Abstract

A dehydrating screw press by which an advancing product to be deshydrated is pressed, by the rotating movement of one or more screw elements with a conical shaft (1) and a conical spiral (2) operating in a corresponding space up to the wall of a filtering cage (3). As the increasing diameter of the spiral (2) conforms to the like reduction of the shaft section (4), the use of the helical elements fitted side by side allows each spiral to operate with a profile extending up to the other helical element wall. Therefore, non-intermeshing zones are avoided during the dehydrating phase in the intermediate space. As the two pressing elements are rotated in opposite directions, rotation of the pressed material is avoided, thus advancing the product in an axial direction. The filtering cage used for a press with two helical elements shows a confirmity with two components (5 and 6) interconnected on lines (7 and 8) at the intermeshing area of the two spirals.

Description

Prensa de husillo de deshidratación con dos o más elementos helicoidales con perfiles entrecruzados.Dehydration spindle press with two or more helical elements with cross-linked profiles.

La presente invención se refiere a una prensa de husillo de deshidratación con dos o más elementos helicoidales, que evita las zonas de interferencia parcial de las espirales sobre el producto a tratar. Usando los elementos mencionados anteriormente uno junto al otro, se obtiene un efecto combinado de interferencia cónica, completa en el espacio intermedio entre sus ejes, con un empuje de las dos espirales entrecruzadas, con un movimiento en oposición, que obliga al avance axial del producto.The present invention relates to a press of dehydration spindle with two or more helical elements, which avoid areas of partial interference of the spirals on the product to be treated Using the elements mentioned above next to each other, you get a combined interference effect conical, complete in the intermediate space between its axes, with a thrust of the two interwoven spirals, with a movement in opposition, which forces the axial advance of the product.

Las prensas de husillo se utilizan para deshidratar materiales fibrosos que contienen líquido; son particularmente usadas en el tratamiento de la remolacha azucarera, en la deshidratación de forraje, en la extracción de aceites y producción de harina para piensos de substancias alimenticias recuperadas tal como pescado y otros. Dichas prensas utilizan dos o más elementos helicoidales que dejan avanzar el producto desde un extremo, empujándolo hacia el interior de una estructura de filtrado desde la que el líquido sale continuamente, mientras el residuo deshidratado se descarga por el otro extremo. Esto provoca un espacio de interferencia bicilíndrico de la estructura de filtrado espiral, que da lugar a zonas de no interferencia, así como otras zonas con interferencia limitada de las espirales. Esta intervención no uniforme e incluso la no intervención de la espiral no garantiza una uniformidad de presión del producto y provoca pérdidas de suministro. En particular, cuando los elementos helicoidales se usan uno junto al otro, se producen zonas de interferencia limitada e incluso de no interferencia de las espirales, en las que se pueden observar dificultades en el avance del producto. En consecuencia, éste tiende a estancarse y, en particular, debido a la sobretensión lateral causada por las espirales en estas zonas, puede producirse una acumulación con graves problemas. Además, el avance no uniforme del producto provoca espacios vacíos que aplastan y dañan los residuos deshidratados. Por tanto, se puede afirmar que la velocidad que permite la instalación no puede aprovecharse en su totalidad porque debe estar continuamente de acuerdo con el producto a tratar y porque la producción debe verificarse continuamente para permitir una intervención a tiempo. En efecto, GB-A-677794 describe una prensa de husillo de deshidratación con dos elementos helicoidales con perfil constante, como se define en el preámbulo de la reivindicación 1.Spindle presses are used to dehydrate fibrous materials that contain liquid; They are particularly used in the treatment of sugar beet, in dehydration of fodder, in the extraction of oils and Flour production for feedstuffs recovered such as fish and others. These presses use two or more helical elements that let the product advance from a end, pushing it into a filtering structure from which the liquid leaves continuously, while the residue Dehydrated is discharged from the other end. This causes a bicylindrical interference space of the filtering structure spiral, which results in areas of non-interference, as well as others areas with limited spiral interference. This intervention non-uniform and even non-intervention of the spiral does not guarantee a uniform pressure of the product and causes losses of supply. In particular, when helical elements are used next to each other, there are areas of limited interference and even of non-interference of the spirals, in which you can observe difficulties in the advancement of the product. In consecuense, this tends to stagnate and, in particular, due to overvoltage lateral caused by spirals in these areas, may occur an accumulation with serious problems. In addition, the uneven advance of the product causes empty spaces that crush and damage the dehydrated waste Therefore, it can be said that the speed which allows installation cannot be fully utilized because you must continually agree with the product to be treated and because production must be continuously verified to allow an intervention on time. Indeed, GB-A-677794 describes a press of dehydration spindle with two helical elements with profile constant, as defined in the preamble of the claim one.

Estos inconvenientes se evitan con una prensa de husillo de deshidratación con dos elementos helicoidales con perfil constante, que trabajan en una estructura de filtrado de acuerdo con su espacio de interferencia, como se define en la reivindicación 1, la cual asegura la uniformidad en la acción de presión de la espiral del elemento helicoidal que está funcionando constantemente con interferencia de espacio al límite de la pared. En el espacio intermedio entre los ejes de los elementos helicoidales dispuestos uno junto al otro, el sistema permite el efecto combinado de interferencia completa con empuja de las partes entrecruzadas de las espirales que giran en oposición, que fuerza el movimiento axial hacia adelante del producto. En conexión, puesto que no hay zonas sin interferencia o con interferencia limitada, el sistema permite ajustar el suministro a la velocidad de los propulsores. En particular, el espacio más pequeño existente en la parte intermedia central entre los dos elementos helicoidales, realizado de acuerdo con la invención, en comparación con el existente en la ya mencionada unión con interferencia de cono truncado, evita la acumulación de producto: por el contrario, puesto que las dos espirales de intersección funcionan con interferencia completa hasta el límite de la pared de los dos ejes, se asegura el movimiento axial gradual del producto.These inconveniences are avoided with a press dehydration spindle with two helical elements with profile constant, working in a filtering structure according to its interference space, as defined in claim 1, which ensures uniformity in the pressure action of the spiral of the helical element that is constantly running with space interference to the wall limit. In the space intermediate between the axes of the helical elements arranged next to each other, the system allows the combined effect of complete interference with pushing of the cross-linked parts of the spirals that rotate in opposition, which forces axial movement Forward of the product. In connection, since there are no zones without interference or with limited interference, the system allows adjust the supply to the speed of the thrusters. In particular, the smallest space existing in the intermediate part central between the two helical elements, made according with the invention, compared to the existing one in the already mentioned union with truncated cone interference, prevents product accumulation: on the contrary, since the two intersection spirals work with full interference up the boundary of the wall of the two axes, movement is assured gradual axial product.

Substancialmente, el producto a deshidratar, en el movimiento de avance, es presionado por el movimiento giratorio de dos elementos de husillo con eje cónico 1 y también espiral cónica 2 -total y regular- para funcionar en un espacio de correspondencia al límite de la pared de la estructura de filtrado 3. Si los elementos helicoidales con interferencia cónica total regular se usan uno junto al otro, puesto que en ellos la elevación hacia arriba de la espiral 2 está de acuerdo con una reducción de sección 4 parecida de su eje 1, se permite que cada espiral trabaje con continuidad de perfil hasta el límite de la pared del eje del otro elemento helicoidal, evitando así zonas de no interferencia o de limitada interferencia sobre el producto a tratar en el espacio intermedio entre los ejes. Además, el movimiento en oposición de los dos o más elementos de presión provoca un efecto combinado de interferencia completa dado por las dos espirales recíprocamente entrecruzadas que fuerza el movimiento de avance axial del producto. La estructura de4 filtrado usada para la prensa con dos elementos helicoidales consta de dos componentes 5 y 6 conectados sobre líneas inclinadas convergentes 7 y 8 dispuestas en el límite de interferencia de las dos espirales entrecruzadas.Substantially, the product to be dehydrated, in the forward movement is pressed by the rotating movement of two spindle elements with conical shaft 1 and also spiral conical 2 -total and regular- to operate in a space of correspondence to the wall limit of the filtering structure 3. If helical elements with total conical interference regular they are used next to each other, since in them the elevation upward of spiral 2 agrees with a reduction of section 4 similar to its axis 1, each spiral is allowed to work with profile continuity up to the limit of the axis wall of the another helical element, thus avoiding areas of non-interference or of limited interference on the product to be treated in space intermediate between the axes. In addition, the opposition movement of the two or more pressure elements causes a combined effect of full interference given by the two spirals reciprocally cross-linked that forces the axial advance movement of the product. The filtering structure used for the press with two elements Helical consists of two components 5 and 6 connected on lines converged slopes 7 and 8 arranged at the limit of interference of the two intersecting spirals.
