Description

11039 The invention relates to catalysis and is concerned with arranging for the reception of sewage disposed at KATS (the sewage network in front of pumping stations. Sludge is carried out by flushing with a stream of water from a fire engine. However, with this sediment removal, it is necessary to empty the tank beforehand, which is connected with its disconnection from the sewer network. network, and prevention of overfilling requires an increase in the diameter of the collectors to increase capacity, the network. The composition of the effluent and the prevention of precipitation of the sediment tray is equipped with a dragging device, made in the form of a working chamber, inside which the screw 2 is installed. A disadvantage of the known regulation ir: boiling vessel is low operational reliability due to incorporation into the contaminated liquid rotating metal parts Furthermore, the energy consumption are increased due to the need to install elektrodvigatepey. The purpose of the invention is to reduce operating costs and increase the reliability of the control capacitance. This goal is achieved by having a regulating vessel containing a rectangular tank with vertical partitions, an overflow gutter, supply and discharge pipelines and a trapedeal line. the bottom in which the longitudinal tray is made, partitions are installed across the tank to longitudinal perspiration. don't overlap it. Pristomlotoksnabzhenstrustrupravl Yu. rollers, and the partitions are equipped with rebar tray gates,;. FIG. Figure 1 shows a regulating tank with transverse partitions, the edge of which is higher than the maximum water level ;;, in the tank, the gates are open, the longitudinal rae cut; in fig. 2 - the same, gates are closed; 9OO in FIG. 3 - then ke, vdv in the plan; in FIG. 4, a-A-A in FIG. I; in fig. 5 - control tank with transverse overflow lines in the tank, longitudinal section; in fig. 6 same plan view; in fig. 7 is a section BB in FIG. 5. In tank 1c with trapezoidal bottom 2, transverse baffles RODKI 3 are expanded, dividing the tank into successive sections. The angle of inclination of the walls of the bottom 2 is greater than the angle of sliding of the sediment. In the bottom 2 is made pro-. The longitudinal tray 4, the partitions 3 that reach the bottom, do not overlap this tray, together with its walls form the overflow holes. It is advisable that the angle of inclination of the walls of the rollers be greater than the angle of creep of the sediment. On the partitions fixed gates 6, which can be equipped with an electric drive. The DDD of the wastewater supply is served by the pipeline 7, for its withdrawal - the pipeline 8 connected to the suction side of the pump 9, the discharge pipe of which is connected to the pressure pipe Yu. I In the direction from the inlet pipe. water 7 to the discharge pipe 8, bottom 2 of tank I and the bottom of tray 4 are sloped. In tank I, there is a transverse recess trough 11 with a branch pipe 12, in which case the partition wall 3 (FIG. 5) is located below the ridge of the channel. The regulating tank works in the following way: - Sewage water flows through pipeline 7 into reservoir I. Sediment, which is within the first section, limited by the end wall of the reservoir and the direction of water movement through partition 3, slides along the walls of the bottom 2 into tray 4 to flow in of water, B1, flows from pipe 7 with pipe speed 7, and moves along the tray to the first transverse partition. Here it is swept up by the flow of water, flows at povipieny speed through the opening holes under the first transverse partition, and together with the sediment that falls within

the second section is moved along the tray 4 to the second transverse partition

Similarly, the sludge continuously moves along the entire length of the chute, is taken to its end together with Vs with waste water through the discharge pipe, 8 by pump 9 and through the pressure pipe Z is fed to the treatment plant sites or is fed into the sewage collector. MO

In the presence of strand rollers 5, the sediment that falls in the interstitials of the first section, is picked up in the tray 4 by the flow of water flowing out of the pipeline 7, moves through 15

the roller ridge and crawls to the first perbach septum 3; here it is picked up by the flow of water flowing through the bypass hole under the first transverse partition, then along with the 20 sediment that falls within the second section to the ridge of the roller I nepovic through the last I COB-ridge. a local with sediment, located in the second section after the ridge of the valikb, passes to the second transverse partition.

Similarly, the kenpebi Bie sediment moves along the length of the tray.

Thanks to the straightening rollers, the number of cross partitions of river partitions can be reduced, as well as reduced pro-.

longitudinal slope of the bottom and bottom of the tray, which reduces the depth of the tank.

With the help of gates, the area of the bypass openings is regulated and, thus, hydrodynamic openings are created, at which the most efficient sludge was removed.

IF, without stopping the discharge of water through pipeline 8, to close the gates 6 sequentially, starting from the most distant from this pipeline, the water level in the first section will be higher than in the second, in the second - higher than in the third, etc. the opening of the gates in the same sequence is provided by washing the sediment in the known device. With the control unit of the electric drives of the gates, this mode can be controlled automatically.

At least the gate on the last partition in the direction of water movement and part of the drainage water with these substances is removed through the chute II and the discharge pipe 12, which is connected to the outlet of the reservoir 8 through the chimney 8, to remove the floating substances.

In the described control of the capacity, the sediment is effectively removed without additional energy consumption. CAPACITY is simple and reliable in operation
