Abstract
The utility model discloses an oil inlet pipeline structure. An oil inlet pipeline is connected to a coal mill speed reducer from an oil pump; and the oil inlet pipeline is provided with a filter. The oil inlet pipeline structure has the advantage of preventing impurities from entering the coal mill speed reducer along with lubricating cooling oil, and plays a role in protecting the coal mill speed reducer.
Description
Technical field
The utility model belongs to the coal pulverizer technical field, relates in particular to the in-line structure of coal pulverizer lubricating and cooling system.
Background technique
Coal pulverizer is with coal crusher and wears into the machinery of coal dust that it is the important supplementary equipment of pulverized coal furnace.Coal pulverizer is in running, and its speed reducer can generate heat and easy abrasion, normally moves for guaranteeing coal pulverizer, is necessary to the speed reducer cooling and is lubricated.The in-line structure of present coal pulverizer lubricating and cooling system is to the speed reducer fuel feeding through a transport pipe.But the quality of lubricating cooling oil alternates betwwen good and bad, and can have a large amount of impurity in the ropy lubricating cooling oil, and these impurity cause the damage of coal pulverizer speed reducer easily along with lubricating cooling oil gets into the coal pulverizer speed reducer.
The model utility content
The utility model technical problem to be solved provides a kind of in the in-line structure of avoiding impurity to get into the coal-grinding speed reducer along with lubricating cooling oil, to overcome the deficiency that existing technology exists.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of in-line structure, said in-line is connected to the coal pulverizer speed reducer from oil pump, it is characterized in that: said in-line is provided with filter.
For avoiding filtering effect, said filter has two, parallel with one another being located on the in-line.
For the monitoring filter stops up, also be provided with the differential pressure switch that is connected in parallel on the filter on the said in-line.
For avoiding lubricating cooling oil to reflux, said filter is provided with safety check in the outlet port.
Adopt technique scheme, can filter lubricating cooling oil in the in-line, filter out the impurity in the oil, thereby avoid impurity, play the effect of protection coal pulverizer speed reducer along with lubricating cooling oil gets into the coal-grinding speed reducer through increasing filter.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and embodiment the utility model:
Fig. 1 is the coal pulverizer lubricating and cooling system structural drawing of the utility model;
Among the figure:
The 100-filter, 102-oil pump, 200-coal pulverizer speed reducer, 300-in-line, 400-differential pressure switch, 500-safety check.
Embodiment
As shown in Figure 1, the in-line structure of the utility model is that wherein in-line 300 is connected to coal pulverizer speed reducer 200 from oil pump 102 to the improvement of existing in-line 300.Improvements are for being provided with two filters parallel with one another 100 on in-line 300.
And,, also be provided with the differential pressure switch 400 that is connected in parallel on the filter 100 on the in-line 300 for the monitoring filter stops up.In case filter 100 stops up, filter 100 two ends must have great pressure reduction, and at this moment, differential pressure switch 400 will be reported to the police.In addition, reflux for avoiding lubricating cooling oil, filter 100 is provided with safety check 500 in the outlet port.
More than be exactly the in-line structure of the utility model, this in-line structure has avoids impurity along with the advantage that lubricating cooling oil gets into the coal-grinding speed reducer, plays the effect of protection coal pulverizer speed reducer.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
