Definitions
- This invention relates to fibre and particulate processing.
- this invention relates to a system for the treatment of fibres including wool and feathers in both their natural and particulate forms.
- Wool scouring is the practice of treating raw wool using various solutions in order to remove impurities such as wool grease, suint and dirt.
- a typical scouring process involves the wool undergoing a series of washes in various cleaning solutions, culminating in the drying of the wool in preparation for further processing.
- a typical modern plant features a continuous feed system by which the raw wool is fed across and through a series of "bowls" containing various cleaning products. Machinery is configured to distribute the wool evenly across each bowl, and submerse it in the cleaning product. The wool is squeezed through a roller system in order to remove the cleaning product before the next stage.
- a method of material treatment including the steps of:
- a material treatment apparatus including: a receptacle configured to contain material to be treated, and allow the ingress and egress of treatment fluid; and a conveyor configured to a) convey the receptacle to a treatment fluid application area; b) hold the receptacle in position while the material is treated by a
- treatment fluid and c) convey the receptacle from the treatment fluid application area.
- the preferred embodiment of material in the present invention is in the form of filamentous or particulate components including, but not limited to, wool, fur, flax, or feathers. Reference shall now be made to the materials as being fibres throughout the specification, but this should not be seen as limiting.
- treatment throughout this specification should be understood to mean any operation or procedure which alters the condition of fibres.
- the preferred embodiment of treatment in the current invention is the scouring, compaction, drying, heat treatment, dyeing, chemical treatment or extraction of fibres.
- treatment fluid throughout this specification should be understood to mean any fluid that can alter the condition of the material such as fibres.
- treatment fluid in the current invention can include air, water, detergent, acid, alkali, dyeing agents, bleaching agents, sand or micronised particles.
- preferred fluids can include air, water, detergent solutions, acid solutions, alkali solutions, dyeing solutions, chemical solutions and bleaching agents.
- the treatment fluid may be a lye solution.
- fluids may have varied temperatures, pressures and concentrations.
- Reference to egress throughout this specification should be understood to refer to the passage of the treatment fluid away from the fibres.
- Reference to a receptacle throughout this specification should be understood to refer to a means of containing fibres.
- a receptacle in the current invention is in the form of a rigid sided container, although possible embodiments include a basket or bag.
- the receptacle is an open topped container with rigid mesh sides.
- the mesh size is sufficiently small that fibres are unlikely to escape through the mesh - yet sufficiently large to allow ready ingress and egress of the fluid with respect to the fibres.
- the receptacle may include a means by which it is attached to and supported by the conveyor.
- the receptacle may include handles.
- the size of the receptacle may be such that it may substantially fit within the treatment fluid application area.
- Reference to a treatment fluid application area should be understood to mean the position within the apparatus at which the fibres located in the receptacle are brought into contact with the means of treatment.
- the preferred embodiment of a treatment fluid application area is in the form of a rigid sided container such as a bath which has been subdivided into a number of open- topped compartments.
- the treatment fluid application area may comprise two or more rigid sided compartmentalised containers.
- the treatment fluid may be circulated within the container, and that the container may allow for the replacement or alteration of the treatment fluid.
- the treatment fluid from later stages may be reused in an earlier sequence of the process for the next batch of material.
- the water used in the later stages of the cycle may be reused for the initial stages of scouring the next batch of wool.
- the high level of contaminants in the wool may mean that high levels of purity of the water used as treatment fluid is not essential. Water from the later stages (in which the wool has been cleaned) may therefore be used without a significant reduction in effectiveness. This may serve to improve cost efficiency - both in terms of reducing total usage and the waste disposal of same, and also associated costs such as heating the treatment fluid. It is also envisaged that a continuous or regular flow of clean treatment fluid may be introduced into the treatment fluid application area, with the most used, or
- the treatment fluid area may therefore include channels, or valves, between compartments or baths which facilitate the transfer of treatment fluid.
- a treatment fluid application area may be configured for the specific purpose of carrying out a chemical treatment or modification of the fibres other than by way of submersion.
- the treatment fluid application area may include a spraying or jetting apparatus.
- a treatment fluid application area may be configured for the specific purpose of drying the fibres. Drying may occur by convection drying, conduction drying, vacuum drying, application of centrifugal force, dehumidification or radio frequency drying. Reference to conveying throughout this specification should be understood to mean the causation of contact between the receptacle in which the fibres are located, and the means of treatment.
- the conveyor can be driven by an actuator and reference to an actuator throughout this specification should be understood to be any means by which action or motion is achieved or initiated.
- an actuator in the present invention could take the form of a hydraulically or pneumatically driven piston, a chain or gear or screw drive, a pulley based drive system or winch.
- the preferred embodiment of conveying in the present invention is composed of a cradle which supports the receptacle and can lift or lower the receptacle relative to the treatment fluid application area.
- the conveying system is capable of supporting and conveying more than one receptacle at a time.
- a cradle throughout this specification should be understood to mean a frame intended to support a piece of equipment.
- the cradle is configured to adjust the elevation of a receptacle or receptacles.
- the preferred embodiment of the cradle in the present invention is in the form of parallel rails by which a receptacle may be supported, and a plurality of actuators to allow for a change in elevation of the rails.
- the actuators are of a linear configuration and powered by pneumatic or hydraulic pistons, rams or motors or electromechanically such as an electric motor coupled to a screw. It should be appreciated that the receptacles may be manually positioned over the treatment fluid application area, before the conveyor adjusts the elevation of the receptacle.
- the treatment fluid is squeezed from the fibres in the receptacle during or after the application of fluid.
- Reference to a plunger throughout this specification should be understood to refer to a means of pressing against the fibres so as to facilitate in the egress of treatment fluid.
- the plunger is in the form of a plate of sufficient shape and surface area so as to fit within an opening in the receptacle, while the surface area covers a significant portion of the opening.
- the plunger base may be slightly smaller than the open aperture of the receptacle.
- the plunger may be driven by any number of actuators, but preferably the drive means is a pneumatic or hydraulic piston.
- the plunger may be in the form of a plate that allows the ingress and egress of fluid while preventing the fibres from escaping in the same direction.
- the action of the plunger may be assisted by the resting of the receptacle against a drain plate.
- a drain plate throughout this specification should be understood to refer to a means of allowing fluid to pass through a surface, while preventing the passage of extraneous material.
- the receptacle includes a perforated base which may function as a drain plate.
- additional support may be required when a high pressure plunger is applied to the receptacle, and an additional drain plate in the form of a rigid, perforated flat surface With a surface area equal to or greater than the base of the receptacle may be utilised.
- the drain plate has perforations or slots of sufficient size as to prevent the passage of fibres that have inadvertently escaped the receptacle.
- the drain plate is intended to be able to withstand forces applied to it by a plunger.
- the plunger may be in the form of a perforated plate that allows the fluid to pass through the plate surface while preventing the fibres from escaping in the same direction.
- automation may be achieved by way of a central controller configured to interface with the various components to carry out preprogrammed sequences according to the material being treated, or the nature of treatment required. For example, some batches may only go through a limited number of treatment cycles, or forgo a drying stage.
- the present invention provides the advantages of: • continuous batch operation, able to process multiple lots simultaneously but separately;
- Figure 1 shows a perspective view of the present invention configured in
