Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning machine technology, specifically to an ultrasonic cleaning machine for cleaning compressor crankshafts. Background Technology

[0002] A compressor is a machine that raises low-pressure gas to high-pressure gas. It is the power source of the refrigeration cycle system and is often referred to as the "heart" of a refrigeration device. In a refrigeration system, the compressor compresses the low-temperature, low-pressure refrigerant vapor drawn into the evaporator into high-temperature, high-pressure refrigerant vapor and sends it to the condenser. A pressure difference is established in the system's pipes, forcing the refrigerant to circulate and achieve the purpose of refrigeration. The working principle of the compressor crankshaft is to convert the rotational motion input from the prime mover into the reciprocating motion of the piston, thereby realizing the gas compression process.

[0003] During compressor operation, various impurities, such as dust, metal shavings, and oil, will adhere to the surface of the crankshaft. Therefore, after prolonged use, an ultrasonic cleaner is used to clean the surface of the compressor crankshaft to prevent the various impurities on its surface from affecting the use of the compressor crankshaft.

[0004] Currently, the process of cleaning compressor crankshafts typically involves placing the compressor crankshaft on a rack inside the device, adding cleaning fluid to the device, and then starting the device to use ultrasonic waves installed inside to propagate the ultrasonic waves in the cleaning fluid to remove dirt from the surface of the compressor crankshaft.

[0005] However, during the cleaning process of the compressor crankshaft, since it cannot move after being placed in the rack, the cleaning effect is poor in the gaps and corners, and dirt is easily left behind. Furthermore, there is no drying measure after cleaning, and it can only be dried by natural ventilation, which makes the surface moisture not evaporate completely, affecting the quality of the crankshaft after cleaning. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide an ultrasonic cleaner for cleaning compressor crankshafts, in order to solve the technical problems that, because the crankshaft cannot move after being placed in the rack, the cleaning effect is poor in the gaps and corners, dirt is easily left behind, and there is no drying measure after cleaning, so it can only be dried by natural ventilation, which makes the surface moisture evaporate incompletely and affects the quality of the crankshaft after cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaner for cleaning compressor crankshafts, comprising a first housing, a bracket fixedly connected to the surface of the first housing, a second housing rotatably connected to the top of the first housing, an ultrasonic cleaner body fitted to the first housing mounted on the surface of the bracket, and the ultrasonic cleaner body connected to the first housing, a filter frame rotatably connected inside the first housing via a rotating shaft, a sliding groove fitted to the rotating shaft being provided inside the first housing, and the rotating shaft moving within the sliding groove, and a silencer box slidably connected inside the first housing, the silencer box containing... A first motor is installed that matches the rotating shaft, and the output end of the first motor is connected to one end of the rotating shaft. A cross shaft is movably passed through the bottom of the first housing, and a cross groove matching the cross shaft is provided at the bottom of the filter frame. A movable plate is movably connected to the bottom of the first housing. A second motor matching the cross shaft is installed on the top of the movable plate, and the output end of the second motor is connected to the cross shaft. The movable plate and the bracket are connected by a telescopic rod. A ventilation fan is installed on the top of the second housing, and a connecting block is fixedly installed at the bottom of the ventilation fan. Several heating wires are provided inside the connecting block.

[0008] By adopting the above technical solution, the second housing is rotated to offset the first housing. Then, the compressor crankshaft is placed into the filter frame and the second housing is rotated again so that the first housing and the second housing overlap. Then, the telescopic rod drives the movable plate, the second motor, and the cross shaft to move until the cross shaft is inserted into the cross groove. Thus, the second motor drives the filter frame to rotate, and the rotating shaft rotates in the sliding groove, thereby changing the position of the crankshaft in the first housing. This helps the ultrasonic waves to act more evenly on the surface of the compressor crankshaft, improving the cleaning effect and ensuring that all parts of the compressor crankshaft are thoroughly cleaned. After cleaning, the ultrasonic cleaning agent body can be turned off, and then the telescopic rod drives the cross shaft to retract into the first housing. Then, the second motor is started to drive the filter frame to rotate, allowing the liquid remaining on the surface of the compressor crankshaft to fall off. At the same time, the ventilation fan is started to allow outside air to enter the second housing and the interior of the first housing. The heating wire can heat the incoming air, thus accelerating the evaporation of moisture on the surface of the crankshaft after cleaning, drying the crankshaft, preventing rust, and improving the quality of the cleaned crankshaft.

[0009] The present invention is further configured such that a slot is provided on one side of the slide groove to fit the muffler box, and the muffler box moves within the slot.

[0010] By adopting the above technical solution, when the second motor drives the filter frame to rotate in the first housing through the cross shaft and cross groove, it also drives the silencer box to rotate in the slot, thus avoiding affecting the movement of the filter frame.

[0011] The present invention is further configured such that a limiting groove is provided at the top of the card slot, a limiting block that matches the limiting groove is slidably connected in the limiting groove, and the limiting block is fixedly connected to the top of the silencer box.

[0012] By adopting the above technical solution, the cooperation of the limiting groove and the limiting block enables the muffler box to move within a predetermined trajectory, thereby ensuring the stability of the muffler box during movement.

[0013] The present invention is further provided that a plurality of holes are provided on one side of the card slot.

[0014] By adopting the above technical solution, the design of the hole can drain the cleaning fluid in the slot, preventing it from accumulating in the slot and being difficult to drain.

[0015] The present invention is further configured such that the surface of the first housing is provided with a discharge port, and the surface of the second housing is provided with a feed port.

[0016] By adopting the above technical solution, the cleaning fluid can enter the first housing from the inlet, which facilitates the cleaning of the compressor crankshaft, and the wastewater after cleaning can be discharged through the outlet.

[0017] The present invention is further configured such that a filter cover plate is connected to the surface of the filter frame via a hinge, and the filter cover plate and the filter frame are connected by a latch.

[0018] By adopting the above technical solution, opening the filter cover facilitates the insertion of the compressor crankshaft into the filter frame for cleaning or the removal of the cleaned compressor crankshaft from the filter frame. At the same time, closing the filter cover can prevent the filter frame from falling off during the cleaning process due to the rotation of the compressor crankshaft, thus affecting the cleaning of the compressor crankshaft.

[0019] The present invention is further provided that the surfaces of the filter frame and the filter cover are both provided with a rubber layer.

[0020] By adopting the above technical solution, the rubber layer can protect the compressor crankshaft and prevent it from being damaged by collision with the frame.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention involves rotating the second housing to offset it from the first housing, then placing the compressor crankshaft into the filter frame. A telescopic rod drives the movable plate, the second motor, and the cross shaft to move until the cross shaft inserts into the cross groove. The second motor then drives the filter frame to rotate, causing the crankshaft to change position within the first housing. This facilitates more even ultrasonic cleaning of the compressor crankshaft surface, improving the cleaning effect and ensuring thorough cleaning of all parts of the crankshaft. After cleaning, the telescopic rod retracts the cross shaft into the first housing, and the second motor rotates the filter frame, allowing any remaining liquid on the compressor crankshaft surface to fall off. Simultaneously, a ventilation fan is activated, allowing outside air to enter the second and first housings. A heating wire heats the incoming air, accelerating the evaporation of moisture from the crankshaft surface after cleaning, effectively drying the crankshaft, preventing rust, and improving the quality of the cleaned crankshaft.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] An ultrasonic cleaner for cleaning compressor crankshafts, such as Figure 1-5 As shown, the device includes a first housing 1, with a bracket 2 fixedly connected to the surface of the first housing 1 to increase the stability of the first housing 1. A second housing 3 is rotatably connected to the top of the first housing 1. Rotating the second housing 3 causes the first housing 1 to open when it is misaligned with the first housing 1, and closes when it overlaps with the first housing 1. A sealing layer is used between the first housing 1 and the second housing 3 to prevent liquid leakage from their connection. An ultrasonic cleaner body 4 that fits the first housing 1 is mounted on the surface of the bracket 2 and is connected to the first housing 1. A discharge port 20 is provided on the surface of the first housing 1, and a feed port 19 is provided on the surface of the second housing 3, allowing the cleaning liquid to enter the first housing 1 and the second housing 3 through the feed port 19 and then be discharged through the discharge port 20.

[0032] Subsequently, a filter frame 7 is rotatably connected within the first housing 1 via a rotating shaft 6. The first housing 1 has a sliding groove 5 that engages with the rotating shaft 6, and the rotating shaft 6 moves within the sliding groove 5. When the filter frame 7 rotates within the first housing 1, the rotating shaft 6 moves within the sliding groove 5. A silencer box 9 is slidably connected within the first housing 1, and a first motor 8, engaging with the rotating shaft 6, is installed within the silencer box 9. The silencer box 9 protects the first motor 8, and the output end of the first motor 8 is connected to one end of the rotating shaft 6, allowing the first motor 8 to drive the filter frame 7. The filter frame 7 rotates vertically. A cross shaft 24 extends through the bottom of the first housing 1, and a cross groove 25, matching the cross shaft 24, is provided at the bottom of the filter frame 7. A movable plate 17 is movably connected to the bottom of the first housing 1. A second motor 16, matching the cross shaft 24, is mounted on the top of the movable plate 17, and its output is connected to the cross shaft 24. The movable plate 17 and the support 2 are connected by a telescopic rod 18. Therefore, when the filter frame 7 needs to rotate horizontally during cleaning, the telescopic rod 18 can be activated to drive the movable plate 17. The second motor 16 and the cross shaft 24 move upwards until the cross shaft 24 is inserted into the cross groove 25. Then, the second motor 16 can be started to rotate the filter frame 7, thereby causing the compressor crankshaft to move in the cleaning fluid. This helps the ultrasonic waves to act more evenly on the surface of the compressor crankshaft, improving the cleaning effect and ensuring that all parts of the compressor crankshaft are thoroughly cleaned. After cleaning, the cleaning fluid inside the first housing 1 is drained. Then, the first motor 8 is started to rotate the shaft 6 and the filter frame 7, allowing the cleaning fluid remaining on the surface of the compressor crankshaft to fall off, facilitating subsequent cleaning. The compressor crankshaft is dried by installing an exhaust fan 21 on the top of the second housing 3. A connecting block 22 is fixedly installed at the bottom of the exhaust fan 21, and several heating wires 23 are installed inside the connecting block 22. Therefore, after the compressor crankshaft is cleaned, the exhaust fan 21 can be started and the heating wires 23 can be turned on to allow outside air to enter the first housing 1 and the second housing 3. The air entering is heated by the heating wires 23, which can accelerate the evaporation of moisture on the surface of the compressor crankshaft, thereby drying the compressor crankshaft, preventing the compressor crankshaft from rusting, and improving the quality of the cleaned compressor crankshaft.

[0033] Furthermore, a slot 10 is provided on one side of the slide groove 5 to fit the silencer box 9, and the silencer box 9 moves within the slot 10. The design of the slot 10 provides space for the silencer box 9 to move, thereby better driving the filter frame 7 to rotate. Several holes 13 are provided on one side of the slot 10, so that the cleaning liquid in the slot 10 can be discharged through the holes 13, preventing the cleaning liquid from accumulating in the slot 10. At the same time, a limiting groove 11 is provided at the top of the slot 10, and a limiting block 12 that fits into the limiting groove 11 is slidably connected in the limiting groove 11. The limiting block 12 is fixedly connected to the top of the silencer box 9. The setting of the limiting groove 11 and the limiting block 12 allows the silencer box 9 to move within the first housing 1 according to a predetermined trajectory, thereby ensuring the stability of the silencer box 9 during movement.

[0034] Meanwhile, a filter cover plate 14 is connected to the surface of the filter frame 7 via a hinge, and the filter cover plate 14 and the filter frame 7 are connected by a latch. Therefore, the filter cover plate 14 can be opened and closed by the latch. When the filter cover plate 14 is open, the compressor crankshaft to be cleaned can be placed into the filter frame 7. After the filter cover plate 14 is closed, the compressor crankshaft inside the filter frame 7 can be prevented from falling out during the cleaning process, thus affecting the cleaning of the compressor crankshaft. The surfaces of both the filter frame 7 and the filter cover plate 14 are provided with a rubber layer 15, which can protect the compressor crankshaft and prevent it from bumping against the filter frame 7 during the rotation of the filter frame 7, thus affecting the cleaning.

[0035] In this embodiment, during the cleaning process of the compressor crankshaft, after the compressor crankshaft is placed in the filter frame 7, the filter cover plate 14 is placed on top. Since the height of the compressor crankshaft matches the distance between the filter frame 7 and the filter cover plate 14, the filter cover plate 14 can press and fix the compressor crankshaft. Furthermore, the surfaces of both the filter frame 7 and the filter cover plate 14 are provided with a rubber layer 15, which increases the friction between the compressor crankshaft and the filter frame 7 and the filter cover plate 14. This prevents the compressor crankshaft from shaking when the filter frame 7 rotates in the horizontal and vertical directions, thus avoiding collisions between the compressor crankshafts that could affect cleaning and use.

[0036] Based on the above structure, although embodiments of the present utility model have been shown and described in this embodiment, these specific embodiments are merely explanations of the present utility model and are not intended to limit the utility model. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
