Description

Technical Field

[0001] This invention relates to the field of casting cleaning equipment technology, and specifically to a deep cleaning device for castings. Background Technology

[0002] After die castings are manufactured, it is usually necessary to clean impurities from the surface of the castings. In the existing technology, ultrasonic cleaning is a common and efficient cleaning method for castings. During cleaning, the castings are placed in a cleaning chamber, and the cavitation effect generated by ultrasonic waves is used for cleaning.

[0003] During the cleaning process, impurities on the surface of the casting are removed by ultrasonic cleaning. However, solid impurities mainly settle to the bottom of the cleaning tank by gravity. Because solid impurities are disturbed by the ultrasonic waves, the settling time of solid impurities is longer, causing them to remain suspended in the cleaning solution for an extended period. These solid impurities are prone to re-adhere to the cleaned casting surface, causing secondary contamination. Furthermore, when cleaning castings with grooves on their surfaces, the removed solid impurities often fall into the grooves, resulting in incomplete cleaning. Summary of the Invention

[0004] The purpose of this invention is to design a deep cleaning device for castings that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A deep cleaning device for castings includes an ultrasonic cleaner and a recovery tank. The ultrasonic cleaner has a cleaning chamber with a base box for placing the castings inside. A cleaning ring is connected to the top of the base box and is arranged in a ring. A cover is detachably attached to the top of the cleaning ring. Both the base box and the cover have drainage holes. The two sides of the cleaning ring are rotatably connected to the inner wall of the cleaning chamber via a first rotating shaft and a second rotating shaft. The inner wall of the cleaning ring has a plurality of cleaning ports arranged in a ring for spraying cleaning fluid. A servo motor is provided on the outer wall of the cleaning chamber and is drivenly connected to the first rotating shaft. The bottom of the cleaning chamber is connected to the recovery tank via a recovery pipe.

[0006] Furthermore, the bottom box is provided in a plurality of units, which are evenly distributed along the length of the cleaning tank.

[0007] Furthermore, the cleaning ring has a hollow inner cavity, the cleaning port communicates with the inner cavity, the second rotating shaft has a pipe communicating with the inner cavity, and the end of the second rotating shaft away from the cleaning ring passes through the side wall of the cleaning tank and is fixedly connected to a rotary joint.

[0008] Furthermore, the inside of the recycling tank is equipped with a filter screen plate, the drain port of the recycling pipe is located below the filter screen plate, a liquid pump is fixedly installed on the top of the recycling tank, the liquid pump's suction pipe passes into the inside of the recycling tank, the liquid inlet of the suction pipe is located above the filter screen plate, the drain port of the liquid pump is fixedly connected to a pipeline splitter, and the branch drain ports of the pipeline splitter are fixedly connected to the inlet of the rotary joint through branch pipes.

[0009] Furthermore, the end of the first rotating shaft away from the cleaning ring passes through the side wall of the cleaning tank and is fixedly connected to a sprocket. Several sprockets are connected by chain meshing. One of the ends of the first rotating shaft away from the cleaning ring is fixedly connected to the rotating end of the servo motor through a coupling.

[0010] Furthermore, the lower part of the inside of the recycling tank, located below the filter screen, has a conical structure, and the bottom of the recycling tank is connected to a discharge pipe.

[0011] Furthermore, the bottom box and the lid have the same structure, both being a hemispherical structure formed by fixing several arc-shaped plates in a circumferential array, with the gap between two adjacent arc-shaped plates being a perforation.

[0012] Furthermore, the bottom of the box cover is fixedly connected to an inner ring plate arranged in a circumferential manner, and the top of the cleaning ring is fixedly connected to an outer ring plate arranged in a circumferential manner. The outer wall of the inner ring plate is provided with an external thread, and the inner wall of the outer ring plate is provided with an internal thread that mates with the external thread.

[0013] Furthermore, cushioning pads are provided on the inner walls of the bottom box, the cleaning ring, and the box cover.

[0014] The beneficial effects of this invention are as follows: By setting a rotatable base and cover, along with the cleaning port on the cleaning ring, the castings inside the cleaning chamber can be tumbled and rinsed with cleaning fluid after ultrasonic cleaning. This effectively removes solid impurities that re-adhere to the surface of the castings and impurities in the grooves, thus performing a secondary cleaning of the castings to achieve a deep cleaning effect and avoid the problems of secondary pollution and incomplete cleaning.

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] like Figure 1 , Figure 4 and Figure 6 As shown, a deep cleaning device for castings includes an ultrasonic cleaner 1 and a recovery tank 2. The cleaning chamber 3 of the ultrasonic cleaner 1 has a base box 4 for placing the castings inside. The top of the base box 4 is connected to a cleaning ring 5 arranged in a ring. The top of the cleaning ring 5 is detachably covered with a cover 6. Both the base box 4 and the cover 6 are provided with drainage holes. The two sides of the cleaning ring 5 are rotatably connected to the inner wall of the cleaning chamber 3 through a first rotating shaft 7 and a second rotating shaft 8. The inner wall of the cleaning chamber 3 is provided with bearings to achieve rotatable connection with the first rotating shaft 7 and the second rotating shaft 8. The inner wall of the cleaning ring 5 has a plurality of cleaning ports 9 arranged in a ring for spraying cleaning fluid. The outer wall of the cleaning chamber 3 is provided with a servo motor 10 that is drivenly connected to the first rotating shaft 7. The bottom of the cleaning chamber 3 is connected to the recovery tank 2 through a recovery pipe 11.

[0019] In this embodiment, as Figure 4As shown, there are five bottom boxes 4, which are evenly distributed along the length of the cleaning box 3, allowing multiple castings to be cleaned simultaneously, thus improving cleaning efficiency.

[0020] like Figure 2 and Figure 6 As shown, the interior of the cleaning ring 5 is a hollow inner cavity 12, and the cleaning port 9 is connected to the inner cavity 12. The interior of the second rotating shaft 8 is provided with a pipeline connected to the inner cavity 12. The end of the second rotating shaft 8 away from the cleaning ring 5 passes through the side wall of the cleaning tank 3 and is fixedly connected to a rotary joint 13. The rotary joint 13 can realize the continuous supply of cleaning fluid without affecting the rotation of the cleaning ring 5.

[0021] like Figure 1 , Figure 2 and Figure 7 As shown, the inside of the recovery tank 2 is equipped with a filter screen plate 14, and the drain port of the recovery pipe 11 is located below the filter screen plate 14. In actual use, a pump body can be installed on the recovery pipe 11 as needed to assist in extracting the cleaning liquid in the cleaning tank 3. A liquid pump 15 is fixedly installed on the top of the recovery tank 2. The liquid pump 15's suction pipe 16 passes into the inside of the recovery tank 2, and the liquid inlet of the suction pipe 16 is located above the filter screen plate 14. The drain port of the liquid pump 15 is fixedly connected to a pipeline splitter 17. The branch drain ports of the pipeline splitter 17 are fixedly connected to the inlet of the rotary joint 13 through branch pipes. After the recovered cleaning liquid is filtered by the filter screen plate 14, it can be transported to the inner cavity 12 of the cleaning ring 5 by the liquid pump 15 to realize the recycling of the cleaning liquid.

[0022] like Figure 3 and Figure 4 As shown, the end of the first rotating shaft 7 away from the cleaning ring 5 passes through the side wall of the cleaning box 3 and is fixedly connected to a sprocket 18. Five sprockets 18 are connected by a chain 19. One end of the first rotating shaft 7 away from the cleaning ring 5 is fixedly connected to the rotating end of the servo motor 10 through a coupling. After the servo motor 10 is started, it drives the five cleaning rings 5 ​​to rotate synchronously through the transmission of the sprocket 18 and the chain 19, ensuring that multiple castings are cleaned synchronously. The servo motor 10 is electrically connected to a controller, and the number of rotations of the rotating end of the servo motor 10 can be set by the controller. This is existing technology and will not be described in detail here. When the servo motor 10 stops, the box cover 6 can be kept directly above the bottom box 4, which is convenient for the placement and removal of castings.

[0023] like Figure 7 As shown, the lower part of the inside of the recovery tank 2, located below the filter screen plate 14, has a conical structure. The bottom of the recovery tank 2 is connected to the discharge pipe 20. The conical structure facilitates the concentrated settling of solid impurities. The precipitated impurities can be discharged by opening the valve on the discharge pipe 20.

[0024] like Figure 5As shown, the bottom box 4 and the lid 6 have the same structure. They are both hemispherical structures formed by sixteen arc-shaped plates 21 fixed in a circumferential array. The gap between two adjacent arc-shaped plates 21 is a leakage hole. The hemispherical structure can ensure the smooth rolling of the casting, and the leakage hole can allow the cleaning fluid to flow smoothly and solid impurities to pass through.

[0025] like Figure 5 As shown, the bottom of the box cover 6 is fixedly connected to an inner ring plate 22 arranged around it, and the top of the cleaning ring 5 is fixedly connected to an outer ring plate 23 arranged around it. The outer wall of the inner ring plate 22 is provided with an external thread, and the inner wall of the outer ring plate 23 is provided with an internal thread that mates with the external thread. The box cover 6 and the cleaning ring 5 are detachably fixed through the threaded connection, which facilitates the placement and removal of the casting.

[0026] like Figure 5 As shown, buffer pads 24 are provided on the inner walls of the base box 4, cleaning ring 5 and box cover 6. The buffer pads 24 can be made of silicone, which can effectively buffer the impact force on the casting during the rolling process and avoid the surface of the casting from being bumped and damaged.

[0027] Working principle: In use, first place the casting to be cleaned in the base box 4, then fix the box cover 6 to the top of the cleaning ring 5 with a threaded connection to secure the casting. Next, inject cleaning fluid into the cleaning tank 3 so that the cleaning fluid covers the casting, start the ultrasonic cleaner 1, and use the cavitation effect of ultrasound to clean the casting, remove impurities from the surface of the casting, and perform the first cleaning.

[0028] After ultrasonic cleaning, the valve on the recovery pipe 11 is opened to discharge the cleaning solution in the cleaning tank 3 into the recovery tank 2. Solid impurities in the cleaning solution are filtered by the filter screen 14 and settle at the bottom of the recovery tank 2. Then, the number of rotations of the servo motor 10 is set and the servo motor 10 is started. The servo motor 10 drives the cleaning ring 5 to rotate through the sprocket 18 and chain 19, which in turn causes the castings in the bottom box 4 and the box cover 6 to tumble continuously. At the same time, the liquid pump 15 is started, and the liquid pump 15 draws out the filtered cleaning solution from the recovery tank 2 and delivers it to the inner cavity 12 of the cleaning ring 5 through the pipeline distributor 17 and the rotary joint 13. Finally, it is sprayed out from the cleaning port 9 to rinse the surface of the tumbling castings and the groove, effectively cleaning the solid impurities that re-adhere to the surface of the castings and the impurities in the groove, thereby performing a secondary cleaning of the castings to achieve a deep cleaning effect and avoid the problems of secondary pollution and incomplete cleaning.

[0029] After rinsing, turn off the servo motor 10 and the liquid pump 15, open the box cover 6 and take out the cleaned casting. Periodically open the valve on the discharge pipe 20 to discharge the solid impurities settled at the bottom of the recovery tank 2 for subsequent recycling processing.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
