Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-impregnated bearing processing technology, and more specifically, to a waste recycling device for powder metallurgy oil-impregnated bearings. Background Technology
[0002] Powder metallurgy oil-impregnated bearings are self-lubricating bearings manufactured using powder metallurgy technology. They are made by mixing metal powders (such as iron, copper, aluminum, etc.) with appropriate amounts of lubricants (such as graphite, molybdenum disulfide, etc.) and then forming a bearing with a porous structure through processes such as pressing and sintering. Before use, the bearing is immersed in lubricating oil so that the lubricating oil fills the pores, thereby achieving the self-lubricating function. Waste generated during the production of powder metallurgy oil-impregnated bearings needs to be recycled.
[0003] A search revealed that Chinese Patent CN222153941U discloses a powder metallurgy production device for oil-impregnated bearings. This utility model, through the cooperation of a cleaning mechanism and a production mechanism, ensures the cleanliness of the workbench during the production of oil-impregnated bearings, effectively preventing the metal powder left on the workbench surface from affecting the subsequent production of oil-impregnated bearings, thus ensuring the quality of the oil-impregnated bearings. Furthermore, after production is completed, the oil-impregnated bearings with adsorbed metal powder are further cleaned, reducing the workload of subsequent cleaning.
[0004] When the above-mentioned patent is used, the vacuuming device is activated to absorb the metal powder into the collection chamber through the lower suction hole and the upper suction pipe. However, when the metal powder is covered with oil, the vacuuming device has difficulty sucking up the metal powder, making it inconvenient to separate the metal powder and difficult to effectively collect such metal powder, thus affecting the recycling efficiency. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste recycling device for oil-impregnated bearings in powder metallurgy, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste recycling device for oil-impregnated bearings in powder metallurgy, comprising a storage box and a box cover, wherein the box cover is locked to the top of the storage box by a snap fastener, a magnetizer is fixedly installed on one side of the storage box, and an adsorption assembly is provided on one side of the magnetizer, wherein the adsorption assembly comprises two iron cylinders, two iron rods, two insulating plates, two rotating shafts, a stepper motor, and a transmission mechanism, wherein one end of each of the two iron rods is fixedly connected to the two iron cylinders, and the other end of each of the two iron rods is movably connected to the storage box by bearings, both ends of the two insulating plates are fixedly connected to the two iron cylinders and the two rotating shafts, both of the two rotating shafts are movably connected to the storage box by bearings, and the two rotating shafts are connected to each other by a transmission mechanism, and the output shaft end of the stepper motor is fixedly connected to one of the rotating shafts.
[0007] Furthermore, a U-shaped plate is fixedly connected to the other side of the storage box, and one side of the U-shaped plate is fixedly connected to a stepper motor.
[0008] It can be seen that the above technical solution is designed to facilitate the support of the stepper motor.
[0009] Furthermore, a feed hopper is fixedly connected to the center of the top of the box cover.
[0010] Furthermore, a liquid outlet pipe is fixedly connected to the center of the bottom of the storage box, and a valve is fixedly installed on the liquid outlet pipe. Support frames are fixedly connected to the bottom of the storage box near both sides.
[0011] Furthermore, a filter screen is movably installed inside the storage bin, and both iron cylinders are located on top of the filter screen.
[0012] As can be seen, in the above technical solution, metal powder is separated by a filter.
[0013] Furthermore, a connecting plate is fixedly connected to the center of the bottom end of the filter screen, a hydraulic cylinder is fixedly connected to the bottom end of the connecting plate, a horizontal plate is fixedly connected to the bottom end of the hydraulic cylinder, and both sides of the horizontal plate are fixedly connected to the storage box.
[0014] It can be seen that the above technical solution is designed to facilitate the adjustment of the filter's position.
[0015] Furthermore, a discharge port is provided on the other side of the storage box, and a baffle is movably provided on one side of the discharge port, with the top of the baffle fixedly connected to the filter screen.
[0016] As can be seen, in the above technical solution, the discharge port is blocked by a baffle.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. This utility model uses a magnetizer to magnetize two iron rods, thereby magnetizing two iron cylinders. The two iron cylinders then adsorb metal powder from the waste. A stepper motor drives two insulating plates and two iron cylinders to rotate, which in turn causes the metal powder to be evenly adsorbed onto the two iron cylinders. The operation is simple and convenient for separating metal powder.
[0019] 2. This utility model filters waste through a filter screen, leaving metal powder on top of the screen. Opening the valve allows oil to be discharged from the storage tank through the outlet pipe. Closing the magnetizer demagnetizes the two iron cylinders, causing the metal powder to fall onto the filter screen. The hydraulic cylinder contracts, moving the connecting plate and filter screen downwards, positioning the filter screen at the bottom of the outlet to clean the metal powder. The structure is simple and easy to use. Attached Figure Description

[0028] Refer to the instruction manual appendix Figure 1-5 This embodiment of a waste recycling device for powder metallurgy oil-impregnated bearings includes a storage box 1 and a box cover 2. The box cover 2 is locked to the top of the storage box 1 by a buckle. A magnetizer 4 is fixedly installed on one side of the storage box 1. An adsorption assembly 6 is provided on one side of the magnetizer 4. The adsorption assembly 6 includes two iron cylinders 601, two iron rods 602, two insulating plates 603, two rotating shafts 604, a stepper motor 605, and a transmission mechanism 606. One end of each of the two iron rods 602 is fixedly connected to the two iron cylinders 601, and the other end of each of the two iron rods 602 is movably connected to the storage box 1 by a bearing. The two ends of each of the two insulating plates 603 are fixedly connected to the two iron cylinders 601 and the two rotating shafts 604, respectively. The two rotating shafts 604 are movably connected to the storage box 1 by a bearing, and the two rotating shafts 604 are connected to each other by the transmission mechanism 606. The output shaft end of the stepper motor 605 is fixedly connected to one of the rotating shafts 604.
[0029] Furthermore, a U-shaped plate 5 is fixedly connected to the other side of the storage box 1, and one side of the U-shaped plate 5 is fixedly connected to the stepper motor 605. A feed hopper 3 is fixedly connected to the center of the top of the box cover 2.
[0030] Furthermore, a liquid outlet pipe 8 is fixedly connected to the center of the bottom of the storage tank 1, and a valve 9 is fixedly installed on the liquid outlet pipe 8. Support frames 10 are fixedly connected to the bottom of the storage tank 1 near the two side edges. A filter screen 14 is movably installed inside the storage tank 1, and two iron cylinders 601 are located on top of the filter screen 14. A connecting plate 13 is fixedly connected to the center of the bottom of the filter screen 14. A hydraulic cylinder 12 is fixedly connected to the bottom of the connecting plate 13. A horizontal plate 11 is fixedly connected to the bottom of the hydraulic cylinder 12, and both sides of the horizontal plate 11 are fixedly connected to the storage tank 1. A discharge port is opened on the other side of the storage tank 1. A baffle 7 is movably installed on one side of the discharge port, and the top of the baffle 7 is fixedly connected to the filter screen 14.
[0031] In this process, waste is filtered through filter screen 14, with metal powder remaining on top of the screen. Two iron cylinders 601 adsorb the metal powder, preventing it from clogging the screen. Oil passes through the filter screen 14 and falls to the bottom of the storage tank 1. Valve 9 is opened, and the oil in the storage tank 1 is discharged through the outlet pipe 8. After the oil is separated, magnetizer 4 is turned off, causing the two iron cylinders 601 to demagnetize. The metal powder falls onto the filter screen 14, and hydraulic cylinder 12 is activated. The hydraulic cylinder on hydraulic cylinder 12 contracts, causing connecting plate 13 and filter screen 14 to move downward, positioning filter screen 14 at the bottom of the outlet to clean the metal powder on the screen. The structure is simple and easy to use. Similarly, hydraulic cylinder 12 extends, causing filter screen 14 and baffle 7 to move upward, with baffle 7 blocking the outlet.
[0032] The usage method of this embodiment is as follows:
[0033] In use, the storage bin 1 is placed at the bottom of the oil-impregnated bearing processing equipment. Waste material enters the storage bin 1 through the feed hopper 3. The magnetizer 4 is activated, and it magnetizes the two iron rods 602, thereby magnetizing the two iron cylinders 601. The two insulating plates 603 prevent the two rotating shafts 604 from being magnetized. The metal powder in the waste material is adsorbed by the two iron cylinders 601. The stepper motor 605 is activated, and it drives the two rotating shafts 604 to rotate through the transmission mechanism 606. The transmission mechanism 606 includes a belt and two pulleys, which are fixedly installed on the two rotating shafts 604, thereby driving the two insulating plates 603 and the two iron cylinders 601 to rotate. This allows the metal powder to be evenly adsorbed on the two iron cylinders 601. The operation is simple and convenient for separating metal powder.
