Description

Technical Field

[0001] This invention relates to an electronic isopropanol container cleaning device and cleaning method. Background Technology

[0002] Electronic isopropanol, as a high-purity electronic-grade chemical, is widely used in electronics manufacturing, precision instrument cleaning, semiconductor processing, and other fields. The cleanliness of its storage container (tonne container) directly determines the purity maintenance and subsequent safety of electronic isopropanol. Therefore, the tonne containers must be rigorously cleaned before first use and during the interval between reuses. The core objective is to thoroughly remove residual impurities, oil, trace contaminants, and residues from previous storage media from the inner and outer walls of the container to avoid secondary contamination of the electronic isopropanol.

[0003] Currently, the cleaning methods for electronic isopropanol containers mainly rely on traditional cleaning technologies, including fixed high-pressure water gun rinsing, manual wiping, and static soaking cleaning. These methods have many unresolved technical drawbacks, as follows:

[0004] 1. Significant blind spots in cleaning and insufficient cleanliness: Traditional fixed high-pressure water guns often use single-direction or limited-angle rinsing, which can easily create cleaning dead spots in the corners, joints, and inner wall welds of the ton container, making it difficult for high-pressure fluid to effectively cover them; at the same time, the ton container is a large-capacity columnar structure, and the outer curved surface and deep inner wall residues are difficult to remove by a single rinsing method, resulting in trace impurities remaining after cleaning, which cannot meet the high cleanliness requirements of electronic isopropanol for storage containers;

[0005] 2. High operational intensity and poor safety: To reduce blind spots in cleaning, existing technologies often require manual assistance in turning over and moving the ton container to adjust its cleaning posture. However, electronic isopropanol ton containers are large in volume and heavy when fully loaded with cleaning fluid, making manual turning operations extremely labor-intensive and prone to accidents such as bumps and tipping. At the same time, manual contact with the surface of the ton container may introduce new contaminants, further affecting the cleaning effect.

[0006] 3. Lack of coordinated internal and external cleaning, resulting in prominent residue problems: Existing cleaning methods mostly focus on external rinsing, neglecting the targeted treatment of residues inside the container. It is difficult to penetrate the stubborn residues attached to the inner wall by using only external high-pressure fluid. At the same time, the flow path of the cleaning fluid during the cleaning process is not optimized, which easily leads to the formation of liquid residues inside the container, which are difficult to remove completely later, thus affecting the storage purity of electronic isopropanol.

[0007] In view of this, the present invention proposes an electronic isopropanol tonne cleaning device and cleaning method to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide an electronic isopropanol container cleaning device and cleaning method to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] An electronic isopropyl alcohol ton container cleaning device includes a cleaning chamber, wherein a placement ball for placing the ton container is provided inside the cleaning chamber, and the surface of the placement ball is provided with multiple sets of cleaning through holes, and the placement ball is rotatably disposed inside the cleaning chamber.

[0011] The inner wall of the cleaning chamber is provided with multiple sets of mounting plates, and high-pressure water guns are provided on the mounting plates. The outlet of the high-pressure water guns is set towards the direction of the placed ball, so that the high-pressure cleaning fluid impacts the placed ball and cleans the surface of the ton barrel through the cleaning through hole, and drives the placed ball to roll in the cleaning chamber to adjust the cleaning position.

[0012] As an improvement to the above technical solution, the cleaning tank is provided with multiple sets of support rods, each support rod is provided with a support block, and a support ball is rolled in the support block, with the support ball in contact with the surface of the ball.

[0013] As an improvement to the above technical solution, the support rod is provided with a bending rod, and the support block is provided on the bending rod, such that the opening of the support block is oriented towards the direction in which the ball is placed.

[0014] The multiple sets of support rods are arranged in a circular array, so that the multiple sets of support spheres are in contact with the surface of the placed sphere, thus supporting the placed sphere.

[0015] As an improvement to the above technical solution, a hoisting device is provided on the side of the cleaning box;

[0016] A connecting pipe is provided between the high-pressure water gun and the cleaning tank. The connecting pipe is connected to the inner cavity of the cleaning tank, and a pump body is provided on the connecting pipe to provide high-pressure cleaning fluid to the high-pressure water gun.

[0017] As an improvement to the above technical solution, the placement of the sphere includes two sets of placement arc-shaped covers, the two sets of placement arc-shaped covers have the same structure, and a connecting component is provided between the two sets of placement arc-shaped covers;

[0018] The arc-shaped cover is evenly provided with four sets of limiting plates, and the limiting plates are provided with limiting grooves that are adapted to the end corners of the ton barrel.

[0019] As an improvement to the above technical solution, the connecting component includes a first connecting ring and a second connecting ring, wherein the first connecting ring and the second connecting ring are respectively connected to two sets of arc-shaped covers.

[0020] The first connecting ring is disposed inside the second connecting ring, so that the two sets of arc-shaped covers and connecting components are connected to form a sphere.

[0021] As an improvement to the above technical solution, a plurality of first positioning holes are uniformly arranged on the side wall of the first connecting ring, and a plurality of second positioning holes are uniformly arranged on the side wall of the second connecting ring.

[0022] Multiple sets of first positioning holes and multiple sets of second positioning holes are matched in position, and positioning bolts are provided between the first positioning holes and the second positioning holes.

[0023] As an improvement to the above technical solution, the diameter of the supporting sphere is greater than the maximum spacing length of the cleaning through holes;

[0024] The interior of the arc-shaped cover has multiple cavities.

[0025] A cleaning method for an electronic isopropanol tank cleaning device includes the following steps:

[0026] Step S1: Inject a preset amount of cleaning fluid into the electronic isopropanol ton container. The preset amount satisfies the following: the total weight of the ton container, the cleaning fluid inside the container, and the sphere that will subsequently support the ton container is sufficient to enable the sphere to be stably suspended after being pressed into the cleaning tank containing half of its own volume of cleaning fluid.

[0027] Step S2: Place the pre-treated ton container into a support assembly consisting of two sets of identical placement arc covers. The ton container is precisely fitted and positioned by the limiting grooves on the four sets of limiting plates evenly distributed inside each set of placement arc covers. Then, the two sets of placement arc covers are connected and locked together by the connecting assembly to form a placement sphere with multiple sets of cleaning through holes on the surface.

[0028] Step S3: Using the hoisting device on the side of the cleaning tank, the placement ball containing the ton container is hoisted into the cleaning tank which has been pre-filled with half the volume of cleaning liquid, so that the placement ball forms rolling contact with the support balls arranged in a ring array inside the cleaning tank. The support balls are connected to the support rods inside the cleaning tank through bending rods to achieve radial limiting and suspension support for the placement ball.

[0029] Step S4: Start the pump on the connecting pipe to deliver the cleaning fluid in the cleaning tank to multiple sets of high-pressure water guns on the inner wall mounting plate of the cleaning tank through the connecting pipe. The high-pressure water guns spray high-pressure cleaning fluid in a direction tangential to the surface of the placed ball.

[0030] Step S5: The high-pressure cleaning fluid penetrates multiple sets of cleaning holes on the surface of the placed ball, forming a multi-angle dispersed impact cleaning on the inner and outer surfaces of the ton container. At the same time, the driving force generated by the tangential impact drives the placed ball to roll in the cleaning box, dynamically adjusting the cleaning posture of the ton container to achieve all-round cleaning without dead angles.

[0031] Step S6: After cleaning is completed, turn off the pump body, lift the placement ball out of the cleaning tank using the hoisting device, disassemble the connecting components to separate the two sets of placement arc covers, and take out the cleaned ton container.

[0032] As an improvement to the above technical solution, in step S4, multiple sets of high-pressure water guns are selectively activated according to the preset cleaning path, and the rolling direction and speed of the placed ball are precisely controlled by adjusting the number and position of the activated sets.

[0033] In step S2, the connecting component forms a double positioning by nesting the first connecting ring inside the second connecting ring, and then locks it by passing the positioning bolt through the first positioning hole and the second positioning hole that match the position.

[0034] In step S5, multiple sets of cleaning through holes are evenly distributed along the surface of the placed sphere, so that the high-pressure cleaning fluid forms a divergent impact pattern, which, together with the rolling of the placed sphere, achieves dynamic superimposed coverage cleaning.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] Through the coordinated design of multiple sets of high-pressure water guns and the placement ball, the water outlet direction of the high-pressure water guns is tangential to the surface of the placement ball. While the high-pressure cleaning fluid penetrates the cleaning through hole to impact and clean the surface of the ton container, it can drive the placement ball to roll in the cleaning tank. Moreover, multiple sets of high-pressure water guns can be selectively turned on as needed to control the rolling direction of the placement ball, so that the ton container can continuously adjust its cleaning posture during the rolling process, completely avoiding the cleaning blind spots that exist in traditional cleaning methods, and ensuring that all areas of the ton container surface can be thoroughly cleaned.

[0037] The high-pressure cleaning fluid has the dual functions of direct impact cleaning and driving the rolling of the placement ball. It eliminates the need for an additional power mechanism to drive the movement of the placement ball, simplifying the structure while enabling simultaneous cleaning action and posture adjustment, significantly shortening the cleaning cycle. At the same time, the cleaning fluid pre-injected inside the ton and the external high-pressure cleaning fluid create a synergistic cleaning effect, effectively removing impurities from the surface and inside of the ton for the special cleanliness requirements of electronic isopropanol tons, improving the cleanliness to meet subsequent usage needs.

[0038] The entire cleaning process only requires basic operations such as pre-filling the ton container with cleaning fluid, placing the placement ball, injecting cleaning fluid into the cleaning tank, and controlling the start and stop of the high-pressure water gun. This enables automated cleaning and posture adjustment of the ton container without the need for manual flipping or moving of the ton container, reducing labor intensity and human error, and improving operational convenience and cleaning process safety.

[0039] Through the directional impact of high-pressure cleaning fluid and the internal and external synergistic cleaning mechanism, impurities can be removed efficiently while reducing cleaning fluid residue. The overall structural design avoids the risk of introducing additional contaminants during the cleaning process, meeting the requirements of the electronic isopropanol storage tank for no residue and high cleanliness after cleaning, and ensuring the subsequent storage quality of electronic isopropanol.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example:

[0053] like Figure 1-10 As shown, this embodiment proposes an electronic isopropanol ton container cleaning device, including a cleaning box 30. The cleaning box 30 is provided with a placement ball 20 for placing the ton container. The surface of the placement ball 20 is provided with multiple sets of cleaning through holes 24. The placement ball 20 is rolled inside the cleaning box 30.

[0054] The inner wall of the cleaning chamber 30 is provided with multiple sets of mounting plates 31. A high-pressure water gun 40 is provided on the mounting plate 31. The outlet of the high-pressure water gun 40 is set towards the placement ball 20, so that the high-pressure cleaning fluid impacts the placement ball 20 to clean the surface of the ton barrel through the cleaning through hole 24, and drives the placement ball 20 to roll and adjust the cleaning position in the cleaning chamber 30.

[0055] In this embodiment, when cleaning the ton container, an appropriate amount of cleaning fluid is first injected into the ton container. Then, the ton container is placed in the placement ball 20. Next, half the capacity of the cleaning tank 30 is injected into the cleaning tank 30, so that the placement ball 20 can roll in the cleaning tank 30. Then, the high-pressure water gun 40 starts to operate, so that the high-pressure cleaning fluid impacts the surface of the placement ball 20 and cleans the surface of the ton container through the cleaning through hole 24. When the high-pressure cleaning fluid impacts the surface of the placement ball 20, it can drive the placement ball 20 to roll in the cleaning tank 30, thereby adjusting the cleaning position of the ton container.

[0056] Of course, when an appropriate amount of cleaning fluid is injected into the ton, the total amount of the ton, the cleaning fluid inside the ton, and the placed ball 20 can press the placed ball 20 into the cleaning tank 30 which has half the capacity of cleaning fluid, so that the placed ball 20 can be suspended in the cleaning tank 30.

[0057] Of course, the water outlet direction of the high-pressure water gun 40 is tangent to the surface of the ball 20, so that the ball 20 can be rolled by the impact of the water outlet of the high-pressure water gun 40.

[0058] Of course, the multiple sets of high-pressure water guns 40 can be adjusted to be turned on or off according to the actual situation, so as to control the direction of the rolling of the ball 20 and achieve all-round cleaning of the ton container.

[0059] Through the coordinated design of multiple sets of high-pressure water guns 40 and the placement ball 20, the water outlet direction of the high-pressure water guns 40 is tangent to the surface of the placement ball 20. While the high-pressure cleaning fluid penetrates the cleaning through hole 24 to impact and clean the surface of the ton container, it can drive the placement ball 20 to roll inside the cleaning tank 30. Moreover, the multiple sets of high-pressure water guns 40 can be selectively opened as needed to control the rolling direction of the placement ball 20, so that the ton container continuously adjusts its cleaning posture during the rolling process, completely avoiding the cleaning blind spots existing in traditional cleaning methods, and ensuring that all areas of the ton container surface can be thoroughly cleaned.

[0060] The high-pressure cleaning fluid has the dual functions of direct impact cleaning and driving the placement ball 20 to roll. It eliminates the need for an additional power mechanism to drive the movement of the placement ball 20, simplifying the structure while achieving simultaneous cleaning action and posture adjustment, and significantly shortening the cleaning cycle. At the same time, the cleaning fluid pre-injected inside the ton and the external high-pressure cleaning fluid form a synergistic cleaning effect, effectively removing impurities remaining on the surface and inside the ton for the special cleanliness requirements of electronic isopropanol ton, improving the cleaning cleanliness to meet subsequent use requirements.

[0061] The entire cleaning process only requires basic operations such as pre-filling the ton container with cleaning fluid, placing the placement ball 20, injecting cleaning fluid into the cleaning tank 30, and controlling the start and stop of the high-pressure water gun 40. This enables automated cleaning and posture adjustment of the ton container without the need for manual flipping or moving of the ton container, reducing labor intensity and human error, and improving operational convenience and cleaning process safety.

[0062] Through the directional impact of high-pressure cleaning fluid and the internal and external synergistic cleaning mechanism, impurities can be removed efficiently while reducing cleaning fluid residue. The overall structural design avoids the risk of introducing additional contaminants during the cleaning process, meeting the requirements of the electronic isopropanol storage tank for no residue and high cleanliness after cleaning, and ensuring the subsequent storage quality of electronic isopropanol.

[0063] Specifically, the cleaning box 30 is provided with multiple sets of support rods 70, and support blocks 72 are provided on the support rods 70. Support balls 73 are rolled in the support blocks 72, and the support balls 73 are in contact with the surface of the placement ball 20.

[0064] In this embodiment, multiple sets of support rods 70, together with support blocks 72 and support balls 73, form a multi-point contact support structure for the ball 20, which effectively limits the radial displacement and disorderly shaking of the ball 20 in the cleaning tank 30, ensuring that the ball 20 and the ton container carried inside are always within the preset cleaning area, avoiding collision damage between the ton container and the cleaning tank 30 or other components due to the displacement of the ball 20 during the cleaning process, and improving the structural stability of the cleaning process;

[0065] The support structure achieves stable support while not hindering the rolling freedom of the placed ball 20 through the flexible rolling contact between the support ball 73 and the placed ball 20. This allows the placed ball 20 to maintain a stable posture under the constraint of the support structure and to flexibly adjust its position in response to the impact force of the high-pressure water gun 40, thus achieving a synergistic effect of stable support and smooth rolling, ensuring the continuity and reliability of the cleaning process.

[0066] Of course, when an appropriate amount of cleaning fluid is injected into the ton container, the total amount of the ton container, the cleaning fluid inside the ton container, and the placement ball 20 can press the placement ball 20 into the cleaning tank 30 with half the capacity of cleaning fluid, so that the placement ball 20 can be suspended in the cleaning tank 30. When the placement ball 20 is pressed into the cleaning tank 30 with half the capacity of cleaning fluid, the placement ball 20 contacts the multiple sets of supporting balls 73.

[0067] Specifically, the support rod 70 is provided with a bending rod 71, and the support block 72 is provided on the bending rod 71, such that the opening of the support block 72 is oriented towards the direction of placing the ball 20;

[0068] The multiple sets of support rods 70 are arranged in a ring array, so that the multiple sets of support spheres 73 are in contact with the surface of the placed sphere 20, thus supporting the placed sphere 20.

[0069] In this embodiment, by setting a bending rod 71 on the support rod 70, the installation angle and position of the support block 72 can be adjusted as needed, so that the opening of the support block 72 is precisely facing the direction of the ball 20, ensuring that the support ball 73 inside the support block 72 can form a tight and stable contact with the surface of the ball 20, avoiding ineffective support such as misalignment or separation between the support ball 73 and the ball 20, ensuring the effective support of the support structure for the ball 20, and laying a structural foundation for the stable rolling of the ball 20;

[0070] Multiple sets of support rods 70 are arranged in a ring array, driving each set of support blocks 72 and support balls 73 to be evenly arranged along the circumference of the placed ball 20. This allows multiple sets of support balls 73 to simultaneously contact the surface of the placed ball 20, forming a ring support structure with all-round and no dead angles. This structure can apply uniform radial limiting constraints to the placed ball 20, effectively suppressing radial displacement, tilting or disorderly shaking of the placed ball 20 during the cleaning process due to factors such as the impact of the high-pressure water gun 40 and its own rolling. This ensures that the placed ball 20 is always within the preset cleaning area of ​​the cleaning tank 30, avoiding collision damage between the ton container it carries and the cleaning tank 30, high-pressure water gun 40 and other components, thus ensuring the safety and stability of the cleaning process.

[0071] Specifically, a hoisting device 10 is provided on the side of the cleaning box 30;

[0072] A connecting pipe 50 is provided between the high-pressure water gun 40 and the cleaning tank 30. The connecting pipe 50 is connected to the inner cavity of the cleaning tank 30, and a pump body is provided on the connecting pipe 50 to provide high-pressure cleaning fluid to the high-pressure water gun 40.

[0073] In this embodiment, the hoisting device 10 works in conjunction with the placement sphere 20. After the ton container is fixed to the placement sphere 20, the assembled placement sphere 20 can be hoisted into the cleaning box 30 by the hoisting device 10, or hoisted out after cleaning. This simplifies the operation process of fixing the ton container, putting it into the box, and taking it out of the box, avoids secondary handling in the intermediate links, and ensures the continuity and efficiency of the cleaning process.

[0074] The connecting pipe 50 connects the inner cavity of the cleaning tank 30 to the high-pressure water gun 40. With the high-pressure output function of the pump, the cleaning fluid in the cleaning tank 30 can be stably converted into high-pressure cleaning fluid. This not only meets the cleaning requirements of penetrating the cleaning through hole 24 of the ball 20 and impacting the surface of the ton container, but also provides sufficient impact force to drive the ball 20 to roll, achieving power coordination between cleaning and attitude adjustment. There is no need to set up an additional cleaning fluid delivery mechanism or ball drive mechanism, simplifying the overall structure of the device.

[0075] Specifically, the placement sphere 20 includes two sets of placement arc-shaped covers 21, the two sets of placement arc-shaped covers 21 have the same structure, and a connecting component 60 is provided between the two sets of placement arc-shaped covers 21;

[0076] Four sets of limiting plates 22 are evenly arranged in the arc-shaped cover 21, and the limiting plates 22 are provided with limiting grooves 23 that are adapted to the end corners of the ton barrel.

[0077] In this embodiment, the placement sphere 20 is formed by two sets of identical placement arc-shaped covers 21 connected to the connecting component 60, constituting a modular disassembly design. The two sets of placement arc-shaped covers 21 can be quickly separated by disassembling the connecting component 60, facilitating the insertion and removal of the ton container. Considering the large capacity and heavy weight of the electronic isopropanol ton container, this design avoids the difficulties in loading and unloading the ton container caused by the traditional integrated bearing structure, greatly improving operational convenience and reducing the labor intensity of clamping and retrieval. At the same time, the identical structure of the two sets of placement arc-shaped covers 21 can reduce the cost of component processing and interchangeability maintenance.

[0078] Four sets of limiting plates 22 are evenly arranged inside the arc-shaped cover 21, and the limiting plates 22 are provided with limiting grooves 23 that are adapted to the end corners of the ton barrel. Through the precise engagement of the limiting grooves 23 with the end corners of the ton barrel, a multi-point positioning constraint is formed on the ton barrel. This design can effectively suppress the translation, rotation or tilting of the ton barrel in the placement ball 20 during the cleaning process, ensuring that the ton barrel always maintains the preset posture, and ensuring that the high-pressure cleaning fluid can accurately impact the surface of the ton barrel through the cleaning through hole 24, avoiding cleaning blind spots or uneven cleaning effect caused by the displacement of the ton barrel, and improving the cleaning accuracy.

[0079] Four sets of limiting plates 22 are evenly distributed, and combined with the matching contact between the limiting groove 23 and the end corner of the ton container, the force on the ton container is evenly distributed along the end corner, avoiding deformation or damage to the end corner of the ton container caused by local stress concentration. At the same time, the matching design of the limiting groove 23 can increase the contact area with the ton container and reduce the pressure per unit area. It is especially suitable for the special requirements of electronic isopropanol ton containers for structural integrity and cleanliness, avoiding the introduction of impurities or damage to the ton container due to improper clamping force, and ensuring the safety of the ton container in subsequent use.

[0080] Specifically, the connecting component 60 includes a first connecting ring 61 and a second connecting ring 63, which are respectively connected to two sets of arc-shaped covers 21.

[0081] The first connecting ring 61 is disposed inside the second connecting ring 63, so that the two sets of arc-shaped covers 21 and connecting components 60 are connected to form a sphere 20.

[0082] In this embodiment, the design of the first connecting ring 61 nested inside the second connecting ring 63 forms a dual positioning constraint in the radial and circumferential directions. This allows for rapid calibration of the docking reference of the two sets of arc-shaped covers 21, avoiding problems such as circumferential misalignment and radial offset during docking. It ensures that the two sets of arc-shaped covers 21 are precisely spliced ​​together by the connecting component 60 to form a complete and regular placement sphere 20, guaranteeing the consistency of the spherical structure of the placement sphere 20 and providing core structural support for its smooth and unobstructed rolling within the cleaning chamber 30.

[0083] Specifically, a plurality of first positioning holes 62 are evenly provided on the side wall of the first connecting ring 61, and a plurality of second positioning holes 64 are evenly provided on the side wall of the second connecting ring 63.

[0084] Multiple sets of first positioning holes 62 and multiple sets of second positioning holes 64 are matched in position, and positioning bolts are provided between the first positioning holes 62 and the second positioning holes 64.

[0085] In this embodiment, the positions of the multiple sets of first positioning holes 62 and multiple sets of second positioning holes 64 are matched, which can quickly calibrate the docking reference of the two sets of placement arc-shaped covers 21, avoid circumferential misalignment or radial offset, and ensure that the two sets of placement arc-shaped covers 21 are accurately spliced ​​to form a regular placement sphere 20; with the locking action of the positioning bolts, the first connecting ring 61 and the second connecting ring 63 are firmly fixed to form a rigid integrated connection structure, which can effectively resist the impact of high-pressure fluid during the cleaning process and the alternating load generated by the rolling of the placement sphere 20, prevent the connection parts from loosening or separating, ensure the stable bearing of the placement sphere 20 on the ton, and improve the impact resistance and reliability of the overall structure of the device.

[0086] Specifically, the diameter of the supporting sphere 73 is greater than the maximum spacing length of the cleaning through holes 24;

[0087] The interior of the arc-shaped cover 21 has multiple cavities.

[0088] In this embodiment, by limiting the dimensional relationship between the diameter of the support ball 73 and the maximum distance between the cleaning through holes 24, it is possible to effectively prevent the support ball 73 from getting embedded in the cleaning through holes 24 during the rolling process of contacting the placement ball 20. This avoids structural interference problems such as the support ball 73 getting stuck and the placement ball 20 being obstructed from rolling, and ensures that the placement ball 20 can flexibly adjust its posture in response to the impact force of the high-pressure water gun 40, providing a continuous and smooth motion basis for the all-round cleaning of the ton container.

[0089] The supporting ball 73 always forms a complete rolling contact with the surface of the placed ball 20, avoiding ineffective support such as support point offset and insufficient support force caused by embedding through holes. This ensures that multiple sets of supporting balls 73 provide uniform support to the placed ball 20 at multiple points, suppresses radial offset or tilting of the placed ball 20, and ensures that the ton container is always in the preset cleaning area during the cleaning process, thereby improving the stability and reliability of the cleaning process.

[0090] Multiple sets of cleaning through holes 24 are evenly distributed on the surface of the placement ball 20. After the high-pressure cleaning fluid sprayed by the high-pressure water gun 40 impacts the surface of the placement ball 20, it is diverted and dispersed through the multiple sets of cleaning through holes 24, which transforms the originally concentrated single-point high-pressure fluid into a multi-point, dispersed jet stream. This design breaks the traditional directional concentrated impact mode of a single high-pressure water gun 40, allowing the cleaning fluid to cover multiple areas of the ton barrel surface at the same time, significantly widening the effective coverage area of ​​a single cleaning, reducing cleaning dead corners, and providing a structural basis for all-round cleaning of the ton barrel.

[0091] The distribution angle of the multiple sets of cleaning through holes 24 is adapted to the spherical structure of the placed spheres 20, so that the dispersed cleaning fluid forms a multi-angle and multi-directional impact. The fluid ejected from the through holes at different positions can impact the surface of the ton container from different angles such as the side and the oblique direction, avoiding the problem of uneven cleaning caused by impact in a single direction. In particular, in conjunction with the rolling of the placed spheres 20, the dispersed fluid and the rolling of the spheres form a dynamic superposition and covering effect, ensuring that all areas of the ton container surface can be subjected to uniform fluid impact, effectively removing residual impurities, improving cleaning cleanliness, and meeting the special requirements of high cleanliness for electronic isopropanol ton containers.

[0092] By creating multiple cavities inside the arc-shaped cover 21, the overall density of the placed sphere 20 can be significantly reduced while ensuring the structural strength and load-bearing capacity of the arc-shaped cover 21. This significantly improves the buoyancy of the placed sphere 20 in the cleaning fluid. On the one hand, the increased buoyancy makes it easier for the total weight of the ton container, the cleaning fluid inside the container, and the placed sphere 20 to meet the preset requirement of being pushed into the cleaning tank 30 containing half its volume of cleaning fluid and achieving suspension, without the need to increase the amount of cleaning fluid injected or adjust the dosage of the pre-filled cleaning fluid in the ton container, simplifying the preparation operations before cleaning. On the other hand, sufficient buoyancy ensures that the placed sphere 20 is in a stable position in the cleaning fluid. Maintaining a stable suspended posture in the washing solution avoids frictional resistance caused by direct contact between the bottom of the placed ball 20 and the cleaning tank 30 due to insufficient buoyancy, or fluctuations in suspension height affecting the impact driving effect of the high-pressure water gun 40. This ensures that the placed ball 20 can roll smoothly under the action of the high-pressure water gun 40, thereby ensuring the continuity and uniformity of the ton tank's all-round cleaning. At the same time, the suspension stability brought about by the increased buoyancy can further disperse the contact pressure between the placed ball 20 and the supporting ball 73, reduce component wear, extend the service life of the device, and eliminate the need for additional buoyancy auxiliary structures, simplifying the overall design of the device and improving operational economy.

[0093] A cleaning device for an electronic isopropanol tank cleaning system includes the following steps:

[0094] Step S1: Inject a preset amount of cleaning fluid into the electronic isopropanol ton container. The preset amount satisfies the following: the total weight of the ton container, the cleaning fluid inside the container, and the placement ball 20 that subsequently supports the ton container is sufficient to enable the placement ball 20 to be stably suspended after being pressed into the cleaning tank 30 containing half of its own volume of cleaning fluid.

[0095] Step S2: Place the pre-treated ton container into the bearing assembly consisting of two sets of identical placement arc-shaped covers 21. The ton container is precisely fitted and positioned by the limiting grooves 23 on the four sets of limiting plates 22 evenly distributed in each set of placement arc-shaped covers 21. Then, the two sets of placement arc-shaped covers 21 are connected and locked together by the connecting assembly 60 to form a placement sphere 20 with multiple sets of cleaning through holes 24 on the surface.

[0096] Step S3: Using the hoisting device 10 on the side of the cleaning tank 30, the placement ball 20 containing the ton container is hoisted into the cleaning tank 30, which has been pre-filled with half the volume of cleaning liquid, so that the placement ball 20 and the support balls 73 arranged in a ring array inside the cleaning tank 30 form rolling contact. The support balls 73 are connected to the support rods 70 inside the cleaning tank 30 through the bending rods 71, so as to achieve radial limiting and suspension support for the placement ball 20.

[0097] Step S4: Start the pump on the connecting pipe 50 so that the cleaning liquid in the cleaning tank 30 is transported through the connecting pipe 50 to multiple sets of high-pressure water guns 40 on the mounting plate 31 on the inner wall of the cleaning tank 30. The high-pressure water guns 40 spray high-pressure cleaning fluid in a direction tangential to the surface of the placed ball 20.

[0098] Step S5: The high-pressure cleaning fluid penetrates the multiple sets of cleaning through holes 24 on the surface of the placed ball 20, forming a multi-angle dispersed impact cleaning on the inner and outer surfaces of the ton barrel. At the same time, the driving force generated by the tangential impact drives the placed ball 20 to roll in the cleaning box 30, dynamically adjusting the cleaning posture of the ton barrel to achieve all-round cleaning without dead angles.

[0099] Step S6: After cleaning is completed, turn off the pump body, lift the placement ball 20 out of the cleaning tank 30 using the hoisting device 10, disassemble the connecting assembly 60 to separate the two sets of placement arc covers 21, and take out the cleaned ton container.

[0100] Specifically, in step S4, multiple sets of high-pressure water guns 40 are selectively activated according to the preset cleaning path, and the rolling direction and speed of the placed ball 20 are precisely controlled by adjusting the number and position of the activated sets.

[0101] In step S2, the connecting component 60 forms a double positioning by nesting the first connecting ring 61 inside the second connecting ring 63, and then locks it by passing the positioning bolt through the first positioning hole 62 and the second positioning hole 64 that match the position.

[0102] In step S5, multiple sets of cleaning through holes 24 are evenly distributed along the surface of the placed ball 20, so that the high-pressure cleaning fluid forms a divergent impact pattern, and achieves dynamic superimposed coverage cleaning in conjunction with the rolling of the placed ball 20.

[0103] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
