Design and construction of a venturi-based drainage cleaning machine

Abstract

This paper proposes to design and construct a venturi-based drainage cleaning machine. Drainage systems are essential for ensuring efficient wastewater management. Over time, these systems can become clogged with debris, causing blockages that result in a range of problems, such as flooding and sewage backup. The proposed machine utilizes the Venturi effect to create a vacuum that draws debris from the drainage system. The system comprises a series of nozzles that direct high-pressure water jets to dislodge the debris, while the vacuum created by the Venturi effect sucks it out, making it suitable for use in both residential and commercial settings. The construction of the machine involves sourcing and assembling the necessary components, such as the pump, motor, and nozzles. Once assembled, the machine was testing for its effectiveness in cleaning various types of drainage systems, but it failed to produce a suction force that sucks out the sediment and the water flushed for disintegration. This can be due to many different factors like pressure differences between the inlet and throat diameter was not created enough, there could also be inadequacies in fluid properties like temperature and viscosity of the fluid. The main objective of this machine was to create a suction force and also the disintegration of the sediment.
