Resumen
Pollution by plastic material in our city has caused the need for an efficient recycling method for water storage tanks made of low-density polyethylene, the proposal of this project was born before the possibility that the city of Riobamba has water 24 hours a day. Once the Alao Maguazo Project was completed, the design and construction of a shredder was carried out to recycle water storage tanks for residential use. To know the availability of the material, a survey was carried out among the inhabitants of the city of Riobamba, we obtained information on how these tanks were disposed of and that there is no way of recycling for this specific material. It was based on the design of the shaft, the motor was selected based on the torque necessary to crush the material, a power transmission using pulleys was chosen, and a rotor with oblique cutting blades was designed to obtain the highest cutting force, the frame was assembled by bolted joints to avoid fractures in welded joints, the pulleys and flywheel were ground and balanced to prevent vibrations in the system, and a single-phase motor starter was installed to control the on-off system of the machine. Finally, the performance tests were carried out, 250 x 250 cm sheets were introduced into the machine and 0.5 x 0.5 mm flakes were obtained, the temperature of the bearings was taken to confirm that there was no overheating after one hour of work. The noise generated by the machine was found to be within the acceptable range for workshop work. It is recommended when operating the machine that the operator has all the personal protective equipment.
