Suspension roller mill is mainly composed of main machine, analyzer, powder collector, fan, pipeline and other components. The qualified particle size materials in the silo are continuously fed into the main machine grinding room by the feeder for grinding. The ground powder is carried away by the air flow blown into the mill by the centrifugal fan, and is classified by the analyzer. The powder that meets the fineness enters the cyclone powder collector through the pipeline with the air flow for separation and collection. The finished powder is discharged through the discharge valve, and the separated air flow is sucked into the centrifugal fan by the return air duct at the upper end of the cyclone powder collector. The unqualified powder is separated by the analyzer and thrown to the cylinder wall, falls along the cylinder wall and returns to the mill for grinding.

[0003] The mechanical transmission of the main machine of the roller mill has gears, bearings and other parts, and these parts need to be lubricated and cooled with lubricating oil. For example, in the centralized lubrication system of the main machine of the roller mill with application number 201320247448.4, in order to lubricate the gears and bearings in the roller mill, a lubrication station needs to be set up, and a filtering mechanism and a cooling mechanism for filtering and cooling the lubricating oil respectively are set between the lubrication station and the roller mill. In the prior art, the filtering mechanism and the cooling mechanism are split, that is, the filtering is a unit and the cooling is a unit, which are independent of each other, thereby causing problems such as complex structure and high system cost.

Example

[0028] See also Figure 1 , 2 As shown, a centralized filter cooler includes a cylinder 1, a cover 2 fixedly covering the upper opening of the cylinder 1, a filter cylinder 3 fixedly embedded in the cover 2 and extending into the cylinder 1, and a cooling pipe 4 arranged in the cylinder 1.

[0029] See also Figure 3 As shown, the cylinder 1 is a cylinder structure with an open upper end, a sealed lower end, and a cylindrical inner cavity. In order to facilitate the detachable connection between the cylinder 1 and the cover 2, a connecting flange 11 is fixedly connected to the upper end surface of the cylinder 1. The connecting flange 11 can be integrally formed with the upper end of the cylinder 1, or welded to the outer circumference of the upper end of the cylinder 1. A plurality of connecting through holes 12 are provided on the connecting flange 11. The connecting bolts 13 are inserted into the cover 2 and the connecting through holes 12, and the cylinder 1 and the cover 2 are fixedly connected by connecting nuts 14. In order to improve the sealing between the connecting flange 11 and the cover 2, an O-ring 2 15 is embedded in the upper end surface of the connecting flange 11, and the upper end surface of the sealing ring 2 15 can be pressed against the lower end surface of the cover 2. An oil outlet pipe 16 connected to the inner cavity of the cylinder 1 is fixedly connected to the upper part of the cylinder 1 by welding.

[0030] See also Figure 6 As shown, the filter cartridge 3 includes a filter cartridge body 31 with an opening at the upper end and a sealed lower end, a limiting flange 32 integrally formed or welded at the upper end of the filter cartridge body 31, and a fixing plate 33 which is covered on the limiting flange 32 and detachably fixedly connected to the upper end surface of the cover body 2. The fixing plate 33 and the limiting flange 32 are split structures, so that it is convenient to clean the inside of the filter cartridge body 31. The limiting flange 32 extends from the outer circumference of the filter cartridge body 31 to its outside. A plurality of filter holes 34 are provided on the outer circumference and the lower end of the filter cartridge body 31, and the specific size of the filter hole 34 can be determined according to the lubricating oil and the impurities to be filtered.

[0031] See also Figure 5 As shown, the fixing plate 33 is a disc-shaped structure, on which a plurality of connecting through holes 331 are opened, and a cylindrical fixing plate boss 332 is integrally formed and fixedly provided on the lower end surface of the fixing plate 33, and the fixing plate boss 332 can be coaxially arranged with the fixing plate 33. The oil inlet pipe 333 is embedded and welded on the fixing plate 33 and the fixing plate boss 332, and the inner part of the oil inlet pipe 333 is connected to the inner cavity of the cylinder 1.

[0032] See also Figure 4 As shown, the cover body 2 is a disc-shaped structure matching the cylinder body 1 and the connecting flange 11. A second connecting through hole 21 corresponding to the first connecting through hole 12 is provided on the cover body 2, and the connecting bolt 13 can be inserted into the second connecting through hole 21. A water inlet pipe 22 and a water outlet pipe 23 that can communicate with the inner cavity of the cylinder body 1 are respectively embedded and welded at the upper end of the cover body 2.

[0033] In order to facilitate the placement of the filter cartridge body 31 in the inner cavity of the cylinder 1, a cover body through hole 24 is opened on the cover body 2, and a limiting groove 25 is opened on the upper end surface of the cover body 2 at the cover body through hole 24. The limiting groove 25 is a hollow cylindrical structure and its inner diameter is larger than the inner diameter of the cover body through hole 24. When the filter cartridge body 31 is inserted into the cover body through hole 24, the limiting flange 32 can be removably embedded in the limiting groove 25 and supported by the bottom of the limiting groove 25, thereby preventing the filter cartridge body 31 from falling into the inner cavity of the cylinder 1.

[0034] In order to prevent the filter cartridge body 31 from shaking, when the fixing plate 33 is fixedly connected to the cover body 2, the fixing plate boss 332 can be embedded in the limiting groove 25 above the limiting flange 32. At this time, the lower end surface of the fixing plate boss 332 is tightly pressed against the upper end surface of the limiting flange 32.

[0035] Furthermore, in order to improve the sealing between the fixing plate 33 and the cover body 2, a sealing ring 26 is embedded in the upper end surface of the cover plate 2 outside the limiting groove 25. When the fixing plate 33 is fixedly connected to the cover body 2, the upper end surface of the sealing ring 26 can be pressed against the lower end surface of the fixing plate 33.

[0036] In order to facilitate the quick connection and disassembly between the fixing plate 33 and the cover body 2, a plurality of connecting through holes 27 are opened on the upper end surface of the cover body 2. The connecting through holes 27 correspond to the connecting through holes 331 on the fixing plate 33. The fastening bolts 28 can be passed through the connecting through holes 331 and threadedly connected in the connecting through holes 274, so that the fixing plate 33 can be detachably fixedly connected to the cover body 2.

[0037] See also Figure 2 As shown, the water inlet end 41 of the cooling pipe 4 is fixedly connected to the water inlet pipe 22 through the existing pipe joint structure, and the inner cavities of the two are interconnected. The water outlet end 42 of the cooling pipe 4 is fixedly connected to the water outlet pipe 23 through the existing pipe joint structure, and the inner cavities of the two are interconnected. In order to further improve the cooling effect of the cooling medium in the cooling pipe 4 on the lubricating oil, the cooling pipe 4 is a spiral structure and is sleeved on the filter cartridge body 31.

[0038] The working process of the embodiment of the utility model is as follows:

[0039] Connect the water inlet end 41 of the cooling pipe 4 to the water inlet pipe 22, and connect the water outlet end 42 of the cooling pipe 4 to the water outlet pipe 23, then place the cooling pipe 4 in the inner cavity of the cylinder 1, and fix the cover 2 to the connecting flange 11 by connecting bolts 13 and connecting nuts 14;

[0040] Then, the filter cartridge body 31 is inserted into the cover body through hole 24 so that the filter cartridge body 31 enters the inner cavity of the cartridge body 1, the fixing plate boss 332 is embedded in the limiting groove 25, and the fixing plate 33 is fixedly installed on the cover body 2 by fastening bolts 28;

[0041] The water inlet pipe 22 and the water outlet pipe 23 are respectively connected to the cooling system, and the oil inlet pipe 333 and the oil outlet pipe 16 are respectively connected to the lubrication system. When the centralized filter cooler is working, the lubricating oil flowing out of the suspension roller mill enters the filter cylinder body 31 through the oil inlet pipe 16 for filtration, and overflows to the inner cavity of the cylinder 1 through the filter hole 34, and then flows out of the cylinder 1 through the oil outlet pipe 16 and enters the lubrication station; in the process of lubricating oil filtration, the cooling medium such as cooling water flows into the cooling pipe 4 from the water inlet pipe 22, and flows out of the cooling pipe 4 through the water outlet pipe 23, thereby cooling the lubricating oil in the cylinder 1.
