Description

Technical Field

[0001] The invention belongs to the technical field of water-based cleaning machines, and relates to a water-based cleaning machine using double impellers for enhanced cleaning. Background Art

[0002] Industrial cleaning machines utilize vacuum technology and chemical cleaning to clean metal parts and other components. Existing water-based cleaning machines rely solely on the cavitation effect during ultrasonic cleaning, resulting in uneven cavitation bubble distribution and a lack of synergistic effects such as eddy current-assisted cleaning. This leads to blind spots and residual residue on complex structural parts and dense oil stains. Furthermore, spray cleaning machines typically use a one-way spray method with a single spray angle and insufficient liquid flow coverage, resulting in large blind spots and poor cleaning results. Therefore, there is an urgent need to design a water-based cleaning machine that can overcome these shortcomings and utilize dual-impeller-assisted cleaning.

[0003] To overcome the shortcomings of the existing technology, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a water-based screen cleaning machine [application number: 201110412265.9], which includes a chassis body. The lower portion of the chassis body is provided with a cleaning liquid tank, a rinsing liquid tank, a pneumatic diaphragm pump, a water pump, a rinsing liquid filter device, and a cleaning liquid filter device. The upper portion of the chassis body is provided with a hot air box, a blower, a gear transmission device, a pressure regulating filter device, a spray device, and a cleaning chamber. The various components within the chassis body are simply and reasonably connected by pipes. The cleaning liquid tank is provided with a stirring device, and both the cleaning liquid tank and the rinsing liquid tank are provided with heating pipes, and their shells are both sandwich structures. The spray device is provided with an air knife device. Both can be driven by a gear transmission mechanism to move up and down within the cleaning chamber. After use, the cleaning liquid and rinsing liquid first flow through the cleaning liquid filter device or the rinsing liquid filter device before being recovered or discharged. However, this solution still relies on a single cavitation effect during the cleaning process and lacks eddy current-assisted cleaning, resulting in defects such as uneven distribution of cavitation bubbles, cleaning blind spots, and residual problems.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figure 1-9As shown, a water-based cleaning machine using dual impellers for enhanced cleaning includes a cleaning machine body 1, the cleaning machine body 1 includes a sealing cover 11, a cleaning machine case 12, a support column 14, a drain pipe 15, a one-way valve 16 and a drain port 17, an ultrasonic transducer 13 is provided below the cleaning machine case 12, a cleaning chamber 2 is provided in the cleaning machine case 12, a cleaning basket 22 and a rotating frame 31 that can rotate axially in the cleaning chamber 2 are provided, the cleaning basket 22 and the rotating frame 31 are fixed to each other by a snap-fit ​​structure 100, a spray device 21 for spraying and cleaning the cleaning basket 22 is provided in the cleaning machine case 12, a rotatable bidirectional rotating impeller device 200 is provided below the cleaning basket 22, and a rotating power structure 300 for driving the rotating frame 31 and the bidirectional rotating impeller device 200 to rotate is provided below the rotating frame 31.

[0033] In this embodiment, the cleaning machine body 1 serves as the basic frame, and the sealing cover 11 is hingedly mounted above the cleaning machine housing 12. When closed, the cleaning chamber 2 can be completely sealed to prevent splashing of cleaning liquid and loss of ultrasonic energy. Support columns 14 are mounted at the four corners of the base of the cleaning machine housing 12 to ensure the stability of the equipment during operation. One end of the drain pipe 15 is connected to the drain port 17, and the other end leads to the outside. A one-way valve 16 is mounted on the drain pipe 15 and remains closed during the cleaning process to prevent backflow of the cleaning liquid. It is opened after the cleaning is completed to discharge the sewage. The ultrasonic transducer 13 is fixed below the cleaning machine housing 12. When working, it converts electrical energy into high-frequency mechanical vibrations. A cavitation effect is generated in the washing liquid. In the washing chamber 2, the washing basket 22 and the rotating frame 31 are connected by a snap-fit ​​structure 100 and can rotate with the rotating frame 31. The spray device 21 is arranged in the washing machine housing 12 and can spray the washing liquid to the washing basket 22. The bidirectional rotating impeller device 200 is located below the washing basket 22. The rotating power structure 300 is installed below the rotating frame 31 to provide rotational power for the washing basket 22, the rotating frame 31 and the bidirectional rotating impeller device 200. The ultrasonic transducer 13 works in conjunction with the bidirectional rotating impeller device 200 to achieve multi-dimensional cleaning. The rotating structure cooperates with the spray device 21 to improve the cleaning effect and efficiency.

[0034] The ultrasonic transducer 13 emits ultrasonic waves, which induce microjets in the boundary layer, reducing the thickness d of the laminar bottom layer:

[0035] Combine Figure 1-9As shown, the bidirectional rotating impeller device 200 includes an impeller 23 arranged below the cleaning basket 22, and the impeller 23 is installed at the bottom center position of the cleaning box 12. The diameter of the impeller 23 is the same as the diameter of the rotating frame 31. The impeller 23 is composed of an outer impeller 231 and an inner impeller 232. The inner impeller 232 is tangent to the outer impeller 231 inside and outside. The inner impeller 232 is connected to the rotating power structure 300 through a rotating shaft, and the rotation direction is opposite to that of the outer impeller 231.

[0036] Specifically, the impeller 23 in the bidirectional rotating impeller device 200 is installed at the bottom center of the cleaning machine housing 12, and its diameter is the same as the diameter of the rotating frame 31 to ensure that the generated eddy current can cover the entire cleaning area. The impeller 23 is composed of an outer impeller 231 and an inner impeller 232. The inner impeller 232 is tangent to the inner and outer sides of the outer impeller 231. The inner impeller 232 is connected to the driving wheel 32 in the rotating power structure 300 through a rotating shaft. When working, the rotating power structure 300 drives the inner impeller 232 to rotate. Due to the special tangential structure of the outer impeller 231 and the inner impeller 232, and the influence of the water flow resistance on the outer impeller 231, the outer impeller 231 and the inner impeller 232 rotate in opposite directions. The blades on the surfaces of the outer impeller 231 and the inner impeller 232 stir the water flow, forming a double-circular vortex in the cleaning chamber 2, expanding the flushing range of the cleaning liquid and enhancing the cleaning effect on the workpiece surface. This design breaks through the traditional single-impeller cleaning method and generates more complex water flow motion through the counter-rotating dual impellers, thereby improving the comprehensiveness and effectiveness of cleaning.

[0037] Among them, the vortex forms a spiral centripetal flow, which directionally transports the cavitation bubbles to the traditional ultrasonic blind area. The coverage improvement formula is:

[0038] η c =1-e -kt .

[0039] Combine Figure 1-9 As shown, the outer impeller 231 is mounted with a plurality of blades in an arc shape, and the inner impeller 232 is located at the center of the impeller 23 and is mounted with a plurality of blades on its surface.

[0040] In this embodiment, the arc-shaped blades on the surface of the outer impeller 231 can push the water flow more efficiently during the rotation process, forming a vortex with strong impact force. The inner impeller 232 is located at the center of the impeller 23, and the blades on its surface work together with the blades of the outer impeller 231. The two rotate in opposite directions, causing the water flow to produce a complex motion trajectory of spiral rise or fall. This blade structure design, on the one hand, increases the contact area and flushing force between the water flow and the workpiece, which helps to remove stains over a large area; on the other hand, the complex water flow movement enables the cleaning liquid to better penetrate into the gaps and holes of the workpiece, and cooperates with the cavitation effect generated by the ultrasonic transducer 13 to further enhance the cleaning effect on tiny structures.

[0041] The cleaning basket 22 is in the shape of a cylindrical shell, and a plurality of regularly distributed circular holes are opened on the outside of the cleaning basket 22, and the diameters of the holes are the same.

[0042] In this embodiment, the cleaning basket 22 is in the shape of a cylindrical shell, and a plurality of circular holes of the same diameter are evenly distributed on its outer side. The arrangement of these holes facilitates the free circulation of the cleaning liquid during the cleaning process, so that the cleaning liquid can fully contact the surface of the workpiece, thereby ensuring the uniformity of cleaning. At the same time, in the drying stage, the holes can be used as water discharge channels, and cooperate with the rotating centrifugal effect of the cleaning basket 22 to accelerate the speed of water separating from the workpiece and the cleaning basket 22, thereby improving the drying efficiency. Compared with a cleaning basket without holes or with irregularly distributed holes, the cleaning basket 22 of the present invention optimizes the flow path and drainage performance of the cleaning liquid through the regularly distributed hole design, thereby ensuring the efficient cleaning and drying processes, and avoiding the impact of cleaning liquid residue or poor drainage on the cleaning quality and drying effect.

[0043] Combine Figure 1-9 As shown, the spray device 21 includes a liquid inlet pipeline 211, a spray pipe 212 and a nozzle. The spray pipe 212 is cylindrical and horizontally arranged above the cleaning box 12. The nozzle is installed on the spray pipe 212. The nozzle has a circular hole and the angle between the nozzle and the horizontal direction is 30°.

[0044] In this embodiment, during the spray cleaning stage, the cleaning liquid enters the spray pipe 212 through the liquid inlet pipe 211, and is then sprayed toward the cleaning basket 22 from the nozzle at a 30° angle. When the rotating power structure 300 drives the cleaning basket 22 to rotate, the cleaning liquid sprayed at different angles can flush the workpieces in the cleaning basket 22 in all directions, avoiding cleaning dead corners. Compared with spray devices that spray horizontally or at other angles, the nozzle design at a 30° angle can form a more uniform and wider cleaning coverage area during the rotation of the cleaning basket 22, significantly improving the effect and efficiency of spray cleaning.

[0045] The clamping structure 100 includes four T-shaped grooves 311 provided in the rotating frame 31 , with the angle between adjacent T-shaped grooves 311 being 90°. The outer ring of the cleaning basket 22 is provided with four T-shaped clamping strips 221 , which are clamped and matched with the T-shaped grooves 311 .

[0046] The cleaning basket 22 is fixed to the washing chamber 22 by means of the T-shaped clips 221. When the cleaning basket 22 is placed in the washing chamber 2, it is only necessary to align the T-shaped clips 221 with the T-shaped clips 221 and insert them into the T-shaped clips 311 to achieve a quick and fixed connection between the cleaning basket 22 and the rotating frame 31. During the cleaning process, the rotating frame 31 drives the cleaning basket 22 to rotate synchronously through the clip structure 100. Whether it is the spray cleaning stage or the centrifugal drying stage in the drying stage, the clip structure 100 can ensure that the two are stably connected without loosening or falling off. This clip method has a simple structure and is easy to operate. At the same time, the connection is firm and reliable. Compared with other complex connection methods, it reduces the manufacturing and maintenance costs of the equipment and facilitates the disassembly and replacement of the cleaning basket 22.

[0047] A chassis 312 is provided at the bottom of the rotating frame 31 , and the chassis 312 is disc-shaped.

[0048] In this embodiment, the chassis 312 at the bottom of the rotating frame 31 is disc-shaped, and the chassis 312 is connected to the basket bottom gear 35 up and down. Under the drive of the rotating power structure 300, the basket bottom gear 35 rotates and drives the chassis 312 to rotate in the same direction, thereby driving the entire rotating frame 31 and the cleaning basket 22 connected thereto to rotate. The chassis 312 serves as the basic supporting component of the rotating frame 31. On the one hand, it ensures the stability of the rotation of the rotating frame 31 and avoids shaking or deviation during the rotation process; on the other hand, during the centrifugal drying process in the drying stage, the chassis 312 can withstand the centrifugal force generated by the rotation of the cleaning basket 22 and the workpiece, ensuring the smooth realization of the centrifugal drying function. Its disc-shaped design can evenly distribute the force and improve the overall structural strength and reliability of the rotating frame 31.

[0049] Combine Figure 4-7 As shown, the rotary power structure 300 includes a driving wheel 32, a rotating motor 33, a driven wheel 34 and a basket bottom gear 35. The rotating motor 33 is installed at the center of the outer side of the cleaning box 12. The rotating motor 33 and the driving wheel 32 are connected by a rotating shaft. The driven wheel 34 is installed on one side of the driving wheel 32 and is provided with a transmission ring gear that meshes with the driving wheel 32. The outer side of the basket bottom gear 35 is provided with a transmission ring gear that meshes with the driven wheel 34. The chassis 312 and the basket bottom gear 35 are connected up and down and rotate in the same direction. The inner impeller 232 and the driving wheel 32 are connected by a rotating shaft.

[0050] In this embodiment, when working, the rotating motor 33 is started to drive the driving wheel 32 to rotate. The driving wheel 32 transmits power to the driven wheel 34 through the transmission ring gear. The driven wheel 34 then transmits power to the basket bottom gear 35, thereby driving the chassis 312 and the rotating frame 31 to rotate, realizing the rotation of the washing basket 22. At the same time, the driving wheel 32 directly drives the inner impeller 232 to rotate, realizing the reverse rotation of the dual impellers. This gear transmission structure has high transmission efficiency and good stability, and can accurately control the rotation speed and direction of each component. Through reasonable gear ratios, the rotation speed of the washing basket 22 and the rotation rate of the dual impellers can be adjusted according to different cleaning requirements, ensuring the cleaning effect while improving the applicability and flexibility of the equipment.

[0051] Combine Figure 1 As shown, the sealing cover 11 is located above the cleaning machine case 12 and is in the shape of a rectangular parallelepiped. It is sealed and installed above the cleaning machine case 12 through a hinge structure. The cleaning machine case 12 is in the shape of a rectangular parallelepiped, and the inner and outer walls are made of 304 stainless steel. The support column 14 is located at the four corners of the base of the cleaning machine case 12 and is in the shape of a rectangular parallelepiped as a whole.

[0052] In this embodiment, the cover 11 is located above the cleaning machine case 12 and is sealed by a hinge structure. This installation method is convenient for opening and closing, while ensuring the sealing of the cleaning chamber 2. The cleaning machine case 12 is made of 304 stainless steel, and its inner and outer walls are smooth and corrosion-resistant. It can not only resist the erosion of various cleaning fluids and extend the service life of the equipment, but also facilitate cleaning and maintenance to prevent dirt residue. The support column 14 is located at the four corners of the base of the cleaning machine case 12. The rectangular support column 14 can provide stable support force to ensure that the cleaning machine remains stable during operation and avoid vibration or shaking that affects the cleaning effect and equipment safety.

[0053] Combine Figure 1-2 As shown, one end of the drain pipe 15 is connected to the drain port 17 and the other end is connected to the outside; the one-way valve 16 is installed on the drain pipe 15, and the drain port 17 is located at the bottom of the cleaning machine housing 12 and is provided with a plurality of small holes for drainage.

[0054] In this embodiment, one end of the drain pipe 15 is connected to the drain outlet 17 at the bottom of the cleaning machine case 12. The drain outlet 17 is provided with a plurality of small holes for drainage to facilitate the rapid discharge of sewage; the other end is connected to the external drainage pipe, and a one-way valve 16 is installed on the drain pipe 15. During the cleaning process, the one-way valve 16 is in a closed state to prevent the cleaning liquid from flowing out of the drain pipe 15, thereby ensuring the stability of the liquid level and cleaning environment in the cleaning chamber 2; when the cleaning is completed, the one-way valve 16 is opened, and the solution mixed with pollutants flows into the drain pipe 15 through the small holes of the drain outlet 17 under the action of gravity, and is finally discharged from the equipment. Through the control of the one-way valve 16 and the special structure of the drain outlet 17, effective management of the liquid during the cleaning process is achieved, the waste of cleaning liquid and backflow pollution are avoided, and the smoothness and efficiency of sewage discharge are guaranteed.

[0055] The working principle of the present invention is:

[0056] The cleaning basket 22 is placed in the cleaning chamber 2 and fixed to the rotating frame 31 through the T-shaped clip 221 and the T-shaped groove 311, the cleaning chamber door is closed to ensure the sealing of the cleaning environment, the power is turned on, the one-way valve 16 is closed, and the spray cleaning stage is first entered. The spray pipes 212 on both sides spray cleaning liquid to the cleaning basket 22 in the center for cleaning. At the same time, the rotating motor 33 is started, and the rotating frame 31 is driven to rotate by the driving wheel 32, and then the rotating frame 31 drives the cleaning basket 22 to rotate vertically. During the rotation process, the cleaning basket 22 cooperates with the spray pipes 212 on both sides to form multi-directional cleaning without dead angles. The spray pipe 212 is closed, the spray cleaning is ended, and the immersion cleaning begins. The cleaning solution submerges the cleaning parts. At this time, the double impellers at the bottom rotate in the opposite direction under the rotation of the driving wheel 32 and the driven wheel 35. The double-circular vortex rotates in a spiral around the vortex axis in the cleaning chamber. At the same time, the ultrasonic transducer 13 at the bottom of the box is started, and the high-frequency ultrasonic wave is transmitted to the medium of the cleaning solution, causing the cleaning solution to generate a large number of vacuum bubbles. The vacuum bubbles burst instantly and continuously impact the pollutants attached to the industrial parts. Combined with the double-circular vortex, a coupling cleaning field of mechanical energy and acoustic energy is formed, which increases the turbulent kinetic energy of the flow during the immersion cleaning process, thereby effectively causing the pollutants to fall quickly from the industrial parts. After the immersion cleaning is completed, the one-way valve 16 is opened, and the solution mixed with pollutants is discharged to the drain pipe 15 through the drain port 17 at the bottom. The hot air enters the cleaning area, and the hot air cooperates with the rotating cleaning basket to realize the function of mechanical centrifugal drying, which quickly dries the industrial parts. After drying is completed, the cleaning chamber door is opened and the cleaning basket 22 is taken out.
