[0002] Steam turbine lubricating oil purification equipment is a device that can filter iron filings in lubricating oil. The purification equipment is equipped with magnetic rods that can effectively adsorb iron filings. In the existing technology, after long-term use, the magnetic rods in the purification equipment need to be frequently disassembled and cleaned, which makes the convenience of use less than ideal.

[0003] For example, patent publication number CN211692585U specifically describes a turbine lubricating oil tank return oil purification device in the field of turbine oil systems. It includes a housing, a fixed lifting slide rail, a filter screen, an adsorption magnetic rod, and fixing bolts. The fixed lifting slide rail is located on the outer peripheral wall of the housing and is installed on the return oil side of the main oil tank via a slide rail. The filter screen is installed on the housing, and the adsorption magnetic rod is installed on the filter screen. Both the filter screen and the adsorption magnetic rod are connected to the housing via fixing bolts. This device has a simple structure, high operability, and the filter screen and adsorption magnetic rod can be replaced at any time, greatly reducing labor intensity and solving the current problem of poor filtration of return oil impurities. It also significantly reduces operating and maintenance costs. However, this purification device suffers from the problem that the magnetic rod requires frequent disassembly and cleaning after prolonged use, making its ease of use less than ideal.

[0007] Preferably, the rotating shaft is located at the top center of the switching plate, and the switching plate is rotatably connected to the inner wall of the housing via the rotating shaft, so that the switching plate can rotate and thus switch the positions of the two electromagnets.

[0008] Preferably, the worm gear meshes with the worm, and the output shaft end of the drive motor is connected to the rotating shaft via the worm gear and the worm, so that the drive motor can drive the rotating shaft to rotate.

[0009] Preferably, the two ends of the U-shaped frame are connected through the connecting plate and extend to the bottom of the connecting plate, and the spring is sleeved on the U-shaped frame so that the U-shaped frame can be reset by the spring.

[0010] Preferably, the first electric push rod is fixedly installed on one side of the top of the housing, and the output shaft end of the first electric push rod passes through the housing and extends into the interior of the housing, so that the first electric push rod can push the U-shaped frame to move.

This eliminates the need for frequent disassembly and replacement, effectively improving the ease of use.

[0015] 2. This turbine lubricating oil purification equipment uses an embedded block to embed into an embedded groove and a collection box to install on a mounting frame. This allows the scraper to easily send iron filings into the collection box for collection, making it convenient to collect iron filings. Attached Figure Description

A worm 204 is provided on one side of the worm gear 203, and a drive motor 205 is fixedly connected to the end of the worm 204. The rotating shaft 202 is located at the center of the top of the switching plate 201, and the switching plate 201 is rotatably connected to the inner wall of the housing 1 through the rotating shaft 202, so that the switching plate 201 can rotate, thereby switching the positions of the two electromagnets 212. The worm gear 203 meshes with the worm 204. The output shaft of the drive motor 205 is connected to the rotating shaft 202 via a worm gear 203 and a worm 204, enabling the drive motor 205 to drive the rotating shaft 202 to rotate. Connecting plates 206 are fixedly connected to both ends of the switching plate 201. A U-shaped frame 207 is slidably connected to the connecting plate 206. Mounting plates 208 are fixedly connected to both ends of the U-shaped frame 207. An electromagnet 212 is fixedly connected to the bottom of the mounting plate 208. A switch button connected to the electromagnet 212 is located on the top of the U-shaped frame 207, which can close the electromagnet 212 when pressure is applied. 2. To facilitate scraping off iron filings from the electromagnet 212, the electromagnet 212 is energized and magnetized when not under pressure. A spring 209 is provided on the U-shaped frame 207. Both ends of the U-shaped frame 207 penetrate the connecting plate 206 and extend to the bottom of the connecting plate 206. The spring 209 is sleeved on the U-shaped frame 207, allowing the U-shaped frame 207 to be reset using the spring 209. A first electric push rod 210 is provided on the top side of one side of the switching plate 201. The first electric push rod 210 is fixedly installed on one side of the top of the housing 1, and the first electric push rod 210... The output shaft end penetrates through the housing 1 and extends into the housing 1, so that the first electric push rod 210 can push the U-shaped frame 207 to move. The output shaft end of the first electric push rod 210 is fixedly connected to the push plate 211. A second electric push rod 213 is provided at the bottom of one side of the switching plate 201. The output shaft end of the second electric push rod 213 is fixedly connected to the scraper 214. The second electric push rod 213 is fixedly installed on the rear side of the housing 1. The scraper 214 matches the electromagnet 212, so that the scraper 214 can scrape off the iron filings on the surface of the electromagnet 212.

[0024] Please see Figure 1 and Figure 4The collection mechanism 4 includes a mounting frame 401, which is fixedly mounted on the housing 1. The mounting frame 401 has two embedding slots 402 and a collection box 403. Two embedding blocks 404 are fixedly connected to the end of the collection box 403. The cross-sectional shape of the embedding blocks 404 is T-shaped for easy replacement. One side of the collection box 403 has an opening that communicates with the inside of the housing 1, so that the scraper 214 can scrape off the iron filings. The bottom inner side of the collection box 403 is set as an inclined surface. The collection box 403 can be mounted on the mounting frame 401 by embedding the embedding blocks 404 into the embedding slots 402, so that the scraper 214 can send the iron filings into the collection box 403 for collection, making it convenient to collect the iron filings.

[0025] During operation, the geared motor drives the cylindrical filter screen 3 to rotate and sends iron filings to the top. The electromagnet 212 picks up the iron filings from the cylindrical filter screen 3, and then the drive motor 205 drives the worm gear 204 to rotate. The rotation of the worm gear 204 drives the worm wheel 203 to rotate, which in turn drives the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 drives the switching plate 201 to rotate, which in turn drives the connecting plate 206 to rotate, switching the positions of the two electromagnets 212 to maintain the continuous picking up and cleaning of iron filings. Then, the first electric push rod 210 drives the push plate 211 to move. The push plate 211 pushes the U-shaped frame 207 to move and de-energizes the electromagnet 212, bringing the electromagnet 212 into contact with the scraper 214. The second electric push rod 213 drives the scraper 214 to move, cleaning the iron filings on the electromagnet 212. This eliminates the need for frequent disassembly and replacement, effectively improving the ease of use.
