Abstract

The utility model relates to a separating apparatus for paper making sewage, which belongs to the field of paper technology. The separating apparatus is designed for separating liquid sewage from solid sewage. The separating apparatus comprises a flow channel for liquid and solid combined sewage, a separating device for liquid substances and solid substances, and specially for fibrous substances, a delivery channel for liquid substances, and a collecting and delivery device for solid substances. The utility model is characterized in that the separating device for liquid substances and solid substances is a conical filter screen with a large upper end and a small lower end; the collecting and delivery device for solid substances is composed of a clean water spraying pipe for spraying water to the filter screen and a descent pipe which is led out from the lower end of the filter screen. The utility model is also suitable for other liquid-solid separation occasions, particularly suitable for separating white water in the process of paper making.

Description

The papermaking wastewater separating device

The utility model belongs to pulp technology for making paper, particularly relates to a kind of liquid state in the papermaking wastewater and solid-state especially fibrous matter being carried out isolating equipment.

The paper industry water consumption is big, and the sewage that pulping process is discharged is the dense chemical solution that contains more chemical substance, also contains especially fiber of solid matter simultaneously.Be the protection environment, this sewage should directly not discharge, and preferably it is carried out cyclicity and uses.For reaching the purpose that recycles, at first sewage is carried out liquid, solid-state separation, in order to avoid fiber amasss into obstruction on stream with regard to needing.For this reason, in the past electrostatic precipitations or bubble floating methods of adopting all need make sewage flow slowly for a long time even leave standstill more, need the large-area pond of big volume; In recent years again on the basis of bubble floating method in addition felt hair roller to the adhewsive action of fiber, allow current on former basis, to quicken to some extent, but still tool comparatively large vol, and above-mentioned each method is all insufficient to the separating effect of sewage and fiber, is being difficult to take into account aspect floor space, hour flow and the separating effect three.

The purpose of this utility model provide a kind of occupation of land less, the papermaking wastewater separating device of hour flow height, liquid state and fibrous matter good separating effect.

The purpose of this utility model is achieved in that

A kind of papermaking wastewater separating device, include the tripping device of runner, liquid state and the solid-state especially fibrous matter of liquid-solid mixed sewage, the delivery channel of fluent meterial, the collection and the take-off equipment of solid matter, it is characterized in that: the tripping device of described liquid state and solid matter is a up big and down small conical screen; The collection of described solid matter and take-off equipment are to the clear water shower of filter screen spray and the decline pipeline of drawing from the filter screen bottom.

The fiber on the filter screen is in time collected and exported to the utility model owing to spray to filter screen with clear water, keeps filter screen that liquid is had bigger spillage, thereby can realize bigger hour flow; By selecting the big filter screen of mesh number on the unit surface, the separating effect that can obtain for use; Because filtration process does not need liquid-solid mixed sewage layering, the unhurried current in the time of need not growing does not need big long-pending fluid capacitance device or pond, so can reduce floor space greatly again.

Introduce an embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is that master of the present utility model looks synoptic diagram.

Fig. 2 is a schematic top plan view of the present utility model.

As depicted in figs. 1 and 2: liquid-solid mixed sewage flows into the ring groove 2 with current stabilization dividing plate 21 from managing 1, be full of of periphery equably to conical screen 3 in the overflow of ring groove 2 backs from its internal ring wall 22, based on the solid matter of fiber by filter screen 3 detentions, liquid sewage is flowed out by pipe 4 then from filter screen 3 seepages.

Clear water is from managing 5 inputs, flow into horizontal, be the shower 6 of axis rotation with the medullary ray of conical screen, clear water sprays to the wire side of filter screen 3, impulsion is by the fibrous matter of filter screen 3 detentions, it is compiled to the center of filter screen 3 downwards along the domatic of conical screen, discharge from fiber downtake 7.

Wherein shower 6 is except being horizontally disposed with as shown in Figure 1, also can be obliquely installed by the conical surface that is parallel to filter screen 3, or pick up high its on this basis slightly and lean on end of center of turning circle, do not hindering under the prerequisite that fibrous matter compiles downwards, shower 6 is tried one's best near the wire side of filter screen 3, to improve the utilization ratio of its head.

For making things convenient for the liquid among the cavity A to discharge, then make the position of pipe connecting 4 become the lower-most point of cavity A, shown in two dot chain line among Fig. 1 from managing 4.

The utility model also can be used for other liquid-solid separation occasion, is particularly useful in the paper-making process separation to " plain boiled water ".

With Fig. 1 as Figure of abstract.
