DESCRIPTION

Opening and cleaning process of dirty wool.

OBJECT OF THE INVENTION

The invention is designed to card, open and beat dirty wool from sheep shearing, preferably with the purpose of cleaning said wool of impurities such as soil, seeds, vegetables or similar by opening the fibers of this dirty wool, of such that once it passes through the different stages that make up the process of the invention, it eliminates the heaviest impurities it possesses at the beginning.

The process for the opening and cleaning of dirty wool is made up of a certain number of stages that begins with the introduction of bales of dirty wool obtained in class and ends with the pressing and packing of so-called dirty wool No solid impurities.

This process or procedure is specifically divided into five stages formed in the first place by the so-called loader stage, whereby the dirty wool moves and gradually enters a wool or batter opener, which slightly opens the wool at a stage called beaten Subsequently, this resulting dirty wool is transferred to a second loader in the stage named as the second loader, which moves it and introduces it into a second wool opener, this stage has been designated as the second batting, so that the resulting dirty wool from the first cleaning it reopens and as a consequence more heavy impurities are removed. Finally, in the last stage of the press and packaging, the wool without solid impurities is transported by a certain conveyor belt until a defined batch is subjected to a pressurized packaging.

BACKGROUND OF THE INVENTION

Since time immemorial, man harvests animal and vegetable fibers to spin them and with the yarn weave coats that protect his body from the weather or similar. To achieve such spinning, a long and complex industrialization development must be followed.

Until approximately the decade of the 60, the cover or fleece, for example of the sheep, was classified to optimize the obtaining of different batches of matter, that is why once the sheared wool was obtained, this was acquired by the different companies that carried out its industrialization in different grades. In this case, the compact tufts of dirty wool obtained after shearing were shaken or beaten by a rod of 1 to 2 cm in diameter, to be previously hollowed out before washing in industrial laundries in order to remove impurities from this dirty wool.

At present, this way of proceeding continues being quite similar in spite of the improvements and new techniques that the passage of time entails, especially at the industrial level. That is why, just as in the past, dirty wool once sheared is acquired by the companies that carry out their different industrialization processes.

First of all, within the set of these industrial processes or developments, the so-called classification is carried out, which formerly consisted of classifying or separating the different fleeces by their fineness, in addition to the determination of their industrial type, and currently there are simplified systems of classification whose objective is to be able to condition and describe the sheared lot. Following the class or classification is followed by the washing of the fleeces with the objective of eliminating the substances that accompany the wool as soil, vegetable dirt, suarda, fat or similar. This washing can be done in two ways, a first cleaning called a previous wash that has as

objective to save the cost of impurity freight not considering this wool after washing as dirty wool but clean wool; and the industrial washing itself that is carried out in bats composed of 3 to 6 boats and aims to separate the fat and other foreign substances from the fibers but without removing the plant material. Subsequently, the elimination of plant materials is followed by chemical, carding, combing and finally spinning.

After doing a study of the state of the art in this regard, different records have been found among which we have highlighted the ES2035245 register entitled “Procedure for continuous washing with solvent of a wool fabric and its corresponding equipment”, in this register It protects an operation of bending of woolen fabrics, carried out by means of equipment that cleans batches of wool containing specific surfactant products by means of water baths. In this case, the cleaning is within the industrialization process that aims to clean the wool fibers for the purpose of spinning, which is why this registration is totally different from the process of the present invention, since the purpose of this is to eliminate the greater number of impurities when the wool is still dirty wool prior to its industrialization.

On the other hand, we also highlight the record ES0155723 entitled "A procedure to separate impurities and fatty substances from textile materials, for example wool or raw cotton or similar". In this case, the procedure of this registry consists in the realization of a treatment by means of solutions of lignin transformation products, using a type of soluble products for the transformation of the so-called lignin substances, that is why this registry is also totally Unlike the process of the present invention, since among the multitude of differences between the two, it is emphasized that in the process of the invention there is no presence of any type of solution or treatment for cleaning the dirty wool.

Therefore, with the process or procedure of opening dirty wool object of the present invention goes a step further in the wool industry, since with its utilization dirty wool, obtained after its shearing process and after its classification removes a large amount of dirt such as soil, seeds, vegetables or similar, without the need for washing it or its transformation or treatment by washing or laundry. It also stands out that dirty wool, when it has passed through each and every one of the stages of the process object of the invention, is still considered dirty wool but has eliminated such a number of vegetable impurities and soil that increases the quality of the product, such as the yield of This way, thus saving the freight costs of the impurities, in the same way as with the previous washing described above, but after the process of the invention in terms of dirty wool.

Ace! therefore, and taking into account the arguments set forth, we consider that the process or procedure for opening, carding and batting of dirty wool object of the present invention, is different from the methods performed in the removal of impurities from the so-called dirty wool presented until date, since with the process of the invention a type of wool called dirty is introduced, in the industrial sector, preferably sheep, with a quality and characteristics different from what is known at present.

Below is a detailed description of the invention that completes these general ideas introduced at this point.

DESCRIPTION OF THE INVENTION

The process for opening and cleaning dirty wool object of the present invention is shaped by the achievement of a certain number of stages that begins with the introduction of multiple bundles of dirty wool, obtained after shearing, and ends with pressing in addition of dirty wool packaging considerably clean of impurities.

This process is specifically divided into five stages, which begin with the so-called loader stage. This first stage consists of filling a specific loader with a structure of resistant material, whose vertical section has a "U" shape, so as to prevent laterally the dirty wool broth once it is deposited in its dirty wool. inside. The aforementioned loader, conveys the dirty wool deposited inside it at a set speed or speed, controlled by a speed variator, by means of which the speed at which the dirty wool is to be introduced or turned over in the following is regulated element that forms the process of the invention, depending on the type of dirty wool to be cleaned.

This dirty wool that still contains the impurities of the shearing, enters an element or device called a batter. This so-called batting stage moves the dirty wool to some drums, which have steel handles that open the wool as it passes through them, so that they act at a speed previously defined in the previous stage, which prevents breakage. Of the same. Simultaneously when opening the fibers of the dirty wool, the impurities are falling by gravity to the ground or deposit enabled for it, through certain grids that allow their extraction.

This resulting dirty wool, which contains less solid impurities, is moved by continuous displacement to another loader of similar characteristics.

than mentioned above. This second loader, which is part of the so-called second loader stage, transports the dirty wool from the first blender described to another element that is also a blender, that is, so that the dirty wool removes as many impurities as possible, the wool resulting from the first cleaning is moved by continuous displacement at a speed or speed controlled by a speed variator, to a second batter. The aforementioned second loader also has the first loader, a vertical plate on each side of its base that avoids the broth of the wool on the sides.

Once the wool enters the second batter, it is introduced at a constant speed, which in the same way as the one previously reviewed, the fibers of the wool pass again through steel handles arranged on some drums, with the difference that the wool dirty that is introduced in this second batsman arrives slightly open and carded with respect to the one that entered the first batsman. As a consequence, the solid particles that are still retained between the fibers fall by gravity to the ground or deposit enabled for it, as it occurs in the second stage cited herein.

Once the wool known in the sector as dirty wool has gone through the previously noted stages object of the invention, the resulting wool fibers are carded, open and beaten, so that they contain a number of impurities between their fibers considerably less than the content at the beginning of the process. That is why at the exit of the wool fibers of the second batuar they are transported by a conveyor belt that introduces them in a certain press that packs them in optimal conditions to be exported and used in the industrial sector as “dirty wool” by the different manufacturing plants that will subsequently start their industrial treatment for obtaining yarn, the latter part of the manufacturing being not the object of the invention.

To complete the description that is being made and in order to help a better understanding of the features of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting character.

In the drawings:

Figure 1 represents a configuration scheme among all the elements that make up the process for opening and cleaning dirty wool in its different stages.

Figure 2 represents in perspective both the different elements and the different stages of the figural.

DESCRIPTION OF THE DRAWINGS

The process or procedure for the opening and cleaning of dirty wool object of the present invention is formed by the achievement of a certain number of stages (a, b, c, d, e) that begins with the introduction of multiple bundles of wool Dirty (1) obtained after shearing and ends with the pressing and packing of dirty wool considerably clean of impurities (12).

This process is specifically divided into five stages, which begins with the so-called loader stage (a). This first stage consists of filling a specific magazine (2) with a structure of resistant material, whose vertical section has a “U” shape that prevents the lateral fall of the dirty wool (1) deposited from dirty wool (1) inside. Said loader (2) transports the slurry wool (1) deposited inside it at a certain speed or speed controlled by a speed variator, by means of which it is regulated by the speed at which the dirty wool must be

introduced in the next element that forms the process of the invention, depending on the type of dirty wool (1) to be cleaned.

This dirty wool (1), which still contains the impurities of the shearing, enters an element or piece called batuador (3). This so-called batting stage (b) moves the dirty wool (1) to some drums, which have steel handles that open the wool as it passes through them, so that they act at a speed previously defined in the stage previous, which prevents the breakage of it. Simultaneously when opening the fibers of the dirty wool (1), the impurities are falling by gravity to the ground or deposit (4) enabled for it (Fig. 2), through certain gratings (41) that allow their broth.

This resulting dirty wool (12), which contains less solid impurities, is moved by continuous displacement to another magazine (5) of similar characteristics than the one mentioned above. This second loader (5), which is part of the so-called second loader stage (c), transports the resulting dirty wool (12) from the first blender (3) described to another element that is also a blender (6), that is , so that the dirty wool eliminates as many impurities as possible, the wool resulting (12) from the first cleaning is moved by continuous displacement at a speed or speed, controlled by a speed variator, to a second mixer (6 ). The said second loader (5) also has the first loader (2), a vertical plate on each side of its base that avoids the wool broth on the sides.

Once the wool enters the second blender (6), it is introduced at a constant speed, which in the same way as the one previously reviewed, the fibers of the wool go through steel handles arranged on some drums, with the difference that the resulting dirty wool (12) that is introduced in this second blender (6) arrives slightly open and carded with respect to the one that entered the first blender (3), as a consequence the solid particles that are still retained between the fibers fall by gravity on the ground or deposit (7)

enabled for it through certain grilles (71) that allow its broth, as it happens in the second stage (b) described in this writing.

Once the wool known in the sector as dirty wool, has passed through the previously indicated stages object of the invention, the impure clean wool fibers (13) are carded, open and batted, so that they contain a number of impurities between its fibers considerably less than the content at the beginning of the process. That is why after the release of the wool fibers from the second blender (6), the clean wool fibers (13) are transported by a conveyor belt (8) that introduces them into a certain press (9) that packs them in optimal conditions for exportation or similar.

Described sufficiently in what precedes the nature of the invention, taking into account that the terms that have been drafted in this specification should be taken in a broad and non-limiting sense, as! as the description of the way to put it into practice, and, demonstrating that it constitutes a positive technical advance, is why the registration is requested, being what constitutes the essence of the aforementioned invention, which is then specified in the following claims .
