[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an ultrasonic multifunctional cleaning device, such as... Figures 1-5 As shown, the system includes a cleaning tank 17, which is welded from stainless steel plates. Several ultrasonic transducer units 8 are installed around the outer surface and bottom of the cleaning tank 17. When a tray is placed inside the cleaning tank, the ultrasonic transducer units 8 generate high-frequency vibrations, which are transmitted to the water inside the cleaning tank 17, thereby forming micro-jet streams. These micro-jet streams remove electrolyte, oil, dust, metal shavings, etc. from various parts of the tray, thus achieving a comprehensive cleaning effect.

[0032] In this embodiment, the ultrasonic transducer unit 8 includes an ultrasonic transducer and an electrical control panel. In the prior art, the ultrasonic transducer includes an ultrasonic transducer and an ultrasonic amplitude transformer. The electrical control panel generates a specific frequency to drive the ultrasonic transducer, which converts electrical energy into mechanical energy and vibrates.

[0033] like Figures 1-5As shown, a drain outlet is provided on the bottom plate of one side of the cleaning tank 17, and a water inlet is provided on the top of the side plate. A drain pipe 13 is provided on the drain outlet and connects to the inside of the water storage tank 12. A water pump 15 is fixedly installed inside the water storage tank. The output port of the water pump is connected to one end of the water inlet pipe 14, and the other end of the water inlet pipe 14 is connected to the water inlet. A valve 18 is installed on the drain pipe 13. When the valve 18 is opened, the sewage in the cleaning tank 17 enters the water storage tank 12. When the valve 18 is closed, the sewage in the cleaning tank 17 cannot enter the water storage tank 12. A filter assembly 16 is provided at the end of the drain pipe 13 located inside the water storage tank to filter the water discharged from the drain pipe 13 into the water storage tank 12. It can be understood that the sewage in the cleaning tank 17 is filtered and then enters the water storage tank 12, and is then pumped back into the cleaning tank 17 by the water pump 15, which can realize the recycling of water resources. The switch of the water pump 15 is located on the outside of one side wall of the water storage tank.

[0034] The cleaning tank 17 is supported and fixed by a column structure and a frame structure. The column structure is fixedly installed at the bottom of the frame structure. The frame structure is composed of several welded rods, specifically including four bottom side rods 4. Among them, multiple bottom long rods 21 are evenly fixed between two opposing bottom side rods 4, and multiple bottom short rods 22 are evenly fixed between the bottom long rods 21 and between the bottom long rods and the bottom side rods. The bottom long rods 21 and the bottom short rods 22 are perpendicular to each other. The bottom long rods 21, bottom short rods 22, and bottom side rods 4 together form the bottom frame of the frame structure, which is used to provide stable and uniform support for the cleaning tank.

[0035] The frame structure also includes four top edge rods 6, which are the same length as the bottom edge rods 4, and the four top edge rods 6 form the top frame. The top frame and the bottom frame are the same shape and size, and the four corners of the top frame and the four corners of the bottom frame are fixedly connected by vertical edge rods 5. Multiple short vertical rods 7 are fixedly connected between the top edge rods 6 and the corresponding bottom edge rods 4.

[0036] It is understandable that the upper part of the frame structure is open, and the interior of the frame structure can just accommodate the cleaning tank. After the cleaning tank is set inside the frame structure, ultrasonic transducer units 8 are then installed on the outer surface and bottom of the cleaning tank. It is also understandable that the ultrasonic transducer units 8 are evenly fixed between the gaps of the various members of the frame structure.

[0037] like Figures 1-5 As shown, the column structure includes four corner columns 1. The bottom of each corner column 1 is welded and fixed with a first connecting plate 2, and the top of each corner column 1 is welded and fixed with a second connecting plate 3. The four second connecting plates 3 are respectively fixedly connected to the four corners of the bottom frame.

[0038] The column structure also includes multiple intermediate columns 9. The bottom of each intermediate column 9 is welded and fixed with a third connecting plate 10, and the top of each intermediate column 9 is welded and fixed with a fourth connecting plate 11. In this embodiment, four intermediate columns 9 are provided, two of which are located in the middle of the bottom of the long side of the bottom frame, and the other two are located near the bottom center of the bottom frame. Specifically, they are located near the bottom of the connection between the bottom short rod 22 and the bottom long rod 21 near the bottom center of the bottom frame.

[0039] By installing connecting plates at the top and bottom of the four corner columns or the middle column, the connection area between the top of the four corner columns or the middle column and the frame structure can be increased, as can the contact area between the bottom of the four corner columns or the middle column and the ground; by increasing the connection area and the contact area, the stability of the connection support can be ensured.

[0040] In this embodiment, all rods, columns, and connecting plates are made of corrosion-resistant galvanized pipes to improve service life. To enhance the cleaning effect of ultrasonic cleaning, the cleaning tank is made of thin-walled stainless steel plate.

[0041] like Figures 1-5 As shown, an electrical control panel 19 is set on the outside of the frame structure. All ultrasonic transducer units 8 are connected to the electrical control panel 19 through ultrasonic transducer connecting lines 20. The electrical control panel 19 controls the opening / closing of the ultrasonic transducer units 8 as well as the vibration frequency and duration.

[0042] The electrical control panel 19 adopts existing technology and mainly includes a housing, main power switch, circuit breaker, transformer, control elements (buttons or switches), indicator lights, relays and contactors, PLC controller, touch screen, instruments, etc. It is understood that this embodiment does not improve the electrical control panel and will not be described further. Figure 6 , Figure 7As shown, the filter assembly 16 includes a tubular outer shell 161, with a filter element 162 disposed at the outlet end of the tubular outer shell 161, and an electro-adsorption assembly 163 disposed in the middle of the tubular outer shell 161. The electro-adsorption assembly 163 includes multiple corrugated electrode adsorption plates 1631, the number of which is even. The electrode adsorption plates 1631 are arranged along the axial direction of the tubular outer shell 161 inside the tubular outer shell 161, with a certain distance between each pair of electrode adsorption plates 1631. Each pair of electrode adsorption plates 1631 is connected to the positive and negative terminals of an electrode adsorption power supply 1632 via electrical wires. It can be understood that the electrode adsorption power supply 1632 is disposed on the outer wall of the tubular outer shell 161, and the electrical wires pass through the sealing element disposed on the outer wall of the tubular outer shell 161 to connect to the electrode adsorption power supply 1632; the corrugation increases the adsorption area. The sealing element adopts the existing technology of elastic frustoconical sleeve plug. The frustoconical sleeve plug has a wire hole in the middle of the axis. A corresponding through hole is opened on the tubular outer shell 161. The diameter of the through hole is smaller than the bottom diameter of the frustoconical sleeve plug and larger than the top diameter of the frustoconical sleeve plug. The wire is passed through the wire hole, and then the frustoconical sleeve plug is plugged into the through hole to achieve a sealing effect.

[0043] Understandably, the inlet end of the tubular housing 161 is connected to the drain pipe 13 via a flange, and the outlet end is also connected to the open end cap via a flange. The opening diameter of the open end cap is smaller than the diameter of the tubular housing 161, thereby preventing the filter element 162 from being flushed out and ensuring water output.

[0044] At the water inlet of the tubular housing 161, a pressure gauge 164 is installed at a position away from the electro-adsorption component 163 of the filter screen. The water pressure of the filter component 16 is monitored by the pressure gauge 164. When the staff observes that the pressure gauge 164 is lower than the set range, it means that the filter element 162 needs to be cleaned or replaced. At this time, the tubular housing 161 is removed from the drain pipe 13, and the filter element 162 is cleaned while the electrode adsorption plate 1631 is also cleaned.

[0045] When the wastewater in the cleaning tank 17 enters the filter assembly through the drainage pipe, the electrode adsorption plate 1631 adsorbs the metal impurities, anions and cations in the wastewater, and the wastewater is finally filtered again through the outlet filter screen.

[0046] Understandably, the pH value of the water in the storage tank is tested at regular intervals, and the water in the equipment is replaced when the acidity or alkalinity of the water exceeds the set range.

[0047] The process flow of this utility model is as follows:

[0048] Place the tray to be cleaned in the cleaning tank and turn on the ultrasonic transducer unit 8 to clean the electrolyte, oil, dust and metal shavings on the surface of the tray.

[0049] After cleaning for a period of time, when the water in the cleaning tank 17 becomes turbid or contains a lot of dust, metal shavings and other foreign objects, open the valve 18 and turn on the electrode adsorption power supply 163 at the same time, so that the sewage flows through the drain pipe 13, is filtered through the filter assembly 16 and enters the water storage tank.

[0050] Turn on the water pump 15 in the water storage tank to pump the filtered water into the cleaning tank 17 through the water inlet pipe 14.

[0051] The pH value of the water in the storage tank is tested at regular intervals. When the acidity or alkalinity of the water exceeds the set range, the water in the equipment is replaced.

[0052] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
