Description

Изобретение относится к сооружениям для отстаивания сточных вод.The invention relates to facilities for sedimentation of wastewater.

Известен отстойник, содержащий резервуар, с приямком и приспособлением для сбора осадка в него в виде ходовой тележки, совершающей возвратно-поступательное движение, верхний и нижний скребки со штангой W·Known sump containing a tank with a pit and a device for collecting sediment in it in the form of a running trolley, making a reciprocating movement, the upper and lower scrapers with a rod W ·

Это устройство сложно в изготовлении и ненадежно в работе.This device is difficult to manufacture and unreliable in operation.

Цель изобретения - повышение эффективности использования устройства за счет устранения трудоемких операций и упрощения процесса сбора осадка. ^! The purpose of the invention is to increase the efficiency of use of the device by eliminating time-consuming operations and simplifying the process of collecting sediment. ^!

Указанная цель достигается тем, что устройство снабжается уложенным на дно и стенки резервуара водонепроницаемым синтетическим материалом и трубопроводами сжатого воздуха, размещенными между материалом и дном отстойника.This goal is achieved by the fact that the device is equipped with a waterproof synthetic material laid on the bottom and walls of the tank and compressed air pipelines located between the material and the bottom of the sump.

На чертеже схематично изображен предлагаем/й отстойник.The drawing schematically shows the proposed / sump.

Водонепроницаемый синтетический материал 1 укладывается на дно и стены отстойника 2. Под ним проложен трубопровод с выпускными отверстиями 3 для подачи сжатого воздухаWaterproof synthetic material 1 is laid on the bottom and walls of the settling tank 2. Underneath it is a pipeline with exhaust holes 3 for supplying compressed air

Отстойник имеет на дне приямок 4 для сбора осадка.The sump has a pit 4 at the bottom for collecting sediment.

Устройство работает следующим образом.The device operates as follows.

* · По мере накопления осадка на водонепроницаемом синтетическом материале в сторону приямка 4. После сползания осадка сжатый воздух опускается и отстойник принимает первоначальный вид.* · As the sediment accumulates on a waterproof synthetic material in the direction of the pit 4. After the sediment creeps, the compressed air descends and the settler takes its original form.

Предлагаемой отстойник позволяет отказаться от сложных и недостаточно надежных в эксплуатации различных механизированных скребков и илоскре15 бов, а в отстойниках вертикальных и двухъярусных от устройства трудоемкового конусного дна. Осуществление горизонтального дна вместо конических и наклонных позволит умень-?The proposed sump allows one to abandon the complex and insufficiently reliable operation of various mechanized scrapers and sludge scrapers, and in the sumps vertical and bunk from the device labor-intensive conical bottom. The implementation of the horizontal bottom instead of conical and inclined will allow reducing

шить количество отстойников в связи с увеличением их емкости в час максимального притока, т.к, удаление осадка может производиться в часы их минимального притока.sew the number of sedimentation tanks in connection with an increase in their capacity per hour of maximum inflow, because the sediment can be removed during the hours of their minimum inflow.

Одновременно водонепроницаемый син· тетический материал служит гидроизоляцией для дна и стен отстойника.At the same time, waterproof synthetic material serves as waterproofing for the bottom and walls of the sump.

Claims

The invention relates to sewage settling facilities. A septic tank containing a reservoir is known, with a nozzle and a device for collecting sediment in it in the form of a walking trolley returning forward, the upper lower scraper with a rod l. This device is difficult to manufacture and unreliable in operation. The purpose of the invention is to increase the efficiency of using the device by eliminating labor-intensive operations and simplifying the process of sludge collection. This goal is achieved by the fact that the device is supplied with a waterproof plastic material laid on the bottom and walls of the tank and compressed air piping placed between the material and the bottom of the sump. The drawing schematically shows the proposed Lz1y settling tank. Waterproof synthetic material 1 is laid on the bottom and walls of the settler.

2. Under it there is a pipeline with outlets 3 for supplying compressed air. The sump has at the bottom of the tank 4 to collect sediment. The device works as follows. As sediment accumulates on the waterproof synthetic material to the side 4. After the sediment creeps in, the compressed air is lowered and the sump takes on its original appearance. The 1st 4th settling tank allows you to refuse from the complex and insufficiently reliable in operation various mechanized scrapers and scrapers, and in the vertical and double drainage basins from the device of labor-intensive conical bottom. The implementation of horizontal bottom instead of conical and inclined will reduce the number of settlers due to the increase in their capacity per hour of maximum inflow, since sediment can be removed during their minimum inflow. At the same time, the synthetic material serves as a waterproofing barrier to the bottom and walls of the settler. . Claims of the invention: A settling tank containing a reservoir with a jaw and a jig

collection of sediment in the case of wetting, and with the fact that, in order to increase the efficiency of its use, due to labor-intensive operations and to simplify the process of collecting sediment, it is provided with waterproof

material and compressed air piping placed between the material and the bottom of the sump.
