Abstract
Description
Technical Field
[0001] The utility model relates to an anti-rust oil recovery device for high-frequency heat treatment, belonging to the technical field of anti-rust oil recovery. Background Art
[0002] Anti-rust oil is an oil solvent with reddish-brown appearance and anti-rust function. Anti-rust grease is composed of one or more anti-rust additives (also known as oil-soluble corrosion inhibitors) and their auxiliary additives added to the basic components of petroleum. It is easy to use, low cost, good effect, simple operation, and is used for indoor storage and transportation protection of various mechanical parts. The application method can be dip coating, spraying, and brushing. High-frequency heat treatment is a comprehensive process that heats, insulates, and cools the material in a certain medium to control its performance by changing the surface or internal structure of the material. After high-frequency heat treatment, the surface of the parts often has or produces scale, oil stains, salt residue and other dirt before and during the heat treatment, which affects the surface quality of the parts. Therefore, the surface of the parts must be cleaned in time. Common cleaning methods include immersion, boiling, pickling, sandblasting, shot blasting, etc.
[0003] In order to prevent rust after heat treatment, washing, sandblasting or shot blasting, commonly used anti-rust methods include immersion in anti-rust liquid, immersion in anti-rust oil, etc. A large amount of anti-rust oil is needed in this process, so the effective recovery of anti-rust oil can effectively save production costs. In previous technologies, the recovery of anti-rust oil is generally carried out manually, but the efficiency of manual recovery is low and the workload is large. There are still many impurities in the used waste oil that cannot be removed. Therefore, an anti-rust oil recovery device with automatic recovery function and automatic separation of impurities is particularly critical, which can greatly reduce labor costs and save production costs, thereby reducing production time and improving production efficiency.

[0013] (3) Beneficial effects

Most of the anti-rust oil containing residues will flow through a funnel and a pipeline into an anti-rust oil recovery box, thereby reducing a large amount of waste.
[0016] The utility model discloses a rust-proof oil recovery device for high-frequency heat treatment, which is provided with three layers of filter screens. When the rust-proof oil enters the device, most of the large metal particles and large particle impurities can be filtered out. After entering the centrifuge, the light-weight rust-proof oil will be thrown to the inner wall of the sleeve by the high-speed rotating centrifuge and then flow into the rust-proof oil recovery box along the funnel. In this process, some small large-mass impurities will be left in the metal partition screen of the centrifuge. A magnet is arranged under the last layer of the recovery box to absorb metal powder. Such a design greatly improves the purity of the recovered rust-proof oil and has a better filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As shown in the figure, this is a high-frequency heat treatment anti-rust oil recovery device, which has a centrifuge device and a filtering structure installed inside.
[0027] It is characterized in that a first layer of large-diameter filter screen 2 is installed at the bottom of the workbench 19, a large-diameter funnel 1 is connected directly below the first layer of large-diameter filter screen 2, a second layer of small-diameter filter screen 3 is connected directly below the large-diameter funnel 1, and intersects with the outer sleeve of the centrifuge 4, two small-diameter funnels 8 are connected on the left and right sides below the centrifuge 4, a third layer of filter screen 9 is connected directly below the small-diameter funnel 8, and an anti-rust oil recovery box 10 is located below the small-diameter funnel 8. The anti-rust oil recovery box 10 is placed on a push-pull drawer 11, and a slide rail 12 is connected below the push-pull drawer 11 for sliding connection. The engine 14 is fixedly connected to the positioning shaft 16, and the positioning shaft 16 is limited by the shaft limit module 13 below. The left side of the engine 14 is controlled by the operating box 15 through a wire;
[0028] When in use, first turn on the engine switch through the operating box 15, turn on the centrifuge in the equipment, spray and soak the anti-rust oil on the workbench 19 after high-frequency quenching, and the excess anti-rust oil and impurities used will flow into the interior of the device along the large-diameter funnel 1, and the large particles of impurities will be left on the first layer of large-diameter filter screen 2. The liquid after the first layer of filtration enters the second layer of small-diameter filter screen 3 in the large-diameter funnel 1 and enters the liquid receiving interface 28 of the centrifuge through the pipeline. At the same time, the high-speed rotation of the shaft will push the liquid in the liquid receiving interface 28 along the large-diameter funnel 1. The rust-proof oil is sprayed onto the metal filter sleeve 6 through the drainage port 29. Because the quality of the rust-proof oil is low, the rust-proof oil will spray onto the outer wall of the outermost sleeve 4 of the centrifuge through the inner wall of the conical sleeve 5 under the high-speed rotation of the centrifuge. Some of the impurities with higher quality are retained at the bottom of the metal filter sleeve 6, some are blocked by the blocking module 17, and some are blocked by the blocking pouring port 26 above the sleeve. The rust-proof oil sprayed on the inner wall flows along the inner wall into the small-diameter funnels 8 on both sides and enters the rust-proof oil recovery box 10 through the third filter screen 9. The rust-proof oil recovery box 10 is placed on a push-pull drawer 11, which is covered with a magnetic gasket 25 to prevent the presence of fine magnetic particles in the rust-proof oil after three filtrations.
[0029] When recycling the anti-rust oil, it is necessary to open the switch 20 on the drawer, open the drawer, directly take out the anti-rust oil recovery box 10, and pour out the filtered anti-rust oil. The drawer is connected to the device in the form of a slide rail, and there are multiple pulleys 23 on both sides of the left and right sides of the push-pull drawer 11, with two rows on each side, which greatly improves the stability and convenience of the sliding structure.
[0030] The cover above the outermost sleeve of the device is connected to the body by a thread 18, and the cover and the body of the centrifuge are also connected by a thread 18. When the device is regularly maintained or cleaned daily, you only need to unscrew the top cover. The conical sleeve 5 and the metal filter sleeve 6 inside the centrifuge are connected by four large-diameter external thread screws 21. When cleaning, unscrew the large-diameter external thread screws 21 to remove the two sleeves and clean their outer walls. There are three layers of filter screens in this device, all of which can be manually disassembled. There is a circle of circular platforms 30 on each filter funnel and workbench for placing filter screens 31. The filter screen can be replaced and cleaned.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
