Description

Technical Field

[0001] The utility model relates to the technical field of lubrication and cooling, in particular to a lubrication and cooling device for a reducer. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] In the high temperature environment of the clinker kiln production plant, the cooling of the transmission parts is particularly critical. This is because high temperature will not only lead to a decline in equipment performance, but may also accelerate equipment wear, shorten service life, and even cause failure and shutdown. At present, the cooling of the reducer lubricating oil generally adopts a built-in serpentine cooling device, which is directly installed inside the reducer. However, this built-in serpentine cooling device has obvious shortcomings in practical applications. On the one hand, due to the limitations of its design and installation position, the cooling efficiency is relatively low, and it is often difficult to meet the high requirements of the reducer for cooling effect in a high temperature environment. On the other hand, once the cooling device fails, it is extremely inconvenient to handle. Since it is installed inside the reducer, maintenance personnel must shut down the machine before they can perform maintenance, replacement, and other operations, which not only seriously affects the production and operation of the clinker kiln, but also greatly increases production costs and downtime losses.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings, wherein:

[0011] Figure 1 A schematic structural diagram of a lubrication and cooling device for a reducer according to an embodiment is shown. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] Figure 1 FIG. 1 shows a schematic structural diagram of a lubrication and cooling device for a reducer according to an embodiment. Figure 1 As shown, the lubrication and cooling device for the reducer includes: a lubricating oil cooling channel located inside the reducer 1, a lubricating oil inlet and a lubricating oil outlet connected to the lubricating oil cooling channel, a filter 2, an oil pump 3, a shell and tube cooler 4, and a circulating cooling water pump ( Figure 1 not shown).

[0014] The lubricating oil enters the lubricating oil cooling channel inside the reducer 1 from the lubricating oil inlet, lubricates, cools, rust-proofs, cleans, buffers, etc. the bearings, gears, etc. inside the reducer 1, and takes away the heat, impurities, etc. inside the reducer 1, and then is discharged from the lubricating oil outlet and enters the filter 2.

[0015] The filter 2 is connected to the lubricating oil outlet and is used to filter impurities in the lubricating oil, keep the lubricating oil clean, and extend the service life. At the same time, the large-area filter can dissipate part of the heat in the high-temperature lubricating oil.

[0016] The oil pump 3 provides power for the lubrication cooling device. One end of the oil pump is connected to the filter 2 and the other end is connected to the shell-and-tube cooler 4. The oil pump 3 is used to provide power to suck out the lubricating oil filtered by the filter 2 and send it to the heat transfer pipe in the shell-and-tube cooler 4.

[0017] One end of the shell-and-tube cooler 4 is connected to the oil pump 3, and the other end is connected to the lubricating oil inlet, and is used to cool the lubricating oil from the oil pump 3 and then send it to the lubricating oil inlet. The shell-and-tube cooler 4 includes a heat pipe, a circulating cooling water inlet, and a circulating cooling water outlet. The heat pipe is used to receive the lubricating oil from the oil pump 3, and the heat pipe is surrounded by circulating cooling water. The circulating cooling water exchanges heat with the high-temperature lubricating oil in the heat pipe. The circulating cooling water absorbs heat and flows out of the shell-and-tube cooler 4. The high-temperature lubricating oil releases heat and cools down before flowing out of the shell-and-tube cooler 4, and enters the reducer 1 again through the lubricating oil inlet, and continues to take away the heat, impurities, etc. inside the reducer 1. In one embodiment, the heat pipe is a heat-conducting copper pipe.

[0018] The circulating cooling water pump is connected to the circulating cooling water inlet and the circulating cooling water outlet of the shell and tube cooler 4, and is used to provide power to make the circulating cooling water circulate in the shell and tube cooler 4. In one embodiment, the circulating cooling water inlet is located at the lower part of the shell and tube cooler, and the circulating cooling water outlet is located at the upper part of the shell and tube cooler.

[0019] In one embodiment, an oil pump with a rated flow rate of 100L / min and a rated pressure of 2.5Mpa is used to provide power for the lubrication and cooling device, so that the lubricating oil circulates in the system. A lubricating oil filter can be provided according to the delivery capacity of the oil pump to filter impurities in the lubricating oil, keep the lubricating oil clean, and extend the service life. At the same time, the large-area filter can dissipate part of the heat in the lubricating oil; the cooling of the system adopts a shell-and-tube cooler, which has a large heat exchange area and small space usage, and quickly exchanges the heat of the lubricating oil and is taken away by the circulating cooling water.
