Description

one

The invention relates to sewer systems, in particular, to installations for pumping and transporting. Wastewater from an intake reservoir to wastewater treatment plants and can be used in the sewer systems of cities and industrial enterprises for pumping wastewater containing large inclusions.

A known installation for pumping wastewater containing large inclusions without IH extraction, including a flow pipe, a pump with a suction pipe lowered into the receiving tank AND a pressure pipe having a grate, over which a check valve is installed, a filter equipped with a filter, overflow I gravity pipes, the last of which are connected by means of a check valve to the pressure pipe of the pump installed above the receiving tank I.

In this installation, the grate is perpendicular to the flow of wastewater AND from the gravity pipe, the large inclusions contained in this flow linger on the grate, quickly blocking it and preventing further flow of wastewater through this grate to the receiving tank, which negatively affects installation mode as a whole.

The aim of the invention is to increase the efficiency of the installation by reducing the clogging of the grate and CLEANING it with the incoming stream of wastewater.

This is achieved by installing a special sedimentary chamber in the discharge pipe behind the inlet, made in the form of a bend installed by a DOWN bend, and the grate is located between a check valve installed on a gravity pipe and the sedimentary chamber flush with their internal surfaces.

The surfaces of the body of the lattice check valve (its thickness in this case does not matter and can be considered as a plane) and the chambers are mated as; a single smooth whirlpool that has the appearance of a knee, and the grate is located near the entrance to this knee above its average hour. Thus, the incoming flow as if SLIPS along the grille, at the same time, the passage through it to the receiving reservoir and the village of the big elbows into the srey part of the knee,

PROBLEM AREA: e aka oa aa b lesca ate after a long distance round-trip of a school, a scientific research institute, after all, there are large inclusions before the ejection. proceed destructively in a weighted state, and in a well-known installation on a lattice in a considerably intact state,

FIG. 1 shows a plant for pumping wastewater; a general view; Fig 2 - the node J in Fig „1,

- The sewage pumping station consists of an integrated chamber I, having a filter 2 and connecting to the machine room 3 stations using an overflow pipe 4 and a suction pipe 5. which is connected via a non-return valve to the having a grid 7 of the discharge pipe S of the pump 9 with suction pipe 10, - lowered into the front tank 11 ,. The reservoir 11 is trimmed with oi ivihufinHHoro placed with a horizontal hermetic overlap 12 and csfisan with the atmosphere through a vector tube 13 ,. to which the pipe is connected 4.

. A sediment chamber 14 in the form of a knee is installed on the discharge pipe O behind the restoration 7 (by bending of the crankshaft).

Works us. in the following way,

When the e: pump is turned off, the incoming liquid from chamber 5 flows through the installation of an inclined gravity flow pipe 5 and then through a check valve 6, the grating 7., and a pump 9 n suction pipe 10 in the liqueur.

Large inclusions, concomitantly in waste liquid, złpper: 1i; iputs on lattice 7 to gradually step through the stream coming through inclined gravity flow pipe 5 starch of water into chamber 1 This ensures unallocation of clogging of the outflow and oi; .n i.e. assumptions are constructed in water,

In the process Z.pol5; e: -5K of the reservoir .1, the beater is displaced from it through the valve of the clamping tube 13, and the air from the Essena pipe 10 and pump 9 is transmitted through the grate 7, which are displaced into the chamber 14 When the pump 9 is turned on, the check valve 6 under pressure created by the pump (closes, stopping the flow of bone through the gravity pipe 5, Large elutes washed out, removed by the flow of fluid through the discharge pipe 8, to ensure better removal from chamber 14 into it CONCLUSION the axis of the section of the pressure pipe with installed in it decides oh 7 forms an acute angle with the axis of the downpipe {5 in the drawing plane). ,

When the pump 9 is stopped, the pressure in the supply pipe S, the check valve 6 opens, freeing the fluid path through the gravity flow pipe 5. The process repeats.

TsiKHM with a deflector, by reducing the clogging and rematting, the unit operates more bluntly than before: as compared

 the invention

The installation for pumping waste BORf contains large inclusions without removing them, including a filter chamber with, with; a .motor tube, supplying water to the receiving tank, a pump with a suction tube and a pressure tube, having a grate and connected by means of: -: a check valve to , gravity pipe, about t l n ch and you sch. . so that, with: the goal of increasing efficiency by reducing clogging of sieves and cleaning it with an incoming stream of sewage, the installation is equipped with a sedimentary chamber made in the form of a knee and sedicated with gravity and pressure pipes, and the lattice is located between the check valve and the sedimentary chamber flush with their anutra surface of them, yes,
