Diseño y construcción de una máquina compactadora de residuos sólidos para la empresa Curtiembre Quisapincha

Abstract

In this document the design and construction of a solid waste compactor machine for the company CURTIEMBRE QUISAPINCHA is shown. A bibliographic review was made regarding the solid waste compaction processes, and the current situation of the company was described in terms of the processes, volume and classification of the solid waste generated. For the establishment of the technical specifications of the machine followed the Methodology of Concurrent Design using: the House of Quality, Functional Analysis, Determination of Modules and the ordinal method of weighted criteria. The components were designed such as: the collection trays, the auger and the jacket according to the specifications and requirements which were analyzed and simulated by finite elements and other components selected from catalogs. Next, an analysis of the total costs of manufacturing the machine was made. The results obtained show that the machine has a production capacity of 819,11 kg/h complying with the user's requirement. Once the testing stage was carried out, it was necessary to decrease the clearance between the discharge nozzle and the worm in the conical section to improve the compaction, in the same way the depth of the channels of the worm screw thread was increased to 30 mm. The problems of lack of compaction and the difficult entry of waste were corrected.
