CAPACITY OF UP TO 2,000T/H
It meets the most demanding vertical transport needs for cereals, granulated or bran products. TNL TECNAL's centrifugal elevators are produced within the strictest quality standards and are made up of modules, one of which is the Driving Head.
This component is where the drive is mounted. The displacement speed of the belt, after turning the driving pulley, causes the product to be thrown from the buckets towards the Discharge Spout.
It is also equipped with a “breather” for air removal, a manhole, a bushing hatch and, depending on the model, with explosion vents.
In the lower head, also known as the foot of the elevator, the material to be conveyed is directed to the buckets by the side feed spout.
There are two types of lower head: conventional and self-cleaning, which can be provided, depending on the project's needs. The difference lies in the belt tensioning system. In the conventional head, only the pulley is displaced, and therefore the distance from the bucket to the bottom is variable.
In the self-cleaning head, the entire assembly is displaced and therefore maintains a constant distance between the mug and the bottom, which allows total collection of the material. The pulley shaft is supported by two bearings. It is recommended to install a rotation sensor on this axle. In the bearings, automatic lubricant and temperature sensor can be installed, according to the customer's request. To carry out maintenance, two cleaning mouths are inserted.
The elevator is supplied with types of flights according to the needs of the project. The items below are examples of some types of bids:
- Single Throw: Makes up most of the lift's bids;
- Section with Guide Roller: Installed, in pairs, on the "legs" of sections close to the lower head and upper head, the guide rollers have the function of preventing the elevator belt, when misaligned, from coming into direct friction with the internal sides of the bids, causing wear to them;
- Launch with Explosion Mouth: It has a small area configured with sheet metal sized to break under any explosion intensity, preserving the rest of the elevator in case this incident occurs. Its installation is usually alternated with simple flights, and it should be mounted preferably on the opposite side of the stairs and/or walkway. In cases where this is not possible, choose the side where there is less traffic of people;
- Launch with Flame Damper for Explosion Mouth: When the lower part of the elevator is mounted inside the shaft, the flame damper is mounted on the mounting flange of the explosion mouth in order to minimize the intensity of damage from an explosion in confined space.
- Lance with Guide Roller and Explosion Mouth: Depending on the assembly layout of the flights, in specific projects, guide rollers and explosion mouths may be installed in the same flight.
- Lance with Guide Roller and Flame Damper for Explosion Nozzle: In specific projects, the installation of explosion vents with flame dampers and guide rollers may be installed in the same flight.
- Lance with Inspection Holes: Installed, as indicated in the project, in an accessible and safe place, it allows the visualization of the mugs in operation, as it has a frontal display in transparent material.
- Feed Lance: Installed just above the lower head, it feeds the product to the buckets in elevation, through a lower opening connected to the feed hopper.
- Feeding/Inspection Section: When there is no access for internal inspection of the section (via catwalks or the upper level of the well), the inspection ports are installed directly on the feeding section.
