Abstract
The utility model discloses an internal water spraying device for a raw material mill, which comprises a water pump house, the raw material mill, a grinding roller, a water inlet pipe and a water spraying pipe, wherein the grinding roller is arranged in the raw material mill, the water spraying pipe is connected with the water pump house through the water inlet pipe, the water inlet pipe is arranged outside the raw material mill, and the water spraying pipe extends from the outside of the raw material mill into the grinding roller part arranged inside the raw material mill. After the technical scheme is adopted, the water inlet pipe is arranged outside the raw material mill, the water spraying pipe extends from the outside of the raw material mill into the grinding roller arranged inside the raw material mill, the original condition that the water spraying is outwards expanded in the internal center of the raw material mill is changed, the inward fixed-point water spraying from the outside is realized, the flushing abrasion of materials on the water inlet pipe and the water spraying pipe in the powder grinding process is reduced, the service life of the device is prolonged, the condition of instability of the material layer caused by material accumulation because of water seepage is reduced, simultaneously, the space for protecting lubricating oil pipes of the grinding roller is enlarged, and the condition of oil pipe damage caused by the mutual friction between the lubricating oil pipes is reduced.
Description
Technical field
The utility model relates to the raw mill that is used for manufacture of cement, waterworks in particularly a kind of raw mill.
Background technology
Waterworks plays in raw mill is used and stablizes bed of material vital role in the raw mill, directly affects the stability of production, with effective service condition of other associate members, and the convenience of maintenance maintenance etc.As shown in Figure 1; water plant 1 is that raw mill 3 supplies water by water inlet pipe 2; water inlet pipe 2 extend into raw mill 3 central interior; connect three water jet standpipes 4 herein and be respectively three grinding rollers, 5 water sprays; the waterworks of this structure causes material erosive wear to water inlet pipe 2 and water jet standpipe 4 in grinding process more serious; and the solid accumulation that causes because of infiltration is more; the bed of material that causes can't stabilizing influence production; be an impediment to the space of protection grinding roller 5 lubricating pipes simultaneously; in the course of time, the phase mutual friction between lubricating pipe and the lubricating pipe that causes damages.
The utility model content
The utility model provides a kind of long service life, stablizes waterworks in the good raw mill of bed of material effect in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: waterworks in the raw mill, comprise grinding roller, water inlet pipe and water jet standpipe in water plant, raw mill, the raw mill, water jet standpipe is connected with water plant by water inlet pipe, described water inlet pipe is located at the raw mill outside, and water jet standpipe is extend into the grinding roller place of raw mill inside by the raw mill outside.
Adopt technique scheme; water inlet pipe is located at the raw mill outside; water jet standpipe is extend into the grinding roller place of raw mill inside by the raw mill outside; change original in raw mill the center expand outwardly the situation of water spray; ecto-entad fixed point water spray; reduce material erosive wear to water inlet pipe and water jet standpipe in grinding process; extender work-ing life; the bed of material that the solid accumulation that minimizing causes because of infiltration causes can't be stable situation; increase the space of protection grinding roller lubricating pipe simultaneously, reduce the phase mutual friction between lubricating pipe and situation that the oil pipe that causes damages.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, waterworks in the raw mill of the present utility model, comprise grinding roller 5, water inlet pipe 2 and water jet standpipe 4 in water plant 1, raw mill 3, the raw mill 3, water jet standpipe 4 is connected with water plant 1 by water inlet pipe 2, water inlet pipe 2 is located at raw mill 3 outsides, and water jet standpipe 4 is extend into grinding roller 5 places of raw mill 3 inside by raw mill 3 outsides.This embodiment has three water jet standpipes 4 and evenly arranges along raw mill 3 circumference, and water inlet pipe 2 also correspondingly is provided with two and is connected with three water jet standpipes 4 respectively, and the water-in of two water inlet pipes 2 is connected with water plant 1 by a house steward 8.
Three water jet standpipe 4 ecto-entads fixed point water sprays; reduce material erosive wear to water inlet pipe and water jet standpipe in grinding process; extender work-ing life; the bed of material that the solid accumulation that minimizing causes because of infiltration causes can't be stable situation; increase the space of protection grinding roller 5 lubricating pipes simultaneously, reduce the phase mutual friction between lubricating pipe and situation that the oil pipe that causes damages.
