Abstract
The invention discloses a discharge device of a stay tower with middle and high concentration, which comprises a discharge hole which is arranged at the bottom of the stay tower, a screw discharge device is vertically arranged on a discharge hole, the arrangement of the screw discharge hole leads the speed of discharging to be easy to control, and slurry in the stay tower is smoothly discharged out since the continuously stirring and rotating of the screw discharge device pushes the slurry to discharge, meanwhile, since the pressure and drag force of the screw discharge device is small, powerconsumption is greatly reduced, energy resource is saved, maintenance cost is reduced, and life span of the invention is increased.
Description
Technical field
The present invention relates to a kind of papermaking equipment, relate in particular to the drawing mechanism of using on a kind of paper pulp middle and high concentration reserving tower.
Background technology
At present, the structure at used reserving tower discharging opening 1 place as shown in Figure 3, be provided with high dense discharger at reserving tower discharging opening 1 place, high dense discharger normally is made up of 2～3 rake arms 6 and some spirals, rake arm 6 is pressed under the paper pulp of whole reserving tower, slowly the rake arm 6 of rotation is pushed the high consistency pulp of reserving tower bottom to blanking port 7, because the concentration height of paper pulp, suffered pressure and the resistance of rake arm 6 is all very big, if it is thick inadequately that rake arm 6 roots are made, bending strength is just big inadequately, is easy to become curved, has reduced the service life of high dense discharger, increased the cost of maintenance, and the power consumption height, simultaneously because the rotating speed of rake arm 6 must be very slow, make the speed of plasma discharge material also be difficult to control.
Summary of the invention
It is little that technical problem to be solved by this invention provides a kind of power consumption, and can make the drawing mechanism of middle and high concentration reserving tower of the smooth discharge of middle and high concentration slurry.
For solving the problems of the technologies described above, technical scheme of the present invention is: the drawing mechanism of middle and high concentration reserving tower, comprise the discharging opening that is arranged on the reserving tower bottom, and described discharging opening place is vertically installed with spiral discharge device.
As a kind of improvement, described spiral discharge device comprises motor, the gearbox that is connected with described motor power, and the discharging spiral of fixedlying connected with the clutch end of described gearbox, the free end of described discharging spiral is deep in the described reserving tower.
As further improvement, the tower wall at described discharging opening place or close described discharging opening place is provided with lubricated water adding apparatus.
As further improvement, described lubricated water adding apparatus comprises lubricated water water inlet, is communicated with described lubricated water water inlet and around some inlet openings of described tower wall setting.
Owing to adopted technique scheme, the drawing mechanism of middle and high concentration reserving tower comprises the discharging opening that is arranged on the reserving tower bottom, and described discharging opening place is vertically installed with spiral discharge device; The setting of spiral discharge device, make the speed of discharging be convenient to control, because the continuous rotation of spiral discharge device, promote the discharge of slurry, the slurry that stops in reserving tower is discharged smoothly, suffered pressure and the resistance of spiral discharge device is little simultaneously, the power consumption of Jian Shaoing greatly, save the energy, reduced maintenance cost, increased service life of the present invention.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the partial enlarged drawing at I place among Fig. 1;
Fig. 3 is the prior art structural representation.
The specific embodiment
Shown in Fig. 1 and Fig. 2 were common, the drawing mechanism of middle and high concentration reserving tower comprised the discharging opening 1 that is arranged on the reserving tower bottom, and described discharging opening 1 place is vertically installed with spiral discharge device 2.Described spiral discharge device 2 comprises motor 4, the gearbox 5 that is connected with described motor 4 power, the discharging spiral 21 of fixedlying connected with the clutch end of described gearbox 5, the free end of described discharging spiral 21 is deep in the described reserving tower, the slurry that the rotation of described discharging spiral 21 promotes in the reserving tower is discharged, and the velocity of rotation that can regulate described discharging spiral 21 by gearbox 5 as required, change the speed that slurry is discharged, and suffered pressure and the resistance of described discharging spiral 21 is little, and power consumption is reduced greatly.
The tower wall at described discharging opening 1 place is provided with lubricated water adding apparatus 3, and described lubricated water adding apparatus 3 also can be arranged near on the tower wall at described discharging opening 1 place certainly.
Described lubricated water adding apparatus 3 comprises lubricated water water inlet 31, is communicated with described lubricated water water inlet 31 and around some inlet openings 32 of described tower wall setting.Described inlet opening 32 is distributed on the circumferential wall of reserving tower.Because described inlet opening 32 is little, so the water that enters in the reserving tower is fewer, a spot of water level is between the housing of slurry and reserving tower, significantly reduced the frictional resistance of slurry with housing, play lubricated effect, help the smooth discharge of middle and high concentration slurry, make power consumption low, simultaneously minimum to the reduction of pulp concentration again, do not influence operation to the back prologue.
The present invention is adapted to the discharge after middle and high concentration slurry stops especially, and power consumption is low, and discharge velocity is convenient to control.
