Abstract

The invention relates to sewage and relates to a constructive implementation of a device for the removal of wastewater in semidividual and all-sewage systems, namely, shower drainage. The goal is to ensure the constancy of the discharge of the waste liquid discharged for cleaning while reducing the length of the chamber and preventing the ingress of floating contaminants into the water body. The drainage lid comprises a vertical guide shield 9, made in the lower part along the length with a protrusion 10 having a wedge shape in longitudinal section. The shield is installed in the chamber 1 on the overflow tray 8 with an emphasis on the chamber walls and at an acute angle to the longitudinal axis of the chamber 1. At the end of the interceptor collector 6 there is a knee 7, the inlet of which is placed in the insert 11 formed in the bottom 3 of the chamber 1. 1 zp f-ly, 4 ill.

The invention relates to sewage and relates to a constructive implementation of the device for removal of wastewater in the systems of semi-separate and all-sewage, namely, rainfall

The goal is to ensure the constancy of the discharge of the waste liquid discharged for cleaning while reducing the length of the chamber and preventing the ingress of floating contaminants into the water body.

FIG. 1 shows a shower, a longitudinal section; FIG. 2 - section A - A in FIG. one; in fig. 3 - section B - B in FIG. 2, FIG. 4 - section B - B in FIG. 2.

The drainage chamber consists of a chamber 1 having an overlap 2 and a bottom 3, a supply manifold 4. a discharge manifold 5 of smaller diameter, an interceptor collector 6 with an elbow 7, a drainage chute 8 located flush with the supply 4 and a discharge manifold 5,

a vertical guide plate 9 with a protrusion 10. having a wedge shape in longitudinal section located on the overflow tray with an emphasis on the walls of the chamber and at an acute angle to the longitudinal axis of the chamber and at 11 formed in the bottom of the chamber

Sewage through the inlet collector 4 enters the drainage system. At low flow rates, the wastewater flows freely into the outlet collector 5 of a smaller diameter. At high costs, the protrusion 10 divides the water flow horizontally into two parts. The lower part of the flow, due to the projection in the longitudinal section in the form of a wedge, with its inclined plane that receives the load from the incident flow, equals the curvature of the shield 9, thus eliminating discharge manifold 5, ensuring the operation of the discharge manifold without backwater

The upper part of the stream, containing a large amount of oily and floating substances, runs over the protrusion 10 and, meeting on its way, the shield 9 is dumped into the chamber 1. In the lower part of the chamber there is an accumulation of sewage strongly saturated with floating substances, but due to the water trap device, formed by the knee 7, placed on the interceptor collector 6 and half-capped in at 11, the wastewater discharge chamber is discharged without floating substances and floating substances harmful to the water basin accumulate in the camera. The floating substances accumulated in the chamber are occasionally pumped out with a special machine and taken to the treatment plant.

Reducing the dimensions of the shower chamber makes it more economical, while ensuring the consistency of the flow rate is liquid; which allows for cleaning and also prevents the discharge of floating pollutants into the water body, which ensures good sanitary quality of the structure, as it allows using the shower chamber as a storage device.
