Mill belongs to the plant equipment of the slow-speed of revolution, heavy load, under the duty fluctuation of load very big, itself bears great impact equipment.To the horizontal pressure of roller generation radial effect, there is very big influence in the Mooney viscosity of sizing material, processing temperature, roll spacing and roller footpath to the size of horizontal pressure to sizing material between roll gap.The size of horizontal pressure influences the power consumption of mill and the working life of roller.Therefore, measure horizontal pressure, have practical significance instructing the design of mill selection of process parameters and equipment.In the laboratory, use foil gauge and measure mill roller horizontal pressure, position, the bonding method of foil gauge influence measurement result, and the error of measurement is big.The horizontal pressure measurement mechanism of mill roller in now also not being applied to produce.
Now with the safety pad as the mill safety guard; There is following shortcoming in this safety guard: 1, receive the influence of safety pad tablet quality bigger; Especially the uniformity of material therefor and mechanical strength is inhomogeneous, and the fluctuation range when damaging is bigger; 2, after the safe pad fragmentation, must shut down and change, maintenance load is big, loses time, and influences production efficiency; 3, safe pad has only defencive function, and not with control interconnection, can not carry out omnibearing protection to equipment.
The utility model content
The utility model will solve the horizontal pressure that also is not applied to the mill roller now and measure
Device and with the technical problem of safety pad as the existing shortcoming of mill safety guard, provides a kind of and can accurately measure, use reliable and have the horizontal pressure on-line measurement of mill roller and the safety guard of good safeguard protection kinetic energy.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of mill roller horizontal pressure on-line measurement and safety guard, and measurement, the safeguard protection element of measurement and safety guard are pressure sensors; This pressure sensor is fixedly mounted on the front end of the piston rod of roll-setting gear hydraulic cylinder, with the action roller tube bearing block contact matching that action roller tube bearing is installed; The control system connects pressure sensor and roll-setting gear.
The action roller tube is meant the roller that can move the adjustment roll spacing.Pressure sensor is fixedly mounted between action roller tube bearing block and the roll-setting gear, promptly is positioned at the position that safe pad is installed in existing mill.Pressure sensor substitutes safe pad, is fixedly connected on the front end of piston rod, contacts with action roller tube bearing block.During mill work, the roller horizontal pressure is delivered to pressure sensor through action roller tube bearing block, and pressure sensor is passed to the control system with institute's measuring pressure information, and the control system is according to the information Control roll-setting gear roll adjustment of input horizontal pressure.Pressure sensor and roll-setting gear are one, experience pressure sensitive, accurately, use reliably, solved the technical problem of mill roller horizontal pressure on-line measurement; When mill in case of emergency; Pressure sensor is passed to the control system with pressure signal; Control system control hydraulic distance-regulating device separates two rollers on the one hand; Pressure release is rapidly controlled system's main control system shutdown or counter-rotating back on the other hand and is shut down, and protection equipment preserves from. realize the mill safeguard protection.The maintenance time and the workload of mill reduce significantly, have improved production efficiency.
The pressure sensor that is fixedly mounted on the front end of piston rod is ceramic pressure resistance type pressure sensing
Device.
A kind of mill roller horizontal pressure on-line measurement and safety guard are measured and measurement, the safeguard protection element of safety guard are pressure sensors; This pressure sensor is fixedly mounted in the inflow pipeline of roll-setting gear hydraulic cylinder; The control system connects pressure sensor and roll-setting gear.
Roll-setting gear utilizes the input pressure of hydraulic cylinder to promote action roller tube bearing block, the action roller tube moves, the adjustment roll spacing.In mill when work,, pressure sensor is surveyed oil-feed oil pressure information with institute and is passed to the control system, and the control system is according to oil-feed oil pressure, the oil mass of the oil pressure information Control roll-setting gear hydraulic system of input, accurate roll adjustment.Pressure sensor has substituted the safe pad that existing mill is used as the parts of mill safety guard.Pressure sensor is directly experienced the oil-feed oil pressure of hydraulic cylinder, pressure sensor experience pressure sensitive, accurately, use reliably, solved the technical problem of mill roller horizontal pressure on-line measurement; When mill in case of emergency; Pressure sensor is passed to the control system with pressure signal; Control system control hydraulic distance-regulating device separates two rollers on the one hand; Pressure release is rapidly controlled system's main control system shutdown or counter-rotating back on the other hand and is shut down, and protection equipment preserves from. realize the mill safeguard protection.The maintenance time and the workload of mill reduce significantly, have improved production efficiency.
Pressure sensor is fixedly mounted in the inflow pipeline at hydraulic cylinder oil-in place.It is more accurate to measure horizontal pressure.
The pressure sensor that is fixedly mounted in the inflow pipeline is oil cylinder oil pressure sensor or hydraulic system oil pressure sensor or oil pump oil pressure sensor or oil pressure sensor.
The utility model has the advantages that: pressure sensor is fixedly mounted on the front end of roll-setting gear piston rod, with roll-setting gear be one, perhaps pressure sensor is fixedly mounted in the inflow pipeline of roll-setting gear hydraulic cylinder, directly experiences oil pressure.Pressure sensor has substituted the safe pad that existing mill is used as the parts of mill safety guard.Pressure sensor experience pressure sensitive, accurately, use reliably, solved the technical problem of mill roller horizontal pressure on-line measurement, overcome safe pad as the existing shortcoming of mill safety guard.The maintenance time and the workload of mill reduce significantly, have improved production efficiency.
