Description

Technical Field

[0001] This utility model relates to the field of general cleaning or dirt removal technology using sound waves or ultrasonic vibrations, and in particular to an ultrasonic cleaning device. Background Technology

[0002] During drilling, due to the large amount of mud at the bottom of the well and the poor working conditions, mud vibrating screens are often used to vibrate and shake the mud to improve its fluidity and thus increase drilling efficiency. However, the mud at the bottom of the well has a complex composition, often containing asphalt or some fibrous materials. These substances cannot pass through the mud vibrating screen and instead stick to the screen cloth, causing blockage and reducing the working efficiency of the mud vibrating screen. At this time, the blocked screen cloth can be disassembled and cleaned to completely remove the substances adhering to it, so that the screen cloth can be reused. Currently, the disassembled screen cloth is often cleaned by a cleaning machine. However, due to the accumulation of asphalt and other fibrous materials in the mud, the cleaning machine cannot thoroughly clean and unclog the screen cloth in one go, resulting in poor cleaning effect. Usually, the screen cloth needs to be cleaned multiple times by the cleaning machine, which results in low cleaning efficiency.

[0003] To address the aforementioned issues, existing ultrasonic spray cleaning machines, due to their strong cleaning and unclogging effects, are used for cleaning screen cloths. These ultrasonic spray cleaning machines, also known as ultrasonic high-pressure spray cleaning machines, combine high-pressure spraying with ultrasonic vibration. A high-pressure spray pump delivers the cleaning fluid to the spray pipeline, allowing it to reach the high-pressure nozzles with high energy. The sprayed cleaning fluid acts on the surface of the object to be cleaned, flushing away dirt from the surface and crevices, thus achieving cleaning. This cleaning machine is suitable for rapid cleaning of large areas or complex surfaces. However, when using this ultrasonic spray cleaning machine to clean screen cloths, it cannot position or limit the screen cloths. This can cause the screen cloths to shift or stack within the machine, preventing thorough cleaning of the stacked areas. Consequently, the machine cannot clean multiple screen cloths simultaneously. When multiple screen cloths are placed inside the machine, they tend to stack and easily sink to the bottom or become entangled in the cleaning fluid, affecting the cleaning efficiency and effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic cleaning device that solves the problems of screen cloths being unable to be positioned or limited, resulting in screen cloths shifting or stacking, and multiple screen cloths easily sinking or tangling when being cleaned simultaneously.

[0005] To achieve the above objectives, the ultrasonic cleaning device of this utility model adopts the following technical solution:

[0006] An ultrasonic cleaning device includes a cleaning chamber containing at least two sets of screen cloth positioning assemblies. Each screen cloth positioning assembly includes clamping structures disposed on opposite side walls of the cleaning chamber. Each clamping structure includes clamping members arranged opposite to each other, with the clamping members relatively close to and far from corresponding side edges of the screen cloth for clamping and releasing. The clamping members have a predetermined extension length in the vertical direction to clamp the edge of the screen cloth by a predetermined length. Clamping positions for clamping the corresponding side edges of the screen cloth are formed between the clamping members of each clamping structure.

[0007] Furthermore, the clamping structure also includes a mounting plate, which is fixed to the inner wall of the washing tank. A guide rod is fixedly connected to the clamping member, which passes through the mounting plate and slides with the mounting plate. A spring is provided between the mounting plate and the clamping member to drive the clamping member to clamp the screen cloth.

[0008] Furthermore, the clamping member is fixedly connected to two or more guide rods, and each guide rod is arranged at intervals along the vertical direction of the clamping member.

[0009] Furthermore, there are two or more springs between each mounting plate and the clamping member, and each spring is arranged at vertical intervals along the clamping member.

[0010] Furthermore, the spring is a compression spring, which is mounted between the mounting plate and the corresponding clamping member.

[0011] Furthermore, the outer wall of the cleaning tank is provided with a liquid outlet that communicates with the inside of the cleaning tank. A valve is installed at the liquid outlet and a filter device is connected to it. The valve is used to control the opening and closing of the liquid outlet.

[0012] Furthermore, the filtration device includes a filtrate tank, a cover is detachably connected to the top of the filtrate tank, a handle is fixed to the outside of the cover, and a filter screen is detachably installed on the inside of the cover.

[0013] Furthermore, the filtrate tank is provided with a slot, and the cover is provided with a locking block. The cover and the filtrate tank are connected by the locking block and the slot.

[0014] Furthermore, a base is fixedly connected to the bottom of the cleaning tank, and a leveling component is installed on the lower surface of the base.

[0015] Furthermore, the leveling component includes a support leg, the outer surface of which is provided with anti-slip texture to increase friction.

[0016] Beneficial Effects: This ultrasonic cleaning device is an improved invention. By arranging a screen cloth positioning component inside the cleaning chamber, the screen cloth is positioned. Specifically, by placing clamping structures on opposite side walls of the cleaning chamber, the corresponding side edges of the screen cloth are placed within the clamping positions between the clamping members. This close proximity of the clamping members clamps effectively holds and positions the corresponding side edges of the screen cloth, ensuring it remains flat in the cleaning solution. This prevents the screen cloth from shifting or stacking during cleaning, facilitating thorough cleaning. Multiple screen cloth positioning components can be arranged to simultaneously clamp and position multiple screen cloths within the cleaning chamber, ensuring each cloth operates independently and without interference. This prevents stacking or tangling, allowing for simultaneous cleaning of multiple screen cloths and improving cleaning efficiency and effectiveness. Attached Figure Description

[0023] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0024] During drilling, due to the large amount of mud at the bottom of the well, mud vibrating screens are often used to vibrate and shake the mud to improve drilling efficiency and increase its fluidity. However, mud often contains asphalt or some fibrous materials, which can adhere to the screen cloth of the mud vibrating screen, making the screen cloth difficult to clean. Ultrasonic spray cleaning machines use a combination of high-pressure spraying and ultrasonic vibration to flush away and quickly remove the dirt adhering to the screen cloth. However, this cleaning machine cannot position and limit the screen cloth, causing it to stack or sink in the cleaning fluid, resulting in incomplete cleaning and the presence of dirt. It also cannot clean multiple screen cloths simultaneously. To address this problem, screen cloth positioning components can be installed in the cleaning machine to position the two edges of the screen cloth, thus preventing stacking or sinking in the cleaning fluid. Furthermore, by installing multiple sets of screen cloth positioning components, multiple screen cloths can be cleaned simultaneously. Based on the above inventive concept, this utility model proposes an ultrasonic cleaning device. By setting multiple sets of screen cloth positioning components inside the ultrasonic cleaning device, the two sides of the screen cloth are clamped by the screen cloth positioning components to achieve the positioning of the screen cloth. Moreover, the multiple screen cloths do not affect each other, avoiding the screen cloths from stacking or tangling, and ensuring that the screen cloths are thoroughly cleaned.

[0025] The embodiments of the ultrasonic cleaning device of this utility model are as follows:

[0026] See Figures 1 to 3 As a basic embodiment of this utility model, the ultrasonic cleaning device includes a cleaning box 1. At least two sets of screen cloth positioning assemblies are arranged inside the cleaning box 1. The screen cloth positioning assemblies enable the positioning of the screen cloth. Each screen cloth positioning assembly includes clamping structures 2 arranged on opposite side walls of the cleaning box 1. Each clamping structure 2 includes clamping members 3 arranged opposite to each other. The clamping members 3 are relatively close to and away from the corresponding side edges of the screen cloth that can be clamped and released. The clamping members 3 have a predetermined extension length in the vertical direction to clamp the edge of the screen cloth by a predetermined length. Clamping positions for clamping the corresponding side edges of the screen cloth are formed between the clamping members 3 of each clamping structure 2. When it is necessary to position the screen cloth, the corresponding side edges of the screen cloth are... The edges are placed within the clamping positions between the clamping members 3, so that the relatively arranged clamping members 3 are close to each other, thereby achieving clamping and positioning of the corresponding side edges of the screen cloth. This ensures that the screen cloth remains flat in the cleaning liquid in the cleaning tank 1, preventing the screen cloth from shifting or stacking during the cleaning process, facilitating thorough cleaning of the screen cloth. Furthermore, a certain number of screen cloth positioning components can be added according to usage requirements, allowing multiple screen cloths to be clamped and positioned simultaneously in the cleaning tank 1. At this time, the multiple screen cloths are independent of each other and do not affect each other, preventing multiple screen cloths from stacking or tangling. This achieves simultaneous cleaning of multiple screen cloths, improving cleaning efficiency and cleaning effect.

[0027] In the basic embodiment of this utility model, an ultrasonic generator 15 is installed inside the cleaning tank 1. The high-frequency mechanical oscillation generated by the ultrasonic generator 15 is used to propagate into the cleaning liquid inside the cleaning tank 1. This process will cause the cleaning liquid to form a large number of bubbles. These bubbles act on the surface and gaps of the screen cloth soaked in the cleaning liquid, which can remove the dirt from the surface and gaps of the screen cloth, thereby achieving thorough cleaning of the screen cloth.

[0028] In a preferred embodiment of this utility model, the clamping structure 2 further includes a mounting plate 4, which is fixed to the inner wall of the washing tank 1. A guide rod 5 is fixedly connected to the clamping member 3. The guide rod 5 passes through the mounting plate 4 and slides with the mounting plate 4. A spring 6 is provided between the mounting plate 4 and the clamping member 3 to drive the clamping member 3 to clamp the screen cloth. Fixing the mounting plate 4 to the inner wall of the washing tank 1 can improve the connection stability between the clamping structure 2 and the washing tank 1 and provide good support for the two clamping members 3 to move closer or further apart. When the spring 6 drives the clamping member 3 to clamp or release the screen cloth located in the clamping position, the guide rod 5 slides relative to the mounting plate 4 to adapt to the distance that the spring 6 extends and retracts to drive the clamping member 3 to move. The setting and cooperation of the guide rod 5 and the spring 6 can make the process of the two clamping members 3 moving closer or further apart more stable and prevent deviation.

[0029] In a preferred embodiment of this utility model, the clamping member 3 is fixedly connected to two or more guide rods 5, and each guide rod 5 is arranged at intervals along the vertical direction of the clamping member 3. The more guide rods 5 there are, the more stable the sliding process of the guide rods 5 relative to the mounting plate 4 is, and the more stable the process of the corresponding clamping members 3 moving closer or further away from each other is.

[0030] In a preferred embodiment of this utility model, there are two or more springs 6 between each mounting plate 4 and the clamping member 3. The springs 6 are arranged at vertical intervals along the clamping member 3. The more springs 6 there are, the greater the driving force when the clamping member 3 approaches or separates from each other, and the greater the clamping force on the screen cloth. The positioning and clamping of the corresponding side edge of the screen cloth is more stable. The multiple springs 6 and multiple guide rods 5 work together to prevent the clamping member 3 from tilting or shifting during movement, further improving the clamping stability and reliability of the screen cloth, and preventing the screen cloth from being washed away by the cleaning liquid or ultrasonic vibration during the cleaning process and detaching from the clamping member 3.

[0031] In a preferred embodiment of this utility model, the spring 6 is a compression spring, which is mounted on the mounting plate 4 between the corresponding clamping member 3. When the compression spring is in a compressed state, the two clamping members 3 are in contact with each other and are used to clamp the screen cloth in the clamping position between the two clamping members 3. When the compression spring is compressed, the compression spring itself will generate a restoring force. At this time, the two clamping members 3 are in contact with each other and block the spring from returning to its original position. Therefore, the restoring force generated by the compression spring itself will act on the clamping member 3 connected to it, making the contact between the two clamping members 3 that are in contact with each other tighter, thereby making the clamping member 3 clamp the screen cloth more stable and firmer. In other embodiments, the spring 6 can also be a tension spring. In this case, one end of the tension spring is connected to one end of the guide rod 5 passing through the mounting plate 4, and the other end is connected to the side of the mounting plate 4 away from the clamping member 3. When it is necessary to clamp the screen cloth, the two clamping members 3 are manually controlled to move away from each other. At this time, the tension spring is stretched and generates a restoring force. Since the mounting plate 4 is fixed to the inner wall of the washing box 1, the restoring force generated by the tension spring cannot act on the mounting plate 4, but can only act on the guide rod 5 and be transmitted to the clamping member 3 through the guide rod 5, so that the clamping members 3 move closer to each other under the action of the restoring force, thereby achieving the clamping of the screen cloth.

[0032] See Figure 2 , Figure 4 As a preferred embodiment of the present invention, the outer wall of the cleaning tank 1 is provided with a liquid outlet 7 that communicates with the interior of the cleaning tank 1. A valve 8 is installed at the liquid outlet 7 and a filter device 9 is connected to it. The valve 8 is used to control the opening and closing of the liquid outlet 7. By controlling the opening and closing of the liquid outlet 7 through the valve 8, the cleaning liquid is controlled to flow out from the liquid outlet 7.

[0033] In a preferred embodiment of this utility model, the filtration device 9 includes a filtrate tank 10, with a detachable cover 11 connected to the top of the filtrate tank 10. A handle 12 is fixed to the outside of the cover 11, and a filter screen 13 is detachably installed on the inside of the cover 11. When the outlet pipe 7 is opened, the cleaning liquid flows into the filtrate tank 10 along the outlet pipe 7 and is filtered by the filter screen 13. The filter screen 13 blocks solid impurities in the cleaning liquid. When the filter screen 13 is blocked by solid impurities, the cover 11 is separated from the filtrate tank 10 by pulling the handle 12 upwards. The filter screen 13 is then removed from the inside of the filtrate tank 10 along with the cover 11. At this time, the filter screen 13 is disassembled and replaced, and the cover 11 is reconnected to the filtrate tank 10. This arrangement can avoid the problem of solid impurities blocking the outlet pipe 7 when the cleaning liquid flows directly through it, and can also reuse the filtered cleaning liquid, saving energy.

[0034] In a preferred embodiment of this utility model, the filtrate tank 10 is provided with a slot, and the cover 11 is provided with a locking block 14. The cover 11 and the filtrate tank 10 are connected by the locking block 14 and the slot. This arrangement enables the cover 11 and the filtrate tank 10 to quickly connect or quickly separate, and also facilitates the quick replacement of the filter screen 13, thereby improving the cleaning efficiency of the screen cloth.

[0035] See Figure 1 In a preferred embodiment of this utility model, a control panel 16 is installed on the outer surface of the cleaning tank 1. The control panel 16 is equipped with an ultrasonic control knob 17 and an indicator light 18. The ultrasonic control knob 17 is electrically connected to the ultrasonic generator 15 and is used to control the operation of the ultrasonic generator 15. When the screen cloth needs to be cleaned, the ultrasonic control knob 17 is rotated to start the ultrasonic generator 15. At this time, the indicator light 18 is lit. When the cleaning is finished, the ultrasonic control knob 17 is rotated in the opposite direction to stop the ultrasonic generator 15 from working. At this time, the indicator light 18 is turned off.

[0036] See Figure 2 , Figure 5 In a preferred embodiment of this utility model, a base 19 is fixedly connected to the bottom of the cleaning tank 1. A leveling component 20 is installed on the base 19. The leveling component 20 can adjust the height of the base 19, thereby adjusting the height of the cleaning tank 1, so that the device can be used in environments with slopes or poor road conditions, thus improving the applicability of the device.

[0037] In this embodiment, the leveling component 20 includes a connecting plate 21 fixed to the base 19. An internally threaded sleeve 22 is fixedly installed on the connecting plate 21. An externally threaded post 23 is internally threaded to the internally threaded sleeve 22. A rotating disk 24 is fixedly connected to the externally threaded post 23. A support foot 25 is installed on the rotating disk 24. The outer surface of the support foot 25 is provided with anti-slip texture 26 to increase friction. The anti-slip texture 26 can improve friction and thus improve the stability of the entire device. When the cleaning box 1 is placed on a slope or uneven road surface, by rotating the rotating disk 24, the externally threaded post 23 can be rotated inside the internally threaded sleeve 22. The height of the externally threaded post 23 can be adjusted, thereby achieving the leveling of the cleaning box 1 and keeping the cleaning box 1 in a horizontal state.

[0038] The ultrasonic cleaning device of this utility model is used as follows: When the screen cloth needs to be cleaned, the cleaning box 1 is first leveled by the leveling component 20. By rotating the rotating disk 24, the rotating disk 24 drives the external threaded column 23 to rotate in the internal threaded sleeve 22, thereby adjusting the height of the external threaded column 23 and thus leveling the cleaning box 1. Then, the two clamping parts 3 that are in contact with each other are manually controlled to move away from each other. The screen cloth is placed in the clamping position between the two clamping parts 3. The clamping parts 3 are released, and the two clamping parts 3 will move closer to each other under the restoring force of the spring 6 and clamp the screen cloth. At this time, the screen cloth is flatly fixed in the cleaning box 1. Repeat the above operation, clamping multiple screen cloths together in the cleaning tank 1. Then rotate the ultrasonic control knob 17 to start the ultrasonic generator 15 inside the cleaning tank 1. The high-frequency mechanical vibration generated by the ultrasonic generator 15 will propagate into the cleaning fluid and cause the cleaning fluid to form a large number of bubbles. These bubbles act on the surface and gaps of the screen cloth, removing dirt from the surface and gaps of the screen cloth, thus achieving thorough cleaning of the screen cloth. After the screen cloth is cleaned, rotate the ultrasonic control knob 17 in the opposite direction to stop the ultrasonic generator 15 from working. Manually control the two clamping parts 3 to move away from each other, release the clamping of the screen cloth, and remove the cleaned screen cloth.
