Abstract
The utility model relates to a stirring device of a thickener of chemical engineering and mining machinery, belongs to the improvement of a bottom stirring device of a thickener, and particularly relates to a bottom stirring device of a thickener, which comprises the thickener, wherein the conical bottom of the slurry pool of the thickener is provided with a discharge opening; a support fixedly connected at the upper part of the conical bottom shell of the slurry pool is provided with a hydraulic motor; the output shaft of the hydraulic motor is connected with a stirring shaft through a coupler; the stirring shaft is provided with a combined stirrer with a helicallobe and a paddle blade; and the lower end of the stirring shaft is arranged on the bottom support through a bearing. The bottomstirring device not only has short stirring shaft, good driving stability and long equipment service life, but also can control the base flow concentration of the slurry pool of the thickener, prevent the slurry from precipitating, and lead the discharging of the discharge opening to be smooth.
Description
Technical field
The utility model relates to a kind of chemical industry, mining machinery concentrator agitating device, belongs to the bottom agitating device of the improvement, particularly a kind of concentrator of concentrator bottom agitating device.
Background technology
In actual production, there is following problem in 50 meters peripheral transmission Hhigh-efficient thickeners:
1, central stirring shaft is long, reaches 13 meters, poor stability, and easily swing causes the reducer gear engagement bad, and reducer gear and casing repeatedly damage;
2, bulky grain solid material ratio big (about diameter 30mm) accounts for 30%, and easily heavy ore deposit causes discharge hole for discharge not smooth, and causes the regular obstruction of underflow pump, causes very big puzzlement to steady production.
Summary of the invention
The purpose of this utility model is to provide a kind of bottom agitating device of concentrator, and not only its shaft is short, and transmission stability is good, and service life of equipment is long, and can control concentrator stock tank underflow density, prevents the slip precipitation, makes discharge hole for discharge unobstructed.
The purpose of this utility model is achieved in that a kind of bottom agitating device of concentrator, comprise concentrator, conical lower section at the concentrator stock tank is being provided with discharge gate, on the affixed support in the top of the conical drain pan of stock tank, hydraulic motor is installed, hydraulic motor output shaft is connecting shaft by shaft coupling, combined impeller with helical blade and blade sheet is installed on shaft, and the lower end of shaft is installed on the bottom bracket by bearing.
Drive part of the present utility model: adopt the low rotation speed large torque hydraulic motor, utilize motor seal to be implemented in the slip and drive, solved the easily problem of swing of axial length; Motor drives by hydraulic power unit input hydraulic oil, and hydraulic pump adopts variable pump, can be according to the speed governing of industrial and mineral condition, to reach optimum Working; By pressure transmitter and network interface signal is delivered to Central Control Room in addition, realize realtime monitoring.
Slip in the concentrator stock tank is big because of solid particle size, sinking speed is fast, if can not satisfy the requirement that underflow is discharged by the paddle stirring at low speed, underflow density is uncontrollable and easily stifled, for cutting down the consumption of energy as far as possible, can reach the purpose of mixing discharging again, so adopt combined impeller with helical blade and blade sheet, do not stay the dead angle for making the cone edge, adopt blade type at the dead angle height, play a minor role by local shear forces, thereby reach the effect of smooth discharging.
What the utility model was different with traditional end stirring is the installation site, and the utility model is put into conical bottom with agitator, has solved a traditional end stirring bottom sealing difficult problem.
Therefore not only shaft is short for the utility model, and transmission stability is good, and service life of equipment is long, and can control concentrator stock tank underflow density, prevents the slip precipitation, makes discharge hole for discharge unobstructed.
