Description

Technical Field

[0001] The utility model relates to the technical field of oil pollution lubrication, in particular to an oil mist lubrication system for a biomass briquetting machine. Background Art

[0002] A lubrication system is a system that specially sprays lubricants for transmission components to ensure their smooth operation. The lubrication system is relatively common in daily life. Existing biomass briquetting machines also have a lubrication system. Although it can achieve a good lubrication effect, the lubrication systems of existing biomass briquetting machines on the market all use the form of pumping dry grease for lubrication. Dry grease is a viscous semi-solid and semi-liquid lubricating oil, and pumping is rather difficult. Especially in winter, the fluidity of dry grease is even worse, and the lubrication effect is average. The pressing wheel bearings of biomass briquetting machines are mostly in a horizontal state. When dry grease enters the pressing wheel bearings, a part of the dry grease will fall off, resulting in low utilization rate. The internal sealing method of existing biomass briquetting machines uses labyrinth ring seals. When the viscous semi-solid and semi-liquid lubricating oil pastes on the labyrinth ring seals, the adhered dust and impurities will affect their sealing effect and service life. When too much dry grease adheres to the bearings, it will cause poor heat dissipation of the bearings. Therefore, there is a problem of poor lubricating oil use effect in the lubrication systems of existing biomass briquetting machines on the market. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an oil mist lubrication system for a biomass briquetting machine, which solves the problems of large fuel consumption, incomplete utilization of oil fluid and formation of oil pollution adhering to the equipment in existing biomass briquetting machines.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: An oil mist lubrication system for a biomass briquetting machine includes an oil mist generator, a reduction gearbox and a briquetting machine forming chamber. An air source pipeline, an oil mist pipeline, a first oil pump and a second oil pump are connected to the oil mist generator. One end of the oil mist pipeline is connected to a jet injection distribution valve. An oil suction pipeline and an oil pipeline are connected to the jet injection distribution valve. A rotary joint is installed at one end of the oil pipeline. A motor is installed at the input end of the reduction gearbox. A pressing wheel assembly is rotatably arranged in the briquetting machine forming chamber. A pressing wheel bearing is installed between the pressing wheel assembly and the briquetting machine forming chamber.

[0005] The pressing wheel assembly includes a bearing cavity. A pair of bearings are arranged in the bearing cavity. An oil mist guiding nozzle is arranged in the bearing cavity and between the pair of bearings. An eccentric sleeve is installed on the pair of bearings. An eccentric sleeve oil mist path is installed in the eccentric sleeve. One end of the eccentric sleeve oil mist path is connected to an oil mist joint and the other end is connected to the oil mist guiding nozzle.

[0006] Preferably, a briquetting machine main shaft is rotatably installed in the forming chamber of the briquetting machine. The main shaft of the briquetting machine is connected to the output end of the reduction box. The rotary joint is rotatably connected to the main shaft of the briquetting machine. A pair of oil circuits are connected inside the rotary joint. The pair of oil circuits penetrate through the main shaft of the briquetting machine and extend into the forming chamber of the briquetting machine and are connected to the oil mist joint.

[0007] Preferably, a first solenoid valve, a pressure transmission filter, a pressure switch and a pressure gauge are installed on the air source pipeline.

[0010] Advantages

[0011] The present utility model provides an oil mist lubrication system for a biomass briquetting machine, which has the following advantages:

[0012] 1. The oil mist lubrication system generates micron-sized oil mist particles through an external compressed air and a secondary ultrasonic atomization process. The oil mist flow composed of the oil mist particles is sent to the lubrication parts that need it through pipelines, reasonably using the oil liquid without waste. The rotating parts are lubricated by the atomized oil mist particles, which can effectively save the consumption of lubricating oil. At the same time, it can ensure that most of the lubricating oil is just sprayed onto the rotating parts, without waste and without sticking too much dust and impurities.

[0013] 2. The atomized oil mist particles can well cover the bearing surface and will not cause accumulation problems, which helps the lubrication of the bearing and prevents heat accumulation. Brief Description of the Drawings
