Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] like figure 1 As shown, the coal mill gearbox lubrication cooling cleaning system used in the coal mill gearbox lubrication cooling cleaning method includes:
[0028] Coal mill gear box 1, oil pump 2, two-speed motor 3, heater 4, double-chamber filter 5, cooler 6 and controller (not shown in the figure), oil pump 2 is driven by two-speed motor 3. The dual-chamber filter 5 has a filter cartridge 51 and a filter cartridge 52, one of which can be used as a backup.
[0029] In order to lubricate, cool and clean coal mill gears and bearings by using the coal mill gearbox lubrication, cooling an...

The invention discloses a coal mill gear case lubricating and cooling washing method. The coal mill gear case lubricating and cooling washing method comprises the steps that a coal mill gear case, an oil pump, a heater, a double-chamber filter and a cooler are connected in sequence through a pipeline, a lubricating and cooling washing loop is formed, a two-speed motor is connected with the oil pump, a thermal resistor is arranged inside the coal mill gear case, and the thermal resistor, the two-speed motor, the heater and the cooler are remotely connected with a controller; the controller is started, and receives sensing signals of the thermal resistor, displays an oil temperature value inside the gear case on a display interface of the controller and controls work of the two-speed motor, the heater and the cooler according to the oil temperature value. A lubricating and cooling washing system does not have a self-carrying oil tank, the coal mill gear case is used as the oil tank, and therefore system is small in occupied space and investment. By controlling the two-speed motor through the controller, lubricating oil heating waiting time in the process of starting a coal mill can be reduced notably, and protection of every component of the coal mill is strengthened.
Description
technical field [0001] The invention relates to the field of coal mills, in particular to a method for lubricating, cooling and cleaning a gear box of a coal mill. Background technique [0002] Coal mill is a machine that breaks coal and grinds it into coal powder. It is an important auxiliary equipment for pulverizing systems in industries such as electric power, metallurgy, building materials, and chemicals. During the pulverized coal grinding process of the coal mill, the gears and bearings in the reducer, a key component, need to be well lubricated, cooled and cleaned. However, the current coal mill lubrication system either requires a high-level oil tank or a separate lubricating oil tank, resulting in greater construction difficulty, investment costs, and insecurity. At the same time, it takes up a lot of space, and the entire pipeline heating, filtering, and cooling link structure It is unreasonable and imperfect; and the degree of automation is not high, and the pro...
