Abstract
The utility model relates to the improved technology of cement mechanical equipment, in particular to an oil supply system with synchronous roller lifting of a vertical mill, comprising an oil supply station and four grinding roller oil cylinders, wherein the four grinding roller oil cylinders are in two groups; two opposite grinding roller oil cylinders are in one group; and two oil supply pipes led from the oil supply station are respectively connected with the two groups of grinding roller oil cylinders. The oil supply system is characterized in that a one-way throttle valve is added at the connecting end of the nearer grinding roller oil cylinder in each oil supply pipe. The utility model solves the problem of asynchronous roller lifting of the existing vertical mill and the damaged grinding roller mechanical limit, and is mainly used for improving the oil supply system of the vertical cement mill.
Description
(1) technical field: the utility model relates to the improvement technology of cement machinery equipment, and especially a kind of Vertical Mill is lifted the roller oil supply system synchronously.
(2) background technology: Vertical Mill is one of capital equipment of cement raw material processing.In Vertical Mill, general design has four grinding rollers, is symmetrically distributed around mill, and the act roller action of four grinding rollers is to be carried out by four grinding roller oil cylinders.In the prior art, four grinding roller oil cylinders are divided into two groups, the grinding roller oil cylinder of positioned opposite is divided into one group in twos, and oil pump station is arranged on a side of Vertical Mill, like this in every group of grinding roller oil cylinder, must have one nearer apart from oil pump station, one is far away, nearer one of every group of grinding roller lifts roller earlier when causing that because of resistance of ducting difference four grinding rollers are lifted the roller action in practical operation, and far away one then lags behind and lifts roller.This situation can cause the grinding roller raised earlier to a high position be mechanical position limitation during to upper limit another grinding roller also not lift and put in place, and at this moment can not be with the oil pump station fuel cut-off, waiting for that a grinding roller far away lifts the grinding roller that has previously put in place in the process that puts in place and also have elevatory action to spacing the pressures reinforcing of vertical mill tool under the oil pressure effect, under serious situation, will cause the mechanical position limitation of the grinding roller that puts in place earlier destroyed.
(3) summary of the invention: the purpose of this utility model will solve in the existing Vertical Mill four grinding rollers exactly, and to lift rollers asynchronous, influence mechanical position limitation service life, to cause the ruined problem of mechanical position limitation of the grinding roller that puts in place earlier when serious, and provide a kind of Vertical Mill to lift the roller oil supply system synchronously.
Concrete scheme of the present utility model is: the oil supply system at existing Vertical Mill is improved, it includes oil pump station and four grinding roller oil cylinders, four grinding roller oil cylinders are divided into two groups, the grinding roller oil cylinder of positioned opposite is divided into one group in twos, draw two fuel feed pumps from oil pump station and connect two groups of grinding roller oil cylinders respectively, it is characterized in that: in every fuel feed pump, add one-way throttle valve with a nearer grinding roller oil cylinder link.
The utility model is owing to installed one-way throttle valve additional at two nearer grinding roller oil cylinder front ends, can regulate two nearer grinding roller oil cylinder fuel deliveries, make two grinding roller oil cylinder fuel supply flow rates nearer and far away in same group reach balance, thereby four grinding rollers are reached lift the effect that roller puts in place simultaneously simultaneously, avoided the pressure reinforcing spacing, the service life of having improved the Vertical Mill mechanical position limitation to the vertical mill tool.
(4) description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-oil pump station, 2, the 3-fuel feed pump, 4, the 5-one-way throttle valve, 6,7,8,9-grinding roller oil cylinder.
(5) specific embodiment:
Referring to accompanying drawing, the utility model includes oil pump station 1 and four grinding roller oil cylinders 6,7,8,9, four grinding roller oil cylinders are divided into two groups, to be divided into one group (be that grinding roller oil cylinder 6,8 is one group to the grinding roller oil cylinder of positioned opposite in twos, 7,9 for another stretches tight), draw two fuel feed pumps 2,3 from oil pump station 1 and connect two groups of grinding roller oil cylinders respectively, particularly: the link at fuel feed pump 2 and nearer grinding roller oil cylinder 6 adds one-way throttle valve 5; Promptly constitute the utility model and add one-way throttle valve 4 at the link of fuel feed pump 3 and nearer grinding roller oil cylinder 9.
