Centralised Vacuum System
This system is commonly applicable in all processing industries, be it steel, cement, foundry, power plants, textiles or ceramics. The layout and type of systems change with the application in various industries. It is also determined by the size of the area where the system is to be installed, the dust generating areas and the quality of dust (or the density of the material that has to be picked up). Accordingly, the vacuum system is designed for a certain velocity and the piping system laid out depending upon the amount of collection and the number of collection points.
Forbes Pro is in the process of installing a big system in Tata Steel at Jamshedpur which is engaged in iron ore processing. Application is basically online collection of spillage of dust, sintered powder and granules fallen on the floor, underneath the conveyor belt, in the machinery, structures and all over during processing and transferring the same through the conveyor belt.
During the process of transferring the sintered powder through the conveyor belt, there is spillage on the floor and the entire area becomes very dusty. The process works like this: online suction of dust, powder and granules from various sources through the centralised vacuum system and collection of the same into the hopper and discharge of the collection back into the system. There is 100% collection / recovery and no wastage.
Operating principle
- The Centralised Vacuum System consists of a vacuum unit ‘1’ which creates vacuum inside the hooper ‘2’ into the piping ‘3’ & ‘4’ and finally, into the hose & floor nozzle ‘5’.
- The material spilled on the floor is sucked into the nozzle through the hose ‘5’into the pipings ‘3’ & ‘4’ and discharged into the hopper ‘2’. From the hopper, the material can either be collected in big bag ‘6’ or back into the system ‘7’ for recycling.
- The size of the system depends on the number of operators working at a time, the farthest distance of the material to be transferred, the rate of transfer required, the density of the material, the characteristics of the material, etc. The system runs continuously 24×7 with automatic discharging, cleaning of filters through pulse jet cleaning at a desired frequency which can be set by the operator.
- The piping could be of Zn plated, galvanized or SS connected by junction sleeves with smooth bends connected with spring loaded flap opening at the end coupled with a micro switch which automatically starts the machine once the flap is opened and shuts of the machine immediately when the flap is closed by the operator.
- The vacuum system ranges between 2KW to 100KW with a transfer rate for 50kg/hr to 10 tonnes/hr depending on the requirement of the customers.
Trim Extractors
For OEM’s packaging machines, handling bulk waste generated during the continuous process of trimming becomes difficult to handle. Be it a tablet manufacturing unit or other packaging units, the trim extraction system helps collection of bulk trimmings.
Trim extractor vacuum unit R-models are recommended to extract trim parts (paper, plastic, fibres, etc.) from the production or packaging machines in the industries as follows:-
Packaging – Extraction of various kinds of trim from packaging machines.
Textile – To extract continuous trim of threads cut from garments during manufacturing process in order to avoid machines stoppage and periods of inactivity.
Paper – For continuous extraction of paper trim and dust during finishing process in the production of paper goods.
Operations
The trim is extracted continuously and enters into the container ‘1’ through the inlet ‘4’ and recovered in the nylon liner ‘2’. Thanks to the position of the motor ‘3’ at the bottom of the machine. The liner is spread out and completely open and all products vacuumed in are neatly compacted at the bottom optimising the capacity of the container ‘1’. To empty the container it is sufficient to open the lid and remove the nylon liner.
Benefits of R-Trim machines
Improved production time – The trim extractor avoids all stoppages caused by the need to clean the machines.
Cleaner environment – the R models prevent waste products from contaminating the environment and working areas.
Top quality products – By removing the trims as soon as they are generated, allows to verify in real time if the finished products meet the high quality standards without clogging the cutting machines with waste materials. At the same time, the working environment is thoroughly de-dusted.
Better production organisation – The speed and ease with which the waste material can be disposed of allows to accurately calculate the amount of time required for this operation, improving the quality and organising of the manufacturing process.
Features
- Maintenance free
- Possibility to tightly compact of the long cuts, trims in the liner
- Wide range of induction motors for 0.85 KW to 4 KW
- Easy and quick disposal of waste material
- Quick visual level control thanks to the port hole on the lid.
