RU1801546C - Sand trap with hydraulic elevator system for removal of sediment - Google Patents

Abstract

Usage: mechanical water treatment. SUMMARY OF THE INVENTION: when sand is removed from a sand silo 2, a working fluid is supplied via a pressure pipe 9 to a nozzle 4 with an open valve 10 and an open valve. The working fluid enters the chamber 8 and simultaneously through the pipe 13 with the open valve 14 into the lower piston space of the cup 11, acting on the annular piston 12, which moves upward along with the conical baffle 7. In this case, the sediment is loosened by the liquid and crawls into the chamber 8. from where it is vented into conduit 5. When the piston 12 rises to its highest position, it is operational. liquid from the piston space enters the signal pipe 15, after which the valve 6 opens and, with the valve open 14, the sediment is removed from the hopper 2. 1 zp piano, 1 silt, 18 fe

Description

The invention relates to the mechanical treatment of water and can be used to treat potable and wastewater.

The aim of the invention is to increase the reliability of the sand trap by preventing clogging of the elevator nozzle.

The drawing shows the proposed sand trap, a longitudinal section.

The sand trap with a hydraulic elevator sludge removal system contains a flow tank 1 with a sand hopper 2, in which a hydraulic elevator 3 with a nozzle 4 and a pressure pipe 5 for removing sand, equipped with a valve 6, and a chamber 8 formed by a conical partition 7 are located in which the nozzle-4 of the hydraulic separator is located 3, connected to the pipeline 9 by the supply of a working fluid equipped with a valve 10.

A conical partition provided with an annular shoulder resting on embedded parts in the side wall of the sand bunker 2 has an angle of inclination greater than the angle of inclination of the natural slope of the sand in the wet state.

Cup 11 is sealed coaxially with the support pipe 5, in which an annular piston 12 is located, which is rigidly connected to the conical baffle 7, the lower piston space of the cup 11 is connected by a pipe 13, equipped with a slide valve 14, a pipeline 8, and the upper piston space with a signal a pipe 15 provided with a valve 16.

Sand trap works as follows.

When removing sand from a sand bunker. Para 2, the working fluid is supplied through the pressure pipe 9 to the nozzle 4 with the open valve 10 and the open valve 16. The working fluid enters the chamber 8 and simultaneously through the pipe 13 with the open valve 14 into the lower piston space of the nozzle 1.1, acting on the annular

the piston 12, which moves upward along with the conical baffle 7. This loosens the sediment with the working fluid and slides it into the chamber 8, from where it is ejected into the pipeline 5. When the piston 12 rises to its highest position, the working fluid from the sub-piston space enters the signal pipeline 15, after which the valve 6 opens and, when the valve is closed 14, the sediment is removed from the hopper 2.

In the proposed device, clogging of the elevator nozzle is prevented, since the structural design of the chamber completely eliminates the ingress of large contaminants into it. This increases the reliability of the hydraulic elevator system for removing sludge and sand traps in general, and simplifies its operation.
