Description

Technical Field

[0001] This utility model relates to the technical field of chemical equipment, and in particular to an oil mist treatment device for a lubricating oil system. Background Technology

[0002] The oil mist treatment device for lubrication systems is a specialized device used to treat the oil mist generated during machining processes. Oil mist mainly originates from the evaporation or splashing of cutting fluids and lubricating oils used in machining at high temperatures, forming small oil droplets. This oil mist not only pollutes the working environment but may also affect worker health and equipment operation.

[0003] Existing patent publication number CN219912635U discloses an oil mist treatment device for a lubricating oil system, including a lubricating oil tank, a first oil mist fan, a filter, and a second oil mist fan. The filter contains a filter element with coalescing and separation functions. The lubricating oil tank is connected to the filter via an inlet pipe. The first oil mist fan is mounted on the filter inlet pipe. The filter has a vent pipe, and the second oil mist fan is mounted on the vent pipe. The filter also has a return oil pipe connected to the lubricating oil tank. The advantages of this invention are: avoiding filter damage and pipe blockage caused by insufficient oil mist separation; improving lubricating oil utilization; easy on-site maintenance; high operational reliability; and significantly reducing production costs.

[0004] Existing technology collects oil mist through the filter inlet pipe. However, when the oil mist passes through the filter inlet pipe, a large amount of oil mist remains on the inner wall surface of the filter inlet pipe. Oil particles in the oil mist may deposit on the inner wall of the pipe, causing contamination of the inner wall. Long-term accumulation may affect the cleanliness of the pipe and the hygiene of the working environment. Some chemicals in the oil mist may react with the inner wall of the pipe, causing corrosion of the inner wall of the pipe, affecting the service life and safety of the pipe. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide an oil mist treatment device for a lubricating oil system, which aims to solve the problem that "existing technologies collect oil mist through the filter inlet pipe, but when the oil mist passes through the filter inlet pipe, a large amount of oil mist remains on the inner wall surface of the filter inlet pipe, and oil particles in the oil mist may be deposited on the inner wall of the pipe, causing pollution of the inner wall of the pipe. Long-term accumulation may affect the cleanliness of the pipe and the hygiene of the working environment. Some chemical substances in the oil mist may react with the inner wall of the pipe, causing corrosion of the inner wall of the pipe, affecting the service life and safety of the pipe."

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A lubricating oil system oil mist treatment device, comprising:

[0010] The main unit includes an oil mist collection pipe, an air inlet pipe is installed on one side surface of the oil mist collection pipe, and a connecting flange is fixedly connected to the upper side surface of the oil mist collection pipe.

[0011] The cleaning unit includes a motor fixedly connected to an oil mist collection pipe. A rotating shaft is fixedly connected to the output end of the motor, and the surface of the rotating shaft is rotatably connected to the oil mist collection pipe. A bevel gear is fixedly connected to the other end of the rotating shaft, and a bevel gear is meshed with one side of the bevel gear. A rotating shaft is fixedly connected to the lower surface of the bevel gear, and two sets of connecting rods are fixedly connected to one side of the rotating shaft. A scraper is fixedly connected to the other end of the two sets of connecting rods, and the scraper is rotatably connected to the inner wall surface of the oil mist collection pipe. A protective sleeve is rotatably connected to the surface of the rotating shaft, and the protective sleeve is rotatably connected to the rotating shaft. Support plates are fixedly connected to both sides of the protective sleeve, and both support plates are fixedly connected to the inner wall surface of the oil mist collection pipe. A filter assembly is provided on the lower side of the protective sleeve.

[0012] As a preferred embodiment of the lubricating oil system oil mist treatment device of the present invention, the filter assembly includes a filter plate rotatably connected to the rotating shaft two, and the outer surface of the filter plate is fixedly connected to the oil mist collection pipe. The lower surface of the filter plate is rotatably connected to a scraper two, and one end of the scraper two is fixedly connected to the rotating shaft two.

[0013] As a preferred embodiment of the lubricating oil system oil mist treatment device of the present invention, the filter plate is hemispherical, the scraper is semi-circular, and the upper surface of the scraper is in close contact with the lower surface of the filter plate.

[0014] As a preferred embodiment of the lubricating oil system oil mist treatment device of the present invention, the lower end of the oil mist collecting pipe is detachably connected to a collecting tank, the inner wall surface of the oil mist collecting pipe is movably connected to the surface of the collecting tank, and a rubber ring is slidably connected to the outer surface of the collecting tank, and the rubber ring is fixedly connected to the lower surface of the oil mist collecting pipe.

[0015] As a preferred embodiment of the lubricating oil system oil mist treatment device of the present invention, the two sides of the collection tank are fixedly connected with fixing blocks, and the surfaces of the fixing blocks are rotatably connected with rotating buckles.

[0017] The beneficial effects of this utility model are:

[0018] 1. The motor, powered by a power source, drives the rotating shaft one to rotate inside the oil mist collection tube. The bevel gear one, fixedly connected to the rotating shaft one, drives the meshing bevel gear two to rotate. The rotating shaft two, fixedly connected to the bevel gear two, drives the connecting rod to rotate synchronously. This causes the connecting rod, fixedly connected to the rotating shaft two, to drive the scraper one to rotate and scrape the inner wall surface of the oil mist collection tube, scraping off the lubricating oil from the inner wall surface. At the same time, the filter plate fixedly connected inside the oil mist collection tube performs coarse filtration of the oil mist, which can effectively reduce the pressure of subsequent filter filtration. Furthermore, the scraper two, fixedly connected to the rotating shaft two, rotates and scrapes the lower surface of the filter plate, preventing oil stains from remaining on the surface of the filter plate and affecting filtration. This keeps the inner wall surface of the oil mist collection tube clean and effectively extends the service life of the oil mist collection tube.

[0019] 2. The oil and lubricating oil cleaned by the scraper and filtered by the filter plate will fall into the inner wall of the collection tank along the inner wall of the oil mist collection pipe. Then lift the collection tank up and rotate the rotating buckle on the surface of the fixing block to disengage the rotating buckle from the surface of the clip, thereby removing the collection tank from the inside of the oil mist collection pipe for easy cleaning.

[0031] The main unit 100 includes an oil mist collection pipe 101, an air inlet pipe 102 is installed on one side surface of the oil mist collection pipe 101, and a connecting flange 103 is fixedly connected to the upper surface of the oil mist collection pipe 101 for connecting a filter. The oil mist collection pipe 101 and the air inlet pipe 102 are interconnected.

[0032] The cleaning unit 200 includes a motor 201 fixedly connected to an oil mist collection pipe 101. A rotating shaft 202 is fixedly connected to the output shaft of the motor 201, and the surface of the rotating shaft 202 is rotatably connected to the oil mist collection pipe 101. A bevel gear 203 is fixedly connected to the other end of the rotating shaft 202, and a bevel gear 204 meshes with one side of the bevel gear 203. A rotating shaft 205 is fixedly connected to the lower surface of the bevel gear 204, and two sets of connecting rods 206 are fixedly connected to one side of the rotating shaft 205. A scraper 207 is fixedly connected to the other end of the two sets of connecting rods 206, and the scraper 207 is flush with the inner wall surface of the oil mist collection pipe 101. A protective sleeve 209 is rotatably connected to the surface of the rotating shaft 205, and the protective sleeve 209 is rotatably connected to the rotating shaft 202. Support plates 210 are fixedly connected to both sides of the protective sleeve 209, and the support plates 210 are fixedly connected to the inner wall surface of the oil mist collection pipe 101. A filter assembly 208 is provided on the lower side of the protective sleeve 209. The protective sleeve 209 can not only provide oil protection for the bevel gear 203 and bevel gear 204, but also support the rotating shaft 205. The motor 201 can drive the scraper 207 to rotate on the inner wall surface of the oil mist collection pipe 101, scraping off the oil stains that remain on the inner wall surface of the oil mist collection pipe 101.

[0033] The filter assembly 208 includes a filter plate 208a rotatably connected to the second rotating shaft 205, and the outer surface of the filter plate 208a is fixedly connected to the oil mist collection pipe 101. A scraper 208b is rotatably connected to the lower surface of the filter plate 208a, and one end of the scraper 208b is fixedly connected to the second rotating shaft 205. The filter plate 208a performs coarse filtration of the oil mist to reduce the filtration burden of the filter, and the scraper 208b can clean the filter plate 208a.

[0034] Furthermore, the filter plate 208a has a hemispherical design, and the scraper 208b has a semi-circular design. The upper surface of the scraper 208b is in close contact with the lower surface of the filter plate 208a, which facilitates the downward flow of the lubricating oil filtered by the filter plate 208a.

[0035] Furthermore, the lower end of the oil mist collecting pipe 101 is detachably connected to a collecting tank 214. The inner wall surface of the oil mist collecting pipe 101 is movably connected to the surface of the collecting tank 214. A rubber ring is slidably connected to the outer surface of the collecting tank 214, and the rubber ring is fixedly connected to the lower surface of the oil mist collecting pipe 101, which has a sealing function, collects the oil sludge scraped off by the scraper 207, and can also collect the lubricating oil coarsely filtered by the filter plate 208a.

[0036] Furthermore, both sides of the collection tank 214 are fixedly connected to fixing blocks 211, and the surfaces of the fixing blocks 211 are rotatably connected to rotating buckles 212. The surfaces of the two sets of rotating buckles 212 are engaged with buckles 213, and the buckles 213 are fixedly connected to the oil mist collection pipe 101.

[0038] During operation, the motor 201, powered by the power supply, drives the rotating shaft 202 to rotate inside the oil mist collection pipe 101. The bevel gear 203, fixedly connected to the rotating shaft 202, drives the meshing bevel gear 204 to rotate. The rotating shaft 205, fixedly connected to the bevel gear 204, drives the connecting rod 206 to rotate synchronously. This causes the connecting rod 206, fixedly connected to the rotating shaft 205, to drive the scraper 207 to rotate and scrape the inner wall surface of the oil mist collection pipe 101, removing the lubricating oil. Simultaneously, the filter plate 208a, fixedly connected inside the oil mist collection pipe 101, performs coarse filtration of the oil mist, effectively reducing the oil mist that passes through subsequent filters. The pressure of the filter, and the scraper 208b fixedly connected to the rotating shaft 205 rotates and scrapes the lower surface of the filter plate 208a, so that the surface of the filter plate 208a will not be covered with oil stains, which will affect the filtration. The oil stains cleaned by the scraper 207 and the lubricating oil filtered by the filter plate 208a will fall into the inner wall of the collection tank 214 along the inner wall of the oil mist collection pipe 101. Then the collection tank 214 is lifted up, and then the rotating buckle 212 is rotated on the surface of the fixing block 211, which can disengage the rotating buckle 212 from the surface of the buckle 213, thereby removing the collection tank 214 from the inside of the oil mist collection pipe 101 for easy cleaning of the collection tank 214.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
