Outside, a turning bridge with a peripheral drive is attached to the frame, and on top of the frame, in the area of the flocculation chamber, there is a distribution chute with outlet connections installed 1

And: acquisition refers to water purification devices and can be used in sewage treatment of metallurgical, mining, coal mining and public utilities.

The purpose of the invention is to increase the efficiency of clarification of the node.

FIG. 1 shows a radial sump, general view; in fig. 2 section A-A in FIG. one; FIG. 3 is a sectional view of FIG. one; in fig. 4 - node I in FIG. 1; in fig. 5 — node II in FIG. one.

The radial sump consists of a body 1, a pipe 2 for supplying polluted water with inlets 3 and a rigid frame 4 to which a cylindrical overrun is attached. 5, forming a flocculation chamber in the center of the sump with walls of the central chamber 6, and with side walls of the sump peripheral upholding zone. The frame 4 is installed on the body of the central chamber 6 by means of vertical 7 and horizontal 8 rollers located along the perimeter of the central chamber 6. Vertika. the rollers 7 (rotate in the vertical plane) serve as clamps (supports) of the frame 4 in the vertical plane and ensure its Friction in the horizontal plane. The horizontal rollers 8 (rotate in the horizontal plane) serve as fixers for the frame 4 of the cylindrical partition 5 in the horizontal plane and ensure its fixed position; en1; e in the horizontal plane.

Flax 9, open at the top of the distribution chute 9 with outlets - MPS 10, placed -1-1 in its lower part. A rotary bridge 11 is attached to the frame 4 of the cylindrical partition 5 from the outside, so that it is uniform with it. rigid in the horizontal plane design, driven in rotation by a peripheral drive 12. Scraping devices (trusses) 13. Directly to the rotary bridge 11, scraper devices (trusses) 13. The blades 14 with an inclination to the central chamber 6, and the lower parts of the frame 4 - scrapping scrapers 15, and the casing of the central chamber 6 has annular partitions 16 which are inclined to the central chamber 6,.

In the casing of the central chamber 6 pumps 17 are located to remove sediment (sludge). The transfer chamber 6 is in communication with the settling zone by nozzles 18.

For the outer walls of the housing 1 is located catchment tray 19.

Radial sump works as follows.

The polluted water through the pipe 2 of the inlet and the inlet 3 enters the distribution, the elimination 1 of the chute 9, and then through the outlet nozzles 10 into the flocculation chamber formed by the cylindrical

the partition 5 and the wall of the central chamber 6. The upper part of the distribution chamber is open. Sidewall 9 allows the contaminated will to enter the chute iiocToHHHo, and those located in the lower

frame 4 of the cylindrical partition 5 evenly direct contaminated water with sludge into the flocculation chamber on the blades 14. When contaminated water hits the blades 14, the primary separation of large particles of suspended substances occurs and, due to the inclination of the blades, they move to the annular partitions 16.

The blades 14 are mounted on the frame 4 around its perimeter with a gap to each other, due to which smaller particles fall into the lower part of the flocculation chamber, directly into the sediment suction zone.

The number of rows of blades, their angle of inclination and the number of blades in a row can be different and is determined depending on the degree of contamination of water, its quantity and other factors.

The annular partitions 16 are installed along the perimeter of the central chamber 6, attached to it, being separated from each other at a certain distance. The blades 14 are located above the bulkheads 16 at their lower edge and continuously direct the sludge into them. Large particles of sludge directed to annular partitions 16 are compacted in them and sent to the suction zone. Smaller particles of sludge with water from the lower part of the flocculation chamber fall into the sedimentation zone of the housing 1, fall into the sediment, and the clarified water is removed through the catchment tray 19.

The rotary bridge 11 uses the peripheral drive 12 to drive the scraper device (trusses) 13 and the frame 4 of the cylindrical partition 5 with raking scrapers 15, which during their movement move the sediment to the slurry pipe 18, from where it is removed by pumps 17 placed inside The number of pivot bridges 11 with scraping devices 13 can be different: if their two or more torque values transmitted to the casing of the central chamber are sharply reduced.

The movement of the frame 4 of the cylindrical partition 5 is carried out by means of vertical rollers 7 and horizontal rollers 8 installed along the perimeter on the wall of the central chamber 6. Vertical rollers 7 serve

supporting frame 4 and ensure its rotation in the horizontal plane, and horizontal rollers 8 exclude the possibility of displacement of the frame in the horizontal plane relative to the axis of rotation, i.e. axes of the central chamber 6.

By using the proposed device, the efficiency of water clarification is increased as a result of the even and intensive separation and displacement of the largest ones; particles of suspended matter to the wall of the central chamber and sufficiently fast removal of sediment from the flocculation chamber; the dispersion of particles in water in the peripheral zone decreases, which leads to a decrease in the sediment layer and a decrease in the dynamic loads on the scraper devices (trusses), drive bridges, the central chamber and the wall of the settler, as a result of which the material consumption of the scavenging and displacing structures and the settler elements decreases and central chamber; in addition, the reliability of operation is increased as a result of installation of the frame of a cylindrical partition on the casing of the central chamber and its rotation on the vertical and horizontal rollers together with the drive axle.

Thus, the proposed septic tank allows for the effective clarification of wastewater, is reliable in operation and is economical.
