Description

Technical Field

[0001] The utility model relates to the technical field of concentrator lubrication, in particular to a transmission gear lubrication device for a peripheral transmission concentrator. Background Art

[0002] A peripheral drive thickener is a thickening device consisting of a circular thickening tank and a rake scraper. In the peripheral drive thickener, solid particles in the thickening tank settle under gravity, separating the solids and liquids. The rake scraper continuously scrapes the sludge deposited at the bottom of the thickening tank and discharges it through a discharge port at the center of the tank, while clarified water overflows from the top of the thickening tank. Lubrication of the transmission gears of a peripheral drive thickener is crucial to ensuring proper operation and extending its service life. Its primary purpose is to reduce friction and wear between the gears, minimizing energy loss and improving transmission efficiency. It also reduces noise and vibration and prevents corrosion and oxidation.

[0003] After searching, a Chinese utility model patent with announcement number CN216143146U was found, and its name is continuous lubrication device for peripheral transmission concentrator track and transmission gear. The oil in the oil box flows to the oil leakage port and is evenly distributed on the entire cotton rope. Through the cotton rope, the oil continuously and frequently drips on the gears and the top of the travel wheel. The oil drips on the gears and travel wheels in the form of drops through the cotton rope. After passing through the gears and travel wheels, an oil film is formed on the rack and track, so that the gears and racks, tracks and travel wheels are well and evenly lubricated. This lubrication method not only replaces manual lubrication and maintenance operations, but also makes the lubricating oil evenly distributed, and makes the lubrication between the tracks and travel wheels, and the gears and racks more sufficient, reducing the safety risks during manual lubrication operations. In addition, it has a simple structure and is easy to operate.

[0004] However, during use, it was found that although the method of using cotton rope to drip lubricating oil can achieve continuous lubrication, the control of the amount of lubricating oil is not precise enough. Too much lubricating oil causes a certain amount of waste, and too little lubricating oil cannot provide sufficient lubrication effect. Long-term operation is easy to cause damage to the gears and affect the service life of the gears. During long-term operation, the gears and travel wheels will generate a lot of heat, and the lubricating oil dripping from the cotton rope may not be able to take away the heat in time and effectively, resulting in poor heat dissipation effect of the lubricating oil, which is not conducive to the use of lubrication of the transmission gears of the peripheral transmission concentrator.

During long-term operation, the gears and traveling wheels will generate a large amount of heat, and the lubricating oil dripping from the cotton rope may not be able to take away the heat in a timely and effective manner, resulting in poor heat dissipation effect of the lubricating oil, which is not conducive to the use of peripheral transmission concentrator transmission gear lubrication.

A motor 8 is installed on the top surface of the bracket 2 near the edge through a mounting seat, and a reducer 9 is coaxially connected to the output shaft of the motor 8. The reducer 9 is installed on the top surface of the bracket 2, and a sealing box 10 is rotatably connected to the outer peripheral wall of the output shaft of the reducer 9.

One end of the rotating shaft 6 located in the middle passes through the outer wall of the sealed box 10 and extends to the inside. The outer peripheral wall of the rotating shaft 6 located in the middle is rotatably connected to the sealed box 10, and the second gear 1103 is sleeved on the outer peripheral wall of the rotating shaft 6 extending to the inside of the sealed box 10; the output shaft of the reducer 9 drives the first gear 1102 to rotate, so that the first gear 1102 is meshed and transmitted to the chain 1101 for synchronous rotation, and the chain 1101 is meshed and transmitted to the second gear 1103 for synchronous rotation.

[0034] The bottom surface of the sealed box 10 is inclined, and a liquid outlet 13 is provided at the lower end of the left wall of the sealed box 10. A one-way valve oil filling pipe 14 is connected to the right wall of the sealed box 10; the lubricating oil used to lubricate the transmission gears of the peripheral transmission concentrator is transported to the interior of the sealed box 10 through the oil filling pipe 14.

[0035] The lubrication assembly 12 includes a reflux box 1201, one side of which is connected to the liquid outlet 13. The reflux box 1201 is installed on the outer wall of the lower end of the sealing box 10. An oil pump 1203 is installed on the top surface of the reflux box 1201 through a mounting seat. The input end of the oil pump 1203 is connected to the interior of the sealing box 10; the lubricating oil enters the interior of the reflux box 1201 through the liquid outlet 13.

[0036] The output end of the oil pump 1203 is connected to the oil filter 1204, and the output end of the oil filter 1204 is connected to the cooling metal pipe 1205; the lubricating oil inside the reflux box 1201 is sucked by the oil pump 1203 and transported to the oil filter 1204 for filtration.

[0038] During use, the output shaft of the motor 8 is decelerated through the reducer 9, so that the output shaft of the reducer 9 drives the first gear 1102 to rotate, so that the first gear 1102 is meshed and transmitted to the chain 1101 for synchronous rotation, and the chain 1101 is meshed and transmitted to the second gear 1103 for synchronous rotation, so that the second gear 1103 drives one of the rotating shafts 6 to rotate, and drives one of the running wheels 5 to rotate.

The reliability is improved, the service life of the first gear 1102 and the second gear 1103 is extended, and the lubrication effect of the transmission gears of the peripheral transmission concentrator is improved.

[0041] During the circulation of the lubricating oil, when the lubricating oil is transported through the cooling metal pipe 1205, heat is conducted through the cooling metal pipe 1205. At this time, the heat of the cooling metal pipe 1205 is conducted to the heat dissipating fins 1206. At this time, the temperature of the heat dissipating fins 1206 increases, and the cooling fan 1207 rotates to transport the air at the lower side of the heat dissipating fan 1207 to the upper end, so that the air circulation disperses the heat of the heat dissipating fins 1206, and cools the heat dissipating fins 1206 and the cooling metal pipe 1205, and further cools the lubricating oil transported in the cooling metal pipe 1205, thereby reducing the occurrence of oxidation and deterioration of the lubricating oil due to temperature, and ensuring the lubricating effect of the lubricating oil.
