Brief system description for URS of Lifting & Tipping Device:
Tippler-Lifting and tipping device is a hydraulic device which is having an arm used for lifting and turning FBD bowl by 180 degree. It is used to unload FBD bowl material in to Cone mill or Multi mill or Oscillating granulator in a dust free way for downsizing or dry milling. The operation is completely dust free and eliminates manual handling or scooping.
The FBD Bowl is placed beneath the Tipper & inverted cone of the Tipper is lowered so that the brim flange of the bowl touches the inverted cone. Both are clamped together with quick fixing clamps. The whole assembly is raised.
The basic construction of the machine consists of :
- The equipment is designed with cylindrical body and tapered bottom with a large sized lid for easy cleaning process. They are made from stainless steel material such as SS 316 Non contact parts SS304 with matt finish
- Non metallic contact parts SS304 with matt finish, any material with food grade quality having no potential impact on the products
The Drive:
Equipped with frequency controlled drive. Large torque can be achieved even at low speed and because of its high regulating speed it is centrally driven by an electric motor
Bin
Shell-The shell consist of a square central part with conical frustums at one ends. This cone is provided with a butterfly valve used for discharge a powder. Top is square in shape and has a welded lid (manhole) from the top. The manhole is provided with a air tight cover & Gasket. Discharge- A manually operated butterfly valve is provided at the bottom for discharge. Mounting – The bin is provided with independent trolley to facilitate the bin loading and unloading in the arm.
Lifting Device:
Two ‘C’ frame structures are used to build a column. Column frame is connected with each other by top & bottom Plate. The column is then connected at the base on a revolving circle mounted on a thrust bearing. The circle is connected on the base plate. A hydraulic cylinder is mounted inside the column to support inside carrage, connected by chain and sprocket assy Inside carriage is connected to outside carriage & outside carriage holds the bin arm.
Lifting Arrangement- A system mounted on the hydraulic cylinder head lift the bin arm with a heavy designed carriage. The bin arm is mounted on a box inside the column which is guided by the bearing in a channel on two opposite sides inside the column.
Power pack- An MS powder coated tank act as the oil reservoir and also support the hydraulic circuit. The hydraulic power pack unit consists of a single gear pump coupled to flange mounted 3 phase electric motor suitable capacity with suitable bell housing and gear coupling.
The pressure is controlled by 2 relief valves. Two relief valve controls the high maximum allowable pressure and return pressure of pump. Both relief valves shall be direct operated. A pilot operated check valve is provided to lock the pressure in the cylinder so that it will not come down when not desired.
A solenoid operated direction control valve controls the cylinder movements upwards as well as downwards This is operated by a press down push button. Y piece. A “Y” shape connection is made to discharge the material in two charging ports of the compression machine
Platform:
A sturdy platform is made and installed on the machine, to allow the y piece & the IPC bin to rest on it
Electrical chamber and mechanical chamber:
All mechanical components such as gears, motors, and moving belts, as well as electrical components such as wiring, switches, and MCBs, are installed in this segment.
