Fishtail ISERCO

Fishtail

Fishtail

The fishtail is a metal plate welded or screwed into the outlet cone of the bin activator. This plate leaves a gap of 3 mm from the inside of the outlet cone.

The fishtail consists of an equilateral triangle always positioned pointing upwards, base downwards. The compressed air blown by this fishtail creates a blade of air that is inserted between the cone and the product itself. This blade has a vertical mechanical effect from top to bottom in the direction of gravity. During the operation of the fishtail, the friction forces between the inside of the cone and the product will disappear. The action of the fishtails does not cover 100% of the cone’s surface, but it breaks the horizontal and circular pressure balance of the powder inside the bin activator. Although this is not the objective, the air injected into the fishtail, relaxing in its action, presents a fluidizing action to the product. The relaxed air of each fishtail will leave the inside of the bin activator with the product, without putting the product under pressure.

Flexible sleeve with tightening collarsClamping rings

Flexible sleeve with tightening collars

Flexible sleeve with tightening collars

The flexible sleeve with tightening collars is installed at the outlet of the bin activator. Its purpose is to provide the seal between the bin activator, which moves, and the downstream device, which is stationary. As a result, the vibrations of the bin activator will not be passed on to the downstream equipment. Its resistance to pressure
must be identical to the resistance of the connection sleeve.

This flexible sleeve with tightening collars also allows isolating the vibration emitted by the bin activator on the silo.

The sleeve is made of thermoplastic material. It has good resistance to abrasion, very good mechanical characteristics, and high resistance to different temperatures. In addition, the material of this flexible sleeve can be put in contact with foodstuffs. It complies with the FDA recommendations and European directives on the subject of food production materials.

Manual emergency slide plate

Manual emergency slide plate

Manual emergency slide plate

This device isolates the bin activator when a maintenance operation is required below the latter. The seal obtained is therefore relative.

This device includes a 180° peripheral slot on the outlet spigot of the bin activator outlet. During normal working conditions, this slit is covered with a rubber sleeve or collar. This slit allows the operator to introduce a plate, which fits into the inner spigot of the bin activator. This device has the benefit of never getting blocked. However, given its manual nature, this system can never be used to replace a conventional valve.

pneumatic accelerator ISERCO

Pneumatic accelerator

Pneumatic accelerator

It is a pneumatic device intended to improve the flowability of difficult and cohesive products. It can also accelerate the emptying of products with normal flowability in case of a lack of flow.

It helps the flow of cohesive powders that tend to clog the outlet of the bin activator. Indeed, the pneumatic accelerator generates a compressed air flush towards the outlet of the bin activator. The mechanical effect of this air flush is to remove the product blocked in its area of action.

The use of a pneumatic accelerator facilitates the restart of a powder flow after a prolonged stop of the bin activator for example.

Poke hole ISERCO

Poke Hole

Tuyauterie de ringardage (poke hole)

This device is composed of a sloped tube that is directed towards the outlet of the bin activator. This device is used to perform tasks inside the bin activator when the latter is loaded. The poke hole must never be used for fusing products, (e.g. hot plaster). The opening of this pipe is hazardous. All specific precautions must be applied.

U-type sleeve

U-type sleeve

U-type sleeve

The U-type sleeve is held between the outlet flanges and the bin activator. Its function is to ensure the seal between the moving bin activator and the static recovery unit. It allows isolation of the vibrations produced by the bin activator on the equipment positioned downstream.

This sleeve can be put in place of the flexible sleeve with tightening collars. This sealing system is perfectly adapted to withstand higher pressures than with a flexible sleeve. The installation of this seal requires a welded flange at the bin activator outlet. Before installing this sleeve, make sure that the flange welded to the downstream device is identical to that of the bin activator.
