Problems solved by technology

Furthermore, the glues disclosed in the prior art for incorporation into the material cannot always be satisfactorily incorporated into the material, since considerable inhomogeneities develop in the distribution of the glue itself
Also, the injection of the glue currently causes a high degree of contamination of the walls, resulting in a loss of yield, and requires intensive and frequent cleaning, causing frequent interruptions of work by the manufacturer

Embodiment Construction

[0011] Refer to the above figure 1 , the device of the invention comprises a bulk material feeder 2 provided with a lower discharge opening 24 through which the bulk material 100 flows by gravity along the falling direction Y. Purely by way of example, the power source is represented in the form of a hopper 21 provided with two accelerating rollers 22 , 23 facilitating the co-feeding of the bulk material 100 to the discharge opening 24 . However, feeding of the bulk material 100 to the discharge port 24 may be accomplished by gravity alone, without the aid of speeding rollers, or by pneumatic conveying or any other means.

[0012] By way of example only, the bulk material 100 may be in the form of wood fibers, shavings, or chips.

[0013] The injector 3 is preset for injecting a fluid, in particular glue, into the bulk material 100 . Along the falling direction Y of the loose material 100 , the injector 3 is located below the power source 2 . In particular, the injector 3 i...

Abstract

A device for injecting a liquid inside a flow of loose material, comprising: a feeder (2) for loose material (100) having a lower discharge opening (24) through which the loose material (100) falls along the Direction (Y) of flow; the injector (3), predisposed to inject fluid onto the bulk material (100), is located below the discharge opening (24) and thus positioned inside the flow of the bulk material (100).

Description

technical field [0001] The invention relates to a device and a method for injecting a liquid into the interior of a flow of bulk material. In particular, the invention relates to injecting glue by spraying into a stream of loose wood material. Background technique [0002] Currently known methods for adding glue to a flow of loose wood material involve spraying the glue inside a mechanical or pneumatic mixer, or injecting the glue by gravity onto the flow of loose wood material. [0003] Glue is usually applied from the outside. In particular, the injectors are arranged on the mixer housing or, in the case of gravity spraying, on the sides of the flow, usually on both sides, with the spraying direction perpendicular to or slightly inclined to the flow direction. This can cause serious drawbacks. First, a large amount of glue is dispersed into the environment, which in turn increases the pollution of the working environment. The glue scattered into the environment is also...
