SU31753A1 - Sectional trap for collecting fiber from wastewater of paper machines - Google Patents

Description

The author's certificate No. 25393 describes a trap for collecting fiber from wastewater of paper-making machines, divided by additional bulkheads into a number of cells, forming a cylinder inside which the trap is. the rum is placed in a pipe provided with two rings with holes that coincide when it rotates with the openings of the inner cylindrical wall of each cell and opens in the upper end of the interior of its supporting pipe and in the lower channel into the channel formed by the outer surface of the pipe and the wall of the cells for further direction the fibers which settled in cells in the corresponding receiver. Regardless of the single and two light arrangement of the cells for settling the fiber, a rotating ring is applied on the central tube, which is enclosed by a fixed ring with a series of openings connected by tubes with cells.

In the proposed sectional coupling, an annular chute is placed at the outlet of the wastewater supply pipe, divided by partitions into sections and equipped with pipes ending with regulating valves of the settling basins with

(103)

clarified water automatic movement.

In FIG. 1 is a top view of the trap; FIG. 2 is a side view.

 The proposed trap (Figs. 1 and 2) consists of a series of symmetrically installed sumps 14 of conical, prismatic or other shape, on top of which an annular chute 30 is located, divided by partitions 5 / into separate sections according to the number of sumps. From each section there is a branch pipe or pipe 4 coming to the sump, the end of which is located opposite the geometric axis of the bonus.

Outflow water enters the trough through pipe 3, which is driven into a circular motion from the drive. In the septic tanks there is a drain valve regulating the time of the clot of the clot, valve 15 and a mechanism for removing clarified water. The latter consists of a lever 7 with a weight 10 mounted on one end, and the other articulated with a rod 6, the lower end of which is connected to a crane 12 on the discharge pipe 77. The rod 6 in its upper part is equipped with a bucket 5 with an opening 9 in its bottom clarified water runoff.

When the sump is filled, the tap 12 is closed, as the clot leaks, the water level drops, the lever 7 deviates from its position and the tap 12 opens, resulting in clarified water in the pipe 11 flowing into the chute / 7. At this time, the pipe 5 approaches the section and fills the bed 14 through the bucket 5, and the excess water is poured over its edges. Under the influence of the weight of water in the bucket, the rod 6 is lowered, the valve 12 is closed, the load 10 is lifted, and the sump 14 is filled with water. The filling and emptying of the settling tanks alternate in time, depending on the flow rate of the clot through the valve, / 5n the corresponding speed of movement of the pipe 3.

Modification of the spout. (It is worth it that, instead of the spill mechanism, conical sumps are placed in the sumps down pipe 29 for iriem brightened water, which displaces the already clarified water upwards into the concentrically located along the sump side of the sump pocket 28, and from it sewage system 27.

The subject matter of the invention.

1. A sectional trap for collecting fiber from wastewater of papermaking machines, characterized in that the supplying wastewater, which is set in a circular motion from a suitable drive, has an annular chute 30, divided by partitions 31, into sections equipped with nozzles or pipes 4, terminated at the top, provided at the lower ends with taps 15 of the settling tanks 14, which regulate the descent of the clot, with an automatically operating mechanism consisting of a two-arm lever placed at each to remove clarified water 7 with a weight 70 mounted on one end and articulated on the other with a rod 6, movably connected at the lower end with a tap / 2 drain pipe //, and at the upper end equipped with a bucket 3 with an opening 9 in the bottom of it for draining brightened water ( Fig. 1 n 2).

2. Modification of the mechanism for removal of clarified water mentioned in paragraph I, characterized in that in the settling basins J4 along their central axes are placed conical sockets downward of a pipe 29 for receiving clarified water, displacing the clarified water already upwards, after removing the clot from the bottom, in a concentric positioned pockets at the upper sides of the settling basins 28 and from the latter into the sewer 27 (Fig. 2). in “Avieimu author's certificate of N.
