The up-flow pressure screen used for paper making comprises a screen cylinder and a rotor, wherein the screen cylinder and the rotor are installed in the up-flow pressure screen. The rotor comprises a rotor body and a wing piece which is installed on the rotor body. The wing piece is of a straight strip shape and arranged vertically, the wing piece is installed on the rotor body through a connection rod, and the wing piece comprises a top portion wing piece, a middle portion wing piece and a bottom portion wing piece. The top portion wing piece, the middle portion wing piece and the bottom portion wing piece are evenly distributed in a circumference mode along the rotor body. The bottom end of the top portion wing piece is flush with the top end of the middle portion wing piece, and the bottom end of the middle portion wing piece is flush with the top end of the bottom portion wing piece. The wing piece of the rotor is short in length, simple in machining and low in cost. In addition, the wing piece is light, so that in the process of rotating of the rotor, wasted energy is small.
Description
Technical field
The utility model relates to paper making equipment, especially a kind of up-flow pressurized screen for papermaking.
Background technology
Pressurized screen is to digest and assimilate a kind of novel regenerated paper pulp material screen optional equipment that import model machine technology is developed out.This equipment is the up-flow structure at the characteristics design of impurity in the paper pulp, can be widely used in the screening of the preceding slurry of scalping, fine screen and paper machine of various paper pulp slurrying, has good working performance and reliability.
Pressurized screen is taked the up-flow structural design that the bottom is advanced to starch, bottom row weighs slag, light slag is arranged at the top, has solved the problems referred to above effectively.Air in light impurity and the slurry is raised to the top slag-drip opening naturally and discharges, and heavy seeds one enters body can be deposited to the bottom discharge.Like this, shorten the time of staying of impurity in the sieve district on the one hand effectively, reduced the possibility of impurity circulation, improved screening effeciency; Prevent the damage that heavy seeds causes rotor and screen cylinder on the other hand, prolong the service life of equipment.
The shortcoming that existing up-flow pressurized screen exists is that rotor blades length is long, shape in the shape of a spiral, and weight is comparatively heavy, the production and processing difficulty, cost is increased, and in addition, consumes more energy in the time of the rotor rotation.
The utility model content
Problem to be solved in the utility model is to improve the problem that the up-flow pressure sieve rotor fin length that is used for papermaking in the background technology is long, complex-shaped, weight is comparatively heavy.
In order to overcome the above problems, the utility model provides a kind of up-flow pressurized screen for papermaking, comprise the screen cylinder, the rotor that are installed in the up-flow pressurized screen, described rotor comprises rotor body and is installed on fin on the rotor body, described fin is vertical bar shaped and vertically arranges, described fin is installed on the rotor body by connecting rod, described fin comprises that described top tab bottom is concordant with fin top, middle part along the circumferential equally distributed top tab of rotor body, middle part fin, bottom flaps, fin bottom, middle part is concordant with the bottom flaps top.
Described connecting rod is welded on the rotor body, and described fin removably is fixed on the connecting rod by screw, is provided with the pad of changeable between described fin and the connecting rod, regulates distance between fin and the rotor body by the thickness that increases or reduce pad.
Described fin top end face is the inclined-plane, and described inclined-plane reduces gradually along the fin rotation direction.
Described top tab, middle part fin, bottom flaps quantity are 6.
Up-flow pressurized screen for papermaking described in the utility model, comprise the screen cylinder that is installed in the up-flow pressurized screen, rotor, described rotor comprises rotor body and is installed on fin on the rotor body, described fin is vertical bar shaped and vertically arranges, described fin is installed on the rotor body by connecting rod, described fin comprises along the circumferential equally distributed top tab of rotor body, the middle part fin, bottom flaps, described top tab bottom is concordant with fin top, middle part, fin bottom, middle part is concordant with the bottom flaps top, the fin length of rotor of the present utility model is shorter, it is comparatively simple to add man-hour, cost is lower, fin is comparatively light in addition, makes that rotor is that the energy that consumes is less in rotation.

The specific embodiment
Below in conjunction with accompanying drawing a kind of up-flow pressurized screen for papermaking of the utility model is described further.
As shown in Fig. 1, Fig. 2, the up-flow pressurized screen that is used for papermaking of present embodiment, comprise the screen cylinder, the rotor that are installed in the up-flow pressurized screen, rotor comprises rotor body 1 and is installed on fin 2 on the rotor body 1, fin 2 is vertical bar shaped and vertically arranges, fin 2 is installed on the rotor body 1 by connecting rod 3, fin 2 comprises that top tab 21 bottoms are concordant with middle part fin 22 tops, fin 22 bottoms in middle part are concordant with bottom flaps 23 tops along rotor body 1 circumferential equally distributed top tab 21, middle part fin 22, bottom flaps 23.The fin length of rotor of the present utility model is shorter, and it is comparatively simple to add man-hour, and cost is lower, and fin is comparatively light in addition, makes that rotor is that the energy that consumes is less in rotation.
In the present embodiment, described connecting rod 3 is welded on the rotor body 1, fin 2 removably is fixed on the connecting rod 3 by screw 4, is provided with the pad 5 of changeable between fin 2 and the connecting rod 3, regulates distance between fin 2 and the rotor body 1 by the thickness that increases or reduce pad 5.Make that by this design distance can be regulated between fin 2 and the connecting rod 3, when fin 2 since service time long, cause its surface abrasion, distance between itself and the screen cylinder is increased, influence the active force of rotor, at this moment namely can increase the thickness of pad 5, can change thicker pad 5, also can be the quantity that increases pad 5, make that the distance between fin 2 and the rotor body 1 is bigger, namely the distance between fin 2 and the screen cylinder be littler.
As shown in Figure 3, in the present embodiment, described fin 2 top end faces are inclined-plane 6, and inclined-plane 6 reduces gradually along fin 2 rotation directions.This design makes fin 2 when rotated, and fin 2 top end faces have an impetus that makes progress to paper pulp, and the assist pressure sieve is realized the promotion to the up-flow of paper pulp.In addition, fin 2 top end faces can accelerate flowing of paper pulp to the stirring of paper pulp, help the mediation to screen cylinder, further prevent the obstruction of screen cylinder.In the present embodiment, described top tab 21, middle part fin 22, bottom flaps 23 quantity are 6.This quantity is the quantity that comparatively is fit to, can certainly be according to the size conversion of screen cylinder for still less or more.
The utility model is not limited to above embodiment and conversion.
