Description

The device relates to water supply, for the treatment of water and can be used to treat surface wastewater from water sources.

A device for cleaning water and surface wastewater (A.S. No. 2040944, class B01D 21/24) A sump containing a rectangular tank, on the bottom of which there is a hydraulic system for removing sludge in the form of parallel pipes with nozzles connected through a collector to a pipe rinse water supply, inlet and outlet pipelines for the treated water and a pipe for draining the wash water with sediment. The sump is equipped with vertical partitions mounted on the bottom with the formation of longitudinal channels, and flaps pivotally mounted on the upper edge of the partitions with the possibility of rotation in the vertical plane, and the pipes are placed at the bottom of the channels.

However, the use of the known device does not allow to obtain the necessary level of cleaning due to clogging of the supply pipes with nozzles with sediment falling into the channels, jamming of the valves installed with the possibility of rotation in the vertical plane when filling the channels with sediment.

The closest technical solution for the totality of the signs and the achieved result is a device for treating water and surface wastewater (A.S. No. 1353463. Class. B01D 21/24). A sump including a housing with a device for supplying treated water and a water intake in the form of a vertical wall made with vertical parallel rows of holes, the horizontal axes of which are located at different levels with equal pitch in height, the second and underlying holes in height are equipped with valves connected by levers

with floats, and installed with the possibility of series-parallel overlapping of the holes.

The disadvantage of the known device in the complexity of the design due to the large presence of valves and levers with floats, which in the process can clog when there is a large amount of impurities in the wastewater.

The main objective of the utility model is to increase the efficiency of water treatment by providing a constant layer of surface water intake regardless of changes in the water level in the sump.

To achieve this goal, a sump, including a housing with a device for supplying treated water and water intake in the form of a fixed vertical wall, the device is additionally equipped with a movable vertical wall connected through rods with floats, and a fixed vertical wall is equipped with guides.

In relation to the prototype, the proposed device has the following distinctive features: the device is additionally equipped with a movable vertical wall connected through drafts with floats, and a fixed vertical wall is provided with guides.

The guides prevent the vertical movable wall from shifting to the horizontal plane. Floats connected through rods to a movable wall provide a constant surface layer of water intake.

The essence of the device is illustrated by graphic materials, which depict:

Figure 1 presents a General view; In Fig. 2, view A in Fig. 1.

The sump includes a housing 1, with a device 2 for supplying the treated water, a fixed wall 3 with guides 4, a movable wall 5 connected through rods 6 with floats 7, regulating the height of the drain, the suction pipe 8.

The sump works as follows:

Process water saturated with suspended particles enters the housing 1, into the bottom layers of the sump, through the supply device 2. When the process water flows, suspended particles are deposited in the intake, consisting of a fixed wall 3 and a movable wall 4, which block access to the polluted stream for getting to the suction pipe 8. When a large amount of water arrives, the water level in the sump increases and begins to exceed the height of the fixed wall 3, while the floats 7 connected to s 6, are raised and moved over a movable wall 5, which in turn shuts off the flow of contaminated. Vertical guides 4 prevent the displacement of the movable wall under the influence of horizontal flow velocity. When the flow rate of the water entering the sump decreases, the level begins to decrease, while the floats 7 lower and the movable wall 5 relative to the fixed wall 3 are lowered through the rods 6. The purified water of the surface layer of the clarified stream overflows between the floats 7 and the movable wall 5, and flows to the suction pipe 8 and is removed from the sump 1.

The technical result of the claimed device is to provide a constant layer of surface water intake regardless of changes in the water level in the sump.
