Abstract
A kind of pressafiner of the present invention, including feed inlet, discharge port, helical axis, filtrate plate, are additionally provided with that coaxial with helical axis and what is be axially movable unloads material rotor, with the axial thrust device for unloading material rotor direct connection；It unloads material rotor and also has independent gear.
Description
Technical field
The invention belongs to pulp and paper industry machinery fields, and in particular to a kind of pressafiner.
Background technique
The feed end of traditional pressafiner is communicated with the atmosphere, i.e., feed end does not have pressure.When feed end has pressure
When, it needs that header box is arranged, the feed end that just can enter pressafiner after eliminating by header box into slurry pressure just can guarantee
The normal work of pressafiner.Disadvantage is not easy to realize automatic control first is that complex procedures, second is that charging pressure head pair can not be utilized
Slurry is squeezed, and the energy is wasted.
Traditional has the pressafiner of pressure in discharge end, pressure pulp screen, continuous steaming such as with spiral slag-draining device
There is pressure in the discharge end of pressafiner in charging material plug spiral of saucepan (device) etc..This style of conventional crushers
Operating condition it is harsh, need operative employee's field monitor its work to prevent pressure from regurgitating.
Summary of the invention
The purpose of the present invention cannot utilize merely change using charging (slurry) pressure first is that solving prior art conventional crushers
The defect that extruding force away from spiral is dehydrated slurry；Second is that solving squeezer discharging end seal of the existing discharge end with pressure
It is stifled not will cause the problem of pressure is regurgitated and revealed sternly；Third is that stablizing discharge concentration.
A kind of technical solution of pressafiner described herein are as follows: a kind of squeezer, including feed inlet, discharge port,
Helical axis, filtrate plate, are additionally provided with that coaxial with helical axis and what is be axially movable unloads material rotor, with the axis for unloading material rotor direct connection
To thrust device；It unloads material rotor and also has independent gear.
The transmission switch of the axial position for unloading material rotor and independent gear realizes linkage.
The material rotor that unloads unloads the end face of the outer housing discharge end of material rotor and squeezer when being coupled with helical axis disengaging
Between be additionally provided with static seal device.
The present invention has the advantages that a kind of squeezer, including feed inlet, discharge port, helical axis, filtrate plate, it is additionally provided with
It is coaxial with helical axis and what is be axially movable unloads material rotor, with the axial thrust device for unloading material rotor direct connection；Unload material rotor also
With independent gear.Axially movable to unload material rotor and rotate together with helical axis, spiral pressure will be gone out by unloading material rotor
The material of crusher circumferentially screws out.
When unloading the axial distance between material rotor and pressafiner discharge end end face less than a certain numerical value, in order to prevent
It unloads material rotor continuous rotation discharging and destroys material degree of stoppering, system can indicate that independent gear stops operating by limit signal.
When unloading the axial distance between material rotor and pressafiner discharging end face is zero (contacting with each other), in order to prevent
Material passes through the slot leakage unloaded between material rotor and the squeezer outer housing discharge end end face of fixation not rotated, and unloads material rotor
Static seal setting is additionally provided between the outer housing discharge end end face of squeezer.
Detailed description of the invention
Fig. 1 is a kind of internal structure chart of squeezer；
Fig. 2 is a kind of internal structure chart of the discharge port part of squeezer；
Wherein appended drawing reference are as follows:
Feed inlet 1；Discharge port 2；Helical axis 3；Filtrate plate 4；Unload material rotor 5；Thrust pressurizing device 6；Independent gear 7；Pressure
The end face 8 of crusher outer housing discharge end；Unload material rotor material toggling tooth 10；Push system 11.
Specific embodiment
Embodiment 1
A kind of pressafiner described in the present embodiment is as shown in Figure 1 and Figure 2, including feed inlet 1, discharge port 2, helical axis 3,
Filtrate plate 4, is additionally provided with that coaxial with helical axis 3 and what is be axially movable unloads material rotor 5, with the axial direction for unloading 5 direct connection of material rotor
Thrust device 6；Material rotor 5 is unloaded also with independent gear 7.
Embodiment 2
The biography of the axial position for unloading material rotor 6 and independent gear 7 in a kind of pressafiner described in the present embodiment
Dynamic switch realizes linkage.When unloading the axial distance between material rotor and pressafiner discharge end end face less than a certain numerical value,
Material rotor continuous rotation discharging is unloaded in order to prevent and destroys material degree of stoppering, and system can indicate that independent gear stops by limit signal
Rotation stop is dynamic.
Embodiment 3
A kind of pressafiner described in the present embodiment unloads material rotor 5 when being coupled with the disengaging of helical axis 3, unloads material rotor 5
Static seal device is additionally provided between the end face 8 of the outer housing discharge end of squeezer.
