Sump - Accumulator

The utility model relates to apparatus for the treatment of storm and sewage from suspended solids and can be used in industry, as well as in the construction of treatment facilities at car repair plants, gas stations, parking lots and garages and other objects.

A device for thickening and clarifying suspensions is known, comprising a reservoir, means for introducing a suspension, mounted in the upper part of the reservoir, vertical hollow tubular filters mounted on the manifold partially immersed in the suspension and connected to the manifold, means for creating a direct and reverse flow of liquid or air, wherein the collector comprises a plate in which tubular filters are hermetically mounted and a removable tubular cover with one or more nozzles connected to the means for creating collector of direct and reverse flow of liquid and air, and hermetically covering the plate. RF patent No. 2072883, IPC B01D 27/08, 1997 ..

Known devices for clarifying liquids, which are sand traps and containing a direct channel with flow input and output devices located at the ends and with an inclined bottom, in the most inclined part of which there is a gutter for collecting several and a device for its removal, a circulation bubbler pipe is installed above the gutter to create a circulation flow in the cross section of the channel, while to the side wall of the channel adjacent to the least deep part of the bottom and the end wall in which the device for twater flow trays attached interconnected, bubble circulation pipe is connected to bubble tubes with their number increasing with distance from the downcomer and the transverse bubble tube installed between the input device and the end of the tray, attached to the side wall of the sand trap. Sand traps can be equipped with a dividing wall and a system of dividing rods installed along the channel at a certain angle

to the axis of the channel. In addition, the sand traps can be equipped with turbulizing plates attached to the side wall with their increasing length in the direction of the flow outlet, and on the side wall there are mounted rotary plates and rotary elements installed at an angle to the vertical, while the rotary elements are made in the form of rotary elbows with inlet and outlet openings. RF patent No. 2069718, IPC 6 E03F 5/14, 1996.

Known devices do not provide the required quality of cleaning, are difficult to manufacture, require significant capital costs associated with the installation of additional storage (receiving) containers.

The objective of the proposed utility model is to improve the quality of cleaning while simplifying the device, reducing capital costs.

This object is achieved in that the inventive device comprises a reservoir equipped with nozzles for introducing cleaned wastewater and drainage of clarified liquids located in the upper part of the tank, while a water divider is placed on the path of introducing the cleaned wastewater, and a perforated pipe is placed in the lower part of the reservoir for communicated with the means for its removal, and a pump for pumping clarified liquid, communicated with the outlet pipe, and between the perforated pipeline For pumping clarified liquids placed bounding partition. The watering and limiting partition is made fixed and flat.

Means for removing sludge can be made in the form of an external pump in communication with a perforated pipe by means of a transport pipe.

The sludge pipe may be further provided with monitoring means, for example a sludge level sensor.

The tank of the accumulator-sump has a streamlined shape and is made of an insulating material, for example, a polymer material.

vertically mounted pipe in communication with an external pump. A watering and restricting partitions are used as separating partitions, while a watering partition is installed in the path of the treated effluents, and prevents the formation of a turbulent fluid flow, as well as for uniform distribution of sediment in the lower part of the tank, and the restrictive partition is placed between the sediment pipe and the pump for pumping clarified liquid and serves to localize the formed sediment in the area of perforated pipeline. The length of the dividing walls, as a rule, is about 1/3 of the transverse diameter of the tank.

A comparative analysis of the proposed device with the prototype allows us to conclude that the criterion of "Novelty.

The design of the device is illustrated in the drawing.

Figure 1 shows a General view of the sump - battery.

The inventive device comprises a tank 1, located inside the tank 1, the inlet of the sewage to be cleaned 2, a water baffle 3, installed opposite the pipe 2, a perforated pipe for the formed sludge 4, located in the lower part of the tank 1, means for removing sludge, which is an external pump (on not shown), connected by means of a transport pipe 5 to a perforated pipe 4, delimiting a partition 6 placed between the perforated pipe 4 and the submersible pump m for evacuating clarified liquid 7, the output pipe for clarified liquid 8.

The device operates as follows.

During volley discharge of rain or industrial effluents, the processed fluid flows through the pipe 2 into the tank 1. The incoming fluid stream breaks up into the water separation wall 3 and fills the working volume of the tank 1 in the laminar flow mode. Under the influence of gravitational forces, the illumined substances are deposited on the bottom of the tank 1. Zone precipitation is limited by septum b.

After the estimated time or according to the testimony of the sludge level control sensor, turn on the submersible pump 7 and the clarified liquid from the reservoir 1 is pumped out through the outlet pipe 8. The working cycle is repeated again.

The precipitate formed is removed from reservoir 1 as it accumulates. When you turn on the external pump, the sediment through the perforation in the pipe 4 is sucked from the bottom of the tank 1 and through the transport pipe 5 is removed from the sump accumulator.

The inventive device can be manufactured in an industrial environment using standard equipment.

Using the inventive device allows to solve the problem, i.e. improve cleaning quality while flashing the device. Using the proposed device allows you to effectively clean up wastewater and storm water, and providing the ability to completely remove the liquid after the process of purification, reduces the capital cost of building and installing additional receiving tanks. With the correct calculation of the working volume of the claimed sump, there is no need for the construction and installation of receiving tanks. In addition, during non-working periods, the purified water does not remain in the tank, which prevents its souring and rotting of the installation. The inventive sludge removal unit allows you to expand the technological capabilities of the sump by providing the ability to work effectively as an underground sewage treatment plant without additional channel costs for organizing the disposal of the formed sludge.
