SU1234370A1 - Radial settling tank with device for removing oil from water surface - Google Patents

Description

2. Otst.oynik pop. 1, which is due to the fact that the radial partitions are made of floating material, installed between the supply tube and the wall of the settling chamber. They can be rotated around a horizontal axis.

3 .. The sump of claim 1, of tl and - h. The fact that the floating tray is installed on the farm, and its end relates to the purification of industrial wastewater, namely, devices for removing oil of other floating contaminants from the surface of the water, and can be used, for example, in radial sumps for recycling water from rolling mills of metallurgical an enterprise.

The purpose of the invention is to increase the efficiency of oil removal.

FIG. 1 shows the sump, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section. - G in FIG. 2 ..

The settling tank contains a central supply pipe 1, a flocculation chamber 2 located inside the settling chamber 3, which is surrounded by a collection chamber 4 for melting impurities. A truss 5 is fixed on the central tube for rotation, on which a floating scraper 6 fixed at an angle to the truss and a chute 7 are fixed. A recessed tank 8 is also attached to the truss with an oil pump 9. The reservoir is connected by a flexible pipe 10 to a tray 7, and a pump-pressure pipeline 11 with an oil sump 12, having a gravity flow pipe 13. It has flooded partitions | 4 rotatably around a horizontal axis in the settling chamber 3 to form

tsov part of the densely irilstp to frf.ni-, ke of the settling chamber.

4. The sump of claim 1, from l and the fact that the oil sump is made in the form of an annular tray mounted concentrically around it. the supply pipe, and the outlet of the pipeline for pumping oil is located above the oil sump.

 sections. The clarified water is discharged from the settling tank through holes 15 into tray 16. Float tray 7 is installed on the truss, and its end is fitted tightly to the wall of the settling chamber. Tray 7 is connected to the primer 17.. . .

The device works as follows. ,

Grush water from the central tube 1 enters the flocculation chamber 2. From the flocculation chamber, the polluted water passes into the settling chamber 3, where the largest amount of

oils. With the help of a rotating truss 5 in the settling basin, an floating scraper 6 is moved at an angle to the radius. Meeting with a partitioned flooded partition 14, the scraper

 squeezes the oil into the floating impurities collection chamber 4, in which the oil is captured by the floating tray 7 and supplied to the wet 17. From example 17 to the flexible outlet 10, the oil is pumped out by the neosome 9 through the pipeline 11 into the oil sump 12. The pipeline 11 rotates with the farm, its outlet moves in a circle above the stationary annular

an oil collector 12, which is located above the settling tank around the central pipe 1. From the oil collector 12, the oil is removed through a gravity flow line 13. Purified water is drained from

the sump through the holes 15 in the channel 16.
