not connected by fasteners and can be disassembled. The turbine impeller is located inside the housing 100. The bottom of the housing 100 is provided with a drain outlet 101 for discharging wastewater. Observation windows 102 are symmetrically installed at both ends of the housing 100 to facilitate real-time observation of the cleaning status of the turbine impeller. Handles 201 are symmetrically installed on both sides of the upper surface of the cover 200 to facilitate disassembly and reassembly of the cover 200. The housing 100 is provided with a clamping and shifting mechanism 400 for stabilizing and rotating the turbine impeller. The middle of the cover 200 is provided with a high-pressure spraying mechanism 300 for cleaning the turbine impeller.

[0023] Specifically, the clamping and shifting mechanism 400 includes a support plate 403 fixedly installed on the inner surface of the housing 100, a vertical transmission rod 402 rotatably disposed in the middle of the support plate 403, and a horizontal transmission rod 404 disposed inside the housing 100 and below the support plate 403. The horizontal transmission rod 404 is arranged perpendicularly to the vertical transmission rod 402, and the horizontal transmission rod 404 is rotatably disposed with respect to the housing 100. The horizontal transmission rod 404 and the vertical transmission rod 402 are driven by a bevel gear assembly 405. The outer end of the horizontal transmission rod 404 is connected to the output end of an external motor via a coupling. The preferred motor is a variable frequency motor, which is not shown or labeled in the accompanying drawings. As it is prior art, it will not be described in detail here. A rotating platform 401 for supporting the turbine impeller is fixedly installed at the middle of the top of the vertical transmission rod 402. The turbine impeller is placed in the middle of the upper surface of the rotating platform 401. Thus, the horizontal transmission rod 404, the bevel gear assembly 405, the vertical transmission rod 402, and the rotating platform 401 can drive the turbine impeller to rotate at high speed, using centrifugal force to clean the residual water on its outer surface. Because a variable frequency motor is used, the speed can be reduced during turbine impeller cleaning. The outer surface of the rotary table 401 has three equally spaced, annular grooves 408. Clamping blocks 407 for clamping the turbine impeller are slidably mounted on the inner wall of each groove 408. The clamping blocks 407 have an I-shaped design in the middle. A threaded rod 411 is fixedly mounted on the lower surface of the rotary table 401 at the position of each clamping block 407. The clamping block 407 is slidably fitted onto the outer surface of the threaded rod 411. A return spring 410 and a locking nut 412 are respectively mounted on both sides of the outer surface of the threaded rod 411. The clamping block 407 is located between the return spring 410 and the locking nut 412. The rod 411 is elastically set by the return spring 410, and the locking nut 412 is engaged with the threaded rod 411 by the thread. Thus, the operator only needs to turn the locking nut 412 to push the clamping block 407 towards the turbine impeller until the clamping block 407 clamps the turbine impeller. The outer surface of the clamping block 407 and the side facing the turbine impeller are provided with a friction-enhancing pad 409 to increase the friction at the joint, reduce slippage, and prevent the surface of the turbine impeller from being scratched. A positioning rod 406 is fixedly inserted in the middle of the upper surface of the rotating table 401 to facilitate the operator's positioning of the turbine impeller.

[0024] Specifically, the high-pressure spray cleaning mechanism 300 includes a water supply pipe 303 installed in the middle of the upper surface of the cover 200, and multiple nozzle pipes 304 arranged at equal intervals on the top of the inner surface of the cover 200. Each nozzle pipe 304 is connected to the water supply pipe 303. Multiple high-pressure nozzles 301 arranged at equal intervals are installed on the outer surface of the nozzle pipes 304 for spraying high-pressure water onto the turbine impeller. With the slow-rotating turbine impeller, the dirt on its outer surface can be effectively removed. The outer end of the water supply pipe 303 is provided with a water inlet 302. The high-pressure spray cleaning mechanism 300 also includes an external water pipe and a water pump. The two ends of the water pipe are connected to the water inlet 302 and the water pump, respectively. The water pump is connected to an external water source.

[0025] Based on the above, this utility model achieves automatic cleaning of the turbine impeller by combining the high-pressure spray cleaning mechanism 300 with the clamping and shifting mechanism 400. Specifically, the operator opens the cover 200 through the handle 201, places the turbine impeller on the rotating table 401 and positions it using the positioning rod 406, and rotates the locking nut 412 to drive the clamping block 407 to move along the slide groove 408. Under the action of the return spring 410 and the friction-enhancing pad 409, the impeller is firmly clamped. During cleaning, the external motor drives the horizontal transmission rod 404, which in turn drives the vertical transmission rod 402 through the bevel gear assembly 405. While the rotating table 401 rotates at a low and uniform speed, high-pressure water enters the water supply pipe 303 through the water inlet 302, is distributed to each nozzle pipe 304, and is then sprayed evenly from the high-pressure nozzle 301. The continuous rotation of the turbine impeller ensures that the high-pressure water flow can effectively cover most of the surface, quickly removing dirt. After cleaning, the motor switches to high-speed mode and uses centrifugal force to spin off the remaining water. This method realizes the automation of the operation from clamping, cleaning to dehydration, which not only reduces the intensity and cost of manual labor, but also ensures the consistency and high efficiency of the cleaning effect through mechanical cooperation, and shortens the cleaning cycle of a single piece.

[0026] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
