Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to an ultrasonic cleaning device and method for oil pump maintenance. Background Art

[0002] Ultrasonic cleaning can greatly improve the efficiency of oil pump cleaning. The specific cleaning process is to place the oil pump that needs maintenance and cleaning in the tank, and place the oil pump in the cleaning liquid. Under the action of ultrasonic waves, the impurities remaining on the surface of the oil pump are separated from the surface of the oil pump, achieving deep cleaning of the oil pump surface.

[0003] During the cleaning process, the oil pump is statically placed in the cleaning tank. There are cleaning dead corners in the static cleaning process of the oil pump, especially when the bearing area at the bottom of the cleaning tank is large, the contact surface between the oil pump and the cleaning tank is difficult to deeply clean.

[0004] Some companies adjust the placement of the oil pump during cleaning so that the surface of the oil pump can be completely exposed to the cleaning liquid, which can improve the cleaning effect of the oil pump; however, the above operation is relatively complicated and is not suitable for batch cleaning of large quantities of oil pumps.

[0005] Some designs can automatically change the load-bearing position of the oil pump through a lifting and alternating clamping structure, which can also improve the cleaning effect of the oil pump; however, adjusting the position of the oil pump through the above structure requires a large investment in equipment modification, and each oil pump needs to be equipped with a dedicated lifting and clamping structure. The actual operation process is still cumbersome, and this maintenance and cleaning solution still has certain limitations, which affects the efficiency and adaptability of oil pump cleaning.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] During the long-term oil pumping process, a large amount of oil will remain inside the oil pump. Some of the oil contains solid impurities. During the long-term oil pumping process, some of these solid impurities remain inside the oil pump. In order to ensure the normal oil pumping effect of the oil pump, regular maintenance and cleaning of the pump air is required.

[0034] For some non-high-precision oil pump maintenance and cleaning, ultrasonic cleaning can greatly improve the efficiency of oil pump cleaning. The specific cleaning process is to place the oil pump that needs maintenance and cleaning in the tank, and place the oil pump in the cleaning liquid. Under the action of ultrasonic waves, the impurities remaining on the surface of the oil pump are separated from the surface of the oil pump, achieving deep cleaning of the oil pump surface.

[0035] During the cleaning process, the oil pump is statically placed in the cleaning tank. There are cleaning dead corners in the static cleaning process of the oil pump, especially when the bearing area at the bottom of the cleaning tank is large, the contact surface between the oil pump and the cleaning tank is difficult to deeply clean.

[0036] Some companies adjust the placement of the oil pump during cleaning so that the surface of the oil pump can be completely exposed to the cleaning liquid, which can improve the cleaning effect of the oil pump; however, the above operation is relatively complicated and is not suitable for batch cleaning of large quantities of oil pumps; some designs can automatically change the load-bearing position of the oil pump through a lifting and alternating clamping structure, which can also improve the cleaning effect of the oil pump; however, adjusting the position of the oil pump through the above structure requires a large investment in equipment modification, and each oil pump needs to be equipped with a dedicated lifting and clamping structure. The actual operation process is still cumbersome, and this maintenance and cleaning solution still has certain limitations, which affects the efficiency and adaptability of oil pump cleaning.

[0037] In order to solve the above problems, refer to the attached Figure 1 -Attached Fig.10 A novel ultrasonic cleaning device for oil pump maintenance includes a cleaning device 100. A cleaning chamber is provided inside the cleaning device 100. An ultrasonic generating device and a limiting device 300 are arranged in the cleaning chamber. The limiting device 300 includes a belt conveyor 500. A positioning device 600 is arranged on the surface of the belt conveyor 500. A carrying device 700 is detachably connected to the outer side of the positioning device 600. A carrying area 750 for accommodating an oil pump is formed between the carrying device 700 and the belt conveyor 500. During ultrasonic cleaning, the oil pump is placed in the carrying area 750, the carrying area 750 is immersed in the cleaning liquid, and the oil pump is also immersed in the oil pump to achieve deep cleaning.

[0038] The carrying device 700 here is designed to be detachable and washable, and the oil pumps are centrally placed in the carrying area 750 of the carrying device 700 to achieve accommodation. When the carrying device 700 is installed on the outside of the positioning device 600, an area for limiting the oil pump is formed between the carrying device 700 and the positioning device 600; the oil pump here can be placed as a whole in the carrying area 750 for cleaning, and the oil pump can also be disassembled and placed in the carrying area 750 for deep cleaning; the carrying area 750 here can be set to multiple, a single oil pump can be disassembled and opened and placed in the corresponding carrying area 750, and the same parts in multiple oil pumps can also be placed in the same carrying area 750 to achieve ultrasonic cleaning.

[0039] In order to solve the defects caused by static cleaning of the oil pump; a first cleaning area 310 is formed above the limiting device 300, and a second cleaning area 320 is formed below the limiting device 300; the carrying device 700 is controlled to be alternately located on the first cleaning area 310 and the second cleaning area 320 to complete the ultrasonic cleaning of the oil pump, the first cleaning area 310 and the second cleaning area 320 are respectively located on both sides of the carrying device 700, the oil pump is located in the first cleaning area 310, and under the action of gravity, its bottom is located on the side close to the belt conveyor 500, when the oil pump is located in the second cleaning area 320, under the action of gravity, its bottom is located on the side away from the belt conveyor 500; during the ultrasonic cleaning process, the bottom position of the oil pump can be adjusted by adjusting the cleaning area, which effectively solves the problem that the bottom of the oil pump is hidden and difficult to clean.

[0040] The positions of the carrier device 700 and the oil pump can be controlled by controlling the rotation of the belt conveyor device 500, so that the oil pump can be alternately located in the first cleaning area 310 and the second cleaning area 320 to achieve ultrasonic cleaning, thereby improving the ultrasonic cleaning effect on the surface of the oil pump.

[0041] In summary, through the above-mentioned structural design, by adjusting the cleaning area of ​​the oil pump and using gravity to adjust the bottom position of the oil pump, the surface of the oil pump can be completely exposed to the cleaning liquid, thereby improving the cleaning effect of the surface of the oil pump; at the same time, the above-mentioned structure only needs to adjust the position of the supporting device 700 to achieve the adjustment of the bottom position of the oil pump, and there is no need to design a separate lifting and alternating clamping device. The equipment investment cost is low, the control process is simple and efficient, and the control process can be quickly switched through the motor. No human participation is required during the ultrasonic cleaning process, which greatly improves the efficiency of ultrasonic cleaning of the oil pump.

[0042] Please refer to the attached Fig.10Specifically, the carrying device 700 includes a carrying frame body 710, and the carrying frame body 710 includes a chain plate-shaped carrying bottom wall 740 and a carrying side wall 730. A plurality of limiting columns 720 are arranged on the surface of the carrying frame body 710 at intervals. The positioning device 600 includes a first positioning assembly 610 adapted to the limiting columns 720. It should be noted that the above-mentioned chain plate-shaped structure is a grid-style structure, which can form a hollow carrying area. During the supermarket cleaning process, the contact area between the carrying device 700 and the oil pump is reduced, thereby reducing the cleaning dead angle and further improving the ultrasonic cleaning effect on the surface of the oil pump.

[0043] Multiple limiting columns 720 are located at the four corners, and the supporting device 700 is detachably connected to the positioning device 600 via the limiting columns 720. Specifically, the limiting columns 720 are detachably connected to the first positioning assembly 610, thereby realizing rapid positioning and installation of the supporting device 700 and ensuring the stability of the oil pump during ultrasonic cleaning.

[0044] Specifically, the first positioning assembly 610 includes a first positioning plate 611 connected to the belt conveyor 500, a limiting protrusion 612 is fixed on the side wall of the first positioning plate 611, a positioning groove adapted to the limiting protrusion 612 is opened on the upper end surface of the limiting column 720, and a locking assembly for locking the limiting protrusion 612 is arranged in the positioning groove. The installation direction of the first positioning plate 611 is perpendicular to the rotation direction of the belt conveyor 500. The strip design of the first positioning plate 611 meets the requirement of reversing at the edge of the belt conveyor 500 during rotation.

[0045] During the locking and positioning process, the limiting protrusion 612 on the side wall of the first positioning plate 611 can extend into the limiting column 720, and the locking component can grab the limiting protrusion 612 in a locked state to achieve the locking and limiting of the limiting protrusion 612; the locking component here can be selected as an existing telescopic structure, and a locking hole adapted to the limiting protrusion 612 is opened on the side wall, and the telescopic end of the telescopic structure enters the locking hole to achieve fast and efficient locking and positioning.

[0046] Specifically, the positioning device 600 also includes a plurality of second positioning components 620 arranged at intervals, and the plurality of second positioning components 620 are all located within the horizontal projection range of the carrier body 710. The second positioning components 620 are retractable, and the second positioning components 620 can be controlled to extend and press against the top position of the oil pump to ensure the stability of the oil pump during cleaning and switching movements. When the carrier 700 switches between the first cleaning area 310 and the second cleaning area 320, the second positioning component 620 is controlled to extend to press against the oil pump to ensure the stability of the oil pump during switching movements between the first cleaning area 310 and the second cleaning area 320. After the oil pump switches the cleaning area, the second positioning component 620 is controlled to retract to the initial position, at which time the oil pump can be synchronously lowered under the action of gravity, and the previous bottom cleaning position of the oil pump is changed to the top cleaning position. During the cleaning process, the cleaning posture can be flipped 180°, exposing the bottom of the oil pump to fully contact with the cleaning liquid, avoiding dead corners during the cleaning process of the oil pump, and improving the cleaning effect on the surface of the oil pump.

[0047] It should be noted here that the second positioning components 620 are arranged in parallel in multiple numbers. After the multiple second positioning components 620 are extended, the oil pumps or oil pump accessories at the corresponding positions can be pressed together to prevent the oil pumps from shaking during the switching and moving process, thereby ensuring the stability of the oil pumps during the cleaning process; the regional second positioning components 620 are designed to press together oil pumps or oil pump accessories of different sizes to ensure their adaptability.

[0048] It should also be noted here that during the oil pump cleaning process, the oil pump needs to be placed at a predetermined position on the surface of the supporting device 700 to avoid the second positioning component 620 in the corresponding area being located on the side of the adjacent second positioning component 620 to avoid the adjacent second positioning component 620 being unable to extend and tighten during the process.

[0049] In summary, through the above-mentioned structural design, the stability of the oil pump during the switching process can be guaranteed, the oil pump can be prevented from flipping during the switching process, and damage to the structural surfaces of the oil pump and the supporting device 700 can be prevented; at the same time, the oil pump here can achieve 180° posture switching after flipping and moving, and the bottom of the oil pump can be completely exposed to the cleaning liquid after the posture switching, thereby improving the cleaning effect of the oil pump surface.

[0050] Please refer to the attached Fig. 9Specifically, the second positioning assembly 620 includes a second positioning plate 621 and a third positioning plate 623, a hydraulic telescopic element 622 is arranged between the second positioning plate 621 and the third positioning plate 623, and an elastic sac-like structure 624 is fixed to the outer surface of the third positioning plate 623. The oil is controlled to be pumped into the hydraulic telescopic element 622, and the hydraulic telescopic element 622 can be controlled to extend so that the sac-like structure 624 can be pressed against the surface of the oil pump. The design of the sac-like structure 624 can press against the surface of the oil pump and the oil pump accessories, especially for the oil pump accessories with regular surfaces. The above-mentioned structural design can improve the pressing effect of the second positioning assembly 620 on the oil pump.

[0051] The second positioning plate 621 here is fixed to the surface of the belt conveyor 500, and its installation structure is similar to that of the first positioning plate 611. Its length extension direction is perpendicular to the moving direction of the belt conveyor 500, thereby ensuring that the second positioning plate 621 can continue to move circumferentially on the surface of the belt conveyor 500.

[0052] A sealing piston is sealingly and slidingly connected to the inner wall of the hydraulic telescopic element 622, and the sealing piston separates the hydraulic telescopic element 622 into a first control chamber away from the third positioning plate 623 and a second control chamber close to the third positioning plate 623. The second control chamber is filled with a control medium, and the second control chamber is connected to the sac-like structure 624 through a control pipe. The first control chamber is connected to an oil pump device, and the control oil is pumped into the first control chamber through the oil pump device to push the sealing piston to move, thereby realizing the overall telescopic control of the hydraulic telescopic element 622.

[0053] Furthermore, when the first control chamber is enlarged and the second control chamber is compressed, the control medium in the second control chamber can enter the sac-like structure 624 through the control pipe to control the expansion of the sac-like structure 624. The expanded sac-like structure 624 can move toward other irregular positions, thereby increasing the contact area with the surface of the oil pump or the oil pump accessories, and further improving the stability of limiting the oil pump or the oil pump accessories.

[0054] The above-mentioned control medium is preferably an electrorheological fluid. After the hydraulic telescopic element 622 is extended, the electrorheological fluid in the sac-like structure 624 is controlled to conduct electricity and become solid, which can improve the carrying capacity and effect of the sac-like structure 624, and further ensure the stability of the oil pump during the switching and moving process, especially for some large-mass oil pumps. At the same time, it can also avoid damage to the surface of the sac-like structure 624 and ensure the integrity of the overall structure.

[0055] Furthermore, a flip control device 400 is also provided on the inner wall of the cleaning device 100, through which the flip control device 400 can control the overall structure of the belt conveyor device 500 to flip, so that multiple carrying devices 700 at the bottom position can be synchronously flipped to the top position, realizing rapid switching control.

[0056] The above-mentioned structural design has multiple advantages. First, it can realize the synchronous flipping control of multiple carrying devices 700, without controlling the movement of individual carrying devices 700 one by one through the belt conveyor 500, which greatly improves the efficiency of switching and moving the carrying devices 700; at the same time, the above-mentioned structural design can reduce the movement path of the oil pump in the carrying device 700 during the flipping process, avoid the shaking of the oil pump during the transportation process, improve the stability of the oil pump and the overall structure, and avoid damage to the oil pump and the equipment; and, through the above-mentioned structural design, the length of the carrying device 700 can be designed to be larger and the thickness of the belt conveyor 500 can be lower, so that larger-sized oil pumps can be cleaned, while reducing the volume of the cleaning equipment, reducing the cleaning cost and improving the adaptability of the cleaned oil pump.

[0057] Specifically, the flip control device 400 includes a flip control frame 410 connected to the belt conveyor 500 and an electric control device 430 for driving the flip control frame 410 to rotate, wherein the flip control device 400 controls the carrying device 700 to be alternately located on one side of the first cleaning area 310 and the second cleaning area 320 to complete the ultrasonic cleaning of the oil pump, and a positioning frame 420 is fixed on the inner wall of the cleaning device 100 to carry the flip control frame 410. The flip control frame 410 includes a control frame body 411 and a flip shaft 412 fixedly connected to the control frame body 411. The flip shaft 412 is rotationally connected to the positioning frame 420. The overall flip control can be achieved by controlling the flip shaft 412 to rotate by the electric control device 430.

[0058] Furthermore, a material conveying device 200 is also provided on the inner wall of the cleaning device 100. The material conveying device 200 is located below the belt conveyor device 500 to realize loading and unloading of the carrying device 700. Loading and unloading of the carrying device 700 containing the oil pump is carried out from the bottom, which can reduce the difficulty of installing the carrying device 700. During the installation process, it is only necessary to control the carrying device 700 to move toward the top to realize the clamping limit of the carrying device 700. During this process, the oil pump is stably located on the surface of the carrying device 700 under the action of gravity, thereby ensuring the stability of its placement posture and facilitating the subsequent deep cleaning of the oil pump.

[0059] Specifically, the material conveying device 200 includes a loading conveying component 210 and a unloading conveying component 220, and the loading conveying component 210 and the unloading conveying component 220 are respectively located at two ends of the belt conveyor device 500, and the belt conveyor device 500 is electrically connected to the loading conveying component 210 and the unloading conveying component 220. During the loading and unloading process, the loading conveying component 210, the unloading conveying component 220 and the belt conveyor device 500 are controlled to rotate in coordination, so as to realize continuous loading and unloading of the carrying device 700.

[0060] The loading conveying assembly 210 here includes a loading lifting assembly 211 and a loading conveyor belt 212, and the unloading conveying assembly 220 here includes a unloading lifting assembly 221 and a unloading conveyor belt 222. During the loading and unloading process, the loading conveyor belt 212 and the unloading conveyor belt 222 are respectively controlled to move up and down, thereby respectively realizing the lifting and clamping and relay bearing of the carrying device 700; in the process of controlling the directional rotation of the belt conveyor device 500, the automatic unloading and loading of the carrying device 700 can be realized synchronously, thereby reducing the time other than the ultrasonic cleaning of the oil pump and greatly improving the efficiency of the ultrasonic cleaning of the oil pump.

[0061] The present invention is further described below in conjunction with the cleaning method.

[0062] An ultrasonic cleaning method for oil pump maintenance, using the above-mentioned ultrasonic cleaning device for oil pump maintenance, comprises the following steps:

[0063] S1. Place the oil pump that needs maintenance in the carrying device 700, and then install the carrying device 700 on the outside of the positioning device 600; the top of the oil pump in the carrying device 700 is in a state of being limited by the positioning device 600, and the oil pump is located in a relatively stable range in the enclosed state to achieve ultrasonic cleaning; the carrying devices 700 here can be arranged in parallel in multiples, and multiple carrying devices 700 containing oil pumps can be continuously loaded and positioned, thereby increasing the number of oil pumps cleaned by a single ultrasonic cleaning.

[0064] S2. Start the ultrasonic generating device and control the carrying device 700 to be located at one side of the second cleaning area 320 to complete ultrasonic cleaning of the oil pump; at this time, the first side surface of the oil pump is in contact with the carrying device 700, and under the action of ultrasonic waves, the second side surface of the oil pump can be deeply cleaned.

[0065] S3. After the oil pump is cleaned on the side of the second cleaning area 320, the carrying device 700 is controlled to move to the side of the first cleaning area 310, and the carrying device 700 is controlled to be located on the side of the first cleaning area 310 to complete the ultrasonic cleaning of the oil pump; at this time, the second side surface of the oil pump can be in contact with the surface of the positioning device 600, and under the action of ultrasonic waves, the first side surface of the oil pump can be deeply cleaned.

[0066] Through the above cleaning method, the surfaces on both sides of the oil pump can be deeply cleaned alternately, avoiding the cleaning dead corners at the bottom during the traditional cleaning process, and greatly improving the efficiency and effect of oil pump cleaning.
