Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and in particular to an ultrasonic cleaning tank and cleaning machine. Background Technology

[0002] An ultrasonic cleaner is a device that uses the physical cleaning principle of ultrasonic waves. It generates thousands of tiny bubbles through vibration, which can peel off, remove, and emulsify dirt such as dust and fingerprints attached to the surface of a glass cover, achieving a highly clean cleaning effect.

[0003] Chinese patent publication number CN112387692A discloses a silicon wafer cleaning tank, relating to the field of silicon wafer production technology. Specifically, it describes a silicon wafer cleaning tank comprising a tank body, an ultrasonic generator fixedly mounted on the top of the tank body, a drain outlet fixedly connected to the right side of the tank body, a control valve fixedly mounted on the top of the drain outlet, a baffle fixedly connected inside the tank body, a silicon wafer placement plate placed on top of the baffle, a slot provided on the top of the silicon wafer placement plate, and a side plate fixedly connected to the right side of the top of the silicon wafer placement plate. This silicon wafer cleaning tank uses a high-pressure nozzle to create a high-pressure water jet to rinse the silicon wafers, effectively removing adhering substances from the wafer surface. When the rinsing water flows over the top of the silicon wafers, the ultrasonic waves generated by the ultrasonic generator vibrate the cleaning water, performing a secondary cleaning of the silicon wafers, thus improving cleaning efficiency. However, there are many dead zones in the corners and other areas of the tank body, making it difficult for floating dirt to flow out of the tank through the drain outlet, causing dirt to accumulate in the tank body and reducing the cleaning performance of the cleaning tank.

[0004] Chinese patent publication number CN105214995A discloses an ultrasonic cleaning tank for glass, including a cleaning tank and a filter device. The cleaning tank contains a filter device with stepped grooves along its top perimeter. The filter device is a mesh cuboid structure containing multiple parallel filter screens spaced equidistantly, forming multiple filter compartments. Each filter compartment can hold a piece of glass, separating the glass pieces to be cleaned. At least two supporting convex shafts extending into the stepped grooves are provided laterally on both sides of the filter device, allowing it to be suspended in the cleaning tank. The filter screens are made of graphite. This invention effectively prevents waste from dissolving into the cleaning agent, ensuring the cleaning agent remains clean and uncontaminated. Multiple pieces of glass can be cleaned simultaneously without interference. Graphite is lightweight, corrosion-resistant, and has a long service life. However, multiple filters create too many dead zones within the cleaning tank, causing dirt to accumulate. Excessive accumulation can lead to secondary contamination of the cleaned glass, resulting in poor cleaning performance. Summary of the Invention

[0005] To address the problem of dirt accumulation and difficulty in flowing out of the cleaning tank, this application provides an ultrasonic cleaning tank and cleaning machine.

[0006] Firstly, the ultrasonic cleaning tank provided in this application adopts the following technical solution:

[0007] A support groove with serrated edges is provided for placing cleaning fixtures.

[0008] An ultrasonic cleaner is installed inside the support tank;

[0009] An overflow trough surrounds the serrated edge to allow low-density contaminants floating on the surface of the carrying trough to overflow evenly into the overflow trough;

[0010] An overflow device, installed in the bearing tank, is used to accelerate the overflow of low-density dirt on the cleaning fixture from the bearing tank into the overflow tank.

[0011] By adopting the above technical solution, the cleaning fixture is placed in the carrier tank, and water or cleaning fluid is introduced. Ultrasonic waves generated by an ultrasonic cleaner are used to clean the items inside the cleaning fixture. During the cleaning process, oil, dust, and other contaminants on the items inside the cleaning fixture will fall off and float to the upper liquid surface of the carrier tank. An overflow trough is provided around the edge of the carrier tank, allowing the contaminants floating on the upper liquid surface of the carrier tank to overflow from the carrier tank and enter the overflow trough under the push of the overflow device. The connecting edge between the overflow trough and the carrier tank is a serrated edge. The serrated edge can provide a certain overflow resistance in the case of excessive overflow, so that the liquid in the carrier tank can overflow evenly, avoiding excessive liquid overflow in one direction during the overflow process, which would cause the liquid to splash out of the overflow trough. This allows the liquid and contaminants to be stably collected by the overflow trough. By using the overflow method to discharge contaminants, it is possible to prevent contaminants from accumulating in the carrier tank, ensuring the cleanliness of the cleaning tank after long-term use and maintaining the cleaning performance.

[0012] Optionally, the overflow device includes a bubble generator, which is located at the bottom of the support tank and is capable of generating bubbles.

[0013] By adopting the above technical solution and using a bubble machine as an overflow device, after the ultrasonic cleaner completes the cleaning, low-density dirt floats to the surface of the liquid. As the liquid gradually increases, the liquid on the surface overflows the carrying tank. The bubbles generated by the bubble machine push the floating dirt to the edge, so that the dirt can overflow the carrying tank more quickly with the liquid. After the cleaning fixture is cleaned, the rapid overflow of dirt can prevent the cleaning fixture from coming into contact with dirt again during the removal of the carrying tank, thus ensuring the cleaning effect while achieving efficient cleaning.

[0014] Optionally, the overflow device further includes a centrifugal device installed in the support tank to cause the liquid in the support tank to flow in a vortex. The centrifugal device includes a fixed part, a rotating part, and blades. The fixed part is installed on the inner wall of the support tank. The rotating part is connected to the fixed part and can rotate relative to the fixed part. The blades are installed on the rotating part to agitate the liquid to form a vortex flow, thereby aggregating the bubbles generated by the bubble generator.

[0015] By adopting the above technical solution, the centrifugal device can make the liquid in the carrying tank form a vortex flow. In the vortex flow, the less dense part of the liquid will gather in the middle of the vortex, and the more dense part will disperse to the outside of the vortex. The rotating part can rotate relative to the fixed part to provide power for the formation of the vortex flow. The blades can amplify the effect of the rotating part on the liquid, enabling the centrifugal device to form a vortex flow more quickly and increase the flow rate of the vortex flow. Because of their low density, bubbles tend to gather in the center of a swirling liquid and rise to the surface. However, since the cleaning fixture is placed in the center of the tank, the upward-rising bubbles are blocked and cannot maintain their position in the center to reach the surface. Placing a bubble generator above the cleaning fixture would also hinder its placement and removal. Therefore, a centrifugal device is used to gather the bubbles in the center as they pass through the cleaning fixture, allowing the floating dirt to be pushed from the center to the edge. As the liquid level rises, it overflows from the edge of the tank, making it easier for the dirt gathered at the edge to escape. This allows for faster removal of dirt from the liquid surface. After cleaning, the surface dirt is quickly rinsed off to prevent the cleaning fixture from re-adhering to the cleaned dirt when it is removed. Meanwhile, the vortex-like flow created by the centrifugal device concentrates air bubbles in the center of the tank, causing them to impact the cleaning fixtures. This impact dislodges contaminants that remain after ultrasonic cleaning, and the bubbles accelerate the rising of low-density contaminants, allowing for faster removal. This improves the cleaning capacity and removal speed of the tank, thus increasing its cleaning efficiency. Furthermore, the vortex-like flow also centrifuges high-density contaminants to the edge of the liquid, separating them from the cleaning fixtures. This prevents the fixtures from re-adhering with high-density contaminants during removal after cleaning, further enhancing the tank's cleaning performance.

[0016] Optionally, the centrifugal device is installed near the location where the cleaning tool is being cleaned.

[0017] By adopting the above technical solution, after the bubbles are generated by the bubble generator at the bottom of the support tank, they rise randomly and gather in the middle after passing through the vortex flow formed by the centrifugal device. Since an ultrasonic cleaner is also installed in the support tank, the ultrasonic cleaner will hinder the rise of the bubbles, thus allowing the bubbles to rise freely. After passing the ultrasonic cleaner, the bubbles gather in the middle of the support tank after passing through the centrifugal device near the cleaning fixture, so that the bubbles can rise from the middle to the liquid surface without obstruction.

[0018] Optionally, the centrifuge device further includes a first waste screen, which is disposed inside the rotating part and is used to collect high-density waste.

[0019] By adopting the above technical solution, in the vortex flow formed by the centrifugal device, high-density dirt will disperse to the outside of the vortex liquid due to the centrifugal effect, as the centrifugal force cannot maintain the vortex flow during the liquid flow. Therefore, a first dirt net is provided on the inner side of the rotating part. When high-density dirt surges to the first dirt net on the rotating part under the action of centrifugal force, the first dirt net can entangle the dirt, thereby preventing high-density dirt from re-entering the liquid and improving the cleaning performance of the cleaning tank.

[0020] Optionally, the carrying tank includes an inlet and an outlet. The inlet is located on the side wall of the carrying tank, and the outlet is located on the bottom surface of the carrying tank. A second waste screen is provided inside the outlet for collecting waste.

[0021] By adopting the above technical solution, the inlet is used to add water or cleaning fluid into the carrying tank. Since the inlet needs to continuously add liquid into the carrying tank during the overflow process, its location on the side wall reduces the pressure that needs to be overcome when the tank is full. The outlet is located on the bottom surface, which can completely empty the liquid in the carrying tank. A second sludge screen is provided in the outlet to collect sludge from the liquid during discharge.

[0022] Optionally, the liquid outlet is located at the edge of the bottom of the support tank.

[0023] By adopting the above technical solution, since the centrifuge device will centrifuge high-density dirt to the edge of the carrying tank, the high-density dirt that does not enter the first dirt screen will fall into the corner of the bottom edge of the carrying tank, making it difficult to clean. Therefore, the liquid outlet is set at the bottom edge of the carrying tank, so that during the liquid discharge process, the dirt at the bottom edge can be washed into the second dirt screen, avoiding the accumulation of dirt in the carrying tank.

[0024] Optionally, the overflow trough includes an overflow port for collecting low-density dirt within the overflow trough.

[0025] By adopting the above technical solution, the overflow trough is used to collect low-density dirt floating on the liquid surface. The overflow trough collects the overflowing dirt from the surrounding area of ​​the carrying tank, and the dirt in the overflow trough is collected through the overflow port, so that low-density dirt can be easily collected and treated.

[0026] Secondly, the method of using an ultrasonic cleaning tank provided in this application adopts the following technical solution:

[0027] A method of using an ultrasonic cleaning tank, comprising the following steps:

[0028] S1, Place the cleaning tool into the bearing tank and turn on the ultrasonic cleaner for cleaning;

[0029] S2, activate the overflow device to push the liquid in the upper layer of the carrying tank to overflow into the overflow tank;

[0030] S3. After cleaning is completed, turn off the ultrasonic cleaner, keep the overflow device open, remove the cleaning fixture, and turn off the overflow device after the cleaning fixture is removed.

[0031] By adopting the above technical solution, after the ultrasonic cleaning machine starts, the dirt begins to detach from the items carried in the cleaning fixture. At this time, the overflow device is turned on, allowing the low-density dirt that has detached from the items in the cleaning fixture to overflow into the overflow tank at an accelerated rate. After cleaning is completed, the overflow device is kept on so that the cleaning fixture will not re-adhere to dirt during the removal process, thereby ensuring a better cleaning effect in the cleaning tank. After the cleaning fixture is removed, the overflow device is turned off, thus completing the cleaning process.

[0032] Thirdly, this application provides a cleaning machine that uses the aforementioned ultrasonic cleaning tank.

[0033] By adopting the above technical solution and using the above cleaning tank, the cleaning machine can achieve better cleaning effect. At the same time, because the cleaning tank can quickly discharge the dirt generated during cleaning, it can prevent the cleaning jig from re-adhering the dirt accumulated in the cleaning tank while quickly replacing the cleaning jig.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By providing an overflow trough around the edge of the carrying tank, the dirt floating on the upper liquid surface of the carrying tank is pushed out of the carrying tank by the overflow device and enters the overflow trough. The connecting edge between the overflow trough and the carrying tank is a serrated edge. The serrated edge allows the liquid in the carrying tank to overflow evenly, preventing the liquid from splashing out of the overflow trough. The dirt is discharged by overflow, which can prevent the dirt from accumulating in the carrying tank and ensure the cleanliness of the cleaning tank after long-term use, so as to maintain the cleaning performance.

[0036] 2. The overflow device includes a bubble generator and a centrifugal device. Due to the low density of the bubbles, the bubbles generated by the bubble generator can be gathered in the middle of the liquid by the vortex flow generated by the centrifugal device during the rising process. The bubbles rise from the middle of the carrying tank to the liquid surface, which pushes the dirt floating on the liquid surface from the middle to the edge and accelerates the floating of low-density dirt, thereby speeding up the discharge of low-density dirt from the carrying tank.

[0037] 3. Within the vortex-like flow formed by the centrifugal device, high-density contaminants will be thrown to the outside of the vortex-like liquid under the influence of centrifugal force as the liquid flows. A first contaminant net is provided on the inner side of the rotating part to trap the contaminants thrown to the outside, thereby preventing high-density contaminants from re-entering the liquid. By using the centrifugal device to gather air bubbles in the middle, low-density contaminants are accelerated to be discharged, while high-density contaminants are collected on the outside, so that contaminants of different densities can be quickly separated from the liquid in the carrying tank.

[0043] The following will provide a more detailed description of this application.

[0044] Example 1: Refer to Figure 1 and Figure 2According to one embodiment of this application, an ultrasonic cleaning tank includes a support tank 1, an ultrasonic cleaner 2, an overflow tank 3, and an overflow device 4. The support tank 1 is the main structure of the cleaning tank and is used to support the cleaning fixtures to be cleaned. The ultrasonic cleaner 2 is detachably installed in the support tank 1 and is used to generate ultrasonic waves to clean the cleaning fixtures under the action of water or cleaning liquid. The detachable ultrasonic cleaner 2 can be removed for replacement or repair at any time, which is convenient for maintenance. Various fixing structures or support structures can be provided in the support tank 1 to fix the cleaning fixtures. In this embodiment, the ultrasonic cleaner 2 is located at the bottom of the support tank 1. After the cleaning fixtures enter the support tank 1, they are placed on top of the ultrasonic cleaner 2. The ultrasonic cleaner 2 supports the cleaning fixtures, so that the ultrasonic waves generated by the ultrasonic cleaner 2 can better act on the cleaning fixtures.

[0045] Reference Figure 2 The support tank 1 is equipped with a slag removal port 15 and a heating rod 16 near the bottom. The slag removal port 15 facilitates the cleaning of dirt deposited at the bottom of the support tank 1, and the heating rod 16 maintains the temperature of the cleaning medium in the support tank 1. An overflow device 4 is located at the bottom of the support tank 1, which can add water, cleaning fluid, and other cleaning media into the support tank 1. The edge of the support tank 1 is a serrated edge 11, and an overflow tank 3 surrounds the outside of the serrated edge 11. After the ultrasonic cleaner 2 completes cleaning, the cleaning medium can be added through the overflow device 4, causing the liquid in the support tank 1 to overflow from the gaps in the serrated edge 11, and carrying the low-density dirt floating on the liquid surface out of the support tank 1 and into the overflow tank 3. This prevents dirt from accumulating in corners and other dead flow areas in the overflow tank 3, which helps to ensure the cleaning performance of the cleaning tank after long-term use. The serrated edge 11 can provide a certain obstruction when the liquid overflows, preventing the liquid from overflowing in large quantities from one direction, thereby ensuring that the liquid overflows evenly at the edge of the bearing tank 1 and preventing the liquid from entering the overflow tank 3 in large quantities from one direction, causing the liquid to splash out from the overflow tank 3.

[0046] Reference Figure 1 and Figure 3 The overflow tank 3 is provided with an overflow port 31. The overflow port 31 is connected to the outside from the opening at the bottom of the overflow tank 3, so that the liquid in the overflow tank 3 can carry low-density dirt such as oil and dust out of the overflow port 31.

[0047] The implementation principle of this application embodiment is as follows: The ultrasonic cleaner 2 is placed in the carrier tank 1, and a cleaning medium is added to the carrier tank 1. At the start of cleaning, the cleaning fixture is placed in the carrier tank 1, and the ultrasonic cleaner 2 is turned on for cleaning. During the cleaning process, the cleaning medium is continuously added from the overflow device 4, causing the liquid in the carrier tank 1 to overflow from the serrated edge 11, thereby causing the dirt on the liquid surface to overflow into the overflow tank 3. Through the overflow tank 3 and the serrated edge 11, the dirt floating on the liquid surface can be collected stably and without dead angles, which is beneficial to ensuring the cleaning performance of the cleaning tank.

[0048] Example 2: Refer to Figure 4 Another embodiment provided in this application is an ultrasonic cleaning tank, which differs from embodiment 1 in that the overflow device 4 includes a bubble generator 41 and a centrifugal device 42. The bubble generator 41 is located at the bottom of the support tank 1 and below the ultrasonic cleaner 2. Since the ultrasonic cleaner 2 is located above the bubble generator 41, the bubble generator 41 generates bubbles from the side. The centrifugal device 42 is installed on the inner wall of the support tank 1, and its installation height is above the ultrasonic cleaner 2, so that the centrifugal device 42 can function at the storage height of the cleaning fixture. The centrifugal device 42 includes a fixed part 42a, a rotating part 42b, blades 42c, and a first dirt screen 42d. The fixed part 42a is installed on the side wall of the support tank 1 and has an annular hollow structure for the annular rotating part 42b to rotate within the fixed part 42a. The blades 42c are fixed on the rotating part 42b and are used to agitate the cleaning medium when the rotating part 42b rotates, so that the liquid forms a vortex flow. In the vortex flow, the bubbles generated by the bubble generator 41, due to their low density, are gathered in the middle of the carrying tank 1 by the vortex flow. During the bubble gathering process, the bubbles will impact the cleaning fixture, which helps the loosened dirt after ultrasonic cleaning to detach from the cleaning items. Substances with a density lower than the cleaning medium after ultrasonic cleaning, such as oil and dust, will gather in the middle with the bubbles and rise with them, accelerating the floating speed of low-density dirt. Substances with a density higher than the cleaning medium that fall off after ultrasonic cleaning will disperse to the edge of the vortex flow. The first dirt net 42d is located inside the rotating part 42b. When high-density dirt disperses to the edge of the vortex flow, the first dirt net 42d can trap the dirt, thereby preventing the dirt from re-entering the cleaning medium and improving the cleaning performance of the cleaning tank.

[0049] Reference Figure 4The carrier tank 1 also includes an inlet 12 and an outlet 13. The inlet 12 is installed on the side wall of the carrier tank 1, and its installation height is higher than that of the centrifuge device 42. It is used to add cleaning medium into the carrier tank 1. The bubble machine 41 and the centrifuge device 42 can only limit low-density dirt to the edge area of ​​the liquid surface through bubbles. The inlet 12 needs to add cleaning medium to the carrier tank 1 to make the liquid surface overflow. By setting the inlet 12 above the centrifuge device 42, the inlet 12 is prevented from being backflowed by the liquid generated when the centrifuge device 42 stirs the cleaning medium when it overflows, and the resistance encountered when adding cleaning medium is reduced. The outlet 13 is located at the edge of the bottom surface of the carrying tank 1, and a second dirt screen 14 is provided inside the outlet 13. Since high-density dirt will be dispersed at the edge with the vortex, and some high-density dirt will not be collected by the first dirt screen 42d, it will sink to the bottom surface when the cleaning tank is in the working interval. The outlet 13 located at the edge can make the high-density dirt at the edge sink onto the second dirt screen 14, so that the cleaning tank can better collect and discharge the dirt generated during cleaning.

[0050] The implementation principle of this application embodiment is as follows: In vortex flow, under the action of centrifugal phenomenon, the substances in the liquid are more concentrated in the middle of the vortex flow due to the centrifugal force of the liquid being greater than the centrifugal force required to maintain the vortex flow. The substances are less concentrated in the middle of the vortex flow due to the centrifugal force of the liquid being less than the centrifugal force required to maintain the vortex flow. The substances are less concentrated in the middle of the vortex flow due to the lower density of the bubbles. The substances generated after ultrasonic cleaning that are less concentrated than the cleaning medium, such as oil and dust, will be concentrated in the middle of the vortex flow with the bubbles and rise with the bubbles, which will accelerate the rising speed of the low-density contaminants. When floating on the liquid surface, the low-density contaminants are pushed to the edge of the bearing tank 1 by the bubbles emerging from the middle, which makes it easier for them to overflow from the bearing tank 1 with the liquid surface and enter the overflow tank 3. After ultrasonic cleaning, high-density contaminants with a density higher than the cleaning medium are dispersed to the edge of the vortex flow under centrifugal force and collected by the first contaminant mesh 42d. The remaining high-density contaminants settle at the edge of the carrying tank 1 and are collected by the second contaminant mesh 14. By separately collecting and treating the lighter low-density contaminants and the heavier high-density contaminants, the cleaning tank can remain clean during continuous cleaning without frequent replacement of the cleaning medium, thus improving the cleaning efficiency of the cleaning tank while ensuring the cleaning effect.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
