Abstract
A disclosed slag-water separation rotary screen comprises a filtering assembly and an overflow assembly; the filtering assembly is a screen drum driven by a transmission mechanism, and the screen drum is horizontally supported by a rotary mechanism disposed at a rack; one end of the screen drum is closed and the other end is open as a slag outlet; the slag discharging direction of a slag-discharging helical groove is from the closed end of the screen drum to the slag outlet; the overflow assembly comprises a fixed slag-water drum coaxially disposed in the screen drum; the slag-water drum is equally provided with slag-water outlets; and a slag-water inlet pipe entering into the screen drum via the slag outlet is communicated with the slag-water drum. By employing a structure of the static slag-water drum in the center and the circumferential rotating screen drum, water flows out from meshes of the screen mesh, and the slag are discharged through the slag outlet of the screen drum; and the water content of the slag is low because of long stay time of the slag in the screen drum, and thus blowdown flow rate is reduced and environment is protected better.
Description
(1) technical field:
The present invention relates to filter plant, be specially a kind of for the pulp water separation roto-siofter in chip water-scrubbing process.
(2) background technology:
Existing traditional pulp water separation equipment adopts the modes such as inclined-plane filtration to be separated pulp water, this kind equipment is also commonly called as slag-water separator, its effect is dam bulky grain solid impurity in water and drift, and compression dehydration, Chang Zuowei fine fack, the heap that it is extensively suitable for conveying that city and trade effluent rubbish incidental retain and pumping plant grid dirt stays and carries, and also can be used for the separation press dewatering of second pond scum silica frost, also can support the use with crush type grid.
Use in the chip water-scrubbing process of chemical industry, such slag-water separator Problems existing is: filtration time is short, and the water content of slag is large, and blowdown phenomenon is serious, is unfavorable for environmental protection.
(3) summary of the invention:
For this reason, the pulp water that the present invention proposes a kind of applicable chip water-scrubbing process is separated roto-siofter.
The technical scheme that pulp water of the present invention is separated roto-siofter comprises filter assemblies and overflow assemblies, described filter assemblies is the screen drum driven by transmission mechanism, described screen drum is by the slew gear horizontal support be located in frame, described screen drum one end close and the other end open wide become slag notch, uniform deslagging helicla flute on the circumference screen cloth inwall of screen drum, described deslagging spiral fluted deslagging direction from the blind end of screen drum to slag notch; Described overflow assemblies comprises the fixing pulp water cylinder with being located in screen drum, and uniform pulp water outlet on described pulp water cylinder, the pulp water input pipe being entered screen drum by slag notch is communicated with pulp water cylinder.
In the present invention, pulp water enters pulp water cylinder from pulp water input pipe, and pulp water is evenly derived between pulp water cylinder and screen cloth by pulp water cylinder; In the rotary course of screen drum, water flows out from the mesh of screen cloth, and slag charge is pushed slag notch to by deslagging helicla flute and discharged.
For obtaining better drainage effect, described pulp water cylinder is arranged near the blind end of screen drum, to increase slag charge in the time of staying of screen drum.
For the benefit of draining, described frame is located on gutter.
A kind of structure of described transmission mechanism comprises the Chain conveyer pair of at least one-level decreasing transmission and motor-driven reductor, the active minor sprocket of described Chain conveyer pair coaxially connects the output shaft of reductor, the driven hinge wheel of Chain conveyer pair and the blind end of screen drum are coaxially connected, and described active minor sprocket is connected by chain with driven hinge wheel.
A kind of structure of described slew gear comprises support roller, and described support roller is supported in the both sides bottom screen drum respectively at blind end and slag notch.
The screen drum diameter of different size is between φ 600mm ~ φ 1800mm, and length is between 2000mm ~ 8000mm, and the mesh diameter of screen cloth is between φ 1.5mm ~ φ 3.5mm.
Advantage of the present invention:
Pulp water of the present invention is separated the screen drum structure that roto-siofter adopts middle motionless pulp water cylinder and circumference to rotate, and water flows out from the mesh of screen cloth, and slag charge is discharged from the slag notch of screen drum; the time of staying of slag charge in screen drum is long; the water content of slag is low, reduces blowdown flow rate, better protects environment.
(4) accompanying drawing illustrates:
