Styrocontrol 1.8

Welding, sawing, drilling, screwing

BILL OF MATERIAL • Mdf sheet (9 – 12 - 15 mm) • Venturi system • Suction hose (2m) • Pneumatic cylinder • 2 pneumatic pedals • Pneumatic tubes • Push-in T connector • Pneumatic tube connections • Pressure regulator • Teflon tape • Aluminum profiles • Straps • Steel profile 40 x 40 x 2 • Steel profile 35 x 35 x 2 • Paint/ spray pistol/ spray can • Bolts, nuts, clamp rings, screws • Silicon • PP tube with screw-thread at both ends • PP valve • Cloth

1 DESCRIPTION The silo is made of mdf sheets. Tests showed that this material is an optimal solution to prevent static electricity of the small styrofoam pellets. The size of the silo depends on the desired capacity of the system. The diameter of the hole at the bottom determines the flow rate of the pellets. The flow rate is independ of the amount of pellets left in the silo. First the mdf sheets need to be sawn and afterwards fixed to together by using screws. It is important to seal up the silo completely with silicon or putty to prevent unwanted escaping pellets. Optional: perspex can be used at the front side of the silo to see the remaining amount of pellets in the silo.

SILO

Mdf sheets, screws, silicon/putty

Depends on the used materials

2 DESCRIPTION The cover at the top of the silo is made of a wooden frame. A cloth is stretched over the frame and fixed with staples. When pellets are sucked up by using the venturi system, air also enters the silo. The cloth allows the air to escape without releasing the small pellets as well.

SILO COVER

Saw machine, drilling machine, stapler, screws

3 DESCRIPTION A valve is fitted at the bottom of the silo. This valve assures there is no unwanted flow of pellets when the system is closed. A pneumatic cylinder is connected to an mdf sheet, which is fixed on the back side of the silo. Because of the cylinder’s high forces on the handle of the valve, the system is strengthened with two aluminum profiles. The cylinder should be fixed at an angle of 45 degrees . At the bottom of the valve, it provides screw thread which is useful when you want to mount a small nozzle.

5 DESCRIPTION The silo is fixed on a metal frame, using 4 bolts. The frame is adjustable in height. It consists of square profiles of 40 x 40 x 2 mm and 35 x 35 x 2 mm that have been welded together..

SUPPORT STRUCTURE

3 hours

Metal saw machine, drilling machine, welding machine, spanners

The metal profiles have to be sawed at the required length

5 DESCRIPTION At the top of the silo a hole has to be drilled to fit the venturi system. The system is fixed on 2 aluminum U-shape profiles which are connected to the silo. By using bolts and nuts the system is easy to (dis)assemble. At the top of the venturi is a connector to fit a tube. The suction hose can be fitted on the venturi system. A clamping ring makes sure that the hose is fixed.

VENTURI SYSTEM

20 minutes

Manual saw, drilling machine, spanners

A venturi system

2 short aluminum U-profiles, bolts, nuts

Depends on the materials

3 DESCRIPTION The pressure regulator can be fixed onto the silo with a bolt-nut connection. Factories normally have a pneumatic circuit with a pressure between 6-7 bar. By using a pressure regulator, the air flow can be regulated which makes it possible set the suction speed for the pellets.
