Abstract

The utility model discloses a flow-enlarging rotator of the pressurized screen, The utility model consists of a cylinder rotator body with a plurality of rotor plates. A plurality of pulp path holes are provided on the peripheral surface of the rotator body between the rotor plates, and the pulp path holes are connected to the rotator body. Interconnected pores are provided on the upper side surface and the lower side surface of the rotator body to connect with the internal cavity and the external cavity of the body. The internal cavity and the external cavity of the rotator are completely the same in this utility model, which actually increases the side space of the pressurized screen. As the pulp goes from outside to inside and is forced to pass the screen plate by the rotor pushing surface, a rapid supply of pulp can be made through the pulp path holes; as the pulp goes from inside to outside and is forced to pass the screen plate by the rotor pushing surface, a rapid flow through the pulp path holes is provided to the outlet of the syrup screen, thereby shortening the running path of the pulp. Being simple in structure, the utility model can effectively lower power consumption with high screening efficiency.

Description

The pressure sieve rotor of augmented flow

Technical field

The utility model relates to the papermaking equipment field, relates 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 in the utility model provides a kind of pressure sieve rotor that in time replenishes the augmented flow of slurries.

For achieving the above object, the technical solution of the utility model 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; The utility model rotor internal cavity 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 utility model 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 utility model is simple in structure, the pulp flow channel smoothness, and filter efficiency improves greatly.
