Description

SP

The invention relates to devices for the separation of solid and liquid media and can be used for the purification of natural and waste waters in the chemical, metallurgical, mining and other industries of the national economy.

The purpose of the invention is to simplify the design and expand the technological possibilities.

Fig, 1 shows a sump round; shape; FIG. 2 is a section A-A in FIG. 1; FIG. 3 shows a rectangular shaped sump; fig 4 is a view B of fig 3

The thin lagoon contains a body 1, thin lamellas in the form of blocks 2, consisting of tubular elements 3 with open channels and tubular elements 4, executed closed at the top and bottom, to impart floatability to block 2, Blocks 2 are interconnected and the tray 5 of floating matter discharge by means of hooks 6, the sump contains a scraper farm 7 for collecting sediment and floating substances, supported by means of channels 8 on the casing, mechanism 9 for turning the truss, pipe 10 for supplying purified water, tray 11 for discharging clarified water, pipe 12 for withdrawal draft and partition 13,

The sump works as follows,

The water to be purified flows through pipe 10, flows under the partition 13, comes to the surface through elements 3, and then is discharged through tray 11 to the limits of the structure. The farm 7, resting with its surface part on the housing 1 through the channels 8, makes by means of the mechanism 9, swinging rods at an angle of rotation up to 360 around the tray 5 of the removal of floating substances. (At the same time, the vertical truss elements of the truss pass smoothly between the rollers 2, the sediment is driven by the scraper truss to the building axis and is drained through the pipe 12, and the floating substances - along the tray 5,

The retention of thin-layer modules in water is ensured as follows. The modules located under tray 5 emerge due to the presence of closed elements 4 in them and thus are fixed below the water level (fixing the modules to tray 5 can be ensured in any way without

chi close the channels, which is not important). All subsequent modules, placed in concentric circles with a gap (for moving vertical rod elements), are fixed by means of hooks 6 of the previous module, which compensate for the force or moment of forces due to the presence of floating closed channels on one side of this module and lean it with its own hooks (hook) located on the side opposite to the closed elements, in this case the subsequent module, and t, d.

To reduce the number of closed channels, while ensuring the reduced self-consolidating effect of the blocks in the device, they can be made longer than open channels.

The proposed device is simpler in construction and less material-intensive than the known ones. The fastening elements of the thin-layer module are manufactured by assembling the latter in factory conditions, which provides a significant simplification and acceleration of the installation of the sump. During operation, clogging of thin layers is possible. The design of the settling tank makes it easy, for example from a raft, to dismantle a thin-layer module and clean its blocks. The big advantage of the proposed facility is that its thin-layer module can be mounted on any area, with any shape of the body and in combination with various devices for collecting sediment, clarified water, etc.

Formula 1 of the invention, a thin-layer settling tank, containing a housing, thin-layer blocks installed in it in the form of tubular ones. elements with hooks, devices for supplying purified water and removal of clarified water, sediment and floating substances, characterized in that, in order to simplify the design and expand technological capabilities, some tubular elements are made closed at the top and bottom to give floatability to the unit , while the blocks are interconnected and with devices for removing floating substances by means of hooks located on the side opposite to the closing of the elements.
