Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically an ultrasonic cleaner. Background Technology

[0002] An ultrasonic cleaner is a device that uses ultrasonic waves to clean items. Patent No. 202211417693.5 discloses an ultrasonic cleaner including a first water tank, a second water tank, and a lifting device. The lifting device connects the first and second water tanks. The first water tank is used for self-circulating cleaning of the items to be cleaned using ultrasonic cleaning agents; the second water tank is used for rinsing the items to be cleaned using ultrasonic cleaning with pure water; the lifting device is used to transfer the items treated in the first water tank to the second water tank for secondary cleaning. However, this dual-tank ultrasonic cleaner requires cleaning in two separate water tanks, which not only reduces cleaning efficiency but also increases the complexity of the equipment. This is especially inconvenient when cleaning larger items (such as the feeding hopper of a food packaging machine) by cleaning them in two separate water tanks. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides an ultrasonic cleaning machine with a more reasonable structure.

[0004] This ultrasonic cleaning machine includes a frame, a cleaning tank, an ultrasonic generator, and a vibrator, with the vibrator located below the cleaning tank. Its features include: a bracket for suspending items to be cleaned within the cleaning tank; a water inlet pipe connected to a water injection control valve on the cleaning tank; a drain pipe connected to a drain valve at the bottom of the cleaning tank; a cleaning fluid pipeline with an injection port installed above the cleaning tank; a cleaning fluid tank mounted on the frame, connected to the cleaning fluid pipeline via a delivery pipeline; a spray pipe with spray heads installed above the cleaning tank, connected to a conveying pipeline; and a spray pipe with spray heads installed above the cleaning tank, connected to the conveying pipeline.

[0005] The delivery pipeline is connected to the outlet of the switching control valve. The switching control valve has two inlets: the first inlet is connected to the water pipeline, and the second inlet is connected to the gas pipeline. The water pipeline is connected to the water booster pump, and the gas pipeline is connected to the blower.

[0006] The conveying pipeline is connected to the steam pipeline, the steam pipeline is connected to the steam generator, and a steam booster pump is connected to the steam pipeline.

[0007] The cleaning tank is equipped with a liquid level detector, which is connected to the control center, which can control the water injection control valve.

[0008] The bracket includes a crossbeam and a suspension plate connected to the crossbeam. The side of the suspension plate has a shaft groove, the inner end of the shaft groove has a downwardly curved extension, and the upper side of the suspension plate has a shaft mounting groove.

[0009] A liquid delivery booster pump is installed on the liquid delivery pipeline.

[0010] The ultrasonic cleaning machine provided by this utility model can complete all cleaning work in one water tank, which significantly improves cleaning efficiency and reduces the difficulty of equipment manufacturing. Attached Figure Description

[0015] Figure 5 This is a schematic diagram of the support structure. Detailed Implementation

[0016] like Figure 1 and Figure 2 As shown, this ultrasonic cleaning machine includes a frame 1, a cleaning tank 2, an ultrasonic generator 4, and a vibrator 3 (the ultrasonic generator drives the vibrator through a high-frequency electrical signal, the vibrator converts electrical energy into mechanical vibration energy, and the vibrating plate of the vibrator generates a cavitation effect through high-frequency vibration, which removes contaminants). The vibrator 3 is located below the cleaning tank 2. The cleaning tank 2 is equipped with a bracket 5 for suspending the objects to be cleaned. The cleaning tank 2 is equipped with a water inlet pipe 20, which is connected to a water injection control valve 22. The lower part of the cleaning tank 2 is equipped with a drain pipe 21, which is connected to a drain valve 23. A cleaning fluid pipe 7 is installed above the cleaning tank 2, and the cleaning fluid pipe 7 is equipped with a liquid injection port 70. A cleaning fluid tank 18 is installed on the frame 1, and the cleaning fluid tank 18 is connected to the cleaning fluid pipe 7 through a liquid delivery pipe 17. Figure 2 and Figure 4 As shown, a spray pipe 9 is installed above the cleaning tank 2, and a spray head 90 is provided on the spray pipe 9. The spray pipe 9 is connected to the conveying pipe 8.

[0017] The working principle of this ultrasonic cleaner is as follows: The object to be cleaned is suspended on the bracket 5, and then the water injection control valve 22 is opened, and clean water flows into the cleaning tank 2 through the water inlet pipe 20; at the same time, the cleaning liquid in the cleaning liquid tank 18 is delivered to the cleaning liquid pipe 7 through the liquid delivery pipe 17, and the liquid injection port 70 on the cleaning liquid pipe 7 injects the cleaning liquid into the cleaning tank 2. When the water in the cleaning tank 2 reaches a certain height, the water injection control valve 22 is closed; then, the vibrator 3 vibrates to perform ultrasonic cleaning on the object to be cleaned in the cleaning tank 2; after the ultrasonic cleaning is completed, the drain valve 23 is opened to allow the sewage to be discharged through the drain pipe 21; after the sewage is discharged, the water in the delivery pipe 8 flows into the spray pipe 9, the spray pipe 9 is filled with water, and the clean water is sprayed through the spray head 90 to clean the object to be cleaned, rinsing away the residual dirt and water stains on the object to be cleaned.

[0018] After the items are rinsed clean, they still retain moisture. To dry the items, the conveying pipe 8 is connected to the outlet of the switching control valve 10, such as... Figure 3 As shown, the switching control valve 10 has two inlets. The first inlet is connected to the water supply pipe 11, and the second inlet is connected to the air supply pipe 13. The water supply pipe 11 is connected to the water booster pump 12, and the air supply pipe 13 is connected to the fan 14. When it is necessary to rinse the items to be washed with clean water, the switching control valve 10 switches the delivery pipe 8 to be connected to the water supply pipe 11. The water booster pump 12 pumps clean water through the water supply pipe 11 into the delivery pipe 8. The clean water then flows through the delivery pipe 8 into the spray pipe 9, where the spray nozzles 90 spray and clean the items to be washed. After the items to be washed have been sprayed and cleaned, the switching control valve 10 switches the delivery pipe 8 to be connected to the air supply pipe 13. The fan 14 introduces air into the air supply pipe 13. The air then flows through the air supply pipe 13 into the delivery pipe 8, and then into the spray pipe 9. The spray nozzles 90 on the spray pipe 9 blow air onto the items to be washed, drying them.

[0019] To enable steam sterilization of the items to be washed, the conveying pipe 8 is connected to a steam pipe, which in turn is connected to a steam generator. A steam booster pump is connected to the steam pipe. When it is necessary to sterilize the items, the steam generator produces steam, which is then pumped into the steam pipe by the steam booster pump. The steam then enters the conveying pipe 8 and flows into the spray pipe 9. The spray nozzles 90 on the spray pipe 9 spray steam onto the items to be washed, thus achieving steam sterilization.

[0020] like Figure 2As shown, a liquid level detector 28 is installed in the cleaning tank 2. The liquid level detector 28 is connected to the control center (PLC control system), which can control the water injection control valve 22 to operate. When the liquid level detector 28 detects that the liquid level has reached the set height, the liquid level detector 28 transmits a signal to the control center, which then controls the water injection control valve 22 to close, so that water no longer enters the cleaning tank 2.

[0021] like Figure 5 As shown, the support 5 includes a crossbeam 50 and a suspension plate 51 connected to the crossbeam 50. The side of the suspension plate 51 has a shaft groove 52, and the inner end of the shaft groove 52 has a downwardly curved extension section 53. The upper side of the suspension plate 51 has a hanging shaft groove 54. Generally, the feeding hopper of a food packaging machine has multiple connecting shafts. When feeding the hopper, only one connecting shaft needs to be placed in the shaft groove 52 and then slid into the extension section 53. Since the extension section 53 is bent downward, the connecting shaft is stuck in the extension section 53. Then, the other connecting shaft of the feeding hopper is inserted into the hanging shaft groove 54 above. In this way, the feeding hopper is hung on the suspension plate 51 for cleaning. This structure of the suspension plate 51 makes it very convenient to hang and remove the feeding hopper.

[0022] Finally, it is worth mentioning that a liquid delivery booster pump 16 is installed on the liquid delivery pipe 17. This booster pump 16 can pump the cleaning fluid from the cleaning fluid tank 18 into the cleaning fluid pipe 7. Of course, the cleaning fluid tank 18 can also be hung at a high place, allowing the cleaning fluid to flow into the cleaning fluid pipe 7 by gravity.
