Abstract
The present invention discloses a pressure sieve rotor capable of increasing flow rate. It includes a cylindrical pressure sieve rotor self-body, on the pressure sieve rotor self-body several rotor blades are fixedly mounted, on the peripheral surface of the rotor self-body between the described rotor blades several pulp-passing holes which are communicated with internal cavity of rotor self-body are set, and the upper end surface and lower end surface of the described rotor self-body are equipped with the through holes which are respectively communicated with internal cavity and external cavity of said rotor self-body, and the internal cavity and external cavity of said rotor are completely identical. Besides, said invention also provides the working principle of said pressure sieve rotor and its operation method.
Description
Technical field
The present invention relates to the papermaking equipment field, relate in particular to a kind of rotor of pressurized screen.
Background technology
Pulp screen is one of requisite visual plant in the Waste Paper Handling process, and screening can be removed plurality of impurities such as lumps, sicker, hot-melt object, chip etc., and the quality quality of final products depends on the height of screening effeciency to a great extent.As shown in Figure 5, the cylindrical rotor of usual pressure sieve is the cylindric of sealing, screen cylinder 3 is divided into A, B two parts with the working space of pulp screen simultaneously, paper pulp or flow to B through screen cylinder from A, perhaps flow to A from B through screen cylinder, in this course of work, the effect of the rotor 2 on the rotor body 1 is pushing away slurry or inhaling slurry by rotor, paper pulp impurity is pushed away or inhale, prevent that paper pulp impurity from stopping up screen cloth from the screen cylinder surface.But its shortcoming is: between rotor and the screen cylinder to deposit the slurry space less, the paper pulp in this space can not flow away or be replenished very soon, greatly reduces the screening effeciency of pulp screen, has also increased simultaneously the energy consumption of equipment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pressure sieve rotor that in time replenishes the augmented flow of slurries.
For achieving the above object, technical scheme of the present invention is: the pressure sieve rotor of augmented flow, comprise columnar pressure sieve rotor body, be installed with some rotary blades on the pressure sieve rotor body, the circumferential surface of the rotor body between the described rotary blade is provided with some slurry holes excessively that communicate with the rotor body inner chamber, and the upper and lower end face of described rotor body is provided with the intercommunicating pore that is communicated with rotor body inner chamber and exocoel.
As a kind of improvement, the described slurry hole of crossing has to the paper pulp direction of motion.
As a kind of improvement, described slurry hole excessively is slotted hole or circular hole.
Owing to adopt technique scheme, the pressure sieve rotor of augmented flow, comprise columnar pressure sieve rotor body, be installed with some rotary blades on the pressure sieve rotor body, the circumferential surface of the rotor body between the described rotary blade is provided with some slurry holes excessively that communicate with the rotor body inner chamber, and the upper and lower end face of described rotor body is provided with the intercommunicating pore that is communicated with rotor body inner chamber and exocoel; Rotor internal cavity of the present invention is fully identical with the rotor exocoel, is actually the space that has increased the pressure sieve rotor side, when slurry flows from outside to inside, when slurry is pushed away the pressure of slurry face by sieve plate by rotor, can replenish slurry rapidly by crossing the slurry hole; When slurry from inside to outside flowed, slurry is inhaled the slurry face by rotor to be forced by sieve plate, starches the grout outlet that the hole can flow to pulp screen rapidly by crossing, and has shortened the walking path of paper pulp; The present invention is simple in structure, can effectively reduce power consumption, and screening effeciency is higher.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 4, the pressure sieve rotor of augmented flow, comprise columnar pressure sieve rotor body 1, be installed with some rotary blades 2 on the pressure sieve rotor body 1, the circumferential surface of the rotor body 1 between the described rotary blade 2 is provided with some slurry holes 21 excessively that communicate with the rotor body inner chamber, and the upper and lower end face of described rotor body 1 is provided with the intercommunicating pore 22 that is communicated with rotor body 1 inner chamber and exocoel.
As shown in Figure 3, pass through for ease of slurries, the described slurry hole 21 of crossing has to the paper pulp direction of motion, and the resistance that passes in and out slurry like this can reduce, and further saves the energy.
Described slurry hole 21 excessively is a slotted hole.Certainly, as the common engineers and technicians in present technique field, described mistake is starched the version that circular hole also can be adopted in hole 21.
The present invention is simple in structure, the pulp flow channel smoothness, and filter efficiency improves greatly.
