Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning machine technology, and in particular to an ultrasonic circulating cleaning machine with a sewage filtration mechanism. Background Technology

[0002] Ultrasonic cleaning machines convert the acoustic energy of a high-power ultrasonic source into mechanical vibration through a transducer, and then radiate the ultrasonic waves through the walls of the cleaning tank into the cleaning fluid. Microbubbles in the liquid vibrate under the influence of the sound waves, disrupting the adhesion between dirt and the surface of the parts being cleaned, causing fatigue damage and peeling off the dirt layer. The enormous pressure generated by this ultrasonic cavitation can break down insoluble dirt, causing it to decompose in the solution. Simultaneously, the jets generated as the ultrasound propagates in the cleaning fluid also assist in impacting the parts being cleaned, achieving the cleaning purpose.

[0003] In existing ultrasonic cleaning machines, solid contaminants that detach from the workpiece surface directly mix into the cleaning solution during the cleaning process, causing the cleaning solution to be quickly contaminated. As the cleaning time increases, the concentration of suspended solid contaminants in the contaminated cleaning solution gradually increases, which not only reduces the cleanliness of subsequent cleaning but also causes the workpiece surface to be re-attached by suspended contaminants in the cleaning solution, forming secondary pollution, which seriously affects the cleaning quality and efficiency.

[0004] Therefore, an ultrasonic circulating cleaning machine with a sewage filtration mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that as the cleaning time increases, the concentration of suspended solid pollutants in the contaminated cleaning solution gradually increases, which not only reduces the cleanliness of subsequent cleaning but also causes the suspended pollutants in the cleaning solution to re-attach to the workpiece surface, resulting in secondary pollution. Therefore, this invention proposes an ultrasonic circulating cleaning machine with a wastewater filtration mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic circulating cleaning machine with a sewage filtration mechanism, comprising a cleaning tank, a controller fixedly mounted on the outer wall of the cleaning tank, a plurality of ultrasonic transducers fixedly mounted on the lower surface of the cleaning tank, a first solenoid valve tube fixedly mounted on the lower surface of the cleaning tank, a filter frame fixedly mounted on the lower surface of the cleaning tank, the filter frame being fixedly connected to the first solenoid valve tube, a water pump fixedly connected to the outer wall of the filter frame, a third solenoid valve tube fixedly connected to the inlet end of the water pump, the third solenoid valve tube being fixedly connected to the filter frame, a second solenoid valve tube fixedly connected to the lower surface of the filter frame, a drain pipe fixedly connected to the outlet end of the water pump, a sealing frame slidably connected to the inner wall of the filter frame, a filter plate fixedly mounted on the inner wall of the sealing frame, and a pull plate slidably connected to the filter frame fixedly mounted on the outer wall of the sealing frame.

[0007] The effect achieved by the above components is as follows: by setting up filter plates, the secondary pollution caused by solid contaminants is effectively avoided during the cleaning process of the workpiece through the circulation and filtration of the cleaning fluid, while improving the utilization rate of the cleaning fluid and the cleaning efficiency.

[0008] Preferably, the inner wall of the cleaning tank is fixedly equipped with an electric heating tube and a temperature sensor, and the electric heating tube, temperature sensor, ultrasonic transducer, first solenoid valve tube, second solenoid valve tube, third solenoid valve tube and water pump are all electrically connected to the controller.

[0009] The above components achieve the following effects: by setting up an electric heating element and a temperature sensor, the electric heating element can heat the cleaning solution in the cleaning tank when it is turned on, and the temperature sensor monitors the temperature of the cleaning solution in real time and feeds the data back to the controller to ensure that the temperature is maintained within the set range to ensure the cleaning effect.

[0010] Preferably, the cross-section of the filter plate is wavy.

[0011] The effect achieved by the above components is that the filter plate with a vertical cross-section in the shape of a wave can efficiently intercept suspended solid pollutants due to its larger filtration area.

[0012] Preferably, a round rod is fixedly mounted on the outer wall of the filter frame, and a rotating plate is rotatably connected to the circumferential surface of the round rod, with the rotating plate abutting against the surface of the pull plate.

[0013] The effect achieved by the above components is that the rotating plate can limit the position of the sealing frame, thereby limiting the position of the filter plate.

[0014] Preferably, a torsion spring is fitted around the circumference of the round rod, and the two ends of the torsion spring are fixedly connected to the rotating plate and the round rod, respectively.

[0015] The effect achieved by the above components is that when the torsion spring is torn, it can use its own torque to drive the rotating plate to reset.

[0016] Preferably, a protective ring is fixedly mounted on the surface of the rotating plate, the torsion spring is located inside the protective ring, and a plurality of anti-slip grooves are formed on the outer circumferential surface of the protective ring.

[0017] The effect achieved by the above components is as follows: when the protective ring is rotated, the protective ring will drive the rotating plate to rotate. At this time, the anti-slip groove can increase the friction of the outer circumference of the protective ring, and the protective ring can shield and protect the torsion spring.

[0018] Preferably, a stop block is fixedly mounted on the surface of the pull plate, and the rotating plate abuts against the circumferential surface of the stop block.

[0019] The effect achieved by the above components is that the stop block can limit the rotation range of the rotating plate and prevent the rotating plate from losing contact with the pull plate due to excessive rotation caused by the torsion spring torque.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a filter plate, the cleaning fluid is circulated and filtered during the cleaning process of the workpiece, which effectively avoids secondary pollution caused by solid contaminants, and at the same time improves the utilization rate of the cleaning fluid and the cleaning efficiency.

[0021] In this invention, by setting an electric heating element and a temperature sensor, the electric heating element can heat the cleaning liquid in the cleaning tank when it is turned on, and the temperature sensor monitors the temperature of the cleaning liquid in real time and feeds the data back to the controller to ensure that the temperature is maintained within the set range to ensure the cleaning effect.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-5As shown, this utility model provides an ultrasonic circulating cleaning machine with a sewage filtration mechanism, including a cleaning tank 1. A controller 4 is fixedly mounted on the outer wall of the cleaning tank 1. Several ultrasonic transducers 5 are fixedly mounted on the lower surface of the cleaning tank 1. A first solenoid valve tube 6 is fixedly mounted on the lower surface of the cleaning tank 1. A filter frame 7 is fixedly mounted on the lower surface of the cleaning tank 1. The filter frame 7 is fixedly connected to the first solenoid valve tube 6. A water pump 9 is fixedly connected to the outer wall of the filter frame 7. A third solenoid valve tube 10 is fixedly connected to the inlet end of the water pump 9. The filter is fixedly connected to the filter frame 7, and the lower surface of the filter frame 7 is fixedly connected to the second solenoid valve pipe 8. The drain end of the water pump 9 is fixedly connected to the drain pipe 11. The inner wall of the filter frame 7 is slidably connected to the sealing frame 12. The inner wall of the sealing frame 12 is fixedly fitted with the filter plate 13. The outer wall of the sealing frame 12 is fixedly fitted with the pull plate 14 that is slidably connected to the filter frame 7. By setting the filter plate 13, when cleaning the workpiece, the secondary pollution caused by solid contaminants is effectively avoided through the circulation filtration of the cleaning liquid, while improving the utilization rate of the cleaning liquid and the cleaning efficiency.

[0027] like Figure 1 As shown, an electric heating element 2 and a temperature sensor 3 are fixedly installed on the inner wall of the cleaning tank 1. The electric heating element 2, the temperature sensor 3, the ultrasonic transducer 5, the first solenoid valve tube 6, the second solenoid valve tube 8, the third solenoid valve tube 10, and the water pump 9 are all electrically connected to the controller 4. By setting the electric heating element 2 and the temperature sensor 3, the electric heating element 2 can heat the cleaning liquid in the cleaning tank 1 when it is activated. The temperature sensor 3 monitors the temperature of the cleaning liquid in real time and feeds the data back to the controller 4 to ensure that the temperature is maintained within the set range to ensure the cleaning effect.

[0028] like Figures 3-5 As shown, the cross-section of the filter plate 13 is wavy. The wavy vertical cross-section of the filter plate 13 can efficiently intercept suspended solid pollutants due to its larger filtration area. A round rod 15 is fixedly mounted on the outer wall of the filter frame 7. A rotating plate 16 is rotatably connected to the circumferential surface of the round rod 15. The rotating plate 16 abuts against the surface of the pull plate 14. The rotating plate 16 can limit the position of the sealing frame 12, thereby limiting the position of the filter plate 13. A torsion spring 17 is sleeved on the circumferential surface of the round rod 15. The two ends of the torsion spring 17 are fixedly connected to the rotating plate 16 and the round rod 15 respectively. When the torsion spring 17 is twisted, it can drive the rotating plate 16 to reset by its own torque.

[0029] like Figures 3-5As shown, a protective ring 18 is fixedly mounted on the surface of the rotating plate 16, and a torsion spring 17 is located inside the protective ring 18. Several anti-slip grooves 19 are provided on the outer circumferential surface of the protective ring 18. When the protective ring 18 is rotated, the protective ring 18 will drive the rotating plate 16 to rotate. At this time, the anti-slip grooves 19 can increase the friction of the outer circumferential surface of the protective ring 18. The protective ring 18 can shield and protect the torsion spring 17. A stop block 20 is fixedly mounted on the surface of the pull plate 14. The rotating plate 16 abuts against the circumferential surface of the stop block 20. The stop block 20 can limit the rotation range of the rotating plate 16 and prevent the rotating plate 16 from disengaging from the pull plate 14 due to excessive rotation caused by the torque of the torsion spring 17.

[0030] The overall working principle is as follows: when cleaning the workpiece, the workpiece is suspended in the cleaning liquid by an external suspension frame. Then, the controller 4 controls the electric heating tube 2 to start heating the cleaning liquid in the cleaning tank 1. The temperature sensor 3 monitors the temperature of the cleaning liquid in real time and feeds the data back to the controller 4 to ensure that the temperature is maintained within the set range to ensure the cleaning effect. Subsequently, the ultrasonic transducer 5 is activated, converting sound energy into mechanical vibration and transmitting it to the cleaning liquid in the cleaning tank 1, causing a large number of microbubbles to form in the liquid. The microbubbles vibrate continuously under the action of ultrasonic waves and produce cavitation effect. The instantaneous high-pressure shock wave destroys the adsorption relationship between the dirt and the surface of the workpiece, causing the dirt layer to peel off and achieving comprehensive cleaning of the workpiece.

[0031] During the cleaning process, solid contaminants detached from the workpiece surface flow into the filter frame 7 along with the cleaning fluid through the opened first solenoid valve 6. The vertically corrugated filter plate 13, with its larger filtration area, can efficiently intercept suspended solid contaminants, preventing them from re-mixing into the cleaning fluid. At this time, the water pump 9 starts and the third solenoid valve 10 opens. The clean cleaning fluid filtered by the filter plate 13 is drawn by the water pump 9 and returned to the cleaning tank 1 through the drain pipe 11, forming a recycling of the cleaning fluid. When it is necessary to clean the contaminants intercepted on the filter plate 13, the first solenoid valve 6, the third solenoid valve 10, and the water pump 9 can be closed. Rotating the protective ring 18 causes the rotating plate 16 to rotate, disengaging it from the stop 20 on the pull plate 14. At this time, the anti-slip groove 19 increases the friction on the outer circumference of the protective ring 18, and the protective ring 18 protects the torsion spring 17. Then, pulling the pull plate 14 allows the sealing frame 12, along with the filter plate 13, to be pulled out of the filter frame 7 for cleaning. After cleaning, the sealing frame 12 is reset, the rotating plate 16 is released, and the torsion spring 17 causes the rotating plate 16 to reset and press against the stop 20, thus securing the sealing frame 12 firmly. The second solenoid valve 8 can be opened when waste liquid needs to be discharged, draining the waste liquid from the cleaning tank 1 and the filter frame 7. Through the circulating filtration of the cleaning fluid, secondary pollution caused by solid contaminants is effectively avoided, while simultaneously improving the utilization rate and cleaning efficiency of the cleaning fluid.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
