Description

Technical Field

[0001] This utility model belongs to the field of speed reducer cooling technology, specifically relating to an oil circuit system for a classifier speed reducer. Background Technology

[0002] Steel slag plants typically have multiple mill production lines, each equipped with an air classifier. The reducer is one of the core components of the air classifier. During operation, a failure in any air classifier reducer can cause the entire mill production line to shut down, with a long processing time and significant economic losses due to downtime. Currently, the reducer's oil circuit design is unreasonable, resulting in poor heat dissipation and consistently high oil temperatures, which can easily lead to accelerated wear and damage to the internal gears of the reducer. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide an oil circuit system for a classifier reducer.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An oil circuit system for a classifier reducer includes an oil delivery pipe, a transition oil tank, an oil pump, an oil filter, a cooler, a cooling oil tank, a monitoring module, an early warning module, and a control system.

[0006] Lubricating oil is filled into the gearbox. The bottom outlet of the gearbox side wall is connected to the transition oil tank through an oil supply pipe. The oil pump is installed on the transition oil tank, and the bottom of the lubricating oil in the transition oil tank is connected to the inlet of the oil pump through an oil supply pipe. The outlet of the oil pump is connected to the inlet of the oil filter. The outlet of the oil filter is connected to the inlet at the bottom of the side wall of the cooling oil tank. The top outlet of the cooling oil tank is connected to the inlet at the top of the gearbox through an oil supply pipe. The cooler is installed on the other side of the cooling oil tank.

[0007] The monitoring module includes a temperature sensor and a pressure gauge. The temperature sensor is installed at the outlet of the cooling oil tank, and the pressure gauge is installed on the oil supply pipe between the cooling oil tank and the gearbox.

[0008] The control system is electrically connected to the oil pump, oil filter, cooler, temperature sensor, pressure gauge and early warning module respectively.

[0009] Furthermore, the cooler is either a water cooler or an air cooler.

[0010] Furthermore, the early warning module can use any type of audible and visual alarm.

[0011] Furthermore, the oil supply pipe between the reducer box and the transition oil tank is provided with an upwardly protruding inverted U-shaped pipe structure.

[0012] Furthermore, the height of the inverted U-shaped tube is 2 / 3 of the height of the lubricating oil level in the gearbox.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model adds a lubricating oil circulation system to the existing reducer box. The circulation system is equipped with an oil filter to filter the oil, prevent impurities from entering the oil circuit and reduce the risk of blockage. At the same time, the oil is cooled by a cooler to reduce the oil temperature and improve the lubrication effect.

[0015] 2. This utility model is equipped with a monitoring module and an early warning module to monitor the oil circuit operation status in real time.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, an oil circuit system for a classifier reducer includes an oil delivery pipe 3, a transition oil tank 4, an oil pump 5, an oil filter 6, a cooler 7, a cooling oil tank 8, a monitoring module, an early warning module, and a control system.

[0020] Lubricating oil 2 is filled into the gearbox 1. The bottom outlet of the side wall of the gearbox 1 is connected to the transition oil tank 4 through the oil supply pipe 3. The oil supply pipe 3 between the two is provided with an upward-protruding inverted U-shaped pipe structure. The height of the inverted U-shaped pipe is 2 / 3 of the height of the lubricating oil level in the gearbox 1, ensuring that about 20-30% of the oil volume is retained in the transition oil tank 4 when the machine is stopped, preventing the pump from running dry. The oil pump 5 is installed on the transition oil tank 4, and the bottom of the lubricating oil in the transition oil tank 4 is connected to the inlet of the oil pump 5 through the oil supply pipe 3. The outlet of the oil pump 5 is connected to the inlet of the oil filter 6. The outlet of the oil filter 6 is connected to the inlet at the bottom of the side wall of the cooling oil tank 8. The top outlet of the cooling oil tank 8 is connected to the top inlet of the gearbox 1 through the oil supply pipe 3. The cooler 7 is a water cooler, which is installed on the other side of the cooling oil tank 8.

[0021] The monitoring module includes a temperature sensor 9 and a pressure gauge 10. The temperature sensor 9 is located at the outlet of the cooling oil tank 8, and the pressure gauge 10 is located on the oil supply pipe 3 between the cooling oil tank 8 and the reducer box 1.

[0022] The control system is electrically connected to the oil pump 5, oil filter 6, cooler 7, temperature sensor 9, pressure gauge 10 and early warning module respectively. The early warning module adopts an audible and visual alarm.

[0023] The cooler 7 can also be an air cooler.

[0024] The early warning module can also use any other type of audible and visual alarm.

[0025] The working process of this utility model:

[0026] When this utility model is not started, the reducer box 1 and the transition oil tank 4 are connected by the oil supply pipe 3 to form a communicating vessel, and the height of the inverted U-shaped pipe is lower than the height of the liquid level, so that some of the lubricating oil 2 enters the transition oil tank 4 through the oil supply pipe 3 until the level of the lubricating oil 2 in the reducer box 1 is the same as the height of the inverted U-shaped pipe.

[0027] In operation, the cooler 7 is activated by the control system to cool the cooling oil tank 8. The oil pump 5 is also activated, and the lubricating oil 2 in the transition oil tank 4 enters the cooling oil tank 8 after being filtered by the oil filter 6 under the action of the oil pump 5. Under the action of the oil pump 5, the lubricating oil 2 continuously enters the cooling oil tank 8, and the lubricating oil 2 slowly increases from bottom to top in the cooling oil tank 8. At the same time, the cooler 7 cools the lubricating oil 2. When the lubricating oil 2 reaches the outlet of the cooling oil tank 8, the temperature sensor 9 detects the temperature of the lubricating oil 2 in real time and transmits it to the control system. The control system dynamically adjusts the water flow rate of the cooler 7 according to the data of the temperature sensor 9. The cooled lubricating oil 2 returns to the reducer box 1 along the oil delivery pipe 3 to form a circulation. The pressure gauge 10 detects the oil pressure in real time and transmits the data to the control system.

[0028] When the temperature or oil pressure of the lubricating oil 2 exceeds the preset warning value, the warning system will issue an alarm to remind the operator to check. When the oil temperature is >60℃, the cooler 7 will start the high-speed cooling mode.

[0029] When the temperature or oil pressure of lubricating oil 2 exceeds the preset limit, the oil circuit system will directly shut down through the control system to prevent accidents from occurring.
