PART I-ABSTRACT

BACKGROUND: A can crusher is a device used for crushing empty aluminum soda cans for easier storage in recycling bins. For those who are frequent recyclers, their recycle bins may fill up very quickly. The can crusher gives extra space by crushing and flattening aluminum cans.

SCOPE: Design and build a pneumatic system that will function as a can crusher, fed by a chute and crushing two cans simultaneously. The cans will be packed manually and the system will be operated by a user. When the system is switched ON and the gate of the chute is opened, the cans will slide and then will be pushed by an actuating cylinder towards a metal block. When a can is crushed it will slide through a slot in the bottom and then fall into a collection basket.

As my team and I distributed the tasks, we agreed that I would supervise the project. As supervisor, I helped design the device as well as perform the required calculations. I also helped in the selection and purchasing of the components for the pneumatic system. I suggested that my team mates would take over on welding and fabrication as they are more experienced than me. While Ahmed took the role of selecting the materials used as he has experience in working in the steel industry.

PART II-DETAILSENGINEERING UNITS:

- Pressure: Pascal (Pa)- Force: Newton (N)- Dimensions: meter (m)

ENVIRONMENTAL CONDITIONS: The can crusher device was designed to operate in ambient conditions.

ASSUMPTIONS: It was assumed that a force of approximately 350N is needed to crush an aluminum can, therefore we set a minimal force of 1000N (1kN) to crush two cans.

MATERIAL: Aluminum was used to fabricate the crushing chamber and crushing plate, while carbon steel was used to build the table and collection basket.

CALCULATIONS:

Given: (Bore Size = 25mm) & (Force required = 1KN) & (Pressure =??)

Using the following equations:

- A=π r2

- P=F / A- V = Area x Stroke Length

It was calculated that a minimum pressure of 2MPa is needed to operate the can crusher.

BUILDING STEPS:

- 5 plates of aluminum were cut, 4 for the chamber walls and 1 for the crushing plate

- Sides of the plates were drilled with threaded holes to fit screws- Openings were drilled into one of the plates to allow the cylinder to fit in- Two of the plates were attached to clamps that could be fitted onto the

table- Pneumatic system was assembled as shown in circuit diagrams (see

appendix)

RESULTS: The device was tested by connecting it to 2 different compressors. When the first compressor was connected, the crusher was able to crush two cans with no problems faced. When the second compressor was connected, the crusher could only crush one can at a time, probably

because the compressor could not supply sufficient pressure. Overall, the device performed well and met our primary goals.

PART III-CONCLUSION AND RECCOMENDATIONSThe end-product of the project had minor deviations from the initial designs. No chute was fabricated due to the complexity of the fabrication process and the lack of both material and time. No safety interlocks were added to the system, a double acting cylinder was used rather than a spring-equipped single acting cylinder and a manual directional control valve was used instead of an electronic solenoid valve. Nonetheless, the device functioned properly crushing two cans when supplied with the correct amount of pressure. The main goal of the project was to design and build an environmentally friendly device that will aid in the packing of recyclable material (in this case aluminum cans) and this goal was met in our device. The device could be improved by applying the following adjustments:

- Tilt cylinder 90 degrees so that shorter tubes could be used and to prevent unwanted bundling.

- Add a portable compressor to the table so that the device could be used in locations where a compressor could not be provided.

- Add safety features such as a transparent safety guard and a system that will not allow the piston cylinder to extract or retract when the guard is not in place.
